1 2003-01-08 Dick Porter <dick@ximian.com>
3 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
5 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
7 * daemon.c, handles-private.h, handles.c, wapi-private.h:
8 Check for an implementation which says it supports
9 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
10 defines the symbol. Defined but with a value of -1 still
11 means that it is unsupported.
13 2002-12-08 Martin Baulig <martin@ximian.com>
15 * handles.c (_wapi_handle_new): Create new non-shared handles with
16 an initial refcount of 1, not 0.
18 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
20 * threads.c (TlsGetValue): removed unnecessary mutex
22 2002-11-20 Dick Porter <dick@ximian.com>
24 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
25 need to store their data structure too.
27 * threads.c: Make sure the threading data is initialised wherever
30 2002-11-15 Dick Porter <dick@ximian.com>
32 * timed-thread.c: Removed unneeded parameters in
33 _wapi_timed_thread_attach().
35 * threads.c: Renamed AttachThread() to make it not look like
36 external API. Removed unneeded parameters.
38 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
40 * error.[ch]: added errno_to_WSA (). It displays a warning and return
41 WSASYSCALLFAILURE if there is no error mapping for the given errno,
43 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
45 2002-10-31 Dick Porter <dick@ximian.com>
48 * io.c: Define and use INVALID_FILE_ATTRIBUTES
50 2002-10-07 Dick Porter <dick@ximian.com>
53 * daemon.c: Use a more accurate time source for process start and
56 2002-10-03 Dick Porter <dick@ximian.com>
60 * threads.c: Fixes for freebsd. Make sure that mutex and condition
61 creation and deletion happen in the process that owns them, when
62 POSIX shared thread objects aren't supported. This breaks on
63 freebsd, as pthread_t is a pointer to data.
65 2002-10-02 Dick Porter <dick@ximian.com>
67 * shared.c: Use mmap() instead of sysv shm for the shared data.
69 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
73 * daemon.c: mmap()ed regions survive fork, so just pass the
74 pointer to _wapi_daemon_main instead of mapping it again.
76 2002-10-01 Dick Porter <dick@ximian.com>
78 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
79 Unfortunately libgc uses the same thread suspend technique that I
80 want to, and the two don't mix: libgc will deadlock when it tries
81 to stop the world if a thread has already been suspended by
82 someone else. Just do the simple suspended create rather than the
83 general purpose thread suspension for now.
85 * threads.c: Pass create flags to the timed_thread create call, to
86 implement suspended thread creation. ResumeThread() partially
87 implemented, to cope with the case where a newly created but
88 suspended thread is launched.
90 2002-09-30 Dick Porter <dick@ximian.com>
92 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
95 2002-09-27 Dick Porter <dick@ximian.com>
97 * semaphores.c: Only include semaphore.h if it's present. Patch
98 for BSD from jmmv@hispabsd.org (Julio Merino).
100 2002-09-27 Dick Porter <dick@ximian.com>
102 * processes.c: Pass environment and working directory to the
103 daemon when forking. Don't let argv[0] be duplicated when looking
104 for the program name. Implement EnumProcessModules (simple
105 version for now, lsof-style later if needed), GetModuleBaseName,
106 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
107 aren't available on Linux).
109 * process-private.h: Store the process name, and the working set
113 * handles-private.h: New functions to store and retrieve an array
114 of strings in the scratch space
116 * daemon.c: Don't miss deleting some handles when a client exits
117 (we used to rely on the client doing the final cleanup, but
118 obviously if the client is no longer there the daemon has to do
121 Process forking now sets the environment and the working
124 * io.c: Don't confuse fd 0 with an unassigned handle struct
126 * atomic.h: Add a google cache alternative to the msdn URL
128 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
131 (_wapi_recvfrom): added ECONNRESET to the switch.
133 2002-09-24 Mark Crichton <crichton@gimp.org>
135 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
138 2002-09-19 Mark Crichton <crichton@gimp.org>
140 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
141 dont have Linux's abstract filesystem for sockets.
143 2002-09-19 Mark Crichton <crichton@gimp.org>
145 * atomic.h: Added SPARC atomic asm code.
146 * daemon.c, handles-private.h, handles.c, wapi-private.h:
147 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
148 Solaris 9, however, the code paths don't seem to work. More testing
149 on the shared case is *really* needed.
151 2002-09-03 Dick Porter <dick@ximian.com>
154 * threads.c: Removed PosixKillThread(), because it's not in the
157 2002-08-20 Dick Porter <dick@ximian.com>
159 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
160 multiples of 4 bytes, to keep header structures aligned. Needed
161 for sparc, at least. (Patch from crichton@gimp.org)
163 * handles.c: Removed 'disable_shm' variable (we've defaulted to
164 building with shm enabled for months now)
166 2002-08-19 Dick Porter <dick@ximian.com>
168 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
169 for legacy NeXT-based systems.
171 2002-08-12 Dick Porter <dick@ximian.com>
173 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
174 from Joseph Wenninger <kde@jowenn.at>)
176 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
178 * threads.c: use fast spinlocks by default
180 2002-08-02 Dick Porter <dick@ximian.com>
182 * io.c (GetStdHandle): Add a handle reference when returning a
183 duplicate console handle. This fixes the unref_handle errors in
186 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
188 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
191 2002-08-01 Dick Porter <dick@ximian.com>
193 * threads.c: Use atomic spinlocks in TLS functions
196 * Makefile.am: Added mono-spinlock.h
198 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
200 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
201 these are needed for sendmsg() and also for struct msghdr (at
202 least on Solaris). Solaris still won't build because struct msghdr
203 doesn't have msg_flags, msg_control, or msg_controllen members.
204 (CMSG_SPACE): Define for systems that don't have it.
207 2002-07-20 Dick Porter <dick@ximian.com>
213 * handles.c: Implemented pipe handles
216 * daemon.c: Fixed bug in handle closing.
219 * daemon.c: Forked processes now close all open file descriptors.
221 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
223 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
226 2002-07-19 Martin Baulig <martin@gnome.org>
228 * threads.c (ExitThread): Call exit() if no threads has been
231 2002-07-17 Dick Porter <dick@ximian.com>
233 * daemon-messages.c: Freebsd fixes from Andreas Kohn
234 <andreas.kohn@gmx.net>
236 2002-07-15 Dick Porter <dick@ximian.com>
238 * io.c: Removed bogus console_flush() method, that was just cut
239 and pasted from file_flush when I separated the two handle types.
241 2002-07-12 Dick Porter <dick@ximian.com>
243 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
244 flags. Fixes bug 27633.
246 2002-07-12 Dick Porter <dick@ximian.com>
250 * daemon.c: Use size of sockaddr_un.sun_path from config.h
252 2002-07-12 Dick Porter <dick@ximian.com>
254 * processes.c (CreateProcess): Send stdin, stdout and stderr
255 handles if the startup info doesnt specify new ones
257 * io.c (GetStdHandle): Return the same handle when the same
258 standard handle is requested
260 * handles.c: Pass file descriptors when forking
262 * daemon.c: Use supplied file descriptors when forking a new
266 * daemon-messages.c: Pass stdin, stdout and stderr file
267 descriptors to the daemon (used when forking)
269 2002-07-11 Miguel de Icaza <miguel@ximian.com>
271 * daemon.c (_wapi_daemon_main): Use sizeof
272 (main_socket_address.sun_path) instead of hardcoded 108 value.
274 * handles.c (shared_init): Use sizeof
275 (shared_socket_address.sun_path) instead of hardcoded 108 value.
277 2002-07-10 Dennis Haney <davh@davh.dk>
281 * daemon.c: Lots of documentation, some added error checking, and
282 code readability improvements.
284 * daemon-messages.h: Add the Error request type to improve error
287 * daemon-messages.c: Do a bit more error checking on send() and
288 recv(), and log errors with a higher severity level.
290 2002-07-04 Dick Porter <dick@ximian.com>
292 * daemon.c (process_process_fork): Fix argument handling, due to
293 buggy understanding of g_strsplit() behaviour.
295 2002-07-03 Dick Porter <dick@ximian.com>
298 * threads.c: Implement OpenThread(). Define access-control values
304 * Makefile.am: Added access.h, to hold shared access-control
307 2002-07-02 Dick Porter <dick@ximian.com>
309 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
311 2002-07-02 Dick Porter <dick@ximian.com>
313 * handles.c (shared_init): Make a second attempt to contact the
314 daemon if the shared memory attach succeeds, but the connect()
315 fails. (This copes with the daemon crashing without cleaning up
321 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
322 the daemon, it's now built into the library.
324 2002-06-25 Dick Porter <dick@ximian.com>
329 * daemon.c: Process forking and handle data management
333 * processes.c: Process forking and other support functions
335 2002-06-25 Dick Porter <dick@ximian.com>
337 * versioninfo.h: PE resource decoding
339 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
340 to be told the string length
342 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
343 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
346 2002-06-12 Dick Porter <dick@ximian.com>
349 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
350 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
351 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
353 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
355 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
356 when writing to a closed socket.
358 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
360 * mono-mutex.c (mono_once): New convenience function for my
365 * critical-sections.c:
373 * atomic.c: Use mono_once() rather than pthread_once().
375 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
377 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
378 if multiple threads all try to call _wapi_handle_new() before the
379 shared data has been initialized, it is possible that we could get
380 into a condition where shared_init() is being executed and later
381 threads will pass by pthread_once() due to the fact that it has
382 already been called and so therefor will attempt to use the shared
383 data before it has been completely initialized. If we instead use
384 a standard mutex locking mechanism around shared_init(), we can
385 avoid the situation entirely. By wrapping the mutex locking in a
386 check to see if we've already initialized the data, we can even
387 avoid wasting resources by having to lock/unlock the mutex in any
388 later calls (the only time we'd have to worry about
389 locking/unlocking is the initial race to call shared_init() at
392 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
394 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
396 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
398 * daemon.c, handles.c: rename "sun" local var since it's apparently
399 a #define on Solaris.
401 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
403 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
406 2002-05-15 Dick Porter <dick@ximian.com>
408 * wait.c: Fix a deadlock in WaitForMultipleObjects
410 2002-05-14 Dick Porter <dick@ximian.com>
412 * io.c: Fix a cut&paste error, found by
413 Jaroslaw Kowalski <jarek@atm.com.pl>
415 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
419 2002-05-09 Dick Porter <dick@ximian.com>
427 * Makefile.am: Remove now-unused file wait-private.h
429 2002-05-08 Dick Porter <dick@ximian.com>
431 * shared.c: Better error messages, and report when daemon
432 connection fails rather than blocking forever. Do some more
433 shared memory sanity checking.
435 * handles.c: Better error messages when connecting to shared
436 memory and the handle daemon. Fall back to non-shared handles if
437 an error occurs. Set the default back to 'shared handles'. Fix a
438 crashing bug in scratch space allocation that mangled the block
441 2002-05-07 Miguel de Icaza <miguel@ximian.com>
443 * handles.c (shared_init): Disable SHM for now, people have too
444 many problems with this, and the diagnostics are not helping.
446 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
448 * io.c: CreateFile sets win32 last error.
450 2002-05-05 Dick Porter <dick@ximian.com>
461 * semaphore-private.h:
465 * event-private.h: Simplify the WapiHandleOps struct: take out all
466 the file-specific entries, leaving just the items that operate on
467 handles themselves. Split the close operation into shared and
468 private parts: shared close is called by the daemon.
470 * handles.c: As above, but also pass handle allocation, ref and
471 unref operations to the daemon. Populate the handle_ops array at
472 compile time, because the daemon needs to call ops on handles too.
473 Don't bother to track open handle counts any more, the daemon does
477 * thread-private.h: As above, but also make the thread data
480 * shared.c: Fork a handle daemon if the calling process created
481 the shared memory segment.
486 * Makefile.am: Build a daemon to manage handle allocation and
487 destruction without needing to lock the shared memory
489 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
491 * atomic.c: Changed to use a normal mutex rather than a spinlock
492 since a lot of platforms seem to not have them :\
494 2002-04-30 Dick Porter <dick@ximian.com>
496 * Completely rewrote the handle waiting code: removed the helper
497 thread and its attendant complexity. All handle waiting is now
498 abstracted into the WaitForSingleObject() and
499 WaitForMultipleObjects() functions.
501 * Implemented inter-process sharing of handles using sysv shared
502 memory. This makes handles even more opaque, with a handle now
503 just an index into an array.
505 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
507 * io.c: unitialized pointer in GetCurrentDirectory.
509 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
511 * threads.c: destroy the mutex at thread destruction
512 (if/when thread destruction code will be actually called).
513 When protecting a tls data pointer from the gc, use also the
514 thread id in the key.
516 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
518 * timed-thread.c: avoid race condition when setting the thread to
521 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
523 * jit.h: to more #include lines to avoid breaking compilation
524 under windows when upgrading mingw and w32api to version
527 2002-04-16 Dick Porter <dick@ximian.com>
529 * atomic.h: Explanatory comment about lack of 80386 support
531 2002-04-15 Dick Porter <dick@ximian.com>
533 * atomic.h: use xaddl for InterlockedIncrement() and
534 InterlockedDecrement(). Use cmpxchgl in a loop for
535 InterlockedExchange() and InterlockedExchangePointer().
537 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
539 * unicode.c: fix unicode_len() to not access uninitialized memory
540 (and updated to conform to mono code style).
542 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
544 * io.c: EEXISTS is ignored for directory creation.
545 * mono-mutex.h: remove silly "pragma }" that emacs users insert
546 because they use a broken editor:-)
548 2002-03-28 Dick Porter <dick@ximian.com>
554 * handles.c: Warning cleanups
556 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
558 * unicode.h, unicode.c: changed to gunichar2
559 * io.h, io.c: changed strings to gunichar2*, added
560 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
561 some fixes to FindFirstFile() and friends.
563 2002-03-26 Dick Porter <dick@ximian.com>
565 * types.h: Implement the large integer struct
568 * timefuncs.c: Dummy functions that don't yet implement
569 QueryPerformanceCounter() and QueryPerformanceFrequency()
572 * threads.c: Implement SleepEx()
575 * system.c: Beginnings of GetSystemInfo()
577 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
581 * context.c: Dummy function that doesnt yet implement
585 * atomic.c: Interlocked functions
587 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
589 * threads.c: use a gc-safe hash table to store tls pointers.
591 2002-03-22 Dick Porter <dick@ximian.com>
593 * threads.c: Fix a race condition where a thread can start and
594 exit before the handle has been properly initialised (no reason
595 why the handle couldn't be initialised beforehand, so do so)
597 Fix a ms to ns conversion magnitude thinko.
599 2002-03-21 Dick Porter <dick@ximian.com>
601 * semaphores.c: Fix a problem when waiting for one or more
602 semaphores, and another semaphore is Released (all waiting
603 semaphores assumed they were signalled)
605 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
607 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
608 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
610 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
612 * threads.c (Sleep): bug fix: 1ms == 1000000ns
614 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
616 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
617 threads.c, io.c: added flush method to handles.
619 * io.c: FlushFileBuffers() and FindFirstFile() functions.
621 Thu Mar 7 17:21:52 CET 2002 Paolo Molaro <lupus@ximian.com>
623 * threads.c, timed-thread.c, wait.c: Boehm-GC anable.

633 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
635 * io-layer.h: conditionally include sys/filio.h and sys/sockio.h
636 for FIONBIO, FIONREAD, and SIOCATMARK.
638 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
640 * sockets.c: conditionally include sys/filio.h and sys/sockio.h
641 for FIONBIO, FIONREAD, and SIOCATMARK.

645 * sockets.c: Implement shutdown and select
647 2002-02-13 Jeffrey Stedfast <fejj@ximian.com>
649 * mono-mutex.[c,h]: New source files that thinly wrap all pthread
650 functions that take pthread_mutex_t and/or pthread_mutexattr_t
651 arguments for the sake of portability. Implements recursive
652 mutexes and pthread_mutex_timedlock.
654 * critical-sections.c:
661 * wait.c: Use the mono-mutex wrapper portability functions/macros.
663 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
665 2002-01-23 Dick Porter <dick@ximian.com>
667 * sockets.c: Networking support, mostly wrapping BSD socket APIs
668 with handle code, and translating errno into w32 error codes.
670 * macros.h: Some w32 macros used with the socket support
672 * error.c: Implemented GetLastError() and SetLastError()
674 * Makefile.am: Added sockets, with kludge to override some symbols
676 2001-12-17 Dietmar Maurer <dietmar@ximian.com>
678 * unicode.c (_wapi_unicode_to_utf8): byteswap UTF16 strings before
679 passing them to iconv
680 (_wapi_unicode_to_utf8): only swap bytes on LE systems, remove bug
681 from previous commit.
683 2001-12-11 Dick Porter <dick@ximian.com>
685 * io.c: Implement DeleteFile(), GetFileTime(), SetFileTime() and
686 FileTimeToSystemTime().
688 * unicode.c (unicode_len): Nasty way of finding length of unicode
689 string with embedded NULLs (counts until two NULLs together).

692 * events.c (event_close): Release the internal pthreads resources
694 2001-11-26 Dick Porter <dick@ximian.com>
