Libgit2 is now officially include as

	#include ""

or indidividual files may be included as

Cleanup our header inclusion order to ensure pthread.h is early

2008-12-31T21:16:31+00:00

If we are using threads we need to make sure pthread.h comes
in before just about anything else.  Some platforms enable
macros that alter what other headers define.

Support building on Mac OS X by using pthread_getspecific for TLS

2008-12-31T05:56:11+00:00

The Mach-O format does not permit gcc to implement the __thread
TLS specification, so we must instead emulate it using a single
int cell allocated from memory and stored inside of the thread
specific data associated with the current pthread.

What makes this tricky is git_errno must be a valid lvalue, so
we really need to return a pointer to the caller and deference it
as part of the git_errno macro.

The GCC-specific __attribute__((constructor)) extension is used
to ensure the pthread_key_t is allocated before any Git functions
are executed in the library, as this is necessary to access our
thread specific storage.

Add an embryo of a TLS-aware error handling system

2008-11-22T20:08:00+00:00

This adds the per-thread global variable git_errno to the
system, which callers can examine to get information about
an error.

Two helper functions are added to reduce LoC-count for the
library code itself.

Also, some exceptions are made for running sparse on GIT_TLS
definitions, since it doesn't grok thread-local variables at
all.

Add compiler/platform agnostic thread-local storage

2008-11-18T18:32:53+00:00

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.
