11 * versioninfo.c (VerLanguageName): Implement VerLanguageName.
13 2008-01-31 Bill Holmes <billholmes54@gmail.com>
14 * processes.c (match_procname_to_modulename) : Added to check if the last
15 part of module name is equal to the process name.
17 * processes.c (EnumProcessModules) : Changed the first entry in the returned
18 modules array (the process module) to be populated from the entry found
21 * processes.c (get_module_name & GetModuleInformation) : In the case where
22 the module passed in is NULL, search the /proc/<PID>/maps for a name that
23 matches the process name to populate the return information.
27 2008-01-29 Zoltan Varga <vargaz@gmail.com>
29 * security.c (RevertToSelf): Make this return TRUE if impersonating is not
32 * sockets.c (_wapi_connect): Add a workaround to a solaris x86 problem where
33 getsockopt (SO_ERROR) doesn't return an error code after connect () fails. Fixes
36 2008-01-23 Dick Porter <dick@ximian.com>
38 * versioninfo.c (get_string_block): When stepping over the
39 StringTable block, do not read an extra block at the end. Fixes
40 the new part of bug 354856.
42 2008-01-19 Dick Porter <dick@ximian.com>
44 * versioninfo.c (get_stringtable_block): Cope when the StringTable

46 over it. Fixes bug 354856.
48 2008-01-16 Dick Porter <dick@ximian.com>
50 * threads.c (_wapi_thread_set_termination_details): Move the

61 * versioninfo.c (get_ptr_from_rva, scan_resource_dir): Make it
62 work on big-endian systems.
63 (scan_resource_dir): Copy the resource directory entry and
64 byteswap if necessary so it works big-endian. This fixes bug
65 345972 for real this time.
66 (VerQueryValue): String values set the length to the number of
67 unicode chars, but the data length reported was already correct so
68 don't halve it again. Fixes the previous fix for bug 345972.
69 (GetFileVersionInfo): On big-endian systems, scan the resource
70 data and turn all unicode strings into UTF-16BE. FileVersionInfo
73 2008-01-04 Dick Porter <dick@ximian.com>
75 * versioninfo.c (VerQueryValue): Returned buffer length counts
76 chars not bytes for string data. Fixes bug 345972 again.
77 (get_enclosing_section_header): Make sure values read are treated
78 as LE. Fixes crash on ppc reported in bug 345972.

82 * threads.c: Guard against a race condition involving
83 thread_hash_key that can occur during shutdown.
85 2007-12-08 Zoltan Varga <vargaz@gmail.com>

89 2007-12-06 Dick Porter <dick@ximian.com>
91 * versioninfo.c: Resource language values must be compared in a
92 'case'-insensitive manner. Fixes bug 345972.

112 /proc/<pid>/maps parsing to avoid using glib functions only
113 available since 2004.
114 (load_modules): Check for duplicates before adding a module to the
117 2007-11-15 Dick Porter <dick@ximian.com>
119 * processes.c (load_modules): Don't bother if we don't have
120 g_strsplit_set() and g_strv_length(). Allows building against old
122 (EnumProcessModules): Don't miss the first module returned by
125 2007-11-15 Dick Porter <dick@ximian.com>
127 * processes.c: Implement process module support by reading from
128 /proc if it's available.
131 * versioninfo.c: New functions to implement PE file version info

144 2007-10-26 Dick Porter <dick@ximian.com>
146 * shared.c (_wapi_shm_file_open): Set the umask when opening
147 shared files, so restrictive defaults don't prevent subsequent
148 processes re-opening them.
150 2007-10-18 Zoltan Varga <vargaz@gmail.com>
152 * atomic.h (InterlockedCompareExchange): Fix the ia64 version so it works for
153 negative values too. Hopefully fixes #332700.
155 2007-09-26 Dick Porter <dick@ximian.com>
157 * io-portability.c (_wapi_io_scandir): Only update the error
158 status of glob() when performing a secondary glob() if the first
159 returned an error. Fixes bug 325107.
161 2007-09-12 Marek Habersack <mhabersack@novell.com>
163 * io-portability.c: options_init moved to
164 utils/mono-io-portability.c
165 Do not initialize portability helpers here, it's done in
167 find_file and find_in_dir moved to utils/mono-io-portability.c

191 2007-09-03 Atsushi Enomoto <atsushi@ximian.com>
193 * processes.c, processes.h: added CreateProcessWithLogonW(). For now
194 it just calls CreateProcess().
195 * io-layer.h : CreateProcessWithLogonW() requires WINVER 0x0500
198 2007-08-23 Robert Jordan <robertj@gmx.net>
200 * processes.[c|h]: Implement Get|SetPriorityClass ().
201 Code is contributed under MIT/X11 license.

225 2007-08-10 Dick Porter <dick@ximian.com>
227 * sockets.c (_wapi_getsockopt, _wapi_setsockopt): Check the option
228 level as well as the name when mangling some of the values. Fixes
231 2007-08-02 Dick Porter <dick@ximian.com>
233 * sockets.c: Changes in error handling, and move the SO_REUSEADDR
234 setting from metadata/socket-io.c.
236 2007-08-01 Dick Porter <dick@ximian.com>
238 * io-portability.c (_wapi_io_scandir): Special-case patterns
239 ending in '.*' so that files with no extension are also matched.
243 * wapi_glob.c: Reinstate WAPI_GLOB_APPEND, and add
244 WAPI_GLOB_UNIQUE to avoid matching the same entry twice when
247 2007-07-26 Dick Porter <dick@ximian.com>
252 * critical-sections.c:
254 * critical-section-private.h:

274 Fri Jul 13 12:46:15 CEST 2007 Paolo Molaro <lupus@ximian.com>
276 * handles-private.h, handles.c, thread-private.h, threads.c,
277 uglify.h, wait.c: temporarily revert the alertable wait changes
278 (r79386) until the deadlock issues are fixed.
280 2007-06-22 Dick Porter <dick@ximian.com>
282 * shared.c: The non-shared mutexes weren't being initialised properly

287 * atomic.h: Enable for all hppa targets.
288 * Makefile.am: rename hppa_atomic.s to hppa_atomic.S so the preprocessor
290 * hppa_atomic.s: Renamed to ...
291 * hppa_atomic.S: ... and updated to work on both HPUX and Linux.
293 2007-06-13 Dick Porter <dick@ximian.com>
295 * handles.c (timedwait_signal_wait_cond): Alertable waits on
296 private handles are now interrupted by signalling the same
297 condition that would end the wait if the handle became signalled,
298 rather than polling. (Shared handles still have to poll.)
300 * threads.c (_wapi_thread_queue_apc): Interrupt the thread if it's
303 * handles-private.h (_wapi_handle_current_thread_set_waiting_on):
304 Helper functions to inform the APC queuing functions when threads
305 are waiting for handles, and to interrupt the wait.
307 * wait.c (WaitForMultipleObjectsEx): Need to tell the handle
308 waiting functions if any of the handles in question are shared
310 2007-06-06 Miguel de Icaza <miguel@novell.com>

321 * io-portability.c (_wapi_g_dir_open): Don't propagate any errors
322 from the second call to g_dir_open, preserve the original error if
323 the second call still fails but clear the error if it succeeds.
325 2007-05-10 Dick Porter <dick@ximian.com>
327 * sockets.c (_wapi_recvfrom): Refine the fix to bug 75705 so EINTR
328 isn't returned if the remote end shuts down cleanly. Fixes zmd
329 and the second example in bug 75705.
331 2007-04-26 Dick Porter <dick@ximian.com>
333 * shared.c (_wapi_shm_semaphores_init): Need to check
334 MONO_DISABLE_SHM in this entry point, as it's called before
335 _wapi_shm_attach(). Fixes bug 81436.
337 2007-04-24 Dick Porter <dick@ximian.com>
339 * sockets.c (_wapi_recvfrom, socket_close): Force recvfrom() to
340 error if the socket is closed while the receive is blocking.
343 2007-04-13 Dick Porter <dick@ximian.com>
346 * shared.c: Complete the reimplementation of disabling of shared
347 memory, by not allocating sysv semaphores when shm disabling has
348 been requested (either at compile time or run time.)
350 * processes.c (CreateProcess): Don't synchronize locking across
351 processes when forking, when shared memory has been disabled.
353 2007-04-06 Andreas Faerber <andreas.faerber@web.de>
356 * wapi_glob.c: remove reference to sys/cdefs.h, use glib instead.
359 2007-04-05 Dick Porter <dick@ximian.com>
362 * io-portability.c (_wapi_io_scandir): Moved from io.c, and
363 changed to use a cut-down version of glob(3) that has been
364 extended to match with case-insensitivity if needed.
367 * wapi_glob.c: Cut down implementation of glob(3), based on
370 2007-03-22 Dick Porter <dick@ximian.com>
372 * sockets.c (_wapi_connect): Do additional checks when connect(2)
373 fails, because some systems don't let it be restarted. Patch
374 based on one submitted by Robert S Wojciechowski <robertw@ssgx.com>,
377 2007-03-09 Jonathan Chambers <joncham@gmail.com>
379 * io-layer.h: Remove UNICODE and _UNICODE defines as
380 these are done by configure.in now.
382 Code is contributed under MIT/X11 license.
384 Thu Mar 8 19:42:17 CET 2007 Paolo Molaro <lupus@ximian.com>
386 * shared.c: partial support for MONO_DISABLE_SHM env var.
388 2007-03-05 Wade Berrier <wberrier@novell.com>
390 * atomic.h: atomic fixes from Michael Matz for for s390
391 and s390x ( bnc #237611 and bxc #80892 )
393 2007-03-05 Miguel de Icaza <miguel@novell.com>
395 * io.c (CreateFile): Use FILE_ATTRIBUTE_TEMPORARY to mean 0600
396 permissions. For 80688
398 (MoveFile): Use errno_copy here, just to avoid a potential
399 errno-changing code in the future from g_free.
401 Also, ignore EXDEV errors as they are handled immediately after
402 (avoid printing out an error).
406 Mon Feb 12 15:50:24 CET 2007 Paolo Molaro <lupus@ximian.com>
408 * shared.c: exit if semaphores can't be created (bug #80616).
410 2007-02-01 Geoff Norton <gnorton@customerdna.com>
412 * collection.c: NetBSD doesn't define PTHREAD_STACK_MIN.
414 2007-01-26 Dick Porter <dick@ximian.com>
417 * sockets.c (_wapi_getsockopt): Windows seems to not reset
418 SO_ERROR values when they're read, contrary to the documentation.
419 Fixes the new issues raised in bug 79878 (example in C showing
420 winsock behaviour attached to that bug.)
422 2007-01-15 Mark Mason <mason@broadcom.com
424 * atomic.h: add locking primitives for MIPS.
426 2007-01-11 Dick Porter <dick@ximian.com>
428 * sockets.c (_wapi_connect): Don't do the SO_BROADCAST setting
429 here, do it in managed code instead.
430 (_wapi_getsockopt): SO_RCVTIMEO and SO_SNDTIMEO use struct
431 timeval, which has a microsecond field, not milliseconds.
432 (_wapi_setsockopt): ditto.
433 (_wapi_setsockopt): Halve the SO_SNDBUF and SO_RCVBUF values on
434 Linux, as the kernel doubles whatever we set.
435 (_wapi_socket): Save socket domain, type and protocol so it can be
437 (socket_disconnect): Implement socket disconnect (closing the
438 socket, but keeping the file descriptor.)
439 (wapi_disconnectex): A basic implementation of DisconnectEx().
440 (wapi_transmitfile): A very basic implementation of
442 (WSAIoctl): Implement the SIO_GET_EXTENSION_FUNCTION_POINTER
445 * socket-private.h (struct _WapiHandle_socket): Record socket
446 domain, type and protocol info so it can be duplicated later.
448 * sockets.h (WSAID_DISCONNECTEX,WSAID_TRANSMITFILE): Structures
449 and defines needed to look up the DisconnectEx() and
450 TransmitFile() functions by GUID.
452 * error.c (errno_to_WSA): Change ETIMEDOUT mapping to
453 WSAETIMEDOUT; add EDESTADDRREQ.
455 * io-layer.h: Need mswsock.h on windows now.
457 2007-01-04 Miguel de Icaza <miguel@novell.com>
459 * io-portability.c (find_file): Fix a coverity warning (scanning
462 2006-12-31 Miguel de Icaza <miguel@novell.com>
464 * io-portability.c (find_file): Do not abort if an empty filename
465 has been passed. This fixes the case where MONO_IOMAP=all would
466 assert if Directory.Exists ("") was called.
468 Mon Dec 18 14:54:37 CET 2006 Paolo Molaro <lupus@ximian.com>
470 * processes.c: moved a free on the error path.
472 Thu Dec 14 21:42:39 CET 2006 Paolo Molaro <lupus@ximian.com>

481 2006-11-23 Dick Porter <dick@ximian.com>
483 * process-private.h (struct _WapiHandle_process): Add 'waited'
486 * processes.c (process_wait): Check the 'waited' parameter not the
487 signalled state when testing if a process has already been waited
488 for, as the child process itself may set signalled when exiting.
491 * wapi-private.h (_WAPI_HANDLE_VERSION): Bump shared data version
493 * shared.c: Now the shared data version has been incremented we
494 can set the counter semaphore initial value correctly
496 2006-11-22 Dick Porter <dick@ximian.com>
498 * processes.c (process_wait): Cope when the background process
499 reaper gets the process we were waiting for. Special case for
500 waiting for our own process to exit. Fixes bug 77736.
502 2006-11-17 Dick Porter <dick@ximian.com>
504 * processes.c: Fix const correctness and typos that caused memory
507 2006-11-17 Miguel de Icaza <miguel@novell.com>
509 * processes.c (ShellExecuteEx): Check error after CreateProcess,
510 thanks to Dick for pointing this out.
512 2006-11-16 Miguel de Icaza <miguel@novell.com>
514 * processes.c (ShellExecuteEx): If we fail to create a process in
515 ShellExecute, then try to use the xdg-open command, and if that
516 fails, try to use the gnome-open command,
518 Refactor the code so that we do not have to duplicate all this
519 code, but instead use a ucs2-aware version of the code to do
522 2006-11-13 Dick Porter <dick@ximian.com>
524 * io.c (_wapi_stat_to_file_attributes): If the file is a symlink
525 add the FILE_ATTRIBUTE_REPARSE_POINT flag. This is an attempt to
526 follow the specs for the windows symlink support, but will
527 probably have to be reworked when I have test data from a vista
528 machine. Fixes bug 79887.
530 2006-11-11 Miguel de Icaza <miguel@novell.com>
532 * handles.c (CloseHandle): Cope here with the new value
533 INVALID_HANDLE_VALUE set on handles.
535 * processes.c (CreateProcess): Initialize the value of hThread to
536 be INVALID_HANDLE_VALUE on failure, not to be NULL. Improvement
539 2006-11-09 Dick Porter <dick@ximian.com>
541 * sockets.c (_wapi_select): Do some sanity checking on the
542 fd_sets, to avoid file descriptors > FD_SETSIZE.
543 (_wapi_FD_CLR, _wapi_FD_ISSET, _wapi_FD_SET): Avoid file
544 descriptors > FD_SETSIZE.
546 2006-10-27 Dick Porter <dick@ximian.com>
548 * io.c (GetFileAttributes): Force symlinks to directories to be
549 returned as a regular file. Fixes bug 79733.
551 2006-10-18 Miguel de Icaza <miguel@novell.com>
553 * io-portability.c (find_in_dir): First string dup, then closedir.
555 2006-10-12 Dick Porter <dick@ximian.com>
557 * processes.c (_wapi_process_reap): Unref a process handle if we
558 reaped it, found by Zoltan. Fixes bug 79286.
559 (process_wait): Don't wait again if we've already waited for a
562 2006-10-11 Sergey Tikhonov <tsv@solvo.ru>
564 * atomic.h: Fix atomic decrement.
566 * mini/cpu-alpha.md: Use native long shift insts

578 2006-10-09 Zoltan Varga <vargaz@gmail.com>
580 * handles.c (timedwait_signal_poll_cond): Add an alertable parameter, and if it
581 is FALSE, avoid busy waiting.
583 * wait.c: Add an alertable parameter to the wait routines.
585 2006-10-06 Miguel de Icaza <miguel@novell.com>
587 * io-portability.c (find_file): Rename from
588 MONO_IO_PORTABILITY_HELP to MONO_IOMAP.
590 2006-10-03 Dick Porter <dick@ximian.com>
593 * io-portability.c: Optional portability helpers and wrapped
594 system calls to try to cope with windows filenames in
597 * io.c: Use the wrapped system calls
599 2006-09-01 Zoltan Varga <vargaz@gmail.com>
601 * critical-sections.h critical-sections.c: Make Enter/LeaveCriticalSection a macro
602 since they are perf critical.
604 * atomic.h: Applied patch from Jakub Boqusz <qboosh@pld-linux.org>.
605 Add atomic ops implementation for alpha.
607 2006-08-11 Dick Porter <dick@ximian.com>
609 * processes.c (_wapi_process_reap): Avoid a deadlock by setting
610 process termination details in an outer loop, not the
611 _wapi_search_handle() one.
613 2006-08-10 Dick Porter <dick@ximian.com>
615 * threads.c (_wapi_thread_queue_apc)
616 (_wapi_thread_dispatch_apc_queue): Use a process-local mutex here
617 instead of the cross process semaphore. We already check that
618 access to the APC queue is within the owning process so there's no
619 need to protect from other processes. Avoids a global deadlock
620 when a thread is aborted while it holds the handle semaphore
622 (_wapi_thread_apc_pending): Hide an annoying message which can
623 happen if a thread handle has been blown away at process shutdown
624 while it is in an alertable wait.
626 Both problems seen while shutting down monodevelop.
628 2006-07-25 Dick Porter <dick@ximian.com>
630 * shared.c (_wapi_shm_file): Remove '/' characters from the uname
631 results. Fixes bug 78917.
633 2006-07-20 Dick Porter <dick@ximian.com>
635 * threads.c (_wapi_thread_set_termination_details): Improve the
636 test for already-disposed thread handles, and hold the lock around
637 the mutex abandoning.
639 2006-07-17 Dick Porter <dick@ximian.com>
641 * processes.c (CreateProcess): Don't change directory unless a new
642 one has been specified. Fixes bug 78751.
644 2006-07-06 Dick Porter <dick@ximian.com>
646 * io.c (_wapi_stat_to_file_attributes): Do a better job at
647 figuring out the file attributes
648 (_wapi_set_last_path_error_from_errno): New helper function to
649 turn errno into w32 error codes that handles the differences
650 between file and directory errors
651 (file_setendoffile): Try turning off the extra write used to
652 extend files, because we probably don't need it on any modern
653 platform. If it is needed though, we also need to lseek the file
655 (CreateFile): Treat character-special devices as a console handle,
656 because they can't be seeked
657 (CopyFile): If fail_if_exists is set, then the destination needs
658 to be opened with O_EXCL
659 (CopyFile): If fail_if_exists is not set and the destination
660 already exists, then we should set the ERROR_ALREADY_EXISTS error
661 even though we return success
662 (stdhandle_create): STD_INPUT_HANDLES cannot be written to
663 (GetStdHandle): Rework without using mono_once, so console handles
664 can be properly closed and reopened.
665 (mono_io_scandir): Only override errno with EACCES when the
666 directory actually exists
667 (FindFirstFile): Set ERROR_FILE_NOT_FOUND when no files are
669 (FindClose): Cope with NULL handles
670 (CreateDirectory): When the target already exists, just return an
671 error. It's the caller's job to figure out what to do.
672 (SetCurrentDirectory): Cope with a NULL path
673 (RemoveDirectory, GetFileAttributes, GetFileAttributesEx,
674 SetFileAttributes, FindFirstFile, DeleteFile, MoveFile, CopyFile,
675 CreateFile): Set path error correctly
677 * handles.c (CloseHandle): Kludge to try and cope with passing a
680 * error.h: Add NO_ERROR as an alternative to ERROR_SUCCESS
682 * uglify.h: Added some more typedefs
684 2006-07-05 Dick Porter <dick@ximian.com>
686 * io.c (GetFileAttributes, GetFileAttributesEx): Cope with
687 dangling symlinks. Fixes bug 78664.
689 2006-06-23 Dick Porter <dick@ximian.com>
691 * handles.c (handle_cleanup):
692 * threads.c: Clean up threads properly when we're forcibly
693 removing the handle entries from the shared file in
694 handle_cleanup(). Fixes bug 78241, for real this time.
696 2006-06-15 Neale Ferguson <neale@sinenomine.net>
698 * atomic.h: More tinkering with InterlockedExchange/InterlockedCompareExchange
701 2006-06-14 Neale Ferguson <neale@sinenomine.net>
703 * atomic.h: Fix atomic exchange pointer operations for s390x - these
704 were broken as they used 32-bit instructions rather than their 64-bit
707 2006-06-14 Dick Porter <dick@ximian.com>
709 * processes.c: Don't run the atexit handlers when bailing out
712 2006-06-14 Dick Porter <dick@ximian.com>
714 * wait.c: Fix stupid typo shown up by gcc 4.1.1, = not ==
722 * collection.c: Fix a bunch of signed/unsigned warnings from gcc
725 2006-06-09 Neale Ferguson <neale@sinenomine.net>
727 * atomic.h: Fix atomic operations for s390x (not really broken
728 but changed to use full 64-bit opcodes).
730 2006-05-24 Dick Porter <dick@ximian.com>
732 * processes.c (process_set_current): Don't take an extra reference
733 if we have to create our own process handle. Fixes bug 78241
736 * threads.c (_wapi_thread_signal_self): Renamed from
737 _wapi_thread_abandon_mutexes, also sets the thread state to
738 signalled and drops a reference. Called by the runtime when the
739 main thread cleans itself up.
741 * handles.c (handle_cleanup): As a last resort, unref every shared
742 handle as the process is now exiting.
744 2006-05-16 Dick Porter <dick@ximian.com>
746 * processes.c (process_set_termination_details): Unref the handle
747 when we've stored the exit details. Fixes the rest of 78241.
749 2006-05-12 Dick Porter <dick@ximian.com>
751 * threads.c: Implement pseudo handles, making GetCurrentThread()
752 match MS behaviour. Notice when attached threads exit, and unref
753 the handle. Fix usage of GetCurrentThread() in other places.
755 * handles.c (DuplicateHandle): Implement a basic form of
758 * wait.c: Fix usage of GetCurrentThread() throughout, and cope
761 2006-04-26 Miguel de Icaza <miguel@novell.com>
763 * io.c (file_close): Oops, do not use DeleteFile which expects
764 unicode, instead use unlink directly
766 Add support for the new FileOptions bits on .NET 2.0.
768 It might be good if Dick reviews these changes.
770 * io.c (file_close): If DeleteOnClose is set, then delete the file
772 (CreateFile): Do not support encryption per user.
774 If posix_fadvise exists, pass hints on sequential scan and random
775 access. Did not figure out what WRITE_THROUGH maps to.
777 2006-04-26 Dick Porter <dick@ximian.com>
779 * sockets.c (WSAIoctl): Check the output buffer is valid before
782 * handles.c (_wapi_search_handle): Set shared pointer if we find a
783 shared handle that has been already opened.
785 2006-04-21 Dick Porter <dick@ximian.com>
787 * threads.c (GetCurrentThread): Reference the handle if we return
788 an already-known thread.
790 2006-04-07 Dick Porter <dick@ximian.com>
792 * processes.c: Fix build for older glib.
794 2006-04-06 Dick Porter <dick@ximian.com>
796 * processes.c (CreateProcess): Add a reference to the child
797 process' handle, so it won't be destroyed if this process closes
798 its copy of the handle. Fixes bug 77393.
800 * processes.c (process_set_current): Fall through to creating a
801 new one if the handle lookup fails.
803 * processes.c (_wapi_process_signal_self):
804 * handles.c (handle_cleanup): The process is exiting, so set the
805 handle state for this process to signalled. This should let other
806 non-related processes wait for this handle.
808 * handles.c (_wapi_search_handle): Don't search shared handles in
811 * collection.c (collection_thread): No need to do a collection
812 scan straight away, do the waiting first.
814 2006-04-06 Dick Porter <dick@ximian.com>
816 * shared.c: Fix parameters in semctl () call.
818 2006-03-28 Zoltan Varga <vargaz@gmail.com>
820 * atomic.h atomic.c: Applied patch from David S. Miller
821 <davem@davemloft.net>: Reimplement Interlocked* primitives on sparc
822 using CAS/CASx when __GNUC__, else we will fall back to the generic
825 2006-03-27 Dick Porter <dick@ximian.com>
827 * shared.c (_wapi_shm_file_open): Break out of a loop if the
828 shared file is smaller than expected. (We loop a few times in
829 case another process is in the middle of creating the file.)
831 2006-03-22 Dick Porter <dick@ximian.com>
836 * shared.c: Delete the semaphores and shared files when the last
837 process has finished with them
839 2006-03-15 Dick Porter <dick@ximian.com>
847 * threads.c: Explicitly initialise the handle ops struct
849 2006-03-14 Dick Porter <dick@ximian.com>
854 * handles.c: Add a 'prewait' stage to the handle waiting, to give
855 waiting threads a chance to check for bogus states before
858 * mutexes.c (namedmutex_prewait): Use the prewait stage to check
859 for named mutexes that have been abandoned in a locked state (eg
860 if a process exited abnormally while owning the mutex) and
861 override it if needed.
863 2006-03-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
865 * wait.c: speed up WaitFor* when the timeout is 0.
867 2006-03-03 Dick Porter <dick@ximian.com>
869 * processes.c (ShellExecuteEx): Cope when some of the parameters
872 2006-02-27 Dick Porter <dick@ximian.com>
876 * threads.c: Comparing pthread_t with == is not portable, so use
879 Thu Feb 23 18:47:20 GMT 2006 Paolo Molaro <lupus@ximian.com>
881 * *.h, *.h: patch from Dick to make Linuxthreads systems work again.
883 2006-02-22 Dick Porter <dick@ximian.com>
886 * threads.c: There's no need to use the timed-thread support code
887 any more, as we aren't using the timed join. This greatly
888 simplifies thread setup, and fixes a memory leak (bug 77521).
890 Don't bother to store thread IDs in a hash table, use TLS instead.
891 The one case that needs to look up the handle of a different
892 thread (OpenThread()) can do the extra work itself. Fixes bug
895 * handles.c (_wapi_search_handle): Add a reference when returning
896 a private handle (shared handles are already reffed.)
898 2006-02-17 Dick Porter <dick@ximian.com>
901 * handles.c: Check handle values passed to array lookups. Fixes
904 2006-02-09 Dick Porter <dick@ximian.com>
906 * threads.c: Cope with the problems caused by attaching already
907 existing threads - they don't get the infrastructure to clean up
908 after themselves, especially the ID to handle hash. This fixes
911 2006-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
913 * shared.c: use MONO_SHARED_HOSTNAME as a substitute for gethostname()
914 when creating the shared files in the .wapi directory. Fixes bug #77371.
916 2006-02-02 Martin Baulig <martin@ximian.com>
918 * threads.c: Removed the `WITH_INCLUDED_LIBGC' section; it has
919 never been used so far.
921 * timed-thread.h (TimedThread): Removed the `stack_ptr' field; it
922 has only been used by the removed code.
924 2006-01-03 Neale Ferguson <neale@sinenomine.net>
926 * atomic.h: Correct s390x definitions and eliminate compiler warnings.
928 2006-01-03 Sebastien Pouliot <sebastien@ximian.com>
930 * io.c: Patch _wapi_stat_to_file_attributes against bug #76966, where
931 sockets could be considered as directory.
933 2005-12-23 Dick Porter <dick@ximian.com>
937 * semaphores.c: Implement OpenSemaphore
940 * mutexes.h: Implement OpenMutex
946 * event-private.h: Implement named events. Implement OpenEvent.
948 2005-12-15 Dick Porter <dick@ximian.com>
950 * processes.c (CreateProcess): The pipe-based cross-process
951 exclusion technique was trying to write NULL buffers when appname
952 was NULL (eg when coming from ShellExecuteEx,) which usually
953 succeeded even though EFAULT was returned - but sometimes it
954 failed. This meant that the child process could block forever on
955 the pipe read. Replace it with the simpler shared handle
956 semaphore protection used everywhere else. This showed up with
957 the test case in bug 76684.
959 Tue Dec 13 11:41:49 GMT 2005 Paolo Molaro <lupus@ximian.com>
961 * shared.c: fallback to private mmap when shared mmap doesn't work
964 2005-12-06 Dick Porter <dick@ximian.com>
968 * semaphore-private.h:
969 * semaphores.c: Implement named semaphores
971 2005-11-24 Dick Porter <dick@ximian.com>
973 * processes.c (GetProcessId): Implement GetProcessId()
975 2005-11-17 Dick Porter <dick@ximian.com>
978 * processes.c: Implement ShellExecuteEx as a wrapper around
981 2005-11-11 Dick Porter <dick@ximian.com>
983 * threads.c: Give mutex abandoning its own exported function, so
984 it can be called when the runtime is cleaning up.
986 * handles.c (_wapi_search_handle_namespace): Do a handle
987 collection befre starting to check namespace strings, so that any
988 stale cruft gets removed.
990 2005-11-11 Dick Porter <dick@ximian.com>
992 * threads.c: Move thread handles back into the shared space.
994 * handles.c (_wapi_handle_unref): Add support for shared handles
995 with close() handlers
997 2005-11-04 Dick Porter <dick@ximian.com>
999 * sockets.c (ioctlsocket): Use select instead of if to avoid a
1000 type promotion problem on 64bit freebsd. Based on patch by Lou
1001 Kamenov <kamenovl@gmail.com>, fixes bug 76447.
1003 2005-11-04 Dick Porter <dick@ximian.com>
1005 * io.c (file_write): Only do the file locking if
1006 MONO_STRICT_IO_EMULATION is set.
1008 2005-10-21 Dick Porter <dick@ximian.com>
1011 * handles.c (_wapi_lookup_handle): Cope when the shared part of a
1012 handle has been deleted.
1013 (_wapi_handle_unref): And when the deleted shared part is pointed
1014 to as a handle is deleted
1016 2005-10-20 Dick Porter <dick@ximian.com>
1018 * processes.c (process_set_current): If the expected process
1019 handle slot doesn't contain the correct pid, create a new handle.
1021 * handles.c (_wapi_search_handle): When the search doesn't find
1022 anything, return failure instead of the last handle we looked at.
1023 (_wapi_handle_ref, _wapi_handle_unref): Don't try to ref or unref
1024 unused handles (makes tracking refcounting bugs easier.)
1026 2005-10-19 Dick Porter <dick@ximian.com>
1029 * handles-private.h:
1033 * collection.c (_wapi_handle_collect): Remove the shared handle
1034 indirection layer, and use locking instead. Delete other
1035 complexity that is no longer needed. Refcount shared handles and
1036 delete them when needed, but keep the timestamps so that orphaned
1037 handles will be cleaned up eventually.
1039 * shared.c (_wapi_shm_file): Add processor, OS and struct size
1040 info to the shared file names, to cope with dual-boot and 32/64bit
1041 size issues. Fixes bug 75839.
1043 * wait.c (WaitForMultipleObjectsEx): No need to distinguish
1044 between shared handles and private, as the wait functions cope
1045 with both together now.
1047 2005-10-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1049 * io.c: removed NO_SIGPIPE macro.
1050 * sockets.c: no need for MSG_NOSIGNAL or ignoring SIGPIPE.
1052 2005-10-11 Dick Porter <dick@ximian.com>
1054 * sockets.c (_wapi_getsockopt): Translate SO_ERROR results into
1057 * error.c (errno_to_WSA): Don't return a bogus error if someone
1058 asks to translate errno 0.
1060 2005-10-11 Dick Porter <dick@ximian.com>
1062 * handles.c: Fix several race conditions
1064 2005-10-11 Miguel de Icaza <miguel@novell.com>
1066 * io.c: no need to block SIGPIPE anymore, as it is ignored.
1068 2005-10-05 Dick Porter <dick@ximian.com>
1070 * threads.c (_wapi_thread_own_mutex, _wapi_thread_disown_mutex):
1071 Keep a reference to mutexes owned by threads, so they won't be
1072 destroyed prematurely. Fixes dotmsnclient crash.
1074 2005-09-26 Sebastien Pouliot <sebastien@ximian.com>
1076 * io.c: Apply patch from #76192 (Can't write files past 2gb on AMD64
1077 (x86_64)) for Brion on IRC (Dick approved it).
1079 2005-09-23 Dick Porter <dick@ximian.com>
1081 * processes.c: Don't wait for processes that have already been
1082 signalled; also fix typo.
1084 * handles.c: Improve locking inside new handle and handle
1085 searching functions.
1087 2005-09-20 Dick Porter <dick@ximian.com>
1090 * processes.c: Periodically waitpid for known process IDs. Fixes
1093 2005-09-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1096 (CreateFile): if the file is a named pipe, treat the handle as a pipe,
1097 not as a file. Fixes bug #76075.
1099 2005-08-27 Zoltan Varga <vargaz@gmail.com>
1101 * atomic.h: Add support for intel icc.
1103 2005-08-25 Zoltan Varga <vargaz@gmail.com>
1105 * io-layer.h: Include winbase.h not WinBase.h.
1107 2005-08-19 Dick Porter <dick@ximian.com>
1109 * threads.c, threads.h, thread-private.h: Use a gsize to store the
1110 thread ID, so it can hold a 64 bit value if needed.
1112 2005-07-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1114 * error.c: map ENOENT to WSAECONNREFUSED. It might happen when
1115 connecting to unix sockets. Closes bug #75632.
1117 2005-07-05 Dick Porter <dick@ximian.com>
1119 * io.c: Make sure SIGPIPE is ignored when calling write(2).
1120 Prevents the runtime exiting when writing to a closed pipe,
1123 2005-06-30 Dick Porter <dick@ximian.com>
1125 * shared.c (_wapi_shm_semaphores_init): Add some helpful error
1126 messages when semget () fails due to lack of resources.
1128 2005-06-21 Dick Porter <dick@ximian.com>
1133 * threads.c: Keep a list of owned mutexes in each thread handle,
1134 so that it is easier to abandon them when the thread exits.
1135 Removes a bottleneck when multiple threads are finishing in
1138 2005-06-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1140 * io.c: (GetLogicalDrives) when a bogus line is read, don't leak memory.
1141 When the buffer has not enough space, close the file before returning.
1143 2005-06-09 Duncan Mak <duncan@novell.com>
1145 * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to
1146 all public headers. Fixes #74919.
1148 2005-05-30 Zoltan Varga <vargaz@freemail.hu>
1150 * atomic.h: Add IA64 atomic ops.
1152 2005-05-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1154 * processes.c: make ExitCode be valid even if the user didn't call
1155 WaitForExit() and is just polling on HasExited.
1157 2005-05-17 Dick Porter <dick@ximian.com>
1159 * io.c (file_getfilesize): Clear the error value, so that files
1160 with sizes with the low bits 0xFFFFFFFF can be distinguished from
1163 2005-05-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1165 * shared.c: forgot to ignore a warning.
1167 2005-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1169 * shared.c: don't display warnings after reboots.
1171 2005-05-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1173 * sockets.c: on windows, getsockopt/setsockopt for send/receive timeout
1174 use an integer in milliseconds. We were using a struct timeval.
1176 2005-05-06 Dick Porter <dick@ximian.com>
1178 * handles-private.h:
1185 * collection.h: Use SysV semaphores for managing access to the
1186 shared memory - in return for the ludicrous api we get
1187 synchronisation primitives that can be cleaned up by the kernel
1188 even when a process quits unexpectedly. This removes the
1191 2005-05-05 Lluis Sanchez Gual <lluis@novell.com>
1193 * handles.c: Always use polling in the waits, since
1194 mono_cond_timedwait can't be interruped by the thread abort signal.
1196 2005-04-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1198 * events.c: calling Set on AutoResetEvent several times has the same
1199 effect as calling it only once if no thread is waiting for it.
1201 2005-04-29 Dick Porter <dick@ximian.com>
1203 * processes.c (EnumProcesses): Use a GArray instead of a GPtrArray
1204 now it's storing pids not handles, also fixes memory leak caused
1205 by unclear glib documentation.
1207 * sockets.c (WSACleanup): Remove unused variable
1209 2005-04-29 Dick Porter <dick@ximian.com>
1211 * handles.c (_wapi_handle_check_share_by_pid): For systems that
1212 don't have file descriptor info in /proc check that the original
1213 opener of a file is still there, if a share violation would
1216 2005-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1219 * handles-private.h: added _wapi_handle_forecch that loops through all
1220 the handles and call a callback function when a handle of the given
1223 * sockets.c: no need to keep open sockets in an array, as we have them
1224 in the handles structure.
1228 2005-04-28 Dick Porter <dick@ximian.com>
1230 * processes.c: Cope with handles that are only around for as long
1231 as the search is running. If we're searching for process handles,
1232 check to see if the process is still running and signal it if not.
1234 * handles.c (_wapi_search_handle): Search in the shared space as
1235 well. Fixed bug 74752.
1238 * handles.c (_wapi_handle_new_from_offset):
1239 _wapi_handle_new_for_existing_ns () was doing exactly the same as
1240 this, so deleted it.
1242 2005-04-26 Dick Porter <dick@ximian.com>
1244 * handles.c: Fix stupid thinko where if a new shared handle is
1245 created but a collection was needed to free some space, it
1246 returned an error anyway. Should fix the messages shown in bug
1249 2005-04-25 Dick Porter <dick@ximian.com>
1251 * handles.c (_wapi_handle_check_share): Only consider mono
1252 processes when looking to see if a file is still being held open,
1253 while checking share permissions.
1255 2005-04-25 Dick Porter <dick@ximian.com>
1259 * wapi-private.h (struct _WapiHandleOps):
1260 * handles.c (_wapi_handle_unref): When destroying handles, save
1261 the handle data and call the close function only after the array
1262 slot has been cleared. This prevents race conditions with file
1263 descriptors, fixing bug 74713.
1265 * mutexes.c: Delete the handle close functions, they didn't do
1268 * error.c (_wapi_get_win32_file_error): Add a mapping for EINTR so
1269 the "Unknown error" g_warning doesn't get displayed.
1271 2005-04-25 Dick Porter <dick@ximian.com>
1274 * threads.c: Make thread handles process-private for now to take
1275 some of the space pressure off the shared memory, while I work on
1278 2005-04-21 Dick Porter <dick@ximian.com>
1280 * handles.c (_wapi_handle_check_share): Make sure there is a "fd"
1281 dir in /proc before blowing away handle info. Fixes bug 74649.
1283 2005-04-21 Dick Porter <dick@ximian.com>
1285 * wait.c (WaitForMultipleObjectsEx): Implement special waits
1287 * handles.c (_wapi_handle_wait_signal_poll_share): Don't return a
1288 timeout, just wait briefly for the private signals and let the
1289 waiting thread test again. This prevents us missing shared
1292 2005-04-21 Dick Porter <dick@ximian.com>
1294 * collection.h (_WAPI_HANDLE_COLLECTION_EXPIRED_INTERVAL): Reduce
1295 the time before a slot is considered too old and deleted. This is
1296 a workaround while I come up with a proper fix.
1298 2005-04-21 Dick Porter <dick@ximian.com>
1303 * handles.c (_wapi_handle_new): Turn assertions into errors.
1305 * collection.c (_wapi_handle_collect): Use symbols not magic
1306 numbers for timeout values
1308 2005-04-19 Dick Porter <dick@ximian.com>
1312 * handles.c (_wapi_handle_count_signalled_handles)
1313 * handles-private.h (_wapi_handle_shared_lock_handle): Use new
1314 shared handle locks in critical sections.
1316 * handles.c (_wapi_handle_new_for_existing_ns): Reuse old handles
1317 if there is already one there.
1319 * handles.c (_wapi_handle_ref): It was possible for a process to
1320 exit before getting around to updating shared handle timestamps,
1323 Tue Apr 19 16:25:47 CEST 2005 Paolo Molaro <lupus@ximian.com>
1325 * threads.c: fix lookup of the thread id in the has table:
1326 always use the id value, not the pointer to the id.
1328 2005-04-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1330 * handles.c: fix handle returned in _wapi_handle_search_handle. Dick
1333 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1335 * io-layer/sockets.c: FIONBIO with a TRUE argument means we want
1336 non-blocking IO, not the other way around.
1338 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1342 * handles-private.h: GetFileType wasn't checking if we have memory
1343 allocated for the handle before dereferencing it. Fixes a FileStream
1346 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1350 * handles-private.h: we were calling g_renew to expand the handle array,
1351 but that might move the memory and we might have pthread conditions or
1352 mutexes in the original memory area that are being used. Now instead of
1353 expanding an existing array, we just create new ones and keep a list of
1354 them. Access to _wapi_private_handles had to be modified accordingly.
1356 2005-04-15 Dick Porter <dick@ximian.com>
1358 * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN
1360 2005-04-14 Raja R Harinath <rharinath@novell.com>
1362 * wapi-private.h: Remove reference to 'daemon-private.h'.
1364 Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro <lupus@ximian.com>
1366 * atomic.h: applied patch from mass@akuma.org (David Waite)
1367 to fix InterlockedExchangeAdd.
1368 Fixed a few other functions, including InterlockedCompareExchange()
1369 which was miscompiled by gcc with optimizations enabled.
1371 2005-04-13 Dick Porter <dick@ximian.com>
1373 * io.c (share_check):
1374 * handles.c (_wapi_handle_check_share): Refine the file check so
1375 that sharing violations within the same process don't cause
1378 2005-04-13 Dick Porter <dick@ximian.com>
1380 * io.c (FindFirstFile): Fix bugs introduced with the merge (bug
1383 2005-04-12 Dick Porter <dick@ximian.com>
1385 The daemon-less io-layer. Extensive lowlevel changes in
1386 handles.c, requiring some corresponding changes in other files
1387 calling these functions. Private_foo structures have been
1390 File descriptor handling differences account for most of the
1391 changes in io.c and sockets.c.
1395 * mutexes.c: Named mutexes are now a distinct type.
1396 * atomic.h: Fix a PPC uninitialised variable warning.
1397 * wait.c: Check conditions before waiting on a condition variable.
1398 * processes.c: Handle process fork and wait without a daemon
1399 (though this has the limitation of only being able to wait for
1402 2005-04-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1409 * sockets.h: removed dead code that deals with async IO.
1411 2005-03-30 Zoltan Varga <vargaz@freemail.hu>
1413 * atomic.c (InterlockedIncrement): Fix fallback implementation of
1414 InterlockedIncrement and InterlockedDecrement. Fixes #74228.
1416 2005-03-29 Sebastien Pouliot <sebastien@ximian.com>
1418 * io-layer.h: Add required header files for compiling with VS.NET.
1420 2005-03-17 Miguel de Icaza <miguel@novell.com>
1422 * io.c: don't fail on NFS when there are no more locks available.
1424 2005-03-09 Dick Porter <dick@ximian.com>
1426 * error.c (_wapi_get_win32_file_error): ENFILE and EMFILE should
1427 map to ERROR_TOO_MANY_OPEN_FILES, not ERROR_NO_MORE_FILES. Fixes
1430 2005-03-09 Dick Porter <dick@ximian.com>
1432 * daemon.c (process_process_fork): Initialise the handle data
1433 before using it in the error case. This is probably the error
1434 we're working around in the previous change. Spotted by Taru Jain
1435 <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.
1437 2005-03-07 Dick Porter <dick@ximian.com>
1439 * daemon.c: It looks like g_shell_parse_argv() can return
1440 argv[0]=NULL somehow, yet still not give an error. Make sure we
1441 don't pass NULL to strrchr(), working around a segfault that
1442 showed up on ZLM testing.
1444 2005-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1446 * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is
1447 the expected error code showed by the test case in bug #73053.
1449 2005-02-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1451 * io.c: another leftover.
1453 Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1455 * io.c: fixed logic in checking errno in rev 40815.
1457 Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1459 * threads.c: we don't depend on the GC checking tls
1461 * processes.c: remove unused ref to GC headers.
1463 Thu Feb 17 19:57:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1465 * io.c: remove _wapi_thread_cur_apc_pending () checks
1466 when the siscall should return immediatly and handle
1467 the case when a syscall is interrupted without
1468 erroring out, but returning a 0 read/write if possible.
1469 Still the cases of read from file need to be handled.
1471 Tue Feb 8 18:28:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1473 * threads.c: make people test with 1 MB stack per thread.
1475 2005-01-17 Dick Porter <dick@ximian.com>
1477 * timefuncs.h: Make WapiFileTime endian-aware, as it's often
1478 cast to and from 64bit ints. Fixes bug 71213.
1480 2005-01-11 Dick Porter <dick@ximian.com>
1482 * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
1485 Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>
1487 * atomic.h: Fix functions on s390.
1489 Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>
1491 * atomic.h: fix some functions on ppc (tests/interlocked.cs).
1493 2005-01-10 Dick Porter <dick@ximian.com>
1495 * misc.c (_wapi_calc_timeout): Guard against overflow when
1496 calculating timeouts. This makes waiting with a large
1497 (Int32.MaxValue) timeout not return immediately.
1499 2004-12-23 Ben Maurer <bmaurer@ximian.com>
1501 * io.c (io_ops): make this `const' so it is shareable (well, only
1502 really shareable if it is statically linked...)
1504 Mon Dec 20 11:58:33 CET 2004 Paolo Molaro <lupus@ximian.com>
1506 * threads.c, threads.h: add accessor to get the pthread_key_t for
1509 2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1511 * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS
1512 if it exists and is not the same as 'src'.
1514 2004-12-01 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1516 * atomic.h : Fix InterlockedCompareExchange for s390/s390x.
1518 2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1520 * processes.c: unquote the cmd path, allow for ' or " when quoting and
1521 pass the quoted program name to the daemon, otherwise the call to
1522 g_shell_unquote in the daemon will break things up.
1524 2004-10-14 Dick Porter <dick@ximian.com>
1526 * sockets.c (_wapi_accept): Revert the previous change. We now
1527 set the accepted socket to have the same blocking status as the
1528 listening socket in managed code. This follows MS behaviour.
1530 2004-10-14 Dick Porter <dick@ximian.com>
1532 * sockets.c (_wapi_accept): On Darwin, make sure a newly
1533 accept()ed socket is blocking. Fixes bug 67355, patch by
1534 grompf@sublimeintervention.com.
1536 2004-10-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1538 * system.c: check the number of online processors instead of the
1539 existing ones. Sanitize return value if it's an error.
1541 2004-10-03 Ben Maurer <bmaurer@ximian.com>
1543 * system.c: Add support for getting the # of cpus.
1545 2004-09-28 Dick Porter <dick@ximian.com>
1547 * io.c (pipe_close_private): Fix one small typo in the last change
1548 that totally hosed process creation with redirected pipes.
1550 2004-09-24 Dick Porter <dick@ximian.com>
1557 * handles-private.h: Cope when a file descriptor is reused while
1558 the handle that thought it owned it is still referenced, instead
1559 of asserting. Probably fixes bug 66479, though we've been unable
1562 2004-09-09 Dick Porter <dick@ximian.com>
1565 * io.c: Set error codes everywhere.
1567 2004-09-06 Dick Porter <dick@ximian.com>
1569 * handles.c (_wapi_handle_unref): Reset the private record's type
1570 (CloseHandle): Check for a fd mapping failure, and return FALSE.
1571 (_wapi_handle_process_fork): Fix long-standing bug in checking
1572 handle return values. Also do the required bookkeeping with the
1573 new process's handles.
1575 * daemon.c: When creating a new process's handles, check whether
1576 the shared space needs to be increased
1578 2004-09-05 Zoltan Varga <vargaz@freemail.hu>
1580 * shared.c (_wapi_shm_file): Fix leaking of filename.
1582 2004-08-19 Dick Porter <dick@ximian.com>
1584 * handles.c (_wapi_handle_count_signalled_handles): Fix thinko
1585 introduced with the fd offset stuff: unlock handles properly when
1586 backing off. Fixes the monologue hang at exit.
1588 2004-08-18 Dick Porter <dick@ximian.com>
1591 * io.c: Check that new fds fit in the table, return error if not
1593 * daemon.c (_wapi_daemon_main):
1594 * handles.c (shared_init): Have all processes agree on a size for
1597 2004-08-17 Dick Porter <dick@ximian.com>
1599 * daemon.c (process_new):
1600 * handles.c (_wapi_handle_new_internal): Cope when the space
1601 reserved for file descriptors is larger than the shared segment
1602 size. Fixes the crash reported when running mono under gdb on
1605 2004-08-16 Dick Porter <dick@ximian.com>
1609 * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
1610 error checking with passed-in file descriptors.
1612 2004-08-11 Dick Porter <dick@ximian.com>
1615 * io.c: Returned handle values are the file descriptor the handle
1619 * handles-private.h:
1620 * daemon.c: Reserve the range of handles that can have the same
1621 values as file descriptors. These won't be used, but the values
1622 will be used as file, console, pipe or socket handles. The fd to
1623 handle mapping is done internally and is invisible to users.
1626 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
1627 reserve a chunk of handle space.
1629 2004-08-04 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1631 * atomic.h: add support for 64-bit S/390
1633 2004-07-22 Dick Porter <dick@ximian.com>
1636 * threads.c: Move the destruction of the internal thread data to
1637 after the thread has been joined. Fixes bug 61418.
1639 2004-07-14 Dick Porter <dick@ximian.com>
1641 * wait.c (test_and_own): When not waiting for all handles to
1642 become signalled, only own and return the lowest. All the
1643 documentation suggests that the old way was correct, but
1644 experimentation shows it actually works like this. Patch by
1645 Sébastien Robitaille
1646 (sebastien.robitaille@croesus.com), fixes bug 61511.
1648 2004-07-09 Ben Maurer <bmaurer@ximian.com>
1650 * threads.c: register roots for gc
1652 2004-07-08 Dick Porter <dick@ximian.com>
1654 * io.c (file_seek): If there is a high 32bit offset part, make
1655 sure the low part isn't sign-extended. Set error codes when
1656 returning failure. Fixes bug 61131.
1658 2004-07-06 Dick Porter <dick@ximian.com>
1660 * io.c (file_setfiletime): Check for underflow when converting to
1661 time_t values. Set error codes when returning failure. Fixes bug
1664 2004-07-05 Dick Porter <dick@ximian.com>
1666 * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable.
1668 * daemon.c (unref_handle): Only destroy a handle if all processes
1669 have released it, not just the current one. Fixes bug 60887.
1671 2004-06-30 Zoltan Varga <vargaz@freemail.hu>
1673 * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
1674 to prevent warnings.
1676 2004-06-24 Dick Porter <dick@ximian.com>
1678 * mutexes.c: Indicate when a named mutex was reused
1680 2004-06-24 Dick Porter <dick@ximian.com>
1682 * threads.c (SuspendThread):
1683 * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a
1684 while loop. See bug 58161.
1686 Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro <lupus@ximian.com>
1688 * io.c: don't use sharemode for on-disk file permissions: it's used
1689 for shared access to the open file.
1691 2004-06-22 Dick Porter <dick@ximian.com>
1693 * events.c (CreateEvent): When creating an auto-reset event that
1694 is initially owned, make sure the set count starts at 1.
1696 2004-06-18 Dick Porter <dick@ximian.com>
1699 * events.c: Auto-reset events need to release one thread for each
1700 time SetEvent() is called. Fixes bug 41292.
1704 * mutexes.c: Scan for mutexes that are still locked by a thread
1705 when it exits. Fixes the MS demo app linked by bug 41292.
1707 * wait.c (test_and_own): Make sure a handle is signalled before it
1710 2004-06-16 Dick Porter <dick@ximian.com>
1712 * timed-thread.c: Call the thread cleanup exit routine before taking
1713 the join mutex, because this could deadlock if another thread tries
1714 to join in the meantime. This fixes the hang-at-exit problem seen
1717 2004-06-03 Lluis Sanchez Gual <lluis@ximian.com>
1719 * threads.c: Implemented SleepEx.
1720 * threads.h: Fixed SleepEx signature.
1722 2004-06-03 Miguel de Icaza <miguel@ximian.com>
1724 * threads.c: When running under valgrind, do not allocate too much
1725 stack, as Valgrind default is 1 meg.
1727 2004-05-27 Dick Porter <dick@ximian.com>
1730 * io.c: Implemented LockFile() and UnlockFile()
1732 2004-05-21 Dick Porter <dick@ximian.com>
1734 * io.c (CreateFile): Check for existing share modes when opening
1738 * handles-private.h:
1739 * daemon-messages.h:
1740 * daemon.c: Maintain a hash of file share modes, keying on device
1741 and inode (to cope with symlinks.)
1743 2004-05-20 Lluis Sanchez Gual <lluis@ximian.com>
1745 * daemon-messages.c: Retry if the communication with the daemon is
1746 interrupted by a signal.
1747 * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped.
1748 Only return an error in this case if there is something in the apc queue
1749 (which means that it is an interruption requested by the "user").
1750 * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as
1751 true since the wait is small.
1752 * shared.c: Retry write calls when interrumped by a signal.
1753 * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which
1754 returns TRUE if there are pending asynchronous calls (APC) for the
1755 provided thread. Also added _wapi_thread_dispatch_apc_queue which calls
1756 the enqueued APCs. Defined a new struct ApcInfo that holds information
1757 about an enqueued APC.
1758 * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same
1759 as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue.
1760 These last two methods call the corresponding apc methods in
1761 thread-private using the provided thread handle.
1762 * threads.h: Added QueueUserAPC.
1763 * uglify.h: Added WapiApcProc (needed by QueueUserAPC).
1764 * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and
1765 WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support
1766 for APCs in those two methods and also in SleepEx.
1768 2004-05-17 Dick Porter <dick@ximian.com>
1770 * io.c (CopyFile): Speed up. Fixes bug 57859.
1772 2004-05-13 Dick Porter <dick@ximian.com>
1773 * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current
1774 thread doesn't own the mutex, rather than assert()ing.
1776 2004-05-11 Dick Porter <dick@ximian.com>
1778 * shared.c (_wapi_shm_attach): Cope when a previous daemon startup
1779 attempt failed, leaving shared files that look like a daemon is
1782 2004-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1785 (SetFileAttributes): don't the the exec bit if the corresponding read
1788 2004-05-10 Zoltan Varga <vargaz@freemail.hu>
1790 * io.c (FindFirstFile): Fix invalid free.
1792 2004-05-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1794 * io.c: translate from GFileError to errno codes and don't free
1795 variables right after calling mono_io_scandir, as we may overwrite
1798 2004-05-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1800 * io.c: g_dir_open return ENOENT for directories on which we don't have
1801 read/execute permission, while returning EPERM for anything below those.
1802 So, change ENOENT by EPERM if the directory exists.
1804 2004-05-07 Dick Porter <dick@ximian.com>
1806 * io.c (SetFileAttributes): Don't have failed chmod()s cause a
1807 "file not found" error. Fixes bug 54032.
1809 2004-05-07 Dick Porter <dick@ximian.com>
1811 * io.c (FindFirstFile): Comment out a windows-compatibility check
1812 that breaks when directories have metachars in their names.
1813 Workaround for bug 58116.
1815 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1817 * io.c: fixed for FindFirstFile for empty directories. Closes
1820 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1822 * processes.c: set the start time for the current process. Fixes bug
1825 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1827 * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
1828 * io.c: implemented scandir using glib functions.
1830 2004-05-04 Dick Porter <dick@ximian.com>
1832 * daemon.c (read_message): Return FALSE on error so the GSource
1833 callback itself can return FALSE. Cures the infinite loop poll()
1835 * shared.c: Fix some daemon startup race conditions.
1837 2004-04-29 Miguel de Icaza <miguel@ximian.com>
1839 * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k,
1840 use the stack, do not use dynamic memory.
1842 2004-04-29 Zoltan Varga <vargaz@freemail.hu>
1844 * io.c: Add scandir implementation for platforms which do not have
1847 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1849 * io.[ch]: implemented GetLogicalDriveStrings.
1851 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1854 * sockets.c: use the field name from configure when accessing sigval
1855 pointer field. Makes this work on the Mac.
1857 2004-04-28 Bernie Solomon <bernard@ugsolutions.com>
1859 * atomic.c: (InterlockedExchange) fix typo for
1862 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1865 * sockets.c: added check for sys/aio.h.
1867 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1869 * error.[ch]: added _wapi_get_win32_file_error...
1870 * io.c: ... which was _wapi_get_win32_error here.
1871 * sockets.c: rename the function calls here too.
1873 2004-04-28 Dick Porter <dick@ximian.com>
1875 * daemon-messages.c: Avoid a deadlock when a thread is killed while
1876 waiting for the daemon by using a recursive mutex. Helps bug 56699.
1878 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1880 * io.c: fixed leak in async_notifier().
1882 * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl
1885 * threads.c: removed old comment.
1887 2004-04-26 David Waite <mass@akuma.org>
1889 * daemon-messages.h:
1896 * wapi-private.h: remove comma from end of enumeration declarations
1897 * status.h: cast unsigned int types to int for enum assignment
1899 2004-04-26 David Waite <mass@akuma.org>
1902 * timefuncs.c: declare 64-bit constants as long long types (i.e.
1905 2004-04-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1907 * socket-wrappers.h: _wapi_socket == WSASocket now. Added
1908 WSA_FLAG_OVERLAPPED.
1910 * sockets.c: new unused parameters for _wapi_socket.
1912 2004-04-22 Miguel de Icaza <miguel@ximian.com>
1914 * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle
1915 the fact that MacOS X is a piece of junk (sem_init is *defined* in
1916 the libc, but they return `not implemented').
1918 2004-04-22 Dick Porter <dick@ximian.com>
1921 * handles-private.h: Reference the handle when it is locked, so
1922 that another thread can't blow it away while we're waiting for it
1923 to become signalled.
1934 * handles-private.h:
1937 * daemon-messages.c:
1938 * critical-sections.c:
1939 * atomic.c: Added pthreads cleanup handlers and error asserts
1942 * handles.c: Fixed the gcc "variable might be used uninitialised"
1943 warnings. They can't happen, but gcc doesn't know that
1944 g_assert()s don't return.
1946 Fixed the declaration of _wapi_handle_process_kill() so that it
1947 expects the correct type for the pid.
1949 * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that
1950 hasn't been used in ages and just made the code more complex.
1952 2004-04-17 Zoltan Varga <vargaz@freemail.hu>
1954 * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
1955 warnings. Fixes #57168.
1957 2004-04-16 Dick Porter <dick@ximian.com>
1959 * threads.c (Sleep): Using div(3) with a negative (when signed)
1960 numerator causes the quotient to be 0 and the remainder to be the
1961 numerator. This feeds a small negative value to nanosleep(3),
1962 which will return immediately and cause a busy wait. Fixes bug
1965 2004-04-15 Dick Porter <dick@ximian.com>
1968 * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3)
1969 and fnmatch(3) instead of glob(3). glob() can't cope with being
1970 given filenames containing metachars. This fixes bug 40557.
1972 2004-04-14 Bernie Solomon <bernard@ugsolutions.com>
1974 * security.c: #warning is a GCC-ism
1976 2004-04-13 Sebastien Pouliot <sebastien@ximian.com>
1978 * security.c: Removed GetUserName as glib g_get_user_name does a
1979 better (portability) job. Added ImpersonateLoggedOnUser and
1982 2004-04-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1984 * mono-mutex.h: move pthread_mutex_timedlock declaration to...
1985 * mono-mutex.c: ...here. It was causing a warning that prevented
1986 libgdiplus compilation.
1988 2004-04-04 Miguel de Icaza <miguel@ximian.com>
1990 * security.c (GetUserName): Make it work on MacOS X
1992 2004-04-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1994 * security.c: use getpwuid_r if available. This one is thread-safe.
1996 2004-04-02 Sebastien Pouliot <sebastien@ximian.com>
1998 * Makefile.am: Added security.c|h.
1999 * security.c: New file for security related functions. Added function
2000 GetUserName to fix #56144.
2001 * security.h: New. Header file for security.c
2002 * wapi.h: Added include for security.h
2004 2004-03-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2006 * daemon-messages.h: added kill structs.
2008 * daemon.c: implemented process_process_kill.
2009 * handles-private.h: define process_process_kill.
2010 * handles.c: implemented _wapi_handle_process_kill.
2011 * processes.[ch]: implemented TerminateProcess.
2013 2004-03-25 Bernie Solomon <bernard@ugsolutions.com>
2015 * daemon.c (rem_fd): On solaris you seem to get an
2016 error even after removing the input source so don't
2017 try and rem_fd it twice.
2019 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
2021 * daemon.c: in process_post_mortem, If the child terminated due to the
2022 receipt of a signal, the exit status must be based on WTERMSIG, since
2023 WEXITSTATUS returns 0 in this case.
2025 2004-03-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2027 * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.
2029 2004-03-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2031 * daemon.c: only call getdtablesize () once.
2032 * processes.c: wait 500 ms to check if execve failed and throw the same
2033 exception as MS on failure. Fixes bug #32809.
2035 2004-03-17 Bernie Solomon <bernard@ugsolutions.com>
2037 * io.c (async_notifier): use "union sigval" rather
2038 than sigval_t as Solaris doesn't have sigval_t
2039 (which isn't in IEEE 1003.1 either).
2041 2004-03-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2043 * io.c: added debug stuff and removed a few redundant lines in
2046 2004-03-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2048 * io-private.h: added new fields for file structure. Declare
2049 _wapi_io_add_callback.
2051 * io.c: added _wapi_get_win32_error, support aio_read/write in
2052 file_read/write. Implemented _wapi_io_add_callback, which is where
2055 * io.h: added new fields for WapiOverlapped and typedef for the
2058 * processes.c: fixed off-by-one bug when handling environment variables
2061 * threads.[ch]: implemented BindIoCompletionCallback.
2063 * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE.
2065 2004-03-14 Zoltan Varga <vargaz@freemail.hu>
2067 * socket-wrappers.h: Remove extra semicolon.
2069 2004-03-03 Dave Camp <dave@ximian.com>
2071 * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
2072 Use a new main context.
2074 2004-03-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2077 (GetFileAttributes): set the error depending on errno instead of
2078 setting ERROR_FILE_NOT_FOUND always. See bug #55160.
2080 2004-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2083 (CopyFile): free the buffer on error.
2085 (WSAIoctl): free the buffer on error.
2087 2004-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2089 * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT.
2091 * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW
2092 using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style.
2094 2004-01-27 Bernie Solomon <bernard@ugsolutions.com>
2096 * shared.c (_wapi_shm_file): add hostname
2097 to shared data file names to handle NFS mounted
2100 Mon Jan 26 16:15:03 CET 2004 Paolo Molaro <lupus@ximian.com>
2102 * sockets.h: remove obsolete soklen_t typedef.
2104 Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>
2106 * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket
2107 wrappers to its own non-installed header file.
2109 2004-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2112 (FindFirstFile): unlock the handle if FindNextFile fails.
2113 (FindNextFile): g_free a couple of pointers before retrying.
2116 (WaitForMultipleObjects): if only one handle provided, use
2117 WaitForSingleObject.
2119 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2121 * handles-private.h: (_wapi_handle_type) check
2122 for segment in range before using it
2124 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2126 * thread-private.h: _wapi_thread_ops is now const
2129 Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>
2131 * threads.c, timed-thread.c, timed-thread.h: use mach
2132 semaphores on Darwin (MacOSX) since the posix ones
2133 are mostly broken there (threads are not created suspended
2134 and they can start executing before they are fully initialized
2135 like in tests/thread-static.cs).
2137 Mon Dec 22 17:18:45 CET 2003 Paolo Molaro <lupus@ximian.com>
2139 * atomic.h: ppc fixes.
2141 2003-12-19 Bernie Solomon <bernard@ugsolutions.com>
2143 * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
2146 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2148 * shared.c: (_wapi_shm_open) make scratch file
2149 not have to immediately regrow to avoid remaps
2150 (HPUX can't cope with these).
2151 (_wapi_shm_attach) use actual size of file
2152 to set scratch data_len for the creating process.
2154 * handles.c: (_wapi_handle_new_internal) make
2155 sure mutex & cond var are initialized even for
2156 non process shared ones.
2157 (_wapi_handle_unref) always call destroy
2158 routines on mutex & cond var
2160 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2162 * daemon.c: change channel data structure so
2163 input sources are removed from glib event loop
2164 properly. xsp works better on Solaris and
2167 2003-12-12 Bernie Solomon <bernard@ugsolutions.com>
2169 * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
2170 definition with file & line number for non-GCC
2173 2003-12-08 Bernie Solomon <bernard@ugsolutions.com>
2175 * Makefile.am: make sure hppa_atomic.s is in distribution
2177 2003-12-01 Dick Porter <dick@ximian.com>
2180 * mutexes.c (CreateMutex):
2181 * mutex-private.h (struct _WapiHandle_mutex):
2182 * handles.c: Look up certain handle types by name, in a shared
2183 namespace. Currently only mutex handles have this implemented.
2186 * semaphores.c (CreateSemaphore):
2187 * events.c (CreateEvent): Fix signature
2189 2003-11-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2191 * io.c: don't call g_free before testing errno as it may modify it.
2192 If the path exists, return an error if it's not a directory. Fixes
2195 2003-11-20 Dick Porter <dick@ximian.com>
2197 * io.c: Missed a little-endian UTF16 conversion. Patch from
2198 Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.
2200 2003-10-29 Dick Porter <dick@ximian.com>
2202 * io.c (MoveFile): If the move crosses filesystems, try and fall
2203 back to copy and delete. Patch from Jörg Rosenkranz
2204 (JoergR@voelcker.com), fixes bug 50298.
2206 2003-10-28 Dick Porter <dick@ximian.com>
2208 * io.c: Use the new encoding conversion to cope with non-utf8
2209 locales in filenames.
2211 * processes.c: Ditto for process arguments.
2213 Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro <lupus@ximian.com>
2215 * atomic.h: some ppc inline asm fixes (incorrect use of labels,
2216 incorrect register constraints, incorrect clobber lists).
2218 2003-10-13 Bernie Solomon <bernard@ugsolutions.com>
2220 * Makefile.am hppa_atomic.s: add HP 64bit
2221 implementation of atomic ops
2223 2003-10-13 Zoltan Varga <vargaz@freemail.hu>
2225 * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
2226 a conditional for platforms that don't have it.
2228 2003-10-09 Bernie Solomon <bernard@ugsolutions.com>
2230 * threads.c: (CreateThread) use stacksize argument
2231 if non-zero - change default for 64 bits to 4Mb
2233 2003-09-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2235 * sockets.c: set last error when socket creation fails. This shed some
2236 light on bug #49015.
2238 2003-09-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2240 * processes.c: fixed bug #48973: we only change \ by / for the argument
2241 to be used as command.
2242 When getting the program name from the args, don't let the space between
2245 2003-09-24 Bernie Solomon <bernard@ugsolutions.com>
2247 * atomic.h atomic.c: fix sparc so lock is
2248 global, increment does so and it compiles under Sun compiler.
2250 2003-09-22 Bernie Solomon <bernard@ugsolutions.com>
2252 * handles.c: include <string.h> directly as may
2253 not be nested in <sys/un.h> like Linux
2255 2003-09-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2258 (DeleteFile): call SetLastError on failure. Fix by
2259 richard.torkar@htu.se (Richard Torkar). Closes bug #48222.
2261 2003-09-15 Lluis Sanchez Gual <lluis@ximian.com>
2263 * daemon.c: In compare_process(), discard handles already signalled.
2265 2003-09-02 Dick Porter <dick@ximian.com>
2267 * io.c: Work around glib brain-dead assumptions about utf8-encoded
2268 filenames. Fixes bug 30781.
2270 2003-08-28 Dick Porter <dick@ximian.com>
2272 * critical-sections.c: Patch from Bernie Solomon
2273 <bernard@ugsolutions.com> to emit a warning if locking a critical
2276 2003-07-23 Dick Porter <dick@ximian.com>
2279 * daemon.c (maybe_exit): Avoid the race condition when the daemon is
2280 closing but another client comes along when the shared data is still
2281 visible. Should fix bugs 33671 and 35213.
2283 2003-07-23 Dick Porter <dick@ximian.com>
2285 * handles.c: Initialise handle mutex and cond. Fix by
2286 Bernie Solomon <bernard@ugsolutions.com>
2288 2003-07-15 Dick Porter <dick@ximian.com>
2290 * timed-thread.c (timed_thread_start_routine): Fix virtual memory
2291 leak when threads quit. Fixes bug 44067.
2293 Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro <lupus@ximian.com>
2295 * io.c: never add write permission for group or others in
2296 SetFileAttributes ().
2298 2003-06-17 Dick Porter <dick@ximian.com>
2300 * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
2301 ignore the unsupported ones ("fixes" bug 44977).
2303 2003-06-17 Lluis Sanchez Gual <lluis@ximian.com>
2305 * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for
2306 high ms values (there was an overflow).
2308 2003-06-17 Zoltan Varga <vargaz@freemail.hu>
2310 * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.
2312 2003-06-11 Dick Porter <dick@ximian.com>
2314 * shared.c: Fix shared directory creation. Patch from
2315 Pablo Baena <pbaena@uol.com.ar>
2317 2003-06-10 Dick Porter <dick@ximian.com>
2319 * atomic.c: Delete the useless compile warning
2321 2003-06-09 Dick Porter <dick@ximian.com>
2323 * daemon.c: Lookup env as a string array. Fixes bug 44289. Also
2324 make setting the process handle value in the environment actually
2327 * processes.c: Pretty up the process name, if it happens to be
2328 "mono" such as when another mono process forks "mono foo.exe"
2330 2003-06-05 Dick Porter <dick@ximian.com>
2332 * processes.c (process_set_current): Don't do an expensive handle
2333 search at application startup, check the environment to see if the
2334 process handle has already been created.
2336 * io.c: Don't do an expensive handle search when creating stdin,
2337 stdout and stderr handles, just create them all the first time one
2344 * handles-private.h:
2345 * daemon-messages.h:
2347 * daemon.c: Support for "unlimited" number of handles and scratch
2350 Speed up application startup by passing process handle in the
2351 environment, rather than let the app scan all handles (which gets
2352 really slow when there are more than a few thousand to check.)
2354 Initialise some structs passed to syscalls, noticed by valgrind.
2357 2003-05-20 Dick Porter <dick@ximian.com>
2359 * io.c (FindFirstFile): Include . files in the glob. Fixes bug
2362 2003-05-19 Dick Porter <dick@ximian.com>
2364 * threads.c: Set the new thread's stack size to 2M. Fix needed
2365 for BSD, reported by Martin Dvorak <md@9ll.cz>
2367 2003-05-16 Dick Porter <dick@ximian.com>
2370 * io.c: Implement GetTempPath()
2372 2003-05-16 Dick Porter <dick@ximian.com>
2374 * processes.c (CreateProcess): Set some error codes
2376 2003-05-12 Dick Porter <dick@ximian.com>
2378 * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
2379 Patch from Martin Dvorak <mdvorak@ninell.cz>.
2381 2003-05-10 Dick Porter <dick@ximian.com>
2383 * io.c (CopyFile): Copy file mode as well as file data. Based on
2384 suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
2387 2003-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2389 * handles.c: don't call GC_gcollect when creating new handles.
2391 2003-05-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2393 * handles.c: added some debugging code. Call GC_gcollect
2394 before creating a new handle. It makes Lupus' test run smoother and
2395 faster (from 62 to 83 request per second). Notice that calling
2396 GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does
2397 not improve nor degrade the performance, so i don't do it.
2399 2003-05-02 Dick Porter <dick@ximian.com>
2401 * sockets.c: Rearrange closesocket() and socket_close_private(),
2402 and remember to unref the handle, so we don't leak socket handles.
2403 Fix from Pelle Johnsen <pelle.johnsen@mail.dk>
2405 2003-04-11 Dick Porter <dick@ximian.com>
2407 * atomic.h: ARM atomic operations by Malte Hildingson
2408 <tds00mahi@tellus.thn.htu.se>
2410 Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>
2412 * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.
2414 2003-04-03 Martin Baulig <martin@ximian.com>
2416 The following change is conditional to `WITH_INCLUDED_LIBGC'
2417 which is not yet enabled by default.
2419 * threads.c (SuspendThread, ResumeThread): Fully implemented this.
2420 (gc_init): New static function; install a signal handler for
2421 SIGPWR which is used to suspend threads. [FIXME: it SIGPWR
2422 doesn't exist on all Unix systems, we need to find another
2424 (mono_wapi_push_thread_stack): New public function. Tells the
2425 garbage collector about the current stack pointer of a suspended
2428 2003-04-03 Martin Baulig <martin@ximian.com>
2430 * timed-thread.h (TimedThread): Added `suspended_sem',
2431 `suspend_count' and `stack_ptr'.
2433 2003-03-28 Dick Porter <dick@ximian.com>
2435 * atomic.h: PPC support gratiously donated to the public domain
2436 by John Duncan <jddst19@mac.com>
2438 2003-03-20 Dick Porter <dick@ximian.com>
2440 * sockets.c (_wapi_connect): If connect() fails with EACCES, try
2441 setting SO_BROADCAST and connecting again. Fixes bug 39178.
2443 2003-03-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2445 * processes.c: included Jerome Laban's patch and call SetLastError when
2446 the executable is not found.
2448 2003-03-03 Dick Porter <dick@ximian.com>
2450 * io.c (CreateFile): Try opening directories readonly, so that
2451 timestamps can be adjusted. Patch by Elan Feingold
2452 <efeingold@mn.rr.com>.
2454 2003-02-25 Dick Porter <dick@ximian.com>
2456 * shared.c (_wapi_shm_attach): Return a failure code on system
2457 call errors, rather than exiting.
2459 2003-02-21 Dick Porter <dick@ximian.com>
2461 * processes.c (GetCurrentProcessId): Use the current process
2462 handle to return the process ID, as getpid() is unreliable
2463 (linuxthreads gives each thread a different pid). Fixes bug
2466 2003-02-21 Dick Porter <dick@ximian.com>
2468 * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug
2471 2003-02-11 Dick Porter <dick@ximian.com>
2474 * timefuncs.c: Added GetTickCount()
2476 2003-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2478 * error.c: added WSA_EHOSTUNREACH mapping.
2480 2003-01-26 Miguel de Icaza <miguel@ximian.com>
2482 * io.c (SetFileAttributes): This routine is not currently
2483 implemented for the general case, but I added a special case to
2484 set the executable bit on Linux.
2486 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
2488 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
2490 2003-01-08 Dick Porter <dick@ximian.com>
2492 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
2494 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
2496 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2497 Check for an implementation which says it supports
2498 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
2499 defines the symbol. Defined but with a value of -1 still
2500 means that it is unsupported.
2502 2002-12-08 Martin Baulig <martin@ximian.com>
2504 * handles.c (_wapi_handle_new): Create new non-shared handles with
2505 an initial refcount of 1, not 0.
2507 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
2509 * threads.c (TlsGetValue): removed unnecessary mutex
2511 2002-11-20 Dick Porter <dick@ximian.com>
2513 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
2514 need to store their data structure too.
2516 * threads.c: Make sure the threading data is initialised wherever
2519 2002-11-15 Dick Porter <dick@ximian.com>
2521 * timed-thread.c: Removed unneeded parameters in
2522 _wapi_timed_thread_attach().
2524 * threads.c: Renamed AttachThread() to make it not look like
2525 external API. Removed unneeded parameters.
2527 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2529 * error.[ch]: added errno_to_WSA (). It displays a warning and return
2530 WSASYSCALLFAILURE if there is no error mapping for the given errno,
2532 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
2534 2002-10-31 Dick Porter <dick@ximian.com>
2537 * io.c: Define and use INVALID_FILE_ATTRIBUTES
2539 2002-10-07 Dick Porter <dick@ximian.com>
2542 * daemon.c: Use a more accurate time source for process start and
2545 2002-10-03 Dick Porter <dick@ximian.com>
2549 * threads.c: Fixes for freebsd. Make sure that mutex and condition
2550 creation and deletion happen in the process that owns them, when
2551 POSIX shared thread objects aren't supported. This breaks on
2552 freebsd, as pthread_t is a pointer to data.
2554 2002-10-02 Dick Porter <dick@ximian.com>
2556 * shared.c: Use mmap() instead of sysv shm for the shared data.
2558 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
2562 * daemon.c: mmap()ed regions survive fork, so just pass the
2563 pointer to _wapi_daemon_main instead of mapping it again.
2565 2002-10-01 Dick Porter <dick@ximian.com>
2567 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
2568 Unfortunately libgc uses the same thread suspend technique that I
2569 want to, and the two don't mix: libgc will deadlock when it tries
2570 to stop the world if a thread has already been suspended by
2571 someone else. Just do the simple suspended create rather than the
2572 general purpose thread suspension for now.
2574 * threads.c: Pass create flags to the timed_thread create call, to
2575 implement suspended thread creation. ResumeThread() partially
2576 implemented, to cope with the case where a newly created but
2577 suspended thread is launched.
2579 2002-09-30 Dick Porter <dick@ximian.com>
2581 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
2584 2002-09-27 Dick Porter <dick@ximian.com>
2586 * semaphores.c: Only include semaphore.h if it's present. Patch
2587 for BSD from jmmv@hispabsd.org (Julio Merino).
2589 2002-09-27 Dick Porter <dick@ximian.com>
2591 * processes.c: Pass environment and working directory to the
2592 daemon when forking. Don't let argv[0] be duplicated when looking
2593 for the program name. Implement EnumProcessModules (simple
2594 version for now, lsof-style later if needed), GetModuleBaseName,
2595 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
2596 aren't available on Linux).
2598 * process-private.h: Store the process name, and the working set
2602 * handles-private.h: New functions to store and retrieve an array
2603 of strings in the scratch space
2605 * daemon.c: Don't miss deleting some handles when a client exits
2606 (we used to rely on the client doing the final cleanup, but
2607 obviously if the client is no longer there the daemon has to do
2610 Process forking now sets the environment and the working
2613 * io.c: Don't confuse fd 0 with an unassigned handle struct
2615 * atomic.h: Add a google cache alternative to the msdn URL
2617 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2620 (_wapi_recvfrom): added ECONNRESET to the switch.
2622 2002-09-24 Mark Crichton <crichton@gimp.org>
2624 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
2627 2002-09-19 Mark Crichton <crichton@gimp.org>
2629 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
2630 dont have Linux's abstract filesystem for sockets.
2632 2002-09-19 Mark Crichton <crichton@gimp.org>
2634 * atomic.h: Added SPARC atomic asm code.
2635 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2636 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
2637 Solaris 9, however, the code paths don't seem to work. More testing
2638 on the shared case is *really* needed.
2640 2002-09-03 Dick Porter <dick@ximian.com>
2643 * threads.c: Removed PosixKillThread(), because it's not in the
2646 2002-08-20 Dick Porter <dick@ximian.com>
2648 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
2649 multiples of 4 bytes, to keep header structures aligned. Needed
2650 for sparc, at least. (Patch from crichton@gimp.org)
2652 * handles.c: Removed 'disable_shm' variable (we've defaulted to
2653 building with shm enabled for months now)
2655 2002-08-19 Dick Porter <dick@ximian.com>
2657 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
2658 for legacy NeXT-based systems.
2660 2002-08-12 Dick Porter <dick@ximian.com>
2662 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
2663 from Joseph Wenninger <kde@jowenn.at>)
2665 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
2667 * threads.c: use fast spinlocks by default
2669 2002-08-02 Dick Porter <dick@ximian.com>
2671 * io.c (GetStdHandle): Add a handle reference when returning a
2672 duplicate console handle. This fixes the unref_handle errors in
2675 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
2677 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
2680 2002-08-01 Dick Porter <dick@ximian.com>
2682 * threads.c: Use atomic spinlocks in TLS functions
2685 * Makefile.am: Added mono-spinlock.h
2687 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
2689 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
2690 these are needed for sendmsg() and also for struct msghdr (at
2691 least on Solaris). Solaris still won't build because struct msghdr
2692 doesn't have msg_flags, msg_control, or msg_controllen members.
2693 (CMSG_SPACE): Define for systems that don't have it.
2696 2002-07-20 Dick Porter <dick@ximian.com>
2702 * handles.c: Implemented pipe handles
2705 * daemon.c: Fixed bug in handle closing.
2708 * daemon.c: Forked processes now close all open file descriptors.
2710 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
2712 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
2715 2002-07-19 Martin Baulig <martin@gnome.org>
2717 * threads.c (ExitThread): Call exit() if no threads has been
2720 2002-07-17 Dick Porter <dick@ximian.com>
2722 * daemon-messages.c: Freebsd fixes from Andreas Kohn
2723 <andreas.kohn@gmx.net>
2725 2002-07-15 Dick Porter <dick@ximian.com>
2727 * io.c: Removed bogus console_flush() method, that was just cut
2728 and pasted from file_flush when I separated the two handle types.
2730 2002-07-12 Dick Porter <dick@ximian.com>
2732 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
2733 flags. Fixes bug 27633.
2735 2002-07-12 Dick Porter <dick@ximian.com>
2739 * daemon.c: Use size of sockaddr_un.sun_path from config.h
2741 2002-07-12 Dick Porter <dick@ximian.com>
2743 * processes.c (CreateProcess): Send stdin, stdout and stderr
2744 handles if the startup info doesnt specify new ones
2746 * io.c (GetStdHandle): Return the same handle when the same
2747 standard handle is requested
2749 * handles.c: Pass file descriptors when forking
2751 * daemon.c: Use supplied file descriptors when forking a new
2754 * daemon-messages.h:
2755 * daemon-messages.c: Pass stdin, stdout and stderr file
2756 descriptors to the daemon (used when forking)
2758 2002-07-11 Miguel de Icaza <miguel@ximian.com>
2760 * daemon.c (_wapi_daemon_main): Use sizeof
2761 (main_socket_address.sun_path) instead of hardcoded 108 value.
2763 * handles.c (shared_init): Use sizeof
2764 (shared_socket_address.sun_path) instead of hardcoded 108 value.
2766 2002-07-10 Dennis Haney <davh@davh.dk>
2770 * daemon.c: Lots of documentation, some added error checking, and
2771 code readability improvements.
2773 * daemon-messages.h: Add the Error request type to improve error
2776 * daemon-messages.c: Do a bit more error checking on send() and
2777 recv(), and log errors with a higher severity level.
2779 2002-07-04 Dick Porter <dick@ximian.com>
2781 * daemon.c (process_process_fork): Fix argument handling, due to
2782 buggy understanding of g_strsplit() behaviour.
2784 2002-07-03 Dick Porter <dick@ximian.com>
2787 * threads.c: Implement OpenThread(). Define access-control values
2793 * Makefile.am: Added access.h, to hold shared access-control
2796 2002-07-02 Dick Porter <dick@ximian.com>
2798 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
2800 2002-07-02 Dick Porter <dick@ximian.com>
2802 * handles.c (shared_init): Make a second attempt to contact the
2803 daemon if the shared memory attach succeeds, but the connect()
2804 fails. (This copes with the daemon crashing without cleaning up
2810 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
2811 the daemon, it's now built into the library.
2813 2002-06-25 Dick Porter <dick@ximian.com>
2816 * handles-private.h:
2817 * daemon-messages.h:
2818 * daemon.c: Process forking and handle data management
2821 * process-private.h:
2822 * processes.c: Process forking and other support functions
2824 2002-06-25 Dick Porter <dick@ximian.com>
2826 * versioninfo.h: PE resource decoding
2828 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
2829 to be told the string length
2831 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
2832 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
2835 2002-06-12 Dick Porter <dick@ximian.com>
2838 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
2839 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
2840 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
2842 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
2844 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
2845 when writing to a closed socket.
2847 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
2849 * mono-mutex.c (mono_once): New convenience function for my
2854 * critical-sections.c:
2862 * atomic.c: Use mono_once() rather than pthread_once().
2864 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
2866 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
2867 if multiple threads all try to call _wapi_handle_new() before the
2868 shared data has been initialized, it is possible that we could get
2869 into a condition where shared_init() is being executed and later
2870 threads will pass by pthread_once() due to the fact that it has
2871 already been called and so therefor will attempt to use the shared
2872 data before it has been completely initialized. If we instead use
2873 a standard mutex locking mechanism around shared_init(), we can
2874 avoid the situation entirely. By wrapping the mutex locking in a
2875 check to see if we've already initialized the data, we can even
2876 avoid wasting resources by having to lock/unlock the mutex in any
2877 later calls (the only time we'd have to worry about
2878 locking/unlocking is the initial race to call shared_init() at
2881 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
2883 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
2885 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
2887 * daemon.c, handles.c: rename "sun" local var since it's apparently
2888 a #define on Solaris.
2890 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
2892 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
2895 2002-05-15 Dick Porter <dick@ximian.com>
2897 * wait.c: Fix a deadlock in WaitForMultipleObjects
2899 2002-05-14 Dick Porter <dick@ximian.com>
2901 * io.c: Fix a cut&paste error, found by
2902 Jaroslaw Kowalski <jarek@atm.com.pl>
2904 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
2908 2002-05-09 Dick Porter <dick@ximian.com>
2914 * handles-private.h:
2916 * Makefile.am: Remove now-unused file wait-private.h
2918 2002-05-08 Dick Porter <dick@ximian.com>
2920 * shared.c: Better error messages, and report when daemon
2921 connection fails rather than blocking forever. Do some more
2922 shared memory sanity checking.
2924 * handles.c: Better error messages when connecting to shared
2925 memory and the handle daemon. Fall back to non-shared handles if
2926 an error occurs. Set the default back to 'shared handles'. Fix a
2927 crashing bug in scratch space allocation that mangled the block
2930 2002-05-07 Miguel de Icaza <miguel@ximian.com>
2932 * handles.c (shared_init): Disable SHM for now, people have too
2933 many problems with this, and the diagnostics are not helping.
2935 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
2937 * io.c: CreateFile sets win32 last error.
2939 2002-05-05 Dick Porter <dick@ximian.com>
2942 * handles-private.h:
2948 * process-private.h:
2950 * semaphore-private.h:
2954 * event-private.h: Simplify the WapiHandleOps struct: take out all
2955 the file-specific entries, leaving just the items that operate on
2956 handles themselves. Split the close operation into shared and
2957 private parts: shared close is called by the daemon.
2959 * handles.c: As above, but also pass handle allocation, ref and
2960 unref operations to the daemon. Populate the handle_ops array at
2961 compile time, because the daemon needs to call ops on handles too.
2962 Don't bother to track open handle counts any more, the daemon does
2966 * thread-private.h: As above, but also make the thread data
2969 * shared.c: Fork a handle daemon if the calling process created
2970 the shared memory segment.
2973 * daemon-messages.c:
2974 * daemon-messages.h:
2975 * Makefile.am: Build a daemon to manage handle allocation and
2976 destruction without needing to lock the shared memory
2978 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
2980 * atomic.c: Changed to use a normal mutex rather than a spinlock
2981 since a lot of platforms seem to not have them :\
2983 2002-04-30 Dick Porter <dick@ximian.com>
2985 * Completely rewrote the handle waiting code: removed the helper
2986 thread and its attendant complexity. All handle waiting is now
2987 abstracted into the WaitForSingleObject() and
2988 WaitForMultipleObjects() functions.
2990 * Implemented inter-process sharing of handles using sysv shared
2991 memory. This makes handles even more opaque, with a handle now
2992 just an index into an array.
2994 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
2996 * io.c: unitialized pointer in GetCurrentDirectory.
2998 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
3000 * threads.c: destroy the mutex at thread destruction
3001 (if/when thread destruction code will be actually called).
3002 When protecting a tls data pointer from the gc, use also the
3003 thread id in the key.
3005 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
3007 * timed-thread.c: avoid race condition when setting the thread to
3010 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3012 * jit.h: to more #include lines to avoid breaking compilation
3013 under windows when upgrading mingw and w32api to version
3016 2002-04-16 Dick Porter <dick@ximian.com>
3018 * atomic.h: Explanatory comment about lack of 80386 support
3020 2002-04-15 Dick Porter <dick@ximian.com>
3022 * atomic.h: use xaddl for InterlockedIncrement() and
3023 InterlockedDecrement(). Use cmpxchgl in a loop for
3024 InterlockedExchange() and InterlockedExchangePointer().
3026 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
3028 * unicode.c: fix unicode_len() to not access uninitialized memory
3029 (and updated to conform to mono code style).
3031 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
3033 * io.c: EEXISTS is ignored for directory creation.
3034 * mono-mutex.h: remove silly "pragma }" that emacs users insert
3035 because they use a broken editor:-)
3037 2002-03-28 Dick Porter <dick@ximian.com>
3043 * handles.c: Warning cleanups
3045 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
3047 * unicode.h, unicode.c: changed to gunichar2
3048 * io.h, io.c: changed strings to gunichar2*, added
3049 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
3050 some fixes to FindFirstFile() and friends.
3052 2002-03-26 Dick Porter <dick@ximian.com>
3054 * types.h: Implement the large integer struct
3057 * timefuncs.c: Dummy functions that don't yet implement
3058 QueryPerformanceCounter() and QueryPerformanceFrequency()
3061 * threads.c: Implement SleepEx()
3064 * system.c: Beginnings of GetSystemInfo()
3066 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
3070 * context.c: Dummy function that doesnt yet implement
3074 * atomic.c: Interlocked functions
3076 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
3078 * threads.c: use a gc-safe hash table to store tls pointers.
3080 2002-03-22 Dick Porter <dick@ximian.com>
3082 * threads.c: Fix a race condition where a thread can start and
3083 exit before the handle has been properly initialised (no reason
3084 why the handle couldn't be initialised beforehand, so do so)
3086 Fix a ms to ns conversion magnitude thinko.
3088 2002-03-21 Dick Porter <dick@ximian.com>
3090 * semaphores.c: Fix a problem when waiting for one or more
3091 semaphores, and another semaphore is Released (all waiting
3092 semaphores assumed they were signalled)
3094 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
3096 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
3097 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
3099 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
3101 * threads.c (Sleep): bug fix: 1ms == 1000000ns
3103 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
3105 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
3106 threads.c, io.c: added flush method to handles.
3108 * io.c: FlushFileBuffers() and FindFirstFile() functions.
3110 Thu Mar 7 17:21:52 CET 2002 Paolo Molaro <lupus@ximian.com>
3112 * threads.c, timed-thread.c, wait.c: Boehm-GC anable.
3114 2002-02-20 Dick Porter <dick@ximian.com>
3116 * io-layer.h: Always build without cygwin support on windows
3118 Mon Feb 18 15:50:59 CET 2002 Paolo Molaro <lupus@ximian.com>
3120 * sockets.c: #undef DEBUG.
3122 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
3124 * io-layer.h: conditionally include sys/filio.h and sys/sockio.h
3125 for FIONBIO, FIONREAD, and SIOCATMARK.
3127 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
3129 * sockets.c: conditionally include sys/filio.h and sys/sockio.h
3130 for FIONBIO, FIONREAD, and SIOCATMARK.
3132 2002-02-13 Dick Porter <dick@ximian.com>
3134 * sockets.c: Implement shutdown and select
3136 2002-02-13 Jeffrey Stedfast <fejj@ximian.com>
3138 * mono-mutex.[c,h]: New source files that thinly wrap all pthread
3139 functions that take pthread_mutex_t and/or pthread_mutexattr_t
3140 arguments for the sake of portability. Implements recursive
3141 mutexes and pthread_mutex_timedlock.
3143 * critical-sections.c:
3150 * wait.c: Use the mono-mutex wrapper portability functions/macros.
3152 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
3154 2002-01-23 Dick Porter <dick@ximian.com>
3156 * sockets.c: Networking support, mostly wrapping BSD socket APIs
3157 with handle code, and translating errno into w32 error codes.
3159 * macros.h: Some w32 macros used with the socket support
3161 * error.c: Implemented GetLastError() and SetLastError()
3163 * Makefile.am: Added sockets, with kludge to override some symbols
3165 2001-12-17 Dietmar Maurer <dietmar@ximian.com>
3167 * unicode.c (_wapi_unicode_to_utf8): byteswap UTF16 strings before
3168 passing them to iconv
3169 (_wapi_unicode_to_utf8): only swap bytes on LE systems, remove bug
3170 from previous commit.
3172 2001-12-11 Dick Porter <dick@ximian.com>
3174 * io.c: Implement DeleteFile(), GetFileTime(), SetFileTime() and
3175 FileTimeToSystemTime().
3177 * unicode.c (unicode_len): Nasty way of finding length of unicode
3178 string with embedded NULLs (counts until two NULLs together).
