* gmain.c (g_main_iterate): Check for two threads
calling g_main_iterate at once.
* gmain.c: If the set of poll file descriptors changes
during a call to poll(), abort that call, and start
a new poll. My test program still segfaults
obscurely on glibc 2.0 (in read()!!!), but now it works on
glibc 2.1, so I'll blame something else for the other segfault.
Mon Mar 22 03:54:43 1999 Tim Janik <timj@gtk.org>
* glib.h:
* gmain.c: add user_data to the GSource ->check and ->prepare functions,
so it can be used to e.g. pass a GPollFd.
(g_main_poll): only add poll records with an events mask != 0 to the
fd_array. don't even bother calling poll_func() if fds=timeout=0.
added debugging printouts around poll_func() invokation that can be
enabled with #define G_MAIN_POLL_DEBUG.

* *.[ch]: inserted additional note to look for ChangeLog and
AUTHORS file for a log of modifications.
1999-02-10 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h: s/G_LOCK_DECLARE/G_LOCK_DEFINE/ throuhout glib. Added
G_LOCK_EXTERN macro to declare a lock externally.
Mon Feb 1 19:04:28 1999 Owen Taylor <otaylor@redhat.com>
* gmain.c (g_main_iterate): Release the main_loop
lock around calls to prepare() and check() so
that we are not holding the main loop lock
over user code.
Sun Jan 17 14:13:52 1999 Tim Janik <timj@gtk.org>
* glib.h: added a define G_HOOK_DEFERRED_DESTROY, to substitute a noop
GHookList.hook_destroy function.
* ghook.c (g_hook_destroy_link): don't really call hook_destroy if it
is G_HOOK_DEFERRED_DESTROY. for the case where we invoke hook->destroy()
we now clean up the hook completely afterwards, i.e. data, func and
destroy are immediately set to NULL and hook_free can't play with that
values anymore.
* gmain.c (g_source_add): set hook_destroy to G_HOOK_DEFERRED_DESTROY,
instead of using an ugly _noop() hack, this is to avoid an uneccessary
function invokation. set hook_free to g_source_destroy_func, this way
we always invoke the destroy notifiers for user_data and source_data
after execution of dispatch(). thus, g_source_destroy_func() will always
be called within the main_loop lock (this wasn't really assured
before), and can release and reaquire the look around destroy notifier
invokation.
Sun Jan 17 05:12:17 1999 Tim Janik <timj@gtk.org>
* configure.in: incremented version number to 1.1.13, bin age 0,
interface age 0.
* glib.h: added hook_destroy member to struct _GHookList.
* ghook.c (g_hook_destroy_link): if the hook_list defines a hook_destroy
function, use that to marshal hook destruction notifiers.
* gmain.c: removed g_source_free_func and added g_source_destroy_func,
which marshalls the user_data and source_data destructors of sources
outside of the main_loop lock.
removed GIdleData struct since its single member callback can be passed
as source_data directly.
added a gboolean return value to all g_source_remove* functions,
indicating whether the source could be removed, because these functions
don't issue warnings upon unseccessful removals themselves. this way at
least the caller gets a chance to warn upon failing removals.
(g_main_iterate): set in_check_or_prepare around calls to check() or
prepare().
(g_main_pending): simply return FALSE if called from within check() or
prepare().
(g_main_iteration): issue a warning if called from within check() or
prepare() and bail out with FALSE.
(g_main_run): likewise.
(g_source_remove_by_funcs_user_data): new function to remove sources by
user data and function table.
(g_idle_remove_by_data): new function to really remove idles only, since
g_source_remove_by_user_data would remove timeouts or other sources as
well.
* README.win32: More text.
* config.h.win32 glibconfig.h.win32: Update to match the
corresponding generated files on Unix.
* makefile.msc: Update with new source files, and gthread
library. Use the compiler flag -MD instead of using -D_DLL and
"/nodefaultlib:libc msvcrt.lib" in the link phase.
* glib.def: Include new functions, drop removed ones.
* glib.h: Add comments about main loop and polling on Win32. (In
general, it's only for the GIMP's use.) Add Win32 IO Channel
functions. Remove the obsoleted old IO Channel stuff (which was
in #if 0 already).
* giowin32.c: New file.
* gmain.c: Include config.h, conditionalize <sys/time.h>
inclusion. Add g_poll implementation for Win32 (only for the
GIMP's needs for now, it's hard or even impossible to be as clean
and generic as on Unix). Implement g_get_current_time on Win32. If
threads aren't supported, don't try to wake up main thread's
loop. On Win32, use a semaphore and not a pipe to wake up the main
loop.
* gmessages.c: On Win32, allocate a console window if the standard
output handle is invalid before writing to stdout, and reopen stdout
to that console window.
* giochannel.c: Conditionalize unistd.h inclusion. Some indentation
cleanup.
* gstrfuncs.c: Include <signal.h>.
* gutils.c: On Win32, also check the HOMEDRIVE and HOMEPATH
environment variables.
* gmodule-dl.c gmodule-dld.c: In
_g_module_build_path, don't add the "lib" prefix and
".so" or ".sl" suffix if already there.
* gmodule-win32.c: Likewise for the ".dll" suffix.
* gthread-posix.c: Conditionalize <sys/time.h> inclusion.
Thu Jan 7 15:14:08 1999 Owen Taylor <otaylor@redhat.com>
* gmain.c (g_source_free_func): Call the source-specific
free function when the hook is freed not when it
is destroyed; this fixes a bug where a timeout destroyed
from itself would access already freed data.
Mon Jan 4 20:58:50 1999 Tim Janik <timj@gtk.org>
* gscanner.c: eliminated extraneous "register" qualifiers in variable
declarations.
* gmain.c: #undef events and revents which may have been defined in
sys/poll.h for SVR3,4 compatibility on some AIX systems. fix been
provided by Philippe Defert <Philippe.Defert@cern.ch>.
Sat Jan 2 02:20:59 1999 Tim Janik <timj@gtk.org>
* ghook.c:
(g_hook_list_invoke):
(g_hook_list_invoke_check):
(g_hook_list_marshal_check):
(g_hook_list_marshal): avoid unneccessary extra hook referencing (the
explicit hook referencing became unneccessarry with my changes from
Mon Dec 21 21:48:29 1998).
* gmain.c (g_main_iterate): fixed reference counting leaks with
premature loop aborts.
Fri Jan 1 22:47:44 1999 Tim Janik <timj@gtk.org>
* gscanner.c (g_scanner_unexp_token): handle G_TOKEN_IDENTIFIER_NULL
as G_TOKEN_IDENTIFIER.
Wed Dec 23 04:18:11 1998 George Lebl <jirka@5z.com>
* gmain.c: (g_get_current_time) don't cast to timeval since
timeval is for some reason not always a struct of longs, weird
Mon Dec 21 21:48:29 1998 Tim Janik <timj@gtk.org>
* glib.h:
* gmain.c: there was a reference count race for hooks during invocation
loops. since all (known) hook loop implementations, do currently start
out with g_hook_first_valid() and iterate with g_hook_next_valid(),
g_hook_first_valid() will now return a referenced hook, and
g_hook_next_valid() will "eat" that, and eventually transfer it to
the next hook. <sigh> unfortunately this requires g_hook_next_valid()
to take the hook_list as additional argument.
* gmain.c (g_main_iterate): adjusted callers of g_hook_next_valid().
Mon Dec 21 03:48:04 1998 Tim Janik <timj@gtk.org>
* gmain.c (g_main_iterate): default initialize source_timeout with -1
so we have a sane timeout value if (*prpare) doesn't set it.
Sat Dec 19 16:56:02 1998 Owen Taylor <otaylor@redhat.com>
* gmain.c (g_main_poll): Allocate space for pollfd's
_after_ adding poll wake-up-pipe record.
* gmain.c (g_main_add_poll): Changed name
of internal function g_main_add_poll_unlocked()
back from the non-sensical g_main_add_unlocking_poll().
Fri Dec 18 00:03:17 1998 Tim Janik <timj@gtk.org>
* glib.h:
* gmain.c:
(g_main_is_running): new function to check whether a main loop has been
quitted.
(g_main_new): added a gboolean argument to determine whether the loop
should be considered initially running or not. however, g_main_run ()
will still reset the main loops running state to TRUE upon initial
entrance.
* gmain.c:
(g_main_iterate): documented this function's purpose in 5 steps.
for step 2), flag sources as G_SOURCE_READY even if !dispatch and
check G_SOURCE_READY prior to (*prepare), so we don't call (*prepare)
on them multiple times.
Thu Dec 17 23:43:47 1998 Tim Janik <timj@gtk.org>
* gmain.c (g_main_add_poll): reordered arguments, so GPollFD* comes
first, <sigh> (sorry Snorfle, i should have let you know in the first
place).
(g_main_dispatch): stack G_HOOK_FLAG_IN_CALL flags. call source's
destructor when destroying a source.
Wed Dec 16 22:32:13 CST 1998 Shawn T. Amundson <amundson@gtk.org>
* glib.h:
giounix.c: s/g_main_poll_add/g_main_remove_add/g
s/g_main_poll_remove/g_main_remove_poll/g
s/g_main_poll_add_unlocking/g_main_add_unlocking_poll/g
(from Tim Janik)
* gthread-posix.c: use g_free in mutex_free (from Tim Janik)
Thu Dec 17 04:10:49 1998 Tim Janik <timj@gtk.org>
* glib.h (G_LOCK_DECLARE_*): if !G_THREADS_ENABLED, eat the
trailing semicolon with a bogus function declaration, instead
of with a bogus variable declarations, so we avoid unused
variable warnings.
1998-12-16 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* docs/glib-config.1: Updated to reflect the existence of gthread.
* gmain.c (g_main_poll_add_unlocking): Changed
g_main_poll_add_unlocked to g_main_poll_add_unlocking to match
semantic, (indeed, main_loop must be locked, when calling this
function). Removed the unlocking from the end of that function, as
that is not right. Made a 'HOLDS' comment above the function.
Wed Dec 16 03:16:58 1998 Tim Janik <timj@gtk.org>
* configure.in: version bump to 1.1.8, binary age 0, interface age 0.
* glib.h: changed g_lock() to G_LOCK(), g_unlock() to G_UNLOCK() and
g_trylock() to G_TRYLOCK(), since these are macros that expand to
nothing with --disable-threads.
changed G_LOCK_DEFINE() to G_LOCK_DECLARE() and introduced
G_LOCK_DECLARE_STATIC() to achive the results of static G_LOCK_DECLARE().
changed semantics of g_thread_supported to g_thread_supported() so it
can be used as a function like g_module_supported(). the actuall
definition is still a macro that expands into a variable for
performance reasons though.
various indentation and coding style cleanups.
* configure.in: added --enable-threads that defaults to yes.
* gmutex.c: changed tests g_thread_supported to g_thread_supported (),
changed variable settings of g_thread_supported
to g_threads_got_initialized.

In brief overview:
- The set of threading functions can be set
- A default implementation is provided in -lgthread
- All static data structures are locked using these
functions if g_thread_init() is called.
