0df3ca8f9b Relax g_thread_init() requirements
We now allow g_thread_init(NULL) to be called after other glib calls (with
some minor limitations). This is mainly a documentation change as this
really was already possible.

We also allow g_thread_init() to be called multiple times. Only the
first call actually initializes the threading system, further calls
are ignored (but print a warning if the argument is not NULL).

2007-01-07  Matthias Clasen  <mclasen@redhat.com>

	Don't link glib against libpthread.  (#393812)
	
	* configure.in: Link gthread against librt, not glib itself.

	* glib/gthread.h:
	* glib/gthread.c: Add a new thread function, gettime.

	* glib/gtimer.c: Use gettime instead of directly working with
	the various system interfaces.

	* gthread/gthread-impl.c:
	* gthread/gthread-posix.c:
	* gthread/gthread-win32.c: Implement gettime.

	do not write to them, as we might not own them. Clean up the
	error-checking-mutex code quite a bit. (#335198, Chris Wilson)

	* 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/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.

8e91cf9eb9 Fixes for #101264 and #99372:
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.

	* glib/gthread.c: Set the normal PID surrogate priority according
	to getpid() to avoid errors for niced processes. (#86116)

	* gthread/gthread-impl.c, gthread/gthread-posix.c,
	gthread/gthread-solaris.c: Do the same for the posix/dce
	implementation. Solaris still needs to set priority of the main
	thread, because all unbound threads will schedule according to
	that value and it defaults to 0 (the minimal value).

2001-09-24  Bruno Haible  <haible@clisp.cons.org>

	* glib/gwin32.c (g_win32_getlocale): When the sublangid is
	SUBLANG_DEFAULT, return the locale of the language's main country,
	not a country-neutral locale. E.g. "en_US" instead of "en". Add
	handling of LANG_SORBIAN. Fix typo for SUBLANG_CHINESE_SIMPLIFIED
	(China == CN, CH == Switzerland). Ignore empty environment
	variable values.

2001-09-28  Tor Lillqvist  <tml@iki.fi>

	* glib/makefile.{mingw,msc}.in: Add localcharset.o. Just copy the
	source file from libcharset and compile in this directory.

	* glib/giochannel.c: Mark rest of g_set_error strings for
	translation, too.

	* glib/giowin32.c: Add some debugging output functions, call them
	when debugging.
	(create_events, g_io_win32_msg_write): Free message fetched with
	g_win32_error_message ().
	(g_io_win32_check): Indentation fixes.
	(g_io_win32_fd_read,g_io_win32_sock_read): Don't always return
	G_IO_STATUS_NORMAL. Do return G_IO_STATUS_EOF if we got 0 bytes,
	like on Unix. This helps making the test programs run
	successfully.

	* glib/gmain.c (g_poll): Return the code ifdeffed out with
	TEST_WITHOUT_THIS. Can't remember why it was ifdeffed out. Things
	seem to work as previously with the code in place. Especially
	spawn-test didn't work with the code ifdeffed out (Bug#61067).

	* glib/grand.c (g_rand_new): Don't try to use /dev/urandom unless
	on Unix.

	* glib/gspawn-win32-helper.c (WinMain): Remove Sleep(10000)
	accidentally left in.

gthread:

2001-09-28  Tor Lillqvist  <tml@iki.fi>

	* gthread-win32.c: Use an extra level of indirection for GMutex.
	It is now a pointer either to a pointer to a CRITICAL_SECTION
	struct, or to a mutex HANDLE. This is needed in case the user
	defines G_ERRORCHECK_MUTEXES. G_MUTEX_SIZE must correctly reflect
	the size of *GMutex, but this used to vary depending on whether we
	at run-time chose to use CRITICAL_SECTIONs or mutexes.
	(g_mutex_free_win32_cs_impl, g_cond_free_win32_impl): Call
	DeleteCriticalSection() when done with it.

	* gthread-impl.c (g_thread_init_with_errorcheck_mutexes): Call
	g_thread_impl_init() before accessing
	g_thread_functions_for_glib_use_default, as the
	g_thread_impl_init() function might modify it.

        * glibconfig.h.win32.in: Define G_HAVE_ISO_VARARGS for gcc, don't
        know about MSC. Define G_THREADS_IMPL_WIN32 instead of
        G_THREADS_IMPL_POSIX and define the right static mutex macros and
        types.

        * build/win32/make.mingw (CXX): Removed PTHREAD defs. Added
	-O2 -Wall to compile flags.

        * gthread/gthread-impl.c (g_thread_init): Move the thread
	implementation initialization to before assigning
  	GThreadFuncs, which now is just struct assigned and not
	memcpy'ed. Completed check for zero members of GThreadFuncs.

        * gthread/makefile.mingw: Don't link to pthread anymore.

        * gthread/gthread-win32.c: New file for native thread support for
        win32. Thanks to Hans Breuer <hans@breuer.org> to got me
        kickstarted.

	* gthread.c, gthread.h: Added g_static_mutex_free to allow using
	GStaticMutexes with limited lifetime without leaking.

	* configure.in: GStaticMutex doesn't have to provide extra space
	for debugging information for G_ERRORCHECK_MUTEXES, as then the
	non-default implementation (runtime_mutex) is used anyway.

	for -DG_ERRORCHECK_MUTEXES and not the name of the mutex.

	* gthread.c: Set the thread data before locking the mutex, because
	the locking call might use g_thread_self ().

	* gthread.h: Do only show the location of the locking/unlocking
	for -DG_ERRORCHECK_MUTEXES and not the name of the mutex. Add the

a3036a5bd2 Add a surrogate for thread priorities using PID niceness for systems with
2000-11-21  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* configure.in: Add a surrogate for thread priorities using PID
	niceness for systems with no thread priorities and different PIDs
	for threads of the same process (most notably: Linux). Define
	G_THREAD_USE_PID_SURROGATE in that case, as used by
	gthread-posix.c. Also make the system thread bigger by
	sizeof (long) to contain the thread's PID.

	* gfileutils.c: Include stdlib.h for mkstemp prototype.

	* gthread.c: Add priority range checks to the affected functions.

	* gthreadpool.c: Remove unused variable.

	* gthread-impl.c, gthread-posix.c, gthread-solaris.c: Removed
	g_thread_map_priority function in favour of the
	g_thread_priority_map array.  Initialize the array with
	PRIORITY_{...}_VALUE, if available and interpolate beetween the
	bounds if .._NORMAL_.. and .._HIGH_.. are not available.

	* gthread-posix.c: If we should use the PID niceness as a
	surrogate for thread priorities (G_THREAD_USE_PID_SURROGATE is
	defined), then disable normal priority handling and use PIDs and
	setpriority() instead. Depends on the thread to write its PID into
	the place after the thread id right after thread creation.

2000-09-29  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* configure.in, glib.h: Added errorcheck mutexes. These are
	activated through the preprocessor symbol
	G_ERRORCHECK_MUTEXES. Need to add an extra word to StaticMutex in
	order to achieve this. g_(static_)mutex_* functions instrument the
	mutex operations with mutex name and location, when compiled with
	-DG_ERRORCHECK_MUTEXES. g_thread_init activates the errorcheck
	mutexes, when compiled with -DG_ERRORCHECK_MUTEXES.

	* gthread/gthread-impl.c: Added errorcheck mutexes. New
        exported function
        g_thread_init_with_errorcheck_mutexes, which is called instead of
	g_thread_init, when compiled with -DG_ERRORCHECK_MUTEXES. New
	static functions
	g_mutex_(new|lock|trylock|unlock|free)_errorcheck_impl to
	implement errorcheck mutexes.

	* gthread/gthread-posix.impl.c, gthread/gthread-solaris-impl.c:
        Define the size of a mutex.

1999-06-17  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* configure.in, acglib.m4, acconfig.h, glib.h, gthread.c:
	Completed the thread support in GLib. Thread creation,
	prioritizing threads, yielding, joining threads as well as
	reader/writer locks and recursive mutexes are now in place. Please
	test heavily on your platform. It is so far tested on
	Linux/i386/pthreads, Solaris/Sparc/pthreads and
	Solaris/Sparc/solaristhreads.

	* gtimer.c, glib.h: Implement g_usleep (gulong microseconds) for
	thread safe sleeping. (sleep() is not MT-safe at all!)

	* gutils.c: Avoid compiler warning.

	* tests/Makefile.am, tests/thread-test.c: New program to test some
	aspects of the thread implementation.

	* gthread.c, Makefile.am: Renamed from gmutex.c to reflect the
	change of content.

	* configure.in: Purged all appearances of nspr.

	* gthread/gthread-posix.c, gthread-solaris.c: Added the native
	implementations for the GLib's extended thread support.

	* gthread/gthread-nspr.c: Removed for good. NSPR is nothing we
	would want to build upon.

	* gthread/gthread.c: Renamed to gthread-impl.c to avoid
	confusion with ../gthread.c (Formerly known as the file called
	gmutex.c)

	* gthread/testgthread.c: Removed. The new and much extended
        tests are in ../tests/thread-test.c.

	* gthread/Makefile.am: Changed to reflect the changes above.
