Add support for a mutex lock that consumes only one bit of storage
inside of an integer on systems that support futexes. Futex is emulated
(at a higher cost) on systems that don't have it -- but only in the
contended case.
GLib users buildable with gcc 4.4. Patch by Jakub Jelinek.

* glib/gthread.c (gettime)
* gthread-win32.c (g_gettime_win32_impl):
GetSystemTimeAsFileTime() returns 100s of nanoseconds since 1601,
so offset to Unix epoch (1970) and multiply by 100 to get
nanoseconds which is what we want.

* glib/gthread.c (g_thread_init_glib): Run _g_atomic_thread_init
as the first of the full fledged initializers to allow the later
to potentially use atomic ints (which they currently do
not). (#342563, Peter Kjellerstedt)
2006-05-10 Sebastian Wilhelmi <wilhelmi@google.com>
* glib/gthread.c: Use g_atomic_pointer_set instead of old
homegrown version now that we have it. (#335198, Chris Wilson)
2006-05-09 Sebastian Wilhelmi <wilhelmi@google.com>
* glib/gthreadinit.h: Renamed to glib/gthreadprivate.h and moved
system thread identifier comparision and assignment macros from
glib/gthread.c to glib/gthreadprivate.h.
* glib/Makefile.am, glib/gatomic.c, glib/gconvert.c, glib/gmain.c,
glib/gmem.c, glib/gmessages.c, glib/grand.c, glib/gslice.c,
glib/gthread.c, glib/gutils.c, gthread/gthread-impl.c: Use
glib/gthreadprivate.h instead of glib/gthreadinit.h.
* gthread/gthread-impl.c: Use GSystemThread instead of GThread for
owner determination. This fixes#311043 and is mostly modeled
after the patch from jylefort@FreeBSD.org.
Thu Dec 1 17:32:46 2005 Tim Janik <timj@imendio.com>
* glib/gslice.[hc]: new slice allocator implementation.
* tests/slice-test.c: added random slice allocation test.
* glib/gthread.[hc]: removed newly added private thread mem API.
* glib/gthreadinit.h:
* glib/gmessages.c:
* glib/gthread.c:
* glib/gmem.c: divided glib threading initialisation into three phases,
initialisation where private keys and messaging are not available (only
needed by gmem.c), initialisation without messaging but private keys
available (gslice.c, gmessage.c), and full fledged initialisers that
server the rest of glib. initialisation functions got renamed to reflect
the limitations of their corresponding phases.
* glib/gmem.c: removed memchunk code, defer allocations to
g_slice_* instead.
* glib/gmem.[hc]: removed g_slice_* skeletons.
* glib/glib.symbols: added g_slice_* symbols.
* configure.in: check for availability of posix_memalign(3), memalign(3)
and valloc(3).
* glib/Makefile.am: added gslice.[hc].
2005-11-17 Matthias Clasen <mclasen@redhat.com>
* glib/gbacktrace.c:
* glib/gdate.c:
* glib/gthread.c: const correctness fixes, found
by Arjan van de Ven and gcc.
Tue Nov 1 16:24:20 2005 Tim Janik <timj@imendio.com>
* glib/gmem.[hc]: prepared deprecation of GMemChunk and GAllocator.
added g_slice_*() API to allocate and cache small bits of memory.
an actuall allocator implementation for g_slice_*() is still pending.
* glib/gthread.[hc]: changes from a patch by Matthias Clasen.
changed GRealThread list to use in-structure *next; fields instead
of GSList, in order for thread iteration to not depenend on g_slice_*()
indirectly.
_g_thread_mem_private_get():
_g_thread_mem_private_set(): added accessors for private memory,
needed because the ordinary GPrivate implementation relies on GArray
and GSList and therefore indirectly on working g_slice_*() allocations.
* glib/gthread.[hc]:
g_thread_foreach(): new public API function to loop over all existing threads.
* glib/gdataset.c:
* glib/gstring.c:
* glib/gcache.c:
* glib/garray.c:
* glib/gqueue.c:
* glib/gslist.c:
* glib/glist.c:
* glib/ghash.c:
* glib/gtree.c:
* glib/ghook.c:
* glib/gmain.c:
* glib/gnode.c:
removed GAllocator and free list usages and accompanying locks.
use g_slice_*() API to allocate and cache small bits of memory.
* glib/ghook.h: removed GMemChunk field from public API.
* glib/gslist.h:
* glib/glist.h: deprecate allocator API, provide _free1() for consistency.
* glib/gnode.h: deprecate allocator API.
* glib/gmain.c: reordered GPollRec fields so g_slice_free_chain() can
be used for poll rec lists.
* glib/grel.c: removed mem chunk usage, and allocated tuples via g_slice_*().
g_relation_destroy(): free all tuples from the all_tuples hash table,
this effectively maintains the life time track keeping of tuples.
g_relation_delete_tuple(): free tuples which are removed from the
all_tuples hash table. this fixes a temporary leak that was present
in the memchunk code until the destruction of the relation.
2005-03-13 Matthias Clasen <mclasen@redhat.com>
Make PLT-reduction work with gcc4, and don't include
everything in galias.h:
* glib/glib.symbols: Group symbols by header and source file.
* glib/makegalias.pl: Protect definitions by the same
preprocessor symbols used to guard the headers. Move
the alias declarations to a separate file which is
produced when calling makegalias.pl -def
* glib/Makefile.am (galiasdef.c): Add a rule to generate this
file.
* glib/*.c: Include galias.h after the other GLib headers,
include galiasdef.c at the bottom.
2004-12-07 Matthias Clasen <mclasen@redhat.com>
* glib/gutils.c (g_get_language_names): Update the returned
value after locale changes. (#160271, Christian Persch)
(_g_utils_thread_init): Initialize the language name cache
before going threaded.
* glib/gthread.c (g_thread_init_glib): Call _g_utils_thread_init().
* glib/gthreadinit.h: Add _g_utils_thread_init().
2004-10-26 Matthias Clasen <mclasen@redhat.com>
* glib/gwin32.c (g_win32_get_windows_version): Make this
function thread-safe in the GLib style.
* glib/gthreadinit.h:
* glib/gwin32.c (_g_win32_thread_init): New function to
initialize the version.
* glib/gthread.c (g_thread_init_glib): Call
_g_win32_thread_init() from here.
2004-04-10 Tor Lillqvist <tml@iki.fi>
* glib/giowin32.c
* glib/gmain.c
* glib/gstrfuncs.c
* glib/gthread.c: Decorating variable definitions with
__declspec(dllexport) causes problems on Cygwin build, and isn't
really needed for a native Win32 build with mingw or MSVC, so
remove. (#138402, Roger Leigh)
* glib/libcharset/localcharset.c: Use Win32-specific code also on
Cygwin.
* tests/uri-test.c: Don't assume that local filenames are in UTF-8
on Cygwin, either. (#138412, Roger Leigh)
2004-02-26 Sebastian Wilhelmi <seppi@seppi.de>
* configure.in, config.h.win32.in, glib/gthread.c: Removed the PID
niceness surrogate for thread priorities as requested by Tim. It
does more harm than good.
* glib/tmpl/threads.sgml: Updated to reflect removal of the PID
niceness surrogate for thread priorities.
2004-02-25 Sebastian Wilhelmi <seppi@seppi.de>
* configure.in, glib/gthread.c: For the PID thread priorities
surrogate use gettid instead of getpid. This also works with nptl
(on linux-2.6), as well as with linuxthreads (on linux-2.4).
2003-07-09 Matthias Clasen <maclas@gmx.de>
Support for one-time initialization functions. (#69668, Sebastian Wilhelmi)
* configure.in: Check whether double checked locking is safe, define g_once() in
glibconfig.h accordingly.
* glib/gthread.h: Add GOnce, GOnceStatus, G_ONCE_INIT and g_once_impl.
* glib/gthread.c (g_once_impl): Fallback implementation using a mutex if double checked
locking is unsafe.
* tests/thread-test.c: Add tests for g_once().
2003-03-14 Sebastian Wilhelmi <seppi@seppi.de>
* glib/gthread.c: Do not define function g_thread_init_glib, if
not G_THREADS_ENABLED. It's not called bu g_thread_init() then,
but calls other, in that case undefined functions.
2003-02-14 Sebastian Wilhelmi <seppi@seppi.de>
Fixes for #101264 and #99372:
* glib/gconvert.h, glib/gmain.c, glib/gmem.c, glib/gmessages.c,
glib/grand.c: Include gthreadinit.h and rename the thread
initialization functions a bit and let them start with _, so that
later we can stop exporting them.
* glib/gmem.c, glib/gmessages.c: Move the g_private_new() calls to
new functions. They have to be called after setting
g_threads_got_initialized to TRUE (see #101264).
* glib/gthread.c: Include gthreadinit.h. Renamed g_mutex_init() to
g_thread_init_glib(). Call the thread initialization functions
(which are not allowed to call g_private_new), then set
g_threads_got_initialized to TRUE, then call the other thread
initialization functions (which must not call anything but
g_private_new()).
* glib/gthreadinit.h: New private header to cleanly declare all
thread initialization functions.
* gthread/gthread-impl.c: Include gthreadinit.h. In
g_thread_init() just call g_thread_init_glib(), which in turn calls the
other functions (see #99372).
* glib/Makefile.am: Added gthreadinit.h.
Sat Dec 14 21:10:57 2002 Owen Taylor <otaylor@redhat.com>
* glib/gthread.h: Mark the contents of the strucures
in this file /*< private >*/
* glib/gthread.[ch]: Rename the 'write' field of the
structure to 'have_writer' to avoid any possible
conflict with system headers. (#90549, Morten Welinder)
