5 * threads.c: Fixes for freebsd. Make sure that mutex and condition
6 creation and deletion happen in the process that owns them, when
7 POSIX shared thread objects aren't supported. This breaks on
8 freebsd, as pthread_t is a pointer to data.
10 2002-10-02 Dick Porter <dick@ximian.com>
12 * shared.c: Use mmap() instead of sysv shm for the shared data.
14 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
18 * daemon.c: mmap()ed regions survive fork, so just pass the
19 pointer to _wapi_daemon_main instead of mapping it again.
21 2002-10-01 Dick Porter <dick@ximian.com>
23 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
24 Unfortunately libgc uses the same thread suspend technique that I
25 want to, and the two don't mix: libgc will deadlock when it tries
26 to stop the world if a thread has already been suspended by
27 someone else. Just do the simple suspended create rather than the
28 general purpose thread suspension for now.
30 * threads.c: Pass create flags to the timed_thread create call, to
31 implement suspended thread creation. ResumeThread() partially
32 implemented, to cope with the case where a newly created but
33 suspended thread is launched.
35 2002-09-30 Dick Porter <dick@ximian.com>
37 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
40 2002-09-27 Dick Porter <dick@ximian.com>
42 * semaphores.c: Only include semaphore.h if it's present. Patch
43 for BSD from jmmv@hispabsd.org (Julio Merino).
45 2002-09-27 Dick Porter <dick@ximian.com>
47 * processes.c: Pass environment and working directory to the
48 daemon when forking. Don't let argv[0] be duplicated when looking
49 for the program name. Implement EnumProcessModules (simple
50 version for now, lsof-style later if needed), GetModuleBaseName,
51 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
52 aren't available on Linux).
54 * process-private.h: Store the process name, and the working set
58 * handles-private.h: New functions to store and retrieve an array
59 of strings in the scratch space
61 * daemon.c: Don't miss deleting some handles when a client exits
62 (we used to rely on the client doing the final cleanup, but
63 obviously if the client is no longer there the daemon has to do
66 Process forking now sets the environment and the working
69 * io.c: Don't confuse fd 0 with an unassigned handle struct
71 * atomic.h: Add a google cache alternative to the msdn URL
73 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
76 (_wapi_recvfrom): added ECONNRESET to the switch.
78 2002-09-24 Mark Crichton <crichton@gimp.org>
80 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
83 2002-09-19 Mark Crichton <crichton@gimp.org>
85 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
86 dont have Linux's abstract filesystem for sockets.
88 2002-09-19 Mark Crichton <crichton@gimp.org>
90 * atomic.h: Added SPARC atomic asm code.
91 * daemon.c, handles-private.h, handles.c, wapi-private.h:
92 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
93 Solaris 9, however, the code paths don't seem to work. More testing
94 on the shared case is *really* needed.
96 2002-09-03 Dick Porter <dick@ximian.com>
99 * threads.c: Removed PosixKillThread(), because it's not in the
102 2002-08-20 Dick Porter <dick@ximian.com>
104 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
105 multiples of 4 bytes, to keep header structures aligned. Needed
106 for sparc, at least. (Patch from crichton@gimp.org)
108 * handles.c: Removed 'disable_shm' variable (we've defaulted to
109 building with shm enabled for months now)
111 2002-08-19 Dick Porter <dick@ximian.com>
113 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
114 for legacy NeXT-based systems.
116 2002-08-12 Dick Porter <dick@ximian.com>
118 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
119 from Joseph Wenninger <kde@jowenn.at>)
121 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
123 * threads.c: use fast spinlocks by default
125 2002-08-02 Dick Porter <dick@ximian.com>
127 * io.c (GetStdHandle): Add a handle reference when returning a
128 duplicate console handle. This fixes the unref_handle errors in
131 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
133 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
136 2002-08-01 Dick Porter <dick@ximian.com>
138 * threads.c: Use atomic spinlocks in TLS functions
141 * Makefile.am: Added mono-spinlock.h
143 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
145 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
146 these are needed for sendmsg() and also for struct msghdr (at
147 least on Solaris). Solaris still won't build because struct msghdr
148 doesn't have msg_flags, msg_control, or msg_controllen members.
149 (CMSG_SPACE): Define for systems that don't have it.
152 2002-07-20 Dick Porter <dick@ximian.com>
158 * handles.c: Implemented pipe handles
161 * daemon.c: Fixed bug in handle closing.
164 * daemon.c: Forked processes now close all open file descriptors.
166 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
168 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
171 2002-07-19 Martin Baulig <martin@gnome.org>
173 * threads.c (ExitThread): Call exit() if no threads has been
176 2002-07-17 Dick Porter <dick@ximian.com>
178 * daemon-messages.c: Freebsd fixes from Andreas Kohn
179 <andreas.kohn@gmx.net>
181 2002-07-15 Dick Porter <dick@ximian.com>
183 * io.c: Removed bogus console_flush() method, that was just cut
184 and pasted from file_flush when I separated the two handle types.
186 2002-07-12 Dick Porter <dick@ximian.com>
188 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
189 flags. Fixes bug 27633.
191 2002-07-12 Dick Porter <dick@ximian.com>
195 * daemon.c: Use size of sockaddr_un.sun_path from config.h
197 2002-07-12 Dick Porter <dick@ximian.com>
199 * processes.c (CreateProcess): Send stdin, stdout and stderr
200 handles if the startup info doesnt specify new ones
202 * io.c (GetStdHandle): Return the same handle when the same
203 standard handle is requested
205 * handles.c: Pass file descriptors when forking
207 * daemon.c: Use supplied file descriptors when forking a new
211 * daemon-messages.c: Pass stdin, stdout and stderr file
212 descriptors to the daemon (used when forking)
214 2002-07-11 Miguel de Icaza <miguel@ximian.com>
216 * daemon.c (_wapi_daemon_main): Use sizeof
217 (main_socket_address.sun_path) instead of hardcoded 108 value.
219 * handles.c (shared_init): Use sizeof
220 (shared_socket_address.sun_path) instead of hardcoded 108 value.
222 2002-07-10 Dennis Haney <davh@davh.dk>
226 * daemon.c: Lots of documentation, some added error checking, and
227 code readability improvements.
229 * daemon-messages.h: Add the Error request type to improve error
232 * daemon-messages.c: Do a bit more error checking on send() and
233 recv(), and log errors with a higher severity level.
235 2002-07-04 Dick Porter <dick@ximian.com>
237 * daemon.c (process_process_fork): Fix argument handling, due to
238 buggy understanding of g_strsplit() behaviour.
240 2002-07-03 Dick Porter <dick@ximian.com>
243 * threads.c: Implement OpenThread(). Define access-control values
249 * Makefile.am: Added access.h, to hold shared access-control
252 2002-07-02 Dick Porter <dick@ximian.com>
254 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
256 2002-07-02 Dick Porter <dick@ximian.com>
258 * handles.c (shared_init): Make a second attempt to contact the
259 daemon if the shared memory attach succeeds, but the connect()
260 fails. (This copes with the daemon crashing without cleaning up
266 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
267 the daemon, it's now built into the library.
269 2002-06-25 Dick Porter <dick@ximian.com>
274 * daemon.c: Process forking and handle data management
278 * processes.c: Process forking and other support functions
280 2002-06-25 Dick Porter <dick@ximian.com>
282 * versioninfo.h: PE resource decoding
284 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
285 to be told the string length
287 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
288 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
291 2002-06-12 Dick Porter <dick@ximian.com>
294 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
295 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
296 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
298 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
300 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
301 when writing to a closed socket.
303 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
305 * mono-mutex.c (mono_once): New convenience function for my
310 * critical-sections.c:
318 * atomic.c: Use mono_once() rather than pthread_once().
320 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
322 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
323 if multiple threads all try to call _wapi_handle_new() before the
324 shared data has been initialized, it is possible that we could get
325 into a condition where shared_init() is being executed and later
326 threads will pass by pthread_once() due to the fact that it has
327 already been called and so therefor will attempt to use the shared
328 data before it has been completely initialized. If we instead use
329 a standard mutex locking mechanism around shared_init(), we can
330 avoid the situation entirely. By wrapping the mutex locking in a
331 check to see if we've already initialized the data, we can even
332 avoid wasting resources by having to lock/unlock the mutex in any
333 later calls (the only time we'd have to worry about
334 locking/unlocking is the initial race to call shared_init() at
337 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
339 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
341 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
343 * daemon.c, handles.c: rename "sun" local var since it's apparently
344 a #define on Solaris.
346 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
348 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
351 2002-05-15 Dick Porter <dick@ximian.com>
353 * wait.c: Fix a deadlock in WaitForMultipleObjects
355 2002-05-14 Dick Porter <dick@ximian.com>
357 * io.c: Fix a cut&paste error, found by
358 Jaroslaw Kowalski <jarek@atm.com.pl>
360 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
364 2002-05-09 Dick Porter <dick@ximian.com>
372 * Makefile.am: Remove now-unused file wait-private.h
374 2002-05-08 Dick Porter <dick@ximian.com>
376 * shared.c: Better error messages, and report when daemon
377 connection fails rather than blocking forever. Do some more
378 shared memory sanity checking.
380 * handles.c: Better error messages when connecting to shared
381 memory and the handle daemon. Fall back to non-shared handles if
382 an error occurs. Set the default back to 'shared handles'. Fix a
383 crashing bug in scratch space allocation that mangled the block
386 2002-05-07 Miguel de Icaza <miguel@ximian.com>
388 * handles.c (shared_init): Disable SHM for now, people have too
389 many problems with this, and the diagnostics are not helping.
391 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
393 * io.c: CreateFile sets win32 last error.
395 2002-05-05 Dick Porter <dick@ximian.com>
406 * semaphore-private.h:
410 * event-private.h: Simplify the WapiHandleOps struct: take out all
411 the file-specific entries, leaving just the items that operate on
412 handles themselves. Split the close operation into shared and
413 private parts: shared close is called by the daemon.
415 * handles.c: As above, but also pass handle allocation, ref and
416 unref operations to the daemon. Populate the handle_ops array at
417 compile time, because the daemon needs to call ops on handles too.
418 Don't bother to track open handle counts any more, the daemon does
422 * thread-private.h: As above, but also make the thread data
425 * shared.c: Fork a handle daemon if the calling process created
426 the shared memory segment.
431 * Makefile.am: Build a daemon to manage handle allocation and
432 destruction without needing to lock the shared memory
434 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
436 * atomic.c: Changed to use a normal mutex rather than a spinlock
437 since a lot of platforms seem to not have them :\
439 2002-04-30 Dick Porter <dick@ximian.com>
441 * Completely rewrote the handle waiting code: removed the helper
442 thread and its attendant complexity. All handle waiting is now
443 abstracted into the WaitForSingleObject() and
444 WaitForMultipleObjects() functions.
446 * Implemented inter-process sharing of handles using sysv shared
447 memory. This makes handles even more opaque, with a handle now
448 just an index into an array.
450 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
452 * io.c: unitialized pointer in GetCurrentDirectory.
454 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
456 * threads.c: destroy the mutex at thread destruction
457 (if/when thread destruction code will be actually called).
458 When protecting a tls data pointer from the gc, use also the
459 thread id in the key.
461 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
463 * timed-thread.c: avoid race condition when setting the thread to
466 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
468 * jit.h: to more #include lines to avoid breaking compilation
469 under windows when upgrading mingw and w32api to version
472 2002-04-16 Dick Porter <dick@ximian.com>
474 * atomic.h: Explanatory comment about lack of 80386 support
476 2002-04-15 Dick Porter <dick@ximian.com>
478 * atomic.h: use xaddl for InterlockedIncrement() and
479 InterlockedDecrement(). Use cmpxchgl in a loop for
480 InterlockedExchange() and InterlockedExchangePointer().
482 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
484 * unicode.c: fix unicode_len() to not access uninitialized memory
485 (and updated to conform to mono code style).
487 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
489 * io.c: EEXISTS is ignored for directory creation.
490 * mono-mutex.h: remove silly "pragma }" that emacs users insert
491 because they use a broken editor:-)
493 2002-03-28 Dick Porter <dick@ximian.com>
499 * handles.c: Warning cleanups
501 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
503 * unicode.h, unicode.c: changed to gunichar2
504 * io.h, io.c: changed strings to gunichar2*, added
505 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
506 some fixes to FindFirstFile() and friends.
508 2002-03-26 Dick Porter <dick@ximian.com>
510 * types.h: Implement the large integer struct

520 * system.c: Beginnings of GetSystemInfo()
522 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
526 * context.c: Dummy function that doesnt yet implement
530 * atomic.c: Interlocked functions
532 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
534 * threads.c: use a gc-safe hash table to store tls pointers.
536 2002-03-22 Dick Porter <dick@ximian.com>
538 * threads.c: Fix a race condition where a thread can start and
539 exit before the handle has been properly initialised (no reason
540 why the handle couldn't be initialised beforehand, so do so)
542 Fix a ms to ns conversion magnitude thinko.
544 2002-03-21 Dick Porter <dick@ximian.com>
546 * semaphores.c: Fix a problem when waiting for one or more
547 semaphores, and another semaphore is Released (all waiting
548 semaphores assumed they were signalled)
550 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
552 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
553 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
555 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
557 * threads.c (Sleep): bug fix: 1ms == 1000000ns
559 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
561 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
562 threads.c, io.c: added flush method to handles.
564 * io.c: FlushFileBuffers() and FindFirstFile() functions.
566 Thu Mar 7 17:21:52 CET 2002 Paolo Molaro <lupus@ximian.com>

596 arguments for the sake of portability. Implements recursive
597 mutexes and pthread_mutex_timedlock.

606 * wait.c: Use the mono-mutex wrapper portability functions/macros.
608 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
610 2002-01-23 Dick Porter <dick@ximian.com>
612 * sockets.c: Networking support, mostly wrapping BSD socket APIs
613 with handle code, and translating errno into w32 error codes.
