thread-utils.h: Avoid using a non-standard C construct 2009-06-05T10:13:48+00:00 Ramsay Jones ramsay@ramsay1.demon.co.uk 2009-06-04T16:12:59+00:00 3e0fb8fb56426d4645a50ce85fead9ad93ce59ba In particular, in standard C, a struct or union must have at least one member declared (ie. structs and unions cannot be empty). Some compilers allow empty structs as an extension and won't even issue a warning unless asked for it (eg, gcc requires -pedantic). Some compilers allow empty structs as an extension and will only treat it as an error if asked for strict checking (eg Digital-Mars with -A). Some compilers simply treat it as an error (eg MS Visual C/C++). Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Andreas Ericsson <ae@op5.se>

Change the use of asm/atomic.h to require -DGIT_HAS_ASM_ATOMIC 2009-01-03T05:48:40+00:00 Shawn O.

Modern kernels won't install these and some distros rm -rf the directory post kernel header install. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

Add a mutex and atomic counter abstraction and implementations 2008-12-31T21:36:55+00:00 Shawn O.

On pthreads we use pthread_mutex_t, except when we are also on glibc and can directly use its asm/atomic.h definitions. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

Add compiler/platform agnostic thread-local storage 2008-11-18T18:32:53+00:00 Andreas Ericsson ae@op5.se 2008-11-18T18:06:25+00:00 36f0f61fc8578478a9dc9b33a1a0d07cdb98a5e5 It doesn't cover all cases, but we can work on those as we go along. For now, gcc, MSVC++, Intel C/C++, IBM XL C/C++, Sun Studio C/C++ and Borland C++ Builder are the supported compilers (although we boldly assume that they all are of a recent enough version to support thread-local storage). This is intended to be used in upcoming patches that implement graceful (but TLS-dependant) error-handling in the library. As an added bonus, we also bring the online_cpus() function from git.git to detect the number of usable cpu's. Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Shawn O.
