1 2003-01-26 Miguel de Icaza <miguel@ximian.com>
3 * io.c (SetFileAttributes): This routine is not currently
4 implemented for the general case, but I added a special case to
5 set the executable bit on Linux.
7 Wed Jan 15 15:55:40 CET 2003 Paolo Molaro <lupus@ximian.com>
9 * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.
11 2003-01-08 Dick Porter <dick@ximian.com>
13 * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)
15 2002-12-11 Juli Mallett <jmallett@FreeBSD.org>
17 * daemon.c, handles-private.h, handles.c, wapi-private.h:
18 Check for an implementation which says it supports
19 _POSIX_THREAD_PROCESS_SHARED, rather than just one that
20 defines the symbol. Defined but with a value of -1 still
21 means that it is unsupported.
23 2002-12-08 Martin Baulig <martin@ximian.com>
25 * handles.c (_wapi_handle_new): Create new non-shared handles with
26 an initial refcount of 1, not 0.
28 2002-11-22 Dietmar Maurer <dietmar@ximian.com>
30 * threads.c (TlsGetValue): removed unnecessary mutex
32 2002-11-20 Dick Porter <dick@ximian.com>
34 * timed-thread.c (_wapi_timed_thread_attach): Attached threads
35 need to store their data structure too.
37 * threads.c: Make sure the threading data is initialised wherever
40 2002-11-15 Dick Porter <dick@ximian.com>
42 * timed-thread.c: Removed unneeded parameters in
43 _wapi_timed_thread_attach().
45 * threads.c: Renamed AttachThread() to make it not look like
46 external API. Removed unneeded parameters.
48 2002-11-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
50 * error.[ch]: added errno_to_WSA (). It displays a warning and return
51 WSASYSCALLFAILURE if there is no error mapping for the given errno,
53 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
55 2002-10-31 Dick Porter <dick@ximian.com>
58 * io.c: Define and use INVALID_FILE_ATTRIBUTES
60 2002-10-07 Dick Porter <dick@ximian.com>
63 * daemon.c: Use a more accurate time source for process start and
66 2002-10-03 Dick Porter <dick@ximian.com>
70 * threads.c: Fixes for freebsd. Make sure that mutex and condition
71 creation and deletion happen in the process that owns them, when
72 POSIX shared thread objects aren't supported. This breaks on
73 freebsd, as pthread_t is a pointer to data.
75 2002-10-02 Dick Porter <dick@ximian.com>
77 * shared.c: Use mmap() instead of sysv shm for the shared data.
79 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
83 * daemon.c: mmap()ed regions survive fork, so just pass the
84 pointer to _wapi_daemon_main instead of mapping it again.
86 2002-10-01 Dick Porter <dick@ximian.com>
88 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
89 Unfortunately libgc uses the same thread suspend technique that I
90 want to, and the two don't mix: libgc will deadlock when it tries
91 to stop the world if a thread has already been suspended by
92 someone else. Just do the simple suspended create rather than the
93 general purpose thread suspension for now.
95 * threads.c: Pass create flags to the timed_thread create call, to
96 implement suspended thread creation. ResumeThread() partially
97 implemented, to cope with the case where a newly created but
98 suspended thread is launched.
100 2002-09-30 Dick Porter <dick@ximian.com>
102 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
105 2002-09-27 Dick Porter <dick@ximian.com>
107 * semaphores.c: Only include semaphore.h if it's present. Patch
108 for BSD from jmmv@hispabsd.org (Julio Merino).
110 2002-09-27 Dick Porter <dick@ximian.com>
112 * processes.c: Pass environment and working directory to the
113 daemon when forking. Don't let argv[0] be duplicated when looking
114 for the program name. Implement EnumProcessModules (simple
115 version for now, lsof-style later if needed), GetModuleBaseName,
116 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
117 aren't available on Linux).
119 * process-private.h: Store the process name, and the working set
123 * handles-private.h: New functions to store and retrieve an array
124 of strings in the scratch space
126 * daemon.c: Don't miss deleting some handles when a client exits
127 (we used to rely on the client doing the final cleanup, but
128 obviously if the client is no longer there the daemon has to do
131 Process forking now sets the environment and the working
134 * io.c: Don't confuse fd 0 with an unassigned handle struct
136 * atomic.h: Add a google cache alternative to the msdn URL
138 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
141 (_wapi_recvfrom): added ECONNRESET to the switch.
143 2002-09-24 Mark Crichton <crichton@gimp.org>
145 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
148 2002-09-19 Mark Crichton <crichton@gimp.org>
150 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
151 dont have Linux's abstract filesystem for sockets.
153 2002-09-19 Mark Crichton <crichton@gimp.org>
155 * atomic.h: Added SPARC atomic asm code.
156 * daemon.c, handles-private.h, handles.c, wapi-private.h:
157 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
158 Solaris 9, however, the code paths don't seem to work. More testing
159 on the shared case is *really* needed.
161 2002-09-03 Dick Porter <dick@ximian.com>
164 * threads.c: Removed PosixKillThread(), because it's not in the
167 2002-08-20 Dick Porter <dick@ximian.com>
169 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
170 multiples of 4 bytes, to keep header structures aligned. Needed
171 for sparc, at least. (Patch from crichton@gimp.org)
173 * handles.c: Removed 'disable_shm' variable (we've defaulted to
174 building with shm enabled for months now)
176 2002-08-19 Dick Porter <dick@ximian.com>
178 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
179 for legacy NeXT-based systems.
181 2002-08-12 Dick Porter <dick@ximian.com>
183 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
184 from Joseph Wenninger <kde@jowenn.at>)
186 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
188 * threads.c: use fast spinlocks by default
190 2002-08-02 Dick Porter <dick@ximian.com>
192 * io.c (GetStdHandle): Add a handle reference when returning a
193 duplicate console handle. This fixes the unref_handle errors in
196 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
198 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
201 2002-08-01 Dick Porter <dick@ximian.com>
203 * threads.c: Use atomic spinlocks in TLS functions
206 * Makefile.am: Added mono-spinlock.h
208 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
210 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
211 these are needed for sendmsg() and also for struct msghdr (at
212 least on Solaris). Solaris still won't build because struct msghdr
213 doesn't have msg_flags, msg_control, or msg_controllen members.
214 (CMSG_SPACE): Define for systems that don't have it.
217 2002-07-20 Dick Porter <dick@ximian.com>
223 * handles.c: Implemented pipe handles
226 * daemon.c: Fixed bug in handle closing.
229 * daemon.c: Forked processes now close all open file descriptors.
231 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
233 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
236 2002-07-19 Martin Baulig <martin@gnome.org>
238 * threads.c (ExitThread): Call exit() if no threads has been
241 2002-07-17 Dick Porter <dick@ximian.com>
243 * daemon-messages.c: Freebsd fixes from Andreas Kohn
244 <andreas.kohn@gmx.net>
246 2002-07-15 Dick Porter <dick@ximian.com>
248 * io.c: Removed bogus console_flush() method, that was just cut
249 and pasted from file_flush when I separated the two handle types.
251 2002-07-12 Dick Porter <dick@ximian.com>
253 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
254 flags. Fixes bug 27633.
256 2002-07-12 Dick Porter <dick@ximian.com>
260 * daemon.c: Use size of sockaddr_un.sun_path from config.h
262 2002-07-12 Dick Porter <dick@ximian.com>
264 * processes.c (CreateProcess): Send stdin, stdout and stderr
265 handles if the startup info doesnt specify new ones
267 * io.c (GetStdHandle): Return the same handle when the same
268 standard handle is requested
270 * handles.c: Pass file descriptors when forking
272 * daemon.c: Use supplied file descriptors when forking a new
276 * daemon-messages.c: Pass stdin, stdout and stderr file
277 descriptors to the daemon (used when forking)
279 2002-07-11 Miguel de Icaza <miguel@ximian.com>
281 * daemon.c (_wapi_daemon_main): Use sizeof
282 (main_socket_address.sun_path) instead of hardcoded 108 value.
284 * handles.c (shared_init): Use sizeof
285 (shared_socket_address.sun_path) instead of hardcoded 108 value.
287 2002-07-10 Dennis Haney <davh@davh.dk>
291 * daemon.c: Lots of documentation, some added error checking, and
292 code readability improvements.
294 * daemon-messages.h: Add the Error request type to improve error
297 * daemon-messages.c: Do a bit more error checking on send() and
298 recv(), and log errors with a higher severity level.
300 2002-07-04 Dick Porter <dick@ximian.com>
302 * daemon.c (process_process_fork): Fix argument handling, due to
303 buggy understanding of g_strsplit() behaviour.
305 2002-07-03 Dick Porter <dick@ximian.com>
308 * threads.c: Implement OpenThread(). Define access-control values
314 * Makefile.am: Added access.h, to hold shared access-control
317 2002-07-02 Dick Porter <dick@ximian.com>
319 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
321 2002-07-02 Dick Porter <dick@ximian.com>
323 * handles.c (shared_init): Make a second attempt to contact the
324 daemon if the shared memory attach succeeds, but the connect()
325 fails. (This copes with the daemon crashing without cleaning up
331 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
332 the daemon, it's now built into the library.
334 2002-06-25 Dick Porter <dick@ximian.com>
339 * daemon.c: Process forking and handle data management
343 * processes.c: Process forking and other support functions
345 2002-06-25 Dick Porter <dick@ximian.com>
347 * versioninfo.h: PE resource decoding
349 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
350 to be told the string length
352 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
353 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
356 2002-06-12 Dick Porter <dick@ximian.com>
359 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
360 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
361 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
363 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
365 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
366 when writing to a closed socket.
368 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
370 * mono-mutex.c (mono_once): New convenience function for my
375 * critical-sections.c:
383 * atomic.c: Use mono_once() rather than pthread_once().
385 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
387 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
388 if multiple threads all try to call _wapi_handle_new() before the
389 shared data has been initialized, it is possible that we could get
390 into a condition where shared_init() is being executed and later
391 threads will pass by pthread_once() due to the fact that it has
392 already been called and so therefor will attempt to use the shared
393 data before it has been completely initialized. If we instead use
394 a standard mutex locking mechanism around shared_init(), we can
395 avoid the situation entirely. By wrapping the mutex locking in a
396 check to see if we've already initialized the data, we can even
397 avoid wasting resources by having to lock/unlock the mutex in any
398 later calls (the only time we'd have to worry about
399 locking/unlocking is the initial race to call shared_init() at
402 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
404 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
406 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
408 * daemon.c, handles.c: rename "sun" local var since it's apparently
409 a #define on Solaris.
411 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
413 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
416 2002-05-15 Dick Porter <dick@ximian.com>
418 * wait.c: Fix a deadlock in WaitForMultipleObjects
420 2002-05-14 Dick Porter <dick@ximian.com>
422 * io.c: Fix a cut&paste error, found by
423 Jaroslaw Kowalski <jarek@atm.com.pl>
425 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
429 2002-05-09 Dick Porter <dick@ximian.com>
437 * Makefile.am: Remove now-unused file wait-private.h
439 2002-05-08 Dick Porter <dick@ximian.com>
441 * shared.c: Better error messages, and report when daemon
442 connection fails rather than blocking forever. Do some more
443 shared memory sanity checking.
445 * handles.c: Better error messages when connecting to shared
446 memory and the handle daemon. Fall back to non-shared handles if
447 an error occurs. Set the default back to 'shared handles'. Fix a
448 crashing bug in scratch space allocation that mangled the block
451 2002-05-07 Miguel de Icaza <miguel@ximian.com>
453 * handles.c (shared_init): Disable SHM for now, people have too
454 many problems with this, and the diagnostics are not helping.
456 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
458 * io.c: CreateFile sets win32 last error.
460 2002-05-05 Dick Porter <dick@ximian.com>
471 * semaphore-private.h:
475 * event-private.h: Simplify the WapiHandleOps struct: take out all
476 the file-specific entries, leaving just the items that operate on
477 handles themselves. Split the close operation into shared and
478 private parts: shared close is called by the daemon.
480 * handles.c: As above, but also pass handle allocation, ref and
481 unref operations to the daemon. Populate the handle_ops array at
482 compile time, because the daemon needs to call ops on handles too.
483 Don't bother to track open handle counts any more, the daemon does
487 * thread-private.h: As above, but also make the thread data
490 * shared.c: Fork a handle daemon if the calling process created
491 the shared memory segment.
496 * Makefile.am: Build a daemon to manage handle allocation and
497 destruction without needing to lock the shared memory
499 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
501 * atomic.c: Changed to use a normal mutex rather than a spinlock
502 since a lot of platforms seem to not have them :\
504 2002-04-30 Dick Porter <dick@ximian.com>
506 * Completely rewrote the handle waiting code: removed the helper
507 thread and its attendant complexity. All handle waiting is now
508 abstracted into the WaitForSingleObject() and
509 WaitForMultipleObjects() functions.
511 * Implemented inter-process sharing of handles using sysv shared
512 memory. This makes handles even more opaque, with a handle now
513 just an index into an array.
515 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
517 * io.c: unitialized pointer in GetCurrentDirectory.
519 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
521 * threads.c: destroy the mutex at thread destruction
522 (if/when thread destruction code will be actually called).
523 When protecting a tls data pointer from the gc, use also the
524 thread id in the key.
526 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
528 * timed-thread.c: avoid race condition when setting the thread to
531 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
533 * jit.h: to more #include lines to avoid breaking compilation
534 under windows when upgrading mingw and w32api to version
537 2002-04-16 Dick Porter <dick@ximian.com>
539 * atomic.h: Explanatory comment about lack of 80386 support
541 2002-04-15 Dick Porter <dick@ximian.com>
543 * atomic.h: use xaddl for InterlockedIncrement() and
544 InterlockedDecrement(). Use cmpxchgl in a loop for
545 InterlockedExchange() and InterlockedExchangePointer().
547 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
549 * unicode.c: fix unicode_len() to not access uninitialized memory
550 (and updated to conform to mono code style).
552 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
554 * io.c: EEXISTS is ignored for directory creation.
555 * mono-mutex.h: remove silly "pragma }" that emacs users insert
556 because they use a broken editor:-)
558 2002-03-28 Dick Porter <dick@ximian.com>
564 * handles.c: Warning cleanups
566 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
568 * unicode.h, unicode.c: changed to gunichar2
569 * io.h, io.c: changed strings to gunichar2*, added
570 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
571 some fixes to FindFirstFile() and friends.
573 2002-03-26 Dick Porter <dick@ximian.com>
575 * types.h: Implement the large integer struct
578 * timefuncs.c: Dummy functions that don't yet implement
579 QueryPerformanceCounter() and QueryPerformanceFrequency()
582 * threads.c: Implement SleepEx()
585 * system.c: Beginnings of GetSystemInfo()
587 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
591 * context.c: Dummy function that doesnt yet implement
595 * atomic.c: Interlocked functions
597 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
599 * threads.c: use a gc-safe hash table to store tls pointers.
601 2002-03-22 Dick Porter <dick@ximian.com>
603 * threads.c: Fix a race condition where a thread can start and
604 exit before the handle has been properly initialised (no reason
605 why the handle couldn't be initialised beforehand, so do so)
607 Fix a ms to ns conversion magnitude thinko.
609 2002-03-21 Dick Porter <dick@ximian.com>
611 * semaphores.c: Fix a problem when waiting for one or more
612 semaphores, and another semaphore is Released (all waiting
613 semaphores assumed they were signalled)
615 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
617 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
618 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
620 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
622 * threads.c (Sleep): bug fix: 1ms == 1000000ns
624 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
626 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
627 threads.c, io.c: added flush method to handles.
629 * io.c: FlushFileBuffers() and FindFirstFile() functions.
631 Thu Mar 7 17:21:52 CET 2002 Paolo Molaro <lupus@ximian.com>
633 * threads.c, timed-thread.c, wait.c: Boehm-GC anable.
635 2002-02-20 Dick Porter <dick@ximian.com>
637 * io-layer.h: Always build without cygwin support on windows
639 Mon Feb 18 15:50:59 CET 2002 Paolo Molaro <lupus@ximian.com>
641 * sockets.c: #undef DEBUG.
643 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
645 * io-layer.h: conditionally include sys/filio.h and sys/sockio.h
646 for FIONBIO, FIONREAD, and SIOCATMARK.
648 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
650 * sockets.c: conditionally include sys/filio.h and sys/sockio.h
651 for FIONBIO, FIONREAD, and SIOCATMARK.
653 2002-02-13 Dick Porter <dick@ximian.com>
655 * sockets.c: Implement shutdown and select
657 2002-02-13 Jeffrey Stedfast <fejj@ximian.com>
659 * mono-mutex.[c,h]: New source files that thinly wrap all pthread
660 functions that take pthread_mutex_t and/or pthread_mutexattr_t
661 arguments for the sake of portability. Implements recursive
662 mutexes and pthread_mutex_timedlock.
664 * critical-sections.c:
671 * wait.c: Use the mono-mutex wrapper portability functions/macros.
673 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
675 2002-01-23 Dick Porter <dick@ximian.com>
677 * sockets.c: Networking support, mostly wrapping BSD socket APIs
678 with handle code, and translating errno into w32 error codes.
680 * macros.h: Some w32 macros used with the socket support
682 * error.c: Implemented GetLastError() and SetLastError()
684 * Makefile.am: Added sockets, with kludge to override some symbols
686 2001-12-17 Dietmar Maurer <dietmar@ximian.com>
688 * unicode.c (_wapi_unicode_to_utf8): byteswap UTF16 strings before
689 passing them to iconv
690 (_wapi_unicode_to_utf8): only swap bytes on LE systems, remove bug
691 from previous commit.
693 2001-12-11 Dick Porter <dick@ximian.com>
695 * io.c: Implement DeleteFile(), GetFileTime(), SetFileTime() and
696 FileTimeToSystemTime().
698 * unicode.c (unicode_len): Nasty way of finding length of unicode
699 string with embedded NULLs (counts until two NULLs together).
701 * mutexes.c (mutex_close):
702 * events.c (event_close): Release the internal pthreads resources
704 2001-11-26 Dick Porter <dick@ximian.com>
