1 2002-10-31 Dick Porter <dick@ximian.com>
4 * io.c: Define and use INVALID_FILE_ATTRIBUTES
6 2002-10-07 Dick Porter <dick@ximian.com>
9 * daemon.c: Use a more accurate time source for process start and
12 2002-10-03 Dick Porter <dick@ximian.com>
16 * threads.c: Fixes for freebsd. Make sure that mutex and condition
17 creation and deletion happen in the process that owns them, when
18 POSIX shared thread objects aren't supported. This breaks on
19 freebsd, as pthread_t is a pointer to data.
21 2002-10-02 Dick Porter <dick@ximian.com>
23 * shared.c: Use mmap() instead of sysv shm for the shared data.
25 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
29 * daemon.c: mmap()ed regions survive fork, so just pass the
30 pointer to _wapi_daemon_main instead of mapping it again.
32 2002-10-01 Dick Porter <dick@ximian.com>
34 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
35 Unfortunately libgc uses the same thread suspend technique that I
36 want to, and the two don't mix: libgc will deadlock when it tries
37 to stop the world if a thread has already been suspended by
38 someone else. Just do the simple suspended create rather than the
39 general purpose thread suspension for now.
41 * threads.c: Pass create flags to the timed_thread create call, to
42 implement suspended thread creation. ResumeThread() partially
43 implemented, to cope with the case where a newly created but
44 suspended thread is launched.
46 2002-09-30 Dick Porter <dick@ximian.com>
48 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
51 2002-09-27 Dick Porter <dick@ximian.com>
53 * semaphores.c: Only include semaphore.h if it's present. Patch
54 for BSD from jmmv@hispabsd.org (Julio Merino).
56 2002-09-27 Dick Porter <dick@ximian.com>
58 * processes.c: Pass environment and working directory to the
59 daemon when forking. Don't let argv[0] be duplicated when looking
60 for the program name. Implement EnumProcessModules (simple
61 version for now, lsof-style later if needed), GetModuleBaseName,
62 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
63 aren't available on Linux).
65 * process-private.h: Store the process name, and the working set
69 * handles-private.h: New functions to store and retrieve an array
70 of strings in the scratch space
72 * daemon.c: Don't miss deleting some handles when a client exits
73 (we used to rely on the client doing the final cleanup, but
74 obviously if the client is no longer there the daemon has to do
77 Process forking now sets the environment and the working
80 * io.c: Don't confuse fd 0 with an unassigned handle struct
82 * atomic.h: Add a google cache alternative to the msdn URL
84 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
87 (_wapi_recvfrom): added ECONNRESET to the switch.
89 2002-09-24 Mark Crichton <crichton@gimp.org>
91 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
94 2002-09-19 Mark Crichton <crichton@gimp.org>
96 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
97 dont have Linux's abstract filesystem for sockets.
99 2002-09-19 Mark Crichton <crichton@gimp.org>
101 * atomic.h: Added SPARC atomic asm code.
102 * daemon.c, handles-private.h, handles.c, wapi-private.h:
103 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
104 Solaris 9, however, the code paths don't seem to work. More testing
105 on the shared case is *really* needed.
107 2002-09-03 Dick Porter <dick@ximian.com>
110 * threads.c: Removed PosixKillThread(), because it's not in the
113 2002-08-20 Dick Porter <dick@ximian.com>
115 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
116 multiples of 4 bytes, to keep header structures aligned. Needed
117 for sparc, at least. (Patch from crichton@gimp.org)
119 * handles.c: Removed 'disable_shm' variable (we've defaulted to
120 building with shm enabled for months now)
122 2002-08-19 Dick Porter <dick@ximian.com>
124 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
125 for legacy NeXT-based systems.
127 2002-08-12 Dick Porter <dick@ximian.com>
129 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
130 from Joseph Wenninger <kde@jowenn.at>)
132 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
134 * threads.c: use fast spinlocks by default
136 2002-08-02 Dick Porter <dick@ximian.com>
138 * io.c (GetStdHandle): Add a handle reference when returning a
139 duplicate console handle. This fixes the unref_handle errors in
142 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
144 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
147 2002-08-01 Dick Porter <dick@ximian.com>
149 * threads.c: Use atomic spinlocks in TLS functions
152 * Makefile.am: Added mono-spinlock.h
154 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
156 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
157 these are needed for sendmsg() and also for struct msghdr (at
158 least on Solaris). Solaris still won't build because struct msghdr
159 doesn't have msg_flags, msg_control, or msg_controllen members.
160 (CMSG_SPACE): Define for systems that don't have it.
163 2002-07-20 Dick Porter <dick@ximian.com>
169 * handles.c: Implemented pipe handles
172 * daemon.c: Fixed bug in handle closing.
175 * daemon.c: Forked processes now close all open file descriptors.
177 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
179 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
182 2002-07-19 Martin Baulig <martin@gnome.org>
184 * threads.c (ExitThread): Call exit() if no threads has been
187 2002-07-17 Dick Porter <dick@ximian.com>
189 * daemon-messages.c: Freebsd fixes from Andreas Kohn
190 <andreas.kohn@gmx.net>
192 2002-07-15 Dick Porter <dick@ximian.com>
194 * io.c: Removed bogus console_flush() method, that was just cut
195 and pasted from file_flush when I separated the two handle types.
197 2002-07-12 Dick Porter <dick@ximian.com>
199 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
200 flags. Fixes bug 27633.
202 2002-07-12 Dick Porter <dick@ximian.com>
206 * daemon.c: Use size of sockaddr_un.sun_path from config.h
208 2002-07-12 Dick Porter <dick@ximian.com>
210 * processes.c (CreateProcess): Send stdin, stdout and stderr
211 handles if the startup info doesnt specify new ones
213 * io.c (GetStdHandle): Return the same handle when the same
214 standard handle is requested
216 * handles.c: Pass file descriptors when forking
218 * daemon.c: Use supplied file descriptors when forking a new
222 * daemon-messages.c: Pass stdin, stdout and stderr file
223 descriptors to the daemon (used when forking)
225 2002-07-11 Miguel de Icaza <miguel@ximian.com>
227 * daemon.c (_wapi_daemon_main): Use sizeof
228 (main_socket_address.sun_path) instead of hardcoded 108 value.
230 * handles.c (shared_init): Use sizeof
231 (shared_socket_address.sun_path) instead of hardcoded 108 value.
233 2002-07-10 Dennis Haney <davh@davh.dk>
237 * daemon.c: Lots of documentation, some added error checking, and
238 code readability improvements.
240 * daemon-messages.h: Add the Error request type to improve error
243 * daemon-messages.c: Do a bit more error checking on send() and
244 recv(), and log errors with a higher severity level.
246 2002-07-04 Dick Porter <dick@ximian.com>
248 * daemon.c (process_process_fork): Fix argument handling, due to
249 buggy understanding of g_strsplit() behaviour.
251 2002-07-03 Dick Porter <dick@ximian.com>
254 * threads.c: Implement OpenThread(). Define access-control values
260 * Makefile.am: Added access.h, to hold shared access-control
263 2002-07-02 Dick Porter <dick@ximian.com>
265 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
267 2002-07-02 Dick Porter <dick@ximian.com>
269 * handles.c (shared_init): Make a second attempt to contact the
270 daemon if the shared memory attach succeeds, but the connect()
271 fails. (This copes with the daemon crashing without cleaning up
277 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
278 the daemon, it's now built into the library.
280 2002-06-25 Dick Porter <dick@ximian.com>
285 * daemon.c: Process forking and handle data management
289 * processes.c: Process forking and other support functions
291 2002-06-25 Dick Porter <dick@ximian.com>
293 * versioninfo.h: PE resource decoding
295 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
296 to be told the string length
298 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
299 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
302 2002-06-12 Dick Porter <dick@ximian.com>
305 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
306 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
307 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
309 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
311 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
312 when writing to a closed socket.
314 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
316 * mono-mutex.c (mono_once): New convenience function for my
321 * critical-sections.c:
329 * atomic.c: Use mono_once() rather than pthread_once().
331 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
333 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
334 if multiple threads all try to call _wapi_handle_new() before the
335 shared data has been initialized, it is possible that we could get
336 into a condition where shared_init() is being executed and later
337 threads will pass by pthread_once() due to the fact that it has
338 already been called and so therefor will attempt to use the shared
339 data before it has been completely initialized. If we instead use
340 a standard mutex locking mechanism around shared_init(), we can
341 avoid the situation entirely. By wrapping the mutex locking in a
342 check to see if we've already initialized the data, we can even
343 avoid wasting resources by having to lock/unlock the mutex in any
344 later calls (the only time we'd have to worry about
345 locking/unlocking is the initial race to call shared_init() at
348 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
350 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
352 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
354 * daemon.c, handles.c: rename "sun" local var since it's apparently
355 a #define on Solaris.
357 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
359 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
362 2002-05-15 Dick Porter <dick@ximian.com>
364 * wait.c: Fix a deadlock in WaitForMultipleObjects
366 2002-05-14 Dick Porter <dick@ximian.com>
368 * io.c: Fix a cut&paste error, found by
369 Jaroslaw Kowalski <jarek@atm.com.pl>
371 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
375 2002-05-09 Dick Porter <dick@ximian.com>
383 * Makefile.am: Remove now-unused file wait-private.h
385 2002-05-08 Dick Porter <dick@ximian.com>
387 * shared.c: Better error messages, and report when daemon
388 connection fails rather than blocking forever. Do some more
389 shared memory sanity checking.
391 * handles.c: Better error messages when connecting to shared
392 memory and the handle daemon. Fall back to non-shared handles if
393 an error occurs. Set the default back to 'shared handles'. Fix a
394 crashing bug in scratch space allocation that mangled the block
397 2002-05-07 Miguel de Icaza <miguel@ximian.com>
399 * handles.c (shared_init): Disable SHM for now, people have too
400 many problems with this, and the diagnostics are not helping.
402 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
404 * io.c: CreateFile sets win32 last error.
406 2002-05-05 Dick Porter <dick@ximian.com>
417 * semaphore-private.h:
421 * event-private.h: Simplify the WapiHandleOps struct: take out all
422 the file-specific entries, leaving just the items that operate on
423 handles themselves. Split the close operation into shared and
424 private parts: shared close is called by the daemon.
426 * handles.c: As above, but also pass handle allocation, ref and
427 unref operations to the daemon. Populate the handle_ops array at
428 compile time, because the daemon needs to call ops on handles too.
429 Don't bother to track open handle counts any more, the daemon does
433 * thread-private.h: As above, but also make the thread data
436 * shared.c: Fork a handle daemon if the calling process created
437 the shared memory segment.
442 * Makefile.am: Build a daemon to manage handle allocation and
443 destruction without needing to lock the shared memory
445 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
447 * atomic.c: Changed to use a normal mutex rather than a spinlock
448 since a lot of platforms seem to not have them :\
450 2002-04-30 Dick Porter <dick@ximian.com>
452 * Completely rewrote the handle waiting code: removed the helper
453 thread and its attendant complexity. All handle waiting is now
454 abstracted into the WaitForSingleObject() and
455 WaitForMultipleObjects() functions.
457 * Implemented inter-process sharing of handles using sysv shared
458 memory. This makes handles even more opaque, with a handle now
459 just an index into an array.
461 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
463 * io.c: unitialized pointer in GetCurrentDirectory.
465 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
467 * threads.c: destroy the mutex at thread destruction
468 (if/when thread destruction code will be actually called).
469 When protecting a tls data pointer from the gc, use also the
470 thread id in the key.
472 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
474 * timed-thread.c: avoid race condition when setting the thread to
477 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
479 * jit.h: to more #include lines to avoid breaking compilation
480 under windows when upgrading mingw and w32api to version
483 2002-04-16 Dick Porter <dick@ximian.com>
485 * atomic.h: Explanatory comment about lack of 80386 support
487 2002-04-15 Dick Porter <dick@ximian.com>
489 * atomic.h: use xaddl for InterlockedIncrement() and
490 InterlockedDecrement(). Use cmpxchgl in a loop for
491 InterlockedExchange() and InterlockedExchangePointer().
493 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
495 * unicode.c: fix unicode_len() to not access uninitialized memory
496 (and updated to conform to mono code style).
498 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
500 * io.c: EEXISTS is ignored for directory creation.
501 * mono-mutex.h: remove silly "pragma }" that emacs users insert
502 because they use a broken editor:-)
504 2002-03-28 Dick Porter <dick@ximian.com>
510 * handles.c: Warning cleanups
512 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
514 * unicode.h, unicode.c: changed to gunichar2
515 * io.h, io.c: changed strings to gunichar2*, added
516 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
517 some fixes to FindFirstFile() and friends.
519 2002-03-26 Dick Porter <dick@ximian.com>
521 * types.h: Implement the large integer struct
524 * timefuncs.c: Dummy functions that don't yet implement
525 QueryPerformanceCounter() and QueryPerformanceFrequency()
528 * threads.c: Implement SleepEx()
531 * system.c: Beginnings of GetSystemInfo()
533 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
537 * context.c: Dummy function that doesnt yet implement
541 * atomic.c: Interlocked functions
543 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
545 * threads.c: use a gc-safe hash table to store tls pointers.
547 2002-03-22 Dick Porter <dick@ximian.com>
549 * threads.c: Fix a race condition where a thread can start and
550 exit before the handle has been properly initialised (no reason
551 why the handle couldn't be initialised beforehand, so do so)
553 Fix a ms to ns conversion magnitude thinko.
555 2002-03-21 Dick Porter <dick@ximian.com>
557 * semaphores.c: Fix a problem when waiting for one or more
558 semaphores, and another semaphore is Released (all waiting
559 semaphores assumed they were signalled)
561 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
563 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
564 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
566 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
568 * threads.c (Sleep): bug fix: 1ms == 1000000ns
570 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
572 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
573 threads.c, io.c: added flush method to handles.
575 * io.c: FlushFileBuffers() and FindFirstFile() functions.
577 Thu Mar 7 17:21:52 CET 2002 Paolo Molaro <lupus@ximian.com>
579 * threads.c, timed-thread.c, wait.c: Boehm-GC anable.

589 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
591 * io-layer.h: conditionally include sys/filio.h and sys/sockio.h
592 for FIONBIO, FIONREAD, and SIOCATMARK.
594 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
596 * sockets.c: conditionally include sys/filio.h and sys/sockio.h
597 for FIONBIO, FIONREAD, and SIOCATMARK.

607 arguments for the sake of portability. Implements recursive
608 mutexes and pthread_mutex_timedlock.
610 * critical-sections.c:
617 * wait.c: Use the mono-mutex wrapper portability functions/macros.
619 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
621 2002-01-23 Dick Porter <dick@ximian.com>
623 * sockets.c: Networking support, mostly wrapping BSD socket APIs
624 with handle code, and translating errno into w32 error codes.
626 * macros.h: Some w32 macros used with the socket support
628 * error.c: Implemented GetLastError() and SetLastError()

720 (from Nick Drochak <ndrochak@gol.com>)
722 2001-11-10 Dick Porter <dick@ximian.com>

730 * pthread-compat.c: added some include files to make it compile on
733 2001-11-08 Dick Porter <dick@ximian.com>
737 This is a library emulating the win32 threading and IO API.
