3 * threads.c: use fast spinlocks by default
5 2002-08-02 Dick Porter <dick@ximian.com>
7 * io.c (GetStdHandle): Add a handle reference when returning a
8 duplicate console handle. This fixes the unref_handle errors in
11 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
13 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
16 2002-08-01 Dick Porter <dick@ximian.com>
18 * threads.c: Use atomic spinlocks in TLS functions
21 * Makefile.am: Added mono-spinlock.h
23 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
25 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
26 these are needed for sendmsg() and also for struct msghdr (at
27 least on Solaris). Solaris still won't build because struct msghdr
28 doesn't have msg_flags, msg_control, or msg_controllen members.
29 (CMSG_SPACE): Define for systems that don't have it.
32 2002-07-20 Dick Porter <dick@ximian.com>
38 * handles.c: Implemented pipe handles
41 * daemon.c: Fixed bug in handle closing.

46 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
48 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
51 2002-07-19 Martin Baulig <martin@gnome.org>
53 * threads.c (ExitThread): Call exit() if no threads has been
56 2002-07-17 Dick Porter <dick@ximian.com>
58 * daemon-messages.c: Freebsd fixes from Andreas Kohn
59 <andreas.kohn@gmx.net>
61 2002-07-15 Dick Porter <dick@ximian.com>
63 * io.c: Removed bogus console_flush() method, that was just cut
64 and pasted from file_flush when I separated the two handle types.
66 2002-07-12 Dick Porter <dick@ximian.com>
68 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
69 flags. Fixes bug 27633.
71 2002-07-12 Dick Porter <dick@ximian.com>
75 * daemon.c: Use size of sockaddr_un.sun_path from config.h
77 2002-07-12 Dick Porter <dick@ximian.com>
79 * processes.c (CreateProcess): Send stdin, stdout and stderr
80 handles if the startup info doesnt specify new ones
82 * io.c (GetStdHandle): Return the same handle when the same
83 standard handle is requested
85 * handles.c: Pass file descriptors when forking
87 * daemon.c: Use supplied file descriptors when forking a new
91 * daemon-messages.c: Pass stdin, stdout and stderr file
92 descriptors to the daemon (used when forking)
94 2002-07-11 Miguel de Icaza <miguel@ximian.com>
96 * daemon.c (_wapi_daemon_main): Use sizeof
97 (main_socket_address.sun_path) instead of hardcoded 108 value.
99 * handles.c (shared_init): Use sizeof
100 (shared_socket_address.sun_path) instead of hardcoded 108 value.
102 2002-07-10 Dennis Haney <davh@davh.dk>
106 * daemon.c: Lots of documentation, some added error checking, and
107 code readability improvements.
109 * daemon-messages.h: Add the Error request type to improve error
112 * daemon-messages.c: Do a bit more error checking on send() and
113 recv(), and log errors with a higher severity level.
115 2002-07-04 Dick Porter <dick@ximian.com>
117 * daemon.c (process_process_fork): Fix argument handling, due to
118 buggy understanding of g_strsplit() behaviour.
120 2002-07-03 Dick Porter <dick@ximian.com>
123 * threads.c: Implement OpenThread(). Define access-control values
129 * Makefile.am: Added access.h, to hold shared access-control
132 2002-07-02 Dick Porter <dick@ximian.com>
134 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
136 2002-07-02 Dick Porter <dick@ximian.com>
138 * handles.c (shared_init): Make a second attempt to contact the
139 daemon if the shared memory attach succeeds, but the connect()
140 fails. (This copes with the daemon crashing without cleaning up
146 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
147 the daemon, it's now built into the library.
149 2002-06-25 Dick Porter <dick@ximian.com>
154 * daemon.c: Process forking and handle data management
158 * processes.c: Process forking and other support functions
160 2002-06-25 Dick Porter <dick@ximian.com>
162 * versioninfo.h: PE resource decoding
164 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
165 to be told the string length
167 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
168 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
171 2002-06-12 Dick Porter <dick@ximian.com>
174 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
175 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
176 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
178 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
180 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
181 when writing to a closed socket.
183 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
185 * mono-mutex.c (mono_once): New convenience function for my
190 * critical-sections.c:
198 * atomic.c: Use mono_once() rather than pthread_once().
200 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
202 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
203 if multiple threads all try to call _wapi_handle_new() before the
204 shared data has been initialized, it is possible that we could get
205 into a condition where shared_init() is being executed and later
206 threads will pass by pthread_once() due to the fact that it has
207 already been called and so therefor will attempt to use the shared
208 data before it has been completely initialized. If we instead use
209 a standard mutex locking mechanism around shared_init(), we can
210 avoid the situation entirely. By wrapping the mutex locking in a
211 check to see if we've already initialized the data, we can even
212 avoid wasting resources by having to lock/unlock the mutex in any
213 later calls (the only time we'd have to worry about
214 locking/unlocking is the initial race to call shared_init() at
217 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
219 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
221 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
223 * daemon.c, handles.c: rename "sun" local var since it's apparently
224 a #define on Solaris.
226 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
228 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
231 2002-05-15 Dick Porter <dick@ximian.com>
233 * wait.c: Fix a deadlock in WaitForMultipleObjects
235 2002-05-14 Dick Porter <dick@ximian.com>
237 * io.c: Fix a cut&paste error, found by
238 Jaroslaw Kowalski <jarek@atm.com.pl>
240 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
244 2002-05-09 Dick Porter <dick@ximian.com>
252 * Makefile.am: Remove now-unused file wait-private.h
254 2002-05-08 Dick Porter <dick@ximian.com>
256 * shared.c: Better error messages, and report when daemon
257 connection fails rather than blocking forever. Do some more
258 shared memory sanity checking.
260 * handles.c: Better error messages when connecting to shared
261 memory and the handle daemon. Fall back to non-shared handles if
262 an error occurs. Set the default back to 'shared handles'. Fix a
263 crashing bug in scratch space allocation that mangled the block
266 2002-05-07 Miguel de Icaza <miguel@ximian.com>
268 * handles.c (shared_init): Disable SHM for now, people have too
269 many problems with this, and the diagnostics are not helping.
271 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
273 * io.c: CreateFile sets win32 last error.
275 2002-05-05 Dick Porter <dick@ximian.com>
286 * semaphore-private.h:
290 * event-private.h: Simplify the WapiHandleOps struct: take out all
291 the file-specific entries, leaving just the items that operate on
292 handles themselves. Split the close operation into shared and
293 private parts: shared close is called by the daemon.
295 * handles.c: As above, but also pass handle allocation, ref and
296 unref operations to the daemon. Populate the handle_ops array at
297 compile time, because the daemon needs to call ops on handles too.
298 Don't bother to track open handle counts any more, the daemon does
302 * thread-private.h: As above, but also make the thread data
305 * shared.c: Fork a handle daemon if the calling process created
306 the shared memory segment.
311 * Makefile.am: Build a daemon to manage handle allocation and
312 destruction without needing to lock the shared memory
314 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
316 * atomic.c: Changed to use a normal mutex rather than a spinlock
317 since a lot of platforms seem to not have them :\
319 2002-04-30 Dick Porter <dick@ximian.com>
321 * Completely rewrote the handle waiting code: removed the helper
322 thread and its attendant complexity. All handle waiting is now
323 abstracted into the WaitForSingleObject() and
324 WaitForMultipleObjects() functions.
326 * Implemented inter-process sharing of handles using sysv shared
327 memory. This makes handles even more opaque, with a handle now
328 just an index into an array.
330 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
332 * io.c: unitialized pointer in GetCurrentDirectory.
334 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
336 * threads.c: destroy the mutex at thread destruction
337 (if/when thread destruction code will be actually called).
338 When protecting a tls data pointer from the gc, use also the
339 thread id in the key.
341 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
343 * timed-thread.c: avoid race condition when setting the thread to
346 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
348 * jit.h: to more #include lines to avoid breaking compilation
349 under windows when upgrading mingw and w32api to version
352 2002-04-16 Dick Porter <dick@ximian.com>
354 * atomic.h: Explanatory comment about lack of 80386 support
356 2002-04-15 Dick Porter <dick@ximian.com>
358 * atomic.h: use xaddl for InterlockedIncrement() and
359 InterlockedDecrement(). Use cmpxchgl in a loop for
360 InterlockedExchange() and InterlockedExchangePointer().
362 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
364 * unicode.c: fix unicode_len() to not access uninitialized memory
365 (and updated to conform to mono code style).
367 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
369 * io.c: EEXISTS is ignored for directory creation.
370 * mono-mutex.h: remove silly "pragma }" that emacs users insert
371 because they use a broken editor:-)
373 2002-03-28 Dick Porter <dick@ximian.com>
379 * handles.c: Warning cleanups
381 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
383 * unicode.h, unicode.c: changed to gunichar2
384 * io.h, io.c: changed strings to gunichar2*, added
385 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
386 some fixes to FindFirstFile() and friends.

410 * atomic.c: Interlocked functions
412 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
414 * threads.c: use a gc-safe hash table to store tls pointers.
416 2002-03-22 Dick Porter <dick@ximian.com>
418 * threads.c: Fix a race condition where a thread can start and
419 exit before the handle has been properly initialised (no reason
420 why the handle couldn't be initialised beforehand, so do so)
422 Fix a ms to ns conversion magnitude thinko.
424 2002-03-21 Dick Porter <dick@ximian.com>
426 * semaphores.c: Fix a problem when waiting for one or more
427 semaphores, and another semaphore is Released (all waiting
428 semaphores assumed they were signalled)
430 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
432 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
433 RemoveDirectory, GetFileAttributes, GetFileAttributesEx

441 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
442 threads.c, io.c: added flush method to handles.
