* gmain.[hc]: Major change in API for creating sources
to handle multiple main loops (GMainContext *).
GSources are now exposed as GSource * and implemented
with structure derivation.
* giochannel.[ch]: Changed vtable for GIOChannel to correspond
to the new mainloop API, add g_io_channel_create_watch().
* gtypes.h: Move GTimeVal here.
* gthread.h: Remove gmain.h include to avoid circularity.
* giounix.c: Update for new GMain API.
* giowin32.c: Update for new GMain API. (No check for
proper compilation or working.)
* timeloop.c timeloop-basic.c: A benchmarking program for
the main loop comparing the main loop against a
hand-written (timeloop-basic.c) variant.
* tests/mainloop-test.c: New torture test of mainloop.
* docs/Changes-2.0.txt: Started. Added text about
changes to GMain.
* gmain.c (g_main_add_poll_unlocked): Initial fd->revents
to zero. (#8482, Benjamin Kahn)
2000-10-16 Tor Lillqvist <tml@iki.fi>
* giowin32.c (reader_thread): Some more debugging output.
(g_io_channel_win32_poll): Remove unused vars.
* gfileutils.c: Changes for Win32, with no unistd.h and no
S_ISLNK().
* gspawn-win32.c: Implementation of the g_spwan_* functions for
Win32. Due to the general non-Unixness of Win32, much of the
functionality that is relatively clean to implement on Unix, is
hard to do on Win32. We must use a separate helper program to
change directory, close extra file descriptors, redirect the std
ones, as needed, and only then start the child process. No child
process pid can be returned, unfortunately. Or if we used
CreateProcess directly, it probably could. (Now we use the spawnv*
functions from msvcrt.)
* glib.def: Add new entry points.
* glib.def
* giowin32.c: Remove g_io_channel_win32_wait_for_condition(),
g_io_channel_win32_poll() subsumes it.
* gbacktrace.h: G_BREAKPOINT for MSVC (on the ix86).
* gwin32.c (g_win32_getlocale): Use "sp" for
LANG_CROATIAN+SUBLANG_SERBIAN_LATIN.
* makefile.{mingw,msc}.in (glib_OBJECTS): Add new files.
Add gspawn-win32-helper.exe rule.
* tests/makefile.{mingw,msc}.in (TESTS): Add shell-test and
spawn-test.
* tests/spawn-test.c: (run_tests): On Win32, don't try to run
/bin/sh, but ipconfig (no special significance in choosing that,
just a program that outputs something to stdout).
2000-10-06 Tor Lillqvist <tml@iki.fi>
* makefile.msc.in: Revamp to be like makefile.mingw.in, make
the MSVC build actually work again.
* gmodule/makefile.msc.in
* gobject/makefile.msc.in
* gthread/makefile.msc.in: New files, like their mingw counterparts.
* gmodule/Makefile.am
* gobject/Makefile.am
* gthread/Makefile.am: Make and distribute them.
* */makefile.mingw.in: Allow override of GLib version number from
the build/win32/module.defs file.
* glib.def: Add new entry point.
Fixes from Hans Breuer:
* glib.h (struct DIR): Keep the last readdir result cached inside
the DIR struct, to enable several DIRs being open simultaneously.
* gwin32.c (g_win32_readdir): Use the above instead of static.
* giowin32.c (g_io_channel_win32_make_pollfd): Insert cast to keep
MSVC happy.
2000-08-31 Tor Lillqvist <tml@iki.fi>
* glib.h
* glib.def
* giowin32.c (g_io_channel_win32_make_pollfd): New function, to
make a GPollFD from a GIOChannel. Creates the events and starts
the reader thread if necessary.
2000-08-27 Tor Lillqvist <tml@iki.fi>
Hmm, the parameter to g_io_channel_win32_poll() should be
a GPollFD array, not GIOChannel. That way the caller can know which
channels cause the callback.
2000-08-27 Tor Lillqvist <tml@iki.fi>
* giowin32.c (g_io_channel_win32_poll): New function, otherwise
like g_io_channel_win32_wait_for_condition(), but accept several
GIOChannels.
(g_io_channel_win32_wait_for_condition): Call
g_io_channel_win32_poll().
* glib.h: Declare g_io_channel_win32_poll().
* gwin32.c (g_win32_error_message): Don't believe return value
from FormatMessage.
2000-08-12 Tor Lillqvist <tml@iki.fi>
* giowin32.c: Some indentation and spacing fixes. Add some more
logging.
(g_io_win32_add_watch): New function, with common code from
g_io_win32_fd_add_watch and g_io_win32_sock_add_watch. Don't start
more than one reader thread for a GIOChannel. We should obviously
have just one reader thread reading a file descriptor or socket.
2000-07-31 Tor Lillqvist <tml@iki.fi>
* giowin32.c (buffer_read): The code didn't compile (must
have been sleepy when committing). "return" instead of "break"
(g_io_win32_fd_add_watch): Cannot check if the file descriptor is
readable by calling ReadFile to read zero bytes. ReadFile blocks
on NT even if trying to read nothing at all. So, don't check if
file descriptor is readable; assume this function isn't called
otherwise.
2000-07-30 Tor Lillqvist <tml@iki.fi>
* giowin32.c: Compile in the debugging code all the time, but only
output debug messages if told so. Add (unadvertised) function to
turn on/off debug messages for a channel.
(buffer_read): Don't loop. It is expected behaviour to return a
short read occasionally, for instance when reading from
pipes. It's the calling code that should loop if it *knows* how
much the writer has written.
* tests/gio-test.c: Correct the program's name in the output.
(recv_message): Loop calling g_io_channel_read() (in a new
function read_all()) until we have all the bytes we want (that we
know the writer has written/will write).

Finally, a new and improved IO Channel and condition watch
implementation for Win32. Based on code provided by Craig Setera.
When watching file descriptors, for which there is no select()
like functionality on Win32 that would work on all Win32 platforms
for all types of file descriptors (including anonymous pipes), we
start a new thread that blocks while trying to read from the file
descriptor. When the read returns, a Win32 Event is signalled that
the polling routine eventually notices. Meanwhile, the data being
read is stored in a circular buffer, from where the IO channel's
read() method picks it up.
If the buffer fills up the reading thread has to wait for space
becoming available. For this another Win32 Event is used. The IO
Channel's read() method signals this when it has read some data
out of the buffer.
The separate reader thread(s), and the circular buffer(s) with
associated events mean lots of possibilities for fun parallellism
errors. But it seems to work OK, i.e. GIMP runs.
* gmain.c: Small changes to the Win32 polling function.
(g_main_win32_get_poll_func): New function. Perhaps it would be a
good idea to provide this on all platforms.
* giowin32.c: The bulk of the new implementation.
(g_io_channel_win32_wait_for_condition): New function. To be used
where on Unix one does a select() on the channel's fd, like
libgimp's gimp_extension_process(). Could be provided on all
platforms.
* glib.h: Update documentation for IO Channels on Win32. Remove
the declarations for the as of now obsolete old functions related
to IO Channels for pipes with "wakeup" messages.
* glib.def: Some new functions.
* tests/gio-test.c: New file, to test GIOChannel and main loop.
* tests/Makefile.am
* tests/makefile.mingw.in: Add it.
Wed Jul 26 12:59:31 2000 Tim Janik <timj@gtk.org>
* *.[hc]: applied patch from Andreas Persenius <ndap@swipnet.se> that
updates the license headers to the GNU Lesser General Public License,
as well as updating the copyright year to 2000.
2000-06-06 Tor Lillqvist <tml@iki.fi>
* giowin32.c (g_io_channel_win32_pipe_readable): If we are
watching the same fd several times (for different conditions, with
different callbacks), check them all. Only call the callback for
G_IO_IN from here. (This bug popped up when a watch for
G_IO_ERR|G_IO_HUP was added to gimplib.)
Wed Feb 24 00:08:42 CST 1999 Shawn T. Amundson <amundson@gtk.org>
* *.[ch]: inserted additional note to look for ChangeLog and
AUTHORS file for a log of modifications.
* 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.
