The dnl default (if it is not specified or empty) is 'no-libtool'. dnl INTLSYMBOL should be 'external' for packages with no intl directory, dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. dnl If INTLSYMBOL is 'use-libtool', then a libtool library dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, dnl depending on --{enable,disable}-{shared,static} and on the presence of dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library dnl $(top_builddir)/intl/libintl.a will be created. dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext dnl implementations (in libc or libintl) without the ngettext() function dnl will be ignored. If NEEDSYMBOL is specified and is dnl 'need-formatstring-macros', then GNU gettext implementations that don't dnl support the ISO C 99 formatstring macros will be ignored. dnl INTLDIR is used to find the intl libraries. If empty, dnl the value `$(top_builddir)/intl/' is used. dnl dnl The result of the configuration is one of three cases: dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled dnl and used. dnl Catalog format: GNU --> install in $(datadir) dnl Catalog extension: .mo after installation, .gmo in source tree dnl 2) GNU gettext has been found in the system's C library. dnl Catalog format: GNU --> install in $(datadir) dnl Catalog extension: .mo after installation, .gmo in source tree dnl 3) No internationalization, always use English msgid. dnl Catalog format: none dnl Catalog extension: none dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. dnl The use of .gmo is historical (it was needed to avoid overwriting the dnl GNU format catalogs when building on a platform with an X/Open gettext), dnl but we keep it in order not to force irrelevant filename changes on the dnl maintainers. dnl AC_DEFUN([AM_GNU_GETTEXT], [ dnl Argument checking. ifelse([$1], [], , [ifelse([$1], [external], , [ifelse([$1], [no-libtool], , [ifelse([$1], [use-libtool], , [errprint([ERROR: invalid first argument to AM_GNU_GETTEXT ])])])])]) ifelse([$2], [], , [ifelse([$2], [need-ngettext], , [ifelse([$2], [need-formatstring-macros], , [errprint([ERROR: invalid second argument to AM_GNU_GETTEXT ])])])]) define([gt_included_intl], ifelse([$1], [external], ifdef([AM_GNU_GETTEXT_][INTL_SUBDIR], [yes], [no]), [yes])) define([gt_libtool_suffix_prefix], ifelse([$1], [use-libtool], [l], [])) gt_NEEDS_INIT AM_GNU_GETTEXT_NEED([$2]) AC_REQUIRE([AM_PO_SUBDIRS])dnl ifelse(gt_included_intl, yes, [ AC_REQUIRE([AM_INTL_SUBDIR])dnl ]) dnl Prerequisites of AC_LIB_LINKFLAGS_BODY.

Precompiled binaries are available for some platforms at the download page http://www.c-pluff.org/download For help on building C-Pluff based applications, see the examples in the examples directory. Prerequisites ------------- To build C-Pluff, you need to have following prerequisites installed: - a C library supporting POSIX dlopen (for example, GNU C library) or GNU Libtool libltdl library (http://www.gnu.org/software/libtool/) - Expat XML Parser library for C (http://expat.sourceforge.net/) Following components are optional and are used if they are installed: - GNU gettext libintl library for localization (http://www.gnu.org/software/gettext/gettext.html) - GNU Readline Library for enhanced command line (http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html) Building -------- To build C-Pluff, follow the usual autotools procedure: Building in the source directory: ./configure make Building in a separate build directory: cd BUILD_DIR SOURCE_DIR/configure make You can specify the installation prefix (for example, /usr or /usr/local) when running the configure script. ./configure --prefix=/usr The default installation prefix is /usr/local. More help on available configuration options is available using the --help option. ./configure --help Installation ------------ You can install the library, header files, utilities, documentation and examples by making target install: make install If installing to system directories you have to do this as root. Additionally, you can specify a directory to be used in place of the root directory during installation. This is typically used to create binary packages. make DESTDIR=/tmp/installation install Known good build platforms -------------------------- C-Pluff is known to compile cleanly on following combinations: - Native Linux build - GCC 4.1.2 - GNU C library 2.3.6 - Expat 1.95.8 - Cross compilation for Windows on Linux - MinGW Runtime 3.9 - MinGW binutils 2.16.91 - MinGW 3.4.5 - Expat 2.0.0 (or 1.95.8 or 1.95.1) - GNU Libtool libltdl 1.5.22 - GNU Gettext 0.16.1 (or 0.14.4) cpluff-0.1.3/ChangeLog.txt0000644000076400001440000000544510605437331012315 00000000000000C-Pluff (0.1.3) alpha * Fixed a bug in Windows multi-threading support. Mutex was not actually locked in cpi_lock_mutex. * Fixed a bug in libltdl support. libltdl was not being initialized. * Made cpfile example application compatible with Windows. * Added Windows packaging using cross-compilation on Debian. * Added Microsoft Visual C build environment for examples. * Small improvements to installation documentation and packaging. * Support Expat 1.95.1 and GnuWin32 version of libintl. * Tools: Delegate binding of gettext domain to the library. * Moved documentation sources out from C source directories. -- Johannes Lehtinen Fri, 6 Apr 2007 15:36:30 +0300 C-Pluff (0.1.2) alpha * Removed a flawed check of whether dynamically resolved symbols are in use when a plug-in is being stopped. * Fixed a bug in libcpluff: When stopping plug-in dependency chains, first call stop function of every plug-in in the chain and then call destroy functions. This makes it possible to do safe two-phase cleanup. Previously the destroy function of a plug-in was called immediately after the stop function of the corresponding plug-in. * Make plug-in dependency loop log message an informational message and not a warning. * Minor documentation changes and corrections. * Build, install and distribute internationalization support files. * Link with libintl if internationalization support needs it. * Unified message string structure and wording. * Include finnish translation (to test internationalization). * Fixed some installation/packaging problems. * Install documentation as part of installation. * Install example source code as part of installation. * Include optional stand-alone build system for example code. * Respect DESTDIR during installation. -- Johannes Lehtinen Wed, 28 Mar 2007 10:24:31 +0300 C-Pluff (0.1.1) alpha * More complete documentation. * Added an example of extensible application (cpfile). * Fixed bug in cpluff-loader: Use empty string for the first argument instead of NULL pointer. * Fixed bug in cp_get_extensions_info: Overwrote memory when returning extensions for a specific extension point. * Fixed bug in plug-in uninstallation: Accessed freed memory when uninstalling a plug-in. * Do not warn about unknown attributes of an extension element because they might be extension point specific data. * Build reference documentation in build directory. * Added a test for inter-plugin symbol usage. -- Johannes Lehtinen Sun, 18 Mar 2007 23:28:59 +0200 C-Pluff (0.1.0) alpha * Initial public release. * Includes incomplete documentation. -- Johannes Lehtinen Thu, 08 Mar 2007 15:45:00 +0200 cpluff-0.1.3/Roadmap.txt0000644000076400001440000000052610605437226012047 00000000000000C-Pluff (0.2.0) alpha * [ ] Introduce C-Pluff C++ API and C++ runtime library. -- Johannes Lehtinen ???

Reason for the problem is not known. The related source code is in examples/cpfile/plugins/special/special.c. The following test code works fine when cross-compiled with MinGW. - clip - #include #include #include #include #include int main(int argc, char *argv[]) { int i; for (i = 1; i < argc; i++) { struct stat s; printf("%s: ", argv[i]); if (stat(argv[i], &s)) { fflush(stdout); perror("stat failed"); } else { if (S_ISDIR(s.st_mode)) { fputs("is directory\n", stdout); } else { fputs("is not directory\n", stdout); } } } return 0; } - clip - cpluff-0.1.3/autogen.sh0000755000076400001440000000102710602161635011714 00000000000000#! /bin/sh # Copyright 2007 Johannes Lehtinen # This shell script is free software; Johannes Lehtinen gives # unlimited permission to copy, distribute and modify it. set -e # Check directory basedir="`dirname "$0"`" if ! test -f "$basedir"/libcpluff/cpluff.h; then echo 'Run autogen.sh in the top level source directory.' 1>&2 exit 1 fi # Generate files in top level directory cd "$basedir" autopoint rm -f ABOUT-NLS test -d auxliary || mkdir auxliary libtoolize --automake -f aclocal -I m4 autoconf autoheader automake -a cpluff-0.1.3/plugin.xsd0000644000076400001440000000740710573761025011747 00000000000000 cpluff-0.1.3/libcpluff/0000777000076400001440000000000010605452557011756 500000000000000cpluff-0.1.3/libcpluff/cpluff.h0000644000076400001440000016003610602141742013314 00000000000000/*------------------------------------------------------------------------- * C-Pluff, a plug-in framework for C * Copyright 2007 Johannes Lehtinen * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included * in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. * IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY * CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. *-----------------------------------------------------------------------*/ /** @file * C-Pluff C API header file. * The elements declared here constitute the C-Pluff C API.

MAX_DOT_GRAPH_HEIGHT = 1024 # The MAX_DOT_GRAPH_DEPTH tag can be used to set the maximum depth of the # graphs generated by dot.

Note that setting this # option to 1 or 2 may greatly reduce the computation time needed for large # code bases. Also note that a graph may be further truncated if the graph's # image dimensions are not sufficient to fit the graph (see MAX_DOT_GRAPH_WIDTH # and MAX_DOT_GRAPH_HEIGHT).

There is a thin main program controlling the plug-in * framework. The main program is responsible for initializing and setting * up the plug-in environment. Most of the application logic is contained in * plug-ins which are independent components and can be developed and * distributed separately. Plug-ins integrate with each other by providing * extension points and extensions. An extension point is a point into which * other plug-ins can attach extensions. An extension can be just * information, expressed in XML format, or the plug-in may also provide * program logic as part of the plug-in runtime library. The framework * provides services for accessing extensions and for managing plug-in * dependencies. * * @image html architecture.png "C-Pluff plug-in architecture" * * @section architectureExtensions Extensions * * The idea behind extension points and extensions is that the extensibility * is not limited only to few fixed plug-in types supported by the * core application. Although the core plug-ins typically define the extension * points for the core application logic, it is possible for any plug-in * to specify additional extension points. * * For example, let us assume that we are developing an extensible text * editor. One extension point defined by core editor plug-in could be * auto-completion extension point. A plug-in providing basic Java source code * support could provide an extension for auto-completing Java code. * Now, while this extension could do basic auto-completion of plain Java code, * it is customary that Java source code also includes embedded documentation, * such as JavaDoc comments and tags, or annotations, such as XDoclet tags, as * part of doc comments. Instead of trying to support all known tags and their * semantics, the plug-in providing basic Java support could define another * extension point for additional plug-ins that know how to perform * auto-completion of different kind of tags in doc comments. * This way the extensibility of the application is not limited to the * extension points defined by the core application but the plug-ins can * incrementally increase the extensibility of the application. */ cpluff-0.1.3/libcpluff/docsrc/mainprog.dox0000644000076400001440000003240010576403211015464 00000000000000/*------------------------------------------------------------------------- * C-Pluff, a plug-in framework for C * Copyright 2007 Johannes Lehtinen * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included * in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. * IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY * CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. *-----------------------------------------------------------------------*/ /** * @page cMainProgram Main program * * @section cMainProgramOverview Overview * * The main program is the part of executable that is located outside the * plug-in framework. The main program is responsible for setting up * the plug-in framework and for loading the desired set of * @ref plugin "plug-ins". The main program should preferably be very * thin, a mere plug-in loader, because it can not fully participate in plug-in * interaction. C-Pluff distribution provides a plug-in loader, * @ref cpluff-loader, which can be used as a generic main program for * arbitrary plug-in collections. * * @section cMainProgramResponsibilities Responsibilities * * The main program has several responsibilities: * * - @ref cMainProgramInitFramework "initializing the plug-in framework" * - @ref cMainProgramCreateContext "creating a plug-in context" * - @ref cMainProgramLoad "loading plug-ins" * - @ref cMainProgramExec "controlling plug-in execution" * - @ref cMainProgramChange "changing plug-in configuration" (opt.) * - @ref cMainProgramDestroyFramework "destroying the plug-in framework" * * @subsection cMainProgramInitFramework Initializing the plug-in framework * * Plug-in framework, or the C-Pluff library, must be initialized before its * services can be used. * Initialization is not a thread-safe operation and should generally be * done by the main program before any additional plug-in framework accessing * threads are started. Initialization is done by calling ::cp_init. * Additionally, the main program can use ::cp_set_fatal_error_handler to register * a function that is called when a fatal error occurs. A fatal error is one * that prevents the framework from continuing operation. For example, * errors in operating system locking operations and a NULL pointer being * passed as an argument which is expected to have a non-NULL value are fatal * erors. * * Here is an example of possible initialization code. * * @code * #include * #include * * void handle_fatal_error(const char *msg) { * * // ... log error, flush logs, send bug report, etc. ... * * fprintf(stderr, "A fatal error occurred: %s\n", msg); * abort(); * } * * void initialize(void) { * cp_status_t status; * * setlocale(LC_ALL, ""); * cp_set_fatal_error_handler(handle_fatal_error); * status = cp_init(); * if (status != CP_OK) { * // ... handle initialization failure ... * } * } * @endcode * * @subsection cMainProgramCreateContext Creating a plug-in context * * A plug-in context represents the co-operation environment of a set of * plug-ins from the perspective of a particular participating plug-in or * the perspective of the main program. From main program perspective, a * plug-in context is a container for a set of plug-ins. A plug-in can interact * with other plug-ins in the same container. * * An extensible application can have more than one plug-in container but * usually one container should suffice. Due to the nature of C programs, * plug-ins deployed to different containers are not very well insulated from * each other. For example, global variables provided by a plug-in in one * container are visible to all plug-ins in all containers. Also, by placing * all plug-ins in the same container they can more efficiently share common * base components which themselves might provide extensibility. * * A main program creates a plug-in context, to be used as a container for * plugins, using ::cp_create_context. * * @code * #include * * cp_context_t *ctx; * * void create_context(void) { * cp_status_t status; * * ctx = cp_create_context(&status); * if (ctx == NULL) { * // ... handle initialization failure ... * } * } * @endcode * * @subsection cMainProgramLoad Loading plug-ins * * An extensible application is made of plug-ins that can be added and removed * dynamically. The plug-ins are loaded by the main program using the services * provided by the framework. The framework provides couple of alternative * ways of loading plug-ins. * * As a lowest level operation, the main program can * load individual plug-ins from known locations using * ::cp_load_plugin_descriptor and ::cp_install_plugin. Here is example code * that loads a set of plug-ins from file system locations listed in a file. * * @code * #include * #include * * extern cp_context_t *ctx; * static const char pluginListFile[] = "/etc/example/plugins.list"; * * void load_plugins(void) { * char plugindir[128]; * FILE *lf; * * // Open plug-in list file * lf = fopen(pluginListFile, "r"); * if (lf == NULL) { * // ... handle loading failure ... * } * * // Load each listed plug-in * while (fgets(plugindir, 128, lf) != NULL) { * cp_plugin_info_t *plugininfo; * cp_status_t status; * int i; * * // Remove possible trailing newline from plug-in location * for (i = 0; plugindir[i + 1] != '\0'; i++); * if (plugindir[i] == '\n') { * plugindir[i] = '\0'; * } * * // Load plug-in descriptor * plugininfo = cp_load_plugin_descriptor(ctx, plugindir, &status); * if (pinfo == NULL) { * // ... handle loading failure ... * } * * // Install plug-in descriptor * status = cp_install_plugin(ctx, plugininfo); * if (status != CP_OK) { * // ... handle loading failure ... * } * * // Release plug-in descriptor information * cp_release_info(ctx, plugininfo); * } * * // Close plug-in list file * fclose(lf); * } * @endcode * * Alternatively, the main program can register and load plug-in collections. * A plug-in collection is a file system directory which includes individual * plug-ins in subdirectories, one plug-in in each subdirectory. Plug-in * collections can be registered with a plug-in context using * ::cp_register_pcollection. Plug-ins of the collection can then be scanned * and loaded using ::cp_scan_plugins. Here is example code loading plug-ins * from a plug-in collection. * * @code * #include * * extern cp_context_t *ctx; * static const char pluginCollectionDir[] = "/etc/example/plugins"; * * void load_plugins(void) { * cp_status_t status; * * status = cp_register_pcollection(ctx, pluginCollectionDir); * if (status != CP_OK) { * // ... handle loading failure ... * } * status = cp_scan_plugins(ctx, 0); * if (status != CP_OK) { * // ... handle loading failure ... * // (notice that some plug-ins might have been loaded) * } * } * @endcode * * @subsection cMainProgramExec Controlling plug-in execution * * The main program controls plug-in execution by starting and stopping * plug-ins and by executing run functions registered by plug-ins. * Additionally, the main program can pass startup arguments to plug-ins. * * When plug-ins are installed they are not yet activated and their * runtime library is not even loaded at that point. The main program * typically activates plug-ins by starting a main plug-in * responsible for user interface or core application logic. This plug-in * then implicitly causes other plug-ins to be activated via dependencies and * by dynamically resolving symbols provided by other plug-ins. Plug-ins * recursively activate each other until all initially needed plug-ins have * been started. Some plug-ins might be activated at a later time when their * functionality is needed, for example due to user action. * * If a plug-in needs to perform background operations, that is operations * executed outside the invocation of plug-in provided interface functions, * then it can either start a new thread or it can register a run function. * A run function is a function that is typically executed as part of the * main loop by the main program. * * The following example code shows how a main program might initialize * plug-in startup arguments using ::cp_set_context_args, start the core * plug-in using ::cp_start_plugin and then execute plug-in run functions * using ::cp_run_plugins. * * @code * #include * * extern cp_context_t *ctx; * static const char corePluginId[] = "org.example.core"; * * void run_plugins(char *argv[]) { * cp_status_t status; * * // Set plug-in startup arguments * cp_set_context_args(ctx, argv); * * // Start the core plug-in, possibly activating other plug-ins as well * status = cp_start_plugin(ctx, corePluginId); * if (status != CP_OK) { * // ... handle startup failure ... * } * * // Execute plug-ins until there is no more work to be done * cp_run_plugins(ctx); * } * * int main(int argc, char *argv[]) { * // ... do initialization and load plug-ins ... * * run_plugins(argv); * * // ... do destruction ... * } * @endcode * * Alternatively, if the main program has some operations it must perform * as part of the main loop, the call to ::cp_run_plugins can be replaced * by code using ::cp_run_plugins_step like in the following example. * * @code * void mainloop(void) { * int finished = 0; * * while (!finished) { * // ... do main program specific operations ... * * finished = !cp_run_plugins_step(ctx); * } * } * @endcode * * @subsection cMainProgramChange Changing plug-in configuration * * C-Pluff has been designed to allow dynamic changes to the plug-in * configuration, that is plug-ins being added or removed without shutting * down the application or the framework. It is the responsibility of the * main program to manage such changes if the application is to support * dynamic configuration changes. * * Adding plug-ins is straightforward because there is no need to * consider dependencies of active plug-ins. For example, if one uses * plug-in collections as introduced above then new plug-ins can be * deployed under the plug-in collection directory while the application is * running and the main program can load them incrementally by calling * ::cp_scan_plugins again. This call might be activated by some user interface * element, for example a plug-in manager component which just downloaded and * installed new plug-ins as requested by the user. The flags * #CP_SP_STOP_ALL_ON_INSTALL and #CP_SP_RESTART_ACTIVE * orred together can be used to cause all active plug-ins to be restarted * if they do not otherwise notice the extensions provided by new plug-ins. * * Upgrading plug-ins is almost as straightforward because the C-Pluff * framework manages plug-in dependencies (assuming the plug-ins have * declared their dependencies properly). The new version of a plug-in * can be deployed under the plug-in collection directory in a * new subdirectory parallel to the old version while the application is * running. The main program can then call ::cp_scan_plugins with * #CP_SP_UPGRADE and #CP_SP_RESTART_ACTIVE orred together. This will stop * the old version of the upgraded plug-in (implicitly stopping all plug-ins * that depend on it), unload the plug-in from the framework, install the * new version of the plug-in and finally restart plug-ins that were * active before the operation. The old version of the plug-in can now * be removed from the plug-in collection. Again, #CP_SP_STOP_ALL_ON_UPGRADE * can be added to restart all active plug-ins. * * Deleting plug-ins must be done by first stopping and unloading the * plug-in to be deleted using ::cp_uninstall_plugin. The the plug-in can * be removed from the plug-in collection. * * @subsection cMainProgramDestroyFramework Destroying the plug-in framework * * The plug-in framework can be destroyed and all resources released by * calling ::cp_destroy as many times as ::cp_init has been called. This * is not a thread-safe operation and should generally be done by the main * program just before application exits. The destroy function * stops and unloads all plug-ins and destroys all plug-in contexts before * destroying the core framework. * * Individual plug-in contexts can be destroyed by calling * ::cp_destroy_context. The destroy function stops and unloads all plug-ins * before destroying the context itself. */ cpluff-0.1.3/libcpluff/docsrc/plugin.dox0000644000076400001440000004054610602377202015160 00000000000000/*------------------------------------------------------------------------- * C-Pluff, a plug-in framework for C * Copyright 2007 Johannes Lehtinen * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included * in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. * IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY * CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. *-----------------------------------------------------------------------*/ /** * @page plugin Plug-in * * @section pluginOverview Overview * * Plug-in is the core element of an extensible application.

It includes * information about the contents of the plug-in, the features provided by * the plug-in, plug-in version information and static dependencies of the * plug-in. Most of the elements are optional. Most of the descriptor * information described here is available to software via * @ref cp_plugin_info_t structure. The plug-in descriptor must be located * in the plug-in directory as @c plugin.xml. * * The formal declaration of plug-in descriptor is available as * XML Schema Definition in @c plugin.xsd located in the top level source * directory.

*
* * @subsubsection pluginDescPlugin plugin * * This is the top level element of the plug-in descriptor. It can have * following attributes. * * - @a id: A mandatory unique identifier for the plug-in. Plug-in identifiers * should preferably be generated using a reversed DNS domain name as * prefix to prevent identifier conflicts. * - @a name: An optional human-readable name for the plug-in. * - @a version: An optional version number for the plug-in. Version numbers * are used for checking compatibility when resolving versioned plug-in * dependencies. See also information about * @ref pluginVersions "plug-in versions". * - @a provider-name: The name of the plug-in provider or author. Optional. * * This element can contain following elements. * * - @ref pluginDescPluginBWC "backwards-compatibility": Optional information about backwards * compatibility of this plug-in version. * - @ref pluginDescPluginRequires "requires": Information about static plug-in dependencies. Can be omitted * if the plug-in does not have static dependencies. * - @ref pluginDescPluginRuntime "runtime": Information about the plug-in runtime library. Can be omitted * if the plug-in does not have a runtime library but only data. * - @ref pluginDescPluginEP "extension-point": Information about extension points provided by the * plug-in. This element is repeated if there are multiple extension points * and omitted if there are none. * - @ref pluginDescPluginE "extension": Information about extensions provided by the plug-in. * This element is repeated if there are multiple extensions and omitted * if there are none. * * @subsubsection pluginDescPluginBWC backwards-compatibility * * This element includes optional information about the backwards compatibility * of this plug-in version. It can have following attributes. * * - @a abi: Backwards compatibility of the application binary interface (ABI) * of the plug-in. ABI includes any public symbols exported by the plug-in, * data structures associated with exported symbols and any extension points * provided by the plug-in. The ABI of the current plug-in version is * backwards compatible with any plug-in version from the version specified * here to the current version. This information is used when resolving * versioned plug-in dependencies. See also information about * @ref pluginVersions "plug-in versions". * - @a api: Backwards compatibility of the application programming interface * (API) of the plug-in. API compatibility means that source code developed * against one version of the plug-in also compiles against another version * of the plug-in. This information is not used by framework but it can be * used by a developer developing dependent plug-ins. * * These apply to plug-ins that provide header files and runtime libraries. * For example, a plug-in might export global functions to other plug-ins or it * might provide an extension point where an extension installed by other * plug-in must conform to data structures defined by the plug-in. * Both attributes are optional. * * @subsubsection pluginDescPluginRequires requires * * This element includes information about static plug-in dependencies. * It can be omitted if there are no dependencies. It can contain following * elements. * * - @ref pluginDescPluginReqCP "c-pluff": An optional version dependency * on the C-Pluff implementation. * - @ref pluginDescPluginReqImport "import": Declares a static dependency * on other plug-in. This element is repeated if there are multiple * dependencies and omitted if there are none. * * @subsubsection pluginDescPluginReqCP c-pluff * * This element declares a version dependency on the C-Pluff * implementation. It can be used to ensure that the plug-in is not loaded by * incompatible C-Pluff version. It has the following attribute. * * - @a version: The required version of the C-Pluff implementation. * This is used when resolving the plug-in. It is checked that the used * C-Pluff implementation is backwards compatible with the version specified * here when it comes to the application binary interface (ABI) of C-Pluff. * * @subsubsection pluginDescPluginReqImport import * * This element declares a static dependency on other plug-in. It must be * used when a plug-in uses global symbols or data from other plug-in or when * a plug-in uses an extension point defined by other plug-in or whenever some * other plug-in needs to be there for the plug-in to work. The framework takes * care of resolving and starting the dependencies whenever the plug-in is * resolved or started. * * This element can have following attributes. * * - @a plugin: The identifier of the imported plug-in. * - @a version: An optional version dependency on the imported plug-in. * The plug-in can be resolved only if the version of the imported plug-in * is backwards compatible with the version specified here when it comes * to the application binary interface (ABI) of the imported plug-in. * - @a optional: Is the import optional or not ("true" or "false"). Default is * false, a mandatory import. * An optional import behaves just like the mandatory import as long as the * imported plug-in is present. However, if it is not present then the * import is ignored. Optional import can be used if the plug-in works * in limited capacity even without the specified plug-in. * * @subsubsection pluginDescPluginRuntime runtime * * This element contains information about the plug-in runtime library. It is * omitted if the plug-in does not have a runtime library but contains only * data. It can have following attributes. * * - @a library: The name of the plug-in runtime library in the plug-in * directory. A platform specific extension (for example, ".so" or ".dll") * is added to the value specified here when loading the library. * - @a funcs: The functions to be used to create an instance of the plug-in * runtime. This attribute is optional. It is needed if the plug-in has * a start or stop function. The value specified here is a name of an * exported symbol which contains a pointer to @ref cp_plugin_runtime_t * structure. * * @subsubsection pluginDescPluginEP extension-point * * This element defines an extension point provided by the plug-in. * It can have following attributes. * * - @a id: The local identifier of the extension point. The value specified * here is prefixed with the identifier of the plug-in and dot to construct * the global identifier of the extension point. * - @a name: An optional human-readable name describing the use of the * extension point. * - @a schema: An optional path to the extension point XML schema in * the plug-in directory. This information is not currently used by the * framework. But it can be used by a developer to determine what information * should be provided by extensions attached to this extension point. * * @subsubsection pluginDescPluginE extension * * This element defines an extension installed into a specified extension * point provided by the defining plug-in or some other plug-in. * It can have following attributes. * * - @a point: The global identifier of the associated extension point. * - @a id: An optional local identifier for the extension. The value specified * here is prefixed with the identifier of the plug-in and dot to construct * the global identifier for the extension. * - @a name: An optional human-readable name describing the extension. * * The extension element can contain XML elements specific to the associated * extension point (conforming to the schema defined by the extension point). * * @subsection pluginRuntime Plug-in runtime library * * A plug-in runtime library is an optional plug-in element. Plug-ins only * supplying static data in form of XML data and files do not need a runtime * library. However, a typical plug-in does provide program logic as well. * * The plug-in runtime library includes all program logic and program * data provided by the plug-in. It is simply a shared library, or a * dynamically linked library, which is linked in to the application when * the plug-in is started. When plug-in is unloaded, the runtime library is * unloaded as well. The framework has been designed to manage dependencies * so that unloading of the runtime library does not cause problems, provided * that plug-ins behave properly. * * A plug-in can expose functionality to other plug-ins either as exported * global symbols that are directly resolved by other plug-ins or by supplying * extensions. When other plug-ins are directly using exported symbols the * plug-in acts just like any standard shared library. Nothing special there. * The more interesting case is exposing functionality as extensions. Because * the extension is registered at a specific extension point, the logic in * other plug-ins can use the extension and the associated program logic even * if they are not aware of the existence of the extension supplying plug-in. * * The extension points accepting program logic as extensions define a way * to specify the name of the symbol pointing to the supplied logic. This is * typically an attribute of an XML element contained in the extension * definition. The plug-in supplying the extension can then export the program * logic as a global symbol with arbitrary name and then place the name of the * symbol in extension data. Alternatively, the plug-in can define a virtual * symbol at runtime using ::cp_define_symbol. Other plug-ins that are using * extensions registered at the extension point can then resolve the named * symbol using ::cp_resolve_symbol at runtime. The framework automatically * creates a dependency from the symbol using plug-in to the symbol supplying * plug-in to prevent failures in case the symbol supplying plug-in is stopped * or unloaded. * * @subsection pluginData Static plug-in data * * Plug-in can supply static data to other plug-ins using at least two * different mechanisms. A plug-in can easily provide static XML data as part * of extension elements. Additionally, a plug-in directory can contain * files that may be accessed by other plug-ins. Currently the platform does * not provide assistance in accessing data files provided by other plug-ins. * However, a plug-in can locate the plug-in directory and thus any included * data files by using plug-in path available in @ref cp_plugin_info_t * structure of the data providing plug-in. */ cpluff-0.1.3/kazlib/0000777000076400001440000000000010605452557011264 500000000000000cpluff-0.1.3/kazlib/list.c0000644000076400001440000004710310546664066012330 00000000000000/* * List Abstract Data Type * Copyright (C) 1997 Kaz Kylheku * * Free Software License: * * All rights are reserved by the author, with the following exceptions: * Permission is granted to freely reproduce and distribute this software, * possibly in exchange for a fee, provided that this copyright notice appears * intact.

C-Pluff C API Documentation

0.1.3

This is reference documentation for the C-Pluff C API. C-Pluff is a plug-in framework for C programs. It has been strongly inspired by the Java plug-in framework in Eclipse. C-Pluff focuses on providing core services for plug-in interaction and plug-in management. It aims to be platform neutral and supports dynamic changes to plug-in configuration without stopping the whole application or framework. It does not yet provide special facilities for distribution such as signed plug-in packages or remote plug-in repositories but it is possible to build such features on top of the current framework.

Here are links to main topics.

For a "quick start guide" in developing C-Pluff based applications, see the example in the examples directory of the source distribution.

The latest version of the framework implementation and documentation is available at C-Pluff web site.

This documentation has been generated from the C-Pluff source code using Doxygen.

Plug-in architecture

Overview

The plug-in architecture supported by C-Pluff is presented in the following figure. There is a thin main program controlling the plug-in framework. The main program is responsible for initializing and setting up the plug-in environment. Most of the application logic is contained in plug-ins which are independent components and can be developed and distributed separately. Plug-ins integrate with each other by providing extension points and extensions. An extension point is a point into which other plug-ins can attach extensions. An extension can be just information, expressed in XML format, or the plug-in may also provide program logic as part of the plug-in runtime library. The framework provides services for accessing extensions and for managing plug-in dependencies.

C-Pluff plug-in architecture

Extensions

The idea behind extension points and extensions is that the extensibility is not limited only to few fixed plug-in types supported by the core application. Although the core plug-ins typically define the extension points for the core application logic, it is possible for any plug-in to specify additional extension points.

For example, let us assume that we are developing an extensible text editor. One extension point defined by core editor plug-in could be auto-completion extension point. A plug-in providing basic Java source code support could provide an extension for auto-completing Java code. Now, while this extension could do basic auto-completion of plain Java code, it is customary that Java source code also includes embedded documentation, such as JavaDoc comments and tags, or annotations, such as XDoclet tags, as part of doc comments. Instead of trying to support all known tags and their semantics, the plug-in providing basic Java support could define another extension point for additional plug-ins that know how to perform auto-completion of different kind of tags in doc comments. This way the extensibility of the application is not limited to the extension points defined by the core application but the plug-ins can incrementally increase the extensibility of the application.

Main program

Overview

The main program is the part of executable that is located outside the plug-in framework. The main program is responsible for setting up the plug-in framework and for loading the desired set of plug-ins. The main program should preferably be very thin, a mere plug-in loader, because it can not fully participate in plug-in interaction. C-Pluff distribution provides a plug-in loader, cpluff-loader, which can be used as a generic main program for arbitrary plug-in collections.

Responsibilities

The main program has several responsibilities:

Initializing the plug-in framework

Plug-in framework, or the C-Pluff library, must be initialized before its services can be used. Initialization is not a thread-safe operation and should generally be done by the main program before any additional plug-in framework accessing threads are started. Initialization is done by calling cp_init. Additionally, the main program can use cp_set_fatal_error_handler to register a function that is called when a fatal error occurs. A fatal error is one that prevents the framework from continuing operation. For example, errors in operating system locking operations and a NULL pointer being passed as an argument which is expected to have a non-NULL value are fatal erors.

Here is an example of possible initialization code.

 #include <locale.h>
 #include <cpluff.h>

 void handle_fatal_error(const char *msg) {

   // ... log error, flush logs, send bug report, etc. ...

   fprintf(stderr, "A fatal error occurred: %s\n", msg);
   abort();
 }

 void initialize(void) {
   cp_status_t status;

   setlocale(LC_ALL, "");
   cp_set_fatal_error_handler(handle_fatal_error);
   status = cp_init();
   if (status != CP_OK) {
     // ... handle initialization failure ...
   }

Creating a plug-in context

A plug-in context represents the co-operation environment of a set of plug-ins from the perspective of a particular participating plug-in or the perspective of the main program. From main program perspective, a plug-in context is a container for a set of plug-ins. A plug-in can interact with other plug-ins in the same container.

An extensible application can have more than one plug-in container but usually one container should suffice. Due to the nature of C programs, plug-ins deployed to different containers are not very well insulated from each other. For example, global variables provided by a plug-in in one container are visible to all plug-ins in all containers. Also, by placing all plug-ins in the same container they can more efficiently share common base components which themselves might provide extensibility.

A main program creates a plug-in context, to be used as a container for plugins, using cp_create_context.

 #include <cpluff.h>

 cp_context_t *ctx;

 void create_context(void) {
   cp_status_t status;

   ctx = cp_create_context(&status);
   if (ctx == NULL) {
     // ... handle initialization failure ...
   }
 }

Loading plug-ins

An extensible application is made of plug-ins that can be added and removed dynamically. The plug-ins are loaded by the main program using the services provided by the framework. The framework provides couple of alternative ways of loading plug-ins.

As a lowest level operation, the main program can load individual plug-ins from known locations using cp_load_plugin_descriptor and cp_install_plugin. Here is example code that loads a set of plug-ins from file system locations listed in a file.

 #include <stdio.h>
 #include <cpluff.h>

 extern cp_context_t *ctx;
 static const char pluginListFile[] = "/etc/example/plugins.list";

 void load_plugins(void) {
   char plugindir[128];
   FILE *lf;

   // Open plug-in list file
   lf = fopen(pluginListFile, "r");
   if (lf == NULL) {
     // ... handle loading failure ...
   }

   // Load each listed plug-in
   while (fgets(plugindir, 128, lf) != NULL) {
     cp_plugin_info_t *plugininfo;
     cp_status_t status;
     int i;

     // Remove possible trailing newline from plug-in location
     for (i = 0; plugindir[i + 1] != '\0'; i++);
     if (plugindir[i] == '\n') {
       plugindir[i] = '\0';
     }

     // Load plug-in descriptor
     plugininfo = cp_load_plugin_descriptor(ctx, plugindir, &status);
     if (pinfo == NULL) {
       // ... handle loading failure ...
     }

     // Install plug-in descriptor
     status = cp_install_plugin(ctx, plugininfo);
     if (status != CP_OK) {
       // ... handle loading failure ...
     }

     // Release plug-in descriptor information
     cp_release_info(ctx, plugininfo);
   }

   // Close plug-in list file
   fclose(lf);
 }

Alternatively, the main program can register and load plug-in collections. A plug-in collection is a file system directory which includes individual plug-ins in subdirectories, one plug-in in each subdirectory. Plug-in collections can be registered with a plug-in context using cp_register_pcollection. Plug-ins of the collection can then be scanned and loaded using cp_scan_plugins. Here is example code loading plug-ins from a plug-in collection.

 #include <cpluff.h>

 extern cp_context_t *ctx;
 static const char pluginCollectionDir[] = "/etc/example/plugins";

 void load_plugins(void) {
   cp_status_t status;

   status = cp_register_pcollection(ctx, pluginCollectionDir);
   if (status != CP_OK) {
     // ... handle loading failure ...
   }
   status = cp_scan_plugins(ctx, 0);
   if (status != CP_OK) {
     // ... handle loading failure ...
     // (notice that some plug-ins might have been loaded)
   }
 }

Controlling plug-in execution

The main program controls plug-in execution by starting and stopping plug-ins and by executing run functions registered by plug-ins. Additionally, the main program can pass startup arguments to plug-ins.

When plug-ins are installed they are not yet activated and their runtime library is not even loaded at that point. The main program typically activates plug-ins by starting a main plug-in responsible for user interface or core application logic. This plug-in then implicitly causes other plug-ins to be activated via dependencies and by dynamically resolving symbols provided by other plug-ins. Plug-ins recursively activate each other until all initially needed plug-ins have been started. Some plug-ins might be activated at a later time when their functionality is needed, for example due to user action.

If a plug-in needs to perform background operations, that is operations executed outside the invocation of plug-in provided interface functions, then it can either start a new thread or it can register a run function. A run function is a function that is typically executed as part of the main loop by the main program.

The following example code shows how a main program might initialize plug-in startup arguments using cp_set_context_args, start the core plug-in using cp_start_plugin and then execute plug-in run functions using cp_run_plugins.

 #include <cpluff.h>

 extern cp_context_t *ctx;
 static const char corePluginId[] = "org.example.core";

 void run_plugins(char *argv[]) {
   cp_status_t status;

   // Set plug-in startup arguments
   cp_set_context_args(ctx, argv);

   // Start the core plug-in, possibly activating other plug-ins as well
   status = cp_start_plugin(ctx, corePluginId);
   if (status != CP_OK) {
     // ... handle startup failure ...
   }

   // Execute plug-ins until there is no more work to be done
   cp_run_plugins(ctx);
 }

 int main(int argc, char *argv[]) {
   // ... do initialization and load plug-ins ...

   run_plugins(argv);

   // ... do destruction ...
 }

Alternatively, if the main program has some operations it must perform as part of the main loop, the call to cp_run_plugins can be replaced by code using cp_run_plugins_step like in the following example.

 void mainloop(void) {
   int finished = 0;

   while (!finished) {
     // ... do main program specific operations ...

     finished = !cp_run_plugins_step(ctx);
   }
 }

Changing plug-in configuration

C-Pluff has been designed to allow dynamic changes to the plug-in configuration, that is plug-ins being added or removed without shutting down the application or the framework. It is the responsibility of the main program to manage such changes if the application is to support dynamic configuration changes.

Adding plug-ins is straightforward because there is no need to consider dependencies of active plug-ins. For example, if one uses plug-in collections as introduced above then new plug-ins can be deployed under the plug-in collection directory while the application is running and the main program can load them incrementally by calling cp_scan_plugins again. This call might be activated by some user interface element, for example a plug-in manager component which just downloaded and installed new plug-ins as requested by the user. The flags CP_SP_STOP_ALL_ON_INSTALL and CP_SP_RESTART_ACTIVE orred together can be used to cause all active plug-ins to be restarted if they do not otherwise notice the extensions provided by new plug-ins.

Upgrading plug-ins is almost as straightforward because the C-Pluff framework manages plug-in dependencies (assuming the plug-ins have declared their dependencies properly). The new version of a plug-in can be deployed under the plug-in collection directory in a new subdirectory parallel to the old version while the application is running. The main program can then call cp_scan_plugins with CP_SP_UPGRADE and CP_SP_RESTART_ACTIVE orred together. This will stop the old version of the upgraded plug-in (implicitly stopping all plug-ins that depend on it), unload the plug-in from the framework, install the new version of the plug-in and finally restart plug-ins that were active before the operation. The old version of the plug-in can now be removed from the plug-in collection. Again, CP_SP_STOP_ALL_ON_UPGRADE can be added to restart all active plug-ins.

Deleting plug-ins must be done by first stopping and unloading the plug-in to be deleted using cp_uninstall_plugin. The the plug-in can be removed from the plug-in collection.

Destroying the plug-in framework

The plug-in framework can be destroyed and all resources released by calling cp_destroy as many times as cp_init has been called. This is not a thread-safe operation and should generally be done by the main program just before application exits. The destroy function stops and unloads all plug-ins and destroys all plug-in contexts before destroying the core framework.

Individual plug-in contexts can be destroyed by calling cp_destroy_context. The destroy function stops and unloads all plug-ins before destroying the context itself.

Plug-in

Overview

Plug-in is the core element of an extensible application. The extensions and also the main application logic are implemented as plug-ins. Plug-ins can be developed, distributed and deployed independently, subject to inter-plugin dependencies. Deploying a new plug-in does not require recompilation or relinking if the operating system platform supports required dynamic linking facilities.

Structure

A plug-in includes the following structural elements.

Plug-in descriptor

A plug-in descriptor is an XML document describing a plug-in. It includes information about the contents of the plug-in, the features provided by the plug-in, plug-in version information and static dependencies of the plug-in. Most of the elements are optional. Most of the descriptor information described here is available to software via cp_plugin_info_t structure. The plug-in descriptor must be located in the plug-in directory as plugin.xml.

The formal declaration of plug-in descriptor is available as XML Schema Definition in plugin.xsd located in the top level source directory. Currently there is no namespace associated with the plug-in descriptor. Here is an example of a plug-in descriptor. Click element name to jump into documentation for that element.

 <plugin id="org.c-pluff.example" name="Example Plug-in" version="0.3.2" provider-name="Johannes Lehtinen">
     <backwards-compatibility abi="0.3" api="0.2.8"/>
     <requires>
         <c-pluff version="0.1"/>
         <import plugin="org.c-pluff.util" version="0.2"/>
         <import plugin="org.c-pluff.extra" optional="true"/> 
     </requires>
     <runtime library="libruntime" funcs="org_cpluff_example_funcs"/>
     <extension-point id="editors" name="Text Editors" schema="editors_schema.xsd"/>
     <extension-point id="url-families"/>
     <extension point="org.c-pluff.util.archivers" id="tar" name="Tar Archiver Support">
         <type random-access="false"/>
         <exec bin="tar"/>
     </extension>
     <extension point="org.c-pluff.example.editors>
         <editor name="Text Editor" runtime="org_cpluff_example_txteditor_runtime">
             <file-types>
                 <file-type mime-type="text/plain"/>
             </file-types>
         </editor>
     </extension>
 </plugin>

A descriptor can also be much simpler, depending on the plug-in. Here is an example of a minimal descriptor (of a useless plug-in).

 <plugin id="org.c-pluff.useless"/>

plugin

This is the top level element of the plug-in descriptor. It can have following attributes.

  • id: A mandatory unique identifier for the plug-in. Plug-in identifiers should preferably be generated using a reversed DNS domain name as prefix to prevent identifier conflicts.
  • name: An optional human-readable name for the plug-in.
  • version: An optional version number for the plug-in. Version numbers are used for checking compatibility when resolving versioned plug-in dependencies. See also information about plug-in versions.
  • provider-name: The name of the plug-in provider or author. Optional.

This element can contain following elements.

  • backwards-compatibility: Optional information about backwards compatibility of this plug-in version.
  • requires: Information about static plug-in dependencies. Can be omitted if the plug-in does not have static dependencies.
  • runtime: Information about the plug-in runtime library. Can be omitted if the plug-in does not have a runtime library but only data.
  • extension-point: Information about extension points provided by the plug-in. This element is repeated if there are multiple extension points and omitted if there are none.
  • extension: Information about extensions provided by the plug-in. This element is repeated if there are multiple extensions and omitted if there are none.

backwards-compatibility

This element includes optional information about the backwards compatibility of this plug-in version. It can have following attributes.

  • abi: Backwards compatibility of the application binary interface (ABI) of the plug-in. ABI includes any public symbols exported by the plug-in, data structures associated with exported symbols and any extension points provided by the plug-in. The ABI of the current plug-in version is backwards compatible with any plug-in version from the version specified here to the current version. This information is used when resolving versioned plug-in dependencies. See also information about plug-in versions.
  • api: Backwards compatibility of the application programming interface (API) of the plug-in. API compatibility means that source code developed against one version of the plug-in also compiles against another version of the plug-in. This information is not used by framework but it can be used by a developer developing dependent plug-ins.

These apply to plug-ins that provide header files and runtime libraries. For example, a plug-in might export global functions to other plug-ins or it might provide an extension point where an extension installed by other plug-in must conform to data structures defined by the plug-in. Both attributes are optional.

requires

This element includes information about static plug-in dependencies. It can be omitted if there are no dependencies. It can contain following elements.

  • c-pluff: An optional version dependency on the C-Pluff implementation.
  • import: Declares a static dependency on other plug-in. This element is repeated if there are multiple dependencies and omitted if there are none.

c-pluff

This element declares a version dependency on the C-Pluff implementation. It can be used to ensure that the plug-in is not loaded by incompatible C-Pluff version. It has the following attribute.

  • version: The required version of the C-Pluff implementation. This is used when resolving the plug-in. It is checked that the used C-Pluff implementation is backwards compatible with the version specified here when it comes to the application binary interface (ABI) of C-Pluff.

import

This element declares a static dependency on other plug-in. It must be used when a plug-in uses global symbols or data from other plug-in or when a plug-in uses an extension point defined by other plug-in or whenever some other plug-in needs to be there for the plug-in to work. The framework takes care of resolving and starting the dependencies whenever the plug-in is resolved or started.

This element can have following attributes.

  • plugin: The identifier of the imported plug-in.
  • version: An optional version dependency on the imported plug-in. The plug-in can be resolved only if the version of the imported plug-in is backwards compatible with the version specified here when it comes to the application binary interface (ABI) of the imported plug-in.
  • optional: Is the import optional or not ("true" or "false"). Default is false, a mandatory import. An optional import behaves just like the mandatory import as long as the imported plug-in is present. However, if it is not present then the import is ignored. Optional import can be used if the plug-in works in limited capacity even without the specified plug-in.

runtime

This element contains information about the plug-in runtime library. It is omitted if the plug-in does not have a runtime library but contains only data. It can have following attributes.

  • library: The name of the plug-in runtime library in the plug-in directory. A platform specific extension (for example, ".so" or ".dll") is added to the value specified here when loading the library.
  • funcs: The functions to be used to create an instance of the plug-in runtime. This attribute is optional. It is needed if the plug-in has a start or stop function. The value specified here is a name of an exported symbol which contains a pointer to cp_plugin_runtime_t structure.

extension-point

This element defines an extension point provided by the plug-in. It can have following attributes.

  • id: The local identifier of the extension point. The value specified here is prefixed with the identifier of the plug-in and dot to construct the global identifier of the extension point.
  • name: An optional human-readable name describing the use of the extension point.
  • schema: An optional path to the extension point XML schema in the plug-in directory. This information is not currently used by the framework. But it can be used by a developer to determine what information should be provided by extensions attached to this extension point.

extension

This element defines an extension installed into a specified extension point provided by the defining plug-in or some other plug-in. It can have following attributes.

  • point: The global identifier of the associated extension point.
  • id: An optional local identifier for the extension. The value specified here is prefixed with the identifier of the plug-in and dot to construct the global identifier for the extension.
  • name: An optional human-readable name describing the extension.

The extension element can contain XML elements specific to the associated extension point (conforming to the schema defined by the extension point).

Plug-in runtime library

A plug-in runtime library is an optional plug-in element. Plug-ins only supplying static data in form of XML data and files do not need a runtime library. However, a typical plug-in does provide program logic as well.

The plug-in runtime library includes all program logic and program data provided by the plug-in. It is simply a shared library, or a dynamically linked library, which is linked in to the application when the plug-in is started. When plug-in is unloaded, the runtime library is unloaded as well. The framework has been designed to manage dependencies so that unloading of the runtime library does not cause problems, provided that plug-ins behave properly.

A plug-in can expose functionality to other plug-ins either as exported global symbols that are directly resolved by other plug-ins or by supplying extensions. When other plug-ins are directly using exported symbols the plug-in acts just like any standard shared library. Nothing special there. The more interesting case is exposing functionality as extensions. Because the extension is registered at a specific extension point, the logic in other plug-ins can use the extension and the associated program logic even if they are not aware of the existence of the extension supplying plug-in.

The extension points accepting program logic as extensions define a way to specify the name of the symbol pointing to the supplied logic. This is typically an attribute of an XML element contained in the extension definition. The plug-in supplying the extension can then export the program logic as a global symbol with arbitrary name and then place the name of the symbol in extension data. Alternatively, the plug-in can define a virtual symbol at runtime using cp_define_symbol. Other plug-ins that are using extensions registered at the extension point can then resolve the named symbol using cp_resolve_symbol at runtime. The framework automatically creates a dependency from the symbol using plug-in to the symbol supplying plug-in to prevent failures in case the symbol supplying plug-in is stopped or unloaded.

Static plug-in data

Plug-in can supply static data to other plug-ins using at least two different mechanisms. A plug-in can easily provide static XML data as part of extension elements. Additionally, a plug-in directory can contain files that may be accessed by other plug-ins. Currently the platform does not provide assistance in accessing data files provided by other plug-ins. However, a plug-in can locate the plug-in directory and thus any included data files by using plug-in path available in cp_plugin_info_t structure of the data providing plug-in.

Symbol visibility
[Defines]

Detailed Description

Macros for controlling inter-module symbol visibility and linkage.

These macros have platform specific values. CP_EXPORT, CP_IMPORT and CP_HIDDEN can be reused by plug-in implementations for better portability. The complexity is mostly due to Windows DLL exports and imports.

Each module should usually define its own macro to declare API symbols with CP_EXPORT and CP_IMPORT as necessary. For example, a mobule could define a macro MY_API in the API header file as follows.

 #ifndef MY_API
 #  define MY_API CP_IMPORT
 #endif

By default the API symbols would then be marked for import which is correct when client modules are including the API header file. When compiling the module itself the option -DMY_API=CP_EXPORT would be passed to the compiler to override the API header file and to mark the API symbols for export. The overriding definition could also be included in module source files or in an internal header file before including the API header file.


Defines

#define CP_HIDDEN

Define Documentation

#define CP_EXPORT

Declares a symbol to be exported for inter-module usage.

When compiling the module which defines the symbol this macro should be placed at the start of the symbol declaration to ensure that the symbol is exported to other modules. However, when compiling other modules the declaration of the symbol should start with CP_IMPORT. See the example of how to do this.

#define CP_IMPORT

Declares a symbol to be imported from another module.

When compiling a module which uses the symbol this macro should be placed at the start of the symbol declaration to ensure that the symbol is imported from the defining module. However, when compiling the defining module the declaration of the symbol should start with CP_EXPORT. See the example of how to do this.

#define CP_HIDDEN

Declares a symbol hidden from other modules.

This macro should be placed at the start of the symbol declaration to hide the symbol from other modules (if supported by the platform). This macro is not intended to be used with symbols declared as "static" which are already internal to the object file. Some platforms do not support hiding of symbols and therefore unique prefixes should be used for global symbols internal to the module even when they are declared using this macro.

Enumeration Type Documentation

enum cp_status_t

An enumeration of status codes returned by API functions.

Most of the interface functions return a status code. The returned status code either indicates successful completion of the operation or some specific kind of error. Some functions do not return a status code because they never fail.

Enumerator:
CP_OK  Operation was performed successfully (equals to zero).
CP_ERR_RESOURCE  Not enough memory or other operating system resources available.
CP_ERR_UNKNOWN  The specified object is unknown to the framework.
CP_ERR_IO  An I/O error occurred.
CP_ERR_MALFORMED  Malformed plug-in descriptor was encountered when loading a plug-in.
CP_ERR_CONFLICT  Plug-in or symbol conflicts with another plug-in or symbol.
CP_ERR_DEPENDENCY  Plug-in dependencies could not be satisfied.
CP_ERR_RUNTIME  Plug-in runtime signaled an error.

enum cp_plugin_state_t

An enumeration of possible plug-in states.

Plug-in states are controlled by plug-in management functions. Plug-in states can be observed by registering a plug-in listener function or by calling cp_get_plugin_state.

See also:
cp_plugin_listener_t

cp_get_plugin_state

Enumerator:
CP_PLUGIN_UNINSTALLED  Plug-in is not installed.

No plug-in information has been loaded.

CP_PLUGIN_INSTALLED  Plug-in is installed.

At this stage the plug-in information has been loaded but its dependencies to other plug-ins has not yet been resolved. The plug-in runtime has not been loaded yet. The extension points and extensions provided by the plug-in have been registered.

CP_PLUGIN_RESOLVED  Plug-in dependencies have been resolved.

At this stage it has been verified that the dependencies of the plug-in are satisfied and the plug-in runtime has been loaded but it is not active (it has not been started or it has been stopped). Plug-in is resolved when a dependent plug-in is being resolved or before the plug-in is started. Plug-in is put back to installed stage if its dependencies are being uninstalled.

CP_PLUGIN_STARTING  Plug-in is starting.

The plug-in has been resolved and the start function (if any) of the plug-in runtime is about to be called. A plug-in is started when explicitly requested by the main program or when a dependent plug-in is about to be started or when a dynamic symbol defined by the plug-in is being resolved. This state is omitted and the state changes directly from resolved to active if the plug-in runtime does not define a start function.

CP_PLUGIN_STOPPING  Plug-in is stopping.

The stop function (if any) of the plug-in runtime is about to be called. A plug-in is stopped if the start function fails or when stopping is explicitly requested by the main program or when its dependencies are being stopped. This state is omitted and the state changes directly from active to resolved if the plug-in runtime does not define a stop function.

CP_PLUGIN_ACTIVE  Plug-in has been successfully started and it has not yet been stopped.

enum cp_log_severity_t

An enumeration of possible message severities for framework logging.

These constants are used when passing a log message to a logger function and when registering a logger function.

Enumerator:
CP_LOG_DEBUG  Used for detailed debug messages.
CP_LOG_INFO  Used for informational messages such as plug-in state changes.
CP_LOG_WARNING  Used for messages warning about possible problems.
CP_LOG_ERROR  Used for messages reporting errors.

Typedef Documentation

typedef struct cp_context_t cp_context_t

A plug-in context represents the co-operation environment of a set of plug-ins from the perspective of a particular participating plug-in or the perspective of the main program.

It is used as an opaque handle to the shared resources but the framework also uses the context to identify the plug-in or the main program invoking framework functions. Therefore a plug-in should not generally expose its context instance to other plug-ins or the main program and neither should the main program expose its context instance to plug-ins. The main program creates plug-in contexts using cp_create_context and plug-ins receive their plug-in contexts via cp_plugin_runtime_t::create.

Typedef Documentation

typedef void(*) cp_plugin_listener_func_t(const char *plugin_id, cp_plugin_state_t old_state, cp_plugin_state_t new_state, void *user_data)

A listener function called synchronously after a plugin state change.

The function should return promptly. Library initialization, plug-in context management, plug-in management, listener registration (cp_register_plistener and cp_unregister_plistener) and dynamic symbol functions must not be called from within a plug-in listener invocation. Listener functions are registered using cp_register_plistener.

Parameters:
plugin_id the plug-in identifier
old_state the old plug-in state
new_state the new plug-in state
user_data the user data pointer supplied at listener registration

typedef void(*) cp_logger_func_t(cp_log_severity_t severity, const char *msg, const char *apid, void *user_data)

A logger function called to log selected plug-in framework messages.

The messages may be localized. Plug-in framework API functions must not be called from within a logger function invocation. In a multi-threaded environment logger function invocations are serialized by the framework. Logger functions are registered using cp_register_logger.

Parameters:
severity the severity of the message
msg the message to be logged, possibly localized
apid the identifier of the activating plug-in or NULL for the main program
user_data the user data pointer given when the logger was registered

typedef void(*) cp_fatal_error_func_t(const char *msg)

A fatal error handler for handling unrecoverable errors.

If the error handler returns then the framework aborts the program. Plug-in framework API functions must not be called from within a fatal error handler invocation. The fatal error handler function is set using cp_set_fatal_error_handler.

Parameters:
msg the possibly localized error message

typedef int(*) cp_run_func_t(void *plugin_data)

A run function registered by a plug-in to perform work.

The run function should perform a finite chunk of work and it should return a non-zero value if there is more work to be done. Run functions are registered using cp_run_function and the usage is discussed in more detail in the serial execution section.

Parameters:
plugin_data the plug-in instance data pointer
Returns:
non-zero if there is more work to be done or zero if finished

[Functions]

Detailed Description

These functions are used for framework initialization.

They are intended to be used by the main program. These functions are not thread safe.


Functions

void cp_set_fatal_error_handler (cp_fatal_error_func_t error_handler)
 Sets the fatal error handler called on non-recoverable errors.
cp_status_t cp_init (void)
 Initializes the plug-in framework.
void cp_destroy (void)
 Destroys the plug-in framework and releases the resources used by it.

Function Documentation

void cp_set_fatal_error_handler ( cp_fatal_error_func_t  error_handler  ) 

Sets the fatal error handler called on non-recoverable errors.

The default error handler prints the error message out to standard error and aborts the program. If the user specified error handler returns then the framework will abort the program. Setting NULL error handler will restore the default handler. This function is not thread-safe and it should be called before initializing the framework to catch all fatal errors.

Parameters:
error_handler the fatal error handler

cp_status_t cp_init ( void   ) 

Initializes the plug-in framework.

This function must be called by the main program before calling any other plug-in framework functions except framework information functions and cp_set_fatal_error_handler. This function may be called several times but it is not thread-safe. Library resources should be released by calling cp_destroy when the framework is not needed anymore.

Additionally, to enable localization support, the main program should set the current locale using

 setlocale(LC_ALL, "")
before calling this function.

Returns:
CP_OK (zero) on success or error code on failure

void cp_destroy ( void   ) 

Destroys the plug-in framework and releases the resources used by it.

The plug-in framework is only destroyed after this function has been called as many times as cp_init. This function is not thread-safe. Plug-in framework functions other than cp_init, cp_get_framework_info and cp_set_fatal_error_handler must not be called after the plug-in framework has been destroyed. All contexts are destroyed and all data references returned by the framework become invalid.

Plug-in context initialization
[Functions]

Detailed Description

These functions are used to manage plug-in contexts from the main program perspective.

They are not intended to be used by a plug-in runtime. From the main program perspective a plug-in context is a container for installed plug-ins. There can be several plug-in context instances if there are several independent sets of plug-ins. However, different plug-in contexts are not very isolated from each other in practice because the global symbols exported by a plug-in runtime in one context are visible to all plug-ins in all context instances.


Functions

cp_context_t * cp_create_context (cp_status_t *status)
 Creates a new plug-in context which can be used as a container for plug-ins.
void cp_destroy_context (cp_context_t *ctx)
 Destroys the specified plug-in context and releases the associated resources.
cp_status_t cp_register_pcollection (cp_context_t *ctx, const char *dir)
 Registers a plug-in collection with a plug-in context.
void cp_unregister_pcollection (cp_context_t *ctx, const char *dir)
 Unregisters a previously registered plug-in collection from a plug-in context.
void cp_unregister_pcollections (cp_context_t *ctx)
 Unregisters all plug-in collections from a plug-in context.

Function Documentation

cp_context_t* cp_create_context ( cp_status_t *  status  ) 

Creates a new plug-in context which can be used as a container for plug-ins.

Plug-ins are loaded and installed into a specific context. The main program may have more than one plug-in context but the plug-ins that interact with each other should be placed in the same context. The resources associated with the context are released by calling cp_destroy_context when the context is not needed anymore. Remaining contexts are automatically destroyed when the plug-in framework is destroyed.

Parameters:
status pointer to the location where status code is to be stored, or NULL
Returns:
the newly created plugin context, or NULL on failure

void cp_destroy_context ( cp_context_t *  ctx  ) 

Destroys the specified plug-in context and releases the associated resources.

Stops and uninstalls all plug-ins in the context. The context must not be accessed after calling this function.

Parameters:
ctx the context to be destroyed

cp_status_t cp_register_pcollection ( cp_context_t *  ctx,
const char *  dir 
)

Registers a plug-in collection with a plug-in context.

A plug-in collection is a directory that has plug-ins as its immediate subdirectories. The plug-in context will scan the directory when cp_scan_plugins is called. Returns CP_OK if the directory has already been registered. A plug-in collection can be unregistered using cp_unregister_pcollection or cp_unregister_pcollections.

Parameters:
ctx the plug-in context
dir the directory
Returns:
CP_OK (zero) on success or CP_ERR_RESOURCE if insufficient memory

void cp_unregister_pcollection ( cp_context_t *  ctx,
const char *  dir 
)

Unregisters a previously registered plug-in collection from a plug-in context.

Plug-ins already loaded from the collection are not affected. Does nothing if the directory has not been registered. Plug-in collections can be registered using cp_register_pcollection.

Parameters:
ctx the plug-in context
dir the previously registered directory

void cp_unregister_pcollections ( cp_context_t *  ctx  ) 

Unregisters all plug-in collections from a plug-in context.

Plug-ins already loaded are not affected. Plug-in collections can be registered using cp_register_pcollection.

Parameters:
ctx the plug-in context

Function Documentation

cp_plugin_info_t* cp_load_plugin_descriptor ( cp_context_t *  ctx,
const char *  path,
cp_status_t *  status 
)

Loads a plug-in descriptor from the specified plug-in installation path and returns information about the plug-in.

The plug-in descriptor is validated during loading. Possible loading errors are reported via the specified plug-in context. The plug-in is not installed to the context. If operation fails or the descriptor is invalid then NULL is returned. The caller must release the returned information by calling cp_release_plugin_info when it does not need the information anymore, typically after installing the plug-in. The returned plug-in information must not be modified.

Parameters:
ctx the plug-in context
path the installation path of the plug-in
status a pointer to the location where status code is to be stored, or NULL
Returns:
pointer to the information structure or NULL if error occurs

cp_status_t cp_install_plugin ( cp_context_t *  ctx,
cp_plugin_info_t *  pi 
)

Installs the plug-in described by the specified plug-in information structure to the specified plug-in context.

The plug-in information must have been loaded using cp_load_plugin_descriptor with the same plug-in context. The installation fails on CP_ERR_CONFLICT if the context already has an installed plug-in with the same plug-in identifier. Installation also fails if the plug-in tries to install an extension point which conflicts with an already installed extension point. The plug-in information must not be modified but it is safe to call cp_release_plugin_info after the plug-in has been installed.

Parameters:
ctx the plug-in context
pi plug-in information structure
Returns:
CP_OK (zero) on success or an error code on failure

cp_status_t cp_scan_plugins ( cp_context_t *  ctx,
int  flags 
)

Scans for plug-ins in the registered plug-in directories, installing new plug-ins and upgrading installed plug-ins.

This function can be used to initially load the plug-ins and to later rescan for new plug-ins.

When several versions of the same plug-in is available the most recent version will be installed. The upgrade behavior depends on the specified flags. If CP_SP_UPGRADE is set then upgrades to installed plug-ins are allowed. The old version is unloaded and the new version installed instead. If CP_SP_STOP_ALL_ON_UPGRADE is set then all active plug-ins are stopped if any plug-ins are to be upgraded. If CP_SP_STOP_ALL_ON_INSTALL is set then all active plug-ins are stopped if any plug-ins are to be installed or upgraded. Finally, if CP_SP_RESTART_ACTIVE is set all currently active plug-ins will be restarted after the changes (if they were stopped).

When removing plug-in files from the plug-in directories, the plug-ins to be removed must be first unloaded. Therefore this function does not check for removed plug-ins.

Parameters:
ctx the plug-in context
flags the bitmask of flags
Returns:
CP_OK (zero) on success or an error code on failure

cp_status_t cp_start_plugin ( cp_context_t *  ctx,
const char *  id 
)

Starts a plug-in.

Also starts any imported plug-ins. If the plug-in is already starting then this function blocks until the plug-in has started or failed to start. If the plug-in is already active then this function returns immediately. If the plug-in is stopping then this function blocks until the plug-in has stopped and then starts the plug-in.

Parameters:
ctx the plug-in context
id identifier of the plug-in to be started
Returns:
CP_OK (zero) on success or an error code on failure

cp_status_t cp_stop_plugin ( cp_context_t *  ctx,
const char *  id 
)

Stops a plug-in.

First stops any dependent plug-ins that are currently active. Then stops the specified plug-in. If the plug-in is already stopping then this function blocks until the plug-in has stopped. If the plug-in is already stopped then this function returns immediately. If the plug-in is starting then this function blocks until the plug-in has started (or failed to start) and then stops the plug-in.

Parameters:
ctx the plug-in context
id identifier of the plug-in to be stopped
Returns:
CP_OK (zero) on success or CP_ERR_UNKNOWN if unknown plug-in

void cp_stop_plugins ( cp_context_t *  ctx  ) 

Stops all active plug-ins.

Parameters:
ctx the plug-in context

cp_status_t cp_uninstall_plugin ( cp_context_t *  ctx,
const char *  id 
)

Uninstalls the specified plug-in.

The plug-in is first stopped if it is active. Then uninstalls the plug-in and any dependent plug-ins.

Parameters:
ctx the plug-in context
id identifier of the plug-in to be unloaded
Returns:
CP_OK (zero) on success or CP_ERR_UNKNOWN if unknown plug-in

void cp_uninstall_plugins ( cp_context_t *  ctx  ) 

Uninstalls all plug-ins.

All plug-ins are first stopped and then uninstalled.

Parameters:
ctx the plug-in context

cp_plugin_info_t* cp_get_plugin_info ( cp_context_t *  ctx,
const char *  id,
cp_status_t *  status 
)

Returns static information about the specified plug-in.

The returned information must not be modified and the caller must release the information by calling cp_release_info when the information is not needed anymore. When a plug-in runtime calls this function it may pass NULL as the identifier to get information about the plug-in itself.

Parameters:
ctx the plug-in context
id identifier of the plug-in to be examined or NULL for self
status a pointer to the location where status code is to be stored, or NULL
Returns:
pointer to the information structure or NULL on failure

cp_status_t *  status,
int *  num 
)

Returns static information about the installed plug-ins.

The returned information must not be modified and the caller must release the information by calling cp_release_info when the information is not needed anymore.

Parameters:
ctx the plug-in context
status a pointer to the location where status code is to be stored, or NULL
num a pointer to the location where the number of returned plug-ins is stored, or NULL
Returns:
pointer to a NULL-terminated list of pointers to plug-in information or NULL on failure

cp_ext_point_t** cp_get_ext_points_info ( cp_context_t *  ctx,
cp_status_t *  status,
int *  num 
)

Returns static information about the currently installed extension points.

The returned information must not be modified and the caller must release the information by calling cp_release_info when the information is not needed anymore.

Parameters:

the current state of the plug-in

cp_status_t cp_register_plistener ( cp_context_t *  ctx,
cp_plugin_listener_func_t  listener,
void *  user_data 
)

Registers a plug-in listener with a plug-in context.

The listener is called synchronously immediately after a plug-in state change. There can be several listeners registered with the same context. A plug-in listener can be unregistered using cp_unregister_plistener and it is automatically unregistered when the registering plug-in is stopped or when the context is destroyed.

Parameters:
ctx the plug-in context
listener the plug-in listener to be added

listener the plug-in listener to be removed

cp_cfg_element_t* cp_lookup_cfg_element ( cp_cfg_element_t *  base,
const char *  path 
)

Traverses a configuration element tree and returns the specified element.

The target element is specified by a base element and a relative path from the base element to the target element. The path includes element names separated by slash '/'. Two dots ".." can be used to designate a parent element. Returns NULL if the specified element does not exist. If there are several subelements with the same name, this function chooses the first one when traversing the tree.

Parameters:
base the base configuration element
path the path to the target element
Returns:
the target element or NULL if nonexisting

char* cp_lookup_cfg_value ( cp_cfg_element_t *  base,

Plug-in execution
[Functions]

Detailed Description

These functions support a plug-in controlled execution model.

Started plug-ins can use cp_run_function to register a run function which is called when the main program calls cp_run_plugins or cp_run_plugins_step. A run function should do a finite chunk of work and then return telling whether there is more work to be done. A run function is automatically unregistered when the plug-in is stopped. Run functions make it possible for plug-ins to control the flow of execution or they can be used as a coarse way of task switching if there is no multi-threading support.

The C-Pluff distribution includes a generic main program, cpluff-loader, which only acts as a plug-in loader. It loads and starts up the specified plug-ins, passing any additional startup arguments to them and then just calls run functions of the plug-ins. This makes it is possible to put all the application specific logic in plug-ins. Application does not necessarily need a main program of its own.

It is also safe, from framework perspective, to call these functions from multiple threads. Run functions may then be executed in parallel threads.


Functions

cp_status_t cp_run_function (cp_context_t *ctx, cp_run_func_t runfunc)
 Registers a new run function.
void cp_run_plugins (cp_context_t *ctx)
 Runs the started plug-ins as long as there is something to run.
int cp_run_plugins_step (cp_context_t *ctx)
 Runs one registered run function.
void cp_set_context_args (cp_context_t *ctx, char **argv)
 Sets startup arguments for the specified plug-in context.
char ** cp_get_context_args (cp_context_t *ctx, int *argc)
 Returns the startup arguments associated with the specified plug-in context.

Function Documentation

cp_status_t cp_run_function ( cp_context_t *  ctx,
cp_run_func_t  runfunc 
)

Registers a new run function.

The plug-in instance data pointer is given to the run function as a parameter. The run function must return zero if it has finished its work or non-zero if it should be called again later. The run function is unregistered when it returns zero. Plug-in framework functions stopping the registering plug-in must not be called from within a run function. This function does nothing if the specified run function is already registered for the calling plug-in instance.

Parameters:
ctx the plug-in context of the registering plug-in
runfunc the run function to be registered
Returns:
CP_OK (zero) on success or an error code on failure

void cp_run_plugins ( cp_context_t *  ctx  ) 

Runs the started plug-ins as long as there is something to run.

This function calls repeatedly run functions registered by started plug-ins until there are no more active run functions. This function is normally called by a thin main proram, a loader, which loads plug-ins, starts some plug-ins and then passes control over to the started plug-ins.

Parameters:
ctx the plug-in context containing the plug-ins

int cp_run_plugins_step ( cp_context_t *  ctx  ) 

Runs one registered run function.

This function calls one active run function registered by a started plug-in. When the run function returns this function also returns and passes control back to the main program. The return value can be used to determine whether there are any active run functions left. This function does nothing if there are no active registered run functions.

Parameters:
ctx the plug-in context containing the plug-ins
Returns:
whether there are active run functions waiting to be run

void cp_set_context_args ( cp_context_t *  ctx,
char **  argv 
)

Sets startup arguments for the specified plug-in context.

Like for usual C main functions, the first argument is expected to be the name of the program being executed or an empty string and the argument array should be terminated by NULL entry. If the main program is about to pass startup arguments to plug-ins it should call this function before starting any plug-ins in the context. The arguments are not copied and the caller is responsible for keeping the argument data available once the arguments have been set until the context is destroyed. Plug-ins can access the startup arguments using cp_get_context_args.

Parameters:
ctx the plug-in context
argv a NULL-terminated array of arguments

char** cp_get_context_args ( cp_context_t *  ctx,
int *  argc 
)

Returns the startup arguments associated with the specified plug-in context.

This function is intended to be used by a plug-in runtime. Startup arguments are set by the main program using cp_set_context_args. The returned argument count is zero and the array pointer is NULL if no arguments have been set.

Parameters:
ctx the plug-in context
argc a pointer to a location where the number of startup arguments is stored, or NULL for none
Returns:
an argument array terminated by NULL or NULL if not set

Dynamic symbols
[Functions]

Detailed Description

These functions can be used to dynamically access symbols exported by the plug-ins.

They are intended to be used by a plug-in runtime or by the main program.


Functions

cp_status_t cp_define_symbol (cp_context_t *ctx, const char *name, void *ptr)
 Defines a context specific symbol.
void * cp_resolve_symbol (cp_context_t *ctx, const char *id, const char *name, cp_status_t *status)
 Resolves a symbol provided by the specified plug-in.
void cp_release_symbol (cp_context_t *ctx, const void *ptr)
 Releases a previously obtained symbol.

Function Documentation

cp_status_t cp_define_symbol ( cp_context_t *  ctx,
const char *  name,
void *  ptr 
)

Defines a context specific symbol.

If a plug-in has symbols which have a plug-in instance specific value then the plug-in should define those symbols when it is started. The defined symbols are cleared automatically when the plug-in instance is stopped. Symbols can not be redefined.

Parameters:
ctx the plug-in context
name the name of the symbol
ptr pointer value for the symbol
Returns:
CP_OK (zero) on success or a status code on failure

void* cp_resolve_symbol ( cp_context_t *  ctx,
const char *  id,
const char *  name,
cp_status_t *  status 
)

Resolves a symbol provided by the specified plug-in.

The plug-in is started automatically if it is not already active. The symbol may be context specific or global. The framework first looks for a context specific symbol and then falls back to resolving a global symbol exported by the plug-in runtime library. The symbol can be released using cp_release_symbol when it is not needed anymore. Pointers obtained from this function must not be passed on to other plug-ins or the main program.

When a plug-in runtime calls this function the plug-in framework creates a dynamic dependency from the symbol using plug-in to the symbol defining plug-in. The symbol using plug-in is stopped automatically if the symbol defining plug-in is about to be stopped. If the symbol using plug-in does not explicitly release the symbol then it is automatically released after a call to the stop function. It is not safe to refer to a dynamically resolved symbol in the stop function except to release it using cp_release_symbol.

When the main program calls this function it is the responsibility of the main program to always release the symbol before the symbol defining plug-in is stopped. It is a fatal error if the symbol is not released before the symbol defining plug-in is stopped.

Parameters:
ctx the plug-in context
id the identifier of the symbol defining plug-in
name the name of the symbol
status a pointer to the location where the status code is to be stored, or NULL
Returns:
the pointer associated with the symbol or NULL on failure

void cp_release_symbol ( cp_context_t *  ctx,
const void *  ptr 
)

Releases a previously obtained symbol.

The pointer must not be used after the symbol has been released. The symbol is released only after as many calls to this function as there have been for cp_resolve_symbol for the same plug-in and symbol.

Parameters:
ctx the plug-in context
ptr the pointer associated with the symbol

Field Documentation

cp_plugin_info_t* plugin

A pointer to plug-in information containing this extension.

This reverse pointer is provided to make it easy to get information about the plug-in which is hosting a particular extension.

char* ext_point_id

The unique identifier of the extension point this extension is attached to.

This corresponds to the point attribute of an extension element in a plug-in descriptor.

char* local_id

An optional local identifier uniquely identifying the extension within the host plug-in.

NULL if not available. This corresponds to the id attribute of an extension element in a plug-in descriptor.

char* identifier

An optional unique identifier of the extension.

NULL if not available. This is automatically constructed by concatenating the identifier of the host plug-in and the local identifier of the extension.

char* name

An optional extension name.

NULL if not available. The extension name is intended for display purposes only and the value can be localized. This corresponds to the name attribute of an extension element in a plug-in descriptor.

cp_cfg_element_t* configuration

Extension configuration starting with the extension element.

This includes extension configuration information as a tree of configuration elements. These correspond to the extension element and its contents in a plug-in descriptor.

cp_plugin_import_t Struct Reference
[Data structures]

Detailed Description

Information about plug-in import.

Plug-in import structures are contained in cp_plugin_info_t::imports.


Data Fields

char * plugin_id
 The identifier of the imported plug-in.
char * version
 An optional version requirement.
int optional
 Is this import optional.

Field Documentation

char* plugin_id

The identifier of the imported plug-in.

This corresponds to the plugin attribute of the import element in a plug-in descriptor.

char* version

An optional version requirement.

NULL if no version requirement. This is the version of the imported plug-in the importing plug-in was compiled against. Any version of the imported plug-in that is backwards compatible with this version fulfills the requirement. This corresponds to the if-version attribute of the import element in a plug-in descriptor.

int optional

Is this import optional.

1 for optional and 0 for mandatory import. An optional import causes the imported plug-in to be started if it is available but does not stop the importing plug-in from starting if the imported plug-in is not available. If the imported plug-in is available but the API version conflicts with the API version requirement then the importing plug-in fails to start. This corresponds to the optional attribute of the import element in a plug-in descriptor.

Field Documentation

char* identifier

The obligatory unique identifier of the plugin.

A recommended way to generate identifiers is to use domain name service (DNS) prefixes (for example, org.cpluff.ExamplePlugin) to avoid naming conflicts. This corresponds to the id attribute of the plugin element in a plug-in descriptor.

char* name

An optional plug-in name.

NULL if not available. The plug-in name is intended only for display purposes and the value can be localized. This corresponds to the name attribute of the plugin element in a plug-in descriptor.

char* version

An optional release version string.

NULL if not available. This corresponds to the version attribute of the plugin element in a plug-in descriptor.

char* provider_name

An optional provider name.

NULL if not available. This is the name of the author or the organization providing the plug-in. The provider name is intended only for display purposes and the value can be localized. This corresponds to the provider-name attribute of the plugin element in a plug-in descriptor.

char* plugin_path

Path of the plugin directory or NULL if not known.

This is the (absolute or relative) path to the plug-in directory containing plug-in data and the plug-in runtime library. The value corresponds to the path specified to cp_load_plugin_descriptor when loading the plug-in.

char* abi_bw_compatibility

Optional ABI compatibility information.

NULL if not available. This is the earliest version of the plug-in interface the current interface is backwards compatible with when it comes to the application binary interface (ABI) of the plug-in. That is, plug-in clients compiled against any plug-in interface version from abi_bw_compatibility to version (inclusive) can use the current version of the plug-in binary. This describes binary or runtime compatibility. The value corresponds to the abi-compatibility attribute of the backwards-compatibility element in a plug-in descriptor.

char* api_bw_compatibility

Optional API compatibility information.

NULL if not available. This is the earliest version of the plug-in interface the current interface is backwards compatible with when it comes to the application programming interface (API) of the plug-in. That is, plug-in clients written for any plug-in interface version from api_bw_compatibility to version (inclusive) can be compiled against the current version of the plug-in API. This describes source or build time compatibility. The value corresponds to the api-compatibility attribute of the backwards-compatibility element in a plug-in descriptor.

char* req_cpluff_version

Optional C-Pluff version requirement.

NULL if not available. This is the version of the C-Pluff implementation the plug-in was compiled against. It is used to determine the compatibility of the plug-in runtime and the linked in C-Pluff implementation. Any C-Pluff version that is backwards compatible on binary level with the specified version fulfills the requirement.

unsigned int num_imports

Number of import entries in the imports array.

cp_plugin_import_t* imports

An array of num_imports import entries.

These correspond to import elements in a plug-in descriptor.

char* runtime_lib_name

The base name of the plug-in runtime library, or NULL if none.

A platform specific prefix (for example, "lib") and an extension (for example, ".dll" or ".so") may be added to the base name. This corresponds to the library attribute of the runtime element in a plug-in descriptor.

char* runtime_funcs_symbol

The symbol pointing to the plug-in runtime function information or NULL if none.

The symbol with this name should point to an instance of cp_plugin_runtime_t structure. This corresponds to the funcs attribute of the runtime element in a plug-in descriptor.

unsigned int num_ext_points

Number of extension points in ext_points array.

cp_ext_point_t* ext_points

An array of num_ext_points extension points provided by this plug-in.

These correspond to extension-point elements in a plug-in descriptor.

unsigned int num_extensions

Number of extensions in extensions array.

cp_extension_t* extensions

An array of num_extensions extensions provided by this plug-in.

These correspond to extension elements in a plug-in descriptor.

cp_plugin_runtime_t Struct Reference
[Data structures]

Detailed Description

Container for plug-in runtime information.

A plug-in runtime defines a static instance of this structure to pass information to the plug-in framework. The plug-in framework then uses the information to create and control plug-in instances. The symbol pointing to the runtime information instance is named by the funcs attribute of the runtime element in a plug-in descriptor.

The following graph displays how these functions are used to control the state of the plug-in instance.

Data Fields

void *(* create )(cp_context_t *ctx)
 An initialization function called to create a new plug-in runtime instance.
int(* start )(void *data)
 A start function called to start a plug-in instance.
void(* stop )(void *data)
 A stop function called to stop a plugin instance.
void(* destroy )(void *data)
 A destroy function called to destroy a plug-in instance.

Field Documentation

void*(* create)(cp_context_t *ctx)

An initialization function called to create a new plug-in runtime instance.

The initialization function initializes and returns an opaque plug-in instance data pointer which is then passed on to other control functions. This data pointer should be used to access plug-in instance specific data. For example, the context reference must be stored as part of plug-in instance data if the plug-in runtime needs it. On failure, the function must return NULL.

C-pluff API functions must not be called from within a create function invocation and symbols from imported plug-ins must not be used because they may not available yet.

Parameters:
ctx the plug-in context of the new plug-in instance
Returns:
an opaque pointer to plug-in instance data or NULL on failure

int(* start)(void *data)

A start function called to start a plug-in instance.

The start function must return zero (CP_OK) on success and non-zero on failure. If the start fails then the stop function (if any) is called to clean up plug-in state. Library initialization, plug-in context management and plug-in management functions must not be called from within a start function invocation. The start function pointer can be NULL if the plug-in runtime does not have a start function.

The start function implementation should set up plug-in and return promptly. If there is further work to be done then a plug-in can start a thread or register a run function using cp_run_function. Symbols from imported plug-ins are guaranteed to be available for the start function.

Parameters:
data an opaque pointer to plug-in instance data
Returns:
non-zero on success, or zero on failure

void(* stop)(void *data)

A stop function called to stop a plugin instance.

This function must cease all plug-in runtime activities. Library initialization, plug-in context management, plug-in management functions, cp_run_function and cp_resolve_symbol must not be called from within a stop function invocation. The stop function pointer can be NULL if the plug-in runtime does not have a stop function. It is guaranteed that no run functions registered by the plug-in are called simultaneously or after the call to the stop function.

The stop function should release any external resources hold by the plug-in. Dynamically resolved symbols are automatically released and dynamically defined symbols and registered run functions are automatically unregistered after the call to stop function. Resolved external symbols are still available for the stop function and symbols provided by the plug-in should remain available after the call to stop function (although functionality might be limited). Final cleanup can be safely done in the destroy function.

Parameters:
data an opaque pointer to plug-in instance data

void(* destroy)(void *data)

A destroy function called to destroy a plug-in instance.

This function should release any plug-in instance data. The plug-in is stopped before this function is called. C-Pluff API functions must not be called from within a destroy function invocation and symbols from imported plug-ins must not be used because they may not be available anymore. Correspondingly, it is guaranteed that the symbols provided by the plug-in are not used by other plug-ins when destroy function has been called.

Parameters:
data an opaque pointer to plug-in instance data

API: Graph Legend

Graph Legend

This page explains how to interpret the graphs that are generated by doxygen.

Consider the following example: 

/*! Invisible class because of truncation */
class Invisible { };

/*! Truncated class, inheritance relation is hidden */
class Truncated : public Invisible { };

/* Class not documented with doxygen comments */
class Undocumented { };

/*! Class that is inherited using public inheritance */
class PublicBase : public Truncated { };

/*! A template class */
template<class T> class Templ { };

/*! Class that is inherited using protected inheritance */
class ProtectedBase { };

/*! Class that is inherited using private inheritance */
class PrivateBase { };

/*! Class that is used by the Inherited class */
class Used { };

/*! Super class that inherits a number of other classes */
class Inherited : public PublicBase,
                  protected ProtectedBase,
                  private PrivateBase,
                  public Undocumented
                  public Templ<int>
{
  private:
    Used *m_usedClass;
};
If the MAX_DOT_GRAPH_HEIGHT tag in the configuration file is set to 240 this will result in the following graph:

graph_legend.png

The boxes in the above graph have the following meaning:

  • A filled black box represents the struct or class for which the graph is generated.
  • A box with a black border denotes a documented struct or class.
  • A box with a grey border denotes an undocumented struct or class.
  • A box with a red border denotes a documented struct or class forwhich not all inheritance/containment relations are shown. A graph is truncated if it does not fit within the specified boundaries.
The arrows have the following meaning:
  • A dark blue arrow is used to visualize a public inheritance relation between two classes.
  • A dark green arrow is used for protected inheritance.
  • A dark red arrow is used for private inheritance.
  • A purple dashed arrow is used if a class is contained or used by another class. The arrow is labeled with the variable(s) through which the pointed class or struct is accessible.
  • A yellow dashed arrow denotes a relation between a template instance and the template class it was instantiated from. The arrow is labeled with the template parameters of the instance.

C-Pluff, a plug-in framework for C

Overview

C-Pluff is a plug-in framework for C programs. It has been strongly inspired by the Java plug-in framework in Eclipse. C-Pluff focuses on providing core services for plug-in interaction and plug-in management. It aims to be platform neutral and supports dynamic changes to plug-in configuration without stopping the whole application or framework. It does not yet provide special facilities for distribution such as signed plug-in packages or remote plug-in repositories but it is possible to build such features on top of the current framework.

The current C-Pluff implementation and documentation is very much work in progress so it should be considered early alpha stage software. I will be updating the documentation and source distribution on this site as I proceed with documentation and implementation. If you are interested in C-Pluff, take a look at reference documentation, join mailing lists or download it. You can also send feedback, ideas and thoughts about such platform directly to the author.

Architecture

The plug-in architecture supported by C-Pluff is presented in the following figure. There is a thin main program controlling the plug-in framework. The main program is responsible for initializing and setting up the plug-in environment. Most of the application logic is contained in plug-ins which are independent components and can be developed and distributed separately. Plug-ins integrate with each other by providing extension points and extensions. An extension point is a point into which other plug-ins can attach extensions. An extension can be just information, expressed in XML format, or the plug-in may also provide program logic as part of the plug-in runtime library. The framework provides services for accessing extensions and for managing plug-in dependencies.
