1 2002-10-07 Dick Porter <dick@ximian.com>
4 * daemon.c: Use a more accurate time source for process start and
7 2002-10-03 Dick Porter <dick@ximian.com>
11 * threads.c: Fixes for freebsd. Make sure that mutex and condition
12 creation and deletion happen in the process that owns them, when
13 POSIX shared thread objects aren't supported. This breaks on
14 freebsd, as pthread_t is a pointer to data.
16 2002-10-02 Dick Porter <dick@ximian.com>
18 * shared.c: Use mmap() instead of sysv shm for the shared data.
20 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
24 * daemon.c: mmap()ed regions survive fork, so just pass the
25 pointer to _wapi_daemon_main instead of mapping it again.
27 2002-10-01 Dick Porter <dick@ximian.com>
29 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
30 Unfortunately libgc uses the same thread suspend technique that I
31 want to, and the two don't mix: libgc will deadlock when it tries
32 to stop the world if a thread has already been suspended by
33 someone else. Just do the simple suspended create rather than the
34 general purpose thread suspension for now.
36 * threads.c: Pass create flags to the timed_thread create call, to
37 implement suspended thread creation. ResumeThread() partially
38 implemented, to cope with the case where a newly created but
39 suspended thread is launched.
41 2002-09-30 Dick Porter <dick@ximian.com>
43 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
46 2002-09-27 Dick Porter <dick@ximian.com>
48 * semaphores.c: Only include semaphore.h if it's present. Patch
49 for BSD from jmmv@hispabsd.org (Julio Merino).
51 2002-09-27 Dick Porter <dick@ximian.com>
53 * processes.c: Pass environment and working directory to the
54 daemon when forking. Don't let argv[0] be duplicated when looking
55 for the program name. Implement EnumProcessModules (simple
56 version for now, lsof-style later if needed), GetModuleBaseName,
57 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
58 aren't available on Linux).
60 * process-private.h: Store the process name, and the working set
64 * handles-private.h: New functions to store and retrieve an array
65 of strings in the scratch space
67 * daemon.c: Don't miss deleting some handles when a client exits
68 (we used to rely on the client doing the final cleanup, but
69 obviously if the client is no longer there the daemon has to do
72 Process forking now sets the environment and the working
75 * io.c: Don't confuse fd 0 with an unassigned handle struct
77 * atomic.h: Add a google cache alternative to the msdn URL
79 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
82 (_wapi_recvfrom): added ECONNRESET to the switch.
84 2002-09-24 Mark Crichton <crichton@gimp.org>
86 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
89 2002-09-19 Mark Crichton <crichton@gimp.org>
91 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
92 dont have Linux's abstract filesystem for sockets.
94 2002-09-19 Mark Crichton <crichton@gimp.org>
96 * atomic.h: Added SPARC atomic asm code.
97 * daemon.c, handles-private.h, handles.c, wapi-private.h:
98 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
99 Solaris 9, however, the code paths don't seem to work. More testing
100 on the shared case is *really* needed.
102 2002-09-03 Dick Porter <dick@ximian.com>
105 * threads.c: Removed PosixKillThread(), because it's not in the
108 2002-08-20 Dick Porter <dick@ximian.com>
110 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
111 multiples of 4 bytes, to keep header structures aligned. Needed
112 for sparc, at least. (Patch from crichton@gimp.org)
114 * handles.c: Removed 'disable_shm' variable (we've defaulted to
115 building with shm enabled for months now)
117 2002-08-19 Dick Porter <dick@ximian.com>
119 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
120 for legacy NeXT-based systems.
122 2002-08-12 Dick Porter <dick@ximian.com>
124 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
125 from Joseph Wenninger <kde@jowenn.at>)
127 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
129 * threads.c: use fast spinlocks by default
131 2002-08-02 Dick Porter <dick@ximian.com>
133 * io.c (GetStdHandle): Add a handle reference when returning a
134 duplicate console handle. This fixes the unref_handle errors in
137 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
139 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
142 2002-08-01 Dick Porter <dick@ximian.com>
144 * threads.c: Use atomic spinlocks in TLS functions
147 * Makefile.am: Added mono-spinlock.h
149 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
151 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
152 these are needed for sendmsg() and also for struct msghdr (at
153 least on Solaris). Solaris still won't build because struct msghdr
154 doesn't have msg_flags, msg_control, or msg_controllen members.
155 (CMSG_SPACE): Define for systems that don't have it.
158 2002-07-20 Dick Porter <dick@ximian.com>
164 * handles.c: Implemented pipe handles
167 * daemon.c: Fixed bug in handle closing.
170 * daemon.c: Forked processes now close all open file descriptors.
172 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
174 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
177 2002-07-19 Martin Baulig <martin@gnome.org>
179 * threads.c (ExitThread): Call exit() if no threads has been
182 2002-07-17 Dick Porter <dick@ximian.com>
184 * daemon-messages.c: Freebsd fixes from Andreas Kohn
185 <andreas.kohn@gmx.net>
187 2002-07-15 Dick Porter <dick@ximian.com>
189 * io.c: Removed bogus console_flush() method, that was just cut
190 and pasted from file_flush when I separated the two handle types.
192 2002-07-12 Dick Porter <dick@ximian.com>
194 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
195 flags. Fixes bug 27633.
197 2002-07-12 Dick Porter <dick@ximian.com>
201 * daemon.c: Use size of sockaddr_un.sun_path from config.h
203 2002-07-12 Dick Porter <dick@ximian.com>
205 * processes.c (CreateProcess): Send stdin, stdout and stderr
206 handles if the startup info doesnt specify new ones
208 * io.c (GetStdHandle): Return the same handle when the same
209 standard handle is requested
211 * handles.c: Pass file descriptors when forking
213 * daemon.c: Use supplied file descriptors when forking a new
217 * daemon-messages.c: Pass stdin, stdout and stderr file
218 descriptors to the daemon (used when forking)
220 2002-07-11 Miguel de Icaza <miguel@ximian.com>
222 * daemon.c (_wapi_daemon_main): Use sizeof
223 (main_socket_address.sun_path) instead of hardcoded 108 value.
225 * handles.c (shared_init): Use sizeof
226 (shared_socket_address.sun_path) instead of hardcoded 108 value.
228 2002-07-10 Dennis Haney <davh@davh.dk>
232 * daemon.c: Lots of documentation, some added error checking, and
233 code readability improvements.
235 * daemon-messages.h: Add the Error request type to improve error
238 * daemon-messages.c: Do a bit more error checking on send() and
239 recv(), and log errors with a higher severity level.
241 2002-07-04 Dick Porter <dick@ximian.com>
243 * daemon.c (process_process_fork): Fix argument handling, due to
244 buggy understanding of g_strsplit() behaviour.
246 2002-07-03 Dick Porter <dick@ximian.com>
249 * threads.c: Implement OpenThread(). Define access-control values
255 * Makefile.am: Added access.h, to hold shared access-control
258 2002-07-02 Dick Porter <dick@ximian.com>
260 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
262 2002-07-02 Dick Porter <dick@ximian.com>
264 * handles.c (shared_init): Make a second attempt to contact the
265 daemon if the shared memory attach succeeds, but the connect()
266 fails. (This copes with the daemon crashing without cleaning up
272 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
273 the daemon, it's now built into the library.
275 2002-06-25 Dick Porter <dick@ximian.com>
280 * daemon.c: Process forking and handle data management
284 * processes.c: Process forking and other support functions
286 2002-06-25 Dick Porter <dick@ximian.com>
288 * versioninfo.h: PE resource decoding
290 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
291 to be told the string length
293 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
294 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
297 2002-06-12 Dick Porter <dick@ximian.com>
300 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
301 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
302 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
304 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
306 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
307 when writing to a closed socket.
309 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
311 * mono-mutex.c (mono_once): New convenience function for my
316 * critical-sections.c:
324 * atomic.c: Use mono_once() rather than pthread_once().
326 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
328 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
329 if multiple threads all try to call _wapi_handle_new() before the
330 shared data has been initialized, it is possible that we could get
331 into a condition where shared_init() is being executed and later
332 threads will pass by pthread_once() due to the fact that it has
333 already been called and so therefor will attempt to use the shared
334 data before it has been completely initialized. If we instead use
335 a standard mutex locking mechanism around shared_init(), we can
336 avoid the situation entirely. By wrapping the mutex locking in a
337 check to see if we've already initialized the data, we can even
338 avoid wasting resources by having to lock/unlock the mutex in any
339 later calls (the only time we'd have to worry about
340 locking/unlocking is the initial race to call shared_init() at
343 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
345 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
347 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
349 * daemon.c, handles.c: rename "sun" local var since it's apparently
350 a #define on Solaris.
352 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
354 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
357 2002-05-15 Dick Porter <dick@ximian.com>
359 * wait.c: Fix a deadlock in WaitForMultipleObjects
361 2002-05-14 Dick Porter <dick@ximian.com>
363 * io.c: Fix a cut&paste error, found by
364 Jaroslaw Kowalski <jarek@atm.com.pl>
366 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
370 2002-05-09 Dick Porter <dick@ximian.com>
378 * Makefile.am: Remove now-unused file wait-private.h
380 2002-05-08 Dick Porter <dick@ximian.com>
382 * shared.c: Better error messages, and report when daemon
383 connection fails rather than blocking forever. Do some more
384 shared memory sanity checking.
386 * handles.c: Better error messages when connecting to shared
387 memory and the handle daemon. Fall back to non-shared handles if
388 an error occurs. Set the default back to 'shared handles'. Fix a
389 crashing bug in scratch space allocation that mangled the block
392 2002-05-07 Miguel de Icaza <miguel@ximian.com>
394 * handles.c (shared_init): Disable SHM for now, people have too
395 many problems with this, and the diagnostics are not helping.
397 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
399 * io.c: CreateFile sets win32 last error.
401 2002-05-05 Dick Porter <dick@ximian.com>
412 * semaphore-private.h:
416 * event-private.h: Simplify the WapiHandleOps struct: take out all
417 the file-specific entries, leaving just the items that operate on
418 handles themselves. Split the close operation into shared and
419 private parts: shared close is called by the daemon.
421 * handles.c: As above, but also pass handle allocation, ref and
422 unref operations to the daemon. Populate the handle_ops array at
423 compile time, because the daemon needs to call ops on handles too.
424 Don't bother to track open handle counts any more, the daemon does
428 * thread-private.h: As above, but also make the thread data
431 * shared.c: Fork a handle daemon if the calling process created
432 the shared memory segment.
437 * Makefile.am: Build a daemon to manage handle allocation and
438 destruction without needing to lock the shared memory
440 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
442 * atomic.c: Changed to use a normal mutex rather than a spinlock
443 since a lot of platforms seem to not have them :\
445 2002-04-30 Dick Porter <dick@ximian.com>
447 * Completely rewrote the handle waiting code: removed the helper
448 thread and its attendant complexity. All handle waiting is now
449 abstracted into the WaitForSingleObject() and
450 WaitForMultipleObjects() functions.
452 * Implemented inter-process sharing of handles using sysv shared
453 memory. This makes handles even more opaque, with a handle now
454 just an index into an array.
456 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
458 * io.c: unitialized pointer in GetCurrentDirectory.
460 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
462 * threads.c: destroy the mutex at thread destruction
463 (if/when thread destruction code will be actually called).
464 When protecting a tls data pointer from the gc, use also the
465 thread id in the key.
467 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
469 * timed-thread.c: avoid race condition when setting the thread to
472 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
474 * jit.h: to more #include lines to avoid breaking compilation
475 under windows when upgrading mingw and w32api to version
478 2002-04-16 Dick Porter <dick@ximian.com>
480 * atomic.h: Explanatory comment about lack of 80386 support
482 2002-04-15 Dick Porter <dick@ximian.com>
484 * atomic.h: use xaddl for InterlockedIncrement() and
485 InterlockedDecrement(). Use cmpxchgl in a loop for
486 InterlockedExchange() and InterlockedExchangePointer().
488 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
490 * unicode.c: fix unicode_len() to not access uninitialized memory
491 (and updated to conform to mono code style).
493 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
495 * io.c: EEXISTS is ignored for directory creation.
496 * mono-mutex.h: remove silly "pragma }" that emacs users insert
497 because they use a broken editor:-)
499 2002-03-28 Dick Porter <dick@ximian.com>
505 * handles.c: Warning cleanups
507 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
509 * unicode.h, unicode.c: changed to gunichar2
510 * io.h, io.c: changed strings to gunichar2*, added
511 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
512 some fixes to FindFirstFile() and friends.
514 2002-03-26 Dick Porter <dick@ximian.com>
516 * types.h: Implement the large integer struct
519 * timefuncs.c: Dummy functions that don't yet implement
520 QueryPerformanceCounter() and QueryPerformanceFrequency()
523 * threads.c: Implement SleepEx()
526 * system.c: Beginnings of GetSystemInfo()
528 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
532 * context.c: Dummy function that doesnt yet implement
536 * atomic.c: Interlocked functions
538 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
540 * threads.c: use a gc-safe hash table to store tls pointers.
542 2002-03-22 Dick Porter <dick@ximian.com>
544 * threads.c: Fix a race condition where a thread can start and
545 exit before the handle has been properly initialised (no reason
546 why the handle couldn't be initialised beforehand, so do so)
548 Fix a ms to ns conversion magnitude thinko.
550 2002-03-21 Dick Porter <dick@ximian.com>
552 * semaphores.c: Fix a problem when waiting for one or more
553 semaphores, and another semaphore is Released (all waiting
554 semaphores assumed they were signalled)
556 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
558 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
559 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
561 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
563 * threads.c (Sleep): bug fix: 1ms == 1000000ns
565 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
567 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
568 threads.c, io.c: added flush method to handles.
570 * io.c: FlushFileBuffers() and FindFirstFile() functions.
572 Thu Mar 7 17:21:52 CET 2002 Paolo Molaro <lupus@ximian.com>
574 * threads.c, timed-thread.c, wait.c: Boehm-GC anable.

586 * io-layer.h: conditionally include sys/filio.h and sys/sockio.h
587 for FIONBIO, FIONREAD, and SIOCATMARK.
589 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
591 * sockets.c: conditionally include sys/filio.h and sys/sockio.h

602 arguments for the sake of portability. Implements recursive
603 mutexes and pthread_mutex_timedlock.
605 * critical-sections.c:
612 * wait.c: Use the mono-mutex wrapper portability functions/macros.
614 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
616 2002-01-23 Dick Porter <dick@ximian.com>
618 * sockets.c: Networking support, mostly wrapping BSD socket APIs
619 with handle code, and translating errno into w32 error codes.

728 2001-11-08 Dick Porter <dick@ximian.com>
732 This is a library emulating the win32 threading and IO API.
