220 unpleasant feature in g_shell_parse_argv() where it treats '#'
221 embedded in a filename as a comment marker, and throws away the
222 rest of the line. When we're directly opening URLs quote the
223 filename, to avoid this. Fixes bug 371567.

241 * io-layer.h: Removed Windows version macros.
243 Thu Mar 13 16:24:53 CET 2008 Paolo Molaro <lupus@ximian.com>

253 part of module name is equal to the process name.
255 * processes.c (EnumProcessModules) : Changed the first entry in the returned
256 modules array (the process module) to be populated from the entry found
259 * processes.c (get_module_name & GetModuleInformation) : In the case where
260 the module passed in is NULL, search the /proc/<PID>/maps for a name that
261 matches the process name to populate the return information.
265 2008-01-29 Zoltan Varga <vargaz@gmail.com>
267 * security.c (RevertToSelf): Make this return TRUE if impersonating is not
270 * sockets.c (_wapi_connect): Add a workaround to a solaris x86 problem where

288 * threads.c (_wapi_thread_set_termination_details): Move the

300 work on big-endian systems.
301 (scan_resource_dir): Copy the resource directory entry and
302 byteswap if necessary so it works big-endian. This fixes bug
303 345972 for real this time.
304 (VerQueryValue): String values set the length to the number of
305 unicode chars, but the data length reported was already correct so
306 don't halve it again. Fixes the previous fix for bug 345972.
307 (GetFileVersionInfo): On big-endian systems, scan the resource
308 data and turn all unicode strings into UTF-16BE. FileVersionInfo
309 now works big-endian.
311 2008-01-04 Dick Porter <dick@ximian.com>
313 * versioninfo.c (VerQueryValue): Returned buffer length counts
314 chars not bytes for string data. Fixes bug 345972 again.
315 (get_enclosing_section_header): Make sure values read are treated
316 as LE. Fixes crash on ppc reported in bug 345972.
318 2007-12-17 Mark Probst <mark.probst@gmail.com>

360 (EnumProcessModules): Don't miss the first module returned by
363 2007-11-15 Dick Porter <dick@ximian.com>
365 * processes.c: Implement process module support by reading from
366 /proc if it's available.

382 2007-10-26 Dick Porter <dick@ximian.com>
384 * shared.c (_wapi_shm_file_open): Set the umask when opening
385 shared files, so restrictive defaults don't prevent subsequent
386 processes re-opening them.
388 2007-10-18 Zoltan Varga <vargaz@gmail.com>
390 * atomic.h (InterlockedCompareExchange): Fix the ia64 version so it works for

401 * io-portability.c: options_init moved to
402 utils/mono-io-portability.c
403 Do not initialize portability helpers here, it's done in

531 2007-06-13 Dick Porter <dick@ximian.com>
533 * handles.c (timedwait_signal_wait_cond): Alertable waits on
534 private handles are now interrupted by signalling the same

563 2007-05-10 Dick Porter <dick@ximian.com>
565 * sockets.c (_wapi_recvfrom): Refine the fix to bug 75705 so EINTR

633 * io.c (CreateFile): Use FILE_ATTRIBUTE_TEMPORARY to mean 0600
634 permissions. For 80688
636 (MoveFile): Use errno_copy here, just to avoid a potential
637 errno-changing code in the future from g_free.
639 Also, ignore EXDEV errors as they are handled immediately after
640 (avoid printing out an error).
644 Mon Feb 12 15:50:24 CET 2007 Paolo Molaro <lupus@ximian.com>
646 * shared.c: exit if semaphores can't be created (bug #80616).
648 2007-02-01 Geoff Norton <gnorton@customerdna.com>
650 * collection.c: NetBSD doesn't define PTHREAD_STACK_MIN.
652 2007-01-26 Dick Porter <dick@ximian.com>
655 * sockets.c (_wapi_getsockopt): Windows seems to not reset
656 SO_ERROR values when they're read, contrary to the documentation.
657 Fixes the new issues raised in bug 79878 (example in C showing
658 winsock behaviour attached to that bug.)
660 2007-01-15 Mark Mason <mason@broadcom.com
662 * atomic.h: add locking primitives for MIPS.
664 2007-01-11 Dick Porter <dick@ximian.com>
666 * sockets.c (_wapi_connect): Don't do the SO_BROADCAST setting
667 here, do it in managed code instead.
668 (_wapi_getsockopt): SO_RCVTIMEO and SO_SNDTIMEO use struct
669 timeval, which has a microsecond field, not milliseconds.
670 (_wapi_setsockopt): ditto.
671 (_wapi_setsockopt): Halve the SO_SNDBUF and SO_RCVBUF values on
672 Linux, as the kernel doubles whatever we set.
673 (_wapi_socket): Save socket domain, type and protocol so it can be
675 (socket_disconnect): Implement socket disconnect (closing the
676 socket, but keeping the file descriptor.)
677 (wapi_disconnectex): A basic implementation of DisconnectEx().
678 (wapi_transmitfile): A very basic implementation of
680 (WSAIoctl): Implement the SIO_GET_EXTENSION_FUNCTION_POINTER
683 * socket-private.h (struct _WapiHandle_socket): Record socket
684 domain, type and protocol info so it can be duplicated later.
686 * sockets.h (WSAID_DISCONNECTEX,WSAID_TRANSMITFILE): Structures
687 and defines needed to look up the DisconnectEx() and
688 TransmitFile() functions by GUID.
690 * error.c (errno_to_WSA): Change ETIMEDOUT mapping to
691 WSAETIMEDOUT; add EDESTADDRREQ.
693 * io-layer.h: Need mswsock.h on windows now.
695 2007-01-04 Miguel de Icaza <miguel@novell.com>
697 * io-portability.c (find_file): Fix a coverity warning (scanning
700 2006-12-31 Miguel de Icaza <miguel@novell.com>
702 * io-portability.c (find_file): Do not abort if an empty filename
703 has been passed. This fixes the case where MONO_IOMAP=all would
704 assert if Directory.Exists ("") was called.
706 Mon Dec 18 14:54:37 CET 2006 Paolo Molaro <lupus@ximian.com>
708 * processes.c: moved a free on the error path.
710 Thu Dec 14 21:42:39 CET 2006 Paolo Molaro <lupus@ximian.com>
712 * processes.c: fixed a few memory leaks when executing
715 Mon Nov 27 13:12:17 GMT 2006 Paolo Molaro <lupus@ximian.com>
717 * atomic.h: fix arm compare and exchange (bug #78500).
719 2006-11-23 Dick Porter <dick@ximian.com>
721 * process-private.h (struct _WapiHandle_process): Add 'waited'
724 * processes.c (process_wait): Check the 'waited' parameter not the
725 signalled state when testing if a process has already been waited
726 for, as the child process itself may set signalled when exiting.
729 * wapi-private.h (_WAPI_HANDLE_VERSION): Bump shared data version
731 * shared.c: Now the shared data version has been incremented we
732 can set the counter semaphore initial value correctly
734 2006-11-22 Dick Porter <dick@ximian.com>
736 * processes.c (process_wait): Cope when the background process
737 reaper gets the process we were waiting for. Special case for
738 waiting for our own process to exit. Fixes bug 77736.
740 2006-11-17 Dick Porter <dick@ximian.com>
742 * processes.c: Fix const correctness and typos that caused memory
745 2006-11-17 Miguel de Icaza <miguel@novell.com>
747 * processes.c (ShellExecuteEx): Check error after CreateProcess,
748 thanks to Dick for pointing this out.
750 2006-11-16 Miguel de Icaza <miguel@novell.com>
752 * processes.c (ShellExecuteEx): If we fail to create a process in
753 ShellExecute, then try to use the xdg-open command, and if that
754 fails, try to use the gnome-open command,
756 Refactor the code so that we do not have to duplicate all this
757 code, but instead use a ucs2-aware version of the code to do
760 2006-11-13 Dick Porter <dick@ximian.com>
762 * io.c (_wapi_stat_to_file_attributes): If the file is a symlink
763 add the FILE_ATTRIBUTE_REPARSE_POINT flag. This is an attempt to
764 follow the specs for the windows symlink support, but will
765 probably have to be reworked when I have test data from a vista
766 machine. Fixes bug 79887.
768 2006-11-11 Miguel de Icaza <miguel@novell.com>
770 * handles.c (CloseHandle): Cope here with the new value
771 INVALID_HANDLE_VALUE set on handles.
773 * processes.c (CreateProcess): Initialize the value of hThread to
774 be INVALID_HANDLE_VALUE on failure, not to be NULL. Improvement
777 2006-11-09 Dick Porter <dick@ximian.com>
779 * sockets.c (_wapi_select): Do some sanity checking on the
780 fd_sets, to avoid file descriptors > FD_SETSIZE.
781 (_wapi_FD_CLR, _wapi_FD_ISSET, _wapi_FD_SET): Avoid file
782 descriptors > FD_SETSIZE.
784 2006-10-27 Dick Porter <dick@ximian.com>
786 * io.c (GetFileAttributes): Force symlinks to directories to be
787 returned as a regular file. Fixes bug 79733.
789 2006-10-18 Miguel de Icaza <miguel@novell.com>
791 * io-portability.c (find_in_dir): First string dup, then closedir.
793 2006-10-12 Dick Porter <dick@ximian.com>
795 * processes.c (_wapi_process_reap): Unref a process handle if we
796 reaped it, found by Zoltan. Fixes bug 79286.
797 (process_wait): Don't wait again if we've already waited for a
800 2006-10-11 Sergey Tikhonov <tsv@solvo.ru>
802 * atomic.h: Fix atomic decrement.
804 * mini/cpu-alpha.md: Use native long shift insts
806 * mono/mono/mini/tramp-alpha.c: Implemented
807 mono_arch_patch_delegate_trampoline method
809 * Started work on using global registers
811 * Use byte/word memory load/store insts if cpu supports it
816 2006-10-09 Zoltan Varga <vargaz@gmail.com>
818 * handles.c (timedwait_signal_poll_cond): Add an alertable parameter, and if it
819 is FALSE, avoid busy waiting.
821 * wait.c: Add an alertable parameter to the wait routines.
823 2006-10-06 Miguel de Icaza <miguel@novell.com>
825 * io-portability.c (find_file): Rename from
826 MONO_IO_PORTABILITY_HELP to MONO_IOMAP.
828 2006-10-03 Dick Porter <dick@ximian.com>
831 * io-portability.c: Optional portability helpers and wrapped
832 system calls to try to cope with windows filenames in
835 * io.c: Use the wrapped system calls
837 2006-09-01 Zoltan Varga <vargaz@gmail.com>
839 * critical-sections.h critical-sections.c: Make Enter/LeaveCriticalSection a macro
840 since they are perf critical.
842 * atomic.h: Applied patch from Jakub Boqusz <qboosh@pld-linux.org>.
843 Add atomic ops implementation for alpha.
845 2006-08-11 Dick Porter <dick@ximian.com>
847 * processes.c (_wapi_process_reap): Avoid a deadlock by setting
848 process termination details in an outer loop, not the
849 _wapi_search_handle() one.
851 2006-08-10 Dick Porter <dick@ximian.com>
853 * threads.c (_wapi_thread_queue_apc)
854 (_wapi_thread_dispatch_apc_queue): Use a process-local mutex here
855 instead of the cross process semaphore. We already check that
856 access to the APC queue is within the owning process so there's no
857 need to protect from other processes. Avoids a global deadlock
858 when a thread is aborted while it holds the handle semaphore
860 (_wapi_thread_apc_pending): Hide an annoying message which can
861 happen if a thread handle has been blown away at process shutdown
862 while it is in an alertable wait.
864 Both problems seen while shutting down monodevelop.
866 2006-07-25 Dick Porter <dick@ximian.com>
868 * shared.c (_wapi_shm_file): Remove '/' characters from the uname
869 results. Fixes bug 78917.
871 2006-07-20 Dick Porter <dick@ximian.com>
873 * threads.c (_wapi_thread_set_termination_details): Improve the
874 test for already-disposed thread handles, and hold the lock around
875 the mutex abandoning.
877 2006-07-17 Dick Porter <dick@ximian.com>
879 * processes.c (CreateProcess): Don't change directory unless a new
880 one has been specified. Fixes bug 78751.
882 2006-07-06 Dick Porter <dick@ximian.com>
884 * io.c (_wapi_stat_to_file_attributes): Do a better job at
885 figuring out the file attributes
886 (_wapi_set_last_path_error_from_errno): New helper function to
887 turn errno into w32 error codes that handles the differences
888 between file and directory errors
889 (file_setendoffile): Try turning off the extra write used to
890 extend files, because we probably don't need it on any modern
891 platform. If it is needed though, we also need to lseek the file
893 (CreateFile): Treat character-special devices as a console handle,
894 because they can't be seeked
895 (CopyFile): If fail_if_exists is set, then the destination needs
896 to be opened with O_EXCL
897 (CopyFile): If fail_if_exists is not set and the destination
898 already exists, then we should set the ERROR_ALREADY_EXISTS error
899 even though we return success
900 (stdhandle_create): STD_INPUT_HANDLES cannot be written to
901 (GetStdHandle): Rework without using mono_once, so console handles
902 can be properly closed and reopened.
903 (mono_io_scandir): Only override errno with EACCES when the
904 directory actually exists
905 (FindFirstFile): Set ERROR_FILE_NOT_FOUND when no files are
907 (FindClose): Cope with NULL handles
908 (CreateDirectory): When the target already exists, just return an
909 error. It's the caller's job to figure out what to do.
910 (SetCurrentDirectory): Cope with a NULL path
911 (RemoveDirectory, GetFileAttributes, GetFileAttributesEx,
912 SetFileAttributes, FindFirstFile, DeleteFile, MoveFile, CopyFile,
913 CreateFile): Set path error correctly
915 * handles.c (CloseHandle): Kludge to try and cope with passing a
918 * error.h: Add NO_ERROR as an alternative to ERROR_SUCCESS
920 * uglify.h: Added some more typedefs
922 2006-07-05 Dick Porter <dick@ximian.com>
924 * io.c (GetFileAttributes, GetFileAttributesEx): Cope with
925 dangling symlinks. Fixes bug 78664.
927 2006-06-23 Dick Porter <dick@ximian.com>
929 * handles.c (handle_cleanup):
930 * threads.c: Clean up threads properly when we're forcibly
931 removing the handle entries from the shared file in
932 handle_cleanup(). Fixes bug 78241, for real this time.
934 2006-06-15 Neale Ferguson <neale@sinenomine.net>
936 * atomic.h: More tinkering with InterlockedExchange/InterlockedCompareExchange
939 2006-06-14 Neale Ferguson <neale@sinenomine.net>
941 * atomic.h: Fix atomic exchange pointer operations for s390x - these
942 were broken as they used 32-bit instructions rather than their 64-bit
945 2006-06-14 Dick Porter <dick@ximian.com>
947 * processes.c: Don't run the atexit handlers when bailing out
950 2006-06-14 Dick Porter <dick@ximian.com>
952 * wait.c: Fix stupid typo shown up by gcc 4.1.1, = not ==
960 * collection.c: Fix a bunch of signed/unsigned warnings from gcc
963 2006-06-09 Neale Ferguson <neale@sinenomine.net>
965 * atomic.h: Fix atomic operations for s390x (not really broken
966 but changed to use full 64-bit opcodes).
968 2006-05-24 Dick Porter <dick@ximian.com>
970 * processes.c (process_set_current): Don't take an extra reference
971 if we have to create our own process handle. Fixes bug 78241
974 * threads.c (_wapi_thread_signal_self): Renamed from
975 _wapi_thread_abandon_mutexes, also sets the thread state to
976 signalled and drops a reference. Called by the runtime when the
977 main thread cleans itself up.
979 * handles.c (handle_cleanup): As a last resort, unref every shared
980 handle as the process is now exiting.
982 2006-05-16 Dick Porter <dick@ximian.com>
984 * processes.c (process_set_termination_details): Unref the handle
985 when we've stored the exit details. Fixes the rest of 78241.
987 2006-05-12 Dick Porter <dick@ximian.com>
989 * threads.c: Implement pseudo handles, making GetCurrentThread()
990 match MS behaviour. Notice when attached threads exit, and unref
991 the handle. Fix usage of GetCurrentThread() in other places.
993 * handles.c (DuplicateHandle): Implement a basic form of
996 * wait.c: Fix usage of GetCurrentThread() throughout, and cope
999 2006-04-26 Miguel de Icaza <miguel@novell.com>
1001 * io.c (file_close): Oops, do not use DeleteFile which expects
1002 unicode, instead use unlink directly
1004 Add support for the new FileOptions bits on .NET 2.0.
1006 It might be good if Dick reviews these changes.
1008 * io.c (file_close): If DeleteOnClose is set, then delete the file
1010 (CreateFile): Do not support encryption per user.
1012 If posix_fadvise exists, pass hints on sequential scan and random
1013 access. Did not figure out what WRITE_THROUGH maps to.
1015 2006-04-26 Dick Porter <dick@ximian.com>
1017 * sockets.c (WSAIoctl): Check the output buffer is valid before
1020 * handles.c (_wapi_search_handle): Set shared pointer if we find a
1021 shared handle that has been already opened.
1023 2006-04-21 Dick Porter <dick@ximian.com>
1025 * threads.c (GetCurrentThread): Reference the handle if we return
1026 an already-known thread.
1028 2006-04-07 Dick Porter <dick@ximian.com>
1030 * processes.c: Fix build for older glib.
1032 2006-04-06 Dick Porter <dick@ximian.com>
1034 * processes.c (CreateProcess): Add a reference to the child
1035 process' handle, so it won't be destroyed if this process closes
1036 its copy of the handle. Fixes bug 77393.
1038 * processes.c (process_set_current): Fall through to creating a
1039 new one if the handle lookup fails.
1041 * processes.c (_wapi_process_signal_self):
1042 * handles.c (handle_cleanup): The process is exiting, so set the
1043 handle state for this process to signalled. This should let other
1044 non-related processes wait for this handle.
1046 * handles.c (_wapi_search_handle): Don't search shared handles in
1049 * collection.c (collection_thread): No need to do a collection
1050 scan straight away, do the waiting first.
1052 2006-04-06 Dick Porter <dick@ximian.com>
1054 * shared.c: Fix parameters in semctl () call.
1056 2006-03-28 Zoltan Varga <vargaz@gmail.com>
1058 * atomic.h atomic.c: Applied patch from David S. Miller
1059 <davem@davemloft.net>: Reimplement Interlocked* primitives on sparc
1060 using CAS/CASx when __GNUC__, else we will fall back to the generic
1063 2006-03-27 Dick Porter <dick@ximian.com>
1065 * shared.c (_wapi_shm_file_open): Break out of a loop if the
1066 shared file is smaller than expected. (We loop a few times in
1067 case another process is in the middle of creating the file.)
1069 2006-03-22 Dick Porter <dick@ximian.com>
1074 * shared.c: Delete the semaphores and shared files when the last
1075 process has finished with them
1077 2006-03-15 Dick Porter <dick@ximian.com>
1085 * threads.c: Explicitly initialise the handle ops struct
1087 2006-03-14 Dick Porter <dick@ximian.com>
1089 * handles-private.h:
1092 * handles.c: Add a 'prewait' stage to the handle waiting, to give
1093 waiting threads a chance to check for bogus states before
1096 * mutexes.c (namedmutex_prewait): Use the prewait stage to check
1097 for named mutexes that have been abandoned in a locked state (eg
1098 if a process exited abnormally while owning the mutex) and
1099 override it if needed.
1101 2006-03-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1103 * wait.c: speed up WaitFor* when the timeout is 0.
1105 2006-03-03 Dick Porter <dick@ximian.com>
1107 * processes.c (ShellExecuteEx): Cope when some of the parameters
1110 2006-02-27 Dick Porter <dick@ximian.com>
1114 * threads.c: Comparing pthread_t with == is not portable, so use
1117 Thu Feb 23 18:47:20 GMT 2006 Paolo Molaro <lupus@ximian.com>
1119 * *.h, *.h: patch from Dick to make Linuxthreads systems work again.
1121 2006-02-22 Dick Porter <dick@ximian.com>
1124 * threads.c: There's no need to use the timed-thread support code
1125 any more, as we aren't using the timed join. This greatly
1126 simplifies thread setup, and fixes a memory leak (bug 77521).
1128 Don't bother to store thread IDs in a hash table, use TLS instead.
1129 The one case that needs to look up the handle of a different
1130 thread (OpenThread()) can do the extra work itself. Fixes bug
1133 * handles.c (_wapi_search_handle): Add a reference when returning
1134 a private handle (shared handles are already reffed.)
1136 2006-02-17 Dick Porter <dick@ximian.com>
1138 * handles-private.h:
1139 * handles.c: Check handle values passed to array lookups. Fixes
1142 2006-02-09 Dick Porter <dick@ximian.com>
1144 * threads.c: Cope with the problems caused by attaching already
1145 existing threads - they don't get the infrastructure to clean up
1146 after themselves, especially the ID to handle hash. This fixes
1149 2006-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1151 * shared.c: use MONO_SHARED_HOSTNAME as a substitute for gethostname()
1152 when creating the shared files in the .wapi directory. Fixes bug #77371.
1154 2006-02-02 Martin Baulig <martin@ximian.com>
1156 * threads.c: Removed the `WITH_INCLUDED_LIBGC' section; it has
1157 never been used so far.
1159 * timed-thread.h (TimedThread): Removed the `stack_ptr' field; it
1160 has only been used by the removed code.
1162 2006-01-03 Neale Ferguson <neale@sinenomine.net>
1164 * atomic.h: Correct s390x definitions and eliminate compiler warnings.
1166 2006-01-03 Sebastien Pouliot <sebastien@ximian.com>
1168 * io.c: Patch _wapi_stat_to_file_attributes against bug #76966, where
1169 sockets could be considered as directory.
1171 2005-12-23 Dick Porter <dick@ximian.com>
1175 * semaphores.c: Implement OpenSemaphore
1178 * mutexes.h: Implement OpenMutex
1184 * event-private.h: Implement named events. Implement OpenEvent.
1186 2005-12-15 Dick Porter <dick@ximian.com>
1188 * processes.c (CreateProcess): The pipe-based cross-process
1189 exclusion technique was trying to write NULL buffers when appname
1190 was NULL (eg when coming from ShellExecuteEx,) which usually
1191 succeeded even though EFAULT was returned - but sometimes it
1192 failed. This meant that the child process could block forever on
1193 the pipe read. Replace it with the simpler shared handle
1194 semaphore protection used everywhere else. This showed up with
1195 the test case in bug 76684.
1197 Tue Dec 13 11:41:49 GMT 2005 Paolo Molaro <lupus@ximian.com>
1199 * shared.c: fallback to private mmap when shared mmap doesn't work
1202 2005-12-06 Dick Porter <dick@ximian.com>
1206 * semaphore-private.h:
1207 * semaphores.c: Implement named semaphores
1209 2005-11-24 Dick Porter <dick@ximian.com>
1211 * processes.c (GetProcessId): Implement GetProcessId()
1213 2005-11-17 Dick Porter <dick@ximian.com>
1216 * processes.c: Implement ShellExecuteEx as a wrapper around
1219 2005-11-11 Dick Porter <dick@ximian.com>
1221 * threads.c: Give mutex abandoning its own exported function, so
1222 it can be called when the runtime is cleaning up.
1224 * handles.c (_wapi_search_handle_namespace): Do a handle
1225 collection befre starting to check namespace strings, so that any
1226 stale cruft gets removed.
1228 2005-11-11 Dick Porter <dick@ximian.com>
1230 * threads.c: Move thread handles back into the shared space.
1232 * handles.c (_wapi_handle_unref): Add support for shared handles
1233 with close() handlers
1235 2005-11-04 Dick Porter <dick@ximian.com>
1237 * sockets.c (ioctlsocket): Use select instead of if to avoid a
1238 type promotion problem on 64bit freebsd. Based on patch by Lou
1239 Kamenov <kamenovl@gmail.com>, fixes bug 76447.
1241 2005-11-04 Dick Porter <dick@ximian.com>
1243 * io.c (file_write): Only do the file locking if
1244 MONO_STRICT_IO_EMULATION is set.
1246 2005-10-21 Dick Porter <dick@ximian.com>
1249 * handles.c (_wapi_lookup_handle): Cope when the shared part of a
1250 handle has been deleted.
1251 (_wapi_handle_unref): And when the deleted shared part is pointed
1252 to as a handle is deleted
1254 2005-10-20 Dick Porter <dick@ximian.com>
1256 * processes.c (process_set_current): If the expected process
1257 handle slot doesn't contain the correct pid, create a new handle.
1259 * handles.c (_wapi_search_handle): When the search doesn't find
1260 anything, return failure instead of the last handle we looked at.
1261 (_wapi_handle_ref, _wapi_handle_unref): Don't try to ref or unref
1262 unused handles (makes tracking refcounting bugs easier.)
1264 2005-10-19 Dick Porter <dick@ximian.com>
1267 * handles-private.h:
1271 * collection.c (_wapi_handle_collect): Remove the shared handle
1272 indirection layer, and use locking instead. Delete other
1273 complexity that is no longer needed. Refcount shared handles and
1274 delete them when needed, but keep the timestamps so that orphaned
1275 handles will be cleaned up eventually.
1277 * shared.c (_wapi_shm_file): Add processor, OS and struct size
1278 info to the shared file names, to cope with dual-boot and 32/64bit
1279 size issues. Fixes bug 75839.
1281 * wait.c (WaitForMultipleObjectsEx): No need to distinguish
1282 between shared handles and private, as the wait functions cope
1283 with both together now.
1285 2005-10-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1287 * io.c: removed NO_SIGPIPE macro.
1288 * sockets.c: no need for MSG_NOSIGNAL or ignoring SIGPIPE.
1290 2005-10-11 Dick Porter <dick@ximian.com>
1292 * sockets.c (_wapi_getsockopt): Translate SO_ERROR results into
1295 * error.c (errno_to_WSA): Don't return a bogus error if someone
1296 asks to translate errno 0.
1298 2005-10-11 Dick Porter <dick@ximian.com>
1300 * handles.c: Fix several race conditions
1302 2005-10-11 Miguel de Icaza <miguel@novell.com>
1304 * io.c: no need to block SIGPIPE anymore, as it is ignored.
1306 2005-10-05 Dick Porter <dick@ximian.com>
1308 * threads.c (_wapi_thread_own_mutex, _wapi_thread_disown_mutex):
1309 Keep a reference to mutexes owned by threads, so they won't be
1310 destroyed prematurely. Fixes dotmsnclient crash.
1312 2005-09-26 Sebastien Pouliot <sebastien@ximian.com>
1314 * io.c: Apply patch from #76192 (Can't write files past 2gb on AMD64
1315 (x86_64)) for Brion on IRC (Dick approved it).
1317 2005-09-23 Dick Porter <dick@ximian.com>
1319 * processes.c: Don't wait for processes that have already been
1320 signalled; also fix typo.
1322 * handles.c: Improve locking inside new handle and handle
1323 searching functions.
1325 2005-09-20 Dick Porter <dick@ximian.com>
1328 * processes.c: Periodically waitpid for known process IDs. Fixes
1331 2005-09-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1334 (CreateFile): if the file is a named pipe, treat the handle as a pipe,
1335 not as a file. Fixes bug #76075.
1337 2005-08-27 Zoltan Varga <vargaz@gmail.com>
1339 * atomic.h: Add support for intel icc.
1341 2005-08-25 Zoltan Varga <vargaz@gmail.com>
1343 * io-layer.h: Include winbase.h not WinBase.h.
1345 2005-08-19 Dick Porter <dick@ximian.com>
1347 * threads.c, threads.h, thread-private.h: Use a gsize to store the
1348 thread ID, so it can hold a 64 bit value if needed.
1350 2005-07-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1352 * error.c: map ENOENT to WSAECONNREFUSED. It might happen when
1353 connecting to unix sockets. Closes bug #75632.
1355 2005-07-05 Dick Porter <dick@ximian.com>
1357 * io.c: Make sure SIGPIPE is ignored when calling write(2).
1358 Prevents the runtime exiting when writing to a closed pipe,
1361 2005-06-30 Dick Porter <dick@ximian.com>
1363 * shared.c (_wapi_shm_semaphores_init): Add some helpful error
1364 messages when semget () fails due to lack of resources.
1366 2005-06-21 Dick Porter <dick@ximian.com>
1371 * threads.c: Keep a list of owned mutexes in each thread handle,
1372 so that it is easier to abandon them when the thread exits.
1373 Removes a bottleneck when multiple threads are finishing in
1376 2005-06-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1378 * io.c: (GetLogicalDrives) when a bogus line is read, don't leak memory.
1379 When the buffer has not enough space, close the file before returning.
1381 2005-06-09 Duncan Mak <duncan@novell.com>
1383 * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to
1384 all public headers. Fixes #74919.
1386 2005-05-30 Zoltan Varga <vargaz@freemail.hu>
1388 * atomic.h: Add IA64 atomic ops.
1390 2005-05-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1392 * processes.c: make ExitCode be valid even if the user didn't call
1393 WaitForExit() and is just polling on HasExited.
1395 2005-05-17 Dick Porter <dick@ximian.com>
1397 * io.c (file_getfilesize): Clear the error value, so that files
1398 with sizes with the low bits 0xFFFFFFFF can be distinguished from
1401 2005-05-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1403 * shared.c: forgot to ignore a warning.
1405 2005-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1407 * shared.c: don't display warnings after reboots.
1409 2005-05-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1411 * sockets.c: on windows, getsockopt/setsockopt for send/receive timeout
1412 use an integer in milliseconds. We were using a struct timeval.
1414 2005-05-06 Dick Porter <dick@ximian.com>
1416 * handles-private.h:
1423 * collection.h: Use SysV semaphores for managing access to the
1424 shared memory - in return for the ludicrous api we get
1425 synchronisation primitives that can be cleaned up by the kernel
1426 even when a process quits unexpectedly. This removes the
1429 2005-05-05 Lluis Sanchez Gual <lluis@novell.com>
1431 * handles.c: Always use polling in the waits, since
1432 mono_cond_timedwait can't be interruped by the thread abort signal.
1434 2005-04-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1436 * events.c: calling Set on AutoResetEvent several times has the same
1437 effect as calling it only once if no thread is waiting for it.
1439 2005-04-29 Dick Porter <dick@ximian.com>
1441 * processes.c (EnumProcesses): Use a GArray instead of a GPtrArray
1442 now it's storing pids not handles, also fixes memory leak caused
1443 by unclear glib documentation.
1445 * sockets.c (WSACleanup): Remove unused variable
1447 2005-04-29 Dick Porter <dick@ximian.com>
1449 * handles.c (_wapi_handle_check_share_by_pid): For systems that
1450 don't have file descriptor info in /proc check that the original
1451 opener of a file is still there, if a share violation would
1454 2005-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1457 * handles-private.h: added _wapi_handle_forecch that loops through all
1458 the handles and call a callback function when a handle of the given
1461 * sockets.c: no need to keep open sockets in an array, as we have them
1462 in the handles structure.
1466 2005-04-28 Dick Porter <dick@ximian.com>
1468 * processes.c: Cope with handles that are only around for as long
1469 as the search is running. If we're searching for process handles,
1470 check to see if the process is still running and signal it if not.
1472 * handles.c (_wapi_search_handle): Search in the shared space as
1473 well. Fixed bug 74752.
1476 * handles.c (_wapi_handle_new_from_offset):
1477 _wapi_handle_new_for_existing_ns () was doing exactly the same as
1478 this, so deleted it.
1480 2005-04-26 Dick Porter <dick@ximian.com>
1482 * handles.c: Fix stupid thinko where if a new shared handle is
1483 created but a collection was needed to free some space, it
1484 returned an error anyway. Should fix the messages shown in bug
1487 2005-04-25 Dick Porter <dick@ximian.com>
1489 * handles.c (_wapi_handle_check_share): Only consider mono
1490 processes when looking to see if a file is still being held open,
1491 while checking share permissions.
1493 2005-04-25 Dick Porter <dick@ximian.com>
1497 * wapi-private.h (struct _WapiHandleOps):
1498 * handles.c (_wapi_handle_unref): When destroying handles, save
1499 the handle data and call the close function only after the array
1500 slot has been cleared. This prevents race conditions with file
1501 descriptors, fixing bug 74713.
1503 * mutexes.c: Delete the handle close functions, they didn't do
1506 * error.c (_wapi_get_win32_file_error): Add a mapping for EINTR so
1507 the "Unknown error" g_warning doesn't get displayed.
1509 2005-04-25 Dick Porter <dick@ximian.com>
1512 * threads.c: Make thread handles process-private for now to take
1513 some of the space pressure off the shared memory, while I work on
1516 2005-04-21 Dick Porter <dick@ximian.com>
1518 * handles.c (_wapi_handle_check_share): Make sure there is a "fd"
1519 dir in /proc before blowing away handle info. Fixes bug 74649.
1521 2005-04-21 Dick Porter <dick@ximian.com>
1523 * wait.c (WaitForMultipleObjectsEx): Implement special waits
1525 * handles.c (_wapi_handle_wait_signal_poll_share): Don't return a
1526 timeout, just wait briefly for the private signals and let the
1527 waiting thread test again. This prevents us missing shared
1530 2005-04-21 Dick Porter <dick@ximian.com>
1532 * collection.h (_WAPI_HANDLE_COLLECTION_EXPIRED_INTERVAL): Reduce
1533 the time before a slot is considered too old and deleted. This is
1534 a workaround while I come up with a proper fix.
1536 2005-04-21 Dick Porter <dick@ximian.com>
1541 * handles.c (_wapi_handle_new): Turn assertions into errors.
1543 * collection.c (_wapi_handle_collect): Use symbols not magic
1544 numbers for timeout values
1546 2005-04-19 Dick Porter <dick@ximian.com>
1550 * handles.c (_wapi_handle_count_signalled_handles)
1551 * handles-private.h (_wapi_handle_shared_lock_handle): Use new
1552 shared handle locks in critical sections.
1554 * handles.c (_wapi_handle_new_for_existing_ns): Reuse old handles
1555 if there is already one there.
1557 * handles.c (_wapi_handle_ref): It was possible for a process to
1558 exit before getting around to updating shared handle timestamps,
1561 Tue Apr 19 16:25:47 CEST 2005 Paolo Molaro <lupus@ximian.com>
1563 * threads.c: fix lookup of the thread id in the has table:
1564 always use the id value, not the pointer to the id.
1566 2005-04-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1568 * handles.c: fix handle returned in _wapi_handle_search_handle. Dick
1571 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1573 * io-layer/sockets.c: FIONBIO with a TRUE argument means we want
1574 non-blocking IO, not the other way around.
1576 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1580 * handles-private.h: GetFileType wasn't checking if we have memory
1581 allocated for the handle before dereferencing it. Fixes a FileStream
1584 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1588 * handles-private.h: we were calling g_renew to expand the handle array,
1589 but that might move the memory and we might have pthread conditions or
1590 mutexes in the original memory area that are being used. Now instead of
1591 expanding an existing array, we just create new ones and keep a list of
1592 them. Access to _wapi_private_handles had to be modified accordingly.
1594 2005-04-15 Dick Porter <dick@ximian.com>
1596 * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN
1598 2005-04-14 Raja R Harinath <rharinath@novell.com>
1600 * wapi-private.h: Remove reference to 'daemon-private.h'.
1602 Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro <lupus@ximian.com>
1604 * atomic.h: applied patch from mass@akuma.org (David Waite)
1605 to fix InterlockedExchangeAdd.
1606 Fixed a few other functions, including InterlockedCompareExchange()
1607 which was miscompiled by gcc with optimizations enabled.
1609 2005-04-13 Dick Porter <dick@ximian.com>
1611 * io.c (share_check):
1612 * handles.c (_wapi_handle_check_share): Refine the file check so
1613 that sharing violations within the same process don't cause
1616 2005-04-13 Dick Porter <dick@ximian.com>
1618 * io.c (FindFirstFile): Fix bugs introduced with the merge (bug
1621 2005-04-12 Dick Porter <dick@ximian.com>
1623 The daemon-less io-layer. Extensive lowlevel changes in
1624 handles.c, requiring some corresponding changes in other files
1625 calling these functions. Private_foo structures have been
1628 File descriptor handling differences account for most of the
1629 changes in io.c and sockets.c.
1633 * mutexes.c: Named mutexes are now a distinct type.
1634 * atomic.h: Fix a PPC uninitialised variable warning.
1635 * wait.c: Check conditions before waiting on a condition variable.
1636 * processes.c: Handle process fork and wait without a daemon
1637 (though this has the limitation of only being able to wait for
1640 2005-04-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1647 * sockets.h: removed dead code that deals with async IO.
1649 2005-03-30 Zoltan Varga <vargaz@freemail.hu>
1651 * atomic.c (InterlockedIncrement): Fix fallback implementation of
1652 InterlockedIncrement and InterlockedDecrement. Fixes #74228.
1654 2005-03-29 Sebastien Pouliot <sebastien@ximian.com>
1656 * io-layer.h: Add required header files for compiling with VS.NET.
1658 2005-03-17 Miguel de Icaza <miguel@novell.com>
1660 * io.c: don't fail on NFS when there are no more locks available.
1662 2005-03-09 Dick Porter <dick@ximian.com>
1664 * error.c (_wapi_get_win32_file_error): ENFILE and EMFILE should
1665 map to ERROR_TOO_MANY_OPEN_FILES, not ERROR_NO_MORE_FILES. Fixes
1668 2005-03-09 Dick Porter <dick@ximian.com>
1670 * daemon.c (process_process_fork): Initialise the handle data
1671 before using it in the error case. This is probably the error
1672 we're working around in the previous change. Spotted by Taru Jain
1673 <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.
1675 2005-03-07 Dick Porter <dick@ximian.com>
1677 * daemon.c: It looks like g_shell_parse_argv() can return
1678 argv[0]=NULL somehow, yet still not give an error. Make sure we
1679 don't pass NULL to strrchr(), working around a segfault that
1680 showed up on ZLM testing.
1682 2005-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1684 * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is
1685 the expected error code showed by the test case in bug #73053.
1687 2005-02-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1689 * io.c: another leftover.
1691 Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1693 * io.c: fixed logic in checking errno in rev 40815.
1695 Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1697 * threads.c: we don't depend on the GC checking tls
1699 * processes.c: remove unused ref to GC headers.
1701 Thu Feb 17 19:57:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1703 * io.c: remove _wapi_thread_cur_apc_pending () checks
1704 when the siscall should return immediatly and handle
1705 the case when a syscall is interrupted without
1706 erroring out, but returning a 0 read/write if possible.
1707 Still the cases of read from file need to be handled.
1709 Tue Feb 8 18:28:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1711 * threads.c: make people test with 1 MB stack per thread.
1713 2005-01-17 Dick Porter <dick@ximian.com>
1715 * timefuncs.h: Make WapiFileTime endian-aware, as it's often
1716 cast to and from 64bit ints. Fixes bug 71213.
1718 2005-01-11 Dick Porter <dick@ximian.com>
1720 * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
1723 Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>
1725 * atomic.h: Fix functions on s390.
1727 Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>
1729 * atomic.h: fix some functions on ppc (tests/interlocked.cs).
1731 2005-01-10 Dick Porter <dick@ximian.com>
1733 * misc.c (_wapi_calc_timeout): Guard against overflow when
1734 calculating timeouts. This makes waiting with a large
1735 (Int32.MaxValue) timeout not return immediately.
1737 2004-12-23 Ben Maurer <bmaurer@ximian.com>
1739 * io.c (io_ops): make this `const' so it is shareable (well, only
1740 really shareable if it is statically linked...)
1742 Mon Dec 20 11:58:33 CET 2004 Paolo Molaro <lupus@ximian.com>
1744 * threads.c, threads.h: add accessor to get the pthread_key_t for
1747 2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1749 * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS
1750 if it exists and is not the same as 'src'.
1752 2004-12-01 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1754 * atomic.h : Fix InterlockedCompareExchange for s390/s390x.
1756 2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1758 * processes.c: unquote the cmd path, allow for ' or " when quoting and
1759 pass the quoted program name to the daemon, otherwise the call to
1760 g_shell_unquote in the daemon will break things up.
1762 2004-10-14 Dick Porter <dick@ximian.com>
1764 * sockets.c (_wapi_accept): Revert the previous change. We now
1765 set the accepted socket to have the same blocking status as the
1766 listening socket in managed code. This follows MS behaviour.
1768 2004-10-14 Dick Porter <dick@ximian.com>
1770 * sockets.c (_wapi_accept): On Darwin, make sure a newly
1771 accept()ed socket is blocking. Fixes bug 67355, patch by
1772 grompf@sublimeintervention.com.
1774 2004-10-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1776 * system.c: check the number of online processors instead of the
1777 existing ones. Sanitize return value if it's an error.
1779 2004-10-03 Ben Maurer <bmaurer@ximian.com>
1781 * system.c: Add support for getting the # of cpus.
1783 2004-09-28 Dick Porter <dick@ximian.com>
1785 * io.c (pipe_close_private): Fix one small typo in the last change
1786 that totally hosed process creation with redirected pipes.
1788 2004-09-24 Dick Porter <dick@ximian.com>
1795 * handles-private.h: Cope when a file descriptor is reused while
1796 the handle that thought it owned it is still referenced, instead
1797 of asserting. Probably fixes bug 66479, though we've been unable
1800 2004-09-09 Dick Porter <dick@ximian.com>
1803 * io.c: Set error codes everywhere.
1805 2004-09-06 Dick Porter <dick@ximian.com>
1807 * handles.c (_wapi_handle_unref): Reset the private record's type
1808 (CloseHandle): Check for a fd mapping failure, and return FALSE.
1809 (_wapi_handle_process_fork): Fix long-standing bug in checking
1810 handle return values. Also do the required bookkeeping with the
1811 new process's handles.
1813 * daemon.c: When creating a new process's handles, check whether
1814 the shared space needs to be increased
1816 2004-09-05 Zoltan Varga <vargaz@freemail.hu>
1818 * shared.c (_wapi_shm_file): Fix leaking of filename.
1820 2004-08-19 Dick Porter <dick@ximian.com>
1822 * handles.c (_wapi_handle_count_signalled_handles): Fix thinko
1823 introduced with the fd offset stuff: unlock handles properly when
1824 backing off. Fixes the monologue hang at exit.
1826 2004-08-18 Dick Porter <dick@ximian.com>
1829 * io.c: Check that new fds fit in the table, return error if not
1831 * daemon.c (_wapi_daemon_main):
1832 * handles.c (shared_init): Have all processes agree on a size for
1835 2004-08-17 Dick Porter <dick@ximian.com>
1837 * daemon.c (process_new):
1838 * handles.c (_wapi_handle_new_internal): Cope when the space
1839 reserved for file descriptors is larger than the shared segment
1840 size. Fixes the crash reported when running mono under gdb on
1843 2004-08-16 Dick Porter <dick@ximian.com>
1847 * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
1848 error checking with passed-in file descriptors.
1850 2004-08-11 Dick Porter <dick@ximian.com>
1853 * io.c: Returned handle values are the file descriptor the handle
1857 * handles-private.h:
1858 * daemon.c: Reserve the range of handles that can have the same
1859 values as file descriptors. These won't be used, but the values
1860 will be used as file, console, pipe or socket handles. The fd to
1861 handle mapping is done internally and is invisible to users.
1864 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
1865 reserve a chunk of handle space.
1867 2004-08-04 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1869 * atomic.h: add support for 64-bit S/390
1871 2004-07-22 Dick Porter <dick@ximian.com>
1874 * threads.c: Move the destruction of the internal thread data to
1875 after the thread has been joined. Fixes bug 61418.
1877 2004-07-14 Dick Porter <dick@ximian.com>
1879 * wait.c (test_and_own): When not waiting for all handles to
1880 become signalled, only own and return the lowest. All the
1881 documentation suggests that the old way was correct, but
1882 experimentation shows it actually works like this. Patch by
1883 Sébastien Robitaille
1884 (sebastien.robitaille@croesus.com), fixes bug 61511.
1886 2004-07-09 Ben Maurer <bmaurer@ximian.com>
1888 * threads.c: register roots for gc
1890 2004-07-08 Dick Porter <dick@ximian.com>
1892 * io.c (file_seek): If there is a high 32bit offset part, make
1893 sure the low part isn't sign-extended. Set error codes when
1894 returning failure. Fixes bug 61131.
1896 2004-07-06 Dick Porter <dick@ximian.com>
1898 * io.c (file_setfiletime): Check for underflow when converting to
1899 time_t values. Set error codes when returning failure. Fixes bug
1902 2004-07-05 Dick Porter <dick@ximian.com>
1904 * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable.
1906 * daemon.c (unref_handle): Only destroy a handle if all processes
1907 have released it, not just the current one. Fixes bug 60887.
1909 2004-06-30 Zoltan Varga <vargaz@freemail.hu>
1911 * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
1912 to prevent warnings.
1914 2004-06-24 Dick Porter <dick@ximian.com>
1916 * mutexes.c: Indicate when a named mutex was reused
1918 2004-06-24 Dick Porter <dick@ximian.com>
1920 * threads.c (SuspendThread):
1921 * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a
1922 while loop. See bug 58161.
1924 Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro <lupus@ximian.com>
1926 * io.c: don't use sharemode for on-disk file permissions: it's used
1927 for shared access to the open file.
1929 2004-06-22 Dick Porter <dick@ximian.com>
1931 * events.c (CreateEvent): When creating an auto-reset event that
1932 is initially owned, make sure the set count starts at 1.
1934 2004-06-18 Dick Porter <dick@ximian.com>
1937 * events.c: Auto-reset events need to release one thread for each
1938 time SetEvent() is called. Fixes bug 41292.
1942 * mutexes.c: Scan for mutexes that are still locked by a thread
1943 when it exits. Fixes the MS demo app linked by bug 41292.
1945 * wait.c (test_and_own): Make sure a handle is signalled before it
1948 2004-06-16 Dick Porter <dick@ximian.com>
1950 * timed-thread.c: Call the thread cleanup exit routine before taking
1951 the join mutex, because this could deadlock if another thread tries
1952 to join in the meantime. This fixes the hang-at-exit problem seen
1955 2004-06-03 Lluis Sanchez Gual <lluis@ximian.com>
1957 * threads.c: Implemented SleepEx.
1958 * threads.h: Fixed SleepEx signature.
1960 2004-06-03 Miguel de Icaza <miguel@ximian.com>
1962 * threads.c: When running under valgrind, do not allocate too much
1963 stack, as Valgrind default is 1 meg.
1965 2004-05-27 Dick Porter <dick@ximian.com>
1968 * io.c: Implemented LockFile() and UnlockFile()
1970 2004-05-21 Dick Porter <dick@ximian.com>
1972 * io.c (CreateFile): Check for existing share modes when opening
1976 * handles-private.h:
1977 * daemon-messages.h:
1978 * daemon.c: Maintain a hash of file share modes, keying on device
1979 and inode (to cope with symlinks.)
1981 2004-05-20 Lluis Sanchez Gual <lluis@ximian.com>
1983 * daemon-messages.c: Retry if the communication with the daemon is
1984 interrupted by a signal.
1985 * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped.
1986 Only return an error in this case if there is something in the apc queue
1987 (which means that it is an interruption requested by the "user").
1988 * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as
1989 true since the wait is small.
1990 * shared.c: Retry write calls when interrumped by a signal.
1991 * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which
1992 returns TRUE if there are pending asynchronous calls (APC) for the
1993 provided thread. Also added _wapi_thread_dispatch_apc_queue which calls
1994 the enqueued APCs. Defined a new struct ApcInfo that holds information
1995 about an enqueued APC.
1996 * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same
1997 as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue.
1998 These last two methods call the corresponding apc methods in
1999 thread-private using the provided thread handle.
2000 * threads.h: Added QueueUserAPC.
2001 * uglify.h: Added WapiApcProc (needed by QueueUserAPC).
2002 * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and
2003 WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support
2004 for APCs in those two methods and also in SleepEx.
2006 2004-05-17 Dick Porter <dick@ximian.com>
2008 * io.c (CopyFile): Speed up. Fixes bug 57859.
2010 2004-05-13 Dick Porter <dick@ximian.com>
2011 * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current
2012 thread doesn't own the mutex, rather than assert()ing.
2014 2004-05-11 Dick Porter <dick@ximian.com>
2016 * shared.c (_wapi_shm_attach): Cope when a previous daemon startup
2017 attempt failed, leaving shared files that look like a daemon is
2020 2004-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2023 (SetFileAttributes): don't the the exec bit if the corresponding read
2026 2004-05-10 Zoltan Varga <vargaz@freemail.hu>
2028 * io.c (FindFirstFile): Fix invalid free.
2030 2004-05-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2032 * io.c: translate from GFileError to errno codes and don't free
2033 variables right after calling mono_io_scandir, as we may overwrite
2036 2004-05-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2038 * io.c: g_dir_open return ENOENT for directories on which we don't have
2039 read/execute permission, while returning EPERM for anything below those.
2040 So, change ENOENT by EPERM if the directory exists.
2042 2004-05-07 Dick Porter <dick@ximian.com>
2044 * io.c (SetFileAttributes): Don't have failed chmod()s cause a
2045 "file not found" error. Fixes bug 54032.
2047 2004-05-07 Dick Porter <dick@ximian.com>
2049 * io.c (FindFirstFile): Comment out a windows-compatibility check
2050 that breaks when directories have metachars in their names.
2051 Workaround for bug 58116.
2053 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2055 * io.c: fixed for FindFirstFile for empty directories. Closes
2058 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2060 * processes.c: set the start time for the current process. Fixes bug
2063 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2065 * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
2066 * io.c: implemented scandir using glib functions.
2068 2004-05-04 Dick Porter <dick@ximian.com>
2070 * daemon.c (read_message): Return FALSE on error so the GSource
2071 callback itself can return FALSE. Cures the infinite loop poll()
2073 * shared.c: Fix some daemon startup race conditions.
2075 2004-04-29 Miguel de Icaza <miguel@ximian.com>
2077 * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k,
2078 use the stack, do not use dynamic memory.
2080 2004-04-29 Zoltan Varga <vargaz@freemail.hu>
2082 * io.c: Add scandir implementation for platforms which do not have
2085 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2087 * io.[ch]: implemented GetLogicalDriveStrings.
2089 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2092 * sockets.c: use the field name from configure when accessing sigval
2093 pointer field. Makes this work on the Mac.
2095 2004-04-28 Bernie Solomon <bernard@ugsolutions.com>
2097 * atomic.c: (InterlockedExchange) fix typo for
2100 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2103 * sockets.c: added check for sys/aio.h.
2105 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2107 * error.[ch]: added _wapi_get_win32_file_error...
2108 * io.c: ... which was _wapi_get_win32_error here.
2109 * sockets.c: rename the function calls here too.
2111 2004-04-28 Dick Porter <dick@ximian.com>
2113 * daemon-messages.c: Avoid a deadlock when a thread is killed while
2114 waiting for the daemon by using a recursive mutex. Helps bug 56699.
2116 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2118 * io.c: fixed leak in async_notifier().
2120 * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl
2123 * threads.c: removed old comment.
2125 2004-04-26 David Waite <mass@akuma.org>
2127 * daemon-messages.h:
2134 * wapi-private.h: remove comma from end of enumeration declarations
2135 * status.h: cast unsigned int types to int for enum assignment
2137 2004-04-26 David Waite <mass@akuma.org>
2140 * timefuncs.c: declare 64-bit constants as long long types (i.e.
2143 2004-04-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2145 * socket-wrappers.h: _wapi_socket == WSASocket now. Added
2146 WSA_FLAG_OVERLAPPED.
2148 * sockets.c: new unused parameters for _wapi_socket.
2150 2004-04-22 Miguel de Icaza <miguel@ximian.com>
2152 * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle
2153 the fact that MacOS X is a piece of junk (sem_init is *defined* in
2154 the libc, but they return `not implemented').
2156 2004-04-22 Dick Porter <dick@ximian.com>
2159 * handles-private.h: Reference the handle when it is locked, so
2160 that another thread can't blow it away while we're waiting for it
2161 to become signalled.
2172 * handles-private.h:
2175 * daemon-messages.c:
2176 * critical-sections.c:
2177 * atomic.c: Added pthreads cleanup handlers and error asserts
2180 * handles.c: Fixed the gcc "variable might be used uninitialised"
2181 warnings. They can't happen, but gcc doesn't know that
2182 g_assert()s don't return.
2184 Fixed the declaration of _wapi_handle_process_kill() so that it
2185 expects the correct type for the pid.
2187 * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that
2188 hasn't been used in ages and just made the code more complex.
2190 2004-04-17 Zoltan Varga <vargaz@freemail.hu>
2192 * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
2193 warnings. Fixes #57168.
2195 2004-04-16 Dick Porter <dick@ximian.com>
2197 * threads.c (Sleep): Using div(3) with a negative (when signed)
2198 numerator causes the quotient to be 0 and the remainder to be the
2199 numerator. This feeds a small negative value to nanosleep(3),
2200 which will return immediately and cause a busy wait. Fixes bug
2203 2004-04-15 Dick Porter <dick@ximian.com>
2206 * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3)
2207 and fnmatch(3) instead of glob(3). glob() can't cope with being
2208 given filenames containing metachars. This fixes bug 40557.
2210 2004-04-14 Bernie Solomon <bernard@ugsolutions.com>
2212 * security.c: #warning is a GCC-ism
2214 2004-04-13 Sebastien Pouliot <sebastien@ximian.com>
2216 * security.c: Removed GetUserName as glib g_get_user_name does a
2217 better (portability) job. Added ImpersonateLoggedOnUser and
2220 2004-04-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2222 * mono-mutex.h: move pthread_mutex_timedlock declaration to...
2223 * mono-mutex.c: ...here. It was causing a warning that prevented
2224 libgdiplus compilation.
2226 2004-04-04 Miguel de Icaza <miguel@ximian.com>
2228 * security.c (GetUserName): Make it work on MacOS X
2230 2004-04-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2232 * security.c: use getpwuid_r if available. This one is thread-safe.
2234 2004-04-02 Sebastien Pouliot <sebastien@ximian.com>
2236 * Makefile.am: Added security.c|h.
2237 * security.c: New file for security related functions. Added function
2238 GetUserName to fix #56144.
2239 * security.h: New. Header file for security.c
2240 * wapi.h: Added include for security.h
2242 2004-03-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2244 * daemon-messages.h: added kill structs.
2246 * daemon.c: implemented process_process_kill.
2247 * handles-private.h: define process_process_kill.
2248 * handles.c: implemented _wapi_handle_process_kill.
2249 * processes.[ch]: implemented TerminateProcess.
2251 2004-03-25 Bernie Solomon <bernard@ugsolutions.com>
2253 * daemon.c (rem_fd): On solaris you seem to get an
2254 error even after removing the input source so don't
2255 try and rem_fd it twice.
2257 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
2259 * daemon.c: in process_post_mortem, If the child terminated due to the
2260 receipt of a signal, the exit status must be based on WTERMSIG, since
2261 WEXITSTATUS returns 0 in this case.
2263 2004-03-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2265 * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.
2267 2004-03-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2269 * daemon.c: only call getdtablesize () once.
2270 * processes.c: wait 500 ms to check if execve failed and throw the same
2271 exception as MS on failure. Fixes bug #32809.
2273 2004-03-17 Bernie Solomon <bernard@ugsolutions.com>
2275 * io.c (async_notifier): use "union sigval" rather
2276 than sigval_t as Solaris doesn't have sigval_t
2277 (which isn't in IEEE 1003.1 either).
2279 2004-03-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2281 * io.c: added debug stuff and removed a few redundant lines in
2284 2004-03-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2286 * io-private.h: added new fields for file structure. Declare
2287 _wapi_io_add_callback.
2289 * io.c: added _wapi_get_win32_error, support aio_read/write in
2290 file_read/write. Implemented _wapi_io_add_callback, which is where
2293 * io.h: added new fields for WapiOverlapped and typedef for the
2296 * processes.c: fixed off-by-one bug when handling environment variables
2299 * threads.[ch]: implemented BindIoCompletionCallback.
2301 * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE.
2303 2004-03-14 Zoltan Varga <vargaz@freemail.hu>
2305 * socket-wrappers.h: Remove extra semicolon.
2307 2004-03-03 Dave Camp <dave@ximian.com>
2309 * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
2310 Use a new main context.
2312 2004-03-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2315 (GetFileAttributes): set the error depending on errno instead of
2316 setting ERROR_FILE_NOT_FOUND always. See bug #55160.
2318 2004-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2321 (CopyFile): free the buffer on error.
2323 (WSAIoctl): free the buffer on error.
2325 2004-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2327 * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT.
2329 * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW
2330 using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style.
2332 2004-01-27 Bernie Solomon <bernard@ugsolutions.com>
2334 * shared.c (_wapi_shm_file): add hostname
2335 to shared data file names to handle NFS mounted
2338 Mon Jan 26 16:15:03 CET 2004 Paolo Molaro <lupus@ximian.com>
2340 * sockets.h: remove obsolete soklen_t typedef.
2342 Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>
2344 * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket
2345 wrappers to its own non-installed header file.
2347 2004-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2350 (FindFirstFile): unlock the handle if FindNextFile fails.
2351 (FindNextFile): g_free a couple of pointers before retrying.
2354 (WaitForMultipleObjects): if only one handle provided, use
2355 WaitForSingleObject.
2357 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2359 * handles-private.h: (_wapi_handle_type) check
2360 for segment in range before using it
2362 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2364 * thread-private.h: _wapi_thread_ops is now const
2367 Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>
2369 * threads.c, timed-thread.c, timed-thread.h: use mach
2370 semaphores on Darwin (MacOSX) since the posix ones
2371 are mostly broken there (threads are not created suspended
2372 and they can start executing before they are fully initialized
2373 like in tests/thread-static.cs).
2375 Mon Dec 22 17:18:45 CET 2003 Paolo Molaro <lupus@ximian.com>
2377 * atomic.h: ppc fixes.
2379 2003-12-19 Bernie Solomon <bernard@ugsolutions.com>
2381 * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
2384 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2386 * shared.c: (_wapi_shm_open) make scratch file
2387 not have to immediately regrow to avoid remaps
2388 (HPUX can't cope with these).
2389 (_wapi_shm_attach) use actual size of file
2390 to set scratch data_len for the creating process.
2392 * handles.c: (_wapi_handle_new_internal) make
2393 sure mutex & cond var are initialized even for
2394 non process shared ones.
2395 (_wapi_handle_unref) always call destroy
2396 routines on mutex & cond var
2398 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2400 * daemon.c: change channel data structure so
2401 input sources are removed from glib event loop
2402 properly. xsp works better on Solaris and
2405 2003-12-12 Bernie Solomon <bernard@ugsolutions.com>
2407 * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
2408 definition with file & line number for non-GCC
2411 2003-12-08 Bernie Solomon <bernard@ugsolutions.com>
2413 * Makefile.am: make sure hppa_atomic.s is in distribution
2415 2003-12-01 Dick Porter <dick@ximian.com>
2418 * mutexes.c (CreateMutex):
2419 * mutex-private.h (struct _WapiHandle_mutex):
2420 * handles.c: Look up certain handle types by name, in a shared
2421 namespace. Currently only mutex handles have this implemented.
2424 * semaphores.c (CreateSemaphore):
2425 * events.c (CreateEvent): Fix signature
2427 2003-11-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2429 * io.c: don't call g_free before testing errno as it may modify it.
2430 If the path exists, return an error if it's not a directory. Fixes
2433 2003-11-20 Dick Porter <dick@ximian.com>
2435 * io.c: Missed a little-endian UTF16 conversion. Patch from
2436 Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.
2438 2003-10-29 Dick Porter <dick@ximian.com>
2440 * io.c (MoveFile): If the move crosses filesystems, try and fall
2441 back to copy and delete. Patch from Jörg Rosenkranz
2442 (JoergR@voelcker.com), fixes bug 50298.
2444 2003-10-28 Dick Porter <dick@ximian.com>
2446 * io.c: Use the new encoding conversion to cope with non-utf8
2447 locales in filenames.
2449 * processes.c: Ditto for process arguments.
2451 Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro <lupus@ximian.com>
2453 * atomic.h: some ppc inline asm fixes (incorrect use of labels,
2454 incorrect register constraints, incorrect clobber lists).
2456 2003-10-13 Bernie Solomon <bernard@ugsolutions.com>
2458 * Makefile.am hppa_atomic.s: add HP 64bit
2459 implementation of atomic ops
2461 2003-10-13 Zoltan Varga <vargaz@freemail.hu>
2463 * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
2464 a conditional for platforms that don't have it.
2466 2003-10-09 Bernie Solomon <bernard@ugsolutions.com>
2468 * threads.c: (CreateThread) use stacksize argument
2469 if non-zero - change default for 64 bits to 4Mb
2471 2003-09-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2473 * sockets.c: set last error when socket creation fails. This shed some
2474 light on bug #49015.
2476 2003-09-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2478 * processes.c: fixed bug #48973: we only change \ by / for the argument
2479 to be used as command.
2480 When getting the program name from the args, don't let the space between
2483 2003-09-24 Bernie Solomon <bernard@ugsolutions.com>
2485 * atomic.h atomic.c: fix sparc so lock is
2486 global, increment does so and it compiles under Sun compiler.
2488 2003-09-22 Bernie Solomon <bernard@ugsolutions.com>
2490 * handles.c: include <string.h> directly as may
2491 not be nested in <sys/un.h> like Linux
2493 2003-09-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2496 (DeleteFile): call SetLastError on failure. Fix by
2497 richard.torkar@htu.se (Richard Torkar). Closes bug #48222.
2499 2003-09-15 Lluis Sanchez Gual <lluis@ximian.com>
2501 * daemon.c: In compare_process(), discard handles already signalled.
2503 2003-09-02 Dick Porter <dick@ximian.com>
2505 * io.c: Work around glib brain-dead assumptions about utf8-encoded
2506 filenames. Fixes bug 30781.
2508 2003-08-28 Dick Porter <dick@ximian.com>
2510 * critical-sections.c: Patch from Bernie Solomon
2511 <bernard@ugsolutions.com> to emit a warning if locking a critical
2514 2003-07-23 Dick Porter <dick@ximian.com>
2517 * daemon.c (maybe_exit): Avoid the race condition when the daemon is
2518 closing but another client comes along when the shared data is still
2519 visible. Should fix bugs 33671 and 35213.
2521 2003-07-23 Dick Porter <dick@ximian.com>
2523 * handles.c: Initialise handle mutex and cond. Fix by
2524 Bernie Solomon <bernard@ugsolutions.com>
2526 2003-07-15 Dick Porter <dick@ximian.com>
2528 * timed-thread.c (timed_thread_start_routine): Fix virtual memory
2529 leak when threads quit. Fixes bug 44067.
2531 Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro <lupus@ximian.com>
2533 * io.c: never add write permission for group or others in
2534 SetFileAttributes ().
2536 2003-06-17 Dick Porter <dick@ximian.com>
2538 * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
2539 ignore the unsupported ones ("fixes" bug 44977).
2541 2003-06-17 Lluis Sanchez Gual <lluis@ximian.com>
2543 * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for
2544 high ms values (there was an overflow).
2546 2003-06-17 Zoltan Varga <vargaz@freemail.hu>
2548 * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.
2550 2003-06-11 Dick Porter <dick@ximian.com>
2552 * shared.c: Fix shared directory creation. Patch from
2553 Pablo Baena <pbaena@uol.com.ar>
2555 2003-06-10 Dick Porter <dick@ximian.com>
2557 * atomic.c: Delete the useless compile warning
2559 2003-06-09 Dick Porter <dick@ximian.com>
2561 * daemon.c: Lookup env as a string array. Fixes bug 44289. Also
2562 make setting the process handle value in the environment actually
2565 * processes.c: Pretty up the process name, if it happens to be
2566 "mono" such as when another mono process forks "mono foo.exe"
2568 2003-06-05 Dick Porter <dick@ximian.com>
2570 * processes.c (process_set_current): Don't do an expensive handle
2571 search at application startup, check the environment to see if the
2572 process handle has already been created.
2574 * io.c: Don't do an expensive handle search when creating stdin,
2575 stdout and stderr handles, just create them all the first time one
2582 * handles-private.h:
2583 * daemon-messages.h:
2585 * daemon.c: Support for "unlimited" number of handles and scratch
2588 Speed up application startup by passing process handle in the
2589 environment, rather than let the app scan all handles (which gets
2590 really slow when there are more than a few thousand to check.)
2592 Initialise some structs passed to syscalls, noticed by valgrind.
2595 2003-05-20 Dick Porter <dick@ximian.com>
2597 * io.c (FindFirstFile): Include . files in the glob. Fixes bug
2600 2003-05-19 Dick Porter <dick@ximian.com>
2602 * threads.c: Set the new thread's stack size to 2M. Fix needed
2603 for BSD, reported by Martin Dvorak <md@9ll.cz>
2605 2003-05-16 Dick Porter <dick@ximian.com>
2608 * io.c: Implement GetTempPath()
2610 2003-05-16 Dick Porter <dick@ximian.com>
2612 * processes.c (CreateProcess): Set some error codes
2614 2003-05-12 Dick Porter <dick@ximian.com>
2616 * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
2617 Patch from Martin Dvorak <mdvorak@ninell.cz>.
2619 2003-05-10 Dick Porter <dick@ximian.com>
2621 * io.c (CopyFile): Copy file mode as well as file data. Based on
2622 suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
2625 2003-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2627 * handles.c: don't call GC_gcollect when creating new handles.
2629 2003-05-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2631 * handles.c: added some debugging code. Call GC_gcollect
2632 before creating a new handle. It makes Lupus' test run smoother and
2633 faster (from 62 to 83 request per second). Notice that calling
2634 GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does
2635 not improve nor degrade the performance, so i don't do it.
2637 2003-05-02 Dick Porter <dick@ximian.com>
2639 * sockets.c: Rearrange closesocket() and socket_close_private(),
2640 and remember to unref the handle, so we don't leak socket handles.
2641 Fix from Pelle Johnsen <pelle.johnsen@mail.dk>
2643 2003-04-11 Dick Porter <dick@ximian.com>
2645 * atomic.h: ARM atomic operations by Malte Hildingson
2646 <tds00mahi@tellus.thn.htu.se>
2648 Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>
2650 * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.
2652 2003-04-03 Martin Baulig <martin@ximian.com>
2654 The following change is conditional to `WITH_INCLUDED_LIBGC'
2655 which is not yet enabled by default.
2657 * threads.c (SuspendThread, ResumeThread): Fully implemented this.
2658 (gc_init): New static function; install a signal handler for
2659 SIGPWR which is used to suspend threads. [FIXME: it SIGPWR
2660 doesn't exist on all Unix systems, we need to find another
2662 (mono_wapi_push_thread_stack): New public function. Tells the
2663 garbage collector about the current stack pointer of a suspended
2666 2003-04-03 Martin Baulig <martin@ximian.com>
2668 * timed-thread.h (TimedThread): Added `suspended_sem',
2669 `suspend_count' and `stack_ptr'.
2671 2003-03-28 Dick Porter <dick@ximian.com>
2673 * atomic.h: PPC support gratiously donated to the public domain
2674 by John Duncan <jddst19@mac.com>
2676 2003-03-20 Dick Porter <dick@ximian.com>
2678 * sockets.c (_wapi_connect): If connect() fails with EACCES, try
2679 setting SO_BROADCAST and connecting again. Fixes bug 39178.
2681 2003-03-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2683 * processes.c: included Jerome Laban's patch and call SetLastError when
2684 the executable is not found.
2686 2003-03-03 Dick Porter <dick@ximian.com>
2688 * io.c (CreateFile): Try opening directories readonly, so that
2689 timestamps can be adjusted. Patch by Elan Feingold
2690 <efeingold@mn.rr.com>.
2692 2003-02-25 Dick Porter <dick@ximian.com>
2694 * shared.c (_wapi_shm_attach): Return a failure code on system
2695 call errors, rather than exiting.
2697 2003-02-21 Dick Porter <dick@ximian.com>
2699 * processes.c (GetCurrentProcessId): Use the current process
2700 handle to return the process ID, as getpid() is unreliable
2701 (linuxthreads gives each thread a different pid). Fixes bug
2704 2003-02-21 Dick Porter <dick@ximian.com>
2706 * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug
2709 2003-02-11 Dick Porter <dick@ximian.com>
2712 * timefuncs.c: Added GetTickCount()
2714 2003-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2716 * error.c: added WSA_EHOSTUNREACH mapping.
2718 2003-01-26 Miguel de Icaza <miguel@ximian.com>
2720 * io.c (SetFileAttributes): This routine is not currently
2721 implemented for the general case, but I added a special case to
2722 set the executable bit on Linux.
2724 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
2726 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
2728 2003-01-08 Dick Porter <dick@ximian.com>
2730 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
2732 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
2734 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2735 Check for an implementation which says it supports
2736 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
2737 defines the symbol. Defined but with a value of -1 still
2738 means that it is unsupported.
2740 2002-12-08 Martin Baulig <martin@ximian.com>
2742 * handles.c (_wapi_handle_new): Create new non-shared handles with
2743 an initial refcount of 1, not 0.
2745 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
2747 * threads.c (TlsGetValue): removed unnecessary mutex
2749 2002-11-20 Dick Porter <dick@ximian.com>
2751 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
2752 need to store their data structure too.
2754 * threads.c: Make sure the threading data is initialised wherever
2757 2002-11-15 Dick Porter <dick@ximian.com>
2759 * timed-thread.c: Removed unneeded parameters in
2760 _wapi_timed_thread_attach().
2762 * threads.c: Renamed AttachThread() to make it not look like
2763 external API. Removed unneeded parameters.
2765 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2767 * error.[ch]: added errno_to_WSA (). It displays a warning and return
2768 WSASYSCALLFAILURE if there is no error mapping for the given errno,
2770 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
2772 2002-10-31 Dick Porter <dick@ximian.com>
2775 * io.c: Define and use INVALID_FILE_ATTRIBUTES
2777 2002-10-07 Dick Porter <dick@ximian.com>
2780 * daemon.c: Use a more accurate time source for process start and
2783 2002-10-03 Dick Porter <dick@ximian.com>
2787 * threads.c: Fixes for freebsd. Make sure that mutex and condition
2788 creation and deletion happen in the process that owns them, when
2789 POSIX shared thread objects aren't supported. This breaks on
2790 freebsd, as pthread_t is a pointer to data.
2792 2002-10-02 Dick Porter <dick@ximian.com>
2794 * shared.c: Use mmap() instead of sysv shm for the shared data.
2796 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
2800 * daemon.c: mmap()ed regions survive fork, so just pass the
2801 pointer to _wapi_daemon_main instead of mapping it again.
2803 2002-10-01 Dick Porter <dick@ximian.com>
2805 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
2806 Unfortunately libgc uses the same thread suspend technique that I
2807 want to, and the two don't mix: libgc will deadlock when it tries
2808 to stop the world if a thread has already been suspended by
2809 someone else. Just do the simple suspended create rather than the
2810 general purpose thread suspension for now.
2812 * threads.c: Pass create flags to the timed_thread create call, to
2813 implement suspended thread creation. ResumeThread() partially
2814 implemented, to cope with the case where a newly created but
2815 suspended thread is launched.
2817 2002-09-30 Dick Porter <dick@ximian.com>
2819 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
2822 2002-09-27 Dick Porter <dick@ximian.com>
2824 * semaphores.c: Only include semaphore.h if it's present. Patch
2825 for BSD from jmmv@hispabsd.org (Julio Merino).
2827 2002-09-27 Dick Porter <dick@ximian.com>
2829 * processes.c: Pass environment and working directory to the
2830 daemon when forking. Don't let argv[0] be duplicated when looking
2831 for the program name. Implement EnumProcessModules (simple
2832 version for now, lsof-style later if needed), GetModuleBaseName,
2833 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
2834 aren't available on Linux).
2836 * process-private.h: Store the process name, and the working set
2840 * handles-private.h: New functions to store and retrieve an array
2841 of strings in the scratch space
2843 * daemon.c: Don't miss deleting some handles when a client exits
2844 (we used to rely on the client doing the final cleanup, but
2845 obviously if the client is no longer there the daemon has to do
2848 Process forking now sets the environment and the working
2851 * io.c: Don't confuse fd 0 with an unassigned handle struct
2853 * atomic.h: Add a google cache alternative to the msdn URL
2855 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2858 (_wapi_recvfrom): added ECONNRESET to the switch.
2860 2002-09-24 Mark Crichton <crichton@gimp.org>
2862 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
2865 2002-09-19 Mark Crichton <crichton@gimp.org>
2867 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
2868 dont have Linux's abstract filesystem for sockets.
2870 2002-09-19 Mark Crichton <crichton@gimp.org>
2872 * atomic.h: Added SPARC atomic asm code.
2873 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2874 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
2875 Solaris 9, however, the code paths don't seem to work. More testing
2876 on the shared case is *really* needed.
2878 2002-09-03 Dick Porter <dick@ximian.com>
2881 * threads.c: Removed PosixKillThread(), because it's not in the
2884 2002-08-20 Dick Porter <dick@ximian.com>
2886 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
2887 multiples of 4 bytes, to keep header structures aligned. Needed
2888 for sparc, at least. (Patch from crichton@gimp.org)
2890 * handles.c: Removed 'disable_shm' variable (we've defaulted to
2891 building with shm enabled for months now)
2893 2002-08-19 Dick Porter <dick@ximian.com>
2895 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
2896 for legacy NeXT-based systems.
2898 2002-08-12 Dick Porter <dick@ximian.com>
2900 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
2901 from Joseph Wenninger <kde@jowenn.at>)
2903 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
2905 * threads.c: use fast spinlocks by default
2907 2002-08-02 Dick Porter <dick@ximian.com>
2909 * io.c (GetStdHandle): Add a handle reference when returning a
2910 duplicate console handle. This fixes the unref_handle errors in
2913 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
2915 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
2918 2002-08-01 Dick Porter <dick@ximian.com>
2920 * threads.c: Use atomic spinlocks in TLS functions
2923 * Makefile.am: Added mono-spinlock.h
2925 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
2927 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
2928 these are needed for sendmsg() and also for struct msghdr (at
2929 least on Solaris). Solaris still won't build because struct msghdr
2930 doesn't have msg_flags, msg_control, or msg_controllen members.
2931 (CMSG_SPACE): Define for systems that don't have it.
2934 2002-07-20 Dick Porter <dick@ximian.com>
2940 * handles.c: Implemented pipe handles
2943 * daemon.c: Fixed bug in handle closing.
2946 * daemon.c: Forked processes now close all open file descriptors.
2948 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
2950 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
2953 2002-07-19 Martin Baulig <martin@gnome.org>
2955 * threads.c (ExitThread): Call exit() if no threads has been
2958 2002-07-17 Dick Porter <dick@ximian.com>
2960 * daemon-messages.c: Freebsd fixes from Andreas Kohn
2961 <andreas.kohn@gmx.net>
2963 2002-07-15 Dick Porter <dick@ximian.com>
2965 * io.c: Removed bogus console_flush() method, that was just cut
2966 and pasted from file_flush when I separated the two handle types.
2968 2002-07-12 Dick Porter <dick@ximian.com>
2970 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
2971 flags. Fixes bug 27633.
2973 2002-07-12 Dick Porter <dick@ximian.com>
2977 * daemon.c: Use size of sockaddr_un.sun_path from config.h
2979 2002-07-12 Dick Porter <dick@ximian.com>
2981 * processes.c (CreateProcess): Send stdin, stdout and stderr
2982 handles if the startup info doesnt specify new ones
2984 * io.c (GetStdHandle): Return the same handle when the same
2985 standard handle is requested
2987 * handles.c: Pass file descriptors when forking
2989 * daemon.c: Use supplied file descriptors when forking a new
2992 * daemon-messages.h:
2993 * daemon-messages.c: Pass stdin, stdout and stderr file
2994 descriptors to the daemon (used when forking)
2996 2002-07-11 Miguel de Icaza <miguel@ximian.com>
2998 * daemon.c (_wapi_daemon_main): Use sizeof
2999 (main_socket_address.sun_path) instead of hardcoded 108 value.
3001 * handles.c (shared_init): Use sizeof
3002 (shared_socket_address.sun_path) instead of hardcoded 108 value.
3004 2002-07-10 Dennis Haney <davh@davh.dk>
3008 * daemon.c: Lots of documentation, some added error checking, and
3009 code readability improvements.
3011 * daemon-messages.h: Add the Error request type to improve error
3014 * daemon-messages.c: Do a bit more error checking on send() and
3015 recv(), and log errors with a higher severity level.
3017 2002-07-04 Dick Porter <dick@ximian.com>
3019 * daemon.c (process_process_fork): Fix argument handling, due to
3020 buggy understanding of g_strsplit() behaviour.
3022 2002-07-03 Dick Porter <dick@ximian.com>
3025 * threads.c: Implement OpenThread(). Define access-control values
3031 * Makefile.am: Added access.h, to hold shared access-control
3034 2002-07-02 Dick Porter <dick@ximian.com>
3036 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
3038 2002-07-02 Dick Porter <dick@ximian.com>
3040 * handles.c (shared_init): Make a second attempt to contact the
3041 daemon if the shared memory attach succeeds, but the connect()
3042 fails. (This copes with the daemon crashing without cleaning up
3048 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
3049 the daemon, it's now built into the library.
3051 2002-06-25 Dick Porter <dick@ximian.com>
3054 * handles-private.h:
3055 * daemon-messages.h:
3056 * daemon.c: Process forking and handle data management
3059 * process-private.h:
3060 * processes.c: Process forking and other support functions
3062 2002-06-25 Dick Porter <dick@ximian.com>
3064 * versioninfo.h: PE resource decoding
3066 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
3067 to be told the string length
3069 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
3070 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
3073 2002-06-12 Dick Porter <dick@ximian.com>
3076 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
3077 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
3078 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
3080 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
3082 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
3083 when writing to a closed socket.
3085 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
3087 * mono-mutex.c (mono_once): New convenience function for my
3092 * critical-sections.c:
3100 * atomic.c: Use mono_once() rather than pthread_once().
3102 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
3104 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
3105 if multiple threads all try to call _wapi_handle_new() before the
3106 shared data has been initialized, it is possible that we could get
3107 into a condition where shared_init() is being executed and later
3108 threads will pass by pthread_once() due to the fact that it has
3109 already been called and so therefor will attempt to use the shared
3110 data before it has been completely initialized. If we instead use
3111 a standard mutex locking mechanism around shared_init(), we can
3112 avoid the situation entirely. By wrapping the mutex locking in a
3113 check to see if we've already initialized the data, we can even
3114 avoid wasting resources by having to lock/unlock the mutex in any
3115 later calls (the only time we'd have to worry about
3116 locking/unlocking is the initial race to call shared_init() at
3119 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
3121 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
3123 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
3125 * daemon.c, handles.c: rename "sun" local var since it's apparently
3126 a #define on Solaris.
3128 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
3130 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
3133 2002-05-15 Dick Porter <dick@ximian.com>
3135 * wait.c: Fix a deadlock in WaitForMultipleObjects
3137 2002-05-14 Dick Porter <dick@ximian.com>
3139 * io.c: Fix a cut&paste error, found by
3140 Jaroslaw Kowalski <jarek@atm.com.pl>
3142 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
3146 2002-05-09 Dick Porter <dick@ximian.com>
3152 * handles-private.h:
3154 * Makefile.am: Remove now-unused file wait-private.h

3158 * shared.c: Better error messages, and report when daemon
3159 connection fails rather than blocking forever. Do some more
3160 shared memory sanity checking.
3162 * handles.c: Better error messages when connecting to shared
3163 memory and the handle daemon. Fall back to non-shared handles if
3164 an error occurs. Set the default back to 'shared handles'. Fix a
3165 crashing bug in scratch space allocation that mangled the block
3168 2002-05-07 Miguel de Icaza <miguel@ximian.com>
3170 * handles.c (shared_init): Disable SHM for now, people have too
3171 many problems with this, and the diagnostics are not helping.
3173 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
3175 * io.c: CreateFile sets win32 last error.
3177 2002-05-05 Dick Porter <dick@ximian.com>
3180 * handles-private.h:
3186 * process-private.h:
3188 * semaphore-private.h:
3192 * event-private.h: Simplify the WapiHandleOps struct: take out all
3193 the file-specific entries, leaving just the items that operate on
3194 handles themselves. Split the close operation into shared and
3195 private parts: shared close is called by the daemon.
3197 * handles.c: As above, but also pass handle allocation, ref and
3198 unref operations to the daemon. Populate the handle_ops array at
3199 compile time, because the daemon needs to call ops on handles too.
3200 Don't bother to track open handle counts any more, the daemon does
3204 * thread-private.h: As above, but also make the thread data
3207 * shared.c: Fork a handle daemon if the calling process created
3208 the shared memory segment.
3211 * daemon-messages.c:
3212 * daemon-messages.h:
3213 * Makefile.am: Build a daemon to manage handle allocation and
3214 destruction without needing to lock the shared memory
3216 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
3218 * atomic.c: Changed to use a normal mutex rather than a spinlock
3219 since a lot of platforms seem to not have them :\
3221 2002-04-30 Dick Porter <dick@ximian.com>
3223 * Completely rewrote the handle waiting code: removed the helper
3224 thread and its attendant complexity. All handle waiting is now
3225 abstracted into the WaitForSingleObject() and
3226 WaitForMultipleObjects() functions.
3228 * Implemented inter-process sharing of handles using sysv shared
3229 memory. This makes handles even more opaque, with a handle now
3230 just an index into an array.
3232 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
3234 * io.c: unitialized pointer in GetCurrentDirectory.
3236 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
3238 * threads.c: destroy the mutex at thread destruction
3239 (if/when thread destruction code will be actually called).
3240 When protecting a tls data pointer from the gc, use also the
3241 thread id in the key.
3243 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
3245 * timed-thread.c: avoid race condition when setting the thread to
3248 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3250 * jit.h: to more #include lines to avoid breaking compilation
3251 under windows when upgrading mingw and w32api to version
3254 2002-04-16 Dick Porter <dick@ximian.com>
3256 * atomic.h: Explanatory comment about lack of 80386 support
3258 2002-04-15 Dick Porter <dick@ximian.com>
3260 * atomic.h: use xaddl for InterlockedIncrement() and
3261 InterlockedDecrement(). Use cmpxchgl in a loop for
3262 InterlockedExchange() and InterlockedExchangePointer().
3264 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
3266 * unicode.c: fix unicode_len() to not access uninitialized memory
3267 (and updated to conform to mono code style).
3269 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
3271 * io.c: EEXISTS is ignored for directory creation.
3272 * mono-mutex.h: remove silly "pragma }" that emacs users insert
3273 because they use a broken editor:-)
3275 2002-03-28 Dick Porter <dick@ximian.com>
3281 * handles.c: Warning cleanups
3283 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>

3287 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
3288 some fixes to FindFirstFile() and friends.

3314 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
3316 * threads.c: use a gc-safe hash table to store tls pointers.
3318 2002-03-22 Dick Porter <dick@ximian.com>
3320 * threads.c: Fix a race condition where a thread can start and
3321 exit before the handle has been properly initialised (no reason
3322 why the handle couldn't be initialised beforehand, so do so)
3324 Fix a ms to ns conversion magnitude thinko.
3326 2002-03-21 Dick Porter <dick@ximian.com>
3328 * semaphores.c: Fix a problem when waiting for one or more
3329 semaphores, and another semaphore is Released (all waiting
3330 semaphores assumed they were signalled)
