1 2002-08-20 Dick Porter <dick@ximian.com>
3 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
4 multiples of 4 bytes, to keep header structures aligned. Needed
5 for sparc, at least. (Patch from crichton@gimp.org)
7 * handles.c: Removed 'disable_shm' variable (we've defaulted to
8 building with shm enabled for months now)
10 2002-08-19 Dick Porter <dick@ximian.com>
12 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
13 for legacy NeXT-based systems.
15 2002-08-12 Dick Porter <dick@ximian.com>
17 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
18 from Joseph Wenninger <kde@jowenn.at>)
20 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
22 * threads.c: use fast spinlocks by default
24 2002-08-02 Dick Porter <dick@ximian.com>
26 * io.c (GetStdHandle): Add a handle reference when returning a
27 duplicate console handle. This fixes the unref_handle errors in
30 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
32 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
35 2002-08-01 Dick Porter <dick@ximian.com>
37 * threads.c: Use atomic spinlocks in TLS functions
40 * Makefile.am: Added mono-spinlock.h
42 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
44 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
45 these are needed for sendmsg() and also for struct msghdr (at
46 least on Solaris). Solaris still won't build because struct msghdr
47 doesn't have msg_flags, msg_control, or msg_controllen members.
48 (CMSG_SPACE): Define for systems that don't have it.
51 2002-07-20 Dick Porter <dick@ximian.com>
57 * handles.c: Implemented pipe handles
60 * daemon.c: Fixed bug in handle closing.
63 * daemon.c: Forked processes now close all open file descriptors.
65 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
67 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
70 2002-07-19 Martin Baulig <martin@gnome.org>
72 * threads.c (ExitThread): Call exit() if no threads has been
75 2002-07-17 Dick Porter <dick@ximian.com>
77 * daemon-messages.c: Freebsd fixes from Andreas Kohn
78 <andreas.kohn@gmx.net>
80 2002-07-15 Dick Porter <dick@ximian.com>
82 * io.c: Removed bogus console_flush() method, that was just cut
83 and pasted from file_flush when I separated the two handle types.
85 2002-07-12 Dick Porter <dick@ximian.com>
87 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
88 flags. Fixes bug 27633.
90 2002-07-12 Dick Porter <dick@ximian.com>
94 * daemon.c: Use size of sockaddr_un.sun_path from config.h
96 2002-07-12 Dick Porter <dick@ximian.com>
98 * processes.c (CreateProcess): Send stdin, stdout and stderr
99 handles if the startup info doesnt specify new ones
101 * io.c (GetStdHandle): Return the same handle when the same
102 standard handle is requested
104 * handles.c: Pass file descriptors when forking
106 * daemon.c: Use supplied file descriptors when forking a new
110 * daemon-messages.c: Pass stdin, stdout and stderr file
111 descriptors to the daemon (used when forking)
113 2002-07-11 Miguel de Icaza <miguel@ximian.com>
115 * daemon.c (_wapi_daemon_main): Use sizeof
116 (main_socket_address.sun_path) instead of hardcoded 108 value.
118 * handles.c (shared_init): Use sizeof
119 (shared_socket_address.sun_path) instead of hardcoded 108 value.
121 2002-07-10 Dennis Haney <davh@davh.dk>
125 * daemon.c: Lots of documentation, some added error checking, and
126 code readability improvements.
128 * daemon-messages.h: Add the Error request type to improve error
131 * daemon-messages.c: Do a bit more error checking on send() and
132 recv(), and log errors with a higher severity level.
134 2002-07-04 Dick Porter <dick@ximian.com>
136 * daemon.c (process_process_fork): Fix argument handling, due to
137 buggy understanding of g_strsplit() behaviour.
139 2002-07-03 Dick Porter <dick@ximian.com>
142 * threads.c: Implement OpenThread(). Define access-control values
148 * Makefile.am: Added access.h, to hold shared access-control
151 2002-07-02 Dick Porter <dick@ximian.com>
153 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
155 2002-07-02 Dick Porter <dick@ximian.com>
157 * handles.c (shared_init): Make a second attempt to contact the
158 daemon if the shared memory attach succeeds, but the connect()
159 fails. (This copes with the daemon crashing without cleaning up
165 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
166 the daemon, it's now built into the library.
168 2002-06-25 Dick Porter <dick@ximian.com>
173 * daemon.c: Process forking and handle data management
177 * processes.c: Process forking and other support functions
179 2002-06-25 Dick Porter <dick@ximian.com>
181 * versioninfo.h: PE resource decoding
183 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
184 to be told the string length
186 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
187 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
190 2002-06-12 Dick Porter <dick@ximian.com>
193 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
194 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
195 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
197 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
199 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
200 when writing to a closed socket.
202 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
204 * mono-mutex.c (mono_once): New convenience function for my
209 * critical-sections.c:
217 * atomic.c: Use mono_once() rather than pthread_once().
219 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
221 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
222 if multiple threads all try to call _wapi_handle_new() before the
223 shared data has been initialized, it is possible that we could get
224 into a condition where shared_init() is being executed and later
225 threads will pass by pthread_once() due to the fact that it has
226 already been called and so therefor will attempt to use the shared
227 data before it has been completely initialized. If we instead use
228 a standard mutex locking mechanism around shared_init(), we can
229 avoid the situation entirely. By wrapping the mutex locking in a
230 check to see if we've already initialized the data, we can even
231 avoid wasting resources by having to lock/unlock the mutex in any
232 later calls (the only time we'd have to worry about
233 locking/unlocking is the initial race to call shared_init() at
236 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
238 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
240 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
242 * daemon.c, handles.c: rename "sun" local var since it's apparently
243 a #define on Solaris.
245 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
247 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
250 2002-05-15 Dick Porter <dick@ximian.com>
252 * wait.c: Fix a deadlock in WaitForMultipleObjects
254 2002-05-14 Dick Porter <dick@ximian.com>
256 * io.c: Fix a cut&paste error, found by
257 Jaroslaw Kowalski <jarek@atm.com.pl>
259 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
263 2002-05-09 Dick Porter <dick@ximian.com>
271 * Makefile.am: Remove now-unused file wait-private.h
273 2002-05-08 Dick Porter <dick@ximian.com>
275 * shared.c: Better error messages, and report when daemon
276 connection fails rather than blocking forever. Do some more
277 shared memory sanity checking.
279 * handles.c: Better error messages when connecting to shared
280 memory and the handle daemon. Fall back to non-shared handles if
281 an error occurs. Set the default back to 'shared handles'. Fix a
282 crashing bug in scratch space allocation that mangled the block
285 2002-05-07 Miguel de Icaza <miguel@ximian.com>
287 * handles.c (shared_init): Disable SHM for now, people have too
288 many problems with this, and the diagnostics are not helping.
290 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
292 * io.c: CreateFile sets win32 last error.
294 2002-05-05 Dick Porter <dick@ximian.com>
305 * semaphore-private.h:
309 * event-private.h: Simplify the WapiHandleOps struct: take out all
310 the file-specific entries, leaving just the items that operate on
311 handles themselves. Split the close operation into shared and
312 private parts: shared close is called by the daemon.
314 * handles.c: As above, but also pass handle allocation, ref and
315 unref operations to the daemon. Populate the handle_ops array at
316 compile time, because the daemon needs to call ops on handles too.
317 Don't bother to track open handle counts any more, the daemon does
321 * thread-private.h: As above, but also make the thread data
324 * shared.c: Fork a handle daemon if the calling process created
325 the shared memory segment.
330 * Makefile.am: Build a daemon to manage handle allocation and
331 destruction without needing to lock the shared memory
333 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
335 * atomic.c: Changed to use a normal mutex rather than a spinlock
336 since a lot of platforms seem to not have them :\
338 2002-04-30 Dick Porter <dick@ximian.com>
340 * Completely rewrote the handle waiting code: removed the helper
341 thread and its attendant complexity. All handle waiting is now
342 abstracted into the WaitForSingleObject() and
343 WaitForMultipleObjects() functions.
345 * Implemented inter-process sharing of handles using sysv shared
346 memory. This makes handles even more opaque, with a handle now
347 just an index into an array.
349 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
351 * io.c: unitialized pointer in GetCurrentDirectory.
353 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
355 * threads.c: destroy the mutex at thread destruction
356 (if/when thread destruction code will be actually called).
357 When protecting a tls data pointer from the gc, use also the
358 thread id in the key.
360 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
362 * timed-thread.c: avoid race condition when setting the thread to
365 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
367 * jit.h: to more #include lines to avoid breaking compilation
368 under windows when upgrading mingw and w32api to version
371 2002-04-16 Dick Porter <dick@ximian.com>
373 * atomic.h: Explanatory comment about lack of 80386 support
375 2002-04-15 Dick Porter <dick@ximian.com>
377 * atomic.h: use xaddl for InterlockedIncrement() and
378 InterlockedDecrement(). Use cmpxchgl in a loop for
379 InterlockedExchange() and InterlockedExchangePointer().
381 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
383 * unicode.c: fix unicode_len() to not access uninitialized memory
384 (and updated to conform to mono code style).
386 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
388 * io.c: EEXISTS is ignored for directory creation.
389 * mono-mutex.h: remove silly "pragma }" that emacs users insert
390 because they use a broken editor:-)
392 2002-03-28 Dick Porter <dick@ximian.com>
398 * handles.c: Warning cleanups
400 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
402 * unicode.h, unicode.c: changed to gunichar2
403 * io.h, io.c: changed strings to gunichar2*, added
404 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
405 some fixes to FindFirstFile() and friends.

431 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
433 * threads.c: use a gc-safe hash table to store tls pointers.
435 2002-03-22 Dick Porter <dick@ximian.com>
437 * threads.c: Fix a race condition where a thread can start and
438 exit before the handle has been properly initialised (no reason
439 why the handle couldn't be initialised beforehand, so do so)
441 Fix a ms to ns conversion magnitude thinko.
443 2002-03-21 Dick Porter <dick@ximian.com>
445 * semaphores.c: Fix a problem when waiting for one or more
446 semaphores, and another semaphore is Released (all waiting
447 semaphores assumed they were signalled)

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