If you want specific instructions for some distributions, check the [wiki](https://github.com/s3fs-fuse/s3fs-fuse/wiki/Installation-Notes). Keep in mind using the pre-built packages when available. 1. Ensure your system satisfies build and runtime dependencies for: * fuse >= 2.8.4 * automake * gcc-c++ * make * libcurl * libxml2 * openssl * mime.types (the package providing depends on the OS) * s3fs tries to detect `/etc/mime.types` as default regardless of the OS * Else s3fs tries to detect `/etc/apache2/mime.types` if OS is macOS * s3fs exits with an error if these files are not exist * Alternatively, you can set mime.types file path with `mime` option without detecting these default files * pkg-config (or your OS equivalent) 2. Then compile from master via the following commands: ``` git clone https://github.com/s3fs-fuse/s3fs-fuse.git cd s3fs-fuse ./autogen.sh ./configure make sudo make install ``` s3fs-fuse-1.90/COPYING000066400000000000000000000431031410366243700143230ustar00rootroot00000000000000 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 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. 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. GNU GENERAL PUBLIC LICENSE 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 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. Copyright (C) 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. , 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. s3fs-fuse-1.90/ChangeLog000066400000000000000000000664651410366243700150620ustar00rootroot00000000000000ChangeLog for S3FS ------------------ Version 1.90 -- 07 Aug, 2021 (major changes only) #1599 -

This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell commands `./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 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. 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 bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /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. s3fs-fuse-1.90/Makefile.am000066400000000000000000000034341410366243700153270ustar00rootroot00000000000000###################################################################### # s3fs - FUSE-based file system backed by Amazon S3 # # Copyright 2007-2008 Randy Rizun # # 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.

[![s3fs-fuse CI](https://github.com/s3fs-fuse/s3fs-fuse/workflows/s3fs-fuse%20CI/badge.svg)](https://github.com/s3fs-fuse/s3fs-fuse/actions) [![Twitter Follow](https://img.shields.io/twitter/follow/s3fsfuse.svg?style=social&label=Follow)](https://twitter.com/s3fsfuse) ## Features * large subset of POSIX including reading/writing files, directories, symlinks, mode, uid/gid, and extended attributes * compatible with Amazon S3, and other [S3-based object stores](https://github.com/s3fs-fuse/s3fs-fuse/wiki/Non-Amazon-S3) * allows random writes and appends * large files via multi-part upload * renames via server-side copy * optional server-side encryption * data integrity via MD5 hashes * in-memory metadata caching * local disk data caching * user-specified regions, including Amazon GovCloud * authenticate via v2 or v4 signatures ## Installation Many systems provide pre-built packages: * Amazon Linux via EPEL: ``` sudo amazon-linux-extras install epel sudo yum install s3fs-fuse ``` * Arch Linux: ``` sudo pacman -S s3fs-fuse ``` * Debian 9 and Ubuntu 16.04 or newer: ``` sudo apt install s3fs ``` * Fedora 27 or newer: ``` sudo dnf install s3fs-fuse ``` * Gentoo: ``` sudo emerge net-fs/s3fs ``` * RHEL and CentOS 7 or newer via EPEL: ``` sudo yum install epel-release sudo yum install s3fs-fuse ``` * SUSE 12 and openSUSE 42.1 or newer: ``` sudo zypper install s3fs ``` * macOS via [Homebrew](https://brew.sh/): ``` brew install --cask osxfuse brew install s3fs ``` Note: Homebrew has deprecated osxfuse and s3fs may not install any more, see [#1618](https://github.com/s3fs-fuse/s3fs-fuse/issues/1618). Otherwise consult the [compilation instructions](COMPILATION.md). ## Examples s3fs supports the standard [AWS credentials file](https://docs.aws.amazon.com/cli/latest/userguide/cli-config-files.html) stored in `${HOME}/.aws/credentials`. Alternatively, s3fs supports a custom passwd file. The default location for the s3fs password file can be created: * using a `.passwd-s3fs` file in the users home directory (i.e. `${HOME}/.passwd-s3fs`) * using the system-wide `/etc/passwd-s3fs` file Enter your credentials in a file `${HOME}/.passwd-s3fs` and set owner-only permissions: ``` echo ACCESS_KEY_ID:SECRET_ACCESS_KEY > ${HOME}/.passwd-s3fs chmod 600 ${HOME}/.passwd-s3fs ``` Run s3fs with an existing bucket `mybucket` and directory `/path/to/mountpoint`: ``` s3fs mybucket /path/to/mountpoint -o passwd_file=${HOME}/.passwd-s3fs ``` If you encounter any errors, enable debug output: ``` s3fs mybucket /path/to/mountpoint -o passwd_file=${HOME}/.passwd-s3fs -o dbglevel=info -f -o curldbg ``` You can also mount on boot by entering the following line to `/etc/fstab`: ``` mybucket /path/to/mountpoint fuse.s3fs _netdev,allow_other 0 0 ``` If you use s3fs with a non-Amazon S3 implementation, specify the URL and path-style requests: ``` s3fs mybucket /path/to/mountpoint -o passwd_file=${HOME}/.passwd-s3fs -o url=https://url.to.s3/ -o use_path_request_style ``` or(fstab) ``` mybucket /path/to/mountpoint fuse.s3fs _netdev,allow_other,use_path_request_style,url=https://url.to.s3/ 0 0 ``` Note: You may also want to create the global credential file first ``` echo ACCESS_KEY_ID:SECRET_ACCESS_KEY > /etc/passwd-s3fs chmod 600 /etc/passwd-s3fs ``` Note2: You may also need to make sure `netfs` service is start on boot ## Limitations Generally S3 cannot offer the same performance or semantics as a local file system. More specifically: * random writes or appends to files require rewriting the entire object, optimized with multi-part upload copy * metadata operations such as listing directories have poor performance due to network latency * non-AWS providers may have [eventual consistency](https://en.wikipedia.org/wiki/Eventual_consistency) so reads can temporarily yield stale data (AWS offers read-after-write consistency [since Dec 2020](https://aws.amazon.com/about-aws/whats-new/2020/12/amazon-s3-now-delivers-strong-read-after-write-consistency-automatically-for-all-applications/)) * no atomic renames of files or directories * no coordination between multiple clients mounting the same bucket * no hard links * inotify detects only local modifications, not external ones by other clients or tools ## References * [goofys](https://github.com/kahing/goofys) - similar to s3fs but has better performance and less POSIX compatibility * [s3backer](https://github.com/archiecobbs/s3backer) - mount an S3 bucket as a single file * [S3Proxy](https://github.com/gaul/s3proxy) - combine with s3fs to mount Backblaze B2, EMC Atmos, Microsoft Azure, and OpenStack Swift buckets * [s3ql](https://github.com/s3ql/s3ql/) - similar to s3fs but uses its own object format * [YAS3FS](https://github.com/danilop/yas3fs) - similar to s3fs but uses SNS to allow multiple clients to mount a bucket ## Frequently Asked Questions * [FAQ wiki page](https://github.com/s3fs-fuse/s3fs-fuse/wiki/FAQ) * [s3fs on Stack Overflow](https://stackoverflow.com/questions/tagged/s3fs) * [s3fs on Server Fault](https://serverfault.com/questions/tagged/s3fs) ## License Copyright (C) 2010 Randy Rizun Licensed under the GNU GPL version 2 s3fs-fuse-1.90/autogen.sh000077500000000000000000000025211410366243700152700ustar00rootroot00000000000000#! /bin/sh # This file is part of S3FS. # # Copyright 2009, 2010 Free Software Foundation, Inc. # # S3FS 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 of the License, or (at # your option) any later version. # # S3FS 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.

It stores files natively and transparently in S3 (i.e., you can use other programs to access the same files). .SH AUTHENTICATION s3fs supports the standard AWS credentials file (https://docs.aws.amazon.com/cli/latest/userguide/cli-config-files.html) stored in `${HOME}/.aws/credentials`. Alternatively, s3fs supports a custom passwd file. Only AWS credentials file format can be used when AWS session token is required. The s3fs password file has this format (use this format if you have only one set of credentials): .RS 4 \fBaccessKeyId\fP:\fBsecretAccessKey\fP .RE If you have more than one set of credentials, this syntax is also recognized: .RS 4 \fBbucketName\fP:\fBaccessKeyId\fP:\fBsecretAccessKey\fP .RE .PP Password files can be stored in two locations: .RS 4 \fB/etc/passwd-s3fs\fP [0640] \fB$HOME/.passwd-s3fs\fP [0600] .RE .PP s3fs also recognizes the \fBAWS_ACCESS_KEY_ID\fP and \fBAWS_SECRET_ACCESS_KEY\fP environment variables. .SH OPTIONS .SS "general options" .TP \fB\-h\fR \fB\-\-help\fR print help .TP \fB\ \fR \fB\-\-version\fR print version .TP \fB\-f\fR FUSE foreground option - do not run as daemon. .TP \fB\-s\fR FUSE single-threaded option (disables multi-threaded operation) .SS "mount options" .TP All s3fs options must given in the form where "opt" is: = .TP \fB\-o\fR bucket if it is not specified bucket name (and path) in command line, must specify this option after \-o option for bucket name. .TP \fB\-o\fR default_acl (default="private") the default canned acl to apply to all written s3 objects, e.g., "private", "public-read". see https://docs.aws.amazon.com/AmazonS3/latest/dev/acl-overview.html#canned-acl for the full list of canned acls. .TP \fB\-o\fR retries (default="5") number of times to retry a failed S3 transaction. .TP \fB\-o\fR tmpdir (default="/tmp") local folder for temporary files. .TP \fB\-o\fR use_cache (default="" which means disabled) local folder to use for local file cache. .TP \fB\-o\fR check_cache_dir_exist (default is disable) If use_cache is set, check if the cache directory exists. If this option is not specified, it will be created at runtime when the cache directory does not exist. .TP \fB\-o\fR del_cache - delete local file cache delete local file cache when s3fs starts and exits. .TP \fB\-o\fR storage_class (default="standard") store object with specified storage class. Possible values: standard, standard_ia, onezone_ia, reduced_redundancy, intelligent_tiering, glacier, and deep_archive. .TP \fB\-o\fR use_rrs (default is disable) use Amazon's Reduced Redundancy Storage. this option can not be specified with use_sse. (can specify use_rrs=1 for old version) this option has been replaced by new storage_class option. .TP \fB\-o\fR use_sse (default is disable) Specify three type Amazon's Server-Site Encryption: SSE-S3, SSE-C or SSE-KMS. SSE-S3 uses Amazon S3-managed encryption keys, SSE-C uses customer-provided encryption keys, and SSE-KMS uses the master key which you manage in AWS KMS. You can specify "use_sse" or "use_sse=1" enables SSE-S3 type (use_sse=1 is old type parameter). Case of setting SSE-C, you can specify "use_sse=custom", "use_sse=custom:" or "use_sse=" (only specified is old type parameter). You can use "c" for short "custom". The custom key file must be 600 permission. The file can have some lines, each line is one SSE-C key. The first line in file is used as Customer-Provided Encryption Keys for uploading and changing headers etc. If there are some keys after first line, those are used downloading object which are encrypted by not first key. So that, you can keep all SSE-C keys in file, that is SSE-C key history. If you specify "custom" ("c") without file path, you need to set custom key by load_sse_c option or AWSSSECKEYS environment. (AWSSSECKEYS environment has some SSE-C keys with ":" separator.) This option is used to decide the SSE type. So that if you do not want to encrypt a object at uploading, but you need to decrypt encrypted object at downloading, you can use load_sse_c option instead of this option. For setting SSE-KMS, specify "use_sse=kmsid" or "use_sse=kmsid:". You can use "k" for short "kmsid". If you san specify SSE-KMS type with your in AWS KMS, you can set it after "kmsid:" (or "k:"). If you specify only "kmsid" ("k"), you need to set AWSSSEKMSID environment which value is . You must be careful about that you can not use the KMS id which is not same EC2 region. .TP \fB\-o\fR load_sse_c - specify SSE-C keys Specify the custom-provided encryption keys file path for decrypting at downloading. If you use the custom-provided encryption key at uploading, you specify with "use_sse=custom". The file has many lines, one line means one custom key. So that you can keep all SSE-C keys in file, that is SSE-C key history. AWSSSECKEYS environment is as same as this file contents. .TP \fB\-o\fR passwd_file (default="") specify the path to the password file, which which takes precedence over the password in $HOME/.passwd-s3fs and /etc/passwd-s3fs .TP \fB\-o\fR ahbe_conf (default="" which means disabled) This option specifies the configuration file path which file is the additional HTTP header by file (object) extension. The configuration file format is below: ----------- line = [file suffix or regex] HTTP-header [HTTP-values] file suffix = file (object) suffix, if this field is empty, it means "reg:(.*)".(=all object). regex = regular expression to match the file (object) path. this type starts with "reg:" prefix. HTTP-header = additional HTTP header name HTTP-values = additional HTTP header value ----------- Sample: ----------- .gz Content-Encoding gzip .Z Content-Encoding compress reg:^/MYDIR/(.*)[.]t2$ Content-Encoding text2 ----------- A sample configuration file is uploaded in "test" directory. If you specify this option for set "Content-Encoding" HTTP header, please take care for RFC 2616. .TP \fB\-o\fR profile (default="default") Choose a profile from ${HOME}/.aws/credentials to authenticate against S3. Note that this format matches the AWS CLI format and differs from the s3fs passwd format. .TP \fB\-o\fR public_bucket (default="" which means disabled) anonymously mount a public bucket when set to 1, ignores the $HOME/.passwd-s3fs and /etc/passwd-s3fs files. S3 does not allow copy object api for anonymous users, then s3fs sets nocopyapi option automatically when public_bucket=1 option is specified. .TP \fB\-o\fR connect_timeout (default="300" seconds) time to wait for connection before giving up. .TP \fB\-o\fR readwrite_timeout (default="120" seconds) time to wait between read/write activity before giving up. .TP \fB\-o\fR list_object_max_keys (default="1000") specify the maximum number of keys returned by S3 list object API. The default is 1000. you can set this value to 1000 or more. .TP \fB\-o\fR max_stat_cache_size (default="100,000" entries (about 40MB)) maximum number of entries in the stat cache and symbolic link cache. .TP \fB\-o\fR stat_cache_expire (default is 900) specify expire time (seconds) for entries in the stat cache and symbolic link cache. This expire time indicates the time since cached. .TP \fB\-o\fR stat_cache_interval_expire (default is 900) specify expire time (seconds) for entries in the stat cache and symbolic link cache. This expire time is based on the time from the last access time of those cache. This option is exclusive with stat_cache_expire, and is left for compatibility with older versions. .TP \fB\-o\fR enable_noobj_cache (default is disable) enable cache entries for the object which does not exist. s3fs always has to check whether file (or sub directory) exists under object (path) when s3fs does some command, since s3fs has recognized a directory which does not exist and has files or sub directories under itself. It increases ListBucket request and makes performance bad. You can specify this option for performance, s3fs memorizes in stat cache that the object (file or directory) does not exist. .TP \fB\-o\fR no_check_certificate (by default this option is disabled) server certificate won't be checked against the available certificate authorities. .TP \fB\-o\fR ssl_verify_hostname (default="2") When 0, do not verify the SSL certificate against the hostname. .TP \fB\-o\fR nodnscache - disable DNS cache. s3fs is always using DNS cache, this option make DNS cache disable. .TP \fB\-o\fR nosscache - disable SSL session cache. s3fs is always using SSL session cache, this option make SSL session cache disable. .TP \fB\-o\fR multireq_max (default="20") maximum number of parallel request for listing objects. .TP \fB\-o\fR parallel_count (default="5") number of parallel request for uploading big objects. s3fs uploads large object (over 20MB) by multipart post request, and sends parallel requests. This option limits parallel request count which s3fs requests at once. It is necessary to set this value depending on a CPU and a network band. .TP \fB\-o\fR multipart_size (default="10") part size, in MB, for each multipart request. The minimum value is 5 MB and the maximum value is 5 GB. .TP \fB\-o\fR multipart_copy_size (default="512") part size, in MB, for each multipart copy request, used for renames and mixupload. The minimum value is 5 MB and the maximum value is 5 GB. Must be at least 512 MB to copy the maximum 5 TB object size but lower values may improve performance. .TP \fB\-o\fR max_dirty_data (default="5120") Flush dirty data to S3 after a certain number of MB written. The minimum value is 50 MB. -1 value means disable. Cannot be used with nomixupload. .TP \fB\-o\fR ensure_diskfree (default 0) sets MB to ensure disk free space. This option means the threshold of free space size on disk which is used for the cache file by s3fs. s3fs makes file for downloading, uploading and caching files. If the disk free space is smaller than this value, s3fs do not use diskspace as possible in exchange for the performance. .TP \fB\-o\fR multipart_threshold (default="25") threshold, in MB, to use multipart upload instead of single-part. Must be at least 5 MB. .TP \fB\-o\fR singlepart_copy_limit (default="512") maximum size, in MB, of a single-part copy before trying multipart copy. .TP \fB\-o\fR host (default="https://s3.amazonaws.com") Set a non-Amazon host, e.g., https://example.com. .TP \fB\-o\fR servicepath (default="/") Set a service path when the non-Amazon host requires a prefix. .TP \fB\-o\fR url (default="https://s3.amazonaws.com") sets the url to use to access Amazon S3. If you want to use HTTP, then you can set "url=http://s3.amazonaws.com". If you do not use https, please specify the URL with the url option. .TP \fB\-o\fR endpoint (default="us-east-1") sets the endpoint to use on signature version 4. If this option is not specified, s3fs uses "us-east-1" region as the default. If the s3fs could not connect to the region specified by this option, s3fs could not run. But if you do not specify this option, and if you can not connect with the default region, s3fs will retry to automatically connect to the other region. So s3fs can know the correct region name, because s3fs can find it in an error from the S3 server. .TP \fB\-o\fR sigv2 (default is signature version 4 falling back to version 2) sets signing AWS requests by using only signature version 2. .TP \fB\-o\fR sigv4 (default is signature version 4 falling back to version 2) sets signing AWS requests by using only signature version 4. .TP \fB\-o\fR mp_umask (default is "0000") sets umask for the mount point directory. If allow_other option is not set, s3fs allows access to the mount point only to the owner. In the opposite case s3fs allows access to all users as the default. But if you set the allow_other with this option, you can control the permissions of the mount point by this option like umask. .TP \fB\-o\fR umask (default is "0000") sets umask for files under the mountpoint. This can allow users other than the mounting user to read and write to files that they did not create. .TP \fB\-o\fR nomultipart - disable multipart uploads .TP \fB\-o\fR enable_content_md5 (default is disable) Allow S3 server to check data integrity of uploads via the Content-MD5 header. This can add CPU overhead to transfers. .TP \fB\-o\fR ecs (default is disable) This option instructs s3fs to query the ECS container credential metadata address instead of the instance metadata address. .TP \fB\-o\fR iam_role (default is no IAM role) This option requires the IAM role name or "auto". If you specify "auto", s3fs will automatically use the IAM role names that are set to an instance. If you specify this option without any argument, it is the same as that you have specified the "auto". .TP \fB\-o\fR imdsv1only (default is to use IMDSv2 with fallback to v1) AWS instance metadata service, used with IAM role authentication, supports the use of an API token. If you're using an IAM role in an environment that does not support IMDSv2, setting this flag will skip retrieval and usage of the API token when retrieving IAM credentials. .TP \fB\-o\fR ibm_iam_auth (default is not using IBM IAM authentication) This option instructs s3fs to use IBM IAM authentication. In this mode, the AWSAccessKey and AWSSecretKey will be used as IBM's Service-Instance-ID and APIKey, respectively. .TP \fB\-o\fR ibm_iam_endpoint (default is https://iam.cloud.ibm.com) Sets the URL to use for IBM IAM authentication. .TP \fB\-o\fR use_xattr (default is not handling the extended attribute) Enable to handle the extended attribute (xattrs). If you set this option, you can use the extended attribute. For example, encfs and ecryptfs need to support the extended attribute. Notice: if s3fs handles the extended attribute, s3fs can not work to copy command with preserve=mode. .TP \fB\-o\fR noxmlns - disable registering xml name space. disable registering xml name space for response of ListBucketResult and ListVersionsResult etc. Default name space is looked up from "http://s3.amazonaws.com/doc/2006-03-01". This option should not be specified now, because s3fs looks up xmlns automatically after v1.66. .TP \fB\-o\fR nomixupload - disable copy in multipart uploads. Disable to use PUT (copy api) when multipart uploading large size objects. By default, when doing multipart upload, the range of unchanged data will use PUT (copy api) whenever possible. When nocopyapi or norenameapi is specified, use of PUT (copy api) is invalidated even if this option is not specified. .TP \fB\-o\fR nocopyapi - for other incomplete compatibility object storage. For a distributed object storage which is compatibility S3 API without PUT (copy api). If you set this option, s3fs do not use PUT with "x-amz-copy-source" (copy api). Because traffic is increased 2-3 times by this option, we do not recommend this. .TP \fB\-o\fR norenameapi - for other incomplete compatibility object storage. For a distributed object storage which is compatibility S3 API without PUT (copy api). This option is a subset of nocopyapi option. The nocopyapi option does not use copy-api for all command (ex. chmod, chown, touch, mv, etc), but this option does not use copy-api for only rename command (ex. mv). If this option is specified with nocopyapi, then s3fs ignores it. .TP \fB\-o\fR use_path_request_style (use legacy API calling style) Enable compatibility with S3-like APIs which do not support the virtual-host request style, by using the older path request style. .TP \fB\-o\fR listobjectsv2 (use ListObjectsV2) Issue ListObjectsV2 instead of ListObjects, useful on object stores without ListObjects support. .TP \fB\-o\fR noua (suppress User-Agent header) Usually s3fs outputs of the User-Agent in "s3fs/ (commit hash ; )" format. If this option is specified, s3fs suppresses the output of the User-Agent. .TP \fB\-o\fR cipher_suites Customize the list of TLS cipher suites. Expects a colon separated list of cipher suite names. A list of available cipher suites, depending on your TLS engine, can be found on the CURL library documentation: https://curl.haxx.se/docs/ssl-ciphers.html .TP \fB\-o\fR instance_name The instance name of the current s3fs mountpoint. This name will be added to logging messages and user agent headers sent by s3fs. .TP \fB\-o\fR complement_stat (complement lack of file/directory mode) s3fs complements lack of information about file/directory mode if a file or a directory object does not have x-amz-meta-mode header. As default, s3fs does not complements stat information for a object, then the object will not be able to be allowed to list/modify. .TP \fB\-o\fR notsup_compat_dir (not support compatibility directory types) As a default, s3fs supports objects of the directory type as much as possible and recognizes them as directories. Objects that can be recognized as directory objects are "dir/", "dir", "dir_$folder$", and there is a file object that does not have a directory object but contains that directory path. s3fs needs redundant communication to support all these directory types. The object as the directory created by s3fs is "dir/". By restricting s3fs to recognize only "dir/" as a directory, communication traffic can be reduced. This option is used to give this restriction to s3fs. However, if there is a directory object other than "dir/" in the bucket, specifying this option is not recommended. s3fs may not be able to recognize the object correctly if an object created by s3fs exists in the bucket. Please use this option when the directory in the bucket is only "dir/" object. .TP \fB\-o\fR use_wtf8 - support arbitrary file system encoding. S3 requires all object names to be valid UTF-8. But some clients, notably Windows NFS clients, use their own encoding. This option re-encodes invalid UTF-8 object names into valid UTF-8 by mapping offending codes into a 'private' codepage of the Unicode set. Useful on clients not using UTF-8 as their file system encoding. .TP \fB\-o\fR use_session_token - indicate that session token should be provided. If credentials are provided by environment variables this switch forces presence check of AWS_SESSION_TOKEN variable. Otherwise an error is returned. .TP \fB\-o\fR requester_pays (default is disable) This option instructs s3fs to enable requests involving Requester Pays buckets (It includes the 'x-amz-request-payer=requester' entry in the request header). .TP \fB\-o\fR mime (default is "/etc/mime.types") Specify the path of the mime.types file. If this option is not specified, the existence of "/etc/mime.types" is checked, and that file is loaded as mime information. If this file does not exist on macOS, then "/etc/apache2/mime.types" is checked as well. .TP \fB\-o\fR logfile - specify the log output file. s3fs outputs the log file to syslog. Alternatively, if s3fs is started with the "-f" option specified, the log will be output to the stdout/stderr. You can use this option to specify the log file that s3fs outputs. If you specify a log file with this option, it will reopen the log file when s3fs receives a SIGHUP signal. You can use the SIGHUP signal for log rotation. .TP \fB\-o\fR dbglevel (default="crit") Set the debug message level. set value as crit (critical), err (error), warn (warning), info (information) to debug level. default debug level is critical. If s3fs run with "-d" option, the debug level is set information. When s3fs catch the signal SIGUSR2, the debug level is bump up. .TP \fB\-o\fR curldbg - put curl debug message Put the debug message from libcurl when this option is specified. Specify "normal" or "body" for the parameter. If the parameter is omitted, it is the same as "normal". If "body" is specified, some API communication body data will be output in addition to the debug message output as "normal". .TP \fB\-o\fR no_time_stamp_msg - no time stamp in debug message The time stamp is output to the debug message by default. If this option is specified, the time stamp will not be output in the debug message. It is the same even if the environment variable "S3FS_MSGTIMESTAMP" is set to "no". .TP \fB\-o\fR set_check_cache_sigusr1 (default is stdout) If the cache is enabled, you can check the integrity of the cache file and the cache file's stats info file. This option is specified and when sending the SIGUSR1 signal to the s3fs process checks the cache status at that time. This option can take a file path as parameter to output the check result to that file. The file path parameter can be omitted. If omitted, the result will be output to stdout or syslog. .SS "utility mode options" .TP \fB\-u\fR or \fB\-\-incomplete\-mpu\-list\fR Lists multipart incomplete objects uploaded to the specified bucket. .TP \fB\-\-incomplete\-mpu\-abort\fR all or date format (default="24H") Delete the multipart incomplete object uploaded to the specified bucket. If "all" is specified for this option, all multipart incomplete objects will be deleted. If you specify no argument as an option, objects older than 24 hours (24H) will be deleted (This is the default value). You can specify an optional date format. It can be specified as year, month, day, hour, minute, second, and it is expressed as "Y", "M", "D", "h", "m", "s" respectively. For example, "1Y6M10D12h30m30s". .SH FUSE/MOUNT OPTIONS .TP Most of the generic mount options described in 'man mount' are supported (ro, rw, suid, nosuid, dev, nodev, exec, noexec, atime, noatime, sync async, dirsync). Filesystems are mounted with '\-onodev,nosuid' by default, which can only be overridden by a privileged user. .TP There are many FUSE specific mount options that can be specified. e.g. allow_other. See the FUSE README for the full set. .SH LOCAL STORAGE CONSUMPTION .TP s3fs requires local caching for operation. You can enable a local cache with "\-o use_cache" or s3fs uses temporary files to cache pending requests to s3. .TP Apart from the requirements discussed below, it is recommended to keep enough cache resp. temporary storage to allow one copy each of all files open for reading and writing at any one time. .TP .SS Local cache with \[dq]\-o use_cache\[dq] .TP s3fs automatically maintains a local cache of files. The cache folder is specified by the parameter of "\-o use_cache". It is only a local cache that can be deleted at any time. s3fs rebuilds it if necessary. .TP Whenever s3fs needs to read or write a file on S3, it first creates the file in the cache directory and operates on it. .TP The amount of local cache storage used can be indirectly controlled with "\-o ensure_diskfree". .TP .SS Without local cache .TP Since s3fs always requires some storage space for operation, it creates temporary files to store incoming write requests until the required s3 request size is reached and the segment has been uploaded. After that, this data is truncated in the temporary file to free up storage space. .TP Per file you need at least twice the part size (default 5MB or "-o multipart_size") for writing multipart requests or space for the whole file if single requests are enabled ("\-o nomultipart"). .SH NOTES .TP The maximum size of objects that s3fs can handle depends on Amazon S3. For example, up to 5 GB when using single PUT API. And up to 5 TB is supported when Multipart Upload API is used. .TP s3fs leverages /etc/mime.types to "guess" the "correct" content-type based on file name extension. This means that you can copy a website to S3 and serve it up directly from S3 with correct content-types! .SH SEE ALSO fuse(8), mount(8), fusermount(1), fstab(5) .SH BUGS Due to S3's "eventual consistency" limitations, file creation can and will occasionally fail. Even after a successful create, subsequent reads can fail for an indeterminate time, even after one or more successful reads. Create and read enough files and you will eventually encounter this failure. This is not a flaw in s3fs and it is not something a FUSE wrapper like s3fs can work around. The retries option does not address this issue. Your application must either tolerate or compensate for these failures, for example by retrying creates or reads. .SH AUTHOR s3fs has been written by Randy Rizun . s3fs-fuse-1.90/doc/s3fs.png000066400000000000000000000124021410366243700154170ustar00rootroot00000000000000PNG  IHDR\rf pHYs.#.#x?vtIME  tEXtCommentCreated with GIMPW|IDATx}tT?I&1&@d*(A,ڂ/cDkc={mHǺvk[ۜVVmWQV׵ewMנkTePK${}~ιg2Ν{rA!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!B!BPKPZ[6󾩡KRH kosmOI?>asom)۶U $uP̷^ZBa`ASCJ·v/ӏ$@QI}gge@^B $p| (_\J֪F $;~'RhMB $C;=j!)`-"'-O0wkh@AȞ믰"(aj"b'"f%%Dut#n.K#% _" ByD?aI't9$asF9"(P [οV"*lZ %f?>ӥU('bٴZ6M7Z=l9kWEA-&A޿ w՘Kh4% UˏtQp%^6-n䟄]˦6ly_j+HZ6MPRW{R{lZSڀii4 Z] ,߶"*Z6-.'ہ 4ꄕ6&Gjztp#0>p:fOX#6"lZX/# _=P/$"eӂ.3%"ށ` @&bGf@Ὲ$%Mz@4W/JL,q =<ȩ@p@@TtqPFjR@ vBxF(J e%B( (@ DԢ!e\@D‘~&~$yH\ QM0[U)$D`+ @J" |$^r (@( tK =&|i1_+ , \{L\gY*t )65tIrw$0X t?GZŖ_cNpz@6;pp?;6}¸@cWK^99:ÁN :a0jjv2렶z 0a2TU;k/S?C{lK}#M m~;28~r3@_yv ;`cۓWCzaH̅1̦zO+|͛?azԐd+&L~5ذy1_5x\z\\1!vRAJV?bhY3 n:̽< ~(<|>W*98Nxa@e{;I?4^7njye~B} 7 ӭ߯oI[4"@vW^~>y};9_ /!V]"B]S@y?`<}8rݾ{ wU7iPy?{ZP@@ί  P7 3δUP^aOC]{+tl][a<>\&F6@19ϸf1ۄQi2.'޷˝q(4aJ3ijX/{g[?NY8&|e?p9_agx-9RΟSg¢s~;5_p_ w8[]G8o'wxN3cmn3ɦv oքŞh ?|vx ATo^\o1-.5y{f&^eUicp>XxxYgT6L ŋ`Xpz?cFYv,Ŀ}&OV5lxp&E@(O碓1n{ Q@O,T_n}ïDFLu[ʦË@s>p _?< w}A~Ug]s‚dp~cl:2 d[~l=Mk+kLRpzlS}z@̡' 9/ߴ߸Rس@W84Ȥ0ig 6q4Uf>8q 9rt9m{)[ƻእ0jlpY6ڞt{s_Ls_nXe*b?l [S -3ˀ4@6 MWI shYeīW S4ۂŰ&G=g@L?8ο& ߾itd[p]V+w\v/צi=Dr Vre_@x{nl| ԯ$,Kh epb>mEmVCz鼲iX Nul+` Wk1f&x Mw$l4 hq'י~n'O<$ͅa\Τt$8a`ïYpՍiyh8ߘ' B}0ǮK0BqSor^ӏ} wlzq[~ r_zlpH2nZ?̈́)/d>o~k'g`MYTT.QcM5l#*rb ݑ篽]]mZ(,~Y*k}>l(``(ƌ3۴YǏ  5}rJt4DPT;zo+[ë92c2L4U up|3ëq]{}>ìހ jy_i.}c0elM%O؟1L3vc9|Ag夨O>`{+q6~j쳖?b~:6O^ 0Aωƃ{{`NpQz$`:Jke{x槰cs߻λto~VplZH ̖MΞ|+[#P6[T,f ƹ^v\ ,L6 @ᯃK>n YѲj%h) ><P6-dq7W.99Yu"6kn1'L}BˣUžћKʦJ|s VDg/+LS**diqvm5ݍƜpulZHR9Ay 9ho64ɓN SaTLjs7${~3smؿ4D fĩ0~YIJxQ6 YWK4)HP @ӐA@ D%nBIt݄45 Iig@Qͭ D!
