Finally, a new and improved IO Channel and condition watch implementation 2000-07-30 Tor Lillqvist <tml@iki.fi> 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.

Socket support rewritten. It was utterly broken, and untested in fact. We 2001-01-25 Tor Lillqvist <tml@iki.fi> * giowin32.c: Socket support rewritten. It was utterly broken, and untested in fact. We still do use a thread for each socket being watched, but instead of blocking in recv() (which of course was plain stupid for sockets being liste()ed on), we block in select(). The read method for sockets calls recv(). It is now possible for the application to call accept(), recv() or send() in the callback, just like on Unix. Tested with code kindly provided by Andrew Lanoix. Rename g_io_channel_win32_new_stream_socket() to g_io_channel_win32_new_socket() as it isn't restricted to stream sockets. * gmain.c (g_poll): Related changes in the Win32 version of g_poll(). When polling for messages, always do a PeekMessage() first. We used to miss messages if several were posted between calls to g_poll(). * giochannel.h: Improve Win32-related comments. * gutf8.c: (Win32) Include <stdio.h> for sprintf. * tests/gio-test.c: (Win32) Add tests for polling for Windows messages. * tests/makefile.mingw.in: Remove superfluous compilation command line.

Replace #ifdef HAVE_UNISTD_H checks with #ifdef G_OS_UNIX In Windows development environments that have it, <unistd.h> is mostly just a wrapper around several other native headers (in particular, <io.h>, which contains read(), close(), etc, and <process.h>, which contains getpid()). But given that some Windows dev environments don't have <unistd.h>, everything that uses those functions on Windows already needed to include the correct Windows header as well, and so there is never any point to including <unistd.h> on Windows. Also, remove some <unistd.h> includes (and a few others) that were unnecessary even on unix. https://bugzilla.gnome.org/show_bug.cgi?id=710519

Finally, a new and improved IO Channel and condition watch implementation 2000-07-30 Tor Lillqvist <tml@iki.fi> 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.

We still do use a thread for each socket being watched, but instead of blocking in recv() (which of course was plain stupid for sockets being liste()ed on), we block in select(). The read method for sockets calls recv(). It is now possible for the application to call accept(), recv() or send() in the callback, just like on Unix. Tested with code kindly provided by Andrew Lanoix.

Finally, a new and improved IO Channel and condition watch implementation 2000-07-30 Tor Lillqvist <tml@iki.fi> 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.
