4 * shared.c: exit if semaphores can't be created (bug #80616).
6 2007-02-01 Geoff Norton <gnorton@customerdna.com>
8 * collection.c: NetBSD doesn't define PTHREAD_STACK_MIN.
10 2007-01-26 Dick Porter <dick@ximian.com>
13 * sockets.c (_wapi_getsockopt): Windows seems to not reset
14 SO_ERROR values when they're read, contrary to the documentation.
15 Fixes the new issues raised in bug 79878 (example in C showing
16 winsock behaviour attached to that bug.)
18 2007-01-15 Mark Mason <mason@broadcom.com
20 * atomic.h: add locking primitives for MIPS.
22 2007-01-11 Dick Porter <dick@ximian.com>
24 * sockets.c (_wapi_connect): Don't do the SO_BROADCAST setting
25 here, do it in managed code instead.
26 (_wapi_getsockopt): SO_RCVTIMEO and SO_SNDTIMEO use struct
27 timeval, which has a microsecond field, not milliseconds.
28 (_wapi_setsockopt): ditto.
29 (_wapi_setsockopt): Halve the SO_SNDBUF and SO_RCVBUF values on
30 Linux, as the kernel doubles whatever we set.
31 (_wapi_socket): Save socket domain, type and protocol so it can be
33 (socket_disconnect): Implement socket disconnect (closing the
34 socket, but keeping the file descriptor.)
35 (wapi_disconnectex): A basic implementation of DisconnectEx().
36 (wapi_transmitfile): A very basic implementation of
38 (WSAIoctl): Implement the SIO_GET_EXTENSION_FUNCTION_POINTER
41 * socket-private.h (struct _WapiHandle_socket): Record socket
42 domain, type and protocol info so it can be duplicated later.
44 * sockets.h (WSAID_DISCONNECTEX,WSAID_TRANSMITFILE): Structures
45 and defines needed to look up the DisconnectEx() and
46 TransmitFile() functions by GUID.
48 * error.c (errno_to_WSA): Change ETIMEDOUT mapping to
49 WSAETIMEDOUT; add EDESTADDRREQ.
51 * io-layer.h: Need mswsock.h on windows now.
53 2007-01-04 Miguel de Icaza <miguel@novell.com>
55 * io-portability.c (find_file): Fix a coverity warning (scanning
58 2006-12-31 Miguel de Icaza <miguel@novell.com>
60 * io-portability.c (find_file): Do not abort if an empty filename
61 has been passed. This fixes the case where MONO_IOMAP=all would
62 assert if Directory.Exists ("") was called.
64 Mon Dec 18 14:54:37 CET 2006 Paolo Molaro <lupus@ximian.com>
66 * processes.c: moved a free on the error path.
68 Thu Dec 14 21:42:39 CET 2006 Paolo Molaro <lupus@ximian.com>
70 * processes.c: fixed a few memory leaks when executing
73 Mon Nov 27 13:12:17 GMT 2006 Paolo Molaro <lupus@ximian.com>
75 * atomic.h: fix arm compare and exchange (bug #78500).
77 2006-11-23 Dick Porter <dick@ximian.com>
79 * process-private.h (struct _WapiHandle_process): Add 'waited'
82 * processes.c (process_wait): Check the 'waited' parameter not the
83 signalled state when testing if a process has already been waited
84 for, as the child process itself may set signalled when exiting.
87 * wapi-private.h (_WAPI_HANDLE_VERSION): Bump shared data version
89 * shared.c: Now the shared data version has been incremented we
90 can set the counter semaphore initial value correctly
92 2006-11-22 Dick Porter <dick@ximian.com>
94 * processes.c (process_wait): Cope when the background process
95 reaper gets the process we were waiting for. Special case for
96 waiting for our own process to exit. Fixes bug 77736.
98 2006-11-17 Dick Porter <dick@ximian.com>
100 * processes.c: Fix const correctness and typos that caused memory
103 2006-11-17 Miguel de Icaza <miguel@novell.com>
105 * processes.c (ShellExecuteEx): Check error after CreateProcess,
106 thanks to Dick for pointing this out.
108 2006-11-16 Miguel de Icaza <miguel@novell.com>
110 * processes.c (ShellExecuteEx): If we fail to create a process in
111 ShellExecute, then try to use the xdg-open command, and if that
112 fails, try to use the gnome-open command,
114 Refactor the code so that we do not have to duplicate all this
115 code, but instead use a ucs2-aware version of the code to do
118 2006-11-13 Dick Porter <dick@ximian.com>
120 * io.c (_wapi_stat_to_file_attributes): If the file is a symlink
121 add the FILE_ATTRIBUTE_REPARSE_POINT flag. This is an attempt to
122 follow the specs for the windows symlink support, but will
123 probably have to be reworked when I have test data from a vista
124 machine. Fixes bug 79887.
126 2006-11-11 Miguel de Icaza <miguel@novell.com>
128 * handles.c (CloseHandle): Cope here with the new value
129 INVALID_HANDLE_VALUE set on handles.
131 * processes.c (CreateProcess): Initialize the value of hThread to
132 be INVALID_HANDLE_VALUE on failure, not to be NULL. Improvement
135 2006-11-09 Dick Porter <dick@ximian.com>
137 * sockets.c (_wapi_select): Do some sanity checking on the
138 fd_sets, to avoid file descriptors > FD_SETSIZE.
139 (_wapi_FD_CLR, _wapi_FD_ISSET, _wapi_FD_SET): Avoid file
140 descriptors > FD_SETSIZE.
142 2006-10-27 Dick Porter <dick@ximian.com>
144 * io.c (GetFileAttributes): Force symlinks to directories to be
145 returned as a regular file. Fixes bug 79733.
147 2006-10-18 Miguel de Icaza <miguel@novell.com>
149 * io-portability.c (find_in_dir): First string dup, then closedir.
151 2006-10-12 Dick Porter <dick@ximian.com>
153 * processes.c (_wapi_process_reap): Unref a process handle if we
154 reaped it, found by Zoltan. Fixes bug 79286.
155 (process_wait): Don't wait again if we've already waited for a
158 2006-10-11 Sergey Tikhonov <tsv@solvo.ru>
160 * atomic.h: Fix atomic decrement.
162 * mini/cpu-alpha.md: Use native long shift insts
164 * mono/mono/mini/tramp-alpha.c: Implemented
165 mono_arch_patch_delegate_trampoline method
167 * Started work on using global registers
169 * Use byte/word memory load/store insts if cpu supports it
174 2006-10-09 Zoltan Varga <vargaz@gmail.com>
176 * handles.c (timedwait_signal_poll_cond): Add an alertable parameter, and if it
177 is FALSE, avoid busy waiting.
179 * wait.c: Add an alertable parameter to the wait routines.
181 2006-10-06 Miguel de Icaza <miguel@novell.com>
183 * io-portability.c (find_file): Rename from
184 MONO_IO_PORTABILITY_HELP to MONO_IOMAP.
186 2006-10-03 Dick Porter <dick@ximian.com>
189 * io-portability.c: Optional portability helpers and wrapped
190 system calls to try to cope with windows filenames in
193 * io.c: Use the wrapped system calls
195 2006-09-01 Zoltan Varga <vargaz@gmail.com>
197 * critical-sections.h critical-sections.c: Make Enter/LeaveCriticalSection a macro
198 since they are perf critical.
200 * atomic.h: Applied patch from Jakub Boqusz <qboosh@pld-linux.org>.
201 Add atomic ops implementation for alpha.
203 2006-08-11 Dick Porter <dick@ximian.com>
205 * processes.c (_wapi_process_reap): Avoid a deadlock by setting
206 process termination details in an outer loop, not the
207 _wapi_search_handle() one.
209 2006-08-10 Dick Porter <dick@ximian.com>
211 * threads.c (_wapi_thread_queue_apc)
212 (_wapi_thread_dispatch_apc_queue): Use a process-local mutex here
213 instead of the cross process semaphore. We already check that
214 access to the APC queue is within the owning process so there's no
215 need to protect from other processes. Avoids a global deadlock
216 when a thread is aborted while it holds the handle semaphore
218 (_wapi_thread_apc_pending): Hide an annoying message which can
219 happen if a thread handle has been blown away at process shutdown
220 while it is in an alertable wait.
222 Both problems seen while shutting down monodevelop.
224 2006-07-25 Dick Porter <dick@ximian.com>
226 * shared.c (_wapi_shm_file): Remove '/' characters from the uname
227 results. Fixes bug 78917.
229 2006-07-20 Dick Porter <dick@ximian.com>
231 * threads.c (_wapi_thread_set_termination_details): Improve the
232 test for already-disposed thread handles, and hold the lock around
233 the mutex abandoning.
235 2006-07-17 Dick Porter <dick@ximian.com>
237 * processes.c (CreateProcess): Don't change directory unless a new
238 one has been specified. Fixes bug 78751.
240 2006-07-06 Dick Porter <dick@ximian.com>
242 * io.c (_wapi_stat_to_file_attributes): Do a better job at
243 figuring out the file attributes
244 (_wapi_set_last_path_error_from_errno): New helper function to
245 turn errno into w32 error codes that handles the differences
246 between file and directory errors
247 (file_setendoffile): Try turning off the extra write used to
248 extend files, because we probably don't need it on any modern
249 platform. If it is needed though, we also need to lseek the file
251 (CreateFile): Treat character-special devices as a console handle,
252 because they can't be seeked
253 (CopyFile): If fail_if_exists is set, then the destination needs
254 to be opened with O_EXCL
255 (CopyFile): If fail_if_exists is not set and the destination
256 already exists, then we should set the ERROR_ALREADY_EXISTS error
257 even though we return success
258 (stdhandle_create): STD_INPUT_HANDLES cannot be written to
259 (GetStdHandle): Rework without using mono_once, so console handles
260 can be properly closed and reopened.
261 (mono_io_scandir): Only override errno with EACCES when the
262 directory actually exists
263 (FindFirstFile): Set ERROR_FILE_NOT_FOUND when no files are
265 (FindClose): Cope with NULL handles
266 (CreateDirectory): When the target already exists, just return an
267 error. It's the caller's job to figure out what to do.
268 (SetCurrentDirectory): Cope with a NULL path
269 (RemoveDirectory, GetFileAttributes, GetFileAttributesEx,
270 SetFileAttributes, FindFirstFile, DeleteFile, MoveFile, CopyFile,
271 CreateFile): Set path error correctly
273 * handles.c (CloseHandle): Kludge to try and cope with passing a
276 * error.h: Add NO_ERROR as an alternative to ERROR_SUCCESS
278 * uglify.h: Added some more typedefs
280 2006-07-05 Dick Porter <dick@ximian.com>
282 * io.c (GetFileAttributes, GetFileAttributesEx): Cope with
283 dangling symlinks. Fixes bug 78664.
285 2006-06-23 Dick Porter <dick@ximian.com>
287 * handles.c (handle_cleanup):
288 * threads.c: Clean up threads properly when we're forcibly
289 removing the handle entries from the shared file in
290 handle_cleanup(). Fixes bug 78241, for real this time.
292 2006-06-15 Neale Ferguson <neale@sinenomine.net>
294 * atomic.h: More tinkering with InterlockedExchange/InterlockedCompareExchange
297 2006-06-14 Neale Ferguson <neale@sinenomine.net>
299 * atomic.h: Fix atomic exchange pointer operations for s390x - these
300 were broken as they used 32-bit instructions rather than their 64-bit
303 2006-06-14 Dick Porter <dick@ximian.com>
305 * processes.c: Don't run the atexit handlers when bailing out
308 2006-06-14 Dick Porter <dick@ximian.com>
310 * wait.c: Fix stupid typo shown up by gcc 4.1.1, = not ==
318 * collection.c: Fix a bunch of signed/unsigned warnings from gcc
321 2006-06-09 Neale Ferguson <neale@sinenomine.net>
323 * atomic.h: Fix atomic operations for s390x (not really broken
324 but changed to use full 64-bit opcodes).
326 2006-05-24 Dick Porter <dick@ximian.com>
328 * processes.c (process_set_current): Don't take an extra reference
329 if we have to create our own process handle. Fixes bug 78241
332 * threads.c (_wapi_thread_signal_self): Renamed from
333 _wapi_thread_abandon_mutexes, also sets the thread state to
334 signalled and drops a reference. Called by the runtime when the
335 main thread cleans itself up.
337 * handles.c (handle_cleanup): As a last resort, unref every shared
338 handle as the process is now exiting.
340 2006-05-16 Dick Porter <dick@ximian.com>
342 * processes.c (process_set_termination_details): Unref the handle
343 when we've stored the exit details. Fixes the rest of 78241.
345 2006-05-12 Dick Porter <dick@ximian.com>
347 * threads.c: Implement pseudo handles, making GetCurrentThread()
348 match MS behaviour. Notice when attached threads exit, and unref
349 the handle. Fix usage of GetCurrentThread() in other places.
351 * handles.c (DuplicateHandle): Implement a basic form of
354 * wait.c: Fix usage of GetCurrentThread() throughout, and cope
357 2006-04-26 Miguel de Icaza <miguel@novell.com>
359 * io.c (file_close): Oops, do not use DeleteFile which expects
360 unicode, instead use unlink directly
362 Add support for the new FileOptions bits on .NET 2.0.
364 It might be good if Dick reviews these changes.
366 * io.c (file_close): If DeleteOnClose is set, then delete the file
368 (CreateFile): Do not support encryption per user.
370 If posix_fadvise exists, pass hints on sequential scan and random
371 access. Did not figure out what WRITE_THROUGH maps to.
373 2006-04-26 Dick Porter <dick@ximian.com>
375 * sockets.c (WSAIoctl): Check the output buffer is valid before
378 * handles.c (_wapi_search_handle): Set shared pointer if we find a
379 shared handle that has been already opened.
381 2006-04-21 Dick Porter <dick@ximian.com>
383 * threads.c (GetCurrentThread): Reference the handle if we return
384 an already-known thread.
386 2006-04-07 Dick Porter <dick@ximian.com>
388 * processes.c: Fix build for older glib.
390 2006-04-06 Dick Porter <dick@ximian.com>
392 * processes.c (CreateProcess): Add a reference to the child
393 process' handle, so it won't be destroyed if this process closes
394 its copy of the handle. Fixes bug 77393.
396 * processes.c (process_set_current): Fall through to creating a
397 new one if the handle lookup fails.
399 * processes.c (_wapi_process_signal_self):
400 * handles.c (handle_cleanup): The process is exiting, so set the
401 handle state for this process to signalled. This should let other
402 non-related processes wait for this handle.
404 * handles.c (_wapi_search_handle): Don't search shared handles in
407 * collection.c (collection_thread): No need to do a collection
408 scan straight away, do the waiting first.
410 2006-04-06 Dick Porter <dick@ximian.com>
412 * shared.c: Fix parameters in semctl () call.
414 2006-03-28 Zoltan Varga <vargaz@gmail.com>
416 * atomic.h atomic.c: Applied patch from David S. Miller
417 <davem@davemloft.net>: Reimplement Interlocked* primitives on sparc
418 using CAS/CASx when __GNUC__, else we will fall back to the generic
421 2006-03-27 Dick Porter <dick@ximian.com>
423 * shared.c (_wapi_shm_file_open): Break out of a loop if the
424 shared file is smaller than expected. (We loop a few times in
425 case another process is in the middle of creating the file.)
427 2006-03-22 Dick Porter <dick@ximian.com>
432 * shared.c: Delete the semaphores and shared files when the last
433 process has finished with them
435 2006-03-15 Dick Porter <dick@ximian.com>
443 * threads.c: Explicitly initialise the handle ops struct
445 2006-03-14 Dick Porter <dick@ximian.com>
450 * handles.c: Add a 'prewait' stage to the handle waiting, to give
451 waiting threads a chance to check for bogus states before
454 * mutexes.c (namedmutex_prewait): Use the prewait stage to check
455 for named mutexes that have been abandoned in a locked state (eg
456 if a process exited abnormally while owning the mutex) and
457 override it if needed.
459 2006-03-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
461 * wait.c: speed up WaitFor* when the timeout is 0.
463 2006-03-03 Dick Porter <dick@ximian.com>
465 * processes.c (ShellExecuteEx): Cope when some of the parameters
468 2006-02-27 Dick Porter <dick@ximian.com>
472 * threads.c: Comparing pthread_t with == is not portable, so use
475 Thu Feb 23 18:47:20 GMT 2006 Paolo Molaro <lupus@ximian.com>
477 * *.h, *.h: patch from Dick to make Linuxthreads systems work again.
479 2006-02-22 Dick Porter <dick@ximian.com>
482 * threads.c: There's no need to use the timed-thread support code
483 any more, as we aren't using the timed join. This greatly
484 simplifies thread setup, and fixes a memory leak (bug 77521).
486 Don't bother to store thread IDs in a hash table, use TLS instead.
487 The one case that needs to look up the handle of a different
488 thread (OpenThread()) can do the extra work itself. Fixes bug
491 * handles.c (_wapi_search_handle): Add a reference when returning
492 a private handle (shared handles are already reffed.)
494 2006-02-17 Dick Porter <dick@ximian.com>
497 * handles.c: Check handle values passed to array lookups. Fixes
500 2006-02-09 Dick Porter <dick@ximian.com>
502 * threads.c: Cope with the problems caused by attaching already
503 existing threads - they don't get the infrastructure to clean up
504 after themselves, especially the ID to handle hash. This fixes
507 2006-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
509 * shared.c: use MONO_SHARED_HOSTNAME as a substitute for gethostname()
510 when creating the shared files in the .wapi directory. Fixes bug #77371.
512 2006-02-02 Martin Baulig <martin@ximian.com>
514 * threads.c: Removed the `WITH_INCLUDED_LIBGC' section; it has
515 never been used so far.
517 * timed-thread.h (TimedThread): Removed the `stack_ptr' field; it
518 has only been used by the removed code.
520 2006-01-03 Neale Ferguson <neale@sinenomine.net>
522 * atomic.h: Correct s390x definitions and eliminate compiler warnings.
524 2006-01-03 Sebastien Pouliot <sebastien@ximian.com>
526 * io.c: Patch _wapi_stat_to_file_attributes against bug #76966, where
527 sockets could be considered as directory.
529 2005-12-23 Dick Porter <dick@ximian.com>
533 * semaphores.c: Implement OpenSemaphore
536 * mutexes.h: Implement OpenMutex
542 * event-private.h: Implement named events. Implement OpenEvent.
544 2005-12-15 Dick Porter <dick@ximian.com>
546 * processes.c (CreateProcess): The pipe-based cross-process
547 exclusion technique was trying to write NULL buffers when appname
548 was NULL (eg when coming from ShellExecuteEx,) which usually
549 succeeded even though EFAULT was returned - but sometimes it
550 failed. This meant that the child process could block forever on
551 the pipe read. Replace it with the simpler shared handle
552 semaphore protection used everywhere else. This showed up with
553 the test case in bug 76684.
555 Tue Dec 13 11:41:49 GMT 2005 Paolo Molaro <lupus@ximian.com>
557 * shared.c: fallback to private mmap when shared mmap doesn't work
560 2005-12-06 Dick Porter <dick@ximian.com>
564 * semaphore-private.h:
565 * semaphores.c: Implement named semaphores
567 2005-11-24 Dick Porter <dick@ximian.com>
569 * processes.c (GetProcessId): Implement GetProcessId()
571 2005-11-17 Dick Porter <dick@ximian.com>
574 * processes.c: Implement ShellExecuteEx as a wrapper around
577 2005-11-11 Dick Porter <dick@ximian.com>
579 * threads.c: Give mutex abandoning its own exported function, so
580 it can be called when the runtime is cleaning up.
582 * handles.c (_wapi_search_handle_namespace): Do a handle
583 collection befre starting to check namespace strings, so that any
584 stale cruft gets removed.
586 2005-11-11 Dick Porter <dick@ximian.com>
588 * threads.c: Move thread handles back into the shared space.
590 * handles.c (_wapi_handle_unref): Add support for shared handles
591 with close() handlers
593 2005-11-04 Dick Porter <dick@ximian.com>
595 * sockets.c (ioctlsocket): Use select instead of if to avoid a
596 type promotion problem on 64bit freebsd. Based on patch by Lou
597 Kamenov <kamenovl@gmail.com>, fixes bug 76447.
599 2005-11-04 Dick Porter <dick@ximian.com>
601 * io.c (file_write): Only do the file locking if
602 MONO_STRICT_IO_EMULATION is set.
604 2005-10-21 Dick Porter <dick@ximian.com>
607 * handles.c (_wapi_lookup_handle): Cope when the shared part of a
608 handle has been deleted.
609 (_wapi_handle_unref): And when the deleted shared part is pointed
610 to as a handle is deleted
612 2005-10-20 Dick Porter <dick@ximian.com>
614 * processes.c (process_set_current): If the expected process
615 handle slot doesn't contain the correct pid, create a new handle.
617 * handles.c (_wapi_search_handle): When the search doesn't find
618 anything, return failure instead of the last handle we looked at.
619 (_wapi_handle_ref, _wapi_handle_unref): Don't try to ref or unref
620 unused handles (makes tracking refcounting bugs easier.)
622 2005-10-19 Dick Porter <dick@ximian.com>
629 * collection.c (_wapi_handle_collect): Remove the shared handle
630 indirection layer, and use locking instead. Delete other
631 complexity that is no longer needed. Refcount shared handles and
632 delete them when needed, but keep the timestamps so that orphaned
633 handles will be cleaned up eventually.
635 * shared.c (_wapi_shm_file): Add processor, OS and struct size
636 info to the shared file names, to cope with dual-boot and 32/64bit
637 size issues. Fixes bug 75839.
639 * wait.c (WaitForMultipleObjectsEx): No need to distinguish
640 between shared handles and private, as the wait functions cope
641 with both together now.
643 2005-10-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
645 * io.c: removed NO_SIGPIPE macro.
646 * sockets.c: no need for MSG_NOSIGNAL or ignoring SIGPIPE.
648 2005-10-11 Dick Porter <dick@ximian.com>
650 * sockets.c (_wapi_getsockopt): Translate SO_ERROR results into
653 * error.c (errno_to_WSA): Don't return a bogus error if someone
654 asks to translate errno 0.
656 2005-10-11 Dick Porter <dick@ximian.com>
658 * handles.c: Fix several race conditions
660 2005-10-11 Miguel de Icaza <miguel@novell.com>
662 * io.c: no need to block SIGPIPE anymore, as it is ignored.
664 2005-10-05 Dick Porter <dick@ximian.com>
666 * threads.c (_wapi_thread_own_mutex, _wapi_thread_disown_mutex):
667 Keep a reference to mutexes owned by threads, so they won't be
668 destroyed prematurely. Fixes dotmsnclient crash.
670 2005-09-26 Sebastien Pouliot <sebastien@ximian.com>
672 * io.c: Apply patch from #76192 (Can't write files past 2gb on AMD64
673 (x86_64)) for Brion on IRC (Dick approved it).
675 2005-09-23 Dick Porter <dick@ximian.com>
677 * processes.c: Don't wait for processes that have already been
678 signalled; also fix typo.
680 * handles.c: Improve locking inside new handle and handle
683 2005-09-20 Dick Porter <dick@ximian.com>
686 * processes.c: Periodically waitpid for known process IDs. Fixes
689 2005-09-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
692 (CreateFile): if the file is a named pipe, treat the handle as a pipe,
693 not as a file. Fixes bug #76075.
695 2005-08-27 Zoltan Varga <vargaz@gmail.com>
697 * atomic.h: Add support for intel icc.
699 2005-08-25 Zoltan Varga <vargaz@gmail.com>
701 * io-layer.h: Include winbase.h not WinBase.h.
703 2005-08-19 Dick Porter <dick@ximian.com>
705 * threads.c, threads.h, thread-private.h: Use a gsize to store the
706 thread ID, so it can hold a 64 bit value if needed.
708 2005-07-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
710 * error.c: map ENOENT to WSAECONNREFUSED. It might happen when
711 connecting to unix sockets. Closes bug #75632.
713 2005-07-05 Dick Porter <dick@ximian.com>
715 * io.c: Make sure SIGPIPE is ignored when calling write(2).
716 Prevents the runtime exiting when writing to a closed pipe,
719 2005-06-30 Dick Porter <dick@ximian.com>
721 * shared.c (_wapi_shm_semaphores_init): Add some helpful error
722 messages when semget () fails due to lack of resources.
724 2005-06-21 Dick Porter <dick@ximian.com>
729 * threads.c: Keep a list of owned mutexes in each thread handle,
730 so that it is easier to abandon them when the thread exits.
731 Removes a bottleneck when multiple threads are finishing in
734 2005-06-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
736 * io.c: (GetLogicalDrives) when a bogus line is read, don't leak memory.
737 When the buffer has not enough space, close the file before returning.
739 2005-06-09 Duncan Mak <duncan@novell.com>
741 * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to
742 all public headers. Fixes #74919.
744 2005-05-30 Zoltan Varga <vargaz@freemail.hu>
746 * atomic.h: Add IA64 atomic ops.
748 2005-05-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>
750 * processes.c: make ExitCode be valid even if the user didn't call
751 WaitForExit() and is just polling on HasExited.
753 2005-05-17 Dick Porter <dick@ximian.com>
755 * io.c (file_getfilesize): Clear the error value, so that files
756 with sizes with the low bits 0xFFFFFFFF can be distinguished from
759 2005-05-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
761 * shared.c: forgot to ignore a warning.
763 2005-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
765 * shared.c: don't display warnings after reboots.
767 2005-05-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
769 * sockets.c: on windows, getsockopt/setsockopt for send/receive timeout
770 use an integer in milliseconds. We were using a struct timeval.
772 2005-05-06 Dick Porter <dick@ximian.com>
781 * collection.h: Use SysV semaphores for managing access to the
782 shared memory - in return for the ludicrous api we get
783 synchronisation primitives that can be cleaned up by the kernel
784 even when a process quits unexpectedly. This removes the
787 2005-05-05 Lluis Sanchez Gual <lluis@novell.com>
789 * handles.c: Always use polling in the waits, since
790 mono_cond_timedwait can't be interruped by the thread abort signal.
792 2005-04-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>
794 * events.c: calling Set on AutoResetEvent several times has the same
795 effect as calling it only once if no thread is waiting for it.
797 2005-04-29 Dick Porter <dick@ximian.com>
799 * processes.c (EnumProcesses): Use a GArray instead of a GPtrArray
800 now it's storing pids not handles, also fixes memory leak caused
801 by unclear glib documentation.
803 * sockets.c (WSACleanup): Remove unused variable
805 2005-04-29 Dick Porter <dick@ximian.com>
807 * handles.c (_wapi_handle_check_share_by_pid): For systems that
808 don't have file descriptor info in /proc check that the original
809 opener of a file is still there, if a share violation would
812 2005-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
815 * handles-private.h: added _wapi_handle_forecch that loops through all
816 the handles and call a callback function when a handle of the given
819 * sockets.c: no need to keep open sockets in an array, as we have them
820 in the handles structure.
824 2005-04-28 Dick Porter <dick@ximian.com>
826 * processes.c: Cope with handles that are only around for as long
827 as the search is running. If we're searching for process handles,
828 check to see if the process is still running and signal it if not.
830 * handles.c (_wapi_search_handle): Search in the shared space as
831 well. Fixed bug 74752.
834 * handles.c (_wapi_handle_new_from_offset):
835 _wapi_handle_new_for_existing_ns () was doing exactly the same as
838 2005-04-26 Dick Porter <dick@ximian.com>
840 * handles.c: Fix stupid thinko where if a new shared handle is
841 created but a collection was needed to free some space, it
842 returned an error anyway. Should fix the messages shown in bug
845 2005-04-25 Dick Porter <dick@ximian.com>
847 * handles.c (_wapi_handle_check_share): Only consider mono
848 processes when looking to see if a file is still being held open,
849 while checking share permissions.
851 2005-04-25 Dick Porter <dick@ximian.com>
855 * wapi-private.h (struct _WapiHandleOps):
856 * handles.c (_wapi_handle_unref): When destroying handles, save
857 the handle data and call the close function only after the array
858 slot has been cleared. This prevents race conditions with file
859 descriptors, fixing bug 74713.
861 * mutexes.c: Delete the handle close functions, they didn't do
864 * error.c (_wapi_get_win32_file_error): Add a mapping for EINTR so
865 the "Unknown error" g_warning doesn't get displayed.
867 2005-04-25 Dick Porter <dick@ximian.com>
870 * threads.c: Make thread handles process-private for now to take
871 some of the space pressure off the shared memory, while I work on
874 2005-04-21 Dick Porter <dick@ximian.com>
876 * handles.c (_wapi_handle_check_share): Make sure there is a "fd"
877 dir in /proc before blowing away handle info. Fixes bug 74649.
879 2005-04-21 Dick Porter <dick@ximian.com>
881 * wait.c (WaitForMultipleObjectsEx): Implement special waits
883 * handles.c (_wapi_handle_wait_signal_poll_share): Don't return a
884 timeout, just wait briefly for the private signals and let the
885 waiting thread test again. This prevents us missing shared
888 2005-04-21 Dick Porter <dick@ximian.com>
890 * collection.h (_WAPI_HANDLE_COLLECTION_EXPIRED_INTERVAL): Reduce
891 the time before a slot is considered too old and deleted. This is
892 a workaround while I come up with a proper fix.
894 2005-04-21 Dick Porter <dick@ximian.com>
899 * handles.c (_wapi_handle_new): Turn assertions into errors.
901 * collection.c (_wapi_handle_collect): Use symbols not magic
902 numbers for timeout values
904 2005-04-19 Dick Porter <dick@ximian.com>
908 * handles.c (_wapi_handle_count_signalled_handles)
909 * handles-private.h (_wapi_handle_shared_lock_handle): Use new
910 shared handle locks in critical sections.
912 * handles.c (_wapi_handle_new_for_existing_ns): Reuse old handles
913 if there is already one there.
915 * handles.c (_wapi_handle_ref): It was possible for a process to
916 exit before getting around to updating shared handle timestamps,
919 Tue Apr 19 16:25:47 CEST 2005 Paolo Molaro <lupus@ximian.com>
921 * threads.c: fix lookup of the thread id in the has table:
922 always use the id value, not the pointer to the id.
924 2005-04-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
926 * handles.c: fix handle returned in _wapi_handle_search_handle. Dick
929 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
931 * io-layer/sockets.c: FIONBIO with a TRUE argument means we want
932 non-blocking IO, not the other way around.
934 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
938 * handles-private.h: GetFileType wasn't checking if we have memory
939 allocated for the handle before dereferencing it. Fixes a FileStream
942 2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
946 * handles-private.h: we were calling g_renew to expand the handle array,
947 but that might move the memory and we might have pthread conditions or
948 mutexes in the original memory area that are being used. Now instead of
949 expanding an existing array, we just create new ones and keep a list of
950 them. Access to _wapi_private_handles had to be modified accordingly.
952 2005-04-15 Dick Porter <dick@ximian.com>
954 * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN
956 2005-04-14 Raja R Harinath <rharinath@novell.com>
958 * wapi-private.h: Remove reference to 'daemon-private.h'.
960 Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro <lupus@ximian.com>
962 * atomic.h: applied patch from mass@akuma.org (David Waite)
963 to fix InterlockedExchangeAdd.
964 Fixed a few other functions, including InterlockedCompareExchange()
965 which was miscompiled by gcc with optimizations enabled.
967 2005-04-13 Dick Porter <dick@ximian.com>
969 * io.c (share_check):
970 * handles.c (_wapi_handle_check_share): Refine the file check so
971 that sharing violations within the same process don't cause
974 2005-04-13 Dick Porter <dick@ximian.com>
976 * io.c (FindFirstFile): Fix bugs introduced with the merge (bug
979 2005-04-12 Dick Porter <dick@ximian.com>
981 The daemon-less io-layer. Extensive lowlevel changes in
982 handles.c, requiring some corresponding changes in other files
983 calling these functions. Private_foo structures have been
986 File descriptor handling differences account for most of the
987 changes in io.c and sockets.c.
991 * mutexes.c: Named mutexes are now a distinct type.
992 * atomic.h: Fix a PPC uninitialised variable warning.
993 * wait.c: Check conditions before waiting on a condition variable.
994 * processes.c: Handle process fork and wait without a daemon
995 (though this has the limitation of only being able to wait for
998 2005-04-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1005 * sockets.h: removed dead code that deals with async IO.
1007 2005-03-30 Zoltan Varga <vargaz@freemail.hu>
1009 * atomic.c (InterlockedIncrement): Fix fallback implementation of
1010 InterlockedIncrement and InterlockedDecrement. Fixes #74228.
1012 2005-03-29 Sebastien Pouliot <sebastien@ximian.com>
1014 * io-layer.h: Add required header files for compiling with VS.NET.
1016 2005-03-17 Miguel de Icaza <miguel@novell.com>
1018 * io.c: don't fail on NFS when there are no more locks available.
1020 2005-03-09 Dick Porter <dick@ximian.com>
1022 * error.c (_wapi_get_win32_file_error): ENFILE and EMFILE should
1023 map to ERROR_TOO_MANY_OPEN_FILES, not ERROR_NO_MORE_FILES. Fixes
1026 2005-03-09 Dick Porter <dick@ximian.com>
1028 * daemon.c (process_process_fork): Initialise the handle data
1029 before using it in the error case. This is probably the error
1030 we're working around in the previous change. Spotted by Taru Jain
1031 <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.
1033 2005-03-07 Dick Porter <dick@ximian.com>
1035 * daemon.c: It looks like g_shell_parse_argv() can return
1036 argv[0]=NULL somehow, yet still not give an error. Make sure we
1037 don't pass NULL to strrchr(), working around a segfault that
1038 showed up on ZLM testing.
1040 2005-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1042 * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is
1043 the expected error code showed by the test case in bug #73053.
1045 2005-02-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1047 * io.c: another leftover.
1049 Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1051 * io.c: fixed logic in checking errno in rev 40815.
1053 Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>
1055 * threads.c: we don't depend on the GC checking tls
1057 * processes.c: remove unused ref to GC headers.
1059 Thu Feb 17 19:57:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1061 * io.c: remove _wapi_thread_cur_apc_pending () checks
1062 when the siscall should return immediatly and handle
1063 the case when a syscall is interrupted without
1064 erroring out, but returning a 0 read/write if possible.
1065 Still the cases of read from file need to be handled.
1067 Tue Feb 8 18:28:11 CET 2005 Paolo Molaro <lupus@ximian.com>
1069 * threads.c: make people test with 1 MB stack per thread.
1071 2005-01-17 Dick Porter <dick@ximian.com>
1073 * timefuncs.h: Make WapiFileTime endian-aware, as it's often
1074 cast to and from 64bit ints. Fixes bug 71213.
1076 2005-01-11 Dick Porter <dick@ximian.com>
1078 * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
1081 Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>
1083 * atomic.h: Fix functions on s390.
1085 Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>
1087 * atomic.h: fix some functions on ppc (tests/interlocked.cs).
1089 2005-01-10 Dick Porter <dick@ximian.com>
1091 * misc.c (_wapi_calc_timeout): Guard against overflow when
1092 calculating timeouts. This makes waiting with a large
1093 (Int32.MaxValue) timeout not return immediately.
1095 2004-12-23 Ben Maurer <bmaurer@ximian.com>
1097 * io.c (io_ops): make this `const' so it is shareable (well, only
1098 really shareable if it is statically linked...)
1100 Mon Dec 20 11:58:33 CET 2004 Paolo Molaro <lupus@ximian.com>
1102 * threads.c, threads.h: add accessor to get the pthread_key_t for
1105 2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1107 * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS
1108 if it exists and is not the same as 'src'.
1110 2004-12-01 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1112 * atomic.h : Fix InterlockedCompareExchange for s390/s390x.
1114 2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1116 * processes.c: unquote the cmd path, allow for ' or " when quoting and
1117 pass the quoted program name to the daemon, otherwise the call to
1118 g_shell_unquote in the daemon will break things up.
1120 2004-10-14 Dick Porter <dick@ximian.com>
1122 * sockets.c (_wapi_accept): Revert the previous change. We now
1123 set the accepted socket to have the same blocking status as the
1124 listening socket in managed code. This follows MS behaviour.
1126 2004-10-14 Dick Porter <dick@ximian.com>
1128 * sockets.c (_wapi_accept): On Darwin, make sure a newly
1129 accept()ed socket is blocking. Fixes bug 67355, patch by
1130 grompf@sublimeintervention.com.
1132 2004-10-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1134 * system.c: check the number of online processors instead of the
1135 existing ones. Sanitize return value if it's an error.
1137 2004-10-03 Ben Maurer <bmaurer@ximian.com>
1139 * system.c: Add support for getting the # of cpus.
1141 2004-09-28 Dick Porter <dick@ximian.com>
1143 * io.c (pipe_close_private): Fix one small typo in the last change
1144 that totally hosed process creation with redirected pipes.
1146 2004-09-24 Dick Porter <dick@ximian.com>
1153 * handles-private.h: Cope when a file descriptor is reused while
1154 the handle that thought it owned it is still referenced, instead
1155 of asserting. Probably fixes bug 66479, though we've been unable
1158 2004-09-09 Dick Porter <dick@ximian.com>
1161 * io.c: Set error codes everywhere.
1163 2004-09-06 Dick Porter <dick@ximian.com>
1165 * handles.c (_wapi_handle_unref): Reset the private record's type
1166 (CloseHandle): Check for a fd mapping failure, and return FALSE.
1167 (_wapi_handle_process_fork): Fix long-standing bug in checking
1168 handle return values. Also do the required bookkeeping with the
1169 new process's handles.
1171 * daemon.c: When creating a new process's handles, check whether
1172 the shared space needs to be increased
1174 2004-09-05 Zoltan Varga <vargaz@freemail.hu>
1176 * shared.c (_wapi_shm_file): Fix leaking of filename.
1178 2004-08-19 Dick Porter <dick@ximian.com>
1180 * handles.c (_wapi_handle_count_signalled_handles): Fix thinko
1181 introduced with the fd offset stuff: unlock handles properly when
1182 backing off. Fixes the monologue hang at exit.
1184 2004-08-18 Dick Porter <dick@ximian.com>
1187 * io.c: Check that new fds fit in the table, return error if not
1189 * daemon.c (_wapi_daemon_main):
1190 * handles.c (shared_init): Have all processes agree on a size for
1193 2004-08-17 Dick Porter <dick@ximian.com>
1195 * daemon.c (process_new):
1196 * handles.c (_wapi_handle_new_internal): Cope when the space
1197 reserved for file descriptors is larger than the shared segment
1198 size. Fixes the crash reported when running mono under gdb on
1201 2004-08-16 Dick Porter <dick@ximian.com>
1205 * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
1206 error checking with passed-in file descriptors.
1208 2004-08-11 Dick Porter <dick@ximian.com>
1211 * io.c: Returned handle values are the file descriptor the handle
1215 * handles-private.h:
1216 * daemon.c: Reserve the range of handles that can have the same
1217 values as file descriptors. These won't be used, but the values
1218 will be used as file, console, pipe or socket handles. The fd to
1219 handle mapping is done internally and is invisible to users.
1222 * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
1223 reserve a chunk of handle space.
1225 2004-08-04 Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>
1227 * atomic.h: add support for 64-bit S/390
1229 2004-07-22 Dick Porter <dick@ximian.com>
1232 * threads.c: Move the destruction of the internal thread data to
1233 after the thread has been joined. Fixes bug 61418.
1235 2004-07-14 Dick Porter <dick@ximian.com>
1237 * wait.c (test_and_own): When not waiting for all handles to
1238 become signalled, only own and return the lowest. All the
1239 documentation suggests that the old way was correct, but
1240 experimentation shows it actually works like this. Patch by
1241 Sébastien Robitaille
1242 (sebastien.robitaille@croesus.com), fixes bug 61511.
1244 2004-07-09 Ben Maurer <bmaurer@ximian.com>
1246 * threads.c: register roots for gc
1248 2004-07-08 Dick Porter <dick@ximian.com>
1250 * io.c (file_seek): If there is a high 32bit offset part, make
1251 sure the low part isn't sign-extended. Set error codes when
1252 returning failure. Fixes bug 61131.
1254 2004-07-06 Dick Porter <dick@ximian.com>
1256 * io.c (file_setfiletime): Check for underflow when converting to
1257 time_t values. Set error codes when returning failure. Fixes bug
1260 2004-07-05 Dick Porter <dick@ximian.com>
1262 * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable.
1264 * daemon.c (unref_handle): Only destroy a handle if all processes
1265 have released it, not just the current one. Fixes bug 60887.
1267 2004-06-30 Zoltan Varga <vargaz@freemail.hu>
1269 * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
1270 to prevent warnings.
1272 2004-06-24 Dick Porter <dick@ximian.com>
1274 * mutexes.c: Indicate when a named mutex was reused
1276 2004-06-24 Dick Porter <dick@ximian.com>
1278 * threads.c (SuspendThread):
1279 * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a
1280 while loop. See bug 58161.
1282 Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro <lupus@ximian.com>
1284 * io.c: don't use sharemode for on-disk file permissions: it's used
1285 for shared access to the open file.
1287 2004-06-22 Dick Porter <dick@ximian.com>
1289 * events.c (CreateEvent): When creating an auto-reset event that
1290 is initially owned, make sure the set count starts at 1.
1292 2004-06-18 Dick Porter <dick@ximian.com>
1295 * events.c: Auto-reset events need to release one thread for each
1296 time SetEvent() is called. Fixes bug 41292.
1300 * mutexes.c: Scan for mutexes that are still locked by a thread
1301 when it exits. Fixes the MS demo app linked by bug 41292.
1303 * wait.c (test_and_own): Make sure a handle is signalled before it
1306 2004-06-16 Dick Porter <dick@ximian.com>
1308 * timed-thread.c: Call the thread cleanup exit routine before taking
1309 the join mutex, because this could deadlock if another thread tries
1310 to join in the meantime. This fixes the hang-at-exit problem seen
1313 2004-06-03 Lluis Sanchez Gual <lluis@ximian.com>
1315 * threads.c: Implemented SleepEx.
1316 * threads.h: Fixed SleepEx signature.
1318 2004-06-03 Miguel de Icaza <miguel@ximian.com>
1320 * threads.c: When running under valgrind, do not allocate too much
1321 stack, as Valgrind default is 1 meg.
1323 2004-05-27 Dick Porter <dick@ximian.com>
1326 * io.c: Implemented LockFile() and UnlockFile()
1328 2004-05-21 Dick Porter <dick@ximian.com>
1330 * io.c (CreateFile): Check for existing share modes when opening
1334 * handles-private.h:
1335 * daemon-messages.h:
1336 * daemon.c: Maintain a hash of file share modes, keying on device
1337 and inode (to cope with symlinks.)
1339 2004-05-20 Lluis Sanchez Gual <lluis@ximian.com>
1341 * daemon-messages.c: Retry if the communication with the daemon is
1342 interrupted by a signal.
1343 * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped.
1344 Only return an error in this case if there is something in the apc queue
1345 (which means that it is an interruption requested by the "user").
1346 * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as
1347 true since the wait is small.
1348 * shared.c: Retry write calls when interrumped by a signal.
1349 * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which
1350 returns TRUE if there are pending asynchronous calls (APC) for the
1351 provided thread. Also added _wapi_thread_dispatch_apc_queue which calls
1352 the enqueued APCs. Defined a new struct ApcInfo that holds information
1353 about an enqueued APC.
1354 * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same
1355 as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue.
1356 These last two methods call the corresponding apc methods in
1357 thread-private using the provided thread handle.
1358 * threads.h: Added QueueUserAPC.
1359 * uglify.h: Added WapiApcProc (needed by QueueUserAPC).
1360 * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and
1361 WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support
1362 for APCs in those two methods and also in SleepEx.
1364 2004-05-17 Dick Porter <dick@ximian.com>
1366 * io.c (CopyFile): Speed up. Fixes bug 57859.
1368 2004-05-13 Dick Porter <dick@ximian.com>
1369 * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current
1370 thread doesn't own the mutex, rather than assert()ing.
1372 2004-05-11 Dick Porter <dick@ximian.com>
1374 * shared.c (_wapi_shm_attach): Cope when a previous daemon startup
1375 attempt failed, leaving shared files that look like a daemon is
1378 2004-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1381 (SetFileAttributes): don't the the exec bit if the corresponding read
1384 2004-05-10 Zoltan Varga <vargaz@freemail.hu>
1386 * io.c (FindFirstFile): Fix invalid free.
1388 2004-05-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1390 * io.c: translate from GFileError to errno codes and don't free
1391 variables right after calling mono_io_scandir, as we may overwrite
1394 2004-05-08 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1396 * io.c: g_dir_open return ENOENT for directories on which we don't have
1397 read/execute permission, while returning EPERM for anything below those.
1398 So, change ENOENT by EPERM if the directory exists.
1400 2004-05-07 Dick Porter <dick@ximian.com>
1402 * io.c (SetFileAttributes): Don't have failed chmod()s cause a
1403 "file not found" error. Fixes bug 54032.
1405 2004-05-07 Dick Porter <dick@ximian.com>
1407 * io.c (FindFirstFile): Comment out a windows-compatibility check
1408 that breaks when directories have metachars in their names.
1409 Workaround for bug 58116.
1411 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1413 * io.c: fixed for FindFirstFile for empty directories. Closes
1416 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1418 * processes.c: set the start time for the current process. Fixes bug
1421 2004-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1423 * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
1424 * io.c: implemented scandir using glib functions.
1426 2004-05-04 Dick Porter <dick@ximian.com>
1428 * daemon.c (read_message): Return FALSE on error so the GSource
1429 callback itself can return FALSE. Cures the infinite loop poll()
1431 * shared.c: Fix some daemon startup race conditions.
1433 2004-04-29 Miguel de Icaza <miguel@ximian.com>
1435 * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k,
1436 use the stack, do not use dynamic memory.
1438 2004-04-29 Zoltan Varga <vargaz@freemail.hu>
1440 * io.c: Add scandir implementation for platforms which do not have
1443 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1445 * io.[ch]: implemented GetLogicalDriveStrings.
1447 2004-04-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1450 * sockets.c: use the field name from configure when accessing sigval
1451 pointer field. Makes this work on the Mac.
1453 2004-04-28 Bernie Solomon <bernard@ugsolutions.com>
1455 * atomic.c: (InterlockedExchange) fix typo for
1458 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1461 * sockets.c: added check for sys/aio.h.
1463 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1465 * error.[ch]: added _wapi_get_win32_file_error...
1466 * io.c: ... which was _wapi_get_win32_error here.
1467 * sockets.c: rename the function calls here too.
1469 2004-04-28 Dick Porter <dick@ximian.com>
1471 * daemon-messages.c: Avoid a deadlock when a thread is killed while
1472 waiting for the daemon by using a recursive mutex. Helps bug 56699.
1474 2004-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1476 * io.c: fixed leak in async_notifier().
1478 * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl
1481 * threads.c: removed old comment.
1483 2004-04-26 David Waite <mass@akuma.org>
1485 * daemon-messages.h:
1492 * wapi-private.h: remove comma from end of enumeration declarations
1493 * status.h: cast unsigned int types to int for enum assignment
1495 2004-04-26 David Waite <mass@akuma.org>
1498 * timefuncs.c: declare 64-bit constants as long long types (i.e.
1501 2004-04-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1503 * socket-wrappers.h: _wapi_socket == WSASocket now. Added
1504 WSA_FLAG_OVERLAPPED.
1506 * sockets.c: new unused parameters for _wapi_socket.
1508 2004-04-22 Miguel de Icaza <miguel@ximian.com>
1510 * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle
1511 the fact that MacOS X is a piece of junk (sem_init is *defined* in
1512 the libc, but they return `not implemented').
1514 2004-04-22 Dick Porter <dick@ximian.com>
1517 * handles-private.h: Reference the handle when it is locked, so
1518 that another thread can't blow it away while we're waiting for it
1519 to become signalled.
1530 * handles-private.h:
1533 * daemon-messages.c:
1534 * critical-sections.c:
1535 * atomic.c: Added pthreads cleanup handlers and error asserts
1538 * handles.c: Fixed the gcc "variable might be used uninitialised"
1539 warnings. They can't happen, but gcc doesn't know that
1540 g_assert()s don't return.
1542 Fixed the declaration of _wapi_handle_process_kill() so that it
1543 expects the correct type for the pid.
1545 * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that
1546 hasn't been used in ages and just made the code more complex.
1548 2004-04-17 Zoltan Varga <vargaz@freemail.hu>
1550 * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
1551 warnings. Fixes #57168.
1553 2004-04-16 Dick Porter <dick@ximian.com>
1555 * threads.c (Sleep): Using div(3) with a negative (when signed)
1556 numerator causes the quotient to be 0 and the remainder to be the
1557 numerator. This feeds a small negative value to nanosleep(3),
1558 which will return immediately and cause a busy wait. Fixes bug
1561 2004-04-15 Dick Porter <dick@ximian.com>
1564 * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3)
1565 and fnmatch(3) instead of glob(3). glob() can't cope with being
1566 given filenames containing metachars. This fixes bug 40557.
1568 2004-04-14 Bernie Solomon <bernard@ugsolutions.com>
1570 * security.c: #warning is a GCC-ism
1572 2004-04-13 Sebastien Pouliot <sebastien@ximian.com>
1574 * security.c: Removed GetUserName as glib g_get_user_name does a
1575 better (portability) job. Added ImpersonateLoggedOnUser and
1578 2004-04-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1580 * mono-mutex.h: move pthread_mutex_timedlock declaration to...
1581 * mono-mutex.c: ...here. It was causing a warning that prevented
1582 libgdiplus compilation.
1584 2004-04-04 Miguel de Icaza <miguel@ximian.com>
1586 * security.c (GetUserName): Make it work on MacOS X
1588 2004-04-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1590 * security.c: use getpwuid_r if available. This one is thread-safe.
1592 2004-04-02 Sebastien Pouliot <sebastien@ximian.com>
1594 * Makefile.am: Added security.c|h.
1595 * security.c: New file for security related functions. Added function
1596 GetUserName to fix #56144.
1597 * security.h: New. Header file for security.c
1598 * wapi.h: Added include for security.h
1600 2004-03-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1602 * daemon-messages.h: added kill structs.
1604 * daemon.c: implemented process_process_kill.
1605 * handles-private.h: define process_process_kill.
1606 * handles.c: implemented _wapi_handle_process_kill.
1607 * processes.[ch]: implemented TerminateProcess.
1609 2004-03-25 Bernie Solomon <bernard@ugsolutions.com>
1611 * daemon.c (rem_fd): On solaris you seem to get an
1612 error even after removing the input source so don't
1613 try and rem_fd it twice.
1615 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
1617 * daemon.c: in process_post_mortem, If the child terminated due to the
1618 receipt of a signal, the exit status must be based on WTERMSIG, since
1619 WEXITSTATUS returns 0 in this case.
1621 2004-03-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1623 * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.
1625 2004-03-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1627 * daemon.c: only call getdtablesize () once.
1628 * processes.c: wait 500 ms to check if execve failed and throw the same
1629 exception as MS on failure. Fixes bug #32809.
1631 2004-03-17 Bernie Solomon <bernard@ugsolutions.com>
1633 * io.c (async_notifier): use "union sigval" rather
1634 than sigval_t as Solaris doesn't have sigval_t
1635 (which isn't in IEEE 1003.1 either).
1637 2004-03-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1639 * io.c: added debug stuff and removed a few redundant lines in
1642 2004-03-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1644 * io-private.h: added new fields for file structure. Declare
1645 _wapi_io_add_callback.
1647 * io.c: added _wapi_get_win32_error, support aio_read/write in
1648 file_read/write. Implemented _wapi_io_add_callback, which is where
1651 * io.h: added new fields for WapiOverlapped and typedef for the
1654 * processes.c: fixed off-by-one bug when handling environment variables
1657 * threads.[ch]: implemented BindIoCompletionCallback.
1659 * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE.
1661 2004-03-14 Zoltan Varga <vargaz@freemail.hu>
1663 * socket-wrappers.h: Remove extra semicolon.
1665 2004-03-03 Dave Camp <dave@ximian.com>
1667 * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
1668 Use a new main context.
1670 2004-03-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1673 (GetFileAttributes): set the error depending on errno instead of
1674 setting ERROR_FILE_NOT_FOUND always. See bug #55160.
1676 2004-03-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1679 (CopyFile): free the buffer on error.
1681 (WSAIoctl): free the buffer on error.
1683 2004-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1685 * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT.
1687 * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW
1688 using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style.
1690 2004-01-27 Bernie Solomon <bernard@ugsolutions.com>
1692 * shared.c (_wapi_shm_file): add hostname
1693 to shared data file names to handle NFS mounted
1696 Mon Jan 26 16:15:03 CET 2004 Paolo Molaro <lupus@ximian.com>
1698 * sockets.h: remove obsolete soklen_t typedef.
1700 Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>
1702 * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket
1703 wrappers to its own non-installed header file.
1705 2004-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1708 (FindFirstFile): unlock the handle if FindNextFile fails.
1709 (FindNextFile): g_free a couple of pointers before retrying.
1712 (WaitForMultipleObjects): if only one handle provided, use
1713 WaitForSingleObject.
1715 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
1717 * handles-private.h: (_wapi_handle_type) check
1718 for segment in range before using it
1720 2003-12-22 Bernie Solomon <bernard@ugsolutions.com>
1722 * thread-private.h: _wapi_thread_ops is now const
1725 Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>
1727 * threads.c, timed-thread.c, timed-thread.h: use mach
1728 semaphores on Darwin (MacOSX) since the posix ones
1729 are mostly broken there (threads are not created suspended
1730 and they can start executing before they are fully initialized
1731 like in tests/thread-static.cs).
1733 Mon Dec 22 17:18:45 CET 2003 Paolo Molaro <lupus@ximian.com>
1735 * atomic.h: ppc fixes.
1737 2003-12-19 Bernie Solomon <bernard@ugsolutions.com>
1739 * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
1742 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
1744 * shared.c: (_wapi_shm_open) make scratch file
1745 not have to immediately regrow to avoid remaps
1746 (HPUX can't cope with these).
1747 (_wapi_shm_attach) use actual size of file
1748 to set scratch data_len for the creating process.
1750 * handles.c: (_wapi_handle_new_internal) make
1751 sure mutex & cond var are initialized even for
1752 non process shared ones.
1753 (_wapi_handle_unref) always call destroy
1754 routines on mutex & cond var
1756 2003-12-15 Bernie Solomon <bernard@ugsolutions.com>
1758 * daemon.c: change channel data structure so
1759 input sources are removed from glib event loop
1760 properly. xsp works better on Solaris and
1763 2003-12-12 Bernie Solomon <bernard@ugsolutions.com>
1765 * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
1766 definition with file & line number for non-GCC
1769 2003-12-08 Bernie Solomon <bernard@ugsolutions.com>
1771 * Makefile.am: make sure hppa_atomic.s is in distribution
1773 2003-12-01 Dick Porter <dick@ximian.com>
1776 * mutexes.c (CreateMutex):
1777 * mutex-private.h (struct _WapiHandle_mutex):
1778 * handles.c: Look up certain handle types by name, in a shared
1779 namespace. Currently only mutex handles have this implemented.
1782 * semaphores.c (CreateSemaphore):
1783 * events.c (CreateEvent): Fix signature
1785 2003-11-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1787 * io.c: don't call g_free before testing errno as it may modify it.
1788 If the path exists, return an error if it's not a directory. Fixes
1791 2003-11-20 Dick Porter <dick@ximian.com>
1793 * io.c: Missed a little-endian UTF16 conversion. Patch from
1794 Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.
1796 2003-10-29 Dick Porter <dick@ximian.com>
1798 * io.c (MoveFile): If the move crosses filesystems, try and fall
1799 back to copy and delete. Patch from Jörg Rosenkranz
1800 (JoergR@voelcker.com), fixes bug 50298.
1802 2003-10-28 Dick Porter <dick@ximian.com>
1804 * io.c: Use the new encoding conversion to cope with non-utf8
1805 locales in filenames.
1807 * processes.c: Ditto for process arguments.
1809 Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro <lupus@ximian.com>
1811 * atomic.h: some ppc inline asm fixes (incorrect use of labels,
1812 incorrect register constraints, incorrect clobber lists).
1814 2003-10-13 Bernie Solomon <bernard@ugsolutions.com>
1816 * Makefile.am hppa_atomic.s: add HP 64bit
1817 implementation of atomic ops
1819 2003-10-13 Zoltan Varga <vargaz@freemail.hu>
1821 * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
1822 a conditional for platforms that don't have it.
1824 2003-10-09 Bernie Solomon <bernard@ugsolutions.com>
1826 * threads.c: (CreateThread) use stacksize argument
1827 if non-zero - change default for 64 bits to 4Mb
1829 2003-09-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1831 * sockets.c: set last error when socket creation fails. This shed some
1832 light on bug #49015.
1834 2003-09-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1836 * processes.c: fixed bug #48973: we only change \ by / for the argument
1837 to be used as command.
1838 When getting the program name from the args, don't let the space between
1841 2003-09-24 Bernie Solomon <bernard@ugsolutions.com>
1843 * atomic.h atomic.c: fix sparc so lock is
1844 global, increment does so and it compiles under Sun compiler.
1846 2003-09-22 Bernie Solomon <bernard@ugsolutions.com>
1848 * handles.c: include <string.h> directly as may
1849 not be nested in <sys/un.h> like Linux
1851 2003-09-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1854 (DeleteFile): call SetLastError on failure. Fix by
1855 richard.torkar@htu.se (Richard Torkar). Closes bug #48222.
1857 2003-09-15 Lluis Sanchez Gual <lluis@ximian.com>
1859 * daemon.c: In compare_process(), discard handles already signalled.
1861 2003-09-02 Dick Porter <dick@ximian.com>
1863 * io.c: Work around glib brain-dead assumptions about utf8-encoded
1864 filenames. Fixes bug 30781.
1866 2003-08-28 Dick Porter <dick@ximian.com>
1868 * critical-sections.c: Patch from Bernie Solomon
1869 <bernard@ugsolutions.com> to emit a warning if locking a critical
1872 2003-07-23 Dick Porter <dick@ximian.com>
1875 * daemon.c (maybe_exit): Avoid the race condition when the daemon is
1876 closing but another client comes along when the shared data is still
1877 visible. Should fix bugs 33671 and 35213.
1879 2003-07-23 Dick Porter <dick@ximian.com>
1881 * handles.c: Initialise handle mutex and cond. Fix by
1882 Bernie Solomon <bernard@ugsolutions.com>
1884 2003-07-15 Dick Porter <dick@ximian.com>
1886 * timed-thread.c (timed_thread_start_routine): Fix virtual memory
1887 leak when threads quit. Fixes bug 44067.
1889 Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro <lupus@ximian.com>
1891 * io.c: never add write permission for group or others in
1892 SetFileAttributes ().
1894 2003-06-17 Dick Porter <dick@ximian.com>
1896 * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
1897 ignore the unsupported ones ("fixes" bug 44977).
1899 2003-06-17 Lluis Sanchez Gual <lluis@ximian.com>
1901 * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for
1902 high ms values (there was an overflow).
1904 2003-06-17 Zoltan Varga <vargaz@freemail.hu>
1906 * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.
1908 2003-06-11 Dick Porter <dick@ximian.com>
1910 * shared.c: Fix shared directory creation. Patch from
1911 Pablo Baena <pbaena@uol.com.ar>
1913 2003-06-10 Dick Porter <dick@ximian.com>
1915 * atomic.c: Delete the useless compile warning
1917 2003-06-09 Dick Porter <dick@ximian.com>
1919 * daemon.c: Lookup env as a string array. Fixes bug 44289. Also
1920 make setting the process handle value in the environment actually
1923 * processes.c: Pretty up the process name, if it happens to be
1924 "mono" such as when another mono process forks "mono foo.exe"
1926 2003-06-05 Dick Porter <dick@ximian.com>
1928 * processes.c (process_set_current): Don't do an expensive handle
1929 search at application startup, check the environment to see if the
1930 process handle has already been created.
1932 * io.c: Don't do an expensive handle search when creating stdin,
1933 stdout and stderr handles, just create them all the first time one
1940 * handles-private.h:
1941 * daemon-messages.h:
1943 * daemon.c: Support for "unlimited" number of handles and scratch
1946 Speed up application startup by passing process handle in the
1947 environment, rather than let the app scan all handles (which gets
1948 really slow when there are more than a few thousand to check.)
1950 Initialise some structs passed to syscalls, noticed by valgrind.
1953 2003-05-20 Dick Porter <dick@ximian.com>
1955 * io.c (FindFirstFile): Include . files in the glob. Fixes bug
1958 2003-05-19 Dick Porter <dick@ximian.com>
1960 * threads.c: Set the new thread's stack size to 2M. Fix needed
1961 for BSD, reported by Martin Dvorak <md@9ll.cz>
1963 2003-05-16 Dick Porter <dick@ximian.com>
1966 * io.c: Implement GetTempPath()
1968 2003-05-16 Dick Porter <dick@ximian.com>
1970 * processes.c (CreateProcess): Set some error codes
1972 2003-05-12 Dick Porter <dick@ximian.com>
1974 * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
1975 Patch from Martin Dvorak <mdvorak@ninell.cz>.
1977 2003-05-10 Dick Porter <dick@ximian.com>
1979 * io.c (CopyFile): Copy file mode as well as file data. Based on
1980 suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
1983 2003-05-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1985 * handles.c: don't call GC_gcollect when creating new handles.
1987 2003-05-05 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1989 * handles.c: added some debugging code. Call GC_gcollect
1990 before creating a new handle. It makes Lupus' test run smoother and
1991 faster (from 62 to 83 request per second). Notice that calling
1992 GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does
1993 not improve nor degrade the performance, so i don't do it.
1995 2003-05-02 Dick Porter <dick@ximian.com>
1997 * sockets.c: Rearrange closesocket() and socket_close_private(),
1998 and remember to unref the handle, so we don't leak socket handles.
1999 Fix from Pelle Johnsen <pelle.johnsen@mail.dk>
2001 2003-04-11 Dick Porter <dick@ximian.com>
2003 * atomic.h: ARM atomic operations by Malte Hildingson
2004 <tds00mahi@tellus.thn.htu.se>
2006 Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>
2008 * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.
2010 2003-04-03 Martin Baulig <martin@ximian.com>
2012 The following change is conditional to `WITH_INCLUDED_LIBGC'
2013 which is not yet enabled by default.
2015 * threads.c (SuspendThread, ResumeThread): Fully implemented this.
2016 (gc_init): New static function; install a signal handler for
2017 SIGPWR which is used to suspend threads. [FIXME: it SIGPWR
2018 doesn't exist on all Unix systems, we need to find another
2020 (mono_wapi_push_thread_stack): New public function. Tells the
2021 garbage collector about the current stack pointer of a suspended
2024 2003-04-03 Martin Baulig <martin@ximian.com>
2026 * timed-thread.h (TimedThread): Added `suspended_sem',
2027 `suspend_count' and `stack_ptr'.
2029 2003-03-28 Dick Porter <dick@ximian.com>
2031 * atomic.h: PPC support gratiously donated to the public domain
2032 by John Duncan <jddst19@mac.com>
2034 2003-03-20 Dick Porter <dick@ximian.com>
2036 * sockets.c (_wapi_connect): If connect() fails with EACCES, try
2037 setting SO_BROADCAST and connecting again. Fixes bug 39178.
2039 2003-03-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2041 * processes.c: included Jerome Laban's patch and call SetLastError when
2042 the executable is not found.
2044 2003-03-03 Dick Porter <dick@ximian.com>
2046 * io.c (CreateFile): Try opening directories readonly, so that
2047 timestamps can be adjusted. Patch by Elan Feingold
2048 <efeingold@mn.rr.com>.
2050 2003-02-25 Dick Porter <dick@ximian.com>
2052 * shared.c (_wapi_shm_attach): Return a failure code on system
2053 call errors, rather than exiting.
2055 2003-02-21 Dick Porter <dick@ximian.com>
2057 * processes.c (GetCurrentProcessId): Use the current process
2058 handle to return the process ID, as getpid() is unreliable
2059 (linuxthreads gives each thread a different pid). Fixes bug
2062 2003-02-21 Dick Porter <dick@ximian.com>
2064 * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug
2067 2003-02-11 Dick Porter <dick@ximian.com>
2070 * timefuncs.c: Added GetTickCount()
2072 2003-02-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2074 * error.c: added WSA_EHOSTUNREACH mapping.
2076 2003-01-26 Miguel de Icaza <miguel@ximian.com>
2078 * io.c (SetFileAttributes): This routine is not currently
2079 implemented for the general case, but I added a special case to
2080 set the executable bit on Linux.
2082 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
2084 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
2086 2003-01-08 Dick Porter <dick@ximian.com>
2088 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
2090 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
2092 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2093 Check for an implementation which says it supports
2094 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
2095 defines the symbol. Defined but with a value of -1 still
2096 means that it is unsupported.
2098 2002-12-08 Martin Baulig <martin@ximian.com>
2100 * handles.c (_wapi_handle_new): Create new non-shared handles with
2101 an initial refcount of 1, not 0.
2103 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
2105 * threads.c (TlsGetValue): removed unnecessary mutex
2107 2002-11-20 Dick Porter <dick@ximian.com>
2109 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
2110 need to store their data structure too.
2112 * threads.c: Make sure the threading data is initialised wherever
2115 2002-11-15 Dick Porter <dick@ximian.com>
2117 * timed-thread.c: Removed unneeded parameters in
2118 _wapi_timed_thread_attach().
2120 * threads.c: Renamed AttachThread() to make it not look like
2121 external API. Removed unneeded parameters.
2123 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2125 * error.[ch]: added errno_to_WSA (). It displays a warning and return
2126 WSASYSCALLFAILURE if there is no error mapping for the given errno,
2128 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
2130 2002-10-31 Dick Porter <dick@ximian.com>
2133 * io.c: Define and use INVALID_FILE_ATTRIBUTES
2135 2002-10-07 Dick Porter <dick@ximian.com>
2138 * daemon.c: Use a more accurate time source for process start and
2141 2002-10-03 Dick Porter <dick@ximian.com>
2145 * threads.c: Fixes for freebsd. Make sure that mutex and condition
2146 creation and deletion happen in the process that owns them, when
2147 POSIX shared thread objects aren't supported. This breaks on
2148 freebsd, as pthread_t is a pointer to data.
2150 2002-10-02 Dick Porter <dick@ximian.com>
2152 * shared.c: Use mmap() instead of sysv shm for the shared data.
2154 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
2158 * daemon.c: mmap()ed regions survive fork, so just pass the
2159 pointer to _wapi_daemon_main instead of mapping it again.
2161 2002-10-01 Dick Porter <dick@ximian.com>
2163 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
2164 Unfortunately libgc uses the same thread suspend technique that I
2165 want to, and the two don't mix: libgc will deadlock when it tries
2166 to stop the world if a thread has already been suspended by
2167 someone else. Just do the simple suspended create rather than the
2168 general purpose thread suspension for now.
2170 * threads.c: Pass create flags to the timed_thread create call, to
2171 implement suspended thread creation. ResumeThread() partially
2172 implemented, to cope with the case where a newly created but
2173 suspended thread is launched.
2175 2002-09-30 Dick Porter <dick@ximian.com>
2177 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
2180 2002-09-27 Dick Porter <dick@ximian.com>
2182 * semaphores.c: Only include semaphore.h if it's present. Patch
2183 for BSD from jmmv@hispabsd.org (Julio Merino).
2185 2002-09-27 Dick Porter <dick@ximian.com>
2187 * processes.c: Pass environment and working directory to the
2188 daemon when forking. Don't let argv[0] be duplicated when looking
2189 for the program name. Implement EnumProcessModules (simple
2190 version for now, lsof-style later if needed), GetModuleBaseName,
2191 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
2192 aren't available on Linux).
2194 * process-private.h: Store the process name, and the working set
2198 * handles-private.h: New functions to store and retrieve an array
2199 of strings in the scratch space
2201 * daemon.c: Don't miss deleting some handles when a client exits
2202 (we used to rely on the client doing the final cleanup, but
2203 obviously if the client is no longer there the daemon has to do
2206 Process forking now sets the environment and the working
2209 * io.c: Don't confuse fd 0 with an unassigned handle struct
2211 * atomic.h: Add a google cache alternative to the msdn URL
2213 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2216 (_wapi_recvfrom): added ECONNRESET to the switch.
2218 2002-09-24 Mark Crichton <crichton@gimp.org>
2220 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
2223 2002-09-19 Mark Crichton <crichton@gimp.org>
2225 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
2226 dont have Linux's abstract filesystem for sockets.
2228 2002-09-19 Mark Crichton <crichton@gimp.org>
2230 * atomic.h: Added SPARC atomic asm code.
2231 * daemon.c, handles-private.h, handles.c, wapi-private.h:
2232 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
2233 Solaris 9, however, the code paths don't seem to work. More testing
2234 on the shared case is *really* needed.
2236 2002-09-03 Dick Porter <dick@ximian.com>
2239 * threads.c: Removed PosixKillThread(), because it's not in the
2242 2002-08-20 Dick Porter <dick@ximian.com>
2244 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
2245 multiples of 4 bytes, to keep header structures aligned. Needed
2246 for sparc, at least. (Patch from crichton@gimp.org)
2248 * handles.c: Removed 'disable_shm' variable (we've defaulted to
2249 building with shm enabled for months now)
2251 2002-08-19 Dick Porter <dick@ximian.com>
2253 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
2254 for legacy NeXT-based systems.
2256 2002-08-12 Dick Porter <dick@ximian.com>
2258 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
2259 from Joseph Wenninger <kde@jowenn.at>)
2261 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
2263 * threads.c: use fast spinlocks by default
2265 2002-08-02 Dick Porter <dick@ximian.com>
2267 * io.c (GetStdHandle): Add a handle reference when returning a
2268 duplicate console handle. This fixes the unref_handle errors in
2271 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
2273 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
2276 2002-08-01 Dick Porter <dick@ximian.com>
2278 * threads.c: Use atomic spinlocks in TLS functions
2281 * Makefile.am: Added mono-spinlock.h
2283 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
2285 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
2286 these are needed for sendmsg() and also for struct msghdr (at
2287 least on Solaris). Solaris still won't build because struct msghdr
2288 doesn't have msg_flags, msg_control, or msg_controllen members.
2289 (CMSG_SPACE): Define for systems that don't have it.
2292 2002-07-20 Dick Porter <dick@ximian.com>
2298 * handles.c: Implemented pipe handles
2301 * daemon.c: Fixed bug in handle closing.
2304 * daemon.c: Forked processes now close all open file descriptors.
2306 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
2308 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
2311 2002-07-19 Martin Baulig <martin@gnome.org>
2313 * threads.c (ExitThread): Call exit() if no threads has been
2316 2002-07-17 Dick Porter <dick@ximian.com>
2318 * daemon-messages.c: Freebsd fixes from Andreas Kohn
2319 <andreas.kohn@gmx.net>
2321 2002-07-15 Dick Porter <dick@ximian.com>
2323 * io.c: Removed bogus console_flush() method, that was just cut
2324 and pasted from file_flush when I separated the two handle types.
2326 2002-07-12 Dick Porter <dick@ximian.com>
2328 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
2329 flags. Fixes bug 27633.
2331 2002-07-12 Dick Porter <dick@ximian.com>
2335 * daemon.c: Use size of sockaddr_un.sun_path from config.h
2337 2002-07-12 Dick Porter <dick@ximian.com>
2339 * processes.c (CreateProcess): Send stdin, stdout and stderr
2340 handles if the startup info doesnt specify new ones
2342 * io.c (GetStdHandle): Return the same handle when the same
2343 standard handle is requested
2345 * handles.c: Pass file descriptors when forking
2347 * daemon.c: Use supplied file descriptors when forking a new
2350 * daemon-messages.h:
2351 * daemon-messages.c: Pass stdin, stdout and stderr file
2352 descriptors to the daemon (used when forking)
2354 2002-07-11 Miguel de Icaza <miguel@ximian.com>
2356 * daemon.c (_wapi_daemon_main): Use sizeof
2357 (main_socket_address.sun_path) instead of hardcoded 108 value.
2359 * handles.c (shared_init): Use sizeof
2360 (shared_socket_address.sun_path) instead of hardcoded 108 value.
2362 2002-07-10 Dennis Haney <davh@davh.dk>
2366 * daemon.c: Lots of documentation, some added error checking, and
2367 code readability improvements.
2369 * daemon-messages.h: Add the Error request type to improve error
2372 * daemon-messages.c: Do a bit more error checking on send() and
2373 recv(), and log errors with a higher severity level.
2375 2002-07-04 Dick Porter <dick@ximian.com>
2377 * daemon.c (process_process_fork): Fix argument handling, due to
2378 buggy understanding of g_strsplit() behaviour.
2380 2002-07-03 Dick Porter <dick@ximian.com>
2383 * threads.c: Implement OpenThread(). Define access-control values
2389 * Makefile.am: Added access.h, to hold shared access-control
2392 2002-07-02 Dick Porter <dick@ximian.com>
2394 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
2396 2002-07-02 Dick Porter <dick@ximian.com>
2398 * handles.c (shared_init): Make a second attempt to contact the
2399 daemon if the shared memory attach succeeds, but the connect()
2400 fails. (This copes with the daemon crashing without cleaning up
2406 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
2407 the daemon, it's now built into the library.
2409 2002-06-25 Dick Porter <dick@ximian.com>
2412 * handles-private.h:
2413 * daemon-messages.h:
2414 * daemon.c: Process forking and handle data management
2417 * process-private.h:
2418 * processes.c: Process forking and other support functions
2420 2002-06-25 Dick Porter <dick@ximian.com>
2422 * versioninfo.h: PE resource decoding
2424 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
2425 to be told the string length
2427 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
2428 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
2431 2002-06-12 Dick Porter <dick@ximian.com>
2434 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
2435 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
2436 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
2438 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
2440 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
2441 when writing to a closed socket.
2443 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
2445 * mono-mutex.c (mono_once): New convenience function for my
2450 * critical-sections.c:
2458 * atomic.c: Use mono_once() rather than pthread_once().
2460 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
2462 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
2463 if multiple threads all try to call _wapi_handle_new() before the
2464 shared data has been initialized, it is possible that we could get
2465 into a condition where shared_init() is being executed and later
2466 threads will pass by pthread_once() due to the fact that it has
2467 already been called and so therefor will attempt to use the shared
2468 data before it has been completely initialized. If we instead use
2469 a standard mutex locking mechanism around shared_init(), we can
2470 avoid the situation entirely. By wrapping the mutex locking in a
2471 check to see if we've already initialized the data, we can even
2472 avoid wasting resources by having to lock/unlock the mutex in any
2473 later calls (the only time we'd have to worry about
2474 locking/unlocking is the initial race to call shared_init() at
2477 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
2479 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
2481 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
2483 * daemon.c, handles.c: rename "sun" local var since it's apparently
2484 a #define on Solaris.
2486 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
2488 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
2491 2002-05-15 Dick Porter <dick@ximian.com>
2493 * wait.c: Fix a deadlock in WaitForMultipleObjects
2495 2002-05-14 Dick Porter <dick@ximian.com>
2497 * io.c: Fix a cut&paste error, found by
2498 Jaroslaw Kowalski <jarek@atm.com.pl>
2500 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
2504 2002-05-09 Dick Porter <dick@ximian.com>
2510 * handles-private.h:
2512 * Makefile.am: Remove now-unused file wait-private.h
2514 2002-05-08 Dick Porter <dick@ximian.com>
2516 * shared.c: Better error messages, and report when daemon
2517 connection fails rather than blocking forever. Do some more
2518 shared memory sanity checking.
2520 * handles.c: Better error messages when connecting to shared
2521 memory and the handle daemon. Fall back to non-shared handles if
2522 an error occurs. Set the default back to 'shared handles'. Fix a
2523 crashing bug in scratch space allocation that mangled the block
2526 2002-05-07 Miguel de Icaza <miguel@ximian.com>
2528 * handles.c (shared_init): Disable SHM for now, people have too
2529 many problems with this, and the diagnostics are not helping.
2531 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
2533 * io.c: CreateFile sets win32 last error.
2535 2002-05-05 Dick Porter <dick@ximian.com>
2538 * handles-private.h:
2544 * process-private.h:
2546 * semaphore-private.h:
2550 * event-private.h: Simplify the WapiHandleOps struct: take out all
2551 the file-specific entries, leaving just the items that operate on
2552 handles themselves. Split the close operation into shared and
2553 private parts: shared close is called by the daemon.
2555 * handles.c: As above, but also pass handle allocation, ref and
2556 unref operations to the daemon. Populate the handle_ops array at
2557 compile time, because the daemon needs to call ops on handles too.
2558 Don't bother to track open handle counts any more, the daemon does
2562 * thread-private.h: As above, but also make the thread data
2565 * shared.c: Fork a handle daemon if the calling process created
2566 the shared memory segment.
2569 * daemon-messages.c:
2570 * daemon-messages.h:
2571 * Makefile.am: Build a daemon to manage handle allocation and
2572 destruction without needing to lock the shared memory
2574 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
2576 * atomic.c: Changed to use a normal mutex rather than a spinlock
2577 since a lot of platforms seem to not have them :\
2579 2002-04-30 Dick Porter <dick@ximian.com>
2581 * Completely rewrote the handle waiting code: removed the helper
2582 thread and its attendant complexity. All handle waiting is now
2583 abstracted into the WaitForSingleObject() and
2584 WaitForMultipleObjects() functions.
2586 * Implemented inter-process sharing of handles using sysv shared
2587 memory. This makes handles even more opaque, with a handle now
2588 just an index into an array.
2590 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
2592 * io.c: unitialized pointer in GetCurrentDirectory.
2594 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
2596 * threads.c: destroy the mutex at thread destruction
2597 (if/when thread destruction code will be actually called).

2676 2002-03-22 Dick Porter <dick@ximian.com>
2678 * threads.c: Fix a race condition where a thread can start and
2679 exit before the handle has been properly initialised (no reason
2680 why the handle couldn't be initialised beforehand, so do so)

2684 2002-03-21 Dick Porter <dick@ximian.com>
2686 * semaphores.c: Fix a problem when waiting for one or more
