3 * processes.c (GetExitCodeProcess): Check if a process has exited
4 and recorded it's exit code, before seeing if the process is
5 signalled. Fixes bug 325463.
7 2008-03-27 Dick Porter <dick@ximian.com>
9 * processes.c (match_procname_to_modulename): Check the whole
10 process name first, in case it is recorded as an absolute path.
13 2008-03-27 Dick Porter <dick@ximian.com>
15 * processes.c (ShellExecuteEx): Grotty kludge to work around
16 unpleasant feature in g_shell_parse_argv() where it treats '#'
17 embedded in a filename as a comment marker, and throws away the
18 rest of the line. When we're directly opening URLs quote the
19 filename, to avoid this. Fixes bug 371567.
21 2008-03-25 Dick Porter <dick@ximian.com>
23 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment file layout
26 * threads.c: Make thread handles private to the process that owns
29 2008-03-22 Kornél Pál <kornelpal@gmail.com>
31 * io-layer.h: Windows: Rename GetProcessId to __GetProcessId for targets not
32 supporting it. This fixes MSVC build with new Windows SDKs that declare
33 GetProcessId unconditionally.
35 2008-03-20 Kornél Pál <kornelpal@gmail.com>
37 * io-layer.h: Removed Windows version macros.
39 Thu Mar 13 16:24:53 CET 2008 Paolo Molaro <lupus@ximian.com>
41 * processes.c: properly check for executable files (fixes bug #368829).
43 2008-02-05 Dick Porter <dick@ximian.com>
45 * versioninfo.c (VerLanguageName): Implement VerLanguageName.
47 2008-01-31 Bill Holmes <billholmes54@gmail.com>
48 * processes.c (match_procname_to_modulename) : Added to check if the last
49 part of module name is equal to the process name.
51 * processes.c (EnumProcessModules) : Changed the first entry in the returned
52 modules array (the process module) to be populated from the entry found
55 * processes.c (get_module_name & GetModuleInformation) : In the case where
56 the module passed in is NULL, search the /proc/<PID>/maps for a name that
57 matches the process name to populate the return information.
61 2008-01-29 Zoltan Varga <vargaz@gmail.com>
63 * security.c (RevertToSelf): Make this return TRUE if impersonating is not
66 * sockets.c (_wapi_connect): Add a workaround to a solaris x86 problem where
67 getsockopt (SO_ERROR) doesn't return an error code after connect () fails. Fixes
70 2008-01-23 Dick Porter <dick@ximian.com>
72 * versioninfo.c (get_string_block): When stepping over the
73 StringTable block, do not read an extra block at the end. Fixes
74 the new part of bug 354856.
76 2008-01-19 Dick Porter <dick@ximian.com>
78 * versioninfo.c (get_stringtable_block): Cope when the StringTable
79 block is first in the resources data, and we just need to step
80 over it. Fixes bug 354856.
82 2008-01-16 Dick Porter <dick@ximian.com>
84 * threads.c (_wapi_thread_set_termination_details): Move the
85 thread abandonment to outside the shared handle lock. Fixes bug
88 2008-01-16 Dick Porter <dick@ximian.com>
90 * versioninfo.c (VerQueryValue): Include trailing null in returned
91 string length, for MS compatibility.
93 2008-01-09 Dick Porter <dick@ximian.com>
95 * versioninfo.c (get_ptr_from_rva, scan_resource_dir): Make it
96 work on big-endian systems.
97 (scan_resource_dir): Copy the resource directory entry and
98 byteswap if necessary so it works big-endian. This fixes bug
99 345972 for real this time.
100 (VerQueryValue): String values set the length to the number of
101 unicode chars, but the data length reported was already correct so
102 don't halve it again. Fixes the previous fix for bug 345972.
103 (GetFileVersionInfo): On big-endian systems, scan the resource
104 data and turn all unicode strings into UTF-16BE. FileVersionInfo
105 now works big-endian.
107 2008-01-04 Dick Porter <dick@ximian.com>
109 * versioninfo.c (VerQueryValue): Returned buffer length counts
110 chars not bytes for string data. Fixes bug 345972 again.
111 (get_enclosing_section_header): Make sure values read are treated
112 as LE. Fixes crash on ppc reported in bug 345972.
114 2007-12-17 Mark Probst <mark.probst@gmail.com>
116 * threads.c: Guard against a race condition involving
117 thread_hash_key that can occur during shutdown.
119 2007-12-08 Zoltan Varga <vargaz@gmail.com>
121 * processes.c: Include sys/mkdev.h if exists. Fixes solaris x86 build.
123 2007-12-06 Dick Porter <dick@ximian.com>
125 * versioninfo.c: Resource language values must be compared in a
126 'case'-insensitive manner. Fixes bug 345972.
128 2007-12-05 Dick Porter <dick@ximian.com>
130 * io.c (CreateFile): Create files with mode 0666 (&~umask) by
131 default. Fixes bugs 325299 and 337040.
133 2007-11-22 Dick Porter <dick@ximian.com>
135 * critical-sections.h (EnterCriticalSection): Reinstate the
136 asserts in the devel branch, so any problems aren't obscured.
138 2007-11-22 Dick Porter <dick@ximian.com>
140 * versioninfo.c (find_pe_file_resources): Make it work on 64bit
141 systems. Fixes bug 343353.
143 2007-11-21 Dick Porter <dick@ximian.com>
145 * processes.c (load_modules): Rewrite based on the libgc
146 /proc/<pid>/maps parsing to avoid using glib functions only
147 available since 2004.
148 (load_modules): Check for duplicates before adding a module to the
151 2007-11-15 Dick Porter <dick@ximian.com>
153 * processes.c (load_modules): Don't bother if we don't have
154 g_strsplit_set() and g_strv_length(). Allows building against old
156 (EnumProcessModules): Don't miss the first module returned by
159 2007-11-15 Dick Porter <dick@ximian.com>
161 * processes.c: Implement process module support by reading from
162 /proc if it's available.
165 * versioninfo.c: New functions to implement PE file version info
168 2007-11-08 Dick Porter <dick@ximian.com>
170 * critical-sections.h (EnterCriticalSection): Disable the critical
171 section asserts for the release branch
173 2007-11-05 Kornél Pál <kornelpal@gmail.com>
175 * io-layer.h: Added includes for run-time GetProcessId API detection for
178 2007-10-26 Dick Porter <dick@ximian.com>
180 * shared.c (_wapi_shm_file_open): Set the umask when opening
181 shared files, so restrictive defaults don't prevent subsequent
182 processes re-opening them.
184 2007-10-18 Zoltan Varga <vargaz@gmail.com>
186 * atomic.h (InterlockedCompareExchange): Fix the ia64 version so it works for
187 negative values too. Hopefully fixes #332700.
189 2007-09-26 Dick Porter <dick@ximian.com>
191 * io-portability.c (_wapi_io_scandir): Only update the error
192 status of glob() when performing a secondary glob() if the first
193 returned an error. Fixes bug 325107.
195 2007-09-12 Marek Habersack <mhabersack@novell.com>
197 * io-portability.c: options_init moved to
198 utils/mono-io-portability.c
199 Do not initialize portability helpers here, it's done in
201 find_file and find_in_dir moved to utils/mono-io-portability.c
203 2007-09-09 Robert Jordan <robertj@gmx.net>
205 * sockets.c (_wapi_setsockopt): Add support for FreeBSD multicast
206 sockets. Fixes #81891.
207 Code is contributed under MIT/X11 license.
209 2007-09-03 Atsushi Enomoto <atsushi@ximian.com>
211 * processes.h, processes.c : ok, they are simple string.
213 2007-09-03 Atsushi Enomoto <atsushi@ximian.com>
215 * processes.h : sigh, I really hate fixing them on windows :(
217 2007-09-03 Atsushi Enomoto <atsushi@ximian.com>
219 * processes.c : fix build again.
221 2007-09-03 Atsushi Enomoto <atsushi@ximian.com>

225 2007-09-03 Atsushi Enomoto <atsushi@ximian.com>
227 * processes.c, processes.h: added CreateProcessWithLogonW(). For now
228 it just calls CreateProcess().
229 * io-layer.h : CreateProcessWithLogonW() requires WINVER 0x0500
232 2007-08-23 Robert Jordan <robertj@gmx.net>
234 * processes.[c|h]: Implement Get|SetPriorityClass ().
235 Code is contributed under MIT/X11 license.
237 Tue Aug 21 20:08:09 CEST 2007 Paolo Molaro <lupus@ximian.com>
239 * io.c: made convert_arg_to_utf8() and write_file() static.
240 Worked around gcc's incorrect warning.
242 2007-08-20 William Holmes <billholmes54@gmail.com>
244 *io.c: Added implementation for ReplaceFile.
245 *io.h: Added deceleration for ReplaceFile method.

254 Mon Aug 20 12:36:42 CEST 2007 Paolo Molaro <lupus@ximian.com>
256 * processes.c: implemented query for user/system times using
259 2007-08-10 Dick Porter <dick@ximian.com>
261 * sockets.c (_wapi_getsockopt, _wapi_setsockopt): Check the option
262 level as well as the name when mangling some of the values. Fixes
265 2007-08-02 Dick Porter <dick@ximian.com>
267 * sockets.c: Changes in error handling, and move the SO_REUSEADDR
268 setting from metadata/socket-io.c.
270 2007-08-01 Dick Porter <dick@ximian.com>
272 * io-portability.c (_wapi_io_scandir): Special-case patterns
273 ending in '.*' so that files with no extension are also matched.
277 * wapi_glob.c: Reinstate WAPI_GLOB_APPEND, and add
278 WAPI_GLOB_UNIQUE to avoid matching the same entry twice when
281 2007-07-26 Dick Porter <dick@ximian.com>
286 * critical-sections.c:
288 * critical-section-private.h:
291 * error.c: Clean up TLS and pthreads structures. Finishes off bug

295 the io-layer has been cleaned up.
297 * mono-mutex.h (mono_mutexattr_destroy): Add this define too

304 2007-07-19 Juraj Skripsky <js@hotfeet.ch>
306 * io.c (MoveFile): Fix a leak.
308 Fri Jul 13 12:46:15 CEST 2007 Paolo Molaro <lupus@ximian.com>
310 * handles-private.h, handles.c, thread-private.h, threads.c,
311 uglify.h, wait.c: temporarily revert the alertable wait changes
312 (r79386) until the deadlock issues are fixed.
314 2007-06-22 Dick Porter <dick@ximian.com>
316 * shared.c: The non-shared mutexes weren't being initialised properly
317 on macos. Fixes bug 81929.

321 * atomic.h: Enable for all hppa targets.
322 * Makefile.am: rename hppa_atomic.s to hppa_atomic.S so the preprocessor
324 * hppa_atomic.s: Renamed to ...
325 * hppa_atomic.S: ... and updated to work on both HPUX and Linux.
327 2007-06-13 Dick Porter <dick@ximian.com>
329 * handles.c (timedwait_signal_wait_cond): Alertable waits on
330 private handles are now interrupted by signalling the same
331 condition that would end the wait if the handle became signalled,
332 rather than polling. (Shared handles still have to poll.)
334 * threads.c (_wapi_thread_queue_apc): Interrupt the thread if it's
337 * handles-private.h (_wapi_handle_current_thread_set_waiting_on):
338 Helper functions to inform the APC queuing functions when threads
339 are waiting for handles, and to interrupt the wait.
341 * wait.c (WaitForMultipleObjectsEx): Need to tell the handle
342 waiting functions if any of the handles in question are shared
344 2007-06-06 Miguel de Icaza <miguel@novell.com>

353 2007-05-21 Dick Porter <dick@ximian.com>
355 * io-portability.c (_wapi_g_dir_open): Don't propagate any errors
356 from the second call to g_dir_open, preserve the original error if
357 the second call still fails but clear the error if it succeeds.
359 2007-05-10 Dick Porter <dick@ximian.com>
361 * sockets.c (_wapi_recvfrom): Refine the fix to bug 75705 so EINTR
362 isn't returned if the remote end shuts down cleanly. Fixes zmd
363 and the second example in bug 75705.
365 2007-04-26 Dick Porter <dick@ximian.com>
367 * shared.c (_wapi_shm_semaphores_init): Need to check
368 MONO_DISABLE_SHM in this entry point, as it's called before
369 _wapi_shm_attach(). Fixes bug 81436.
371 2007-04-24 Dick Porter <dick@ximian.com>
373 * sockets.c (_wapi_recvfrom, socket_close): Force recvfrom() to
374 error if the socket is closed while the receive is blocking.
377 2007-04-13 Dick Porter <dick@ximian.com>
380 * shared.c: Complete the reimplementation of disabling of shared
381 memory, by not allocating sysv semaphores when shm disabling has
382 been requested (either at compile time or run time.)
384 * processes.c (CreateProcess): Don't synchronize locking across
385 processes when forking, when shared memory has been disabled.
387 2007-04-06 Andreas Faerber <andreas.faerber@web.de>
390 * wapi_glob.c: remove reference to sys/cdefs.h, use glib instead.
393 2007-04-05 Dick Porter <dick@ximian.com>
396 * io-portability.c (_wapi_io_scandir): Moved from io.c, and
397 changed to use a cut-down version of glob(3) that has been
398 extended to match with case-insensitivity if needed.
401 * wapi_glob.c: Cut down implementation of glob(3), based on
404 2007-03-22 Dick Porter <dick@ximian.com>
406 * sockets.c (_wapi_connect): Do additional checks when connect(2)
407 fails, because some systems don't let it be restarted. Patch
408 based on one submitted by Robert S Wojciechowski <robertw@ssgx.com>,
411 2007-03-09 Jonathan Chambers <joncham@gmail.com>
413 * io-layer.h: Remove UNICODE and _UNICODE defines as
414 these are done by configure.in now.

425 and s390x ( bnc #237611 and bxc #80892 )
427 2007-03-05 Miguel de Icaza <miguel@novell.com>
429 * io.c (CreateFile): Use FILE_ATTRIBUTE_TEMPORARY to mean 0600
430 permissions. For 80688
432 (MoveFile): Use errno_copy here, just to avoid a potential
433 errno-changing code in the future from g_free.
435 Also, ignore EXDEV errors as they are handled immediately after
436 (avoid printing out an error).
440 Mon Feb 12 15:50:24 CET 2007 Paolo Molaro <lupus@ximian.com>
442 * shared.c: exit if semaphores can't be created (bug #80616).
444 2007-02-01 Geoff Norton <gnorton@customerdna.com>
446 * collection.c: NetBSD doesn't define PTHREAD_STACK_MIN.
448 2007-01-26 Dick Porter <dick@ximian.com>
451 * sockets.c (_wapi_getsockopt): Windows seems to not reset
452 SO_ERROR values when they're read, contrary to the documentation.
453 Fixes the new issues raised in bug 79878 (example in C showing
454 winsock behaviour attached to that bug.)
456 2007-01-15 Mark Mason <mason@broadcom.com
458 * atomic.h: add locking primitives for MIPS.
460 2007-01-11 Dick Porter <dick@ximian.com>
462 * sockets.c (_wapi_connect): Don't do the SO_BROADCAST setting
463 here, do it in managed code instead.
464 (_wapi_getsockopt): SO_RCVTIMEO and SO_SNDTIMEO use struct
465 timeval, which has a microsecond field, not milliseconds.
466 (_wapi_setsockopt): ditto.
467 (_wapi_setsockopt): Halve the SO_SNDBUF and SO_RCVBUF values on
468 Linux, as the kernel doubles whatever we set.
469 (_wapi_socket): Save socket domain, type and protocol so it can be
471 (socket_disconnect): Implement socket disconnect (closing the
472 socket, but keeping the file descriptor.)
473 (wapi_disconnectex): A basic implementation of DisconnectEx().
474 (wapi_transmitfile): A very basic implementation of
476 (WSAIoctl): Implement the SIO_GET_EXTENSION_FUNCTION_POINTER
479 * socket-private.h (struct _WapiHandle_socket): Record socket
480 domain, type and protocol info so it can be duplicated later.
482 * sockets.h (WSAID_DISCONNECTEX,WSAID_TRANSMITFILE): Structures
483 and defines needed to look up the DisconnectEx() and
484 TransmitFile() functions by GUID.
486 * error.c (errno_to_WSA): Change ETIMEDOUT mapping to
487 WSAETIMEDOUT; add EDESTADDRREQ.
489 * io-layer.h: Need mswsock.h on windows now.
491 2007-01-04 Miguel de Icaza <miguel@novell.com>
493 * io-portability.c (find_file): Fix a coverity warning (scanning
496 2006-12-31 Miguel de Icaza <miguel@novell.com>
498 * io-portability.c (find_file): Do not abort if an empty filename
499 has been passed. This fixes the case where MONO_IOMAP=all would
500 assert if Directory.Exists ("") was called.
502 Mon Dec 18 14:54:37 CET 2006 Paolo Molaro <lupus@ximian.com>
504 * processes.c: moved a free on the error path.
506 Thu Dec 14 21:42:39 CET 2006 Paolo Molaro <lupus@ximian.com>
508 * processes.c: fixed a few memory leaks when executing
511 Mon Nov 27 13:12:17 GMT 2006 Paolo Molaro <lupus@ximian.com>
513 * atomic.h: fix arm compare and exchange (bug #78500).
515 2006-11-23 Dick Porter <dick@ximian.com>
517 * process-private.h (struct _WapiHandle_process): Add 'waited'
520 * processes.c (process_wait): Check the 'waited' parameter not the
521 signalled state when testing if a process has already been waited
522 for, as the child process itself may set signalled when exiting.
525 * wapi-private.h (_WAPI_HANDLE_VERSION): Bump shared data version
527 * shared.c: Now the shared data version has been incremented we
528 can set the counter semaphore initial value correctly
530 2006-11-22 Dick Porter <dick@ximian.com>
532 * processes.c (process_wait): Cope when the background process
533 reaper gets the process we were waiting for. Special case for
534 waiting for our own process to exit. Fixes bug 77736.
536 2006-11-17 Dick Porter <dick@ximian.com>
538 * processes.c: Fix const correctness and typos that caused memory
541 2006-11-17 Miguel de Icaza <miguel@novell.com>

544 thanks to Dick for pointing this out.
546 2006-11-16 Miguel de Icaza <miguel@novell.com>
548 * processes.c (ShellExecuteEx): If we fail to create a process in
549 ShellExecute, then try to use the xdg-open command, and if that
550 fails, try to use the gnome-open command,
552 Refactor the code so that we do not have to duplicate all this
553 code, but instead use a ucs2-aware version of the code to do
556 2006-11-13 Dick Porter <dick@ximian.com>
558 * io.c (_wapi_stat_to_file_attributes): If the file is a symlink
559 add the FILE_ATTRIBUTE_REPARSE_POINT flag. This is an attempt to
560 follow the specs for the windows symlink support, but will
561 probably have to be reworked when I have test data from a vista
562 machine. Fixes bug 79887.
564 2006-11-11 Miguel de Icaza <miguel@novell.com>
566 * handles.c (CloseHandle): Cope here with the new value
567 INVALID_HANDLE_VALUE set on handles.
569 * processes.c (CreateProcess): Initialize the value of hThread to
570 be INVALID_HANDLE_VALUE on failure, not to be NULL. Improvement
573 2006-11-09 Dick Porter <dick@ximian.com>
575 * sockets.c (_wapi_select): Do some sanity checking on the
576 fd_sets, to avoid file descriptors > FD_SETSIZE.
577 (_wapi_FD_CLR, _wapi_FD_ISSET, _wapi_FD_SET): Avoid file
578 descriptors > FD_SETSIZE.
580 2006-10-27 Dick Porter <dick@ximian.com>
582 * io.c (GetFileAttributes): Force symlinks to directories to be
583 returned as a regular file. Fixes bug 79733.
585 2006-10-18 Miguel de Icaza <miguel@novell.com>
587 * io-portability.c (find_in_dir): First string dup, then closedir.
589 2006-10-12 Dick Porter <dick@ximian.com>
591 * processes.c (_wapi_process_reap): Unref a process handle if we
592 reaped it, found by Zoltan. Fixes bug 79286.

617 * wait.c: Add an alertable parameter to the wait routines.
619 2006-10-06 Miguel de Icaza <miguel@novell.com>
621 * io-portability.c (find_file): Rename from
622 MONO_IO_PORTABILITY_HELP to MONO_IOMAP.
624 2006-10-03 Dick Porter <dick@ximian.com>
627 * io-portability.c: Optional portability helpers and wrapped
628 system calls to try to cope with windows filenames in
631 * io.c: Use the wrapped system calls
633 2006-09-01 Zoltan Varga <vargaz@gmail.com>
635 * critical-sections.h critical-sections.c: Make Enter/LeaveCriticalSection a macro
636 since they are perf critical.
638 * atomic.h: Applied patch from Jakub Boqusz <qboosh@pld-linux.org>.
639 Add atomic ops implementation for alpha.
641 2006-08-11 Dick Porter <dick@ximian.com>
643 * processes.c (_wapi_process_reap): Avoid a deadlock by setting
644 process termination details in an outer loop, not the
645 _wapi_search_handle() one.
647 2006-08-10 Dick Porter <dick@ximian.com>
649 * threads.c (_wapi_thread_queue_apc)
650 (_wapi_thread_dispatch_apc_queue): Use a process-local mutex here
651 instead of the cross process semaphore. We already check that
652 access to the APC queue is within the owning process so there's no
653 need to protect from other processes. Avoids a global deadlock
654 when a thread is aborted while it holds the handle semaphore
656 (_wapi_thread_apc_pending): Hide an annoying message which can
657 happen if a thread handle has been blown away at process shutdown
658 while it is in an alertable wait.
660 Both problems seen while shutting down monodevelop.
662 2006-07-25 Dick Porter <dick@ximian.com>
664 * shared.c (_wapi_shm_file): Remove '/' characters from the uname
665 results. Fixes bug 78917.
667 2006-07-20 Dick Porter <dick@ximian.com>
669 * threads.c (_wapi_thread_set_termination_details): Improve the
670 test for already-disposed thread handles, and hold the lock around
671 the mutex abandoning.
673 2006-07-17 Dick Porter <dick@ximian.com>
675 * processes.c (CreateProcess): Don't change directory unless a new
676 one has been specified. Fixes bug 78751.
678 2006-07-06 Dick Porter <dick@ximian.com>
680 * io.c (_wapi_stat_to_file_attributes): Do a better job at
681 figuring out the file attributes
682 (_wapi_set_last_path_error_from_errno): New helper function to
683 turn errno into w32 error codes that handles the differences
684 between file and directory errors
685 (file_setendoffile): Try turning off the extra write used to
686 extend files, because we probably don't need it on any modern
687 platform. If it is needed though, we also need to lseek the file
689 (CreateFile): Treat character-special devices as a console handle,
690 because they can't be seeked
691 (CopyFile): If fail_if_exists is set, then the destination needs
692 to be opened with O_EXCL
693 (CopyFile): If fail_if_exists is not set and the destination
694 already exists, then we should set the ERROR_ALREADY_EXISTS error
695 even though we return success
696 (stdhandle_create): STD_INPUT_HANDLES cannot be written to
697 (GetStdHandle): Rework without using mono_once, so console handles
698 can be properly closed and reopened.
699 (mono_io_scandir): Only override errno with EACCES when the
700 directory actually exists
701 (FindFirstFile): Set ERROR_FILE_NOT_FOUND when no files are
703 (FindClose): Cope with NULL handles
704 (CreateDirectory): When the target already exists, just return an
705 error. It's the caller's job to figure out what to do.
706 (SetCurrentDirectory): Cope with a NULL path
707 (RemoveDirectory, GetFileAttributes, GetFileAttributesEx,
708 SetFileAttributes, FindFirstFile, DeleteFile, MoveFile, CopyFile,
709 CreateFile): Set path error correctly
711 * handles.c (CloseHandle): Kludge to try and cope with passing a
714 * error.h: Add NO_ERROR as an alternative to ERROR_SUCCESS
716 * uglify.h: Added some more typedefs
718 2006-07-05 Dick Porter <dick@ximian.com>
720 * io.c (GetFileAttributes, GetFileAttributesEx): Cope with
721 dangling symlinks. Fixes bug 78664.
723 2006-06-23 Dick Porter <dick@ximian.com>
725 * handles.c (handle_cleanup):
726 * threads.c: Clean up threads properly when we're forcibly
727 removing the handle entries from the shared file in
728 handle_cleanup(). Fixes bug 78241, for real this time.
730 2006-06-15 Neale Ferguson <neale@sinenomine.net>
732 * atomic.h: More tinkering with InterlockedExchange/InterlockedCompareExchange
735 2006-06-14 Neale Ferguson <neale@sinenomine.net>
737 * atomic.h: Fix atomic exchange pointer operations for s390x - these
738 were broken as they used 32-bit instructions rather than their 64-bit
741 2006-06-14 Dick Porter <dick@ximian.com>
743 * processes.c: Don't run the atexit handlers when bailing out
746 2006-06-14 Dick Porter <dick@ximian.com>
748 * wait.c: Fix stupid typo shown up by gcc 4.1.1, = not ==
756 * collection.c: Fix a bunch of signed/unsigned warnings from gcc
759 2006-06-09 Neale Ferguson <neale@sinenomine.net>
761 * atomic.h: Fix atomic operations for s390x (not really broken
762 but changed to use full 64-bit opcodes).
764 2006-05-24 Dick Porter <dick@ximian.com>
766 * processes.c (process_set_current): Don't take an extra reference
767 if we have to create our own process handle. Fixes bug 78241
770 * threads.c (_wapi_thread_signal_self): Renamed from
771 _wapi_thread_abandon_mutexes, also sets the thread state to
772 signalled and drops a reference. Called by the runtime when the
773 main thread cleans itself up.
775 * handles.c (handle_cleanup): As a last resort, unref every shared
776 handle as the process is now exiting.
778 2006-05-16 Dick Porter <dick@ximian.com>
780 * processes.c (process_set_termination_details): Unref the handle
781 when we've stored the exit details. Fixes the rest of 78241.
783 2006-05-12 Dick Porter <dick@ximian.com>
785 * threads.c: Implement pseudo handles, making GetCurrentThread()
786 match MS behaviour. Notice when attached threads exit, and unref
787 the handle. Fix usage of GetCurrentThread() in other places.
789 * handles.c (DuplicateHandle): Implement a basic form of
792 * wait.c: Fix usage of GetCurrentThread() throughout, and cope
795 2006-04-26 Miguel de Icaza <miguel@novell.com>
797 * io.c (file_close): Oops, do not use DeleteFile which expects
798 unicode, instead use unlink directly
800 Add support for the new FileOptions bits on .NET 2.0.
802 It might be good if Dick reviews these changes.
804 * io.c (file_close): If DeleteOnClose is set, then delete the file
806 (CreateFile): Do not support encryption per user.
808 If posix_fadvise exists, pass hints on sequential scan and random
809 access. Did not figure out what WRITE_THROUGH maps to.
811 2006-04-26 Dick Porter <dick@ximian.com>
813 * sockets.c (WSAIoctl): Check the output buffer is valid before
816 * handles.c (_wapi_search_handle): Set shared pointer if we find a
817 shared handle that has been already opened.
819 2006-04-21 Dick Porter <dick@ximian.com>
821 * threads.c (GetCurrentThread): Reference the handle if we return
822 an already-known thread.
824 2006-04-07 Dick Porter <dick@ximian.com>
826 * processes.c: Fix build for older glib.
828 2006-04-06 Dick Porter <dick@ximian.com>
830 * processes.c (CreateProcess): Add a reference to the child
831 process' handle, so it won't be destroyed if this process closes
832 its copy of the handle. Fixes bug 77393.
834 * processes.c (process_set_current): Fall through to creating a
835 new one if the handle lookup fails.
837 * processes.c (_wapi_process_signal_self):
838 * handles.c (handle_cleanup): The process is exiting, so set the
839 handle state for this process to signalled. This should let other
840 non-related processes wait for this handle.
842 * handles.c (_wapi_search_handle): Don't search shared handles in
845 * collection.c (collection_thread): No need to do a collection
846 scan straight away, do the waiting first.
848 2006-04-06 Dick Porter <dick@ximian.com>
850 * shared.c: Fix parameters in semctl () call.
852 2006-03-28 Zoltan Varga <vargaz@gmail.com>
854 * atomic.h atomic.c: Applied patch from David S. Miller
855 <davem@davemloft.net>: Reimplement Interlocked* primitives on sparc
856 using CAS/CASx when __GNUC__, else we will fall back to the generic
859 2006-03-27 Dick Porter <dick@ximian.com>
861 * shared.c (_wapi_shm_file_open): Break out of a loop if the
862 shared file is smaller than expected. (We loop a few times in
863 case another process is in the middle of creating the file.)
865 2006-03-22 Dick Porter <dick@ximian.com>
870 * shared.c: Delete the semaphores and shared files when the last
871 process has finished with them
873 2006-03-15 Dick Porter <dick@ximian.com>
881 * threads.c: Explicitly initialise the handle ops struct
883 2006-03-14 Dick Porter <dick@ximian.com>
888 * handles.c: Add a 'prewait' stage to the handle waiting, to give
889 waiting threads a chance to check for bogus states before
892 * mutexes.c (namedmutex_prewait): Use the prewait stage to check
893 for named mutexes that have been abandoned in a locked state (eg
894 if a process exited abnormally while owning the mutex) and
895 override it if needed.
897 2006-03-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
899 * wait.c: speed up WaitFor* when the timeout is 0.
901 2006-03-03 Dick Porter <dick@ximian.com>
903 * processes.c (ShellExecuteEx): Cope when some of the parameters
906 2006-02-27 Dick Porter <dick@ximian.com>
910 * threads.c: Comparing pthread_t with == is not portable, so use
913 Thu Feb 23 18:47:20 GMT 2006 Paolo Molaro <lupus@ximian.com>
915 * *.h, *.h: patch from Dick to make Linuxthreads systems work again.
917 2006-02-22 Dick Porter <dick@ximian.com>
920 * threads.c: There's no need to use the timed-thread support code
921 any more, as we aren't using the timed join. This greatly
922 simplifies thread setup, and fixes a memory leak (bug 77521).
924 Don't bother to store thread IDs in a hash table, use TLS instead.
925 The one case that needs to look up the handle of a different
926 thread (OpenThread()) can do the extra work itself. Fixes bug
929 * handles.c (_wapi_search_handle): Add a reference when returning
930 a private handle (shared handles are already reffed.)
932 2006-02-17 Dick Porter <dick@ximian.com>
935 * handles.c: Check handle values passed to array lookups. Fixes
938 2006-02-09 Dick Porter <dick@ximian.com>
940 * threads.c: Cope with the problems caused by attaching already
941 existing threads - they don't get the infrastructure to clean up
942 after themselves, especially the ID to handle hash. This fixes
945 2006-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
947 * shared.c: use MONO_SHARED_HOSTNAME as a substitute for gethostname()
948 when creating the shared files in the .wapi directory. Fixes bug #77371.
950 2006-02-02 Martin Baulig <martin@ximian.com>
952 * threads.c: Removed the `WITH_INCLUDED_LIBGC' section; it has
953 never been used so far.
955 * timed-thread.h (TimedThread): Removed the `stack_ptr' field; it
956 has only been used by the removed code.
958 2006-01-03 Neale Ferguson <neale@sinenomine.net>
960 * atomic.h: Correct s390x definitions and eliminate compiler warnings.
962 2006-01-03 Sebastien Pouliot <sebastien@ximian.com>
964 * io.c: Patch _wapi_stat_to_file_attributes against bug #76966, where
965 sockets could be considered as directory.
967 2005-12-23 Dick Porter <dick@ximian.com>
971 * semaphores.c: Implement OpenSemaphore
974 * mutexes.h: Implement OpenMutex
980 * event-private.h: Implement named events. Implement OpenEvent.
982 2005-12-15 Dick Porter <dick@ximian.com>
984 * processes.c (CreateProcess): The pipe-based cross-process
985 exclusion technique was trying to write NULL buffers when appname
986 was NULL (eg when coming from ShellExecuteEx,) which usually
987 succeeded even though EFAULT was returned - but sometimes it
988 failed. This meant that the child process could block forever on
989 the pipe read. Replace it with the simpler shared handle
990 semaphore protection used everywhere else. This showed up with
991 the test case in bug 76684.
993 Tue Dec 13 11:41:49 GMT 2005 Paolo Molaro <lupus@ximian.com>
995 * shared.c: fallback to private mmap when shared mmap doesn't work
998 2005-12-06 Dick Porter <dick@ximian.com>
1002 * semaphore-private.h:
1003 * semaphores.c: Implement named semaphores
1005 2005-11-24 Dick Porter <dick@ximian.com>
1007 * processes.c (GetProcessId): Implement GetProcessId()
1009 2005-11-17 Dick Porter <dick@ximian.com>
1012 * processes.c: Implement ShellExecuteEx as a wrapper around
1015 2005-11-11 Dick Porter <dick@ximian.com>
1017 * threads.c: Give mutex abandoning its own exported function, so
1018 it can be called when the runtime is cleaning up.
1020 * handles.c (_wapi_search_handle_namespace): Do a handle
1021 collection befre starting to check namespace strings, so that any
1022 stale cruft gets removed.
1024 2005-11-11 Dick Porter <dick@ximian.com>
1026 * threads.c: Move thread handles back into the shared space.
1028 * handles.c (_wapi_handle_unref): Add support for shared handles
1029 with close() handlers
1031 2005-11-04 Dick Porter <dick@ximian.com>
1033 * sockets.c (ioctlsocket): Use select instead of if to avoid a
1034 type promotion problem on 64bit freebsd. Based on patch by Lou
1035 Kamenov <kamenovl@gmail.com>, fixes bug 76447.
1037 2005-11-04 Dick Porter <dick@ximian.com>
1039 * io.c (file_write): Only do the file locking if
1040 MONO_STRICT_IO_EMULATION is set.
1042 2005-10-21 Dick Porter <dick@ximian.com>
1045 * handles.c (_wapi_lookup_handle): Cope when the shared part of a
1046 handle has been deleted.
1047 (_wapi_handle_unref): And when the deleted shared part is pointed
1048 to as a handle is deleted
1050 2005-10-20 Dick Porter <dick@ximian.com>
1052 * processes.c (process_set_current): If the expected process
1053 handle slot doesn't contain the correct pid, create a new handle.
1055 * handles.c (_wapi_search_handle): When the search doesn't find
1056 anything, return failure instead of the last handle we looked at.
1057 (_wapi_handle_ref, _wapi_handle_unref): Don't try to ref or unref
1058 unused handles (makes tracking refcounting bugs easier.)
1060 2005-10-19 Dick Porter <dick@ximian.com>
1063 * handles-private.h:
1067 * collection.c (_wapi_handle_collect): Remove the shared handle
1068 indirection layer, and use locking instead. Delete other
1069 complexity that is no longer needed. Refcount shared handles and
1070 delete them when needed, but keep the timestamps so that orphaned
1071 handles will be cleaned up eventually.
1073 * shared.c (_wapi_shm_file): Add processor, OS and struct size
1074 info to the shared file names, to cope with dual-boot and 32/64bit
1075 size issues. Fixes bug 75839.
1077 * wait.c (WaitForMultipleObjectsEx): No need to distinguish
1078 between shared handles and private, as the wait functions cope
1079 with both together now.
1081 2005-10-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1083 * io.c: removed NO_SIGPIPE macro.
1084 * sockets.c: no need for MSG_NOSIGNAL or ignoring SIGPIPE.
1086 2005-10-11 Dick Porter <dick@ximian.com>
1088 * sockets.c (_wapi_getsockopt): Translate SO_ERROR results into
1091 * error.c (errno_to_WSA): Don't return a bogus error if someone
1092 asks to translate errno 0.
1094 2005-10-11 Dick Porter <dick@ximian.com>
1096 * handles.c: Fix several race conditions
1098 2005-10-11 Miguel de Icaza <miguel@novell.com>
1100 * io.c: no need to block SIGPIPE anymore, as it is ignored.
1102 2005-10-05 Dick Porter <dick@ximian.com>
1104 * threads.c (_wapi_thread_own_mutex, _wapi_thread_disown_mutex):
1105 Keep a reference to mutexes owned by threads, so they won't be
1106 destroyed prematurely. Fixes dotmsnclient crash.
1108 2005-09-26 Sebastien Pouliot <sebastien@ximian.com>
1110 * io.c: Apply patch from #76192 (Can't write files past 2gb on AMD64
1111 (x86_64)) for Brion on IRC (Dick approved it).
1113 2005-09-23 Dick Porter <dick@ximian.com>
1115 * processes.c: Don't wait for processes that have already been
1116 signalled; also fix typo.
1118 * handles.c: Improve locking inside new handle and handle
1119 searching functions.
1121 2005-09-20 Dick Porter <dick@ximian.com>
1124 * processes.c: Periodically waitpid for known process IDs. Fixes
1127 2005-09-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1130 (CreateFile): if the file is a named pipe, treat the handle as a pipe,
1131 not as a file. Fixes bug #76075.
1133 2005-08-27 Zoltan Varga <vargaz@gmail.com>
1135 * atomic.h: Add support for intel icc.
1137 2005-08-25 Zoltan Varga <vargaz@gmail.com>
1139 * io-layer.h: Include winbase.h not WinBase.h.
1141 2005-08-19 Dick Porter <dick@ximian.com>
1143 * threads.c, threads.h, thread-private.h: Use a gsize to store the
1144 thread ID, so it can hold a 64 bit value if needed.
1146 2005-07-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1148 * error.c: map ENOENT to WSAECONNREFUSED. It might happen when
1149 connecting to unix sockets. Closes bug #75632.
1151 2005-07-05 Dick Porter <dick@ximian.com>
1153 * io.c: Make sure SIGPIPE is ignored when calling write(2).
1154 Prevents the runtime exiting when writing to a closed pipe,
1157 2005-06-30 Dick Porter <dick@ximian.com>
1159 * shared.c (_wapi_shm_semaphores_init): Add some helpful error
1160 messages when semget () fails due to lack of resources.
1162 2005-06-21 Dick Porter <dick@ximian.com>
1167 * threads.c: Keep a list of owned mutexes in each thread handle,
1168 so that it is easier to abandon them when the thread exits.
1169 Removes a bottleneck when multiple threads are finishing in
1172 2005-06-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1174 * io.c: (GetLogicalDrives) when a bogus line is read, don't leak memory.
1175 When the buffer has not enough space, close the file before returning.
1177 2005-06-09 Duncan Mak <duncan@novell.com>
1179 * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to
1180 all public headers. Fixes #74919.
1182 2005-05-30 Zoltan Varga <vargaz@freemail.hu>
1184 * atomic.h: Add IA64 atomic ops.
1186 2005-05-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1188 * processes.c: make ExitCode be valid even if the user didn't call
1189 WaitForExit() and is just polling on HasExited.
1191 2005-05-17 Dick Porter <dick@ximian.com>
1193 * io.c (file_getfilesize): Clear the error value, so that files
1194 with sizes with the low bits 0xFFFFFFFF can be distinguished from
1197 2005-05-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1199 * shared.c: forgot to ignore a warning.
1201 2005-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1203 * shared.c: don't display warnings after reboots.
1205 2005-05-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1207 * sockets.c: on windows, getsockopt/setsockopt for send/receive timeout
1208 use an integer in milliseconds. We were using a struct timeval.
1210 2005-05-06 Dick Porter <dick@ximian.com>
1212 * handles-private.h:
1219 * collection.h: Use SysV semaphores for managing access to the
1220 shared memory - in return for the ludicrous api we get
1221 synchronisation primitives that can be cleaned up by the kernel
1222 even when a process quits unexpectedly. This removes the
1225 2005-05-05 Lluis Sanchez Gual <lluis@novell.com>
1227 * handles.c: Always use polling in the waits, since
1228 mono_cond_timedwait can't be interruped by the thread abort signal.
1230 2005-04-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1232 * events.c: calling Set on AutoResetEvent several times has the same
1233 effect as calling it only once if no thread is waiting for it.
1235 2005-04-29 Dick Porter <dick@ximian.com>
1237 * processes.c (EnumProcesses): Use a GArray instead of a GPtrArray
1238 now it's storing pids not handles, also fixes memory leak caused
1239 by unclear glib documentation.
1241 * sockets.c (WSACleanup): Remove unused variable
1243 2005-04-29 Dick Porter <dick@ximian.com>
1245 * handles.c (_wapi_handle_check_share_by_pid): For systems that
1246 don't have file descriptor info in /proc check that the original
1247 opener of a file is still there, if a share violation would
1250 2005-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1253 * handles-private.h: added _wapi_handle_forecch that loops through all
1254 the handles and call a callback function when a handle of the given
1257 * sockets.c: no need to keep open sockets in an array, as we have them
1258 in the handles structure.
1262 2005-04-28 Dick Porter <dick@ximian.com>
1264 * processes.c: Cope with handles that are only around for as long
1265 as the search is running. If we're searching for process handles,
1266 check to see if the process is still running and signal it if not.
1268 * handles.c (_wapi_search_handle): Search in the shared space as
1269 well. Fixed bug 74752.
1272 * handles.c (_wapi_handle_new_from_offset):
1273 _wapi_handle_new_for_existing_ns () was doing exactly the same as
1274 this, so deleted it.
1276 2005-04-26 Dick Porter <dick@ximian.com>
1278 * handles.c: Fix stupid thinko where if a new shared handle is
1279 created but a collection was needed to free some space, it
1280 returned an error anyway. Should fix the messages shown in bug
1283 2005-04-25 Dick Porter <dick@ximian.com>
1285 * handles.c (_wapi_handle_check_share): Only consider mono
1286 processes when looking to see if a file is still being held open,
1287 while checking share permissions.
1289 2005-04-25 Dick Porter <dick@ximian.com>
1293 * wapi-private.h (struct _WapiHandleOps):
1294 * handles.c (_wapi_handle_unref): When destroying handles, save
1295 the handle data and call the close function only after the array
1296 slot has been cleared. This prevents race conditions with file
1297 descriptors, fixing bug 74713.
1299 * mutexes.c: Delete the handle close functions, they didn't do
1302 * error.c (_wapi_get_win32_file_error): Add a mapping for EINTR so
1303 the "Unknown error" g_warning doesn't get displayed.
1305 2005-04-25 Dick Porter <dick@ximian.com>
1308 * threads.c: Make thread handles process-private for now to take
1309 some of the space pressure off the shared memory, while I work on
1312 2005-04-21 Dick Porter <dick@ximian.com>
1314 * handles.c (_wapi_handle_check_share): Make sure there is a "fd"
1315 dir in /proc before blowing away handle info. Fixes bug 74649.
1317 2005-04-21 Dick Porter <dick@ximian.com>
1319 * wait.c (WaitForMultipleObjectsEx): Implement special waits
1321 * handles.c (_wapi_handle_wait_signal_poll_share): Don't return a
1322 timeout, just wait briefly for the private signals and let the
1323 waiting thread test again. This prevents us missing shared
1326 2005-04-21 Dick Porter <dick@ximian.com>
1328 * collection.h (_WAPI_HANDLE_COLLECTION_EXPIRED_INTERVAL): Reduce
1329 the time before a slot is considered too old and deleted. This is
1330 a workaround while I come up with a proper fix.
1332 2005-04-21 Dick Porter <dick@ximian.com>
1337 * handles.c (_wapi_handle_new): Turn assertions into errors.
1339 * collection.c (_wapi_handle_collect): Use symbols not magic
1340 numbers for timeout values
1342 2005-04-19 Dick Porter <dick@ximian.com>
1346 * handles.c (_wapi_handle_count_signalled_handles)
1347 * handles-private.h (_wapi_handle_shared_lock_handle): Use new
1348 shared handle locks in critical sections.
1350 * handles.c (_wapi_handle_new_for_existing_ns): Reuse old handles
1351 if there is already one there.
1353 * handles.c (_wapi_handle_ref): It was possible for a process to
1354 exit before getting around to updating shared handle timestamps,
1357 Tue Apr 19 16:25:47 CEST 2005 Paolo Molaro <lupus@ximian.com>
1359 * threads.c: fix lookup of the thread id in the has table:
1360 always use the id value, not the pointer to the id.
1362 2005-04-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1364 * handles.c: fix handle returned in _wapi_handle_search_handle. Dick
1367 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1369 * io-layer/sockets.c: FIONBIO with a TRUE argument means we want
1370 non-blocking IO, not the other way around.
1372 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1376 * handles-private.h: GetFileType wasn't checking if we have memory
1377 allocated for the handle before dereferencing it. Fixes a FileStream
1380 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1384 * handles-private.h: we were calling g_renew to expand the handle array,
1385 but that might move the memory and we might have pthread conditions or
1386 mutexes in the original memory area that are being used. Now instead of
1387 expanding an existing array, we just create new ones and keep a list of
1388 them. Access to _wapi_private_handles had to be modified accordingly.
1390 2005-04-15 Dick Porter <dick@ximian.com>
1392 * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN
1394 2005-04-14 Raja R Harinath <rharinath@novell.com>
1396 * wapi-private.h: Remove reference to 'daemon-private.h'.
1398 Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro <lupus@ximian.com>
1400 * atomic.h: applied patch from mass@akuma.org (David Waite)
1401 to fix InterlockedExchangeAdd.
1402 Fixed a few other functions, including InterlockedCompareExchange()
1403 which was miscompiled by gcc with optimizations enabled.
1405 2005-04-13 Dick Porter <dick@ximian.com>
1407 * io.c (share_check):
1408 * handles.c (_wapi_handle_check_share): Refine the file check so
1409 that sharing violations within the same process don't cause
1412 2005-04-13 Dick Porter <dick@ximian.com>
1414 * io.c (FindFirstFile): Fix bugs introduced with the merge (bug
1417 2005-04-12 Dick Porter <dick@ximian.com>
1419 The daemon-less io-layer. Extensive lowlevel changes in
1420 handles.c, requiring some corresponding changes in other files
1421 calling these functions. Private_foo structures have been
1424 File descriptor handling differences account for most of the
1425 changes in io.c and sockets.c.
1429 * mutexes.c: Named mutexes are now a distinct type.
1430 * atomic.h: Fix a PPC uninitialised variable warning.
1431 * wait.c: Check conditions before waiting on a condition variable.
1432 * processes.c: Handle process fork and wait without a daemon
1433 (though this has the limitation of only being able to wait for
1436 2005-04-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1443 * sockets.h: removed dead code that deals with async IO.
1445 2005-03-30 Zoltan Varga <vargaz@freemail.hu>
1447 * atomic.c (InterlockedIncrement): Fix fallback implementation of
1448 InterlockedIncrement and InterlockedDecrement. Fixes #74228.
1450 2005-03-29 Sebastien Pouliot <sebastien@ximian.com>
1452 * io-layer.h: Add required header files for compiling with VS.NET.
1454 2005-03-17 Miguel de Icaza <miguel@novell.com>
1456 * io.c: don't fail on NFS when there are no more locks available.
1458 2005-03-09 Dick Porter <dick@ximian.com>
1460 * error.c (_wapi_get_win32_file_error): ENFILE and EMFILE should
1461 map to ERROR_TOO_MANY_OPEN_FILES, not ERROR_NO_MORE_FILES. Fixes
1464 2005-03-09 Dick Porter <dick@ximian.com>
1466 * daemon.c (process_process_fork): Initialise the handle data
1467 before using it in the error case. This is probably the error
1468 we're working around in the previous change. Spotted by Taru Jain
1469 <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.
1471 2005-03-07 Dick Porter <dick@ximian.com>
1473 * daemon.c: It looks like g_shell_parse_argv() can return
1474 argv[0]=NULL somehow, yet still not give an error. Make sure we
1475 don't pass NULL to strrchr(), working around a segfault that
1476 showed up on ZLM testing.
1478 2005-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1480 * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is
1481 the expected error code showed by the test case in bug #73053.
1483 2005-02-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1485 * io.c: another leftover.
1487 Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1489 * io.c: fixed logic in checking errno in rev 40815.
1491 Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1493 * threads.c: we don't depend on the GC checking tls
1495 * processes.c: remove unused ref to GC headers.
1497 Thu Feb 17 19:57:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1499 * io.c: remove _wapi_thread_cur_apc_pending () checks
1500 when the siscall should return immediatly and handle
1501 the case when a syscall is interrupted without
1502 erroring out, but returning a 0 read/write if possible.
1503 Still the cases of read from file need to be handled.
1505 Tue Feb 8 18:28:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1507 * threads.c: make people test with 1 MB stack per thread.
1509 2005-01-17 Dick Porter <dick@ximian.com>
1511 * timefuncs.h: Make WapiFileTime endian-aware, as it's often
1512 cast to and from 64bit ints. Fixes bug 71213.
1514 2005-01-11 Dick Porter <dick@ximian.com>
1516 * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
1519 Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>
1521 * atomic.h: Fix functions on s390.
1523 Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>
1525 * atomic.h: fix some functions on ppc (tests/interlocked.cs).
1527 2005-01-10 Dick Porter <dick@ximian.com>
1529 * misc.c (_wapi_calc_timeout): Guard against overflow when
1530 calculating timeouts. This makes waiting with a large
1531 (Int32.MaxValue) timeout not return immediately.
1533 2004-12-23 Ben Maurer <bmaurer@ximian.com>
1535 * io.c (io_ops): make this `const' so it is shareable (well, only
1536 really shareable if it is statically linked...)
1538 Mon Dec 20 11:58:33 CET 2004 Paolo Molaro <lupus@ximian.com>
1540 * threads.c, threads.h: add accessor to get the pthread_key_t for
1543 2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1545 * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS
1546 if it exists and is not the same as 'src'.
1548 2004-12-01 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1550 * atomic.h : Fix InterlockedCompareExchange for s390/s390x.
1552 2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1554 * processes.c: unquote the cmd path, allow for ' or " when quoting and
1555 pass the quoted program name to the daemon, otherwise the call to
1556 g_shell_unquote in the daemon will break things up.
1558 2004-10-14 Dick Porter <dick@ximian.com>
1560 * sockets.c (_wapi_accept): Revert the previous change. We now
1561 set the accepted socket to have the same blocking status as the
1562 listening socket in managed code. This follows MS behaviour.
1564 2004-10-14 Dick Porter <dick@ximian.com>
1566 * sockets.c (_wapi_accept): On Darwin, make sure a newly
1567 accept()ed socket is blocking. Fixes bug 67355, patch by
1568 grompf@sublimeintervention.com.
1570 2004-10-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1572 * system.c: check the number of online processors instead of the
1573 existing ones. Sanitize return value if it's an error.
1575 2004-10-03 Ben Maurer <bmaurer@ximian.com>
1577 * system.c: Add support for getting the # of cpus.
1579 2004-09-28 Dick Porter <dick@ximian.com>
1581 * io.c (pipe_close_private): Fix one small typo in the last change
1582 that totally hosed process creation with redirected pipes.
1584 2004-09-24 Dick Porter <dick@ximian.com>
1591 * handles-private.h: Cope when a file descriptor is reused while
1592 the handle that thought it owned it is still referenced, instead
1593 of asserting. Probably fixes bug 66479, though we've been unable
1596 2004-09-09 Dick Porter <dick@ximian.com>
1599 * io.c: Set error codes everywhere.
1601 2004-09-06 Dick Porter <dick@ximian.com>
1603 * handles.c (_wapi_handle_unref): Reset the private record's type
1604 (CloseHandle): Check for a fd mapping failure, and return FALSE.
1605 (_wapi_handle_process_fork): Fix long-standing bug in checking
1606 handle return values. Also do the required bookkeeping with the
1607 new process's handles.
1609 * daemon.c: When creating a new process's handles, check whether
1610 the shared space needs to be increased
1612 2004-09-05 Zoltan Varga <vargaz@freemail.hu>
1614 * shared.c (_wapi_shm_file): Fix leaking of filename.
1616 2004-08-19 Dick Porter <dick@ximian.com>
1618 * handles.c (_wapi_handle_count_signalled_handles): Fix thinko
1619 introduced with the fd offset stuff: unlock handles properly when
1620 backing off. Fixes the monologue hang at exit.
1622 2004-08-18 Dick Porter <dick@ximian.com>
1625 * io.c: Check that new fds fit in the table, return error if not
1627 * daemon.c (_wapi_daemon_main):
1628 * handles.c (shared_init): Have all processes agree on a size for
1631 2004-08-17 Dick Porter <dick@ximian.com>
1633 * daemon.c (process_new):
1634 * handles.c (_wapi_handle_new_internal): Cope when the space
1635 reserved for file descriptors is larger than the shared segment
1636 size. Fixes the crash reported when running mono under gdb on
1639 2004-08-16 Dick Porter <dick@ximian.com>
1643 * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
1644 error checking with passed-in file descriptors.
1646 2004-08-11 Dick Porter <dick@ximian.com>
1649 * io.c: Returned handle values are the file descriptor the handle
1653 * handles-private.h:
1654 * daemon.c: Reserve the range of handles that can have the same
1655 values as file descriptors. These won't be used, but the values
1656 will be used as file, console, pipe or socket handles. The fd to
1657 handle mapping is done internally and is invisible to users.
1660 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
1661 reserve a chunk of handle space.
1663 2004-08-04 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1665 * atomic.h: add support for 64-bit S/390
1667 2004-07-22 Dick Porter <dick@ximian.com>
1670 * threads.c: Move the destruction of the internal thread data to
1671 after the thread has been joined. Fixes bug 61418.
1673 2004-07-14 Dick Porter <dick@ximian.com>
1675 * wait.c (test_and_own): When not waiting for all handles to
1676 become signalled, only own and return the lowest. All the
1677 documentation suggests that the old way was correct, but
1678 experimentation shows it actually works like this. Patch by
1679 Sébastien Robitaille
1680 (sebastien.robitaille@croesus.com), fixes bug 61511.
1682 2004-07-09 Ben Maurer <bmaurer@ximian.com>
1684 * threads.c: register roots for gc
1686 2004-07-08 Dick Porter <dick@ximian.com>
1688 * io.c (file_seek): If there is a high 32bit offset part, make
1689 sure the low part isn't sign-extended. Set error codes when
1690 returning failure. Fixes bug 61131.
1692 2004-07-06 Dick Porter <dick@ximian.com>
1694 * io.c (file_setfiletime): Check for underflow when converting to
1695 time_t values. Set error codes when returning failure. Fixes bug
1698 2004-07-05 Dick Porter <dick@ximian.com>
1700 * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable.
1702 * daemon.c (unref_handle): Only destroy a handle if all processes
1703 have released it, not just the current one. Fixes bug 60887.
1705 2004-06-30 Zoltan Varga <vargaz@freemail.hu>
1707 * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
1708 to prevent warnings.
1710 2004-06-24 Dick Porter <dick@ximian.com>
1712 * mutexes.c: Indicate when a named mutex was reused
1714 2004-06-24 Dick Porter <dick@ximian.com>
1716 * threads.c (SuspendThread):
1717 * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a
1718 while loop. See bug 58161.
1720 Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro <lupus@ximian.com>
1722 * io.c: don't use sharemode for on-disk file permissions: it's used
1723 for shared access to the open file.
1725 2004-06-22 Dick Porter <dick@ximian.com>
1727 * events.c (CreateEvent): When creating an auto-reset event that
1728 is initially owned, make sure the set count starts at 1.
1730 2004-06-18 Dick Porter <dick@ximian.com>
1733 * events.c: Auto-reset events need to release one thread for each
1734 time SetEvent() is called. Fixes bug 41292.
1738 * mutexes.c: Scan for mutexes that are still locked by a thread
1739 when it exits. Fixes the MS demo app linked by bug 41292.
1741 * wait.c (test_and_own): Make sure a handle is signalled before it
1744 2004-06-16 Dick Porter <dick@ximian.com>
1746 * timed-thread.c: Call the thread cleanup exit routine before taking
1747 the join mutex, because this could deadlock if another thread tries
1748 to join in the meantime. This fixes the hang-at-exit problem seen
1751 2004-06-03 Lluis Sanchez Gual <lluis@ximian.com>
1753 * threads.c: Implemented SleepEx.
1754 * threads.h: Fixed SleepEx signature.
1756 2004-06-03 Miguel de Icaza <miguel@ximian.com>
1758 * threads.c: When running under valgrind, do not allocate too much
1759 stack, as Valgrind default is 1 meg.
1761 2004-05-27 Dick Porter <dick@ximian.com>
1764 * io.c: Implemented LockFile() and UnlockFile()
1766 2004-05-21 Dick Porter <dick@ximian.com>
1768 * io.c (CreateFile): Check for existing share modes when opening
1772 * handles-private.h:
1773 * daemon-messages.h:
1774 * daemon.c: Maintain a hash of file share modes, keying on device
1775 and inode (to cope with symlinks.)
1777 2004-05-20 Lluis Sanchez Gual <lluis@ximian.com>
1779 * daemon-messages.c: Retry if the communication with the daemon is
1780 interrupted by a signal.
1781 * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped.
1782 Only return an error in this case if there is something in the apc queue
1783 (which means that it is an interruption requested by the "user").
1784 * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as
1785 true since the wait is small.
1786 * shared.c: Retry write calls when interrumped by a signal.
1787 * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which
1788 returns TRUE if there are pending asynchronous calls (APC) for the
1789 provided thread. Also added _wapi_thread_dispatch_apc_queue which calls
1790 the enqueued APCs. Defined a new struct ApcInfo that holds information
1791 about an enqueued APC.
1792 * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same
1793 as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue.
1794 These last two methods call the corresponding apc methods in
1795 thread-private using the provided thread handle.
1796 * threads.h: Added QueueUserAPC.
1797 * uglify.h: Added WapiApcProc (needed by QueueUserAPC).
1798 * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and
1799 WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support
1800 for APCs in those two methods and also in SleepEx.
1802 2004-05-17 Dick Porter <dick@ximian.com>
1804 * io.c (CopyFile): Speed up. Fixes bug 57859.
1806 2004-05-13 Dick Porter <dick@ximian.com>
1807 * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current
1808 thread doesn't own the mutex, rather than assert()ing.
1810 2004-05-11 Dick Porter <dick@ximian.com>
1812 * shared.c (_wapi_shm_attach): Cope when a previous daemon startup
1813 attempt failed, leaving shared files that look like a daemon is
1816 2004-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1819 (SetFileAttributes): don't the the exec bit if the corresponding read
1822 2004-05-10 Zoltan Varga <vargaz@freemail.hu>
1824 * io.c (FindFirstFile): Fix invalid free.
1826 2004-05-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1828 * io.c: translate from GFileError to errno codes and don't free
1829 variables right after calling mono_io_scandir, as we may overwrite
1832 2004-05-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1834 * io.c: g_dir_open return ENOENT for directories on which we don't have
1835 read/execute permission, while returning EPERM for anything below those.
1836 So, change ENOENT by EPERM if the directory exists.
1838 2004-05-07 Dick Porter <dick@ximian.com>
1840 * io.c (SetFileAttributes): Don't have failed chmod()s cause a
1841 "file not found" error. Fixes bug 54032.
1843 2004-05-07 Dick Porter <dick@ximian.com>
1845 * io.c (FindFirstFile): Comment out a windows-compatibility check
1846 that breaks when directories have metachars in their names.
1847 Workaround for bug 58116.
1849 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1851 * io.c: fixed for FindFirstFile for empty directories. Closes
1854 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1856 * processes.c: set the start time for the current process. Fixes bug
1859 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1861 * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
1862 * io.c: implemented scandir using glib functions.
1864 2004-05-04 Dick Porter <dick@ximian.com>
1866 * daemon.c (read_message): Return FALSE on error so the GSource
1867 callback itself can return FALSE. Cures the infinite loop poll()
1869 * shared.c: Fix some daemon startup race conditions.
1871 2004-04-29 Miguel de Icaza <miguel@ximian.com>
1873 * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k,
1874 use the stack, do not use dynamic memory.
1876 2004-04-29 Zoltan Varga <vargaz@freemail.hu>
1878 * io.c: Add scandir implementation for platforms which do not have
1881 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1883 * io.[ch]: implemented GetLogicalDriveStrings.
1885 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1888 * sockets.c: use the field name from configure when accessing sigval
1889 pointer field. Makes this work on the Mac.
1891 2004-04-28 Bernie Solomon <bernard@ugsolutions.com>
1893 * atomic.c: (InterlockedExchange) fix typo for
1896 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1899 * sockets.c: added check for sys/aio.h.
1901 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1903 * error.[ch]: added _wapi_get_win32_file_error...
1904 * io.c: ... which was _wapi_get_win32_error here.
1905 * sockets.c: rename the function calls here too.
1907 2004-04-28 Dick Porter <dick@ximian.com>
1909 * daemon-messages.c: Avoid a deadlock when a thread is killed while
1910 waiting for the daemon by using a recursive mutex. Helps bug 56699.
1912 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1914 * io.c: fixed leak in async_notifier().
1916 * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl
1919 * threads.c: removed old comment.
1921 2004-04-26 David Waite <mass@akuma.org>
1923 * daemon-messages.h:
1930 * wapi-private.h: remove comma from end of enumeration declarations
1931 * status.h: cast unsigned int types to int for enum assignment
1933 2004-04-26 David Waite <mass@akuma.org>
1936 * timefuncs.c: declare 64-bit constants as long long types (i.e.
1939 2004-04-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1941 * socket-wrappers.h: _wapi_socket == WSASocket now. Added
1942 WSA_FLAG_OVERLAPPED.
1944 * sockets.c: new unused parameters for _wapi_socket.
1946 2004-04-22 Miguel de Icaza <miguel@ximian.com>
1948 * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle
1949 the fact that MacOS X is a piece of junk (sem_init is *defined* in
1950 the libc, but they return `not implemented').
1952 2004-04-22 Dick Porter <dick@ximian.com>
1955 * handles-private.h: Reference the handle when it is locked, so
1956 that another thread can't blow it away while we're waiting for it
1957 to become signalled.
1968 * handles-private.h:
1971 * daemon-messages.c:
1972 * critical-sections.c:
1973 * atomic.c: Added pthreads cleanup handlers and error asserts
1976 * handles.c: Fixed the gcc "variable might be used uninitialised"
1977 warnings. They can't happen, but gcc doesn't know that
1978 g_assert()s don't return.
1980 Fixed the declaration of _wapi_handle_process_kill() so that it
1981 expects the correct type for the pid.
1983 * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that
1984 hasn't been used in ages and just made the code more complex.
1986 2004-04-17 Zoltan Varga <vargaz@freemail.hu>
1988 * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
1989 warnings. Fixes #57168.
1991 2004-04-16 Dick Porter <dick@ximian.com>
1993 * threads.c (Sleep): Using div(3) with a negative (when signed)
1994 numerator causes the quotient to be 0 and the remainder to be the
1995 numerator. This feeds a small negative value to nanosleep(3),
1996 which will return immediately and cause a busy wait. Fixes bug
1999 2004-04-15 Dick Porter <dick@ximian.com>
2002 * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3)
2003 and fnmatch(3) instead of glob(3). glob() can't cope with being
2004 given filenames containing metachars. This fixes bug 40557.
2006 2004-04-14 Bernie Solomon <bernard@ugsolutions.com>
2008 * security.c: #warning is a GCC-ism
2010 2004-04-13 Sebastien Pouliot <sebastien@ximian.com>
2012 * security.c: Removed GetUserName as glib g_get_user_name does a
2013 better (portability) job. Added ImpersonateLoggedOnUser and
2016 2004-04-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2018 * mono-mutex.h: move pthread_mutex_timedlock declaration to...
2019 * mono-mutex.c: ...here. It was causing a warning that prevented
2020 libgdiplus compilation.
2022 2004-04-04 Miguel de Icaza <miguel@ximian.com>
2024 * security.c (GetUserName): Make it work on MacOS X
2026 2004-04-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2028 * security.c: use getpwuid_r if available. This one is thread-safe.
2030 2004-04-02 Sebastien Pouliot <sebastien@ximian.com>
2032 * Makefile.am: Added security.c|h.
2033 * security.c: New file for security related functions. Added function
2034 GetUserName to fix #56144.
2035 * security.h: New. Header file for security.c
2036 * wapi.h: Added include for security.h
2038 2004-03-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2040 * daemon-messages.h: added kill structs.
2042 * daemon.c: implemented process_process_kill.
2043 * handles-private.h: define process_process_kill.
2044 * handles.c: implemented _wapi_handle_process_kill.
2045 * processes.[ch]: implemented TerminateProcess.
2047 2004-03-25 Bernie Solomon <bernard@ugsolutions.com>
2049 * daemon.c (rem_fd): On solaris you seem to get an
2050 error even after removing the input source so don't
2051 try and rem_fd it twice.
2053 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
2055 * daemon.c: in process_post_mortem, If the child terminated due to the
2056 receipt of a signal, the exit status must be based on WTERMSIG, since
2057 WEXITSTATUS returns 0 in this case.
2059 2004-03-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2061 * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.
2063 2004-03-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2065 * daemon.c: only call getdtablesize () once.
2066 * processes.c: wait 500 ms to check if execve failed and throw the same
2067 exception as MS on failure. Fixes bug #32809.
2069 2004-03-17 Bernie Solomon <bernard@ugsolutions.com>
2071 * io.c (async_notifier): use "union sigval" rather
2072 than sigval_t as Solaris doesn't have sigval_t
2073 (which isn't in IEEE 1003.1 either).
2075 2004-03-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2077 * io.c: added debug stuff and removed a few redundant lines in
2080 2004-03-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2082 * io-private.h: added new fields for file structure. Declare
2083 _wapi_io_add_callback.
2085 * io.c: added _wapi_get_win32_error, support aio_read/write in
2086 file_read/write. Implemented _wapi_io_add_callback, which is where
2089 * io.h: added new fields for WapiOverlapped and typedef for the
2092 * processes.c: fixed off-by-one bug when handling environment variables
2095 * threads.[ch]: implemented BindIoCompletionCallback.
2097 * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE.
2099 2004-03-14 Zoltan Varga <vargaz@freemail.hu>
2101 * socket-wrappers.h: Remove extra semicolon.
2103 2004-03-03 Dave Camp <dave@ximian.com>
2105 * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
2106 Use a new main context.
2108 2004-03-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2111 (GetFileAttributes): set the error depending on errno instead of
2112 setting ERROR_FILE_NOT_FOUND always. See bug #55160.
2114 2004-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2117 (CopyFile): free the buffer on error.
2119 (WSAIoctl): free the buffer on error.
2121 2004-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2123 * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT.
2125 * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW
2126 using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style.
2128 2004-01-27 Bernie Solomon <bernard@ugsolutions.com>
2130 * shared.c (_wapi_shm_file): add hostname
2131 to shared data file names to handle NFS mounted
2134 Mon Jan 26 16:15:03 CET 2004 Paolo Molaro <lupus@ximian.com>
2136 * sockets.h: remove obsolete soklen_t typedef.
2138 Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>
2140 * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket
2141 wrappers to its own non-installed header file.
2143 2004-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2146 (FindFirstFile): unlock the handle if FindNextFile fails.
2147 (FindNextFile): g_free a couple of pointers before retrying.
2150 (WaitForMultipleObjects): if only one handle provided, use
2151 WaitForSingleObject.
2153 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2155 * handles-private.h: (_wapi_handle_type) check
2156 for segment in range before using it
2158 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2160 * thread-private.h: _wapi_thread_ops is now const
2163 Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>
2165 * threads.c, timed-thread.c, timed-thread.h: use mach
2166 semaphores on Darwin (MacOSX) since the posix ones
2167 are mostly broken there (threads are not created suspended
2168 and they can start executing before they are fully initialized
2169 like in tests/thread-static.cs).
2171 Mon Dec 22 17:18:45 CET 2003 Paolo Molaro <lupus@ximian.com>
2173 * atomic.h: ppc fixes.
2175 2003-12-19 Bernie Solomon <bernard@ugsolutions.com>
2177 * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
2180 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2182 * shared.c: (_wapi_shm_open) make scratch file
2183 not have to immediately regrow to avoid remaps
2184 (HPUX can't cope with these).
2185 (_wapi_shm_attach) use actual size of file
2186 to set scratch data_len for the creating process.
2188 * handles.c: (_wapi_handle_new_internal) make
2189 sure mutex & cond var are initialized even for
2190 non process shared ones.
2191 (_wapi_handle_unref) always call destroy
2192 routines on mutex & cond var
2194 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2196 * daemon.c: change channel data structure so
2197 input sources are removed from glib event loop
2198 properly. xsp works better on Solaris and
2201 2003-12-12 Bernie Solomon <bernard@ugsolutions.com>
2203 * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
2204 definition with file & line number for non-GCC
2207 2003-12-08 Bernie Solomon <bernard@ugsolutions.com>
2209 * Makefile.am: make sure hppa_atomic.s is in distribution
2211 2003-12-01 Dick Porter <dick@ximian.com>
2214 * mutexes.c (CreateMutex):
2215 * mutex-private.h (struct _WapiHandle_mutex):
2216 * handles.c: Look up certain handle types by name, in a shared
2217 namespace. Currently only mutex handles have this implemented.
2220 * semaphores.c (CreateSemaphore):
2221 * events.c (CreateEvent): Fix signature
2223 2003-11-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2225 * io.c: don't call g_free before testing errno as it may modify it.
2226 If the path exists, return an error if it's not a directory. Fixes
2229 2003-11-20 Dick Porter <dick@ximian.com>
2231 * io.c: Missed a little-endian UTF16 conversion. Patch from
2232 Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.
2234 2003-10-29 Dick Porter <dick@ximian.com>
2236 * io.c (MoveFile): If the move crosses filesystems, try and fall
2237 back to copy and delete. Patch from Jörg Rosenkranz
2238 (JoergR@voelcker.com), fixes bug 50298.
2240 2003-10-28 Dick Porter <dick@ximian.com>
2242 * io.c: Use the new encoding conversion to cope with non-utf8
2243 locales in filenames.
2245 * processes.c: Ditto for process arguments.
2247 Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro <lupus@ximian.com>
2249 * atomic.h: some ppc inline asm fixes (incorrect use of labels,
2250 incorrect register constraints, incorrect clobber lists).
2252 2003-10-13 Bernie Solomon <bernard@ugsolutions.com>
2254 * Makefile.am hppa_atomic.s: add HP 64bit
2255 implementation of atomic ops
2257 2003-10-13 Zoltan Varga <vargaz@freemail.hu>
2259 * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
2260 a conditional for platforms that don't have it.
2262 2003-10-09 Bernie Solomon <bernard@ugsolutions.com>
2264 * threads.c: (CreateThread) use stacksize argument
2265 if non-zero - change default for 64 bits to 4Mb
2267 2003-09-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2269 * sockets.c: set last error when socket creation fails. This shed some
2270 light on bug #49015.
2272 2003-09-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2274 * processes.c: fixed bug #48973: we only change \ by / for the argument
2275 to be used as command.
2276 When getting the program name from the args, don't let the space between
2279 2003-09-24 Bernie Solomon <bernard@ugsolutions.com>
2281 * atomic.h atomic.c: fix sparc so lock is
2282 global, increment does so and it compiles under Sun compiler.
2284 2003-09-22 Bernie Solomon <bernard@ugsolutions.com>
2286 * handles.c: include <string.h> directly as may
2287 not be nested in <sys/un.h> like Linux
2289 2003-09-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2292 (DeleteFile): call SetLastError on failure. Fix by
2293 richard.torkar@htu.se (Richard Torkar). Closes bug #48222.
2295 2003-09-15 Lluis Sanchez Gual <lluis@ximian.com>
2297 * daemon.c: In compare_process(), discard handles already signalled.
2299 2003-09-02 Dick Porter <dick@ximian.com>
2301 * io.c: Work around glib brain-dead assumptions about utf8-encoded
2302 filenames. Fixes bug 30781.
2304 2003-08-28 Dick Porter <dick@ximian.com>
2306 * critical-sections.c: Patch from Bernie Solomon
2307 <bernard@ugsolutions.com> to emit a warning if locking a critical
2310 2003-07-23 Dick Porter <dick@ximian.com>
2313 * daemon.c (maybe_exit): Avoid the race condition when the daemon is
2314 closing but another client comes along when the shared data is still
2315 visible. Should fix bugs 33671 and 35213.
2317 2003-07-23 Dick Porter <dick@ximian.com>
2319 * handles.c: Initialise handle mutex and cond. Fix by
2320 Bernie Solomon <bernard@ugsolutions.com>
2322 2003-07-15 Dick Porter <dick@ximian.com>
2324 * timed-thread.c (timed_thread_start_routine): Fix virtual memory
2325 leak when threads quit. Fixes bug 44067.
2327 Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro <lupus@ximian.com>
2329 * io.c: never add write permission for group or others in
2330 SetFileAttributes ().
2332 2003-06-17 Dick Porter <dick@ximian.com>
2334 * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
2335 ignore the unsupported ones ("fixes" bug 44977).
2337 2003-06-17 Lluis Sanchez Gual <lluis@ximian.com>
2339 * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for
2340 high ms values (there was an overflow).
2342 2003-06-17 Zoltan Varga <vargaz@freemail.hu>
2344 * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.
2346 2003-06-11 Dick Porter <dick@ximian.com>
2348 * shared.c: Fix shared directory creation. Patch from
2349 Pablo Baena <pbaena@uol.com.ar>
2351 2003-06-10 Dick Porter <dick@ximian.com>
2353 * atomic.c: Delete the useless compile warning
2355 2003-06-09 Dick Porter <dick@ximian.com>
2357 * daemon.c: Lookup env as a string array. Fixes bug 44289. Also
2358 make setting the process handle value in the environment actually
2361 * processes.c: Pretty up the process name, if it happens to be
2362 "mono" such as when another mono process forks "mono foo.exe"
2364 2003-06-05 Dick Porter <dick@ximian.com>
2366 * processes.c (process_set_current): Don't do an expensive handle
2367 search at application startup, check the environment to see if the
2368 process handle has already been created.
2370 * io.c: Don't do an expensive handle search when creating stdin,
2371 stdout and stderr handles, just create them all the first time one
2378 * handles-private.h:
2379 * daemon-messages.h:
2381 * daemon.c: Support for "unlimited" number of handles and scratch
2384 Speed up application startup by passing process handle in the
2385 environment, rather than let the app scan all handles (which gets
2386 really slow when there are more than a few thousand to check.)
2388 Initialise some structs passed to syscalls, noticed by valgrind.
2391 2003-05-20 Dick Porter <dick@ximian.com>
2393 * io.c (FindFirstFile): Include . files in the glob. Fixes bug
2396 2003-05-19 Dick Porter <dick@ximian.com>
2398 * threads.c: Set the new thread's stack size to 2M. Fix needed
2399 for BSD, reported by Martin Dvorak <md@9ll.cz>
2401 2003-05-16 Dick Porter <dick@ximian.com>
2404 * io.c: Implement GetTempPath()
2406 2003-05-16 Dick Porter <dick@ximian.com>
2408 * processes.c (CreateProcess): Set some error codes
2410 2003-05-12 Dick Porter <dick@ximian.com>
2412 * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
2413 Patch from Martin Dvorak <mdvorak@ninell.cz>.
2415 2003-05-10 Dick Porter <dick@ximian.com>
2417 * io.c (CopyFile): Copy file mode as well as file data. Based on
2418 suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
2421 2003-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2423 * handles.c: don't call GC_gcollect when creating new handles.
2425 2003-05-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2427 * handles.c: added some debugging code. Call GC_gcollect
2428 before creating a new handle. It makes Lupus' test run smoother and
2429 faster (from 62 to 83 request per second). Notice that calling
2430 GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does
2431 not improve nor degrade the performance, so i don't do it.
2433 2003-05-02 Dick Porter <dick@ximian.com>
2435 * sockets.c: Rearrange closesocket() and socket_close_private(),
2436 and remember to unref the handle, so we don't leak socket handles.
2437 Fix from Pelle Johnsen <pelle.johnsen@mail.dk>
2439 2003-04-11 Dick Porter <dick@ximian.com>
2441 * atomic.h: ARM atomic operations by Malte Hildingson
2442 <tds00mahi@tellus.thn.htu.se>
2444 Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>
2446 * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.
2448 2003-04-03 Martin Baulig <martin@ximian.com>
2450 The following change is conditional to `WITH_INCLUDED_LIBGC'
2451 which is not yet enabled by default.
2453 * threads.c (SuspendThread, ResumeThread): Fully implemented this.
2454 (gc_init): New static function; install a signal handler for
2455 SIGPWR which is used to suspend threads. [FIXME: it SIGPWR
2456 doesn't exist on all Unix systems, we need to find another
2458 (mono_wapi_push_thread_stack): New public function. Tells the
2459 garbage collector about the current stack pointer of a suspended
2462 2003-04-03 Martin Baulig <martin@ximian.com>
2464 * timed-thread.h (TimedThread): Added `suspended_sem',
2465 `suspend_count' and `stack_ptr'.
2467 2003-03-28 Dick Porter <dick@ximian.com>
2469 * atomic.h: PPC support gratiously donated to the public domain
2470 by John Duncan <jddst19@mac.com>
2472 2003-03-20 Dick Porter <dick@ximian.com>
2474 * sockets.c (_wapi_connect): If connect() fails with EACCES, try
2475 setting SO_BROADCAST and connecting again. Fixes bug 39178.
2477 2003-03-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2479 * processes.c: included Jerome Laban's patch and call SetLastError when
2480 the executable is not found.
2482 2003-03-03 Dick Porter <dick@ximian.com>
2484 * io.c (CreateFile): Try opening directories readonly, so that
2485 timestamps can be adjusted. Patch by Elan Feingold
2486 <efeingold@mn.rr.com>.
2488 2003-02-25 Dick Porter <dick@ximian.com>
2490 * shared.c (_wapi_shm_attach): Return a failure code on system
2491 call errors, rather than exiting.
2493 2003-02-21 Dick Porter <dick@ximian.com>
2495 * processes.c (GetCurrentProcessId): Use the current process
2496 handle to return the process ID, as getpid() is unreliable
2497 (linuxthreads gives each thread a different pid). Fixes bug
2500 2003-02-21 Dick Porter <dick@ximian.com>
2502 * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug
2505 2003-02-11 Dick Porter <dick@ximian.com>
2508 * timefuncs.c: Added GetTickCount()
2510 2003-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2512 * error.c: added WSA_EHOSTUNREACH mapping.
2514 2003-01-26 Miguel de Icaza <miguel@ximian.com>
2516 * io.c (SetFileAttributes): This routine is not currently
2517 implemented for the general case, but I added a special case to
2518 set the executable bit on Linux.
2520 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
2522 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
2524 2003-01-08 Dick Porter <dick@ximian.com>
2526 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
2528 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
2530 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2531 Check for an implementation which says it supports
2532 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
2533 defines the symbol. Defined but with a value of -1 still
2534 means that it is unsupported.
2536 2002-12-08 Martin Baulig <martin@ximian.com>
2538 * handles.c (_wapi_handle_new): Create new non-shared handles with
2539 an initial refcount of 1, not 0.
2541 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
2543 * threads.c (TlsGetValue): removed unnecessary mutex
2545 2002-11-20 Dick Porter <dick@ximian.com>
2547 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
2548 need to store their data structure too.
2550 * threads.c: Make sure the threading data is initialised wherever
2553 2002-11-15 Dick Porter <dick@ximian.com>
2555 * timed-thread.c: Removed unneeded parameters in
2556 _wapi_timed_thread_attach().
2558 * threads.c: Renamed AttachThread() to make it not look like
2559 external API. Removed unneeded parameters.
2561 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2563 * error.[ch]: added errno_to_WSA (). It displays a warning and return
2564 WSASYSCALLFAILURE if there is no error mapping for the given errno,
2566 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
2568 2002-10-31 Dick Porter <dick@ximian.com>
2571 * io.c: Define and use INVALID_FILE_ATTRIBUTES
2573 2002-10-07 Dick Porter <dick@ximian.com>
2576 * daemon.c: Use a more accurate time source for process start and
2579 2002-10-03 Dick Porter <dick@ximian.com>
2583 * threads.c: Fixes for freebsd. Make sure that mutex and condition
2584 creation and deletion happen in the process that owns them, when
2585 POSIX shared thread objects aren't supported. This breaks on
2586 freebsd, as pthread_t is a pointer to data.
2588 2002-10-02 Dick Porter <dick@ximian.com>
2590 * shared.c: Use mmap() instead of sysv shm for the shared data.
2592 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
2596 * daemon.c: mmap()ed regions survive fork, so just pass the
2597 pointer to _wapi_daemon_main instead of mapping it again.
2599 2002-10-01 Dick Porter <dick@ximian.com>
2601 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
2602 Unfortunately libgc uses the same thread suspend technique that I
2603 want to, and the two don't mix: libgc will deadlock when it tries
2604 to stop the world if a thread has already been suspended by
2605 someone else. Just do the simple suspended create rather than the
2606 general purpose thread suspension for now.
2608 * threads.c: Pass create flags to the timed_thread create call, to
2609 implement suspended thread creation. ResumeThread() partially
2610 implemented, to cope with the case where a newly created but
2611 suspended thread is launched.
2613 2002-09-30 Dick Porter <dick@ximian.com>
2615 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
2618 2002-09-27 Dick Porter <dick@ximian.com>
2620 * semaphores.c: Only include semaphore.h if it's present. Patch
2621 for BSD from jmmv@hispabsd.org (Julio Merino).
2623 2002-09-27 Dick Porter <dick@ximian.com>
2625 * processes.c: Pass environment and working directory to the
2626 daemon when forking. Don't let argv[0] be duplicated when looking
2627 for the program name. Implement EnumProcessModules (simple
2628 version for now, lsof-style later if needed), GetModuleBaseName,
2629 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
2630 aren't available on Linux).
2632 * process-private.h: Store the process name, and the working set
2636 * handles-private.h: New functions to store and retrieve an array
2637 of strings in the scratch space
2639 * daemon.c: Don't miss deleting some handles when a client exits
2640 (we used to rely on the client doing the final cleanup, but
2641 obviously if the client is no longer there the daemon has to do
2644 Process forking now sets the environment and the working
2647 * io.c: Don't confuse fd 0 with an unassigned handle struct
2649 * atomic.h: Add a google cache alternative to the msdn URL
2651 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2654 (_wapi_recvfrom): added ECONNRESET to the switch.
2656 2002-09-24 Mark Crichton <crichton@gimp.org>
2658 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
2661 2002-09-19 Mark Crichton <crichton@gimp.org>
2663 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
2664 dont have Linux's abstract filesystem for sockets.
2666 2002-09-19 Mark Crichton <crichton@gimp.org>
2668 * atomic.h: Added SPARC atomic asm code.
2669 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2670 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
2671 Solaris 9, however, the code paths don't seem to work. More testing
2672 on the shared case is *really* needed.
2674 2002-09-03 Dick Porter <dick@ximian.com>
2677 * threads.c: Removed PosixKillThread(), because it's not in the
2680 2002-08-20 Dick Porter <dick@ximian.com>
2682 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
2683 multiples of 4 bytes, to keep header structures aligned. Needed
2684 for sparc, at least. (Patch from crichton@gimp.org)
2686 * handles.c: Removed 'disable_shm' variable (we've defaulted to
2687 building with shm enabled for months now)
2689 2002-08-19 Dick Porter <dick@ximian.com>
2691 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
2692 for legacy NeXT-based systems.
2694 2002-08-12 Dick Porter <dick@ximian.com>
2696 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
2697 from Joseph Wenninger <kde@jowenn.at>)
2699 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
2701 * threads.c: use fast spinlocks by default
2703 2002-08-02 Dick Porter <dick@ximian.com>
2705 * io.c (GetStdHandle): Add a handle reference when returning a
2706 duplicate console handle. This fixes the unref_handle errors in
2709 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
2711 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
2714 2002-08-01 Dick Porter <dick@ximian.com>
2716 * threads.c: Use atomic spinlocks in TLS functions
2719 * Makefile.am: Added mono-spinlock.h
2721 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
2723 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
2724 these are needed for sendmsg() and also for struct msghdr (at
2725 least on Solaris). Solaris still won't build because struct msghdr
2726 doesn't have msg_flags, msg_control, or msg_controllen members.
2727 (CMSG_SPACE): Define for systems that don't have it.
2730 2002-07-20 Dick Porter <dick@ximian.com>
2736 * handles.c: Implemented pipe handles
2739 * daemon.c: Fixed bug in handle closing.
2742 * daemon.c: Forked processes now close all open file descriptors.
2744 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
2746 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
2749 2002-07-19 Martin Baulig <martin@gnome.org>
2751 * threads.c (ExitThread): Call exit() if no threads has been
2754 2002-07-17 Dick Porter <dick@ximian.com>
2756 * daemon-messages.c: Freebsd fixes from Andreas Kohn
2757 <andreas.kohn@gmx.net>
2759 2002-07-15 Dick Porter <dick@ximian.com>
2761 * io.c: Removed bogus console_flush() method, that was just cut
2762 and pasted from file_flush when I separated the two handle types.
2764 2002-07-12 Dick Porter <dick@ximian.com>
2766 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
2767 flags. Fixes bug 27633.
2769 2002-07-12 Dick Porter <dick@ximian.com>
2773 * daemon.c: Use size of sockaddr_un.sun_path from config.h
2775 2002-07-12 Dick Porter <dick@ximian.com>
2777 * processes.c (CreateProcess): Send stdin, stdout and stderr
2778 handles if the startup info doesnt specify new ones
2780 * io.c (GetStdHandle): Return the same handle when the same
2781 standard handle is requested
2783 * handles.c: Pass file descriptors when forking
2785 * daemon.c: Use supplied file descriptors when forking a new
2788 * daemon-messages.h:
2789 * daemon-messages.c: Pass stdin, stdout and stderr file
2790 descriptors to the daemon (used when forking)
2792 2002-07-11 Miguel de Icaza <miguel@ximian.com>
2794 * daemon.c (_wapi_daemon_main): Use sizeof
2795 (main_socket_address.sun_path) instead of hardcoded 108 value.
2797 * handles.c (shared_init): Use sizeof
2798 (shared_socket_address.sun_path) instead of hardcoded 108 value.
2800 2002-07-10 Dennis Haney <davh@davh.dk>
2804 * daemon.c: Lots of documentation, some added error checking, and
2805 code readability improvements.
2807 * daemon-messages.h: Add the Error request type to improve error
2810 * daemon-messages.c: Do a bit more error checking on send() and
2811 recv(), and log errors with a higher severity level.
2813 2002-07-04 Dick Porter <dick@ximian.com>
2815 * daemon.c (process_process_fork): Fix argument handling, due to
2816 buggy understanding of g_strsplit() behaviour.
2818 2002-07-03 Dick Porter <dick@ximian.com>
2821 * threads.c: Implement OpenThread(). Define access-control values
2827 * Makefile.am: Added access.h, to hold shared access-control
2830 2002-07-02 Dick Porter <dick@ximian.com>
2832 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
2834 2002-07-02 Dick Porter <dick@ximian.com>
2836 * handles.c (shared_init): Make a second attempt to contact the
2837 daemon if the shared memory attach succeeds, but the connect()
2838 fails. (This copes with the daemon crashing without cleaning up
2844 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
2845 the daemon, it's now built into the library.
2847 2002-06-25 Dick Porter <dick@ximian.com>
2850 * handles-private.h:
2851 * daemon-messages.h:
2852 * daemon.c: Process forking and handle data management
2855 * process-private.h:
2856 * processes.c: Process forking and other support functions
2858 2002-06-25 Dick Porter <dick@ximian.com>
2860 * versioninfo.h: PE resource decoding
2862 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
2863 to be told the string length
2865 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
2866 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
2869 2002-06-12 Dick Porter <dick@ximian.com>
2872 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
2873 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
2874 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
2876 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
2878 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
2879 when writing to a closed socket.
2881 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
2883 * mono-mutex.c (mono_once): New convenience function for my
2888 * critical-sections.c:
2896 * atomic.c: Use mono_once() rather than pthread_once().
2898 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
2900 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
2901 if multiple threads all try to call _wapi_handle_new() before the
2902 shared data has been initialized, it is possible that we could get
2903 into a condition where shared_init() is being executed and later
2904 threads will pass by pthread_once() due to the fact that it has
2905 already been called and so therefor will attempt to use the shared
2906 data before it has been completely initialized. If we instead use
2907 a standard mutex locking mechanism around shared_init(), we can
2908 avoid the situation entirely. By wrapping the mutex locking in a
2909 check to see if we've already initialized the data, we can even
2910 avoid wasting resources by having to lock/unlock the mutex in any
2911 later calls (the only time we'd have to worry about
2912 locking/unlocking is the initial race to call shared_init() at
2915 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
2917 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
2919 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
2921 * daemon.c, handles.c: rename "sun" local var since it's apparently
2922 a #define on Solaris.
2924 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
2926 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
2929 2002-05-15 Dick Porter <dick@ximian.com>
2931 * wait.c: Fix a deadlock in WaitForMultipleObjects
2933 2002-05-14 Dick Porter <dick@ximian.com>
2935 * io.c: Fix a cut&paste error, found by
2936 Jaroslaw Kowalski <jarek@atm.com.pl>
2938 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
2942 2002-05-09 Dick Porter <dick@ximian.com>
2948 * handles-private.h:
2950 * Makefile.am: Remove now-unused file wait-private.h
2952 2002-05-08 Dick Porter <dick@ximian.com>
2954 * shared.c: Better error messages, and report when daemon
2955 connection fails rather than blocking forever. Do some more
2956 shared memory sanity checking.
2958 * handles.c: Better error messages when connecting to shared
2959 memory and the handle daemon. Fall back to non-shared handles if
2960 an error occurs. Set the default back to 'shared handles'. Fix a
2961 crashing bug in scratch space allocation that mangled the block
2964 2002-05-07 Miguel de Icaza <miguel@ximian.com>
2966 * handles.c (shared_init): Disable SHM for now, people have too
2967 many problems with this, and the diagnostics are not helping.
2969 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
2971 * io.c: CreateFile sets win32 last error.
2973 2002-05-05 Dick Porter <dick@ximian.com>
2976 * handles-private.h:
2982 * process-private.h:
2984 * semaphore-private.h:
2988 * event-private.h: Simplify the WapiHandleOps struct: take out all
2989 the file-specific entries, leaving just the items that operate on
2990 handles themselves. Split the close operation into shared and
2991 private parts: shared close is called by the daemon.
2993 * handles.c: As above, but also pass handle allocation, ref and
2994 unref operations to the daemon. Populate the handle_ops array at
2995 compile time, because the daemon needs to call ops on handles too.
2996 Don't bother to track open handle counts any more, the daemon does
3000 * thread-private.h: As above, but also make the thread data
3003 * shared.c: Fork a handle daemon if the calling process created
3004 the shared memory segment.
3007 * daemon-messages.c:
3008 * daemon-messages.h:
3009 * Makefile.am: Build a daemon to manage handle allocation and
3010 destruction without needing to lock the shared memory
3012 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
3014 * atomic.c: Changed to use a normal mutex rather than a spinlock
3015 since a lot of platforms seem to not have them :\
3017 2002-04-30 Dick Porter <dick@ximian.com>
3019 * Completely rewrote the handle waiting code: removed the helper
3020 thread and its attendant complexity. All handle waiting is now
3021 abstracted into the WaitForSingleObject() and
3022 WaitForMultipleObjects() functions.
3024 * Implemented inter-process sharing of handles using sysv shared
3025 memory. This makes handles even more opaque, with a handle now
3026 just an index into an array.
3028 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
3030 * io.c: unitialized pointer in GetCurrentDirectory.
3032 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
3034 * threads.c: destroy the mutex at thread destruction
3035 (if/when thread destruction code will be actually called).
3036 When protecting a tls data pointer from the gc, use also the
3037 thread id in the key.
3039 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
3041 * timed-thread.c: avoid race condition when setting the thread to
3044 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3046 * jit.h: to more #include lines to avoid breaking compilation
3047 under windows when upgrading mingw and w32api to version
3050 2002-04-16 Dick Porter <dick@ximian.com>
3052 * atomic.h: Explanatory comment about lack of 80386 support
3054 2002-04-15 Dick Porter <dick@ximian.com>
3056 * atomic.h: use xaddl for InterlockedIncrement() and
3057 InterlockedDecrement(). Use cmpxchgl in a loop for
3058 InterlockedExchange() and InterlockedExchangePointer().
3060 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
3062 * unicode.c: fix unicode_len() to not access uninitialized memory
3063 (and updated to conform to mono code style).
3065 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
3067 * io.c: EEXISTS is ignored for directory creation.
3068 * mono-mutex.h: remove silly "pragma }" that emacs users insert
3069 because they use a broken editor:-)
3071 2002-03-28 Dick Porter <dick@ximian.com>
3077 * handles.c: Warning cleanups
3079 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
3081 * unicode.h, unicode.c: changed to gunichar2
3082 * io.h, io.c: changed strings to gunichar2*, added
3083 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
3084 some fixes to FindFirstFile() and friends.
3086 2002-03-26 Dick Porter <dick@ximian.com>
3088 * types.h: Implement the large integer struct
3091 * timefuncs.c: Dummy functions that don't yet implement
3092 QueryPerformanceCounter() and QueryPerformanceFrequency()
3095 * threads.c: Implement SleepEx()
3098 * system.c: Beginnings of GetSystemInfo()
3100 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
3104 * context.c: Dummy function that doesnt yet implement
3108 * atomic.c: Interlocked functions
3110 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
3112 * threads.c: use a gc-safe hash table to store tls pointers.
3114 2002-03-22 Dick Porter <dick@ximian.com>
3116 * threads.c: Fix a race condition where a thread can start and
3117 exit before the handle has been properly initialised (no reason
3118 why the handle couldn't be initialised beforehand, so do so)
3120 Fix a ms to ns conversion magnitude thinko.
3122 2002-03-21 Dick Porter <dick@ximian.com>
3124 * semaphores.c: Fix a problem when waiting for one or more
3125 semaphores, and another semaphore is Released (all waiting
3126 semaphores assumed they were signalled)
3128 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
3130 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
3131 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
3133 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
3135 * threads.c (Sleep): bug fix: 1ms == 1000000ns
3137 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
3139 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
3140 threads.c, io.c: added flush method to handles.
3142 * io.c: FlushFileBuffers() and FindFirstFile() functions.
3144 Thu Mar 7 17:21:52 CET 2002 Paolo Molaro <lupus@ximian.com>
3146 * threads.c, timed-thread.c, wait.c: Boehm-GC anable.
3148 2002-02-20 Dick Porter <dick@ximian.com>
3150 * io-layer.h: Always build without cygwin support on windows
3152 Mon Feb 18 15:50:59 CET 2002 Paolo Molaro <lupus@ximian.com>
3154 * sockets.c: #undef DEBUG.
3156 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
3158 * io-layer.h: conditionally include sys/filio.h and sys/sockio.h
3159 for FIONBIO, FIONREAD, and SIOCATMARK.
3161 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
3163 * sockets.c: conditionally include sys/filio.h and sys/sockio.h
3164 for FIONBIO, FIONREAD, and SIOCATMARK.
3166 2002-02-13 Dick Porter <dick@ximian.com>
3168 * sockets.c: Implement shutdown and select
3170 2002-02-13 Jeffrey Stedfast <fejj@ximian.com>
3172 * mono-mutex.[c,h]: New source files that thinly wrap all pthread
3173 functions that take pthread_mutex_t and/or pthread_mutexattr_t
3174 arguments for the sake of portability. Implements recursive
