Take out the half-private g_private_init() stuff and replace it with a
G_PRIVATE_INIT macro that allows specifying a GDestroyNotify.
Expose the GPrivate structure in a public header.
Add a g_private_replace() to (sort of) match the functionality of
g_static_mutex_set().
Improve the documentation.
Deprecate g_private_new().
Replace it with g_thread_create_with_stack_size() and a real function
implementation of g_thread_create().
Modify a testcase that was calling g_thread_create_full()
inappropriately (it was using the default values anyway).
Thread priorities were already documented as not working on Solaris, and
they are meaningless on Linux unless the process separately requests
realtime scheduling (and even then, it appears only to work as root).
We can safely put a NULL into the vtable for set_priority since nothing
outside of gthread.c ever calls this (and that call is gone).
We remove the macros while at the same time switching all libglib users
from g_private_new() to g_private_init(). We deal with the strange
expectations of the libglib code that g_private_* should work before the
GPrivate has been initialised with a temporary shim.
- expose the structure types for GLib internal use only
- avoid infinite recursion hazards by ensuring that GPrivate never
calls back into any other part of GLib
- substantially rework the Windows implementation so that it never
holds locks, contains no arbitrary limits and doesn't waste
100*sizeof(void*) per thread
We have to keep the macro hacks for the time being since some code
inside libglib depends on it.
Now that GMutex is exposed we can avoid the dance we did in ./configure
to allocate the correct amount of space for it within the GStaticMutex.
Remove the checks and move the definitions to gthread.h, trying very
hard to keep ABI-stable (even though we will be deprecating this soon).
Do a substantial rework of the GMutex and GCond APIs.
- remove all of the macro indirection hackery which is no longer needed
since we dropped support for switchable thread implementations
- expose the structure types and add G_MUTEX_INIT and G_COND_INIT
static initialiser macros
- add g_mutex_init() and g_mutex_clear() for use when embedding GMutex
into another structure type and do the same for GCond as well
- avoid infinite recursion hazards by ensuring that neither GCond or
GMutex ever calls back into any other part of GLib
- substantially rework the Windows implementation of GCond and GMutex
to use the SRWLock and CONDITION_VARIABLE APIs present on Windows
2008/Vista and later, emulating these APIs on XP
g_thread_gettime() is an undocumented public function pointer that
points to a function that returns the monotonic time in nanoseconds.
g_get_monotonic_time() does the same in microseconds, so it can be used
instead.
GLib had one internal user in GFileMonitor that only cared about
millisecond accuracy; it has been ported to g_get_monotonic_time().
G_THREADS_ENABLED still exists, but is always defined. It is still
possible to use libglib without threads, but gobject (and everything
above it) is now guaranteed to be using threads (as, in fact, it was
before, since it was accidentally impossible to compile with
--disable-threads).
https://bugzilla.gnome.org/show_bug.cgi?id=616754
Since gobject now initialized threads unconditionally if threads are
available it makes no sense to have each thread operation
conditionally check if threads are enables, so allow this to be avoided.

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].
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.
2004-02-29 Sebastian Wilhelmi <seppi@seppi.de>
* configure.in, glib/gatomic.c, glib/gatomic.h: Moved the
assembler functions from gatomic.h to gatomic.c, which makes for
better maintainability. Also use gint instead of gint32 to be able
to use reference counting for ABI-fixed structures with
gint/guint.
* glib/gthread.h: Adapted accordingly.
* tests/atomic-test.c: Updated to test for G_MAXINT and G_MININT.
