1 2005-03-09 Dick Porter <dick@ximian.com>
3 * daemon.c (process_process_fork): Initialise the handle data
4 before using it in the error case. This is probably the error
5 we're working around in the previous change. Spotted by Taru Jain
6 <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.
8 2005-03-07 Dick Porter <dick@ximian.com>
10 * daemon.c: It looks like g_shell_parse_argv() can return
11 argv[0]=NULL somehow, yet still not give an error. Make sure we
12 don't pass NULL to strrchr(), working around a segfault that
13 showed up on ZLM testing.
15 2005-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
17 * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is
18 the expected error code showed by the test case in bug #73053.
20 2005-02-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
22 * io.c: another leftover.
24 Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>
26 * io.c: fixed logic in checking errno in rev 40815.
28 Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>
30 * threads.c: we don't depend on the GC checking tls
32 * processes.c: remove unused ref to GC headers.
34 Thu Feb 17 19:57:11 CET 2005 Paolo Molaro <lupus@ximian.com>
36 * io.c: remove _wapi_thread_cur_apc_pending () checks
37 when the siscall should return immediatly and handle
38 the case when a syscall is interrupted without
39 erroring out, but returning a 0 read/write if possible.
40 Still the cases of read from file need to be handled.
42 Tue Feb 8 18:28:11 CET 2005 Paolo Molaro <lupus@ximian.com>
44 * threads.c: make people test with 1 MB stack per thread.
46 2005-01-17 Dick Porter <dick@ximian.com>
48 * timefuncs.h: Make WapiFileTime endian-aware, as it's often
49 cast to and from 64bit ints. Fixes bug 71213.
51 2005-01-11 Dick Porter <dick@ximian.com>
53 * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
56 Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>
58 * atomic.h: Fix functions on s390.
60 Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>
62 * atomic.h: fix some functions on ppc (tests/interlocked.cs).
64 2005-01-10 Dick Porter <dick@ximian.com>
66 * misc.c (_wapi_calc_timeout): Guard against overflow when
67 calculating timeouts. This makes waiting with a large
68 (Int32.MaxValue) timeout not return immediately.
70 2004-12-23 Ben Maurer <bmaurer@ximian.com>
72 * io.c (io_ops): make this `const' so it is shareable (well, only
73 really shareable if it is statically linked...)
75 Mon Dec 20 11:58:33 CET 2004 Paolo Molaro <lupus@ximian.com>
77 * threads.c, threads.h: add accessor to get the pthread_key_t for
80 2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
82 * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS
83 if it exists and is not the same as 'src'.
85 2004-12-01 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
87 * atomic.h : Fix InterlockedCompareExchange for s390/s390x.
89 2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
91 * processes.c: unquote the cmd path, allow for ' or " when quoting and
92 pass the quoted program name to the daemon, otherwise the call to
93 g_shell_unquote in the daemon will break things up.
95 2004-10-14 Dick Porter <dick@ximian.com>
97 * sockets.c (_wapi_accept): Revert the previous change. We now
98 set the accepted socket to have the same blocking status as the
99 listening socket in managed code. This follows MS behaviour.
101 2004-10-14 Dick Porter <dick@ximian.com>
103 * sockets.c (_wapi_accept): On Darwin, make sure a newly
104 accept()ed socket is blocking. Fixes bug 67355, patch by
105 grompf@sublimeintervention.com.
107 2004-10-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
109 * system.c: check the number of online processors instead of the
110 existing ones. Sanitize return value if it's an error.
112 2004-10-03 Ben Maurer <bmaurer@ximian.com>
114 * system.c: Add support for getting the # of cpus.
116 2004-09-28 Dick Porter <dick@ximian.com>
118 * io.c (pipe_close_private): Fix one small typo in the last change
119 that totally hosed process creation with redirected pipes.
121 2004-09-24 Dick Porter <dick@ximian.com>
128 * handles-private.h: Cope when a file descriptor is reused while
129 the handle that thought it owned it is still referenced, instead
130 of asserting. Probably fixes bug 66479, though we've been unable
133 2004-09-09 Dick Porter <dick@ximian.com>
136 * io.c: Set error codes everywhere.
138 2004-09-06 Dick Porter <dick@ximian.com>
140 * handles.c (_wapi_handle_unref): Reset the private record's type
141 (CloseHandle): Check for a fd mapping failure, and return FALSE.
142 (_wapi_handle_process_fork): Fix long-standing bug in checking
143 handle return values. Also do the required bookkeeping with the
144 new process's handles.
146 * daemon.c: When creating a new process's handles, check whether
147 the shared space needs to be increased
149 2004-09-05 Zoltan Varga <vargaz@freemail.hu>
151 * shared.c (_wapi_shm_file): Fix leaking of filename.
153 2004-08-19 Dick Porter <dick@ximian.com>
155 * handles.c (_wapi_handle_count_signalled_handles): Fix thinko
156 introduced with the fd offset stuff: unlock handles properly when
157 backing off. Fixes the monologue hang at exit.
159 2004-08-18 Dick Porter <dick@ximian.com>
162 * io.c: Check that new fds fit in the table, return error if not
164 * daemon.c (_wapi_daemon_main):
165 * handles.c (shared_init): Have all processes agree on a size for
168 2004-08-17 Dick Porter <dick@ximian.com>
170 * daemon.c (process_new):
171 * handles.c (_wapi_handle_new_internal): Cope when the space
172 reserved for file descriptors is larger than the shared segment
173 size. Fixes the crash reported when running mono under gdb on
176 2004-08-16 Dick Porter <dick@ximian.com>
180 * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
181 error checking with passed-in file descriptors.
183 2004-08-11 Dick Porter <dick@ximian.com>
186 * io.c: Returned handle values are the file descriptor the handle
191 * daemon.c: Reserve the range of handles that can have the same
192 values as file descriptors. These won't be used, but the values
193 will be used as file, console, pipe or socket handles. The fd to
194 handle mapping is done internally and is invisible to users.
197 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
198 reserve a chunk of handle space.
200 2004-08-04 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
202 * atomic.h: add support for 64-bit S/390
204 2004-07-22 Dick Porter <dick@ximian.com>
207 * threads.c: Move the destruction of the internal thread data to
208 after the thread has been joined. Fixes bug 61418.
210 2004-07-14 Dick Porter <dick@ximian.com>
212 * wait.c (test_and_own): When not waiting for all handles to
213 become signalled, only own and return the lowest. All the
214 documentation suggests that the old way was correct, but
215 experimentation shows it actually works like this. Patch by
217 (sebastien.robitaille@croesus.com), fixes bug 61511.
219 2004-07-09 Ben Maurer <bmaurer@ximian.com>
221 * threads.c: register roots for gc
223 2004-07-08 Dick Porter <dick@ximian.com>
225 * io.c (file_seek): If there is a high 32bit offset part, make
226 sure the low part isn't sign-extended. Set error codes when
227 returning failure. Fixes bug 61131.
229 2004-07-06 Dick Porter <dick@ximian.com>
231 * io.c (file_setfiletime): Check for underflow when converting to
232 time_t values. Set error codes when returning failure. Fixes bug
235 2004-07-05 Dick Porter <dick@ximian.com>
237 * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable.
239 * daemon.c (unref_handle): Only destroy a handle if all processes
240 have released it, not just the current one. Fixes bug 60887.
242 2004-06-30 Zoltan Varga <vargaz@freemail.hu>
244 * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
247 2004-06-24 Dick Porter <dick@ximian.com>
249 * mutexes.c: Indicate when a named mutex was reused
251 2004-06-24 Dick Porter <dick@ximian.com>
253 * threads.c (SuspendThread):
254 * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a
255 while loop. See bug 58161.
257 Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro <lupus@ximian.com>
259 * io.c: don't use sharemode for on-disk file permissions: it's used
260 for shared access to the open file.
262 2004-06-22 Dick Porter <dick@ximian.com>
264 * events.c (CreateEvent): When creating an auto-reset event that
265 is initially owned, make sure the set count starts at 1.
267 2004-06-18 Dick Porter <dick@ximian.com>
270 * events.c: Auto-reset events need to release one thread for each
271 time SetEvent() is called. Fixes bug 41292.
275 * mutexes.c: Scan for mutexes that are still locked by a thread
276 when it exits. Fixes the MS demo app linked by bug 41292.
278 * wait.c (test_and_own): Make sure a handle is signalled before it
281 2004-06-16 Dick Porter <dick@ximian.com>
283 * timed-thread.c: Call the thread cleanup exit routine before taking
284 the join mutex, because this could deadlock if another thread tries
285 to join in the meantime. This fixes the hang-at-exit problem seen
288 2004-06-03 Lluis Sanchez Gual <lluis@ximian.com>
290 * threads.c: Implemented SleepEx.
291 * threads.h: Fixed SleepEx signature.
293 2004-06-03 Miguel de Icaza <miguel@ximian.com>
295 * threads.c: When running under valgrind, do not allocate too much
296 stack, as Valgrind default is 1 meg.
298 2004-05-27 Dick Porter <dick@ximian.com>
301 * io.c: Implemented LockFile() and UnlockFile()
303 2004-05-21 Dick Porter <dick@ximian.com>
305 * io.c (CreateFile): Check for existing share modes when opening
311 * daemon.c: Maintain a hash of file share modes, keying on device
312 and inode (to cope with symlinks.)
314 2004-05-20 Lluis Sanchez Gual <lluis@ximian.com>
316 * daemon-messages.c: Retry if the communication with the daemon is
317 interrupted by a signal.
318 * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped.
319 Only return an error in this case if there is something in the apc queue
320 (which means that it is an interruption requested by the "user").
321 * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as
322 true since the wait is small.
323 * shared.c: Retry write calls when interrumped by a signal.
324 * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which
325 returns TRUE if there are pending asynchronous calls (APC) for the
326 provided thread. Also added _wapi_thread_dispatch_apc_queue which calls
327 the enqueued APCs. Defined a new struct ApcInfo that holds information
328 about an enqueued APC.
329 * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same
330 as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue.
331 These last two methods call the corresponding apc methods in
332 thread-private using the provided thread handle.
333 * threads.h: Added QueueUserAPC.
334 * uglify.h: Added WapiApcProc (needed by QueueUserAPC).
335 * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and
336 WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support
337 for APCs in those two methods and also in SleepEx.
339 2004-05-17 Dick Porter <dick@ximian.com>
341 * io.c (CopyFile): Speed up. Fixes bug 57859.
343 2004-05-13 Dick Porter <dick@ximian.com>
344 * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current
345 thread doesn't own the mutex, rather than assert()ing.
347 2004-05-11 Dick Porter <dick@ximian.com>
349 * shared.c (_wapi_shm_attach): Cope when a previous daemon startup
350 attempt failed, leaving shared files that look like a daemon is
353 2004-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
356 (SetFileAttributes): don't the the exec bit if the corresponding read
359 2004-05-10 Zoltan Varga <vargaz@freemail.hu>
361 * io.c (FindFirstFile): Fix invalid free.
363 2004-05-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
365 * io.c: translate from GFileError to errno codes and don't free
366 variables right after calling mono_io_scandir, as we may overwrite
369 2004-05-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
371 * io.c: g_dir_open return ENOENT for directories on which we don't have
372 read/execute permission, while returning EPERM for anything below those.
373 So, change ENOENT by EPERM if the directory exists.
375 2004-05-07 Dick Porter <dick@ximian.com>
377 * io.c (SetFileAttributes): Don't have failed chmod()s cause a
378 "file not found" error. Fixes bug 54032.
380 2004-05-07 Dick Porter <dick@ximian.com>
382 * io.c (FindFirstFile): Comment out a windows-compatibility check
383 that breaks when directories have metachars in their names.
384 Workaround for bug 58116.
386 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
388 * io.c: fixed for FindFirstFile for empty directories. Closes
391 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
393 * processes.c: set the start time for the current process. Fixes bug
396 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
398 * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
399 * io.c: implemented scandir using glib functions.
401 2004-05-04 Dick Porter <dick@ximian.com>
403 * daemon.c (read_message): Return FALSE on error so the GSource
404 callback itself can return FALSE. Cures the infinite loop poll()
406 * shared.c: Fix some daemon startup race conditions.
408 2004-04-29 Miguel de Icaza <miguel@ximian.com>
410 * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k,
411 use the stack, do not use dynamic memory.
413 2004-04-29 Zoltan Varga <vargaz@freemail.hu>
415 * io.c: Add scandir implementation for platforms which do not have
418 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
420 * io.[ch]: implemented GetLogicalDriveStrings.
422 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
425 * sockets.c: use the field name from configure when accessing sigval
426 pointer field. Makes this work on the Mac.
428 2004-04-28 Bernie Solomon <bernard@ugsolutions.com>
430 * atomic.c: (InterlockedExchange) fix typo for
433 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
436 * sockets.c: added check for sys/aio.h.
438 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
440 * error.[ch]: added _wapi_get_win32_file_error...
441 * io.c: ... which was _wapi_get_win32_error here.
442 * sockets.c: rename the function calls here too.
444 2004-04-28 Dick Porter <dick@ximian.com>
446 * daemon-messages.c: Avoid a deadlock when a thread is killed while
447 waiting for the daemon by using a recursive mutex. Helps bug 56699.
449 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
451 * io.c: fixed leak in async_notifier().
453 * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl
456 * threads.c: removed old comment.
458 2004-04-26 David Waite <mass@akuma.org>
467 * wapi-private.h: remove comma from end of enumeration declarations
468 * status.h: cast unsigned int types to int for enum assignment
470 2004-04-26 David Waite <mass@akuma.org>
473 * timefuncs.c: declare 64-bit constants as long long types (i.e.
476 2004-04-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
478 * socket-wrappers.h: _wapi_socket == WSASocket now. Added
481 * sockets.c: new unused parameters for _wapi_socket.
483 2004-04-22 Miguel de Icaza <miguel@ximian.com>
485 * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle
486 the fact that MacOS X is a piece of junk (sem_init is *defined* in
487 the libc, but they return `not implemented').
489 2004-04-22 Dick Porter <dick@ximian.com>
492 * handles-private.h: Reference the handle when it is locked, so
493 that another thread can't blow it away while we're waiting for it
509 * critical-sections.c:
510 * atomic.c: Added pthreads cleanup handlers and error asserts
513 * handles.c: Fixed the gcc "variable might be used uninitialised"
514 warnings. They can't happen, but gcc doesn't know that
515 g_assert()s don't return.
517 Fixed the declaration of _wapi_handle_process_kill() so that it
518 expects the correct type for the pid.
520 * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that
521 hasn't been used in ages and just made the code more complex.
523 2004-04-17 Zoltan Varga <vargaz@freemail.hu>
525 * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
526 warnings. Fixes #57168.
528 2004-04-16 Dick Porter <dick@ximian.com>
530 * threads.c (Sleep): Using div(3) with a negative (when signed)
531 numerator causes the quotient to be 0 and the remainder to be the
532 numerator. This feeds a small negative value to nanosleep(3),
533 which will return immediately and cause a busy wait. Fixes bug
536 2004-04-15 Dick Porter <dick@ximian.com>
539 * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3)
540 and fnmatch(3) instead of glob(3). glob() can't cope with being
541 given filenames containing metachars. This fixes bug 40557.
543 2004-04-14 Bernie Solomon <bernard@ugsolutions.com>
545 * security.c: #warning is a GCC-ism
547 2004-04-13 Sebastien Pouliot <sebastien@ximian.com>
549 * security.c: Removed GetUserName as glib g_get_user_name does a
550 better (portability) job. Added ImpersonateLoggedOnUser and
553 2004-04-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
555 * mono-mutex.h: move pthread_mutex_timedlock declaration to...
556 * mono-mutex.c: ...here. It was causing a warning that prevented
557 libgdiplus compilation.
559 2004-04-04 Miguel de Icaza <miguel@ximian.com>
561 * security.c (GetUserName): Make it work on MacOS X
563 2004-04-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
565 * security.c: use getpwuid_r if available. This one is thread-safe.
567 2004-04-02 Sebastien Pouliot <sebastien@ximian.com>
569 * Makefile.am: Added security.c|h.
570 * security.c: New file for security related functions. Added function
571 GetUserName to fix #56144.
572 * security.h: New. Header file for security.c
573 * wapi.h: Added include for security.h
575 2004-03-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
577 * daemon-messages.h: added kill structs.
579 * daemon.c: implemented process_process_kill.
580 * handles-private.h: define process_process_kill.
581 * handles.c: implemented _wapi_handle_process_kill.
582 * processes.[ch]: implemented TerminateProcess.
584 2004-03-25 Bernie Solomon <bernard@ugsolutions.com>
586 * daemon.c (rem_fd): On solaris you seem to get an
587 error even after removing the input source so don't
588 try and rem_fd it twice.
590 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
592 * daemon.c: in process_post_mortem, If the child terminated due to the
593 receipt of a signal, the exit status must be based on WTERMSIG, since
594 WEXITSTATUS returns 0 in this case.
596 2004-03-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
598 * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.
600 2004-03-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
602 * daemon.c: only call getdtablesize () once.
603 * processes.c: wait 500 ms to check if execve failed and throw the same
604 exception as MS on failure. Fixes bug #32809.
606 2004-03-17 Bernie Solomon <bernard@ugsolutions.com>
608 * io.c (async_notifier): use "union sigval" rather
609 than sigval_t as Solaris doesn't have sigval_t
610 (which isn't in IEEE 1003.1 either).
612 2004-03-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
614 * io.c: added debug stuff and removed a few redundant lines in
617 2004-03-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
619 * io-private.h: added new fields for file structure. Declare
620 _wapi_io_add_callback.
622 * io.c: added _wapi_get_win32_error, support aio_read/write in
623 file_read/write. Implemented _wapi_io_add_callback, which is where
626 * io.h: added new fields for WapiOverlapped and typedef for the
629 * processes.c: fixed off-by-one bug when handling environment variables
632 * threads.[ch]: implemented BindIoCompletionCallback.
634 * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE.
636 2004-03-14 Zoltan Varga <vargaz@freemail.hu>
638 * socket-wrappers.h: Remove extra semicolon.
640 2004-03-03 Dave Camp <dave@ximian.com>
642 * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
643 Use a new main context.
645 2004-03-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
648 (GetFileAttributes): set the error depending on errno instead of
649 setting ERROR_FILE_NOT_FOUND always. See bug #55160.
651 2004-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
654 (CopyFile): free the buffer on error.
656 (WSAIoctl): free the buffer on error.
658 2004-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
660 * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT.
662 * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW
663 using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style.
665 2004-01-27 Bernie Solomon <bernard@ugsolutions.com>
667 * shared.c (_wapi_shm_file): add hostname
668 to shared data file names to handle NFS mounted
671 Mon Jan 26 16:15:03 CET 2004 Paolo Molaro <lupus@ximian.com>
673 * sockets.h: remove obsolete soklen_t typedef.
675 Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>
677 * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket
678 wrappers to its own non-installed header file.
680 2004-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
683 (FindFirstFile): unlock the handle if FindNextFile fails.
684 (FindNextFile): g_free a couple of pointers before retrying.
687 (WaitForMultipleObjects): if only one handle provided, use
690 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
692 * handles-private.h: (_wapi_handle_type) check
693 for segment in range before using it
695 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
697 * thread-private.h: _wapi_thread_ops is now const
700 Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>
702 * threads.c, timed-thread.c, timed-thread.h: use mach
703 semaphores on Darwin (MacOSX) since the posix ones
704 are mostly broken there (threads are not created suspended
705 and they can start executing before they are fully initialized
706 like in tests/thread-static.cs).
708 Mon Dec 22 17:18:45 CET 2003 Paolo Molaro <lupus@ximian.com>
710 * atomic.h: ppc fixes.
712 2003-12-19 Bernie Solomon <bernard@ugsolutions.com>
714 * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
717 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
719 * shared.c: (_wapi_shm_open) make scratch file
720 not have to immediately regrow to avoid remaps
721 (HPUX can't cope with these).
722 (_wapi_shm_attach) use actual size of file
723 to set scratch data_len for the creating process.
725 * handles.c: (_wapi_handle_new_internal) make
726 sure mutex & cond var are initialized even for
727 non process shared ones.
728 (_wapi_handle_unref) always call destroy
729 routines on mutex & cond var
731 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
733 * daemon.c: change channel data structure so
734 input sources are removed from glib event loop
735 properly. xsp works better on Solaris and
738 2003-12-12 Bernie Solomon <bernard@ugsolutions.com>
740 * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
741 definition with file & line number for non-GCC
744 2003-12-08 Bernie Solomon <bernard@ugsolutions.com>
746 * Makefile.am: make sure hppa_atomic.s is in distribution
748 2003-12-01 Dick Porter <dick@ximian.com>
751 * mutexes.c (CreateMutex):
752 * mutex-private.h (struct _WapiHandle_mutex):
753 * handles.c: Look up certain handle types by name, in a shared
754 namespace. Currently only mutex handles have this implemented.
757 * semaphores.c (CreateSemaphore):
758 * events.c (CreateEvent): Fix signature
760 2003-11-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
762 * io.c: don't call g_free before testing errno as it may modify it.
763 If the path exists, return an error if it's not a directory. Fixes
766 2003-11-20 Dick Porter <dick@ximian.com>
768 * io.c: Missed a little-endian UTF16 conversion. Patch from
769 Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.
771 2003-10-29 Dick Porter <dick@ximian.com>
773 * io.c (MoveFile): If the move crosses filesystems, try and fall
774 back to copy and delete. Patch from Jörg Rosenkranz
775 (JoergR@voelcker.com), fixes bug 50298.
777 2003-10-28 Dick Porter <dick@ximian.com>
779 * io.c: Use the new encoding conversion to cope with non-utf8
780 locales in filenames.
782 * processes.c: Ditto for process arguments.
784 Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro <lupus@ximian.com>
786 * atomic.h: some ppc inline asm fixes (incorrect use of labels,
787 incorrect register constraints, incorrect clobber lists).
789 2003-10-13 Bernie Solomon <bernard@ugsolutions.com>
791 * Makefile.am hppa_atomic.s: add HP 64bit
792 implementation of atomic ops
794 2003-10-13 Zoltan Varga <vargaz@freemail.hu>
796 * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
797 a conditional for platforms that don't have it.
799 2003-10-09 Bernie Solomon <bernard@ugsolutions.com>
801 * threads.c: (CreateThread) use stacksize argument
802 if non-zero - change default for 64 bits to 4Mb
804 2003-09-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
806 * sockets.c: set last error when socket creation fails. This shed some
809 2003-09-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
811 * processes.c: fixed bug #48973: we only change \ by / for the argument
812 to be used as command.
813 When getting the program name from the args, don't let the space between
816 2003-09-24 Bernie Solomon <bernard@ugsolutions.com>
818 * atomic.h atomic.c: fix sparc so lock is
819 global, increment does so and it compiles under Sun compiler.
821 2003-09-22 Bernie Solomon <bernard@ugsolutions.com>
823 * handles.c: include <string.h> directly as may
824 not be nested in <sys/un.h> like Linux
826 2003-09-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
829 (DeleteFile): call SetLastError on failure. Fix by
830 richard.torkar@htu.se (Richard Torkar). Closes bug #48222.
832 2003-09-15 Lluis Sanchez Gual <lluis@ximian.com>
834 * daemon.c: In compare_process(), discard handles already signalled.
836 2003-09-02 Dick Porter <dick@ximian.com>
838 * io.c: Work around glib brain-dead assumptions about utf8-encoded
839 filenames. Fixes bug 30781.
841 2003-08-28 Dick Porter <dick@ximian.com>
843 * critical-sections.c: Patch from Bernie Solomon
844 <bernard@ugsolutions.com> to emit a warning if locking a critical
847 2003-07-23 Dick Porter <dick@ximian.com>
850 * daemon.c (maybe_exit): Avoid the race condition when the daemon is
851 closing but another client comes along when the shared data is still
852 visible. Should fix bugs 33671 and 35213.
854 2003-07-23 Dick Porter <dick@ximian.com>
856 * handles.c: Initialise handle mutex and cond. Fix by
857 Bernie Solomon <bernard@ugsolutions.com>
859 2003-07-15 Dick Porter <dick@ximian.com>
861 * timed-thread.c (timed_thread_start_routine): Fix virtual memory
862 leak when threads quit. Fixes bug 44067.
864 Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro <lupus@ximian.com>
866 * io.c: never add write permission for group or others in
867 SetFileAttributes ().
869 2003-06-17 Dick Porter <dick@ximian.com>
871 * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
872 ignore the unsupported ones ("fixes" bug 44977).
874 2003-06-17 Lluis Sanchez Gual <lluis@ximian.com>
876 * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for
877 high ms values (there was an overflow).
879 2003-06-17 Zoltan Varga <vargaz@freemail.hu>
881 * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.
883 2003-06-11 Dick Porter <dick@ximian.com>
885 * shared.c: Fix shared directory creation. Patch from
886 Pablo Baena <pbaena@uol.com.ar>
888 2003-06-10 Dick Porter <dick@ximian.com>
890 * atomic.c: Delete the useless compile warning
892 2003-06-09 Dick Porter <dick@ximian.com>
894 * daemon.c: Lookup env as a string array. Fixes bug 44289. Also
895 make setting the process handle value in the environment actually
898 * processes.c: Pretty up the process name, if it happens to be
899 "mono" such as when another mono process forks "mono foo.exe"
901 2003-06-05 Dick Porter <dick@ximian.com>
903 * processes.c (process_set_current): Don't do an expensive handle
904 search at application startup, check the environment to see if the
905 process handle has already been created.
907 * io.c: Don't do an expensive handle search when creating stdin,
908 stdout and stderr handles, just create them all the first time one
918 * daemon.c: Support for "unlimited" number of handles and scratch
921 Speed up application startup by passing process handle in the
922 environment, rather than let the app scan all handles (which gets
923 really slow when there are more than a few thousand to check.)
925 Initialise some structs passed to syscalls, noticed by valgrind.
928 2003-05-20 Dick Porter <dick@ximian.com>
930 * io.c (FindFirstFile): Include . files in the glob. Fixes bug
933 2003-05-19 Dick Porter <dick@ximian.com>
935 * threads.c: Set the new thread's stack size to 2M. Fix needed
936 for BSD, reported by Martin Dvorak <md@9ll.cz>
938 2003-05-16 Dick Porter <dick@ximian.com>
941 * io.c: Implement GetTempPath()
943 2003-05-16 Dick Porter <dick@ximian.com>
945 * processes.c (CreateProcess): Set some error codes
947 2003-05-12 Dick Porter <dick@ximian.com>
949 * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
950 Patch from Martin Dvorak <mdvorak@ninell.cz>.
952 2003-05-10 Dick Porter <dick@ximian.com>
954 * io.c (CopyFile): Copy file mode as well as file data. Based on
955 suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
958 2003-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
960 * handles.c: don't call GC_gcollect when creating new handles.
962 2003-05-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
964 * handles.c: added some debugging code. Call GC_gcollect
965 before creating a new handle. It makes Lupus' test run smoother and
966 faster (from 62 to 83 request per second). Notice that calling
967 GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does
968 not improve nor degrade the performance, so i don't do it.
970 2003-05-02 Dick Porter <dick@ximian.com>
972 * sockets.c: Rearrange closesocket() and socket_close_private(),
973 and remember to unref the handle, so we don't leak socket handles.
974 Fix from Pelle Johnsen <pelle.johnsen@mail.dk>
976 2003-04-11 Dick Porter <dick@ximian.com>
978 * atomic.h: ARM atomic operations by Malte Hildingson
979 <tds00mahi@tellus.thn.htu.se>
981 Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>
983 * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.
985 2003-04-03 Martin Baulig <martin@ximian.com>
987 The following change is conditional to `WITH_INCLUDED_LIBGC'
988 which is not yet enabled by default.
990 * threads.c (SuspendThread, ResumeThread): Fully implemented this.
991 (gc_init): New static function; install a signal handler for
992 SIGPWR which is used to suspend threads. [FIXME: it SIGPWR
993 doesn't exist on all Unix systems, we need to find another
995 (mono_wapi_push_thread_stack): New public function. Tells the
996 garbage collector about the current stack pointer of a suspended
999 2003-04-03 Martin Baulig <martin@ximian.com>
1001 * timed-thread.h (TimedThread): Added `suspended_sem',
1002 `suspend_count' and `stack_ptr'.
1004 2003-03-28 Dick Porter <dick@ximian.com>
1006 * atomic.h: PPC support gratiously donated to the public domain
1007 by John Duncan <jddst19@mac.com>
1009 2003-03-20 Dick Porter <dick@ximian.com>
1011 * sockets.c (_wapi_connect): If connect() fails with EACCES, try
1012 setting SO_BROADCAST and connecting again. Fixes bug 39178.
1014 2003-03-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1016 * processes.c: included Jerome Laban's patch and call SetLastError when
1017 the executable is not found.
1019 2003-03-03 Dick Porter <dick@ximian.com>
1021 * io.c (CreateFile): Try opening directories readonly, so that
1022 timestamps can be adjusted. Patch by Elan Feingold
1023 <efeingold@mn.rr.com>.
1025 2003-02-25 Dick Porter <dick@ximian.com>
1027 * shared.c (_wapi_shm_attach): Return a failure code on system
1028 call errors, rather than exiting.
1030 2003-02-21 Dick Porter <dick@ximian.com>
1032 * processes.c (GetCurrentProcessId): Use the current process
1033 handle to return the process ID, as getpid() is unreliable
1034 (linuxthreads gives each thread a different pid). Fixes bug
1037 2003-02-21 Dick Porter <dick@ximian.com>
1039 * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug
1042 2003-02-11 Dick Porter <dick@ximian.com>
1045 * timefuncs.c: Added GetTickCount()
1047 2003-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1049 * error.c: added WSA_EHOSTUNREACH mapping.
1051 2003-01-26 Miguel de Icaza <miguel@ximian.com>
1053 * io.c (SetFileAttributes): This routine is not currently
1054 implemented for the general case, but I added a special case to
1055 set the executable bit on Linux.
1057 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
1059 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
1061 2003-01-08 Dick Porter <dick@ximian.com>
1063 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
1065 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
1067 * daemon.c, handles-private.h, handles.c, wapi-private.h:
1068 Check for an implementation which says it supports
1069 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
1070 defines the symbol. Defined but with a value of -1 still
1071 means that it is unsupported.
1073 2002-12-08 Martin Baulig <martin@ximian.com>
1075 * handles.c (_wapi_handle_new): Create new non-shared handles with
1076 an initial refcount of 1, not 0.
1078 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
1080 * threads.c (TlsGetValue): removed unnecessary mutex
1082 2002-11-20 Dick Porter <dick@ximian.com>
1084 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
1085 need to store their data structure too.
1087 * threads.c: Make sure the threading data is initialised wherever
1090 2002-11-15 Dick Porter <dick@ximian.com>
1092 * timed-thread.c: Removed unneeded parameters in
1093 _wapi_timed_thread_attach().
1095 * threads.c: Renamed AttachThread() to make it not look like
1096 external API. Removed unneeded parameters.
1098 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1100 * error.[ch]: added errno_to_WSA (). It displays a warning and return
1101 WSASYSCALLFAILURE if there is no error mapping for the given errno,
1103 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
1105 2002-10-31 Dick Porter <dick@ximian.com>
1108 * io.c: Define and use INVALID_FILE_ATTRIBUTES
1110 2002-10-07 Dick Porter <dick@ximian.com>
1113 * daemon.c: Use a more accurate time source for process start and
1116 2002-10-03 Dick Porter <dick@ximian.com>
1120 * threads.c: Fixes for freebsd. Make sure that mutex and condition
1121 creation and deletion happen in the process that owns them, when
1122 POSIX shared thread objects aren't supported. This breaks on
1123 freebsd, as pthread_t is a pointer to data.
1125 2002-10-02 Dick Porter <dick@ximian.com>
1127 * shared.c: Use mmap() instead of sysv shm for the shared data.
1129 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
1133 * daemon.c: mmap()ed regions survive fork, so just pass the
1134 pointer to _wapi_daemon_main instead of mapping it again.
1136 2002-10-01 Dick Porter <dick@ximian.com>
1138 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
1139 Unfortunately libgc uses the same thread suspend technique that I
1140 want to, and the two don't mix: libgc will deadlock when it tries
1141 to stop the world if a thread has already been suspended by
1142 someone else. Just do the simple suspended create rather than the
1143 general purpose thread suspension for now.
1145 * threads.c: Pass create flags to the timed_thread create call, to
1146 implement suspended thread creation. ResumeThread() partially
1147 implemented, to cope with the case where a newly created but
1148 suspended thread is launched.
1150 2002-09-30 Dick Porter <dick@ximian.com>
1152 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
1155 2002-09-27 Dick Porter <dick@ximian.com>
1157 * semaphores.c: Only include semaphore.h if it's present. Patch
1158 for BSD from jmmv@hispabsd.org (Julio Merino).
1160 2002-09-27 Dick Porter <dick@ximian.com>
1162 * processes.c: Pass environment and working directory to the
1163 daemon when forking. Don't let argv[0] be duplicated when looking
1164 for the program name. Implement EnumProcessModules (simple
1165 version for now, lsof-style later if needed), GetModuleBaseName,
1166 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
1167 aren't available on Linux).
1169 * process-private.h: Store the process name, and the working set
1173 * handles-private.h: New functions to store and retrieve an array
1174 of strings in the scratch space
1176 * daemon.c: Don't miss deleting some handles when a client exits
1177 (we used to rely on the client doing the final cleanup, but
1178 obviously if the client is no longer there the daemon has to do
1181 Process forking now sets the environment and the working
1184 * io.c: Don't confuse fd 0 with an unassigned handle struct
1186 * atomic.h: Add a google cache alternative to the msdn URL
1188 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1191 (_wapi_recvfrom): added ECONNRESET to the switch.
1193 2002-09-24 Mark Crichton <crichton@gimp.org>
1195 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
1198 2002-09-19 Mark Crichton <crichton@gimp.org>
1200 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
1201 dont have Linux's abstract filesystem for sockets.
1203 2002-09-19 Mark Crichton <crichton@gimp.org>
1205 * atomic.h: Added SPARC atomic asm code.
1206 * daemon.c, handles-private.h, handles.c, wapi-private.h:
1207 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
1208 Solaris 9, however, the code paths don't seem to work. More testing
1209 on the shared case is *really* needed.
1211 2002-09-03 Dick Porter <dick@ximian.com>
1214 * threads.c: Removed PosixKillThread(), because it's not in the
1217 2002-08-20 Dick Porter <dick@ximian.com>
1219 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
1220 multiples of 4 bytes, to keep header structures aligned. Needed
1221 for sparc, at least. (Patch from crichton@gimp.org)
1223 * handles.c: Removed 'disable_shm' variable (we've defaulted to
1224 building with shm enabled for months now)
1226 2002-08-19 Dick Porter <dick@ximian.com>
1228 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
1229 for legacy NeXT-based systems.
1231 2002-08-12 Dick Porter <dick@ximian.com>
1233 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
1234 from Joseph Wenninger <kde@jowenn.at>)
1236 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
1238 * threads.c: use fast spinlocks by default
1240 2002-08-02 Dick Porter <dick@ximian.com>
1242 * io.c (GetStdHandle): Add a handle reference when returning a
1243 duplicate console handle. This fixes the unref_handle errors in
1246 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
1248 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
1251 2002-08-01 Dick Porter <dick@ximian.com>
1253 * threads.c: Use atomic spinlocks in TLS functions
1256 * Makefile.am: Added mono-spinlock.h
1258 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
1260 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
1261 these are needed for sendmsg() and also for struct msghdr (at
1262 least on Solaris). Solaris still won't build because struct msghdr
1263 doesn't have msg_flags, msg_control, or msg_controllen members.
1264 (CMSG_SPACE): Define for systems that don't have it.
1267 2002-07-20 Dick Porter <dick@ximian.com>
1273 * handles.c: Implemented pipe handles
1276 * daemon.c: Fixed bug in handle closing.
1279 * daemon.c: Forked processes now close all open file descriptors.
1281 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>

1286 2002-07-19 Martin Baulig <martin@gnome.org>
1288 * threads.c (ExitThread): Call exit() if no threads has been
1291 2002-07-17 Dick Porter <dick@ximian.com>
1293 * daemon-messages.c: Freebsd fixes from Andreas Kohn
1294 <andreas.kohn@gmx.net>
1296 2002-07-15 Dick Porter <dick@ximian.com>
1298 * io.c: Removed bogus console_flush() method, that was just cut
1299 and pasted from file_flush when I separated the two handle types.
1301 2002-07-12 Dick Porter <dick@ximian.com>
1303 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
1304 flags. Fixes bug 27633.
1306 2002-07-12 Dick Porter <dick@ximian.com>
1310 * daemon.c: Use size of sockaddr_un.sun_path from config.h
1312 2002-07-12 Dick Porter <dick@ximian.com>
1314 * processes.c (CreateProcess): Send stdin, stdout and stderr
1315 handles if the startup info doesnt specify new ones
1317 * io.c (GetStdHandle): Return the same handle when the same
1318 standard handle is requested
1320 * handles.c: Pass file descriptors when forking
1322 * daemon.c: Use supplied file descriptors when forking a new
1325 * daemon-messages.h:
1326 * daemon-messages.c: Pass stdin, stdout and stderr file
1327 descriptors to the daemon (used when forking)
1329 2002-07-11 Miguel de Icaza <miguel@ximian.com>
1331 * daemon.c (_wapi_daemon_main): Use sizeof
1332 (main_socket_address.sun_path) instead of hardcoded 108 value.
1334 * handles.c (shared_init): Use sizeof
1335 (shared_socket_address.sun_path) instead of hardcoded 108 value.
1337 2002-07-10 Dennis Haney <davh@davh.dk>
1341 * daemon.c: Lots of documentation, some added error checking, and
1342 code readability improvements.
1344 * daemon-messages.h: Add the Error request type to improve error
1347 * daemon-messages.c: Do a bit more error checking on send() and
1348 recv(), and log errors with a higher severity level.
1350 2002-07-04 Dick Porter <dick@ximian.com>
1352 * daemon.c (process_process_fork): Fix argument handling, due to
1353 buggy understanding of g_strsplit() behaviour.
1355 2002-07-03 Dick Porter <dick@ximian.com>
1358 * threads.c: Implement OpenThread(). Define access-control values
1364 * Makefile.am: Added access.h, to hold shared access-control
1367 2002-07-02 Dick Porter <dick@ximian.com>
1369 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
1371 2002-07-02 Dick Porter <dick@ximian.com>
1373 * handles.c (shared_init): Make a second attempt to contact the
1374 daemon if the shared memory attach succeeds, but the connect()
1375 fails. (This copes with the daemon crashing without cleaning up
1381 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
1382 the daemon, it's now built into the library.
1384 2002-06-25 Dick Porter <dick@ximian.com>
1387 * handles-private.h:
1388 * daemon-messages.h:
1389 * daemon.c: Process forking and handle data management
1392 * process-private.h:
1393 * processes.c: Process forking and other support functions
1395 2002-06-25 Dick Porter <dick@ximian.com>
1397 * versioninfo.h: PE resource decoding
1399 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
1400 to be told the string length
1402 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
1403 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
1406 2002-06-12 Dick Porter <dick@ximian.com>
1409 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
1410 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
1411 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
1413 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
1415 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
1416 when writing to a closed socket.
1418 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
1420 * mono-mutex.c (mono_once): New convenience function for my
1425 * critical-sections.c:
1433 * atomic.c: Use mono_once() rather than pthread_once().
1435 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
1437 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
1438 if multiple threads all try to call _wapi_handle_new() before the
1439 shared data has been initialized, it is possible that we could get
1440 into a condition where shared_init() is being executed and later
1441 threads will pass by pthread_once() due to the fact that it has
1442 already been called and so therefor will attempt to use the shared
1443 data before it has been completely initialized. If we instead use
1444 a standard mutex locking mechanism around shared_init(), we can
1445 avoid the situation entirely. By wrapping the mutex locking in a
1446 check to see if we've already initialized the data, we can even
1447 avoid wasting resources by having to lock/unlock the mutex in any
1448 later calls (the only time we'd have to worry about
1449 locking/unlocking is the initial race to call shared_init() at
1452 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
1454 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
1456 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
1458 * daemon.c, handles.c: rename "sun" local var since it's apparently
1459 a #define on Solaris.
1461 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
1463 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
1466 2002-05-15 Dick Porter <dick@ximian.com>
1468 * wait.c: Fix a deadlock in WaitForMultipleObjects
1470 2002-05-14 Dick Porter <dick@ximian.com>
1472 * io.c: Fix a cut&paste error, found by
1473 Jaroslaw Kowalski <jarek@atm.com.pl>
1475 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
1479 2002-05-09 Dick Porter <dick@ximian.com>
1485 * handles-private.h:
1487 * Makefile.am: Remove now-unused file wait-private.h
1489 2002-05-08 Dick Porter <dick@ximian.com>
1491 * shared.c: Better error messages, and report when daemon
1492 connection fails rather than blocking forever. Do some more
1493 shared memory sanity checking.
1495 * handles.c: Better error messages when connecting to shared
1496 memory and the handle daemon. Fall back to non-shared handles if
1497 an error occurs. Set the default back to 'shared handles'. Fix a
1498 crashing bug in scratch space allocation that mangled the block
1501 2002-05-07 Miguel de Icaza <miguel@ximian.com>
1503 * handles.c (shared_init): Disable SHM for now, people have too
1504 many problems with this, and the diagnostics are not helping.
1506 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
1508 * io.c: CreateFile sets win32 last error.
1510 2002-05-05 Dick Porter <dick@ximian.com>
1513 * handles-private.h:
1519 * process-private.h:
1521 * semaphore-private.h:
1525 * event-private.h: Simplify the WapiHandleOps struct: take out all
1526 the file-specific entries, leaving just the items that operate on
1527 handles themselves. Split the close operation into shared and
1528 private parts: shared close is called by the daemon.
1530 * handles.c: As above, but also pass handle allocation, ref and
1531 unref operations to the daemon. Populate the handle_ops array at
1532 compile time, because the daemon needs to call ops on handles too.
1533 Don't bother to track open handle counts any more, the daemon does
1537 * thread-private.h: As above, but also make the thread data
1540 * shared.c: Fork a handle daemon if the calling process created
1541 the shared memory segment.
1544 * daemon-messages.c:
1545 * daemon-messages.h:
1546 * Makefile.am: Build a daemon to manage handle allocation and
1547 destruction without needing to lock the shared memory
1549 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
1551 * atomic.c: Changed to use a normal mutex rather than a spinlock
1552 since a lot of platforms seem to not have them :\
1554 2002-04-30 Dick Porter <dick@ximian.com>
1556 * Completely rewrote the handle waiting code: removed the helper
1557 thread and its attendant complexity. All handle waiting is now
1558 abstracted into the WaitForSingleObject() and
1559 WaitForMultipleObjects() functions.
1561 * Implemented inter-process sharing of handles using sysv shared
1562 memory. This makes handles even more opaque, with a handle now
1563 just an index into an array.
1565 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
1567 * io.c: unitialized pointer in GetCurrentDirectory.
1569 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
1571 * threads.c: destroy the mutex at thread destruction
1572 (if/when thread destruction code will be actually called).
1573 When protecting a tls data pointer from the gc, use also the
1574 thread id in the key.
1576 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
1578 * timed-thread.c: avoid race condition when setting the thread to
1581 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1583 * jit.h: to more #include lines to avoid breaking compilation
1584 under windows when upgrading mingw and w32api to version
1587 2002-04-16 Dick Porter <dick@ximian.com>
1589 * atomic.h: Explanatory comment about lack of 80386 support
1591 2002-04-15 Dick Porter <dick@ximian.com>
1593 * atomic.h: use xaddl for InterlockedIncrement() and
1594 InterlockedDecrement(). Use cmpxchgl in a loop for
1595 InterlockedExchange() and InterlockedExchangePointer().
1597 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1599 * unicode.c: fix unicode_len() to not access uninitialized memory
1600 (and updated to conform to mono code style).
1602 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
1604 * io.c: EEXISTS is ignored for directory creation.
1605 * mono-mutex.h: remove silly "pragma }" that emacs users insert
1606 because they use a broken editor:-)
1608 2002-03-28 Dick Porter <dick@ximian.com>
1614 * handles.c: Warning cleanups
1616 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
1618 * unicode.h, unicode.c: changed to gunichar2
1619 * io.h, io.c: changed strings to gunichar2*, added
1620 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
1621 some fixes to FindFirstFile() and friends.

1629 QueryPerformanceCounter() and QueryPerformanceFrequency()
1632 * threads.c: Implement SleepEx()
1635 * system.c: Beginnings of GetSystemInfo()
1637 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
1641 * context.c: Dummy function that doesnt yet implement
1645 * atomic.c: Interlocked functions
1647 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
1649 * threads.c: use a gc-safe hash table to store tls pointers.
1651 2002-03-22 Dick Porter <dick@ximian.com>
1653 * threads.c: Fix a race condition where a thread can start and
1654 exit before the handle has been properly initialised (no reason
1655 why the handle couldn't be initialised beforehand, so do so)
1657 Fix a ms to ns conversion magnitude thinko.
1659 2002-03-21 Dick Porter <dick@ximian.com>
1661 * semaphores.c: Fix a problem when waiting for one or more
1662 semaphores, and another semaphore is Released (all waiting
1663 semaphores assumed they were signalled)

1674 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
1676 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
1677 threads.c, io.c: added flush method to handles.

1711 arguments for the sake of portability. Implements recursive
1712 mutexes and pthread_mutex_timedlock.
1714 * critical-sections.c:
1721 * wait.c: Use the mono-mutex wrapper portability functions/macros.
1723 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
1725 2002-01-23 Dick Porter <dick@ximian.com>
