1 2007-08-02 Dick Porter <dick@ximian.com>
3 * sockets.c: Changes in error handling, and move the SO_REUSEADDR
4 setting from metadata/socket-io.c.
6 2007-08-01 Dick Porter <dick@ximian.com>
8 * io-portability.c (_wapi_io_scandir): Special-case patterns
9 ending in '.*' so that files with no extension are also matched.
13 * wapi_glob.c: Reinstate WAPI_GLOB_APPEND, and add
14 WAPI_GLOB_UNIQUE to avoid matching the same entry twice when
17 2007-07-26 Dick Porter <dick@ximian.com>
22 * critical-sections.c:
24 * critical-section-private.h:
27 * error.c: Clean up TLS and pthreads structures. Finishes off bug
30 * collection.c (collection_thread): Exit the collection thread if
31 the io-layer has been cleaned up.
33 * mono-mutex.h (mono_mutexattr_destroy): Add this define too
35 Mon Jul 23 10:40:35 CEST 2007 Paolo Molaro <lupus@ximian.com>
37 * timefuncs.c: make TickCount measure from boot time if it's
40 2007-07-19 Juraj Skripsky <js@hotfeet.ch>
42 * io.c (MoveFile): Fix a leak.
44 Fri Jul 13 12:46:15 CEST 2007 Paolo Molaro <lupus@ximian.com>
46 * handles-private.h, handles.c, thread-private.h, threads.c,
47 uglify.h, wait.c: temporarily revert the alertable wait changes
48 (r79386) until the deadlock issues are fixed.
50 2007-06-22 Dick Porter <dick@ximian.com>
52 * shared.c: The non-shared mutexes weren't being initialised properly
53 on macos. Fixes bug 81929.
55 2007-06-13 Randolph Chung <tausq@debian.org>
57 * atomic.h: Enable for all hppa targets.
58 * Makefile.am: rename hppa_atomic.s to hppa_atomic.S so the preprocessor
60 * hppa_atomic.s: Renamed to ...
61 * hppa_atomic.S: ... and updated to work on both HPUX and Linux.
63 2007-06-13 Dick Porter <dick@ximian.com>
65 * handles.c (timedwait_signal_wait_cond): Alertable waits on
66 private handles are now interrupted by signalling the same
67 condition that would end the wait if the handle became signalled,
68 rather than polling. (Shared handles still have to poll.)
70 * threads.c (_wapi_thread_queue_apc): Interrupt the thread if it's
73 * handles-private.h (_wapi_handle_current_thread_set_waiting_on):
74 Helper functions to inform the APC queuing functions when threads
75 are waiting for handles, and to interrupt the wait.
77 * wait.c (WaitForMultipleObjectsEx): Need to tell the handle
78 waiting functions if any of the handles in question are shared
80 2007-06-06 Miguel de Icaza <miguel@novell.com>
82 * processes.c (is_managed_binary): Fix for OSX.
84 2007-06-06 Wade Berrier <wberrier@novell.com>
86 * atomic.h (InterlockedExchangePointer): cast to pointer to to silence
87 compiler warnings (autobuild fails the build on this type of warning)
89 2007-05-21 Dick Porter <dick@ximian.com>
91 * io-portability.c (_wapi_g_dir_open): Don't propagate any errors
92 from the second call to g_dir_open, preserve the original error if
93 the second call still fails but clear the error if it succeeds.
95 2007-05-10 Dick Porter <dick@ximian.com>
97 * sockets.c (_wapi_recvfrom): Refine the fix to bug 75705 so EINTR
98 isn't returned if the remote end shuts down cleanly. Fixes zmd
99 and the second example in bug 75705.
101 2007-04-26 Dick Porter <dick@ximian.com>
103 * shared.c (_wapi_shm_semaphores_init): Need to check
104 MONO_DISABLE_SHM in this entry point, as it's called before
105 _wapi_shm_attach(). Fixes bug 81436.
107 2007-04-24 Dick Porter <dick@ximian.com>
109 * sockets.c (_wapi_recvfrom, socket_close): Force recvfrom() to
110 error if the socket is closed while the receive is blocking.
113 2007-04-13 Dick Porter <dick@ximian.com>
116 * shared.c: Complete the reimplementation of disabling of shared
117 memory, by not allocating sysv semaphores when shm disabling has
118 been requested (either at compile time or run time.)
120 * processes.c (CreateProcess): Don't synchronize locking across
121 processes when forking, when shared memory has been disabled.
123 2007-04-06 Andreas Faerber <andreas.faerber@web.de>
126 * wapi_glob.c: remove reference to sys/cdefs.h, use glib instead.
129 2007-04-05 Dick Porter <dick@ximian.com>
132 * io-portability.c (_wapi_io_scandir): Moved from io.c, and
133 changed to use a cut-down version of glob(3) that has been
134 extended to match with case-insensitivity if needed.
137 * wapi_glob.c: Cut down implementation of glob(3), based on
140 2007-03-22 Dick Porter <dick@ximian.com>
142 * sockets.c (_wapi_connect): Do additional checks when connect(2)
143 fails, because some systems don't let it be restarted. Patch
144 based on one submitted by Robert S Wojciechowski <robertw@ssgx.com>,
147 2007-03-09 Jonathan Chambers <joncham@gmail.com>
149 * io-layer.h: Remove UNICODE and _UNICODE defines as
150 these are done by configure.in now.
152 Code is contributed under MIT/X11 license.
154 Thu Mar 8 19:42:17 CET 2007 Paolo Molaro <lupus@ximian.com>
156 * shared.c: partial support for MONO_DISABLE_SHM env var.
158 2007-03-05 Wade Berrier <wberrier@novell.com>
160 * atomic.h: atomic fixes from Michael Matz for for s390
161 and s390x ( bnc #237611 and bxc #80892 )
163 2007-03-05 Miguel de Icaza <miguel@novell.com>
165 * io.c (CreateFile): Use FILE_ATTRIBUTE_TEMPORARY to mean 0600
166 permissions. For 80688
168 (MoveFile): Use errno_copy here, just to avoid a potential
169 errno-changing code in the future from g_free.
171 Also, ignore EXDEV errors as they are handled immediately after
172 (avoid printing out an error).
176 Mon Feb 12 15:50:24 CET 2007 Paolo Molaro <lupus@ximian.com>
178 * shared.c: exit if semaphores can't be created (bug #80616).
180 2007-02-01 Geoff Norton <gnorton@customerdna.com>
182 * collection.c: NetBSD doesn't define PTHREAD_STACK_MIN.
184 2007-01-26 Dick Porter <dick@ximian.com>
187 * sockets.c (_wapi_getsockopt): Windows seems to not reset
188 SO_ERROR values when they're read, contrary to the documentation.
189 Fixes the new issues raised in bug 79878 (example in C showing
190 winsock behaviour attached to that bug.)
192 2007-01-15 Mark Mason <mason@broadcom.com
194 * atomic.h: add locking primitives for MIPS.
196 2007-01-11 Dick Porter <dick@ximian.com>
198 * sockets.c (_wapi_connect): Don't do the SO_BROADCAST setting
199 here, do it in managed code instead.
200 (_wapi_getsockopt): SO_RCVTIMEO and SO_SNDTIMEO use struct
201 timeval, which has a microsecond field, not milliseconds.
202 (_wapi_setsockopt): ditto.
203 (_wapi_setsockopt): Halve the SO_SNDBUF and SO_RCVBUF values on
204 Linux, as the kernel doubles whatever we set.
205 (_wapi_socket): Save socket domain, type and protocol so it can be
207 (socket_disconnect): Implement socket disconnect (closing the
208 socket, but keeping the file descriptor.)
209 (wapi_disconnectex): A basic implementation of DisconnectEx().
210 (wapi_transmitfile): A very basic implementation of
212 (WSAIoctl): Implement the SIO_GET_EXTENSION_FUNCTION_POINTER
215 * socket-private.h (struct _WapiHandle_socket): Record socket
216 domain, type and protocol info so it can be duplicated later.
218 * sockets.h (WSAID_DISCONNECTEX,WSAID_TRANSMITFILE): Structures
219 and defines needed to look up the DisconnectEx() and
220 TransmitFile() functions by GUID.
222 * error.c (errno_to_WSA): Change ETIMEDOUT mapping to
223 WSAETIMEDOUT; add EDESTADDRREQ.
225 * io-layer.h: Need mswsock.h on windows now.
227 2007-01-04 Miguel de Icaza <miguel@novell.com>
229 * io-portability.c (find_file): Fix a coverity warning (scanning
232 2006-12-31 Miguel de Icaza <miguel@novell.com>
234 * io-portability.c (find_file): Do not abort if an empty filename
235 has been passed. This fixes the case where MONO_IOMAP=all would
236 assert if Directory.Exists ("") was called.
238 Mon Dec 18 14:54:37 CET 2006 Paolo Molaro <lupus@ximian.com>
240 * processes.c: moved a free on the error path.
242 Thu Dec 14 21:42:39 CET 2006 Paolo Molaro <lupus@ximian.com>
244 * processes.c: fixed a few memory leaks when executing
247 Mon Nov 27 13:12:17 GMT 2006 Paolo Molaro <lupus@ximian.com>
249 * atomic.h: fix arm compare and exchange (bug #78500).
251 2006-11-23 Dick Porter <dick@ximian.com>
253 * process-private.h (struct _WapiHandle_process): Add 'waited'
256 * processes.c (process_wait): Check the 'waited' parameter not the
257 signalled state when testing if a process has already been waited
258 for, as the child process itself may set signalled when exiting.
261 * wapi-private.h (_WAPI_HANDLE_VERSION): Bump shared data version
263 * shared.c: Now the shared data version has been incremented we
264 can set the counter semaphore initial value correctly
266 2006-11-22 Dick Porter <dick@ximian.com>
268 * processes.c (process_wait): Cope when the background process
269 reaper gets the process we were waiting for. Special case for
270 waiting for our own process to exit. Fixes bug 77736.
272 2006-11-17 Dick Porter <dick@ximian.com>
274 * processes.c: Fix const correctness and typos that caused memory
277 2006-11-17 Miguel de Icaza <miguel@novell.com>
279 * processes.c (ShellExecuteEx): Check error after CreateProcess,
280 thanks to Dick for pointing this out.
282 2006-11-16 Miguel de Icaza <miguel@novell.com>
284 * processes.c (ShellExecuteEx): If we fail to create a process in
285 ShellExecute, then try to use the xdg-open command, and if that
286 fails, try to use the gnome-open command,
288 Refactor the code so that we do not have to duplicate all this
289 code, but instead use a ucs2-aware version of the code to do
292 2006-11-13 Dick Porter <dick@ximian.com>
294 * io.c (_wapi_stat_to_file_attributes): If the file is a symlink
295 add the FILE_ATTRIBUTE_REPARSE_POINT flag. This is an attempt to
296 follow the specs for the windows symlink support, but will
297 probably have to be reworked when I have test data from a vista
298 machine. Fixes bug 79887.
300 2006-11-11 Miguel de Icaza <miguel@novell.com>
302 * handles.c (CloseHandle): Cope here with the new value
303 INVALID_HANDLE_VALUE set on handles.
305 * processes.c (CreateProcess): Initialize the value of hThread to
306 be INVALID_HANDLE_VALUE on failure, not to be NULL. Improvement
309 2006-11-09 Dick Porter <dick@ximian.com>
311 * sockets.c (_wapi_select): Do some sanity checking on the
312 fd_sets, to avoid file descriptors > FD_SETSIZE.
313 (_wapi_FD_CLR, _wapi_FD_ISSET, _wapi_FD_SET): Avoid file
314 descriptors > FD_SETSIZE.
316 2006-10-27 Dick Porter <dick@ximian.com>
318 * io.c (GetFileAttributes): Force symlinks to directories to be
319 returned as a regular file. Fixes bug 79733.
321 2006-10-18 Miguel de Icaza <miguel@novell.com>
323 * io-portability.c (find_in_dir): First string dup, then closedir.
325 2006-10-12 Dick Porter <dick@ximian.com>
327 * processes.c (_wapi_process_reap): Unref a process handle if we
328 reaped it, found by Zoltan. Fixes bug 79286.
329 (process_wait): Don't wait again if we've already waited for a
332 2006-10-11 Sergey Tikhonov <tsv@solvo.ru>
334 * atomic.h: Fix atomic decrement.
336 * mini/cpu-alpha.md: Use native long shift insts
338 * mono/mono/mini/tramp-alpha.c: Implemented
339 mono_arch_patch_delegate_trampoline method
341 * Started work on using global registers
343 * Use byte/word memory load/store insts if cpu supports it
348 2006-10-09 Zoltan Varga <vargaz@gmail.com>
350 * handles.c (timedwait_signal_poll_cond): Add an alertable parameter, and if it
351 is FALSE, avoid busy waiting.
353 * wait.c: Add an alertable parameter to the wait routines.
355 2006-10-06 Miguel de Icaza <miguel@novell.com>
357 * io-portability.c (find_file): Rename from
358 MONO_IO_PORTABILITY_HELP to MONO_IOMAP.
360 2006-10-03 Dick Porter <dick@ximian.com>
363 * io-portability.c: Optional portability helpers and wrapped
364 system calls to try to cope with windows filenames in
367 * io.c: Use the wrapped system calls
369 2006-09-01 Zoltan Varga <vargaz@gmail.com>
371 * critical-sections.h critical-sections.c: Make Enter/LeaveCriticalSection a macro
372 since they are perf critical.
374 * atomic.h: Applied patch from Jakub Boqusz <qboosh@pld-linux.org>.
375 Add atomic ops implementation for alpha.
377 2006-08-11 Dick Porter <dick@ximian.com>
379 * processes.c (_wapi_process_reap): Avoid a deadlock by setting
380 process termination details in an outer loop, not the
381 _wapi_search_handle() one.
383 2006-08-10 Dick Porter <dick@ximian.com>
385 * threads.c (_wapi_thread_queue_apc)
386 (_wapi_thread_dispatch_apc_queue): Use a process-local mutex here
387 instead of the cross process semaphore. We already check that
388 access to the APC queue is within the owning process so there's no
389 need to protect from other processes. Avoids a global deadlock
390 when a thread is aborted while it holds the handle semaphore
392 (_wapi_thread_apc_pending): Hide an annoying message which can
393 happen if a thread handle has been blown away at process shutdown
394 while it is in an alertable wait.
396 Both problems seen while shutting down monodevelop.
398 2006-07-25 Dick Porter <dick@ximian.com>
400 * shared.c (_wapi_shm_file): Remove '/' characters from the uname
401 results. Fixes bug 78917.
403 2006-07-20 Dick Porter <dick@ximian.com>
405 * threads.c (_wapi_thread_set_termination_details): Improve the
406 test for already-disposed thread handles, and hold the lock around
407 the mutex abandoning.
409 2006-07-17 Dick Porter <dick@ximian.com>
411 * processes.c (CreateProcess): Don't change directory unless a new
412 one has been specified. Fixes bug 78751.
414 2006-07-06 Dick Porter <dick@ximian.com>
416 * io.c (_wapi_stat_to_file_attributes): Do a better job at
417 figuring out the file attributes
418 (_wapi_set_last_path_error_from_errno): New helper function to
419 turn errno into w32 error codes that handles the differences
420 between file and directory errors
421 (file_setendoffile): Try turning off the extra write used to
422 extend files, because we probably don't need it on any modern
423 platform. If it is needed though, we also need to lseek the file
425 (CreateFile): Treat character-special devices as a console handle,
426 because they can't be seeked
427 (CopyFile): If fail_if_exists is set, then the destination needs
428 to be opened with O_EXCL
429 (CopyFile): If fail_if_exists is not set and the destination
430 already exists, then we should set the ERROR_ALREADY_EXISTS error
431 even though we return success
432 (stdhandle_create): STD_INPUT_HANDLES cannot be written to
433 (GetStdHandle): Rework without using mono_once, so console handles
434 can be properly closed and reopened.
435 (mono_io_scandir): Only override errno with EACCES when the
436 directory actually exists
437 (FindFirstFile): Set ERROR_FILE_NOT_FOUND when no files are
439 (FindClose): Cope with NULL handles
440 (CreateDirectory): When the target already exists, just return an
441 error. It's the caller's job to figure out what to do.
442 (SetCurrentDirectory): Cope with a NULL path
443 (RemoveDirectory, GetFileAttributes, GetFileAttributesEx,
444 SetFileAttributes, FindFirstFile, DeleteFile, MoveFile, CopyFile,
445 CreateFile): Set path error correctly
447 * handles.c (CloseHandle): Kludge to try and cope with passing a
450 * error.h: Add NO_ERROR as an alternative to ERROR_SUCCESS
452 * uglify.h: Added some more typedefs
454 2006-07-05 Dick Porter <dick@ximian.com>
456 * io.c (GetFileAttributes, GetFileAttributesEx): Cope with
457 dangling symlinks. Fixes bug 78664.
459 2006-06-23 Dick Porter <dick@ximian.com>
461 * handles.c (handle_cleanup):
462 * threads.c: Clean up threads properly when we're forcibly
463 removing the handle entries from the shared file in
464 handle_cleanup(). Fixes bug 78241, for real this time.
466 2006-06-15 Neale Ferguson <neale@sinenomine.net>
468 * atomic.h: More tinkering with InterlockedExchange/InterlockedCompareExchange
471 2006-06-14 Neale Ferguson <neale@sinenomine.net>
473 * atomic.h: Fix atomic exchange pointer operations for s390x - these
474 were broken as they used 32-bit instructions rather than their 64-bit
477 2006-06-14 Dick Porter <dick@ximian.com>
479 * processes.c: Don't run the atexit handlers when bailing out
482 2006-06-14 Dick Porter <dick@ximian.com>
484 * wait.c: Fix stupid typo shown up by gcc 4.1.1, = not ==
492 * collection.c: Fix a bunch of signed/unsigned warnings from gcc
495 2006-06-09 Neale Ferguson <neale@sinenomine.net>
497 * atomic.h: Fix atomic operations for s390x (not really broken
498 but changed to use full 64-bit opcodes).
500 2006-05-24 Dick Porter <dick@ximian.com>
502 * processes.c (process_set_current): Don't take an extra reference
503 if we have to create our own process handle. Fixes bug 78241
506 * threads.c (_wapi_thread_signal_self): Renamed from
507 _wapi_thread_abandon_mutexes, also sets the thread state to
508 signalled and drops a reference. Called by the runtime when the
509 main thread cleans itself up.
511 * handles.c (handle_cleanup): As a last resort, unref every shared
512 handle as the process is now exiting.
514 2006-05-16 Dick Porter <dick@ximian.com>
516 * processes.c (process_set_termination_details): Unref the handle
517 when we've stored the exit details. Fixes the rest of 78241.
519 2006-05-12 Dick Porter <dick@ximian.com>
521 * threads.c: Implement pseudo handles, making GetCurrentThread()
522 match MS behaviour. Notice when attached threads exit, and unref
523 the handle. Fix usage of GetCurrentThread() in other places.
525 * handles.c (DuplicateHandle): Implement a basic form of
528 * wait.c: Fix usage of GetCurrentThread() throughout, and cope
531 2006-04-26 Miguel de Icaza <miguel@novell.com>
533 * io.c (file_close): Oops, do not use DeleteFile which expects
534 unicode, instead use unlink directly
536 Add support for the new FileOptions bits on .NET 2.0.
538 It might be good if Dick reviews these changes.
540 * io.c (file_close): If DeleteOnClose is set, then delete the file
542 (CreateFile): Do not support encryption per user.
544 If posix_fadvise exists, pass hints on sequential scan and random
545 access. Did not figure out what WRITE_THROUGH maps to.
547 2006-04-26 Dick Porter <dick@ximian.com>
549 * sockets.c (WSAIoctl): Check the output buffer is valid before
552 * handles.c (_wapi_search_handle): Set shared pointer if we find a
553 shared handle that has been already opened.
555 2006-04-21 Dick Porter <dick@ximian.com>
557 * threads.c (GetCurrentThread): Reference the handle if we return
558 an already-known thread.
560 2006-04-07 Dick Porter <dick@ximian.com>
562 * processes.c: Fix build for older glib.
564 2006-04-06 Dick Porter <dick@ximian.com>
566 * processes.c (CreateProcess): Add a reference to the child
567 process' handle, so it won't be destroyed if this process closes
568 its copy of the handle. Fixes bug 77393.
570 * processes.c (process_set_current): Fall through to creating a
571 new one if the handle lookup fails.
573 * processes.c (_wapi_process_signal_self):
574 * handles.c (handle_cleanup): The process is exiting, so set the
575 handle state for this process to signalled. This should let other
576 non-related processes wait for this handle.
578 * handles.c (_wapi_search_handle): Don't search shared handles in
581 * collection.c (collection_thread): No need to do a collection
582 scan straight away, do the waiting first.
584 2006-04-06 Dick Porter <dick@ximian.com>
586 * shared.c: Fix parameters in semctl () call.
588 2006-03-28 Zoltan Varga <vargaz@gmail.com>
590 * atomic.h atomic.c: Applied patch from David S. Miller
591 <davem@davemloft.net>: Reimplement Interlocked* primitives on sparc
592 using CAS/CASx when __GNUC__, else we will fall back to the generic
595 2006-03-27 Dick Porter <dick@ximian.com>
597 * shared.c (_wapi_shm_file_open): Break out of a loop if the
598 shared file is smaller than expected. (We loop a few times in
599 case another process is in the middle of creating the file.)
601 2006-03-22 Dick Porter <dick@ximian.com>
606 * shared.c: Delete the semaphores and shared files when the last
607 process has finished with them
609 2006-03-15 Dick Porter <dick@ximian.com>
617 * threads.c: Explicitly initialise the handle ops struct
619 2006-03-14 Dick Porter <dick@ximian.com>
624 * handles.c: Add a 'prewait' stage to the handle waiting, to give
625 waiting threads a chance to check for bogus states before
628 * mutexes.c (namedmutex_prewait): Use the prewait stage to check
629 for named mutexes that have been abandoned in a locked state (eg
630 if a process exited abnormally while owning the mutex) and
631 override it if needed.
633 2006-03-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
635 * wait.c: speed up WaitFor* when the timeout is 0.
637 2006-03-03 Dick Porter <dick@ximian.com>
639 * processes.c (ShellExecuteEx): Cope when some of the parameters
642 2006-02-27 Dick Porter <dick@ximian.com>
646 * threads.c: Comparing pthread_t with == is not portable, so use
649 Thu Feb 23 18:47:20 GMT 2006 Paolo Molaro <lupus@ximian.com>
651 * *.h, *.h: patch from Dick to make Linuxthreads systems work again.
653 2006-02-22 Dick Porter <dick@ximian.com>
656 * threads.c: There's no need to use the timed-thread support code
657 any more, as we aren't using the timed join. This greatly
658 simplifies thread setup, and fixes a memory leak (bug 77521).
660 Don't bother to store thread IDs in a hash table, use TLS instead.
661 The one case that needs to look up the handle of a different
662 thread (OpenThread()) can do the extra work itself. Fixes bug
665 * handles.c (_wapi_search_handle): Add a reference when returning
666 a private handle (shared handles are already reffed.)
668 2006-02-17 Dick Porter <dick@ximian.com>
671 * handles.c: Check handle values passed to array lookups. Fixes
674 2006-02-09 Dick Porter <dick@ximian.com>
676 * threads.c: Cope with the problems caused by attaching already
677 existing threads - they don't get the infrastructure to clean up
678 after themselves, especially the ID to handle hash. This fixes
681 2006-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
683 * shared.c: use MONO_SHARED_HOSTNAME as a substitute for gethostname()
684 when creating the shared files in the .wapi directory. Fixes bug #77371.
686 2006-02-02 Martin Baulig <martin@ximian.com>
688 * threads.c: Removed the `WITH_INCLUDED_LIBGC' section; it has
689 never been used so far.
691 * timed-thread.h (TimedThread): Removed the `stack_ptr' field; it
692 has only been used by the removed code.
694 2006-01-03 Neale Ferguson <neale@sinenomine.net>
696 * atomic.h: Correct s390x definitions and eliminate compiler warnings.
698 2006-01-03 Sebastien Pouliot <sebastien@ximian.com>
700 * io.c: Patch _wapi_stat_to_file_attributes against bug #76966, where
701 sockets could be considered as directory.
703 2005-12-23 Dick Porter <dick@ximian.com>
707 * semaphores.c: Implement OpenSemaphore
710 * mutexes.h: Implement OpenMutex
716 * event-private.h: Implement named events. Implement OpenEvent.
718 2005-12-15 Dick Porter <dick@ximian.com>
720 * processes.c (CreateProcess): The pipe-based cross-process
721 exclusion technique was trying to write NULL buffers when appname
722 was NULL (eg when coming from ShellExecuteEx,) which usually
723 succeeded even though EFAULT was returned - but sometimes it
724 failed. This meant that the child process could block forever on
725 the pipe read. Replace it with the simpler shared handle
726 semaphore protection used everywhere else. This showed up with
727 the test case in bug 76684.
729 Tue Dec 13 11:41:49 GMT 2005 Paolo Molaro <lupus@ximian.com>
731 * shared.c: fallback to private mmap when shared mmap doesn't work
734 2005-12-06 Dick Porter <dick@ximian.com>
738 * semaphore-private.h:
739 * semaphores.c: Implement named semaphores
741 2005-11-24 Dick Porter <dick@ximian.com>
743 * processes.c (GetProcessId): Implement GetProcessId()
745 2005-11-17 Dick Porter <dick@ximian.com>
748 * processes.c: Implement ShellExecuteEx as a wrapper around
751 2005-11-11 Dick Porter <dick@ximian.com>
753 * threads.c: Give mutex abandoning its own exported function, so
754 it can be called when the runtime is cleaning up.
756 * handles.c (_wapi_search_handle_namespace): Do a handle
757 collection befre starting to check namespace strings, so that any
758 stale cruft gets removed.
760 2005-11-11 Dick Porter <dick@ximian.com>
762 * threads.c: Move thread handles back into the shared space.
764 * handles.c (_wapi_handle_unref): Add support for shared handles
765 with close() handlers
767 2005-11-04 Dick Porter <dick@ximian.com>
769 * sockets.c (ioctlsocket): Use select instead of if to avoid a
770 type promotion problem on 64bit freebsd. Based on patch by Lou
771 Kamenov <kamenovl@gmail.com>, fixes bug 76447.
773 2005-11-04 Dick Porter <dick@ximian.com>
775 * io.c (file_write): Only do the file locking if
776 MONO_STRICT_IO_EMULATION is set.
778 2005-10-21 Dick Porter <dick@ximian.com>
781 * handles.c (_wapi_lookup_handle): Cope when the shared part of a
782 handle has been deleted.
783 (_wapi_handle_unref): And when the deleted shared part is pointed
784 to as a handle is deleted
786 2005-10-20 Dick Porter <dick@ximian.com>
788 * processes.c (process_set_current): If the expected process
789 handle slot doesn't contain the correct pid, create a new handle.
791 * handles.c (_wapi_search_handle): When the search doesn't find
792 anything, return failure instead of the last handle we looked at.
793 (_wapi_handle_ref, _wapi_handle_unref): Don't try to ref or unref
794 unused handles (makes tracking refcounting bugs easier.)
796 2005-10-19 Dick Porter <dick@ximian.com>
803 * collection.c (_wapi_handle_collect): Remove the shared handle
804 indirection layer, and use locking instead. Delete other
805 complexity that is no longer needed. Refcount shared handles and
806 delete them when needed, but keep the timestamps so that orphaned
807 handles will be cleaned up eventually.
809 * shared.c (_wapi_shm_file): Add processor, OS and struct size
810 info to the shared file names, to cope with dual-boot and 32/64bit
811 size issues. Fixes bug 75839.
813 * wait.c (WaitForMultipleObjectsEx): No need to distinguish
814 between shared handles and private, as the wait functions cope
815 with both together now.
817 2005-10-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
819 * io.c: removed NO_SIGPIPE macro.
820 * sockets.c: no need for MSG_NOSIGNAL or ignoring SIGPIPE.
822 2005-10-11 Dick Porter <dick@ximian.com>
824 * sockets.c (_wapi_getsockopt): Translate SO_ERROR results into
827 * error.c (errno_to_WSA): Don't return a bogus error if someone
828 asks to translate errno 0.
830 2005-10-11 Dick Porter <dick@ximian.com>
832 * handles.c: Fix several race conditions
834 2005-10-11 Miguel de Icaza <miguel@novell.com>
836 * io.c: no need to block SIGPIPE anymore, as it is ignored.
838 2005-10-05 Dick Porter <dick@ximian.com>
840 * threads.c (_wapi_thread_own_mutex, _wapi_thread_disown_mutex):
841 Keep a reference to mutexes owned by threads, so they won't be
842 destroyed prematurely. Fixes dotmsnclient crash.
844 2005-09-26 Sebastien Pouliot <sebastien@ximian.com>
846 * io.c: Apply patch from #76192 (Can't write files past 2gb on AMD64
847 (x86_64)) for Brion on IRC (Dick approved it).
849 2005-09-23 Dick Porter <dick@ximian.com>
851 * processes.c: Don't wait for processes that have already been
852 signalled; also fix typo.
854 * handles.c: Improve locking inside new handle and handle
857 2005-09-20 Dick Porter <dick@ximian.com>
860 * processes.c: Periodically waitpid for known process IDs. Fixes
863 2005-09-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
866 (CreateFile): if the file is a named pipe, treat the handle as a pipe,
867 not as a file. Fixes bug #76075.
869 2005-08-27 Zoltan Varga <vargaz@gmail.com>
871 * atomic.h: Add support for intel icc.
873 2005-08-25 Zoltan Varga <vargaz@gmail.com>
875 * io-layer.h: Include winbase.h not WinBase.h.
877 2005-08-19 Dick Porter <dick@ximian.com>
879 * threads.c, threads.h, thread-private.h: Use a gsize to store the
880 thread ID, so it can hold a 64 bit value if needed.
882 2005-07-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
884 * error.c: map ENOENT to WSAECONNREFUSED. It might happen when
885 connecting to unix sockets. Closes bug #75632.
887 2005-07-05 Dick Porter <dick@ximian.com>
889 * io.c: Make sure SIGPIPE is ignored when calling write(2).
890 Prevents the runtime exiting when writing to a closed pipe,
893 2005-06-30 Dick Porter <dick@ximian.com>
895 * shared.c (_wapi_shm_semaphores_init): Add some helpful error
896 messages when semget () fails due to lack of resources.
898 2005-06-21 Dick Porter <dick@ximian.com>
903 * threads.c: Keep a list of owned mutexes in each thread handle,
904 so that it is easier to abandon them when the thread exits.
905 Removes a bottleneck when multiple threads are finishing in
908 2005-06-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
910 * io.c: (GetLogicalDrives) when a bogus line is read, don't leak memory.
911 When the buffer has not enough space, close the file before returning.
913 2005-06-09 Duncan Mak <duncan@novell.com>
915 * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to
916 all public headers. Fixes #74919.
918 2005-05-30 Zoltan Varga <vargaz@freemail.hu>
920 * atomic.h: Add IA64 atomic ops.
922 2005-05-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
924 * processes.c: make ExitCode be valid even if the user didn't call
925 WaitForExit() and is just polling on HasExited.
927 2005-05-17 Dick Porter <dick@ximian.com>
929 * io.c (file_getfilesize): Clear the error value, so that files
930 with sizes with the low bits 0xFFFFFFFF can be distinguished from
933 2005-05-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
935 * shared.c: forgot to ignore a warning.
937 2005-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
939 * shared.c: don't display warnings after reboots.
941 2005-05-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
943 * sockets.c: on windows, getsockopt/setsockopt for send/receive timeout
944 use an integer in milliseconds. We were using a struct timeval.
946 2005-05-06 Dick Porter <dick@ximian.com>
955 * collection.h: Use SysV semaphores for managing access to the
956 shared memory - in return for the ludicrous api we get
957 synchronisation primitives that can be cleaned up by the kernel
958 even when a process quits unexpectedly. This removes the
961 2005-05-05 Lluis Sanchez Gual <lluis@novell.com>
963 * handles.c: Always use polling in the waits, since
964 mono_cond_timedwait can't be interruped by the thread abort signal.
966 2005-04-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>
968 * events.c: calling Set on AutoResetEvent several times has the same
969 effect as calling it only once if no thread is waiting for it.
971 2005-04-29 Dick Porter <dick@ximian.com>
973 * processes.c (EnumProcesses): Use a GArray instead of a GPtrArray
974 now it's storing pids not handles, also fixes memory leak caused
975 by unclear glib documentation.
977 * sockets.c (WSACleanup): Remove unused variable
979 2005-04-29 Dick Porter <dick@ximian.com>
981 * handles.c (_wapi_handle_check_share_by_pid): For systems that
982 don't have file descriptor info in /proc check that the original
983 opener of a file is still there, if a share violation would
986 2005-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
989 * handles-private.h: added _wapi_handle_forecch that loops through all
990 the handles and call a callback function when a handle of the given
993 * sockets.c: no need to keep open sockets in an array, as we have them
994 in the handles structure.
998 2005-04-28 Dick Porter <dick@ximian.com>
1000 * processes.c: Cope with handles that are only around for as long
1001 as the search is running. If we're searching for process handles,
1002 check to see if the process is still running and signal it if not.
1004 * handles.c (_wapi_search_handle): Search in the shared space as
1005 well. Fixed bug 74752.
1008 * handles.c (_wapi_handle_new_from_offset):
1009 _wapi_handle_new_for_existing_ns () was doing exactly the same as
1010 this, so deleted it.
1012 2005-04-26 Dick Porter <dick@ximian.com>
1014 * handles.c: Fix stupid thinko where if a new shared handle is
1015 created but a collection was needed to free some space, it
1016 returned an error anyway. Should fix the messages shown in bug
1019 2005-04-25 Dick Porter <dick@ximian.com>
1021 * handles.c (_wapi_handle_check_share): Only consider mono
1022 processes when looking to see if a file is still being held open,
1023 while checking share permissions.
1025 2005-04-25 Dick Porter <dick@ximian.com>
1029 * wapi-private.h (struct _WapiHandleOps):
1030 * handles.c (_wapi_handle_unref): When destroying handles, save
1031 the handle data and call the close function only after the array
1032 slot has been cleared. This prevents race conditions with file
1033 descriptors, fixing bug 74713.
1035 * mutexes.c: Delete the handle close functions, they didn't do
1038 * error.c (_wapi_get_win32_file_error): Add a mapping for EINTR so
1039 the "Unknown error" g_warning doesn't get displayed.
1041 2005-04-25 Dick Porter <dick@ximian.com>
1044 * threads.c: Make thread handles process-private for now to take
1045 some of the space pressure off the shared memory, while I work on
1048 2005-04-21 Dick Porter <dick@ximian.com>
1050 * handles.c (_wapi_handle_check_share): Make sure there is a "fd"
1051 dir in /proc before blowing away handle info. Fixes bug 74649.
1053 2005-04-21 Dick Porter <dick@ximian.com>
1055 * wait.c (WaitForMultipleObjectsEx): Implement special waits
1057 * handles.c (_wapi_handle_wait_signal_poll_share): Don't return a
1058 timeout, just wait briefly for the private signals and let the
1059 waiting thread test again. This prevents us missing shared
1062 2005-04-21 Dick Porter <dick@ximian.com>
1064 * collection.h (_WAPI_HANDLE_COLLECTION_EXPIRED_INTERVAL): Reduce
1065 the time before a slot is considered too old and deleted. This is
1066 a workaround while I come up with a proper fix.
1068 2005-04-21 Dick Porter <dick@ximian.com>
1073 * handles.c (_wapi_handle_new): Turn assertions into errors.
1075 * collection.c (_wapi_handle_collect): Use symbols not magic
1076 numbers for timeout values
1078 2005-04-19 Dick Porter <dick@ximian.com>
1082 * handles.c (_wapi_handle_count_signalled_handles)
1083 * handles-private.h (_wapi_handle_shared_lock_handle): Use new
1084 shared handle locks in critical sections.
1086 * handles.c (_wapi_handle_new_for_existing_ns): Reuse old handles
1087 if there is already one there.
1089 * handles.c (_wapi_handle_ref): It was possible for a process to
1090 exit before getting around to updating shared handle timestamps,
1093 Tue Apr 19 16:25:47 CEST 2005 Paolo Molaro <lupus@ximian.com>
1095 * threads.c: fix lookup of the thread id in the has table:
1096 always use the id value, not the pointer to the id.
1098 2005-04-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1100 * handles.c: fix handle returned in _wapi_handle_search_handle. Dick
1103 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1105 * io-layer/sockets.c: FIONBIO with a TRUE argument means we want
1106 non-blocking IO, not the other way around.
1108 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1112 * handles-private.h: GetFileType wasn't checking if we have memory
1113 allocated for the handle before dereferencing it. Fixes a FileStream
1116 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1120 * handles-private.h: we were calling g_renew to expand the handle array,
1121 but that might move the memory and we might have pthread conditions or
1122 mutexes in the original memory area that are being used. Now instead of
1123 expanding an existing array, we just create new ones and keep a list of
1124 them. Access to _wapi_private_handles had to be modified accordingly.
1126 2005-04-15 Dick Porter <dick@ximian.com>
1128 * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN
1130 2005-04-14 Raja R Harinath <rharinath@novell.com>
1132 * wapi-private.h: Remove reference to 'daemon-private.h'.
1134 Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro <lupus@ximian.com>
1136 * atomic.h: applied patch from mass@akuma.org (David Waite)
1137 to fix InterlockedExchangeAdd.
1138 Fixed a few other functions, including InterlockedCompareExchange()
1139 which was miscompiled by gcc with optimizations enabled.
1141 2005-04-13 Dick Porter <dick@ximian.com>
1143 * io.c (share_check):
1144 * handles.c (_wapi_handle_check_share): Refine the file check so
1145 that sharing violations within the same process don't cause
1148 2005-04-13 Dick Porter <dick@ximian.com>
1150 * io.c (FindFirstFile): Fix bugs introduced with the merge (bug
1153 2005-04-12 Dick Porter <dick@ximian.com>
1155 The daemon-less io-layer. Extensive lowlevel changes in
1156 handles.c, requiring some corresponding changes in other files
1157 calling these functions. Private_foo structures have been
1160 File descriptor handling differences account for most of the
1161 changes in io.c and sockets.c.
1165 * mutexes.c: Named mutexes are now a distinct type.
1166 * atomic.h: Fix a PPC uninitialised variable warning.
1167 * wait.c: Check conditions before waiting on a condition variable.
1168 * processes.c: Handle process fork and wait without a daemon
1169 (though this has the limitation of only being able to wait for
1172 2005-04-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1179 * sockets.h: removed dead code that deals with async IO.
1181 2005-03-30 Zoltan Varga <vargaz@freemail.hu>
1183 * atomic.c (InterlockedIncrement): Fix fallback implementation of
1184 InterlockedIncrement and InterlockedDecrement. Fixes #74228.
1186 2005-03-29 Sebastien Pouliot <sebastien@ximian.com>
1188 * io-layer.h: Add required header files for compiling with VS.NET.
1190 2005-03-17 Miguel de Icaza <miguel@novell.com>
1192 * io.c: don't fail on NFS when there are no more locks available.
1194 2005-03-09 Dick Porter <dick@ximian.com>
1196 * error.c (_wapi_get_win32_file_error): ENFILE and EMFILE should
1197 map to ERROR_TOO_MANY_OPEN_FILES, not ERROR_NO_MORE_FILES. Fixes
1200 2005-03-09 Dick Porter <dick@ximian.com>
1202 * daemon.c (process_process_fork): Initialise the handle data
1203 before using it in the error case. This is probably the error
1204 we're working around in the previous change. Spotted by Taru Jain
1205 <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.
1207 2005-03-07 Dick Porter <dick@ximian.com>
1209 * daemon.c: It looks like g_shell_parse_argv() can return
1210 argv[0]=NULL somehow, yet still not give an error. Make sure we
1211 don't pass NULL to strrchr(), working around a segfault that
1212 showed up on ZLM testing.
1214 2005-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1216 * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is
1217 the expected error code showed by the test case in bug #73053.
1219 2005-02-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1221 * io.c: another leftover.
1223 Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1225 * io.c: fixed logic in checking errno in rev 40815.
1227 Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1229 * threads.c: we don't depend on the GC checking tls
1231 * processes.c: remove unused ref to GC headers.
1233 Thu Feb 17 19:57:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1235 * io.c: remove _wapi_thread_cur_apc_pending () checks
1236 when the siscall should return immediatly and handle
1237 the case when a syscall is interrupted without
1238 erroring out, but returning a 0 read/write if possible.
1239 Still the cases of read from file need to be handled.
1241 Tue Feb 8 18:28:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1243 * threads.c: make people test with 1 MB stack per thread.
1245 2005-01-17 Dick Porter <dick@ximian.com>
1247 * timefuncs.h: Make WapiFileTime endian-aware, as it's often
1248 cast to and from 64bit ints. Fixes bug 71213.
1250 2005-01-11 Dick Porter <dick@ximian.com>
1252 * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
1255 Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>
1257 * atomic.h: Fix functions on s390.
1259 Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>
1261 * atomic.h: fix some functions on ppc (tests/interlocked.cs).
1263 2005-01-10 Dick Porter <dick@ximian.com>
1265 * misc.c (_wapi_calc_timeout): Guard against overflow when
1266 calculating timeouts. This makes waiting with a large
1267 (Int32.MaxValue) timeout not return immediately.
1269 2004-12-23 Ben Maurer <bmaurer@ximian.com>
1271 * io.c (io_ops): make this `const' so it is shareable (well, only
1272 really shareable if it is statically linked...)
1274 Mon Dec 20 11:58:33 CET 2004 Paolo Molaro <lupus@ximian.com>
1276 * threads.c, threads.h: add accessor to get the pthread_key_t for
1279 2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1281 * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS
1282 if it exists and is not the same as 'src'.
1284 2004-12-01 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1286 * atomic.h : Fix InterlockedCompareExchange for s390/s390x.
1288 2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1290 * processes.c: unquote the cmd path, allow for ' or " when quoting and
1291 pass the quoted program name to the daemon, otherwise the call to
1292 g_shell_unquote in the daemon will break things up.
1294 2004-10-14 Dick Porter <dick@ximian.com>
1296 * sockets.c (_wapi_accept): Revert the previous change. We now
1297 set the accepted socket to have the same blocking status as the
1298 listening socket in managed code. This follows MS behaviour.
1300 2004-10-14 Dick Porter <dick@ximian.com>
1302 * sockets.c (_wapi_accept): On Darwin, make sure a newly
1303 accept()ed socket is blocking. Fixes bug 67355, patch by
1304 grompf@sublimeintervention.com.
1306 2004-10-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1308 * system.c: check the number of online processors instead of the
1309 existing ones. Sanitize return value if it's an error.
1311 2004-10-03 Ben Maurer <bmaurer@ximian.com>
1313 * system.c: Add support for getting the # of cpus.
1315 2004-09-28 Dick Porter <dick@ximian.com>
1317 * io.c (pipe_close_private): Fix one small typo in the last change
1318 that totally hosed process creation with redirected pipes.
1320 2004-09-24 Dick Porter <dick@ximian.com>
1327 * handles-private.h: Cope when a file descriptor is reused while
1328 the handle that thought it owned it is still referenced, instead
1329 of asserting. Probably fixes bug 66479, though we've been unable
1332 2004-09-09 Dick Porter <dick@ximian.com>
1335 * io.c: Set error codes everywhere.
1337 2004-09-06 Dick Porter <dick@ximian.com>
1339 * handles.c (_wapi_handle_unref): Reset the private record's type
1340 (CloseHandle): Check for a fd mapping failure, and return FALSE.
1341 (_wapi_handle_process_fork): Fix long-standing bug in checking
1342 handle return values. Also do the required bookkeeping with the
1343 new process's handles.
1345 * daemon.c: When creating a new process's handles, check whether
1346 the shared space needs to be increased
1348 2004-09-05 Zoltan Varga <vargaz@freemail.hu>
1350 * shared.c (_wapi_shm_file): Fix leaking of filename.
1352 2004-08-19 Dick Porter <dick@ximian.com>
1354 * handles.c (_wapi_handle_count_signalled_handles): Fix thinko
1355 introduced with the fd offset stuff: unlock handles properly when
1356 backing off. Fixes the monologue hang at exit.
1358 2004-08-18 Dick Porter <dick@ximian.com>
1361 * io.c: Check that new fds fit in the table, return error if not
1363 * daemon.c (_wapi_daemon_main):
1364 * handles.c (shared_init): Have all processes agree on a size for
1367 2004-08-17 Dick Porter <dick@ximian.com>
1369 * daemon.c (process_new):
1370 * handles.c (_wapi_handle_new_internal): Cope when the space
1371 reserved for file descriptors is larger than the shared segment
1372 size. Fixes the crash reported when running mono under gdb on
1375 2004-08-16 Dick Porter <dick@ximian.com>
1379 * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
1380 error checking with passed-in file descriptors.
1382 2004-08-11 Dick Porter <dick@ximian.com>
1385 * io.c: Returned handle values are the file descriptor the handle
1389 * handles-private.h:
1390 * daemon.c: Reserve the range of handles that can have the same
1391 values as file descriptors. These won't be used, but the values
1392 will be used as file, console, pipe or socket handles. The fd to
1393 handle mapping is done internally and is invisible to users.
1396 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
1397 reserve a chunk of handle space.
1399 2004-08-04 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1401 * atomic.h: add support for 64-bit S/390
1403 2004-07-22 Dick Porter <dick@ximian.com>
1406 * threads.c: Move the destruction of the internal thread data to
1407 after the thread has been joined. Fixes bug 61418.
1409 2004-07-14 Dick Porter <dick@ximian.com>
1411 * wait.c (test_and_own): When not waiting for all handles to
1412 become signalled, only own and return the lowest. All the
1413 documentation suggests that the old way was correct, but
1414 experimentation shows it actually works like this. Patch by
1415 Sébastien Robitaille
1416 (sebastien.robitaille@croesus.com), fixes bug 61511.
1418 2004-07-09 Ben Maurer <bmaurer@ximian.com>
1420 * threads.c: register roots for gc
1422 2004-07-08 Dick Porter <dick@ximian.com>
1424 * io.c (file_seek): If there is a high 32bit offset part, make
1425 sure the low part isn't sign-extended. Set error codes when
1426 returning failure. Fixes bug 61131.
1428 2004-07-06 Dick Porter <dick@ximian.com>
1430 * io.c (file_setfiletime): Check for underflow when converting to
1431 time_t values. Set error codes when returning failure. Fixes bug
1434 2004-07-05 Dick Porter <dick@ximian.com>
1436 * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable.
1438 * daemon.c (unref_handle): Only destroy a handle if all processes
1439 have released it, not just the current one. Fixes bug 60887.
1441 2004-06-30 Zoltan Varga <vargaz@freemail.hu>
1443 * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
1444 to prevent warnings.
1446 2004-06-24 Dick Porter <dick@ximian.com>
1448 * mutexes.c: Indicate when a named mutex was reused
1450 2004-06-24 Dick Porter <dick@ximian.com>
1452 * threads.c (SuspendThread):
1453 * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a
1454 while loop. See bug 58161.
1456 Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro <lupus@ximian.com>
1458 * io.c: don't use sharemode for on-disk file permissions: it's used
1459 for shared access to the open file.
1461 2004-06-22 Dick Porter <dick@ximian.com>
1463 * events.c (CreateEvent): When creating an auto-reset event that
1464 is initially owned, make sure the set count starts at 1.
1466 2004-06-18 Dick Porter <dick@ximian.com>
1469 * events.c: Auto-reset events need to release one thread for each
1470 time SetEvent() is called. Fixes bug 41292.
1474 * mutexes.c: Scan for mutexes that are still locked by a thread
1475 when it exits. Fixes the MS demo app linked by bug 41292.
1477 * wait.c (test_and_own): Make sure a handle is signalled before it
1480 2004-06-16 Dick Porter <dick@ximian.com>
1482 * timed-thread.c: Call the thread cleanup exit routine before taking
1483 the join mutex, because this could deadlock if another thread tries
1484 to join in the meantime. This fixes the hang-at-exit problem seen
1487 2004-06-03 Lluis Sanchez Gual <lluis@ximian.com>
1489 * threads.c: Implemented SleepEx.
1490 * threads.h: Fixed SleepEx signature.
1492 2004-06-03 Miguel de Icaza <miguel@ximian.com>
1494 * threads.c: When running under valgrind, do not allocate too much
1495 stack, as Valgrind default is 1 meg.
1497 2004-05-27 Dick Porter <dick@ximian.com>
1500 * io.c: Implemented LockFile() and UnlockFile()
1502 2004-05-21 Dick Porter <dick@ximian.com>
1504 * io.c (CreateFile): Check for existing share modes when opening
1508 * handles-private.h:
1509 * daemon-messages.h:
1510 * daemon.c: Maintain a hash of file share modes, keying on device
1511 and inode (to cope with symlinks.)
1513 2004-05-20 Lluis Sanchez Gual <lluis@ximian.com>
1515 * daemon-messages.c: Retry if the communication with the daemon is
1516 interrupted by a signal.
1517 * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped.
1518 Only return an error in this case if there is something in the apc queue
1519 (which means that it is an interruption requested by the "user").
1520 * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as
1521 true since the wait is small.
1522 * shared.c: Retry write calls when interrumped by a signal.
1523 * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which
1524 returns TRUE if there are pending asynchronous calls (APC) for the
1525 provided thread. Also added _wapi_thread_dispatch_apc_queue which calls
1526 the enqueued APCs. Defined a new struct ApcInfo that holds information
1527 about an enqueued APC.
1528 * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same
1529 as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue.
1530 These last two methods call the corresponding apc methods in
1531 thread-private using the provided thread handle.
1532 * threads.h: Added QueueUserAPC.
1533 * uglify.h: Added WapiApcProc (needed by QueueUserAPC).
1534 * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and
1535 WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support
1536 for APCs in those two methods and also in SleepEx.
1538 2004-05-17 Dick Porter <dick@ximian.com>
1540 * io.c (CopyFile): Speed up. Fixes bug 57859.
1542 2004-05-13 Dick Porter <dick@ximian.com>
1543 * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current
1544 thread doesn't own the mutex, rather than assert()ing.
1546 2004-05-11 Dick Porter <dick@ximian.com>
1548 * shared.c (_wapi_shm_attach): Cope when a previous daemon startup
1549 attempt failed, leaving shared files that look like a daemon is
1552 2004-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1555 (SetFileAttributes): don't the the exec bit if the corresponding read
1558 2004-05-10 Zoltan Varga <vargaz@freemail.hu>
1560 * io.c (FindFirstFile): Fix invalid free.
1562 2004-05-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1564 * io.c: translate from GFileError to errno codes and don't free
1565 variables right after calling mono_io_scandir, as we may overwrite
1568 2004-05-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1570 * io.c: g_dir_open return ENOENT for directories on which we don't have
1571 read/execute permission, while returning EPERM for anything below those.
1572 So, change ENOENT by EPERM if the directory exists.
1574 2004-05-07 Dick Porter <dick@ximian.com>
1576 * io.c (SetFileAttributes): Don't have failed chmod()s cause a
1577 "file not found" error. Fixes bug 54032.
1579 2004-05-07 Dick Porter <dick@ximian.com>
1581 * io.c (FindFirstFile): Comment out a windows-compatibility check
1582 that breaks when directories have metachars in their names.
1583 Workaround for bug 58116.
1585 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1587 * io.c: fixed for FindFirstFile for empty directories. Closes
1590 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1592 * processes.c: set the start time for the current process. Fixes bug
1595 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1597 * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
1598 * io.c: implemented scandir using glib functions.
1600 2004-05-04 Dick Porter <dick@ximian.com>
1602 * daemon.c (read_message): Return FALSE on error so the GSource
1603 callback itself can return FALSE. Cures the infinite loop poll()
1605 * shared.c: Fix some daemon startup race conditions.
1607 2004-04-29 Miguel de Icaza <miguel@ximian.com>
1609 * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k,
1610 use the stack, do not use dynamic memory.
1612 2004-04-29 Zoltan Varga <vargaz@freemail.hu>
1614 * io.c: Add scandir implementation for platforms which do not have
1617 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1619 * io.[ch]: implemented GetLogicalDriveStrings.
1621 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1624 * sockets.c: use the field name from configure when accessing sigval
1625 pointer field. Makes this work on the Mac.
1627 2004-04-28 Bernie Solomon <bernard@ugsolutions.com>
1629 * atomic.c: (InterlockedExchange) fix typo for
1632 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1635 * sockets.c: added check for sys/aio.h.
1637 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1639 * error.[ch]: added _wapi_get_win32_file_error...
1640 * io.c: ... which was _wapi_get_win32_error here.
1641 * sockets.c: rename the function calls here too.
1643 2004-04-28 Dick Porter <dick@ximian.com>
1645 * daemon-messages.c: Avoid a deadlock when a thread is killed while
1646 waiting for the daemon by using a recursive mutex. Helps bug 56699.
1648 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1650 * io.c: fixed leak in async_notifier().
1652 * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl
1655 * threads.c: removed old comment.
1657 2004-04-26 David Waite <mass@akuma.org>
1659 * daemon-messages.h:
1666 * wapi-private.h: remove comma from end of enumeration declarations
1667 * status.h: cast unsigned int types to int for enum assignment
1669 2004-04-26 David Waite <mass@akuma.org>
1672 * timefuncs.c: declare 64-bit constants as long long types (i.e.
1675 2004-04-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1677 * socket-wrappers.h: _wapi_socket == WSASocket now. Added
1678 WSA_FLAG_OVERLAPPED.
1680 * sockets.c: new unused parameters for _wapi_socket.
1682 2004-04-22 Miguel de Icaza <miguel@ximian.com>
1684 * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle
1685 the fact that MacOS X is a piece of junk (sem_init is *defined* in
1686 the libc, but they return `not implemented').
1688 2004-04-22 Dick Porter <dick@ximian.com>
1691 * handles-private.h: Reference the handle when it is locked, so
1692 that another thread can't blow it away while we're waiting for it
1693 to become signalled.
1704 * handles-private.h:
1707 * daemon-messages.c:
1708 * critical-sections.c:
1709 * atomic.c: Added pthreads cleanup handlers and error asserts
1712 * handles.c: Fixed the gcc "variable might be used uninitialised"
1713 warnings. They can't happen, but gcc doesn't know that
1714 g_assert()s don't return.
1716 Fixed the declaration of _wapi_handle_process_kill() so that it
1717 expects the correct type for the pid.
1719 * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that
1720 hasn't been used in ages and just made the code more complex.
1722 2004-04-17 Zoltan Varga <vargaz@freemail.hu>
1724 * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
1725 warnings. Fixes #57168.
1727 2004-04-16 Dick Porter <dick@ximian.com>
1729 * threads.c (Sleep): Using div(3) with a negative (when signed)
1730 numerator causes the quotient to be 0 and the remainder to be the
1731 numerator. This feeds a small negative value to nanosleep(3),
1732 which will return immediately and cause a busy wait. Fixes bug
1735 2004-04-15 Dick Porter <dick@ximian.com>
1738 * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3)
1739 and fnmatch(3) instead of glob(3). glob() can't cope with being
1740 given filenames containing metachars. This fixes bug 40557.
1742 2004-04-14 Bernie Solomon <bernard@ugsolutions.com>
1744 * security.c: #warning is a GCC-ism
1746 2004-04-13 Sebastien Pouliot <sebastien@ximian.com>
1748 * security.c: Removed GetUserName as glib g_get_user_name does a
1749 better (portability) job. Added ImpersonateLoggedOnUser and
1752 2004-04-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1754 * mono-mutex.h: move pthread_mutex_timedlock declaration to...
1755 * mono-mutex.c: ...here. It was causing a warning that prevented
1756 libgdiplus compilation.
1758 2004-04-04 Miguel de Icaza <miguel@ximian.com>
1760 * security.c (GetUserName): Make it work on MacOS X
1762 2004-04-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1764 * security.c: use getpwuid_r if available. This one is thread-safe.
1766 2004-04-02 Sebastien Pouliot <sebastien@ximian.com>
1768 * Makefile.am: Added security.c|h.
1769 * security.c: New file for security related functions. Added function
1770 GetUserName to fix #56144.
1771 * security.h: New. Header file for security.c
1772 * wapi.h: Added include for security.h
1774 2004-03-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1776 * daemon-messages.h: added kill structs.
1778 * daemon.c: implemented process_process_kill.
1779 * handles-private.h: define process_process_kill.
1780 * handles.c: implemented _wapi_handle_process_kill.
1781 * processes.[ch]: implemented TerminateProcess.
1783 2004-03-25 Bernie Solomon <bernard@ugsolutions.com>
1785 * daemon.c (rem_fd): On solaris you seem to get an
1786 error even after removing the input source so don't
1787 try and rem_fd it twice.
1789 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
1791 * daemon.c: in process_post_mortem, If the child terminated due to the
1792 receipt of a signal, the exit status must be based on WTERMSIG, since
1793 WEXITSTATUS returns 0 in this case.
1795 2004-03-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1797 * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.
1799 2004-03-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1801 * daemon.c: only call getdtablesize () once.
1802 * processes.c: wait 500 ms to check if execve failed and throw the same
1803 exception as MS on failure. Fixes bug #32809.
1805 2004-03-17 Bernie Solomon <bernard@ugsolutions.com>
1807 * io.c (async_notifier): use "union sigval" rather
1808 than sigval_t as Solaris doesn't have sigval_t
1809 (which isn't in IEEE 1003.1 either).
1811 2004-03-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1813 * io.c: added debug stuff and removed a few redundant lines in
1816 2004-03-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1818 * io-private.h: added new fields for file structure. Declare
1819 _wapi_io_add_callback.
1821 * io.c: added _wapi_get_win32_error, support aio_read/write in
1822 file_read/write. Implemented _wapi_io_add_callback, which is where
1825 * io.h: added new fields for WapiOverlapped and typedef for the
1828 * processes.c: fixed off-by-one bug when handling environment variables
1831 * threads.[ch]: implemented BindIoCompletionCallback.
1833 * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE.
1835 2004-03-14 Zoltan Varga <vargaz@freemail.hu>
1837 * socket-wrappers.h: Remove extra semicolon.
1839 2004-03-03 Dave Camp <dave@ximian.com>
1841 * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
1842 Use a new main context.
1844 2004-03-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1847 (GetFileAttributes): set the error depending on errno instead of
1848 setting ERROR_FILE_NOT_FOUND always. See bug #55160.
1850 2004-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1853 (CopyFile): free the buffer on error.
1855 (WSAIoctl): free the buffer on error.
1857 2004-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1859 * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT.
1861 * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW
1862 using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style.
1864 2004-01-27 Bernie Solomon <bernard@ugsolutions.com>
1866 * shared.c (_wapi_shm_file): add hostname
1867 to shared data file names to handle NFS mounted
1870 Mon Jan 26 16:15:03 CET 2004 Paolo Molaro <lupus@ximian.com>
1872 * sockets.h: remove obsolete soklen_t typedef.
1874 Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>
1876 * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket
1877 wrappers to its own non-installed header file.
1879 2004-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1882 (FindFirstFile): unlock the handle if FindNextFile fails.
1883 (FindNextFile): g_free a couple of pointers before retrying.
1886 (WaitForMultipleObjects): if only one handle provided, use
1887 WaitForSingleObject.
1889 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
1891 * handles-private.h: (_wapi_handle_type) check
1892 for segment in range before using it
1894 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
1896 * thread-private.h: _wapi_thread_ops is now const
1899 Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>
1901 * threads.c, timed-thread.c, timed-thread.h: use mach
1902 semaphores on Darwin (MacOSX) since the posix ones
1903 are mostly broken there (threads are not created suspended
1904 and they can start executing before they are fully initialized
1905 like in tests/thread-static.cs).
1907 Mon Dec 22 17:18:45 CET 2003 Paolo Molaro <lupus@ximian.com>
1909 * atomic.h: ppc fixes.
1911 2003-12-19 Bernie Solomon <bernard@ugsolutions.com>
1913 * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
1916 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
1918 * shared.c: (_wapi_shm_open) make scratch file
1919 not have to immediately regrow to avoid remaps
1920 (HPUX can't cope with these).
1921 (_wapi_shm_attach) use actual size of file
1922 to set scratch data_len for the creating process.
1924 * handles.c: (_wapi_handle_new_internal) make
1925 sure mutex & cond var are initialized even for
1926 non process shared ones.
1927 (_wapi_handle_unref) always call destroy
1928 routines on mutex & cond var
1930 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
1932 * daemon.c: change channel data structure so
1933 input sources are removed from glib event loop
1934 properly. xsp works better on Solaris and
1937 2003-12-12 Bernie Solomon <bernard@ugsolutions.com>
1939 * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
1940 definition with file & line number for non-GCC
1943 2003-12-08 Bernie Solomon <bernard@ugsolutions.com>
1945 * Makefile.am: make sure hppa_atomic.s is in distribution
1947 2003-12-01 Dick Porter <dick@ximian.com>
1950 * mutexes.c (CreateMutex):
1951 * mutex-private.h (struct _WapiHandle_mutex):
1952 * handles.c: Look up certain handle types by name, in a shared
1953 namespace. Currently only mutex handles have this implemented.
1956 * semaphores.c (CreateSemaphore):
1957 * events.c (CreateEvent): Fix signature
1959 2003-11-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1961 * io.c: don't call g_free before testing errno as it may modify it.
1962 If the path exists, return an error if it's not a directory. Fixes
1965 2003-11-20 Dick Porter <dick@ximian.com>
1967 * io.c: Missed a little-endian UTF16 conversion. Patch from
1968 Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.
1970 2003-10-29 Dick Porter <dick@ximian.com>
1972 * io.c (MoveFile): If the move crosses filesystems, try and fall
1973 back to copy and delete. Patch from Jörg Rosenkranz
1974 (JoergR@voelcker.com), fixes bug 50298.
1976 2003-10-28 Dick Porter <dick@ximian.com>
1978 * io.c: Use the new encoding conversion to cope with non-utf8
1979 locales in filenames.
1981 * processes.c: Ditto for process arguments.
1983 Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro <lupus@ximian.com>
1985 * atomic.h: some ppc inline asm fixes (incorrect use of labels,
1986 incorrect register constraints, incorrect clobber lists).
1988 2003-10-13 Bernie Solomon <bernard@ugsolutions.com>
1990 * Makefile.am hppa_atomic.s: add HP 64bit
1991 implementation of atomic ops
1993 2003-10-13 Zoltan Varga <vargaz@freemail.hu>
1995 * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
1996 a conditional for platforms that don't have it.
1998 2003-10-09 Bernie Solomon <bernard@ugsolutions.com>
2000 * threads.c: (CreateThread) use stacksize argument
2001 if non-zero - change default for 64 bits to 4Mb
2003 2003-09-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2005 * sockets.c: set last error when socket creation fails. This shed some
2006 light on bug #49015.
2008 2003-09-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2010 * processes.c: fixed bug #48973: we only change \ by / for the argument
2011 to be used as command.
2012 When getting the program name from the args, don't let the space between
2015 2003-09-24 Bernie Solomon <bernard@ugsolutions.com>
2017 * atomic.h atomic.c: fix sparc so lock is
2018 global, increment does so and it compiles under Sun compiler.
2020 2003-09-22 Bernie Solomon <bernard@ugsolutions.com>
2022 * handles.c: include <string.h> directly as may
2023 not be nested in <sys/un.h> like Linux
2025 2003-09-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2028 (DeleteFile): call SetLastError on failure. Fix by
2029 richard.torkar@htu.se (Richard Torkar). Closes bug #48222.
2031 2003-09-15 Lluis Sanchez Gual <lluis@ximian.com>
2033 * daemon.c: In compare_process(), discard handles already signalled.
2035 2003-09-02 Dick Porter <dick@ximian.com>
2037 * io.c: Work around glib brain-dead assumptions about utf8-encoded
2038 filenames. Fixes bug 30781.
2040 2003-08-28 Dick Porter <dick@ximian.com>
2042 * critical-sections.c: Patch from Bernie Solomon
2043 <bernard@ugsolutions.com> to emit a warning if locking a critical
2046 2003-07-23 Dick Porter <dick@ximian.com>
2049 * daemon.c (maybe_exit): Avoid the race condition when the daemon is
2050 closing but another client comes along when the shared data is still
2051 visible. Should fix bugs 33671 and 35213.
2053 2003-07-23 Dick Porter <dick@ximian.com>
2055 * handles.c: Initialise handle mutex and cond. Fix by
2056 Bernie Solomon <bernard@ugsolutions.com>
2058 2003-07-15 Dick Porter <dick@ximian.com>
2060 * timed-thread.c (timed_thread_start_routine): Fix virtual memory
2061 leak when threads quit. Fixes bug 44067.
2063 Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro <lupus@ximian.com>
2065 * io.c: never add write permission for group or others in
2066 SetFileAttributes ().
2068 2003-06-17 Dick Porter <dick@ximian.com>
2070 * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
2071 ignore the unsupported ones ("fixes" bug 44977).
2073 2003-06-17 Lluis Sanchez Gual <lluis@ximian.com>
2075 * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for
2076 high ms values (there was an overflow).
2078 2003-06-17 Zoltan Varga <vargaz@freemail.hu>
2080 * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.
2082 2003-06-11 Dick Porter <dick@ximian.com>
2084 * shared.c: Fix shared directory creation. Patch from
2085 Pablo Baena <pbaena@uol.com.ar>
2087 2003-06-10 Dick Porter <dick@ximian.com>
2089 * atomic.c: Delete the useless compile warning
2091 2003-06-09 Dick Porter <dick@ximian.com>
2093 * daemon.c: Lookup env as a string array. Fixes bug 44289. Also
2094 make setting the process handle value in the environment actually
2097 * processes.c: Pretty up the process name, if it happens to be
2098 "mono" such as when another mono process forks "mono foo.exe"
2100 2003-06-05 Dick Porter <dick@ximian.com>
2102 * processes.c (process_set_current): Don't do an expensive handle
2103 search at application startup, check the environment to see if the
2104 process handle has already been created.
2106 * io.c: Don't do an expensive handle search when creating stdin,
2107 stdout and stderr handles, just create them all the first time one
2114 * handles-private.h:
2115 * daemon-messages.h:
2117 * daemon.c: Support for "unlimited" number of handles and scratch
2120 Speed up application startup by passing process handle in the
2121 environment, rather than let the app scan all handles (which gets
2122 really slow when there are more than a few thousand to check.)
2124 Initialise some structs passed to syscalls, noticed by valgrind.
2127 2003-05-20 Dick Porter <dick@ximian.com>
2129 * io.c (FindFirstFile): Include . files in the glob. Fixes bug
2132 2003-05-19 Dick Porter <dick@ximian.com>
2134 * threads.c: Set the new thread's stack size to 2M. Fix needed
2135 for BSD, reported by Martin Dvorak <md@9ll.cz>
2137 2003-05-16 Dick Porter <dick@ximian.com>
2140 * io.c: Implement GetTempPath()
2142 2003-05-16 Dick Porter <dick@ximian.com>
2144 * processes.c (CreateProcess): Set some error codes
2146 2003-05-12 Dick Porter <dick@ximian.com>
2148 * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
2149 Patch from Martin Dvorak <mdvorak@ninell.cz>.
2151 2003-05-10 Dick Porter <dick@ximian.com>
2153 * io.c (CopyFile): Copy file mode as well as file data. Based on
2154 suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
2157 2003-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2159 * handles.c: don't call GC_gcollect when creating new handles.
2161 2003-05-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2163 * handles.c: added some debugging code. Call GC_gcollect
2164 before creating a new handle. It makes Lupus' test run smoother and
2165 faster (from 62 to 83 request per second). Notice that calling
2166 GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does
2167 not improve nor degrade the performance, so i don't do it.
2169 2003-05-02 Dick Porter <dick@ximian.com>
2171 * sockets.c: Rearrange closesocket() and socket_close_private(),
2172 and remember to unref the handle, so we don't leak socket handles.
2173 Fix from Pelle Johnsen <pelle.johnsen@mail.dk>
2175 2003-04-11 Dick Porter <dick@ximian.com>
2177 * atomic.h: ARM atomic operations by Malte Hildingson
2178 <tds00mahi@tellus.thn.htu.se>
2180 Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>
2182 * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.
2184 2003-04-03 Martin Baulig <martin@ximian.com>
2186 The following change is conditional to `WITH_INCLUDED_LIBGC'
2187 which is not yet enabled by default.
2189 * threads.c (SuspendThread, ResumeThread): Fully implemented this.
2190 (gc_init): New static function; install a signal handler for
2191 SIGPWR which is used to suspend threads. [FIXME: it SIGPWR
2192 doesn't exist on all Unix systems, we need to find another
2194 (mono_wapi_push_thread_stack): New public function. Tells the
2195 garbage collector about the current stack pointer of a suspended
2198 2003-04-03 Martin Baulig <martin@ximian.com>
2200 * timed-thread.h (TimedThread): Added `suspended_sem',
2201 `suspend_count' and `stack_ptr'.
2203 2003-03-28 Dick Porter <dick@ximian.com>
2205 * atomic.h: PPC support gratiously donated to the public domain
2206 by John Duncan <jddst19@mac.com>
2208 2003-03-20 Dick Porter <dick@ximian.com>
2210 * sockets.c (_wapi_connect): If connect() fails with EACCES, try
2211 setting SO_BROADCAST and connecting again. Fixes bug 39178.
2213 2003-03-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2215 * processes.c: included Jerome Laban's patch and call SetLastError when
2216 the executable is not found.
2218 2003-03-03 Dick Porter <dick@ximian.com>
2220 * io.c (CreateFile): Try opening directories readonly, so that
2221 timestamps can be adjusted. Patch by Elan Feingold
2222 <efeingold@mn.rr.com>.
2224 2003-02-25 Dick Porter <dick@ximian.com>
2226 * shared.c (_wapi_shm_attach): Return a failure code on system
2227 call errors, rather than exiting.
2229 2003-02-21 Dick Porter <dick@ximian.com>
2231 * processes.c (GetCurrentProcessId): Use the current process
2232 handle to return the process ID, as getpid() is unreliable
2233 (linuxthreads gives each thread a different pid). Fixes bug
2236 2003-02-21 Dick Porter <dick@ximian.com>
2238 * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug
2241 2003-02-11 Dick Porter <dick@ximian.com>
2244 * timefuncs.c: Added GetTickCount()
2246 2003-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2248 * error.c: added WSA_EHOSTUNREACH mapping.
2250 2003-01-26 Miguel de Icaza <miguel@ximian.com>
2252 * io.c (SetFileAttributes): This routine is not currently
2253 implemented for the general case, but I added a special case to
2254 set the executable bit on Linux.
2256 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
2258 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
2260 2003-01-08 Dick Porter <dick@ximian.com>
2262 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
2264 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
2266 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2267 Check for an implementation which says it supports
2268 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
2269 defines the symbol. Defined but with a value of -1 still
2270 means that it is unsupported.
2272 2002-12-08 Martin Baulig <martin@ximian.com>
2274 * handles.c (_wapi_handle_new): Create new non-shared handles with
2275 an initial refcount of 1, not 0.
2277 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
2279 * threads.c (TlsGetValue): removed unnecessary mutex
2281 2002-11-20 Dick Porter <dick@ximian.com>
2283 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
2284 need to store their data structure too.
2286 * threads.c: Make sure the threading data is initialised wherever
2289 2002-11-15 Dick Porter <dick@ximian.com>
2291 * timed-thread.c: Removed unneeded parameters in
2292 _wapi_timed_thread_attach().
2294 * threads.c: Renamed AttachThread() to make it not look like
2295 external API. Removed unneeded parameters.
2297 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2299 * error.[ch]: added errno_to_WSA (). It displays a warning and return
2300 WSASYSCALLFAILURE if there is no error mapping for the given errno,
2302 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
2304 2002-10-31 Dick Porter <dick@ximian.com>
2307 * io.c: Define and use INVALID_FILE_ATTRIBUTES
2309 2002-10-07 Dick Porter <dick@ximian.com>
2312 * daemon.c: Use a more accurate time source for process start and
2315 2002-10-03 Dick Porter <dick@ximian.com>
2319 * threads.c: Fixes for freebsd. Make sure that mutex and condition
2320 creation and deletion happen in the process that owns them, when
2321 POSIX shared thread objects aren't supported. This breaks on
2322 freebsd, as pthread_t is a pointer to data.
2324 2002-10-02 Dick Porter <dick@ximian.com>
2326 * shared.c: Use mmap() instead of sysv shm for the shared data.
2328 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
2332 * daemon.c: mmap()ed regions survive fork, so just pass the
2333 pointer to _wapi_daemon_main instead of mapping it again.
2335 2002-10-01 Dick Porter <dick@ximian.com>
2337 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
2338 Unfortunately libgc uses the same thread suspend technique that I
2339 want to, and the two don't mix: libgc will deadlock when it tries
2340 to stop the world if a thread has already been suspended by
2341 someone else. Just do the simple suspended create rather than the
2342 general purpose thread suspension for now.
2344 * threads.c: Pass create flags to the timed_thread create call, to
2345 implement suspended thread creation. ResumeThread() partially
2346 implemented, to cope with the case where a newly created but
2347 suspended thread is launched.
2349 2002-09-30 Dick Porter <dick@ximian.com>
2351 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
2354 2002-09-27 Dick Porter <dick@ximian.com>
2356 * semaphores.c: Only include semaphore.h if it's present. Patch
2357 for BSD from jmmv@hispabsd.org (Julio Merino).
2359 2002-09-27 Dick Porter <dick@ximian.com>
2361 * processes.c: Pass environment and working directory to the
2362 daemon when forking. Don't let argv[0] be duplicated when looking
2363 for the program name. Implement EnumProcessModules (simple
2364 version for now, lsof-style later if needed), GetModuleBaseName,
2365 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
2366 aren't available on Linux).
2368 * process-private.h: Store the process name, and the working set
2372 * handles-private.h: New functions to store and retrieve an array
2373 of strings in the scratch space
2375 * daemon.c: Don't miss deleting some handles when a client exits
2376 (we used to rely on the client doing the final cleanup, but
2377 obviously if the client is no longer there the daemon has to do
2380 Process forking now sets the environment and the working
2383 * io.c: Don't confuse fd 0 with an unassigned handle struct
2385 * atomic.h: Add a google cache alternative to the msdn URL
2387 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2390 (_wapi_recvfrom): added ECONNRESET to the switch.
2392 2002-09-24 Mark Crichton <crichton@gimp.org>
2394 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
2397 2002-09-19 Mark Crichton <crichton@gimp.org>
2399 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
2400 dont have Linux's abstract filesystem for sockets.
2402 2002-09-19 Mark Crichton <crichton@gimp.org>
2404 * atomic.h: Added SPARC atomic asm code.
2405 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2406 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
2407 Solaris 9, however, the code paths don't seem to work. More testing
2408 on the shared case is *really* needed.
2410 2002-09-03 Dick Porter <dick@ximian.com>
2413 * threads.c: Removed PosixKillThread(), because it's not in the
2416 2002-08-20 Dick Porter <dick@ximian.com>
2418 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
2419 multiples of 4 bytes, to keep header structures aligned. Needed
2420 for sparc, at least. (Patch from crichton@gimp.org)
2422 * handles.c: Removed 'disable_shm' variable (we've defaulted to
2423 building with shm enabled for months now)
2425 2002-08-19 Dick Porter <dick@ximian.com>
2427 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
2428 for legacy NeXT-based systems.
2430 2002-08-12 Dick Porter <dick@ximian.com>
2432 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
2433 from Joseph Wenninger <kde@jowenn.at>)
2435 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
2437 * threads.c: use fast spinlocks by default
2439 2002-08-02 Dick Porter <dick@ximian.com>
2441 * io.c (GetStdHandle): Add a handle reference when returning a
2442 duplicate console handle. This fixes the unref_handle errors in
2445 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
2447 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
2450 2002-08-01 Dick Porter <dick@ximian.com>
2452 * threads.c: Use atomic spinlocks in TLS functions
2455 * Makefile.am: Added mono-spinlock.h
2457 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
2459 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
2460 these are needed for sendmsg() and also for struct msghdr (at
2461 least on Solaris). Solaris still won't build because struct msghdr
2462 doesn't have msg_flags, msg_control, or msg_controllen members.
2463 (CMSG_SPACE): Define for systems that don't have it.
2466 2002-07-20 Dick Porter <dick@ximian.com>
2472 * handles.c: Implemented pipe handles
2475 * daemon.c: Fixed bug in handle closing.
2478 * daemon.c: Forked processes now close all open file descriptors.
2480 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
2482 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
2485 2002-07-19 Martin Baulig <martin@gnome.org>
2487 * threads.c (ExitThread): Call exit() if no threads has been
2490 2002-07-17 Dick Porter <dick@ximian.com>
2492 * daemon-messages.c: Freebsd fixes from Andreas Kohn
2493 <andreas.kohn@gmx.net>
2495 2002-07-15 Dick Porter <dick@ximian.com>
2497 * io.c: Removed bogus console_flush() method, that was just cut
2498 and pasted from file_flush when I separated the two handle types.
2500 2002-07-12 Dick Porter <dick@ximian.com>
2502 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
2503 flags. Fixes bug 27633.
2505 2002-07-12 Dick Porter <dick@ximian.com>
2509 * daemon.c: Use size of sockaddr_un.sun_path from config.h
2511 2002-07-12 Dick Porter <dick@ximian.com>
2513 * processes.c (CreateProcess): Send stdin, stdout and stderr
2514 handles if the startup info doesnt specify new ones
2516 * io.c (GetStdHandle): Return the same handle when the same
2517 standard handle is requested
2519 * handles.c: Pass file descriptors when forking
2521 * daemon.c: Use supplied file descriptors when forking a new
2524 * daemon-messages.h:
2525 * daemon-messages.c: Pass stdin, stdout and stderr file
2526 descriptors to the daemon (used when forking)
2528 2002-07-11 Miguel de Icaza <miguel@ximian.com>
2530 * daemon.c (_wapi_daemon_main): Use sizeof
2531 (main_socket_address.sun_path) instead of hardcoded 108 value.
2533 * handles.c (shared_init): Use sizeof
2534 (shared_socket_address.sun_path) instead of hardcoded 108 value.
2536 2002-07-10 Dennis Haney <davh@davh.dk>
2540 * daemon.c: Lots of documentation, some added error checking, and
2541 code readability improvements.
2543 * daemon-messages.h: Add the Error request type to improve error
2546 * daemon-messages.c: Do a bit more error checking on send() and
2547 recv(), and log errors with a higher severity level.
2549 2002-07-04 Dick Porter <dick@ximian.com>
2551 * daemon.c (process_process_fork): Fix argument handling, due to
2552 buggy understanding of g_strsplit() behaviour.
2554 2002-07-03 Dick Porter <dick@ximian.com>
2557 * threads.c: Implement OpenThread(). Define access-control values
2563 * Makefile.am: Added access.h, to hold shared access-control
2566 2002-07-02 Dick Porter <dick@ximian.com>
2568 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
2570 2002-07-02 Dick Porter <dick@ximian.com>
2572 * handles.c (shared_init): Make a second attempt to contact the
2573 daemon if the shared memory attach succeeds, but the connect()
2574 fails. (This copes with the daemon crashing without cleaning up
2580 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
2581 the daemon, it's now built into the library.
2583 2002-06-25 Dick Porter <dick@ximian.com>
2586 * handles-private.h:
2587 * daemon-messages.h:
2588 * daemon.c: Process forking and handle data management
2591 * process-private.h:
2592 * processes.c: Process forking and other support functions
2594 2002-06-25 Dick Porter <dick@ximian.com>
2596 * versioninfo.h: PE resource decoding
2598 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
2599 to be told the string length
2601 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
2602 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
2605 2002-06-12 Dick Porter <dick@ximian.com>
2608 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
2609 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
2610 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
2612 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
2614 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
2615 when writing to a closed socket.
2617 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
2619 * mono-mutex.c (mono_once): New convenience function for my
2624 * critical-sections.c:
2632 * atomic.c: Use mono_once() rather than pthread_once().
2634 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
2636 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
2637 if multiple threads all try to call _wapi_handle_new() before the
2638 shared data has been initialized, it is possible that we could get
2639 into a condition where shared_init() is being executed and later
2640 threads will pass by pthread_once() due to the fact that it has
2641 already been called and so therefor will attempt to use the shared
2642 data before it has been completely initialized. If we instead use
2643 a standard mutex locking mechanism around shared_init(), we can
2644 avoid the situation entirely. By wrapping the mutex locking in a
2645 check to see if we've already initialized the data, we can even
2646 avoid wasting resources by having to lock/unlock the mutex in any
2647 later calls (the only time we'd have to worry about
2648 locking/unlocking is the initial race to call shared_init() at
2651 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
2653 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
2655 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
2657 * daemon.c, handles.c: rename "sun" local var since it's apparently
2658 a #define on Solaris.
2660 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
2662 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
2665 2002-05-15 Dick Porter <dick@ximian.com>
2667 * wait.c: Fix a deadlock in WaitForMultipleObjects
2669 2002-05-14 Dick Porter <dick@ximian.com>
2671 * io.c: Fix a cut&paste error, found by
2672 Jaroslaw Kowalski <jarek@atm.com.pl>
2674 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
2678 2002-05-09 Dick Porter <dick@ximian.com>
2684 * handles-private.h:
2686 * Makefile.am: Remove now-unused file wait-private.h
2688 2002-05-08 Dick Porter <dick@ximian.com>
2690 * shared.c: Better error messages, and report when daemon
2691 connection fails rather than blocking forever. Do some more
2692 shared memory sanity checking.
2694 * handles.c: Better error messages when connecting to shared
2695 memory and the handle daemon. Fall back to non-shared handles if
2696 an error occurs. Set the default back to 'shared handles'. Fix a
2697 crashing bug in scratch space allocation that mangled the block
2700 2002-05-07 Miguel de Icaza <miguel@ximian.com>
2702 * handles.c (shared_init): Disable SHM for now, people have too
2703 many problems with this, and the diagnostics are not helping.
2705 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
2707 * io.c: CreateFile sets win32 last error.
2709 2002-05-05 Dick Porter <dick@ximian.com>
2712 * handles-private.h:
2718 * process-private.h:
2720 * semaphore-private.h:
2724 * event-private.h: Simplify the WapiHandleOps struct: take out all
2725 the file-specific entries, leaving just the items that operate on
2726 handles themselves. Split the close operation into shared and
2727 private parts: shared close is called by the daemon.
2729 * handles.c: As above, but also pass handle allocation, ref and
2730 unref operations to the daemon. Populate the handle_ops array at
2731 compile time, because the daemon needs to call ops on handles too.
2732 Don't bother to track open handle counts any more, the daemon does
2736 * thread-private.h: As above, but also make the thread data
2739 * shared.c: Fork a handle daemon if the calling process created
2740 the shared memory segment.
2743 * daemon-messages.c:
2744 * daemon-messages.h:
2745 * Makefile.am: Build a daemon to manage handle allocation and
2746 destruction without needing to lock the shared memory
2748 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
2750 * atomic.c: Changed to use a normal mutex rather than a spinlock
2751 since a lot of platforms seem to not have them :\
2753 2002-04-30 Dick Porter <dick@ximian.com>
2755 * Completely rewrote the handle waiting code: removed the helper
2756 thread and its attendant complexity. All handle waiting is now
2757 abstracted into the WaitForSingleObject() and
2758 WaitForMultipleObjects() functions.
2760 * Implemented inter-process sharing of handles using sysv shared
2761 memory. This makes handles even more opaque, with a handle now
2762 just an index into an array.
2764 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
2766 * io.c: unitialized pointer in GetCurrentDirectory.
2768 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
2770 * threads.c: destroy the mutex at thread destruction
2771 (if/when thread destruction code will be actually called).
2772 When protecting a tls data pointer from the gc, use also the
2773 thread id in the key.
2775 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
2777 * timed-thread.c: avoid race condition when setting the thread to
2780 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2782 * jit.h: to more #include lines to avoid breaking compilation
2783 under windows when upgrading mingw and w32api to version
2786 2002-04-16 Dick Porter <dick@ximian.com>
2788 * atomic.h: Explanatory comment about lack of 80386 support
2790 2002-04-15 Dick Porter <dick@ximian.com>
2792 * atomic.h: use xaddl for InterlockedIncrement() and
2793 InterlockedDecrement(). Use cmpxchgl in a loop for
2794 InterlockedExchange() and InterlockedExchangePointer().
2796 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
2798 * unicode.c: fix unicode_len() to not access uninitialized memory
2799 (and updated to conform to mono code style).
2801 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
2803 * io.c: EEXISTS is ignored for directory creation.
2804 * mono-mutex.h: remove silly "pragma }" that emacs users insert
2805 because they use a broken editor:-)
2807 2002-03-28 Dick Porter <dick@ximian.com>
2813 * handles.c: Warning cleanups
2815 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
2817 * unicode.h, unicode.c: changed to gunichar2
2818 * io.h, io.c: changed strings to gunichar2*, added
2819 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
2820 some fixes to FindFirstFile() and friends.

2834 * system.c: Beginnings of GetSystemInfo()
2836 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
2840 * context.c: Dummy function that doesnt yet implement
2844 * atomic.c: Interlocked functions
2846 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
2848 * threads.c: use a gc-safe hash table to store tls pointers.
2850 2002-03-22 Dick Porter <dick@ximian.com>
2852 * threads.c: Fix a race condition where a thread can start and
2853 exit before the handle has been properly initialised (no reason
2854 why the handle couldn't be initialised beforehand, so do so)
2856 Fix a ms to ns conversion magnitude thinko.
2858 2002-03-21 Dick Porter <dick@ximian.com>
2860 * semaphores.c: Fix a problem when waiting for one or more
2861 semaphores, and another semaphore is Released (all waiting
2862 semaphores assumed they were signalled)

2866 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
2867 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
2869 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
2871 * threads.c (Sleep): bug fix: 1ms == 1000000ns
2873 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
2875 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
2876 threads.c, io.c: added flush method to handles.

2910 arguments for the sake of portability. Implements recursive
2911 mutexes and pthread_mutex_timedlock.
2913 * critical-sections.c:
2920 * wait.c: Use the mono-mutex wrapper portability functions/macros.
2922 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
2924 2002-01-23 Dick Porter <dick@ximian.com>
