1 2005-06-21 Dick Porter <dick@ximian.com>
6 * threads.c: Keep a list of owned mutexes in each thread handle,
7 so that it is easier to abandon them when the thread exits.
8 Removes a bottleneck when multiple threads are finishing in
11 2005-06-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
13 * io.c: (GetLogicalDrives) when a bogus line is read, don't leak memory.
14 When the buffer has not enough space, close the file before returning.
16 2005-06-09 Duncan Mak <duncan@novell.com>
18 * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to
19 all public headers. Fixes #74919.
21 2005-05-30 Zoltan Varga <vargaz@freemail.hu>
23 * atomic.h: Add IA64 atomic ops.
25 2005-05-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
27 * processes.c: make ExitCode be valid even if the user didn't call
28 WaitForExit() and is just polling on HasExited.
30 2005-05-17 Dick Porter <dick@ximian.com>
32 * io.c (file_getfilesize): Clear the error value, so that files
33 with sizes with the low bits 0xFFFFFFFF can be distinguished from
36 2005-05-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
38 * shared.c: forgot to ignore a warning.
40 2005-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
42 * shared.c: don't display warnings after reboots.
44 2005-05-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
46 * sockets.c: on windows, getsockopt/setsockopt for send/receive timeout
47 use an integer in milliseconds. We were using a struct timeval.
49 2005-05-06 Dick Porter <dick@ximian.com>
58 * collection.h: Use SysV semaphores for managing access to the
59 shared memory - in return for the ludicrous api we get
60 synchronisation primitives that can be cleaned up by the kernel
61 even when a process quits unexpectedly. This removes the
64 2005-05-05 Lluis Sanchez Gual <lluis@novell.com>
66 * handles.c: Always use polling in the waits, since
67 mono_cond_timedwait can't be interruped by the thread abort signal.
69 2005-04-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>
71 * events.c: calling Set on AutoResetEvent several times has the same
72 effect as calling it only once if no thread is waiting for it.
74 2005-04-29 Dick Porter <dick@ximian.com>
76 * processes.c (EnumProcesses): Use a GArray instead of a GPtrArray
77 now it's storing pids not handles, also fixes memory leak caused
78 by unclear glib documentation.
80 * sockets.c (WSACleanup): Remove unused variable
82 2005-04-29 Dick Porter <dick@ximian.com>
84 * handles.c (_wapi_handle_check_share_by_pid): For systems that
85 don't have file descriptor info in /proc check that the original
86 opener of a file is still there, if a share violation would
89 2005-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
92 * handles-private.h: added _wapi_handle_forecch that loops through all
93 the handles and call a callback function when a handle of the given
96 * sockets.c: no need to keep open sockets in an array, as we have them
97 in the handles structure.
101 2005-04-28 Dick Porter <dick@ximian.com>
103 * processes.c: Cope with handles that are only around for as long
104 as the search is running. If we're searching for process handles,
105 check to see if the process is still running and signal it if not.
107 * handles.c (_wapi_search_handle): Search in the shared space as
108 well. Fixed bug 74752.
111 * handles.c (_wapi_handle_new_from_offset):
112 _wapi_handle_new_for_existing_ns () was doing exactly the same as
115 2005-04-26 Dick Porter <dick@ximian.com>
117 * handles.c: Fix stupid thinko where if a new shared handle is
118 created but a collection was needed to free some space, it
119 returned an error anyway. Should fix the messages shown in bug
122 2005-04-25 Dick Porter <dick@ximian.com>
124 * handles.c (_wapi_handle_check_share): Only consider mono
125 processes when looking to see if a file is still being held open,
126 while checking share permissions.
128 2005-04-25 Dick Porter <dick@ximian.com>
132 * wapi-private.h (struct _WapiHandleOps):
133 * handles.c (_wapi_handle_unref): When destroying handles, save
134 the handle data and call the close function only after the array
135 slot has been cleared. This prevents race conditions with file
136 descriptors, fixing bug 74713.
138 * mutexes.c: Delete the handle close functions, they didn't do
141 * error.c (_wapi_get_win32_file_error): Add a mapping for EINTR so
142 the "Unknown error" g_warning doesn't get displayed.
144 2005-04-25 Dick Porter <dick@ximian.com>
147 * threads.c: Make thread handles process-private for now to take
148 some of the space pressure off the shared memory, while I work on
151 2005-04-21 Dick Porter <dick@ximian.com>
153 * handles.c (_wapi_handle_check_share): Make sure there is a "fd"
154 dir in /proc before blowing away handle info. Fixes bug 74649.
156 2005-04-21 Dick Porter <dick@ximian.com>
158 * wait.c (WaitForMultipleObjectsEx): Implement special waits
160 * handles.c (_wapi_handle_wait_signal_poll_share): Don't return a
161 timeout, just wait briefly for the private signals and let the
162 waiting thread test again. This prevents us missing shared
165 2005-04-21 Dick Porter <dick@ximian.com>
167 * collection.h (_WAPI_HANDLE_COLLECTION_EXPIRED_INTERVAL): Reduce
168 the time before a slot is considered too old and deleted. This is
169 a workaround while I come up with a proper fix.
171 2005-04-21 Dick Porter <dick@ximian.com>
176 * handles.c (_wapi_handle_new): Turn assertions into errors.
178 * collection.c (_wapi_handle_collect): Use symbols not magic
179 numbers for timeout values
181 2005-04-19 Dick Porter <dick@ximian.com>
185 * handles.c (_wapi_handle_count_signalled_handles)
186 * handles-private.h (_wapi_handle_shared_lock_handle): Use new
187 shared handle locks in critical sections.
189 * handles.c (_wapi_handle_new_for_existing_ns): Reuse old handles
190 if there is already one there.
192 * handles.c (_wapi_handle_ref): It was possible for a process to
193 exit before getting around to updating shared handle timestamps,
196 Tue Apr 19 16:25:47 CEST 2005 Paolo Molaro <lupus@ximian.com>
198 * threads.c: fix lookup of the thread id in the has table:
199 always use the id value, not the pointer to the id.
201 2005-04-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
203 * handles.c: fix handle returned in _wapi_handle_search_handle. Dick
206 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
208 * io-layer/sockets.c: FIONBIO with a TRUE argument means we want
209 non-blocking IO, not the other way around.
211 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
215 * handles-private.h: GetFileType wasn't checking if we have memory
216 allocated for the handle before dereferencing it. Fixes a FileStream
219 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
223 * handles-private.h: we were calling g_renew to expand the handle array,
224 but that might move the memory and we might have pthread conditions or
225 mutexes in the original memory area that are being used. Now instead of
226 expanding an existing array, we just create new ones and keep a list of
227 them. Access to _wapi_private_handles had to be modified accordingly.
229 2005-04-15 Dick Porter <dick@ximian.com>
231 * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN
233 2005-04-14 Raja R Harinath <rharinath@novell.com>
235 * wapi-private.h: Remove reference to 'daemon-private.h'.
237 Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro <lupus@ximian.com>
239 * atomic.h: applied patch from mass@akuma.org (David Waite)
240 to fix InterlockedExchangeAdd.
241 Fixed a few other functions, including InterlockedCompareExchange()
242 which was miscompiled by gcc with optimizations enabled.
244 2005-04-13 Dick Porter <dick@ximian.com>
246 * io.c (share_check):
247 * handles.c (_wapi_handle_check_share): Refine the file check so
248 that sharing violations within the same process don't cause
251 2005-04-13 Dick Porter <dick@ximian.com>
253 * io.c (FindFirstFile): Fix bugs introduced with the merge (bug
256 2005-04-12 Dick Porter <dick@ximian.com>
258 The daemon-less io-layer. Extensive lowlevel changes in
259 handles.c, requiring some corresponding changes in other files
260 calling these functions. Private_foo structures have been
263 File descriptor handling differences account for most of the
264 changes in io.c and sockets.c.
268 * mutexes.c: Named mutexes are now a distinct type.
269 * atomic.h: Fix a PPC uninitialised variable warning.
270 * wait.c: Check conditions before waiting on a condition variable.
271 * processes.c: Handle process fork and wait without a daemon
272 (though this has the limitation of only being able to wait for
275 2005-04-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
282 * sockets.h: removed dead code that deals with async IO.
284 2005-03-30 Zoltan Varga <vargaz@freemail.hu>
286 * atomic.c (InterlockedIncrement): Fix fallback implementation of
287 InterlockedIncrement and InterlockedDecrement. Fixes #74228.
289 2005-03-29 Sebastien Pouliot <sebastien@ximian.com>
291 * io-layer.h: Add required header files for compiling with VS.NET.
293 2005-03-17 Miguel de Icaza <miguel@novell.com>
295 * io.c: don't fail on NFS when there are no more locks available.
297 2005-03-09 Dick Porter <dick@ximian.com>
299 * error.c (_wapi_get_win32_file_error): ENFILE and EMFILE should
300 map to ERROR_TOO_MANY_OPEN_FILES, not ERROR_NO_MORE_FILES. Fixes
303 2005-03-09 Dick Porter <dick@ximian.com>
305 * daemon.c (process_process_fork): Initialise the handle data
306 before using it in the error case. This is probably the error
307 we're working around in the previous change. Spotted by Taru Jain
308 <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.
310 2005-03-07 Dick Porter <dick@ximian.com>
312 * daemon.c: It looks like g_shell_parse_argv() can return
313 argv[0]=NULL somehow, yet still not give an error. Make sure we
314 don't pass NULL to strrchr(), working around a segfault that
315 showed up on ZLM testing.
317 2005-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
319 * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is
320 the expected error code showed by the test case in bug #73053.
322 2005-02-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
324 * io.c: another leftover.
326 Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>
328 * io.c: fixed logic in checking errno in rev 40815.
330 Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>
332 * threads.c: we don't depend on the GC checking tls
334 * processes.c: remove unused ref to GC headers.
336 Thu Feb 17 19:57:11 CET 2005 Paolo Molaro <lupus@ximian.com>
338 * io.c: remove _wapi_thread_cur_apc_pending () checks
339 when the siscall should return immediatly and handle
340 the case when a syscall is interrupted without
341 erroring out, but returning a 0 read/write if possible.
342 Still the cases of read from file need to be handled.
344 Tue Feb 8 18:28:11 CET 2005 Paolo Molaro <lupus@ximian.com>
346 * threads.c: make people test with 1 MB stack per thread.
348 2005-01-17 Dick Porter <dick@ximian.com>
350 * timefuncs.h: Make WapiFileTime endian-aware, as it's often
351 cast to and from 64bit ints. Fixes bug 71213.
353 2005-01-11 Dick Porter <dick@ximian.com>
355 * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
358 Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>
360 * atomic.h: Fix functions on s390.
362 Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>
364 * atomic.h: fix some functions on ppc (tests/interlocked.cs).
366 2005-01-10 Dick Porter <dick@ximian.com>
368 * misc.c (_wapi_calc_timeout): Guard against overflow when
369 calculating timeouts. This makes waiting with a large
370 (Int32.MaxValue) timeout not return immediately.
372 2004-12-23 Ben Maurer <bmaurer@ximian.com>
374 * io.c (io_ops): make this `const' so it is shareable (well, only
375 really shareable if it is statically linked...)
377 Mon Dec 20 11:58:33 CET 2004 Paolo Molaro <lupus@ximian.com>
379 * threads.c, threads.h: add accessor to get the pthread_key_t for
382 2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
384 * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS
385 if it exists and is not the same as 'src'.
387 2004-12-01 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
389 * atomic.h : Fix InterlockedCompareExchange for s390/s390x.
391 2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
393 * processes.c: unquote the cmd path, allow for ' or " when quoting and
394 pass the quoted program name to the daemon, otherwise the call to
395 g_shell_unquote in the daemon will break things up.
397 2004-10-14 Dick Porter <dick@ximian.com>
399 * sockets.c (_wapi_accept): Revert the previous change. We now
400 set the accepted socket to have the same blocking status as the
401 listening socket in managed code. This follows MS behaviour.
403 2004-10-14 Dick Porter <dick@ximian.com>
405 * sockets.c (_wapi_accept): On Darwin, make sure a newly
406 accept()ed socket is blocking. Fixes bug 67355, patch by
407 grompf@sublimeintervention.com.
409 2004-10-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
411 * system.c: check the number of online processors instead of the
412 existing ones. Sanitize return value if it's an error.
414 2004-10-03 Ben Maurer <bmaurer@ximian.com>
416 * system.c: Add support for getting the # of cpus.
418 2004-09-28 Dick Porter <dick@ximian.com>
420 * io.c (pipe_close_private): Fix one small typo in the last change
421 that totally hosed process creation with redirected pipes.
423 2004-09-24 Dick Porter <dick@ximian.com>
430 * handles-private.h: Cope when a file descriptor is reused while
431 the handle that thought it owned it is still referenced, instead
432 of asserting. Probably fixes bug 66479, though we've been unable
435 2004-09-09 Dick Porter <dick@ximian.com>
438 * io.c: Set error codes everywhere.
440 2004-09-06 Dick Porter <dick@ximian.com>
442 * handles.c (_wapi_handle_unref): Reset the private record's type
443 (CloseHandle): Check for a fd mapping failure, and return FALSE.
444 (_wapi_handle_process_fork): Fix long-standing bug in checking
445 handle return values. Also do the required bookkeeping with the
446 new process's handles.
448 * daemon.c: When creating a new process's handles, check whether
449 the shared space needs to be increased
451 2004-09-05 Zoltan Varga <vargaz@freemail.hu>
453 * shared.c (_wapi_shm_file): Fix leaking of filename.
455 2004-08-19 Dick Porter <dick@ximian.com>
457 * handles.c (_wapi_handle_count_signalled_handles): Fix thinko
458 introduced with the fd offset stuff: unlock handles properly when
459 backing off. Fixes the monologue hang at exit.
461 2004-08-18 Dick Porter <dick@ximian.com>
464 * io.c: Check that new fds fit in the table, return error if not
466 * daemon.c (_wapi_daemon_main):
467 * handles.c (shared_init): Have all processes agree on a size for
470 2004-08-17 Dick Porter <dick@ximian.com>
472 * daemon.c (process_new):
473 * handles.c (_wapi_handle_new_internal): Cope when the space
474 reserved for file descriptors is larger than the shared segment
475 size. Fixes the crash reported when running mono under gdb on
478 2004-08-16 Dick Porter <dick@ximian.com>
482 * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
483 error checking with passed-in file descriptors.
485 2004-08-11 Dick Porter <dick@ximian.com>
488 * io.c: Returned handle values are the file descriptor the handle
493 * daemon.c: Reserve the range of handles that can have the same
494 values as file descriptors. These won't be used, but the values
495 will be used as file, console, pipe or socket handles. The fd to
496 handle mapping is done internally and is invisible to users.
499 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
500 reserve a chunk of handle space.
502 2004-08-04 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
504 * atomic.h: add support for 64-bit S/390
506 2004-07-22 Dick Porter <dick@ximian.com>
509 * threads.c: Move the destruction of the internal thread data to
510 after the thread has been joined. Fixes bug 61418.
512 2004-07-14 Dick Porter <dick@ximian.com>
514 * wait.c (test_and_own): When not waiting for all handles to
515 become signalled, only own and return the lowest. All the
516 documentation suggests that the old way was correct, but
517 experimentation shows it actually works like this. Patch by
518 Sébastien Robitaille
519 (sebastien.robitaille@croesus.com), fixes bug 61511.
521 2004-07-09 Ben Maurer <bmaurer@ximian.com>
523 * threads.c: register roots for gc
525 2004-07-08 Dick Porter <dick@ximian.com>
527 * io.c (file_seek): If there is a high 32bit offset part, make
528 sure the low part isn't sign-extended. Set error codes when
529 returning failure. Fixes bug 61131.
531 2004-07-06 Dick Porter <dick@ximian.com>
533 * io.c (file_setfiletime): Check for underflow when converting to
534 time_t values. Set error codes when returning failure. Fixes bug
537 2004-07-05 Dick Porter <dick@ximian.com>
539 * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable.
541 * daemon.c (unref_handle): Only destroy a handle if all processes
542 have released it, not just the current one. Fixes bug 60887.
544 2004-06-30 Zoltan Varga <vargaz@freemail.hu>
546 * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
549 2004-06-24 Dick Porter <dick@ximian.com>
551 * mutexes.c: Indicate when a named mutex was reused
553 2004-06-24 Dick Porter <dick@ximian.com>
555 * threads.c (SuspendThread):
556 * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a
557 while loop. See bug 58161.
559 Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro <lupus@ximian.com>
561 * io.c: don't use sharemode for on-disk file permissions: it's used
562 for shared access to the open file.
564 2004-06-22 Dick Porter <dick@ximian.com>
566 * events.c (CreateEvent): When creating an auto-reset event that
567 is initially owned, make sure the set count starts at 1.
569 2004-06-18 Dick Porter <dick@ximian.com>
572 * events.c: Auto-reset events need to release one thread for each
573 time SetEvent() is called. Fixes bug 41292.
577 * mutexes.c: Scan for mutexes that are still locked by a thread
578 when it exits. Fixes the MS demo app linked by bug 41292.
580 * wait.c (test_and_own): Make sure a handle is signalled before it
583 2004-06-16 Dick Porter <dick@ximian.com>
585 * timed-thread.c: Call the thread cleanup exit routine before taking
586 the join mutex, because this could deadlock if another thread tries
587 to join in the meantime. This fixes the hang-at-exit problem seen
590 2004-06-03 Lluis Sanchez Gual <lluis@ximian.com>
592 * threads.c: Implemented SleepEx.
593 * threads.h: Fixed SleepEx signature.
595 2004-06-03 Miguel de Icaza <miguel@ximian.com>
597 * threads.c: When running under valgrind, do not allocate too much
598 stack, as Valgrind default is 1 meg.
600 2004-05-27 Dick Porter <dick@ximian.com>
603 * io.c: Implemented LockFile() and UnlockFile()
605 2004-05-21 Dick Porter <dick@ximian.com>
607 * io.c (CreateFile): Check for existing share modes when opening
613 * daemon.c: Maintain a hash of file share modes, keying on device
614 and inode (to cope with symlinks.)
616 2004-05-20 Lluis Sanchez Gual <lluis@ximian.com>
618 * daemon-messages.c: Retry if the communication with the daemon is
619 interrupted by a signal.
620 * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped.
621 Only return an error in this case if there is something in the apc queue
622 (which means that it is an interruption requested by the "user").
623 * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as
624 true since the wait is small.
625 * shared.c: Retry write calls when interrumped by a signal.
626 * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which
627 returns TRUE if there are pending asynchronous calls (APC) for the
628 provided thread. Also added _wapi_thread_dispatch_apc_queue which calls
629 the enqueued APCs. Defined a new struct ApcInfo that holds information
630 about an enqueued APC.
631 * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same
632 as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue.
633 These last two methods call the corresponding apc methods in
634 thread-private using the provided thread handle.
635 * threads.h: Added QueueUserAPC.
636 * uglify.h: Added WapiApcProc (needed by QueueUserAPC).
637 * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and
638 WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support
639 for APCs in those two methods and also in SleepEx.
641 2004-05-17 Dick Porter <dick@ximian.com>
643 * io.c (CopyFile): Speed up. Fixes bug 57859.
645 2004-05-13 Dick Porter <dick@ximian.com>
646 * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current
647 thread doesn't own the mutex, rather than assert()ing.
649 2004-05-11 Dick Porter <dick@ximian.com>
651 * shared.c (_wapi_shm_attach): Cope when a previous daemon startup
652 attempt failed, leaving shared files that look like a daemon is
655 2004-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
658 (SetFileAttributes): don't the the exec bit if the corresponding read
661 2004-05-10 Zoltan Varga <vargaz@freemail.hu>
663 * io.c (FindFirstFile): Fix invalid free.
665 2004-05-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
667 * io.c: translate from GFileError to errno codes and don't free
668 variables right after calling mono_io_scandir, as we may overwrite
671 2004-05-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
673 * io.c: g_dir_open return ENOENT for directories on which we don't have
674 read/execute permission, while returning EPERM for anything below those.
675 So, change ENOENT by EPERM if the directory exists.
677 2004-05-07 Dick Porter <dick@ximian.com>
679 * io.c (SetFileAttributes): Don't have failed chmod()s cause a
680 "file not found" error. Fixes bug 54032.
682 2004-05-07 Dick Porter <dick@ximian.com>
684 * io.c (FindFirstFile): Comment out a windows-compatibility check
685 that breaks when directories have metachars in their names.
686 Workaround for bug 58116.
688 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
690 * io.c: fixed for FindFirstFile for empty directories. Closes
693 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
695 * processes.c: set the start time for the current process. Fixes bug
698 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
700 * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
701 * io.c: implemented scandir using glib functions.
703 2004-05-04 Dick Porter <dick@ximian.com>
705 * daemon.c (read_message): Return FALSE on error so the GSource
706 callback itself can return FALSE. Cures the infinite loop poll()
708 * shared.c: Fix some daemon startup race conditions.
710 2004-04-29 Miguel de Icaza <miguel@ximian.com>
712 * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k,
713 use the stack, do not use dynamic memory.
715 2004-04-29 Zoltan Varga <vargaz@freemail.hu>
717 * io.c: Add scandir implementation for platforms which do not have
720 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
722 * io.[ch]: implemented GetLogicalDriveStrings.
724 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
727 * sockets.c: use the field name from configure when accessing sigval
728 pointer field. Makes this work on the Mac.
730 2004-04-28 Bernie Solomon <bernard@ugsolutions.com>
732 * atomic.c: (InterlockedExchange) fix typo for
735 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
738 * sockets.c: added check for sys/aio.h.
740 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
742 * error.[ch]: added _wapi_get_win32_file_error...
743 * io.c: ... which was _wapi_get_win32_error here.
744 * sockets.c: rename the function calls here too.
746 2004-04-28 Dick Porter <dick@ximian.com>
748 * daemon-messages.c: Avoid a deadlock when a thread is killed while
749 waiting for the daemon by using a recursive mutex. Helps bug 56699.
751 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
753 * io.c: fixed leak in async_notifier().
755 * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl
758 * threads.c: removed old comment.
760 2004-04-26 David Waite <mass@akuma.org>
769 * wapi-private.h: remove comma from end of enumeration declarations
770 * status.h: cast unsigned int types to int for enum assignment
772 2004-04-26 David Waite <mass@akuma.org>
775 * timefuncs.c: declare 64-bit constants as long long types (i.e.
778 2004-04-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
780 * socket-wrappers.h: _wapi_socket == WSASocket now. Added
783 * sockets.c: new unused parameters for _wapi_socket.
785 2004-04-22 Miguel de Icaza <miguel@ximian.com>
787 * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle
788 the fact that MacOS X is a piece of junk (sem_init is *defined* in
789 the libc, but they return `not implemented').
791 2004-04-22 Dick Porter <dick@ximian.com>
794 * handles-private.h: Reference the handle when it is locked, so
795 that another thread can't blow it away while we're waiting for it
811 * critical-sections.c:
812 * atomic.c: Added pthreads cleanup handlers and error asserts
815 * handles.c: Fixed the gcc "variable might be used uninitialised"
816 warnings. They can't happen, but gcc doesn't know that
817 g_assert()s don't return.
819 Fixed the declaration of _wapi_handle_process_kill() so that it
820 expects the correct type for the pid.
822 * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that
823 hasn't been used in ages and just made the code more complex.
825 2004-04-17 Zoltan Varga <vargaz@freemail.hu>
827 * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
828 warnings. Fixes #57168.
830 2004-04-16 Dick Porter <dick@ximian.com>
832 * threads.c (Sleep): Using div(3) with a negative (when signed)
833 numerator causes the quotient to be 0 and the remainder to be the
834 numerator. This feeds a small negative value to nanosleep(3),
835 which will return immediately and cause a busy wait. Fixes bug
838 2004-04-15 Dick Porter <dick@ximian.com>
841 * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3)
842 and fnmatch(3) instead of glob(3). glob() can't cope with being
843 given filenames containing metachars. This fixes bug 40557.
845 2004-04-14 Bernie Solomon <bernard@ugsolutions.com>
847 * security.c: #warning is a GCC-ism
849 2004-04-13 Sebastien Pouliot <sebastien@ximian.com>
851 * security.c: Removed GetUserName as glib g_get_user_name does a
852 better (portability) job. Added ImpersonateLoggedOnUser and
855 2004-04-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
857 * mono-mutex.h: move pthread_mutex_timedlock declaration to...
858 * mono-mutex.c: ...here. It was causing a warning that prevented
859 libgdiplus compilation.
861 2004-04-04 Miguel de Icaza <miguel@ximian.com>
863 * security.c (GetUserName): Make it work on MacOS X
865 2004-04-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
867 * security.c: use getpwuid_r if available. This one is thread-safe.
869 2004-04-02 Sebastien Pouliot <sebastien@ximian.com>
871 * Makefile.am: Added security.c|h.
872 * security.c: New file for security related functions. Added function
873 GetUserName to fix #56144.
874 * security.h: New. Header file for security.c
875 * wapi.h: Added include for security.h
877 2004-03-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
879 * daemon-messages.h: added kill structs.
881 * daemon.c: implemented process_process_kill.
882 * handles-private.h: define process_process_kill.
883 * handles.c: implemented _wapi_handle_process_kill.
884 * processes.[ch]: implemented TerminateProcess.
886 2004-03-25 Bernie Solomon <bernard@ugsolutions.com>
888 * daemon.c (rem_fd): On solaris you seem to get an
889 error even after removing the input source so don't
890 try and rem_fd it twice.
892 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
894 * daemon.c: in process_post_mortem, If the child terminated due to the
895 receipt of a signal, the exit status must be based on WTERMSIG, since
896 WEXITSTATUS returns 0 in this case.
898 2004-03-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
900 * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.
902 2004-03-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
904 * daemon.c: only call getdtablesize () once.
905 * processes.c: wait 500 ms to check if execve failed and throw the same
906 exception as MS on failure. Fixes bug #32809.
908 2004-03-17 Bernie Solomon <bernard@ugsolutions.com>
910 * io.c (async_notifier): use "union sigval" rather
911 than sigval_t as Solaris doesn't have sigval_t
912 (which isn't in IEEE 1003.1 either).
914 2004-03-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
916 * io.c: added debug stuff and removed a few redundant lines in
919 2004-03-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
921 * io-private.h: added new fields for file structure. Declare
922 _wapi_io_add_callback.
924 * io.c: added _wapi_get_win32_error, support aio_read/write in
925 file_read/write. Implemented _wapi_io_add_callback, which is where
928 * io.h: added new fields for WapiOverlapped and typedef for the
931 * processes.c: fixed off-by-one bug when handling environment variables
934 * threads.[ch]: implemented BindIoCompletionCallback.
936 * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE.
938 2004-03-14 Zoltan Varga <vargaz@freemail.hu>
940 * socket-wrappers.h: Remove extra semicolon.
942 2004-03-03 Dave Camp <dave@ximian.com>
944 * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
945 Use a new main context.
947 2004-03-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
950 (GetFileAttributes): set the error depending on errno instead of
951 setting ERROR_FILE_NOT_FOUND always. See bug #55160.
953 2004-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
956 (CopyFile): free the buffer on error.
958 (WSAIoctl): free the buffer on error.
960 2004-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
962 * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT.
964 * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW
965 using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style.
967 2004-01-27 Bernie Solomon <bernard@ugsolutions.com>
969 * shared.c (_wapi_shm_file): add hostname
970 to shared data file names to handle NFS mounted
973 Mon Jan 26 16:15:03 CET 2004 Paolo Molaro <lupus@ximian.com>
975 * sockets.h: remove obsolete soklen_t typedef.
977 Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>
979 * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket
980 wrappers to its own non-installed header file.
982 2004-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
985 (FindFirstFile): unlock the handle if FindNextFile fails.
986 (FindNextFile): g_free a couple of pointers before retrying.
989 (WaitForMultipleObjects): if only one handle provided, use
992 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
994 * handles-private.h: (_wapi_handle_type) check
995 for segment in range before using it
997 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
999 * thread-private.h: _wapi_thread_ops is now const
1002 Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>
1004 * threads.c, timed-thread.c, timed-thread.h: use mach
1005 semaphores on Darwin (MacOSX) since the posix ones
1006 are mostly broken there (threads are not created suspended
1007 and they can start executing before they are fully initialized
1008 like in tests/thread-static.cs).
1010 Mon Dec 22 17:18:45 CET 2003 Paolo Molaro <lupus@ximian.com>
1012 * atomic.h: ppc fixes.
1014 2003-12-19 Bernie Solomon <bernard@ugsolutions.com>
1016 * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
1019 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
1021 * shared.c: (_wapi_shm_open) make scratch file
1022 not have to immediately regrow to avoid remaps
1023 (HPUX can't cope with these).
1024 (_wapi_shm_attach) use actual size of file
1025 to set scratch data_len for the creating process.
1027 * handles.c: (_wapi_handle_new_internal) make
1028 sure mutex & cond var are initialized even for
1029 non process shared ones.
1030 (_wapi_handle_unref) always call destroy
1031 routines on mutex & cond var
1033 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
1035 * daemon.c: change channel data structure so
1036 input sources are removed from glib event loop
1037 properly. xsp works better on Solaris and
1040 2003-12-12 Bernie Solomon <bernard@ugsolutions.com>
1042 * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
1043 definition with file & line number for non-GCC
1046 2003-12-08 Bernie Solomon <bernard@ugsolutions.com>
1048 * Makefile.am: make sure hppa_atomic.s is in distribution
1050 2003-12-01 Dick Porter <dick@ximian.com>
1053 * mutexes.c (CreateMutex):
1054 * mutex-private.h (struct _WapiHandle_mutex):
1055 * handles.c: Look up certain handle types by name, in a shared
1056 namespace. Currently only mutex handles have this implemented.
1059 * semaphores.c (CreateSemaphore):
1060 * events.c (CreateEvent): Fix signature
1062 2003-11-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1064 * io.c: don't call g_free before testing errno as it may modify it.
1065 If the path exists, return an error if it's not a directory. Fixes
1068 2003-11-20 Dick Porter <dick@ximian.com>
1070 * io.c: Missed a little-endian UTF16 conversion. Patch from
1071 Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.
1073 2003-10-29 Dick Porter <dick@ximian.com>
1075 * io.c (MoveFile): If the move crosses filesystems, try and fall
1076 back to copy and delete. Patch from Jörg Rosenkranz
1077 (JoergR@voelcker.com), fixes bug 50298.
1079 2003-10-28 Dick Porter <dick@ximian.com>
1081 * io.c: Use the new encoding conversion to cope with non-utf8
1082 locales in filenames.
1084 * processes.c: Ditto for process arguments.
1086 Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro <lupus@ximian.com>
1088 * atomic.h: some ppc inline asm fixes (incorrect use of labels,
1089 incorrect register constraints, incorrect clobber lists).
1091 2003-10-13 Bernie Solomon <bernard@ugsolutions.com>
1093 * Makefile.am hppa_atomic.s: add HP 64bit
1094 implementation of atomic ops
1096 2003-10-13 Zoltan Varga <vargaz@freemail.hu>
1098 * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
1099 a conditional for platforms that don't have it.
1101 2003-10-09 Bernie Solomon <bernard@ugsolutions.com>
1103 * threads.c: (CreateThread) use stacksize argument
1104 if non-zero - change default for 64 bits to 4Mb
1106 2003-09-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1108 * sockets.c: set last error when socket creation fails. This shed some
1109 light on bug #49015.
1111 2003-09-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1113 * processes.c: fixed bug #48973: we only change \ by / for the argument
1114 to be used as command.
1115 When getting the program name from the args, don't let the space between
1118 2003-09-24 Bernie Solomon <bernard@ugsolutions.com>
1120 * atomic.h atomic.c: fix sparc so lock is
1121 global, increment does so and it compiles under Sun compiler.
1123 2003-09-22 Bernie Solomon <bernard@ugsolutions.com>
1125 * handles.c: include <string.h> directly as may
1126 not be nested in <sys/un.h> like Linux
1128 2003-09-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1131 (DeleteFile): call SetLastError on failure. Fix by
1132 richard.torkar@htu.se (Richard Torkar). Closes bug #48222.
1134 2003-09-15 Lluis Sanchez Gual <lluis@ximian.com>
1136 * daemon.c: In compare_process(), discard handles already signalled.
1138 2003-09-02 Dick Porter <dick@ximian.com>
1140 * io.c: Work around glib brain-dead assumptions about utf8-encoded
1141 filenames. Fixes bug 30781.
1143 2003-08-28 Dick Porter <dick@ximian.com>
1145 * critical-sections.c: Patch from Bernie Solomon
1146 <bernard@ugsolutions.com> to emit a warning if locking a critical
1149 2003-07-23 Dick Porter <dick@ximian.com>
1152 * daemon.c (maybe_exit): Avoid the race condition when the daemon is
1153 closing but another client comes along when the shared data is still
1154 visible. Should fix bugs 33671 and 35213.
1156 2003-07-23 Dick Porter <dick@ximian.com>
1158 * handles.c: Initialise handle mutex and cond. Fix by
1159 Bernie Solomon <bernard@ugsolutions.com>
1161 2003-07-15 Dick Porter <dick@ximian.com>
1163 * timed-thread.c (timed_thread_start_routine): Fix virtual memory
1164 leak when threads quit. Fixes bug 44067.
1166 Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro <lupus@ximian.com>
1168 * io.c: never add write permission for group or others in
1169 SetFileAttributes ().
1171 2003-06-17 Dick Porter <dick@ximian.com>
1173 * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
1174 ignore the unsupported ones ("fixes" bug 44977).
1176 2003-06-17 Lluis Sanchez Gual <lluis@ximian.com>
1178 * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for
1179 high ms values (there was an overflow).
1181 2003-06-17 Zoltan Varga <vargaz@freemail.hu>
1183 * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.
1185 2003-06-11 Dick Porter <dick@ximian.com>
1187 * shared.c: Fix shared directory creation. Patch from
1188 Pablo Baena <pbaena@uol.com.ar>
1190 2003-06-10 Dick Porter <dick@ximian.com>
1192 * atomic.c: Delete the useless compile warning
1194 2003-06-09 Dick Porter <dick@ximian.com>
1196 * daemon.c: Lookup env as a string array. Fixes bug 44289. Also
1197 make setting the process handle value in the environment actually
1200 * processes.c: Pretty up the process name, if it happens to be
1201 "mono" such as when another mono process forks "mono foo.exe"
1203 2003-06-05 Dick Porter <dick@ximian.com>
1205 * processes.c (process_set_current): Don't do an expensive handle
1206 search at application startup, check the environment to see if the
1207 process handle has already been created.
1209 * io.c: Don't do an expensive handle search when creating stdin,
1210 stdout and stderr handles, just create them all the first time one
1217 * handles-private.h:
1218 * daemon-messages.h:
1220 * daemon.c: Support for "unlimited" number of handles and scratch
1223 Speed up application startup by passing process handle in the
1224 environment, rather than let the app scan all handles (which gets
1225 really slow when there are more than a few thousand to check.)
1227 Initialise some structs passed to syscalls, noticed by valgrind.
1230 2003-05-20 Dick Porter <dick@ximian.com>
1232 * io.c (FindFirstFile): Include . files in the glob. Fixes bug
1235 2003-05-19 Dick Porter <dick@ximian.com>
1237 * threads.c: Set the new thread's stack size to 2M. Fix needed
1238 for BSD, reported by Martin Dvorak <md@9ll.cz>
1240 2003-05-16 Dick Porter <dick@ximian.com>
1243 * io.c: Implement GetTempPath()
1245 2003-05-16 Dick Porter <dick@ximian.com>
1247 * processes.c (CreateProcess): Set some error codes
1249 2003-05-12 Dick Porter <dick@ximian.com>
1251 * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
1252 Patch from Martin Dvorak <mdvorak@ninell.cz>.
1254 2003-05-10 Dick Porter <dick@ximian.com>
1256 * io.c (CopyFile): Copy file mode as well as file data. Based on
1257 suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
1260 2003-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1262 * handles.c: don't call GC_gcollect when creating new handles.
1264 2003-05-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1266 * handles.c: added some debugging code. Call GC_gcollect
1267 before creating a new handle. It makes Lupus' test run smoother and
1268 faster (from 62 to 83 request per second). Notice that calling
1269 GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does
1270 not improve nor degrade the performance, so i don't do it.
1272 2003-05-02 Dick Porter <dick@ximian.com>
1274 * sockets.c: Rearrange closesocket() and socket_close_private(),
1275 and remember to unref the handle, so we don't leak socket handles.
1276 Fix from Pelle Johnsen <pelle.johnsen@mail.dk>
1278 2003-04-11 Dick Porter <dick@ximian.com>
1280 * atomic.h: ARM atomic operations by Malte Hildingson
1281 <tds00mahi@tellus.thn.htu.se>
1283 Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>
1285 * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.
1287 2003-04-03 Martin Baulig <martin@ximian.com>
1289 The following change is conditional to `WITH_INCLUDED_LIBGC'
1290 which is not yet enabled by default.
1292 * threads.c (SuspendThread, ResumeThread): Fully implemented this.
1293 (gc_init): New static function; install a signal handler for
1294 SIGPWR which is used to suspend threads. [FIXME: it SIGPWR
1295 doesn't exist on all Unix systems, we need to find another
1297 (mono_wapi_push_thread_stack): New public function. Tells the
1298 garbage collector about the current stack pointer of a suspended
1301 2003-04-03 Martin Baulig <martin@ximian.com>
1303 * timed-thread.h (TimedThread): Added `suspended_sem',
1304 `suspend_count' and `stack_ptr'.
1306 2003-03-28 Dick Porter <dick@ximian.com>
1308 * atomic.h: PPC support gratiously donated to the public domain
1309 by John Duncan <jddst19@mac.com>
1311 2003-03-20 Dick Porter <dick@ximian.com>
1313 * sockets.c (_wapi_connect): If connect() fails with EACCES, try
1314 setting SO_BROADCAST and connecting again. Fixes bug 39178.
1316 2003-03-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1318 * processes.c: included Jerome Laban's patch and call SetLastError when
1319 the executable is not found.
1321 2003-03-03 Dick Porter <dick@ximian.com>
1323 * io.c (CreateFile): Try opening directories readonly, so that
1324 timestamps can be adjusted. Patch by Elan Feingold
1325 <efeingold@mn.rr.com>.
1327 2003-02-25 Dick Porter <dick@ximian.com>
1329 * shared.c (_wapi_shm_attach): Return a failure code on system
1330 call errors, rather than exiting.
1332 2003-02-21 Dick Porter <dick@ximian.com>
1334 * processes.c (GetCurrentProcessId): Use the current process
1335 handle to return the process ID, as getpid() is unreliable
1336 (linuxthreads gives each thread a different pid). Fixes bug
1339 2003-02-21 Dick Porter <dick@ximian.com>
1341 * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug
1344 2003-02-11 Dick Porter <dick@ximian.com>
1347 * timefuncs.c: Added GetTickCount()
1349 2003-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1351 * error.c: added WSA_EHOSTUNREACH mapping.
1353 2003-01-26 Miguel de Icaza <miguel@ximian.com>
1355 * io.c (SetFileAttributes): This routine is not currently
1356 implemented for the general case, but I added a special case to
1357 set the executable bit on Linux.
1359 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
1361 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
1363 2003-01-08 Dick Porter <dick@ximian.com>
1365 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
1367 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
1369 * daemon.c, handles-private.h, handles.c, wapi-private.h:
1370 Check for an implementation which says it supports
1371 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
1372 defines the symbol. Defined but with a value of -1 still
1373 means that it is unsupported.
1375 2002-12-08 Martin Baulig <martin@ximian.com>
1377 * handles.c (_wapi_handle_new): Create new non-shared handles with
1378 an initial refcount of 1, not 0.
1380 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
1382 * threads.c (TlsGetValue): removed unnecessary mutex
1384 2002-11-20 Dick Porter <dick@ximian.com>
1386 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
1387 need to store their data structure too.
1389 * threads.c: Make sure the threading data is initialised wherever
1392 2002-11-15 Dick Porter <dick@ximian.com>
1394 * timed-thread.c: Removed unneeded parameters in
1395 _wapi_timed_thread_attach().
1397 * threads.c: Renamed AttachThread() to make it not look like
1398 external API. Removed unneeded parameters.
1400 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1402 * error.[ch]: added errno_to_WSA (). It displays a warning and return
1403 WSASYSCALLFAILURE if there is no error mapping for the given errno,
1405 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
1407 2002-10-31 Dick Porter <dick@ximian.com>
1410 * io.c: Define and use INVALID_FILE_ATTRIBUTES
1412 2002-10-07 Dick Porter <dick@ximian.com>
1415 * daemon.c: Use a more accurate time source for process start and
1418 2002-10-03 Dick Porter <dick@ximian.com>
1422 * threads.c: Fixes for freebsd. Make sure that mutex and condition
1423 creation and deletion happen in the process that owns them, when
1424 POSIX shared thread objects aren't supported. This breaks on
1425 freebsd, as pthread_t is a pointer to data.
1427 2002-10-02 Dick Porter <dick@ximian.com>
1429 * shared.c: Use mmap() instead of sysv shm for the shared data.
1431 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
1435 * daemon.c: mmap()ed regions survive fork, so just pass the
1436 pointer to _wapi_daemon_main instead of mapping it again.
1438 2002-10-01 Dick Porter <dick@ximian.com>
1440 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
1441 Unfortunately libgc uses the same thread suspend technique that I
1442 want to, and the two don't mix: libgc will deadlock when it tries
1443 to stop the world if a thread has already been suspended by
1444 someone else. Just do the simple suspended create rather than the
1445 general purpose thread suspension for now.
1447 * threads.c: Pass create flags to the timed_thread create call, to
1448 implement suspended thread creation. ResumeThread() partially
1449 implemented, to cope with the case where a newly created but
1450 suspended thread is launched.
1452 2002-09-30 Dick Porter <dick@ximian.com>
1454 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
1457 2002-09-27 Dick Porter <dick@ximian.com>
1459 * semaphores.c: Only include semaphore.h if it's present. Patch
1460 for BSD from jmmv@hispabsd.org (Julio Merino).
1462 2002-09-27 Dick Porter <dick@ximian.com>
1464 * processes.c: Pass environment and working directory to the
1465 daemon when forking. Don't let argv[0] be duplicated when looking
1466 for the program name. Implement EnumProcessModules (simple
1467 version for now, lsof-style later if needed), GetModuleBaseName,
1468 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
1469 aren't available on Linux).
1471 * process-private.h: Store the process name, and the working set
1475 * handles-private.h: New functions to store and retrieve an array
1476 of strings in the scratch space
1478 * daemon.c: Don't miss deleting some handles when a client exits
1479 (we used to rely on the client doing the final cleanup, but
1480 obviously if the client is no longer there the daemon has to do
1483 Process forking now sets the environment and the working
1486 * io.c: Don't confuse fd 0 with an unassigned handle struct
1488 * atomic.h: Add a google cache alternative to the msdn URL
1490 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1493 (_wapi_recvfrom): added ECONNRESET to the switch.
1495 2002-09-24 Mark Crichton <crichton@gimp.org>
1497 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
1500 2002-09-19 Mark Crichton <crichton@gimp.org>
1502 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
1503 dont have Linux's abstract filesystem for sockets.
1505 2002-09-19 Mark Crichton <crichton@gimp.org>
1507 * atomic.h: Added SPARC atomic asm code.
1508 * daemon.c, handles-private.h, handles.c, wapi-private.h:
1509 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
1510 Solaris 9, however, the code paths don't seem to work. More testing
1511 on the shared case is *really* needed.
1513 2002-09-03 Dick Porter <dick@ximian.com>
1516 * threads.c: Removed PosixKillThread(), because it's not in the
1519 2002-08-20 Dick Porter <dick@ximian.com>
1521 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
1522 multiples of 4 bytes, to keep header structures aligned. Needed
1523 for sparc, at least. (Patch from crichton@gimp.org)
1525 * handles.c: Removed 'disable_shm' variable (we've defaulted to
1526 building with shm enabled for months now)
1528 2002-08-19 Dick Porter <dick@ximian.com>
1530 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
1531 for legacy NeXT-based systems.
1533 2002-08-12 Dick Porter <dick@ximian.com>
1535 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
1536 from Joseph Wenninger <kde@jowenn.at>)
1538 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
1540 * threads.c: use fast spinlocks by default
1542 2002-08-02 Dick Porter <dick@ximian.com>
1544 * io.c (GetStdHandle): Add a handle reference when returning a
1545 duplicate console handle. This fixes the unref_handle errors in
1548 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
1550 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
1553 2002-08-01 Dick Porter <dick@ximian.com>
1555 * threads.c: Use atomic spinlocks in TLS functions
1558 * Makefile.am: Added mono-spinlock.h
1560 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
1562 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
1563 these are needed for sendmsg() and also for struct msghdr (at
1564 least on Solaris). Solaris still won't build because struct msghdr
1565 doesn't have msg_flags, msg_control, or msg_controllen members.
1566 (CMSG_SPACE): Define for systems that don't have it.
1569 2002-07-20 Dick Porter <dick@ximian.com>
1575 * handles.c: Implemented pipe handles
1578 * daemon.c: Fixed bug in handle closing.
1581 * daemon.c: Forked processes now close all open file descriptors.
1583 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
1585 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
1588 2002-07-19 Martin Baulig <martin@gnome.org>
1590 * threads.c (ExitThread): Call exit() if no threads has been
1593 2002-07-17 Dick Porter <dick@ximian.com>
1595 * daemon-messages.c: Freebsd fixes from Andreas Kohn
1596 <andreas.kohn@gmx.net>
1598 2002-07-15 Dick Porter <dick@ximian.com>
1600 * io.c: Removed bogus console_flush() method, that was just cut
1601 and pasted from file_flush when I separated the two handle types.
1603 2002-07-12 Dick Porter <dick@ximian.com>
1605 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
1606 flags. Fixes bug 27633.
1608 2002-07-12 Dick Porter <dick@ximian.com>
1612 * daemon.c: Use size of sockaddr_un.sun_path from config.h
1614 2002-07-12 Dick Porter <dick@ximian.com>
1616 * processes.c (CreateProcess): Send stdin, stdout and stderr
1617 handles if the startup info doesnt specify new ones
1619 * io.c (GetStdHandle): Return the same handle when the same
1620 standard handle is requested
1622 * handles.c: Pass file descriptors when forking
1624 * daemon.c: Use supplied file descriptors when forking a new
1627 * daemon-messages.h:
1628 * daemon-messages.c: Pass stdin, stdout and stderr file
1629 descriptors to the daemon (used when forking)
1631 2002-07-11 Miguel de Icaza <miguel@ximian.com>
1633 * daemon.c (_wapi_daemon_main): Use sizeof
1634 (main_socket_address.sun_path) instead of hardcoded 108 value.
1636 * handles.c (shared_init): Use sizeof
1637 (shared_socket_address.sun_path) instead of hardcoded 108 value.
1639 2002-07-10 Dennis Haney <davh@davh.dk>
1643 * daemon.c: Lots of documentation, some added error checking, and
1644 code readability improvements.
1646 * daemon-messages.h: Add the Error request type to improve error
1649 * daemon-messages.c: Do a bit more error checking on send() and
1650 recv(), and log errors with a higher severity level.
1652 2002-07-04 Dick Porter <dick@ximian.com>
1654 * daemon.c (process_process_fork): Fix argument handling, due to
1655 buggy understanding of g_strsplit() behaviour.
1657 2002-07-03 Dick Porter <dick@ximian.com>
1660 * threads.c: Implement OpenThread(). Define access-control values
1666 * Makefile.am: Added access.h, to hold shared access-control
1669 2002-07-02 Dick Porter <dick@ximian.com>
1671 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
1673 2002-07-02 Dick Porter <dick@ximian.com>
1675 * handles.c (shared_init): Make a second attempt to contact the
1676 daemon if the shared memory attach succeeds, but the connect()
1677 fails. (This copes with the daemon crashing without cleaning up
1683 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
1684 the daemon, it's now built into the library.
1686 2002-06-25 Dick Porter <dick@ximian.com>
1689 * handles-private.h:
1690 * daemon-messages.h:
1691 * daemon.c: Process forking and handle data management
1694 * process-private.h:
1695 * processes.c: Process forking and other support functions
1697 2002-06-25 Dick Porter <dick@ximian.com>
1699 * versioninfo.h: PE resource decoding
1701 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
1702 to be told the string length
1704 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
1705 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
1708 2002-06-12 Dick Porter <dick@ximian.com>
1711 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
1712 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
1713 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
1715 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
1717 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
1718 when writing to a closed socket.
1720 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
1722 * mono-mutex.c (mono_once): New convenience function for my
1727 * critical-sections.c:
1735 * atomic.c: Use mono_once() rather than pthread_once().
1737 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
1739 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
1740 if multiple threads all try to call _wapi_handle_new() before the
1741 shared data has been initialized, it is possible that we could get
1742 into a condition where shared_init() is being executed and later
1743 threads will pass by pthread_once() due to the fact that it has
1744 already been called and so therefor will attempt to use the shared
1745 data before it has been completely initialized. If we instead use
1746 a standard mutex locking mechanism around shared_init(), we can
1747 avoid the situation entirely. By wrapping the mutex locking in a
1748 check to see if we've already initialized the data, we can even
1749 avoid wasting resources by having to lock/unlock the mutex in any
1750 later calls (the only time we'd have to worry about
1751 locking/unlocking is the initial race to call shared_init() at
1754 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
1756 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
1758 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
1760 * daemon.c, handles.c: rename "sun" local var since it's apparently
1761 a #define on Solaris.
1763 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
1765 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
1768 2002-05-15 Dick Porter <dick@ximian.com>
1770 * wait.c: Fix a deadlock in WaitForMultipleObjects
1772 2002-05-14 Dick Porter <dick@ximian.com>
1774 * io.c: Fix a cut&paste error, found by
1775 Jaroslaw Kowalski <jarek@atm.com.pl>
1777 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
1781 2002-05-09 Dick Porter <dick@ximian.com>
1787 * handles-private.h:
1789 * Makefile.am: Remove now-unused file wait-private.h
1791 2002-05-08 Dick Porter <dick@ximian.com>
1793 * shared.c: Better error messages, and report when daemon
1794 connection fails rather than blocking forever. Do some more
1795 shared memory sanity checking.
1797 * handles.c: Better error messages when connecting to shared
1798 memory and the handle daemon. Fall back to non-shared handles if
1799 an error occurs. Set the default back to 'shared handles'. Fix a
1800 crashing bug in scratch space allocation that mangled the block
1803 2002-05-07 Miguel de Icaza <miguel@ximian.com>
1805 * handles.c (shared_init): Disable SHM for now, people have too
1806 many problems with this, and the diagnostics are not helping.
1808 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
1810 * io.c: CreateFile sets win32 last error.
1812 2002-05-05 Dick Porter <dick@ximian.com>
1815 * handles-private.h:
1821 * process-private.h:
1823 * semaphore-private.h:
1827 * event-private.h: Simplify the WapiHandleOps struct: take out all
1828 the file-specific entries, leaving just the items that operate on
1829 handles themselves. Split the close operation into shared and
1830 private parts: shared close is called by the daemon.
1832 * handles.c: As above, but also pass handle allocation, ref and
1833 unref operations to the daemon. Populate the handle_ops array at
1834 compile time, because the daemon needs to call ops on handles too.
1835 Don't bother to track open handle counts any more, the daemon does
1839 * thread-private.h: As above, but also make the thread data
1842 * shared.c: Fork a handle daemon if the calling process created
1843 the shared memory segment.
1846 * daemon-messages.c:
1847 * daemon-messages.h:
1848 * Makefile.am: Build a daemon to manage handle allocation and
1849 destruction without needing to lock the shared memory
1851 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
1853 * atomic.c: Changed to use a normal mutex rather than a spinlock
1854 since a lot of platforms seem to not have them :\
1856 2002-04-30 Dick Porter <dick@ximian.com>
1858 * Completely rewrote the handle waiting code: removed the helper
1859 thread and its attendant complexity. All handle waiting is now
1860 abstracted into the WaitForSingleObject() and
1861 WaitForMultipleObjects() functions.
1863 * Implemented inter-process sharing of handles using sysv shared
1864 memory. This makes handles even more opaque, with a handle now
1865 just an index into an array.
1867 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
1869 * io.c: unitialized pointer in GetCurrentDirectory.
1871 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
1873 * threads.c: destroy the mutex at thread destruction
1874 (if/when thread destruction code will be actually called).
1875 When protecting a tls data pointer from the gc, use also the
1876 thread id in the key.
1878 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
1880 * timed-thread.c: avoid race condition when setting the thread to
1883 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1885 * jit.h: to more #include lines to avoid breaking compilation
1886 under windows when upgrading mingw and w32api to version
1889 2002-04-16 Dick Porter <dick@ximian.com>
1891 * atomic.h: Explanatory comment about lack of 80386 support
1893 2002-04-15 Dick Porter <dick@ximian.com>
1895 * atomic.h: use xaddl for InterlockedIncrement() and
1896 InterlockedDecrement(). Use cmpxchgl in a loop for
1897 InterlockedExchange() and InterlockedExchangePointer().
1899 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1901 * unicode.c: fix unicode_len() to not access uninitialized memory
1902 (and updated to conform to mono code style).
1904 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
1906 * io.c: EEXISTS is ignored for directory creation.
1907 * mono-mutex.h: remove silly "pragma }" that emacs users insert
1908 because they use a broken editor:-)
1910 2002-03-28 Dick Porter <dick@ximian.com>
1916 * handles.c: Warning cleanups
1918 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
1920 * unicode.h, unicode.c: changed to gunichar2
1921 * io.h, io.c: changed strings to gunichar2*, added
1922 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
1923 some fixes to FindFirstFile() and friends.
1925 2002-03-26 Dick Porter <dick@ximian.com>
1927 * types.h: Implement the large integer struct
1930 * timefuncs.c: Dummy functions that don't yet implement
1931 QueryPerformanceCounter() and QueryPerformanceFrequency()
1934 * threads.c: Implement SleepEx()
1937 * system.c: Beginnings of GetSystemInfo()
1939 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
1943 * context.c: Dummy function that doesnt yet implement
1947 * atomic.c: Interlocked functions
1949 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
1951 * threads.c: use a gc-safe hash table to store tls pointers.
1953 2002-03-22 Dick Porter <dick@ximian.com>
1955 * threads.c: Fix a race condition where a thread can start and
1956 exit before the handle has been properly initialised (no reason
1957 why the handle couldn't be initialised beforehand, so do so)
1959 Fix a ms to ns conversion magnitude thinko.
