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.

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.

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.

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.

Merge in current Win32 version. Almost no Unix code touched. * 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.

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. 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.

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.

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.

Now we don't need to call TerminateThread() after all, which is a relief, as the docs have a BIG RED WARNING SIGN about using that API. Instead, when closing a fd channel that has a reader thread running, just mark it as non-running and additionally mark the fd as ripe for closing. When the reader thread hopefully eventually gets something (and EOF or some actual data), it will note that it shouldn't be running, break out of the loop, and close the fd. The socket channel closing code should probably be changed similarily, but that will have to wait until I have a test case. (g_pipe_readable_msg, g_io_channel_win32_new_pipe, g_io_channel_win32_new_pipe_with_wakeups, g_io_channel_win32_pipe_request_wakeups, g_io_channel_win32_pipe_readable): Remove these, have been obsolete for some time. * glib.def: Update.

Start reader thread with the lower-level CreateThread() instead of _beginthreadex() from the C runtime, in order to be able to use TerminateThread().

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.

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.

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.

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.

Get len using strlen() if arg is negative in the Win32 code, too. 2001-01-06 Tor Lillqvist <tml@iki.fi> * gconvert.c (g_locale_to_utf8, g_locale_from_utf8): Get len using strlen() if arg is negative in the Win32 code, too. * giowin32.c: Changes necessary to be able to run mainloop-test. We can't close the fd that our (internal) reader thread is sitting doing a blocking read() from. We must terminate the thread first. Keep track of thread handle, and close it when thread is dying. Start reader thread with the lower-level CreateThread() instead of _beginthreadex() from the C runtime, in order to be able to use TerminateThread(). Hopefuly this isn't harmful. * glib.def: Update. * tests/makefile.{mingw,msc}.in (TESTS): Add mainloop-test and unicode-encoding. * tests/mainloop-test.c: Portability: <unistd.h>, need <fcntl.h> on Win32. * tests/unicode-encoding.c (process): Add missing "line" argument to fail(). On Win32, convert UTF-16LE, as libiconv'c ivonf always converts to UTF-16BE if we ask for unspecific UTF-16. (main) Handle also '\r'.

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.

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.

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.

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.

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.

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.

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.

Now we don't need to call TerminateThread() after all, which is a relief, as the docs have a BIG RED WARNING SIGN about using that API. Instead, when closing a fd channel that has a reader thread running, just mark it as non-running and additionally mark the fd as ripe for closing. When the reader thread hopefully eventually gets something (and EOF or some actual data), it will note that it shouldn't be running, break out of the loop, and close the fd. The socket channel closing code should probably be changed similarily, but that will have to wait until I have a test case.

Now we don't need to call TerminateThread() after all, which is a relief, as the docs have a BIG RED WARNING SIGN about using that API. Instead, when closing a fd channel that has a reader thread running, just mark it as non-running and additionally mark the fd as ripe for closing. When the reader thread hopefully eventually gets something (and EOF or some actual data), it will note that it shouldn't be running, break out of the loop, and close the fd. The socket channel closing code should probably be changed similarily, but that will have to wait until I have a test case.

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.

The IO Channel's read() method signals this when it has read some data out of the buffer.

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.
