61 2008-05-25 Zoltan Varga <vargaz@gmail.com>
63 * thread-private.h (struct _WapiHandle_thread): Remove 'owner_pid' field. Reorder

68 restrictions on its usage.
70 2008-05-14 Zoltan Varga <vargaz@gmail.com>

104 * wapi_glob.c (globextend): Comment out the code using ARG_MAX, as
105 that is broken on the latest opensuse.
107 2008-04-21 Dick Porter <dick@ximian.com>
109 * io.c (DeleteFile): Disable for now the bug fix for 323389, it's
110 breaking too much other stuff.

136 2008-04-08 Dick Porter <dick@ximian.com>
138 * processes.c (CreateProcess): Improve the managed binary support,
139 so it works when the executable is passed in as the appname.

173 2008-03-28 Dick Porter <dick@ximian.com>
175 * processes.c (GetExitCodeProcess): Check if a process has exited

177 signalled. Fixes bug 325463.
179 2008-03-27 Dick Porter <dick@ximian.com>
181 * processes.c (match_procname_to_modulename): Check the whole

187 * processes.c (ShellExecuteEx): Grotty kludge to work around
188 unpleasant feature in g_shell_parse_argv() where it treats '#'
189 embedded in a filename as a comment marker, and throws away the
190 rest of the line. When we're directly opening URLs quote the
191 filename, to avoid this. Fixes bug 371567.
193 2008-03-25 Dick Porter <dick@ximian.com>
195 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment file layout

205 GetProcessId unconditionally.
207 2008-03-20 Kornél Pál <kornelpal@gmail.com>
209 * io-layer.h: Removed Windows version macros.
211 Thu Mar 13 16:24:53 CET 2008 Paolo Molaro <lupus@ximian.com>

220 * processes.c (match_procname_to_modulename) : Added to check if the last
221 part of module name is equal to the process name.
223 * processes.c (EnumProcessModules) : Changed the first entry in the returned
224 modules array (the process module) to be populated from the entry found
227 * processes.c (get_module_name & GetModuleInformation) : In the case where
228 the module passed in is NULL, search the /proc/<PID>/maps for a name that
229 matches the process name to populate the return information.
233 2008-01-29 Zoltan Varga <vargaz@gmail.com>
235 * security.c (RevertToSelf): Make this return TRUE if impersonating is not
238 * sockets.c (_wapi_connect): Add a workaround to a solaris x86 problem where

251 block is first in the resources data, and we just need to step
252 over it. Fixes bug 354856.
254 2008-01-16 Dick Porter <dick@ximian.com>
256 * threads.c (_wapi_thread_set_termination_details): Move the
257 thread abandonment to outside the shared handle lock. Fixes bug
260 2008-01-16 Dick Porter <dick@ximian.com>

263 string length, for MS compatibility.
265 2008-01-09 Dick Porter <dick@ximian.com>
267 * versioninfo.c (get_ptr_from_rva, scan_resource_dir): Make it
268 work on big-endian systems.
269 (scan_resource_dir): Copy the resource directory entry and
270 byteswap if necessary so it works big-endian. This fixes bug
271 345972 for real this time.
272 (VerQueryValue): String values set the length to the number of
273 unicode chars, but the data length reported was already correct so
274 don't halve it again. Fixes the previous fix for bug 345972.
275 (GetFileVersionInfo): On big-endian systems, scan the resource
276 data and turn all unicode strings into UTF-16BE. FileVersionInfo
277 now works big-endian.
279 2008-01-04 Dick Porter <dick@ximian.com>
281 * versioninfo.c (VerQueryValue): Returned buffer length counts
282 chars not bytes for string data. Fixes bug 345972 again.
283 (get_enclosing_section_header): Make sure values read are treated
284 as LE. Fixes crash on ppc reported in bug 345972.
286 2007-12-17 Mark Probst <mark.probst@gmail.com>
288 * threads.c: Guard against a race condition involving
289 thread_hash_key that can occur during shutdown.

328 (EnumProcessModules): Don't miss the first module returned by
331 2007-11-15 Dick Porter <dick@ximian.com>
333 * processes.c: Implement process module support by reading from
334 /proc if it's available.

343 section asserts for the release branch
345 2007-11-05 Kornél Pál <kornelpal@gmail.com>
347 * io-layer.h: Added includes for run-time GetProcessId API detection for
350 2007-10-26 Dick Porter <dick@ximian.com>
352 * shared.c (_wapi_shm_file_open): Set the umask when opening
353 shared files, so restrictive defaults don't prevent subsequent
354 processes re-opening them.
356 2007-10-18 Zoltan Varga <vargaz@gmail.com>
358 * atomic.h (InterlockedCompareExchange): Fix the ia64 version so it works for

363 * io-portability.c (_wapi_io_scandir): Only update the error
364 status of glob() when performing a secondary glob() if the first
365 returned an error. Fixes bug 325107.
367 2007-09-12 Marek Habersack <mhabersack@novell.com>
369 * io-portability.c: options_init moved to
370 utils/mono-io-portability.c
371 Do not initialize portability helpers here, it's done in
373 find_file and find_in_dir moved to utils/mono-io-portability.c

397 2007-09-03 Atsushi Enomoto <atsushi@ximian.com>
399 * processes.c, processes.h: added CreateProcessWithLogonW(). For now
400 it just calls CreateProcess().
401 * io-layer.h : CreateProcessWithLogonW() requires WINVER 0x0500
404 2007-08-23 Robert Jordan <robertj@gmx.net>
406 * processes.[c|h]: Implement Get|SetPriorityClass ().

493 * atomic.h: Enable for all hppa targets.
494 * Makefile.am: rename hppa_atomic.s to hppa_atomic.S so the preprocessor
496 * hppa_atomic.s: Renamed to ...
497 * hppa_atomic.S: ... and updated to work on both HPUX and Linux.
499 2007-06-13 Dick Porter <dick@ximian.com>
501 * handles.c (timedwait_signal_wait_cond): Alertable waits on
502 private handles are now interrupted by signalling the same
503 condition that would end the wait if the handle became signalled,
504 rather than polling. (Shared handles still have to poll.)
506 * threads.c (_wapi_thread_queue_apc): Interrupt the thread if it's
509 * handles-private.h (_wapi_handle_current_thread_set_waiting_on):
510 Helper functions to inform the APC queuing functions when threads

525 2007-05-21 Dick Porter <dick@ximian.com>
527 * io-portability.c (_wapi_g_dir_open): Don't propagate any errors
528 from the second call to g_dir_open, preserve the original error if
529 the second call still fails but clear the error if it succeeds.
531 2007-05-10 Dick Porter <dick@ximian.com>
533 * sockets.c (_wapi_recvfrom): Refine the fix to bug 75705 so EINTR
534 isn't returned if the remote end shuts down cleanly. Fixes zmd
535 and the second example in bug 75705.
537 2007-04-26 Dick Porter <dick@ximian.com>
539 * shared.c (_wapi_shm_semaphores_init): Need to check

552 * shared.c: Complete the reimplementation of disabling of shared
553 memory, by not allocating sysv semaphores when shm disabling has
554 been requested (either at compile time or run time.)
556 * processes.c (CreateProcess): Don't synchronize locking across

570 extended to match with case-insensitivity if needed.
573 * wapi_glob.c: Cut down implementation of glob(3), based on
576 2007-03-22 Dick Porter <dick@ximian.com>
578 * sockets.c (_wapi_connect): Do additional checks when connect(2)

597 and s390x ( bnc #237611 and bxc #80892 )
599 2007-03-05 Miguel de Icaza <miguel@novell.com>
601 * io.c (CreateFile): Use FILE_ATTRIBUTE_TEMPORARY to mean 0600
602 permissions. For 80688
604 (MoveFile): Use errno_copy here, just to avoid a potential
605 errno-changing code in the future from g_free.
607 Also, ignore EXDEV errors as they are handled immediately after
608 (avoid printing out an error).
612 Mon Feb 12 15:50:24 CET 2007 Paolo Molaro <lupus@ximian.com>
614 * shared.c: exit if semaphores can't be created (bug #80616).
616 2007-02-01 Geoff Norton <gnorton@customerdna.com>

630 * atomic.h: add locking primitives for MIPS.
632 2007-01-11 Dick Porter <dick@ximian.com>
634 * sockets.c (_wapi_connect): Don't do the SO_BROADCAST setting
635 here, do it in managed code instead.
636 (_wapi_getsockopt): SO_RCVTIMEO and SO_SNDTIMEO use struct
637 timeval, which has a microsecond field, not milliseconds.
638 (_wapi_setsockopt): ditto.
639 (_wapi_setsockopt): Halve the SO_SNDBUF and SO_RCVBUF values on
640 Linux, as the kernel doubles whatever we set.
641 (_wapi_socket): Save socket domain, type and protocol so it can be
643 (socket_disconnect): Implement socket disconnect (closing the
644 socket, but keeping the file descriptor.)
645 (wapi_disconnectex): A basic implementation of DisconnectEx().
646 (wapi_transmitfile): A very basic implementation of
648 (WSAIoctl): Implement the SIO_GET_EXTENSION_FUNCTION_POINTER
651 * socket-private.h (struct _WapiHandle_socket): Record socket
652 domain, type and protocol info so it can be duplicated later.
654 * sockets.h (WSAID_DISCONNECTEX,WSAID_TRANSMITFILE): Structures
655 and defines needed to look up the DisconnectEx() and
656 TransmitFile() functions by GUID.
658 * error.c (errno_to_WSA): Change ETIMEDOUT mapping to
659 WSAETIMEDOUT; add EDESTADDRREQ.
661 * io-layer.h: Need mswsock.h on windows now.
663 2007-01-04 Miguel de Icaza <miguel@novell.com>
665 * io-portability.c (find_file): Fix a coverity warning (scanning
668 2006-12-31 Miguel de Icaza <miguel@novell.com>
670 * io-portability.c (find_file): Do not abort if an empty filename
671 has been passed. This fixes the case where MONO_IOMAP=all would
672 assert if Directory.Exists ("") was called.
674 Mon Dec 18 14:54:37 CET 2006 Paolo Molaro <lupus@ximian.com>
676 * processes.c: moved a free on the error path.
678 Thu Dec 14 21:42:39 CET 2006 Paolo Molaro <lupus@ximian.com>
680 * processes.c: fixed a few memory leaks when executing
683 Mon Nov 27 13:12:17 GMT 2006 Paolo Molaro <lupus@ximian.com>
685 * atomic.h: fix arm compare and exchange (bug #78500).
687 2006-11-23 Dick Porter <dick@ximian.com>
689 * process-private.h (struct _WapiHandle_process): Add 'waited'
692 * processes.c (process_wait): Check the 'waited' parameter not the
693 signalled state when testing if a process has already been waited
694 for, as the child process itself may set signalled when exiting.
697 * wapi-private.h (_WAPI_HANDLE_VERSION): Bump shared data version
699 * shared.c: Now the shared data version has been incremented we
700 can set the counter semaphore initial value correctly
702 2006-11-22 Dick Porter <dick@ximian.com>
704 * processes.c (process_wait): Cope when the background process
705 reaper gets the process we were waiting for. Special case for
706 waiting for our own process to exit. Fixes bug 77736.
708 2006-11-17 Dick Porter <dick@ximian.com>
710 * processes.c: Fix const correctness and typos that caused memory
713 2006-11-17 Miguel de Icaza <miguel@novell.com>
715 * processes.c (ShellExecuteEx): Check error after CreateProcess,
716 thanks to Dick for pointing this out.
718 2006-11-16 Miguel de Icaza <miguel@novell.com>
720 * processes.c (ShellExecuteEx): If we fail to create a process in
721 ShellExecute, then try to use the xdg-open command, and if that
722 fails, try to use the gnome-open command,
724 Refactor the code so that we do not have to duplicate all this
725 code, but instead use a ucs2-aware version of the code to do
728 2006-11-13 Dick Porter <dick@ximian.com>
730 * io.c (_wapi_stat_to_file_attributes): If the file is a symlink
731 add the FILE_ATTRIBUTE_REPARSE_POINT flag. This is an attempt to
732 follow the specs for the windows symlink support, but will
733 probably have to be reworked when I have test data from a vista
734 machine. Fixes bug 79887.
736 2006-11-11 Miguel de Icaza <miguel@novell.com>
738 * handles.c (CloseHandle): Cope here with the new value
739 INVALID_HANDLE_VALUE set on handles.
741 * processes.c (CreateProcess): Initialize the value of hThread to
742 be INVALID_HANDLE_VALUE on failure, not to be NULL. Improvement
745 2006-11-09 Dick Porter <dick@ximian.com>
747 * sockets.c (_wapi_select): Do some sanity checking on the
748 fd_sets, to avoid file descriptors > FD_SETSIZE.
749 (_wapi_FD_CLR, _wapi_FD_ISSET, _wapi_FD_SET): Avoid file
750 descriptors > FD_SETSIZE.
752 2006-10-27 Dick Porter <dick@ximian.com>
754 * io.c (GetFileAttributes): Force symlinks to directories to be
755 returned as a regular file. Fixes bug 79733.
757 2006-10-18 Miguel de Icaza <miguel@novell.com>
759 * io-portability.c (find_in_dir): First string dup, then closedir.
761 2006-10-12 Dick Porter <dick@ximian.com>
763 * processes.c (_wapi_process_reap): Unref a process handle if we
764 reaped it, found by Zoltan. Fixes bug 79286.
765 (process_wait): Don't wait again if we've already waited for a
768 2006-10-11 Sergey Tikhonov <tsv@solvo.ru>
770 * atomic.h: Fix atomic decrement.
772 * mini/cpu-alpha.md: Use native long shift insts
774 * mono/mono/mini/tramp-alpha.c: Implemented
775 mono_arch_patch_delegate_trampoline method
777 * Started work on using global registers
779 * Use byte/word memory load/store insts if cpu supports it
784 2006-10-09 Zoltan Varga <vargaz@gmail.com>
786 * handles.c (timedwait_signal_poll_cond): Add an alertable parameter, and if it
787 is FALSE, avoid busy waiting.
789 * wait.c: Add an alertable parameter to the wait routines.
791 2006-10-06 Miguel de Icaza <miguel@novell.com>
793 * io-portability.c (find_file): Rename from
794 MONO_IO_PORTABILITY_HELP to MONO_IOMAP.
796 2006-10-03 Dick Porter <dick@ximian.com>
799 * io-portability.c: Optional portability helpers and wrapped
800 system calls to try to cope with windows filenames in
803 * io.c: Use the wrapped system calls
805 2006-09-01 Zoltan Varga <vargaz@gmail.com>
807 * critical-sections.h critical-sections.c: Make Enter/LeaveCriticalSection a macro
808 since they are perf critical.
810 * atomic.h: Applied patch from Jakub Boqusz <qboosh@pld-linux.org>.
811 Add atomic ops implementation for alpha.
813 2006-08-11 Dick Porter <dick@ximian.com>
815 * processes.c (_wapi_process_reap): Avoid a deadlock by setting
816 process termination details in an outer loop, not the
817 _wapi_search_handle() one.
819 2006-08-10 Dick Porter <dick@ximian.com>
821 * threads.c (_wapi_thread_queue_apc)
822 (_wapi_thread_dispatch_apc_queue): Use a process-local mutex here
823 instead of the cross process semaphore. We already check that
824 access to the APC queue is within the owning process so there's no
825 need to protect from other processes. Avoids a global deadlock
826 when a thread is aborted while it holds the handle semaphore
828 (_wapi_thread_apc_pending): Hide an annoying message which can
829 happen if a thread handle has been blown away at process shutdown
830 while it is in an alertable wait.
832 Both problems seen while shutting down monodevelop.
834 2006-07-25 Dick Porter <dick@ximian.com>
836 * shared.c (_wapi_shm_file): Remove '/' characters from the uname
837 results. Fixes bug 78917.
839 2006-07-20 Dick Porter <dick@ximian.com>
841 * threads.c (_wapi_thread_set_termination_details): Improve the
842 test for already-disposed thread handles, and hold the lock around
843 the mutex abandoning.
845 2006-07-17 Dick Porter <dick@ximian.com>
847 * processes.c (CreateProcess): Don't change directory unless a new
848 one has been specified. Fixes bug 78751.
850 2006-07-06 Dick Porter <dick@ximian.com>
852 * io.c (_wapi_stat_to_file_attributes): Do a better job at
853 figuring out the file attributes
854 (_wapi_set_last_path_error_from_errno): New helper function to
855 turn errno into w32 error codes that handles the differences
856 between file and directory errors
857 (file_setendoffile): Try turning off the extra write used to
858 extend files, because we probably don't need it on any modern
859 platform. If it is needed though, we also need to lseek the file
861 (CreateFile): Treat character-special devices as a console handle,
862 because they can't be seeked
863 (CopyFile): If fail_if_exists is set, then the destination needs
864 to be opened with O_EXCL
865 (CopyFile): If fail_if_exists is not set and the destination
866 already exists, then we should set the ERROR_ALREADY_EXISTS error
867 even though we return success
868 (stdhandle_create): STD_INPUT_HANDLES cannot be written to
869 (GetStdHandle): Rework without using mono_once, so console handles
870 can be properly closed and reopened.
871 (mono_io_scandir): Only override errno with EACCES when the
872 directory actually exists
873 (FindFirstFile): Set ERROR_FILE_NOT_FOUND when no files are
875 (FindClose): Cope with NULL handles
876 (CreateDirectory): When the target already exists, just return an
877 error. It's the caller's job to figure out what to do.
878 (SetCurrentDirectory): Cope with a NULL path
879 (RemoveDirectory, GetFileAttributes, GetFileAttributesEx,
880 SetFileAttributes, FindFirstFile, DeleteFile, MoveFile, CopyFile,
881 CreateFile): Set path error correctly
883 * handles.c (CloseHandle): Kludge to try and cope with passing a
886 * error.h: Add NO_ERROR as an alternative to ERROR_SUCCESS
888 * uglify.h: Added some more typedefs
890 2006-07-05 Dick Porter <dick@ximian.com>
892 * io.c (GetFileAttributes, GetFileAttributesEx): Cope with
893 dangling symlinks. Fixes bug 78664.
895 2006-06-23 Dick Porter <dick@ximian.com>
897 * handles.c (handle_cleanup):
898 * threads.c: Clean up threads properly when we're forcibly
899 removing the handle entries from the shared file in
900 handle_cleanup(). Fixes bug 78241, for real this time.
902 2006-06-15 Neale Ferguson <neale@sinenomine.net>
904 * atomic.h: More tinkering with InterlockedExchange/InterlockedCompareExchange
907 2006-06-14 Neale Ferguson <neale@sinenomine.net>
909 * atomic.h: Fix atomic exchange pointer operations for s390x - these
910 were broken as they used 32-bit instructions rather than their 64-bit
913 2006-06-14 Dick Porter <dick@ximian.com>
915 * processes.c: Don't run the atexit handlers when bailing out
918 2006-06-14 Dick Porter <dick@ximian.com>
920 * wait.c: Fix stupid typo shown up by gcc 4.1.1, = not ==
928 * collection.c: Fix a bunch of signed/unsigned warnings from gcc
931 2006-06-09 Neale Ferguson <neale@sinenomine.net>
933 * atomic.h: Fix atomic operations for s390x (not really broken
934 but changed to use full 64-bit opcodes).
936 2006-05-24 Dick Porter <dick@ximian.com>
938 * processes.c (process_set_current): Don't take an extra reference
939 if we have to create our own process handle. Fixes bug 78241
942 * threads.c (_wapi_thread_signal_self): Renamed from
943 _wapi_thread_abandon_mutexes, also sets the thread state to
944 signalled and drops a reference. Called by the runtime when the
945 main thread cleans itself up.
947 * handles.c (handle_cleanup): As a last resort, unref every shared
948 handle as the process is now exiting.
950 2006-05-16 Dick Porter <dick@ximian.com>
952 * processes.c (process_set_termination_details): Unref the handle
953 when we've stored the exit details. Fixes the rest of 78241.
955 2006-05-12 Dick Porter <dick@ximian.com>
957 * threads.c: Implement pseudo handles, making GetCurrentThread()
958 match MS behaviour. Notice when attached threads exit, and unref
959 the handle. Fix usage of GetCurrentThread() in other places.
961 * handles.c (DuplicateHandle): Implement a basic form of
964 * wait.c: Fix usage of GetCurrentThread() throughout, and cope
967 2006-04-26 Miguel de Icaza <miguel@novell.com>
969 * io.c (file_close): Oops, do not use DeleteFile which expects
970 unicode, instead use unlink directly
972 Add support for the new FileOptions bits on .NET 2.0.
974 It might be good if Dick reviews these changes.
976 * io.c (file_close): If DeleteOnClose is set, then delete the file
978 (CreateFile): Do not support encryption per user.
980 If posix_fadvise exists, pass hints on sequential scan and random
981 access. Did not figure out what WRITE_THROUGH maps to.
983 2006-04-26 Dick Porter <dick@ximian.com>
985 * sockets.c (WSAIoctl): Check the output buffer is valid before
988 * handles.c (_wapi_search_handle): Set shared pointer if we find a
989 shared handle that has been already opened.
991 2006-04-21 Dick Porter <dick@ximian.com>
993 * threads.c (GetCurrentThread): Reference the handle if we return
994 an already-known thread.
996 2006-04-07 Dick Porter <dick@ximian.com>
998 * processes.c: Fix build for older glib.
1000 2006-04-06 Dick Porter <dick@ximian.com>
1002 * processes.c (CreateProcess): Add a reference to the child
1003 process' handle, so it won't be destroyed if this process closes
1004 its copy of the handle. Fixes bug 77393.
1006 * processes.c (process_set_current): Fall through to creating a
1007 new one if the handle lookup fails.
1009 * processes.c (_wapi_process_signal_self):
1010 * handles.c (handle_cleanup): The process is exiting, so set the
1011 handle state for this process to signalled. This should let other
1012 non-related processes wait for this handle.
1014 * handles.c (_wapi_search_handle): Don't search shared handles in
1017 * collection.c (collection_thread): No need to do a collection
1018 scan straight away, do the waiting first.
1020 2006-04-06 Dick Porter <dick@ximian.com>
1022 * shared.c: Fix parameters in semctl () call.
1024 2006-03-28 Zoltan Varga <vargaz@gmail.com>
1026 * atomic.h atomic.c: Applied patch from David S. Miller
1027 <davem@davemloft.net>: Reimplement Interlocked* primitives on sparc
1028 using CAS/CASx when __GNUC__, else we will fall back to the generic
1031 2006-03-27 Dick Porter <dick@ximian.com>
1033 * shared.c (_wapi_shm_file_open): Break out of a loop if the
1034 shared file is smaller than expected. (We loop a few times in
1035 case another process is in the middle of creating the file.)
1037 2006-03-22 Dick Porter <dick@ximian.com>
1042 * shared.c: Delete the semaphores and shared files when the last
1043 process has finished with them
1045 2006-03-15 Dick Porter <dick@ximian.com>
1053 * threads.c: Explicitly initialise the handle ops struct
1055 2006-03-14 Dick Porter <dick@ximian.com>
1057 * handles-private.h:
1060 * handles.c: Add a 'prewait' stage to the handle waiting, to give
1061 waiting threads a chance to check for bogus states before
1064 * mutexes.c (namedmutex_prewait): Use the prewait stage to check
1065 for named mutexes that have been abandoned in a locked state (eg
1066 if a process exited abnormally while owning the mutex) and
1067 override it if needed.
1069 2006-03-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1071 * wait.c: speed up WaitFor* when the timeout is 0.
1073 2006-03-03 Dick Porter <dick@ximian.com>
1075 * processes.c (ShellExecuteEx): Cope when some of the parameters
1078 2006-02-27 Dick Porter <dick@ximian.com>
1082 * threads.c: Comparing pthread_t with == is not portable, so use
1085 Thu Feb 23 18:47:20 GMT 2006 Paolo Molaro <lupus@ximian.com>
1087 * *.h, *.h: patch from Dick to make Linuxthreads systems work again.
1089 2006-02-22 Dick Porter <dick@ximian.com>
1092 * threads.c: There's no need to use the timed-thread support code
1093 any more, as we aren't using the timed join. This greatly
1094 simplifies thread setup, and fixes a memory leak (bug 77521).
1096 Don't bother to store thread IDs in a hash table, use TLS instead.
1097 The one case that needs to look up the handle of a different
1098 thread (OpenThread()) can do the extra work itself. Fixes bug
1101 * handles.c (_wapi_search_handle): Add a reference when returning
1102 a private handle (shared handles are already reffed.)
1104 2006-02-17 Dick Porter <dick@ximian.com>
1106 * handles-private.h:
1107 * handles.c: Check handle values passed to array lookups. Fixes
1110 2006-02-09 Dick Porter <dick@ximian.com>
1112 * threads.c: Cope with the problems caused by attaching already
1113 existing threads - they don't get the infrastructure to clean up
1114 after themselves, especially the ID to handle hash. This fixes
1117 2006-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1119 * shared.c: use MONO_SHARED_HOSTNAME as a substitute for gethostname()
1120 when creating the shared files in the .wapi directory. Fixes bug #77371.
1122 2006-02-02 Martin Baulig <martin@ximian.com>
1124 * threads.c: Removed the `WITH_INCLUDED_LIBGC' section; it has
1125 never been used so far.
1127 * timed-thread.h (TimedThread): Removed the `stack_ptr' field; it
1128 has only been used by the removed code.
1130 2006-01-03 Neale Ferguson <neale@sinenomine.net>
1132 * atomic.h: Correct s390x definitions and eliminate compiler warnings.
1134 2006-01-03 Sebastien Pouliot <sebastien@ximian.com>
1136 * io.c: Patch _wapi_stat_to_file_attributes against bug #76966, where
1137 sockets could be considered as directory.
1139 2005-12-23 Dick Porter <dick@ximian.com>
1143 * semaphores.c: Implement OpenSemaphore
1146 * mutexes.h: Implement OpenMutex
1152 * event-private.h: Implement named events. Implement OpenEvent.
1154 2005-12-15 Dick Porter <dick@ximian.com>
1156 * processes.c (CreateProcess): The pipe-based cross-process
1157 exclusion technique was trying to write NULL buffers when appname
1158 was NULL (eg when coming from ShellExecuteEx,) which usually
1159 succeeded even though EFAULT was returned - but sometimes it
1160 failed. This meant that the child process could block forever on
1161 the pipe read. Replace it with the simpler shared handle
1162 semaphore protection used everywhere else. This showed up with
1163 the test case in bug 76684.
1165 Tue Dec 13 11:41:49 GMT 2005 Paolo Molaro <lupus@ximian.com>
1167 * shared.c: fallback to private mmap when shared mmap doesn't work
1170 2005-12-06 Dick Porter <dick@ximian.com>
1174 * semaphore-private.h:
1175 * semaphores.c: Implement named semaphores
1177 2005-11-24 Dick Porter <dick@ximian.com>
1179 * processes.c (GetProcessId): Implement GetProcessId()
1181 2005-11-17 Dick Porter <dick@ximian.com>
1184 * processes.c: Implement ShellExecuteEx as a wrapper around
1187 2005-11-11 Dick Porter <dick@ximian.com>
1189 * threads.c: Give mutex abandoning its own exported function, so
1190 it can be called when the runtime is cleaning up.
1192 * handles.c (_wapi_search_handle_namespace): Do a handle
1193 collection befre starting to check namespace strings, so that any
1194 stale cruft gets removed.
1196 2005-11-11 Dick Porter <dick@ximian.com>
1198 * threads.c: Move thread handles back into the shared space.
1200 * handles.c (_wapi_handle_unref): Add support for shared handles
1201 with close() handlers
1203 2005-11-04 Dick Porter <dick@ximian.com>
1205 * sockets.c (ioctlsocket): Use select instead of if to avoid a
1206 type promotion problem on 64bit freebsd. Based on patch by Lou
1207 Kamenov <kamenovl@gmail.com>, fixes bug 76447.
1209 2005-11-04 Dick Porter <dick@ximian.com>
1211 * io.c (file_write): Only do the file locking if
1212 MONO_STRICT_IO_EMULATION is set.
1214 2005-10-21 Dick Porter <dick@ximian.com>
1217 * handles.c (_wapi_lookup_handle): Cope when the shared part of a
1218 handle has been deleted.
1219 (_wapi_handle_unref): And when the deleted shared part is pointed
1220 to as a handle is deleted
1222 2005-10-20 Dick Porter <dick@ximian.com>
1224 * processes.c (process_set_current): If the expected process
1225 handle slot doesn't contain the correct pid, create a new handle.
1227 * handles.c (_wapi_search_handle): When the search doesn't find
1228 anything, return failure instead of the last handle we looked at.
1229 (_wapi_handle_ref, _wapi_handle_unref): Don't try to ref or unref
1230 unused handles (makes tracking refcounting bugs easier.)
1232 2005-10-19 Dick Porter <dick@ximian.com>
1235 * handles-private.h:
1239 * collection.c (_wapi_handle_collect): Remove the shared handle
1240 indirection layer, and use locking instead. Delete other
1241 complexity that is no longer needed. Refcount shared handles and
1242 delete them when needed, but keep the timestamps so that orphaned
1243 handles will be cleaned up eventually.
1245 * shared.c (_wapi_shm_file): Add processor, OS and struct size
1246 info to the shared file names, to cope with dual-boot and 32/64bit
1247 size issues. Fixes bug 75839.
1249 * wait.c (WaitForMultipleObjectsEx): No need to distinguish
1250 between shared handles and private, as the wait functions cope
1251 with both together now.
1253 2005-10-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1255 * io.c: removed NO_SIGPIPE macro.
1256 * sockets.c: no need for MSG_NOSIGNAL or ignoring SIGPIPE.
1258 2005-10-11 Dick Porter <dick@ximian.com>
1260 * sockets.c (_wapi_getsockopt): Translate SO_ERROR results into
1263 * error.c (errno_to_WSA): Don't return a bogus error if someone
1264 asks to translate errno 0.
1266 2005-10-11 Dick Porter <dick@ximian.com>
1268 * handles.c: Fix several race conditions
1270 2005-10-11 Miguel de Icaza <miguel@novell.com>
1272 * io.c: no need to block SIGPIPE anymore, as it is ignored.
1274 2005-10-05 Dick Porter <dick@ximian.com>
1276 * threads.c (_wapi_thread_own_mutex, _wapi_thread_disown_mutex):
1277 Keep a reference to mutexes owned by threads, so they won't be
1278 destroyed prematurely. Fixes dotmsnclient crash.
1280 2005-09-26 Sebastien Pouliot <sebastien@ximian.com>
1282 * io.c: Apply patch from #76192 (Can't write files past 2gb on AMD64
1283 (x86_64)) for Brion on IRC (Dick approved it).
1285 2005-09-23 Dick Porter <dick@ximian.com>
1287 * processes.c: Don't wait for processes that have already been
1288 signalled; also fix typo.
1290 * handles.c: Improve locking inside new handle and handle
1291 searching functions.
1293 2005-09-20 Dick Porter <dick@ximian.com>
1296 * processes.c: Periodically waitpid for known process IDs. Fixes
1299 2005-09-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1302 (CreateFile): if the file is a named pipe, treat the handle as a pipe,
1303 not as a file. Fixes bug #76075.
1305 2005-08-27 Zoltan Varga <vargaz@gmail.com>
1307 * atomic.h: Add support for intel icc.
1309 2005-08-25 Zoltan Varga <vargaz@gmail.com>
1311 * io-layer.h: Include winbase.h not WinBase.h.
1313 2005-08-19 Dick Porter <dick@ximian.com>
1315 * threads.c, threads.h, thread-private.h: Use a gsize to store the
1316 thread ID, so it can hold a 64 bit value if needed.
1318 2005-07-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1320 * error.c: map ENOENT to WSAECONNREFUSED. It might happen when
1321 connecting to unix sockets. Closes bug #75632.
1323 2005-07-05 Dick Porter <dick@ximian.com>
1325 * io.c: Make sure SIGPIPE is ignored when calling write(2).
1326 Prevents the runtime exiting when writing to a closed pipe,
1329 2005-06-30 Dick Porter <dick@ximian.com>
1331 * shared.c (_wapi_shm_semaphores_init): Add some helpful error
1332 messages when semget () fails due to lack of resources.
1334 2005-06-21 Dick Porter <dick@ximian.com>
1339 * threads.c: Keep a list of owned mutexes in each thread handle,
1340 so that it is easier to abandon them when the thread exits.
1341 Removes a bottleneck when multiple threads are finishing in
1344 2005-06-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1346 * io.c: (GetLogicalDrives) when a bogus line is read, don't leak memory.
1347 When the buffer has not enough space, close the file before returning.
1349 2005-06-09 Duncan Mak <duncan@novell.com>
1351 * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to
1352 all public headers. Fixes #74919.
1354 2005-05-30 Zoltan Varga <vargaz@freemail.hu>
1356 * atomic.h: Add IA64 atomic ops.
1358 2005-05-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1360 * processes.c: make ExitCode be valid even if the user didn't call
1361 WaitForExit() and is just polling on HasExited.
1363 2005-05-17 Dick Porter <dick@ximian.com>
1365 * io.c (file_getfilesize): Clear the error value, so that files
1366 with sizes with the low bits 0xFFFFFFFF can be distinguished from
1369 2005-05-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1371 * shared.c: forgot to ignore a warning.
1373 2005-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1375 * shared.c: don't display warnings after reboots.
1377 2005-05-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1379 * sockets.c: on windows, getsockopt/setsockopt for send/receive timeout
1380 use an integer in milliseconds. We were using a struct timeval.
1382 2005-05-06 Dick Porter <dick@ximian.com>
1384 * handles-private.h:
1391 * collection.h: Use SysV semaphores for managing access to the
1392 shared memory - in return for the ludicrous api we get
1393 synchronisation primitives that can be cleaned up by the kernel
1394 even when a process quits unexpectedly. This removes the
1397 2005-05-05 Lluis Sanchez Gual <lluis@novell.com>
1399 * handles.c: Always use polling in the waits, since
1400 mono_cond_timedwait can't be interruped by the thread abort signal.
1402 2005-04-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1404 * events.c: calling Set on AutoResetEvent several times has the same
1405 effect as calling it only once if no thread is waiting for it.
1407 2005-04-29 Dick Porter <dick@ximian.com>
1409 * processes.c (EnumProcesses): Use a GArray instead of a GPtrArray
1410 now it's storing pids not handles, also fixes memory leak caused
1411 by unclear glib documentation.
1413 * sockets.c (WSACleanup): Remove unused variable
1415 2005-04-29 Dick Porter <dick@ximian.com>
1417 * handles.c (_wapi_handle_check_share_by_pid): For systems that
1418 don't have file descriptor info in /proc check that the original
1419 opener of a file is still there, if a share violation would
1422 2005-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1425 * handles-private.h: added _wapi_handle_forecch that loops through all
1426 the handles and call a callback function when a handle of the given
1429 * sockets.c: no need to keep open sockets in an array, as we have them
1430 in the handles structure.
1434 2005-04-28 Dick Porter <dick@ximian.com>
1436 * processes.c: Cope with handles that are only around for as long
1437 as the search is running. If we're searching for process handles,
1438 check to see if the process is still running and signal it if not.
1440 * handles.c (_wapi_search_handle): Search in the shared space as
1441 well. Fixed bug 74752.
1444 * handles.c (_wapi_handle_new_from_offset):
1445 _wapi_handle_new_for_existing_ns () was doing exactly the same as
1446 this, so deleted it.
1448 2005-04-26 Dick Porter <dick@ximian.com>
1450 * handles.c: Fix stupid thinko where if a new shared handle is
1451 created but a collection was needed to free some space, it
1452 returned an error anyway. Should fix the messages shown in bug
1455 2005-04-25 Dick Porter <dick@ximian.com>
1457 * handles.c (_wapi_handle_check_share): Only consider mono
1458 processes when looking to see if a file is still being held open,
1459 while checking share permissions.
1461 2005-04-25 Dick Porter <dick@ximian.com>
1465 * wapi-private.h (struct _WapiHandleOps):
1466 * handles.c (_wapi_handle_unref): When destroying handles, save
1467 the handle data and call the close function only after the array
1468 slot has been cleared. This prevents race conditions with file
1469 descriptors, fixing bug 74713.
1471 * mutexes.c: Delete the handle close functions, they didn't do
1474 * error.c (_wapi_get_win32_file_error): Add a mapping for EINTR so
1475 the "Unknown error" g_warning doesn't get displayed.
1477 2005-04-25 Dick Porter <dick@ximian.com>
1480 * threads.c: Make thread handles process-private for now to take
1481 some of the space pressure off the shared memory, while I work on
1484 2005-04-21 Dick Porter <dick@ximian.com>
1486 * handles.c (_wapi_handle_check_share): Make sure there is a "fd"
1487 dir in /proc before blowing away handle info. Fixes bug 74649.
1489 2005-04-21 Dick Porter <dick@ximian.com>
1491 * wait.c (WaitForMultipleObjectsEx): Implement special waits
1493 * handles.c (_wapi_handle_wait_signal_poll_share): Don't return a
1494 timeout, just wait briefly for the private signals and let the
1495 waiting thread test again. This prevents us missing shared
1498 2005-04-21 Dick Porter <dick@ximian.com>
1500 * collection.h (_WAPI_HANDLE_COLLECTION_EXPIRED_INTERVAL): Reduce
1501 the time before a slot is considered too old and deleted. This is
1502 a workaround while I come up with a proper fix.
1504 2005-04-21 Dick Porter <dick@ximian.com>
1509 * handles.c (_wapi_handle_new): Turn assertions into errors.
1511 * collection.c (_wapi_handle_collect): Use symbols not magic
1512 numbers for timeout values
1514 2005-04-19 Dick Porter <dick@ximian.com>
1518 * handles.c (_wapi_handle_count_signalled_handles)
1519 * handles-private.h (_wapi_handle_shared_lock_handle): Use new
1520 shared handle locks in critical sections.
1522 * handles.c (_wapi_handle_new_for_existing_ns): Reuse old handles
1523 if there is already one there.
1525 * handles.c (_wapi_handle_ref): It was possible for a process to
1526 exit before getting around to updating shared handle timestamps,
1529 Tue Apr 19 16:25:47 CEST 2005 Paolo Molaro <lupus@ximian.com>
1531 * threads.c: fix lookup of the thread id in the has table:
1532 always use the id value, not the pointer to the id.
1534 2005-04-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1536 * handles.c: fix handle returned in _wapi_handle_search_handle. Dick
1539 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1541 * io-layer/sockets.c: FIONBIO with a TRUE argument means we want
1542 non-blocking IO, not the other way around.
1544 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1548 * handles-private.h: GetFileType wasn't checking if we have memory
1549 allocated for the handle before dereferencing it. Fixes a FileStream
1552 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1556 * handles-private.h: we were calling g_renew to expand the handle array,
1557 but that might move the memory and we might have pthread conditions or
1558 mutexes in the original memory area that are being used. Now instead of
1559 expanding an existing array, we just create new ones and keep a list of
1560 them. Access to _wapi_private_handles had to be modified accordingly.
1562 2005-04-15 Dick Porter <dick@ximian.com>
1564 * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN
1566 2005-04-14 Raja R Harinath <rharinath@novell.com>
1568 * wapi-private.h: Remove reference to 'daemon-private.h'.
1570 Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro <lupus@ximian.com>
1572 * atomic.h: applied patch from mass@akuma.org (David Waite)
1573 to fix InterlockedExchangeAdd.
1574 Fixed a few other functions, including InterlockedCompareExchange()
1575 which was miscompiled by gcc with optimizations enabled.
1577 2005-04-13 Dick Porter <dick@ximian.com>
1579 * io.c (share_check):
1580 * handles.c (_wapi_handle_check_share): Refine the file check so
1581 that sharing violations within the same process don't cause
1584 2005-04-13 Dick Porter <dick@ximian.com>
1586 * io.c (FindFirstFile): Fix bugs introduced with the merge (bug
1589 2005-04-12 Dick Porter <dick@ximian.com>
1591 The daemon-less io-layer. Extensive lowlevel changes in
1592 handles.c, requiring some corresponding changes in other files
1593 calling these functions. Private_foo structures have been
1596 File descriptor handling differences account for most of the
1597 changes in io.c and sockets.c.
1601 * mutexes.c: Named mutexes are now a distinct type.
1602 * atomic.h: Fix a PPC uninitialised variable warning.
1603 * wait.c: Check conditions before waiting on a condition variable.
1604 * processes.c: Handle process fork and wait without a daemon
1605 (though this has the limitation of only being able to wait for
1608 2005-04-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1615 * sockets.h: removed dead code that deals with async IO.
1617 2005-03-30 Zoltan Varga <vargaz@freemail.hu>
1619 * atomic.c (InterlockedIncrement): Fix fallback implementation of
1620 InterlockedIncrement and InterlockedDecrement. Fixes #74228.
1622 2005-03-29 Sebastien Pouliot <sebastien@ximian.com>
1624 * io-layer.h: Add required header files for compiling with VS.NET.
1626 2005-03-17 Miguel de Icaza <miguel@novell.com>
1628 * io.c: don't fail on NFS when there are no more locks available.
1630 2005-03-09 Dick Porter <dick@ximian.com>
1632 * error.c (_wapi_get_win32_file_error): ENFILE and EMFILE should
1633 map to ERROR_TOO_MANY_OPEN_FILES, not ERROR_NO_MORE_FILES. Fixes
1636 2005-03-09 Dick Porter <dick@ximian.com>
1638 * daemon.c (process_process_fork): Initialise the handle data
1639 before using it in the error case. This is probably the error
1640 we're working around in the previous change. Spotted by Taru Jain
1641 <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.
1643 2005-03-07 Dick Porter <dick@ximian.com>
1645 * daemon.c: It looks like g_shell_parse_argv() can return
1646 argv[0]=NULL somehow, yet still not give an error. Make sure we
1647 don't pass NULL to strrchr(), working around a segfault that
1648 showed up on ZLM testing.
1650 2005-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1652 * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is
1653 the expected error code showed by the test case in bug #73053.
1655 2005-02-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1657 * io.c: another leftover.
1659 Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1661 * io.c: fixed logic in checking errno in rev 40815.
1663 Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1665 * threads.c: we don't depend on the GC checking tls
1667 * processes.c: remove unused ref to GC headers.
1669 Thu Feb 17 19:57:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1671 * io.c: remove _wapi_thread_cur_apc_pending () checks
1672 when the siscall should return immediatly and handle
1673 the case when a syscall is interrupted without
1674 erroring out, but returning a 0 read/write if possible.
1675 Still the cases of read from file need to be handled.
1677 Tue Feb 8 18:28:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1679 * threads.c: make people test with 1 MB stack per thread.
1681 2005-01-17 Dick Porter <dick@ximian.com>
1683 * timefuncs.h: Make WapiFileTime endian-aware, as it's often
1684 cast to and from 64bit ints. Fixes bug 71213.
1686 2005-01-11 Dick Porter <dick@ximian.com>
1688 * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
1691 Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>
1693 * atomic.h: Fix functions on s390.
1695 Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>
1697 * atomic.h: fix some functions on ppc (tests/interlocked.cs).
1699 2005-01-10 Dick Porter <dick@ximian.com>
1701 * misc.c (_wapi_calc_timeout): Guard against overflow when
1702 calculating timeouts. This makes waiting with a large
1703 (Int32.MaxValue) timeout not return immediately.
1705 2004-12-23 Ben Maurer <bmaurer@ximian.com>
1707 * io.c (io_ops): make this `const' so it is shareable (well, only
1708 really shareable if it is statically linked...)
1710 Mon Dec 20 11:58:33 CET 2004 Paolo Molaro <lupus@ximian.com>
1712 * threads.c, threads.h: add accessor to get the pthread_key_t for
1715 2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1717 * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS
1718 if it exists and is not the same as 'src'.
1720 2004-12-01 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1722 * atomic.h : Fix InterlockedCompareExchange for s390/s390x.
1724 2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1726 * processes.c: unquote the cmd path, allow for ' or " when quoting and
1727 pass the quoted program name to the daemon, otherwise the call to
1728 g_shell_unquote in the daemon will break things up.
1730 2004-10-14 Dick Porter <dick@ximian.com>
1732 * sockets.c (_wapi_accept): Revert the previous change. We now
1733 set the accepted socket to have the same blocking status as the
1734 listening socket in managed code. This follows MS behaviour.
1736 2004-10-14 Dick Porter <dick@ximian.com>
1738 * sockets.c (_wapi_accept): On Darwin, make sure a newly
1739 accept()ed socket is blocking. Fixes bug 67355, patch by
1740 grompf@sublimeintervention.com.
1742 2004-10-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1744 * system.c: check the number of online processors instead of the
1745 existing ones. Sanitize return value if it's an error.
1747 2004-10-03 Ben Maurer <bmaurer@ximian.com>
1749 * system.c: Add support for getting the # of cpus.
1751 2004-09-28 Dick Porter <dick@ximian.com>
1753 * io.c (pipe_close_private): Fix one small typo in the last change
1754 that totally hosed process creation with redirected pipes.
1756 2004-09-24 Dick Porter <dick@ximian.com>
1763 * handles-private.h: Cope when a file descriptor is reused while
1764 the handle that thought it owned it is still referenced, instead
1765 of asserting. Probably fixes bug 66479, though we've been unable
1768 2004-09-09 Dick Porter <dick@ximian.com>
1771 * io.c: Set error codes everywhere.
1773 2004-09-06 Dick Porter <dick@ximian.com>
1775 * handles.c (_wapi_handle_unref): Reset the private record's type
1776 (CloseHandle): Check for a fd mapping failure, and return FALSE.
1777 (_wapi_handle_process_fork): Fix long-standing bug in checking
1778 handle return values. Also do the required bookkeeping with the
1779 new process's handles.
1781 * daemon.c: When creating a new process's handles, check whether
1782 the shared space needs to be increased
1784 2004-09-05 Zoltan Varga <vargaz@freemail.hu>
1786 * shared.c (_wapi_shm_file): Fix leaking of filename.
1788 2004-08-19 Dick Porter <dick@ximian.com>
1790 * handles.c (_wapi_handle_count_signalled_handles): Fix thinko
1791 introduced with the fd offset stuff: unlock handles properly when
1792 backing off. Fixes the monologue hang at exit.
1794 2004-08-18 Dick Porter <dick@ximian.com>
1797 * io.c: Check that new fds fit in the table, return error if not
1799 * daemon.c (_wapi_daemon_main):
1800 * handles.c (shared_init): Have all processes agree on a size for
1803 2004-08-17 Dick Porter <dick@ximian.com>
1805 * daemon.c (process_new):
1806 * handles.c (_wapi_handle_new_internal): Cope when the space
1807 reserved for file descriptors is larger than the shared segment
1808 size. Fixes the crash reported when running mono under gdb on
1811 2004-08-16 Dick Porter <dick@ximian.com>
1815 * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
1816 error checking with passed-in file descriptors.
1818 2004-08-11 Dick Porter <dick@ximian.com>
1821 * io.c: Returned handle values are the file descriptor the handle
1825 * handles-private.h:
1826 * daemon.c: Reserve the range of handles that can have the same
1827 values as file descriptors. These won't be used, but the values
1828 will be used as file, console, pipe or socket handles. The fd to
1829 handle mapping is done internally and is invisible to users.
1832 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
1833 reserve a chunk of handle space.
1835 2004-08-04 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1837 * atomic.h: add support for 64-bit S/390
1839 2004-07-22 Dick Porter <dick@ximian.com>
1842 * threads.c: Move the destruction of the internal thread data to
1843 after the thread has been joined. Fixes bug 61418.
1845 2004-07-14 Dick Porter <dick@ximian.com>
1847 * wait.c (test_and_own): When not waiting for all handles to
1848 become signalled, only own and return the lowest. All the
1849 documentation suggests that the old way was correct, but
1850 experimentation shows it actually works like this. Patch by
1851 Sébastien Robitaille
1852 (sebastien.robitaille@croesus.com), fixes bug 61511.
1854 2004-07-09 Ben Maurer <bmaurer@ximian.com>
1856 * threads.c: register roots for gc
1858 2004-07-08 Dick Porter <dick@ximian.com>
1860 * io.c (file_seek): If there is a high 32bit offset part, make
1861 sure the low part isn't sign-extended. Set error codes when
1862 returning failure. Fixes bug 61131.
1864 2004-07-06 Dick Porter <dick@ximian.com>
1866 * io.c (file_setfiletime): Check for underflow when converting to
1867 time_t values. Set error codes when returning failure. Fixes bug
1870 2004-07-05 Dick Porter <dick@ximian.com>
1872 * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable.
1874 * daemon.c (unref_handle): Only destroy a handle if all processes
1875 have released it, not just the current one. Fixes bug 60887.
1877 2004-06-30 Zoltan Varga <vargaz@freemail.hu>
1879 * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
1880 to prevent warnings.
1882 2004-06-24 Dick Porter <dick@ximian.com>
1884 * mutexes.c: Indicate when a named mutex was reused
1886 2004-06-24 Dick Porter <dick@ximian.com>
1888 * threads.c (SuspendThread):
1889 * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a
1890 while loop. See bug 58161.
1892 Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro <lupus@ximian.com>
1894 * io.c: don't use sharemode for on-disk file permissions: it's used
1895 for shared access to the open file.
1897 2004-06-22 Dick Porter <dick@ximian.com>
1899 * events.c (CreateEvent): When creating an auto-reset event that
1900 is initially owned, make sure the set count starts at 1.
1902 2004-06-18 Dick Porter <dick@ximian.com>
1905 * events.c: Auto-reset events need to release one thread for each
1906 time SetEvent() is called. Fixes bug 41292.
1910 * mutexes.c: Scan for mutexes that are still locked by a thread
1911 when it exits. Fixes the MS demo app linked by bug 41292.
1913 * wait.c (test_and_own): Make sure a handle is signalled before it
1916 2004-06-16 Dick Porter <dick@ximian.com>
1918 * timed-thread.c: Call the thread cleanup exit routine before taking
1919 the join mutex, because this could deadlock if another thread tries
1920 to join in the meantime. This fixes the hang-at-exit problem seen
1923 2004-06-03 Lluis Sanchez Gual <lluis@ximian.com>
1925 * threads.c: Implemented SleepEx.
1926 * threads.h: Fixed SleepEx signature.
1928 2004-06-03 Miguel de Icaza <miguel@ximian.com>
1930 * threads.c: When running under valgrind, do not allocate too much
1931 stack, as Valgrind default is 1 meg.
1933 2004-05-27 Dick Porter <dick@ximian.com>
1936 * io.c: Implemented LockFile() and UnlockFile()
1938 2004-05-21 Dick Porter <dick@ximian.com>
1940 * io.c (CreateFile): Check for existing share modes when opening
1944 * handles-private.h:
1945 * daemon-messages.h:
1946 * daemon.c: Maintain a hash of file share modes, keying on device
1947 and inode (to cope with symlinks.)
1949 2004-05-20 Lluis Sanchez Gual <lluis@ximian.com>
1951 * daemon-messages.c: Retry if the communication with the daemon is
1952 interrupted by a signal.
1953 * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped.
1954 Only return an error in this case if there is something in the apc queue
1955 (which means that it is an interruption requested by the "user").
1956 * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as
1957 true since the wait is small.
1958 * shared.c: Retry write calls when interrumped by a signal.
1959 * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which
1960 returns TRUE if there are pending asynchronous calls (APC) for the
1961 provided thread. Also added _wapi_thread_dispatch_apc_queue which calls
1962 the enqueued APCs. Defined a new struct ApcInfo that holds information
1963 about an enqueued APC.
1964 * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same
1965 as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue.
1966 These last two methods call the corresponding apc methods in
1967 thread-private using the provided thread handle.
1968 * threads.h: Added QueueUserAPC.
1969 * uglify.h: Added WapiApcProc (needed by QueueUserAPC).
1970 * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and
1971 WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support
1972 for APCs in those two methods and also in SleepEx.
1974 2004-05-17 Dick Porter <dick@ximian.com>
1976 * io.c (CopyFile): Speed up. Fixes bug 57859.
1978 2004-05-13 Dick Porter <dick@ximian.com>
1979 * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current
1980 thread doesn't own the mutex, rather than assert()ing.
1982 2004-05-11 Dick Porter <dick@ximian.com>
1984 * shared.c (_wapi_shm_attach): Cope when a previous daemon startup
1985 attempt failed, leaving shared files that look like a daemon is
1988 2004-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1991 (SetFileAttributes): don't the the exec bit if the corresponding read
1994 2004-05-10 Zoltan Varga <vargaz@freemail.hu>
1996 * io.c (FindFirstFile): Fix invalid free.
1998 2004-05-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2000 * io.c: translate from GFileError to errno codes and don't free
2001 variables right after calling mono_io_scandir, as we may overwrite
2004 2004-05-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2006 * io.c: g_dir_open return ENOENT for directories on which we don't have
2007 read/execute permission, while returning EPERM for anything below those.
2008 So, change ENOENT by EPERM if the directory exists.
2010 2004-05-07 Dick Porter <dick@ximian.com>
2012 * io.c (SetFileAttributes): Don't have failed chmod()s cause a
2013 "file not found" error. Fixes bug 54032.
2015 2004-05-07 Dick Porter <dick@ximian.com>
2017 * io.c (FindFirstFile): Comment out a windows-compatibility check
2018 that breaks when directories have metachars in their names.
2019 Workaround for bug 58116.
2021 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2023 * io.c: fixed for FindFirstFile for empty directories. Closes
2026 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2028 * processes.c: set the start time for the current process. Fixes bug
2031 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2033 * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
2034 * io.c: implemented scandir using glib functions.
2036 2004-05-04 Dick Porter <dick@ximian.com>
2038 * daemon.c (read_message): Return FALSE on error so the GSource
2039 callback itself can return FALSE. Cures the infinite loop poll()
2041 * shared.c: Fix some daemon startup race conditions.
2043 2004-04-29 Miguel de Icaza <miguel@ximian.com>
2045 * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k,
2046 use the stack, do not use dynamic memory.
2048 2004-04-29 Zoltan Varga <vargaz@freemail.hu>
2050 * io.c: Add scandir implementation for platforms which do not have
2053 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2055 * io.[ch]: implemented GetLogicalDriveStrings.
2057 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2060 * sockets.c: use the field name from configure when accessing sigval
2061 pointer field. Makes this work on the Mac.
2063 2004-04-28 Bernie Solomon <bernard@ugsolutions.com>
2065 * atomic.c: (InterlockedExchange) fix typo for
2068 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2071 * sockets.c: added check for sys/aio.h.
2073 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2075 * error.[ch]: added _wapi_get_win32_file_error...
2076 * io.c: ... which was _wapi_get_win32_error here.
2077 * sockets.c: rename the function calls here too.
2079 2004-04-28 Dick Porter <dick@ximian.com>
2081 * daemon-messages.c: Avoid a deadlock when a thread is killed while
2082 waiting for the daemon by using a recursive mutex. Helps bug 56699.
2084 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2086 * io.c: fixed leak in async_notifier().
2088 * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl
2091 * threads.c: removed old comment.
2093 2004-04-26 David Waite <mass@akuma.org>
2095 * daemon-messages.h:
2102 * wapi-private.h: remove comma from end of enumeration declarations
2103 * status.h: cast unsigned int types to int for enum assignment
2105 2004-04-26 David Waite <mass@akuma.org>
2108 * timefuncs.c: declare 64-bit constants as long long types (i.e.
2111 2004-04-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2113 * socket-wrappers.h: _wapi_socket == WSASocket now. Added
2114 WSA_FLAG_OVERLAPPED.
2116 * sockets.c: new unused parameters for _wapi_socket.
2118 2004-04-22 Miguel de Icaza <miguel@ximian.com>
2120 * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle
2121 the fact that MacOS X is a piece of junk (sem_init is *defined* in
2122 the libc, but they return `not implemented').
2124 2004-04-22 Dick Porter <dick@ximian.com>
2127 * handles-private.h: Reference the handle when it is locked, so
2128 that another thread can't blow it away while we're waiting for it
2129 to become signalled.
2140 * handles-private.h:
2143 * daemon-messages.c:
2144 * critical-sections.c:
2145 * atomic.c: Added pthreads cleanup handlers and error asserts
2148 * handles.c: Fixed the gcc "variable might be used uninitialised"
2149 warnings. They can't happen, but gcc doesn't know that
2150 g_assert()s don't return.
2152 Fixed the declaration of _wapi_handle_process_kill() so that it
2153 expects the correct type for the pid.
2155 * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that
2156 hasn't been used in ages and just made the code more complex.
2158 2004-04-17 Zoltan Varga <vargaz@freemail.hu>
2160 * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
2161 warnings. Fixes #57168.
2163 2004-04-16 Dick Porter <dick@ximian.com>
2165 * threads.c (Sleep): Using div(3) with a negative (when signed)
2166 numerator causes the quotient to be 0 and the remainder to be the
2167 numerator. This feeds a small negative value to nanosleep(3),
2168 which will return immediately and cause a busy wait. Fixes bug
2171 2004-04-15 Dick Porter <dick@ximian.com>
2174 * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3)
2175 and fnmatch(3) instead of glob(3). glob() can't cope with being
2176 given filenames containing metachars. This fixes bug 40557.
2178 2004-04-14 Bernie Solomon <bernard@ugsolutions.com>
2180 * security.c: #warning is a GCC-ism
2182 2004-04-13 Sebastien Pouliot <sebastien@ximian.com>
2184 * security.c: Removed GetUserName as glib g_get_user_name does a
2185 better (portability) job. Added ImpersonateLoggedOnUser and
2188 2004-04-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2190 * mono-mutex.h: move pthread_mutex_timedlock declaration to...
2191 * mono-mutex.c: ...here. It was causing a warning that prevented
2192 libgdiplus compilation.
2194 2004-04-04 Miguel de Icaza <miguel@ximian.com>
2196 * security.c (GetUserName): Make it work on MacOS X
2198 2004-04-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2200 * security.c: use getpwuid_r if available. This one is thread-safe.
2202 2004-04-02 Sebastien Pouliot <sebastien@ximian.com>
2204 * Makefile.am: Added security.c|h.
2205 * security.c: New file for security related functions. Added function
2206 GetUserName to fix #56144.
2207 * security.h: New. Header file for security.c
2208 * wapi.h: Added include for security.h
2210 2004-03-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2212 * daemon-messages.h: added kill structs.
2214 * daemon.c: implemented process_process_kill.
2215 * handles-private.h: define process_process_kill.
2216 * handles.c: implemented _wapi_handle_process_kill.
2217 * processes.[ch]: implemented TerminateProcess.
2219 2004-03-25 Bernie Solomon <bernard@ugsolutions.com>
2221 * daemon.c (rem_fd): On solaris you seem to get an
2222 error even after removing the input source so don't
2223 try and rem_fd it twice.
2225 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
2227 * daemon.c: in process_post_mortem, If the child terminated due to the
2228 receipt of a signal, the exit status must be based on WTERMSIG, since
2229 WEXITSTATUS returns 0 in this case.
2231 2004-03-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2233 * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.
2235 2004-03-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2237 * daemon.c: only call getdtablesize () once.
2238 * processes.c: wait 500 ms to check if execve failed and throw the same
2239 exception as MS on failure. Fixes bug #32809.
2241 2004-03-17 Bernie Solomon <bernard@ugsolutions.com>
2243 * io.c (async_notifier): use "union sigval" rather
2244 than sigval_t as Solaris doesn't have sigval_t
2245 (which isn't in IEEE 1003.1 either).
2247 2004-03-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2249 * io.c: added debug stuff and removed a few redundant lines in
2252 2004-03-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2254 * io-private.h: added new fields for file structure. Declare
2255 _wapi_io_add_callback.
2257 * io.c: added _wapi_get_win32_error, support aio_read/write in
2258 file_read/write. Implemented _wapi_io_add_callback, which is where
2261 * io.h: added new fields for WapiOverlapped and typedef for the
2264 * processes.c: fixed off-by-one bug when handling environment variables
2267 * threads.[ch]: implemented BindIoCompletionCallback.
2269 * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE.
2271 2004-03-14 Zoltan Varga <vargaz@freemail.hu>
2273 * socket-wrappers.h: Remove extra semicolon.
2275 2004-03-03 Dave Camp <dave@ximian.com>
2277 * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
2278 Use a new main context.
2280 2004-03-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2283 (GetFileAttributes): set the error depending on errno instead of
2284 setting ERROR_FILE_NOT_FOUND always. See bug #55160.
2286 2004-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2289 (CopyFile): free the buffer on error.
2291 (WSAIoctl): free the buffer on error.
2293 2004-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2295 * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT.
2297 * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW
2298 using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style.
2300 2004-01-27 Bernie Solomon <bernard@ugsolutions.com>
2302 * shared.c (_wapi_shm_file): add hostname
2303 to shared data file names to handle NFS mounted
2306 Mon Jan 26 16:15:03 CET 2004 Paolo Molaro <lupus@ximian.com>
2308 * sockets.h: remove obsolete soklen_t typedef.
2310 Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>
2312 * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket
2313 wrappers to its own non-installed header file.
2315 2004-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2318 (FindFirstFile): unlock the handle if FindNextFile fails.
2319 (FindNextFile): g_free a couple of pointers before retrying.
2322 (WaitForMultipleObjects): if only one handle provided, use
2323 WaitForSingleObject.
2325 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2327 * handles-private.h: (_wapi_handle_type) check
2328 for segment in range before using it
2330 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2332 * thread-private.h: _wapi_thread_ops is now const
2335 Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>
2337 * threads.c, timed-thread.c, timed-thread.h: use mach
2338 semaphores on Darwin (MacOSX) since the posix ones
2339 are mostly broken there (threads are not created suspended
2340 and they can start executing before they are fully initialized
2341 like in tests/thread-static.cs).
2343 Mon Dec 22 17:18:45 CET 2003 Paolo Molaro <lupus@ximian.com>
2345 * atomic.h: ppc fixes.
2347 2003-12-19 Bernie Solomon <bernard@ugsolutions.com>
2349 * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
2352 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2354 * shared.c: (_wapi_shm_open) make scratch file
2355 not have to immediately regrow to avoid remaps
2356 (HPUX can't cope with these).
2357 (_wapi_shm_attach) use actual size of file
2358 to set scratch data_len for the creating process.
2360 * handles.c: (_wapi_handle_new_internal) make
2361 sure mutex & cond var are initialized even for
2362 non process shared ones.
2363 (_wapi_handle_unref) always call destroy
2364 routines on mutex & cond var
2366 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2368 * daemon.c: change channel data structure so
2369 input sources are removed from glib event loop
2370 properly. xsp works better on Solaris and
2373 2003-12-12 Bernie Solomon <bernard@ugsolutions.com>
2375 * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
2376 definition with file & line number for non-GCC
2379 2003-12-08 Bernie Solomon <bernard@ugsolutions.com>
2381 * Makefile.am: make sure hppa_atomic.s is in distribution
2383 2003-12-01 Dick Porter <dick@ximian.com>
2386 * mutexes.c (CreateMutex):
2387 * mutex-private.h (struct _WapiHandle_mutex):
2388 * handles.c: Look up certain handle types by name, in a shared
2389 namespace. Currently only mutex handles have this implemented.
2392 * semaphores.c (CreateSemaphore):
2393 * events.c (CreateEvent): Fix signature
2395 2003-11-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2397 * io.c: don't call g_free before testing errno as it may modify it.
2398 If the path exists, return an error if it's not a directory. Fixes
2401 2003-11-20 Dick Porter <dick@ximian.com>
2403 * io.c: Missed a little-endian UTF16 conversion. Patch from
2404 Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.
2406 2003-10-29 Dick Porter <dick@ximian.com>
2408 * io.c (MoveFile): If the move crosses filesystems, try and fall
2409 back to copy and delete. Patch from Jörg Rosenkranz
2410 (JoergR@voelcker.com), fixes bug 50298.
2412 2003-10-28 Dick Porter <dick@ximian.com>
2414 * io.c: Use the new encoding conversion to cope with non-utf8
2415 locales in filenames.
2417 * processes.c: Ditto for process arguments.
2419 Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro <lupus@ximian.com>
2421 * atomic.h: some ppc inline asm fixes (incorrect use of labels,
2422 incorrect register constraints, incorrect clobber lists).
2424 2003-10-13 Bernie Solomon <bernard@ugsolutions.com>
2426 * Makefile.am hppa_atomic.s: add HP 64bit
2427 implementation of atomic ops
2429 2003-10-13 Zoltan Varga <vargaz@freemail.hu>
2431 * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
2432 a conditional for platforms that don't have it.
2434 2003-10-09 Bernie Solomon <bernard@ugsolutions.com>
2436 * threads.c: (CreateThread) use stacksize argument
2437 if non-zero - change default for 64 bits to 4Mb
2439 2003-09-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2441 * sockets.c: set last error when socket creation fails. This shed some
2442 light on bug #49015.
2444 2003-09-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2446 * processes.c: fixed bug #48973: we only change \ by / for the argument
2447 to be used as command.
2448 When getting the program name from the args, don't let the space between
2451 2003-09-24 Bernie Solomon <bernard@ugsolutions.com>
2453 * atomic.h atomic.c: fix sparc so lock is
2454 global, increment does so and it compiles under Sun compiler.
2456 2003-09-22 Bernie Solomon <bernard@ugsolutions.com>
2458 * handles.c: include <string.h> directly as may
2459 not be nested in <sys/un.h> like Linux
2461 2003-09-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2464 (DeleteFile): call SetLastError on failure. Fix by
2465 richard.torkar@htu.se (Richard Torkar). Closes bug #48222.
2467 2003-09-15 Lluis Sanchez Gual <lluis@ximian.com>
2469 * daemon.c: In compare_process(), discard handles already signalled.
2471 2003-09-02 Dick Porter <dick@ximian.com>
2473 * io.c: Work around glib brain-dead assumptions about utf8-encoded
2474 filenames. Fixes bug 30781.
2476 2003-08-28 Dick Porter <dick@ximian.com>
2478 * critical-sections.c: Patch from Bernie Solomon
2479 <bernard@ugsolutions.com> to emit a warning if locking a critical
2482 2003-07-23 Dick Porter <dick@ximian.com>
2485 * daemon.c (maybe_exit): Avoid the race condition when the daemon is
2486 closing but another client comes along when the shared data is still
2487 visible. Should fix bugs 33671 and 35213.
2489 2003-07-23 Dick Porter <dick@ximian.com>
2491 * handles.c: Initialise handle mutex and cond. Fix by
2492 Bernie Solomon <bernard@ugsolutions.com>
2494 2003-07-15 Dick Porter <dick@ximian.com>
2496 * timed-thread.c (timed_thread_start_routine): Fix virtual memory
2497 leak when threads quit. Fixes bug 44067.
2499 Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro <lupus@ximian.com>
2501 * io.c: never add write permission for group or others in
2502 SetFileAttributes ().
2504 2003-06-17 Dick Porter <dick@ximian.com>
2506 * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
2507 ignore the unsupported ones ("fixes" bug 44977).
2509 2003-06-17 Lluis Sanchez Gual <lluis@ximian.com>
2511 * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for
2512 high ms values (there was an overflow).
2514 2003-06-17 Zoltan Varga <vargaz@freemail.hu>
2516 * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.
2518 2003-06-11 Dick Porter <dick@ximian.com>
2520 * shared.c: Fix shared directory creation. Patch from
2521 Pablo Baena <pbaena@uol.com.ar>
2523 2003-06-10 Dick Porter <dick@ximian.com>
2525 * atomic.c: Delete the useless compile warning
2527 2003-06-09 Dick Porter <dick@ximian.com>
2529 * daemon.c: Lookup env as a string array. Fixes bug 44289. Also
2530 make setting the process handle value in the environment actually
2533 * processes.c: Pretty up the process name, if it happens to be
2534 "mono" such as when another mono process forks "mono foo.exe"
2536 2003-06-05 Dick Porter <dick@ximian.com>
2538 * processes.c (process_set_current): Don't do an expensive handle
2539 search at application startup, check the environment to see if the
2540 process handle has already been created.
2542 * io.c: Don't do an expensive handle search when creating stdin,
2543 stdout and stderr handles, just create them all the first time one
2550 * handles-private.h:
2551 * daemon-messages.h:
2553 * daemon.c: Support for "unlimited" number of handles and scratch
2556 Speed up application startup by passing process handle in the
2557 environment, rather than let the app scan all handles (which gets
2558 really slow when there are more than a few thousand to check.)
2560 Initialise some structs passed to syscalls, noticed by valgrind.
2563 2003-05-20 Dick Porter <dick@ximian.com>
2565 * io.c (FindFirstFile): Include . files in the glob. Fixes bug
2568 2003-05-19 Dick Porter <dick@ximian.com>
2570 * threads.c: Set the new thread's stack size to 2M. Fix needed
2571 for BSD, reported by Martin Dvorak <md@9ll.cz>
2573 2003-05-16 Dick Porter <dick@ximian.com>
2576 * io.c: Implement GetTempPath()
2578 2003-05-16 Dick Porter <dick@ximian.com>
2580 * processes.c (CreateProcess): Set some error codes
2582 2003-05-12 Dick Porter <dick@ximian.com>
2584 * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
2585 Patch from Martin Dvorak <mdvorak@ninell.cz>.
2587 2003-05-10 Dick Porter <dick@ximian.com>
2589 * io.c (CopyFile): Copy file mode as well as file data. Based on
2590 suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
2593 2003-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2595 * handles.c: don't call GC_gcollect when creating new handles.
2597 2003-05-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2599 * handles.c: added some debugging code. Call GC_gcollect
2600 before creating a new handle. It makes Lupus' test run smoother and
2601 faster (from 62 to 83 request per second). Notice that calling
2602 GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does
2603 not improve nor degrade the performance, so i don't do it.
2605 2003-05-02 Dick Porter <dick@ximian.com>
2607 * sockets.c: Rearrange closesocket() and socket_close_private(),
2608 and remember to unref the handle, so we don't leak socket handles.
2609 Fix from Pelle Johnsen <pelle.johnsen@mail.dk>
2611 2003-04-11 Dick Porter <dick@ximian.com>
2613 * atomic.h: ARM atomic operations by Malte Hildingson
2614 <tds00mahi@tellus.thn.htu.se>
2616 Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>
2618 * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.
2620 2003-04-03 Martin Baulig <martin@ximian.com>
2622 The following change is conditional to `WITH_INCLUDED_LIBGC'
2623 which is not yet enabled by default.
2625 * threads.c (SuspendThread, ResumeThread): Fully implemented this.
2626 (gc_init): New static function; install a signal handler for
2627 SIGPWR which is used to suspend threads. [FIXME: it SIGPWR
2628 doesn't exist on all Unix systems, we need to find another
2630 (mono_wapi_push_thread_stack): New public function. Tells the
2631 garbage collector about the current stack pointer of a suspended
2634 2003-04-03 Martin Baulig <martin@ximian.com>
2636 * timed-thread.h (TimedThread): Added `suspended_sem',
2637 `suspend_count' and `stack_ptr'.
2639 2003-03-28 Dick Porter <dick@ximian.com>
2641 * atomic.h: PPC support gratiously donated to the public domain
2642 by John Duncan <jddst19@mac.com>
2644 2003-03-20 Dick Porter <dick@ximian.com>
2646 * sockets.c (_wapi_connect): If connect() fails with EACCES, try
2647 setting SO_BROADCAST and connecting again. Fixes bug 39178.
2649 2003-03-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2651 * processes.c: included Jerome Laban's patch and call SetLastError when
2652 the executable is not found.
2654 2003-03-03 Dick Porter <dick@ximian.com>
2656 * io.c (CreateFile): Try opening directories readonly, so that
2657 timestamps can be adjusted. Patch by Elan Feingold
2658 <efeingold@mn.rr.com>.
2660 2003-02-25 Dick Porter <dick@ximian.com>
2662 * shared.c (_wapi_shm_attach): Return a failure code on system
2663 call errors, rather than exiting.
2665 2003-02-21 Dick Porter <dick@ximian.com>
2667 * processes.c (GetCurrentProcessId): Use the current process
2668 handle to return the process ID, as getpid() is unreliable
2669 (linuxthreads gives each thread a different pid). Fixes bug
2672 2003-02-21 Dick Porter <dick@ximian.com>
2674 * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug
2677 2003-02-11 Dick Porter <dick@ximian.com>
2680 * timefuncs.c: Added GetTickCount()
2682 2003-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2684 * error.c: added WSA_EHOSTUNREACH mapping.
2686 2003-01-26 Miguel de Icaza <miguel@ximian.com>
2688 * io.c (SetFileAttributes): This routine is not currently
2689 implemented for the general case, but I added a special case to
2690 set the executable bit on Linux.
2692 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
2694 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
2696 2003-01-08 Dick Porter <dick@ximian.com>
2698 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
2700 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
2702 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2703 Check for an implementation which says it supports
2704 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
2705 defines the symbol. Defined but with a value of -1 still
2706 means that it is unsupported.
2708 2002-12-08 Martin Baulig <martin@ximian.com>
2710 * handles.c (_wapi_handle_new): Create new non-shared handles with
2711 an initial refcount of 1, not 0.
2713 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
2715 * threads.c (TlsGetValue): removed unnecessary mutex
2717 2002-11-20 Dick Porter <dick@ximian.com>
2719 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
2720 need to store their data structure too.
2722 * threads.c: Make sure the threading data is initialised wherever
2725 2002-11-15 Dick Porter <dick@ximian.com>
2727 * timed-thread.c: Removed unneeded parameters in
2728 _wapi_timed_thread_attach().
2730 * threads.c: Renamed AttachThread() to make it not look like
2731 external API. Removed unneeded parameters.
2733 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2735 * error.[ch]: added errno_to_WSA (). It displays a warning and return
2736 WSASYSCALLFAILURE if there is no error mapping for the given errno,
2738 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
2740 2002-10-31 Dick Porter <dick@ximian.com>
2743 * io.c: Define and use INVALID_FILE_ATTRIBUTES
2745 2002-10-07 Dick Porter <dick@ximian.com>
2748 * daemon.c: Use a more accurate time source for process start and
2751 2002-10-03 Dick Porter <dick@ximian.com>
2755 * threads.c: Fixes for freebsd. Make sure that mutex and condition
2756 creation and deletion happen in the process that owns them, when
2757 POSIX shared thread objects aren't supported. This breaks on
2758 freebsd, as pthread_t is a pointer to data.
2760 2002-10-02 Dick Porter <dick@ximian.com>
2762 * shared.c: Use mmap() instead of sysv shm for the shared data.
2764 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
2768 * daemon.c: mmap()ed regions survive fork, so just pass the
2769 pointer to _wapi_daemon_main instead of mapping it again.
2771 2002-10-01 Dick Porter <dick@ximian.com>
2773 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
2774 Unfortunately libgc uses the same thread suspend technique that I
2775 want to, and the two don't mix: libgc will deadlock when it tries
2776 to stop the world if a thread has already been suspended by
2777 someone else. Just do the simple suspended create rather than the
2778 general purpose thread suspension for now.
2780 * threads.c: Pass create flags to the timed_thread create call, to
2781 implement suspended thread creation. ResumeThread() partially
2782 implemented, to cope with the case where a newly created but
2783 suspended thread is launched.
2785 2002-09-30 Dick Porter <dick@ximian.com>
2787 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
2790 2002-09-27 Dick Porter <dick@ximian.com>
2792 * semaphores.c: Only include semaphore.h if it's present. Patch
2793 for BSD from jmmv@hispabsd.org (Julio Merino).
2795 2002-09-27 Dick Porter <dick@ximian.com>
2797 * processes.c: Pass environment and working directory to the
2798 daemon when forking. Don't let argv[0] be duplicated when looking
2799 for the program name. Implement EnumProcessModules (simple
2800 version for now, lsof-style later if needed), GetModuleBaseName,
2801 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
2802 aren't available on Linux).
2804 * process-private.h: Store the process name, and the working set
2808 * handles-private.h: New functions to store and retrieve an array
2809 of strings in the scratch space
2811 * daemon.c: Don't miss deleting some handles when a client exits
2812 (we used to rely on the client doing the final cleanup, but
2813 obviously if the client is no longer there the daemon has to do
2816 Process forking now sets the environment and the working
2819 * io.c: Don't confuse fd 0 with an unassigned handle struct
2821 * atomic.h: Add a google cache alternative to the msdn URL
2823 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2826 (_wapi_recvfrom): added ECONNRESET to the switch.
2828 2002-09-24 Mark Crichton <crichton@gimp.org>
2830 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
2833 2002-09-19 Mark Crichton <crichton@gimp.org>
2835 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
2836 dont have Linux's abstract filesystem for sockets.
2838 2002-09-19 Mark Crichton <crichton@gimp.org>
2840 * atomic.h: Added SPARC atomic asm code.
2841 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2842 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
2843 Solaris 9, however, the code paths don't seem to work. More testing
2844 on the shared case is *really* needed.
2846 2002-09-03 Dick Porter <dick@ximian.com>
2849 * threads.c: Removed PosixKillThread(), because it's not in the
2852 2002-08-20 Dick Porter <dick@ximian.com>
2854 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
2855 multiples of 4 bytes, to keep header structures aligned. Needed
2856 for sparc, at least. (Patch from crichton@gimp.org)
2858 * handles.c: Removed 'disable_shm' variable (we've defaulted to
2859 building with shm enabled for months now)
2861 2002-08-19 Dick Porter <dick@ximian.com>
2863 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
2864 for legacy NeXT-based systems.
2866 2002-08-12 Dick Porter <dick@ximian.com>
2868 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
2869 from Joseph Wenninger <kde@jowenn.at>)
2871 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
2873 * threads.c: use fast spinlocks by default
2875 2002-08-02 Dick Porter <dick@ximian.com>
2877 * io.c (GetStdHandle): Add a handle reference when returning a
2878 duplicate console handle. This fixes the unref_handle errors in
2881 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
2883 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
2886 2002-08-01 Dick Porter <dick@ximian.com>
2888 * threads.c: Use atomic spinlocks in TLS functions
2891 * Makefile.am: Added mono-spinlock.h
2893 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
2895 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
2896 these are needed for sendmsg() and also for struct msghdr (at
2897 least on Solaris). Solaris still won't build because struct msghdr
2898 doesn't have msg_flags, msg_control, or msg_controllen members.
2899 (CMSG_SPACE): Define for systems that don't have it.
2902 2002-07-20 Dick Porter <dick@ximian.com>
2908 * handles.c: Implemented pipe handles
2911 * daemon.c: Fixed bug in handle closing.
2914 * daemon.c: Forked processes now close all open file descriptors.
2916 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
2918 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
2921 2002-07-19 Martin Baulig <martin@gnome.org>
2923 * threads.c (ExitThread): Call exit() if no threads has been
2926 2002-07-17 Dick Porter <dick@ximian.com>
2928 * daemon-messages.c: Freebsd fixes from Andreas Kohn
2929 <andreas.kohn@gmx.net>
2931 2002-07-15 Dick Porter <dick@ximian.com>
2933 * io.c: Removed bogus console_flush() method, that was just cut
2934 and pasted from file_flush when I separated the two handle types.
2936 2002-07-12 Dick Porter <dick@ximian.com>
2938 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
2939 flags. Fixes bug 27633.
2941 2002-07-12 Dick Porter <dick@ximian.com>
2945 * daemon.c: Use size of sockaddr_un.sun_path from config.h
2947 2002-07-12 Dick Porter <dick@ximian.com>
2949 * processes.c (CreateProcess): Send stdin, stdout and stderr
2950 handles if the startup info doesnt specify new ones
2952 * io.c (GetStdHandle): Return the same handle when the same
2953 standard handle is requested
2955 * handles.c: Pass file descriptors when forking
2957 * daemon.c: Use supplied file descriptors when forking a new
2960 * daemon-messages.h:
2961 * daemon-messages.c: Pass stdin, stdout and stderr file
2962 descriptors to the daemon (used when forking)
2964 2002-07-11 Miguel de Icaza <miguel@ximian.com>
2966 * daemon.c (_wapi_daemon_main): Use sizeof
2967 (main_socket_address.sun_path) instead of hardcoded 108 value.
2969 * handles.c (shared_init): Use sizeof
2970 (shared_socket_address.sun_path) instead of hardcoded 108 value.
2972 2002-07-10 Dennis Haney <davh@davh.dk>
2976 * daemon.c: Lots of documentation, some added error checking, and
2977 code readability improvements.
2979 * daemon-messages.h: Add the Error request type to improve error
2982 * daemon-messages.c: Do a bit more error checking on send() and
2983 recv(), and log errors with a higher severity level.
2985 2002-07-04 Dick Porter <dick@ximian.com>
2987 * daemon.c (process_process_fork): Fix argument handling, due to
2988 buggy understanding of g_strsplit() behaviour.
2990 2002-07-03 Dick Porter <dick@ximian.com>
2993 * threads.c: Implement OpenThread(). Define access-control values
2999 * Makefile.am: Added access.h, to hold shared access-control
3002 2002-07-02 Dick Porter <dick@ximian.com>
3004 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
3006 2002-07-02 Dick Porter <dick@ximian.com>
3008 * handles.c (shared_init): Make a second attempt to contact the
3009 daemon if the shared memory attach succeeds, but the connect()
3010 fails. (This copes with the daemon crashing without cleaning up
3016 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
3017 the daemon, it's now built into the library.
3019 2002-06-25 Dick Porter <dick@ximian.com>
3022 * handles-private.h:
3023 * daemon-messages.h:
3024 * daemon.c: Process forking and handle data management
3027 * process-private.h:
3028 * processes.c: Process forking and other support functions
3030 2002-06-25 Dick Porter <dick@ximian.com>
3032 * versioninfo.h: PE resource decoding
3034 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
3035 to be told the string length
3037 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
3038 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
3041 2002-06-12 Dick Porter <dick@ximian.com>
3044 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
3045 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
3046 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
3048 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
3050 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
3051 when writing to a closed socket.
3053 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
3055 * mono-mutex.c (mono_once): New convenience function for my
3060 * critical-sections.c:
3068 * atomic.c: Use mono_once() rather than pthread_once().
3070 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
3072 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
3073 if multiple threads all try to call _wapi_handle_new() before the
3074 shared data has been initialized, it is possible that we could get
3075 into a condition where shared_init() is being executed and later
3076 threads will pass by pthread_once() due to the fact that it has
3077 already been called and so therefor will attempt to use the shared
3078 data before it has been completely initialized. If we instead use
3079 a standard mutex locking mechanism around shared_init(), we can
3080 avoid the situation entirely. By wrapping the mutex locking in a
3081 check to see if we've already initialized the data, we can even
3082 avoid wasting resources by having to lock/unlock the mutex in any
3083 later calls (the only time we'd have to worry about
3084 locking/unlocking is the initial race to call shared_init() at
3087 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
3089 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
3091 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
3093 * daemon.c, handles.c: rename "sun" local var since it's apparently
3094 a #define on Solaris.
3096 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
3098 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
3101 2002-05-15 Dick Porter <dick@ximian.com>
3103 * wait.c: Fix a deadlock in WaitForMultipleObjects
3105 2002-05-14 Dick Porter <dick@ximian.com>
3107 * io.c: Fix a cut&paste error, found by
3108 Jaroslaw Kowalski <jarek@atm.com.pl>
3110 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
3114 2002-05-09 Dick Porter <dick@ximian.com>
3120 * handles-private.h:
3122 * Makefile.am: Remove now-unused file wait-private.h
3124 2002-05-08 Dick Porter <dick@ximian.com>
3126 * shared.c: Better error messages, and report when daemon
3127 connection fails rather than blocking forever. Do some more
3128 shared memory sanity checking.
3130 * handles.c: Better error messages when connecting to shared
3131 memory and the handle daemon. Fall back to non-shared handles if
3132 an error occurs. Set the default back to 'shared handles'. Fix a
3133 crashing bug in scratch space allocation that mangled the block
3136 2002-05-07 Miguel de Icaza <miguel@ximian.com>
3138 * handles.c (shared_init): Disable SHM for now, people have too
3139 many problems with this, and the diagnostics are not helping.
3141 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
3143 * io.c: CreateFile sets win32 last error.
3145 2002-05-05 Dick Porter <dick@ximian.com>
3148 * handles-private.h:
3154 * process-private.h:
3156 * semaphore-private.h:
3160 * event-private.h: Simplify the WapiHandleOps struct: take out all
3161 the file-specific entries, leaving just the items that operate on
3162 handles themselves. Split the close operation into shared and
3163 private parts: shared close is called by the daemon.
3165 * handles.c: As above, but also pass handle allocation, ref and
3166 unref operations to the daemon. Populate the handle_ops array at
3167 compile time, because the daemon needs to call ops on handles too.
3168 Don't bother to track open handle counts any more, the daemon does
3172 * thread-private.h: As above, but also make the thread data
3175 * shared.c: Fork a handle daemon if the calling process created
3176 the shared memory segment.
3179 * daemon-messages.c:
3180 * daemon-messages.h:
3181 * Makefile.am: Build a daemon to manage handle allocation and
3182 destruction without needing to lock the shared memory
3184 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
3186 * atomic.c: Changed to use a normal mutex rather than a spinlock
3187 since a lot of platforms seem to not have them :\
3189 2002-04-30 Dick Porter <dick@ximian.com>
3191 * Completely rewrote the handle waiting code: removed the helper
3192 thread and its attendant complexity. All handle waiting is now
3193 abstracted into the WaitForSingleObject() and
3194 WaitForMultipleObjects() functions.
3196 * Implemented inter-process sharing of handles using sysv shared
3197 memory. This makes handles even more opaque, with a handle now
3198 just an index into an array.
3200 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
3202 * io.c: unitialized pointer in GetCurrentDirectory.
3204 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
3206 * threads.c: destroy the mutex at thread destruction
3207 (if/when thread destruction code will be actually called).

3239 * io.c: EEXISTS is ignored for directory creation.
3240 * mono-mutex.h: remove silly "pragma }" that emacs users insert

3286 2002-03-22 Dick Porter <dick@ximian.com>
3288 * threads.c: Fix a race condition where a thread can start and
3289 exit before the handle has been properly initialised (no reason
3290 why the handle couldn't be initialised beforehand, so do so)

3294 2002-03-21 Dick Porter <dick@ximian.com>
3296 * semaphores.c: Fix a problem when waiting for one or more
