In other projects, it is set to # '$srcdir', '$srcdir/..', or '$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command './configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the 'README' file for instructions specific to this package. Some packages provide this 'INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The 'configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a 'Makefile' in each directory of the package. It may also create one or more '.h' files containing system-dependent definitions. Finally, it creates a shell script 'config.status' that you can run in the future to recreate the current configuration, and a file 'config.log' containing compiler output (useful mainly for debugging 'configure'). It can also use an optional file (typically called 'config.cache' and enabled with '--cache-file=config.cache' or simply '-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how 'configure' could check whether to do them, and mail diffs or instructions to the address given in the 'README' so they can be considered for the next release. If you are using the cache, and at some point 'config.cache' contains results you don't want to keep, you may remove or edit it. The file 'configure.ac' (or 'configure.in') is used to create 'configure' by a program called 'autoconf'. You need 'configure.ac' if you want to change it or regenerate 'configure' using a newer version of 'autoconf'. The simplest way to compile this package is: 1. 'cd' to the directory containing the package's source code and type './configure' to configure the package for your system. Running 'configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type 'make' to compile the package. 3. Optionally, type 'make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type 'make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the 'make install' phase executed with root privileges. 5. Optionally, type 'make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior 'make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing 'make clean'. To also remove the files that 'configure' created (so you can compile the package for a different kind of computer), type 'make distclean'. There is also a 'make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type 'make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide 'make distcheck', which can by used by developers to test that all other targets like 'make install' and 'make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the 'configure' script does not know about. Run './configure --help' for details on some of the pertinent environment variables. You can give 'configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU 'make'. 'cd' to the directory where you want the object files and executables to go and run the 'configure' script. 'configure' automatically checks for the source code in the directory that 'configure' is in and in '..'. This is known as a "VPATH" build. With a non-GNU 'make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use 'make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple '-arch' options to the compiler but only a single '-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the 'lipo' tool if you have problems. Installation Names ================== By default, 'make install' installs the package's commands under '/usr/local/bin', include files under '/usr/local/include', etc. You can specify an installation prefix other than '/usr/local' by giving 'configure' the option '--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option '--exec-prefix=PREFIX' to 'configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like '--bindir=DIR' to specify different values for particular kinds of files. Run 'configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of '${prefix}', so that specifying just '--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to 'configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the 'make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, 'make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of '${prefix}'. Any directories that were specified during 'configure', but not in terms of '${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the 'DESTDIR' variable. For example, 'make install DESTDIR=/alternate/directory' will prepend '/alternate/directory' before all installation names. The approach of 'DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of '${prefix}' at 'configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving 'configure' the option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. Some packages pay attention to '--enable-FEATURE' options to 'configure', where FEATURE indicates an optional part of the package. They may also pay attention to '--with-PACKAGE' options, where PACKAGE is something like 'gnu-as' or 'x' (for the X Window System). The 'README' should mention any '--enable-' and '--with-' options that the package recognizes. For packages that use the X Window System, 'configure' can usually find the X include and library files automatically, but if it doesn't, you can use the 'configure' options '--x-includes=DIR' and '--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of 'make' will be. For these packages, running './configure --enable-silent-rules' sets the default to minimal output, which can be overridden with 'make V=1'; while running './configure --disable-silent-rules' sets the default to verbose, which can be overridden with 'make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX 'make' updates targets which have the same timestamps as their prerequisites, which makes it generally unusable when shipped generated files such as 'configure' are involved. Use GNU 'make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its '' header file. The option '-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put '/usr/ucb' early in your 'PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in '/usr/bin'. So, if you need '/usr/ucb' in your 'PATH', put it _after_ '/usr/bin'. On Haiku, software installed for all users goes in '/boot/common', not '/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features 'configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, 'configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the '--build=TYPE' option. TYPE can either be a short name for the system type, such as 'sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file 'config.sub' for the possible values of each field. If 'config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option '--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with '--host=TYPE'. Sharing Defaults ================ If you want to set default values for 'configure' scripts to share, you can create a site shell script called 'config.site' that gives default values for variables like 'CC', 'cache_file', and 'prefix'. 'configure' looks for 'PREFIX/share/config.site' if it exists, then 'PREFIX/etc/config.site' if it exists. Or, you can set the 'CONFIG_SITE' environment variable to the location of the site script. A warning: not all 'configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to 'configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the 'configure' command line, using 'VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified 'gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash 'configure' Invocation ====================== 'configure' recognizes the following options to control how it operates. '--help' '-h' Print a summary of all of the options to 'configure', and exit. '--help=short' '--help=recursive' Print a summary of the options unique to this package's 'configure', and exit. The 'short' variant lists options used only in the top level, while the 'recursive' variant lists options also present in any nested packages. '--version' '-V' Print the version of Autoconf used to generate the 'configure' script, and exit. '--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally 'config.cache'. FILE defaults to '/dev/null' to disable caching. '--config-cache' '-C' Alias for '--cache-file=config.cache'. '--quiet' '--silent' '-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to '/dev/null' (any error messages will still be shown). '--srcdir=DIR' Look for the package's source code in directory DIR. Usually 'configure' can determine that directory automatically. '--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. '--no-create' '-n' Run the configure checks, but stop before creating any output files. 'configure' also accepts some other, not widely useful, options. Run 'configure --help' for more details. libmicrohttpd-1.0.1/Makefile.am0000644000175000017500000004065614445225034012110 # This Makefile.am is in the public domain ACLOCAL_AMFLAGS = -I m4 SUBDIRS =

This is a correction release. This release mainly fixes and improves builds with non-default configure parameters. -- Evgeny Grin (Karlson2k) Thu 01 Feb 2024 15:00:00 CET Released GNU libmicrohttpd 1.0.0. This is the first non-bugfix release since version 0.9.75 and the first ever stable release of GNU libmicrohttpd. It is a huge one with new features and fixes. The major changes: * Rewritten parsing of clients' requests, fully aligned with current RFCs (9110 and 9112) requirements. Added detailed control of strict or lenient specification enforcement. Application may choose between more compatible mode or more strict and secure mode. * Reworked Digest Auth, greater enhanced support for current RFC 7617 features. MHD currently is the only known server-side implementation with support for SHA-512/256, userhash and username in extended notation. At the same time the very old RFC2069 is supported, as well as MD5 and SHA-256. * Improved functionality in multi-threading environment, especially with external sockets polling modes. * Reworked Basic Auth, adding new convenient API functions. * Re-implemented GnuTLS initialisation. Now supported libmicrohttpd-specific system-wide configuration, as well as generic GnuTLS system-wide configuration. Application may adjust settings based on system configuration instead of specifying its own full configuration. * Tons of other new functionality and various fixes. For detailed changes see the ChangeLog or Git commit logs. Since last non-bugfix release there are 1062 commits added with 67007 lines insertions and 26616 deletions. -- Evgeny Grin (Karlson2k) Sun 28 May 2023 18:00:00 MSK Released GNU libmicrohttpd 0.9.77. This is mostly a bugfix release. This version created by taking patches from the current development branch and back-porting them on top of version 0.9.76. The most notable changes are: some improvements for Digest and Basic authorizations, fixed efficiency for TLS upgraded connections, fixed processing of folded headers in requests, fixed functionality with blocking sockets, improved and fixed internal test-suite. The more detailed list of the important changes: API changes: + Added new function MHD_get_version_bin(). Improvements and enhancements: * Digest Auth: changed algorithm identifiers in server generated headers from "md5" / "sha-256" to "MD5" / "SHA-256" to better match RFC (while clients should use caseless matching). * Improved Base64 decoding by new implementation with robust input data validation checks. * Improved configure for cross-compiling, for better compatibility with POSIX and for better compatibility with the latest compiler versions. * New internal tests: for Base64 decoding, Basic Auth and folded headers. * Supported new libcurl API in tests to mute deprecation warnings. * Supported ARM and ARM64 for VC compilers. Functionality changes: * any negative number returned by response data generation callback function is treated as an error. Previously negative values except predefined error codes could produce undefined behaviour. * Added handling of "DEBUG" preprocessor macro as an alias of "_DEBUG". Fixes: # Fixed functionality with blocking sockets. # Fixed very inefficient data pumping for upgraded TLS connections. # Fixed processing of folded headers in the requests. # Fixed data races when closing upgraded connection. # Removed duplication of "Connection: upgrade" header. # Digest auth: fixed thread sync to avoid "stale hash" results. # Fixed harmless unwanted extra data processing resulting in triggering of the assert. # Fixed tests for LTO. # Removed removed non-portable functions in examples. # Fixed delayed call of connection notification callback in thread-per-connection mode. # Fixed Address Sanitizer unpoison of memory when memory pool is destroyed. This fixed periodic ASAN error when used for a long time with the sanitizer. # Fixed compiler warnings in library code, examples, tests and configure checks. # New TLS certificates for test-suite: all with SAN fields and SHA-256 hash. # Tests: fixed tests on Darwin 22.x (Ventura). # Tests: redesigned one tests group to avoid stress-testing of the OS. -- Evgeny Grin (Karlson2k) Sun 26 Feb 2023 17:49:30 CET Released GNU libmicrohttpd 0.9.76 hotfix. -CG This is a hotfix release. This only change since previous release is fixed potential DoS vector in MHD_PostProcessor discovered by Gynvael Coldwind and Dejan Alvadzijevic (CVE-2023-27371). While the researchers have not been able to exploit this attack vector when libmicrohttpd is compiled with the standard GNU C library, it is recommended that you update MHD as soon as possible if your applications are using (optional) MHD_PostProcessor functionality. -- Evgeny Grin (Karlson2k) Sun 26 Dec 2021 20:30:00 MSK Released GNU libmicrohttpd 0.9.75 -EG This is a correction release. The main improvement is the implementation of workaround for some OSes (like OpenBSD 7) where "monotonic" clock may jump back. Now MHD is able to automatically detect such situation and recover if the jump is small. This workaround is needed with increased accuracy of connection timeout introduced in previous version, as with lower accuracy (v0.9.73 and before) these jumpbacks were unnoticeable. Other changes: fixed some compiler, Makefile, and configure warnings on specific platforms; one test further improved. -- Evgeny Grin (Karlson2k) Sun 19 Dec 2021 18:30:00 MSK Released GNU libmicrohttpd 0.9.74 This release brings a lot of fixes and improvements, and important new features. The most significant addition is the new experimental implementation of WebSockets contributed by David Gausmann. This implementation is not fully tested yet so currently it is disabled by default. Other changes include a lot of improvements and clarifications in doxy comments in microhttpd.h header file, improved compliance with the RFC HTTP specifications, the new implementation of reply header forming, the new implementation of request chunked encoding parsing, new automatic error replies, internal optimisations, and many important fixes, including fixes for long-standing bugs. More detailed list of notable changes: API changes: + Added new function MHD_get_reason_phrase_len_for(). + Added MHD_CONNECTION_INFO_HTTP_STATUS type of information queried by MHD_get_connection_info(). + Added new response flag MHD_RF_SEND_KEEP_ALIVE_HEADER to force sending of "keep-alive" header even if not required by RFC. + Added new response creation function MHD_create_response_from_buffer_with_free_callback_cls() with custom cleanup callback. + Added new response flag MHD_RF_HTTP_1_0_COMPATIBLE_STRICT with the same functionality as existing MHD_RF_HTTP_VERSION_1_0_ONLY flag. The old flag will be deprecated. + Added new response flag MHD_RF_HTTP_1_0_SERVER with the same functionality as existing MHD_RF_HTTP_VERSION_1_0_RESPONSE flag. The old flag will be deprecated. New features: + Added experimental WebSockets extension with separate header. Disabled by default as it is not fully tested yet. + Added '--enable-sanitizers[=address,undefined,leak,user-poison]' configure parameter (instead of '--enable-sanitizer'), implemented custom memory poisoning for memory pools. Improvements and enhancements: * Doxy function descriptions was corrected, clarified, extended, and improved. Now it should be much easier to learn MHD just by reading the headers. * Completely rewritten reply header forming. New implementation is more robust, simpler maintainable and expandable, and better follows RFC HTTP specifications. * Performance improvements: now HTTP version and request method are decoded one time only (previously MHD used string comparison many times during processing the data). * Rewritten request chunked payload decoding. The new implementation better conforms to the HTTP RFC, detects format problems earlier, replies to the clients with description of detected problems, handles untypical (but syntactically correct) values properly. * Added special replies for wrong/unsupported HTTP versions in requests, broken HTTP chunked encoding in requests, * As required by HTTP RFC, added automatic error replies if client used broken chunked encoding, too large chunk size, too large payload size, or broken Content-Length header. * Optimized connection's memory pool handling. * Changed timeout precision from one second to one millisecond. * Added some checks for incorrect user data, reporting problems in MHD log. * Improved performance of hash calculations functions by using compiler built-ins (if available). * Implemented SHA-1 calculations (required for WebSockets). * Added universal MSVC project that works with any (sufficiently new) version of MSVC. * Developed simple HTTP client to test MHD under very special conditions. * Implemented 45 new tests. * Improved existing tests to test more aspects of MHD. * Added check for correct results of system and libcurl functions. * Response headers are checked during forming of responses. * HTTPS tests were improved. * Added rebuild on W32 of all required files if files are missing. * Many internal optimisations and improvements. Functionality changes: * Keep-alive header is omitted by default for HTTP/1.1 connections. Use of header can be enforced by response flag. * Chunked encoding is used for HTTP/1.1 non-keep-alive connections for responses with unknown size. Previously MHD used "indication of the end of the response by closing connection" in such cases, however it is not correct for HTTP/1.1 connections as per HTTP RFC. * As required by HTTP RFC, use HTTP/1.1 version instead of HTTP/1.0 in reply headers when client is HTTP/1.0 . HTTP/1.0 version can be enforced by response flag. * User response headers are used in replies in the same order as was added by application. * Allowed tab characters in response header values. * All custom "Connection:" response headers are automatically combined into single "Connection:" header. * "keep-alive" token silently dropped from custom "Connection:" response header. "Keep-alive" cannot be enforced and used automatically if possible. * Allow tab character in custom response header value. * Disallow space character in custom response header value. * Do not allow responses with 1xx codes for HTTP/1.0 requests. * Detected and reported incorrect "Upgrade" responses. * W32 targets are changed to Vista+ by default. XP is supported still. Fixes: # Fixed short busy-waiting (up to one second) when connection is going to be expired and closed. # Fixed handling of errors during start of new connection, fixed inability to accept new connections in thread-per-connection mode due to the missing decrement of number of daemon's connections if start of new thread is failed. # Fixed incorrect parsing of LFLF, LFCR, CRCR, and bare CR as single linefeed in request header and request chunked payload. Now only CRLF or bare LF are recognized as linefeed. # Fixed response chunked encoding handling. Now it works properly with non-keep-alive connection, with fixed size replies (if chunked was enforced by header), and in other situations. # Other fixes for chunked replies. # Fixed handling of custom connection timeout in thread-per- connection mode. # Fixed wrongly used MHD_REQUEST_TERMINATED_COMPLETED_OK code for application notification when MHD_REQUEST_TERMINATED_WITH_ERROR code must be used. # Fixed code MHD_REQUEST_TERMINATED_READ_ERROR not reported (code MHD_REQUEST_TERMINATED_WITH_ERROR was incorrectly used instead). # Fixed handling of request chunked encoding with untypical formatting. # Fixed processing of last part of hex-encoded values under certain conditions. # Fixed value returned for MHD_CONNECTION_INFO_REQUEST_HEADER_SIZE. # Fixed returned value for MHD_FEATURE_AUTOSUPPRESS_SIGPIPE on W32, now it is MHD_YES as W32 does not need SIGPIPE suppression. # Fixed portability of bitwise NOT for enums values. # Fixed SHA-256 and MD5 calculations with unaligned data. # Fixed incorrect caseless matching for HTTP version. # Fixed incorrect caseless matching for request method. # Fixed compatibility with old GnuTLS versions. # Fixed compiler warnings on 32-bits platforms. # Fixed blocking sockets setting in tests and examples for W32. # Fixed examples to really use libmagic if present. # HTTPS tests were fixed. # Fixed libcurl test with case-insensitive match for HTTP methods, method names must use case-sensitive match. # Fixed tests compatibility with old libcurl versions. # Fixed build on W32 with llvm-dlltool (this tool is too oversimplified) -- Evgeny Grin (Karlson2k) Sun 25 Apr 2021 14:00:00 MSK Released GNU libmicrohttpd 0.9.73 This release brings new features, improvements, and a few fixes. The most important addition is the new function for vector-backed responses, based on the patch contributed by NASA engineers. Other changes include compatibility with autoconf 2.70+, improved testsuite compatibility with CI systems, fixed and improved MSVC builds, and implementation of ALPN support. More detailed list of notable changes: API changes: + Added new function MHD_create_response_from_iovec(), based on the patch provided by Lawrence Sebald and Damon N. Earp from NASA. + Added MHD_OPTION_SIGPIPE_HANDLED_BY_APP daemon option. + Added new function MHD_run_wait(). + Added MHD_OPTION_TLS_NO_ALPN to disable usage of ALPN even if it is supported by TLS library. New features: + Added '--enable-heavy-tests' configure parameter (disabled by default). + Implemented support for ALPN. Improvements and enhancements: * Return timeout of zero also for connections awaiting cleanup. * Compatibility with autoconf >=2.70, used new autoconf features. * Warn user when custom logger option is not the first option. * Added information to the header about minimal MHD version when particular symbols were introduced. * Updated test certificates to be compatible with modern browsers. * Added on-fly detection of UNIX domain sockets and pipes, MHD does not try to use TCP/IP-specific socket options on them. * Report more detailed error description in the MHD log for send and receive errors. * Enabled bind port autodetection for MSVC builds. Fixes: # Fix PostProcessor to always properly stop iteration when application callback tells it to do so. # Fixed MD5 digest authorization broken when compiled without variable length arrays support (notably with MSVC). # Fixed detection of type of send errors on W32. -- Evgeny Grin (Karlson2k) Mon 28 Dec 2020 21:36:00 MSK Released GNU libmicrohttpd 0.9.72 This release is mostly a bugfix release, with greatly improved compatibility with various OSes/kernels, including FreeBSD, Windows, OpenBSD, NetBSD, Darwin (macOS), Solaris. Performance is improved, especially with HTTPS connections and stay-alive HTTP connections. Notable changes since version 0.9.71: API changes: + New function MHD_create_response_from_pipe() Improvements and enhancements: * Fully rewritten code for buffering/pushing from kernel network buffers for compatibility with various OSes. Reduced number of additional sys-calls, network is better utilized, responses are delivered faster. * Restored optimal sendfile() usage on FreeBSD. * MHD now takes care about SIGPIPE handling by blocking it in internal threads and avoiding functions (like sendfile()) that could generate SIGPIPE when blocking of this signal is not possible. Fixes: # Fixed crash in PostProcessor. # Fixed several resources leaks in corner cases. # Improved thread sync, thread safety and fixed one use-after-free under special conditions during stopping of daemon. # Updated HTTP status codes, header names and methods from the registries. # Fixed functioning without listen socket and with internal threads. # Fixed streaming of chunked responses for both HTTP and HTTPS. # Various compatibility fixes. -- Evgeny Grin (Karlson2k) Tue Jan 9 20:52:48 MST 2007 Project posted. libmicrohttpd-1.0.1/src/0000755000175000017500000000000014566140217010713 5libmicrohttpd-1.0.1/src/include/0000755000175000017500000000000014566140216012335 5libmicrohttpd-1.0.1/src/include/Makefile.am0000644000175000017500000000037614417460232014315 # This Makefile.am is in the public domain SUBDIRS = . include_HEADERS = microhttpd.h noinst_HEADERS = microhttpd2.h microhttpd_tls.h if HAVE_EXPERIMENTAL include_HEADERS += microhttpd_ws.h endif EXTRA_DIST = platform.h autoinit_funcs.h mhd_options.h libmicrohttpd-1.0.1/src/include/microhttpd_ws.h0000644000175000017500000013324114441373361015321 /* This file is part of libmicrohttpd Copyright (C) 2021 Christian Grothoff (and other contributing authors) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version.

MHD is a small * HTTP daemon library. As such, it does not have any API for logging * errors (you can only enable or disable logging to stderr). Also, * it may not support all of the HTTP features directly, where * applicable, portions of HTTP may have to be handled by clients of * the library. * * The library is supposed to handle everything that it must handle * (because the API would not allow clients to do this), such as basic * connection management; however, detailed interpretations of headers * -- such as range requests -- and HTTP methods are left to clients. * The library does understand HEAD and will only send the headers of * the response and not the body, even if the client supplied a body. * The library also understands headers that control connection * management (specifically, "Connection: close" and "Expect: 100 * continue" are understood and handled automatically). * * MHD understands POST data and is able to decode certain formats * (at the moment only "application/x-www-form-urlencoded" and * "multipart/formdata"). Unsupported encodings and large POST * submissions may require the application to manually process * the stream, which is provided to the main application (and thus can be * processed, just not conveniently by MHD). * * The header file defines various constants used by the HTTP protocol. * This does not mean that MHD actually interprets all of these * values. The provided constants are exported as a convenience * for users of the library. MHD does not verify that transmitted * HTTP headers are part of the standard specification; users of the * library are free to define their own extensions of the HTTP * standard and use those with MHD. * * All functions are guaranteed to be completely reentrant and * thread-safe (with the exception of #MHD_set_connection_value, * which must only be used in a particular context). * * * @defgroup event event-loop control * MHD API to start and stop the HTTP server and manage the event loop. * @defgroup response generation of responses * MHD API used to generate responses. * @defgroup request handling of requests * MHD API used to access information about requests. * @defgroup authentication HTTP authentication * MHD API related to basic and digest HTTP authentication. * @defgroup logging logging * MHD API to mange logging and error handling * @defgroup specialized misc. specialized functions * This group includes functions that do not fit into any particular * category and that are rarely used. */ #ifndef MHD_MICROHTTPD_H #define MHD_MICROHTTPD_H #ifdef __cplusplus extern "C" { #if 0 /* keep Emacsens' auto-indent happy */ } #endif #endif /** * Current version of the library in packed BCD form. * @note Version number components are coded as Simple Binary-Coded Decimal * (also called Natural BCD or BCD 8421).

They may not exist on some * platforms. Instead use uint_fast32_t. * It is also better for future-proof. * - check portability for embedded platforms. Some of them support * 64 bits, but 'int' could be just 16 bits resulting of silently * dropping enum values higher than 65535. * => in general, more functions, fewer enums for setup * * - Avoid returning pointers to internal members. It is not thread-safe and * even in single thread the value could change over the time. Prefer pointers to * app-allocated memory with the size, like MHD_daemon_get_static_info(enum * MHD_enum_name info_type, void *buf, size_t buf_size). * => Except in cases where zero-copy matters. * * - Use separate app calls/functions for data the will not change for the * lifetime of the object and dynamic data. The only difference should be the * name. Like MHD_daemon_get_static_info(enum MHD_enum_name info_type, void *buf, * size_t buf_size) MHD_daemon_get_dynamic_info(enum MHD_enum_name info_type, * void *buf, size_t buf_size) Examples of static data: listen socket, number of * workers, daemon flags. Examples of dynamic data: number of connections, * quiesce status. It should give a clear idea whether the data could be changed * over the time (could be not obvious for some data) and thus may change the * approach how to use the data in app. The same for: library, daemon, * connection, request. Not sure that dynamic data makes sense for the library. * * - Use clear separation between connection and request. Do not mix the kind * data in the callbacks. Currently we are mixing things in * MHD_AccessHandlerCallback and MHD_RequestCompletedCallback. Instead of * pointers to struct MHD_Connection we should use pointers to (new) struct * MHD_Request. Probably some other functions are mixing the things as well, to * be re-checked. * * - Define default response code in response object. There are a very little * chance that response body designed for 404 or 403 codes will be used with * 200 code. However, the responses body for 307 and 308 could be the same. So: * * add default response code in response object. Use zero for default 200. * * When app sending the response use zero for response's default code or * use specific code to override response's default value. * * - Make responses unmodifiable after first use. It is not thread-safe. * MHD-generated headers (Date, Connection/Keep-Alive) are again * part of the *request* and do not count as part of the "response" here. * * - Remove "footers" from responses. With unmodifiable responses everything should be "headers". * Add footers to *requests* instead. * * - Add API for adding request-specific response headers and footers. To * simplify the things it should just copy the strings (to avoid dealing with * complicated deinit of possible dynamic strings). After this change it should * be possible to simplify DAuth handling as response could be reused (currently * 403 responses are modified for each reply). * * - Control response behaviour mainly by response flags, not by additional * headers (like MHD_RF_FORCE_CLOSE instead of "Connection: close"). * It is easier for both: app and MHD. * * - Move response codes from MHD_HTTP_xxx namespace to MHD_HTTP_CODE_xxx * namespace. It already may clash with other HTTP values. * * - plus other things that was discussed already, like avoiding extra calls * for body-less requests. I assume it should be resolved with fundamental * re-design of request/response cycle handling. * * - Internals: carefully check where locking is really required. Probably * separate locks. Check out-of-thread value reading. Currently code assumes * atomic reading of values used in other threads, which mostly true on x86, * but not OK on other arches. Probably use read/write locking to minimize * the threads interference. * * - figure out how to do portable variant of cork/uncork * * NEW-CG: * - Postprocessor is unusable night-mare when doing "stream processing" * for tiny values where the application basically has to copy together * the stream back into a single compact heap value, just making the * parsing highly more complicated (see examples in Challenger) * * - non-stream processing variant for request bodies, give apps a * way to request the full body in one buffer; give apps a way * to request a 'large new allocation' for such buffers; give apps * a way to specify a global quota for large allocations to ensure * memory usage has a hard bound * * - remove request data from memory pool when response is queued * (IF no callbacks and thus data cannot be used anymore, or IF * application permits explictly per daemon) to get more space * for building response; * * * TODO: * - varargs in upgrade is still there and ugly (and not even used!) * - migrate event loop apis (get fdset, timeout, MHD_run(), etc.) */ #ifndef MICROHTTPD2_H #define MICROHTTPD2_H #ifdef __cplusplus extern "C" { #if 0 /* keep Emacsens' auto-indent happy */ } #endif #endif /* While we generally would like users to use a configure-driven build process which detects which headers are present and hence works on any platform, we use "standard" includes here to build out-of-the-box for beginning users on common systems.

The goal is to expose problems in MHD's error handling (by introducing random syntax errors). socat is used to listen on port 11081 and forward the randomzied stream to port 11080 where MHD is waiting. As a result, the testcases in this directory do NOT check that whatever CURL returns is what was expected -- random modifications to the TCP stream can have random effects ;-). Testcases "fail" if the code crashes or hangs indefinitely. libmicrohttpd-1.0.1/src/testzzuf/mhd_debug_funcs.c0000644000175000017500000000551214445225054016013 /* This file is part of GNU libmicrohttpd Copyright (C) 2022 Evgeny Grin (Karlson2k) GNU libmicrohttpd is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version.

GNU libmicrohttpd only implements the HTTP 1.1 protocol. The main application must still provide the application logic to generate the content. GNU libmicrohttpd is dual-licensed under the GNU Lesser General Public License (LGPLv2.1+) and the eCos License. See COPYING for details. Joining GNU =========== This is a GNU program, developed by the GNU Project and part of the GNU Operating System. If you are the author of an awesome program and want to join us in writing Free Software, please consider making it an official GNU program and become a GNU maintainer. You can find instructions on how to do so at http://www.gnu.org/help/evaluation. We are looking forward to hacking with you! Installation ============ See INSTALL for generic installation instructions. If you are using Git, run "./bootstrap" to create configure. In order to run the testcases, you need a recent version of libcurl. libcurl is not required if you just want to install the library. Especially for development, do use the MHD_USE_ERROR_LOG option to get error messages. Configure options ================= If you are concerned about space, you should set "CFLAGS" to "-Os -fomit-frame-pointer" to have gcc generate tight code. You can use the following options to disable certain MHD features: --disable-https: no HTTPS / TLS / SSL support (significant reduction) --disable-messages: no error messages (they take space!) --disable-postprocessor: no MHD_PostProcessor API --disable-dauth: no digest authentication API --disable-epoll: no support for epoll, even on Linux The resulting binary should be about 30-40k depending on the platform. Portability =========== The latest version of libmicrohttpd will try to avoid SIGPIPE on its sockets. This should work on OS X, Linux and recent BSD systems (at least). On other systems that may trigger a SIGPIPE on send/recv, the main application should install a signal handler to handle SIGPIPE. libmicrohttpd should work well on GNU/Linux, W32, FreeBSD, Darwin, NetBSD, OpenBSD, Solaris/OpenIndiana, and z/OS. Note that HTTPS is not supported on z/OS (yet). We also have reports of users using it on vxWorks. Development Status ================== This is a beta release for libmicrohttpd. Before declaring the library stable, we should have testcases for the following features: - HTTP/1.1 pipelining (need to figure out how to ensure curl pipelines -- and it seems libcurl has issues with pipelining, see http://curl.haxx.se/mail/lib-2007-12/0248.html) - resource limit enforcement - client queuing early response, suppressing 100 CONTINUE - chunked encoding to validate handling of footers - more testing for SSL support - MHD basic and digest authentication In particular, the following functions are not covered by 'make check': - mhd_panic_std (mhd_panic.c); special case (abort) - parse_options (daemon.c) - MHD_get_version (daemon.c) Note that the working library is in src/microhttpd/ with the API in src/include/microhttpd.h. An *experimental* (read: not yet working at all) newer implementation is in src/lib/, with the new API in src/include/microhttpd2.h. The experimental code will need MUCH more testing and development, you are strongly advised to stick to microhttpd.h unless you are a MHD developer! libmicrohttpd-1.0.1/configure.ac0000644000175000017500000060144414566137250012346 # This file is part of libmicrohttpd. # (C) 2006-2021 Christian Grothoff (and other contributing authors) # (C) 2014-2024 Evgeny Grin (Karlson2k) # # libmicrohttpd is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published # by the Free Software Foundation; either version 3, or (at your # option) any later version. # # libmicrohttpd is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Especially useful with MHD_USE_AUTO flag. -EG Thu Mar 16 23:12:07 MSK 2017 Idle connection should be disconnected *after* "timeout" number of second, not *before* this number. -EG/VT Thu Mar 16 22:31:54 MSK 2017 Unified update of last activity on connections. Update last activity only if something is really transmitted. Update last activity each time when something is transmitted. Removed early duplicated check for timeout on HTTPS connections. Removed update of last active time for connections without timeout. Fixed reset of timeout timer on resumed connections. Fixed never-expired timeouts on HTTPS connections. Fixed thread-safety of MHD_set_connection_option(). -EG Thu Mar 16 21:05:08 MSK 2017 Fixed minor bug resulted in slight slowdown of HTTPS connection handshake. -EG Thu Mar 16 20:35:59 MSK 2017 Improved thread-safety for DL-lists. -EG Thu Mar 16 17:55:01 MSK 2017 Fixed thread-safety of MHD_get_daemon_info() for MHD_DAEMON_INFO_CURRENT_CONNECTIONS. -EG Thu Mar 16 16:49:07 MSK 2017 Added ability to get actual daemon flags via MHD_get_daemon_info(). Fixed test_upgrade to work in request mode. Fixed compiler warnings in test_upgrade. -EG Wed Mar 15 23:29:59 MSK 2017 Prevented socket read/write if connection is suspended. Added missing resets of 'connection->in_idle'. Reworked handling of suspended connection: ensure that connection is not disconnected by timeout, always updated read/write states right after suspending. -EG Wed Mar 15 21:02:26 MSK 2017 Added new enum value MHD_CONNECTION_INFO_CONNECTION_TIMEOUT to get connection timeout by MHD_get_connection_info(). -EG Sat Mar 11 12:03:45 CET 2017 Fix largepost example from tutorial to properly generate error pages. -CG Fix largepost example, must only queue replies either before upload happens or after upload is done, not while upload is ongoing Fri Mar 10 16:37:12 CET 2017 Fix hypothetical integer overflow for very, very large timeout values. -CG Fri Mar 10 16:22:54 CET 2017 Handle case that we do not listen at all more gracefully in MHD_start_daemon() and not pass '-1' to helper functions that expect a valid socket. -CG Tue Mar 7 12:11:44 BRT 2017 Updates file `.gitignore`. Tue Mar 7 10:37:45 BRT 2017 Updated the MHD_OPTION_URI_LOG_CALLBACK's documentation. Mon Mar 6 21:46:59 BRT 2017 Added the i18n example fixing #4924. -SC Wed Mar 1 23:47:05 CET 2017 Minor internal optimisations. Changed closure connection monitoring logic: now all connections are monitored for OOB data (which treated as error), connections are not monitored any more for incoming data if incoming data is not required for processing. except_fd_set is not optional now for MHD_get_fdset(), MHD_get_fdset2() and MHD_run_from_select(). Improved connection processing in epoll mode: now connection can process both read and write each turn. Updated HTTP response codes; updated and added all missing standard HTTP headers names (and headers categories); updated and added all missing standard and additional HTTP methods. Now MHD return status MHD_HTTP_REQUEST_HEADER_FIELDS_TOO_LARGE (431) instead of old MHD_HTTP_REQUEST_ENTITY_TOO_LARGE (413) for very long header. Reworked handling of data pending in TLS buffers, resolved busy-waiting if incoming data is pending in TLS buffers and connection is in LOOP_INFO_WRITE mode. Do not clear 'ready' flag in epoll mode if send()/recv() result is EINTERRUPTED. Better detection of unready connection state: used less number of calls of recv()/send() in epoll mode. Configure: do not run gcrypt and GnuTLS tests if HTTPS is disabled by configure parameter. Fixed wrong value returned by MHD_get_timeout(). All double-linked lists now walked from tail to head. As new items are added to head, this result in more uniform processing time. Improved sockets errors handling in epoll mode. OOB data on 'upgraded' sockets is treated as error. -EG Thu Feb 16 11:20:05 CET 2017 Replace tsearch configure check with code from gnulib. -CG Wed Feb 15 13:35:36 CET 2017 Fixing a few very rare race conditions for thread-pool or thread-per-connection operations during shutdown. Various minor cosmetic improvements. Fixed #4884 and #4888 (solaris portability issues). -CG Wed Feb 08 22:33:10 MSK 2016 Ported test_quiesce_stream to W32. Improved precompiler flags selection of OpenBSD. Fixed sending responses backed by files not supported by sendfile(). Fixed thread safety for responses backed by file FD. Updated fileserver_example. Improved handling of 'upgraded' TLS forwarding in select() and poll() modes. Fixed processing of incoming TLS data in epoll mode if more than 128 connections are active. Fixed accepting more than 128 incoming connection in epoll mode. Improved test_large_put, added poll() and epoll testing. Added test_large_put_inc for testing of incremental buffer processing. Rewritten epoll connection processing logic: handle all connection one time per turn instead of trying to handle all active connection until all pending data is dried. Result is more uniform connection processing period. -EG Wed Nov 23 15:24:10 MSK 2016 Used SO_REUSEADDR (on non-W32) alongside with SO_REUSEPORT if option MHD_OPTION_LISTENING_ADDRESS_REUSE was set. -EG Wed Nov 23 12:48:23 MSK 2016 Move all gettext-related staff to 'po' subdirectory. Excluded gettext files generation from normal build. Removed generated files from GIT. -EG Tue Nov 15 19:08:43 MSK 2016 Fixed forwarding "upgraded" TLS connections for chunks sizes larger than buffer size. -EG Mon Nov 14 22:18:30 MSK 2016 Fixed unintentional usage of SO_REUSEADDR on W32. Added support for SO_EXCLBIND on Solaris. Fixed using MHD with MHD_OPTION_LISTENING_ADDRESS_REUSE on Linux kernels before 3.9 (longterm 3.2 and 3.4 are still supported). -EG Sun Nov 13 19:16:38 CET 2016 Fixed a few race issues on suspend-resume in cases where the application uses threads even though MHD did not (or at least had no internal need for locking). Also fixed DLL handling of the timeout list, avoiding manipulating it for suspended connections. Finally, eliminated calling application logic on suspended connections (which before could happen under certain circumstances). -CG Thu Nov 11 20:49:23 MSK 2016 Added support for various forms of pthread_attr_setname_np() so thread names will be set more efficiently on certain platforms (Solaris, NetBSD etc.) -EG Thu Nov 10 21:50:35 MSK 2016 Added rejection in MHD_start_daemon() of invalid combinations of daemon flags. Added MHD_USE_AUTO and MHD_USE_AUTO_INTERNAL_THREAD for automatic selection of polling function depending on platform capabilities and requested mode. -EG Thu Nov 10 17:49:56 MSK 2016 Ported "upgrade" tests to W32 and other platforms, used "gnutls-cli" instead of "openssl" in tests, minor bugs fixed, added verbose reporting if requested. "Upgrade" processing - changed internal handling logic, improved and refactored, bugs fixed, fixed sigpipe on Darwin, added printing error to log, fixed compilation without HTTPS. Added 'configure' parameter "--disable-httpupgrade" for building minimal-sized MHD versions. Added feature check "MHD_FEATURE_UPGRADE". Responses destroyed (freed) earlier if possible. Added many remarks in code comments about thread safety. Some data races and other multithread-related issues are fixed, including usage of closed sockets (may resulted in accidental closing of wrong socket). SO_NOSIGPIPE is used on all platform which support it, not only on Darwin. Added support for suspending connections in thread-per-connection mode (itself almost useless, mostly to unify modes support). Fixed Inter-Thread Communication channel usage in epoll modes. Reworked daemon cleanups and handling MHD_stop_daemon(): resources are freed only by specific threads, data races and other fixes. Started usage of C99 standard 'bool' where supported with fallback to 'int'. Renamed many MHD flags. Now they are self-explainable and more obvious, like MHD_USE_INTERNAL_POLLING_THREAD instead of MHD_USE_SELECT_INTERNALLY. Old flag names are supported for backward compatibility. Improved processing of "fast" connections: now full sequence "read request - send reply headers - send reply body" is processed after single select()/poll(). If connection is slow, request is huge or response in not immediately ready - connection will be processed in "traditional" way. Added usage of "calloc()" where supported. Minor documentation fixes. Minor improvements and fixes. -EG "Upgrade" test fixes. Documentation updated. Added HTTP "Upgrade" example. -CG Mon Oct 17 19:08:18 CEST 2016 Fixed misc. issues relating to upgrade. Releasing experimental 0.9.52. -CG Wed Oct 12 14:26:20 CEST 2016 Migrated repository from Subversion to Git. -CG Tue Oct 11 18:09:56 CEST 2016 Deprecated MHD_USE_SSL, use MHD_USE_TLS instead. -CG Tue Oct 11 18:14:40 MSK 2016 Code internal refactoring: 'pipes' renamed to 'inter-thread communication (channels)/ITCs', as code can use different types of communications. Optimizations: ITCs now always created in non-blocking mode. Added configure parameter to choose ITC type. Updated documentation and comments. Minor errors fixed (related to heavy load). -EG Thu Sep 22 17:51:04 CEST 2016 Implementing support for eventfd() instead of pipe() for signaling (on platforms that support it); fixing #3557. -CG Thu Sep 22 11:03:43 CEST 2016 Simplify internal error handling logic by folding it into the MHD_socket_close_, MHD_mutex_lock_, MHD_mutex_unlock_ and MHD_mutex_destroy_ functions. -CG Tue Sep 13 22:20:26 MSK 2016 Added autoconf macro to enable maximum platform features. Fixed compiling on Solaris. -EG Wed Sep 7 12:57:57 CEST 2016 Fixing #4641. -Hawk Wed Sep 7 00:28:59 CEST 2016 Adding remaining "_"-markups for i18n (#4614). -CG Tue Sep 6 23:39:56 CEST 2016 Allow out-of-order nonces for digest authentication (#4636). -CG Tue Sep 6 21:29:09 CEST 2016 Martin was right, "socket_context" should be "void *" in `union MHD_ConnectionInfo`. -MS Sun Sep 4 18:16:32 CEST 2016 Fixing potential memory leak (#4634). -CG Sun Sep 4 17:25:45 CEST 2016 Tests for "Upgrade" logic are now in place and passing. However, still need to make sure code is portable. -CG Sat Sep 3 11:56:20 CEST 2016 Adding logic for handling HTTP "Upgrade" in thread-per-connection mode. Also still untested. -CG Sat Aug 27 21:01:43 CEST 2016 Adding a few extra safety checks around HTTP "Upgrade" (against wrong uses of API), and a testcase. -CG Sat Aug 27 20:07:53 CEST 2016 Adding completely *untested* logic for HTTP "Upgrade" handling. -CG Sat Aug 27 18:20:38 CEST 2016 Releasing libmicrohttpd 0.9.51. -CG Tue Aug 23 22:54:07 MSK 2016 Internal refactoring: W32 compatibility layer was finally replaced with several specialized abstraction layers for sockets, control pipes (inter-thread communication) and generic functions. Now all major platform functions (including threads and mutex) are implemented in thin abstraction layers. Improved performance on W32 due to eliminating translation of error to POSIX codes and using W32 codes directly (through macros). Improved error reporting on all platforms. Improved error handling and reporting on Darwin. Minor fixes. -EG Tue Aug 16 15:14:30 MSK 2016 Minor improvement for monotonic clock. Minor configure fix for non-bash shells. -EG Mon Aug 15 13:06:52 CEST 2016 Fixed possible crash due to write to read-only region of memory given ill-formed HTTP request (write was otherwise harmless, writing 0 to where there was already a 0). Fixed issue with closed connection slots not immediately being available again for new connections if we reached our connection limit. Avoid even accept()ing connections in certain thread modes if we are at the connection limit and MHD_USE_PIPE_FOR_SHUTDOWN is available. -CG Wed Aug 10 16:42:57 MSK 2016 Moved threads, locks and mutex abstraction to separate files, some minor errors fixed, added support for thread name functions on various platforms, added configure flag for disable thread naming. -EG Sat Jul 23 20:45:51 CEST 2016 Added macro detection of speed/size compiler optimization. Added different implementation of functions in mhd_str.c for size optimization. Enabled automatically if compiler size optimization is detected or MHD_FAVOR_SMALL_CODE is defined. Added unit tests for all mhd_str.c functions. -EG Sat Jul 16 21:54:49 CEST 2016 Warn user if they sent connection into blocking state by not processing all POST data, not suspending, and not running in external select mode. -CG Fri Jul 8 21:35:07 CEST 2016 Fix FIXME in tutorial. -CG Fri Jul 8 15:57:06 CEST 2016 Adding support for 308 status code. -CG Sat Jun 25 13:49:31 CEST 2016 Use shutdown to trigger select on NetBSD. -EG Thu Jun 2 09:55:50 CEST 2016 Releasing libmicrohttpd 0.9.50. -CG Wed Jun 1 21:59:34 CEST 2016 Do not send "Content-Length" header for 1xx/204/304 status codes. -CG Tue May 17 13:32:21 CEST 2016 Allow clients to determine whether a connection is suspended; introduces MHD_CONNECTION_INFO_CONNECTION_SUSPENDED. -CG/FC Sun May 15 12:17:25 CEST 2016 Fix handling system or process resource limit exhaustion upon accept(). -CG/CP Thu May 12 08:42:19 CEST 2016 Fix handling of partial writes in MHD_USE_EPOLL_LINUX_ONLY; only consider sockets returning EAGAIN as unready. -CG/CP Mon May 2 06:08:26 CEST 2016 Adding logic to help address FE performance issue as discussed on the mailinglist with subject "single-threaded daemon, multiple pending requests, responses batched". The new logic is only enabled when MHD_USE_EPOLL_TURBO is set. Note that some additional refactoring was also done to clean up the code and avoid code duplication, which may have actually fixed an unrelated issue with HTTPS and a POLL-style event loop. -CG Sat Apr 30 10:22:37 CEST 2016 Added clarifications to manual based on questions on list. -CG Sat Apr 23 20:12:01 CET 2016 Tests perf_get_concurrent and test_concurrent_stop ported to use pthread instead of fork(). Added more error detections. -EG Sat Apr 23 16:06:30 CET 2016 Improved test_quiesce test. -EG Sat Apr 23 15:39:38 CET 2016 Notify other threads in MHD_quiesce_daemon() so listen socket FD is removed from awaiting select() and poll(). -EG Sat Apr 23 14:17:15 CET 2016 Revert "shutdown trigger select" on Darwin. Fixed daemon shutdown on Darwin without "MHD_USE_PIPE_FOR_SHUTDOWN" option. -EG Fri Apr 22 14:29:28 CET 2016 Fixed race conditions when stopping quiesced daemon with thread pool. -EG Wed Apr 20 18:12:30 CET 2016 Fixed macros in sysfdsetsize.c which could prevent compiling with non-default FD_SETSIZE. Fixed comments in mhd_str.c. Updated test_post.c to not ignore specific error on W32 if libcurl is built with workaround for WinSock bug. -EG Mon Apr 18 19:35:14 CET 2016 Fixed data races leading to inability in rare situations to resume suspended connection. -EG Tue Apr 13 21:46:01 CET 2016 Removed unneeded locking for global timeout list in MHD_USE_THREAD_PER_CONNECTION mode. Added 'simplepost' and 'largepost' examples to VS projects. Added strtoXX() locale-independent replacement functions. Added more error checking and minor fixes in digest auth functions - should improve security. Ignored specific errors in 'test_post' test until libcurl will implement workaround for WinSock bug. Fixed handling of caller-supplied socket with MHD_OPTION_LISTEN_SOCKET (regression in 0.9.49). Minor fixes. Various cosmetics and comments fixes. -EG Sat Apr 09 13:05:42 CET 2016 Releasing libmicrohttpd 0.9.49. -EG Fri Apr 08 18:32:17 CET 2016 Some minor internal fixes, addition error checking and micro optimizations. Reworked usage of sockets shutdown() - now work equally on all platforms, disconnection should be "more graceful". -EG Tue Mar 15 21:52:27 CET 2016 Do not crash if pthread_create() fails. -DD Tue Mar 15 20:29:34 CET 2016 Do not use eready DLL data structure unless we are actually using epoll(). -DD/CG Fri Feb 5 20:43:11 CET 2016 Fixed testsuite compile warning on W32. Added check test for triggering poll() on listen socket. -EG Thu Feb 4 11:38:11 CET 2016 Added some buffer overrun protection.

Reworked and fixed code for using SOCK_CLOEXEC, SOCK_NONBLOCK and EPOLL_CLOEXEC resulting in fewer used system calls. -EG Tue Jan 19 20:59:59 CET 2016 Cleaned up and optimized with minor fixes code for making sockets non-blocking non-inheritable. -EG Tue Jan 19 11:14:18 CET 2016 Removed workaround for Cygwin non-blocking sockets: handling non-blocking sockets were fixed in Cygwin and libmicrohttpd how uses non-blocking sockets on all platforms. -EG Mon Jan 18 23:54:45 CET 2016 Cleaned up examples to avoid giving oversimplified code that may lead to complications if adopted naively. -CG Sun Jan 17 11:18:55 CET 2016 Do no refuse to send response if sendfile() failed with EINVAL (common error for files located on SMB/CIF). -EG Sat Jan 16 19:14:39 CET 2016 Use US-ASCII only (instead of user locale settings) when performing caseless string comparison as required by standard. -EG Tue Jan 12 16:10:09 CET 2016 Fixed declaraion of MHD_get_reason_phrase_for(). -EG Mon Jan 11 19:58:50 CET 2016 Configure.ac small fixes and refactoring. -EG Fri Dec 18 15:54:50 CET 2015 Releasing libmicrohttpd 0.9.48. -CG Tue Dec 15 18:35:55 CET 2015 Improved compatibility with VS2010 and other older compilers. -EG Tue Dec 8 21:48:44 CET 2015 Default backlog size for listen socket was changed from 32 to SOMAXCONN, added new option MHD_OPTION_LISTEN_BACKLOG_SIZE to override default backlog size. If not all connections can be handled by MHD_select() than at least some of connections will be processed instead of failing without any processing. Fixed redefenition of FD_SETSIZE on W32 so select() will work with 2000 connections instead of 64. Better handled redefenition of FD_SETSIZE on all platforms. -EG Sat Dec 5 17:30:45 CET 2015 Close sockets more aggressively in multi-threaded mode (possibly relevant for idle servers). -CG Fri Dec 4 13:53:05 CET 2015 Releasing libmicrohttpd 0.9.47. -CG Thu Dec 3 18:21:44 CET 2015 Reworked VS project files.

Thanks to Kenneth Mastro for reporting. -CG Sun Jun 22 12:22:08 CEST 2014 Actually, avoid locking on response as responses must not be modified in a connection-specific way; instead modify the connection's data buffer to add missing responses headers. If we are forced to add "Connection: close", suppress output of conflicting application-provided "Connection: Keep-Alive" header. -CG Sun Jun 22 00:22:08 CEST 2014 Lock on response if adding headers, needed if response object is shared across threads and connections. -CG Thu Jun 19 17:32:32 CEST 2014 Ensure that listen FD is bound to epoll FD even before MHD_run() is called if running with MHD_USE_EPOLL_LINUX_ONLY in combination with 'external select' mode.

Add flag to force HTTP 1.0-only conservative behavior, in particular suppressing adding "Connection" headers. -CG Mon Jun 2 00:03:28 CEST 2014 Added back unescaping for URI path (#3413) but without unescaping '+' (#3371) to remain compatible with MHD 0.9.34 and before. Note that applications providing a custom MHD_OPTION_UNESCAPE_CALLBACK are no longer expected to replace '+' with ' ', as that is now done separately for the locations where this transformation is appropriate.

Added --with-threads=LIB configure parameter. -EG Mon Apr 7 13:25:30 CEST 2014 Add MHD_OPTION_HTTPS_MEM_DHPARAMS to allow applications to enable PFS. -HB/CG Tue Apr 01 07:10:23 CET 2014 Added usage of native mutex on W32. -EG Sat Mar 29 16:12:03 CET 2014 Added MHD_is_feature_supported() function. -EG Thu Mar 27 14:47:54 CET 2014 Used larger FD_SETSIZE internally on W32.

Implemented FD_SETSIZE checks for W32. -EG Wed Mar 05 13:15:05 CET 2014 Cleanup and refactoring of configure.ac. m4 macros updated. Custom configure macros replaced with autoconf archive macros. SPDY disabled by default on W32. Changed configure flag from '--disable-pipe' to '--enable-socketpair'. Added configure flags '--disable-doc' and '--disable-examples'. Narrowed down external lib specific compiler and linker flags usage. -EG Wed Feb 26 17:42:34 CET 2014 Refactoring of configure.ac: custom macros replaced with macros from Autoconf Archive. Minor corrections of configure.ac. Excluded pthread flags from global flags, pthread now used only where required. W32: fixed .dll resource compilation with '-isystem' CPPFLAG. W32: improved header compatibility with MSVC. W32: now tested on Win64, compiled by MinGW-w64. -EG Mon Feb 24 23:13:53 CET 2014 Added support for TCP FASTOPEN. -SHT Releasing 0.9.34. -CG Thu Feb 20 14:17:05 CET 2014 W32: Added creation of libmicrohttpd.lib, libmicrohttpd.def, libmicrohttpd.exp and libmicrohttpd-static.lib for easy use compiled MHD with MSVC. W32: Use MS lib.exe tool if available for creating MSVC staff. W32: Added .dll information resource. -EG Tue Feb 18 19:46:45 CET 2014 Removed dependency on plibc for simpler compilation for W32. Added configure option "--disable-pipes" to use socketpairs instead of pipes for signalling to child threads. Pipes are always disabled on W32. Some code refactoring. -EG Sat Feb 8 15:08:35 CET 2014 Corrected some uses of 'int' vs. 'size_t'. -EG/CG Wed Jan 22 09:44:33 CET 2014 MHD_USE_DUAL_STACK in libmicrohttpd currently just *inhibits setting* the IPV6_V6ONLY socket option, but per Microsoft's documentation the default on Windows is that this is enabled, thus MHD_USE_DUAL_STACK will not work (since it leaves the default). libmicrohttpd should probably just unconditionally set IPV6_V6ONLY to the desired value when the option is available. -LJ Wed Jan 1 21:38:18 CET 2014 Allow Keep-Alive with HTTP 1.0 (if explicitly requested), and automatically set "Connection: Keep-Alive" in response in this case as well. -CG Tue Dec 24 12:27:39 CET 2013 Adding explicit annotations to hide symbols that are not for export in the C code (gcc 4.0 or higher only). -CG Sun Dec 22 14:54:30 CET 2013 Adding a few lines to avoid warnings from picky compilers. -CG Sat Dec 21 17:26:08 CET 2013 Fixed an issue with a missing argument in the postexample. Fixed issue with bogus offset increment involving sendfile on GNU/Linux. Adding support for SNI. Releasing 0.9.33. -CG Mon Dec 9 21:41:57 CET 2013 Fix for per-worker daemon pipes enabled with MHD_USE_SUSPEND_RESUME that were not closed in MHD_stop_daemon. -MH Sat Dec 7 00:44:49 CET 2013 Fixing warnings and build issue if --disable-https is given to configure. -CG Tue Dec 3 21:25:56 CET 2013 Security fix: do not read past 0-terminator when unescaping strings (thanks to Florian Weimer for reporting). Releasing 0.9.32. -CG Tue Dec 3 21:05:38 CET 2013 Signaling n times for shutdown works, but for resume we need to wake up the correct daemon. Even if we signal n times in that case also, there's no guarantee that some daemon can't run through its select loop more than once before the daemon we want to wake up gets a chance to read. Thus we need a signal pipe per thread in the thread pool IF MHD_suspend_connection is used. This introduces a new flag MHD_USE_SUSPEND_RESUME to add those additional pipes and only allow MHD_suspend_connection to be used in conjunction with this flag. Also, as MHD_resume_connection() will be called on a non-daemon thread, but none of the queue insert/delete calls are thread safe, we need to be concerned about (a) corrupting the queue, and (b) having to add mutex protection around every access to the queues, including loops through timer queues, etc. This wasn't a problem before adding resume; even suspend should be safe since it happens in a callback from the daemon. I think it's easier to (a) have MHD_suspend_connection() move the connection to a suspended queue, (b) have MHD_resume_connection() mark the connection as resuming, and then (c) do all the actual queue manipulations in MHD_select (poll, epoll, etc.) to move the resumed connections back to their normal queues, in response to the wake up. The changes are simpler & cleaner. There is a cost to the basic select loop that is avoided by making suspend/resume a startup option. The per-worker pipes can then also be enabled only with that option set. -MH Fri Nov 29 20:17:03 CET 2013 Eliminating theoretical stack overflow by limiting length of URIs in authentication headers to 32k (only applicable if the application explicitly raised the memory limits, and only applies to MHD_digest_auth_check). Issue was reported by Florian Weimer. -CG Tue Nov 26 01:26:15 CET 2013 Fix race on shutdown signal with thread pool on non-Linux systems by signalling n times for n threads. -CG Sun Nov 24 13:41:15 CET 2013 Introduce state to mark connections in suspended state (with epoll); add missing locking operations in MHD_suspend_connection. Fix definition of MHD_TLS_CONNECTION_INIT. -MH/JC Wed Oct 30 09:34:20 CET 2013 Fixing issue in PostProcessor when getting partial boundary at the beginning, expanding test suite. -CG Sun Oct 27 15:19:44 CET 2013 Implementing faster processing of upload data in multipart encoding (thanks to performance analysis by Adam Homolya). -CG Thu Oct 24 10:40:03 CEST 2013 Adding support for connection flow control via MHD_suspend_connection and MHD_resume_connection. -CG Sat Oct 19 16:40:32 CEST 2013 Releasing libmicrohttpd 0.9.31. -CG Mon Sep 23 20:24:48 CEST 2013 Fixing build issues on OS X with CLOCK_MONOTONIC not being implemented on OS X. -CG Mon Sep 23 14:15:00 CEST 2013 Make libmicrohttpd play nicely with upcoming libgcrypt 1.6.0. -CG Fri Sep 20 17:01:37 CEST 2013 Improved configure checks for cURL. -CG Wed Sep 18 18:29:24 CEST 2013 Signal connection termination as OK (and not as ERROR) if the stream was terminated by the callback returning MHD_CONTENT_READER_END_OF_STREAM. Also, release response mutex before calling the termination callback, to avoid possible deadlock if the client destroys the response in the termination callback (due to non-recursiveness of the lock). -CG Wed Sep 18 14:31:35 CEST 2013 Adding #define MHD_HTTP_HEADER_ACCESS_CONTROL_ALLOW_ORIGIN. -CG Tue Sep 17 21:32:47 CEST 2013 Also pass MHD connection handle in URI log callback. -CG Fri Sep 6 10:00:44 CEST 2013 Improved check for proper OpenSSL version for libmicrospdy. -CG Wed Sep 4 17:23:15 CEST 2013 Set IPV6_V6ONLY socket option correctly when IPv6 is enabled (MHD_USE_IPv6) but not dual stack (MHD_USE_DUAL_STACK) -MW Mon Sep 2 22:59:45 CEST 2013 Fix use-after-free in epoll()-mode on read error.

Note that for unsuccessful "CONNECT" requests with an empty response body, users must now explicitly set the content-length header. -CG Sun Jul 28 16:35:17 CEST 2013 Fixing build issue (missing #ifdef) in conjunction with --disable-messages. -blueness Sat Jul 20 12:35:40 CEST 2013 Fixing combination of MHD_USE_SSL and MHD_USE_EPOLL_LINUX_ONLY. -CG Fri Jul 19 09:57:27 CEST 2013 Fix issue where connections were not cleaned up when 'MHD_run_from_select' was used. Adding experimental TURBO mode. Releasing libmicrohttpd 0.9.28. -CG Sun Jul 14 19:57:56 CEST 2013 Removing 'shutdown' calls that happen just before close or that are for read-only and for a client that has already stopped sending anyway (thus reducing number of system calls slightly). -CG Sun Jul 14 19:37:37 CEST 2013 Name MHD worker threads on glibc >= 2.12. -,L4X[o](B Fri Jul 5 12:05:01 CEST 2013 Added MHD_OPTION_CONNECTION_MEMORY_INCREMENT to allow users to specify a custom value for incrementing read buffer sizes (#2899). -MH Fri Jun 28 14:05:15 CEST 2013 If we shutdown connection for reading on POST due to error, really do not process further requests even if we already read the next request from the connection. Furthermore, do not shutdown connections for reading on GET/HEAD/etc. just because the application queued a response immediately --- reserve that behavior for PUT/POST. -CG Tue Jun 25 15:08:30 CEST 2013 Added option 'MHD_USE_DUAL_STACK' to support a single daemon for IPv4 and IPv6 without the application having to do the binding. -CG Mon Jun 24 22:33:34 CEST 2013 Finished integration with epoll, including benchmarking and documentation. -CG Sun Jun 23 15:28:13 CEST 2013 Added option 'MHD_USE_PIPE_FOR_SHUTDOWN' to cleanly support 'MHD_quiesce_daemon' with thread pools and per-connection threads (we then need a pipe for shutdown, but if 'MHD_quiesce_daemon' is not used, we do not want to require the use of a pipe; introducing the pipe after the threads have been started can also fail, so the application needs to tell us early on). -CG Sat Jun 22 20:24:17 CEST 2013 Removed locking calls for thread modes that do not need them. Reorganized way to obtain connection's event loop state. Added sorted XDLL for connections with default timeout to avoid having to loop over all connections to determine current timeout (custom per-connection timeouts are in another list which is iterated each time). -CG Fri Jun 21 20:55:48 CEST 2013 Preparing build system and tests for epoll support. -CG Tue May 21 14:34:36 CEST 2013 Improving configure tests for OpenSSL and spdylay to avoid build errors in libmicrospdy code if those libraries are not present. -CG Mon May 20 12:29:35 CEST 2013 Added MHD_CONNECTION_INFO_CONNECTION_FD to allow clients direct access to connection socket; useful for COMET applications that need to disable NAGLE (#2886). -CG Mon May 15 12:49:01 CEST 2013 Fixing #2859. -CG Sun May 5 21:44:08 CEST 2013 Merged libmicrospdy code with libmicrohttpd build system (no major changes to libmicrospdy itself yet). -CG Sun May 5 20:13:59 CEST 2013 Improved documentation and code style a bit. Releasing libmicrohttpd 0.9.27. -CG Thu Apr 25 13:08:10 CEST 2013 Added 'MHD_quiesce_daemon' to allow application to stop processing new incoming connections while finishing ongoing requests. -CG Sun Mar 31 23:17:13 CEST 2013 Added MHD demonstration code 'src/examples/demo.c'. -CG Sun Mar 31 20:27:48 CEST 2013 Adding new API call 'MHD_run_from_select' to allow programs running in 'external select mode' to reduce the number of 'select' calls by a factor of two. -CG Sun Mar 31 20:03:48 CEST 2013 Performance improvements, updated documentation. Make better use of available memory pool memory for reading (especially important for large POST uploads); improve post processor speed by internally adjusting the buffer size by 4 bytes to ensure "round" IO sizes given a "round" post processor buffer size argument. Note that applications that previously added 4 bytes to the post processor buffer size might now perform worse. Using the new 'demo' example, POST upload speed increased from ~90 MB/s to ~120 MB/s for a large file (note that the improvement comes from better aligned disk IO; without disk IO, the speed was (and remains) at ~1500 MB/s on this system). -CG Fri Mar 29 16:44:29 CET 2013 Renaming testcases to consistently begin with test_; Changing build system to build examples in doc/.

(see mailinglist). -CG/MV Tue Jan 29 21:27:56 CET 2013 Make code work with PlibC 0.1.7 (which removed plibc_init_utf8). Only relevant for W32.

(See discussion on mailinglist). Also, if there is already a transfer-encoding other than 'chunked' set by the application, we also now close the connection if the response is of unknown size. -CG Wed Dec 5 19:22:26 CET 2012 Fixing parameter loss of POST parameters with IE8 and Chrome in the PostProcessor as the code failed to properly handle partial data. -MM Fri Nov 9 21:36:46 CET 2012 Releasing libmicrohttpd 0.9.23. -CG Thu Nov 8 22:32:59 CET 2012 Ship our own version of tsearch and friends if not provided by platform, so that MHD works nicely on Android. -JJ Mon Oct 22 13:05:01 CEST 2012 Immediately do a second read if we get a full buffer from TLS as there might be more data in the TLS buffers even if there is no activity on the socket. -CG Tue Oct 16 01:33:55 CEST 2012 Consistently use "#ifdef" and "#ifndef" WINDOWS, and not sometimes "#if". -CG Sat Sep 1 20:51:21 CEST 2012 Releasing libmicrohttpd 0.9.22. -CG Sat Sep 1 20:38:35 CEST 2012 Adding configure option to allow selecting support for basic and digest authentication separately (#2525). -CG Thu Aug 30 21:12:56 CEST 2012 Fixing URI argument parsing when string contained keys without equals sign (i.e. '&bar&') in the middle of the argument (#2531). Also replacing 'strstr' with more efficient 'strchr' when possible. -CG Tue Aug 21 14:36:17 CEST 2012 Use "int" instead of "enum X" in 'va_arg' calls to be nice to compilers that use 'short' (i.e. 8 or 16 bit) enums but pass enums still as "int" in varargs. (See discussion on mailinglist). -CG/MV Tue Aug 21 14:31:54 CEST 2012 Reduce default size in post processor buffer (for small systems; performance impact on large systems should be minimal). -CG/MV Thu Jul 19 21:48:42 CEST 2012 Releasing libmicrohttpd 0.9.21. -CG Thu Jul 19 11:34:50 CEST 2012 Consistently use 'panic' function instead of ever directly calling 'abort ()'.

Sun Sep 28 14:57:46 MDT 2008 Unescape URIs (convert "%ef%e4%45" to "$BCf9q(B"). -CG Wed Sep 10 22:43:59 MDT 2008 Releasing GNU libmicrohttpd 0.4.0pre0. -CG Wed Sep 10 21:36:06 MDT 2008 Fixed data race on closing sockets during shutdown (in one-thread-per-connection mode). -CG Thu Sep 4 23:37:18 MDT 2008 Fixed some boundary issues with processing chunked requests; removed memmove from a number of spots, in favor of using an index into the current buffer instead. -GS Sun Aug 24 13:05:41 MDT 2008 Now handling clients returning 0 from response callback as specified in the documentation (abort if internal select is used, retry immediately if a thread per connection is used). -CG Sun Aug 24 12:44:43 MDT 2008 Added missing reason phrase. -SG Sun Aug 24 10:33:22 MDT 2008 Fixed bug where MHD failed to transmit the response when the client decided not to send "100 CONTINUE" during a PUT/POST request. -CG Wed Jul 16 18:54:03 MDT 2008 Fixed bug generating chunked responses with chunk sizes greater than 0xFFFFFF (would cause protocol violations). -CG Mon May 26 13:28:57 MDT 2008 Updated and improved documentation. Releasing GNU libmicrohttpd 0.3.1. -CG Fri May 23 16:54:41 MDT 2008 Fixed issue with postprocessor not handling URI-encoded values of more than 1024 bytes correctly. -CG Mon May 5 09:18:29 MDT 2008 Fixed date header (was off by 1900 years). -JP Sun Apr 13 01:06:20 MDT 2008 Releasing GNU libmicrohttpd 0.3.0. -CG Sat Apr 12 21:34:26 MDT 2008 Generate an internal server error if the programmer fails to handle upload data correctly. Tweaked testcases to avoid running into the problem in the testcases. Completed zzuf-based fuzzing testcases. -CG Sat Apr 12 15:14:05 MDT 2008 Restructured the code (curl-testcases and zzuf testcases are now in different directories; code examples are in src/examples/). Fixed a problem (introduced in 0.2.3) with handling very large requests (the code did not return proper error code). If "--enable-messages" is specified, the code now includes reasonable default HTML webpages for various built-in errors (such as request too large and malformed requests). Without that flag, the webpages returned will still be empty. Started to add zzuf-based fuzzing-testcases (these require the zzuf and socat binaries to be installed). -CG Fri Apr 11 20:20:34 MDT 2008 I hereby dub libmicrohttpd a GNU package. -Richard Stallman Sat Mar 29 22:36:09 MDT 2008 Fixed bugs in handling of malformed HTTP requests (causing either NULL dereferences or connections to persist until time-out, if any). -CG Updated and integrated TexInfo documentation. -CG Tue Mar 25 13:40:53 MDT 2008 Prevent multi-part post-processor from going to error state when the input buffer is full and current token just changes processor state without consuming any data. Also, the original implementation would not consume any input in process_value_to_boundary if there is no new line character in sight. -AS Remove checks for request method after it finished writing response footers as it's only _pipelined_ requests that should not be allowed after POST or PUT requests. Reusing the existing connection is perfectly ok though. And there is no reliable way to detect pipelining on server side anyway so it is the client's responsibility to not send new data before it gets a response after a POST operation. -AS Clarified license in man page. Releasing libmicrohttpd 0.2.3 -CG Sat Mar 22 01:12:38 MDT 2008 Releasing libmicrohttpd 0.2.2. -CG Mon Feb 25 19:13:53 MST 2008 Fixed a problem with sockets closed for reading ending up in the read set under certain circumstances. -CG Wed Jan 30 23:15:44 MST 2008 Added support for nested multiparts to post processor. Made sure that MHD does not allow pipelining for methods other than HEAD and GET (and of course still also only allows it for http 1.1). Releasing libmicrohttpd 0.2.1. -CG Mon Jan 21 11:59:46 MST 2008 Added option to limit number of concurrent connections accepted from the same IP address. -CG Fri Jan 4 16:02:08 MST 2008 Fix to properly close connection if application signals problem handling the request. - AS Wed Jan 2 16:41:05 MST 2008 Improvements and bugfixes to post processor implementation. - AS Wed Dec 19 21:12:04 MST 2007 Implemented chunked (HTTP 1.1) downloads (including sending of HTTP footers). Also allowed queuing of a response early to suppress the otherwise automatic "100 CONTINUE" response. Removed the mostly useless "(un)register handler" methods from the API. Changed the internal implementation to use a finite state machine (cleaner code, slightly less memory consumption). Releasing libmicrohttpd 0.2.0. - CG Sun Dec 16 03:24:13 MST 2007 Implemented handling of chunked (HTTP 1.1) uploads. Note that the upload callback must be able to process chunks in the size uploaded by the client, MHD will not "join" small chunks into a big contiguous block of memory (even if buffer space would be available). - CG Wed Dec 5 21:39:35 MST 2007 Fixed race in multi-threaded server mode. Fixed handling of POST data when receiving a "Connection: close" header (#1296). Releasing libmicrohttpd 0.1.2. - CG Sat Nov 17 00:55:24 MST 2007 Fixed off-by-one in error message string matching. Added code to avoid generating SIGPIPE on platforms where this is possible (everywhere else, the main application should install a handler for SIGPIPE). Thu Oct 11 11:02:06 MDT 2007 Releasing libmicrohttpd 0.1.1. - CG Thu Oct 11 10:09:12 MDT 2007 Fixing response to include HTTP status message. - EG Thu Sep 27 10:19:46 MDT 2007 Fixing parsing of "%xx" in URLs with GET arguments. - eglaysher Sun Sep 9 14:32:23 MDT 2007 Added option to compile debug/warning messages; error messages are now disabled by default. Modified linker option for GNU LD to not export non-public symbols (further reduces binary size). Releasing libmicrohttpd 0.1.0. - CG Sat Sep 8 21:54:04 MDT 2007 Extended API to allow for incremental POST processing. The new API is binary-compatible as long as the app does not handle POSTs, but since that maybe the case, we're strictly speaking breaking backwards compatibility (since url-encoded POST data is no longer obtained the same way). - CG Thu Aug 30 00:59:24 MDT 2007 Improving API to allow clients to associate state with a connection and to be notified about request termination (this is a binary-compatible change). - CG Fixed compile errors under OS X. - HL Sun Aug 26 03:11:46 MDT 2007 Added MHD_USE_PEDANTIC_CHECKS option which enforces receiving a "Host:" header in HTTP 1.1 (and sends a HTTP 400 status back if this is violated). - CG Tue Aug 21 01:01:46 MDT 2007 Fixing assertion failure that occurred when a client closed the connection after sending some data but not the full headers. - CG Sat Aug 18 03:06:09 MDT 2007 Check for out of memory when adding headers to responses. Check for NULL key when looking for headers. If a content reader callback for a response returns zero (has no data yet), do not possibly fall into busy waiting when using external select (with internal selects we have no choice). - CG Wed Aug 15 01:46:44 MDT 2007 Extending API to allow timeout of connections. Changed API (MHD_create_response_from_callback) to allow user to specify IO buffer size. Improved error handling. Released libmicrohttpd 0.0.3. - CG Tue Aug 14 19:45:49 MDT 2007 Changed license to LGPL (with consent from all contributors). Released libmicrohttpd 0.0.2. - CG Sun Aug 12 00:09:26 MDT 2007 Released libmicrohttpd 0.0.1. - CG Fri Aug 10 17:31:23 MDT 2007 Fixed problems with handling of responses created from callbacks. Allowing accept policy callback to be NULL (to accept from all). Added minimal fileserver example. Only send 100 continue header when specifically requested. - CG Wed Aug 8 01:46:06 MDT 2007 Added pool allocation and connection limitations (total number and memory size). Released libmicrohttpd 0.0.0. - CG Tue Jan 9 20:52:48 MST 2007 Created project build files and updated API. - CG libmicrohttpd-1.0.1/libmicrohttpd.pc.in0000644000175000017500000000051114417460232013633 prefix=@prefix@ exec_prefix=@exec_prefix@ libdir=@libdir@ includedir=@includedir@ Name: libmicrohttpd Description: A library for creating an embedded HTTP server Version: @VERSION@ Requires: Requires.private: @MHD_REQ_PRIVATE@ Conflicts: Libs: -L${libdir} -lmicrohttpd Libs.private: @MHD_LIBDEPS_PKGCFG@ Cflags: -I${includedir} libmicrohttpd-1.0.1/COPYING0000644000175000017500000006013114417460232011075 Some of this code is DUAL-LICENSED.

GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

File: libmicrohttpd.info, Node: microhttpd-intro, Next: microhttpd-const, Prev: Top, Up: Top 1 Introduction ************** All symbols defined in the public API start with ‘MHD_’. MHD is a small HTTP daemon library. As such, it does not have any API for logging errors (you can only enable or disable logging to stderr). Also, it may not support all of the HTTP features directly, where applicable, portions of HTTP may have to be handled by clients of the library. The library is supposed to handle everything that it must handle (because the API would not allow clients to do this), such as basic connection management. However, detailed interpretations of headers, such as range requests, are left to the main application. In particular, if an application developer wants to support range requests, he needs to explicitly indicate support in responses and also explicitly parse the range header and generate a response (for example, using the ‘MHD_create_response_from_fd_at_offset’ call to serve ranges from a file). MHD does understands headers that control connection management (specifically, ‘Connection: close’ and ‘Expect: 100 continue’ are understood and handled automatically). ‘Connection: upgrade’ is supported by passing control over the socket (or something that behaves like the real socket in the case of TLS) to the application (after sending the desired HTTP response header). MHD largely ignores the semantics of the different HTTP methods, so clients are left to handle those. One exception is that MHD does understand ‘HEAD’ and will only send the headers of the response and not the body, even if the client supplied a body. (In fact, clients do need to construct a response with the correct length, even for ‘HEAD’ request.) MHD understands ‘POST’ data and is able to decode certain formats (at the moment only ‘application/x-www-form-urlencoded’ and ‘multipart/form-data’) using the post processor API. The data stream of a POST is also provided directly to the main application, so unsupported encodings could still be processed, just not conveniently by MHD. The header file defines various constants used by the HTTP protocol. This does not mean that MHD actually interprets all of these values. The provided constants are exported as a convenience for users of the library. MHD does not verify that transmitted HTTP headers are part of the standard specification; users of the library are free to define their own extensions of the HTTP standard and use those with MHD. All functions are guaranteed to be completely reentrant and thread-safe. MHD checks for allocation failures and tries to recover gracefully (for example, by closing the connection). Additionally, clients can specify resource limits on the overall number of connections, number of connections per IP address and memory used per connection to avoid resource exhaustion. 1.1 Scope ========= MHD is currently used in a wide range of implementations. Examples based on reports we've received from developers include: • Embedded HTTP server on a cortex M3 (128 KB code space) • Large-scale multimedia server (reportedly serving at the simulator limit of 7.5 GB/s) • Administrative console (via HTTP/HTTPS) for network appliances 1.2 Thread modes and event loops ================================ MHD supports four basic thread modes and up to three event loop styles. The four basic thread modes are external sockets polling (MHD creates no threads, event loop is fully managed by the application), internal polling (MHD creates one thread for all connections), polling in thread pool (MHD creates a thread pool which is used to process all connections) and thread-per-connection (MHD creates one thread for listen sockets and then one thread per accepted connection). These thread modes are then combined with the evet loop styles (polling function type). MHD support select, poll and epoll. select is available on all platforms, epoll and poll may not be available on some platforms. Note that it is possible to combine MHD using epoll with an external select-based event loop. The default (if no other option is passed) is "external select". The highest performance can typically be obtained with a thread pool using ‘epoll’. Apache Benchmark (ab) was used to compare the performance of ‘select’ and ‘epoll’ when using a thread pool and a large number of connections. *note Figure 1.1: fig:performance. shows the resulting plot from the ‘benchmark.c’ example, which measures the latency between an incoming request and the completion of the transmission of the response. In this setting, the ‘epoll’ thread pool with four threads was able to handle more than 45,000 connections per second on loopback (with Apache Benchmark running three processes on the same machine). [image src="libmicrohttpd_performance_data.png" alt="Data"] Figure 1.1: Performance measurements for select vs. epoll (with thread-pool). Not all combinations of thread modes and event loop styles are supported. This is partially to keep the API simple, and partially because some combinations simply make no sense as others are strictly superior. Note that the choice of style depends first of all on the application logic, and then on the performance requirements. Applications that perform a blocking operation while handling a request within the callbacks from MHD must use a thread per connection. This is typically rather costly. Applications that do not support threads or that must run on embedded devices without thread-support must use the external mode. Using ‘epoll’ is only supported on some platform, thus portable applications must at least have a fallback option available. *note Table 1.1: tbl:supported. lists the sane combinations. select poll epoll external yes no yes internal yes yes yes thread pool yes yes yes thread-per-connection yes yes no Table 1.1: Supported combinations of event styles and thread modes. 1.3 Compiling GNU libmicrohttpd =============================== MHD uses the standard GNU system where the usual build process involves running $ ./configure $ make $ make install MHD supports various options to be given to configure to tailor the binary to a specific situation. Note that some of these options will remove portions of the MHD code that are required for binary-compatibility. They should only be used on embedded systems with tight resource constraints and no concerns about library versioning. Standard distributions including MHD are expected to always ship with all features enabled, otherwise unexpected incompatibilities can arise! Here is a list of MHD-specific options that can be given to configure (canonical configure options such as "-prefix" are also supported, for a full list of options run "./configure -help"): ‘``--disable-curl''’ disable running testcases using libcurl ‘``--disable-largefile''’ disable support for 64-bit files ‘``--disable-messages''’ disable logging of error messages (smaller binary size, not so much fun for debugging) ‘``--disable-https''’ disable HTTPS support, even if GNUtls is found; this option must be used if eCOS license is desired as an option (in all cases the resulting binary falls under a GNU LGPL-only license) ‘``--disable-postprocessor''’ do not include the post processor API (results in binary incompatibility) ‘``--disable-dauth''’ do not include the authentication APIs (results in binary incompatibility) ‘``--disable-httpupgrade''’ do not build code for HTTP "Upgrade" (smaller binary size, binary incompatible library) ‘``--disable-epoll''’ do not include epoll support, even if it supported (minimally smaller binary size, good for portability testing) ‘``--enable-coverage''’ set flags for analysis of code-coverage with gcc/gcov (results in slow, large binaries) ‘``--with-threads=posix,w32,none,auto''’ sets threading library to use. With use "none" to not support threads. In this case, MHD will only support the "external" threading modes and not perform any locking of data structures! Use ‘MHD_is_feature_supported(MHD_FEATURE_THREADS)’ to test if threads are available. Default is "auto". ‘``--with-gcrypt=PATH''’ specifies path to libgcrypt installation ‘``--with-gnutls=PATH''’ specifies path to libgnutls installation To cross-compile MHD for Android, install the Android NDK and use: ./configure --target=arm-linux-androideabi --host=arm-linux-androideabi --disable-doc --disable-examples make Similar build commands should work for cross-compilation to other platforms. Note that you may have to first cross-compile GnuTLS to get MHD with TLS support. 1.4 Validity of pointers ======================== MHD will give applications access to its internal data structures via pointers via arguments and return values from its API. This creates the question as to how long those pointers are assured to stay valid. Most MHD data structures are associated with the connection of an HTTP client. Thus, pointers associated with a connection are typically valid until the connection is finished, at which point MHD will call the ‘MHD_RequestCompletedCallback’ if one is registered. Applications that have such a callback registered may assume that keys and values from the ‘MHD_KeyValueIterator’, return values from ‘MHD_lookup_connection_value’ and the ‘url’, ‘method’ and ‘version’ arguments to the ‘MHD_AccessHandlerCallback’ will remain valid until the respective ‘MHD_RequestCompletedCallback’ is invoked. In contrast, the ‘upload_data’ argument of ‘MHD_RequestCompletedCallback’ as well as all pointers from the ‘MHD_PostDataIterator’ are only valid for the duration of the callback. Pointers returned from ‘MHD_get_response_header’ are valid as long as the response itself is valid. 1.5 Including the microhttpd.h header ===================================== Ideally, before including "microhttpd.h" you should add the necessary includes to define the ‘va_list’, ‘size_t’, ‘ssize_t’, ‘intptr_t’, ‘off_t’, ‘uint8_t’, ‘uint16_t’, ‘int32_t’, ‘uint32_t’, ‘int64_t’, ‘uint64_t’, ‘fd_set’, ‘socklen_t’ and ‘struct sockaddr’ data types. Which specific headers are needed may depend on your platform and your build system might include some tests to provide you with the necessary conditional operations. For possible suggestions consult ‘platform.h’ and ‘configure.ac’ in the MHD distribution. Once you have ensured that you manually (!) included the right headers for your platform before "microhttpd.h", you should also add a line with ‘#define MHD_PLATFORM_H’ which will prevent the "microhttpd.h" header from trying (and, depending on your platform, failing) to include the right headers. If you do not define MHD_PLATFORM_H, the "microhttpd.h" header will automatically include headers needed on GNU/Linux systems (possibly causing problems when porting to other platforms). 1.6 SIGPIPE =========== MHD does not install a signal handler for SIGPIPE. On platforms where this is possible (such as GNU/Linux), it disables SIGPIPE for its I/O operations (by passing MSG_NOSIGNAL or similar). On other platforms, SIGPIPE signals may be generated from network operations by MHD and will cause the process to die unless the developer explicitly installs a signal handler for SIGPIPE. Hence portable code using MHD must install a SIGPIPE handler or explicitly block the SIGPIPE signal. MHD does not do so in order to avoid messing with other parts of the application that may need to handle SIGPIPE in a particular way. You can make your application handle SIGPIPE by calling the following function in ‘main’: static void catcher (int sig) { } static void ignore_sigpipe () { struct sigaction oldsig; struct sigaction sig; sig.sa_handler = &catcher; sigemptyset (&sig.sa_mask); #ifdef SA_INTERRUPT sig.sa_flags = SA_INTERRUPT; /* SunOS */ #else sig.sa_flags = SA_RESTART; #endif if (0 != sigaction (SIGPIPE, &sig, &oldsig)) fprintf (stderr, "Failed to install SIGPIPE handler: %s\n", strerror (errno)); } 1.7 MHD_UNSIGNED_LONG_LONG ========================== Some platforms do not support ‘long long’. Hence MHD defines a macro ‘MHD_UNSIGNED LONG_LONG’ which will default to ‘unsigned long long’. For standard desktop operating systems, this is all you need to know. However, if your platform does not support ‘unsigned long long’, you should change "platform.h" to define ‘MHD_LONG_LONG’ and ‘MHD_UNSIGNED_LONG_LONG’ to an appropriate alternative type and also define ‘MHD_LONG_LONG_PRINTF’ and ‘MHD_UNSIGNED_LONG_LONG_PRINTF’ to the corresponding format string for printing such a data type. Note that the "signed" versions are deprecated. Also, for historical reasons, ‘MHD_LONG_LONG_PRINTF’ is without the percent sign, whereas ‘MHD_UNSIGNED_LONG_LONG_PRINTF’ is with the percent sign. Newly written code should only use the unsigned versions. However, you need to define both in "platform.h" if you need to change the definition for the specific platform. 1.8 Portability to W32 ====================== libmicrohttpd in general ported well to W32. Most libmicrohttpd features are supported. W32 do not support some functions, like epoll and corresponding MHD features are not available on W32. 1.9 Portability to z/OS ======================= To compile MHD on z/OS, extract the archive and run iconv -f UTF-8 -t IBM-1047 contrib/ascebc > /tmp/ascebc.sh chmod +x /tmp/ascebc.sh for n in `find * -type f` do /tmp/ascebc.sh $n done to convert all source files to EBCDIC. Note that you must run ‘configure’ from the directory where the configure script is located. Otherwise, configure will fail to find the ‘contrib/xcc’ script (which is a wrapper around the z/OS c89 compiler).  File: libmicrohttpd.info, Node: microhttpd-const, Next: microhttpd-struct, Prev: microhttpd-intro, Up: Top 2 Constants *********** -- Enumeration: MHD_FLAG Options for the MHD daemon. Note that MHD will run automatically in background thread(s) only if ‘MHD_USE_INTERNAL_POLLING_THREAD’ is used. Otherwise caller (application) must use ‘MHD_run’ or ‘MHD_run_from_select’ to have MHD processed network connections and data. Starting the daemon may also fail if a particular option is not implemented or not supported on the target platform (i.e. no support for TLS, threads or IPv6). TLS support generally depends on options given during MHD compilation. ‘MHD_NO_FLAG’ No options selected. ‘MHD_USE_ERROR_LOG’ If this flag is used, the library should print error messages and warnings to stderr (or to custom error printer if it's specified by options). Note that for this run-time option to have any effect, MHD needs to be compiled with messages enabled. This is done by default except you ran configure with the ‘--disable-messages’ flag set. ‘MHD_USE_DEBUG’ Currently the same as ‘MHD_USE_ERROR_LOG’. ‘MHD_USE_TLS’ Run in HTTPS-mode. If you specify ‘MHD_USE_TLS’ and MHD was compiled without SSL support, ‘MHD_start_daemon’ will return NULL. ‘MHD_USE_THREAD_PER_CONNECTION’ Run using one thread per connection. ‘MHD_USE_INTERNAL_POLLING_THREAD’ Run using an internal thread doing ‘SELECT’. ‘MHD_USE_IPv6’ Run using the IPv6 protocol (otherwise, MHD will just support IPv4). If you specify ‘MHD_USE_IPV6’ and the local platform does not support it, ‘MHD_start_daemon’ will return NULL. If you want MHD to support IPv4 and IPv6 using a single socket, pass MHD_USE_DUAL_STACK, otherwise, if you only pass this option, MHD will try to bind to IPv6-only (resulting in no IPv4 support). ‘MHD_USE_DUAL_STACK’ Use a single socket for IPv4 and IPv6. Note that this will mean that IPv4 addresses are returned by MHD in the IPv6-mapped format (the 'struct sockaddr_in6' format will be used for IPv4 and IPv6). ‘MHD_USE_PEDANTIC_CHECKS’ Deprecated (use ‘MHD_OPTION_STRICT_FOR_CLIENT’). Be pedantic about the protocol. Specifically, at the moment, this flag causes MHD to reject HTTP 1.1 connections without a ‘Host’ header. This is required by the standard, but of course in violation of the "be as liberal as possible in what you accept" norm. It is recommended to turn this *ON* if you are testing clients against MHD, and *OFF* in production. ‘MHD_USE_POLL’ Use ‘poll()’ instead of ‘select()’. This allows sockets with descriptors ‘>= FD_SETSIZE’. This option currently only works in conjunction with ‘MHD_USE_INTERNAL_POLLING_THREAD’ (at this point). If you specify ‘MHD_USE_POLL’ and the local platform does not support it, ‘MHD_start_daemon’ will return NULL. ‘MHD_USE_EPOLL’ Use ‘epoll()’ instead of ‘poll()’ or ‘select()’. This allows sockets with descriptors ‘>= FD_SETSIZE’. This option is only available on some systems and does not work in conjunction with ‘MHD_USE_THREAD_PER_CONNECTION’ (at this point). If you specify ‘MHD_USE_EPOLL’ and the local platform does not support it, ‘MHD_start_daemon’ will return NULL. Using ‘epoll()’ instead of ‘select()’ or ‘poll()’ can in some situations result in significantly higher performance as the system call has fundamentally lower complexity (O(1) for ‘epoll()’ vs. O(n) for ‘select()’/‘poll()’ where n is the number of open connections). ‘MHD_USE_TURBO’ Enable optimizations to aggressively improve performance. Currently, the optimizations this option enables are based on opportunistic reads and writes. Basically, MHD will simply try to read or write or accept on a socket before checking that the socket is ready for IO using the event loop mechanism. As the sockets are non-blocking, this may fail (at a loss of performance), but generally MHD does this in situations where the operation is likely to succeed, in which case performance is improved. Setting the flag should generally be safe (even though the code is slightly more experimental). You may want to benchmark your application to see if this makes any difference for you. ‘MHD_USE_SUPPRESS_DATE_NO_CLOCK’ Suppress (automatically) adding the 'Date:' header to HTTP responses. This option should ONLY be used on systems that do not have a clock and that DO provide other mechanisms for cache control. See also RFC 2616, section 14.18 (exception 3). ‘MHD_USE_NO_LISTEN_SOCKET’ Run the HTTP server without any listen socket. This option only makes sense if ‘MHD_add_connection’ is going to be used exclusively to connect HTTP clients to the HTTP server. This option is incompatible with using a thread pool; if it is used, ‘MHD_OPTION_THREAD_POOL_SIZE’ is ignored. ‘MHD_USE_ITC’ Force MHD to use a signal inter-thread communication channel to notify the event loop (of threads) of our shutdown and other events. This is required if an application uses ‘MHD_USE_INTERNAL_POLLING_THREAD’ and then performs ‘MHD_quiesce_daemon’ (which eliminates our ability to signal termination via the listen socket). In these modes, ‘MHD_quiesce_daemon’ will fail if this option was not set. Also, use of this option is automatic (as in, you do not even have to specify it), if ‘MHD_USE_NO_LISTEN_SOCKET’ is specified. In "external" select mode, this option is always simply ignored. Using this option also guarantees that MHD will not call ‘shutdown()’ on the listen socket, which means a parent process can continue to use the socket. ‘MHD_ALLOW_SUSPEND_RESUME’ Enables using ‘MHD_suspend_connection’ and ‘MHD_resume_connection’, as performing these calls requires some additional inter-thred communication channels to be created, and code not using these calls should not pay the cost. ‘MHD_USE_TCP_FASTOPEN’ Enable TCP_FASTOPEN on the listen socket. TCP_FASTOPEN is currently supported on Linux >= 3.6. On other systems using this option with cause ‘MHD_start_daemon’ to fail. ‘MHD_ALLOW_UPGRADE’ This option must be set if you want to upgrade connections (via "101 Switching Protocols" responses). This requires MHD to allocate additional resources, and hence we require this special flag so we only use the resources that are really needed. ‘MHD_USE_AUTO’ Automatically select best event loop style (polling function) depending on requested mode by other MHD flags and functions available on platform. If application doesn't have requirements for any specific polling function, it's recommended to use this flag. This flag is very convenient for multiplatform applications. ‘MHD_USE_POST_HANDSHAKE_AUTH_SUPPORT’ Tell the TLS library to support post handshake client authentication. Only useful in combination with ‘MHD_USE_TLS’. This option will only work if the underlying TLS library supports it (i.e. GnuTLS after 3.6.3). If the TLS library does not support it, MHD may ignore the option and proceed without supporting this features. ‘MHD_USE_INSECURE_TLS_EARLY_DATA’ Tell the TLS library to support TLS v1.3 early data (0-RTT) with the resulting security drawbacks. Only enable this if you really know what you are doing. MHD currently does NOT enforce that this only affects GET requests! You have been warned. This option will only work if the underlying TLS library supports it (i.e. GnuTLS after 3.6.3). If the TLS library does not support it, MHD may ignore the option and proceed without supporting this features. -- Enumeration: MHD_OPTION MHD options. Passed in the varargs portion of ‘MHD_start_daemon()’. ‘MHD_OPTION_END’ No more options / last option. This is used to terminate the VARARGs list. ‘MHD_OPTION_CONNECTION_MEMORY_LIMIT’ Maximum memory size per connection (followed by a ‘size_t’). The default is 32 kB (32*1024 bytes) as defined by the internal constant ‘MHD_POOL_SIZE_DEFAULT’. Values above 128k are unlikely to result in much benefit, as half of the memory will be typically used for IO, and TCP buffers are unlikely to support window sizes above 64k on most systems. ‘MHD_OPTION_CONNECTION_MEMORY_INCREMENT’ Increment to use for growing the read buffer (followed by a ‘size_t’). The default is 1024 (bytes). Increasing this value will make MHD use memory for reading more aggressively, which can reduce the number of ‘recvfrom’ calls but may increase the number of ‘sendto’ calls. The given value must fit within MHD_OPTION_CONNECTION_MEMORY_LIMIT. ‘MHD_OPTION_CONNECTION_LIMIT’ Maximum number of concurrent connections to accept (followed by an ‘unsigned int’). The default is ‘FD_SETSIZE - 4’ (the maximum number of file descriptors supported by ‘select’ minus four for ‘stdin’, ‘stdout’, ‘stderr’ and the server socket). In other words, the default is as large as possible. If the connection limit is reached, MHD's behavior depends a bit on other options. If ‘MHD_USE_ITC’ was given, MHD will stop accepting connections on the listen socket. This will cause the operating system to queue connections (up to the ‘listen()’ limit) above the connection limit. Those connections will be held until MHD is done processing at least one of the active connections. If ‘MHD_USE_ITC’ is not set, then MHD will continue to ‘accept()’ and immediately ‘close()’ these connections. Note that if you set a low connection limit, you can easily get into trouble with browsers doing request pipelining. For example, if your connection limit is "1", a browser may open a first connection to access your "index.html" file, keep it open but use a second connection to retrieve CSS files, images and the like. In fact, modern browsers are typically by default configured for up to 15 parallel connections to a single server. If this happens, MHD will refuse to even accept the second connection until the first connection is closed -- which does not happen until timeout. As a result, the browser will fail to render the page and seem to hang. If you expect your server to operate close to the connection limit, you should first consider using a lower timeout value and also possibly add a "Connection: close" header to your response to ensure that request pipelining is not used and connections are closed immediately after the request has completed: MHD_add_response_header (response, MHD_HTTP_HEADER_CONNECTION, "close"); ‘MHD_OPTION_CONNECTION_TIMEOUT’ After how many seconds of inactivity should a connection automatically be timed out? (followed by an ‘unsigned int’; use zero for no timeout). The default is zero (no timeout). ‘MHD_OPTION_NOTIFY_COMPLETED’ Register a function that should be called whenever a request has been completed (this can be used for application-specific clean up). Requests that have never been presented to the application (via ‘MHD_AccessHandlerCallback()’) will not result in notifications. This option should be followed by *TWO* pointers. First a pointer to a function of type ‘MHD_RequestCompletedCallback()’ and second a pointer to a closure to pass to the request completed callback. The second pointer maybe ‘NULL’. ‘MHD_OPTION_NOTIFY_CONNECTION’ Register a function that should be called when the TCP connection to a client is opened or closed. The registered callback is called twice per TCP connection, with ‘MHD_CONNECTION_NOTIFY_STARTED’ and ‘MHD_CONNECTION_NOTIFY_CLOSED’ respectively. An additional argument can be used to store TCP connection specific information, which can be retrieved using ‘MHD_CONNECTION_INFO_SOCKET_CONTEXT’ during the lifetime of the TCP connection. Note ‘MHD_OPTION_NOTIFY_COMPLETED’ and the ‘req_cls’ argument to the ‘MHD_AccessHandlerCallback’ are per HTTP request (and there can be multiple HTTP requests per TCP connection). This option should be followed by *TWO* pointers. First a pointer to a function of type ‘MHD_NotifyConnectionCallback()’ and second a pointer to a closure to pass to the request completed callback. The second pointer maybe ‘NULL’. ‘MHD_OPTION_PER_IP_CONNECTION_LIMIT’ Limit on the number of (concurrent) connections made to the server from the same IP address. Can be used to prevent one IP from taking over all of the allowed connections. If the same IP tries to establish more than the specified number of connections, they will be immediately rejected. The option should be followed by an ‘unsigned int’. The default is zero, which means no limit on the number of connections from the same IP address. ‘MHD_OPTION_LISTEN_BACKLOG_SIZE’ Set the size of the ‘listen()’ back log queue of the TCP socket. Takes an ‘unsigned int’ as the argument. Default is the platform-specific value of ‘SOMAXCONN’. ‘MHD_OPTION_STRICT_FOR_CLIENT’ Specify how strict we should enforce the HTTP protocol. Takes an ‘int’ as the argument. Default is zero. If set to 1, MHD will be strict about the protocol. Specifically, at the moment, this flag uses MHD to reject HTTP 1.1 connections without a "Host" header. This is required by the standard, but of course in violation of the "be as liberal as possible in what you accept" norm. It is recommended to set this to 1 if you are testing clients against MHD, and 0 in production. If set to -1 MHD will be permissive about the protocol, allowing slight deviations that are technically not allowed by the RFC. Specifically, at the moment, this flag causes MHD to allow spaces in header field names. This is disallowed by the standard. It is not recommended to set it to -1 on publicly available servers as it may potentially lower level of protection. ‘MHD_OPTION_SERVER_INSANITY’ Allows the application to disable certain sanity precautions in MHD. With these, the client can break the HTTP protocol, so this should never be used in production. The options are, however, useful for testing HTTP clients against "broken" server implementations. This argument must be followed by an ‘unsigned int’, corresponding to an ‘enum MHD_DisableSanityCheck’. Right now, no sanity checks can be disabled. ‘MHD_OPTION_SOCK_ADDR’ Bind daemon to the supplied socket address. This option should be followed by a ‘struct sockaddr *’. If ‘MHD_USE_IPv6’ is specified, the ‘struct sockaddr*’ should point to a ‘struct sockaddr_in6’, otherwise to a ‘struct sockaddr_in’. If this option is not specified, the daemon will listen to incoming connections from anywhere. If you use this option, the 'port' argument from ‘MHD_start_daemon’ is ignored and the port from the given ‘struct sockaddr *’ will be used instead. ‘MHD_OPTION_URI_LOG_CALLBACK’ Specify a function that should be called before parsing the URI from the client. The specified callback function can be used for processing the URI (including the options) before it is parsed. The URI after parsing will no longer contain the options, which maybe inconvenient for logging. This option should be followed by two arguments, the first one must be of the form void * my_logger(void * cls, const char * uri, struct MHD_Connection *con) where the return value will be passed as ‘*req_cls’ in calls to the ‘MHD_AccessHandlerCallback’ when this request is processed later; returning a value of ‘NULL’ has no special significance; (however, note that if you return non-‘NULL’, you can no longer rely on the first call to the access handler having ‘NULL == *req_cls’ on entry) ‘cls’ will be set to the second argument following MHD_OPTION_URI_LOG_CALLBACK. Finally, ‘uri’ will be the 0-terminated URI of the request. Note that during the time of this call, most of the connection's state is not initialized (as we have not yet parsed he headers). However, information about the connecting client (IP, socket) is available. ‘MHD_OPTION_HTTPS_MEM_KEY’ Memory pointer to the private key to be used by the HTTPS daemon. This option should be followed by an "const char*" argument. This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_CERT'. ‘MHD_OPTION_HTTPS_KEY_PASSWORD’ Memory pointer to the password that decrypts the private key to be used by the HTTPS daemon. This option should be followed by an "const char*" argument. This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_KEY'. The password (or passphrase) is only used immediately during ‘MHD_start_daemon()’. Thus, the application may want to erase it from memory afterwards for additional security. ‘MHD_OPTION_HTTPS_MEM_CERT’ Memory pointer to the certificate to be used by the HTTPS daemon. This option should be followed by an "const char*" argument. This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_KEY'. ‘MHD_OPTION_HTTPS_MEM_TRUST’ Memory pointer to the CA certificate to be used by the HTTPS daemon to authenticate and trust clients certificates. This option should be followed by an "const char*" argument. The presence of this option activates the request of certificate to the client. The request to the client is marked optional, and it is the responsibility of the server to check the presence of the certificate if needed. Note that most browsers will only present a client certificate only if they have one matching the specified CA, not sending any certificate otherwise. ‘MHD_OPTION_HTTPS_CRED_TYPE’ Daemon credentials type. Either certificate or anonymous, this option should be followed by one of the values listed in "enum gnutls_credentials_type_t". ‘MHD_OPTION_HTTPS_PRIORITIES’ SSL/TLS protocol version and ciphers. This option must be followed by an "const char *" argument specifying the SSL/TLS protocol versions and ciphers that are acceptable for the application. The string is passed unchanged to gnutls_priority_init. If this option is not specified, "NORMAL" is used. ‘MHD_OPTION_HTTPS_CERT_CALLBACK’ Use a callback to determine which X.509 certificate should be used for a given HTTPS connection. This option should be followed by a argument of type "gnutls_certificate_retrieve_function2 *". This option provides an alternative to MHD_OPTION_HTTPS_MEM_KEY and MHD_OPTION_HTTPS_MEM_CERT. You must use this version if multiple domains are to be hosted at the same IP address using TLS's Server Name Indication (SNI) extension. In this case, the callback is expected to select the correct certificate based on the SNI information provided. The callback is expected to access the SNI data using gnutls_server_name_get(). Using this option requires GnuTLS 3.0 or higher. ‘MHD_OPTION_HTTPS_CERT_CALLBACK2’ Use a callback to determine which X.509 certificate should be used for a given HTTPS connection. This option should be followed by a argument of type 'gnutls_certificate_retrieve_function3 *'. This option provides an alternative/extension to #MHD_OPTION_HTTPS_CERT_CALLBACK. You must use this version if you want to use OCSP stapling. Using this option requires GnuTLS 3.6.3 or higher. ‘MHD_OPTION_GNUTLS_PSK_CRED_HANDLER’ Use pre-shared key for TLS credentials. Pass a pointer to callback of type ‘MHD_PskServerCredentialsCallback’ and a closure. The function will be called to retrieve the shared key for a given username. ‘MHD_OPTION_DIGEST_AUTH_RANDOM’ Digest Authentication nonce's seed. This option should be followed by two arguments. First an integer of type "size_t" which specifies the size of the buffer pointed to by the second argument in bytes. Note that the application must ensure that the buffer of the second argument remains allocated and unmodified while the daemon is running. For security, you SHOULD provide a fresh random nonce when using MHD with Digest Authentication. ‘MHD_OPTION_NONCE_NC_SIZE’ Size of an array of nonce and nonce counter map. This option must be followed by an "unsigned int" argument that have the size (number of elements) of a map of a nonce and a nonce-counter. If this option is not specified, a default value of 4 will be used (which might be too small for servers handling many requests). If you do not use digest authentication at all, you can specify a value of zero to save some memory. You should calculate the value of NC_SIZE based on the number of connections per second multiplied by your expected session duration plus a factor of about two for hash table collisions. For example, if you expect 100 digest-authenticated connections per second and the average user to stay on your site for 5 minutes, then you likely need a value of about 60000. On the other hand, if you can only expect only 10 digest-authenticated connections per second, tolerate browsers getting a fresh nonce for each request and expect a HTTP request latency of 250 ms, then a value of about 5 should be fine. ‘MHD_OPTION_LISTEN_SOCKET’ Listen socket to use. Pass a listen socket for MHD to use (systemd-style). If this option is used, MHD will not open its own listen socket(s). The argument passed must be of type "int" and refer to an existing socket that has been bound to a port and is listening. ‘MHD_OPTION_EXTERNAL_LOGGER’ Use the given function for logging error messages. This option must be followed by two arguments; the first must be a pointer to a function of type 'void fun(void * arg, const char * fmt, va_list ap)' and the second a pointer of type 'void*' which will be passed as the "arg" argument to "fun". Note that MHD will not generate any log messages without the MHD_USE_ERROR_LOG flag set and if MHD was compiled with the "-disable-messages" flag. ‘MHD_OPTION_THREAD_POOL_SIZE’ Number (unsigned int) of threads in thread pool. Enable thread pooling by setting this value to to something greater than 1. Currently, thread mode must be MHD_USE_INTERNAL_POLLING_THREAD if thread pooling is enabled (‘MHD_start_daemon’ returns ‘NULL’ for an unsupported thread mode). ‘MHD_OPTION_ARRAY’ This option can be used for initializing MHD using options from an array. A common use for this is writing an FFI for MHD. The actual options given are in an array of 'struct MHD_OptionItem', so this option requires a single argument of type 'struct MHD_OptionItem'. The array must be terminated with an entry ‘MHD_OPTION_END’. An example for code using MHD_OPTION_ARRAY is: struct MHD_OptionItem ops[] = { { MHD_OPTION_CONNECTION_LIMIT, 100, NULL }, { MHD_OPTION_CONNECTION_TIMEOUT, 10, NULL }, { MHD_OPTION_END, 0, NULL } }; d = MHD_start_daemon(0, 8080, NULL, NULL, dh, NULL, MHD_OPTION_ARRAY, ops, MHD_OPTION_END); For options that expect a single pointer argument, the second member of the ‘struct MHD_OptionItem’ is ignored. For options that expect two pointer arguments, the first argument must be cast to ‘intptr_t’. ‘MHD_OPTION_UNESCAPE_CALLBACK’ Specify a function that should be called for unescaping escape sequences in URIs and URI arguments. Note that this function will NOT be used by the MHD_PostProcessor. If this option is not specified, the default method will be used which decodes escape sequences of the form "%HH". This option should be followed by two arguments, the first one must be of the form size_t my_unescaper(void * cls, struct MHD_Connection *c, char *s) where the return value must be ‘strlen(s)’ and ‘s’ should be updated. Note that the unescape function must not lengthen ‘s’ (the result must be shorter than the input and still be 0-terminated). ‘cls’ will be set to the second argument following MHD_OPTION_UNESCAPE_CALLBACK. ‘MHD_OPTION_THREAD_STACK_SIZE’ Maximum stack size for threads created by MHD. This option must be followed by a ‘size_t’). Not specifying this option or using a value of zero means using the system default (which is likely to differ based on your platform). ‘MHD_OPTION_TCP_FASTQUEUE_QUEUE_SIZE’ When the flag ‘MHD_USE_TCP_FASTOPEN’ is used, this option sets the connection handshake queue size for the TCP FASTOPEN connections. Note that a TCP FASTOPEN connection handshake occupies more resources than a TCP handshake as the SYN packets also contain DATA which is kept in the associate state until handshake is completed. If this option is not given the queue size is set to a default value of 10. This option must be followed by a ‘unsigned int’. ‘MHD_OPTION_HTTPS_MEM_DHPARAMS’ Memory pointer for the Diffie-Hellman parameters (dh.pem) to be used by the HTTPS daemon for key exchange. This option must be followed by a ‘const char *’ argument. The argument would be a zero-terminated string with a PEM encoded PKCS3 DH parameters structure suitable for passing to ‘gnutls_dh_parms_import_pkcs3’. ‘MHD_OPTION_LISTENING_ADDRESS_REUSE’ This option must be followed by a ‘unsigned int’ argument. If this option is present and true (nonzero) parameter is given, allow reusing the address:port of the listening socket (using ‘SO_REUSEPORT’ on most platforms, and ‘SO_REUSEADDR’ on Windows). If a false (zero) parameter is given, disallow reusing the the address:port of the listening socket (this usually requires no special action, but ‘SO_EXCLUSIVEADDRUSE’ is needed on Windows). If this option is not present ‘SO_REUSEADDR’ is used on all platforms except Windows so reusing of address:port is disallowed. -- C Struct: MHD_OptionItem Entry in an MHD_OPTION_ARRAY. See the ‘MHD_OPTION_ARRAY’ option argument for its use. The ‘option’ member is used to specify which option is specified in the array. The other members specify the respective argument. Note that for options taking only a single pointer, the ‘ptr_value’ member should be set. For options taking two pointer arguments, the first pointer must be cast to ‘intptr_t’ and both the ‘value’ and the ‘ptr_value’ members should be used to pass the two pointers. -- Enumeration: MHD_ValueKind The ‘MHD_ValueKind’ specifies the source of the key-value pairs in the HTTP protocol. ‘MHD_HEADER_KIND’ HTTP header. ‘MHD_COOKIE_KIND’ Cookies. Note that the original HTTP header containing the cookie(s) will still be available and intact. ‘MHD_POSTDATA_KIND’ ‘POST’ data. This is available only if a content encoding supported by MHD is used (currently only URL encoding), and only if the posted content fits within the available memory pool. Note that in that case, the upload data given to the ‘MHD_AccessHandlerCallback()’ will be empty (since it has already been processed). ‘MHD_GET_ARGUMENT_KIND’ ‘GET’ (URI) arguments. ‘MHD_FOOTER_KIND’ HTTP footer (only for http 1.1 chunked encodings). -- Enumeration: MHD_RequestTerminationCode The ‘MHD_RequestTerminationCode’ specifies reasons why a request has been terminated (or completed). ‘MHD_REQUEST_TERMINATED_COMPLETED_OK’ We finished sending the response. ‘MHD_REQUEST_TERMINATED_WITH_ERROR’ Error handling the connection (resources exhausted, other side closed connection, application error accepting request, etc.) ‘MHD_REQUEST_TERMINATED_TIMEOUT_REACHED’ No activity on the connection for the number of seconds specified using ‘MHD_OPTION_CONNECTION_TIMEOUT’. ‘MHD_REQUEST_TERMINATED_DAEMON_SHUTDOWN’ We had to close the session since MHD was being shut down. -- Enumeration: MHD_ResponseMemoryMode The ‘MHD_ResponeMemoryMode’ specifies how MHD should treat the memory buffer given for the response in ‘MHD_create_response_from_buffer’. ‘MHD_RESPMEM_PERSISTENT’ Buffer is a persistent (static/global) buffer that won't change for at least the lifetime of the response, MHD should just use it, not free it, not copy it, just keep an alias to it. ‘MHD_RESPMEM_MUST_FREE’ Buffer is heap-allocated with ‘malloc’ (or equivalent) and should be freed by MHD after processing the response has concluded (response reference counter reaches zero). ‘MHD_RESPMEM_MUST_COPY’ Buffer is in transient memory, but not on the heap (for example, on the stack or non-malloc allocated) and only valid during the call to ‘MHD_create_response_from_buffer’. MHD must make its own private copy of the data for processing. -- Enumeration: MHD_ResponseFlags Response-specific flags. Passed as an argument to ‘MHD_set_response_options()’. ‘MHD_RF_NONE’ No special handling. ‘MHD_RF_HTTP_VERSION_1_0_ONLY’ Only respond in conservative HTTP 1.0-mode. In particular, do not (automatically) sent "Connection" headers and always close the connection after generating the response. By default, MHD will respond using the same HTTP version which was set in the request. You can also set the ‘MHD_RF_HTTP_VERSION_1_0_RESPONSE’ flag to force version 1.0 in the response. ‘MHD_RF_HTTP_VERSION_1_0_RESPONSE’ Only respond in HTTP 1.0-mode. Contrary to the ‘MHD_RF_HTTP_VERSION_1_0_ONLY’ flag, the response's HTTP version will always be set to 1.0 and "Connection" headers are still supported. You can even combine this option with MHD_RF_HTTP_VERSION_1_0_ONLY to change the response's HTTP version while maintaining strict compliance with HTTP 1.0 regarding connection management. This solution is not perfect as this flag is set on the response which is created after header processing. So MHD will behave as a HTTP 1.1 server until the response is queued. It means that an invalid HTTP 1.1 request will fail even if the response is sent with HTTP 1.0 and the request would be valid if interpreted with this version. For example, this request will fail in strict mode: GET / HTTP/1.1 as the "Host" header is missing and is mandatory in HTTP 1.1, but it should succeed when interpreted with HTTP 1.0. ‘MHD_RF_INSANITY_HEADER_CONTENT_LENGTH’ Disable sanity check preventing clients from manually setting the HTTP content length option. -- Enumeration: MHD_ResponseOptions Response-specific options. Passed in the varargs portion of ‘MHD_set_response_options()’. ‘MHD_RO_END’ No more options / last option. This is used to terminate the VARARGs list. -- Enumeration: MHD_WEBSOCKET_FLAG Options for the MHD websocket stream. This is used for initialization of a websocket stream when calling ‘MHD_websocket_stream_init’ or ‘MHD_websocket_stream_init2’ and alters the behavior of the websocket stream. Note that websocket streams are only available if you include the header file ‘microhttpd_ws.h’ and compiled _libmicrohttpd_ with websockets. ‘MHD_WEBSOCKET_FLAG_SERVER’ The websocket stream is initialized in server mode (default). Thus all outgoing payload will not be masked. All incoming payload must be masked. This flag cannot be used together with ‘MHD_WEBSOCKET_FLAG_CLIENT’. ‘MHD_WEBSOCKET_FLAG_CLIENT’ The websocket stream is initialized in client mode. You will usually never use that mode in combination with _libmicrohttpd_, because _libmicrohttpd_ provides a server and not a client. In client mode all outgoing payload will be masked (XOR-ed with random values). All incoming payload must be unmasked. If you use this mode, you must always call ‘MHD_websocket_stream_init2’ instead of ‘MHD_websocket_stream_init’, because you need to pass a random number generator callback function for masking. This flag cannot be used together with ‘MHD_WEBSOCKET_FLAG_SERVER’. ‘MHD_WEBSOCKET_FLAG_NO_FRAGMENTS’ You don't want to get fragmented data while decoding (default). Fragmented frames will be internally put together until they are complete. Whether or not data is fragmented is decided by the sender of the data during encoding. This cannot be used together with ‘MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS’. ‘MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS’ You want fragmented data, if it appears while decoding. You will receive the content of the fragmented frame, but if you are decoding text, you will never get an unfinished UTF-8 sequence (if the sequence appears between two fragments). Instead the text will end before the unfinished UTF-8 sequence. With the next fragment, which finishes the UTF-8 sequence, you will get the complete UTF-8 sequence. This cannot be used together with ‘MHD_WEBSOCKET_FLAG_NO_FRAGMENTS’. ‘MHD_WEBSOCKET_FLAG_GENERATE_CLOSE_FRAMES_ON_ERROR’ If the websocket stream becomes invalid during decoding due to protocol errors, a matching close frame will automatically be generated. The close frame will be returned via the parameters ‘payload’ and ‘payload_len’ of ‘MHD_websocket_decode’ and the return value is negative (a value of ‘enum MHD_WEBSOCKET_STATUS’). The generated close frame must be freed by the caller with ‘MHD_websocket_free’. -- Enumeration: MHD_WEBSOCKET_FRAGMENTATION This enumeration is used to specify the fragmentation behavior when encoding of data (text/binary) for a websocket stream. This is used with ‘MHD_websocket_encode_text’ or ‘MHD_websocket_encode_binary’. Note that websocket streams are only available if you include the header file ‘microhttpd_ws.h’ and compiled _libmicrohttpd_ with websockets. ‘MHD_WEBSOCKET_FRAGMENTATION_NONE’ You don't want to use fragmentation. The encoded frame consists of only one frame. ‘MHD_WEBSOCKET_FRAGMENTATION_FIRST’ You want to use fragmentation. The encoded frame is the first frame of a series of data frames of the same type (text or binary). You may send control frames (ping, pong or close) between these data frames. ‘MHD_WEBSOCKET_FRAGMENTATION_FOLLOWING’ You want to use fragmentation. The encoded frame is not the first frame of the series of data frames, but also not the last one. You may send control frames (ping, pong or close) between these data frames. ‘MHD_WEBSOCKET_FRAGMENTATION_LAST’ You want to use fragmentation. The encoded frame is the last frame of the series of data frames, but also not the first one. After this frame, you may send all types of frames again. -- Enumeration: MHD_WEBSOCKET_STATUS This enumeration is used for the return value of almost every websocket stream function. Errors are negative and values equal to or above zero mean a success. Positive values are only used by ‘MHD_websocket_decode’. Note that websocket streams are only available if you include the header file ‘microhttpd_ws.h’ and compiled _libmicrohttpd_ with websockets. ‘MHD_WEBSOCKET_STATUS_OK’ The call succeeded. Especially for ‘MHD_websocket_decode’ this means that no error occurred, but also no frame has been completed yet. For other functions this means simply a success. ‘MHD_WEBSOCKET_STATUS_TEXT_FRAME’ ‘MHD_websocket_decode’ has decoded a text frame. The parameters ‘payload’ and ‘payload_len’ are filled with the decoded text (if any). You must free the returned ‘payload’ after use with ‘MHD_websocket_free’. ‘MHD_WEBSOCKET_STATUS_BINARY_FRAME’ ‘MHD_websocket_decode’ has decoded a binary frame. The parameters ‘payload’ and ‘payload_len’ are filled with the decoded binary data (if any). You must free the returned ‘payload’ after use with ‘MHD_websocket_free’. ‘MHD_WEBSOCKET_STATUS_CLOSE_FRAME’ ‘MHD_websocket_decode’ has decoded a close frame. This means you must close the socket using ‘MHD_upgrade_action’ with ‘MHD_UPGRADE_ACTION_CLOSE’. You may respond with a close frame before closing. The parameters ‘payload’ and ‘payload_len’ are filled with the close reason (if any). The close reason starts with a two byte sequence of close code in network byte order (see ‘enum MHD_WEBSOCKET_CLOSEREASON’). After these two bytes a UTF-8 encoded close reason may follow. You can call ‘MHD_websocket_split_close_reason’ to split that close reason. You must free the returned ‘payload’ after use with ‘MHD_websocket_free’. ‘MHD_WEBSOCKET_STATUS_PING_FRAME’ ‘MHD_websocket_decode’ has decoded a ping frame. You should respond to this with a pong frame. The pong frame must contain the same binary data as the corresponding ping frame (if it had any). The parameters ‘payload’ and ‘payload_len’ are filled with the binary ping data (if any). You must free the returned ‘payload’ after use with ‘MHD_websocket_free’. ‘MHD_WEBSOCKET_STATUS_PONG_FRAME’ ‘MHD_websocket_decode’ has decoded a pong frame. You should usually only receive pong frames if you sent a ping frame before. The binary data should be equal to your ping frame and can be used to distinguish the response if you sent multiple ping frames. The parameters ‘payload’ and ‘payload_len’ are filled with the binary pong data (if any). You must free the returned ‘payload’ after use with ‘MHD_websocket_free’. ‘MHD_WEBSOCKET_STATUS_TEXT_FIRST_FRAGMENT’ ‘MHD_websocket_decode’ has decoded a text frame fragment. The parameters ‘payload’ and ‘payload_len’ are filled with the decoded text (if any). This is like ‘MHD_WEBSOCKET_STATUS_TEXT_FRAME’, but it can only appear if you specified ‘MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS’ during the call of ‘MHD_websocket_stream_init’ or ‘MHD_websocket_stream_init2’. You must free the returned ‘payload’ after use with ‘MHD_websocket_free’. ‘MHD_WEBSOCKET_STATUS_TEXT_FIRST_FRAGMENT’ ‘MHD_websocket_decode’ has decoded a binary frame fragment. The parameters ‘payload’ and ‘payload_len’ are filled with the decoded binary data (if any). This is like ‘MHD_WEBSOCKET_STATUS_BINARY_FRAME’, but it can only appear if you specified ‘MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS’ during the call of ‘MHD_websocket_stream_init’ or ‘MHD_websocket_stream_init2’. You must free the returned ‘payload’ after use with ‘MHD_websocket_free’. ‘MHD_WEBSOCKET_STATUS_TEXT_NEXT_FRAGMENT’ ‘MHD_websocket_decode’ has decoded the next text frame fragment. The parameters ‘payload’ and ‘payload_len’ are filled with the decoded text (if any). This is like ‘MHD_WEBSOCKET_STATUS_TEXT_FIRST_FRAGMENT’, but it appears only after the first and before the last fragment of a series of fragments. It can only appear if you specified ‘MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS’ during the call of ‘MHD_websocket_stream_init’ or ‘MHD_websocket_stream_init2’. You must free the returned ‘payload’ after use with ‘MHD_websocket_free’. ‘MHD_WEBSOCKET_STATUS_BINARY_NEXT_FRAGMENT’ ‘MHD_websocket_decode’ has decoded the next binary frame fragment. The parameters ‘payload’ and ‘payload_len’ are filled with the decoded binary data (if any). This is like ‘MHD_WEBSOCKET_STATUS_BINARY_FIRST_FRAGMENT’, but it appears only after the first and before the last fragment of a series of fragments. It can only appear if you specified ‘MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS’ during the call of ‘MHD_websocket_stream_init’ or ‘MHD_websocket_stream_init2’. You must free the returned ‘payload’ after use with ‘MHD_websocket_free’. ‘MHD_WEBSOCKET_STATUS_TEXT_LAST_FRAGMENT’ ‘MHD_websocket_decode’ has decoded the last text frame fragment. The parameters ‘payload’ and ‘payload_len’ are filled with the decoded text (if any). This is like ‘MHD_WEBSOCKET_STATUS_TEXT_FIRST_FRAGMENT’, but it appears only for the last fragment of a series of fragments. It can only appear if you specified ‘MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS’ during the call of ‘MHD_websocket_stream_init’ or ‘MHD_websocket_stream_init2’. You must free the returned ‘payload’ after use with ‘MHD_websocket_free’. ‘MHD_WEBSOCKET_STATUS_BINARY_LAST_FRAGMENT’ ‘MHD_websocket_decode’ has decoded the last binary frame fragment. The parameters ‘payload’ and ‘payload_len’ are filled with the decoded binary data (if any). This is like ‘MHD_WEBSOCKET_STATUS_BINARY_FIRST_FRAGMENT’, but it appears only for the last fragment of a series of fragments. It can only appear if you specified ‘MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS’ during the call of ‘MHD_websocket_stream_init’ or ‘MHD_websocket_stream_init2’. You must free the returned ‘payload’ after use with ‘MHD_websocket_free’. ‘MHD_WEBSOCKET_STATUS_PROTOCOL_ERROR’ The call failed and the stream is invalid now for decoding. You must close the websocket now using ‘MHD_upgrade_action’ with ‘MHD_UPGRADE_ACTION_CLOSE’. You may send a close frame before closing. This is only used by ‘MHD_websocket_decode’ and happens if the stream contains errors (i. e. invalid byte data). ‘MHD_WEBSOCKET_STATUS_STREAM_BROKEN’ You tried to decode something, but the stream has already been marked invalid. You must close the websocket now using ‘MHD_upgrade_action’ with ‘MHD_UPGRADE_ACTION_CLOSE’. You may send a close frame before closing. This is only used by ‘MHD_websocket_decode’ and happens if you call ‘MDM_websocket_decode’ again after has been invalidated. You can call ‘MHD_websocket_stream_is_valid’ at any time to check whether a stream is invalid or not. ‘MHD_WEBSOCKET_STATUS_MEMORY_ERROR’ A memory allocation failed. The stream remains valid. If this occurred while decoding, the decoding could be possible later if enough memory is available. This could happen while decoding if you received a too big data frame. You could try to specify max_payload_size during the call of ‘MHD_websocket_stream_init’ or ‘MHD_websocket_stream_init2’ to avoid this and close the websocket instead. ‘MHD_WEBSOCKET_STATUS_PARAMETER_ERROR’ You passed invalid parameters during the function call (i. e. a NULL pointer for a required parameter). The stream remains valid. ‘MHD_WEBSOCKET_STATUS_MAXIMUM_SIZE_EXCEEDED’ The maximum payload size has been exceeded. If you got this return code from ‘MHD_websocket_decode’ then the stream becomes invalid and the websocket must be closed using ‘MHD_upgrade_action’ with ‘MHD_UPGRADE_ACTION_CLOSE’. You may send a close frame before closing. The maximum payload size is specified during the call of ‘MHD_websocket_stream_init’ or ‘MHD_websocket_stream_init2’. This can also appear if you specified 0 as maximum payload size when the message is greater than the maximum allocatable memory size (i. e. more than 4 GiB on 32 bit systems). If you got this return code from ‘MHD_websocket_encode_close’, ‘MHD_websocket_encode_ping’ or ‘MHD_websocket_encode_pong’ then you passed to much payload data. The stream remains valid then. ‘MHD_WEBSOCKET_STATUS_UTF8_ENCODING_ERROR’ An UTF-8 sequence is invalid. If you got this return code from ‘MHD_websocket_decode’ then the stream becomes invalid and you must close the websocket using ‘MHD_upgrade_action’ with ‘MHD_UPGRADE_ACTION_CLOSE’. You may send a close frame before closing. If you got this from ‘MHD_websocket_encode_text’ or ‘MHD_websocket_encode_close’ then you passed invalid UTF-8 text. The stream remains valid then. ‘MHD_WEBSOCKET_STATUS_NO_WEBSOCKET_HANDSHAKE_HEADER’ A check routine for the HTTP headers came to the conclusion that the header value isn't valid for a websocket handshake request. This value can only be returned from the following functions: ‘MHD_websocket_check_http_version’, ‘MHD_websocket_check_connection_header’, ‘MHD_websocket_check_upgrade_header’, ‘MHD_websocket_check_version_header’, ‘MHD_websocket_create_accept_header’ -- Enumeration: MHD_WEBSOCKET_CLOSEREASON Enumeration of possible close reasons for websocket close frames. The possible values are specified in RFC 6455 7.4.1 These close reasons here are the default set specified by RFC 6455, but also other close reasons could be used. The definition is for short: • 0-999 are never used (if you pass 0 in ‘MHD_websocket_encode_close’ then no close reason is used). • 1000-2999 are specified by RFC 6455. • 3000-3999 are specified by libraries, etc. but must be registered by IANA. • 4000-4999 are reserved for private use. Note that websocket streams are only available if you include the header file ‘microhttpd_ws.h’ and compiled _libmicrohttpd_ with websockets. ‘MHD_WEBSOCKET_CLOSEREASON_NO_REASON’ This value is used as placeholder for ‘MHD_websocket_encode_close’ to tell that you don't want to specify any reason. If you use this value then no reason text may be used. This value cannot be a result of decoding, because this value is not a valid close reason for the websocket protocol. ‘MHD_WEBSOCKET_CLOSEREASON_REGULAR’ You close the websocket because it fulfilled its purpose and shall now be closed in a normal, planned way. ‘MHD_WEBSOCKET_CLOSEREASON_GOING_AWAY’ You close the websocket because you are shutting down the server or something similar. ‘MHD_WEBSOCKET_CLOSEREASON_PROTOCOL_ERROR’ You close the websocket because a protocol error occurred during decoding (i. e. invalid byte data). ‘MHD_WEBSOCKET_CLOSEREASON_UNSUPPORTED_DATATYPE’ You close the websocket because you received data which you don't accept. For example if you received a binary frame, but your application only expects text frames. ‘MHD_WEBSOCKET_CLOSEREASON_MALFORMED_UTF8’ You close the websocket because it contains malformed UTF-8. The UTF-8 validity is automatically checked by ‘MHD_websocket_decode’, so you don't need to check it on your own. UTF-8 is specified in RFC 3629. ‘MHD_WEBSOCKET_CLOSEREASON_POLICY_VIOLATED’ You close the websocket because you received a frame which is too big to process. You can specify the maximum allowed payload size during the call of ‘MHD_websocket_stream_init’ or ‘MHD_websocket_stream_init2’. ‘MHD_WEBSOCKET_CLOSEREASON_MISSING_EXTENSION’ This status code can be sent by the client if it expected a specific extension, but this extension hasn't been negotiated. ‘MHD_WEBSOCKET_CLOSEREASON_UNEXPECTED_CONDITION’ The server closes the websocket because it encountered an unexpected condition that prevented it from fulfilling the request. -- Enumeration: MHD_WEBSOCKET_UTF8STEP Enumeration of possible UTF-8 check steps for websocket functions These values are used during the encoding of fragmented text frames or for error analysis while encoding text frames. Its values specify the next step of the UTF-8 check. UTF-8 sequences consist of one to four bytes. This enumeration just says how long the current UTF-8 sequence is and what is the next expected byte. Note that websocket streams are only available if you include the header file ‘microhttpd_ws.h’ and compiled _libmicrohttpd_ with websockets. ‘MHD_WEBSOCKET_UTF8STEP_NORMAL’ There is no open UTF-8 sequence. The next byte must be 0x00-0x7F or 0xC2-0xF4. ‘MHD_WEBSOCKET_UTF8STEP_UTF2TAIL_1OF1’ The second byte of a two byte UTF-8 sequence. The first byte was 0xC2-0xDF.

Note that websocket streams are only available if you include the header file ‘microhttpd_ws.h’ and compiled _libmicrohttpd_ with websockets. ‘MHD_WEBSOCKET_VALIDITY_INVALID’ The stream is invalid. It cannot be used for decoding anymore. ‘MHD_WEBSOCKET_VALIDITY_VALID’ The stream is valid. Decoding works as expected. ‘MHD_WEBSOCKET_VALIDITY_ONLY_VALID_FOR_CONTROL_FRAMES’ The stream has received a close frame and is partly invalid. You can still use the stream for decoding, but if a data frame is received an error will be reported. After a close frame has been sent, no data frames may follow from the sender of the close frame.

With HTTP/1.1, multiple requests can be run over the same connection. However, MHD will only show one request per TCP connection to the client at any given time. -- C Struct: MHD_Response Handle for a response. -- C Struct: MHD_IoVec An element of an array of memory buffers. -- C Struct: MHD_PostProcessor Handle for ‘POST’ processing. -- C Union: MHD_ConnectionInfo Information about a connection. -- C Union: MHD_DaemonInfo Information about an MHD daemon. -- C Struct: MHD_WebSocketStream Information about a MHD websocket stream.  File: libmicrohttpd.info, Node: microhttpd-cb, Next: microhttpd-init, Prev: microhttpd-struct, Up: Top 4 Callback functions definition ******************************* -- Function Pointer: enum MHD_Result *MHD_AcceptPolicyCallback (void *cls, const struct sockaddr * addr, socklen_t addrlen) Invoked in the context of a connection to allow or deny a client to connect. This callback return ‘MHD_YES’ if connection is allowed, ‘MHD_NO’ if not. CLS custom value selected at callback registration time; ADDR address information from the client; ADDRLEN length of the address information. -- Function Pointer: enum MHD_Result *MHD_AccessHandlerCallback (void *cls, struct MHD_Connection * connection, const char *url, const char *method, const char *version, const char *upload_data, size_t *upload_data_size, void **req_cls) Invoked in the context of a connection to answer a request from the client. This callback must call MHD functions (example: the ‘MHD_Response’ ones) to provide content to give back to the client and return an HTTP status code (i.e. ‘200’ for OK, ‘404’, etc.). *note microhttpd-post::, for details on how to code this callback. Must return ‘MHD_YES’ if the connection was handled successfully, ‘MHD_NO’ if the socket must be closed due to a serious error while handling the request CLS custom value selected at callback registration time; URL the URL requested by the client; METHOD the HTTP method used by the client (‘GET’, ‘PUT’, ‘DELETE’, ‘POST’, etc.); VERSION the HTTP version string (i.e. ‘HTTP/1.1’); UPLOAD_DATA the data being uploaded (excluding headers): ‘POST’ data *will* be made available incrementally in UPLOAD_DATA; even if ‘POST’ data is available, the first time the callback is invoked there won't be upload data, as this is done just after MHD parses the headers. If supported by the client and the HTTP version, the application can at this point queue an error response to possibly avoid the upload entirely. If no response is generated, MHD will (if required) automatically send a 100 CONTINUE reply to the client. Afterwards, POST data will be passed to the callback to be processed incrementally by the application. The application may return ‘MHD_NO’ to forcefully terminate the TCP connection without generating a proper HTTP response. Once all of the upload data has been provided to the application, the application will be called again with 0 bytes of upload data. At this point, a response should be queued to complete the handling of the request. UPLOAD_DATA_SIZE set initially to the size of the UPLOAD_DATA provided; this callback must update this value to the number of bytes *NOT* processed; unless external select is used, the callback maybe required to process at least some data. If the callback fails to process data in multi-threaded or internal-select mode and if the read-buffer is already at the maximum size that MHD is willing to use for reading (about half of the maximum amount of memory allowed for the connection), then MHD will abort handling the connection and return an internal server error to the client. In order to avoid this, clients must be able to process upload data incrementally and reduce the value of ‘upload_data_size’. REQ_CLS reference to a pointer, initially set to ‘NULL’, that this callback can set to some address and that will be preserved by MHD for future calls for this request; since the access handler may be called many times (i.e., for a ‘PUT’/‘POST’ operation with plenty of upload data) this allows the application to easily associate some request-specific state; if necessary, this state can be cleaned up in the global ‘MHD_RequestCompletedCallback’ (which can be set with the ‘MHD_OPTION_NOTIFY_COMPLETED’). -- Function Pointer: void *MHD_RequestCompletedCallback (void *cls, struct MHD_Connectionconnection, void **req_cls, enum MHD_RequestTerminationCode toe) Signature of the callback used by MHD to notify the application about completed requests. CLS custom value selected at callback registration time; CONNECTION connection handle; REQ_CLS value as set by the last call to the ‘MHD_AccessHandlerCallback’; TOE reason for request termination see ‘MHD_OPTION_NOTIFY_COMPLETED’. -- Function Pointer: enum MHD_Result *MHD_KeyValueIterator (void *cls, enum MHD_ValueKind kind, const char *key, const char *value, size_t value_size) Iterator over key-value pairs. This iterator can be used to iterate over all of the cookies, headers, or ‘POST’-data fields of a request, and also to iterate over the headers that have been added to a response. CLS custom value specified when iteration was triggered; KIND kind of the header we are looking at KEY key for the value, can be an empty string VALUE value corresponding value, can be NULL VALUE_SIZE number of bytes in ‘value’. This argument was introduced in ‘MHD_VERSION’ 0x00096301 to allow applications to use binary zeros in values. Applications using this argument must ensure that they are using a sufficiently recent version of MHD, i.e. by testing ‘MHD_get_version()’ for values above or equal to 0.9.64. Applications that do not need zeros in values and that want to compile without warnings against newer versions of MHD should not declare this argument and cast the function pointer argument to ‘MHD_KeyValueIterator’. Return ‘MHD_YES’ to continue iterating, ‘MHD_NO’ to abort the iteration. -- Function Pointer: ssize_t *MHD_ContentReaderCallback (void *cls, uint64_t pos, char *buf, size_t max) Callback used by MHD in order to obtain content. The callback has to copy at most MAX bytes of content into BUF. The total number of bytes that has been placed into BUF should be returned. Note that returning zero will cause MHD to try again. Thus, returning zero should only be used in conjunction with ‘MHD_suspend_connection()’ to avoid busy waiting. While usually the callback simply returns the number of bytes written into BUF, there are two special return value: ‘MHD_CONTENT_READER_END_OF_STREAM’ (-1) should be returned for the regular end of transmission (with chunked encoding, MHD will then terminate the chunk and send any HTTP footers that might be present; without chunked encoding and given an unknown response size, MHD will simply close the connection; note that while returning ‘MHD_CONTENT_READER_END_OF_STREAM’ is not technically legal if a response size was specified, MHD accepts this and treats it just as ‘MHD_CONTENT_READER_END_WITH_ERROR’. ‘MHD_CONTENT_READER_END_WITH_ERROR’ (-2) is used to indicate a server error generating the response; this will cause MHD to simply close the connection immediately. If a response size was given or if chunked encoding is in use, this will indicate an error to the client. Note, however, that if the client does not know a response size and chunked encoding is not in use, then clients will not be able to tell the difference between ‘MHD_CONTENT_READER_END_WITH_ERROR’ and ‘MHD_CONTENT_READER_END_OF_STREAM’. This is not a limitation of MHD but rather of the HTTP protocol. CLS custom value selected at callback registration time; POS position in the datastream to access; note that if an ‘MHD_Response’ object is re-used, it is possible for the same content reader to be queried multiple times for the same data; however, if an ‘MHD_Response’ is not re-used, MHD guarantees that POS will be the sum of all non-negative return values obtained from the content reader so far. Return ‘-1’ on error (MHD will no longer try to read content and instead close the connection with the client). -- Function Pointer: void *MHD_ContentReaderFreeCallback (void *cls) This method is called by MHD if we are done with a content reader. It should be used to free resources associated with the content reader. -- Function Pointer: enum MHD_Result *MHD_PostDataIterator (void *cls, enum MHD_ValueKind kind, const char *key, const char *filename, const char *content_type, const char *transfer_encoding, const char *data, uint64_t off, size_t size) Iterator over key-value pairs where the value maybe made available in increments and/or may not be zero-terminated. Used for processing ‘POST’ data. CLS custom value selected at callback registration time; KIND type of the value; KEY zero-terminated key for the value; FILENAME name of the uploaded file, ‘NULL’ if not known; CONTENT_TYPE mime-type of the data, ‘NULL’ if not known; TRANSFER_ENCODING encoding of the data, ‘NULL’ if not known; DATA pointer to size bytes of data at the specified offset; OFF offset of data in the overall value; SIZE number of bytes in data available. Return ‘MHD_YES’ to continue iterating, ‘MHD_NO’ to abort the iteration. -- Function Pointer: void* *MHD_WebSocketMallocCallback (size_t buf_len) This callback function is used internally by many websocket functions for allocating data. By default ‘malloc’ is used. You can use your own allocation function with ‘MHD_websocket_stream_init2’ if you wish to. This can be useful for operating systems like Windows where ‘malloc’, ‘realloc’ and ‘free’ are compiler-dependent. You can call the associated ‘malloc’ callback of a websocket stream with ‘MHD_websocket_malloc’. BUF_LEN size of the buffer to allocate in bytes. Return the pointer of the allocated buffer or ‘NULL’ on failure. -- Function Pointer: void* *MHD_WebSocketReallocCallback (void *buf, size_t new_buf_len) This callback function is used internally by many websocket functions for reallocating data. By default ‘realloc’ is used. You can use your own reallocation function with ‘MHD_websocket_stream_init2’ if you wish to. This can be useful for operating systems like Windows where ‘malloc’, ‘realloc’ and ‘free’ are compiler-dependent. You can call the associated ‘realloc’ callback of a websocket stream with ‘MHD_websocket_realloc’. BUF current buffer, may be ‘NULL’; NEW_BUF_LEN new size of the buffer in bytes. Return the pointer of the reallocated buffer or ‘NULL’ on failure. On failure the old pointer must remain valid. -- Function Pointer: void *MHD_WebSocketFreeCallback (void *buf) This callback function is used internally by many websocket functions for freeing data. By default ‘free’ is used. You can use your own free function with ‘MHD_websocket_stream_init2’ if you wish to. This can be useful for operating systems like Windows where ‘malloc’, ‘realloc’ and ‘free’ are compiler-dependent. You can call the associated ‘free’ callback of a websocket stream with ‘MHD_websocket_free’. CLS current buffer to free, this may be ‘NULL’ then nothing happens. -- Function Pointer: size_t *MHD_WebSocketRandomNumberGenerator (void *cls, void* buf, size_t buf_len) This callback function is used for generating random numbers for masking payload data in client mode. If you use websockets in server mode with _libmicrohttpd_ then you don't need a random number generator, because the server doesn't mask its outgoing messages. However if you wish to use a websocket stream in client mode, you must pass this callback function to ‘MHD_websocket_stream_init2’. CLS closure specified in ‘MHD_websocket_stream_init2’; BUF buffer to fill with random values; BUF_LEN size of buffer in bytes. Return the number of generated random bytes. The return value should usually equal to buf_len.

CB function to call if MHD encounters a fatal internal error. If no handler was set explicitly, MHD will call ‘abort’. CLS closure argument for cb; the other arguments are the name of the source file, line number and a string describing the nature of the fatal error (which can be ‘NULL’) -- Function: struct MHD_Daemon * MHD_start_daemon (unsigned int flags, unsigned short port, MHD_AcceptPolicyCallback apc, void *apc_cls, MHD_AccessHandlerCallback dh, void *dh_cls, ...) Start a webserver on the given port. FLAGS OR-ed combination of ‘MHD_FLAG’ values; PORT port to bind to; APC callback to call to check which clients will be allowed to connect; you can pass ‘NULL’ in which case connections from any IP will be accepted; APC_CLS extra argument to APC; DH default handler for all URIs; DH_CLS extra argument to DH. Additional arguments are a list of options (type-value pairs, terminated with ‘MHD_OPTION_END’). It is mandatory to use ‘MHD_OPTION_END’ as last argument, even when there are no additional arguments. Return ‘NULL’ on error, handle to daemon on success. -- Function: MHD_socket MHD_quiesce_daemon (struct MHD_Daemon *daemon) Stop accepting connections from the listening socket. Allows clients to continue processing, but stops accepting new connections. Note that the caller is responsible for closing the returned socket; however, if MHD is run using threads (anything but external select mode), it must not be closed until AFTER ‘MHD_stop_daemon’ has been called (as it is theoretically possible that an existing thread is still using it). This function is useful in the special case that a listen socket is to be migrated to another process (i.e. a newer version of the HTTP server) while existing connections should continue to be processed until they are finished. Return ‘-1’ on error (daemon not listening), the handle to the listen socket otherwise. -- Function: void MHD_stop_daemon (struct MHD_Daemon *daemon) Shutdown an HTTP daemon. -- Function: enum MHD_Result MHD_run (struct MHD_Daemon *daemon) Run webserver operations (without blocking unless in client callbacks). This method should be called by clients in combination with ‘MHD_get_fdset()’ if the client-controlled ‘select’-method is used. This function will work for external ‘poll’ and ‘select’ mode. However, if using external ‘select’ mode, you may want to instead use ‘MHD_run_from_select’, as it is more efficient. DAEMON daemon to process connections of Return ‘MHD_YES’ on success, ‘MHD_NO’ if this daemon was not started with the right options for this call. -- Function: enum MHD_Result MHD_run_from_select (struct MHD_Daemon *daemon, const fd_set *read_fd_set, const fd_set *write_fd_set, const fd_set *except_fd_set) Run webserver operations given sets of ready socket handles. This method should be called by clients in combination with ‘MHD_get_fdset’ if the client-controlled (external) select method is used. You can use this function instead of ‘MHD_run’ if you called ‘select’ on the result from ‘MHD_get_fdset’. File descriptors in the sets that are not controlled by MHD will be ignored. Calling this function instead of ‘MHD_run’ is more efficient as MHD will not have to call ‘select’ again to determine which operations are ready. DAEMON daemon to process connections of READ_FD_SET set of descriptors that must be ready for reading without blocking WRITE_FD_SET set of descriptors that must be ready for writing without blocking EXCEPT_FD_SET ignored, can be NULL Return ‘MHD_YES’ on success, ‘MHD_NO’ on serious internal errors. -- Function: void MHD_add_connection (struct MHD_Daemon *daemon, int client_socket, const struct sockaddr *addr, socklen_t addrlen) Add another client connection to the set of connections managed by MHD. This API is usually not needed (since MHD will accept inbound connections on the server socket). Use this API in special cases, for example if your HTTP server is behind NAT and needs to connect out to the HTTP client, or if you are building a proxy. If you use this API in conjunction with a internal select or a thread pool, you must set the option ‘MHD_USE_ITC’ to ensure that the freshly added connection is immediately processed by MHD. The given client socket will be managed (and closed!) by MHD after this call and must no longer be used directly by the application afterwards. DAEMON daemon that manages the connection CLIENT_SOCKET socket to manage (MHD will expect to receive an HTTP request from this socket next). ADDR IP address of the client ADDRLEN number of bytes in addr This function will return ‘MHD_YES’ on success, ‘MHD_NO’ if this daemon could not handle the connection (i.e. malloc failed, etc). The socket will be closed in any case; 'errno' is set to indicate further details about the error.  File: libmicrohttpd.info, Node: microhttpd-inspect, Next: microhttpd-requests, Prev: microhttpd-init, Up: Top 6 Implementing external ‘select’ ******************************** -- Function: enum MHD_Result MHD_get_fdset (struct MHD_Daemon *daemon, fd_set * read_fd_set, fd_set * write_fd_set, fd_set * except_fd_set, int *max_fd) Obtain the ‘select()’ sets for this daemon. The daemon's socket is added to READ_FD_SET. The list of currently existent connections is scanned and their file descriptors added to the correct set. When calling this function, FD_SETSIZE is assumed to be platform's default. If you changed FD_SETSIZE for your application, you should use ‘MHD_get_fdset2()’ instead. This function should only be called in when MHD is configured to use external select with ‘select()’ or with ‘epoll()’. In the latter case, it will only add the single ‘epoll()’ file descriptor used by MHD to the sets. After the call completed successfully: the variable referenced by MAX_FD references the file descriptor with highest integer identifier. The variable must be set to zero before invoking this function. Return ‘MHD_YES’ on success, ‘MHD_NO’ if: the arguments are invalid (example: ‘NULL’ pointers); this daemon was not started with the right options for this call. -- Function: enum MHD_Result MHD_get_fdset2 (struct MHD_Daemon *daemon, fd_set * read_fd_set, fd_set * write_fd_set, fd_set * except_fd_set, int *max_fd, unsigned int fd_setsize) Like ‘MHD_get_fdset()’, except that you can manually specify the value of FD_SETSIZE used by your application. -- Function: enum MHD_Result MHD_get_timeout (struct MHD_Daemon *daemon, unsigned long long *timeout) Obtain timeout value for select for this daemon (only needed if connection timeout is used). The returned value is how many milliseconds ‘select’ should at most block, not the timeout value set for connections. This function must not be called if the ‘MHD_USE_THREAD_PER_CONNECTION’ mode is in use (since then it is not meaningful to ask for a timeout, after all, there is concurrenct activity). The function must also not be called by user-code if ‘MHD_USE_INTERNAL_POLLING_THREAD’ is in use. In the latter case, the behavior is undefined. DAEMON which daemon to obtain the timeout from. TIMEOUT will be set to the timeout (in milliseconds). Return ‘MHD_YES’ on success, ‘MHD_NO’ if timeouts are not used (or no connections exist that would necessitate the use of a timeout right now).  File: libmicrohttpd.info, Node: microhttpd-requests, Next: microhttpd-responses, Prev: microhttpd-inspect, Up: Top 7 Handling requests ******************* -- Function: int MHD_get_connection_values (struct MHD_Connection *connection, enum MHD_ValueKind kind, MHD_KeyValueIterator iterator, void *iterator_cls) Get all the headers matching KIND from the request. The KIND argument can be a bitmask, ORing the various header kinds that are requested. The ITERATOR callback is invoked once for each header, with ITERATOR_CLS as first argument. After version 0.9.19, the headers are iterated in the same order as they were received from the network; previous versions iterated over the headers in reverse order. ‘MHD_get_connection_values’ returns the number of entries iterated over; this can be less than the number of headers if, while iterating, ITERATOR returns ‘MHD_NO’. ITERATOR can be ‘NULL’: in this case this function just counts and returns the number of headers. In the case of ‘MHD_GET_ARGUMENT_KIND’, the VALUE argument will be ‘NULL’ if the URL contained a key without an equals operator. For example, for a HTTP request to the URL "http://foo/bar?key", the VALUE argument is ‘NULL’; in contrast, a HTTP request to the URL "http://foo/bar?key=", the VALUE argument is the empty string. The normal case is that the URL contains "http://foo/bar?key=value" in which case VALUE would be the string "value" and KEY would contain the string "key". -- Function: enum MHD_Result MHD_set_connection_value (struct MHD_Connection *connection, enum MHD_ValueKind kind, const char *key, const char *value) This function can be used to append an entry to the list of HTTP headers of a connection (so that the ‘MHD_get_connection_values function’ will return them - and the MHD PostProcessor will also see them). This maybe required in certain situations (see Mantis #1399) where (broken) HTTP implementations fail to supply values needed by the post processor (or other parts of the application). This function MUST only be called from within the MHD_AccessHandlerCallback (otherwise, access maybe improperly synchronized). Furthermore, the client must guarantee that the key and value arguments are 0-terminated strings that are NOT freed until the connection is closed. (The easiest way to do this is by passing only arguments to permanently allocated strings.). CONNECTION is the connection for which the entry for KEY of the given KIND should be set to the given VALUE. The function returns ‘MHD_NO’ if the operation could not be performed due to insufficient memory and ‘MHD_YES’ on success. -- Function: const char * MHD_lookup_connection_value (struct MHD_Connection *connection, enum MHD_ValueKind kind, const char *key) Get a particular header value. If multiple values match the KIND, return one of them (the "first", whatever that means). KEY must reference a zero-terminated ASCII-coded string representing the header to look for: it is compared against the headers using (basically) ‘strcasecmp()’, so case is ignored. -- Function: const char * MHD_lookup_connection_value_n (struct MHD_Connection *connection, enum MHD_ValueKind kind, const char *key, size_t key_size, const char **value_ptr, size_t *value_size_ptr) Get a particular header value. If multiple values match the KIND, return one of them (the "first", whatever that means). KEY must reference an ASCII-coded string representing the header to look for: it is compared against the headers using (basically) ‘strncasecmp()’, so case is ignored. The VALUE_PTR is set to the address of the value found, and VALUE_SIZE_PTR is set to the number of bytes in the value.  File: libmicrohttpd.info, Node: microhttpd-responses, Next: microhttpd-flow, Prev: microhttpd-requests, Up: Top 8 Building responses to requests ******************************** Response objects handling by MHD is asynchronous with respect to the application execution flow. Instances of the ‘MHD_Response’ structure are not associated to a daemon and neither to a client connection: they are managed with reference counting. In the simplest case: we allocate a new ‘MHD_Response’ structure for each response, we use it once and finally we destroy it. MHD allows more efficient resources usages. Example: we allocate a new ‘MHD_Response’ structure for each response *kind*, we use it every time we have to give that response and we finally destroy it only when the daemon shuts down. * Menu: * microhttpd-response enqueue:: Enqueuing a response. * microhttpd-response create:: Creating a response object. * microhttpd-response headers:: Adding headers to a response. * microhttpd-response options:: Setting response options. * microhttpd-response inspect:: Inspecting a response object. * microhttpd-response upgrade:: Creating a response for protocol upgrades.  File: libmicrohttpd.info, Node: microhttpd-response enqueue, Next: microhttpd-response create, Up: microhttpd-responses 8.1 Enqueuing a response ======================== -- Function: enum MHD_Result MHD_queue_response (struct MHD_Connection *connection, unsigned int status_code, struct MHD_Response *response) Queue a response to be transmitted to the client as soon as possible but only after MHD_AccessHandlerCallback returns. This function checks that it is legal to queue a response at this time for the given connection. It also increments the internal reference counter for the response object (the counter will be decremented automatically once the response has been transmitted). CONNECTION the connection identifying the client; STATUS_CODE HTTP status code (i.e. ‘200’ for OK); RESPONSE response to transmit. Return ‘MHD_YES’ on success or if message has been queued. Return ‘MHD_NO’: if arguments are invalid (example: ‘NULL’ pointer); on error (i.e. reply already sent). -- Function: void MHD_destroy_response (struct MHD_Response *response) Destroy a response object and associated resources (decrement the reference counter). Note that MHD may keep some of the resources around if the response is still in the queue for some clients, so the memory may not necessarily be freed immediately. An explanation of reference counting(1): 1. a ‘MHD_Response’ object is allocated: struct MHD_Response * response = MHD_create_response_from_buffer(...); /* here: reference counter = 1 */ 2. the ‘MHD_Response’ object is enqueued in a ‘MHD_Connection’: MHD_queue_response(connection, , response); /* here: reference counter = 2 */ 3. the creator of the response object discharges responsibility for it: MHD_destroy_response(response); /* here: reference counter = 1 */ 4. the daemon handles the connection sending the response's data to the client then decrements the reference counter by calling ‘MHD_destroy_response()’: the counter's value drops to zero and the ‘MHD_Response’ object is released. ---------- Footnotes ---------- (1) Note to readers acquainted to the Tcl API: reference counting on ‘MHD_Connection’ structures is handled in the same way as Tcl handles ‘Tcl_Obj’ structures through ‘Tcl_IncrRefCount()’ and ‘Tcl_DecrRefCount()’.  File: libmicrohttpd.info, Node: microhttpd-response create, Next: microhttpd-response headers, Prev: microhttpd-response enqueue, Up: microhttpd-responses 8.2 Creating a response object ============================== -- Function: struct MHD_Response * MHD_create_response_from_callback (uint64_t size, size_t block_size, MHD_ContentReaderCallback crc, void *crc_cls, MHD_ContentReaderFreeCallback crfc) Create a response object. The response object can be extended with header information and then it can be used any number of times. SIZE size of the data portion of the response, ‘-1’ for unknown; BLOCK_SIZE preferred block size for querying CRC (advisory only, MHD may still call CRC using smaller chunks); this is essentially the buffer size used for IO, clients should pick a value that is appropriate for IO and memory performance requirements; CRC callback to use to obtain response data; CRC_CLS extra argument to CRC; CRFC callback to call to free CRC_CLS resources. Return ‘NULL’ on error (i.e. invalid arguments, out of memory). -- Function: struct MHD_Response * MHD_create_response_from_fd (uint64_t size, int fd) Create a response object. The response object can be extended with header information and then it can be used any number of times. SIZE size of the data portion of the response (should be smaller or equal to the size of the file) FD file descriptor referring to a file on disk with the data; will be closed when response is destroyed; note that 'fd' must be an actual file descriptor (not a pipe or socket) since MHD might use 'sendfile' or 'seek' on it. The descriptor should be in blocking-IO mode. Return ‘NULL’ on error (i.e. invalid arguments, out of memory). -- Function: struct MHD_Response * MHD_create_response_from_pipe (int fd) Create a response object. The response object can be extended with header information and then it can be used ONLY ONCE. FD file descriptor of the read-end of the pipe; will be closed when response is destroyed. The descriptor should be in blocking-IO mode. Return ‘NULL’ on error (i.e. out of memory). -- Function: struct MHD_Response * MHD_create_response_from_fd_at_offset (size_t size, int fd, off_t offset) Create a response object. The response object can be extended with header information and then it can be used any number of times. Note that you need to be a bit careful about ‘off_t’ when writing this code. Depending on your platform, MHD is likely to have been compiled with support for 64-bit files. When you compile your own application, you must make sure that ‘off_t’ is also a 64-bit value. If not, your compiler may pass a 32-bit value as ‘off_t’, which will result in 32-bits of garbage. If you use the autotools, use the ‘AC_SYS_LARGEFILE’ autoconf macro and make sure to include the generated ‘config.h’ file before ‘microhttpd.h’ to avoid problems. If you do not have a build system and only want to run on a GNU/Linux system, you could also use #define _FILE_OFFSET_BITS 64 #include #include #include #include to ensure 64-bit ‘off_t’. Note that if your operating system does not support 64-bit files, MHD will be compiled with a 32-bit ‘off_t’ (in which case the above would be wrong). SIZE size of the data portion of the response (number of bytes to transmit from the file starting at offset).

The strings referenced by HEADER and CONTENT must be zero-terminated and they are duplicated into memory blocks embedded in RESPONSE. Notice that the strings must not hold newlines, carriage returns or tab chars. MHD_add_response_header() prevents applications from setting a "Transfer-Encoding" header to values other than "identity" or "chunked" as other transfer encodings are not supported by MHD. Note that usually MHD will pick the transfer encoding correctly automatically, but applications can use the header to force a particular behavior. MHD_add_response_header() also prevents applications from setting a "Content-Length" header. MHD will automatically set a correct "Content-Length" header if it is possible and allowed. Return ‘MHD_NO’ on error (i.e. invalid header or content format or memory allocation error). -- Function: enum MHD_Result MHD_add_response_footer (struct MHD_Response *response, const char *footer, const char *content) Add a footer line to the response. The strings referenced by FOOTER and CONTENT must be zero-terminated and they are duplicated into memory blocks embedded in RESPONSE. Notice that the strings must not hold newlines, carriage returns or tab chars. You can add response footers at any time before signalling the end of the response to MHD (not just before calling 'MHD_queue_response'). Footers are useful for adding cryptographic checksums to the reply or to signal errors encountered during data generation. This call was introduced in MHD 0.9.3.

Invoke the ITERATOR callback for each header in the response, using ITERATOR_CLS as first argument. Return number of entries iterated over. ITERATOR can be ‘NULL’: in this case the function just counts headers. ITERATOR should not modify the its key and value arguments, unless we know what we are doing. -- Function: const char * MHD_get_response_header (struct MHD_Response *response, const char *key) Find and return a pointer to the value of a particular header from the response. KEY must reference a zero-terminated string representing the header to look for. The search is case sensitive. Return ‘NULL’ if header does not exist or KEY is ‘NULL’. We should not modify the value, unless we know what we are doing.  File: libmicrohttpd.info, Node: microhttpd-response upgrade, Prev: microhttpd-response inspect, Up: microhttpd-responses 8.6 Creating a response for protocol upgrades ============================================= With RFC 2817 a mechanism to switch protocols within HTTP was introduced. Here, a client sends a request with a "Connection: Upgrade" header. The server responds with a "101 Switching Protocols" response header, after which the two parties begin to speak a different (non-HTTP) protocol over the TCP connection. This mechanism is used for upgrading HTTP 1.1 connections to HTTP2 or HTTPS, as well as for implementing WebSockets. Which protocol upgrade is performed is negotiated between server and client in additional headers, in particular the "Upgrade" header. MHD supports switching protocols using this mechanism only if the ‘MHD_ALLOW_SUSPEND_RESUME’ flag has been set when starting the daemon. If this flag has been set, applications can upgrade a connection by queueing a response (using the ‘MHD_HTTP_SWITCHING_PROTOCOLS’ status code) which must have been created with the following function: -- Function: enum MHD_Result MHD_create_response_for_upgrade (MHD_UpgradeHandler upgrade_handler, void *upgrade_handler_cls) Create a response suitable for switching protocols. Returns ‘MHD_YES’ on success. ‘upgrade_handler’ must not be ‘NULL’. When creating this type of response, the "Connection: Upgrade" header will be set automatically for you. MHD requires that you additionally set an "Upgrade:" header. The "Upgrade" header must simply exist, the specific value is completely up to the application. The ‘upgrade_handler’ argument to the above has the following type: -- Function Pointer: void *MHD_UpgradeHandler (void *cls, struct MHD_Connection *connection, const char *extra_in, size_t extra_in_size, MHD_socket sock, struct MHD_UpgradeResponseHandle *urh) This function will be called once MHD has transmitted the header of the response to the connection that is being upgraded. At this point, the application is expected to take over the socket ‘sock’ and speak the non-HTTP protocol to which the connection was upgraded. MHD will no longer use the socket; this includes handling timeouts. The application must call ‘MHD_upgrade_action’ with an upgrade action of ‘MHD_UPGRADE_ACTION_CLOSE’ when it is done processing the connection to close the socket. The application must not call ‘MHD_stop_daemon’ on the respective daemon as long as it is still handling the connection. The arguments given to the ‘upgrade_handler’ have the following meaning: CLS matches the ‘upgrade_handler_cls’ that was given to ‘MHD_create_response_for_upgrade’ CONNECTION identifies the connection that is being upgraded; REQ_CLS last value left in '*req_cls' in the 'MHD_AccessHandlerCallback' EXTRA_IN buffer of bytes MHD read "by accident" from the socket already. This can happen if the client eagerly transmits more than just the HTTP request. The application should treat these as if it had read them from the socket. EXTRA_IN_SIZE number of bytes in ‘extra_in’ SOCK the socket which the application can now use directly for some bi-directional communication with the client. The application can henceforth use ‘recv()’ and ‘send()’ or ‘read()’ and ‘write()’ system calls on the socket. However, ‘ioctl()’ and ‘setsockopt()’ functions will not work as expected when using HTTPS. Such operations may be supported in the future via ‘MHD_upgrade_action’. Most importantly, the application must never call ‘close()’ on this socket. Closing the socket must be done using ‘MHD_upgrade_action’. However, while close is forbidden, the application may call ‘shutdown()’ on the socket. URH argument for calls to ‘MHD_upgrade_action’. Applications must eventually use this function to perform the ‘close()’ action on the socket. -- Function: enum MHD_Result MHD_upgrade_action (struct MHD_UpgradeResponseHandle *urh, enum MHD_UpgradeAction action, ...) Perform special operations related to upgraded connections. URH identifies the upgraded connection to perform an action on ACTION specifies the action to perform; further arguments to the function depend on the specifics of the action. -- Enumeration: MHD_UpgradeAction Set of actions to be performed on upgraded connections. Passed as an argument to ‘MHD_upgrade_action()’. ‘MHD_UPGRADE_ACTION_CLOSE’ Closes the connection. Must be called once the application is done with the client. Takes no additional arguments. ‘MHD_UPGRADE_ACTION_CORK_ON’ Enable corking on the underlying socket. ‘MHD_UPGRADE_ACTION_CORK_OFF’ Disable corking on the underlying socket.  File: libmicrohttpd.info, Node: microhttpd-flow, Next: microhttpd-dauth, Prev: microhttpd-responses, Up: Top 9 Flow control. *************** Sometimes it may be possible that clients upload data faster than an application can process it, or that an application needs an extended period of time to generate a response. If ‘MHD_USE_THREAD_PER_CONNECTION’ is used, applications can simply deal with this by performing their logic within the thread and thus effectively blocking connection processing by MHD. In all other modes, blocking logic must not be placed within the callbacks invoked by MHD as this would also block processing of other requests, as a single thread may be responsible for tens of thousands of connections. Instead, applications using thread modes other than ‘MHD_USE_THREAD_PER_CONNECTION’ should use the following functions to perform flow control. -- Function: enum MHD_Result MHD_suspend_connection (struct MHD_Connection *connection) Suspend handling of network data for a given connection. This can be used to dequeue a connection from MHD's event loop (external select, internal select or thread pool; not applicable to thread-per-connection!) for a while. If you use this API in conjunction with a internal select or a thread pool, you must set the option ‘MHD_ALLOW_SUSPEND_RESUME’ to ensure that a resumed connection is immediately processed by MHD. Suspended connections continue to count against the total number of connections allowed (per daemon, as well as per IP, if such limits are set). Suspended connections will NOT time out; timeouts will restart when the connection handling is resumed. While a connection is suspended, MHD will not detect disconnects by the client. The only safe time to suspend a connection is from the ‘MHD_AccessHandlerCallback’ or from the respective ‘MHD_ContentReaderCallback’ (but in this case the response object must not be shared among multiple connections). When suspending from the ‘MHD_AccessHandlerCallback’ you MUST afterwards return ‘MHD_YES’ from the access handler callback (as MHD_NO would imply to both close and suspend the connection, which is not allowed). Finally, it is an API violation to call ‘MHD_stop_daemon’ while having suspended connections (this will at least create memory and socket leaks or lead to undefined behavior). You must explicitly resume all connections before stopping the daemon. CONNECTION the connection to suspend -- Function: enum MHD_Result MHD_resume_connection (struct MHD_Connection *connection) Resume handling of network data for suspended connection. It is safe to resume a suspended connection at any time. Calling this function on a connection that was not previously suspended will result in undefined behavior. If you are using this function in "external" select mode, you must make sure to run ‘MHD_run’ afterwards (before again calling ‘MHD_get_fdset’), as otherwise the change may not be reflected in the set returned by ‘MHD_get_fdset’ and you may end up with a connection that is stuck until the next network activity. You can check whether a connection is currently suspended using ‘MHD_get_connection_info’ by querying for ‘MHD_CONNECTION_INFO_CONNECTION_SUSPENDED’. CONNECTION the connection to resume  File: libmicrohttpd.info, Node: microhttpd-dauth, Next: microhttpd-post, Prev: microhttpd-flow, Up: Top 10 Utilizing Authentication *************************** MHD support three types of client authentication. Basic authentication uses a simple authentication method based on BASE64 algorithm. Username and password are exchanged in clear between the client and the server, so this method must only be used for non-sensitive content or when the session is protected with https. When using basic authentication MHD will have access to the clear password, possibly allowing to create a chained authentication toward an external authentication server. Digest authentication uses a one-way authentication method based on MD5 hash algorithm. Only the hash will transit over the network, hence protecting the user password. The nonce will prevent replay attacks. This method is appropriate for general use, especially when https is not used to encrypt the session. Client certificate authentication uses a X.509 certificate from the client. This is the strongest authentication mechanism but it requires the use of HTTPS. Client certificate authentication can be used simultaneously with Basic or Digest Authentication in order to provide a two levels authentication (like for instance separate machine and user authentication). A code example for using client certificates is presented in the MHD tutorial. * Menu: * microhttpd-dauth basic:: Using Basic Authentication. * microhttpd-dauth digest:: Using Digest Authentication.

MHD provides the post processor API to make it easier for applications to parse the data of a client's ‘POST’ request: the ‘MHD_AccessHandlerCallback’ will be invoked multiple times to process data as it arrives; at each invocation a new chunk of data must be processed. The arguments UPLOAD_DATA and UPLOAD_DATA_SIZE are used to reference the chunk of data. When ‘MHD_AccessHandlerCallback’ is invoked for a new request: its ‘*REQ_CLS’ argument is set to ‘NULL’. When ‘POST’ data comes in the upload buffer it is *mandatory* to use the REQ_CLS to store a reference to per-request data. The fact that the pointer was initially ‘NULL’ can be used to detect that this is a new request. One method to detect that a new request was started is to set ‘*req_cls’ to an unused integer: int access_handler (void *cls, struct MHD_Connection * connection, const char *url, const char *method, const char *version, const char *upload_data, size_t *upload_data_size, void **req_cls) { static int old_connection_marker; int new_connection = (NULL == *req_cls); if (new_connection) { /* new connection with POST */ *req_cls = &old_connection_marker; } ... } In contrast to the previous example, for ‘POST’ requests in particular, it is more common to use the value of ‘*req_cls’ to keep track of actual state used during processing, such as the post processor (or a struct containing a post processor): int access_handler (void *cls, struct MHD_Connection * connection, const char *url, const char *method, const char *version, const char *upload_data, size_t *upload_data_size, void **req_cls) { struct MHD_PostProcessor * pp = *req_cls; if (pp == NULL) { pp = MHD_create_post_processor(connection, ...); *req_cls = pp; return MHD_YES; } if (*upload_data_size) { MHD_post_process(pp, upload_data, *upload_data_size); *upload_data_size = 0; return MHD_YES; } else { MHD_destroy_post_processor(pp); return MHD_queue_response(...); } } Note that the callback from ‘MHD_OPTION_NOTIFY_COMPLETED’ should be used to destroy the post processor.

Call this function when ‘POST’ data is available (usually during an ‘MHD_AccessHandlerCallback’) with the UPLOAD_DATA and UPLOAD_DATA_SIZE. Whenever possible, this will then cause calls to the ‘MHD_IncrementalKeyValueIterator’. PP the post processor; POST_DATA POST_DATA_LEN bytes of ‘POST’ data; POST_DATA_LEN length of POST_DATA. Return ‘MHD_YES’ on success, ‘MHD_NO’ on error (out-of-memory, iterator aborted, parse error). -- Function: enum MHD_Result MHD_destroy_post_processor (struct MHD_PostProcessor *pp) Release PostProcessor resources. After this function is being called, the PostProcessor is guaranteed to no longer call its iterator. There is no special call to the iterator to indicate the end of the post processing stream. After destroying the PostProcessor, the programmer should perform any necessary work to complete the processing of the iterator. Return ‘MHD_YES’ if processing completed nicely, ‘MHD_NO’ if there were spurious characters or formatting problems with the post request. It is common to ignore the return value of this function.

Obtain information about the given daemon. This function is currently not fully implemented. DAEMON the daemon about which information is desired; INFOTYPE type of information that is desired ... additional arguments about the desired information (depending on infoType) Returns a union with the respective member (depending on infoType) set to the desired information), or ‘NULL’ in case the desired information is not available or applicable. -- Enumeration: MHD_DaemonInfoType Values of this enum are used to specify what information about a daemon is desired. ‘MHD_DAEMON_INFO_KEY_SIZE’ Request information about the key size for a particular cipher algorithm. The cipher algorithm should be passed as an extra argument (of type 'enum MHD_GNUTLS_CipherAlgorithm'). No longer supported, using this value will cause ‘MHD_get_daemon_info’ to return NULL. ‘MHD_DAEMON_INFO_MAC_KEY_SIZE’ Request information about the key size for a particular cipher algorithm. The cipher algorithm should be passed as an extra argument (of type 'enum MHD_GNUTLS_HashAlgorithm'). No longer supported, using this value will cause ‘MHD_get_daemon_info’ to return NULL. ‘MHD_DAEMON_INFO_LISTEN_FD’ Request the file-descriptor number that MHD is using to listen to the server socket. This can be useful if no port was specified and a client needs to learn what port is actually being used by MHD. No extra arguments should be passed. ‘MHD_DAEMON_INFO_EPOLL_FD’ Request the file-descriptor number that MHD is using for epoll. If the build is not supporting epoll, NULL is returned; if we are using a thread pool or this daemon was not started with ‘MHD_USE_EPOLL’, (a pointer to) -1 is returned. If we are using ‘MHD_USE_INTERNAL_POLLING_THREAD’ or are in 'external' select mode, the internal epoll FD is returned. This function must be used in external select mode with epoll to obtain the FD to call epoll on. No extra arguments should be passed. ‘MHD_DAEMON_INFO_CURRENT_CONNECTIONS’ Request the number of current connections handled by the daemon. No extra arguments should be passed and a pointer to a ‘union MHD_DaemonInfo’ value is returned, with the ‘num_connections’ member of type ‘unsigned int’ set to the number of active connections. Note that in multi-threaded or internal-select mode, the real number of current connections may already be different when ‘MHD_get_daemon_info’ returns. The number of current connections can be used (even in multi-threaded and internal-select mode) after ‘MHD_quiesce_daemon’ to detect whether all connections have been handled.

Obtain information about the given connection. CONNECTION the connection about which information is desired; INFOTYPE type of information that is desired ... additional arguments about the desired information (depending on infoType) Returns a union with the respective member (depending on infoType) set to the desired information), or ‘NULL’ in case the desired information is not available or applicable. -- Enumeration: MHD_ConnectionInfoType Values of this enum are used to specify what information about a connection is desired. ‘MHD_CONNECTION_INFO_CIPHER_ALGO’ What cipher algorithm is being used (HTTPS connections only). ‘NULL’ is returned for non-HTTPS connections. Takes no extra arguments. ‘MHD_CONNECTION_INFO_PROTOCOL,’ Allows finding out the TLS/SSL protocol used (HTTPS connections only). ‘NULL’ is returned for non-HTTPS connections. Takes no extra arguments. ‘MHD_CONNECTION_INFO_CLIENT_ADDRESS’ Returns information about the address of the client. Returns essentially a ‘struct sockaddr **’ (since the API returns a ‘union MHD_ConnectionInfo *’ and that union contains a ‘struct sockaddr *’). Takes no extra arguments. ‘MHD_CONNECTION_INFO_GNUTLS_SESSION,’ Takes no extra arguments. Allows access to the underlying GNUtls session, including access to the underlying GNUtls client certificate (HTTPS connections only). Takes no extra arguments. ‘NULL’ is returned for non-HTTPS connections. Takes no extra arguments. ‘MHD_CONNECTION_INFO_GNUTLS_CLIENT_CERT,’ Dysfunctional (never implemented, deprecated). Use MHD_CONNECTION_INFO_GNUTLS_SESSION to get the ‘gnutls_session_t’ and then call ‘gnutls_certificate_get_peers()’. ‘MHD_CONNECTION_INFO_DAEMON’ Returns information about ‘struct MHD_Daemon’ which manages this connection. Takes no extra arguments. ‘MHD_CONNECTION_INFO_CONNECTION_FD’ Returns the file descriptor (usually a TCP socket) associated with this connection (in the "connect-fd" member of the returned struct). Note that manipulating the descriptor directly can have problematic consequences (as in, break HTTP). Applications might use this access to manipulate TCP options, for example to set the "TCP-NODELAY" option for COMET-like applications. Note that MHD will set TCP-CORK after sending the HTTP header and clear it after finishing the footers automatically (if the platform supports it). As the connection callbacks are invoked in between, those might be used to set different values for TCP-CORK and TCP-NODELAY in the meantime. Takes no extra arguments. ‘MHD_CONNECTION_INFO_CONNECTION_SUSPENDED’ Returns pointer to an integer that is ‘MHD_YES’ if the connection is currently suspended (and thus can be safely resumed) and ‘MHD_NO’ otherwise. Takes no extra arguments. ‘MHD_CONNECTION_INFO_SOCKET_CONTEXT’ Returns the client-specific pointer to a ‘void *’ that was (possibly) set during a ‘MHD_NotifyConnectionCallback’ when the socket was first accepted. Note that this is NOT the same as the ‘req_cls’ argument of the ‘MHD_AccessHandlerCallback’. The ‘req_cls’ is fresh for each HTTP request, while the ‘socket_context’ is fresh for each socket. Takes no extra arguments. ‘MHD_CONNECTION_INFO_CONNECTION_TIMEOUT’ Returns pointer to an ‘unsigned int’ that is the current timeout used for the connection (in seconds, 0 for no timeout). Note that while suspended connections will not timeout, the timeout value returned for suspended connections will be the timeout that the connection will use after it is resumed, and thus might not be zero. Takes no extra arguments. ‘MHD_CONNECTION_INFO_REQUEST_HEADER_SIZE’ Returns pointer to an ‘size_t’ that represents the size of the HTTP header received from the client. Only valid after the first callback to the access handler. Takes no extra arguments. ‘MHD_CONNECTION_INFO_HTTP_STATUS’ Returns the HTTP status code of the response that was queued.

Decoding is done until either a frame is complete or the end of the byte sequence is reached. WS websocket stream for decoding. STREAMBUF byte sequence for decoding. This is what you typically received via ‘recv()’. STREAMBUF_LEN length of the byte sequence in parameter ‘streambuf’. STREAMBUF_READ_LEN pointer to a variable, which receives the number of bytes, that has been processed by this call.

The remaining bytes of ‘buf’ must be passed to the next call of this function. PAYLOAD pointer to a variable, which receives the allocated buffer with the payload data of the decoded frame. Must not be ‘NULL’. If no decoded data is available or an error occurred ‘NULL’ is returned. When the returned value is not ‘NULL’ then the buffer contains always ‘payload_len’ bytes plus one terminating ‘NUL’ character (regardless of the frame type).

If you passed the flag ‘MHD_WEBSOCKET_FLAG_GENERATE_CLOSE_FRAMES_ON_ERROR’ upon creation of the websocket stream and a decoding error occurred (function return value less than 0), then this buffer contains a generated close frame, which must be sent via the socket to the recipient. If you passed the flag ‘MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS’ upon creation of the websocket stream then this payload may only be a part of the complete message. Only complete UTF-8 sequences are returned for fragmented text frames. If necessary the UTF-8 sequence will be completed with the next text fragment. PAYLOAD_LEN pointer to a variable, which receives length of the result ‘payload’ buffer in bytes. Must not be ‘NULL’. This receives 0 when no data is available, when the decoded payload has a length of zero or when an error occurred. Returns a value greater than zero when a frame is complete. Compare with ‘enum MHD_WEBSOCKET_STATUS’ to distinguish the frame type. Returns 0 when the call succeeded, but no frame is available.

This must be UTF-8 encoded. If you don't want UTF-8 then send a binary frame with ‘MHD_websocket_encode_binary()’ instead. May be be ‘NULL’ if ‘payload_utf8_len’ is 0, must not be ‘NULL’ otherwise. PAYLOAD_UTF8_LEN length of ‘payload_utf8’ in bytes. FRAGMENTATION A value of ‘enum MHD_WEBSOCKET_FRAGMENTATION’ to specify the fragmentation behavior. Specify ‘MHD_WEBSOCKET_FRAGMENTATION_NONE’ or just 0 if you don't want to use fragmentation (default). FRAME pointer to a variable, which receives a buffer with the encoded text frame. Must not be ‘NULL’. The buffer contains what you typically send via ‘send()’ to the recipient. If no encoded data is available the variable receives ‘NULL’. If the variable is not ‘NULL’ then the buffer contains always ‘frame_len’ bytes plus one terminating ‘NUL’ character. The caller must free this buffer using ‘MHD_websocket_free()’. FRAME_LEN pointer to a variable, which receives the length of the encoded frame in bytes. Must not be ‘NULL’. UTF8_STEP If fragmentation is used (the parameter ‘fragmentation’ is not 0) then is parameter is required and must not be ‘NULL’. If no fragmentation is used, this parameter is optional and should be ‘NULL’. This parameter is a pointer to a variable which contains the last check status of the UTF-8 sequence. It is required to continue a previous UTF-8 sequence check when fragmentation is used, because a UTF-8 sequence could be split upon fragments. ‘enum MHD_WEBSOCKET_UTF8STEP’ is used for this value. If you start a new fragment using ‘MHD_WEBSOCKET_FRAGMENTATION_NONE’ or ‘MHD_WEBSOCKET_FRAGMENTATION_FIRST’ the old value of this variable will be discarded and the value of this variable will be initialized to ‘MHD_WEBSOCKET_UTF8STEP_NORMAL’.

Must not be ‘NULL’. The buffer contains what you typically send via ‘send()’ to the recipient. If no encoded data is available the variable receives ‘NULL’. If the variable is not ‘NULL’ then the buffer contains always ‘frame_len’ bytes plus one terminating ‘NUL’ character. The caller must free this buffer using ‘MHD_websocket_free()’. FRAME_LEN pointer to a variable, which receives the length of the encoded frame in bytes. Must not be ‘NULL’. Returns 0 on success or a value less than zero on errors. Can be compared with ‘enum MHD_WEBSOCKET_STATUS’. -- Function: enum MHD_WEBSOCKET_STATUS MHD_websocket_encode_close (struct MHD_WebSocketStream* ws, unsigned short reason_code, const char* reason_utf8, size_t reason_utf8_len, char** frame, size_t* frame_len) Encodes a websocket close frame. Close frames are used to close a websocket connection in a formal way. WS websocket stream; REASON_CODE reason for close. You can use ‘enum MHD_WEBSOCKET_CLOSEREASON’ for typical reasons, but you are not limited to these values. The allowed values are specified in RFC 6455 7.4. If you don't want to enter a reason, you can specify ‘MHD_WEBSOCKET_CLOSEREASON_NO_REASON’ (or just 0) then no reason is encoded. REASON_UTF8 An UTF-8 encoded text reason why the connection is closed. This may be ‘NULL’ if ‘reason_utf8_len’ is 0. This must be ‘NULL’ if ‘reason_code’ equals to zero (‘MHD_WEBSOCKET_CLOSEREASON_NO_REASON’). REASON_UTF8_LEN length of the UTF-8 encoded text reason in bytes. This may not exceed 123 bytes. FRAME pointer to a variable, which receives a buffer with the encoded close frame. Must not be ‘NULL’. The buffer contains what you typically send via ‘send()’ to the recipient. If no encoded data is available the variable receives ‘NULL’. If the variable is not ‘NULL’ then the buffer contains always ‘frame_len’ bytes plus one terminating ‘NUL’ character. The caller must free this buffer using ‘MHD_websocket_free()’. FRAME_LEN pointer to a variable, which receives the length of the encoded frame in bytes. Must not be ‘NULL’. Returns 0 on success or a value less than zero on errors. Can be compared with ‘enum MHD_WEBSOCKET_STATUS’.

The memory allocation function could be different for a websocket stream if ‘MHD_websocket_stream_init2()’ has been used for initialization. WS websocket stream; BUF_LEN size of the buffer to allocate in bytes. Returns the pointer of the allocated buffer or ‘NULL’ on failure. -- Function: void* MHD_websocket_realloc (struct MHD_WebSocketStream* ws, void* buf, size_t new_buf_len) Reallocates memory with the associated ‘realloc()’ function of the websocket stream. The memory reallocation function could be different for a websocket stream if ‘MHD_websocket_stream_init2()’ has been used for initialization. WS websocket stream; BUF current buffer, may be ‘NULL’; NEW_BUF_LEN new size of the buffer in bytes. Return the pointer of the reallocated buffer or ‘NULL’ on failure. On failure the old pointer remains valid. -- Function: void MHD_websocket_free (struct MHD_WebSocketStream* ws, void* buf) Frees memory with the associated ‘free()’ function of the websocket stream. The memory free function could be different for a websocket stream if ‘MHD_websocket_stream_init2()’ has been used for initialization. WS websocket stream; BUF buffer to free, this may be ‘NULL’ then nothing happens.

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble -------- The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the “Lesser†General Public License because it does _Less_ to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION --------------------------------------------------------------- 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a. The modified work must itself be a software library. b. You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c. You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d. If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a. Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b. Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c. Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d. If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e. Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a. Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b. Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS --------------------------- How to Apply These Terms to Your New Libraries ---------------------------------------------- If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. ONE LINE TO GIVE THE LIBRARY'S NAME AND AN IDEA OF WHAT IT DOES.

Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

Preamble ======== The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION =============================================================== 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a. You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b. You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c. If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a. Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b. Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c. Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs ======================================================= If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES. Copyright (C) YYYY NAME OF AUTHOR This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) YEAR NAME OF AUTHOR Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands ‘show w’ and ‘show c’ should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than ‘show w’ and ‘show c’; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. SIGNATURE OF TY COON, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.  File: libmicrohttpd.info, Node: GNU-FDL, Next: Concept Index, Prev: GNU-GPL, Up: Top GNU-FDL ******* Version 1.3, 3 November 2008 Copyright © 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. 0. PREAMBLE The purpose of this License is to make a manual, textbook, or other functional and useful document “free†in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others. This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software. We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference. 1. APPLICABILITY AND DEFINITIONS This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law. A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language. A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them. The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none. The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words. A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque". Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only. The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text. The "publisher" means any person or entity that distributes copies of the Document to the public. A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition. The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License. 2. VERBATIM COPYING You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3. You may also lend copies, under the same conditions stated above, and you may publicly display copies. 3. COPYING IN QUANTITY If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects. If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages. If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public. It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document. 4. MODIFICATIONS You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version: A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. C. State on the Title page the name of the publisher of the Modified Version, as the publisher. D. Preserve all the copyright notices of the Document. E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below. G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice. H. Include an unaltered copy of this License. I. Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the "History" section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. K. For any section Entitled "Acknowledgements" or "Dedications", Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles. M. Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version. N. Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant Section. O. Preserve any Warranty Disclaimers. If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles. You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard. You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one. The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version. 5. COMBINING DOCUMENTS You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers. The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. In the combination, you must combine any sections Entitled "History" in the various original documents, forming one section Entitled "History"; likewise combine any sections Entitled "Acknowledgements", and any sections Entitled "Dedications". You must delete all sections Entitled "Endorsements." 6. COLLECTIONS OF DOCUMENTS You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects. You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document. 7. AGGREGATION WITH INDEPENDENT WORKS A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document. If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate. 8. TRANSLATION Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail. If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title. 9. TERMINATION You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License. However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it. 10. FUTURE REVISIONS OF THIS LICENSE The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See . Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Document. 11. RELICENSING "Massive Multiauthor Collaboration Site" (or "MMC Site") means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A "Massive Multiauthor Collaboration" (or "MMC") contained in the site means any set of copyrightable works thus published on the MMC site. "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization. "Incorporate" means to publish or republish a Document, in whole or in part, as part of another Document. An MMC is "eligible for relicensing" if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008. The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing. ADDENDUM: How to use this License for your documents ==================================================== To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page: Copyright (C) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled ``GNU Free Documentation License''. If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the "with...Texts." line with this: with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation. If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.

MHD is a small HTTP daemon library. As such, it does not have any API for logging errors (you can only enable or disable logging to stderr). Also, it may not support all of the HTTP features directly, where applicable, portions of HTTP may have to be handled by clients of the library. The library is supposed to handle everything that it must handle (because the API would not allow clients to do this), such as basic connection management. However, detailed interpretations of headers, such as range requests, are left to the main application. In particular, if an application developer wants to support range requests, he needs to explicitly indicate support in responses and also explicitly parse the range header and generate a response (for example, using the @code{MHD_create_response_from_fd_at_offset} call to serve ranges from a file). MHD does understands headers that control connection management (specifically, @code{Connection: close} and @code{Expect: 100 continue} are understood and handled automatically). @code{Connection: upgrade} is supported by passing control over the socket (or something that behaves like the real socket in the case of TLS) to the application (after sending the desired HTTP response header). MHD largely ignores the semantics of the different HTTP methods, so clients are left to handle those. One exception is that MHD does understand @code{HEAD} and will only send the headers of the response and not the body, even if the client supplied a body. (In fact, clients do need to construct a response with the correct length, even for @code{HEAD} request.) MHD understands @code{POST} data and is able to decode certain formats (at the moment only @code{application/x-www-form-urlencoded} and @code{multipart/form-data}) using the post processor API. The data stream of a POST is also provided directly to the main application, so unsupported encodings could still be processed, just not conveniently by MHD. The header file defines various constants used by the HTTP protocol. This does not mean that MHD actually interprets all of these values. The provided constants are exported as a convenience for users of the library. MHD does not verify that transmitted HTTP headers are part of the standard specification; users of the library are free to define their own extensions of the HTTP standard and use those with MHD. All functions are guaranteed to be completely reentrant and thread-safe. MHD checks for allocation failures and tries to recover gracefully (for example, by closing the connection). Additionally, clients can specify resource limits on the overall number of connections, number of connections per IP address and memory used per connection to avoid resource exhaustion. @section Scope MHD is currently used in a wide range of implementations. Examples based on reports we've received from developers include: @itemize @item Embedded HTTP server on a cortex M3 (128 KB code space) @item Large-scale multimedia server (reportedly serving at the simulator limit of 7.5 GB/s) @item Administrative console (via HTTP/HTTPS) for network appliances @c If you have other interesting examples, please let us know @end itemize @section Thread modes and event loops @cindex poll @cindex epoll @cindex select MHD supports four basic thread modes and up to three event loop styles. The four basic thread modes are external sockets polling (MHD creates no threads, event loop is fully managed by the application), internal polling (MHD creates one thread for all connections), polling in thread pool (MHD creates a thread pool which is used to process all connections) and thread-per-connection (MHD creates one thread for listen sockets and then one thread per accepted connection). These thread modes are then combined with the evet loop styles (polling function type). MHD support select, poll and epoll. select is available on all platforms, epoll and poll may not be available on some platforms. Note that it is possible to combine MHD using epoll with an external select-based event loop. The default (if no other option is passed) is ``external select''. The highest performance can typically be obtained with a thread pool using @code{epoll}. Apache Benchmark (ab) was used to compare the performance of @code{select} and @code{epoll} when using a thread pool and a large number of connections. @ref{fig:performance} shows the resulting plot from the @code{benchmark.c} example, which measures the latency between an incoming request and the completion of the transmission of the response. In this setting, the @code{epoll} thread pool with four threads was able to handle more than 45,000 connections per second on loopback (with Apache Benchmark running three processes on the same machine). @cindex performance @float Figure,fig:performance @image{libmicrohttpd_performance_data,400pt,300pt,Data,.png} @caption{Performance measurements for select vs. epoll (with thread-pool).} @end float Not all combinations of thread modes and event loop styles are supported. This is partially to keep the API simple, and partially because some combinations simply make no sense as others are strictly superior. Note that the choice of style depends first of all on the application logic, and then on the performance requirements. Applications that perform a blocking operation while handling a request within the callbacks from MHD must use a thread per connection. This is typically rather costly. Applications that do not support threads or that must run on embedded devices without thread-support must use the external mode. Using @code{epoll} is only supported on some platform, thus portable applications must at least have a fallback option available. @ref{tbl:supported} lists the sane combinations. @float Table,tbl:supported @multitable {@b{thread-per-connection}} {@b{select}} {@b{poll}} {@b{epoll}} @item @tab @b{select} @tab @b{poll} @tab @b{epoll} @item @b{external} @tab yes @tab no @tab yes @item @b{internal} @tab yes @tab yes @tab yes @item @b{thread pool} @tab yes @tab yes @tab yes @item @b{thread-per-connection} @tab yes @tab yes @tab no @end multitable @caption{Supported combinations of event styles and thread modes.} @end float @section Compiling GNU libmicrohttpd @cindex compilation @cindex embedded systems @cindex portability MHD uses the standard GNU system where the usual build process involves running @verbatim $ ./configure $ make $ make install @end verbatim MHD supports various options to be given to configure to tailor the binary to a specific situation. Note that some of these options will remove portions of the MHD code that are required for binary-compatibility. They should only be used on embedded systems with tight resource constraints and no concerns about library versioning. Standard distributions including MHD are expected to always ship with all features enabled, otherwise unexpected incompatibilities can arise! Here is a list of MHD-specific options that can be given to configure (canonical configure options such as ``--prefix'' are also supported, for a full list of options run ``./configure --help''): @table @code @item ``--disable-curl'' disable running testcases using libcurl @item ``--disable-largefile'' disable support for 64-bit files @item ``--disable-messages'' disable logging of error messages (smaller binary size, not so much fun for debugging) @item ``--disable-https'' disable HTTPS support, even if GNUtls is found; this option must be used if eCOS license is desired as an option (in all cases the resulting binary falls under a GNU LGPL-only license) @item ``--disable-postprocessor'' do not include the post processor API (results in binary incompatibility) @item ``--disable-dauth'' do not include the authentication APIs (results in binary incompatibility) @item ``--disable-httpupgrade'' do not build code for HTTP ``Upgrade'' (smaller binary size, binary incompatible library) @item ``--disable-epoll'' do not include epoll support, even if it supported (minimally smaller binary size, good for portability testing) @item ``--enable-coverage'' set flags for analysis of code-coverage with gcc/gcov (results in slow, large binaries) @item ``--with-threads=posix,w32,none,auto'' sets threading library to use. With use ``none'' to not support threads. In this case, MHD will only support the ``external'' threading modes and not perform any locking of data structures! Use @code{MHD_is_feature_supported(MHD_FEATURE_THREADS)} to test if threads are available. Default is ``auto''. @item ``--with-gcrypt=PATH'' specifies path to libgcrypt installation @item ``--with-gnutls=PATH'' specifies path to libgnutls installation @end table To cross-compile MHD for Android, install the Android NDK and use: @verbatim ./configure --target=arm-linux-androideabi --host=arm-linux-androideabi --disable-doc --disable-examples make @end verbatim Similar build commands should work for cross-compilation to other platforms. Note that you may have to first cross-compile GnuTLS to get MHD with TLS support. @section Validity of pointers MHD will give applications access to its internal data structures via pointers via arguments and return values from its API. This creates the question as to how long those pointers are assured to stay valid. Most MHD data structures are associated with the connection of an HTTP client. Thus, pointers associated with a connection are typically valid until the connection is finished, at which point MHD will call the @code{MHD_RequestCompletedCallback} if one is registered. Applications that have such a callback registered may assume that keys and values from the @code{MHD_KeyValueIterator}, return values from @code{MHD_lookup_connection_value} and the @code{url}, @code{method} and @code{version} arguments to the @code{MHD_AccessHandlerCallback} will remain valid until the respective @code{MHD_RequestCompletedCallback} is invoked. In contrast, the @code{upload_data} argument of @code{MHD_RequestCompletedCallback} as well as all pointers from the @code{MHD_PostDataIterator} are only valid for the duration of the callback. Pointers returned from @code{MHD_get_response_header} are valid as long as the response itself is valid. @section Including the microhttpd.h header @cindex portability @cindex microhttpd.h Ideally, before including "microhttpd.h" you should add the necessary includes to define the @code{va_list}, @code{size_t}, @code{ssize_t}, @code{intptr_t}, @code{off_t}, @code{uint8_t}, @code{uint16_t}, @code{int32_t}, @code{uint32_t}, @code{int64_t}, @code{uint64_t}, @code{fd_set}, @code{socklen_t} and @code{struct sockaddr} data types. Which specific headers are needed may depend on your platform and your build system might include some tests to provide you with the necessary conditional operations. For possible suggestions consult @code{platform.h} and @code{configure.ac} in the MHD distribution. Once you have ensured that you manually (!) included the right headers for your platform before "microhttpd.h", you should also add a line with @code{#define MHD_PLATFORM_H} which will prevent the "microhttpd.h" header from trying (and, depending on your platform, failing) to include the right headers. If you do not define MHD_PLATFORM_H, the "microhttpd.h" header will automatically include headers needed on GNU/Linux systems (possibly causing problems when porting to other platforms). @section SIGPIPE @cindex signals MHD does not install a signal handler for SIGPIPE. On platforms where this is possible (such as GNU/Linux), it disables SIGPIPE for its I/O operations (by passing MSG_NOSIGNAL or similar). On other platforms, SIGPIPE signals may be generated from network operations by MHD and will cause the process to die unless the developer explicitly installs a signal handler for SIGPIPE. Hence portable code using MHD must install a SIGPIPE handler or explicitly block the SIGPIPE signal. MHD does not do so in order to avoid messing with other parts of the application that may need to handle SIGPIPE in a particular way. You can make your application handle SIGPIPE by calling the following function in @code{main}: @verbatim static void catcher (int sig) { } static void ignore_sigpipe () { struct sigaction oldsig; struct sigaction sig; sig.sa_handler = &catcher; sigemptyset (&sig.sa_mask); #ifdef SA_INTERRUPT sig.sa_flags = SA_INTERRUPT; /* SunOS */ #else sig.sa_flags = SA_RESTART; #endif if (0 != sigaction (SIGPIPE, &sig, &oldsig)) fprintf (stderr, "Failed to install SIGPIPE handler: %s\n", strerror (errno)); } @end verbatim @section MHD_UNSIGNED_LONG_LONG @cindex long long @cindex MHD_LONG_LONG @cindex IAR @cindex ARM @cindex cortex m3 @cindex embedded systems Some platforms do not support @code{long long}. Hence MHD defines a macro @code{MHD_UNSIGNED LONG_LONG} which will default to @code{unsigned long long}. For standard desktop operating systems, this is all you need to know. However, if your platform does not support @code{unsigned long long}, you should change "platform.h" to define @code{MHD_LONG_LONG} and @code{MHD_UNSIGNED_LONG_LONG} to an appropriate alternative type and also define @code{MHD_LONG_LONG_PRINTF} and @code{MHD_UNSIGNED_LONG_LONG_PRINTF} to the corresponding format string for printing such a data type. Note that the ``signed'' versions are deprecated. Also, for historical reasons, @code{MHD_LONG_LONG_PRINTF} is without the percent sign, whereas @code{MHD_UNSIGNED_LONG_LONG_PRINTF} is with the percent sign. Newly written code should only use the unsigned versions. However, you need to define both in "platform.h" if you need to change the definition for the specific platform. @section Portability to W32 libmicrohttpd in general ported well to W32. Most libmicrohttpd features are supported. W32 do not support some functions, like epoll and corresponding MHD features are not available on W32. @section Portability to z/OS To compile MHD on z/OS, extract the archive and run @verbatim iconv -f UTF-8 -t IBM-1047 contrib/ascebc > /tmp/ascebc.sh chmod +x /tmp/ascebc.sh for n in `find * -type f` do /tmp/ascebc.sh $n done @end verbatim to convert all source files to EBCDIC. Note that you must run @code{configure} from the directory where the configure script is located. Otherwise, configure will fail to find the @code{contrib/xcc} script (which is a wrapper around the z/OS c89 compiler). @c ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ @c ------------------------------------------------------------ @node microhttpd-const @chapter Constants @deftp {Enumeration} MHD_FLAG Options for the MHD daemon. Note that MHD will run automatically in background thread(s) only if @code{MHD_USE_INTERNAL_POLLING_THREAD} is used. Otherwise caller (application) must use @code{MHD_run} or @code{MHD_run_from_select} to have MHD processed network connections and data. Starting the daemon may also fail if a particular option is not implemented or not supported on the target platform (i.e. no support for @acronym{TLS}, threads or IPv6). TLS support generally depends on options given during MHD compilation. @table @code @item MHD_NO_FLAG No options selected. @item MHD_USE_ERROR_LOG If this flag is used, the library should print error messages and warnings to stderr (or to custom error printer if it's specified by options). Note that for this run-time option to have any effect, MHD needs to be compiled with messages enabled. This is done by default except you ran configure with the @code{--disable-messages} flag set. @item MHD_USE_DEBUG @cindex debugging Currently the same as @code{MHD_USE_ERROR_LOG}. @item MHD_USE_TLS @cindex TLS @cindex SSL Run in HTTPS-mode. If you specify @code{MHD_USE_TLS} and MHD was compiled without SSL support, @code{MHD_start_daemon} will return NULL. @item MHD_USE_THREAD_PER_CONNECTION Run using one thread per connection. @item MHD_USE_INTERNAL_POLLING_THREAD Run using an internal thread doing @code{SELECT}. @item MHD_USE_IPv6 @cindex IPv6 Run using the IPv6 protocol (otherwise, MHD will just support IPv4). If you specify @code{MHD_USE_IPV6} and the local platform does not support it, @code{MHD_start_daemon} will return NULL. If you want MHD to support IPv4 and IPv6 using a single socket, pass MHD_USE_DUAL_STACK, otherwise, if you only pass this option, MHD will try to bind to IPv6-only (resulting in no IPv4 support). @item MHD_USE_DUAL_STACK @cindex IPv6 Use a single socket for IPv4 and IPv6. Note that this will mean that IPv4 addresses are returned by MHD in the IPv6-mapped format (the 'struct sockaddr_in6' format will be used for IPv4 and IPv6). @item MHD_USE_PEDANTIC_CHECKS @cindex deprecated Deprecated (use @code{MHD_OPTION_STRICT_FOR_CLIENT}). Be pedantic about the protocol. Specifically, at the moment, this flag causes MHD to reject HTTP 1.1 connections without a @code{Host} header. This is required by the standard, but of course in violation of the ``be as liberal as possible in what you accept'' norm. It is recommended to turn this @strong{ON} if you are testing clients against MHD, and @strong{OFF} in production. @item MHD_USE_POLL @cindex FD_SETSIZE @cindex poll @cindex select Use @code{poll()} instead of @code{select()}. This allows sockets with descriptors @code{>= FD_SETSIZE}. This option currently only works in conjunction with @code{MHD_USE_INTERNAL_POLLING_THREAD} (at this point). If you specify @code{MHD_USE_POLL} and the local platform does not support it, @code{MHD_start_daemon} will return NULL. @item MHD_USE_EPOLL @cindex FD_SETSIZE @cindex epoll @cindex select Use @code{epoll()} instead of @code{poll()} or @code{select()}. This allows sockets with descriptors @code{>= FD_SETSIZE}. This option is only available on some systems and does not work in conjunction with @code{MHD_USE_THREAD_PER_CONNECTION} (at this point). If you specify @code{MHD_USE_EPOLL} and the local platform does not support it, @code{MHD_start_daemon} will return NULL. Using @code{epoll()} instead of @code{select()} or @code{poll()} can in some situations result in significantly higher performance as the system call has fundamentally lower complexity (O(1) for @code{epoll()} vs. O(n) for @code{select()}/@code{poll()} where n is the number of open connections). @item MHD_USE_TURBO @cindex performance Enable optimizations to aggressively improve performance. Currently, the optimizations this option enables are based on opportunistic reads and writes. Basically, MHD will simply try to read or write or accept on a socket before checking that the socket is ready for IO using the event loop mechanism. As the sockets are non-blocking, this may fail (at a loss of performance), but generally MHD does this in situations where the operation is likely to succeed, in which case performance is improved. Setting the flag should generally be safe (even though the code is slightly more experimental). You may want to benchmark your application to see if this makes any difference for you. @item MHD_USE_SUPPRESS_DATE_NO_CLOCK @cindex date @cindex clock @cindex embedded systems Suppress (automatically) adding the 'Date:' header to HTTP responses. This option should ONLY be used on systems that do not have a clock and that DO provide other mechanisms for cache control. See also RFC 2616, section 14.18 (exception 3). @item MHD_USE_NO_LISTEN_SOCKET @cindex listen @cindex proxy @cindex embedded systems Run the HTTP server without any listen socket. This option only makes sense if @code{MHD_add_connection} is going to be used exclusively to connect HTTP clients to the HTTP server. This option is incompatible with using a thread pool; if it is used, @code{MHD_OPTION_THREAD_POOL_SIZE} is ignored. @item MHD_USE_ITC @cindex quiesce Force MHD to use a signal inter-thread communication channel to notify the event loop (of threads) of our shutdown and other events. This is required if an application uses @code{MHD_USE_INTERNAL_POLLING_THREAD} and then performs @code{MHD_quiesce_daemon} (which eliminates our ability to signal termination via the listen socket). In these modes, @code{MHD_quiesce_daemon} will fail if this option was not set. Also, use of this option is automatic (as in, you do not even have to specify it), if @code{MHD_USE_NO_LISTEN_SOCKET} is specified. In "external" select mode, this option is always simply ignored. Using this option also guarantees that MHD will not call @code{shutdown()} on the listen socket, which means a parent process can continue to use the socket. @item MHD_ALLOW_SUSPEND_RESUME Enables using @code{MHD_suspend_connection} and @code{MHD_resume_connection}, as performing these calls requires some additional inter-thred communication channels to be created, and code not using these calls should not pay the cost. @item MHD_USE_TCP_FASTOPEN @cindex listen Enable TCP_FASTOPEN on the listen socket. TCP_FASTOPEN is currently supported on Linux >= 3.6. On other systems using this option with cause @code{MHD_start_daemon} to fail. @item MHD_ALLOW_UPGRADE @cindex upgrade This option must be set if you want to upgrade connections (via ``101 Switching Protocols'' responses). This requires MHD to allocate additional resources, and hence we require this special flag so we only use the resources that are really needed. @item MHD_USE_AUTO Automatically select best event loop style (polling function) depending on requested mode by other MHD flags and functions available on platform. If application doesn't have requirements for any specific polling function, it's recommended to use this flag. This flag is very convenient for multiplatform applications. @item MHD_USE_POST_HANDSHAKE_AUTH_SUPPORT Tell the TLS library to support post handshake client authentication. Only useful in combination with @code{MHD_USE_TLS}. This option will only work if the underlying TLS library supports it (i.e. GnuTLS after 3.6.3). If the TLS library does not support it, MHD may ignore the option and proceed without supporting this features. @item MHD_USE_INSECURE_TLS_EARLY_DATA Tell the TLS library to support TLS v1.3 early data (0-RTT) with the resulting security drawbacks. Only enable this if you really know what you are doing. MHD currently does NOT enforce that this only affects GET requests! You have been warned. This option will only work if the underlying TLS library supports it (i.e. GnuTLS after 3.6.3). If the TLS library does not support it, MHD may ignore the option and proceed without supporting this features. @end table @end deftp @deftp {Enumeration} MHD_OPTION MHD options. Passed in the varargs portion of @code{MHD_start_daemon()}. @table @code @item MHD_OPTION_END No more options / last option. This is used to terminate the VARARGs list. @item MHD_OPTION_CONNECTION_MEMORY_LIMIT @cindex memory, limiting memory utilization Maximum memory size per connection (followed by a @code{size_t}). The default is 32 kB (32*1024 bytes) as defined by the internal constant @code{MHD_POOL_SIZE_DEFAULT}. Values above 128k are unlikely to result in much benefit, as half of the memory will be typically used for IO, and TCP buffers are unlikely to support window sizes above 64k on most systems. @item MHD_OPTION_CONNECTION_MEMORY_INCREMENT @cindex memory Increment to use for growing the read buffer (followed by a @code{size_t}). The default is 1024 (bytes). Increasing this value will make MHD use memory for reading more aggressively, which can reduce the number of @code{recvfrom} calls but may increase the number of @code{sendto} calls. The given value must fit within MHD_OPTION_CONNECTION_MEMORY_LIMIT. @item MHD_OPTION_CONNECTION_LIMIT @cindex connection, limiting number of connections Maximum number of concurrent connections to accept (followed by an @code{unsigned int}). The default is @code{FD_SETSIZE - 4} (the maximum number of file descriptors supported by @code{select} minus four for @code{stdin}, @code{stdout}, @code{stderr} and the server socket). In other words, the default is as large as possible. If the connection limit is reached, MHD's behavior depends a bit on other options. If @code{MHD_USE_ITC} was given, MHD will stop accepting connections on the listen socket. This will cause the operating system to queue connections (up to the @code{listen()} limit) above the connection limit. Those connections will be held until MHD is done processing at least one of the active connections. If @code{MHD_USE_ITC} is not set, then MHD will continue to @code{accept()} and immediately @code{close()} these connections. Note that if you set a low connection limit, you can easily get into trouble with browsers doing request pipelining. For example, if your connection limit is ``1'', a browser may open a first connection to access your ``index.html'' file, keep it open but use a second connection to retrieve CSS files, images and the like. In fact, modern browsers are typically by default configured for up to 15 parallel connections to a single server. If this happens, MHD will refuse to even accept the second connection until the first connection is closed --- which does not happen until timeout. As a result, the browser will fail to render the page and seem to hang. If you expect your server to operate close to the connection limit, you should first consider using a lower timeout value and also possibly add a ``Connection: close'' header to your response to ensure that request pipelining is not used and connections are closed immediately after the request has completed: @example MHD_add_response_header (response, MHD_HTTP_HEADER_CONNECTION, "close"); @end example @item MHD_OPTION_CONNECTION_TIMEOUT @cindex timeout After how many seconds of inactivity should a connection automatically be timed out? (followed by an @code{unsigned int}; use zero for no timeout). The default is zero (no timeout). @item MHD_OPTION_NOTIFY_COMPLETED Register a function that should be called whenever a request has been completed (this can be used for application-specific clean up). Requests that have never been presented to the application (via @code{MHD_AccessHandlerCallback()}) will not result in notifications. This option should be followed by @strong{TWO} pointers. First a pointer to a function of type @code{MHD_RequestCompletedCallback()} and second a pointer to a closure to pass to the request completed callback. The second pointer maybe @code{NULL}. @item MHD_OPTION_NOTIFY_CONNECTION Register a function that should be called when the TCP connection to a client is opened or closed. The registered callback is called twice per TCP connection, with @code{MHD_CONNECTION_NOTIFY_STARTED} and @code{MHD_CONNECTION_NOTIFY_CLOSED} respectively. An additional argument can be used to store TCP connection specific information, which can be retrieved using @code{MHD_CONNECTION_INFO_SOCKET_CONTEXT} during the lifetime of the TCP connection. Note @code{MHD_OPTION_NOTIFY_COMPLETED} and the @code{req_cls} argument to the @code{MHD_AccessHandlerCallback} are per HTTP request (and there can be multiple HTTP requests per TCP connection). This option should be followed by @strong{TWO} pointers. First a pointer to a function of type @code{MHD_NotifyConnectionCallback()} and second a pointer to a closure to pass to the request completed callback. The second pointer maybe @code{NULL}. @item MHD_OPTION_PER_IP_CONNECTION_LIMIT Limit on the number of (concurrent) connections made to the server from the same IP address. Can be used to prevent one IP from taking over all of the allowed connections. If the same IP tries to establish more than the specified number of connections, they will be immediately rejected. The option should be followed by an @code{unsigned int}. The default is zero, which means no limit on the number of connections from the same IP address. @item MHD_OPTION_LISTEN_BACKLOG_SIZE Set the size of the @code{listen()} back log queue of the TCP socket. Takes an @code{unsigned int} as the argument. Default is the platform-specific value of @code{SOMAXCONN}. @item MHD_OPTION_STRICT_FOR_CLIENT Specify how strict we should enforce the HTTP protocol. Takes an @code{int} as the argument. Default is zero. If set to 1, MHD will be strict about the protocol. Specifically, at the moment, this flag uses MHD to reject HTTP 1.1 connections without a "Host" header. This is required by the standard, but of course in violation of the "be as liberal as possible in what you accept" norm. It is recommended to set this to 1 if you are testing clients against MHD, and 0 in production. If set to -1 MHD will be permissive about the protocol, allowing slight deviations that are technically not allowed by the RFC. Specifically, at the moment, this flag causes MHD to allow spaces in header field names. This is disallowed by the standard. It is not recommended to set it to -1 on publicly available servers as it may potentially lower level of protection. @item MHD_OPTION_SERVER_INSANITY @cindex testing Allows the application to disable certain sanity precautions in MHD. With these, the client can break the HTTP protocol, so this should never be used in production. The options are, however, useful for testing HTTP clients against "broken" server implementations. This argument must be followed by an @code{unsigned int}, corresponding to an @code{enum MHD_DisableSanityCheck}. Right now, no sanity checks can be disabled. @item MHD_OPTION_SOCK_ADDR @cindex bind, restricting bind Bind daemon to the supplied socket address. This option should be followed by a @code{struct sockaddr *}. If @code{MHD_USE_IPv6} is specified, the @code{struct sockaddr*} should point to a @code{struct sockaddr_in6}, otherwise to a @code{struct sockaddr_in}. If this option is not specified, the daemon will listen to incoming connections from anywhere. If you use this option, the 'port' argument from @code{MHD_start_daemon} is ignored and the port from the given @code{struct sockaddr *} will be used instead. @item MHD_OPTION_URI_LOG_CALLBACK @cindex debugging @cindex logging @cindex query string Specify a function that should be called before parsing the URI from the client. The specified callback function can be used for processing the URI (including the options) before it is parsed. The URI after parsing will no longer contain the options, which maybe inconvenient for logging. This option should be followed by two arguments, the first one must be of the form @example void * my_logger(void * cls, const char * uri, struct MHD_Connection *con) @end example where the return value will be passed as @code{*req_cls} in calls to the @code{MHD_AccessHandlerCallback} when this request is processed later; returning a value of @code{NULL} has no special significance; (however, note that if you return non-@code{NULL}, you can no longer rely on the first call to the access handler having @code{NULL == *req_cls} on entry) @code{cls} will be set to the second argument following MHD_OPTION_URI_LOG_CALLBACK. Finally, @code{uri} will be the 0-terminated URI of the request. Note that during the time of this call, most of the connection's state is not initialized (as we have not yet parsed he headers). However, information about the connecting client (IP, socket) is available. @item MHD_OPTION_HTTPS_MEM_KEY @cindex SSL @cindex TLS Memory pointer to the private key to be used by the HTTPS daemon. This option should be followed by an "const char*" argument. This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_CERT'. @item MHD_OPTION_HTTPS_KEY_PASSWORD @cindex SSL @cindex TLS Memory pointer to the password that decrypts the private key to be used by the HTTPS daemon. This option should be followed by an "const char*" argument. This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_KEY'. The password (or passphrase) is only used immediately during @code{MHD_start_daemon()}. Thus, the application may want to erase it from memory afterwards for additional security. @item MHD_OPTION_HTTPS_MEM_CERT @cindex SSL @cindex TLS Memory pointer to the certificate to be used by the HTTPS daemon. This option should be followed by an "const char*" argument. This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_KEY'. @item MHD_OPTION_HTTPS_MEM_TRUST @cindex SSL @cindex TLS Memory pointer to the CA certificate to be used by the HTTPS daemon to authenticate and trust clients certificates. This option should be followed by an "const char*" argument. The presence of this option activates the request of certificate to the client. The request to the client is marked optional, and it is the responsibility of the server to check the presence of the certificate if needed. Note that most browsers will only present a client certificate only if they have one matching the specified CA, not sending any certificate otherwise. @item MHD_OPTION_HTTPS_CRED_TYPE @cindex SSL @cindex TLS Daemon credentials type. Either certificate or anonymous, this option should be followed by one of the values listed in "enum gnutls_credentials_type_t". @item MHD_OPTION_HTTPS_PRIORITIES @cindex SSL @cindex TLS @cindex cipher SSL/TLS protocol version and ciphers. This option must be followed by an "const char *" argument specifying the SSL/TLS protocol versions and ciphers that are acceptable for the application. The string is passed unchanged to gnutls_priority_init. If this option is not specified, ``NORMAL'' is used. @item MHD_OPTION_HTTPS_CERT_CALLBACK @cindex SSL @cindex TLS @cindex SNI Use a callback to determine which X.509 certificate should be used for a given HTTPS connection. This option should be followed by a argument of type "gnutls_certificate_retrieve_function2 *". This option provides an alternative to MHD_OPTION_HTTPS_MEM_KEY and MHD_OPTION_HTTPS_MEM_CERT. You must use this version if multiple domains are to be hosted at the same IP address using TLS's Server Name Indication (SNI) extension. In this case, the callback is expected to select the correct certificate based on the SNI information provided. The callback is expected to access the SNI data using gnutls_server_name_get(). Using this option requires GnuTLS 3.0 or higher. @item MHD_OPTION_HTTPS_CERT_CALLBACK2 @cindex SSL @cindex TLS @cindex SNI @cindex OCSP Use a callback to determine which X.509 certificate should be used for a given HTTPS connection. This option should be followed by a argument of type `gnutls_certificate_retrieve_function3 *`. This option provides an alternative/extension to #MHD_OPTION_HTTPS_CERT_CALLBACK. You must use this version if you want to use OCSP stapling. Using this option requires GnuTLS 3.6.3 or higher. @item MHD_OPTION_GNUTLS_PSK_CRED_HANDLER @cindex SSL @cindex TLS @cindex PSK Use pre-shared key for TLS credentials. Pass a pointer to callback of type @code{MHD_PskServerCredentialsCallback} and a closure. The function will be called to retrieve the shared key for a given username. @item MHD_OPTION_DIGEST_AUTH_RANDOM @cindex digest auth @cindex random Digest Authentication nonce's seed. This option should be followed by two arguments. First an integer of type "size_t" which specifies the size of the buffer pointed to by the second argument in bytes. Note that the application must ensure that the buffer of the second argument remains allocated and unmodified while the daemon is running. For security, you SHOULD provide a fresh random nonce when using MHD with Digest Authentication. @item MHD_OPTION_NONCE_NC_SIZE @cindex digest auth @cindex replay attack Size of an array of nonce and nonce counter map. This option must be followed by an "unsigned int" argument that have the size (number of elements) of a map of a nonce and a nonce-counter. If this option is not specified, a default value of 4 will be used (which might be too small for servers handling many requests). If you do not use digest authentication at all, you can specify a value of zero to save some memory. You should calculate the value of NC_SIZE based on the number of connections per second multiplied by your expected session duration plus a factor of about two for hash table collisions. For example, if you expect 100 digest-authenticated connections per second and the average user to stay on your site for 5 minutes, then you likely need a value of about 60000. On the other hand, if you can only expect only 10 digest-authenticated connections per second, tolerate browsers getting a fresh nonce for each request and expect a HTTP request latency of 250 ms, then a value of about 5 should be fine. @item MHD_OPTION_LISTEN_SOCKET @cindex systemd Listen socket to use. Pass a listen socket for MHD to use (systemd-style). If this option is used, MHD will not open its own listen socket(s). The argument passed must be of type "int" and refer to an existing socket that has been bound to a port and is listening. @item MHD_OPTION_EXTERNAL_LOGGER @cindex logging Use the given function for logging error messages. This option must be followed by two arguments; the first must be a pointer to a function of type 'void fun(void * arg, const char * fmt, va_list ap)' and the second a pointer of type 'void*' which will be passed as the "arg" argument to "fun". Note that MHD will not generate any log messages without the MHD_USE_ERROR_LOG flag set and if MHD was compiled with the "--disable-messages" flag. @item MHD_OPTION_THREAD_POOL_SIZE @cindex performance Number (unsigned int) of threads in thread pool. Enable thread pooling by setting this value to to something greater than 1. Currently, thread mode must be MHD_USE_INTERNAL_POLLING_THREAD if thread pooling is enabled (@code{MHD_start_daemon} returns @code{NULL} for an unsupported thread mode). @item MHD_OPTION_ARRAY @cindex options @cindex foreign-function interface This option can be used for initializing MHD using options from an array. A common use for this is writing an FFI for MHD. The actual options given are in an array of 'struct MHD_OptionItem', so this option requires a single argument of type 'struct MHD_OptionItem'. The array must be terminated with an entry @code{MHD_OPTION_END}. An example for code using MHD_OPTION_ARRAY is: @example struct MHD_OptionItem ops[] = @{ @{ MHD_OPTION_CONNECTION_LIMIT, 100, NULL @}, @{ MHD_OPTION_CONNECTION_TIMEOUT, 10, NULL @}, @{ MHD_OPTION_END, 0, NULL @} @}; d = MHD_start_daemon(0, 8080, NULL, NULL, dh, NULL, MHD_OPTION_ARRAY, ops, MHD_OPTION_END); @end example For options that expect a single pointer argument, the second member of the @code{struct MHD_OptionItem} is ignored. For options that expect two pointer arguments, the first argument must be cast to @code{intptr_t}. @item MHD_OPTION_UNESCAPE_CALLBACK @cindex internationalization @cindex escaping Specify a function that should be called for unescaping escape sequences in URIs and URI arguments. Note that this function will NOT be used by the MHD_PostProcessor. If this option is not specified, the default method will be used which decodes escape sequences of the form "%HH". This option should be followed by two arguments, the first one must be of the form @example size_t my_unescaper(void * cls, struct MHD_Connection *c, char *s) @end example where the return value must be @code{strlen(s)} and @code{s} should be updated. Note that the unescape function must not lengthen @code{s} (the result must be shorter than the input and still be 0-terminated). @code{cls} will be set to the second argument following MHD_OPTION_UNESCAPE_CALLBACK. @item MHD_OPTION_THREAD_STACK_SIZE @cindex stack @cindex thread @cindex pthread @cindex embedded systems Maximum stack size for threads created by MHD. This option must be followed by a @code{size_t}). Not specifying this option or using a value of zero means using the system default (which is likely to differ based on your platform). @item MHD_OPTION_TCP_FASTQUEUE_QUEUE_SIZE @cindex listen When the flag @code{MHD_USE_TCP_FASTOPEN} is used, this option sets the connection handshake queue size for the TCP FASTOPEN connections. Note that a TCP FASTOPEN connection handshake occupies more resources than a TCP handshake as the SYN packets also contain DATA which is kept in the associate state until handshake is completed. If this option is not given the queue size is set to a default value of 10. This option must be followed by a @code{unsigned int}. @item MHD_OPTION_HTTPS_MEM_DHPARAMS @cindex TLS @cindex SSL @cindex DH Memory pointer for the Diffie-Hellman parameters (dh.pem) to be used by the HTTPS daemon for key exchange.

If this option is present and true (nonzero) parameter is given, allow reusing the address:port of the listening socket (using @code{SO_REUSEPORT} on most platforms, and @code{SO_REUSEADDR} on Windows). If a false (zero) parameter is given, disallow reusing the the address:port of the listening socket (this usually requires no special action, but @code{SO_EXCLUSIVEADDRUSE} is needed on Windows). If this option is not present @code{SO_REUSEADDR} is used on all platforms except Windows so reusing of address:port is disallowed. @end table @end deftp @deftp {C Struct} MHD_OptionItem Entry in an MHD_OPTION_ARRAY.

Note that for options taking only a single pointer, the @code{ptr_value} member should be set. For options taking two pointer arguments, the first pointer must be cast to @code{intptr_t} and both the @code{value} and the @code{ptr_value} members should be used to pass the two pointers. @end deftp @deftp {Enumeration} MHD_ValueKind The @code{MHD_ValueKind} specifies the source of the key-value pairs in the HTTP protocol. @table @code @item MHD_HEADER_KIND HTTP header. @item MHD_COOKIE_KIND @cindex cookie Cookies.

MHD must make its own private copy of the data for processing. @end table @end deftp @deftp {Enumeration} MHD_ResponseFlags Response-specific flags. Passed as an argument to @code{MHD_set_response_options()}. @table @code @item MHD_RF_NONE No special handling. @item MHD_RF_HTTP_VERSION_1_0_ONLY Only respond in conservative HTTP 1.0-mode. In particular, do not (automatically) sent "Connection" headers and always close the connection after generating the response. By default, MHD will respond using the same HTTP version which was set in the request. You can also set the @code{MHD_RF_HTTP_VERSION_1_0_RESPONSE} flag to force version 1.0 in the response. @item MHD_RF_HTTP_VERSION_1_0_RESPONSE Only respond in HTTP 1.0-mode. Contrary to the @code{MHD_RF_HTTP_VERSION_1_0_ONLY} flag, the response's HTTP version will always be set to 1.0 and ``Connection'' headers are still supported. You can even combine this option with MHD_RF_HTTP_VERSION_1_0_ONLY to change the response's HTTP version while maintaining strict compliance with HTTP 1.0 regarding connection management. This solution is not perfect as this flag is set on the response which is created after header processing. So MHD will behave as a HTTP 1.1 server until the response is queued. It means that an invalid HTTP 1.1 request will fail even if the response is sent with HTTP 1.0 and the request would be valid if interpreted with this version. For example, this request will fail in strict mode: @verbatim GET / HTTP/1.1 @end verbatim as the ``Host'' header is missing and is mandatory in HTTP 1.1, but it should succeed when interpreted with HTTP 1.0. @item MHD_RF_INSANITY_HEADER_CONTENT_LENGTH Disable sanity check preventing clients from manually setting the HTTP content length option. @end table @end deftp @deftp {Enumeration} MHD_ResponseOptions Response-specific options.

This is used for initialization of a websocket stream when calling @code{MHD_websocket_stream_init} or @code{MHD_websocket_stream_init2} and alters the behavior of the websocket stream. Note that websocket streams are only available if you include the header file @code{microhttpd_ws.h} and compiled @emph{libmicrohttpd} with websockets. @table @code @item MHD_WEBSOCKET_FLAG_SERVER The websocket stream is initialized in server mode (default). Thus all outgoing payload will not be masked. All incoming payload must be masked. This flag cannot be used together with @code{MHD_WEBSOCKET_FLAG_CLIENT}. @item MHD_WEBSOCKET_FLAG_CLIENT The websocket stream is initialized in client mode. You will usually never use that mode in combination with @emph{libmicrohttpd}, because @emph{libmicrohttpd} provides a server and not a client. In client mode all outgoing payload will be masked (XOR-ed with random values). All incoming payload must be unmasked. If you use this mode, you must always call @code{MHD_websocket_stream_init2} instead of @code{MHD_websocket_stream_init}, because you need to pass a random number generator callback function for masking. This flag cannot be used together with @code{MHD_WEBSOCKET_FLAG_SERVER}. @item MHD_WEBSOCKET_FLAG_NO_FRAGMENTS You don't want to get fragmented data while decoding (default). Fragmented frames will be internally put together until they are complete. Whether or not data is fragmented is decided by the sender of the data during encoding. This cannot be used together with @code{MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS}. @item MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS You want fragmented data, if it appears while decoding. You will receive the content of the fragmented frame, but if you are decoding text, you will never get an unfinished UTF-8 sequence (if the sequence appears between two fragments). Instead the text will end before the unfinished UTF-8 sequence. With the next fragment, which finishes the UTF-8 sequence, you will get the complete UTF-8 sequence. This cannot be used together with @code{MHD_WEBSOCKET_FLAG_NO_FRAGMENTS}. @item MHD_WEBSOCKET_FLAG_GENERATE_CLOSE_FRAMES_ON_ERROR If the websocket stream becomes invalid during decoding due to protocol errors, a matching close frame will automatically be generated. The close frame will be returned via the parameters @code{payload} and @code{payload_len} of @code{MHD_websocket_decode} and the return value is negative (a value of @code{enum MHD_WEBSOCKET_STATUS}). The generated close frame must be freed by the caller with @code{MHD_websocket_free}. @end table @end deftp @deftp {Enumeration} MHD_WEBSOCKET_FRAGMENTATION @cindex websocket This enumeration is used to specify the fragmentation behavior when encoding of data (text/binary) for a websocket stream. This is used with @code{MHD_websocket_encode_text} or @code{MHD_websocket_encode_binary}. Note that websocket streams are only available if you include the header file @code{microhttpd_ws.h} and compiled @emph{libmicrohttpd} with websockets. @table @code @item MHD_WEBSOCKET_FRAGMENTATION_NONE You don't want to use fragmentation. The encoded frame consists of only one frame. @item MHD_WEBSOCKET_FRAGMENTATION_FIRST You want to use fragmentation. The encoded frame is the first frame of a series of data frames of the same type (text or binary). You may send control frames (ping, pong or close) between these data frames. @item MHD_WEBSOCKET_FRAGMENTATION_FOLLOWING You want to use fragmentation. The encoded frame is not the first frame of the series of data frames, but also not the last one. You may send control frames (ping, pong or close) between these data frames. @item MHD_WEBSOCKET_FRAGMENTATION_LAST You want to use fragmentation. The encoded frame is the last frame of the series of data frames, but also not the first one. After this frame, you may send all types of frames again. @end table @end deftp @deftp {Enumeration} MHD_WEBSOCKET_STATUS @cindex websocket This enumeration is used for the return value of almost every websocket stream function. Errors are negative and values equal to or above zero mean a success. Positive values are only used by @code{MHD_websocket_decode}. Note that websocket streams are only available if you include the header file @code{microhttpd_ws.h} and compiled @emph{libmicrohttpd} with websockets. @table @code @item MHD_WEBSOCKET_STATUS_OK The call succeeded. Especially for @code{MHD_websocket_decode} this means that no error occurred, but also no frame has been completed yet. For other functions this means simply a success. @item MHD_WEBSOCKET_STATUS_TEXT_FRAME @code{MHD_websocket_decode} has decoded a text frame. The parameters @code{payload} and @code{payload_len} are filled with the decoded text (if any). You must free the returned @code{payload} after use with @code{MHD_websocket_free}. @item MHD_WEBSOCKET_STATUS_BINARY_FRAME @code{MHD_websocket_decode} has decoded a binary frame. The parameters @code{payload} and @code{payload_len} are filled with the decoded binary data (if any). You must free the returned @code{payload} after use with @code{MHD_websocket_free}. @item MHD_WEBSOCKET_STATUS_CLOSE_FRAME @code{MHD_websocket_decode} has decoded a close frame. This means you must close the socket using @code{MHD_upgrade_action} with @code{MHD_UPGRADE_ACTION_CLOSE}. You may respond with a close frame before closing. The parameters @code{payload} and @code{payload_len} are filled with the close reason (if any). The close reason starts with a two byte sequence of close code in network byte order (see @code{enum MHD_WEBSOCKET_CLOSEREASON}). After these two bytes a UTF-8 encoded close reason may follow. You can call @code{MHD_websocket_split_close_reason} to split that close reason. You must free the returned @code{payload} after use with @code{MHD_websocket_free}. @item MHD_WEBSOCKET_STATUS_PING_FRAME @code{MHD_websocket_decode} has decoded a ping frame. You should respond to this with a pong frame. The pong frame must contain the same binary data as the corresponding ping frame (if it had any). The parameters @code{payload} and @code{payload_len} are filled with the binary ping data (if any). You must free the returned @code{payload} after use with @code{MHD_websocket_free}. @item MHD_WEBSOCKET_STATUS_PONG_FRAME @code{MHD_websocket_decode} has decoded a pong frame. You should usually only receive pong frames if you sent a ping frame before. The binary data should be equal to your ping frame and can be used to distinguish the response if you sent multiple ping frames. The parameters @code{payload} and @code{payload_len} are filled with the binary pong data (if any). You must free the returned @code{payload} after use with @code{MHD_websocket_free}. @item MHD_WEBSOCKET_STATUS_TEXT_FIRST_FRAGMENT @code{MHD_websocket_decode} has decoded a text frame fragment. The parameters @code{payload} and @code{payload_len} are filled with the decoded text (if any). This is like @code{MHD_WEBSOCKET_STATUS_TEXT_FRAME}, but it can only appear if you specified @code{MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS} during the call of @code{MHD_websocket_stream_init} or @code{MHD_websocket_stream_init2}. You must free the returned @code{payload} after use with @code{MHD_websocket_free}. @item MHD_WEBSOCKET_STATUS_TEXT_FIRST_FRAGMENT @code{MHD_websocket_decode} has decoded a binary frame fragment. The parameters @code{payload} and @code{payload_len} are filled with the decoded binary data (if any).

You must free the returned @code{payload} after use with @code{MHD_websocket_free}. @item MHD_WEBSOCKET_STATUS_TEXT_NEXT_FRAGMENT @code{MHD_websocket_decode} has decoded the next text frame fragment. The parameters @code{payload} and @code{payload_len} are filled with the decoded text (if any). This is like @code{MHD_WEBSOCKET_STATUS_TEXT_FIRST_FRAGMENT}, but it appears only after the first and before the last fragment of a series of fragments. It can only appear if you specified @code{MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS} during the call of @code{MHD_websocket_stream_init} or @code{MHD_websocket_stream_init2}. You must free the returned @code{payload} after use with @code{MHD_websocket_free}. @item MHD_WEBSOCKET_STATUS_BINARY_NEXT_FRAGMENT @code{MHD_websocket_decode} has decoded the next binary frame fragment. The parameters @code{payload} and @code{payload_len} are filled with the decoded binary data (if any). This is like @code{MHD_WEBSOCKET_STATUS_BINARY_FIRST_FRAGMENT}, but it appears only after the first and before the last fragment of a series of fragments. It can only appear if you specified @code{MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS} during the call of @code{MHD_websocket_stream_init} or @code{MHD_websocket_stream_init2}. You must free the returned @code{payload} after use with @code{MHD_websocket_free}. @item MHD_WEBSOCKET_STATUS_TEXT_LAST_FRAGMENT @code{MHD_websocket_decode} has decoded the last text frame fragment. The parameters @code{payload} and @code{payload_len} are filled with the decoded text (if any). This is like @code{MHD_WEBSOCKET_STATUS_TEXT_FIRST_FRAGMENT}, but it appears only for the last fragment of a series of fragments. It can only appear if you specified @code{MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS} during the call of @code{MHD_websocket_stream_init} or @code{MHD_websocket_stream_init2}. You must free the returned @code{payload} after use with @code{MHD_websocket_free}. @item MHD_WEBSOCKET_STATUS_BINARY_LAST_FRAGMENT @code{MHD_websocket_decode} has decoded the last binary frame fragment. The parameters @code{payload} and @code{payload_len} are filled with the decoded binary data (if any). This is like @code{MHD_WEBSOCKET_STATUS_BINARY_FIRST_FRAGMENT}, but it appears only for the last fragment of a series of fragments. It can only appear if you specified @code{MHD_WEBSOCKET_FLAG_WANT_FRAGMENTS} during the call of @code{MHD_websocket_stream_init} or @code{MHD_websocket_stream_init2}. You must free the returned @code{payload} after use with @code{MHD_websocket_free}. @item MHD_WEBSOCKET_STATUS_PROTOCOL_ERROR The call failed and the stream is invalid now for decoding. You must close the websocket now using @code{MHD_upgrade_action} with @code{MHD_UPGRADE_ACTION_CLOSE}. You may send a close frame before closing. This is only used by @code{MHD_websocket_decode} and happens if the stream contains errors (i. e. invalid byte data). @item MHD_WEBSOCKET_STATUS_STREAM_BROKEN You tried to decode something, but the stream has already been marked invalid. You must close the websocket now using @code{MHD_upgrade_action} with @code{MHD_UPGRADE_ACTION_CLOSE}. You may send a close frame before closing.

You can call @code{MHD_websocket_stream_is_valid} at any time to check whether a stream is invalid or not. @item MHD_WEBSOCKET_STATUS_MEMORY_ERROR A memory allocation failed. The stream remains valid. If this occurred while decoding, the decoding could be possible later if enough memory is available. This could happen while decoding if you received a too big data frame. You could try to specify max_payload_size during the call of @code{MHD_websocket_stream_init} or @code{MHD_websocket_stream_init2} to avoid this and close the websocket instead. @item MHD_WEBSOCKET_STATUS_PARAMETER_ERROR You passed invalid parameters during the function call (i. e. a NULL pointer for a required parameter). The stream remains valid. @item MHD_WEBSOCKET_STATUS_MAXIMUM_SIZE_EXCEEDED The maximum payload size has been exceeded. If you got this return code from @code{MHD_websocket_decode} then the stream becomes invalid and the websocket must be closed using @code{MHD_upgrade_action} with @code{MHD_UPGRADE_ACTION_CLOSE}. You may send a close frame before closing. The maximum payload size is specified during the call of @code{MHD_websocket_stream_init} or @code{MHD_websocket_stream_init2}. This can also appear if you specified 0 as maximum payload size when the message is greater than the maximum allocatable memory size (i. e. more than 4 GiB on 32 bit systems). If you got this return code from @code{MHD_websocket_encode_close}, @code{MHD_websocket_encode_ping} or @code{MHD_websocket_encode_pong} then you passed to much payload data. The stream remains valid then. @item MHD_WEBSOCKET_STATUS_UTF8_ENCODING_ERROR An UTF-8 sequence is invalid. If you got this return code from @code{MHD_websocket_decode} then the stream becomes invalid and you must close the websocket using @code{MHD_upgrade_action} with @code{MHD_UPGRADE_ACTION_CLOSE}. You may send a close frame before closing. If you got this from @code{MHD_websocket_encode_text} or @code{MHD_websocket_encode_close} then you passed invalid UTF-8 text. The stream remains valid then. @item MHD_WEBSOCKET_STATUS_NO_WEBSOCKET_HANDSHAKE_HEADER A check routine for the HTTP headers came to the conclusion that the header value isn't valid for a websocket handshake request. This value can only be returned from the following functions: @code{MHD_websocket_check_http_version}, @code{MHD_websocket_check_connection_header}, @code{MHD_websocket_check_upgrade_header}, @code{MHD_websocket_check_version_header}, @code{MHD_websocket_create_accept_header} @end table @end deftp @deftp {Enumeration} MHD_WEBSOCKET_CLOSEREASON @cindex websocket Enumeration of possible close reasons for websocket close frames.

For example if you received a binary frame, but your application only expects text frames. @item MHD_WEBSOCKET_CLOSEREASON_MALFORMED_UTF8 You close the websocket because it contains malformed UTF-8. The UTF-8 validity is automatically checked by @code{MHD_websocket_decode}, so you don't need to check it on your own.

If supported by the client and the HTTP version, the application can at this point queue an error response to possibly avoid the upload entirely. If no response is generated, MHD will (if required) automatically send a 100 CONTINUE reply to the client. Afterwards, POST data will be passed to the callback to be processed incrementally by the application. The application may return @code{MHD_NO} to forcefully terminate the TCP connection without generating a proper HTTP response.

In order to avoid this, clients must be able to process upload data incrementally and reduce the value of @code{upload_data_size}. @item req_cls reference to a pointer, initially set to @code{NULL}, that this callback can set to some address and that will be preserved by MHD for future calls for this request; since the access handler may be called many times (i.e., for a @code{PUT}/@code{POST} operation with plenty of upload data) this allows the application to easily associate some request-specific state; if necessary, this state can be cleaned up in the global @code{MHD_RequestCompletedCallback} (which can be set with the @code{MHD_OPTION_NOTIFY_COMPLETED}). @end table @end deftypefn @deftypefn {Function Pointer} void {*MHD_RequestCompletedCallback} (void *cls, struct MHD_Connectionconnection, void **req_cls, enum MHD_RequestTerminationCode toe) Signature of the callback used by MHD to notify the application about completed requests. @table @var @item cls custom value selected at callback registration time; @item connection connection handle; @item req_cls value as set by the last call to the @code{MHD_AccessHandlerCallback}; @item toe reason for request termination see @code{MHD_OPTION_NOTIFY_COMPLETED}. @end table @end deftypefn @deftypefn {Function Pointer} enum MHD_Result {*MHD_KeyValueIterator} (void *cls, enum MHD_ValueKind kind, const char *key, const char *value, size_t value_size) Iterator over key-value pairs.

This argument was introduced in @code{MHD_VERSION} 0x00096301 to allow applications to use binary zeros in values. Applications using this argument must ensure that they are using a sufficiently recent version of MHD, i.e. by testing @code{MHD_get_version()} for values above or equal to 0.9.64. Applications that do not need zeros in values and that want to compile without warnings against newer versions of MHD should not declare this argument and cast the function pointer argument to @code{MHD_KeyValueIterator}. @end table Return @code{MHD_YES} to continue iterating, @code{MHD_NO} to abort the iteration. @end deftypefn @deftypefn {Function Pointer} ssize_t {*MHD_ContentReaderCallback} (void *cls, uint64_t pos, char *buf, size_t max) Callback used by MHD in order to obtain content. The callback has to copy at most @var{max} bytes of content into @var{buf}. The total number of bytes that has been placed into @var{buf} should be returned. Note that returning zero will cause MHD to try again. Thus, returning zero should only be used in conjunction with @code{MHD_suspend_connection()} to avoid busy waiting. While usually the callback simply returns the number of bytes written into @var{buf}, there are two special return value: @code{MHD_CONTENT_READER_END_OF_STREAM} (-1) should be returned for the regular end of transmission (with chunked encoding, MHD will then terminate the chunk and send any HTTP footers that might be present; without chunked encoding and given an unknown response size, MHD will simply close the connection; note that while returning @code{MHD_CONTENT_READER_END_OF_STREAM} is not technically legal if a response size was specified, MHD accepts this and treats it just as @code{MHD_CONTENT_READER_END_WITH_ERROR}. @code{MHD_CONTENT_READER_END_WITH_ERROR} (-2) is used to indicate a server error generating the response; this will cause MHD to simply close the connection immediately. If a response size was given or if chunked encoding is in use, this will indicate an error to the client. Note, however, that if the client does not know a response size and chunked encoding is not in use, then clients will not be able to tell the difference between @code{MHD_CONTENT_READER_END_WITH_ERROR} and @code{MHD_CONTENT_READER_END_OF_STREAM}. This is not a limitation of MHD but rather of the HTTP protocol. @table @var @item cls custom value selected at callback registration time; @item pos position in the datastream to access; note that if an @code{MHD_Response} object is re-used, it is possible for the same content reader to be queried multiple times for the same data; however, if an @code{MHD_Response} is not re-used, MHD guarantees that @var{pos} will be the sum of all non-negative return values obtained from the content reader so far. @end table Return @code{-1} on error (MHD will no longer try to read content and instead close the connection with the client). @end deftypefn @deftypefn {Function Pointer} void {*MHD_ContentReaderFreeCallback} (void *cls) This method is called by MHD if we are done with a content reader.

Allows clients to continue processing, but stops accepting new connections. Note that the caller is responsible for closing the returned socket; however, if MHD is run using threads (anything but external select mode), it must not be closed until AFTER @code{MHD_stop_daemon} has been called (as it is theoretically possible that an existing thread is still using it). This function is useful in the special case that a listen socket is to be migrated to another process (i.e. a newer version of the HTTP server) while existing connections should continue to be processed until they are finished. Return @code{-1} on error (daemon not listening), the handle to the listen socket otherwise. @end deftypefun @deftypefun void MHD_stop_daemon (struct MHD_Daemon *daemon) Shutdown an HTTP daemon. @end deftypefun @deftypefun enum MHD_Result MHD_run (struct MHD_Daemon *daemon) Run webserver operations (without blocking unless in client callbacks).

You can use this function instead of @code{MHD_run} if you called @code{select} on the result from @code{MHD_get_fdset}. File descriptors in the sets that are not controlled by MHD will be ignored.

This API is usually not needed (since MHD will accept inbound connections on the server socket). Use this API in special cases, for example if your HTTP server is behind NAT and needs to connect out to the HTTP client, or if you are building a proxy. If you use this API in conjunction with a internal select or a thread pool, you must set the option @code{MHD_USE_ITC} to ensure that the freshly added connection is immediately processed by MHD.

The daemon's socket is added to @var{read_fd_set}. The list of currently existent connections is scanned and their file descriptors added to the correct set. When calling this function, FD_SETSIZE is assumed to be platform's default. If you changed FD_SETSIZE for your application, you should use @code{MHD_get_fdset2()} instead. This function should only be called in when MHD is configured to use external select with @code{select()} or with @code{epoll()}. In the latter case, it will only add the single @code{epoll()} file descriptor used by MHD to the sets. After the call completed successfully: the variable referenced by @var{max_fd} references the file descriptor with highest integer identifier. The variable must be set to zero before invoking this function.

The returned value is how many milliseconds @code{select} should at most block, not the timeout value set for connections. This function must not be called if the @code{MHD_USE_THREAD_PER_CONNECTION} mode is in use (since then it is not meaningful to ask for a timeout, after all, there is concurrenct activity). The function must also not be called by user-code if @code{MHD_USE_INTERNAL_POLLING_THREAD} is in use. In the latter case, the behavior is undefined. @table @var @item daemon which daemon to obtain the timeout from. @item timeout will be set to the timeout (in milliseconds). @end table Return @code{MHD_YES} on success, @code{MHD_NO} if timeouts are not used (or no connections exist that would necessitate the use of a timeout right now). @end deftypefun @c ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ @c ----------------------------------------------------------- @node microhttpd-requests @chapter Handling requests @deftypefun int MHD_get_connection_values (struct MHD_Connection *connection, enum MHD_ValueKind kind, MHD_KeyValueIterator iterator, void *iterator_cls) Get all the headers matching @var{kind} from the request. The @var{kind} argument can be a bitmask, ORing the various header kinds that are requested. The @var{iterator} callback is invoked once for each header, with @var{iterator_cls} as first argument. After version 0.9.19, the headers are iterated in the same order as they were received from the network; previous versions iterated over the headers in reverse order. @code{MHD_get_connection_values} returns the number of entries iterated over; this can be less than the number of headers if, while iterating, @var{iterator} returns @code{MHD_NO}. @var{iterator} can be @code{NULL}: in this case this function just counts and returns the number of headers. In the case of @code{MHD_GET_ARGUMENT_KIND}, the @var{value} argument will be @code{NULL} if the URL contained a key without an equals operator. For example, for a HTTP request to the URL ``http://foo/bar?key'', the @var{value} argument is @code{NULL}; in contrast, a HTTP request to the URL ``http://foo/bar?key='', the @var{value} argument is the empty string. The normal case is that the URL contains ``http://foo/bar?key=value'' in which case @var{value} would be the string ``value'' and @var{key} would contain the string ``key''. @end deftypefun @deftypefun enum MHD_Result MHD_set_connection_value (struct MHD_Connection *connection, enum MHD_ValueKind kind, const char *key, const char *value) This function can be used to append an entry to the list of HTTP headers of a connection (so that the @code{MHD_get_connection_values function} will return them -- and the MHD PostProcessor will also see them). This maybe required in certain situations (see Mantis #1399) where (broken) HTTP implementations fail to supply values needed by the post processor (or other parts of the application). This function MUST only be called from within the MHD_AccessHandlerCallback (otherwise, access maybe improperly synchronized). Furthermore, the client must guarantee that the key and value arguments are 0-terminated strings that are NOT freed until the connection is closed. (The easiest way to do this is by passing only arguments to permanently allocated strings.). @var{connection} is the connection for which the entry for @var{key} of the given @var{kind} should be set to the given @var{value}. The function returns @code{MHD_NO} if the operation could not be performed due to insufficient memory and @code{MHD_YES} on success. @end deftypefun @deftypefun {const char *} MHD_lookup_connection_value (struct MHD_Connection *connection, enum MHD_ValueKind kind, const char *key) Get a particular header value. If multiple values match the @var{kind}, return one of them (the ``first'', whatever that means). @var{key} must reference a zero-terminated ASCII-coded string representing the header to look for: it is compared against the headers using (basically) @code{strcasecmp()}, so case is ignored. @end deftypefun @deftypefun {const char *} MHD_lookup_connection_value_n (struct MHD_Connection *connection, enum MHD_ValueKind kind, const char *key, size_t key_size, const char **value_ptr, size_t *value_size_ptr) Get a particular header value. If multiple values match the @var{kind}, return one of them (the ``first'', whatever that means). @var{key} must reference an ASCII-coded string representing the header to look for: it is compared against the headers using (basically) @code{strncasecmp()}, so case is ignored. The @var{value_ptr} is set to the address of the value found, and @var{value_size_ptr} is set to the number of bytes in the value. @end deftypefun @c ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ @c ------------------------------------------------------------ @node microhttpd-responses @chapter Building responses to requests @noindent Response objects handling by MHD is asynchronous with respect to the application execution flow. Instances of the @code{MHD_Response} structure are not associated to a daemon and neither to a client connection: they are managed with reference counting. In the simplest case: we allocate a new @code{MHD_Response} structure for each response, we use it once and finally we destroy it. MHD allows more efficient resources usages. Example: we allocate a new @code{MHD_Response} structure for each response @strong{kind}, we use it every time we have to give that response and we finally destroy it only when the daemon shuts down. @menu * microhttpd-response enqueue:: Enqueuing a response. * microhttpd-response create:: Creating a response object. * microhttpd-response headers:: Adding headers to a response. * microhttpd-response options:: Setting response options. * microhttpd-response inspect:: Inspecting a response object. * microhttpd-response upgrade:: Creating a response for protocol upgrades. @end menu @c ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ @c ------------------------------------------------------------ @node microhttpd-response enqueue @section Enqueuing a response @deftypefun enum MHD_Result MHD_queue_response (struct MHD_Connection *connection, unsigned int status_code, struct MHD_Response *response) Queue a response to be transmitted to the client as soon as possible but only after MHD_AccessHandlerCallback returns.

Depending on your platform, MHD is likely to have been compiled with support for 64-bit files. When you compile your own application, you must make sure that @code{off_t} is also a 64-bit value. If not, your compiler may pass a 32-bit value as @code{off_t}, which will result in 32-bits of garbage. If you use the autotools, use the @code{AC_SYS_LARGEFILE} autoconf macro and make sure to include the generated @file{config.h} file before @file{microhttpd.h} to avoid problems. If you do not have a build system and only want to run on a GNU/Linux system, you could also use @verbatim #define _FILE_OFFSET_BITS 64 #include #include #include #include @end verbatim to ensure 64-bit @code{off_t}.

Here, a client sends a request with a ``Connection: Upgrade'' header. The server responds with a ``101 Switching Protocols'' response header, after which the two parties begin to speak a different (non-HTTP) protocol over the TCP connection. This mechanism is used for upgrading HTTP 1.1 connections to HTTP2 or HTTPS, as well as for implementing WebSockets. Which protocol upgrade is performed is negotiated between server and client in additional headers, in particular the ``Upgrade'' header. MHD supports switching protocols using this mechanism only if the @code{MHD_ALLOW_SUSPEND_RESUME} flag has been set when starting the daemon. If this flag has been set, applications can upgrade a connection by queueing a response (using the @code{MHD_HTTP_SWITCHING_PROTOCOLS} status code) which must have been created with the following function: @deftypefun enum MHD_Result MHD_create_response_for_upgrade (MHD_UpgradeHandler upgrade_handler, void *upgrade_handler_cls) Create a response suitable for switching protocols. Returns @code{MHD_YES} on success. @code{upgrade_handler} must not be @code{NULL}. When creating this type of response, the ``Connection: Upgrade'' header will be set automatically for you. MHD requires that you additionally set an ``Upgrade:'' header. The ``Upgrade'' header must simply exist, the specific value is completely up to the application. @end deftypefun The @code{upgrade_handler} argument to the above has the following type: @deftypefn {Function Pointer} void {*MHD_UpgradeHandler} (void *cls, struct MHD_Connection *connection, const char *extra_in, size_t extra_in_size, MHD_socket sock, struct MHD_UpgradeResponseHandle *urh) This function will be called once MHD has transmitted the header of the response to the connection that is being upgraded. At this point, the application is expected to take over the socket @code{sock} and speak the non-HTTP protocol to which the connection was upgraded. MHD will no longer use the socket; this includes handling timeouts. The application must call @code{MHD_upgrade_action} with an upgrade action of @code{MHD_UPGRADE_ACTION_CLOSE} when it is done processing the connection to close the socket. The application must not call @code{MHD_stop_daemon} on the respective daemon as long as it is still handling the connection. The arguments given to the @code{upgrade_handler} have the following meaning: @table @var @item cls matches the @code{upgrade_handler_cls} that was given to @code{MHD_create_response_for_upgrade} @item connection identifies the connection that is being upgraded; @item req_cls last value left in `*req_cls` in the `MHD_AccessHandlerCallback` @item extra_in buffer of bytes MHD read ``by accident'' from the socket already. This can happen if the client eagerly transmits more than just the HTTP request. The application should treat these as if it had read them from the socket. @item extra_in_size number of bytes in @code{extra_in} @item sock the socket which the application can now use directly for some bi-directional communication with the client. The application can henceforth use @code{recv()} and @code{send()} or @code{read()} and @code{write()} system calls on the socket. However, @code{ioctl()} and @code{setsockopt()} functions will not work as expected when using HTTPS. Such operations may be supported in the future via @code{MHD_upgrade_action}. Most importantly, the application must never call @code{close()} on this socket. Closing the socket must be done using @code{MHD_upgrade_action}. However, while close is forbidden, the application may call @code{shutdown()} on the socket. @item urh argument for calls to @code{MHD_upgrade_action}. Applications must eventually use this function to perform the @code{close()} action on the socket. @end table @end deftypefn @deftypefun enum MHD_Result MHD_upgrade_action (struct MHD_UpgradeResponseHandle *urh, enum MHD_UpgradeAction action, ...)

If @code{MHD_USE_THREAD_PER_CONNECTION} is used, applications can simply deal with this by performing their logic within the thread and thus effectively blocking connection processing by MHD. In all other modes, blocking logic must not be placed within the callbacks invoked by MHD as this would also block processing of other requests, as a single thread may be responsible for tens of thousands of connections. Instead, applications using thread modes other than @code{MHD_USE_THREAD_PER_CONNECTION} should use the following functions to perform flow control. @deftypefun enum MHD_Result MHD_suspend_connection (struct MHD_Connection *connection) Suspend handling of network data for a given connection. This can be used to dequeue a connection from MHD's event loop (external select, internal select or thread pool; not applicable to thread-per-connection!) for a while. If you use this API in conjunction with a internal select or a thread pool, you must set the option @code{MHD_ALLOW_SUSPEND_RESUME} to ensure that a resumed connection is immediately processed by MHD. Suspended connections continue to count against the total number of connections allowed (per daemon, as well as per IP, if such limits are set). Suspended connections will NOT time out; timeouts will restart when the connection handling is resumed. While a connection is suspended, MHD will not detect disconnects by the client. The only safe time to suspend a connection is from the @code{MHD_AccessHandlerCallback} or from the respective @code{MHD_ContentReaderCallback} (but in this case the response object must not be shared among multiple connections). When suspending from the @code{MHD_AccessHandlerCallback} you MUST afterwards return @code{MHD_YES} from the access handler callback (as MHD_NO would imply to both close and suspend the connection, which is not allowed). Finally, it is an API violation to call @code{MHD_stop_daemon} while having suspended connections (this will at least create memory and socket leaks or lead to undefined behavior). You must explicitly resume all connections before stopping the daemon. @table @var @item connection the connection to suspend @end table @end deftypefun @deftypefun enum MHD_Result MHD_resume_connection (struct MHD_Connection *connection) Resume handling of network data for suspended connection. It is safe to resume a suspended connection at any time. Calling this function on a connection that was not previously suspended will result in undefined behavior. If you are using this function in ``external'' select mode, you must make sure to run @code{MHD_run} afterwards (before again calling @code{MHD_get_fdset}), as otherwise the change may not be reflected in the set returned by @code{MHD_get_fdset} and you may end up with a connection that is stuck until the next network activity. You can check whether a connection is currently suspended using @code{MHD_get_connection_info} by querying for @code{MHD_CONNECTION_INFO_CONNECTION_SUSPENDED}. @table @var @item connection the connection to resume @end table @end deftypefun @c ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ @c ------------------------------------------------------------ @node microhttpd-dauth @chapter Utilizing Authentication @noindent MHD support three types of client authentication. Basic authentication uses a simple authentication method based on BASE64 algorithm. Username and password are exchanged in clear between the client and the server, so this method must only be used for non-sensitive content or when the session is protected with https. When using basic authentication MHD will have access to the clear password, possibly allowing to create a chained authentication toward an external authentication server. Digest authentication uses a one-way authentication method based on MD5 hash algorithm. Only the hash will transit over the network, hence protecting the user password. The nonce will prevent replay attacks. This method is appropriate for general use, especially when https is not used to encrypt the session. Client certificate authentication uses a X.509 certificate from the client. This is the strongest authentication mechanism but it requires the use of HTTPS. Client certificate authentication can be used simultaneously with Basic or Digest Authentication in order to provide a two levels authentication (like for instance separate machine and user authentication). A code example for using client certificates is presented in the MHD tutorial. @menu * microhttpd-dauth basic:: Using Basic Authentication. * microhttpd-dauth digest:: Using Digest Authentication. @end menu @c ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ @c ------------------------------------------------------------ @node microhttpd-dauth basic @section Using Basic Authentication @deftypefun {void} MHD_free (void *ptr) Free the memory given at @code{ptr}.

The fact that the pointer was initially @code{NULL} can be used to detect that this is a new request. One method to detect that a new request was started is to set @code{*req_cls} to an unused integer: @example int access_handler (void *cls, struct MHD_Connection * connection, const char *url, const char *method, const char *version, const char *upload_data, size_t *upload_data_size, void **req_cls) @{ static int old_connection_marker; int new_connection = (NULL == *req_cls); if (new_connection) @{ /* new connection with POST */ *req_cls = &old_connection_marker; @} ... @} @end example @noindent In contrast to the previous example, for @code{POST} requests in particular, it is more common to use the value of @code{*req_cls} to keep track of actual state used during processing, such as the post processor (or a struct containing a post processor): @example int access_handler (void *cls, struct MHD_Connection * connection, const char *url, const char *method, const char *version, const char *upload_data, size_t *upload_data_size, void **req_cls) @{ struct MHD_PostProcessor * pp = *req_cls; if (pp == NULL) @{ pp = MHD_create_post_processor(connection, ...); *req_cls = pp; return MHD_YES; @} if (*upload_data_size) @{ MHD_post_process(pp, upload_data, *upload_data_size); *upload_data_size = 0; return MHD_YES; @} else @{ MHD_destroy_post_processor(pp); return MHD_queue_response(...); @} @} @end example Note that the callback from @code{MHD_OPTION_NOTIFY_COMPLETED} should be used to destroy the post processor.

This can be useful if no port was specified and a client needs to learn what port is actually being used by MHD. No extra arguments should be passed. @item MHD_DAEMON_INFO_EPOLL_FD @cindex epoll Request the file-descriptor number that MHD is using for epoll. If the build is not supporting epoll, NULL is returned; if we are using a thread pool or this daemon was not started with @code{MHD_USE_EPOLL}, (a pointer to) -1 is returned. If we are using @code{MHD_USE_INTERNAL_POLLING_THREAD} or are in 'external' select mode, the internal epoll FD is returned. This function must be used in external select mode with epoll to obtain the FD to call epoll on.

No extra arguments should be passed and a pointer to a @code{union MHD_DaemonInfo} value is returned, with the @code{num_connections} member of type @code{unsigned int} set to the number of active connections. Note that in multi-threaded or internal-select mode, the real number of current connections may already be different when @code{MHD_get_daemon_info} returns.

Takes no extra arguments. @item MHD_CONNECTION_INFO_CONNECTION_FD Returns the file descriptor (usually a TCP socket) associated with this connection (in the ``connect-fd'' member of the returned struct). Note that manipulating the descriptor directly can have problematic consequences (as in, break HTTP). Applications might use this access to manipulate TCP options, for example to set the ``TCP-NODELAY'' option for COMET-like applications. Note that MHD will set TCP-CORK after sending the HTTP header and clear it after finishing the footers automatically (if the platform supports it). As the connection callbacks are invoked in between, those might be used to set different values for TCP-CORK and TCP-NODELAY in the meantime. Takes no extra arguments. @item MHD_CONNECTION_INFO_CONNECTION_SUSPENDED Returns pointer to an integer that is @code{MHD_YES} if the connection is currently suspended (and thus can be safely resumed) and @code{MHD_NO} otherwise.

Note that this is NOT the same as the @code{req_cls} argument of the @code{MHD_AccessHandlerCallback}. The @code{req_cls} is fresh for each HTTP request, while the @code{socket_context} is fresh for each socket. Takes no extra arguments. @item MHD_CONNECTION_INFO_CONNECTION_TIMEOUT Returns pointer to an @code{unsigned int} that is the current timeout used for the connection (in seconds, 0 for no timeout). Note that while suspended connections will not timeout, the timeout value returned for suspended connections will be the timeout that the connection will use after it is resumed, and thus might not be zero. Takes no extra arguments. @item MHD_CONNECTION_INFO_REQUEST_HEADER_SIZE @cindex performance Returns pointer to an @code{size_t} that represents the size of the HTTP header received from the client. Only valid after the first callback to the access handler. Takes no extra arguments. @item MHD_CONNECTION_INFO_HTTP_STATUS Returns the HTTP status code of the response that was queued.
