1 2002-09-19 Mark Crichton <crichton@gimp.org>
3 * atomic.h: Added SPARC atomic asm code.
4 * daemon.c, handles-private.h, handles.c, wapi-private.h:
5 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
6 Solaris 9, however, the code paths don't seem to work. More testing
7 on the shared case is *really* needed.
9 2002-09-03 Dick Porter <dick@ximian.com>
12 * threads.c: Removed PosixKillThread(), because it's not in the
15 2002-08-20 Dick Porter <dick@ximian.com>
17 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
18 multiples of 4 bytes, to keep header structures aligned. Needed
19 for sparc, at least. (Patch from crichton@gimp.org)
21 * handles.c: Removed 'disable_shm' variable (we've defaulted to
22 building with shm enabled for months now)
24 2002-08-19 Dick Porter <dick@ximian.com>
26 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
27 for legacy NeXT-based systems.
29 2002-08-12 Dick Porter <dick@ximian.com>
31 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
32 from Joseph Wenninger <kde@jowenn.at>)
34 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
36 * threads.c: use fast spinlocks by default
38 2002-08-02 Dick Porter <dick@ximian.com>
40 * io.c (GetStdHandle): Add a handle reference when returning a
41 duplicate console handle. This fixes the unref_handle errors in
44 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
46 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
49 2002-08-01 Dick Porter <dick@ximian.com>
51 * threads.c: Use atomic spinlocks in TLS functions
54 * Makefile.am: Added mono-spinlock.h
56 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
58 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
59 these are needed for sendmsg() and also for struct msghdr (at
60 least on Solaris). Solaris still won't build because struct msghdr
61 doesn't have msg_flags, msg_control, or msg_controllen members.
62 (CMSG_SPACE): Define for systems that don't have it.
65 2002-07-20 Dick Porter <dick@ximian.com>
71 * handles.c: Implemented pipe handles
74 * daemon.c: Fixed bug in handle closing.
77 * daemon.c: Forked processes now close all open file descriptors.
79 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
81 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
84 2002-07-19 Martin Baulig <martin@gnome.org>
86 * threads.c (ExitThread): Call exit() if no threads has been
89 2002-07-17 Dick Porter <dick@ximian.com>
91 * daemon-messages.c: Freebsd fixes from Andreas Kohn
92 <andreas.kohn@gmx.net>
94 2002-07-15 Dick Porter <dick@ximian.com>
96 * io.c: Removed bogus console_flush() method, that was just cut
97 and pasted from file_flush when I separated the two handle types.
99 2002-07-12 Dick Porter <dick@ximian.com>
101 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
102 flags. Fixes bug 27633.
104 2002-07-12 Dick Porter <dick@ximian.com>
108 * daemon.c: Use size of sockaddr_un.sun_path from config.h
110 2002-07-12 Dick Porter <dick@ximian.com>
112 * processes.c (CreateProcess): Send stdin, stdout and stderr
113 handles if the startup info doesnt specify new ones
115 * io.c (GetStdHandle): Return the same handle when the same
116 standard handle is requested
118 * handles.c: Pass file descriptors when forking
120 * daemon.c: Use supplied file descriptors when forking a new
124 * daemon-messages.c: Pass stdin, stdout and stderr file
125 descriptors to the daemon (used when forking)
127 2002-07-11 Miguel de Icaza <miguel@ximian.com>
129 * daemon.c (_wapi_daemon_main): Use sizeof
130 (main_socket_address.sun_path) instead of hardcoded 108 value.
132 * handles.c (shared_init): Use sizeof
133 (shared_socket_address.sun_path) instead of hardcoded 108 value.
135 2002-07-10 Dennis Haney <davh@davh.dk>
139 * daemon.c: Lots of documentation, some added error checking, and
140 code readability improvements.
142 * daemon-messages.h: Add the Error request type to improve error
145 * daemon-messages.c: Do a bit more error checking on send() and
146 recv(), and log errors with a higher severity level.
148 2002-07-04 Dick Porter <dick@ximian.com>
150 * daemon.c (process_process_fork): Fix argument handling, due to
151 buggy understanding of g_strsplit() behaviour.
153 2002-07-03 Dick Porter <dick@ximian.com>
156 * threads.c: Implement OpenThread(). Define access-control values
162 * Makefile.am: Added access.h, to hold shared access-control
165 2002-07-02 Dick Porter <dick@ximian.com>
167 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
169 2002-07-02 Dick Porter <dick@ximian.com>
171 * handles.c (shared_init): Make a second attempt to contact the
172 daemon if the shared memory attach succeeds, but the connect()
173 fails. (This copes with the daemon crashing without cleaning up
179 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
180 the daemon, it's now built into the library.
182 2002-06-25 Dick Porter <dick@ximian.com>
187 * daemon.c: Process forking and handle data management
191 * processes.c: Process forking and other support functions
193 2002-06-25 Dick Porter <dick@ximian.com>
195 * versioninfo.h: PE resource decoding
197 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
198 to be told the string length
200 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
201 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
204 2002-06-12 Dick Porter <dick@ximian.com>
207 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
208 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
209 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
211 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
213 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
214 when writing to a closed socket.
216 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
218 * mono-mutex.c (mono_once): New convenience function for my
223 * critical-sections.c:
231 * atomic.c: Use mono_once() rather than pthread_once().
233 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
235 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
236 if multiple threads all try to call _wapi_handle_new() before the
237 shared data has been initialized, it is possible that we could get
238 into a condition where shared_init() is being executed and later
239 threads will pass by pthread_once() due to the fact that it has
240 already been called and so therefor will attempt to use the shared
241 data before it has been completely initialized. If we instead use
242 a standard mutex locking mechanism around shared_init(), we can
243 avoid the situation entirely. By wrapping the mutex locking in a
244 check to see if we've already initialized the data, we can even
245 avoid wasting resources by having to lock/unlock the mutex in any
246 later calls (the only time we'd have to worry about
247 locking/unlocking is the initial race to call shared_init() at
250 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
252 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
254 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
256 * daemon.c, handles.c: rename "sun" local var since it's apparently
257 a #define on Solaris.
259 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
261 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
264 2002-05-15 Dick Porter <dick@ximian.com>
266 * wait.c: Fix a deadlock in WaitForMultipleObjects
268 2002-05-14 Dick Porter <dick@ximian.com>
270 * io.c: Fix a cut&paste error, found by
271 Jaroslaw Kowalski <jarek@atm.com.pl>
273 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
277 2002-05-09 Dick Porter <dick@ximian.com>
285 * Makefile.am: Remove now-unused file wait-private.h
287 2002-05-08 Dick Porter <dick@ximian.com>
289 * shared.c: Better error messages, and report when daemon
290 connection fails rather than blocking forever. Do some more
291 shared memory sanity checking.
293 * handles.c: Better error messages when connecting to shared
294 memory and the handle daemon. Fall back to non-shared handles if
295 an error occurs. Set the default back to 'shared handles'. Fix a
296 crashing bug in scratch space allocation that mangled the block
299 2002-05-07 Miguel de Icaza <miguel@ximian.com>
301 * handles.c (shared_init): Disable SHM for now, people have too
302 many problems with this, and the diagnostics are not helping.
304 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
306 * io.c: CreateFile sets win32 last error.
308 2002-05-05 Dick Porter <dick@ximian.com>
319 * semaphore-private.h:
323 * event-private.h: Simplify the WapiHandleOps struct: take out all
324 the file-specific entries, leaving just the items that operate on
325 handles themselves. Split the close operation into shared and
326 private parts: shared close is called by the daemon.
328 * handles.c: As above, but also pass handle allocation, ref and
329 unref operations to the daemon. Populate the handle_ops array at
330 compile time, because the daemon needs to call ops on handles too.
331 Don't bother to track open handle counts any more, the daemon does
335 * thread-private.h: As above, but also make the thread data
338 * shared.c: Fork a handle daemon if the calling process created
339 the shared memory segment.
344 * Makefile.am: Build a daemon to manage handle allocation and
345 destruction without needing to lock the shared memory
347 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
349 * atomic.c: Changed to use a normal mutex rather than a spinlock
350 since a lot of platforms seem to not have them :\
352 2002-04-30 Dick Porter <dick@ximian.com>
354 * Completely rewrote the handle waiting code: removed the helper
355 thread and its attendant complexity. All handle waiting is now
356 abstracted into the WaitForSingleObject() and
357 WaitForMultipleObjects() functions.
359 * Implemented inter-process sharing of handles using sysv shared
360 memory. This makes handles even more opaque, with a handle now
361 just an index into an array.
363 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
365 * io.c: unitialized pointer in GetCurrentDirectory.
367 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
369 * threads.c: destroy the mutex at thread destruction
370 (if/when thread destruction code will be actually called).
371 When protecting a tls data pointer from the gc, use also the
372 thread id in the key.
374 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
376 * timed-thread.c: avoid race condition when setting the thread to
379 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
381 * jit.h: to more #include lines to avoid breaking compilation
382 under windows when upgrading mingw and w32api to version
385 2002-04-16 Dick Porter <dick@ximian.com>
387 * atomic.h: Explanatory comment about lack of 80386 support
389 2002-04-15 Dick Porter <dick@ximian.com>
391 * atomic.h: use xaddl for InterlockedIncrement() and
392 InterlockedDecrement(). Use cmpxchgl in a loop for
393 InterlockedExchange() and InterlockedExchangePointer().
395 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
397 * unicode.c: fix unicode_len() to not access uninitialized memory
398 (and updated to conform to mono code style).
400 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
402 * io.c: EEXISTS is ignored for directory creation.
403 * mono-mutex.h: remove silly "pragma }" that emacs users insert
404 because they use a broken editor:-)
406 2002-03-28 Dick Porter <dick@ximian.com>
412 * handles.c: Warning cleanups
414 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
416 * unicode.h, unicode.c: changed to gunichar2
417 * io.h, io.c: changed strings to gunichar2*, added
418 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
419 some fixes to FindFirstFile() and friends.

443 * atomic.c: Interlocked functions
445 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
447 * threads.c: use a gc-safe hash table to store tls pointers.
449 2002-03-22 Dick Porter <dick@ximian.com>
451 * threads.c: Fix a race condition where a thread can start and
452 exit before the handle has been properly initialised (no reason
453 why the handle couldn't be initialised beforehand, so do so)
455 Fix a ms to ns conversion magnitude thinko.
457 2002-03-21 Dick Porter <dick@ximian.com>
459 * semaphores.c: Fix a problem when waiting for one or more
460 semaphores, and another semaphore is Released (all waiting
461 semaphores assumed they were signalled)
463 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
465 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
466 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
468 2002-03-19 Dietmar Maurer <dietmar@ximian.com>

472 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
474 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
475 threads.c, io.c: added flush method to handles.
