1 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
3 * threads.c (TlsGetValue): removed unnecessary mutex
5 2002-11-20 Dick Porter <dick@ximian.com>
7 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
8 need to store their data structure too.
10 * threads.c: Make sure the threading data is initialised wherever
13 2002-11-15 Dick Porter <dick@ximian.com>
15 * timed-thread.c: Removed unneeded parameters in
16 _wapi_timed_thread_attach().
18 * threads.c: Renamed AttachThread() to make it not look like
19 external API. Removed unneeded parameters.
21 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
23 * error.[ch]: added errno_to_WSA (). It displays a warning and return
24 WSASYSCALLFAILURE if there is no error mapping for the given errno,
26 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
28 2002-10-31 Dick Porter <dick@ximian.com>
31 * io.c: Define and use INVALID_FILE_ATTRIBUTES
33 2002-10-07 Dick Porter <dick@ximian.com>
36 * daemon.c: Use a more accurate time source for process start and
39 2002-10-03 Dick Porter <dick@ximian.com>
43 * threads.c: Fixes for freebsd. Make sure that mutex and condition
44 creation and deletion happen in the process that owns them, when
45 POSIX shared thread objects aren't supported. This breaks on
46 freebsd, as pthread_t is a pointer to data.
48 2002-10-02 Dick Porter <dick@ximian.com>
50 * shared.c: Use mmap() instead of sysv shm for the shared data.
52 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
56 * daemon.c: mmap()ed regions survive fork, so just pass the
57 pointer to _wapi_daemon_main instead of mapping it again.
59 2002-10-01 Dick Porter <dick@ximian.com>
61 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
62 Unfortunately libgc uses the same thread suspend technique that I
63 want to, and the two don't mix: libgc will deadlock when it tries
64 to stop the world if a thread has already been suspended by
65 someone else. Just do the simple suspended create rather than the
66 general purpose thread suspension for now.
68 * threads.c: Pass create flags to the timed_thread create call, to
69 implement suspended thread creation. ResumeThread() partially
70 implemented, to cope with the case where a newly created but
71 suspended thread is launched.
73 2002-09-30 Dick Porter <dick@ximian.com>
75 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
78 2002-09-27 Dick Porter <dick@ximian.com>
80 * semaphores.c: Only include semaphore.h if it's present. Patch
81 for BSD from jmmv@hispabsd.org (Julio Merino).
83 2002-09-27 Dick Porter <dick@ximian.com>
85 * processes.c: Pass environment and working directory to the
86 daemon when forking. Don't let argv[0] be duplicated when looking
87 for the program name. Implement EnumProcessModules (simple
88 version for now, lsof-style later if needed), GetModuleBaseName,
89 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
90 aren't available on Linux).
92 * process-private.h: Store the process name, and the working set
96 * handles-private.h: New functions to store and retrieve an array
97 of strings in the scratch space
99 * daemon.c: Don't miss deleting some handles when a client exits
100 (we used to rely on the client doing the final cleanup, but
101 obviously if the client is no longer there the daemon has to do
104 Process forking now sets the environment and the working
107 * io.c: Don't confuse fd 0 with an unassigned handle struct
109 * atomic.h: Add a google cache alternative to the msdn URL
111 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
114 (_wapi_recvfrom): added ECONNRESET to the switch.
116 2002-09-24 Mark Crichton <crichton@gimp.org>
118 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
121 2002-09-19 Mark Crichton <crichton@gimp.org>
123 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
124 dont have Linux's abstract filesystem for sockets.
126 2002-09-19 Mark Crichton <crichton@gimp.org>
128 * atomic.h: Added SPARC atomic asm code.
129 * daemon.c, handles-private.h, handles.c, wapi-private.h:
130 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
131 Solaris 9, however, the code paths don't seem to work. More testing
132 on the shared case is *really* needed.
134 2002-09-03 Dick Porter <dick@ximian.com>
137 * threads.c: Removed PosixKillThread(), because it's not in the
140 2002-08-20 Dick Porter <dick@ximian.com>
142 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
143 multiples of 4 bytes, to keep header structures aligned. Needed
144 for sparc, at least. (Patch from crichton@gimp.org)
146 * handles.c: Removed 'disable_shm' variable (we've defaulted to
147 building with shm enabled for months now)
149 2002-08-19 Dick Porter <dick@ximian.com>
151 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
152 for legacy NeXT-based systems.
154 2002-08-12 Dick Porter <dick@ximian.com>
156 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
157 from Joseph Wenninger <kde@jowenn.at>)
159 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
161 * threads.c: use fast spinlocks by default
163 2002-08-02 Dick Porter <dick@ximian.com>
165 * io.c (GetStdHandle): Add a handle reference when returning a
166 duplicate console handle. This fixes the unref_handle errors in
169 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
171 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
174 2002-08-01 Dick Porter <dick@ximian.com>
176 * threads.c: Use atomic spinlocks in TLS functions
179 * Makefile.am: Added mono-spinlock.h
181 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
183 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
184 these are needed for sendmsg() and also for struct msghdr (at
185 least on Solaris). Solaris still won't build because struct msghdr
186 doesn't have msg_flags, msg_control, or msg_controllen members.
187 (CMSG_SPACE): Define for systems that don't have it.
190 2002-07-20 Dick Porter <dick@ximian.com>
196 * handles.c: Implemented pipe handles
199 * daemon.c: Fixed bug in handle closing.
202 * daemon.c: Forked processes now close all open file descriptors.
204 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
206 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
209 2002-07-19 Martin Baulig <martin@gnome.org>
211 * threads.c (ExitThread): Call exit() if no threads has been
214 2002-07-17 Dick Porter <dick@ximian.com>
216 * daemon-messages.c: Freebsd fixes from Andreas Kohn
217 <andreas.kohn@gmx.net>
219 2002-07-15 Dick Porter <dick@ximian.com>
221 * io.c: Removed bogus console_flush() method, that was just cut
222 and pasted from file_flush when I separated the two handle types.
224 2002-07-12 Dick Porter <dick@ximian.com>
226 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
227 flags. Fixes bug 27633.
229 2002-07-12 Dick Porter <dick@ximian.com>
233 * daemon.c: Use size of sockaddr_un.sun_path from config.h
235 2002-07-12 Dick Porter <dick@ximian.com>
237 * processes.c (CreateProcess): Send stdin, stdout and stderr
238 handles if the startup info doesnt specify new ones
240 * io.c (GetStdHandle): Return the same handle when the same
241 standard handle is requested
243 * handles.c: Pass file descriptors when forking
245 * daemon.c: Use supplied file descriptors when forking a new
249 * daemon-messages.c: Pass stdin, stdout and stderr file
250 descriptors to the daemon (used when forking)
252 2002-07-11 Miguel de Icaza <miguel@ximian.com>
254 * daemon.c (_wapi_daemon_main): Use sizeof
255 (main_socket_address.sun_path) instead of hardcoded 108 value.
257 * handles.c (shared_init): Use sizeof
258 (shared_socket_address.sun_path) instead of hardcoded 108 value.
260 2002-07-10 Dennis Haney <davh@davh.dk>
264 * daemon.c: Lots of documentation, some added error checking, and
265 code readability improvements.
267 * daemon-messages.h: Add the Error request type to improve error
270 * daemon-messages.c: Do a bit more error checking on send() and
271 recv(), and log errors with a higher severity level.
273 2002-07-04 Dick Porter <dick@ximian.com>
275 * daemon.c (process_process_fork): Fix argument handling, due to
276 buggy understanding of g_strsplit() behaviour.
278 2002-07-03 Dick Porter <dick@ximian.com>
281 * threads.c: Implement OpenThread(). Define access-control values
287 * Makefile.am: Added access.h, to hold shared access-control
290 2002-07-02 Dick Porter <dick@ximian.com>
292 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
294 2002-07-02 Dick Porter <dick@ximian.com>
296 * handles.c (shared_init): Make a second attempt to contact the
297 daemon if the shared memory attach succeeds, but the connect()
298 fails. (This copes with the daemon crashing without cleaning up
304 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
305 the daemon, it's now built into the library.
307 2002-06-25 Dick Porter <dick@ximian.com>
312 * daemon.c: Process forking and handle data management
316 * processes.c: Process forking and other support functions
318 2002-06-25 Dick Porter <dick@ximian.com>
320 * versioninfo.h: PE resource decoding
322 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
323 to be told the string length
325 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
326 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
329 2002-06-12 Dick Porter <dick@ximian.com>
332 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
333 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
334 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
336 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
338 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
339 when writing to a closed socket.
341 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
343 * mono-mutex.c (mono_once): New convenience function for my
348 * critical-sections.c:
356 * atomic.c: Use mono_once() rather than pthread_once().
358 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
360 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
361 if multiple threads all try to call _wapi_handle_new() before the
362 shared data has been initialized, it is possible that we could get
363 into a condition where shared_init() is being executed and later
364 threads will pass by pthread_once() due to the fact that it has
365 already been called and so therefor will attempt to use the shared
366 data before it has been completely initialized. If we instead use
367 a standard mutex locking mechanism around shared_init(), we can
368 avoid the situation entirely. By wrapping the mutex locking in a
369 check to see if we've already initialized the data, we can even
370 avoid wasting resources by having to lock/unlock the mutex in any
371 later calls (the only time we'd have to worry about
372 locking/unlocking is the initial race to call shared_init() at
375 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
377 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
379 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
381 * daemon.c, handles.c: rename "sun" local var since it's apparently
382 a #define on Solaris.
384 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
386 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
389 2002-05-15 Dick Porter <dick@ximian.com>
391 * wait.c: Fix a deadlock in WaitForMultipleObjects
393 2002-05-14 Dick Porter <dick@ximian.com>
395 * io.c: Fix a cut&paste error, found by
396 Jaroslaw Kowalski <jarek@atm.com.pl>
398 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
402 2002-05-09 Dick Porter <dick@ximian.com>
410 * Makefile.am: Remove now-unused file wait-private.h
412 2002-05-08 Dick Porter <dick@ximian.com>
414 * shared.c: Better error messages, and report when daemon
415 connection fails rather than blocking forever. Do some more
416 shared memory sanity checking.
418 * handles.c: Better error messages when connecting to shared
419 memory and the handle daemon. Fall back to non-shared handles if
420 an error occurs. Set the default back to 'shared handles'. Fix a
421 crashing bug in scratch space allocation that mangled the block
424 2002-05-07 Miguel de Icaza <miguel@ximian.com>
426 * handles.c (shared_init): Disable SHM for now, people have too
427 many problems with this, and the diagnostics are not helping.
429 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
431 * io.c: CreateFile sets win32 last error.
433 2002-05-05 Dick Porter <dick@ximian.com>
444 * semaphore-private.h:
448 * event-private.h: Simplify the WapiHandleOps struct: take out all
449 the file-specific entries, leaving just the items that operate on
450 handles themselves. Split the close operation into shared and
451 private parts: shared close is called by the daemon.
453 * handles.c: As above, but also pass handle allocation, ref and
454 unref operations to the daemon. Populate the handle_ops array at
455 compile time, because the daemon needs to call ops on handles too.
456 Don't bother to track open handle counts any more, the daemon does
460 * thread-private.h: As above, but also make the thread data
463 * shared.c: Fork a handle daemon if the calling process created
464 the shared memory segment.
469 * Makefile.am: Build a daemon to manage handle allocation and
470 destruction without needing to lock the shared memory
472 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
474 * atomic.c: Changed to use a normal mutex rather than a spinlock
475 since a lot of platforms seem to not have them :\
477 2002-04-30 Dick Porter <dick@ximian.com>
479 * Completely rewrote the handle waiting code: removed the helper
480 thread and its attendant complexity. All handle waiting is now
481 abstracted into the WaitForSingleObject() and
482 WaitForMultipleObjects() functions.
484 * Implemented inter-process sharing of handles using sysv shared
485 memory. This makes handles even more opaque, with a handle now
486 just an index into an array.
488 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
490 * io.c: unitialized pointer in GetCurrentDirectory.
492 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
494 * threads.c: destroy the mutex at thread destruction
495 (if/when thread destruction code will be actually called).
496 When protecting a tls data pointer from the gc, use also the
497 thread id in the key.
499 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
501 * timed-thread.c: avoid race condition when setting the thread to
504 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
506 * jit.h: to more #include lines to avoid breaking compilation
507 under windows when upgrading mingw and w32api to version
510 2002-04-16 Dick Porter <dick@ximian.com>
512 * atomic.h: Explanatory comment about lack of 80386 support
514 2002-04-15 Dick Porter <dick@ximian.com>
516 * atomic.h: use xaddl for InterlockedIncrement() and
517 InterlockedDecrement(). Use cmpxchgl in a loop for
518 InterlockedExchange() and InterlockedExchangePointer().
520 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
522 * unicode.c: fix unicode_len() to not access uninitialized memory
523 (and updated to conform to mono code style).
525 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
527 * io.c: EEXISTS is ignored for directory creation.
528 * mono-mutex.h: remove silly "pragma }" that emacs users insert
529 because they use a broken editor:-)
531 2002-03-28 Dick Porter <dick@ximian.com>
537 * handles.c: Warning cleanups
539 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
541 * unicode.h, unicode.c: changed to gunichar2
542 * io.h, io.c: changed strings to gunichar2*, added
543 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
544 some fixes to FindFirstFile() and friends.
546 2002-03-26 Dick Porter <dick@ximian.com>
548 * types.h: Implement the large integer struct

552 QueryPerformanceCounter() and QueryPerformanceFrequency()
555 * threads.c: Implement SleepEx()
558 * system.c: Beginnings of GetSystemInfo()
560 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
564 * context.c: Dummy function that doesnt yet implement
568 * atomic.c: Interlocked functions
570 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
572 * threads.c: use a gc-safe hash table to store tls pointers.
574 2002-03-22 Dick Porter <dick@ximian.com>
576 * threads.c: Fix a race condition where a thread can start and
577 exit before the handle has been properly initialised (no reason
578 why the handle couldn't be initialised beforehand, so do so)
580 Fix a ms to ns conversion magnitude thinko.
582 2002-03-21 Dick Porter <dick@ximian.com>
584 * semaphores.c: Fix a problem when waiting for one or more
585 semaphores, and another semaphore is Released (all waiting
586 semaphores assumed they were signalled)
588 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
590 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
591 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
593 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
595 * threads.c (Sleep): bug fix: 1ms == 1000000ns
597 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
599 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
600 threads.c, io.c: added flush method to handles.
602 * io.c: FlushFileBuffers() and FindFirstFile() functions.
604 Thu Mar 7 17:21:52 CET 2002 Paolo Molaro <lupus@ximian.com>
606 * threads.c, timed-thread.c, wait.c: Boehm-GC anable.

616 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
618 * io-layer.h: conditionally include sys/filio.h and sys/sockio.h
619 for FIONBIO, FIONREAD, and SIOCATMARK.
621 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
623 * sockets.c: conditionally include sys/filio.h and sys/sockio.h
624 for FIONBIO, FIONREAD, and SIOCATMARK.

634 arguments for the sake of portability. Implements recursive
635 mutexes and pthread_mutex_timedlock.
637 * critical-sections.c:
644 * wait.c: Use the mono-mutex wrapper portability functions/macros.
646 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
648 2002-01-23 Dick Porter <dick@ximian.com>
650 * sockets.c: Networking support, mostly wrapping BSD socket APIs
651 with handle code, and translating errno into w32 error codes.
653 * macros.h: Some w32 macros used with the socket support
655 * error.c: Implemented GetLastError() and SetLastError()

668 * io.c: Implement DeleteFile(), GetFileTime(), SetFileTime() and
669 FileTimeToSystemTime().

675 * events.c (event_close): Release the internal pthreads resources
677 2001-11-26 Dick Porter <dick@ximian.com>
