Naming conventions: include files: - _lib: library without need for a process - _service: library that needs a service process - _plugin: plugin definition - _protocol: structs used in network protocol - exceptions: * gnunet_config.h --- generated * platform.h --- first included * plibc.h --- external library * gnunet_common.h --- fundamental routines * gnunet_directories.h --- generated * gettext.h --- external library binaries: - gnunet-service-xxx: service process (has listen socket) - gnunet-daemon-xxx: daemon process (no listen socket) - gnunet-helper-xxx[-yyy]: SUID helper for module xxx - gnunet-yyy: command-line tool for end-users - libgnunet_plugin_xxx_yyy.so: plugin for API xxx - libgnunetxxx.so: library for API xxx configuration: - paths (that are substituted in all filenames) are in PATHS (have as few as possible) - globals for the daemon are in [gnunetd] (for now, have as few as possible!) - all options for a particular module (src/MODULE) are under [MODULE] - options for a plugin of a module are under [MODULE-PLUGINNAME] - options only for debugging / testing / profiling are under [TESTING], together with the options for the testing module itself exported symbols: - must start with "GNUNET_modulename_" and be defined in "modulename.c" - exceptions: those defined in gnunet_common.h private (library-internal) symbols (including structs & macros): - must NOT start with any prefix - must not be exported in a way that linkers could use them or other libraries might see them via headers; they must be either declared/defined in C source files or in headers that are in the respective directory under src/modulename/ and NEVER be declared in src/include/. testcases: - must be called "test_module-under-test_case-description.c" - "case-description" maybe omitted if there is only one test performance tests: - must be called "perf_module-under-test_case-description.c" - "case-description" maybe omitted if there is only one performance test - Must only be run if HAVE_BENCHMARKS is satisfied src/ directories: - gnunet-NAME: end-user applications (i.e., gnunet-search, gnunet-arm) - gnunet-service-NAME: service processes with accessor library (i.e., gnunet-service-arm) - libgnunetNAME: accessor library (_service.h-header) or standalone library (_lib.h-header) - gnunet-daemon-NAME: daemon process without accessor library (i.e., gnunet-daemon-hostlist) and no GNUnet management port - libgnunet_plugin_DIR_NAME: loadable plugins (i.e., libgnunet_plugin_transport_tcp) Coding style: - GNU guidelines apply - declare only one variable per line, so int i; int j; instead of int i,j; Build-system: If you have code that is likely not to compile or build rules you might want to not trigger for most developers, use "if HAVE_EXPERIMENTAL" in your Makefile.am. Then it is OK to (temporarily) add non-compiling (or known-to-not-port) code. If you want to compile all testcases but NOT run them, run configure with the --enable-test-suppression option. If you want to run all testcases, including those that take a while, run configure with the --enable-expensive-testcases option. If you want to compile and run benchmarks, run configure with the --enable-benchmarks option. If you want to obtain code coverage results, run configure with the --enable-coverage option and run the coverage.sh script in contrib/. Minimum file-sharing system (in order of dependency): gnunet-service-arm gnunet-service-transport gnunet-service-core gnunet-daemon-hostlist gnunet-daemon-topology gnunet-service-statistics gnunet-service-datastore gnunet-service-datacache gnunet-service-dht gnunet-service-fs
