1 2002-11-15 Dick Porter <dick@ximian.com>
3 * timed-thread.c: Removed unneeded parameters in
4 _wapi_timed_thread_attach().
6 * threads.c: Renamed AttachThread() to make it not look like
7 external API. Removed unneeded parameters.
9 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
11 * error.[ch]: added errno_to_WSA (). It displays a warning and return
12 WSASYSCALLFAILURE if there is no error mapping for the given errno,
14 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
16 2002-10-31 Dick Porter <dick@ximian.com>
19 * io.c: Define and use INVALID_FILE_ATTRIBUTES
21 2002-10-07 Dick Porter <dick@ximian.com>
24 * daemon.c: Use a more accurate time source for process start and
27 2002-10-03 Dick Porter <dick@ximian.com>
31 * threads.c: Fixes for freebsd. Make sure that mutex and condition
32 creation and deletion happen in the process that owns them, when
33 POSIX shared thread objects aren't supported. This breaks on
34 freebsd, as pthread_t is a pointer to data.
36 2002-10-02 Dick Porter <dick@ximian.com>
38 * shared.c: Use mmap() instead of sysv shm for the shared data.
40 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
44 * daemon.c: mmap()ed regions survive fork, so just pass the
45 pointer to _wapi_daemon_main instead of mapping it again.
47 2002-10-01 Dick Porter <dick@ximian.com>
49 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
50 Unfortunately libgc uses the same thread suspend technique that I
51 want to, and the two don't mix: libgc will deadlock when it tries
52 to stop the world if a thread has already been suspended by
53 someone else. Just do the simple suspended create rather than the
54 general purpose thread suspension for now.
56 * threads.c: Pass create flags to the timed_thread create call, to
57 implement suspended thread creation. ResumeThread() partially
58 implemented, to cope with the case where a newly created but
59 suspended thread is launched.
61 2002-09-30 Dick Porter <dick@ximian.com>
63 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
66 2002-09-27 Dick Porter <dick@ximian.com>
68 * semaphores.c: Only include semaphore.h if it's present. Patch
69 for BSD from jmmv@hispabsd.org (Julio Merino).
71 2002-09-27 Dick Porter <dick@ximian.com>
73 * processes.c: Pass environment and working directory to the
74 daemon when forking. Don't let argv[0] be duplicated when looking
75 for the program name. Implement EnumProcessModules (simple
76 version for now, lsof-style later if needed), GetModuleBaseName,
77 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
78 aren't available on Linux).
80 * process-private.h: Store the process name, and the working set
84 * handles-private.h: New functions to store and retrieve an array
85 of strings in the scratch space
87 * daemon.c: Don't miss deleting some handles when a client exits
88 (we used to rely on the client doing the final cleanup, but
89 obviously if the client is no longer there the daemon has to do
92 Process forking now sets the environment and the working
95 * io.c: Don't confuse fd 0 with an unassigned handle struct
97 * atomic.h: Add a google cache alternative to the msdn URL
99 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
102 (_wapi_recvfrom): added ECONNRESET to the switch.
104 2002-09-24 Mark Crichton <crichton@gimp.org>
106 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
109 2002-09-19 Mark Crichton <crichton@gimp.org>
111 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
112 dont have Linux's abstract filesystem for sockets.
114 2002-09-19 Mark Crichton <crichton@gimp.org>
116 * atomic.h: Added SPARC atomic asm code.
117 * daemon.c, handles-private.h, handles.c, wapi-private.h:
118 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
119 Solaris 9, however, the code paths don't seem to work. More testing
120 on the shared case is *really* needed.
122 2002-09-03 Dick Porter <dick@ximian.com>
125 * threads.c: Removed PosixKillThread(), because it's not in the
128 2002-08-20 Dick Porter <dick@ximian.com>
130 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
131 multiples of 4 bytes, to keep header structures aligned. Needed
132 for sparc, at least. (Patch from crichton@gimp.org)
134 * handles.c: Removed 'disable_shm' variable (we've defaulted to
135 building with shm enabled for months now)
137 2002-08-19 Dick Porter <dick@ximian.com>
139 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
140 for legacy NeXT-based systems.
142 2002-08-12 Dick Porter <dick@ximian.com>
144 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
145 from Joseph Wenninger <kde@jowenn.at>)
147 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
149 * threads.c: use fast spinlocks by default
151 2002-08-02 Dick Porter <dick@ximian.com>
153 * io.c (GetStdHandle): Add a handle reference when returning a
154 duplicate console handle. This fixes the unref_handle errors in
157 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
159 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
162 2002-08-01 Dick Porter <dick@ximian.com>
164 * threads.c: Use atomic spinlocks in TLS functions
167 * Makefile.am: Added mono-spinlock.h
169 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
171 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
172 these are needed for sendmsg() and also for struct msghdr (at
173 least on Solaris). Solaris still won't build because struct msghdr
174 doesn't have msg_flags, msg_control, or msg_controllen members.
175 (CMSG_SPACE): Define for systems that don't have it.
178 2002-07-20 Dick Porter <dick@ximian.com>
184 * handles.c: Implemented pipe handles
187 * daemon.c: Fixed bug in handle closing.
190 * daemon.c: Forked processes now close all open file descriptors.
192 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
194 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
197 2002-07-19 Martin Baulig <martin@gnome.org>
199 * threads.c (ExitThread): Call exit() if no threads has been
202 2002-07-17 Dick Porter <dick@ximian.com>
204 * daemon-messages.c: Freebsd fixes from Andreas Kohn
205 <andreas.kohn@gmx.net>
207 2002-07-15 Dick Porter <dick@ximian.com>
209 * io.c: Removed bogus console_flush() method, that was just cut
210 and pasted from file_flush when I separated the two handle types.
212 2002-07-12 Dick Porter <dick@ximian.com>
214 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
215 flags. Fixes bug 27633.
217 2002-07-12 Dick Porter <dick@ximian.com>
221 * daemon.c: Use size of sockaddr_un.sun_path from config.h
223 2002-07-12 Dick Porter <dick@ximian.com>
225 * processes.c (CreateProcess): Send stdin, stdout and stderr
226 handles if the startup info doesnt specify new ones
228 * io.c (GetStdHandle): Return the same handle when the same
229 standard handle is requested
231 * handles.c: Pass file descriptors when forking
233 * daemon.c: Use supplied file descriptors when forking a new
237 * daemon-messages.c: Pass stdin, stdout and stderr file
238 descriptors to the daemon (used when forking)
240 2002-07-11 Miguel de Icaza <miguel@ximian.com>
242 * daemon.c (_wapi_daemon_main): Use sizeof
243 (main_socket_address.sun_path) instead of hardcoded 108 value.
245 * handles.c (shared_init): Use sizeof
246 (shared_socket_address.sun_path) instead of hardcoded 108 value.
248 2002-07-10 Dennis Haney <davh@davh.dk>
252 * daemon.c: Lots of documentation, some added error checking, and
253 code readability improvements.
255 * daemon-messages.h: Add the Error request type to improve error
258 * daemon-messages.c: Do a bit more error checking on send() and
259 recv(), and log errors with a higher severity level.
261 2002-07-04 Dick Porter <dick@ximian.com>
263 * daemon.c (process_process_fork): Fix argument handling, due to
264 buggy understanding of g_strsplit() behaviour.
266 2002-07-03 Dick Porter <dick@ximian.com>
269 * threads.c: Implement OpenThread(). Define access-control values
275 * Makefile.am: Added access.h, to hold shared access-control
278 2002-07-02 Dick Porter <dick@ximian.com>
280 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
282 2002-07-02 Dick Porter <dick@ximian.com>
284 * handles.c (shared_init): Make a second attempt to contact the
285 daemon if the shared memory attach succeeds, but the connect()
286 fails. (This copes with the daemon crashing without cleaning up
292 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
293 the daemon, it's now built into the library.
295 2002-06-25 Dick Porter <dick@ximian.com>
300 * daemon.c: Process forking and handle data management
304 * processes.c: Process forking and other support functions
306 2002-06-25 Dick Porter <dick@ximian.com>
308 * versioninfo.h: PE resource decoding
310 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
311 to be told the string length
313 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
314 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
317 2002-06-12 Dick Porter <dick@ximian.com>
320 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
321 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
322 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
324 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
326 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
327 when writing to a closed socket.
329 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
331 * mono-mutex.c (mono_once): New convenience function for my
336 * critical-sections.c:
344 * atomic.c: Use mono_once() rather than pthread_once().
346 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
348 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
349 if multiple threads all try to call _wapi_handle_new() before the
350 shared data has been initialized, it is possible that we could get
351 into a condition where shared_init() is being executed and later
352 threads will pass by pthread_once() due to the fact that it has
353 already been called and so therefor will attempt to use the shared
354 data before it has been completely initialized. If we instead use
355 a standard mutex locking mechanism around shared_init(), we can
356 avoid the situation entirely. By wrapping the mutex locking in a
357 check to see if we've already initialized the data, we can even
358 avoid wasting resources by having to lock/unlock the mutex in any
359 later calls (the only time we'd have to worry about
360 locking/unlocking is the initial race to call shared_init() at
363 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
365 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
367 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
369 * daemon.c, handles.c: rename "sun" local var since it's apparently
370 a #define on Solaris.
372 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
374 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
377 2002-05-15 Dick Porter <dick@ximian.com>
379 * wait.c: Fix a deadlock in WaitForMultipleObjects
381 2002-05-14 Dick Porter <dick@ximian.com>
383 * io.c: Fix a cut&paste error, found by
384 Jaroslaw Kowalski <jarek@atm.com.pl>
386 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
390 2002-05-09 Dick Porter <dick@ximian.com>
398 * Makefile.am: Remove now-unused file wait-private.h
400 2002-05-08 Dick Porter <dick@ximian.com>
402 * shared.c: Better error messages, and report when daemon
403 connection fails rather than blocking forever. Do some more
404 shared memory sanity checking.
406 * handles.c: Better error messages when connecting to shared
407 memory and the handle daemon. Fall back to non-shared handles if
408 an error occurs. Set the default back to 'shared handles'. Fix a
409 crashing bug in scratch space allocation that mangled the block
412 2002-05-07 Miguel de Icaza <miguel@ximian.com>
414 * handles.c (shared_init): Disable SHM for now, people have too
415 many problems with this, and the diagnostics are not helping.
417 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
419 * io.c: CreateFile sets win32 last error.
421 2002-05-05 Dick Porter <dick@ximian.com>
432 * semaphore-private.h:
436 * event-private.h: Simplify the WapiHandleOps struct: take out all
437 the file-specific entries, leaving just the items that operate on
438 handles themselves. Split the close operation into shared and
439 private parts: shared close is called by the daemon.
441 * handles.c: As above, but also pass handle allocation, ref and
442 unref operations to the daemon. Populate the handle_ops array at
443 compile time, because the daemon needs to call ops on handles too.
444 Don't bother to track open handle counts any more, the daemon does
448 * thread-private.h: As above, but also make the thread data
451 * shared.c: Fork a handle daemon if the calling process created
452 the shared memory segment.
457 * Makefile.am: Build a daemon to manage handle allocation and
458 destruction without needing to lock the shared memory
460 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
462 * atomic.c: Changed to use a normal mutex rather than a spinlock
463 since a lot of platforms seem to not have them :\
465 2002-04-30 Dick Porter <dick@ximian.com>
467 * Completely rewrote the handle waiting code: removed the helper
468 thread and its attendant complexity. All handle waiting is now
469 abstracted into the WaitForSingleObject() and
470 WaitForMultipleObjects() functions.
472 * Implemented inter-process sharing of handles using sysv shared
473 memory. This makes handles even more opaque, with a handle now
474 just an index into an array.
476 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
478 * io.c: unitialized pointer in GetCurrentDirectory.
480 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
482 * threads.c: destroy the mutex at thread destruction
483 (if/when thread destruction code will be actually called).
484 When protecting a tls data pointer from the gc, use also the
485 thread id in the key.
487 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
489 * timed-thread.c: avoid race condition when setting the thread to
492 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
494 * jit.h: to more #include lines to avoid breaking compilation
495 under windows when upgrading mingw and w32api to version
498 2002-04-16 Dick Porter <dick@ximian.com>
500 * atomic.h: Explanatory comment about lack of 80386 support
502 2002-04-15 Dick Porter <dick@ximian.com>
504 * atomic.h: use xaddl for InterlockedIncrement() and
505 InterlockedDecrement(). Use cmpxchgl in a loop for
506 InterlockedExchange() and InterlockedExchangePointer().
508 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
510 * unicode.c: fix unicode_len() to not access uninitialized memory
511 (and updated to conform to mono code style).
513 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
515 * io.c: EEXISTS is ignored for directory creation.
516 * mono-mutex.h: remove silly "pragma }" that emacs users insert
517 because they use a broken editor:-)
519 2002-03-28 Dick Porter <dick@ximian.com>
525 * handles.c: Warning cleanups
527 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
529 * unicode.h, unicode.c: changed to gunichar2
530 * io.h, io.c: changed strings to gunichar2*, added
531 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
532 some fixes to FindFirstFile() and friends.
534 2002-03-26 Dick Porter <dick@ximian.com>
536 * types.h: Implement the large integer struct
539 * timefuncs.c: Dummy functions that don't yet implement
540 QueryPerformanceCounter() and QueryPerformanceFrequency()
543 * threads.c: Implement SleepEx()
546 * system.c: Beginnings of GetSystemInfo()
548 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
552 * context.c: Dummy function that doesnt yet implement
556 * atomic.c: Interlocked functions
558 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
560 * threads.c: use a gc-safe hash table to store tls pointers.
562 2002-03-22 Dick Porter <dick@ximian.com>
564 * threads.c: Fix a race condition where a thread can start and
565 exit before the handle has been properly initialised (no reason
566 why the handle couldn't be initialised beforehand, so do so)
568 Fix a ms to ns conversion magnitude thinko.
570 2002-03-21 Dick Porter <dick@ximian.com>
572 * semaphores.c: Fix a problem when waiting for one or more
573 semaphores, and another semaphore is Released (all waiting
574 semaphores assumed they were signalled)
576 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
578 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
579 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
581 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
583 * threads.c (Sleep): bug fix: 1ms == 1000000ns
585 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
587 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
588 threads.c, io.c: added flush method to handles.
590 * io.c: FlushFileBuffers() and FindFirstFile() functions.
592 Thu Mar 7 17:21:52 CET 2002 Paolo Molaro <lupus@ximian.com>
594 * threads.c, timed-thread.c, wait.c: Boehm-GC anable.

606 * io-layer.h: conditionally include sys/filio.h and sys/sockio.h
607 for FIONBIO, FIONREAD, and SIOCATMARK.
609 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
611 * sockets.c: conditionally include sys/filio.h and sys/sockio.h

622 arguments for the sake of portability. Implements recursive
623 mutexes and pthread_mutex_timedlock.
625 * critical-sections.c:
632 * wait.c: Use the mono-mutex wrapper portability functions/macros.
634 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
636 2002-01-23 Dick Porter <dick@ximian.com>
638 * sockets.c: Networking support, mostly wrapping BSD socket APIs
639 with handle code, and translating errno into w32 error codes.

656 * io.c: Implement DeleteFile(), GetFileTime(), SetFileTime() and
657 FileTimeToSystemTime().
