37 breaks async connects. (Bug 377589 test case broken by the
38 previous fix to bug 356552)
40 2008-05-25 Zoltan Varga <vargaz@gmail.com>
42 * thread-private.h (struct _WapiHandle_thread): Remove 'owner_pid' field. Reorder
43 fields so this struct (which is the biggest of the handle structs) takes less
46 * threads.c (QueueUserAPC): Make this function signal safe by adding some
47 restrictions on its usage.
49 2008-05-14 Zoltan Varga <vargaz@gmail.com>

62 creation of wapi handle slots.
64 2008-04-24 Zoltan Varga <vargaz@gmail.com>
66 * handles.c (shared_init): Align _wapi_fd_reserve to a multiple of

77 compensate for the decrease in _WAPI_HANDLE_INITIAL_COUNT.
79 * threads.c: Use #ifdef instead of #if for checking for valgrind/memcheck.h.
81 2008-04-22 Dick Porter <dick@ximian.com>
83 * wapi_glob.c (globextend): Comment out the code using ARG_MAX, as
84 that is broken on the latest opensuse.
86 2008-04-21 Dick Porter <dick@ximian.com>
88 * io.c (DeleteFile): Disable for now the bug fix for 323389, it's
89 breaking too much other stuff.
91 2008-04-20 Geoff Norton <gnorton@novell.com>
93 * processes.c: Fix the _NSGetEnviron define to prevent an impropoer
96 2008-04-18 Miguel de Icaza <miguel@novell.com>

110 2008-04-11 Geoff Norton <gnorton@novell.com>
112 * processes.c: The global extern environ doesn't exist on Mac. We
113 need to call NSGetEnviron instead.
115 2008-04-08 Dick Porter <dick@ximian.com>
117 * processes.c (CreateProcess): Improve the managed binary support,
118 so it works when the executable is passed in as the appname.
121 2008-04-04 Dick Porter <dick@ximian.com>
123 * io.c (MoveFile): Check file shares before moving a file. Fixes
126 2008-04-04 Dick Porter <dick@ximian.com>

142 2008-04-03 Dick Porter <dick@ximian.com>
144 * timefuncs.c (GetTickCount): Use mono_msec_ticks(), see bug
147 2008-04-01 Dick Porter <dick@ximian.com>
149 * versioninfo.c (get_string_block): Refine the fix for bug 354856
150 (r93661) so that it also fixes the new part of bug 374600.
152 2008-03-28 Dick Porter <dick@ximian.com>
154 * processes.c (GetExitCodeProcess): Check if a process has exited
155 and recorded it's exit code, before seeing if the process is
156 signalled. Fixes bug 325463.
158 2008-03-27 Dick Porter <dick@ximian.com>
160 * processes.c (match_procname_to_modulename): Check the whole
161 process name first, in case it is recorded as an absolute path.
164 2008-03-27 Dick Porter <dick@ximian.com>
166 * processes.c (ShellExecuteEx): Grotty kludge to work around
167 unpleasant feature in g_shell_parse_argv() where it treats '#'
168 embedded in a filename as a comment marker, and throws away the
169 rest of the line. When we're directly opening URLs quote the
170 filename, to avoid this. Fixes bug 371567.
172 2008-03-25 Dick Porter <dick@ximian.com>
174 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment file layout
177 * threads.c: Make thread handles private to the process that owns
180 2008-03-22 Kornél Pál <kornelpal@gmail.com>

183 supporting it. This fixes MSVC build with new Windows SDKs that declare
184 GetProcessId unconditionally.
186 2008-03-20 Kornél Pál <kornelpal@gmail.com>
188 * io-layer.h: Removed Windows version macros.
190 Thu Mar 13 16:24:53 CET 2008 Paolo Molaro <lupus@ximian.com>

198 2008-01-31 Bill Holmes <billholmes54@gmail.com>
199 * processes.c (match_procname_to_modulename) : Added to check if the last
200 part of module name is equal to the process name.
202 * processes.c (EnumProcessModules) : Changed the first entry in the returned
203 modules array (the process module) to be populated from the entry found
206 * processes.c (get_module_name & GetModuleInformation) : In the case where
207 the module passed in is NULL, search the /proc/<PID>/maps for a name that
208 matches the process name to populate the return information.
212 2008-01-29 Zoltan Varga <vargaz@gmail.com>
214 * security.c (RevertToSelf): Make this return TRUE if impersonating is not
217 * sockets.c (_wapi_connect): Add a workaround to a solaris x86 problem where

223 * versioninfo.c (get_string_block): When stepping over the
224 StringTable block, do not read an extra block at the end. Fixes

227 2008-01-19 Dick Porter <dick@ximian.com>
229 * versioninfo.c (get_stringtable_block): Cope when the StringTable
230 block is first in the resources data, and we just need to step
231 over it. Fixes bug 354856.
233 2008-01-16 Dick Porter <dick@ximian.com>
235 * threads.c (_wapi_thread_set_termination_details): Move the
236 thread abandonment to outside the shared handle lock. Fixes bug
239 2008-01-16 Dick Porter <dick@ximian.com>
241 * versioninfo.c (VerQueryValue): Include trailing null in returned
242 string length, for MS compatibility.
244 2008-01-09 Dick Porter <dick@ximian.com>

247 work on big-endian systems.
248 (scan_resource_dir): Copy the resource directory entry and
249 byteswap if necessary so it works big-endian. This fixes bug
250 345972 for real this time.
251 (VerQueryValue): String values set the length to the number of
252 unicode chars, but the data length reported was already correct so
253 don't halve it again. Fixes the previous fix for bug 345972.
254 (GetFileVersionInfo): On big-endian systems, scan the resource
255 data and turn all unicode strings into UTF-16BE. FileVersionInfo
256 now works big-endian.
258 2008-01-04 Dick Porter <dick@ximian.com>
260 * versioninfo.c (VerQueryValue): Returned buffer length counts
261 chars not bytes for string data. Fixes bug 345972 again.
262 (get_enclosing_section_header): Make sure values read are treated
263 as LE. Fixes crash on ppc reported in bug 345972.
265 2007-12-17 Mark Probst <mark.probst@gmail.com>
267 * threads.c: Guard against a race condition involving
268 thread_hash_key that can occur during shutdown.
270 2007-12-08 Zoltan Varga <vargaz@gmail.com>

302 2007-11-15 Dick Porter <dick@ximian.com>
304 * processes.c (load_modules): Don't bother if we don't have
305 g_strsplit_set() and g_strv_length(). Allows building against old
307 (EnumProcessModules): Don't miss the first module returned by
310 2007-11-15 Dick Porter <dick@ximian.com>
312 * processes.c: Implement process module support by reading from
313 /proc if it's available.
316 * versioninfo.c: New functions to implement PE file version info
319 2007-11-08 Dick Porter <dick@ximian.com>
321 * critical-sections.h (EnterCriticalSection): Disable the critical
322 section asserts for the release branch
324 2007-11-05 Kornél Pál <kornelpal@gmail.com>
326 * io-layer.h: Added includes for run-time GetProcessId API detection for
329 2007-10-26 Dick Porter <dick@ximian.com>
331 * shared.c (_wapi_shm_file_open): Set the umask when opening
332 shared files, so restrictive defaults don't prevent subsequent
333 processes re-opening them.
335 2007-10-18 Zoltan Varga <vargaz@gmail.com>
337 * atomic.h (InterlockedCompareExchange): Fix the ia64 version so it works for
338 negative values too. Hopefully fixes #332700.

342 * io-portability.c (_wapi_io_scandir): Only update the error
343 status of glob() when performing a secondary glob() if the first
344 returned an error. Fixes bug 325107.
346 2007-09-12 Marek Habersack <mhabersack@novell.com>
348 * io-portability.c: options_init moved to
349 utils/mono-io-portability.c
350 Do not initialize portability helpers here, it's done in
352 find_file and find_in_dir moved to utils/mono-io-portability.c

376 2007-09-03 Atsushi Enomoto <atsushi@ximian.com>
378 * processes.c, processes.h: added CreateProcessWithLogonW(). For now
379 it just calls CreateProcess().
380 * io-layer.h : CreateProcessWithLogonW() requires WINVER 0x0500
383 2007-08-23 Robert Jordan <robertj@gmx.net>
385 * processes.[c|h]: Implement Get|SetPriorityClass ().
386 Code is contributed under MIT/X11 license.

424 ending in '.*' so that files with no extension are also matched.
428 * wapi_glob.c: Reinstate WAPI_GLOB_APPEND, and add
429 WAPI_GLOB_UNIQUE to avoid matching the same entry twice when

472 * atomic.h: Enable for all hppa targets.
473 * Makefile.am: rename hppa_atomic.s to hppa_atomic.S so the preprocessor
475 * hppa_atomic.s: Renamed to ...
476 * hppa_atomic.S: ... and updated to work on both HPUX and Linux.
478 2007-06-13 Dick Porter <dick@ximian.com>
480 * handles.c (timedwait_signal_wait_cond): Alertable waits on
481 private handles are now interrupted by signalling the same
482 condition that would end the wait if the handle became signalled,
483 rather than polling. (Shared handles still have to poll.)
485 * threads.c (_wapi_thread_queue_apc): Interrupt the thread if it's
488 * handles-private.h (_wapi_handle_current_thread_set_waiting_on):
489 Helper functions to inform the APC queuing functions when threads

506 * io-portability.c (_wapi_g_dir_open): Don't propagate any errors
507 from the second call to g_dir_open, preserve the original error if
508 the second call still fails but clear the error if it succeeds.
510 2007-05-10 Dick Porter <dick@ximian.com>
512 * sockets.c (_wapi_recvfrom): Refine the fix to bug 75705 so EINTR
513 isn't returned if the remote end shuts down cleanly. Fixes zmd
514 and the second example in bug 75705.
516 2007-04-26 Dick Porter <dick@ximian.com>
518 * shared.c (_wapi_shm_semaphores_init): Need to check

524 * sockets.c (_wapi_recvfrom, socket_close): Force recvfrom() to
525 error if the socket is closed while the receive is blocking.
528 2007-04-13 Dick Porter <dick@ximian.com>
531 * shared.c: Complete the reimplementation of disabling of shared
532 memory, by not allocating sysv semaphores when shm disabling has
533 been requested (either at compile time or run time.)
535 * processes.c (CreateProcess): Don't synchronize locking across
536 processes when forking, when shared memory has been disabled.
538 2007-04-06 Andreas Faerber <andreas.faerber@web.de>

549 extended to match with case-insensitivity if needed.
552 * wapi_glob.c: Cut down implementation of glob(3), based on
555 2007-03-22 Dick Porter <dick@ximian.com>
557 * sockets.c (_wapi_connect): Do additional checks when connect(2)

576 and s390x ( bnc #237611 and bxc #80892 )
578 2007-03-05 Miguel de Icaza <miguel@novell.com>
580 * io.c (CreateFile): Use FILE_ATTRIBUTE_TEMPORARY to mean 0600
581 permissions. For 80688
583 (MoveFile): Use errno_copy here, just to avoid a potential
584 errno-changing code in the future from g_free.
586 Also, ignore EXDEV errors as they are handled immediately after
587 (avoid printing out an error).
591 Mon Feb 12 15:50:24 CET 2007 Paolo Molaro <lupus@ximian.com>
593 * shared.c: exit if semaphores can't be created (bug #80616).
595 2007-02-01 Geoff Norton <gnorton@customerdna.com>
597 * collection.c: NetBSD doesn't define PTHREAD_STACK_MIN.
599 2007-01-26 Dick Porter <dick@ximian.com>
602 * sockets.c (_wapi_getsockopt): Windows seems to not reset
603 SO_ERROR values when they're read, contrary to the documentation.
604 Fixes the new issues raised in bug 79878 (example in C showing
605 winsock behaviour attached to that bug.)
607 2007-01-15 Mark Mason <mason@broadcom.com
609 * atomic.h: add locking primitives for MIPS.
611 2007-01-11 Dick Porter <dick@ximian.com>
613 * sockets.c (_wapi_connect): Don't do the SO_BROADCAST setting
614 here, do it in managed code instead.
615 (_wapi_getsockopt): SO_RCVTIMEO and SO_SNDTIMEO use struct
616 timeval, which has a microsecond field, not milliseconds.
617 (_wapi_setsockopt): ditto.
618 (_wapi_setsockopt): Halve the SO_SNDBUF and SO_RCVBUF values on
619 Linux, as the kernel doubles whatever we set.
620 (_wapi_socket): Save socket domain, type and protocol so it can be
622 (socket_disconnect): Implement socket disconnect (closing the
623 socket, but keeping the file descriptor.)
624 (wapi_disconnectex): A basic implementation of DisconnectEx().
625 (wapi_transmitfile): A very basic implementation of
627 (WSAIoctl): Implement the SIO_GET_EXTENSION_FUNCTION_POINTER
630 * socket-private.h (struct _WapiHandle_socket): Record socket
631 domain, type and protocol info so it can be duplicated later.
633 * sockets.h (WSAID_DISCONNECTEX,WSAID_TRANSMITFILE): Structures
634 and defines needed to look up the DisconnectEx() and
635 TransmitFile() functions by GUID.
637 * error.c (errno_to_WSA): Change ETIMEDOUT mapping to
638 WSAETIMEDOUT; add EDESTADDRREQ.
640 * io-layer.h: Need mswsock.h on windows now.
642 2007-01-04 Miguel de Icaza <miguel@novell.com>
644 * io-portability.c (find_file): Fix a coverity warning (scanning
647 2006-12-31 Miguel de Icaza <miguel@novell.com>
649 * io-portability.c (find_file): Do not abort if an empty filename
650 has been passed. This fixes the case where MONO_IOMAP=all would
651 assert if Directory.Exists ("") was called.
653 Mon Dec 18 14:54:37 CET 2006 Paolo Molaro <lupus@ximian.com>
655 * processes.c: moved a free on the error path.
657 Thu Dec 14 21:42:39 CET 2006 Paolo Molaro <lupus@ximian.com>
659 * processes.c: fixed a few memory leaks when executing
662 Mon Nov 27 13:12:17 GMT 2006 Paolo Molaro <lupus@ximian.com>
664 * atomic.h: fix arm compare and exchange (bug #78500).
666 2006-11-23 Dick Porter <dick@ximian.com>
668 * process-private.h (struct _WapiHandle_process): Add 'waited'
671 * processes.c (process_wait): Check the 'waited' parameter not the
672 signalled state when testing if a process has already been waited
673 for, as the child process itself may set signalled when exiting.
676 * wapi-private.h (_WAPI_HANDLE_VERSION): Bump shared data version
678 * shared.c: Now the shared data version has been incremented we
679 can set the counter semaphore initial value correctly
681 2006-11-22 Dick Porter <dick@ximian.com>
683 * processes.c (process_wait): Cope when the background process
684 reaper gets the process we were waiting for. Special case for
685 waiting for our own process to exit. Fixes bug 77736.
687 2006-11-17 Dick Porter <dick@ximian.com>
689 * processes.c: Fix const correctness and typos that caused memory
692 2006-11-17 Miguel de Icaza <miguel@novell.com>
694 * processes.c (ShellExecuteEx): Check error after CreateProcess,
695 thanks to Dick for pointing this out.
697 2006-11-16 Miguel de Icaza <miguel@novell.com>
699 * processes.c (ShellExecuteEx): If we fail to create a process in
700 ShellExecute, then try to use the xdg-open command, and if that
701 fails, try to use the gnome-open command,
703 Refactor the code so that we do not have to duplicate all this
704 code, but instead use a ucs2-aware version of the code to do
707 2006-11-13 Dick Porter <dick@ximian.com>
709 * io.c (_wapi_stat_to_file_attributes): If the file is a symlink
710 add the FILE_ATTRIBUTE_REPARSE_POINT flag. This is an attempt to
711 follow the specs for the windows symlink support, but will
712 probably have to be reworked when I have test data from a vista
713 machine. Fixes bug 79887.
715 2006-11-11 Miguel de Icaza <miguel@novell.com>
717 * handles.c (CloseHandle): Cope here with the new value
718 INVALID_HANDLE_VALUE set on handles.
720 * processes.c (CreateProcess): Initialize the value of hThread to
721 be INVALID_HANDLE_VALUE on failure, not to be NULL. Improvement
724 2006-11-09 Dick Porter <dick@ximian.com>
726 * sockets.c (_wapi_select): Do some sanity checking on the
727 fd_sets, to avoid file descriptors > FD_SETSIZE.
728 (_wapi_FD_CLR, _wapi_FD_ISSET, _wapi_FD_SET): Avoid file
729 descriptors > FD_SETSIZE.
731 2006-10-27 Dick Porter <dick@ximian.com>
733 * io.c (GetFileAttributes): Force symlinks to directories to be
734 returned as a regular file. Fixes bug 79733.
736 2006-10-18 Miguel de Icaza <miguel@novell.com>
738 * io-portability.c (find_in_dir): First string dup, then closedir.
740 2006-10-12 Dick Porter <dick@ximian.com>
742 * processes.c (_wapi_process_reap): Unref a process handle if we
743 reaped it, found by Zoltan. Fixes bug 79286.
744 (process_wait): Don't wait again if we've already waited for a
747 2006-10-11 Sergey Tikhonov <tsv@solvo.ru>
749 * atomic.h: Fix atomic decrement.
751 * mini/cpu-alpha.md: Use native long shift insts
753 * mono/mono/mini/tramp-alpha.c: Implemented
754 mono_arch_patch_delegate_trampoline method
756 * Started work on using global registers
758 * Use byte/word memory load/store insts if cpu supports it
763 2006-10-09 Zoltan Varga <vargaz@gmail.com>
765 * handles.c (timedwait_signal_poll_cond): Add an alertable parameter, and if it
766 is FALSE, avoid busy waiting.
768 * wait.c: Add an alertable parameter to the wait routines.
770 2006-10-06 Miguel de Icaza <miguel@novell.com>
772 * io-portability.c (find_file): Rename from
773 MONO_IO_PORTABILITY_HELP to MONO_IOMAP.
775 2006-10-03 Dick Porter <dick@ximian.com>
778 * io-portability.c: Optional portability helpers and wrapped
779 system calls to try to cope with windows filenames in
782 * io.c: Use the wrapped system calls
784 2006-09-01 Zoltan Varga <vargaz@gmail.com>
786 * critical-sections.h critical-sections.c: Make Enter/LeaveCriticalSection a macro
787 since they are perf critical.
789 * atomic.h: Applied patch from Jakub Boqusz <qboosh@pld-linux.org>.
790 Add atomic ops implementation for alpha.
792 2006-08-11 Dick Porter <dick@ximian.com>
794 * processes.c (_wapi_process_reap): Avoid a deadlock by setting
795 process termination details in an outer loop, not the
796 _wapi_search_handle() one.
798 2006-08-10 Dick Porter <dick@ximian.com>
800 * threads.c (_wapi_thread_queue_apc)
801 (_wapi_thread_dispatch_apc_queue): Use a process-local mutex here
802 instead of the cross process semaphore. We already check that
803 access to the APC queue is within the owning process so there's no
804 need to protect from other processes. Avoids a global deadlock
805 when a thread is aborted while it holds the handle semaphore
807 (_wapi_thread_apc_pending): Hide an annoying message which can
808 happen if a thread handle has been blown away at process shutdown
809 while it is in an alertable wait.
811 Both problems seen while shutting down monodevelop.
813 2006-07-25 Dick Porter <dick@ximian.com>
815 * shared.c (_wapi_shm_file): Remove '/' characters from the uname
816 results. Fixes bug 78917.
818 2006-07-20 Dick Porter <dick@ximian.com>
820 * threads.c (_wapi_thread_set_termination_details): Improve the
821 test for already-disposed thread handles, and hold the lock around
822 the mutex abandoning.
824 2006-07-17 Dick Porter <dick@ximian.com>
826 * processes.c (CreateProcess): Don't change directory unless a new
827 one has been specified. Fixes bug 78751.
829 2006-07-06 Dick Porter <dick@ximian.com>
831 * io.c (_wapi_stat_to_file_attributes): Do a better job at
832 figuring out the file attributes
833 (_wapi_set_last_path_error_from_errno): New helper function to
834 turn errno into w32 error codes that handles the differences
835 between file and directory errors
836 (file_setendoffile): Try turning off the extra write used to
837 extend files, because we probably don't need it on any modern
838 platform. If it is needed though, we also need to lseek the file
840 (CreateFile): Treat character-special devices as a console handle,
841 because they can't be seeked
842 (CopyFile): If fail_if_exists is set, then the destination needs
843 to be opened with O_EXCL
844 (CopyFile): If fail_if_exists is not set and the destination
845 already exists, then we should set the ERROR_ALREADY_EXISTS error
846 even though we return success
847 (stdhandle_create): STD_INPUT_HANDLES cannot be written to
848 (GetStdHandle): Rework without using mono_once, so console handles
849 can be properly closed and reopened.
850 (mono_io_scandir): Only override errno with EACCES when the
851 directory actually exists
852 (FindFirstFile): Set ERROR_FILE_NOT_FOUND when no files are
854 (FindClose): Cope with NULL handles
855 (CreateDirectory): When the target already exists, just return an
856 error. It's the caller's job to figure out what to do.
857 (SetCurrentDirectory): Cope with a NULL path
858 (RemoveDirectory, GetFileAttributes, GetFileAttributesEx,
859 SetFileAttributes, FindFirstFile, DeleteFile, MoveFile, CopyFile,
860 CreateFile): Set path error correctly
862 * handles.c (CloseHandle): Kludge to try and cope with passing a
865 * error.h: Add NO_ERROR as an alternative to ERROR_SUCCESS
867 * uglify.h: Added some more typedefs
869 2006-07-05 Dick Porter <dick@ximian.com>
871 * io.c (GetFileAttributes, GetFileAttributesEx): Cope with
872 dangling symlinks. Fixes bug 78664.
874 2006-06-23 Dick Porter <dick@ximian.com>
876 * handles.c (handle_cleanup):
877 * threads.c: Clean up threads properly when we're forcibly
878 removing the handle entries from the shared file in
879 handle_cleanup(). Fixes bug 78241, for real this time.
881 2006-06-15 Neale Ferguson <neale@sinenomine.net>
883 * atomic.h: More tinkering with InterlockedExchange/InterlockedCompareExchange
886 2006-06-14 Neale Ferguson <neale@sinenomine.net>
888 * atomic.h: Fix atomic exchange pointer operations for s390x - these
889 were broken as they used 32-bit instructions rather than their 64-bit
892 2006-06-14 Dick Porter <dick@ximian.com>
894 * processes.c: Don't run the atexit handlers when bailing out
897 2006-06-14 Dick Porter <dick@ximian.com>
899 * wait.c: Fix stupid typo shown up by gcc 4.1.1, = not ==
907 * collection.c: Fix a bunch of signed/unsigned warnings from gcc
910 2006-06-09 Neale Ferguson <neale@sinenomine.net>
912 * atomic.h: Fix atomic operations for s390x (not really broken
913 but changed to use full 64-bit opcodes).
915 2006-05-24 Dick Porter <dick@ximian.com>
917 * processes.c (process_set_current): Don't take an extra reference
918 if we have to create our own process handle. Fixes bug 78241
921 * threads.c (_wapi_thread_signal_self): Renamed from
922 _wapi_thread_abandon_mutexes, also sets the thread state to
923 signalled and drops a reference. Called by the runtime when the
924 main thread cleans itself up.
926 * handles.c (handle_cleanup): As a last resort, unref every shared
927 handle as the process is now exiting.
929 2006-05-16 Dick Porter <dick@ximian.com>
931 * processes.c (process_set_termination_details): Unref the handle
932 when we've stored the exit details. Fixes the rest of 78241.
934 2006-05-12 Dick Porter <dick@ximian.com>
936 * threads.c: Implement pseudo handles, making GetCurrentThread()
937 match MS behaviour. Notice when attached threads exit, and unref
938 the handle. Fix usage of GetCurrentThread() in other places.
940 * handles.c (DuplicateHandle): Implement a basic form of
943 * wait.c: Fix usage of GetCurrentThread() throughout, and cope
946 2006-04-26 Miguel de Icaza <miguel@novell.com>
948 * io.c (file_close): Oops, do not use DeleteFile which expects
949 unicode, instead use unlink directly
951 Add support for the new FileOptions bits on .NET 2.0.
953 It might be good if Dick reviews these changes.
955 * io.c (file_close): If DeleteOnClose is set, then delete the file
957 (CreateFile): Do not support encryption per user.
959 If posix_fadvise exists, pass hints on sequential scan and random
960 access. Did not figure out what WRITE_THROUGH maps to.
962 2006-04-26 Dick Porter <dick@ximian.com>
964 * sockets.c (WSAIoctl): Check the output buffer is valid before
967 * handles.c (_wapi_search_handle): Set shared pointer if we find a
968 shared handle that has been already opened.
970 2006-04-21 Dick Porter <dick@ximian.com>
972 * threads.c (GetCurrentThread): Reference the handle if we return
973 an already-known thread.
975 2006-04-07 Dick Porter <dick@ximian.com>
977 * processes.c: Fix build for older glib.
979 2006-04-06 Dick Porter <dick@ximian.com>
981 * processes.c (CreateProcess): Add a reference to the child
982 process' handle, so it won't be destroyed if this process closes
983 its copy of the handle. Fixes bug 77393.
985 * processes.c (process_set_current): Fall through to creating a
986 new one if the handle lookup fails.
988 * processes.c (_wapi_process_signal_self):
989 * handles.c (handle_cleanup): The process is exiting, so set the
990 handle state for this process to signalled. This should let other
991 non-related processes wait for this handle.
993 * handles.c (_wapi_search_handle): Don't search shared handles in
996 * collection.c (collection_thread): No need to do a collection
997 scan straight away, do the waiting first.
999 2006-04-06 Dick Porter <dick@ximian.com>
1001 * shared.c: Fix parameters in semctl () call.
1003 2006-03-28 Zoltan Varga <vargaz@gmail.com>
1005 * atomic.h atomic.c: Applied patch from David S. Miller
1006 <davem@davemloft.net>: Reimplement Interlocked* primitives on sparc
1007 using CAS/CASx when __GNUC__, else we will fall back to the generic
1010 2006-03-27 Dick Porter <dick@ximian.com>
1012 * shared.c (_wapi_shm_file_open): Break out of a loop if the
1013 shared file is smaller than expected. (We loop a few times in
1014 case another process is in the middle of creating the file.)
1016 2006-03-22 Dick Porter <dick@ximian.com>
1021 * shared.c: Delete the semaphores and shared files when the last
1022 process has finished with them
1024 2006-03-15 Dick Porter <dick@ximian.com>
1032 * threads.c: Explicitly initialise the handle ops struct
1034 2006-03-14 Dick Porter <dick@ximian.com>
1036 * handles-private.h:
1039 * handles.c: Add a 'prewait' stage to the handle waiting, to give
1040 waiting threads a chance to check for bogus states before
1043 * mutexes.c (namedmutex_prewait): Use the prewait stage to check
1044 for named mutexes that have been abandoned in a locked state (eg
1045 if a process exited abnormally while owning the mutex) and
1046 override it if needed.
1048 2006-03-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1050 * wait.c: speed up WaitFor* when the timeout is 0.
1052 2006-03-03 Dick Porter <dick@ximian.com>
1054 * processes.c (ShellExecuteEx): Cope when some of the parameters
1057 2006-02-27 Dick Porter <dick@ximian.com>
1061 * threads.c: Comparing pthread_t with == is not portable, so use
1064 Thu Feb 23 18:47:20 GMT 2006 Paolo Molaro <lupus@ximian.com>
1066 * *.h, *.h: patch from Dick to make Linuxthreads systems work again.
1068 2006-02-22 Dick Porter <dick@ximian.com>
1071 * threads.c: There's no need to use the timed-thread support code
1072 any more, as we aren't using the timed join. This greatly
1073 simplifies thread setup, and fixes a memory leak (bug 77521).
1075 Don't bother to store thread IDs in a hash table, use TLS instead.
1076 The one case that needs to look up the handle of a different
1077 thread (OpenThread()) can do the extra work itself. Fixes bug
1080 * handles.c (_wapi_search_handle): Add a reference when returning
1081 a private handle (shared handles are already reffed.)
1083 2006-02-17 Dick Porter <dick@ximian.com>
1085 * handles-private.h:
1086 * handles.c: Check handle values passed to array lookups. Fixes
1089 2006-02-09 Dick Porter <dick@ximian.com>
1091 * threads.c: Cope with the problems caused by attaching already
1092 existing threads - they don't get the infrastructure to clean up
1093 after themselves, especially the ID to handle hash. This fixes
1096 2006-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1098 * shared.c: use MONO_SHARED_HOSTNAME as a substitute for gethostname()
1099 when creating the shared files in the .wapi directory. Fixes bug #77371.
1101 2006-02-02 Martin Baulig <martin@ximian.com>
1103 * threads.c: Removed the `WITH_INCLUDED_LIBGC' section; it has
1104 never been used so far.
1106 * timed-thread.h (TimedThread): Removed the `stack_ptr' field; it
1107 has only been used by the removed code.
1109 2006-01-03 Neale Ferguson <neale@sinenomine.net>
1111 * atomic.h: Correct s390x definitions and eliminate compiler warnings.
1113 2006-01-03 Sebastien Pouliot <sebastien@ximian.com>
1115 * io.c: Patch _wapi_stat_to_file_attributes against bug #76966, where
1116 sockets could be considered as directory.
1118 2005-12-23 Dick Porter <dick@ximian.com>
1122 * semaphores.c: Implement OpenSemaphore
1125 * mutexes.h: Implement OpenMutex
1131 * event-private.h: Implement named events. Implement OpenEvent.
1133 2005-12-15 Dick Porter <dick@ximian.com>
1135 * processes.c (CreateProcess): The pipe-based cross-process
1136 exclusion technique was trying to write NULL buffers when appname
1137 was NULL (eg when coming from ShellExecuteEx,) which usually
1138 succeeded even though EFAULT was returned - but sometimes it
1139 failed. This meant that the child process could block forever on
1140 the pipe read. Replace it with the simpler shared handle
1141 semaphore protection used everywhere else. This showed up with
1142 the test case in bug 76684.
1144 Tue Dec 13 11:41:49 GMT 2005 Paolo Molaro <lupus@ximian.com>
1146 * shared.c: fallback to private mmap when shared mmap doesn't work
1149 2005-12-06 Dick Porter <dick@ximian.com>
1153 * semaphore-private.h:
1154 * semaphores.c: Implement named semaphores
1156 2005-11-24 Dick Porter <dick@ximian.com>
1158 * processes.c (GetProcessId): Implement GetProcessId()
1160 2005-11-17 Dick Porter <dick@ximian.com>
1163 * processes.c: Implement ShellExecuteEx as a wrapper around
1166 2005-11-11 Dick Porter <dick@ximian.com>
1168 * threads.c: Give mutex abandoning its own exported function, so
1169 it can be called when the runtime is cleaning up.
1171 * handles.c (_wapi_search_handle_namespace): Do a handle
1172 collection befre starting to check namespace strings, so that any
1173 stale cruft gets removed.
1175 2005-11-11 Dick Porter <dick@ximian.com>
1177 * threads.c: Move thread handles back into the shared space.
1179 * handles.c (_wapi_handle_unref): Add support for shared handles
1180 with close() handlers
1182 2005-11-04 Dick Porter <dick@ximian.com>
1184 * sockets.c (ioctlsocket): Use select instead of if to avoid a
1185 type promotion problem on 64bit freebsd. Based on patch by Lou
1186 Kamenov <kamenovl@gmail.com>, fixes bug 76447.
1188 2005-11-04 Dick Porter <dick@ximian.com>
1190 * io.c (file_write): Only do the file locking if
1191 MONO_STRICT_IO_EMULATION is set.
1193 2005-10-21 Dick Porter <dick@ximian.com>
1196 * handles.c (_wapi_lookup_handle): Cope when the shared part of a
1197 handle has been deleted.
1198 (_wapi_handle_unref): And when the deleted shared part is pointed
1199 to as a handle is deleted
1201 2005-10-20 Dick Porter <dick@ximian.com>
1203 * processes.c (process_set_current): If the expected process
1204 handle slot doesn't contain the correct pid, create a new handle.
1206 * handles.c (_wapi_search_handle): When the search doesn't find
1207 anything, return failure instead of the last handle we looked at.
1208 (_wapi_handle_ref, _wapi_handle_unref): Don't try to ref or unref
1209 unused handles (makes tracking refcounting bugs easier.)
1211 2005-10-19 Dick Porter <dick@ximian.com>
1214 * handles-private.h:
1218 * collection.c (_wapi_handle_collect): Remove the shared handle
1219 indirection layer, and use locking instead. Delete other
1220 complexity that is no longer needed. Refcount shared handles and
1221 delete them when needed, but keep the timestamps so that orphaned
1222 handles will be cleaned up eventually.
1224 * shared.c (_wapi_shm_file): Add processor, OS and struct size
1225 info to the shared file names, to cope with dual-boot and 32/64bit
1226 size issues. Fixes bug 75839.
1228 * wait.c (WaitForMultipleObjectsEx): No need to distinguish
1229 between shared handles and private, as the wait functions cope
1230 with both together now.
1232 2005-10-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1234 * io.c: removed NO_SIGPIPE macro.
1235 * sockets.c: no need for MSG_NOSIGNAL or ignoring SIGPIPE.
1237 2005-10-11 Dick Porter <dick@ximian.com>
1239 * sockets.c (_wapi_getsockopt): Translate SO_ERROR results into
1242 * error.c (errno_to_WSA): Don't return a bogus error if someone
1243 asks to translate errno 0.
1245 2005-10-11 Dick Porter <dick@ximian.com>
1247 * handles.c: Fix several race conditions
1249 2005-10-11 Miguel de Icaza <miguel@novell.com>
1251 * io.c: no need to block SIGPIPE anymore, as it is ignored.
1253 2005-10-05 Dick Porter <dick@ximian.com>
1255 * threads.c (_wapi_thread_own_mutex, _wapi_thread_disown_mutex):
1256 Keep a reference to mutexes owned by threads, so they won't be
1257 destroyed prematurely. Fixes dotmsnclient crash.
1259 2005-09-26 Sebastien Pouliot <sebastien@ximian.com>
1261 * io.c: Apply patch from #76192 (Can't write files past 2gb on AMD64
1262 (x86_64)) for Brion on IRC (Dick approved it).
1264 2005-09-23 Dick Porter <dick@ximian.com>
1266 * processes.c: Don't wait for processes that have already been
1267 signalled; also fix typo.
1269 * handles.c: Improve locking inside new handle and handle
1270 searching functions.
1272 2005-09-20 Dick Porter <dick@ximian.com>
1275 * processes.c: Periodically waitpid for known process IDs. Fixes
1278 2005-09-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1281 (CreateFile): if the file is a named pipe, treat the handle as a pipe,
1282 not as a file. Fixes bug #76075.
1284 2005-08-27 Zoltan Varga <vargaz@gmail.com>
1286 * atomic.h: Add support for intel icc.
1288 2005-08-25 Zoltan Varga <vargaz@gmail.com>
1290 * io-layer.h: Include winbase.h not WinBase.h.
1292 2005-08-19 Dick Porter <dick@ximian.com>
1294 * threads.c, threads.h, thread-private.h: Use a gsize to store the
1295 thread ID, so it can hold a 64 bit value if needed.
1297 2005-07-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1299 * error.c: map ENOENT to WSAECONNREFUSED. It might happen when
1300 connecting to unix sockets. Closes bug #75632.
1302 2005-07-05 Dick Porter <dick@ximian.com>
1304 * io.c: Make sure SIGPIPE is ignored when calling write(2).
1305 Prevents the runtime exiting when writing to a closed pipe,
1308 2005-06-30 Dick Porter <dick@ximian.com>
1310 * shared.c (_wapi_shm_semaphores_init): Add some helpful error
1311 messages when semget () fails due to lack of resources.
1313 2005-06-21 Dick Porter <dick@ximian.com>
1318 * threads.c: Keep a list of owned mutexes in each thread handle,
1319 so that it is easier to abandon them when the thread exits.
1320 Removes a bottleneck when multiple threads are finishing in
1323 2005-06-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1325 * io.c: (GetLogicalDrives) when a bogus line is read, don't leak memory.
1326 When the buffer has not enough space, close the file before returning.
1328 2005-06-09 Duncan Mak <duncan@novell.com>
1330 * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to
1331 all public headers. Fixes #74919.
1333 2005-05-30 Zoltan Varga <vargaz@freemail.hu>
1335 * atomic.h: Add IA64 atomic ops.
1337 2005-05-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1339 * processes.c: make ExitCode be valid even if the user didn't call
1340 WaitForExit() and is just polling on HasExited.
1342 2005-05-17 Dick Porter <dick@ximian.com>
1344 * io.c (file_getfilesize): Clear the error value, so that files
1345 with sizes with the low bits 0xFFFFFFFF can be distinguished from
1348 2005-05-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1350 * shared.c: forgot to ignore a warning.
1352 2005-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1354 * shared.c: don't display warnings after reboots.
1356 2005-05-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1358 * sockets.c: on windows, getsockopt/setsockopt for send/receive timeout
1359 use an integer in milliseconds. We were using a struct timeval.
1361 2005-05-06 Dick Porter <dick@ximian.com>
1363 * handles-private.h:
1370 * collection.h: Use SysV semaphores for managing access to the
1371 shared memory - in return for the ludicrous api we get
1372 synchronisation primitives that can be cleaned up by the kernel
1373 even when a process quits unexpectedly. This removes the
1376 2005-05-05 Lluis Sanchez Gual <lluis@novell.com>
1378 * handles.c: Always use polling in the waits, since
1379 mono_cond_timedwait can't be interruped by the thread abort signal.
1381 2005-04-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1383 * events.c: calling Set on AutoResetEvent several times has the same
1384 effect as calling it only once if no thread is waiting for it.
1386 2005-04-29 Dick Porter <dick@ximian.com>
1388 * processes.c (EnumProcesses): Use a GArray instead of a GPtrArray
1389 now it's storing pids not handles, also fixes memory leak caused
1390 by unclear glib documentation.
1392 * sockets.c (WSACleanup): Remove unused variable
1394 2005-04-29 Dick Porter <dick@ximian.com>
1396 * handles.c (_wapi_handle_check_share_by_pid): For systems that
1397 don't have file descriptor info in /proc check that the original
1398 opener of a file is still there, if a share violation would
1401 2005-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1404 * handles-private.h: added _wapi_handle_forecch that loops through all
1405 the handles and call a callback function when a handle of the given
1408 * sockets.c: no need to keep open sockets in an array, as we have them
1409 in the handles structure.
1413 2005-04-28 Dick Porter <dick@ximian.com>
1415 * processes.c: Cope with handles that are only around for as long
1416 as the search is running. If we're searching for process handles,
1417 check to see if the process is still running and signal it if not.
1419 * handles.c (_wapi_search_handle): Search in the shared space as
1420 well. Fixed bug 74752.
1423 * handles.c (_wapi_handle_new_from_offset):
1424 _wapi_handle_new_for_existing_ns () was doing exactly the same as
1425 this, so deleted it.
1427 2005-04-26 Dick Porter <dick@ximian.com>
1429 * handles.c: Fix stupid thinko where if a new shared handle is
1430 created but a collection was needed to free some space, it
1431 returned an error anyway. Should fix the messages shown in bug
1434 2005-04-25 Dick Porter <dick@ximian.com>
1436 * handles.c (_wapi_handle_check_share): Only consider mono
1437 processes when looking to see if a file is still being held open,
1438 while checking share permissions.
1440 2005-04-25 Dick Porter <dick@ximian.com>
1444 * wapi-private.h (struct _WapiHandleOps):
1445 * handles.c (_wapi_handle_unref): When destroying handles, save
1446 the handle data and call the close function only after the array
1447 slot has been cleared. This prevents race conditions with file
1448 descriptors, fixing bug 74713.
1450 * mutexes.c: Delete the handle close functions, they didn't do
1453 * error.c (_wapi_get_win32_file_error): Add a mapping for EINTR so
1454 the "Unknown error" g_warning doesn't get displayed.
1456 2005-04-25 Dick Porter <dick@ximian.com>
1459 * threads.c: Make thread handles process-private for now to take
1460 some of the space pressure off the shared memory, while I work on
1463 2005-04-21 Dick Porter <dick@ximian.com>
1465 * handles.c (_wapi_handle_check_share): Make sure there is a "fd"
1466 dir in /proc before blowing away handle info. Fixes bug 74649.
1468 2005-04-21 Dick Porter <dick@ximian.com>
1470 * wait.c (WaitForMultipleObjectsEx): Implement special waits
1472 * handles.c (_wapi_handle_wait_signal_poll_share): Don't return a
1473 timeout, just wait briefly for the private signals and let the
1474 waiting thread test again. This prevents us missing shared
1477 2005-04-21 Dick Porter <dick@ximian.com>
1479 * collection.h (_WAPI_HANDLE_COLLECTION_EXPIRED_INTERVAL): Reduce
1480 the time before a slot is considered too old and deleted. This is
1481 a workaround while I come up with a proper fix.
1483 2005-04-21 Dick Porter <dick@ximian.com>
1488 * handles.c (_wapi_handle_new): Turn assertions into errors.
1490 * collection.c (_wapi_handle_collect): Use symbols not magic
1491 numbers for timeout values
1493 2005-04-19 Dick Porter <dick@ximian.com>
1497 * handles.c (_wapi_handle_count_signalled_handles)
1498 * handles-private.h (_wapi_handle_shared_lock_handle): Use new
1499 shared handle locks in critical sections.
1501 * handles.c (_wapi_handle_new_for_existing_ns): Reuse old handles
1502 if there is already one there.
1504 * handles.c (_wapi_handle_ref): It was possible for a process to
1505 exit before getting around to updating shared handle timestamps,
1508 Tue Apr 19 16:25:47 CEST 2005 Paolo Molaro <lupus@ximian.com>
1510 * threads.c: fix lookup of the thread id in the has table:
1511 always use the id value, not the pointer to the id.
1513 2005-04-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1515 * handles.c: fix handle returned in _wapi_handle_search_handle. Dick
1518 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1520 * io-layer/sockets.c: FIONBIO with a TRUE argument means we want
1521 non-blocking IO, not the other way around.
1523 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1527 * handles-private.h: GetFileType wasn't checking if we have memory
1528 allocated for the handle before dereferencing it. Fixes a FileStream
1531 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1535 * handles-private.h: we were calling g_renew to expand the handle array,
1536 but that might move the memory and we might have pthread conditions or
1537 mutexes in the original memory area that are being used. Now instead of
1538 expanding an existing array, we just create new ones and keep a list of
1539 them. Access to _wapi_private_handles had to be modified accordingly.
1541 2005-04-15 Dick Porter <dick@ximian.com>
1543 * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN
1545 2005-04-14 Raja R Harinath <rharinath@novell.com>
1547 * wapi-private.h: Remove reference to 'daemon-private.h'.
1549 Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro <lupus@ximian.com>
1551 * atomic.h: applied patch from mass@akuma.org (David Waite)
1552 to fix InterlockedExchangeAdd.
1553 Fixed a few other functions, including InterlockedCompareExchange()
1554 which was miscompiled by gcc with optimizations enabled.
1556 2005-04-13 Dick Porter <dick@ximian.com>
1558 * io.c (share_check):
1559 * handles.c (_wapi_handle_check_share): Refine the file check so
1560 that sharing violations within the same process don't cause
1563 2005-04-13 Dick Porter <dick@ximian.com>
1565 * io.c (FindFirstFile): Fix bugs introduced with the merge (bug
1568 2005-04-12 Dick Porter <dick@ximian.com>
1570 The daemon-less io-layer. Extensive lowlevel changes in
1571 handles.c, requiring some corresponding changes in other files
1572 calling these functions. Private_foo structures have been
1575 File descriptor handling differences account for most of the
1576 changes in io.c and sockets.c.
1580 * mutexes.c: Named mutexes are now a distinct type.
1581 * atomic.h: Fix a PPC uninitialised variable warning.
1582 * wait.c: Check conditions before waiting on a condition variable.
1583 * processes.c: Handle process fork and wait without a daemon
1584 (though this has the limitation of only being able to wait for
1587 2005-04-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1594 * sockets.h: removed dead code that deals with async IO.
1596 2005-03-30 Zoltan Varga <vargaz@freemail.hu>
1598 * atomic.c (InterlockedIncrement): Fix fallback implementation of
1599 InterlockedIncrement and InterlockedDecrement. Fixes #74228.
1601 2005-03-29 Sebastien Pouliot <sebastien@ximian.com>
1603 * io-layer.h: Add required header files for compiling with VS.NET.
1605 2005-03-17 Miguel de Icaza <miguel@novell.com>
1607 * io.c: don't fail on NFS when there are no more locks available.
1609 2005-03-09 Dick Porter <dick@ximian.com>
1611 * error.c (_wapi_get_win32_file_error): ENFILE and EMFILE should
1612 map to ERROR_TOO_MANY_OPEN_FILES, not ERROR_NO_MORE_FILES. Fixes
1615 2005-03-09 Dick Porter <dick@ximian.com>
1617 * daemon.c (process_process_fork): Initialise the handle data
1618 before using it in the error case. This is probably the error
1619 we're working around in the previous change. Spotted by Taru Jain
1620 <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.
1622 2005-03-07 Dick Porter <dick@ximian.com>
1624 * daemon.c: It looks like g_shell_parse_argv() can return
1625 argv[0]=NULL somehow, yet still not give an error. Make sure we
1626 don't pass NULL to strrchr(), working around a segfault that
1627 showed up on ZLM testing.
1629 2005-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1631 * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is
1632 the expected error code showed by the test case in bug #73053.
1634 2005-02-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1636 * io.c: another leftover.
1638 Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1640 * io.c: fixed logic in checking errno in rev 40815.
1642 Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1644 * threads.c: we don't depend on the GC checking tls
1646 * processes.c: remove unused ref to GC headers.
1648 Thu Feb 17 19:57:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1650 * io.c: remove _wapi_thread_cur_apc_pending () checks
1651 when the siscall should return immediatly and handle
1652 the case when a syscall is interrupted without
1653 erroring out, but returning a 0 read/write if possible.
1654 Still the cases of read from file need to be handled.
1656 Tue Feb 8 18:28:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1658 * threads.c: make people test with 1 MB stack per thread.
1660 2005-01-17 Dick Porter <dick@ximian.com>
1662 * timefuncs.h: Make WapiFileTime endian-aware, as it's often
1663 cast to and from 64bit ints. Fixes bug 71213.
1665 2005-01-11 Dick Porter <dick@ximian.com>
1667 * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
1670 Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>
1672 * atomic.h: Fix functions on s390.
1674 Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>
1676 * atomic.h: fix some functions on ppc (tests/interlocked.cs).
1678 2005-01-10 Dick Porter <dick@ximian.com>
1680 * misc.c (_wapi_calc_timeout): Guard against overflow when
1681 calculating timeouts. This makes waiting with a large
1682 (Int32.MaxValue) timeout not return immediately.
1684 2004-12-23 Ben Maurer <bmaurer@ximian.com>
1686 * io.c (io_ops): make this `const' so it is shareable (well, only
1687 really shareable if it is statically linked...)
1689 Mon Dec 20 11:58:33 CET 2004 Paolo Molaro <lupus@ximian.com>
1691 * threads.c, threads.h: add accessor to get the pthread_key_t for
1694 2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1696 * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS
1697 if it exists and is not the same as 'src'.
1699 2004-12-01 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1701 * atomic.h : Fix InterlockedCompareExchange for s390/s390x.
1703 2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1705 * processes.c: unquote the cmd path, allow for ' or " when quoting and
1706 pass the quoted program name to the daemon, otherwise the call to
1707 g_shell_unquote in the daemon will break things up.
1709 2004-10-14 Dick Porter <dick@ximian.com>
1711 * sockets.c (_wapi_accept): Revert the previous change. We now
1712 set the accepted socket to have the same blocking status as the
1713 listening socket in managed code. This follows MS behaviour.
1715 2004-10-14 Dick Porter <dick@ximian.com>
1717 * sockets.c (_wapi_accept): On Darwin, make sure a newly
1718 accept()ed socket is blocking. Fixes bug 67355, patch by
1719 grompf@sublimeintervention.com.
1721 2004-10-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1723 * system.c: check the number of online processors instead of the
1724 existing ones. Sanitize return value if it's an error.
1726 2004-10-03 Ben Maurer <bmaurer@ximian.com>
1728 * system.c: Add support for getting the # of cpus.
1730 2004-09-28 Dick Porter <dick@ximian.com>
1732 * io.c (pipe_close_private): Fix one small typo in the last change
1733 that totally hosed process creation with redirected pipes.
1735 2004-09-24 Dick Porter <dick@ximian.com>
1742 * handles-private.h: Cope when a file descriptor is reused while
1743 the handle that thought it owned it is still referenced, instead
1744 of asserting. Probably fixes bug 66479, though we've been unable
1747 2004-09-09 Dick Porter <dick@ximian.com>
1750 * io.c: Set error codes everywhere.
1752 2004-09-06 Dick Porter <dick@ximian.com>
1754 * handles.c (_wapi_handle_unref): Reset the private record's type
1755 (CloseHandle): Check for a fd mapping failure, and return FALSE.
1756 (_wapi_handle_process_fork): Fix long-standing bug in checking
1757 handle return values. Also do the required bookkeeping with the
1758 new process's handles.
1760 * daemon.c: When creating a new process's handles, check whether
1761 the shared space needs to be increased
1763 2004-09-05 Zoltan Varga <vargaz@freemail.hu>
1765 * shared.c (_wapi_shm_file): Fix leaking of filename.
1767 2004-08-19 Dick Porter <dick@ximian.com>
1769 * handles.c (_wapi_handle_count_signalled_handles): Fix thinko
1770 introduced with the fd offset stuff: unlock handles properly when
1771 backing off. Fixes the monologue hang at exit.
1773 2004-08-18 Dick Porter <dick@ximian.com>
1776 * io.c: Check that new fds fit in the table, return error if not
1778 * daemon.c (_wapi_daemon_main):
1779 * handles.c (shared_init): Have all processes agree on a size for
1782 2004-08-17 Dick Porter <dick@ximian.com>
1784 * daemon.c (process_new):
1785 * handles.c (_wapi_handle_new_internal): Cope when the space
1786 reserved for file descriptors is larger than the shared segment
1787 size. Fixes the crash reported when running mono under gdb on
1790 2004-08-16 Dick Porter <dick@ximian.com>
1794 * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
1795 error checking with passed-in file descriptors.
1797 2004-08-11 Dick Porter <dick@ximian.com>
1800 * io.c: Returned handle values are the file descriptor the handle
1804 * handles-private.h:
1805 * daemon.c: Reserve the range of handles that can have the same
1806 values as file descriptors. These won't be used, but the values
1807 will be used as file, console, pipe or socket handles. The fd to
1808 handle mapping is done internally and is invisible to users.
1811 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
1812 reserve a chunk of handle space.
1814 2004-08-04 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1816 * atomic.h: add support for 64-bit S/390
1818 2004-07-22 Dick Porter <dick@ximian.com>
1821 * threads.c: Move the destruction of the internal thread data to
1822 after the thread has been joined. Fixes bug 61418.
1824 2004-07-14 Dick Porter <dick@ximian.com>
1826 * wait.c (test_and_own): When not waiting for all handles to
1827 become signalled, only own and return the lowest. All the
1828 documentation suggests that the old way was correct, but
1829 experimentation shows it actually works like this. Patch by
1830 Sébastien Robitaille
1831 (sebastien.robitaille@croesus.com), fixes bug 61511.
1833 2004-07-09 Ben Maurer <bmaurer@ximian.com>
1835 * threads.c: register roots for gc
1837 2004-07-08 Dick Porter <dick@ximian.com>
1839 * io.c (file_seek): If there is a high 32bit offset part, make
1840 sure the low part isn't sign-extended. Set error codes when
1841 returning failure. Fixes bug 61131.
1843 2004-07-06 Dick Porter <dick@ximian.com>
1845 * io.c (file_setfiletime): Check for underflow when converting to
1846 time_t values. Set error codes when returning failure. Fixes bug
1849 2004-07-05 Dick Porter <dick@ximian.com>
1851 * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable.
1853 * daemon.c (unref_handle): Only destroy a handle if all processes
1854 have released it, not just the current one. Fixes bug 60887.
1856 2004-06-30 Zoltan Varga <vargaz@freemail.hu>
1858 * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
1859 to prevent warnings.
1861 2004-06-24 Dick Porter <dick@ximian.com>
1863 * mutexes.c: Indicate when a named mutex was reused
1865 2004-06-24 Dick Porter <dick@ximian.com>
1867 * threads.c (SuspendThread):
1868 * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a
1869 while loop. See bug 58161.
1871 Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro <lupus@ximian.com>
1873 * io.c: don't use sharemode for on-disk file permissions: it's used
1874 for shared access to the open file.
1876 2004-06-22 Dick Porter <dick@ximian.com>
1878 * events.c (CreateEvent): When creating an auto-reset event that
1879 is initially owned, make sure the set count starts at 1.
1881 2004-06-18 Dick Porter <dick@ximian.com>
1884 * events.c: Auto-reset events need to release one thread for each
1885 time SetEvent() is called. Fixes bug 41292.
1889 * mutexes.c: Scan for mutexes that are still locked by a thread
1890 when it exits. Fixes the MS demo app linked by bug 41292.
1892 * wait.c (test_and_own): Make sure a handle is signalled before it
1895 2004-06-16 Dick Porter <dick@ximian.com>
1897 * timed-thread.c: Call the thread cleanup exit routine before taking
1898 the join mutex, because this could deadlock if another thread tries
1899 to join in the meantime. This fixes the hang-at-exit problem seen
1902 2004-06-03 Lluis Sanchez Gual <lluis@ximian.com>
1904 * threads.c: Implemented SleepEx.
1905 * threads.h: Fixed SleepEx signature.
1907 2004-06-03 Miguel de Icaza <miguel@ximian.com>
1909 * threads.c: When running under valgrind, do not allocate too much
1910 stack, as Valgrind default is 1 meg.
1912 2004-05-27 Dick Porter <dick@ximian.com>
1915 * io.c: Implemented LockFile() and UnlockFile()
1917 2004-05-21 Dick Porter <dick@ximian.com>
1919 * io.c (CreateFile): Check for existing share modes when opening
1923 * handles-private.h:
1924 * daemon-messages.h:
1925 * daemon.c: Maintain a hash of file share modes, keying on device
1926 and inode (to cope with symlinks.)
1928 2004-05-20 Lluis Sanchez Gual <lluis@ximian.com>
1930 * daemon-messages.c: Retry if the communication with the daemon is
1931 interrupted by a signal.
1932 * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped.
1933 Only return an error in this case if there is something in the apc queue
1934 (which means that it is an interruption requested by the "user").
1935 * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as
1936 true since the wait is small.
1937 * shared.c: Retry write calls when interrumped by a signal.
1938 * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which
1939 returns TRUE if there are pending asynchronous calls (APC) for the
1940 provided thread. Also added _wapi_thread_dispatch_apc_queue which calls
1941 the enqueued APCs. Defined a new struct ApcInfo that holds information
1942 about an enqueued APC.
1943 * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same
1944 as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue.
1945 These last two methods call the corresponding apc methods in
1946 thread-private using the provided thread handle.
1947 * threads.h: Added QueueUserAPC.
1948 * uglify.h: Added WapiApcProc (needed by QueueUserAPC).
1949 * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and
1950 WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support
1951 for APCs in those two methods and also in SleepEx.
1953 2004-05-17 Dick Porter <dick@ximian.com>
1955 * io.c (CopyFile): Speed up. Fixes bug 57859.
1957 2004-05-13 Dick Porter <dick@ximian.com>
1958 * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current
1959 thread doesn't own the mutex, rather than assert()ing.
1961 2004-05-11 Dick Porter <dick@ximian.com>
1963 * shared.c (_wapi_shm_attach): Cope when a previous daemon startup
1964 attempt failed, leaving shared files that look like a daemon is
1967 2004-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1970 (SetFileAttributes): don't the the exec bit if the corresponding read
1973 2004-05-10 Zoltan Varga <vargaz@freemail.hu>
1975 * io.c (FindFirstFile): Fix invalid free.
1977 2004-05-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1979 * io.c: translate from GFileError to errno codes and don't free
1980 variables right after calling mono_io_scandir, as we may overwrite
1983 2004-05-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1985 * io.c: g_dir_open return ENOENT for directories on which we don't have
1986 read/execute permission, while returning EPERM for anything below those.
1987 So, change ENOENT by EPERM if the directory exists.
1989 2004-05-07 Dick Porter <dick@ximian.com>
1991 * io.c (SetFileAttributes): Don't have failed chmod()s cause a
1992 "file not found" error. Fixes bug 54032.
1994 2004-05-07 Dick Porter <dick@ximian.com>
1996 * io.c (FindFirstFile): Comment out a windows-compatibility check
1997 that breaks when directories have metachars in their names.
1998 Workaround for bug 58116.
2000 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2002 * io.c: fixed for FindFirstFile for empty directories. Closes
2005 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>

2010 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2012 * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
2013 * io.c: implemented scandir using glib functions.
2015 2004-05-04 Dick Porter <dick@ximian.com>
2017 * daemon.c (read_message): Return FALSE on error so the GSource
2018 callback itself can return FALSE. Cures the infinite loop poll()
2020 * shared.c: Fix some daemon startup race conditions.
2022 2004-04-29 Miguel de Icaza <miguel@ximian.com>
2024 * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k,
2025 use the stack, do not use dynamic memory.
2027 2004-04-29 Zoltan Varga <vargaz@freemail.hu>
2029 * io.c: Add scandir implementation for platforms which do not have
2032 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2034 * io.[ch]: implemented GetLogicalDriveStrings.
2036 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2039 * sockets.c: use the field name from configure when accessing sigval
2040 pointer field. Makes this work on the Mac.
2042 2004-04-28 Bernie Solomon <bernard@ugsolutions.com>
2044 * atomic.c: (InterlockedExchange) fix typo for
2047 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2050 * sockets.c: added check for sys/aio.h.
2052 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2054 * error.[ch]: added _wapi_get_win32_file_error...
2055 * io.c: ... which was _wapi_get_win32_error here.
2056 * sockets.c: rename the function calls here too.
2058 2004-04-28 Dick Porter <dick@ximian.com>
2060 * daemon-messages.c: Avoid a deadlock when a thread is killed while
2061 waiting for the daemon by using a recursive mutex. Helps bug 56699.
2063 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2065 * io.c: fixed leak in async_notifier().
2067 * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl
2070 * threads.c: removed old comment.
2072 2004-04-26 David Waite <mass@akuma.org>
2074 * daemon-messages.h:
2081 * wapi-private.h: remove comma from end of enumeration declarations
2082 * status.h: cast unsigned int types to int for enum assignment
2084 2004-04-26 David Waite <mass@akuma.org>
2087 * timefuncs.c: declare 64-bit constants as long long types (i.e.
2090 2004-04-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2092 * socket-wrappers.h: _wapi_socket == WSASocket now. Added
2093 WSA_FLAG_OVERLAPPED.
2095 * sockets.c: new unused parameters for _wapi_socket.
2097 2004-04-22 Miguel de Icaza <miguel@ximian.com>
2099 * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle
2100 the fact that MacOS X is a piece of junk (sem_init is *defined* in
2101 the libc, but they return `not implemented').
2103 2004-04-22 Dick Porter <dick@ximian.com>
2106 * handles-private.h: Reference the handle when it is locked, so
2107 that another thread can't blow it away while we're waiting for it
2108 to become signalled.
2119 * handles-private.h:
2122 * daemon-messages.c:
2123 * critical-sections.c:
2124 * atomic.c: Added pthreads cleanup handlers and error asserts
2127 * handles.c: Fixed the gcc "variable might be used uninitialised"
2128 warnings. They can't happen, but gcc doesn't know that
2129 g_assert()s don't return.
2131 Fixed the declaration of _wapi_handle_process_kill() so that it
2132 expects the correct type for the pid.
2134 * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that
2135 hasn't been used in ages and just made the code more complex.
2137 2004-04-17 Zoltan Varga <vargaz@freemail.hu>
2139 * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
2140 warnings. Fixes #57168.
2142 2004-04-16 Dick Porter <dick@ximian.com>
2144 * threads.c (Sleep): Using div(3) with a negative (when signed)
2145 numerator causes the quotient to be 0 and the remainder to be the
2146 numerator. This feeds a small negative value to nanosleep(3),
2147 which will return immediately and cause a busy wait. Fixes bug
2150 2004-04-15 Dick Porter <dick@ximian.com>
2153 * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3)
2154 and fnmatch(3) instead of glob(3). glob() can't cope with being
2155 given filenames containing metachars. This fixes bug 40557.
2157 2004-04-14 Bernie Solomon <bernard@ugsolutions.com>
2159 * security.c: #warning is a GCC-ism
2161 2004-04-13 Sebastien Pouliot <sebastien@ximian.com>
2163 * security.c: Removed GetUserName as glib g_get_user_name does a
2164 better (portability) job. Added ImpersonateLoggedOnUser and
2167 2004-04-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2169 * mono-mutex.h: move pthread_mutex_timedlock declaration to...
2170 * mono-mutex.c: ...here. It was causing a warning that prevented
2171 libgdiplus compilation.
2173 2004-04-04 Miguel de Icaza <miguel@ximian.com>
2175 * security.c (GetUserName): Make it work on MacOS X
2177 2004-04-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2179 * security.c: use getpwuid_r if available. This one is thread-safe.
2181 2004-04-02 Sebastien Pouliot <sebastien@ximian.com>
2183 * Makefile.am: Added security.c|h.
2184 * security.c: New file for security related functions. Added function
2185 GetUserName to fix #56144.
2186 * security.h: New. Header file for security.c
2187 * wapi.h: Added include for security.h
2189 2004-03-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2191 * daemon-messages.h: added kill structs.
2193 * daemon.c: implemented process_process_kill.
2194 * handles-private.h: define process_process_kill.
2195 * handles.c: implemented _wapi_handle_process_kill.
2196 * processes.[ch]: implemented TerminateProcess.
2198 2004-03-25 Bernie Solomon <bernard@ugsolutions.com>
2200 * daemon.c (rem_fd): On solaris you seem to get an
2201 error even after removing the input source so don't
2202 try and rem_fd it twice.
2204 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
2206 * daemon.c: in process_post_mortem, If the child terminated due to the
2207 receipt of a signal, the exit status must be based on WTERMSIG, since
2208 WEXITSTATUS returns 0 in this case.
2210 2004-03-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2212 * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.
2214 2004-03-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2216 * daemon.c: only call getdtablesize () once.
2217 * processes.c: wait 500 ms to check if execve failed and throw the same
2218 exception as MS on failure. Fixes bug #32809.
2220 2004-03-17 Bernie Solomon <bernard@ugsolutions.com>
2222 * io.c (async_notifier): use "union sigval" rather
2223 than sigval_t as Solaris doesn't have sigval_t
2224 (which isn't in IEEE 1003.1 either).
2226 2004-03-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2228 * io.c: added debug stuff and removed a few redundant lines in
2231 2004-03-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2233 * io-private.h: added new fields for file structure. Declare
2234 _wapi_io_add_callback.
2236 * io.c: added _wapi_get_win32_error, support aio_read/write in
2237 file_read/write. Implemented _wapi_io_add_callback, which is where
2240 * io.h: added new fields for WapiOverlapped and typedef for the
2243 * processes.c: fixed off-by-one bug when handling environment variables
2246 * threads.[ch]: implemented BindIoCompletionCallback.
2248 * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE.
2250 2004-03-14 Zoltan Varga <vargaz@freemail.hu>
2252 * socket-wrappers.h: Remove extra semicolon.
2254 2004-03-03 Dave Camp <dave@ximian.com>
2256 * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
2257 Use a new main context.
2259 2004-03-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2262 (GetFileAttributes): set the error depending on errno instead of
2263 setting ERROR_FILE_NOT_FOUND always. See bug #55160.
2265 2004-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2268 (CopyFile): free the buffer on error.
2270 (WSAIoctl): free the buffer on error.
2272 2004-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2274 * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT.
2276 * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW
2277 using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style.
2279 2004-01-27 Bernie Solomon <bernard@ugsolutions.com>
2281 * shared.c (_wapi_shm_file): add hostname
2282 to shared data file names to handle NFS mounted
2285 Mon Jan 26 16:15:03 CET 2004 Paolo Molaro <lupus@ximian.com>
2287 * sockets.h: remove obsolete soklen_t typedef.
2289 Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>
2291 * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket
2292 wrappers to its own non-installed header file.
2294 2004-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2297 (FindFirstFile): unlock the handle if FindNextFile fails.
2298 (FindNextFile): g_free a couple of pointers before retrying.
2301 (WaitForMultipleObjects): if only one handle provided, use
2302 WaitForSingleObject.
2304 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2306 * handles-private.h: (_wapi_handle_type) check
2307 for segment in range before using it
2309 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2311 * thread-private.h: _wapi_thread_ops is now const
2314 Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>
2316 * threads.c, timed-thread.c, timed-thread.h: use mach
2317 semaphores on Darwin (MacOSX) since the posix ones
2318 are mostly broken there (threads are not created suspended
2319 and they can start executing before they are fully initialized
2320 like in tests/thread-static.cs).
2322 Mon Dec 22 17:18:45 CET 2003 Paolo Molaro <lupus@ximian.com>
2324 * atomic.h: ppc fixes.
2326 2003-12-19 Bernie Solomon <bernard@ugsolutions.com>
2328 * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
2331 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2333 * shared.c: (_wapi_shm_open) make scratch file
2334 not have to immediately regrow to avoid remaps
2335 (HPUX can't cope with these).
2336 (_wapi_shm_attach) use actual size of file
2337 to set scratch data_len for the creating process.
2339 * handles.c: (_wapi_handle_new_internal) make
2340 sure mutex & cond var are initialized even for
2341 non process shared ones.
2342 (_wapi_handle_unref) always call destroy
2343 routines on mutex & cond var
2345 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2347 * daemon.c: change channel data structure so
2348 input sources are removed from glib event loop
2349 properly. xsp works better on Solaris and
2352 2003-12-12 Bernie Solomon <bernard@ugsolutions.com>
2354 * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
2355 definition with file & line number for non-GCC
2358 2003-12-08 Bernie Solomon <bernard@ugsolutions.com>
2360 * Makefile.am: make sure hppa_atomic.s is in distribution
2362 2003-12-01 Dick Porter <dick@ximian.com>
2365 * mutexes.c (CreateMutex):
2366 * mutex-private.h (struct _WapiHandle_mutex):
2367 * handles.c: Look up certain handle types by name, in a shared
2368 namespace. Currently only mutex handles have this implemented.
2371 * semaphores.c (CreateSemaphore):
2372 * events.c (CreateEvent): Fix signature
2374 2003-11-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2376 * io.c: don't call g_free before testing errno as it may modify it.
2377 If the path exists, return an error if it's not a directory. Fixes
2380 2003-11-20 Dick Porter <dick@ximian.com>
2382 * io.c: Missed a little-endian UTF16 conversion. Patch from
2383 Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.
2385 2003-10-29 Dick Porter <dick@ximian.com>
2387 * io.c (MoveFile): If the move crosses filesystems, try and fall
2388 back to copy and delete. Patch from Jörg Rosenkranz
2389 (JoergR@voelcker.com), fixes bug 50298.
2391 2003-10-28 Dick Porter <dick@ximian.com>
2393 * io.c: Use the new encoding conversion to cope with non-utf8
2394 locales in filenames.
2396 * processes.c: Ditto for process arguments.
2398 Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro <lupus@ximian.com>
2400 * atomic.h: some ppc inline asm fixes (incorrect use of labels,
2401 incorrect register constraints, incorrect clobber lists).
2403 2003-10-13 Bernie Solomon <bernard@ugsolutions.com>
2405 * Makefile.am hppa_atomic.s: add HP 64bit
2406 implementation of atomic ops
2408 2003-10-13 Zoltan Varga <vargaz@freemail.hu>
2410 * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
2411 a conditional for platforms that don't have it.
2413 2003-10-09 Bernie Solomon <bernard@ugsolutions.com>
2415 * threads.c: (CreateThread) use stacksize argument
2416 if non-zero - change default for 64 bits to 4Mb
2418 2003-09-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2420 * sockets.c: set last error when socket creation fails. This shed some
2421 light on bug #49015.
2423 2003-09-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2425 * processes.c: fixed bug #48973: we only change \ by / for the argument
2426 to be used as command.
2427 When getting the program name from the args, don't let the space between
2430 2003-09-24 Bernie Solomon <bernard@ugsolutions.com>
2432 * atomic.h atomic.c: fix sparc so lock is
2433 global, increment does so and it compiles under Sun compiler.
2435 2003-09-22 Bernie Solomon <bernard@ugsolutions.com>
2437 * handles.c: include <string.h> directly as may
2438 not be nested in <sys/un.h> like Linux
2440 2003-09-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2443 (DeleteFile): call SetLastError on failure. Fix by
2444 richard.torkar@htu.se (Richard Torkar). Closes bug #48222.
2446 2003-09-15 Lluis Sanchez Gual <lluis@ximian.com>
2448 * daemon.c: In compare_process(), discard handles already signalled.
2450 2003-09-02 Dick Porter <dick@ximian.com>
2452 * io.c: Work around glib brain-dead assumptions about utf8-encoded
2453 filenames. Fixes bug 30781.
2455 2003-08-28 Dick Porter <dick@ximian.com>
2457 * critical-sections.c: Patch from Bernie Solomon
2458 <bernard@ugsolutions.com> to emit a warning if locking a critical
2461 2003-07-23 Dick Porter <dick@ximian.com>
2464 * daemon.c (maybe_exit): Avoid the race condition when the daemon is
2465 closing but another client comes along when the shared data is still
2466 visible. Should fix bugs 33671 and 35213.
2468 2003-07-23 Dick Porter <dick@ximian.com>
2470 * handles.c: Initialise handle mutex and cond. Fix by
2471 Bernie Solomon <bernard@ugsolutions.com>
2473 2003-07-15 Dick Porter <dick@ximian.com>
2475 * timed-thread.c (timed_thread_start_routine): Fix virtual memory
2476 leak when threads quit. Fixes bug 44067.
2478 Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro <lupus@ximian.com>
2480 * io.c: never add write permission for group or others in
2481 SetFileAttributes ().
2483 2003-06-17 Dick Porter <dick@ximian.com>
2485 * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
2486 ignore the unsupported ones ("fixes" bug 44977).
2488 2003-06-17 Lluis Sanchez Gual <lluis@ximian.com>
2490 * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for
2491 high ms values (there was an overflow).
2493 2003-06-17 Zoltan Varga <vargaz@freemail.hu>
2495 * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.

2502 2003-06-10 Dick Porter <dick@ximian.com>
2504 * atomic.c: Delete the useless compile warning
2506 2003-06-09 Dick Porter <dick@ximian.com>
2508 * daemon.c: Lookup env as a string array. Fixes bug 44289. Also
2509 make setting the process handle value in the environment actually
2512 * processes.c: Pretty up the process name, if it happens to be
2513 "mono" such as when another mono process forks "mono foo.exe"
2515 2003-06-05 Dick Porter <dick@ximian.com>
2517 * processes.c (process_set_current): Don't do an expensive handle
2518 search at application startup, check the environment to see if the
2519 process handle has already been created.
2521 * io.c: Don't do an expensive handle search when creating stdin,
2522 stdout and stderr handles, just create them all the first time one
2529 * handles-private.h:
2530 * daemon-messages.h:
2532 * daemon.c: Support for "unlimited" number of handles and scratch
2535 Speed up application startup by passing process handle in the
2536 environment, rather than let the app scan all handles (which gets
2537 really slow when there are more than a few thousand to check.)
2539 Initialise some structs passed to syscalls, noticed by valgrind.
2542 2003-05-20 Dick Porter <dick@ximian.com>
2544 * io.c (FindFirstFile): Include . files in the glob. Fixes bug
2547 2003-05-19 Dick Porter <dick@ximian.com>
2549 * threads.c: Set the new thread's stack size to 2M. Fix needed
2550 for BSD, reported by Martin Dvorak <md@9ll.cz>
2552 2003-05-16 Dick Porter <dick@ximian.com>
2555 * io.c: Implement GetTempPath()
2557 2003-05-16 Dick Porter <dick@ximian.com>
2559 * processes.c (CreateProcess): Set some error codes
2561 2003-05-12 Dick Porter <dick@ximian.com>
2563 * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
2564 Patch from Martin Dvorak <mdvorak@ninell.cz>.
2566 2003-05-10 Dick Porter <dick@ximian.com>
2568 * io.c (CopyFile): Copy file mode as well as file data. Based on
2569 suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
2572 2003-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2574 * handles.c: don't call GC_gcollect when creating new handles.
2576 2003-05-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2578 * handles.c: added some debugging code. Call GC_gcollect
2579 before creating a new handle. It makes Lupus' test run smoother and
2580 faster (from 62 to 83 request per second). Notice that calling
2581 GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does
2582 not improve nor degrade the performance, so i don't do it.
2584 2003-05-02 Dick Porter <dick@ximian.com>
2586 * sockets.c: Rearrange closesocket() and socket_close_private(),
2587 and remember to unref the handle, so we don't leak socket handles.
2588 Fix from Pelle Johnsen <pelle.johnsen@mail.dk>
2590 2003-04-11 Dick Porter <dick@ximian.com>
2592 * atomic.h: ARM atomic operations by Malte Hildingson
2593 <tds00mahi@tellus.thn.htu.se>
2595 Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>
2597 * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.
2599 2003-04-03 Martin Baulig <martin@ximian.com>
2601 The following change is conditional to `WITH_INCLUDED_LIBGC'
2602 which is not yet enabled by default.
2604 * threads.c (SuspendThread, ResumeThread): Fully implemented this.
2605 (gc_init): New static function; install a signal handler for
2606 SIGPWR which is used to suspend threads. [FIXME: it SIGPWR
2607 doesn't exist on all Unix systems, we need to find another
2609 (mono_wapi_push_thread_stack): New public function. Tells the
2610 garbage collector about the current stack pointer of a suspended
2613 2003-04-03 Martin Baulig <martin@ximian.com>
2615 * timed-thread.h (TimedThread): Added `suspended_sem',
2616 `suspend_count' and `stack_ptr'.
2618 2003-03-28 Dick Porter <dick@ximian.com>
2620 * atomic.h: PPC support gratiously donated to the public domain
2621 by John Duncan <jddst19@mac.com>
2623 2003-03-20 Dick Porter <dick@ximian.com>
2625 * sockets.c (_wapi_connect): If connect() fails with EACCES, try
2626 setting SO_BROADCAST and connecting again. Fixes bug 39178.
2628 2003-03-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2630 * processes.c: included Jerome Laban's patch and call SetLastError when
2631 the executable is not found.
2633 2003-03-03 Dick Porter <dick@ximian.com>
2635 * io.c (CreateFile): Try opening directories readonly, so that
2636 timestamps can be adjusted. Patch by Elan Feingold
2637 <efeingold@mn.rr.com>.
2639 2003-02-25 Dick Porter <dick@ximian.com>
2641 * shared.c (_wapi_shm_attach): Return a failure code on system
2642 call errors, rather than exiting.
2644 2003-02-21 Dick Porter <dick@ximian.com>
2646 * processes.c (GetCurrentProcessId): Use the current process
2647 handle to return the process ID, as getpid() is unreliable
2648 (linuxthreads gives each thread a different pid). Fixes bug
2651 2003-02-21 Dick Porter <dick@ximian.com>
2653 * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug
2656 2003-02-11 Dick Porter <dick@ximian.com>
2659 * timefuncs.c: Added GetTickCount()
2661 2003-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2663 * error.c: added WSA_EHOSTUNREACH mapping.
2665 2003-01-26 Miguel de Icaza <miguel@ximian.com>
2667 * io.c (SetFileAttributes): This routine is not currently
2668 implemented for the general case, but I added a special case to
2669 set the executable bit on Linux.
2671 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
2673 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
2675 2003-01-08 Dick Porter <dick@ximian.com>
2677 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
2679 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
2681 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2682 Check for an implementation which says it supports
2683 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
2684 defines the symbol. Defined but with a value of -1 still
2685 means that it is unsupported.
2687 2002-12-08 Martin Baulig <martin@ximian.com>
2689 * handles.c (_wapi_handle_new): Create new non-shared handles with
2690 an initial refcount of 1, not 0.
2692 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
2694 * threads.c (TlsGetValue): removed unnecessary mutex
2696 2002-11-20 Dick Porter <dick@ximian.com>
2698 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
2699 need to store their data structure too.
2701 * threads.c: Make sure the threading data is initialised wherever
2704 2002-11-15 Dick Porter <dick@ximian.com>
2706 * timed-thread.c: Removed unneeded parameters in
2707 _wapi_timed_thread_attach().
2709 * threads.c: Renamed AttachThread() to make it not look like
2710 external API. Removed unneeded parameters.
2712 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2714 * error.[ch]: added errno_to_WSA (). It displays a warning and return
2715 WSASYSCALLFAILURE if there is no error mapping for the given errno,
2717 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
2719 2002-10-31 Dick Porter <dick@ximian.com>
2722 * io.c: Define and use INVALID_FILE_ATTRIBUTES
2724 2002-10-07 Dick Porter <dick@ximian.com>
2727 * daemon.c: Use a more accurate time source for process start and
2730 2002-10-03 Dick Porter <dick@ximian.com>
2734 * threads.c: Fixes for freebsd. Make sure that mutex and condition
2735 creation and deletion happen in the process that owns them, when
2736 POSIX shared thread objects aren't supported. This breaks on
2737 freebsd, as pthread_t is a pointer to data.
2739 2002-10-02 Dick Porter <dick@ximian.com>
2741 * shared.c: Use mmap() instead of sysv shm for the shared data.
2743 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
2747 * daemon.c: mmap()ed regions survive fork, so just pass the
2748 pointer to _wapi_daemon_main instead of mapping it again.
2750 2002-10-01 Dick Porter <dick@ximian.com>
2752 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
2753 Unfortunately libgc uses the same thread suspend technique that I
2754 want to, and the two don't mix: libgc will deadlock when it tries
2755 to stop the world if a thread has already been suspended by
2756 someone else. Just do the simple suspended create rather than the
2757 general purpose thread suspension for now.
2759 * threads.c: Pass create flags to the timed_thread create call, to
2760 implement suspended thread creation. ResumeThread() partially
2761 implemented, to cope with the case where a newly created but
2762 suspended thread is launched.
2764 2002-09-30 Dick Porter <dick@ximian.com>
2766 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
2769 2002-09-27 Dick Porter <dick@ximian.com>
2771 * semaphores.c: Only include semaphore.h if it's present. Patch
2772 for BSD from jmmv@hispabsd.org (Julio Merino).
2774 2002-09-27 Dick Porter <dick@ximian.com>
2776 * processes.c: Pass environment and working directory to the
2777 daemon when forking. Don't let argv[0] be duplicated when looking
2778 for the program name. Implement EnumProcessModules (simple
2779 version for now, lsof-style later if needed), GetModuleBaseName,
2780 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
2781 aren't available on Linux).
2783 * process-private.h: Store the process name, and the working set
2787 * handles-private.h: New functions to store and retrieve an array
2788 of strings in the scratch space
2790 * daemon.c: Don't miss deleting some handles when a client exits
2791 (we used to rely on the client doing the final cleanup, but
2792 obviously if the client is no longer there the daemon has to do
2795 Process forking now sets the environment and the working
2798 * io.c: Don't confuse fd 0 with an unassigned handle struct
2800 * atomic.h: Add a google cache alternative to the msdn URL
2802 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2805 (_wapi_recvfrom): added ECONNRESET to the switch.
2807 2002-09-24 Mark Crichton <crichton@gimp.org>
2809 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
2812 2002-09-19 Mark Crichton <crichton@gimp.org>
2814 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
2815 dont have Linux's abstract filesystem for sockets.
2817 2002-09-19 Mark Crichton <crichton@gimp.org>
2819 * atomic.h: Added SPARC atomic asm code.
2820 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2821 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
2822 Solaris 9, however, the code paths don't seem to work. More testing
2823 on the shared case is *really* needed.
2825 2002-09-03 Dick Porter <dick@ximian.com>
2828 * threads.c: Removed PosixKillThread(), because it's not in the
2831 2002-08-20 Dick Porter <dick@ximian.com>
2833 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
2834 multiples of 4 bytes, to keep header structures aligned. Needed
2835 for sparc, at least. (Patch from crichton@gimp.org)
2837 * handles.c: Removed 'disable_shm' variable (we've defaulted to
2838 building with shm enabled for months now)
2840 2002-08-19 Dick Porter <dick@ximian.com>
2842 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
2843 for legacy NeXT-based systems.
2845 2002-08-12 Dick Porter <dick@ximian.com>
2847 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
2848 from Joseph Wenninger <kde@jowenn.at>)
2850 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
2852 * threads.c: use fast spinlocks by default
2854 2002-08-02 Dick Porter <dick@ximian.com>
2856 * io.c (GetStdHandle): Add a handle reference when returning a
2857 duplicate console handle. This fixes the unref_handle errors in
2860 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
2862 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
2865 2002-08-01 Dick Porter <dick@ximian.com>
2867 * threads.c: Use atomic spinlocks in TLS functions
2870 * Makefile.am: Added mono-spinlock.h
2872 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
2874 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
2875 these are needed for sendmsg() and also for struct msghdr (at
2876 least on Solaris). Solaris still won't build because struct msghdr
2877 doesn't have msg_flags, msg_control, or msg_controllen members.
2878 (CMSG_SPACE): Define for systems that don't have it.
2881 2002-07-20 Dick Porter <dick@ximian.com>
2887 * handles.c: Implemented pipe handles
2890 * daemon.c: Fixed bug in handle closing.
2893 * daemon.c: Forked processes now close all open file descriptors.
2895 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
2897 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
2900 2002-07-19 Martin Baulig <martin@gnome.org>
2902 * threads.c (ExitThread): Call exit() if no threads has been
2905 2002-07-17 Dick Porter <dick@ximian.com>
2907 * daemon-messages.c: Freebsd fixes from Andreas Kohn
2908 <andreas.kohn@gmx.net>
2910 2002-07-15 Dick Porter <dick@ximian.com>
2912 * io.c: Removed bogus console_flush() method, that was just cut
2913 and pasted from file_flush when I separated the two handle types.
2915 2002-07-12 Dick Porter <dick@ximian.com>
2917 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
2918 flags. Fixes bug 27633.
2920 2002-07-12 Dick Porter <dick@ximian.com>
2924 * daemon.c: Use size of sockaddr_un.sun_path from config.h
2926 2002-07-12 Dick Porter <dick@ximian.com>
2928 * processes.c (CreateProcess): Send stdin, stdout and stderr
2929 handles if the startup info doesnt specify new ones
2931 * io.c (GetStdHandle): Return the same handle when the same
2932 standard handle is requested
2934 * handles.c: Pass file descriptors when forking
2936 * daemon.c: Use supplied file descriptors when forking a new
2939 * daemon-messages.h:
2940 * daemon-messages.c: Pass stdin, stdout and stderr file
2941 descriptors to the daemon (used when forking)
2943 2002-07-11 Miguel de Icaza <miguel@ximian.com>
2945 * daemon.c (_wapi_daemon_main): Use sizeof
2946 (main_socket_address.sun_path) instead of hardcoded 108 value.
2948 * handles.c (shared_init): Use sizeof
2949 (shared_socket_address.sun_path) instead of hardcoded 108 value.
2951 2002-07-10 Dennis Haney <davh@davh.dk>
2955 * daemon.c: Lots of documentation, some added error checking, and
2956 code readability improvements.
2958 * daemon-messages.h: Add the Error request type to improve error
2961 * daemon-messages.c: Do a bit more error checking on send() and
2962 recv(), and log errors with a higher severity level.
2964 2002-07-04 Dick Porter <dick@ximian.com>
2966 * daemon.c (process_process_fork): Fix argument handling, due to
2967 buggy understanding of g_strsplit() behaviour.
2969 2002-07-03 Dick Porter <dick@ximian.com>
2972 * threads.c: Implement OpenThread(). Define access-control values
2978 * Makefile.am: Added access.h, to hold shared access-control
2981 2002-07-02 Dick Porter <dick@ximian.com>
2983 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
2985 2002-07-02 Dick Porter <dick@ximian.com>
2987 * handles.c (shared_init): Make a second attempt to contact the
2988 daemon if the shared memory attach succeeds, but the connect()
2989 fails. (This copes with the daemon crashing without cleaning up
2995 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
2996 the daemon, it's now built into the library.
2998 2002-06-25 Dick Porter <dick@ximian.com>
3001 * handles-private.h:
3002 * daemon-messages.h:
3003 * daemon.c: Process forking and handle data management
3006 * process-private.h:
3007 * processes.c: Process forking and other support functions
3009 2002-06-25 Dick Porter <dick@ximian.com>
3011 * versioninfo.h: PE resource decoding
3013 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
3014 to be told the string length
3016 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
3017 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
3020 2002-06-12 Dick Porter <dick@ximian.com>
3023 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
3024 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
3025 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
3027 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
3029 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
3030 when writing to a closed socket.
3032 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
3034 * mono-mutex.c (mono_once): New convenience function for my
3039 * critical-sections.c:
3047 * atomic.c: Use mono_once() rather than pthread_once().
3049 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
3051 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
3052 if multiple threads all try to call _wapi_handle_new() before the
3053 shared data has been initialized, it is possible that we could get
3054 into a condition where shared_init() is being executed and later
3055 threads will pass by pthread_once() due to the fact that it has
3056 already been called and so therefor will attempt to use the shared
3057 data before it has been completely initialized. If we instead use
3058 a standard mutex locking mechanism around shared_init(), we can
3059 avoid the situation entirely. By wrapping the mutex locking in a
3060 check to see if we've already initialized the data, we can even
3061 avoid wasting resources by having to lock/unlock the mutex in any
3062 later calls (the only time we'd have to worry about
3063 locking/unlocking is the initial race to call shared_init() at
3066 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
3068 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
3070 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
3072 * daemon.c, handles.c: rename "sun" local var since it's apparently
3073 a #define on Solaris.
3075 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
3077 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
3080 2002-05-15 Dick Porter <dick@ximian.com>
3082 * wait.c: Fix a deadlock in WaitForMultipleObjects
3084 2002-05-14 Dick Porter <dick@ximian.com>
3086 * io.c: Fix a cut&paste error, found by
3087 Jaroslaw Kowalski <jarek@atm.com.pl>
3089 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
3093 2002-05-09 Dick Porter <dick@ximian.com>
3099 * handles-private.h:
3101 * Makefile.am: Remove now-unused file wait-private.h
3103 2002-05-08 Dick Porter <dick@ximian.com>
3105 * shared.c: Better error messages, and report when daemon
3106 connection fails rather than blocking forever. Do some more
3107 shared memory sanity checking.
3109 * handles.c: Better error messages when connecting to shared
3110 memory and the handle daemon. Fall back to non-shared handles if
3111 an error occurs. Set the default back to 'shared handles'. Fix a
3112 crashing bug in scratch space allocation that mangled the block
3115 2002-05-07 Miguel de Icaza <miguel@ximian.com>
3117 * handles.c (shared_init): Disable SHM for now, people have too
3118 many problems with this, and the diagnostics are not helping.
3120 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
3122 * io.c: CreateFile sets win32 last error.
3124 2002-05-05 Dick Porter <dick@ximian.com>
3127 * handles-private.h:
3133 * process-private.h:
3135 * semaphore-private.h:
3139 * event-private.h: Simplify the WapiHandleOps struct: take out all
3140 the file-specific entries, leaving just the items that operate on
3141 handles themselves. Split the close operation into shared and
3142 private parts: shared close is called by the daemon.
3144 * handles.c: As above, but also pass handle allocation, ref and
3145 unref operations to the daemon. Populate the handle_ops array at
3146 compile time, because the daemon needs to call ops on handles too.
3147 Don't bother to track open handle counts any more, the daemon does
3151 * thread-private.h: As above, but also make the thread data
3154 * shared.c: Fork a handle daemon if the calling process created
3155 the shared memory segment.
3158 * daemon-messages.c:
3159 * daemon-messages.h:
3160 * Makefile.am: Build a daemon to manage handle allocation and
3161 destruction without needing to lock the shared memory
3163 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
3165 * atomic.c: Changed to use a normal mutex rather than a spinlock
3166 since a lot of platforms seem to not have them :\
3168 2002-04-30 Dick Porter <dick@ximian.com>
3170 * Completely rewrote the handle waiting code: removed the helper
3171 thread and its attendant complexity. All handle waiting is now
3172 abstracted into the WaitForSingleObject() and
3173 WaitForMultipleObjects() functions.
3175 * Implemented inter-process sharing of handles using sysv shared
3176 memory. This makes handles even more opaque, with a handle now
3177 just an index into an array.
3179 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>

3265 2002-03-22 Dick Porter <dick@ximian.com>
3267 * threads.c: Fix a race condition where a thread can start and
3268 exit before the handle has been properly initialised (no reason
3269 why the handle couldn't be initialised beforehand, so do so)

3273 2002-03-21 Dick Porter <dick@ximian.com>
3275 * semaphores.c: Fix a problem when waiting for one or more
