26 * processes.c (load_modules): Applied patch from Thomas Philpot
27 (tom.philpot@logos.com). Fixes #533893.
29 2009-09-15 Jeffrey Stedfast <fejj@novell.com>
31 * io.c (CreateFile): In the directory fallback case, use
32 _wapi_open() again so that IOMAP magic happens.
33 (CopyFile): Need to consistently use _wapi_open() here too.
34 (ReplaceFile): Use _wapi_open() here too and get rid of the
35 fallback code that tried re-opening the file w/o O_TRUNC since
36 there's no reason to do that.
38 2009-09-05 Zoltan Varga <vargaz@gmail.com>
40 * handles.c (_wapi_handle_real_new): Call _wapi_process_reap () when running
41 out of shared handes. Fixes #536776.
43 * processes.c (CreateProcess): Return false and set the error to
44 ERROR_OUTOFMEMORY when a process handle cannot be created.
45 (ShellExecuteEx): Propagate an ERROR_OUTOFMEMORY error code. Fixes part of
48 2009-09-01 Zoltan Varga <vargaz@gmail.com>
50 * processes.c (EnumProcessModules): Applied patch from Romain Tartière
51 (romain@blogreen.org). Fix this on freebsd/OSX. Fixes #533893.
53 2009-08-18 Christian Hergert <chris@dronelabs.com>
55 * wthreads.c: Roll back change for thread-id as it "embraces
56 and extends" the api by passing word-size for thread id on
59 2009-08-18 Christian Hergert <chris@dronelabs.com>
63 * wthreads.c: Be explicit when we are changing word sizes.
65 2009-08-18 Christian Hergert <chris@dronelabs.com>
67 * processes.c: Fix method declaration warnings.
68 * sockets.c: getsockopt() wants socklen_t for size.
70 2009-08-04 Miguel de Icaza <miguel@novell.com>
72 * posix.c (_wapi_stdhandle_create): Split this into a new file to
73 more easily support non-Posix platforms.
75 2009-07-20 Geoff Norton <gnorton@novell.com>
77 * thread-private.h: Use the new mono-semaphore.h.
79 2009-06-25 Gonzalo Paniagua Javier <gonzalo@novell.com>
81 * sockets.c: add the error number to the message so we can figure out
84 2009-06-25 Gonzalo Paniagua Javier <gonzalo@novell.com>
86 * wait.c: add missing 'break'.
88 2009-06-20 Zoltan Varga <vargaz@gmail.com>
90 * atomic.h: Fix ilp32 support on ppc.
92 2009-05-28 Mark Probst <mark.probst@gmail.com>
94 * collection.c (_wapi_collection_init): If pthread_create() fails,
95 try again with larger and then with no stack size set. Fixes
98 2009-05-26 Zoltan Varga <vargaz@gmail.com>
100 * shared.c (_wapi_shm_file): Avoid creating a .wapi directory here, create
101 it in _wapi_shm_file_open (), since platforms using posix shm don't need it.
103 2009-05-22 Miguel de Icaza <miguel@novell.com>
105 * wapi_glob.c: Do not need sys/param.h anymore, we now use the
106 POSIX PATH_MAX instead of BSD's MAXPATHLEN
108 * handles.c: Do not pull a reference to sockets if they are
111 * sockets.c: Allow for ports to define their own ioctlsocket.
113 * wthreads.c: Remove obsolete code that I recently introudced (the
114 hook for mono_register_thread_attr.
116 2009-05-22 Miguel de Icaza <miguel@novell.com>
118 * versioninfo.c: One missing signature, fixed.
120 2009-05-21 Miguel de Icaza <miguel@novell.com>
122 * daemon.c: Remove more DEBUG ifdef mess.
124 * shared.c (_wapi_shm_attach): Implemention for DISABLE_SHARED_HANDLES
126 2009-05-20 Miguel de Icaza <miguel@novell.com>
128 * sockets.c (ioctlsocket): Move support for MacOS semantics to the
129 ioctlsocket from the ifdef that was previously on metadata/
131 * wapi_glob.c (_wapi_glob): Use PATH_MAX from limits.h instead of
132 the BSD name from sys/param.h (MAXPATHLEN)
134 Do not include pwd.h as it is not used.
136 * thread-private.h: Use indent ifdef style for clarity
138 * sockets-wrappers.h: sys/socket.h conditional
140 * daemon-messages.h: sys/uio.h conditional.
142 * sockets.c: sys/ioctl.h conditional
144 * wthreads.c: work around for platforms with no thread fetching
147 * versioninfo.c: Use the portable mono_map_ interface instead of
148 using mmap directly and change the style to the Mono style.
150 Remove more DEBUG/ifdefs combos
152 * shared.c: Split the code to make DISABLE_SHARED remove all the
153 code that does not use the shared handles. Before it merely
154 removed some of it, with this we avoid hacks on platforms that can
157 Split the code to reduce the amount of ifdefs.
159 Remove #ifdef DEBUG from the source and use a macro instead.
161 2009-05-20 Miguel de Icaza <miguel@novell.com>
163 * locking.c: Split locking code into a separate file.
165 2009-05-18 Miguel de Icaza <miguel@novell.com>
167 * daemon.c: Move the compile check of MONO_SIZEOF_SUNPATH to the
170 * Rename `threads.c' to `wthreads.c' as broken build systems are
171 not able to cope with two files with the same name across multiple
174 2009-05-15 Geoff Norton <gnorton@novell.com>
176 * handles.c: Don't start the collection thread if we've disabled
179 2009-05-12 Zoltan Varga <vargaz@gmail.com>
181 * collection.c (collection_thread): Get rid of all the ifdefs and
182 gcc attributes, simply return NULL.
184 2009-05-11 Zoltan Varga <vargaz@gmail.com>
186 * shared.c: Applied patch from Koushik K. Dutta (koush@koushikdutta.com).
187 Fix the build on android.
189 2009-05-09 Miguel de Icaza <miguel@novell.com>
191 * messages.c: Split the scan into common and uncommon messages to
192 allow the messages that are not produced by Mono to be removed on
195 * messages.c (message_string): instead of having a gigantic switch
196 table, use a sorted structure in memory and do a binary search on
199 This reduces the runtime size by 49k and the debugging symbols by
202 2009-04-29 Gonzalo Paniagua Javier <gonzalo@novell.com>
204 * sockets.c: don't display a warning when connect() fails because the
205 socket was closed in another thread.
207 2009-04-23 Rodrigo Kumpera <rkumpera@novell.com>
209 * shared.c: Fix a bunch of memleaks.
211 2009-03-27 Zoltan Varga <vargaz@gmail.com>

219 2009-02-22 Robert Jordan <robertj@gmx.net>
221 * sockets.c: implement WSASend/WSARecv using sendmsg/recvmsg.
224 Code is contributed under MIT/X11 license.
226 2009-02-20 Gonzalo Paniagua Javier <gonzalo@novell.com>
228 * events.c: fix event_signal and namedevent_signal to actually signal
231 2009-02-12 Gonzalo Paniagua Javier <gonzalo@novell.com>
233 * io.c: EXDEV when moving directories fails now without creating a
234 file in the destination.
237 2009-02-09 Zoltan Varga <vargaz@gmail.com>
239 * wait.c (WaitForMultipleObjectsEx): Initialize poll variable.
241 2009-02-05 Miguel De Icaza <miguel@novell.com>
243 * sockets.c (_wapi_setsockopt): SO_REUSEPORT is needed also on
244 MacOS X. Fixes bug #471292
246 2009-01-29 Zoltan Varga <vargaz@gmail.com>
248 * shared.c: Fall back to file based shared storage if shm_open () fails
249 because /dev/shm is not mounted.
251 * shared.c: Add an alternative implementation using shared memory instead of
252 files. This fixes problems where the mono process would spin up the disk
253 every x secs on laptops. Fixes #434566, #415373 and #321949.
255 2009-01-16 Miguel de Icaza <miguel@novell.com>
257 * sockets.c (WSASend): Fix memory leak, and optimize for the case
260 This should really use writev or sendmsg to use the kernel
261 scatter/gather facility instead of emulating it by copying buffers.
263 2009-01-26 Rodrigo Kumpera <rkumpera@novell.com>
265 * critical-sections.h (Enter/LeaveCriticalSection): Show
266 helpfull warning messages before crashing.
268 2009-01-26 Rodrigo Kumpera <rkumpera@novell.com>
270 * handles-private.h (_wapi_handle_set_signal_state): Show
271 helpfull warning messages before crashing.
273 2009-01-26 Jeffrey Stedfast <fejj@novell.com>
275 * mono-mutex.[c,h]: Removed GPLv2 copyright notice which should
278 2009-01-20 Rodrigo Kumpera <rkumpera@novell.com>
280 * threads.c: Add wapi_current_thread_desc that produces
281 a string representation of the current thread state.
283 * threads.h: Export wapi_current_thread_desc.
285 2009-01-18 Zoltan Varga <vargaz@gmail.com>
287 * io.c (GetDiskFreeSpaceEx): Applied patch from Koushik Dutta
288 (koush@koushikdutta.com). Disable this on android.
290 2009-01-16 Rodrigo Kumpera <rkumpera@novell.com>
292 * handles.c (_wapi_handle_timedwait_signal_handle): Don't use the
293 set_wait_handle/clear_wait_handle machinery for alertable waits in
294 case of non-alertable waits.
296 Non-alertable waits must continue and wait on the cond as this will
297 release the lock. Otherwise this will cause a deadlock as anyone trying
298 to pulse the cond will block trying to acquire the said lock because
299 the thread in non-alertable wait will be busy looping in WaitForSingleObjectEx
300 or similar function, never releasing the lock.
302 Thou this fixes quite a few of the hangs introduced by non-pooling alertable
303 waits, the long term plan is to verify if all non-alertable waits really need
306 2009-01-14 Zoltan Varga <vargaz@gmail.com>
308 * handles-private.h (_wapi_handle_set_signal_state): Set the signalled state
309 of the handle while locking the global signal cond mutex.
311 * wait.c (WaitForMultipleObjectsEx): Check the signalled state of handles
312 inside the critical section before waiting, otherwise we could go to waiting
313 even when the handles are already signalled.
315 2009-01-13 Zoltan Varga <vargaz@gmail.com>
317 Reapply r122913, this time handling processes by falling back to polling.
319 * handles.c: Rework the way the global signal stuff is handled: instead of
320 allocating a separate mutex/condvar pair for it, allocate a normal handle.
321 This way, it can reuse the alertable waiting code, allowing
322 WaitForMultipleObject to work without polling.
324 2009-01-09 Miguel de Icaza <miguel@novell.com>
326 Incorporate a few patches from Paolo, slightly modified:
328 * handles.c (_wapi_handle_check_share): On non-Linux systems, do
329 not even compile in the code that scans for /proc/fd, and go
330 directly to the fallback function.
332 2009-01-09 Paolo Molaro (lupus@ximian.com)
334 * handles.c: Do not include some header files in platforms that
337 2009-01-09 Miguel de Icaza <miguel@novell.com>
339 * messages.c: Eliminate a warning.
341 2009-01-09 Paolo Molaro (lupus@ximian.com)
343 * error.c: On some platforms that do not define these variables,
346 * security.c, io-private.h: Only include some headers if they
349 * sockets.c, sockets.h: do not import on this header files that
350 are only consumed internally in sockets.c.
352 2009-01-09 Zoltan Varga <vargaz@gmail.com>
354 * threads.c (_wapi_thread_apc_pending): Check for thread->wait_handle ==
355 INTERRUPTION_REQUESTED_HANDLE too.
356 (wapi_interrupt_thread): Rework the comments, the thread is no longer
357 required to call QueueUserAPC to make the wait functions return.
359 * threads.c handles.c threads-internal.h: Implement alertable waits without
362 2009-01-08 Geoff Norton <gnorton@novell.com>
364 * processes.c: Fix the osx version check to properly detect 10.5 v 10.4
366 2009-01-08 Christian Prochnow <cproch@seculogix.de>
368 * types.h: added WapiULargeInteger.
370 * uglify.h: added ULARGE_INTEGER, PULARGE_INTEGER.
372 * io.h: added WapiDriveType, added method declarations
373 for GetDiskFreeSpaceEx and GetDriveType
375 * io.c: added GetDiskFreeSpaceEx() to query disk size
376 and free space via statvfs or statfs system call.
377 added GetDriveType to query drive type via /etc/mtab or /etc/mnttab.
379 2009-01-07 Geoff Norton <gnorton@novell.com>
381 * processes.c: Properly implement support for Process.Modules on OSX.
382 Fixes OSX on nunit 2.4
384 2009-01-07 Rodrigo Kumpera <rkumpera@novell.com>
386 * io.c (GetCurrentDirectory): Avoid calling g_get_current_dir straight
387 away as it doesn't handle ENAMETOOLONG correctly. As a bonus we avoid
388 allocating memory in the common path.
390 2009-01-07 Geoff Norton <gnorton@novell.com>
392 * processes.c: Only use open -W on OSX 10.5+. Patch from
395 2008-12-19 Bill Holmes <billholmes54@gmail.com>
397 * processes.c (get_module_name) : adjust size for unicode characters.
399 Code is contributed under MIT/X11 license.
401 2008-11-21 Zoltan Varga <vargaz@gmail.com>
403 * atomic.h: Applied patch from Mihai Chelaru <kefren@ngnetworks.ro>. Add

417 * wait.h : Adding method declaration for WaitForInputIdle.
419 * wait.c : Adding implementation for WaitForInputIdle.
421 Code is contributed under MIT/X11 license.
423 Fri Oct 17 15:23:00 CEST 2008 Paolo Molaro <lupus@ximian.com>
425 * processes.c: patch from Geoff Norton (gnorton@novell.com) to
426 strdup the open program on OSX (bug #431811).
428 2008-10-10 Gonzalo Paniagua Javier <gonzalo@novell.com>
430 * versioninfo.c: remove the use of g_strdown.
432 2008-09-25 Dick Porter <dick@ximian.com>
434 * wait.c: Make sure we keep references to handles we're waiting
435 for. Fixes bug 424851.
437 2008-07-29 Dick Porter <dick@ximian.com>
439 * processes.c (get_module_name): Make a last-ditch effort to
440 figure out the process name. Fixes bug 413723, patch by Casey
441 Marshall <casey.s.marshall@gmail.com>
443 2008-07-28 Dick Porter <dick@ximian.com>
445 * handles.c (_wapi_handle_count_signalled_handles): Remove an
446 unmatched _wapi_handle_ref(). Fixes bug 410743.
448 2008-07-15 Rodrigo Kumpera <rkumpera@novell.com>
450 * versioninfo.c (map_pe_file): Fix memory leak.
452 2008-07-01 Zoltan Varga <vargaz@gmail.com>
454 * process-private.h (_WAPI_PROCESS_UNHANDLED_PID_MASK): Fix the amd64 build.
456 2008-06-27 Dick Porter <dick@ximian.com>
458 * processes.c: Implement a form of process pseudo-handle to allow
459 non-mono processes to be manipulated. Fixes bug 313231.
461 * wait.c: Check for process pseudo-handles and fail if an attempt
462 is made to wait on one.
464 2008-06-19 Dick Porter <dick@ximian.com>
466 * sockets.c: Implement WSASend() and WSAReceive().
468 2008-06-02 Dick Porter <dick@ximian.com>
473 * messages.c: Implement FormatMessage, fixes bug 321827.
475 2008-05-29 Dick Porter <dick@ximian.com>
477 * sockets.c (socket_close): Clear any saved errors
478 (_wapi_connect): Don't save EWOULDBLOCK errors here, as that
479 breaks async connects. (Bug 377589 test case broken by the
480 previous fix to bug 356552)
482 2008-05-25 Zoltan Varga <vargaz@gmail.com>
484 * thread-private.h (struct _WapiHandle_thread): Remove 'owner_pid' field. Reorder
485 fields so this struct (which is the biggest of the handle structs) takes less
488 * threads.c (QueueUserAPC): Make this function signal safe by adding some
489 restrictions on its usage.
491 2008-05-14 Zoltan Varga <vargaz@gmail.com>
493 * mono-mutex.h: Get rid of the #ifdef __cplusplus defines, use G_BEGIN_DECLS
496 2008-05-07 Dick Porter <dick@ximian.com>
498 * io.c (FindNextFile): Handle symlinks correctly. Fixes bug
501 2008-04-25 Zoltan Varga <vargaz@gmail.com>
503 * handles.c (_wapi_handle_check_share): Fix a crash introduced by the lazy
504 creation of wapi handle slots.
506 2008-04-24 Zoltan Varga <vargaz@gmail.com>
508 * handles.c (shared_init): Align _wapi_fd_reserve to a multiple of
509 _WAPI_HANDLE_INITIAL_COUNT to avoid a problem when allocating handles.
511 2008-04-23 Zoltan Varga <vargaz@gmail.com>
513 * handles.c: Initialize the handle array entries on demand to save memory.
515 * wapi-private.h (_WAPI_HANDLE_INITIAL_COUNT): Decrease this to 256 to save
518 * handles-private.h (_WAPI_PRIVATE_MAX_SLOTS): Increase this to 1024*16 to
519 compensate for the decrease in _WAPI_HANDLE_INITIAL_COUNT.
521 * threads.c: Use #ifdef instead of #if for checking for valgrind/memcheck.h.
523 2008-04-22 Dick Porter <dick@ximian.com>
525 * wapi_glob.c (globextend): Comment out the code using ARG_MAX, as
526 that is broken on the latest opensuse.
528 2008-04-21 Dick Porter <dick@ximian.com>
530 * io.c (DeleteFile): Disable for now the bug fix for 323389, it's
531 breaking too much other stuff.
533 2008-04-20 Geoff Norton <gnorton@novell.com>
535 * processes.c: Fix the _NSGetEnviron define to prevent an impropoer
538 2008-04-18 Miguel de Icaza <miguel@novell.com>
540 * Applied patch from Dick Porter from bug #380649
542 2008-04-17 Dick Porter <dick@ximian.com>
544 * io.c (DeleteFile): Check file shares before deleting a file.
547 2008-04-17 Dick Porter <dick@ximian.com>
549 * io.c (DeleteFile): Return ERROR_ACCESS_DENIED if the file is
550 readonly. Fixes bug 378229.
552 2008-04-11 Geoff Norton <gnorton@novell.com>
554 * processes.c: The global extern environ doesn't exist on Mac. We
555 need to call NSGetEnviron instead.
557 2008-04-08 Dick Porter <dick@ximian.com>
559 * processes.c (CreateProcess): Improve the managed binary support,
560 so it works when the executable is passed in as the appname.
563 2008-04-04 Dick Porter <dick@ximian.com>
565 * io.c (MoveFile): Check file shares before moving a file. Fixes
568 2008-04-04 Dick Porter <dick@ximian.com>

577 * versioninfo.c: 64bit fixes
579 2008-04-03 Dick Porter <dick@ximian.com>
581 * io-portability.c (_wapi_basename, _wapi_dirname): Only turn \
582 into / when MONO_IOMAP is in effect. Fixes bug 346123.
584 2008-04-03 Dick Porter <dick@ximian.com>
586 * timefuncs.c (GetTickCount): Use mono_msec_ticks(), see bug
589 2008-04-01 Dick Porter <dick@ximian.com>
591 * versioninfo.c (get_string_block): Refine the fix for bug 354856
592 (r93661) so that it also fixes the new part of bug 374600.
594 2008-03-28 Dick Porter <dick@ximian.com>
596 * processes.c (GetExitCodeProcess): Check if a process has exited
597 and recorded it's exit code, before seeing if the process is
598 signalled. Fixes bug 325463.
600 2008-03-27 Dick Porter <dick@ximian.com>
602 * processes.c (match_procname_to_modulename): Check the whole
603 process name first, in case it is recorded as an absolute path.
606 2008-03-27 Dick Porter <dick@ximian.com>
608 * processes.c (ShellExecuteEx): Grotty kludge to work around
609 unpleasant feature in g_shell_parse_argv() where it treats '#'
610 embedded in a filename as a comment marker, and throws away the
611 rest of the line. When we're directly opening URLs quote the
612 filename, to avoid this. Fixes bug 371567.
614 2008-03-25 Dick Porter <dick@ximian.com>
616 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment file layout
619 * threads.c: Make thread handles private to the process that owns
622 2008-03-22 Kornél Pál <kornelpal@gmail.com>
624 * io-layer.h: Windows: Rename GetProcessId to __GetProcessId for targets not
625 supporting it. This fixes MSVC build with new Windows SDKs that declare
626 GetProcessId unconditionally.
628 2008-03-20 Kornél Pál <kornelpal@gmail.com>
630 * io-layer.h: Removed Windows version macros.
632 Thu Mar 13 16:24:53 CET 2008 Paolo Molaro <lupus@ximian.com>
634 * processes.c: properly check for executable files (fixes bug #368829).
636 2008-02-05 Dick Porter <dick@ximian.com>
638 * versioninfo.c (VerLanguageName): Implement VerLanguageName.
640 2008-01-31 Bill Holmes <billholmes54@gmail.com>
641 * processes.c (match_procname_to_modulename) : Added to check if the last
642 part of module name is equal to the process name.
644 * processes.c (EnumProcessModules) : Changed the first entry in the returned
645 modules array (the process module) to be populated from the entry found
648 * processes.c (get_module_name & GetModuleInformation) : In the case where
649 the module passed in is NULL, search the /proc/<PID>/maps for a name that
650 matches the process name to populate the return information.
654 2008-01-29 Zoltan Varga <vargaz@gmail.com>
656 * security.c (RevertToSelf): Make this return TRUE if impersonating is not
659 * sockets.c (_wapi_connect): Add a workaround to a solaris x86 problem where
660 getsockopt (SO_ERROR) doesn't return an error code after connect () fails. Fixes
663 2008-01-23 Dick Porter <dick@ximian.com>
665 * versioninfo.c (get_string_block): When stepping over the
666 StringTable block, do not read an extra block at the end. Fixes
667 the new part of bug 354856.
669 2008-01-19 Dick Porter <dick@ximian.com>
671 * versioninfo.c (get_stringtable_block): Cope when the StringTable
672 block is first in the resources data, and we just need to step
673 over it. Fixes bug 354856.
675 2008-01-16 Dick Porter <dick@ximian.com>
677 * threads.c (_wapi_thread_set_termination_details): Move the
678 thread abandonment to outside the shared handle lock. Fixes bug
681 2008-01-16 Dick Porter <dick@ximian.com>
683 * versioninfo.c (VerQueryValue): Include trailing null in returned
684 string length, for MS compatibility.
686 2008-01-09 Dick Porter <dick@ximian.com>
688 * versioninfo.c (get_ptr_from_rva, scan_resource_dir): Make it
689 work on big-endian systems.
690 (scan_resource_dir): Copy the resource directory entry and
691 byteswap if necessary so it works big-endian. This fixes bug
692 345972 for real this time.
693 (VerQueryValue): String values set the length to the number of
694 unicode chars, but the data length reported was already correct so
695 don't halve it again. Fixes the previous fix for bug 345972.
696 (GetFileVersionInfo): On big-endian systems, scan the resource
697 data and turn all unicode strings into UTF-16BE. FileVersionInfo
698 now works big-endian.
700 2008-01-04 Dick Porter <dick@ximian.com>
702 * versioninfo.c (VerQueryValue): Returned buffer length counts
703 chars not bytes for string data. Fixes bug 345972 again.
704 (get_enclosing_section_header): Make sure values read are treated
705 as LE. Fixes crash on ppc reported in bug 345972.
707 2007-12-17 Mark Probst <mark.probst@gmail.com>
709 * threads.c: Guard against a race condition involving
710 thread_hash_key that can occur during shutdown.
712 2007-12-08 Zoltan Varga <vargaz@gmail.com>
714 * processes.c: Include sys/mkdev.h if exists. Fixes solaris x86 build.
716 2007-12-06 Dick Porter <dick@ximian.com>
718 * versioninfo.c: Resource language values must be compared in a
719 'case'-insensitive manner. Fixes bug 345972.
721 2007-12-05 Dick Porter <dick@ximian.com>
723 * io.c (CreateFile): Create files with mode 0666 (&~umask) by
724 default. Fixes bugs 325299 and 337040.
726 2007-11-22 Dick Porter <dick@ximian.com>
728 * critical-sections.h (EnterCriticalSection): Reinstate the
729 asserts in the devel branch, so any problems aren't obscured.
731 2007-11-22 Dick Porter <dick@ximian.com>

734 systems. Fixes bug 343353.
736 2007-11-21 Dick Porter <dick@ximian.com>

739 /proc/<pid>/maps parsing to avoid using glib functions only
740 available since 2004.
741 (load_modules): Check for duplicates before adding a module to the
744 2007-11-15 Dick Porter <dick@ximian.com>
746 * processes.c (load_modules): Don't bother if we don't have
747 g_strsplit_set() and g_strv_length(). Allows building against old
749 (EnumProcessModules): Don't miss the first module returned by
752 2007-11-15 Dick Porter <dick@ximian.com>
754 * processes.c: Implement process module support by reading from
755 /proc if it's available.
758 * versioninfo.c: New functions to implement PE file version info
761 2007-11-08 Dick Porter <dick@ximian.com>
763 * critical-sections.h (EnterCriticalSection): Disable the critical
764 section asserts for the release branch
766 2007-11-05 Kornél Pál <kornelpal@gmail.com>
768 * io-layer.h: Added includes for run-time GetProcessId API detection for
771 2007-10-26 Dick Porter <dick@ximian.com>
773 * shared.c (_wapi_shm_file_open): Set the umask when opening
774 shared files, so restrictive defaults don't prevent subsequent
775 processes re-opening them.
777 2007-10-18 Zoltan Varga <vargaz@gmail.com>
779 * atomic.h (InterlockedCompareExchange): Fix the ia64 version so it works for
780 negative values too. Hopefully fixes #332700.
782 2007-09-26 Dick Porter <dick@ximian.com>
784 * io-portability.c (_wapi_io_scandir): Only update the error
785 status of glob() when performing a secondary glob() if the first
786 returned an error. Fixes bug 325107.
788 2007-09-12 Marek Habersack <mhabersack@novell.com>
790 * io-portability.c: options_init moved to
791 utils/mono-io-portability.c
792 Do not initialize portability helpers here, it's done in
794 find_file and find_in_dir moved to utils/mono-io-portability.c
796 2007-09-09 Robert Jordan <robertj@gmx.net>
798 * sockets.c (_wapi_setsockopt): Add support for FreeBSD multicast
799 sockets. Fixes #81891.

818 2007-09-03 Atsushi Enomoto <atsushi@ximian.com>
820 * processes.c, processes.h: added CreateProcessWithLogonW(). For now
821 it just calls CreateProcess().
822 * io-layer.h : CreateProcessWithLogonW() requires WINVER 0x0500
825 2007-08-23 Robert Jordan <robertj@gmx.net>
827 * processes.[c|h]: Implement Get|SetPriorityClass ().
828 Code is contributed under MIT/X11 license.
830 Tue Aug 21 20:08:09 CEST 2007 Paolo Molaro <lupus@ximian.com>
832 * io.c: made convert_arg_to_utf8() and write_file() static.

849 * processes.c: implemented query for user/system times using
852 2007-08-10 Dick Porter <dick@ximian.com>
854 * sockets.c (_wapi_getsockopt, _wapi_setsockopt): Check the option
855 level as well as the name when mangling some of the values. Fixes
858 2007-08-02 Dick Porter <dick@ximian.com>
860 * sockets.c: Changes in error handling, and move the SO_REUSEADDR
861 setting from metadata/socket-io.c.
863 2007-08-01 Dick Porter <dick@ximian.com>
865 * io-portability.c (_wapi_io_scandir): Special-case patterns
866 ending in '.*' so that files with no extension are also matched.
870 * wapi_glob.c: Reinstate WAPI_GLOB_APPEND, and add
871 WAPI_GLOB_UNIQUE to avoid matching the same entry twice when
874 2007-07-26 Dick Porter <dick@ximian.com>
879 * critical-sections.c:
881 * critical-section-private.h:
884 * error.c: Clean up TLS and pthreads structures. Finishes off bug

899 * io.c (MoveFile): Fix a leak.
901 Fri Jul 13 12:46:15 CEST 2007 Paolo Molaro <lupus@ximian.com>
903 * handles-private.h, handles.c, thread-private.h, threads.c,
904 uglify.h, wait.c: temporarily revert the alertable wait changes
905 (r79386) until the deadlock issues are fixed.
907 2007-06-22 Dick Porter <dick@ximian.com>
909 * shared.c: The non-shared mutexes weren't being initialised properly
910 on macos. Fixes bug 81929.
912 2007-06-13 Randolph Chung <tausq@debian.org>
914 * atomic.h: Enable for all hppa targets.
915 * Makefile.am: rename hppa_atomic.s to hppa_atomic.S so the preprocessor
917 * hppa_atomic.s: Renamed to ...
918 * hppa_atomic.S: ... and updated to work on both HPUX and Linux.
920 2007-06-13 Dick Porter <dick@ximian.com>
922 * handles.c (timedwait_signal_wait_cond): Alertable waits on
923 private handles are now interrupted by signalling the same
924 condition that would end the wait if the handle became signalled,
925 rather than polling. (Shared handles still have to poll.)
927 * threads.c (_wapi_thread_queue_apc): Interrupt the thread if it's
930 * handles-private.h (_wapi_handle_current_thread_set_waiting_on):
931 Helper functions to inform the APC queuing functions when threads
932 are waiting for handles, and to interrupt the wait.
934 * wait.c (WaitForMultipleObjectsEx): Need to tell the handle
935 waiting functions if any of the handles in question are shared
937 2007-06-06 Miguel de Icaza <miguel@novell.com>
939 * processes.c (is_managed_binary): Fix for OSX.
941 2007-06-06 Wade Berrier <wberrier@novell.com>
943 * atomic.h (InterlockedExchangePointer): cast to pointer to to silence
944 compiler warnings (autobuild fails the build on this type of warning)
946 2007-05-21 Dick Porter <dick@ximian.com>
948 * io-portability.c (_wapi_g_dir_open): Don't propagate any errors
949 from the second call to g_dir_open, preserve the original error if
950 the second call still fails but clear the error if it succeeds.
952 2007-05-10 Dick Porter <dick@ximian.com>
954 * sockets.c (_wapi_recvfrom): Refine the fix to bug 75705 so EINTR
955 isn't returned if the remote end shuts down cleanly. Fixes zmd
956 and the second example in bug 75705.
958 2007-04-26 Dick Porter <dick@ximian.com>
960 * shared.c (_wapi_shm_semaphores_init): Need to check
961 MONO_DISABLE_SHM in this entry point, as it's called before
962 _wapi_shm_attach(). Fixes bug 81436.
964 2007-04-24 Dick Porter <dick@ximian.com>
966 * sockets.c (_wapi_recvfrom, socket_close): Force recvfrom() to
967 error if the socket is closed while the receive is blocking.
970 2007-04-13 Dick Porter <dick@ximian.com>
973 * shared.c: Complete the reimplementation of disabling of shared
974 memory, by not allocating sysv semaphores when shm disabling has
975 been requested (either at compile time or run time.)
977 * processes.c (CreateProcess): Don't synchronize locking across
978 processes when forking, when shared memory has been disabled.
980 2007-04-06 Andreas Faerber <andreas.faerber@web.de>
983 * wapi_glob.c: remove reference to sys/cdefs.h, use glib instead.
986 2007-04-05 Dick Porter <dick@ximian.com>
989 * io-portability.c (_wapi_io_scandir): Moved from io.c, and
990 changed to use a cut-down version of glob(3) that has been
991 extended to match with case-insensitivity if needed.
994 * wapi_glob.c: Cut down implementation of glob(3), based on
997 2007-03-22 Dick Porter <dick@ximian.com>
999 * sockets.c (_wapi_connect): Do additional checks when connect(2)
1000 fails, because some systems don't let it be restarted. Patch
1001 based on one submitted by Robert S Wojciechowski <robertw@ssgx.com>,
1004 2007-03-09 Jonathan Chambers <joncham@gmail.com>
1006 * io-layer.h: Remove UNICODE and _UNICODE defines as
1007 these are done by configure.in now.

1015 2007-03-05 Wade Berrier <wberrier@novell.com>
1017 * atomic.h: atomic fixes from Michael Matz for for s390
1018 and s390x ( bnc #237611 and bxc #80892 )
1020 2007-03-05 Miguel de Icaza <miguel@novell.com>
1022 * io.c (CreateFile): Use FILE_ATTRIBUTE_TEMPORARY to mean 0600
1023 permissions. For 80688
1025 (MoveFile): Use errno_copy here, just to avoid a potential
1026 errno-changing code in the future from g_free.
1028 Also, ignore EXDEV errors as they are handled immediately after
1029 (avoid printing out an error).
1033 Mon Feb 12 15:50:24 CET 2007 Paolo Molaro <lupus@ximian.com>
1035 * shared.c: exit if semaphores can't be created (bug #80616).
1037 2007-02-01 Geoff Norton <gnorton@customerdna.com>
1039 * collection.c: NetBSD doesn't define PTHREAD_STACK_MIN.
1041 2007-01-26 Dick Porter <dick@ximian.com>
1044 * sockets.c (_wapi_getsockopt): Windows seems to not reset
1045 SO_ERROR values when they're read, contrary to the documentation.
1046 Fixes the new issues raised in bug 79878 (example in C showing
1047 winsock behaviour attached to that bug.)
1049 2007-01-15 Mark Mason <mason@broadcom.com
1051 * atomic.h: add locking primitives for MIPS.
1053 2007-01-11 Dick Porter <dick@ximian.com>
1055 * sockets.c (_wapi_connect): Don't do the SO_BROADCAST setting
1056 here, do it in managed code instead.
1057 (_wapi_getsockopt): SO_RCVTIMEO and SO_SNDTIMEO use struct
1058 timeval, which has a microsecond field, not milliseconds.
1059 (_wapi_setsockopt): ditto.
1060 (_wapi_setsockopt): Halve the SO_SNDBUF and SO_RCVBUF values on
1061 Linux, as the kernel doubles whatever we set.
1062 (_wapi_socket): Save socket domain, type and protocol so it can be
1064 (socket_disconnect): Implement socket disconnect (closing the
1065 socket, but keeping the file descriptor.)
1066 (wapi_disconnectex): A basic implementation of DisconnectEx().
1067 (wapi_transmitfile): A very basic implementation of
1069 (WSAIoctl): Implement the SIO_GET_EXTENSION_FUNCTION_POINTER
1072 * socket-private.h (struct _WapiHandle_socket): Record socket
1073 domain, type and protocol info so it can be duplicated later.
1075 * sockets.h (WSAID_DISCONNECTEX,WSAID_TRANSMITFILE): Structures
1076 and defines needed to look up the DisconnectEx() and
1077 TransmitFile() functions by GUID.
1079 * error.c (errno_to_WSA): Change ETIMEDOUT mapping to
1080 WSAETIMEDOUT; add EDESTADDRREQ.
1082 * io-layer.h: Need mswsock.h on windows now.
1084 2007-01-04 Miguel de Icaza <miguel@novell.com>
1086 * io-portability.c (find_file): Fix a coverity warning (scanning
1089 2006-12-31 Miguel de Icaza <miguel@novell.com>
1091 * io-portability.c (find_file): Do not abort if an empty filename
1092 has been passed. This fixes the case where MONO_IOMAP=all would
1093 assert if Directory.Exists ("") was called.
1095 Mon Dec 18 14:54:37 CET 2006 Paolo Molaro <lupus@ximian.com>
1097 * processes.c: moved a free on the error path.
1099 Thu Dec 14 21:42:39 CET 2006 Paolo Molaro <lupus@ximian.com>
1101 * processes.c: fixed a few memory leaks when executing
1104 Mon Nov 27 13:12:17 GMT 2006 Paolo Molaro <lupus@ximian.com>

1108 2006-11-23 Dick Porter <dick@ximian.com>
1110 * process-private.h (struct _WapiHandle_process): Add 'waited'
1113 * processes.c (process_wait): Check the 'waited' parameter not the
1114 signalled state when testing if a process has already been waited
1115 for, as the child process itself may set signalled when exiting.
1118 * wapi-private.h (_WAPI_HANDLE_VERSION): Bump shared data version
1120 * shared.c: Now the shared data version has been incremented we
1121 can set the counter semaphore initial value correctly
1123 2006-11-22 Dick Porter <dick@ximian.com>
1125 * processes.c (process_wait): Cope when the background process
1126 reaper gets the process we were waiting for. Special case for
1127 waiting for our own process to exit. Fixes bug 77736.
1129 2006-11-17 Dick Porter <dick@ximian.com>
1131 * processes.c: Fix const correctness and typos that caused memory
1134 2006-11-17 Miguel de Icaza <miguel@novell.com>
1136 * processes.c (ShellExecuteEx): Check error after CreateProcess,
1137 thanks to Dick for pointing this out.
1139 2006-11-16 Miguel de Icaza <miguel@novell.com>
1141 * processes.c (ShellExecuteEx): If we fail to create a process in
1142 ShellExecute, then try to use the xdg-open command, and if that
1143 fails, try to use the gnome-open command,
1145 Refactor the code so that we do not have to duplicate all this
1146 code, but instead use a ucs2-aware version of the code to do
1149 2006-11-13 Dick Porter <dick@ximian.com>
1151 * io.c (_wapi_stat_to_file_attributes): If the file is a symlink
1152 add the FILE_ATTRIBUTE_REPARSE_POINT flag. This is an attempt to
1153 follow the specs for the windows symlink support, but will
1154 probably have to be reworked when I have test data from a vista
1155 machine. Fixes bug 79887.
1157 2006-11-11 Miguel de Icaza <miguel@novell.com>
1159 * handles.c (CloseHandle): Cope here with the new value
1160 INVALID_HANDLE_VALUE set on handles.
1162 * processes.c (CreateProcess): Initialize the value of hThread to
1163 be INVALID_HANDLE_VALUE on failure, not to be NULL. Improvement
1166 2006-11-09 Dick Porter <dick@ximian.com>
1168 * sockets.c (_wapi_select): Do some sanity checking on the
1169 fd_sets, to avoid file descriptors > FD_SETSIZE.
1170 (_wapi_FD_CLR, _wapi_FD_ISSET, _wapi_FD_SET): Avoid file
1171 descriptors > FD_SETSIZE.
1173 2006-10-27 Dick Porter <dick@ximian.com>
1175 * io.c (GetFileAttributes): Force symlinks to directories to be
1176 returned as a regular file. Fixes bug 79733.
1178 2006-10-18 Miguel de Icaza <miguel@novell.com>
1180 * io-portability.c (find_in_dir): First string dup, then closedir.
1182 2006-10-12 Dick Porter <dick@ximian.com>
1184 * processes.c (_wapi_process_reap): Unref a process handle if we
1185 reaped it, found by Zoltan. Fixes bug 79286.
1186 (process_wait): Don't wait again if we've already waited for a
1189 2006-10-11 Sergey Tikhonov <tsv@solvo.ru>
1191 * atomic.h: Fix atomic decrement.
1193 * mini/cpu-alpha.md: Use native long shift insts
1195 * mono/mono/mini/tramp-alpha.c: Implemented
1196 mono_arch_patch_delegate_trampoline method
1198 * Started work on using global registers

1205 2006-10-09 Zoltan Varga <vargaz@gmail.com>
1207 * handles.c (timedwait_signal_poll_cond): Add an alertable parameter, and if it
1208 is FALSE, avoid busy waiting.
1210 * wait.c: Add an alertable parameter to the wait routines.
1212 2006-10-06 Miguel de Icaza <miguel@novell.com>
1214 * io-portability.c (find_file): Rename from
1215 MONO_IO_PORTABILITY_HELP to MONO_IOMAP.
1217 2006-10-03 Dick Porter <dick@ximian.com>
1220 * io-portability.c: Optional portability helpers and wrapped
1221 system calls to try to cope with windows filenames in
1224 * io.c: Use the wrapped system calls
1226 2006-09-01 Zoltan Varga <vargaz@gmail.com>
1228 * critical-sections.h critical-sections.c: Make Enter/LeaveCriticalSection a macro
1229 since they are perf critical.
1231 * atomic.h: Applied patch from Jakub Boqusz <qboosh@pld-linux.org>.
1232 Add atomic ops implementation for alpha.
1234 2006-08-11 Dick Porter <dick@ximian.com>
1236 * processes.c (_wapi_process_reap): Avoid a deadlock by setting
1237 process termination details in an outer loop, not the
1238 _wapi_search_handle() one.
1240 2006-08-10 Dick Porter <dick@ximian.com>
1242 * threads.c (_wapi_thread_queue_apc)
1243 (_wapi_thread_dispatch_apc_queue): Use a process-local mutex here
1244 instead of the cross process semaphore. We already check that
1245 access to the APC queue is within the owning process so there's no
1246 need to protect from other processes. Avoids a global deadlock
1247 when a thread is aborted while it holds the handle semaphore
1249 (_wapi_thread_apc_pending): Hide an annoying message which can
1250 happen if a thread handle has been blown away at process shutdown
1251 while it is in an alertable wait.
1253 Both problems seen while shutting down monodevelop.
1255 2006-07-25 Dick Porter <dick@ximian.com>
1257 * shared.c (_wapi_shm_file): Remove '/' characters from the uname
1258 results. Fixes bug 78917.
1260 2006-07-20 Dick Porter <dick@ximian.com>
1262 * threads.c (_wapi_thread_set_termination_details): Improve the
1263 test for already-disposed thread handles, and hold the lock around
1264 the mutex abandoning.
1266 2006-07-17 Dick Porter <dick@ximian.com>
1268 * processes.c (CreateProcess): Don't change directory unless a new
1269 one has been specified. Fixes bug 78751.
1271 2006-07-06 Dick Porter <dick@ximian.com>
1273 * io.c (_wapi_stat_to_file_attributes): Do a better job at
1274 figuring out the file attributes
1275 (_wapi_set_last_path_error_from_errno): New helper function to
1276 turn errno into w32 error codes that handles the differences
1277 between file and directory errors
1278 (file_setendoffile): Try turning off the extra write used to
1279 extend files, because we probably don't need it on any modern
1280 platform. If it is needed though, we also need to lseek the file
1282 (CreateFile): Treat character-special devices as a console handle,
1283 because they can't be seeked
1284 (CopyFile): If fail_if_exists is set, then the destination needs
1285 to be opened with O_EXCL
1286 (CopyFile): If fail_if_exists is not set and the destination
1287 already exists, then we should set the ERROR_ALREADY_EXISTS error
1288 even though we return success
1289 (stdhandle_create): STD_INPUT_HANDLES cannot be written to
1290 (GetStdHandle): Rework without using mono_once, so console handles
1291 can be properly closed and reopened.
1292 (mono_io_scandir): Only override errno with EACCES when the
1293 directory actually exists
1294 (FindFirstFile): Set ERROR_FILE_NOT_FOUND when no files are
1296 (FindClose): Cope with NULL handles
1297 (CreateDirectory): When the target already exists, just return an
1298 error. It's the caller's job to figure out what to do.
1299 (SetCurrentDirectory): Cope with a NULL path
1300 (RemoveDirectory, GetFileAttributes, GetFileAttributesEx,
1301 SetFileAttributes, FindFirstFile, DeleteFile, MoveFile, CopyFile,
1302 CreateFile): Set path error correctly
1304 * handles.c (CloseHandle): Kludge to try and cope with passing a
1307 * error.h: Add NO_ERROR as an alternative to ERROR_SUCCESS
1309 * uglify.h: Added some more typedefs
1311 2006-07-05 Dick Porter <dick@ximian.com>
1313 * io.c (GetFileAttributes, GetFileAttributesEx): Cope with
1314 dangling symlinks. Fixes bug 78664.
1316 2006-06-23 Dick Porter <dick@ximian.com>
1318 * handles.c (handle_cleanup):
1319 * threads.c: Clean up threads properly when we're forcibly
1320 removing the handle entries from the shared file in
1321 handle_cleanup(). Fixes bug 78241, for real this time.
1323 2006-06-15 Neale Ferguson <neale@sinenomine.net>
1325 * atomic.h: More tinkering with InterlockedExchange/InterlockedCompareExchange
1328 2006-06-14 Neale Ferguson <neale@sinenomine.net>
1330 * atomic.h: Fix atomic exchange pointer operations for s390x - these
1331 were broken as they used 32-bit instructions rather than their 64-bit
1334 2006-06-14 Dick Porter <dick@ximian.com>
1336 * processes.c: Don't run the atexit handlers when bailing out
1339 2006-06-14 Dick Porter <dick@ximian.com>
1341 * wait.c: Fix stupid typo shown up by gcc 4.1.1, = not ==
1343 * handles-private.h:
1349 * collection.c: Fix a bunch of signed/unsigned warnings from gcc
1352 2006-06-09 Neale Ferguson <neale@sinenomine.net>
1354 * atomic.h: Fix atomic operations for s390x (not really broken
1355 but changed to use full 64-bit opcodes).
1357 2006-05-24 Dick Porter <dick@ximian.com>
1359 * processes.c (process_set_current): Don't take an extra reference
1360 if we have to create our own process handle. Fixes bug 78241
1363 * threads.c (_wapi_thread_signal_self): Renamed from
1364 _wapi_thread_abandon_mutexes, also sets the thread state to
1365 signalled and drops a reference. Called by the runtime when the
1366 main thread cleans itself up.
1368 * handles.c (handle_cleanup): As a last resort, unref every shared
1369 handle as the process is now exiting.
1371 2006-05-16 Dick Porter <dick@ximian.com>
1373 * processes.c (process_set_termination_details): Unref the handle
1374 when we've stored the exit details. Fixes the rest of 78241.
1376 2006-05-12 Dick Porter <dick@ximian.com>
1378 * threads.c: Implement pseudo handles, making GetCurrentThread()
1379 match MS behaviour. Notice when attached threads exit, and unref
1380 the handle. Fix usage of GetCurrentThread() in other places.
1382 * handles.c (DuplicateHandle): Implement a basic form of
1385 * wait.c: Fix usage of GetCurrentThread() throughout, and cope
1386 with pseudo handles.
1388 2006-04-26 Miguel de Icaza <miguel@novell.com>
1390 * io.c (file_close): Oops, do not use DeleteFile which expects
1391 unicode, instead use unlink directly
1393 Add support for the new FileOptions bits on .NET 2.0.
1395 It might be good if Dick reviews these changes.
1397 * io.c (file_close): If DeleteOnClose is set, then delete the file
1399 (CreateFile): Do not support encryption per user.
1401 If posix_fadvise exists, pass hints on sequential scan and random
1402 access. Did not figure out what WRITE_THROUGH maps to.
1404 2006-04-26 Dick Porter <dick@ximian.com>
1406 * sockets.c (WSAIoctl): Check the output buffer is valid before
1409 * handles.c (_wapi_search_handle): Set shared pointer if we find a
1410 shared handle that has been already opened.
1412 2006-04-21 Dick Porter <dick@ximian.com>
1414 * threads.c (GetCurrentThread): Reference the handle if we return
1415 an already-known thread.
1417 2006-04-07 Dick Porter <dick@ximian.com>
1419 * processes.c: Fix build for older glib.
1421 2006-04-06 Dick Porter <dick@ximian.com>
1423 * processes.c (CreateProcess): Add a reference to the child
1424 process' handle, so it won't be destroyed if this process closes
1425 its copy of the handle. Fixes bug 77393.
1427 * processes.c (process_set_current): Fall through to creating a
1428 new one if the handle lookup fails.
1430 * processes.c (_wapi_process_signal_self):
1431 * handles.c (handle_cleanup): The process is exiting, so set the
1432 handle state for this process to signalled. This should let other
1433 non-related processes wait for this handle.
1435 * handles.c (_wapi_search_handle): Don't search shared handles in
1438 * collection.c (collection_thread): No need to do a collection
1439 scan straight away, do the waiting first.
1441 2006-04-06 Dick Porter <dick@ximian.com>
1443 * shared.c: Fix parameters in semctl () call.
1445 2006-03-28 Zoltan Varga <vargaz@gmail.com>
1447 * atomic.h atomic.c: Applied patch from David S. Miller
1448 <davem@davemloft.net>: Reimplement Interlocked* primitives on sparc
1449 using CAS/CASx when __GNUC__, else we will fall back to the generic
1452 2006-03-27 Dick Porter <dick@ximian.com>
1454 * shared.c (_wapi_shm_file_open): Break out of a loop if the
1455 shared file is smaller than expected. (We loop a few times in
1456 case another process is in the middle of creating the file.)
1458 2006-03-22 Dick Porter <dick@ximian.com>
1463 * shared.c: Delete the semaphores and shared files when the last
1464 process has finished with them
1466 2006-03-15 Dick Porter <dick@ximian.com>
1474 * threads.c: Explicitly initialise the handle ops struct
1476 2006-03-14 Dick Porter <dick@ximian.com>
1478 * handles-private.h:
1481 * handles.c: Add a 'prewait' stage to the handle waiting, to give
1482 waiting threads a chance to check for bogus states before
1485 * mutexes.c (namedmutex_prewait): Use the prewait stage to check
1486 for named mutexes that have been abandoned in a locked state (eg
1487 if a process exited abnormally while owning the mutex) and
1488 override it if needed.
1490 2006-03-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1492 * wait.c: speed up WaitFor* when the timeout is 0.
1494 2006-03-03 Dick Porter <dick@ximian.com>
1496 * processes.c (ShellExecuteEx): Cope when some of the parameters
1499 2006-02-27 Dick Porter <dick@ximian.com>
1503 * threads.c: Comparing pthread_t with == is not portable, so use
1506 Thu Feb 23 18:47:20 GMT 2006 Paolo Molaro <lupus@ximian.com>
1508 * *.h, *.h: patch from Dick to make Linuxthreads systems work again.
1510 2006-02-22 Dick Porter <dick@ximian.com>
1513 * threads.c: There's no need to use the timed-thread support code
1514 any more, as we aren't using the timed join. This greatly
1515 simplifies thread setup, and fixes a memory leak (bug 77521).
1517 Don't bother to store thread IDs in a hash table, use TLS instead.
1518 The one case that needs to look up the handle of a different
1519 thread (OpenThread()) can do the extra work itself. Fixes bug
1522 * handles.c (_wapi_search_handle): Add a reference when returning
1523 a private handle (shared handles are already reffed.)
1525 2006-02-17 Dick Porter <dick@ximian.com>
1527 * handles-private.h:
1528 * handles.c: Check handle values passed to array lookups. Fixes
1531 2006-02-09 Dick Porter <dick@ximian.com>
1533 * threads.c: Cope with the problems caused by attaching already
1534 existing threads - they don't get the infrastructure to clean up
1535 after themselves, especially the ID to handle hash. This fixes
1538 2006-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1540 * shared.c: use MONO_SHARED_HOSTNAME as a substitute for gethostname()
1541 when creating the shared files in the .wapi directory. Fixes bug #77371.
1543 2006-02-02 Martin Baulig <martin@ximian.com>
1545 * threads.c: Removed the `WITH_INCLUDED_LIBGC' section; it has
1546 never been used so far.
1548 * timed-thread.h (TimedThread): Removed the `stack_ptr' field; it
1549 has only been used by the removed code.
1551 2006-01-03 Neale Ferguson <neale@sinenomine.net>
1553 * atomic.h: Correct s390x definitions and eliminate compiler warnings.
1555 2006-01-03 Sebastien Pouliot <sebastien@ximian.com>
1557 * io.c: Patch _wapi_stat_to_file_attributes against bug #76966, where
1558 sockets could be considered as directory.
1560 2005-12-23 Dick Porter <dick@ximian.com>
1564 * semaphores.c: Implement OpenSemaphore
1567 * mutexes.h: Implement OpenMutex
1573 * event-private.h: Implement named events. Implement OpenEvent.
1575 2005-12-15 Dick Porter <dick@ximian.com>
1577 * processes.c (CreateProcess): The pipe-based cross-process
1578 exclusion technique was trying to write NULL buffers when appname
1579 was NULL (eg when coming from ShellExecuteEx,) which usually
1580 succeeded even though EFAULT was returned - but sometimes it
1581 failed. This meant that the child process could block forever on
1582 the pipe read. Replace it with the simpler shared handle
1583 semaphore protection used everywhere else. This showed up with
1584 the test case in bug 76684.
1586 Tue Dec 13 11:41:49 GMT 2005 Paolo Molaro <lupus@ximian.com>
1588 * shared.c: fallback to private mmap when shared mmap doesn't work
1591 2005-12-06 Dick Porter <dick@ximian.com>
1595 * semaphore-private.h:
1596 * semaphores.c: Implement named semaphores
1598 2005-11-24 Dick Porter <dick@ximian.com>
1600 * processes.c (GetProcessId): Implement GetProcessId()
1602 2005-11-17 Dick Porter <dick@ximian.com>
1605 * processes.c: Implement ShellExecuteEx as a wrapper around
1608 2005-11-11 Dick Porter <dick@ximian.com>
1610 * threads.c: Give mutex abandoning its own exported function, so
1611 it can be called when the runtime is cleaning up.
1613 * handles.c (_wapi_search_handle_namespace): Do a handle
1614 collection befre starting to check namespace strings, so that any
1615 stale cruft gets removed.
1617 2005-11-11 Dick Porter <dick@ximian.com>
1619 * threads.c: Move thread handles back into the shared space.
1621 * handles.c (_wapi_handle_unref): Add support for shared handles
1622 with close() handlers
1624 2005-11-04 Dick Porter <dick@ximian.com>
1626 * sockets.c (ioctlsocket): Use select instead of if to avoid a
1627 type promotion problem on 64bit freebsd. Based on patch by Lou
1628 Kamenov <kamenovl@gmail.com>, fixes bug 76447.
1630 2005-11-04 Dick Porter <dick@ximian.com>
1632 * io.c (file_write): Only do the file locking if
1633 MONO_STRICT_IO_EMULATION is set.
1635 2005-10-21 Dick Porter <dick@ximian.com>
1638 * handles.c (_wapi_lookup_handle): Cope when the shared part of a
1639 handle has been deleted.
1640 (_wapi_handle_unref): And when the deleted shared part is pointed
1641 to as a handle is deleted
1643 2005-10-20 Dick Porter <dick@ximian.com>
1645 * processes.c (process_set_current): If the expected process
1646 handle slot doesn't contain the correct pid, create a new handle.
1648 * handles.c (_wapi_search_handle): When the search doesn't find
1649 anything, return failure instead of the last handle we looked at.
1650 (_wapi_handle_ref, _wapi_handle_unref): Don't try to ref or unref
1651 unused handles (makes tracking refcounting bugs easier.)
1653 2005-10-19 Dick Porter <dick@ximian.com>
1656 * handles-private.h:
1660 * collection.c (_wapi_handle_collect): Remove the shared handle
1661 indirection layer, and use locking instead. Delete other
1662 complexity that is no longer needed. Refcount shared handles and
1663 delete them when needed, but keep the timestamps so that orphaned
1664 handles will be cleaned up eventually.
1666 * shared.c (_wapi_shm_file): Add processor, OS and struct size
1667 info to the shared file names, to cope with dual-boot and 32/64bit
1668 size issues. Fixes bug 75839.
1670 * wait.c (WaitForMultipleObjectsEx): No need to distinguish
1671 between shared handles and private, as the wait functions cope
1672 with both together now.
1674 2005-10-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1676 * io.c: removed NO_SIGPIPE macro.
1677 * sockets.c: no need for MSG_NOSIGNAL or ignoring SIGPIPE.
1679 2005-10-11 Dick Porter <dick@ximian.com>
1681 * sockets.c (_wapi_getsockopt): Translate SO_ERROR results into
1684 * error.c (errno_to_WSA): Don't return a bogus error if someone
1685 asks to translate errno 0.
1687 2005-10-11 Dick Porter <dick@ximian.com>
1689 * handles.c: Fix several race conditions
1691 2005-10-11 Miguel de Icaza <miguel@novell.com>
1693 * io.c: no need to block SIGPIPE anymore, as it is ignored.
1695 2005-10-05 Dick Porter <dick@ximian.com>
1697 * threads.c (_wapi_thread_own_mutex, _wapi_thread_disown_mutex):
1698 Keep a reference to mutexes owned by threads, so they won't be
1699 destroyed prematurely. Fixes dotmsnclient crash.
1701 2005-09-26 Sebastien Pouliot <sebastien@ximian.com>
1703 * io.c: Apply patch from #76192 (Can't write files past 2gb on AMD64
1704 (x86_64)) for Brion on IRC (Dick approved it).
1706 2005-09-23 Dick Porter <dick@ximian.com>
1708 * processes.c: Don't wait for processes that have already been
1709 signalled; also fix typo.
1711 * handles.c: Improve locking inside new handle and handle
1712 searching functions.
1714 2005-09-20 Dick Porter <dick@ximian.com>
1717 * processes.c: Periodically waitpid for known process IDs. Fixes
1720 2005-09-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1723 (CreateFile): if the file is a named pipe, treat the handle as a pipe,
1724 not as a file. Fixes bug #76075.
1726 2005-08-27 Zoltan Varga <vargaz@gmail.com>
1728 * atomic.h: Add support for intel icc.
1730 2005-08-25 Zoltan Varga <vargaz@gmail.com>
1732 * io-layer.h: Include winbase.h not WinBase.h.
1734 2005-08-19 Dick Porter <dick@ximian.com>
1736 * threads.c, threads.h, thread-private.h: Use a gsize to store the
1737 thread ID, so it can hold a 64 bit value if needed.
1739 2005-07-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1741 * error.c: map ENOENT to WSAECONNREFUSED. It might happen when
1742 connecting to unix sockets. Closes bug #75632.
1744 2005-07-05 Dick Porter <dick@ximian.com>
1746 * io.c: Make sure SIGPIPE is ignored when calling write(2).
1747 Prevents the runtime exiting when writing to a closed pipe,
1750 2005-06-30 Dick Porter <dick@ximian.com>
1752 * shared.c (_wapi_shm_semaphores_init): Add some helpful error
1753 messages when semget () fails due to lack of resources.
1755 2005-06-21 Dick Porter <dick@ximian.com>
1760 * threads.c: Keep a list of owned mutexes in each thread handle,
1761 so that it is easier to abandon them when the thread exits.
1762 Removes a bottleneck when multiple threads are finishing in
1765 2005-06-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1767 * io.c: (GetLogicalDrives) when a bogus line is read, don't leak memory.
1768 When the buffer has not enough space, close the file before returning.
1770 2005-06-09 Duncan Mak <duncan@novell.com>
1772 * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to
1773 all public headers. Fixes #74919.
1775 2005-05-30 Zoltan Varga <vargaz@freemail.hu>
1777 * atomic.h: Add IA64 atomic ops.
1779 2005-05-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1781 * processes.c: make ExitCode be valid even if the user didn't call
1782 WaitForExit() and is just polling on HasExited.
1784 2005-05-17 Dick Porter <dick@ximian.com>
1786 * io.c (file_getfilesize): Clear the error value, so that files
1787 with sizes with the low bits 0xFFFFFFFF can be distinguished from
1790 2005-05-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1792 * shared.c: forgot to ignore a warning.
1794 2005-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1796 * shared.c: don't display warnings after reboots.
1798 2005-05-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1800 * sockets.c: on windows, getsockopt/setsockopt for send/receive timeout
1801 use an integer in milliseconds. We were using a struct timeval.
1803 2005-05-06 Dick Porter <dick@ximian.com>
1805 * handles-private.h:
1812 * collection.h: Use SysV semaphores for managing access to the
1813 shared memory - in return for the ludicrous api we get
1814 synchronisation primitives that can be cleaned up by the kernel
1815 even when a process quits unexpectedly. This removes the
1818 2005-05-05 Lluis Sanchez Gual <lluis@novell.com>
1820 * handles.c: Always use polling in the waits, since
1821 mono_cond_timedwait can't be interruped by the thread abort signal.
1823 2005-04-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1825 * events.c: calling Set on AutoResetEvent several times has the same
1826 effect as calling it only once if no thread is waiting for it.
1828 2005-04-29 Dick Porter <dick@ximian.com>
1830 * processes.c (EnumProcesses): Use a GArray instead of a GPtrArray
1831 now it's storing pids not handles, also fixes memory leak caused
1832 by unclear glib documentation.
1834 * sockets.c (WSACleanup): Remove unused variable
1836 2005-04-29 Dick Porter <dick@ximian.com>
1838 * handles.c (_wapi_handle_check_share_by_pid): For systems that
1839 don't have file descriptor info in /proc check that the original
1840 opener of a file is still there, if a share violation would
1843 2005-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1846 * handles-private.h: added _wapi_handle_forecch that loops through all
1847 the handles and call a callback function when a handle of the given
1850 * sockets.c: no need to keep open sockets in an array, as we have them
1851 in the handles structure.
1855 2005-04-28 Dick Porter <dick@ximian.com>
1857 * processes.c: Cope with handles that are only around for as long
1858 as the search is running. If we're searching for process handles,
1859 check to see if the process is still running and signal it if not.
1861 * handles.c (_wapi_search_handle): Search in the shared space as
1862 well. Fixed bug 74752.
1865 * handles.c (_wapi_handle_new_from_offset):
1866 _wapi_handle_new_for_existing_ns () was doing exactly the same as
1867 this, so deleted it.
1869 2005-04-26 Dick Porter <dick@ximian.com>
1871 * handles.c: Fix stupid thinko where if a new shared handle is
1872 created but a collection was needed to free some space, it
1873 returned an error anyway. Should fix the messages shown in bug
1876 2005-04-25 Dick Porter <dick@ximian.com>
1878 * handles.c (_wapi_handle_check_share): Only consider mono
1879 processes when looking to see if a file is still being held open,
1880 while checking share permissions.
1882 2005-04-25 Dick Porter <dick@ximian.com>
1886 * wapi-private.h (struct _WapiHandleOps):
1887 * handles.c (_wapi_handle_unref): When destroying handles, save
1888 the handle data and call the close function only after the array
1889 slot has been cleared. This prevents race conditions with file
1890 descriptors, fixing bug 74713.
1892 * mutexes.c: Delete the handle close functions, they didn't do
1895 * error.c (_wapi_get_win32_file_error): Add a mapping for EINTR so
1896 the "Unknown error" g_warning doesn't get displayed.
1898 2005-04-25 Dick Porter <dick@ximian.com>
1901 * threads.c: Make thread handles process-private for now to take
1902 some of the space pressure off the shared memory, while I work on
1905 2005-04-21 Dick Porter <dick@ximian.com>
1907 * handles.c (_wapi_handle_check_share): Make sure there is a "fd"
1908 dir in /proc before blowing away handle info. Fixes bug 74649.
1910 2005-04-21 Dick Porter <dick@ximian.com>
1912 * wait.c (WaitForMultipleObjectsEx): Implement special waits
1914 * handles.c (_wapi_handle_wait_signal_poll_share): Don't return a
1915 timeout, just wait briefly for the private signals and let the
1916 waiting thread test again. This prevents us missing shared
1919 2005-04-21 Dick Porter <dick@ximian.com>
1921 * collection.h (_WAPI_HANDLE_COLLECTION_EXPIRED_INTERVAL): Reduce
1922 the time before a slot is considered too old and deleted. This is
1923 a workaround while I come up with a proper fix.
1925 2005-04-21 Dick Porter <dick@ximian.com>
1930 * handles.c (_wapi_handle_new): Turn assertions into errors.
1932 * collection.c (_wapi_handle_collect): Use symbols not magic
1933 numbers for timeout values
1935 2005-04-19 Dick Porter <dick@ximian.com>
1939 * handles.c (_wapi_handle_count_signalled_handles)
1940 * handles-private.h (_wapi_handle_shared_lock_handle): Use new
1941 shared handle locks in critical sections.
1943 * handles.c (_wapi_handle_new_for_existing_ns): Reuse old handles
1944 if there is already one there.
1946 * handles.c (_wapi_handle_ref): It was possible for a process to
1947 exit before getting around to updating shared handle timestamps,
1950 Tue Apr 19 16:25:47 CEST 2005 Paolo Molaro <lupus@ximian.com>
1952 * threads.c: fix lookup of the thread id in the has table:
1953 always use the id value, not the pointer to the id.
1955 2005-04-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1957 * handles.c: fix handle returned in _wapi_handle_search_handle. Dick
1960 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1962 * io-layer/sockets.c: FIONBIO with a TRUE argument means we want
1963 non-blocking IO, not the other way around.
1965 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1969 * handles-private.h: GetFileType wasn't checking if we have memory
1970 allocated for the handle before dereferencing it. Fixes a FileStream
1973 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1977 * handles-private.h: we were calling g_renew to expand the handle array,
1978 but that might move the memory and we might have pthread conditions or
1979 mutexes in the original memory area that are being used. Now instead of
1980 expanding an existing array, we just create new ones and keep a list of
1981 them. Access to _wapi_private_handles had to be modified accordingly.
1983 2005-04-15 Dick Porter <dick@ximian.com>
1985 * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN
1987 2005-04-14 Raja R Harinath <rharinath@novell.com>
1989 * wapi-private.h: Remove reference to 'daemon-private.h'.
1991 Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro <lupus@ximian.com>
1993 * atomic.h: applied patch from mass@akuma.org (David Waite)
1994 to fix InterlockedExchangeAdd.
1995 Fixed a few other functions, including InterlockedCompareExchange()
1996 which was miscompiled by gcc with optimizations enabled.
1998 2005-04-13 Dick Porter <dick@ximian.com>
2000 * io.c (share_check):
2001 * handles.c (_wapi_handle_check_share): Refine the file check so
2002 that sharing violations within the same process don't cause
2005 2005-04-13 Dick Porter <dick@ximian.com>
2007 * io.c (FindFirstFile): Fix bugs introduced with the merge (bug
2010 2005-04-12 Dick Porter <dick@ximian.com>
2012 The daemon-less io-layer. Extensive lowlevel changes in
2013 handles.c, requiring some corresponding changes in other files
2014 calling these functions. Private_foo structures have been
2017 File descriptor handling differences account for most of the
2018 changes in io.c and sockets.c.
2022 * mutexes.c: Named mutexes are now a distinct type.
2023 * atomic.h: Fix a PPC uninitialised variable warning.
2024 * wait.c: Check conditions before waiting on a condition variable.
2025 * processes.c: Handle process fork and wait without a daemon
2026 (though this has the limitation of only being able to wait for
2029 2005-04-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2036 * sockets.h: removed dead code that deals with async IO.
2038 2005-03-30 Zoltan Varga <vargaz@freemail.hu>
2040 * atomic.c (InterlockedIncrement): Fix fallback implementation of
2041 InterlockedIncrement and InterlockedDecrement. Fixes #74228.
2043 2005-03-29 Sebastien Pouliot <sebastien@ximian.com>
2045 * io-layer.h: Add required header files for compiling with VS.NET.
2047 2005-03-17 Miguel de Icaza <miguel@novell.com>
2049 * io.c: don't fail on NFS when there are no more locks available.
2051 2005-03-09 Dick Porter <dick@ximian.com>
2053 * error.c (_wapi_get_win32_file_error): ENFILE and EMFILE should
2054 map to ERROR_TOO_MANY_OPEN_FILES, not ERROR_NO_MORE_FILES. Fixes
2057 2005-03-09 Dick Porter <dick@ximian.com>
2059 * daemon.c (process_process_fork): Initialise the handle data
2060 before using it in the error case. This is probably the error
2061 we're working around in the previous change. Spotted by Taru Jain
2062 <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.
2064 2005-03-07 Dick Porter <dick@ximian.com>
2066 * daemon.c: It looks like g_shell_parse_argv() can return
2067 argv[0]=NULL somehow, yet still not give an error. Make sure we
2068 don't pass NULL to strrchr(), working around a segfault that
2069 showed up on ZLM testing.
2071 2005-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2073 * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is
2074 the expected error code showed by the test case in bug #73053.
2076 2005-02-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2078 * io.c: another leftover.
2080 Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>
2082 * io.c: fixed logic in checking errno in rev 40815.
2084 Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>
2086 * threads.c: we don't depend on the GC checking tls
2088 * processes.c: remove unused ref to GC headers.
2090 Thu Feb 17 19:57:11 CET 2005 Paolo Molaro <lupus@ximian.com>
2092 * io.c: remove _wapi_thread_cur_apc_pending () checks
2093 when the siscall should return immediatly and handle
2094 the case when a syscall is interrupted without
2095 erroring out, but returning a 0 read/write if possible.
2096 Still the cases of read from file need to be handled.
2098 Tue Feb 8 18:28:11 CET 2005 Paolo Molaro <lupus@ximian.com>
2100 * threads.c: make people test with 1 MB stack per thread.
2102 2005-01-17 Dick Porter <dick@ximian.com>
2104 * timefuncs.h: Make WapiFileTime endian-aware, as it's often
2105 cast to and from 64bit ints. Fixes bug 71213.
2107 2005-01-11 Dick Porter <dick@ximian.com>
2109 * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
2112 Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>
2114 * atomic.h: Fix functions on s390.
2116 Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>
2118 * atomic.h: fix some functions on ppc (tests/interlocked.cs).
2120 2005-01-10 Dick Porter <dick@ximian.com>
2122 * misc.c (_wapi_calc_timeout): Guard against overflow when
2123 calculating timeouts. This makes waiting with a large
2124 (Int32.MaxValue) timeout not return immediately.
2126 2004-12-23 Ben Maurer <bmaurer@ximian.com>
2128 * io.c (io_ops): make this `const' so it is shareable (well, only
2129 really shareable if it is statically linked...)
2131 Mon Dec 20 11:58:33 CET 2004 Paolo Molaro <lupus@ximian.com>
2133 * threads.c, threads.h: add accessor to get the pthread_key_t for
2136 2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2138 * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS
2139 if it exists and is not the same as 'src'.
2141 2004-12-01 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
2143 * atomic.h : Fix InterlockedCompareExchange for s390/s390x.
2145 2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2147 * processes.c: unquote the cmd path, allow for ' or " when quoting and
2148 pass the quoted program name to the daemon, otherwise the call to
2149 g_shell_unquote in the daemon will break things up.
2151 2004-10-14 Dick Porter <dick@ximian.com>
2153 * sockets.c (_wapi_accept): Revert the previous change. We now
2154 set the accepted socket to have the same blocking status as the
2155 listening socket in managed code. This follows MS behaviour.
2157 2004-10-14 Dick Porter <dick@ximian.com>
2159 * sockets.c (_wapi_accept): On Darwin, make sure a newly
2160 accept()ed socket is blocking. Fixes bug 67355, patch by
2161 grompf@sublimeintervention.com.
2163 2004-10-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2165 * system.c: check the number of online processors instead of the
2166 existing ones. Sanitize return value if it's an error.
2168 2004-10-03 Ben Maurer <bmaurer@ximian.com>
2170 * system.c: Add support for getting the # of cpus.
2172 2004-09-28 Dick Porter <dick@ximian.com>
2174 * io.c (pipe_close_private): Fix one small typo in the last change
2175 that totally hosed process creation with redirected pipes.
2177 2004-09-24 Dick Porter <dick@ximian.com>
2184 * handles-private.h: Cope when a file descriptor is reused while
2185 the handle that thought it owned it is still referenced, instead
2186 of asserting. Probably fixes bug 66479, though we've been unable
2189 2004-09-09 Dick Porter <dick@ximian.com>
2192 * io.c: Set error codes everywhere.
2194 2004-09-06 Dick Porter <dick@ximian.com>
2196 * handles.c (_wapi_handle_unref): Reset the private record's type
2197 (CloseHandle): Check for a fd mapping failure, and return FALSE.
2198 (_wapi_handle_process_fork): Fix long-standing bug in checking
2199 handle return values. Also do the required bookkeeping with the
2200 new process's handles.
2202 * daemon.c: When creating a new process's handles, check whether
2203 the shared space needs to be increased
2205 2004-09-05 Zoltan Varga <vargaz@freemail.hu>
2207 * shared.c (_wapi_shm_file): Fix leaking of filename.
2209 2004-08-19 Dick Porter <dick@ximian.com>
2211 * handles.c (_wapi_handle_count_signalled_handles): Fix thinko
2212 introduced with the fd offset stuff: unlock handles properly when
2213 backing off. Fixes the monologue hang at exit.
2215 2004-08-18 Dick Porter <dick@ximian.com>
2218 * io.c: Check that new fds fit in the table, return error if not
2220 * daemon.c (_wapi_daemon_main):
2221 * handles.c (shared_init): Have all processes agree on a size for
2224 2004-08-17 Dick Porter <dick@ximian.com>
2226 * daemon.c (process_new):
2227 * handles.c (_wapi_handle_new_internal): Cope when the space
2228 reserved for file descriptors is larger than the shared segment
2229 size. Fixes the crash reported when running mono under gdb on
2232 2004-08-16 Dick Porter <dick@ximian.com>
2236 * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
2237 error checking with passed-in file descriptors.
2239 2004-08-11 Dick Porter <dick@ximian.com>
2242 * io.c: Returned handle values are the file descriptor the handle
2246 * handles-private.h:
2247 * daemon.c: Reserve the range of handles that can have the same
2248 values as file descriptors. These won't be used, but the values
2249 will be used as file, console, pipe or socket handles. The fd to
2250 handle mapping is done internally and is invisible to users.
2253 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
2254 reserve a chunk of handle space.
2256 2004-08-04 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
2258 * atomic.h: add support for 64-bit S/390
2260 2004-07-22 Dick Porter <dick@ximian.com>
2263 * threads.c: Move the destruction of the internal thread data to
2264 after the thread has been joined. Fixes bug 61418.
2266 2004-07-14 Dick Porter <dick@ximian.com>
2268 * wait.c (test_and_own): When not waiting for all handles to
2269 become signalled, only own and return the lowest. All the
2270 documentation suggests that the old way was correct, but
2271 experimentation shows it actually works like this. Patch by
2272 Sébastien Robitaille
2273 (sebastien.robitaille@croesus.com), fixes bug 61511.
2275 2004-07-09 Ben Maurer <bmaurer@ximian.com>
2277 * threads.c: register roots for gc
2279 2004-07-08 Dick Porter <dick@ximian.com>
2281 * io.c (file_seek): If there is a high 32bit offset part, make
2282 sure the low part isn't sign-extended. Set error codes when
2283 returning failure. Fixes bug 61131.
2285 2004-07-06 Dick Porter <dick@ximian.com>
2287 * io.c (file_setfiletime): Check for underflow when converting to
2288 time_t values. Set error codes when returning failure. Fixes bug
2291 2004-07-05 Dick Porter <dick@ximian.com>
2293 * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable.
2295 * daemon.c (unref_handle): Only destroy a handle if all processes
2296 have released it, not just the current one. Fixes bug 60887.
2298 2004-06-30 Zoltan Varga <vargaz@freemail.hu>
2300 * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
2301 to prevent warnings.
2303 2004-06-24 Dick Porter <dick@ximian.com>
2305 * mutexes.c: Indicate when a named mutex was reused
2307 2004-06-24 Dick Porter <dick@ximian.com>
2309 * threads.c (SuspendThread):
2310 * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a
2311 while loop. See bug 58161.
2313 Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro <lupus@ximian.com>
2315 * io.c: don't use sharemode for on-disk file permissions: it's used
2316 for shared access to the open file.
2318 2004-06-22 Dick Porter <dick@ximian.com>
2320 * events.c (CreateEvent): When creating an auto-reset event that
2321 is initially owned, make sure the set count starts at 1.
2323 2004-06-18 Dick Porter <dick@ximian.com>
2326 * events.c: Auto-reset events need to release one thread for each
2327 time SetEvent() is called. Fixes bug 41292.
2331 * mutexes.c: Scan for mutexes that are still locked by a thread
2332 when it exits. Fixes the MS demo app linked by bug 41292.
2334 * wait.c (test_and_own): Make sure a handle is signalled before it
2337 2004-06-16 Dick Porter <dick@ximian.com>
2339 * timed-thread.c: Call the thread cleanup exit routine before taking
2340 the join mutex, because this could deadlock if another thread tries
2341 to join in the meantime. This fixes the hang-at-exit problem seen
2344 2004-06-03 Lluis Sanchez Gual <lluis@ximian.com>
2346 * threads.c: Implemented SleepEx.
2347 * threads.h: Fixed SleepEx signature.
2349 2004-06-03 Miguel de Icaza <miguel@ximian.com>
2351 * threads.c: When running under valgrind, do not allocate too much
2352 stack, as Valgrind default is 1 meg.
2354 2004-05-27 Dick Porter <dick@ximian.com>
2357 * io.c: Implemented LockFile() and UnlockFile()
2359 2004-05-21 Dick Porter <dick@ximian.com>
2361 * io.c (CreateFile): Check for existing share modes when opening
2365 * handles-private.h:
2366 * daemon-messages.h:
2367 * daemon.c: Maintain a hash of file share modes, keying on device
2368 and inode (to cope with symlinks.)
2370 2004-05-20 Lluis Sanchez Gual <lluis@ximian.com>
2372 * daemon-messages.c: Retry if the communication with the daemon is
2373 interrupted by a signal.
2374 * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped.
2375 Only return an error in this case if there is something in the apc queue
2376 (which means that it is an interruption requested by the "user").
2377 * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as
2378 true since the wait is small.
2379 * shared.c: Retry write calls when interrumped by a signal.
2380 * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which
2381 returns TRUE if there are pending asynchronous calls (APC) for the
2382 provided thread. Also added _wapi_thread_dispatch_apc_queue which calls
2383 the enqueued APCs. Defined a new struct ApcInfo that holds information
2384 about an enqueued APC.
2385 * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same
2386 as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue.
2387 These last two methods call the corresponding apc methods in
2388 thread-private using the provided thread handle.
2389 * threads.h: Added QueueUserAPC.
2390 * uglify.h: Added WapiApcProc (needed by QueueUserAPC).
2391 * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and
2392 WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support
2393 for APCs in those two methods and also in SleepEx.
2395 2004-05-17 Dick Porter <dick@ximian.com>
2397 * io.c (CopyFile): Speed up. Fixes bug 57859.
2399 2004-05-13 Dick Porter <dick@ximian.com>
2400 * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current
2401 thread doesn't own the mutex, rather than assert()ing.
2403 2004-05-11 Dick Porter <dick@ximian.com>
2405 * shared.c (_wapi_shm_attach): Cope when a previous daemon startup
2406 attempt failed, leaving shared files that look like a daemon is
2409 2004-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2412 (SetFileAttributes): don't the the exec bit if the corresponding read
2415 2004-05-10 Zoltan Varga <vargaz@freemail.hu>
2417 * io.c (FindFirstFile): Fix invalid free.
2419 2004-05-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2421 * io.c: translate from GFileError to errno codes and don't free
2422 variables right after calling mono_io_scandir, as we may overwrite
2425 2004-05-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2427 * io.c: g_dir_open return ENOENT for directories on which we don't have
2428 read/execute permission, while returning EPERM for anything below those.
2429 So, change ENOENT by EPERM if the directory exists.
2431 2004-05-07 Dick Porter <dick@ximian.com>
2433 * io.c (SetFileAttributes): Don't have failed chmod()s cause a
2434 "file not found" error. Fixes bug 54032.
2436 2004-05-07 Dick Porter <dick@ximian.com>
2438 * io.c (FindFirstFile): Comment out a windows-compatibility check
2439 that breaks when directories have metachars in their names.
2440 Workaround for bug 58116.
2442 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2444 * io.c: fixed for FindFirstFile for empty directories. Closes
2447 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2449 * processes.c: set the start time for the current process. Fixes bug
2452 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2454 * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
2455 * io.c: implemented scandir using glib functions.
2457 2004-05-04 Dick Porter <dick@ximian.com>
2459 * daemon.c (read_message): Return FALSE on error so the GSource
2460 callback itself can return FALSE. Cures the infinite loop poll()
2462 * shared.c: Fix some daemon startup race conditions.
2464 2004-04-29 Miguel de Icaza <miguel@ximian.com>
2466 * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k,
2467 use the stack, do not use dynamic memory.
2469 2004-04-29 Zoltan Varga <vargaz@freemail.hu>
2471 * io.c: Add scandir implementation for platforms which do not have
2474 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2476 * io.[ch]: implemented GetLogicalDriveStrings.
2478 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2481 * sockets.c: use the field name from configure when accessing sigval
2482 pointer field. Makes this work on the Mac.
2484 2004-04-28 Bernie Solomon <bernard@ugsolutions.com>
2486 * atomic.c: (InterlockedExchange) fix typo for
2489 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2492 * sockets.c: added check for sys/aio.h.
2494 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2496 * error.[ch]: added _wapi_get_win32_file_error...
2497 * io.c: ... which was _wapi_get_win32_error here.
2498 * sockets.c: rename the function calls here too.
2500 2004-04-28 Dick Porter <dick@ximian.com>
2502 * daemon-messages.c: Avoid a deadlock when a thread is killed while
2503 waiting for the daemon by using a recursive mutex. Helps bug 56699.
2505 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2507 * io.c: fixed leak in async_notifier().
2509 * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl
2512 * threads.c: removed old comment.
2514 2004-04-26 David Waite <mass@akuma.org>
2516 * daemon-messages.h:
2523 * wapi-private.h: remove comma from end of enumeration declarations
2524 * status.h: cast unsigned int types to int for enum assignment
2526 2004-04-26 David Waite <mass@akuma.org>
2529 * timefuncs.c: declare 64-bit constants as long long types (i.e.
2532 2004-04-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2534 * socket-wrappers.h: _wapi_socket == WSASocket now. Added
2535 WSA_FLAG_OVERLAPPED.
2537 * sockets.c: new unused parameters for _wapi_socket.
2539 2004-04-22 Miguel de Icaza <miguel@ximian.com>
2541 * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle
2542 the fact that MacOS X is a piece of junk (sem_init is *defined* in
2543 the libc, but they return `not implemented').
2545 2004-04-22 Dick Porter <dick@ximian.com>
2548 * handles-private.h: Reference the handle when it is locked, so
2549 that another thread can't blow it away while we're waiting for it
2550 to become signalled.
2561 * handles-private.h:
2564 * daemon-messages.c:
2565 * critical-sections.c:
2566 * atomic.c: Added pthreads cleanup handlers and error asserts
2569 * handles.c: Fixed the gcc "variable might be used uninitialised"
2570 warnings. They can't happen, but gcc doesn't know that
2571 g_assert()s don't return.
2573 Fixed the declaration of _wapi_handle_process_kill() so that it
2574 expects the correct type for the pid.
2576 * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that
2577 hasn't been used in ages and just made the code more complex.
2579 2004-04-17 Zoltan Varga <vargaz@freemail.hu>
2581 * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
2582 warnings. Fixes #57168.
2584 2004-04-16 Dick Porter <dick@ximian.com>
2586 * threads.c (Sleep): Using div(3) with a negative (when signed)
2587 numerator causes the quotient to be 0 and the remainder to be the
2588 numerator. This feeds a small negative value to nanosleep(3),
2589 which will return immediately and cause a busy wait. Fixes bug
2592 2004-04-15 Dick Porter <dick@ximian.com>
2595 * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3)
2596 and fnmatch(3) instead of glob(3). glob() can't cope with being
2597 given filenames containing metachars. This fixes bug 40557.
2599 2004-04-14 Bernie Solomon <bernard@ugsolutions.com>
2601 * security.c: #warning is a GCC-ism
2603 2004-04-13 Sebastien Pouliot <sebastien@ximian.com>
2605 * security.c: Removed GetUserName as glib g_get_user_name does a
2606 better (portability) job. Added ImpersonateLoggedOnUser and
2609 2004-04-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2611 * mono-mutex.h: move pthread_mutex_timedlock declaration to...
2612 * mono-mutex.c: ...here. It was causing a warning that prevented
2613 libgdiplus compilation.
2615 2004-04-04 Miguel de Icaza <miguel@ximian.com>
2617 * security.c (GetUserName): Make it work on MacOS X
2619 2004-04-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2621 * security.c: use getpwuid_r if available. This one is thread-safe.
2623 2004-04-02 Sebastien Pouliot <sebastien@ximian.com>
2625 * Makefile.am: Added security.c|h.
2626 * security.c: New file for security related functions. Added function
2627 GetUserName to fix #56144.
2628 * security.h: New. Header file for security.c
2629 * wapi.h: Added include for security.h
2631 2004-03-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2633 * daemon-messages.h: added kill structs.
2635 * daemon.c: implemented process_process_kill.
2636 * handles-private.h: define process_process_kill.
2637 * handles.c: implemented _wapi_handle_process_kill.
2638 * processes.[ch]: implemented TerminateProcess.
2640 2004-03-25 Bernie Solomon <bernard@ugsolutions.com>
2642 * daemon.c (rem_fd): On solaris you seem to get an
2643 error even after removing the input source so don't
2644 try and rem_fd it twice.
2646 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
2648 * daemon.c: in process_post_mortem, If the child terminated due to the
2649 receipt of a signal, the exit status must be based on WTERMSIG, since
2650 WEXITSTATUS returns 0 in this case.
2652 2004-03-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2654 * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.
2656 2004-03-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2658 * daemon.c: only call getdtablesize () once.
2659 * processes.c: wait 500 ms to check if execve failed and throw the same
2660 exception as MS on failure. Fixes bug #32809.
2662 2004-03-17 Bernie Solomon <bernard@ugsolutions.com>
2664 * io.c (async_notifier): use "union sigval" rather
2665 than sigval_t as Solaris doesn't have sigval_t
2666 (which isn't in IEEE 1003.1 either).
2668 2004-03-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2670 * io.c: added debug stuff and removed a few redundant lines in
2673 2004-03-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2675 * io-private.h: added new fields for file structure. Declare
2676 _wapi_io_add_callback.
2678 * io.c: added _wapi_get_win32_error, support aio_read/write in
2679 file_read/write. Implemented _wapi_io_add_callback, which is where
2682 * io.h: added new fields for WapiOverlapped and typedef for the
2685 * processes.c: fixed off-by-one bug when handling environment variables
2688 * threads.[ch]: implemented BindIoCompletionCallback.
2690 * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE.
2692 2004-03-14 Zoltan Varga <vargaz@freemail.hu>
2694 * socket-wrappers.h: Remove extra semicolon.
2696 2004-03-03 Dave Camp <dave@ximian.com>
2698 * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
2699 Use a new main context.
2701 2004-03-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2704 (GetFileAttributes): set the error depending on errno instead of
2705 setting ERROR_FILE_NOT_FOUND always. See bug #55160.
2707 2004-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2710 (CopyFile): free the buffer on error.
2712 (WSAIoctl): free the buffer on error.
2714 2004-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2716 * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT.
2718 * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW
2719 using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style.
2721 2004-01-27 Bernie Solomon <bernard@ugsolutions.com>
2723 * shared.c (_wapi_shm_file): add hostname
2724 to shared data file names to handle NFS mounted
2727 Mon Jan 26 16:15:03 CET 2004 Paolo Molaro <lupus@ximian.com>
2729 * sockets.h: remove obsolete soklen_t typedef.
2731 Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>
2733 * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket
2734 wrappers to its own non-installed header file.
2736 2004-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2739 (FindFirstFile): unlock the handle if FindNextFile fails.
2740 (FindNextFile): g_free a couple of pointers before retrying.
2743 (WaitForMultipleObjects): if only one handle provided, use
2744 WaitForSingleObject.
2746 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2748 * handles-private.h: (_wapi_handle_type) check
2749 for segment in range before using it
2751 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
2753 * thread-private.h: _wapi_thread_ops is now const
2756 Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>
2758 * threads.c, timed-thread.c, timed-thread.h: use mach
2759 semaphores on Darwin (MacOSX) since the posix ones
2760 are mostly broken there (threads are not created suspended
2761 and they can start executing before they are fully initialized
2762 like in tests/thread-static.cs).
2764 Mon Dec 22 17:18:45 CET 2003 Paolo Molaro <lupus@ximian.com>
2766 * atomic.h: ppc fixes.
2768 2003-12-19 Bernie Solomon <bernard@ugsolutions.com>
2770 * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
2773 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2775 * shared.c: (_wapi_shm_open) make scratch file
2776 not have to immediately regrow to avoid remaps
2777 (HPUX can't cope with these).
2778 (_wapi_shm_attach) use actual size of file
2779 to set scratch data_len for the creating process.
2781 * handles.c: (_wapi_handle_new_internal) make
2782 sure mutex & cond var are initialized even for
2783 non process shared ones.
2784 (_wapi_handle_unref) always call destroy
2785 routines on mutex & cond var
2787 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
2789 * daemon.c: change channel data structure so
2790 input sources are removed from glib event loop
2791 properly. xsp works better on Solaris and
2794 2003-12-12 Bernie Solomon <bernard@ugsolutions.com>
2796 * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
2797 definition with file & line number for non-GCC
2800 2003-12-08 Bernie Solomon <bernard@ugsolutions.com>
2802 * Makefile.am: make sure hppa_atomic.s is in distribution
2804 2003-12-01 Dick Porter <dick@ximian.com>
2807 * mutexes.c (CreateMutex):
2808 * mutex-private.h (struct _WapiHandle_mutex):
2809 * handles.c: Look up certain handle types by name, in a shared
2810 namespace. Currently only mutex handles have this implemented.
2813 * semaphores.c (CreateSemaphore):
2814 * events.c (CreateEvent): Fix signature
2816 2003-11-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2818 * io.c: don't call g_free before testing errno as it may modify it.
2819 If the path exists, return an error if it's not a directory. Fixes
2822 2003-11-20 Dick Porter <dick@ximian.com>
2824 * io.c: Missed a little-endian UTF16 conversion. Patch from
2825 Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.
2827 2003-10-29 Dick Porter <dick@ximian.com>
2829 * io.c (MoveFile): If the move crosses filesystems, try and fall
2830 back to copy and delete. Patch from Jörg Rosenkranz
2831 (JoergR@voelcker.com), fixes bug 50298.
2833 2003-10-28 Dick Porter <dick@ximian.com>
2835 * io.c: Use the new encoding conversion to cope with non-utf8
2836 locales in filenames.
2838 * processes.c: Ditto for process arguments.
2840 Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro <lupus@ximian.com>
2842 * atomic.h: some ppc inline asm fixes (incorrect use of labels,
2843 incorrect register constraints, incorrect clobber lists).
2845 2003-10-13 Bernie Solomon <bernard@ugsolutions.com>
2847 * Makefile.am hppa_atomic.s: add HP 64bit
2848 implementation of atomic ops
2850 2003-10-13 Zoltan Varga <vargaz@freemail.hu>
2852 * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
2853 a conditional for platforms that don't have it.
2855 2003-10-09 Bernie Solomon <bernard@ugsolutions.com>
2857 * threads.c: (CreateThread) use stacksize argument
2858 if non-zero - change default for 64 bits to 4Mb
2860 2003-09-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2862 * sockets.c: set last error when socket creation fails. This shed some
2863 light on bug #49015.
2865 2003-09-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2867 * processes.c: fixed bug #48973: we only change \ by / for the argument
2868 to be used as command.
2869 When getting the program name from the args, don't let the space between
2872 2003-09-24 Bernie Solomon <bernard@ugsolutions.com>
2874 * atomic.h atomic.c: fix sparc so lock is
2875 global, increment does so and it compiles under Sun compiler.
2877 2003-09-22 Bernie Solomon <bernard@ugsolutions.com>
2879 * handles.c: include <string.h> directly as may
2880 not be nested in <sys/un.h> like Linux
2882 2003-09-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2885 (DeleteFile): call SetLastError on failure. Fix by
2886 richard.torkar@htu.se (Richard Torkar). Closes bug #48222.
2888 2003-09-15 Lluis Sanchez Gual <lluis@ximian.com>
2890 * daemon.c: In compare_process(), discard handles already signalled.
2892 2003-09-02 Dick Porter <dick@ximian.com>
2894 * io.c: Work around glib brain-dead assumptions about utf8-encoded
2895 filenames. Fixes bug 30781.
2897 2003-08-28 Dick Porter <dick@ximian.com>
2899 * critical-sections.c: Patch from Bernie Solomon
2900 <bernard@ugsolutions.com> to emit a warning if locking a critical
2903 2003-07-23 Dick Porter <dick@ximian.com>
2906 * daemon.c (maybe_exit): Avoid the race condition when the daemon is
2907 closing but another client comes along when the shared data is still
2908 visible. Should fix bugs 33671 and 35213.
2910 2003-07-23 Dick Porter <dick@ximian.com>
2912 * handles.c: Initialise handle mutex and cond. Fix by
2913 Bernie Solomon <bernard@ugsolutions.com>
2915 2003-07-15 Dick Porter <dick@ximian.com>
2917 * timed-thread.c (timed_thread_start_routine): Fix virtual memory
2918 leak when threads quit. Fixes bug 44067.
2920 Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro <lupus@ximian.com>
2922 * io.c: never add write permission for group or others in
2923 SetFileAttributes ().
2925 2003-06-17 Dick Porter <dick@ximian.com>
2927 * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
2928 ignore the unsupported ones ("fixes" bug 44977).
2930 2003-06-17 Lluis Sanchez Gual <lluis@ximian.com>
2932 * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for
2933 high ms values (there was an overflow).
2935 2003-06-17 Zoltan Varga <vargaz@freemail.hu>
2937 * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.
2939 2003-06-11 Dick Porter <dick@ximian.com>
2941 * shared.c: Fix shared directory creation. Patch from
2942 Pablo Baena <pbaena@uol.com.ar>
2944 2003-06-10 Dick Porter <dick@ximian.com>
2946 * atomic.c: Delete the useless compile warning
2948 2003-06-09 Dick Porter <dick@ximian.com>
2950 * daemon.c: Lookup env as a string array. Fixes bug 44289. Also
2951 make setting the process handle value in the environment actually
2954 * processes.c: Pretty up the process name, if it happens to be
2955 "mono" such as when another mono process forks "mono foo.exe"
2957 2003-06-05 Dick Porter <dick@ximian.com>
2959 * processes.c (process_set_current): Don't do an expensive handle
2960 search at application startup, check the environment to see if the
2961 process handle has already been created.
2963 * io.c: Don't do an expensive handle search when creating stdin,
2964 stdout and stderr handles, just create them all the first time one
2971 * handles-private.h:
2972 * daemon-messages.h:
2974 * daemon.c: Support for "unlimited" number of handles and scratch
2977 Speed up application startup by passing process handle in the
2978 environment, rather than let the app scan all handles (which gets
2979 really slow when there are more than a few thousand to check.)
2981 Initialise some structs passed to syscalls, noticed by valgrind.
2984 2003-05-20 Dick Porter <dick@ximian.com>
2986 * io.c (FindFirstFile): Include . files in the glob. Fixes bug
2989 2003-05-19 Dick Porter <dick@ximian.com>
2991 * threads.c: Set the new thread's stack size to 2M. Fix needed
2992 for BSD, reported by Martin Dvorak <md@9ll.cz>
2994 2003-05-16 Dick Porter <dick@ximian.com>
2997 * io.c: Implement GetTempPath()
2999 2003-05-16 Dick Porter <dick@ximian.com>
3001 * processes.c (CreateProcess): Set some error codes
3003 2003-05-12 Dick Porter <dick@ximian.com>
3005 * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
3006 Patch from Martin Dvorak <mdvorak@ninell.cz>.
3008 2003-05-10 Dick Porter <dick@ximian.com>
3010 * io.c (CopyFile): Copy file mode as well as file data. Based on
3011 suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
3014 2003-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3016 * handles.c: don't call GC_gcollect when creating new handles.
3018 2003-05-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3020 * handles.c: added some debugging code. Call GC_gcollect
3021 before creating a new handle. It makes Lupus' test run smoother and
3022 faster (from 62 to 83 request per second). Notice that calling
3023 GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does
3024 not improve nor degrade the performance, so i don't do it.
3026 2003-05-02 Dick Porter <dick@ximian.com>
3028 * sockets.c: Rearrange closesocket() and socket_close_private(),
3029 and remember to unref the handle, so we don't leak socket handles.
3030 Fix from Pelle Johnsen <pelle.johnsen@mail.dk>
3032 2003-04-11 Dick Porter <dick@ximian.com>
3034 * atomic.h: ARM atomic operations by Malte Hildingson
3035 <tds00mahi@tellus.thn.htu.se>
3037 Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>
3039 * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.
3041 2003-04-03 Martin Baulig <martin@ximian.com>
3043 The following change is conditional to `WITH_INCLUDED_LIBGC'
3044 which is not yet enabled by default.
3046 * threads.c (SuspendThread, ResumeThread): Fully implemented this.
3047 (gc_init): New static function; install a signal handler for
3048 SIGPWR which is used to suspend threads. [FIXME: it SIGPWR
3049 doesn't exist on all Unix systems, we need to find another
3051 (mono_wapi_push_thread_stack): New public function. Tells the
3052 garbage collector about the current stack pointer of a suspended
3055 2003-04-03 Martin Baulig <martin@ximian.com>
3057 * timed-thread.h (TimedThread): Added `suspended_sem',
3058 `suspend_count' and `stack_ptr'.
3060 2003-03-28 Dick Porter <dick@ximian.com>
3062 * atomic.h: PPC support gratiously donated to the public domain
3063 by John Duncan <jddst19@mac.com>
3065 2003-03-20 Dick Porter <dick@ximian.com>
3067 * sockets.c (_wapi_connect): If connect() fails with EACCES, try
3068 setting SO_BROADCAST and connecting again. Fixes bug 39178.
3070 2003-03-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3072 * processes.c: included Jerome Laban's patch and call SetLastError when
3073 the executable is not found.
3075 2003-03-03 Dick Porter <dick@ximian.com>
3077 * io.c (CreateFile): Try opening directories readonly, so that
3078 timestamps can be adjusted. Patch by Elan Feingold
3079 <efeingold@mn.rr.com>.
3081 2003-02-25 Dick Porter <dick@ximian.com>
3083 * shared.c (_wapi_shm_attach): Return a failure code on system
3084 call errors, rather than exiting.
3086 2003-02-21 Dick Porter <dick@ximian.com>
3088 * processes.c (GetCurrentProcessId): Use the current process
3089 handle to return the process ID, as getpid() is unreliable
3090 (linuxthreads gives each thread a different pid). Fixes bug
3093 2003-02-21 Dick Porter <dick@ximian.com>
3095 * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug
3098 2003-02-11 Dick Porter <dick@ximian.com>
3101 * timefuncs.c: Added GetTickCount()
3103 2003-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3105 * error.c: added WSA_EHOSTUNREACH mapping.
3107 2003-01-26 Miguel de Icaza <miguel@ximian.com>
3109 * io.c (SetFileAttributes): This routine is not currently
3110 implemented for the general case, but I added a special case to
3111 set the executable bit on Linux.
3113 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
3115 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
3117 2003-01-08 Dick Porter <dick@ximian.com>
3119 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
3121 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
3123 * daemon.c, handles-private.h, handles.c, wapi-private.h:
3124 Check for an implementation which says it supports
3125 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
3126 defines the symbol. Defined but with a value of -1 still
3127 means that it is unsupported.
3129 2002-12-08 Martin Baulig <martin@ximian.com>
3131 * handles.c (_wapi_handle_new): Create new non-shared handles with
3132 an initial refcount of 1, not 0.
3134 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
3136 * threads.c (TlsGetValue): removed unnecessary mutex
3138 2002-11-20 Dick Porter <dick@ximian.com>
3140 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
3141 need to store their data structure too.
3143 * threads.c: Make sure the threading data is initialised wherever
3146 2002-11-15 Dick Porter <dick@ximian.com>
3148 * timed-thread.c: Removed unneeded parameters in
3149 _wapi_timed_thread_attach().
3151 * threads.c: Renamed AttachThread() to make it not look like
3152 external API. Removed unneeded parameters.
3154 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3156 * error.[ch]: added errno_to_WSA (). It displays a warning and return
3157 WSASYSCALLFAILURE if there is no error mapping for the given errno,
3159 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
3161 2002-10-31 Dick Porter <dick@ximian.com>
3164 * io.c: Define and use INVALID_FILE_ATTRIBUTES
3166 2002-10-07 Dick Porter <dick@ximian.com>
3169 * daemon.c: Use a more accurate time source for process start and
3172 2002-10-03 Dick Porter <dick@ximian.com>
3176 * threads.c: Fixes for freebsd. Make sure that mutex and condition
3177 creation and deletion happen in the process that owns them, when
3178 POSIX shared thread objects aren't supported. This breaks on
3179 freebsd, as pthread_t is a pointer to data.
3181 2002-10-02 Dick Porter <dick@ximian.com>
3183 * shared.c: Use mmap() instead of sysv shm for the shared data.
3185 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
3189 * daemon.c: mmap()ed regions survive fork, so just pass the
3190 pointer to _wapi_daemon_main instead of mapping it again.
3192 2002-10-01 Dick Porter <dick@ximian.com>
3194 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
3195 Unfortunately libgc uses the same thread suspend technique that I
3196 want to, and the two don't mix: libgc will deadlock when it tries
3197 to stop the world if a thread has already been suspended by
3198 someone else. Just do the simple suspended create rather than the
3199 general purpose thread suspension for now.
3201 * threads.c: Pass create flags to the timed_thread create call, to
3202 implement suspended thread creation. ResumeThread() partially
3203 implemented, to cope with the case where a newly created but
3204 suspended thread is launched.
3206 2002-09-30 Dick Porter <dick@ximian.com>
3208 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
3211 2002-09-27 Dick Porter <dick@ximian.com>
3213 * semaphores.c: Only include semaphore.h if it's present. Patch
3214 for BSD from jmmv@hispabsd.org (Julio Merino).
3216 2002-09-27 Dick Porter <dick@ximian.com>
3218 * processes.c: Pass environment and working directory to the
3219 daemon when forking. Don't let argv[0] be duplicated when looking
3220 for the program name. Implement EnumProcessModules (simple
3221 version for now, lsof-style later if needed), GetModuleBaseName,
3222 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
3223 aren't available on Linux).
3225 * process-private.h: Store the process name, and the working set
3229 * handles-private.h: New functions to store and retrieve an array
3230 of strings in the scratch space
3232 * daemon.c: Don't miss deleting some handles when a client exits
3233 (we used to rely on the client doing the final cleanup, but
3234 obviously if the client is no longer there the daemon has to do
3237 Process forking now sets the environment and the working
3240 * io.c: Don't confuse fd 0 with an unassigned handle struct
3242 * atomic.h: Add a google cache alternative to the msdn URL
3244 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3247 (_wapi_recvfrom): added ECONNRESET to the switch.
3249 2002-09-24 Mark Crichton <crichton@gimp.org>
3251 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
3254 2002-09-19 Mark Crichton <crichton@gimp.org>
3256 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
3257 dont have Linux's abstract filesystem for sockets.
3259 2002-09-19 Mark Crichton <crichton@gimp.org>
3261 * atomic.h: Added SPARC atomic asm code.
3262 * daemon.c, handles-private.h, handles.c, wapi-private.h:
3263 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
3264 Solaris 9, however, the code paths don't seem to work. More testing
3265 on the shared case is *really* needed.
3267 2002-09-03 Dick Porter <dick@ximian.com>
3270 * threads.c: Removed PosixKillThread(), because it's not in the
3273 2002-08-20 Dick Porter <dick@ximian.com>
3275 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
3276 multiples of 4 bytes, to keep header structures aligned. Needed
3277 for sparc, at least. (Patch from crichton@gimp.org)
3279 * handles.c: Removed 'disable_shm' variable (we've defaulted to
3280 building with shm enabled for months now)
3282 2002-08-19 Dick Porter <dick@ximian.com>
3284 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
3285 for legacy NeXT-based systems.
3287 2002-08-12 Dick Porter <dick@ximian.com>
3289 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
3290 from Joseph Wenninger <kde@jowenn.at>)
3292 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
3294 * threads.c: use fast spinlocks by default
3296 2002-08-02 Dick Porter <dick@ximian.com>
3298 * io.c (GetStdHandle): Add a handle reference when returning a
3299 duplicate console handle. This fixes the unref_handle errors in
3302 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
3304 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
3307 2002-08-01 Dick Porter <dick@ximian.com>
3309 * threads.c: Use atomic spinlocks in TLS functions
3312 * Makefile.am: Added mono-spinlock.h
3314 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
3316 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
3317 these are needed for sendmsg() and also for struct msghdr (at
3318 least on Solaris). Solaris still won't build because struct msghdr
3319 doesn't have msg_flags, msg_control, or msg_controllen members.
3320 (CMSG_SPACE): Define for systems that don't have it.
3323 2002-07-20 Dick Porter <dick@ximian.com>
3329 * handles.c: Implemented pipe handles
3332 * daemon.c: Fixed bug in handle closing.
3335 * daemon.c: Forked processes now close all open file descriptors.
3337 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
3339 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
3342 2002-07-19 Martin Baulig <martin@gnome.org>
3344 * threads.c (ExitThread): Call exit() if no threads has been
3347 2002-07-17 Dick Porter <dick@ximian.com>
3349 * daemon-messages.c: Freebsd fixes from Andreas Kohn
3350 <andreas.kohn@gmx.net>
3352 2002-07-15 Dick Porter <dick@ximian.com>
3354 * io.c: Removed bogus console_flush() method, that was just cut
3355 and pasted from file_flush when I separated the two handle types.
3357 2002-07-12 Dick Porter <dick@ximian.com>
3359 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
3360 flags. Fixes bug 27633.
3362 2002-07-12 Dick Porter <dick@ximian.com>
3366 * daemon.c: Use size of sockaddr_un.sun_path from config.h
3368 2002-07-12 Dick Porter <dick@ximian.com>
3370 * processes.c (CreateProcess): Send stdin, stdout and stderr
3371 handles if the startup info doesnt specify new ones
3373 * io.c (GetStdHandle): Return the same handle when the same
3374 standard handle is requested
3376 * handles.c: Pass file descriptors when forking
3378 * daemon.c: Use supplied file descriptors when forking a new
3381 * daemon-messages.h:
3382 * daemon-messages.c: Pass stdin, stdout and stderr file
3383 descriptors to the daemon (used when forking)
3385 2002-07-11 Miguel de Icaza <miguel@ximian.com>
3387 * daemon.c (_wapi_daemon_main): Use sizeof
3388 (main_socket_address.sun_path) instead of hardcoded 108 value.
3390 * handles.c (shared_init): Use sizeof
3391 (shared_socket_address.sun_path) instead of hardcoded 108 value.
3393 2002-07-10 Dennis Haney <davh@davh.dk>
3397 * daemon.c: Lots of documentation, some added error checking, and
3398 code readability improvements.
3400 * daemon-messages.h: Add the Error request type to improve error
3403 * daemon-messages.c: Do a bit more error checking on send() and
3404 recv(), and log errors with a higher severity level.
3406 2002-07-04 Dick Porter <dick@ximian.com>
3408 * daemon.c (process_process_fork): Fix argument handling, due to
3409 buggy understanding of g_strsplit() behaviour.
3411 2002-07-03 Dick Porter <dick@ximian.com>
3414 * threads.c: Implement OpenThread(). Define access-control values
3420 * Makefile.am: Added access.h, to hold shared access-control
3423 2002-07-02 Dick Porter <dick@ximian.com>
3425 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
3427 2002-07-02 Dick Porter <dick@ximian.com>
3429 * handles.c (shared_init): Make a second attempt to contact the
3430 daemon if the shared memory attach succeeds, but the connect()
3431 fails. (This copes with the daemon crashing without cleaning up
3437 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
3438 the daemon, it's now built into the library.
3440 2002-06-25 Dick Porter <dick@ximian.com>
3443 * handles-private.h:
3444 * daemon-messages.h:
3445 * daemon.c: Process forking and handle data management
3448 * process-private.h:
3449 * processes.c: Process forking and other support functions
3451 2002-06-25 Dick Porter <dick@ximian.com>
3453 * versioninfo.h: PE resource decoding
3455 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
3456 to be told the string length
3458 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
3459 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
3462 2002-06-12 Dick Porter <dick@ximian.com>
3465 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
3466 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
3467 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
3469 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
3471 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
3472 when writing to a closed socket.
3474 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
3476 * mono-mutex.c (mono_once): New convenience function for my
3481 * critical-sections.c:
3489 * atomic.c: Use mono_once() rather than pthread_once().
3491 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
3493 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
3494 if multiple threads all try to call _wapi_handle_new() before the
3495 shared data has been initialized, it is possible that we could get
3496 into a condition where shared_init() is being executed and later
3497 threads will pass by pthread_once() due to the fact that it has
3498 already been called and so therefor will attempt to use the shared
3499 data before it has been completely initialized. If we instead use
3500 a standard mutex locking mechanism around shared_init(), we can
3501 avoid the situation entirely. By wrapping the mutex locking in a
3502 check to see if we've already initialized the data, we can even
3503 avoid wasting resources by having to lock/unlock the mutex in any
3504 later calls (the only time we'd have to worry about
3505 locking/unlocking is the initial race to call shared_init() at
3508 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
3510 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
3512 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
3514 * daemon.c, handles.c: rename "sun" local var since it's apparently
3515 a #define on Solaris.
3517 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
3519 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
3522 2002-05-15 Dick Porter <dick@ximian.com>
3524 * wait.c: Fix a deadlock in WaitForMultipleObjects
3526 2002-05-14 Dick Porter <dick@ximian.com>
3528 * io.c: Fix a cut&paste error, found by
3529 Jaroslaw Kowalski <jarek@atm.com.pl>
3531 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
3535 2002-05-09 Dick Porter <dick@ximian.com>
3541 * handles-private.h:
3543 * Makefile.am: Remove now-unused file wait-private.h
3545 2002-05-08 Dick Porter <dick@ximian.com>
3547 * shared.c: Better error messages, and report when daemon
3548 connection fails rather than blocking forever. Do some more
3549 shared memory sanity checking.
3551 * handles.c: Better error messages when connecting to shared
3552 memory and the handle daemon. Fall back to non-shared handles if
3553 an error occurs. Set the default back to 'shared handles'. Fix a
3554 crashing bug in scratch space allocation that mangled the block
3557 2002-05-07 Miguel de Icaza <miguel@ximian.com>
3559 * handles.c (shared_init): Disable SHM for now, people have too
3560 many problems with this, and the diagnostics are not helping.
3562 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
3564 * io.c: CreateFile sets win32 last error.
3566 2002-05-05 Dick Porter <dick@ximian.com>
3569 * handles-private.h:
3575 * process-private.h:
3577 * semaphore-private.h:
3581 * event-private.h: Simplify the WapiHandleOps struct: take out all
3582 the file-specific entries, leaving just the items that operate on
3583 handles themselves. Split the close operation into shared and
3584 private parts: shared close is called by the daemon.
3586 * handles.c: As above, but also pass handle allocation, ref and
3587 unref operations to the daemon. Populate the handle_ops array at
3588 compile time, because the daemon needs to call ops on handles too.
3589 Don't bother to track open handle counts any more, the daemon does
3593 * thread-private.h: As above, but also make the thread data
3596 * shared.c: Fork a handle daemon if the calling process created
3597 the shared memory segment.
3600 * daemon-messages.c:
3601 * daemon-messages.h:
3602 * Makefile.am: Build a daemon to manage handle allocation and
3603 destruction without needing to lock the shared memory
3605 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
3607 * atomic.c: Changed to use a normal mutex rather than a spinlock
3608 since a lot of platforms seem to not have them :\
3610 2002-04-30 Dick Porter <dick@ximian.com>
3612 * Completely rewrote the handle waiting code: removed the helper
3613 thread and its attendant complexity. All handle waiting is now
3614 abstracted into the WaitForSingleObject() and
3615 WaitForMultipleObjects() functions.
3617 * Implemented inter-process sharing of handles using sysv shared
3618 memory. This makes handles even more opaque, with a handle now
3619 just an index into an array.
3621 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
3623 * io.c: unitialized pointer in GetCurrentDirectory.
3625 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
3627 * threads.c: destroy the mutex at thread destruction
3628 (if/when thread destruction code will be actually called).
3629 When protecting a tls data pointer from the gc, use also the
3630 thread id in the key.
3632 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
3634 * timed-thread.c: avoid race condition when setting the thread to
3637 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3639 * jit.h: to more #include lines to avoid breaking compilation
3640 under windows when upgrading mingw and w32api to version
3643 2002-04-16 Dick Porter <dick@ximian.com>
3645 * atomic.h: Explanatory comment about lack of 80386 support
3647 2002-04-15 Dick Porter <dick@ximian.com>
3649 * atomic.h: use xaddl for InterlockedIncrement() and
3650 InterlockedDecrement(). Use cmpxchgl in a loop for
3651 InterlockedExchange() and InterlockedExchangePointer().
3653 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
3655 * unicode.c: fix unicode_len() to not access uninitialized memory
3656 (and updated to conform to mono code style).
3658 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
3660 * io.c: EEXISTS is ignored for directory creation.
3661 * mono-mutex.h: remove silly "pragma }" that emacs users insert
3662 because they use a broken editor:-)
3664 2002-03-28 Dick Porter <dick@ximian.com>
3670 * handles.c: Warning cleanups
3672 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
3674 * unicode.h, unicode.c: changed to gunichar2
3675 * io.h, io.c: changed strings to gunichar2*, added
3676 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
3677 some fixes to FindFirstFile() and friends.
3679 2002-03-26 Dick Porter <dick@ximian.com>
3681 * types.h: Implement the large integer struct
3684 * timefuncs.c: Dummy functions that don't yet implement
3685 QueryPerformanceCounter() and QueryPerformanceFrequency()
3688 * threads.c: Implement SleepEx()
3691 * system.c: Beginnings of GetSystemInfo()
3693 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
3697 * context.c: Dummy function that doesnt yet implement
3701 * atomic.c: Interlocked functions
3703 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
3705 * threads.c: use a gc-safe hash table to store tls pointers.
3707 2002-03-22 Dick Porter <dick@ximian.com>
3709 * threads.c: Fix a race condition where a thread can start and
3710 exit before the handle has been properly initialised (no reason
3711 why the handle couldn't be initialised beforehand, so do so)
3713 Fix a ms to ns conversion magnitude thinko.
3715 2002-03-21 Dick Porter <dick@ximian.com>
3717 * semaphores.c: Fix a problem when waiting for one or more
3718 semaphores, and another semaphore is Released (all waiting
3719 semaphores assumed they were signalled)
3721 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
3723 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
3724 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
3726 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
3728 * threads.c (Sleep): bug fix: 1ms == 1000000ns
3730 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
3732 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
3733 threads.c, io.c: added flush method to handles.
3735 * io.c: FlushFileBuffers() and FindFirstFile() functions.
3737 Thu Mar 7 17:21:52 CET 2002 Paolo Molaro <lupus@ximian.com>
3739 * threads.c, timed-thread.c, wait.c: Boehm-GC anable.
3741 2002-02-20 Dick Porter <dick@ximian.com>
3743 * io-layer.h: Always build without cygwin support on windows
3745 Mon Feb 18 15:50:59 CET 2002 Paolo Molaro <lupus@ximian.com>
3747 * sockets.c: #undef DEBUG.
3749 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
3751 * io-layer.h: conditionally include sys/filio.h and sys/sockio.h
3752 for FIONBIO, FIONREAD, and SIOCATMARK.
3754 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
3756 * sockets.c: conditionally include sys/filio.h and sys/sockio.h
3757 for FIONBIO, FIONREAD, and SIOCATMARK.
3759 2002-02-13 Dick Porter <dick@ximian.com>
3761 * sockets.c: Implement shutdown and select
3763 2002-02-13 Jeffrey Stedfast <fejj@ximian.com>
3765 * mono-mutex.[c,h]: New source files that thinly wrap all pthread
3766 functions that take pthread_mutex_t and/or pthread_mutexattr_t
3767 arguments for the sake of portability. Implements recursive
3768 mutexes and pthread_mutex_timedlock.
3770 * critical-sections.c:
3777 * wait.c: Use the mono-mutex wrapper portability functions/macros.
3779 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
3781 2002-01-23 Dick Porter <dick@ximian.com>
