Libraries like libxcb rely on pthread -stubs to use pthreads optionally, becoming thread-safe when linked to -libpthread, while avoiding any performance hit when running single-threaded. -libpthread-stubs supports this behavior even on platforms which do not supply -all the necessary pthread stubs. On platforms which already supply all the -necessary pthread stubs, this package ships only the pkg-config file -pthread-stubs.pc, to allow libraries to unconditionally express a dependency -on pthread-stubs and still obtain correct behavior. +Project description +------------------- + +Currently the project provides only a pkg-config [.pc] file, pthread-stubs.pc. +The latter contains the Cflags/Libs flags applicable to programs/libraries +that use only lightweight pthread API. See the next sections for the reasoning +and implementation details. + +Historically this project used to provide either: + - a .pc file, when the C runtime was providing the pthread symbols +or + - a .pc file and a library which implements weak stubs for the pthread symbols, +which are not available in the C runtime. + +Since then, the latter case was found to have a fundamental design issue. + + +Design +------ + +On platforms where the lightweight pthread symbols are provided by the runtime, +the .pc files provides empty Cflags/Libs flags. + +Currently the following platforms fit the above category: + - GNU/Linux - GCC/Clang/GLibC/Musl + - Solaris 10 and later + - Cygwin + - GNU/Hurd + - GNU/kFreeBSD + +For others, each of Cflags/Libs expands to full blown pthread. + +For example: + - FreeBSD and derivatives + - OpenBSD - uses a heavily patched copy of pthread-stubs to workaround this + - other BSD platforms ? + +Unchecked: + - MSYS/MINGW + - Darwin - GCC/Clang - should be the same as their Linux counter part + + +Many platforms have their own eccentric way of managing pthread compilation and +linkage. The ones realistically supported by pthread-stubs [and projects that +depend on it] work with '-pthread'. + +GCC supports -pthread for: +Aarch64, ARM, Darwin, IA-64, MIPS, PowerPC, SPARC, x86 +Cygwin and x86 Windows may need a trivial patch for older GCC versions. +See SVN rev 214161 and 171833/171834 respectively. + + +Clang: +Aarch64, ARM, x86 and likely others. + +SunCC/Oracle compiler: +Requires -mt -lpthread. As of Solaris 10 (oldest currently supported version) +all the pthread API lives in libc. Thus we'll _never_ get here. + + +With previous design, one could get mismatched calls to the pthreads API. +Consider the following scenario: + - Program and/or its dependencies links only against libpthread-stubs, +since it uses lightweight API. Say pthread_mutex_lock. + - At a later stage the program and/or its dependencies dlopens a library +which effectively [either directly or via any of its own dependencies] pulls a +full blown pthread. Let's call that libB. + - The libpthread-stubs weak symbols get overridden by the libB ones. + - pthread_mutex_unlock is executed (which now originates from libB) and BOOM. + +Amount and severity of issues depend on a number of factors. In either case +things go horribly wrong sooner on later. + + +The symbols +----------- + +The following list of symbols is taken from the libc provided by GLibC. + +It is deemed sufficient and reasonably accurate of what the 'lightweight' +pthread symbols are, since GLibC is one of the few (the only) implementations +which has the distinct split. + +Most/all other C runtime implementations provide all the pthread API in a +single library. + +Note that the following list is incomplete wrt libc-2.24.so and that further +symbols may be added in the future to bring the two closer.
