46 2007-10-26 Dick Porter <dick@ximian.com>
48 * shared.c (_wapi_shm_file_open): Set the umask when opening
49 shared files, so restrictive defaults don't prevent subsequent
50 processes re-opening them.
52 2007-10-18 Zoltan Varga <vargaz@gmail.com>
54 * atomic.h (InterlockedCompareExchange): Fix the ia64 version so it works for
55 negative values too. Hopefully fixes #332700.
57 2007-09-26 Dick Porter <dick@ximian.com>
59 * io-portability.c (_wapi_io_scandir): Only update the error
60 status of glob() when performing a secondary glob() if the first
61 returned an error. Fixes bug 325107.
63 2007-09-12 Marek Habersack <mhabersack@novell.com>
65 * io-portability.c: options_init moved to
66 utils/mono-io-portability.c

89 2007-09-03 Atsushi Enomoto <atsushi@ximian.com>
91 * processes.h : removed extra parameters from CreateProcessWithLogonW.
93 2007-09-03 Atsushi Enomoto <atsushi@ximian.com>
95 * processes.c, processes.h: added CreateProcessWithLogonW(). For now
96 it just calls CreateProcess().
97 * io-layer.h : CreateProcessWithLogonW() requires WINVER 0x0500
100 2007-08-23 Robert Jordan <robertj@gmx.net>
102 * processes.[c|h]: Implement Get|SetPriorityClass ().
103 Code is contributed under MIT/X11 license.

124 * processes.c: implemented query for user/system times using
127 2007-08-10 Dick Porter <dick@ximian.com>
129 * sockets.c (_wapi_getsockopt, _wapi_setsockopt): Check the option
130 level as well as the name when mangling some of the values. Fixes
133 2007-08-02 Dick Porter <dick@ximian.com>
135 * sockets.c: Changes in error handling, and move the SO_REUSEADDR
136 setting from metadata/socket-io.c.
138 2007-08-01 Dick Porter <dick@ximian.com>
140 * io-portability.c (_wapi_io_scandir): Special-case patterns
141 ending in '.*' so that files with no extension are also matched.
145 * wapi_glob.c: Reinstate WAPI_GLOB_APPEND, and add
146 WAPI_GLOB_UNIQUE to avoid matching the same entry twice when
149 2007-07-26 Dick Porter <dick@ximian.com>
154 * critical-sections.c:
156 * critical-section-private.h:

176 Fri Jul 13 12:46:15 CEST 2007 Paolo Molaro <lupus@ximian.com>
178 * handles-private.h, handles.c, thread-private.h, threads.c,
179 uglify.h, wait.c: temporarily revert the alertable wait changes
180 (r79386) until the deadlock issues are fixed.
182 2007-06-22 Dick Porter <dick@ximian.com>
184 * shared.c: The non-shared mutexes weren't being initialised properly

187 2007-06-13 Randolph Chung <tausq@debian.org>
189 * atomic.h: Enable for all hppa targets.
190 * Makefile.am: rename hppa_atomic.s to hppa_atomic.S so the preprocessor
192 * hppa_atomic.s: Renamed to ...
193 * hppa_atomic.S: ... and updated to work on both HPUX and Linux.
195 2007-06-13 Dick Porter <dick@ximian.com>
197 * handles.c (timedwait_signal_wait_cond): Alertable waits on
198 private handles are now interrupted by signalling the same
199 condition that would end the wait if the handle became signalled,
200 rather than polling. (Shared handles still have to poll.)
202 * threads.c (_wapi_thread_queue_apc): Interrupt the thread if it's
205 * handles-private.h (_wapi_handle_current_thread_set_waiting_on):
206 Helper functions to inform the APC queuing functions when threads
207 are waiting for handles, and to interrupt the wait.
209 * wait.c (WaitForMultipleObjectsEx): Need to tell the handle
210 waiting functions if any of the handles in question are shared
212 2007-06-06 Miguel de Icaza <miguel@novell.com>

216 2007-06-06 Wade Berrier <wberrier@novell.com>
218 * atomic.h (InterlockedExchangePointer): cast to pointer to to silence
219 compiler warnings (autobuild fails the build on this type of warning)
221 2007-05-21 Dick Porter <dick@ximian.com>
223 * io-portability.c (_wapi_g_dir_open): Don't propagate any errors
224 from the second call to g_dir_open, preserve the original error if
225 the second call still fails but clear the error if it succeeds.
227 2007-05-10 Dick Porter <dick@ximian.com>
229 * sockets.c (_wapi_recvfrom): Refine the fix to bug 75705 so EINTR
230 isn't returned if the remote end shuts down cleanly. Fixes zmd
231 and the second example in bug 75705.
233 2007-04-26 Dick Porter <dick@ximian.com>
235 * shared.c (_wapi_shm_semaphores_init): Need to check
236 MONO_DISABLE_SHM in this entry point, as it's called before
237 _wapi_shm_attach(). Fixes bug 81436.
239 2007-04-24 Dick Porter <dick@ximian.com>
241 * sockets.c (_wapi_recvfrom, socket_close): Force recvfrom() to
242 error if the socket is closed while the receive is blocking.
245 2007-04-13 Dick Porter <dick@ximian.com>
248 * shared.c: Complete the reimplementation of disabling of shared
249 memory, by not allocating sysv semaphores when shm disabling has
250 been requested (either at compile time or run time.)
252 * processes.c (CreateProcess): Don't synchronize locking across
253 processes when forking, when shared memory has been disabled.
255 2007-04-06 Andreas Faerber <andreas.faerber@web.de>
258 * wapi_glob.c: remove reference to sys/cdefs.h, use glib instead.
261 2007-04-05 Dick Porter <dick@ximian.com>
264 * io-portability.c (_wapi_io_scandir): Moved from io.c, and
265 changed to use a cut-down version of glob(3) that has been
266 extended to match with case-insensitivity if needed.
269 * wapi_glob.c: Cut down implementation of glob(3), based on
272 2007-03-22 Dick Porter <dick@ximian.com>
274 * sockets.c (_wapi_connect): Do additional checks when connect(2)
275 fails, because some systems don't let it be restarted. Patch
276 based on one submitted by Robert S Wojciechowski <robertw@ssgx.com>,
279 2007-03-09 Jonathan Chambers <joncham@gmail.com>
281 * io-layer.h: Remove UNICODE and _UNICODE defines as
282 these are done by configure.in now.
284 Code is contributed under MIT/X11 license.
286 Thu Mar 8 19:42:17 CET 2007 Paolo Molaro <lupus@ximian.com>
288 * shared.c: partial support for MONO_DISABLE_SHM env var.
290 2007-03-05 Wade Berrier <wberrier@novell.com>
292 * atomic.h: atomic fixes from Michael Matz for for s390
293 and s390x ( bnc #237611 and bxc #80892 )
295 2007-03-05 Miguel de Icaza <miguel@novell.com>
297 * io.c (CreateFile): Use FILE_ATTRIBUTE_TEMPORARY to mean 0600
298 permissions. For 80688
300 (MoveFile): Use errno_copy here, just to avoid a potential
301 errno-changing code in the future from g_free.
303 Also, ignore EXDEV errors as they are handled immediately after
304 (avoid printing out an error).
308 Mon Feb 12 15:50:24 CET 2007 Paolo Molaro <lupus@ximian.com>
310 * shared.c: exit if semaphores can't be created (bug #80616).
312 2007-02-01 Geoff Norton <gnorton@customerdna.com>
314 * collection.c: NetBSD doesn't define PTHREAD_STACK_MIN.
316 2007-01-26 Dick Porter <dick@ximian.com>
319 * sockets.c (_wapi_getsockopt): Windows seems to not reset
320 SO_ERROR values when they're read, contrary to the documentation.
321 Fixes the new issues raised in bug 79878 (example in C showing
322 winsock behaviour attached to that bug.)
324 2007-01-15 Mark Mason <mason@broadcom.com
326 * atomic.h: add locking primitives for MIPS.
328 2007-01-11 Dick Porter <dick@ximian.com>
330 * sockets.c (_wapi_connect): Don't do the SO_BROADCAST setting
331 here, do it in managed code instead.
332 (_wapi_getsockopt): SO_RCVTIMEO and SO_SNDTIMEO use struct
333 timeval, which has a microsecond field, not milliseconds.
334 (_wapi_setsockopt): ditto.
335 (_wapi_setsockopt): Halve the SO_SNDBUF and SO_RCVBUF values on
336 Linux, as the kernel doubles whatever we set.
337 (_wapi_socket): Save socket domain, type and protocol so it can be
339 (socket_disconnect): Implement socket disconnect (closing the
340 socket, but keeping the file descriptor.)
341 (wapi_disconnectex): A basic implementation of DisconnectEx().
342 (wapi_transmitfile): A very basic implementation of
344 (WSAIoctl): Implement the SIO_GET_EXTENSION_FUNCTION_POINTER
347 * socket-private.h (struct _WapiHandle_socket): Record socket
348 domain, type and protocol info so it can be duplicated later.
350 * sockets.h (WSAID_DISCONNECTEX,WSAID_TRANSMITFILE): Structures
351 and defines needed to look up the DisconnectEx() and
352 TransmitFile() functions by GUID.
354 * error.c (errno_to_WSA): Change ETIMEDOUT mapping to
355 WSAETIMEDOUT; add EDESTADDRREQ.
357 * io-layer.h: Need mswsock.h on windows now.
359 2007-01-04 Miguel de Icaza <miguel@novell.com>
361 * io-portability.c (find_file): Fix a coverity warning (scanning
364 2006-12-31 Miguel de Icaza <miguel@novell.com>
366 * io-portability.c (find_file): Do not abort if an empty filename
367 has been passed. This fixes the case where MONO_IOMAP=all would
368 assert if Directory.Exists ("") was called.
370 Mon Dec 18 14:54:37 CET 2006 Paolo Molaro <lupus@ximian.com>
372 * processes.c: moved a free on the error path.
374 Thu Dec 14 21:42:39 CET 2006 Paolo Molaro <lupus@ximian.com>
376 * processes.c: fixed a few memory leaks when executing
379 Mon Nov 27 13:12:17 GMT 2006 Paolo Molaro <lupus@ximian.com>
381 * atomic.h: fix arm compare and exchange (bug #78500).
383 2006-11-23 Dick Porter <dick@ximian.com>
385 * process-private.h (struct _WapiHandle_process): Add 'waited'
388 * processes.c (process_wait): Check the 'waited' parameter not the
389 signalled state when testing if a process has already been waited
390 for, as the child process itself may set signalled when exiting.
393 * wapi-private.h (_WAPI_HANDLE_VERSION): Bump shared data version
395 * shared.c: Now the shared data version has been incremented we
396 can set the counter semaphore initial value correctly
398 2006-11-22 Dick Porter <dick@ximian.com>
400 * processes.c (process_wait): Cope when the background process
401 reaper gets the process we were waiting for. Special case for
402 waiting for our own process to exit. Fixes bug 77736.
404 2006-11-17 Dick Porter <dick@ximian.com>
406 * processes.c: Fix const correctness and typos that caused memory
409 2006-11-17 Miguel de Icaza <miguel@novell.com>
411 * processes.c (ShellExecuteEx): Check error after CreateProcess,
412 thanks to Dick for pointing this out.
414 2006-11-16 Miguel de Icaza <miguel@novell.com>
416 * processes.c (ShellExecuteEx): If we fail to create a process in
417 ShellExecute, then try to use the xdg-open command, and if that
418 fails, try to use the gnome-open command,
420 Refactor the code so that we do not have to duplicate all this
421 code, but instead use a ucs2-aware version of the code to do
424 2006-11-13 Dick Porter <dick@ximian.com>
426 * io.c (_wapi_stat_to_file_attributes): If the file is a symlink
427 add the FILE_ATTRIBUTE_REPARSE_POINT flag. This is an attempt to
428 follow the specs for the windows symlink support, but will
429 probably have to be reworked when I have test data from a vista
430 machine. Fixes bug 79887.
432 2006-11-11 Miguel de Icaza <miguel@novell.com>
434 * handles.c (CloseHandle): Cope here with the new value
435 INVALID_HANDLE_VALUE set on handles.
437 * processes.c (CreateProcess): Initialize the value of hThread to
438 be INVALID_HANDLE_VALUE on failure, not to be NULL. Improvement
441 2006-11-09 Dick Porter <dick@ximian.com>
443 * sockets.c (_wapi_select): Do some sanity checking on the
444 fd_sets, to avoid file descriptors > FD_SETSIZE.
445 (_wapi_FD_CLR, _wapi_FD_ISSET, _wapi_FD_SET): Avoid file
446 descriptors > FD_SETSIZE.
448 2006-10-27 Dick Porter <dick@ximian.com>
450 * io.c (GetFileAttributes): Force symlinks to directories to be
451 returned as a regular file. Fixes bug 79733.
453 2006-10-18 Miguel de Icaza <miguel@novell.com>
455 * io-portability.c (find_in_dir): First string dup, then closedir.
457 2006-10-12 Dick Porter <dick@ximian.com>
459 * processes.c (_wapi_process_reap): Unref a process handle if we
460 reaped it, found by Zoltan. Fixes bug 79286.
461 (process_wait): Don't wait again if we've already waited for a
464 2006-10-11 Sergey Tikhonov <tsv@solvo.ru>
466 * atomic.h: Fix atomic decrement.
468 * mini/cpu-alpha.md: Use native long shift insts
470 * mono/mono/mini/tramp-alpha.c: Implemented
471 mono_arch_patch_delegate_trampoline method
473 * Started work on using global registers
475 * Use byte/word memory load/store insts if cpu supports it
480 2006-10-09 Zoltan Varga <vargaz@gmail.com>
482 * handles.c (timedwait_signal_poll_cond): Add an alertable parameter, and if it
483 is FALSE, avoid busy waiting.
485 * wait.c: Add an alertable parameter to the wait routines.
487 2006-10-06 Miguel de Icaza <miguel@novell.com>
489 * io-portability.c (find_file): Rename from
490 MONO_IO_PORTABILITY_HELP to MONO_IOMAP.
492 2006-10-03 Dick Porter <dick@ximian.com>
495 * io-portability.c: Optional portability helpers and wrapped
496 system calls to try to cope with windows filenames in
499 * io.c: Use the wrapped system calls
501 2006-09-01 Zoltan Varga <vargaz@gmail.com>
503 * critical-sections.h critical-sections.c: Make Enter/LeaveCriticalSection a macro
504 since they are perf critical.
506 * atomic.h: Applied patch from Jakub Boqusz <qboosh@pld-linux.org>.
507 Add atomic ops implementation for alpha.
509 2006-08-11 Dick Porter <dick@ximian.com>
511 * processes.c (_wapi_process_reap): Avoid a deadlock by setting
512 process termination details in an outer loop, not the
513 _wapi_search_handle() one.
515 2006-08-10 Dick Porter <dick@ximian.com>
517 * threads.c (_wapi_thread_queue_apc)
518 (_wapi_thread_dispatch_apc_queue): Use a process-local mutex here
519 instead of the cross process semaphore. We already check that
520 access to the APC queue is within the owning process so there's no
521 need to protect from other processes. Avoids a global deadlock
522 when a thread is aborted while it holds the handle semaphore
524 (_wapi_thread_apc_pending): Hide an annoying message which can
525 happen if a thread handle has been blown away at process shutdown
526 while it is in an alertable wait.
528 Both problems seen while shutting down monodevelop.
530 2006-07-25 Dick Porter <dick@ximian.com>
532 * shared.c (_wapi_shm_file): Remove '/' characters from the uname
533 results. Fixes bug 78917.
535 2006-07-20 Dick Porter <dick@ximian.com>
537 * threads.c (_wapi_thread_set_termination_details): Improve the
538 test for already-disposed thread handles, and hold the lock around
539 the mutex abandoning.
541 2006-07-17 Dick Porter <dick@ximian.com>
543 * processes.c (CreateProcess): Don't change directory unless a new
544 one has been specified. Fixes bug 78751.
546 2006-07-06 Dick Porter <dick@ximian.com>
548 * io.c (_wapi_stat_to_file_attributes): Do a better job at
549 figuring out the file attributes
550 (_wapi_set_last_path_error_from_errno): New helper function to
551 turn errno into w32 error codes that handles the differences
552 between file and directory errors
553 (file_setendoffile): Try turning off the extra write used to
554 extend files, because we probably don't need it on any modern
555 platform. If it is needed though, we also need to lseek the file
557 (CreateFile): Treat character-special devices as a console handle,
558 because they can't be seeked
559 (CopyFile): If fail_if_exists is set, then the destination needs
560 to be opened with O_EXCL
561 (CopyFile): If fail_if_exists is not set and the destination
562 already exists, then we should set the ERROR_ALREADY_EXISTS error
563 even though we return success
564 (stdhandle_create): STD_INPUT_HANDLES cannot be written to
565 (GetStdHandle): Rework without using mono_once, so console handles
566 can be properly closed and reopened.
567 (mono_io_scandir): Only override errno with EACCES when the
568 directory actually exists
569 (FindFirstFile): Set ERROR_FILE_NOT_FOUND when no files are
571 (FindClose): Cope with NULL handles
572 (CreateDirectory): When the target already exists, just return an
573 error. It's the caller's job to figure out what to do.
574 (SetCurrentDirectory): Cope with a NULL path
575 (RemoveDirectory, GetFileAttributes, GetFileAttributesEx,
576 SetFileAttributes, FindFirstFile, DeleteFile, MoveFile, CopyFile,
577 CreateFile): Set path error correctly
579 * handles.c (CloseHandle): Kludge to try and cope with passing a
582 * error.h: Add NO_ERROR as an alternative to ERROR_SUCCESS
584 * uglify.h: Added some more typedefs
586 2006-07-05 Dick Porter <dick@ximian.com>
588 * io.c (GetFileAttributes, GetFileAttributesEx): Cope with
589 dangling symlinks. Fixes bug 78664.
591 2006-06-23 Dick Porter <dick@ximian.com>
593 * handles.c (handle_cleanup):
594 * threads.c: Clean up threads properly when we're forcibly
595 removing the handle entries from the shared file in
596 handle_cleanup(). Fixes bug 78241, for real this time.
598 2006-06-15 Neale Ferguson <neale@sinenomine.net>
600 * atomic.h: More tinkering with InterlockedExchange/InterlockedCompareExchange
603 2006-06-14 Neale Ferguson <neale@sinenomine.net>
605 * atomic.h: Fix atomic exchange pointer operations for s390x - these
606 were broken as they used 32-bit instructions rather than their 64-bit
609 2006-06-14 Dick Porter <dick@ximian.com>
611 * processes.c: Don't run the atexit handlers when bailing out
614 2006-06-14 Dick Porter <dick@ximian.com>
616 * wait.c: Fix stupid typo shown up by gcc 4.1.1, = not ==
624 * collection.c: Fix a bunch of signed/unsigned warnings from gcc
627 2006-06-09 Neale Ferguson <neale@sinenomine.net>
629 * atomic.h: Fix atomic operations for s390x (not really broken
630 but changed to use full 64-bit opcodes).
632 2006-05-24 Dick Porter <dick@ximian.com>
634 * processes.c (process_set_current): Don't take an extra reference
635 if we have to create our own process handle. Fixes bug 78241
638 * threads.c (_wapi_thread_signal_self): Renamed from
639 _wapi_thread_abandon_mutexes, also sets the thread state to
640 signalled and drops a reference. Called by the runtime when the
641 main thread cleans itself up.
643 * handles.c (handle_cleanup): As a last resort, unref every shared
644 handle as the process is now exiting.
646 2006-05-16 Dick Porter <dick@ximian.com>
648 * processes.c (process_set_termination_details): Unref the handle
649 when we've stored the exit details. Fixes the rest of 78241.
651 2006-05-12 Dick Porter <dick@ximian.com>
653 * threads.c: Implement pseudo handles, making GetCurrentThread()
654 match MS behaviour. Notice when attached threads exit, and unref
655 the handle. Fix usage of GetCurrentThread() in other places.
657 * handles.c (DuplicateHandle): Implement a basic form of
660 * wait.c: Fix usage of GetCurrentThread() throughout, and cope
663 2006-04-26 Miguel de Icaza <miguel@novell.com>
665 * io.c (file_close): Oops, do not use DeleteFile which expects
666 unicode, instead use unlink directly
668 Add support for the new FileOptions bits on .NET 2.0.
670 It might be good if Dick reviews these changes.
672 * io.c (file_close): If DeleteOnClose is set, then delete the file
674 (CreateFile): Do not support encryption per user.
676 If posix_fadvise exists, pass hints on sequential scan and random
677 access. Did not figure out what WRITE_THROUGH maps to.
679 2006-04-26 Dick Porter <dick@ximian.com>
681 * sockets.c (WSAIoctl): Check the output buffer is valid before
684 * handles.c (_wapi_search_handle): Set shared pointer if we find a
685 shared handle that has been already opened.
687 2006-04-21 Dick Porter <dick@ximian.com>
689 * threads.c (GetCurrentThread): Reference the handle if we return
690 an already-known thread.
692 2006-04-07 Dick Porter <dick@ximian.com>
694 * processes.c: Fix build for older glib.
696 2006-04-06 Dick Porter <dick@ximian.com>
698 * processes.c (CreateProcess): Add a reference to the child
699 process' handle, so it won't be destroyed if this process closes
700 its copy of the handle. Fixes bug 77393.
702 * processes.c (process_set_current): Fall through to creating a
703 new one if the handle lookup fails.
705 * processes.c (_wapi_process_signal_self):
706 * handles.c (handle_cleanup): The process is exiting, so set the
707 handle state for this process to signalled. This should let other
708 non-related processes wait for this handle.
710 * handles.c (_wapi_search_handle): Don't search shared handles in
713 * collection.c (collection_thread): No need to do a collection
714 scan straight away, do the waiting first.
716 2006-04-06 Dick Porter <dick@ximian.com>
718 * shared.c: Fix parameters in semctl () call.
720 2006-03-28 Zoltan Varga <vargaz@gmail.com>
722 * atomic.h atomic.c: Applied patch from David S. Miller
723 <davem@davemloft.net>: Reimplement Interlocked* primitives on sparc
724 using CAS/CASx when __GNUC__, else we will fall back to the generic
727 2006-03-27 Dick Porter <dick@ximian.com>
729 * shared.c (_wapi_shm_file_open): Break out of a loop if the
730 shared file is smaller than expected. (We loop a few times in
731 case another process is in the middle of creating the file.)
733 2006-03-22 Dick Porter <dick@ximian.com>
738 * shared.c: Delete the semaphores and shared files when the last
739 process has finished with them
741 2006-03-15 Dick Porter <dick@ximian.com>
749 * threads.c: Explicitly initialise the handle ops struct
751 2006-03-14 Dick Porter <dick@ximian.com>
756 * handles.c: Add a 'prewait' stage to the handle waiting, to give
757 waiting threads a chance to check for bogus states before
760 * mutexes.c (namedmutex_prewait): Use the prewait stage to check
761 for named mutexes that have been abandoned in a locked state (eg
762 if a process exited abnormally while owning the mutex) and
763 override it if needed.
765 2006-03-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
767 * wait.c: speed up WaitFor* when the timeout is 0.
769 2006-03-03 Dick Porter <dick@ximian.com>
771 * processes.c (ShellExecuteEx): Cope when some of the parameters
774 2006-02-27 Dick Porter <dick@ximian.com>
778 * threads.c: Comparing pthread_t with == is not portable, so use
781 Thu Feb 23 18:47:20 GMT 2006 Paolo Molaro <lupus@ximian.com>
783 * *.h, *.h: patch from Dick to make Linuxthreads systems work again.
785 2006-02-22 Dick Porter <dick@ximian.com>
788 * threads.c: There's no need to use the timed-thread support code
789 any more, as we aren't using the timed join. This greatly
790 simplifies thread setup, and fixes a memory leak (bug 77521).
792 Don't bother to store thread IDs in a hash table, use TLS instead.
793 The one case that needs to look up the handle of a different
794 thread (OpenThread()) can do the extra work itself. Fixes bug
797 * handles.c (_wapi_search_handle): Add a reference when returning
798 a private handle (shared handles are already reffed.)
800 2006-02-17 Dick Porter <dick@ximian.com>
803 * handles.c: Check handle values passed to array lookups. Fixes
806 2006-02-09 Dick Porter <dick@ximian.com>
808 * threads.c: Cope with the problems caused by attaching already
809 existing threads - they don't get the infrastructure to clean up
810 after themselves, especially the ID to handle hash. This fixes
813 2006-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
815 * shared.c: use MONO_SHARED_HOSTNAME as a substitute for gethostname()
816 when creating the shared files in the .wapi directory. Fixes bug #77371.
818 2006-02-02 Martin Baulig <martin@ximian.com>
820 * threads.c: Removed the `WITH_INCLUDED_LIBGC' section; it has
821 never been used so far.
823 * timed-thread.h (TimedThread): Removed the `stack_ptr' field; it
824 has only been used by the removed code.
826 2006-01-03 Neale Ferguson <neale@sinenomine.net>
828 * atomic.h: Correct s390x definitions and eliminate compiler warnings.
830 2006-01-03 Sebastien Pouliot <sebastien@ximian.com>
832 * io.c: Patch _wapi_stat_to_file_attributes against bug #76966, where
833 sockets could be considered as directory.
835 2005-12-23 Dick Porter <dick@ximian.com>
839 * semaphores.c: Implement OpenSemaphore
842 * mutexes.h: Implement OpenMutex
848 * event-private.h: Implement named events. Implement OpenEvent.
850 2005-12-15 Dick Porter <dick@ximian.com>
852 * processes.c (CreateProcess): The pipe-based cross-process
853 exclusion technique was trying to write NULL buffers when appname
854 was NULL (eg when coming from ShellExecuteEx,) which usually
855 succeeded even though EFAULT was returned - but sometimes it
856 failed. This meant that the child process could block forever on
857 the pipe read. Replace it with the simpler shared handle
858 semaphore protection used everywhere else. This showed up with
859 the test case in bug 76684.
861 Tue Dec 13 11:41:49 GMT 2005 Paolo Molaro <lupus@ximian.com>
863 * shared.c: fallback to private mmap when shared mmap doesn't work
866 2005-12-06 Dick Porter <dick@ximian.com>
870 * semaphore-private.h:
871 * semaphores.c: Implement named semaphores
873 2005-11-24 Dick Porter <dick@ximian.com>
875 * processes.c (GetProcessId): Implement GetProcessId()
877 2005-11-17 Dick Porter <dick@ximian.com>
880 * processes.c: Implement ShellExecuteEx as a wrapper around
883 2005-11-11 Dick Porter <dick@ximian.com>
885 * threads.c: Give mutex abandoning its own exported function, so
886 it can be called when the runtime is cleaning up.
888 * handles.c (_wapi_search_handle_namespace): Do a handle
889 collection befre starting to check namespace strings, so that any
890 stale cruft gets removed.
892 2005-11-11 Dick Porter <dick@ximian.com>
894 * threads.c: Move thread handles back into the shared space.
896 * handles.c (_wapi_handle_unref): Add support for shared handles
897 with close() handlers
899 2005-11-04 Dick Porter <dick@ximian.com>
901 * sockets.c (ioctlsocket): Use select instead of if to avoid a
902 type promotion problem on 64bit freebsd. Based on patch by Lou
903 Kamenov <kamenovl@gmail.com>, fixes bug 76447.
905 2005-11-04 Dick Porter <dick@ximian.com>
907 * io.c (file_write): Only do the file locking if
908 MONO_STRICT_IO_EMULATION is set.
910 2005-10-21 Dick Porter <dick@ximian.com>
913 * handles.c (_wapi_lookup_handle): Cope when the shared part of a
914 handle has been deleted.
915 (_wapi_handle_unref): And when the deleted shared part is pointed
916 to as a handle is deleted
918 2005-10-20 Dick Porter <dick@ximian.com>
920 * processes.c (process_set_current): If the expected process
921 handle slot doesn't contain the correct pid, create a new handle.
923 * handles.c (_wapi_search_handle): When the search doesn't find
924 anything, return failure instead of the last handle we looked at.
925 (_wapi_handle_ref, _wapi_handle_unref): Don't try to ref or unref
926 unused handles (makes tracking refcounting bugs easier.)
928 2005-10-19 Dick Porter <dick@ximian.com>
935 * collection.c (_wapi_handle_collect): Remove the shared handle
936 indirection layer, and use locking instead. Delete other
937 complexity that is no longer needed. Refcount shared handles and
938 delete them when needed, but keep the timestamps so that orphaned
939 handles will be cleaned up eventually.
941 * shared.c (_wapi_shm_file): Add processor, OS and struct size
942 info to the shared file names, to cope with dual-boot and 32/64bit
943 size issues. Fixes bug 75839.
945 * wait.c (WaitForMultipleObjectsEx): No need to distinguish
946 between shared handles and private, as the wait functions cope
947 with both together now.
949 2005-10-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
951 * io.c: removed NO_SIGPIPE macro.
952 * sockets.c: no need for MSG_NOSIGNAL or ignoring SIGPIPE.
954 2005-10-11 Dick Porter <dick@ximian.com>
956 * sockets.c (_wapi_getsockopt): Translate SO_ERROR results into
959 * error.c (errno_to_WSA): Don't return a bogus error if someone
960 asks to translate errno 0.
962 2005-10-11 Dick Porter <dick@ximian.com>
964 * handles.c: Fix several race conditions
966 2005-10-11 Miguel de Icaza <miguel@novell.com>
968 * io.c: no need to block SIGPIPE anymore, as it is ignored.
970 2005-10-05 Dick Porter <dick@ximian.com>
972 * threads.c (_wapi_thread_own_mutex, _wapi_thread_disown_mutex):
973 Keep a reference to mutexes owned by threads, so they won't be
974 destroyed prematurely. Fixes dotmsnclient crash.
976 2005-09-26 Sebastien Pouliot <sebastien@ximian.com>
978 * io.c: Apply patch from #76192 (Can't write files past 2gb on AMD64
979 (x86_64)) for Brion on IRC (Dick approved it).
981 2005-09-23 Dick Porter <dick@ximian.com>
983 * processes.c: Don't wait for processes that have already been
984 signalled; also fix typo.
986 * handles.c: Improve locking inside new handle and handle
989 2005-09-20 Dick Porter <dick@ximian.com>
992 * processes.c: Periodically waitpid for known process IDs. Fixes
995 2005-09-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
998 (CreateFile): if the file is a named pipe, treat the handle as a pipe,
999 not as a file. Fixes bug #76075.
1001 2005-08-27 Zoltan Varga <vargaz@gmail.com>
1003 * atomic.h: Add support for intel icc.
1005 2005-08-25 Zoltan Varga <vargaz@gmail.com>
1007 * io-layer.h: Include winbase.h not WinBase.h.
1009 2005-08-19 Dick Porter <dick@ximian.com>
1011 * threads.c, threads.h, thread-private.h: Use a gsize to store the
1012 thread ID, so it can hold a 64 bit value if needed.
1014 2005-07-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1016 * error.c: map ENOENT to WSAECONNREFUSED. It might happen when
1017 connecting to unix sockets. Closes bug #75632.
1019 2005-07-05 Dick Porter <dick@ximian.com>
1021 * io.c: Make sure SIGPIPE is ignored when calling write(2).
1022 Prevents the runtime exiting when writing to a closed pipe,
1025 2005-06-30 Dick Porter <dick@ximian.com>
1027 * shared.c (_wapi_shm_semaphores_init): Add some helpful error
1028 messages when semget () fails due to lack of resources.
1030 2005-06-21 Dick Porter <dick@ximian.com>
1035 * threads.c: Keep a list of owned mutexes in each thread handle,
1036 so that it is easier to abandon them when the thread exits.
1037 Removes a bottleneck when multiple threads are finishing in
1040 2005-06-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1042 * io.c: (GetLogicalDrives) when a bogus line is read, don't leak memory.
1043 When the buffer has not enough space, close the file before returning.
1045 2005-06-09 Duncan Mak <duncan@novell.com>
1047 * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to
1048 all public headers. Fixes #74919.
1050 2005-05-30 Zoltan Varga <vargaz@freemail.hu>
1052 * atomic.h: Add IA64 atomic ops.
1054 2005-05-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1056 * processes.c: make ExitCode be valid even if the user didn't call
1057 WaitForExit() and is just polling on HasExited.
1059 2005-05-17 Dick Porter <dick@ximian.com>
1061 * io.c (file_getfilesize): Clear the error value, so that files
1062 with sizes with the low bits 0xFFFFFFFF can be distinguished from
1065 2005-05-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1067 * shared.c: forgot to ignore a warning.
1069 2005-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1071 * shared.c: don't display warnings after reboots.
1073 2005-05-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1075 * sockets.c: on windows, getsockopt/setsockopt for send/receive timeout
1076 use an integer in milliseconds. We were using a struct timeval.
1078 2005-05-06 Dick Porter <dick@ximian.com>
1080 * handles-private.h:
1087 * collection.h: Use SysV semaphores for managing access to the
1088 shared memory - in return for the ludicrous api we get
1089 synchronisation primitives that can be cleaned up by the kernel
1090 even when a process quits unexpectedly. This removes the
1093 2005-05-05 Lluis Sanchez Gual <lluis@novell.com>
1095 * handles.c: Always use polling in the waits, since
1096 mono_cond_timedwait can't be interruped by the thread abort signal.
1098 2005-04-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1100 * events.c: calling Set on AutoResetEvent several times has the same
1101 effect as calling it only once if no thread is waiting for it.
1103 2005-04-29 Dick Porter <dick@ximian.com>
1105 * processes.c (EnumProcesses): Use a GArray instead of a GPtrArray
1106 now it's storing pids not handles, also fixes memory leak caused
1107 by unclear glib documentation.
1109 * sockets.c (WSACleanup): Remove unused variable
1111 2005-04-29 Dick Porter <dick@ximian.com>
1113 * handles.c (_wapi_handle_check_share_by_pid): For systems that
1114 don't have file descriptor info in /proc check that the original
1115 opener of a file is still there, if a share violation would
1118 2005-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1121 * handles-private.h: added _wapi_handle_forecch that loops through all
1122 the handles and call a callback function when a handle of the given
1125 * sockets.c: no need to keep open sockets in an array, as we have them
1126 in the handles structure.
1130 2005-04-28 Dick Porter <dick@ximian.com>
1132 * processes.c: Cope with handles that are only around for as long
1133 as the search is running. If we're searching for process handles,
1134 check to see if the process is still running and signal it if not.
1136 * handles.c (_wapi_search_handle): Search in the shared space as
1137 well. Fixed bug 74752.
1140 * handles.c (_wapi_handle_new_from_offset):
1141 _wapi_handle_new_for_existing_ns () was doing exactly the same as
1142 this, so deleted it.
1144 2005-04-26 Dick Porter <dick@ximian.com>
1146 * handles.c: Fix stupid thinko where if a new shared handle is
1147 created but a collection was needed to free some space, it
1148 returned an error anyway. Should fix the messages shown in bug
1151 2005-04-25 Dick Porter <dick@ximian.com>
1153 * handles.c (_wapi_handle_check_share): Only consider mono
1154 processes when looking to see if a file is still being held open,
1155 while checking share permissions.
1157 2005-04-25 Dick Porter <dick@ximian.com>
1161 * wapi-private.h (struct _WapiHandleOps):
1162 * handles.c (_wapi_handle_unref): When destroying handles, save
1163 the handle data and call the close function only after the array
1164 slot has been cleared. This prevents race conditions with file
1165 descriptors, fixing bug 74713.
1167 * mutexes.c: Delete the handle close functions, they didn't do
1170 * error.c (_wapi_get_win32_file_error): Add a mapping for EINTR so
1171 the "Unknown error" g_warning doesn't get displayed.
1173 2005-04-25 Dick Porter <dick@ximian.com>
1176 * threads.c: Make thread handles process-private for now to take
1177 some of the space pressure off the shared memory, while I work on
1180 2005-04-21 Dick Porter <dick@ximian.com>
1182 * handles.c (_wapi_handle_check_share): Make sure there is a "fd"
1183 dir in /proc before blowing away handle info. Fixes bug 74649.
1185 2005-04-21 Dick Porter <dick@ximian.com>
1187 * wait.c (WaitForMultipleObjectsEx): Implement special waits
1189 * handles.c (_wapi_handle_wait_signal_poll_share): Don't return a
1190 timeout, just wait briefly for the private signals and let the
1191 waiting thread test again. This prevents us missing shared
1194 2005-04-21 Dick Porter <dick@ximian.com>
1196 * collection.h (_WAPI_HANDLE_COLLECTION_EXPIRED_INTERVAL): Reduce
1197 the time before a slot is considered too old and deleted. This is
1198 a workaround while I come up with a proper fix.
1200 2005-04-21 Dick Porter <dick@ximian.com>
1205 * handles.c (_wapi_handle_new): Turn assertions into errors.
1207 * collection.c (_wapi_handle_collect): Use symbols not magic
1208 numbers for timeout values
1210 2005-04-19 Dick Porter <dick@ximian.com>
1214 * handles.c (_wapi_handle_count_signalled_handles)
1215 * handles-private.h (_wapi_handle_shared_lock_handle): Use new
1216 shared handle locks in critical sections.
1218 * handles.c (_wapi_handle_new_for_existing_ns): Reuse old handles
1219 if there is already one there.
1221 * handles.c (_wapi_handle_ref): It was possible for a process to
1222 exit before getting around to updating shared handle timestamps,
1225 Tue Apr 19 16:25:47 CEST 2005 Paolo Molaro <lupus@ximian.com>
1227 * threads.c: fix lookup of the thread id in the has table:
1228 always use the id value, not the pointer to the id.
1230 2005-04-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1232 * handles.c: fix handle returned in _wapi_handle_search_handle. Dick
1235 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1237 * io-layer/sockets.c: FIONBIO with a TRUE argument means we want
1238 non-blocking IO, not the other way around.
1240 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1244 * handles-private.h: GetFileType wasn't checking if we have memory
1245 allocated for the handle before dereferencing it. Fixes a FileStream
1248 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1252 * handles-private.h: we were calling g_renew to expand the handle array,
1253 but that might move the memory and we might have pthread conditions or
1254 mutexes in the original memory area that are being used. Now instead of
1255 expanding an existing array, we just create new ones and keep a list of
1256 them. Access to _wapi_private_handles had to be modified accordingly.
1258 2005-04-15 Dick Porter <dick@ximian.com>
1260 * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN
1262 2005-04-14 Raja R Harinath <rharinath@novell.com>
1264 * wapi-private.h: Remove reference to 'daemon-private.h'.
1266 Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro <lupus@ximian.com>
1268 * atomic.h: applied patch from mass@akuma.org (David Waite)
1269 to fix InterlockedExchangeAdd.
1270 Fixed a few other functions, including InterlockedCompareExchange()
1271 which was miscompiled by gcc with optimizations enabled.
1273 2005-04-13 Dick Porter <dick@ximian.com>
1275 * io.c (share_check):
1276 * handles.c (_wapi_handle_check_share): Refine the file check so
1277 that sharing violations within the same process don't cause
1280 2005-04-13 Dick Porter <dick@ximian.com>
1282 * io.c (FindFirstFile): Fix bugs introduced with the merge (bug
1285 2005-04-12 Dick Porter <dick@ximian.com>
1287 The daemon-less io-layer. Extensive lowlevel changes in
1288 handles.c, requiring some corresponding changes in other files
1289 calling these functions. Private_foo structures have been
1292 File descriptor handling differences account for most of the
1293 changes in io.c and sockets.c.
1297 * mutexes.c: Named mutexes are now a distinct type.
1298 * atomic.h: Fix a PPC uninitialised variable warning.
1299 * wait.c: Check conditions before waiting on a condition variable.
1300 * processes.c: Handle process fork and wait without a daemon
1301 (though this has the limitation of only being able to wait for
1304 2005-04-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1311 * sockets.h: removed dead code that deals with async IO.
1313 2005-03-30 Zoltan Varga <vargaz@freemail.hu>
1315 * atomic.c (InterlockedIncrement): Fix fallback implementation of
1316 InterlockedIncrement and InterlockedDecrement. Fixes #74228.
1318 2005-03-29 Sebastien Pouliot <sebastien@ximian.com>
1320 * io-layer.h: Add required header files for compiling with VS.NET.
1322 2005-03-17 Miguel de Icaza <miguel@novell.com>
1324 * io.c: don't fail on NFS when there are no more locks available.
1326 2005-03-09 Dick Porter <dick@ximian.com>
1328 * error.c (_wapi_get_win32_file_error): ENFILE and EMFILE should
1329 map to ERROR_TOO_MANY_OPEN_FILES, not ERROR_NO_MORE_FILES. Fixes
1332 2005-03-09 Dick Porter <dick@ximian.com>
1334 * daemon.c (process_process_fork): Initialise the handle data
1335 before using it in the error case. This is probably the error
1336 we're working around in the previous change. Spotted by Taru Jain
1337 <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.
1339 2005-03-07 Dick Porter <dick@ximian.com>
1341 * daemon.c: It looks like g_shell_parse_argv() can return
1342 argv[0]=NULL somehow, yet still not give an error. Make sure we
1343 don't pass NULL to strrchr(), working around a segfault that
1344 showed up on ZLM testing.
1346 2005-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1348 * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is
1349 the expected error code showed by the test case in bug #73053.
1351 2005-02-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1353 * io.c: another leftover.
1355 Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1357 * io.c: fixed logic in checking errno in rev 40815.
1359 Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1361 * threads.c: we don't depend on the GC checking tls
1363 * processes.c: remove unused ref to GC headers.
1365 Thu Feb 17 19:57:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1367 * io.c: remove _wapi_thread_cur_apc_pending () checks
1368 when the siscall should return immediatly and handle
1369 the case when a syscall is interrupted without
1370 erroring out, but returning a 0 read/write if possible.
1371 Still the cases of read from file need to be handled.
1373 Tue Feb 8 18:28:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1375 * threads.c: make people test with 1 MB stack per thread.
1377 2005-01-17 Dick Porter <dick@ximian.com>
1379 * timefuncs.h: Make WapiFileTime endian-aware, as it's often
1380 cast to and from 64bit ints. Fixes bug 71213.
1382 2005-01-11 Dick Porter <dick@ximian.com>
1384 * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
1387 Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>
1389 * atomic.h: Fix functions on s390.
1391 Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>
1393 * atomic.h: fix some functions on ppc (tests/interlocked.cs).
1395 2005-01-10 Dick Porter <dick@ximian.com>
1397 * misc.c (_wapi_calc_timeout): Guard against overflow when
1398 calculating timeouts. This makes waiting with a large
1399 (Int32.MaxValue) timeout not return immediately.
1401 2004-12-23 Ben Maurer <bmaurer@ximian.com>
1403 * io.c (io_ops): make this `const' so it is shareable (well, only
1404 really shareable if it is statically linked...)
1406 Mon Dec 20 11:58:33 CET 2004 Paolo Molaro <lupus@ximian.com>
1408 * threads.c, threads.h: add accessor to get the pthread_key_t for
1411 2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1413 * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS
1414 if it exists and is not the same as 'src'.
1416 2004-12-01 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1418 * atomic.h : Fix InterlockedCompareExchange for s390/s390x.
1420 2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1422 * processes.c: unquote the cmd path, allow for ' or " when quoting and
1423 pass the quoted program name to the daemon, otherwise the call to
1424 g_shell_unquote in the daemon will break things up.
1426 2004-10-14 Dick Porter <dick@ximian.com>
1428 * sockets.c (_wapi_accept): Revert the previous change. We now
1429 set the accepted socket to have the same blocking status as the
1430 listening socket in managed code. This follows MS behaviour.
1432 2004-10-14 Dick Porter <dick@ximian.com>
1434 * sockets.c (_wapi_accept): On Darwin, make sure a newly
1435 accept()ed socket is blocking. Fixes bug 67355, patch by
1436 grompf@sublimeintervention.com.
1438 2004-10-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1440 * system.c: check the number of online processors instead of the
1441 existing ones. Sanitize return value if it's an error.
1443 2004-10-03 Ben Maurer <bmaurer@ximian.com>
1445 * system.c: Add support for getting the # of cpus.
1447 2004-09-28 Dick Porter <dick@ximian.com>
1449 * io.c (pipe_close_private): Fix one small typo in the last change
1450 that totally hosed process creation with redirected pipes.
1452 2004-09-24 Dick Porter <dick@ximian.com>
1459 * handles-private.h: Cope when a file descriptor is reused while
1460 the handle that thought it owned it is still referenced, instead
1461 of asserting. Probably fixes bug 66479, though we've been unable
1464 2004-09-09 Dick Porter <dick@ximian.com>
1467 * io.c: Set error codes everywhere.
1469 2004-09-06 Dick Porter <dick@ximian.com>
1471 * handles.c (_wapi_handle_unref): Reset the private record's type
1472 (CloseHandle): Check for a fd mapping failure, and return FALSE.
1473 (_wapi_handle_process_fork): Fix long-standing bug in checking
1474 handle return values. Also do the required bookkeeping with the
1475 new process's handles.
1477 * daemon.c: When creating a new process's handles, check whether
1478 the shared space needs to be increased
1480 2004-09-05 Zoltan Varga <vargaz@freemail.hu>
1482 * shared.c (_wapi_shm_file): Fix leaking of filename.
1484 2004-08-19 Dick Porter <dick@ximian.com>
1486 * handles.c (_wapi_handle_count_signalled_handles): Fix thinko
1487 introduced with the fd offset stuff: unlock handles properly when
1488 backing off. Fixes the monologue hang at exit.
1490 2004-08-18 Dick Porter <dick@ximian.com>
1493 * io.c: Check that new fds fit in the table, return error if not
1495 * daemon.c (_wapi_daemon_main):
1496 * handles.c (shared_init): Have all processes agree on a size for
1499 2004-08-17 Dick Porter <dick@ximian.com>
1501 * daemon.c (process_new):
1502 * handles.c (_wapi_handle_new_internal): Cope when the space
1503 reserved for file descriptors is larger than the shared segment
1504 size. Fixes the crash reported when running mono under gdb on
1507 2004-08-16 Dick Porter <dick@ximian.com>
1511 * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
1512 error checking with passed-in file descriptors.
1514 2004-08-11 Dick Porter <dick@ximian.com>
1517 * io.c: Returned handle values are the file descriptor the handle
1521 * handles-private.h:
1522 * daemon.c: Reserve the range of handles that can have the same
1523 values as file descriptors. These won't be used, but the values
1524 will be used as file, console, pipe or socket handles. The fd to
1525 handle mapping is done internally and is invisible to users.
1528 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
1529 reserve a chunk of handle space.
1531 2004-08-04 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1533 * atomic.h: add support for 64-bit S/390
1535 2004-07-22 Dick Porter <dick@ximian.com>
1538 * threads.c: Move the destruction of the internal thread data to
1539 after the thread has been joined. Fixes bug 61418.
1541 2004-07-14 Dick Porter <dick@ximian.com>
1543 * wait.c (test_and_own): When not waiting for all handles to
1544 become signalled, only own and return the lowest. All the
1545 documentation suggests that the old way was correct, but
1546 experimentation shows it actually works like this. Patch by
1547 Sébastien Robitaille
1548 (sebastien.robitaille@croesus.com), fixes bug 61511.
1550 2004-07-09 Ben Maurer <bmaurer@ximian.com>
1552 * threads.c: register roots for gc
1554 2004-07-08 Dick Porter <dick@ximian.com>
1556 * io.c (file_seek): If there is a high 32bit offset part, make
1557 sure the low part isn't sign-extended. Set error codes when
1558 returning failure. Fixes bug 61131.
1560 2004-07-06 Dick Porter <dick@ximian.com>
1562 * io.c (file_setfiletime): Check for underflow when converting to
1563 time_t values. Set error codes when returning failure. Fixes bug
1566 2004-07-05 Dick Porter <dick@ximian.com>
1568 * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable.
1570 * daemon.c (unref_handle): Only destroy a handle if all processes
1571 have released it, not just the current one. Fixes bug 60887.
1573 2004-06-30 Zoltan Varga <vargaz@freemail.hu>
1575 * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
1576 to prevent warnings.
1578 2004-06-24 Dick Porter <dick@ximian.com>
1580 * mutexes.c: Indicate when a named mutex was reused
1582 2004-06-24 Dick Porter <dick@ximian.com>
1584 * threads.c (SuspendThread):
1585 * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a
1586 while loop. See bug 58161.
1588 Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro <lupus@ximian.com>
1590 * io.c: don't use sharemode for on-disk file permissions: it's used
1591 for shared access to the open file.
1593 2004-06-22 Dick Porter <dick@ximian.com>
1595 * events.c (CreateEvent): When creating an auto-reset event that
1596 is initially owned, make sure the set count starts at 1.
1598 2004-06-18 Dick Porter <dick@ximian.com>
1601 * events.c: Auto-reset events need to release one thread for each
1602 time SetEvent() is called. Fixes bug 41292.
1606 * mutexes.c: Scan for mutexes that are still locked by a thread
1607 when it exits. Fixes the MS demo app linked by bug 41292.
1609 * wait.c (test_and_own): Make sure a handle is signalled before it
1612 2004-06-16 Dick Porter <dick@ximian.com>
1614 * timed-thread.c: Call the thread cleanup exit routine before taking
1615 the join mutex, because this could deadlock if another thread tries
1616 to join in the meantime. This fixes the hang-at-exit problem seen
1619 2004-06-03 Lluis Sanchez Gual <lluis@ximian.com>
1621 * threads.c: Implemented SleepEx.
1622 * threads.h: Fixed SleepEx signature.
1624 2004-06-03 Miguel de Icaza <miguel@ximian.com>
1626 * threads.c: When running under valgrind, do not allocate too much
1627 stack, as Valgrind default is 1 meg.
1629 2004-05-27 Dick Porter <dick@ximian.com>
1632 * io.c: Implemented LockFile() and UnlockFile()
1634 2004-05-21 Dick Porter <dick@ximian.com>
1636 * io.c (CreateFile): Check for existing share modes when opening
1640 * handles-private.h:
1641 * daemon-messages.h:
1642 * daemon.c: Maintain a hash of file share modes, keying on device
1643 and inode (to cope with symlinks.)
1645 2004-05-20 Lluis Sanchez Gual <lluis@ximian.com>
1647 * daemon-messages.c: Retry if the communication with the daemon is
1648 interrupted by a signal.
1649 * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped.
1650 Only return an error in this case if there is something in the apc queue
1651 (which means that it is an interruption requested by the "user").
1652 * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as
1653 true since the wait is small.
1654 * shared.c: Retry write calls when interrumped by a signal.
1655 * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which
1656 returns TRUE if there are pending asynchronous calls (APC) for the
1657 provided thread. Also added _wapi_thread_dispatch_apc_queue which calls
1658 the enqueued APCs. Defined a new struct ApcInfo that holds information
1659 about an enqueued APC.
1660 * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same
1661 as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue.
1662 These last two methods call the corresponding apc methods in
1663 thread-private using the provided thread handle.
1664 * threads.h: Added QueueUserAPC.
1665 * uglify.h: Added WapiApcProc (needed by QueueUserAPC).
1666 * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and
1667 WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support
1668 for APCs in those two methods and also in SleepEx.
1670 2004-05-17 Dick Porter <dick@ximian.com>
1672 * io.c (CopyFile): Speed up. Fixes bug 57859.
1674 2004-05-13 Dick Porter <dick@ximian.com>
1675 * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current
1676 thread doesn't own the mutex, rather than assert()ing.
1678 2004-05-11 Dick Porter <dick@ximian.com>
1680 * shared.c (_wapi_shm_attach): Cope when a previous daemon startup
1681 attempt failed, leaving shared files that look like a daemon is
1684 2004-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1687 (SetFileAttributes): don't the the exec bit if the corresponding read
1690 2004-05-10 Zoltan Varga <vargaz@freemail.hu>
1692 * io.c (FindFirstFile): Fix invalid free.
1694 2004-05-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1696 * io.c: translate from GFileError to errno codes and don't free
1697 variables right after calling mono_io_scandir, as we may overwrite
1700 2004-05-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1702 * io.c: g_dir_open return ENOENT for directories on which we don't have
1703 read/execute permission, while returning EPERM for anything below those.
1704 So, change ENOENT by EPERM if the directory exists.
1706 2004-05-07 Dick Porter <dick@ximian.com>
1708 * io.c (SetFileAttributes): Don't have failed chmod()s cause a
1709 "file not found" error. Fixes bug 54032.
1711 2004-05-07 Dick Porter <dick@ximian.com>
1713 * io.c (FindFirstFile): Comment out a windows-compatibility check
1714 that breaks when directories have metachars in their names.
1715 Workaround for bug 58116.
1717 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1719 * io.c: fixed for FindFirstFile for empty directories. Closes
1722 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1724 * processes.c: set the start time for the current process. Fixes bug
1727 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1729 * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
1730 * io.c: implemented scandir using glib functions.
1732 2004-05-04 Dick Porter <dick@ximian.com>
1734 * daemon.c (read_message): Return FALSE on error so the GSource
1735 callback itself can return FALSE. Cures the infinite loop poll()
1737 * shared.c: Fix some daemon startup race conditions.
1739 2004-04-29 Miguel de Icaza <miguel@ximian.com>
1741 * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k,
1742 use the stack, do not use dynamic memory.
1744 2004-04-29 Zoltan Varga <vargaz@freemail.hu>
1746 * io.c: Add scandir implementation for platforms which do not have
1749 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1751 * io.[ch]: implemented GetLogicalDriveStrings.
1753 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1756 * sockets.c: use the field name from configure when accessing sigval
1757 pointer field. Makes this work on the Mac.
1759 2004-04-28 Bernie Solomon <bernard@ugsolutions.com>
1761 * atomic.c: (InterlockedExchange) fix typo for
1764 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1767 * sockets.c: added check for sys/aio.h.
1769 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1771 * error.[ch]: added _wapi_get_win32_file_error...
1772 * io.c: ... which was _wapi_get_win32_error here.
1773 * sockets.c: rename the function calls here too.
1775 2004-04-28 Dick Porter <dick@ximian.com>
1777 * daemon-messages.c: Avoid a deadlock when a thread is killed while
1778 waiting for the daemon by using a recursive mutex. Helps bug 56699.
1780 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1782 * io.c: fixed leak in async_notifier().
1784 * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl
1787 * threads.c: removed old comment.
1789 2004-04-26 David Waite <mass@akuma.org>
1791 * daemon-messages.h:
1798 * wapi-private.h: remove comma from end of enumeration declarations
1799 * status.h: cast unsigned int types to int for enum assignment
1801 2004-04-26 David Waite <mass@akuma.org>
1804 * timefuncs.c: declare 64-bit constants as long long types (i.e.
1807 2004-04-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1809 * socket-wrappers.h: _wapi_socket == WSASocket now. Added
1810 WSA_FLAG_OVERLAPPED.
1812 * sockets.c: new unused parameters for _wapi_socket.
1814 2004-04-22 Miguel de Icaza <miguel@ximian.com>
1816 * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle
1817 the fact that MacOS X is a piece of junk (sem_init is *defined* in
1818 the libc, but they return `not implemented').
1820 2004-04-22 Dick Porter <dick@ximian.com>
1823 * handles-private.h: Reference the handle when it is locked, so
1824 that another thread can't blow it away while we're waiting for it
1825 to become signalled.
1836 * handles-private.h:
1839 * daemon-messages.c:
1840 * critical-sections.c:
1841 * atomic.c: Added pthreads cleanup handlers and error asserts
1844 * handles.c: Fixed the gcc "variable might be used uninitialised"
1845 warnings. They can't happen, but gcc doesn't know that
1846 g_assert()s don't return.
1848 Fixed the declaration of _wapi_handle_process_kill() so that it
1849 expects the correct type for the pid.
1851 * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that
1852 hasn't been used in ages and just made the code more complex.
1854 2004-04-17 Zoltan Varga <vargaz@freemail.hu>
1856 * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
1857 warnings. Fixes #57168.
1859 2004-04-16 Dick Porter <dick@ximian.com>
1861 * threads.c (Sleep): Using div(3) with a negative (when signed)
1862 numerator causes the quotient to be 0 and the remainder to be the
1863 numerator. This feeds a small negative value to nanosleep(3),
1864 which will return immediately and cause a busy wait. Fixes bug
1867 2004-04-15 Dick Porter <dick@ximian.com>
1870 * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3)
1871 and fnmatch(3) instead of glob(3). glob() can't cope with being
1872 given filenames containing metachars. This fixes bug 40557.
1874 2004-04-14 Bernie Solomon <bernard@ugsolutions.com>
1876 * security.c: #warning is a GCC-ism
1878 2004-04-13 Sebastien Pouliot <sebastien@ximian.com>
1880 * security.c: Removed GetUserName as glib g_get_user_name does a
1881 better (portability) job. Added ImpersonateLoggedOnUser and
1884 2004-04-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1886 * mono-mutex.h: move pthread_mutex_timedlock declaration to...
1887 * mono-mutex.c: ...here. It was causing a warning that prevented
1888 libgdiplus compilation.
1890 2004-04-04 Miguel de Icaza <miguel@ximian.com>
1892 * security.c (GetUserName): Make it work on MacOS X
1894 2004-04-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1896 * security.c: use getpwuid_r if available. This one is thread-safe.
1898 2004-04-02 Sebastien Pouliot <sebastien@ximian.com>
1900 * Makefile.am: Added security.c|h.
1901 * security.c: New file for security related functions. Added function
1902 GetUserName to fix #56144.
1903 * security.h: New. Header file for security.c
1904 * wapi.h: Added include for security.h
1906 2004-03-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1908 * daemon-messages.h: added kill structs.
1910 * daemon.c: implemented process_process_kill.
1911 * handles-private.h: define process_process_kill.
1912 * handles.c: implemented _wapi_handle_process_kill.
1913 * processes.[ch]: implemented TerminateProcess.
1915 2004-03-25 Bernie Solomon <bernard@ugsolutions.com>
1917 * daemon.c (rem_fd): On solaris you seem to get an
1918 error even after removing the input source so don't
1919 try and rem_fd it twice.
1921 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
1923 * daemon.c: in process_post_mortem, If the child terminated due to the
1924 receipt of a signal, the exit status must be based on WTERMSIG, since
1925 WEXITSTATUS returns 0 in this case.
1927 2004-03-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1929 * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.
1931 2004-03-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1933 * daemon.c: only call getdtablesize () once.
1934 * processes.c: wait 500 ms to check if execve failed and throw the same
1935 exception as MS on failure. Fixes bug #32809.
1937 2004-03-17 Bernie Solomon <bernard@ugsolutions.com>
1939 * io.c (async_notifier): use "union sigval" rather
1940 than sigval_t as Solaris doesn't have sigval_t
1941 (which isn't in IEEE 1003.1 either).
1943 2004-03-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1945 * io.c: added debug stuff and removed a few redundant lines in
1948 2004-03-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1950 * io-private.h: added new fields for file structure. Declare
1951 _wapi_io_add_callback.
1953 * io.c: added _wapi_get_win32_error, support aio_read/write in
1954 file_read/write. Implemented _wapi_io_add_callback, which is where
1957 * io.h: added new fields for WapiOverlapped and typedef for the
1960 * processes.c: fixed off-by-one bug when handling environment variables
1963 * threads.[ch]: implemented BindIoCompletionCallback.
1965 * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE.
1967 2004-03-14 Zoltan Varga <vargaz@freemail.hu>
1969 * socket-wrappers.h: Remove extra semicolon.
1971 2004-03-03 Dave Camp <dave@ximian.com>
1973 * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
1974 Use a new main context.
1976 2004-03-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1979 (GetFileAttributes): set the error depending on errno instead of
1980 setting ERROR_FILE_NOT_FOUND always. See bug #55160.
1982 2004-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1985 (CopyFile): free the buffer on error.
1987 (WSAIoctl): free the buffer on error.
1989 2004-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1991 * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT.
1993 * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW
1994 using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style.
1996 2004-01-27 Bernie Solomon <bernard@ugsolutions.com>
1998 * shared.c (_wapi_shm_file): add hostname
1999 to shared data file names to handle NFS mounted
2002 Mon Jan 26 16:15:03 CET 2004 Paolo Molaro <lupus@ximian.com>
2004 * sockets.h: remove obsolete soklen_t typedef.
2006 Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>
2008 * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket
2009 wrappers to its own non-installed header file.
2011 2004-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2014 (FindFirstFile): unlock the handle if FindNextFile fails.
2015 (FindNextFile): g_free a couple of pointers before retrying.
2018 (WaitForMultipleObjects): if only one handle provided, use
2019 WaitForSingleObject.
2021 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2023 * handles-private.h: (_wapi_handle_type) check
2024 for segment in range before using it
2026 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2028 * thread-private.h: _wapi_thread_ops is now const
2031 Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>
2033 * threads.c, timed-thread.c, timed-thread.h: use mach
2034 semaphores on Darwin (MacOSX) since the posix ones
2035 are mostly broken there (threads are not created suspended
2036 and they can start executing before they are fully initialized
2037 like in tests/thread-static.cs).
2039 Mon Dec 22 17:18:45 CET 2003 Paolo Molaro <lupus@ximian.com>
2041 * atomic.h: ppc fixes.
2043 2003-12-19 Bernie Solomon <bernard@ugsolutions.com>
2045 * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
2048 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2050 * shared.c: (_wapi_shm_open) make scratch file
2051 not have to immediately regrow to avoid remaps
2052 (HPUX can't cope with these).
2053 (_wapi_shm_attach) use actual size of file
2054 to set scratch data_len for the creating process.
2056 * handles.c: (_wapi_handle_new_internal) make
2057 sure mutex & cond var are initialized even for
2058 non process shared ones.
2059 (_wapi_handle_unref) always call destroy
2060 routines on mutex & cond var
2062 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2064 * daemon.c: change channel data structure so
2065 input sources are removed from glib event loop
2066 properly. xsp works better on Solaris and
2069 2003-12-12 Bernie Solomon <bernard@ugsolutions.com>
2071 * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
2072 definition with file & line number for non-GCC
2075 2003-12-08 Bernie Solomon <bernard@ugsolutions.com>
2077 * Makefile.am: make sure hppa_atomic.s is in distribution
2079 2003-12-01 Dick Porter <dick@ximian.com>
2082 * mutexes.c (CreateMutex):
2083 * mutex-private.h (struct _WapiHandle_mutex):
2084 * handles.c: Look up certain handle types by name, in a shared
2085 namespace. Currently only mutex handles have this implemented.
2088 * semaphores.c (CreateSemaphore):
2089 * events.c (CreateEvent): Fix signature
2091 2003-11-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2093 * io.c: don't call g_free before testing errno as it may modify it.
2094 If the path exists, return an error if it's not a directory. Fixes
2097 2003-11-20 Dick Porter <dick@ximian.com>
2099 * io.c: Missed a little-endian UTF16 conversion. Patch from
2100 Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.
2102 2003-10-29 Dick Porter <dick@ximian.com>
2104 * io.c (MoveFile): If the move crosses filesystems, try and fall
2105 back to copy and delete. Patch from Jörg Rosenkranz
2106 (JoergR@voelcker.com), fixes bug 50298.
2108 2003-10-28 Dick Porter <dick@ximian.com>
2110 * io.c: Use the new encoding conversion to cope with non-utf8
2111 locales in filenames.
2113 * processes.c: Ditto for process arguments.
2115 Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro <lupus@ximian.com>
2117 * atomic.h: some ppc inline asm fixes (incorrect use of labels,
2118 incorrect register constraints, incorrect clobber lists).
2120 2003-10-13 Bernie Solomon <bernard@ugsolutions.com>
2122 * Makefile.am hppa_atomic.s: add HP 64bit
2123 implementation of atomic ops
2125 2003-10-13 Zoltan Varga <vargaz@freemail.hu>
2127 * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
2128 a conditional for platforms that don't have it.
2130 2003-10-09 Bernie Solomon <bernard@ugsolutions.com>
2132 * threads.c: (CreateThread) use stacksize argument
2133 if non-zero - change default for 64 bits to 4Mb
2135 2003-09-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2137 * sockets.c: set last error when socket creation fails. This shed some
2138 light on bug #49015.
2140 2003-09-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2142 * processes.c: fixed bug #48973: we only change \ by / for the argument
2143 to be used as command.
2144 When getting the program name from the args, don't let the space between
2147 2003-09-24 Bernie Solomon <bernard@ugsolutions.com>
2149 * atomic.h atomic.c: fix sparc so lock is
2150 global, increment does so and it compiles under Sun compiler.
2152 2003-09-22 Bernie Solomon <bernard@ugsolutions.com>
2154 * handles.c: include <string.h> directly as may
2155 not be nested in <sys/un.h> like Linux
2157 2003-09-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2160 (DeleteFile): call SetLastError on failure. Fix by
2161 richard.torkar@htu.se (Richard Torkar). Closes bug #48222.
2163 2003-09-15 Lluis Sanchez Gual <lluis@ximian.com>
2165 * daemon.c: In compare_process(), discard handles already signalled.
2167 2003-09-02 Dick Porter <dick@ximian.com>
2169 * io.c: Work around glib brain-dead assumptions about utf8-encoded
2170 filenames. Fixes bug 30781.
2172 2003-08-28 Dick Porter <dick@ximian.com>
2174 * critical-sections.c: Patch from Bernie Solomon
2175 <bernard@ugsolutions.com> to emit a warning if locking a critical
2178 2003-07-23 Dick Porter <dick@ximian.com>
2181 * daemon.c (maybe_exit): Avoid the race condition when the daemon is
2182 closing but another client comes along when the shared data is still
2183 visible. Should fix bugs 33671 and 35213.
2185 2003-07-23 Dick Porter <dick@ximian.com>
2187 * handles.c: Initialise handle mutex and cond. Fix by
2188 Bernie Solomon <bernard@ugsolutions.com>
2190 2003-07-15 Dick Porter <dick@ximian.com>
2192 * timed-thread.c (timed_thread_start_routine): Fix virtual memory
2193 leak when threads quit. Fixes bug 44067.
2195 Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro <lupus@ximian.com>
2197 * io.c: never add write permission for group or others in
2198 SetFileAttributes ().
2200 2003-06-17 Dick Porter <dick@ximian.com>
2202 * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
2203 ignore the unsupported ones ("fixes" bug 44977).
2205 2003-06-17 Lluis Sanchez Gual <lluis@ximian.com>
2207 * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for
2208 high ms values (there was an overflow).
2210 2003-06-17 Zoltan Varga <vargaz@freemail.hu>
2212 * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.
2214 2003-06-11 Dick Porter <dick@ximian.com>
2216 * shared.c: Fix shared directory creation. Patch from
2217 Pablo Baena <pbaena@uol.com.ar>
2219 2003-06-10 Dick Porter <dick@ximian.com>
2221 * atomic.c: Delete the useless compile warning
2223 2003-06-09 Dick Porter <dick@ximian.com>
2225 * daemon.c: Lookup env as a string array. Fixes bug 44289. Also
2226 make setting the process handle value in the environment actually
2229 * processes.c: Pretty up the process name, if it happens to be
2230 "mono" such as when another mono process forks "mono foo.exe"
2232 2003-06-05 Dick Porter <dick@ximian.com>
2234 * processes.c (process_set_current): Don't do an expensive handle
2235 search at application startup, check the environment to see if the
2236 process handle has already been created.
2238 * io.c: Don't do an expensive handle search when creating stdin,
2239 stdout and stderr handles, just create them all the first time one
2246 * handles-private.h:
2247 * daemon-messages.h:
2249 * daemon.c: Support for "unlimited" number of handles and scratch
2252 Speed up application startup by passing process handle in the
2253 environment, rather than let the app scan all handles (which gets
2254 really slow when there are more than a few thousand to check.)
2256 Initialise some structs passed to syscalls, noticed by valgrind.
2259 2003-05-20 Dick Porter <dick@ximian.com>
2261 * io.c (FindFirstFile): Include . files in the glob. Fixes bug
2264 2003-05-19 Dick Porter <dick@ximian.com>
2266 * threads.c: Set the new thread's stack size to 2M. Fix needed
2267 for BSD, reported by Martin Dvorak <md@9ll.cz>
2269 2003-05-16 Dick Porter <dick@ximian.com>
2272 * io.c: Implement GetTempPath()
2274 2003-05-16 Dick Porter <dick@ximian.com>
2276 * processes.c (CreateProcess): Set some error codes
2278 2003-05-12 Dick Porter <dick@ximian.com>
2280 * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
2281 Patch from Martin Dvorak <mdvorak@ninell.cz>.
2283 2003-05-10 Dick Porter <dick@ximian.com>
2285 * io.c (CopyFile): Copy file mode as well as file data. Based on
2286 suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
2289 2003-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2291 * handles.c: don't call GC_gcollect when creating new handles.
2293 2003-05-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2295 * handles.c: added some debugging code. Call GC_gcollect
2296 before creating a new handle. It makes Lupus' test run smoother and
2297 faster (from 62 to 83 request per second). Notice that calling
2298 GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does
2299 not improve nor degrade the performance, so i don't do it.
2301 2003-05-02 Dick Porter <dick@ximian.com>
2303 * sockets.c: Rearrange closesocket() and socket_close_private(),
2304 and remember to unref the handle, so we don't leak socket handles.
2305 Fix from Pelle Johnsen <pelle.johnsen@mail.dk>
2307 2003-04-11 Dick Porter <dick@ximian.com>
2309 * atomic.h: ARM atomic operations by Malte Hildingson
2310 <tds00mahi@tellus.thn.htu.se>
2312 Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>
2314 * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.
2316 2003-04-03 Martin Baulig <martin@ximian.com>
2318 The following change is conditional to `WITH_INCLUDED_LIBGC'
2319 which is not yet enabled by default.
2321 * threads.c (SuspendThread, ResumeThread): Fully implemented this.
2322 (gc_init): New static function; install a signal handler for
2323 SIGPWR which is used to suspend threads. [FIXME: it SIGPWR
2324 doesn't exist on all Unix systems, we need to find another
2326 (mono_wapi_push_thread_stack): New public function. Tells the
2327 garbage collector about the current stack pointer of a suspended
2330 2003-04-03 Martin Baulig <martin@ximian.com>
2332 * timed-thread.h (TimedThread): Added `suspended_sem',
2333 `suspend_count' and `stack_ptr'.
2335 2003-03-28 Dick Porter <dick@ximian.com>
2337 * atomic.h: PPC support gratiously donated to the public domain
2338 by John Duncan <jddst19@mac.com>
2340 2003-03-20 Dick Porter <dick@ximian.com>
2342 * sockets.c (_wapi_connect): If connect() fails with EACCES, try
2343 setting SO_BROADCAST and connecting again. Fixes bug 39178.
2345 2003-03-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2347 * processes.c: included Jerome Laban's patch and call SetLastError when
2348 the executable is not found.
2350 2003-03-03 Dick Porter <dick@ximian.com>
2352 * io.c (CreateFile): Try opening directories readonly, so that
2353 timestamps can be adjusted. Patch by Elan Feingold
2354 <efeingold@mn.rr.com>.
2356 2003-02-25 Dick Porter <dick@ximian.com>
2358 * shared.c (_wapi_shm_attach): Return a failure code on system
2359 call errors, rather than exiting.
2361 2003-02-21 Dick Porter <dick@ximian.com>
2363 * processes.c (GetCurrentProcessId): Use the current process
2364 handle to return the process ID, as getpid() is unreliable
2365 (linuxthreads gives each thread a different pid). Fixes bug
2368 2003-02-21 Dick Porter <dick@ximian.com>
2370 * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug
2373 2003-02-11 Dick Porter <dick@ximian.com>
2376 * timefuncs.c: Added GetTickCount()
2378 2003-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2380 * error.c: added WSA_EHOSTUNREACH mapping.
2382 2003-01-26 Miguel de Icaza <miguel@ximian.com>
2384 * io.c (SetFileAttributes): This routine is not currently
2385 implemented for the general case, but I added a special case to
2386 set the executable bit on Linux.
2388 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
2390 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
2392 2003-01-08 Dick Porter <dick@ximian.com>
2394 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
2396 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
2398 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2399 Check for an implementation which says it supports
2400 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
2401 defines the symbol. Defined but with a value of -1 still
2402 means that it is unsupported.
2404 2002-12-08 Martin Baulig <martin@ximian.com>
2406 * handles.c (_wapi_handle_new): Create new non-shared handles with
2407 an initial refcount of 1, not 0.
2409 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
2411 * threads.c (TlsGetValue): removed unnecessary mutex
2413 2002-11-20 Dick Porter <dick@ximian.com>
2415 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
2416 need to store their data structure too.
2418 * threads.c: Make sure the threading data is initialised wherever
2421 2002-11-15 Dick Porter <dick@ximian.com>
2423 * timed-thread.c: Removed unneeded parameters in
2424 _wapi_timed_thread_attach().
2426 * threads.c: Renamed AttachThread() to make it not look like
2427 external API. Removed unneeded parameters.
2429 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2431 * error.[ch]: added errno_to_WSA (). It displays a warning and return
2432 WSASYSCALLFAILURE if there is no error mapping for the given errno,
2434 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
2436 2002-10-31 Dick Porter <dick@ximian.com>
2439 * io.c: Define and use INVALID_FILE_ATTRIBUTES
2441 2002-10-07 Dick Porter <dick@ximian.com>
2444 * daemon.c: Use a more accurate time source for process start and
2447 2002-10-03 Dick Porter <dick@ximian.com>
2451 * threads.c: Fixes for freebsd. Make sure that mutex and condition
2452 creation and deletion happen in the process that owns them, when
2453 POSIX shared thread objects aren't supported. This breaks on
2454 freebsd, as pthread_t is a pointer to data.
2456 2002-10-02 Dick Porter <dick@ximian.com>
2458 * shared.c: Use mmap() instead of sysv shm for the shared data.
2460 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
2464 * daemon.c: mmap()ed regions survive fork, so just pass the
2465 pointer to _wapi_daemon_main instead of mapping it again.
2467 2002-10-01 Dick Porter <dick@ximian.com>
2469 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
2470 Unfortunately libgc uses the same thread suspend technique that I
2471 want to, and the two don't mix: libgc will deadlock when it tries
2472 to stop the world if a thread has already been suspended by
2473 someone else. Just do the simple suspended create rather than the
2474 general purpose thread suspension for now.
2476 * threads.c: Pass create flags to the timed_thread create call, to
2477 implement suspended thread creation. ResumeThread() partially
2478 implemented, to cope with the case where a newly created but
2479 suspended thread is launched.
2481 2002-09-30 Dick Porter <dick@ximian.com>
2483 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
2486 2002-09-27 Dick Porter <dick@ximian.com>
2488 * semaphores.c: Only include semaphore.h if it's present. Patch
2489 for BSD from jmmv@hispabsd.org (Julio Merino).
2491 2002-09-27 Dick Porter <dick@ximian.com>
2493 * processes.c: Pass environment and working directory to the
2494 daemon when forking. Don't let argv[0] be duplicated when looking
2495 for the program name. Implement EnumProcessModules (simple
2496 version for now, lsof-style later if needed), GetModuleBaseName,
2497 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
2498 aren't available on Linux).
2500 * process-private.h: Store the process name, and the working set
2504 * handles-private.h: New functions to store and retrieve an array
2505 of strings in the scratch space
2507 * daemon.c: Don't miss deleting some handles when a client exits
2508 (we used to rely on the client doing the final cleanup, but
2509 obviously if the client is no longer there the daemon has to do
2512 Process forking now sets the environment and the working
2515 * io.c: Don't confuse fd 0 with an unassigned handle struct
2517 * atomic.h: Add a google cache alternative to the msdn URL
2519 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2522 (_wapi_recvfrom): added ECONNRESET to the switch.
2524 2002-09-24 Mark Crichton <crichton@gimp.org>
2526 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
2529 2002-09-19 Mark Crichton <crichton@gimp.org>
2531 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
2532 dont have Linux's abstract filesystem for sockets.
2534 2002-09-19 Mark Crichton <crichton@gimp.org>
2536 * atomic.h: Added SPARC atomic asm code.
2537 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2538 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
2539 Solaris 9, however, the code paths don't seem to work. More testing
2540 on the shared case is *really* needed.
2542 2002-09-03 Dick Porter <dick@ximian.com>
2545 * threads.c: Removed PosixKillThread(), because it's not in the
2548 2002-08-20 Dick Porter <dick@ximian.com>
2550 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
2551 multiples of 4 bytes, to keep header structures aligned. Needed
2552 for sparc, at least. (Patch from crichton@gimp.org)
2554 * handles.c: Removed 'disable_shm' variable (we've defaulted to
2555 building with shm enabled for months now)
2557 2002-08-19 Dick Porter <dick@ximian.com>
2559 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
2560 for legacy NeXT-based systems.
2562 2002-08-12 Dick Porter <dick@ximian.com>
2564 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
2565 from Joseph Wenninger <kde@jowenn.at>)
2567 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
2569 * threads.c: use fast spinlocks by default
2571 2002-08-02 Dick Porter <dick@ximian.com>
2573 * io.c (GetStdHandle): Add a handle reference when returning a
2574 duplicate console handle. This fixes the unref_handle errors in
2577 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
2579 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
2582 2002-08-01 Dick Porter <dick@ximian.com>
2584 * threads.c: Use atomic spinlocks in TLS functions
2587 * Makefile.am: Added mono-spinlock.h
2589 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
2591 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
2592 these are needed for sendmsg() and also for struct msghdr (at
2593 least on Solaris). Solaris still won't build because struct msghdr
2594 doesn't have msg_flags, msg_control, or msg_controllen members.
2595 (CMSG_SPACE): Define for systems that don't have it.
2598 2002-07-20 Dick Porter <dick@ximian.com>
2604 * handles.c: Implemented pipe handles
2607 * daemon.c: Fixed bug in handle closing.
2610 * daemon.c: Forked processes now close all open file descriptors.
2612 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
2614 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
2617 2002-07-19 Martin Baulig <martin@gnome.org>
2619 * threads.c (ExitThread): Call exit() if no threads has been
2622 2002-07-17 Dick Porter <dick@ximian.com>
2624 * daemon-messages.c: Freebsd fixes from Andreas Kohn
2625 <andreas.kohn@gmx.net>
2627 2002-07-15 Dick Porter <dick@ximian.com>
2629 * io.c: Removed bogus console_flush() method, that was just cut
2630 and pasted from file_flush when I separated the two handle types.
2632 2002-07-12 Dick Porter <dick@ximian.com>
2634 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
2635 flags. Fixes bug 27633.
2637 2002-07-12 Dick Porter <dick@ximian.com>
2641 * daemon.c: Use size of sockaddr_un.sun_path from config.h
2643 2002-07-12 Dick Porter <dick@ximian.com>
2645 * processes.c (CreateProcess): Send stdin, stdout and stderr
2646 handles if the startup info doesnt specify new ones
2648 * io.c (GetStdHandle): Return the same handle when the same
2649 standard handle is requested
2651 * handles.c: Pass file descriptors when forking
2653 * daemon.c: Use supplied file descriptors when forking a new
2656 * daemon-messages.h:
2657 * daemon-messages.c: Pass stdin, stdout and stderr file
2658 descriptors to the daemon (used when forking)
2660 2002-07-11 Miguel de Icaza <miguel@ximian.com>
2662 * daemon.c (_wapi_daemon_main): Use sizeof
2663 (main_socket_address.sun_path) instead of hardcoded 108 value.
2665 * handles.c (shared_init): Use sizeof
2666 (shared_socket_address.sun_path) instead of hardcoded 108 value.
2668 2002-07-10 Dennis Haney <davh@davh.dk>
2672 * daemon.c: Lots of documentation, some added error checking, and
2673 code readability improvements.
2675 * daemon-messages.h: Add the Error request type to improve error
2678 * daemon-messages.c: Do a bit more error checking on send() and
2679 recv(), and log errors with a higher severity level.
2681 2002-07-04 Dick Porter <dick@ximian.com>
2683 * daemon.c (process_process_fork): Fix argument handling, due to
2684 buggy understanding of g_strsplit() behaviour.
2686 2002-07-03 Dick Porter <dick@ximian.com>
2689 * threads.c: Implement OpenThread(). Define access-control values
2695 * Makefile.am: Added access.h, to hold shared access-control
2698 2002-07-02 Dick Porter <dick@ximian.com>
2700 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
2702 2002-07-02 Dick Porter <dick@ximian.com>
2704 * handles.c (shared_init): Make a second attempt to contact the
2705 daemon if the shared memory attach succeeds, but the connect()
2706 fails. (This copes with the daemon crashing without cleaning up
2712 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
2713 the daemon, it's now built into the library.
2715 2002-06-25 Dick Porter <dick@ximian.com>
2718 * handles-private.h:
2719 * daemon-messages.h:
2720 * daemon.c: Process forking and handle data management
2723 * process-private.h:
2724 * processes.c: Process forking and other support functions
2726 2002-06-25 Dick Porter <dick@ximian.com>
2728 * versioninfo.h: PE resource decoding
2730 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
2731 to be told the string length
2733 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
2734 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
2737 2002-06-12 Dick Porter <dick@ximian.com>
2740 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
2741 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
2742 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
2744 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
2746 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
2747 when writing to a closed socket.
2749 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
2751 * mono-mutex.c (mono_once): New convenience function for my
2756 * critical-sections.c:
2764 * atomic.c: Use mono_once() rather than pthread_once().
2766 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
2768 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
2769 if multiple threads all try to call _wapi_handle_new() before the
2770 shared data has been initialized, it is possible that we could get
2771 into a condition where shared_init() is being executed and later
2772 threads will pass by pthread_once() due to the fact that it has
2773 already been called and so therefor will attempt to use the shared
2774 data before it has been completely initialized. If we instead use
2775 a standard mutex locking mechanism around shared_init(), we can
2776 avoid the situation entirely. By wrapping the mutex locking in a
2777 check to see if we've already initialized the data, we can even
2778 avoid wasting resources by having to lock/unlock the mutex in any
2779 later calls (the only time we'd have to worry about
2780 locking/unlocking is the initial race to call shared_init() at
2783 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
2785 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
2787 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
2789 * daemon.c, handles.c: rename "sun" local var since it's apparently
2790 a #define on Solaris.
2792 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
2794 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
2797 2002-05-15 Dick Porter <dick@ximian.com>
2799 * wait.c: Fix a deadlock in WaitForMultipleObjects
2801 2002-05-14 Dick Porter <dick@ximian.com>
2803 * io.c: Fix a cut&paste error, found by
2804 Jaroslaw Kowalski <jarek@atm.com.pl>
2806 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
2810 2002-05-09 Dick Porter <dick@ximian.com>
2816 * handles-private.h:
2818 * Makefile.am: Remove now-unused file wait-private.h
2820 2002-05-08 Dick Porter <dick@ximian.com>
2822 * shared.c: Better error messages, and report when daemon
2823 connection fails rather than blocking forever. Do some more
2824 shared memory sanity checking.
2826 * handles.c: Better error messages when connecting to shared
2827 memory and the handle daemon. Fall back to non-shared handles if
2828 an error occurs. Set the default back to 'shared handles'. Fix a
2829 crashing bug in scratch space allocation that mangled the block
2832 2002-05-07 Miguel de Icaza <miguel@ximian.com>
2834 * handles.c (shared_init): Disable SHM for now, people have too
2835 many problems with this, and the diagnostics are not helping.
2837 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
2839 * io.c: CreateFile sets win32 last error.
2841 2002-05-05 Dick Porter <dick@ximian.com>
2844 * handles-private.h:
2850 * process-private.h:
2852 * semaphore-private.h:
2856 * event-private.h: Simplify the WapiHandleOps struct: take out all
2857 the file-specific entries, leaving just the items that operate on
2858 handles themselves. Split the close operation into shared and
2859 private parts: shared close is called by the daemon.
2861 * handles.c: As above, but also pass handle allocation, ref and
2862 unref operations to the daemon. Populate the handle_ops array at
2863 compile time, because the daemon needs to call ops on handles too.
2864 Don't bother to track open handle counts any more, the daemon does
2868 * thread-private.h: As above, but also make the thread data
2871 * shared.c: Fork a handle daemon if the calling process created
2872 the shared memory segment.
2875 * daemon-messages.c:
2876 * daemon-messages.h:
2877 * Makefile.am: Build a daemon to manage handle allocation and
2878 destruction without needing to lock the shared memory
2880 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
2882 * atomic.c: Changed to use a normal mutex rather than a spinlock
2883 since a lot of platforms seem to not have them :\
2885 2002-04-30 Dick Porter <dick@ximian.com>
2887 * Completely rewrote the handle waiting code: removed the helper
2888 thread and its attendant complexity. All handle waiting is now
2889 abstracted into the WaitForSingleObject() and
2890 WaitForMultipleObjects() functions.
2892 * Implemented inter-process sharing of handles using sysv shared
2893 memory. This makes handles even more opaque, with a handle now
2894 just an index into an array.
2896 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
2898 * io.c: unitialized pointer in GetCurrentDirectory.
2900 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
2902 * threads.c: destroy the mutex at thread destruction
2903 (if/when thread destruction code will be actually called).
2904 When protecting a tls data pointer from the gc, use also the
2905 thread id in the key.
2907 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
2909 * timed-thread.c: avoid race condition when setting the thread to
2912 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2914 * jit.h: to more #include lines to avoid breaking compilation
2915 under windows when upgrading mingw and w32api to version
2918 2002-04-16 Dick Porter <dick@ximian.com>
2920 * atomic.h: Explanatory comment about lack of 80386 support
2922 2002-04-15 Dick Porter <dick@ximian.com>
2924 * atomic.h: use xaddl for InterlockedIncrement() and
2925 InterlockedDecrement(). Use cmpxchgl in a loop for
2926 InterlockedExchange() and InterlockedExchangePointer().
2928 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
2930 * unicode.c: fix unicode_len() to not access uninitialized memory
2931 (and updated to conform to mono code style).
2933 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
2935 * io.c: EEXISTS is ignored for directory creation.
2936 * mono-mutex.h: remove silly "pragma }" that emacs users insert
2937 because they use a broken editor:-)
2939 2002-03-28 Dick Porter <dick@ximian.com>
2945 * handles.c: Warning cleanups
2947 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
2949 * unicode.h, unicode.c: changed to gunichar2
2950 * io.h, io.c: changed strings to gunichar2*, added
2951 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
2952 some fixes to FindFirstFile() and friends.

2960 QueryPerformanceCounter() and QueryPerformanceFrequency()
2963 * threads.c: Implement SleepEx()
2966 * system.c: Beginnings of GetSystemInfo()
2968 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
2972 * context.c: Dummy function that doesnt yet implement
2976 * atomic.c: Interlocked functions
2978 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
2980 * threads.c: use a gc-safe hash table to store tls pointers.
2982 2002-03-22 Dick Porter <dick@ximian.com>
2984 * threads.c: Fix a race condition where a thread can start and
2985 exit before the handle has been properly initialised (no reason
2986 why the handle couldn't be initialised beforehand, so do so)
2988 Fix a ms to ns conversion magnitude thinko.
2990 2002-03-21 Dick Porter <dick@ximian.com>
2992 * semaphores.c: Fix a problem when waiting for one or more
2993 semaphores, and another semaphore is Released (all waiting
2994 semaphores assumed they were signalled)
2996 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
2998 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
2999 RemoveDirectory, GetFileAttributes, GetFileAttributesEx

3003 * threads.c (Sleep): bug fix: 1ms == 1000000ns
3005 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
3007 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
3008 threads.c, io.c: added flush method to handles.

3042 arguments for the sake of portability. Implements recursive
3043 mutexes and pthread_mutex_timedlock.
3045 * critical-sections.c:
3052 * wait.c: Use the mono-mutex wrapper portability functions/macros.
3054 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
3056 2002-01-23 Dick Porter <dick@ximian.com>

3150 will block other wait threads
3152 2001-11-11 Dick Porter <dick@ximian.com>
3154 * Makefile.am: Rename some automake variables
3155 (from Nick Drochak <ndrochak@gol.com>)
