3 * error.[ch]: added errno_to_WSA (). It displays a warning and return
4 WSASYSCALLFAILURE if there is no error mapping for the given errno,
6 * sockets.c: use errno_to_WSA and fixed display of warning for h_errno.
8 2002-10-31 Dick Porter <dick@ximian.com>
11 * io.c: Define and use INVALID_FILE_ATTRIBUTES
13 2002-10-07 Dick Porter <dick@ximian.com>
16 * daemon.c: Use a more accurate time source for process start and
19 2002-10-03 Dick Porter <dick@ximian.com>
23 * threads.c: Fixes for freebsd. Make sure that mutex and condition
24 creation and deletion happen in the process that owns them, when
25 POSIX shared thread objects aren't supported. This breaks on
26 freebsd, as pthread_t is a pointer to data.
28 2002-10-02 Dick Porter <dick@ximian.com>
30 * shared.c: Use mmap() instead of sysv shm for the shared data.
32 * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the
36 * daemon.c: mmap()ed regions survive fork, so just pass the
37 pointer to _wapi_daemon_main instead of mapping it again.
39 2002-10-01 Dick Porter <dick@ximian.com>
41 * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation.
42 Unfortunately libgc uses the same thread suspend technique that I
43 want to, and the two don't mix: libgc will deadlock when it tries
44 to stop the world if a thread has already been suspended by
45 someone else. Just do the simple suspended create rather than the
46 general purpose thread suspension for now.
48 * threads.c: Pass create flags to the timed_thread create call, to
49 implement suspended thread creation. ResumeThread() partially
50 implemented, to cope with the case where a newly created but
51 suspended thread is launched.
53 2002-09-30 Dick Porter <dick@ximian.com>
55 * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
58 2002-09-27 Dick Porter <dick@ximian.com>
60 * semaphores.c: Only include semaphore.h if it's present. Patch
61 for BSD from jmmv@hispabsd.org (Julio Merino).
63 2002-09-27 Dick Porter <dick@ximian.com>
65 * processes.c: Pass environment and working directory to the
66 daemon when forking. Don't let argv[0] be duplicated when looking
67 for the program name. Implement EnumProcessModules (simple
68 version for now, lsof-style later if needed), GetModuleBaseName,
69 {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints
70 aren't available on Linux).
72 * process-private.h: Store the process name, and the working set
76 * handles-private.h: New functions to store and retrieve an array
77 of strings in the scratch space
79 * daemon.c: Don't miss deleting some handles when a client exits
80 (we used to rely on the client doing the final cleanup, but
81 obviously if the client is no longer there the daemon has to do
84 Process forking now sets the environment and the working
87 * io.c: Don't confuse fd 0 with an unassigned handle struct
89 * atomic.h: Add a google cache alternative to the msdn URL
91 2002-09-25 Gonzalo Paniagua Javier <gonzalo@ximian.com>
94 (_wapi_recvfrom): added ECONNRESET to the switch.
96 2002-09-24 Mark Crichton <crichton@gimp.org>
98 * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__.
101 2002-09-19 Mark Crichton <crichton@gimp.org>
103 * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
104 dont have Linux's abstract filesystem for sockets.
106 2002-09-19 Mark Crichton <crichton@gimp.org>
108 * atomic.h: Added SPARC atomic asm code.
109 * daemon.c, handles-private.h, handles.c, wapi-private.h:
110 undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on
111 Solaris 9, however, the code paths don't seem to work. More testing
112 on the shared case is *really* needed.
114 2002-09-03 Dick Porter <dick@ximian.com>
117 * threads.c: Removed PosixKillThread(), because it's not in the
120 2002-08-20 Dick Porter <dick@ximian.com>
122 * handles.c (_wapi_handle_scratch_store): Made stored byte lengths
123 multiples of 4 bytes, to keep header structures aligned. Needed
124 for sparc, at least. (Patch from crichton@gimp.org)
126 * handles.c: Removed 'disable_shm' variable (we've defaulted to
127 building with shm enabled for months now)
129 2002-08-19 Dick Porter <dick@ximian.com>
131 * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
132 for legacy NeXT-based systems.
134 2002-08-12 Dick Porter <dick@ximian.com>
136 * atomic.h: Rename some parameters to avoid c++ keywords (Patch
137 from Joseph Wenninger <kde@jowenn.at>)
139 2002-08-05 Dietmar Maurer <dietmar@ximian.com>
141 * threads.c: use fast spinlocks by default
143 2002-08-02 Dick Porter <dick@ximian.com>
145 * io.c (GetStdHandle): Add a handle reference when returning a
146 duplicate console handle. This fixes the unref_handle errors in
149 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
151 * threads.c (TLS_PTHREAD_MUTEX): define this because else some
154 2002-08-01 Dick Porter <dick@ximian.com>
156 * threads.c: Use atomic spinlocks in TLS functions
159 * Makefile.am: Added mono-spinlock.h
161 2002-07-21 Jeffrey Stedfast <fejj@ximian.com>
163 * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
164 these are needed for sendmsg() and also for struct msghdr (at
165 least on Solaris). Solaris still won't build because struct msghdr
166 doesn't have msg_flags, msg_control, or msg_controllen members.
167 (CMSG_SPACE): Define for systems that don't have it.
170 2002-07-20 Dick Porter <dick@ximian.com>
176 * handles.c: Implemented pipe handles
179 * daemon.c: Fixed bug in handle closing.
182 * daemon.c: Forked processes now close all open file descriptors.
184 Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
186 * sockets.h, io-layer.h, critical-sections.h: don't include config.h
189 2002-07-19 Martin Baulig <martin@gnome.org>
191 * threads.c (ExitThread): Call exit() if no threads has been
194 2002-07-17 Dick Porter <dick@ximian.com>
196 * daemon-messages.c: Freebsd fixes from Andreas Kohn
197 <andreas.kohn@gmx.net>
199 2002-07-15 Dick Porter <dick@ximian.com>
201 * io.c: Removed bogus console_flush() method, that was just cut
202 and pasted from file_flush when I separated the two handle types.
204 2002-07-12 Dick Porter <dick@ximian.com>
206 * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
207 flags. Fixes bug 27633.
209 2002-07-12 Dick Porter <dick@ximian.com>
213 * daemon.c: Use size of sockaddr_un.sun_path from config.h
215 2002-07-12 Dick Porter <dick@ximian.com>
217 * processes.c (CreateProcess): Send stdin, stdout and stderr
218 handles if the startup info doesnt specify new ones
220 * io.c (GetStdHandle): Return the same handle when the same
221 standard handle is requested
223 * handles.c: Pass file descriptors when forking
225 * daemon.c: Use supplied file descriptors when forking a new
229 * daemon-messages.c: Pass stdin, stdout and stderr file
230 descriptors to the daemon (used when forking)
232 2002-07-11 Miguel de Icaza <miguel@ximian.com>
234 * daemon.c (_wapi_daemon_main): Use sizeof
235 (main_socket_address.sun_path) instead of hardcoded 108 value.
237 * handles.c (shared_init): Use sizeof
238 (shared_socket_address.sun_path) instead of hardcoded 108 value.
240 2002-07-10 Dennis Haney <davh@davh.dk>
244 * daemon.c: Lots of documentation, some added error checking, and
245 code readability improvements.
247 * daemon-messages.h: Add the Error request type to improve error
250 * daemon-messages.c: Do a bit more error checking on send() and
251 recv(), and log errors with a higher severity level.
253 2002-07-04 Dick Porter <dick@ximian.com>
255 * daemon.c (process_process_fork): Fix argument handling, due to
256 buggy understanding of g_strsplit() behaviour.
258 2002-07-03 Dick Porter <dick@ximian.com>
261 * threads.c: Implement OpenThread(). Define access-control values
267 * Makefile.am: Added access.h, to hold shared access-control
270 2002-07-02 Dick Porter <dick@ximian.com>
272 * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
274 2002-07-02 Dick Porter <dick@ximian.com>
276 * handles.c (shared_init): Make a second attempt to contact the
277 daemon if the shared memory attach succeeds, but the connect()
278 fails. (This copes with the daemon crashing without cleaning up
284 * shared.c (_wapi_shm_attach): Don't exec() anything when we fork
285 the daemon, it's now built into the library.
287 2002-06-25 Dick Porter <dick@ximian.com>
292 * daemon.c: Process forking and handle data management
296 * processes.c: Process forking and other support functions
298 2002-06-25 Dick Porter <dick@ximian.com>
300 * versioninfo.h: PE resource decoding
302 * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need
303 to be told the string length
305 * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks.
306 Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to
309 2002-06-12 Dick Porter <dick@ximian.com>
312 * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the
313 daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw
314 Kowalski <jarek@atm.com.pl> for pointing out the bogosity.
316 2002-06-10 Jaroslaw Kowalski <jarek@atm.com.pl>
318 * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
319 when writing to a closed socket.
321 2002-06-08 Jeffrey Stedfast <fejj@ximian.com>
323 * mono-mutex.c (mono_once): New convenience function for my
328 * critical-sections.c:
336 * atomic.c: Use mono_once() rather than pthread_once().
338 2002-06-06 Jeffrey Stedfast <fejj@ximian.com>
340 * handles.c (_wapi_handle_new): pthread_once() is not atomic, so
341 if multiple threads all try to call _wapi_handle_new() before the
342 shared data has been initialized, it is possible that we could get
343 into a condition where shared_init() is being executed and later
344 threads will pass by pthread_once() due to the fact that it has
345 already been called and so therefor will attempt to use the shared
346 data before it has been completely initialized. If we instead use
347 a standard mutex locking mechanism around shared_init(), we can
348 avoid the situation entirely. By wrapping the mutex locking in a
349 check to see if we've already initialized the data, we can even
350 avoid wasting resources by having to lock/unlock the mutex in any
351 later calls (the only time we'd have to worry about
352 locking/unlocking is the initial race to call shared_init() at
355 Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
357 * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
359 Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
361 * daemon.c, handles.c: rename "sun" local var since it's apparently
362 a #define on Solaris.
364 Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
366 * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
369 2002-05-15 Dick Porter <dick@ximian.com>
371 * wait.c: Fix a deadlock in WaitForMultipleObjects
373 2002-05-14 Dick Porter <dick@ximian.com>
375 * io.c: Fix a cut&paste error, found by
376 Jaroslaw Kowalski <jarek@atm.com.pl>
378 2002-05-10 Dan Lewis <dihlewis@yahoo.co.uk>
382 2002-05-09 Dick Porter <dick@ximian.com>
390 * Makefile.am: Remove now-unused file wait-private.h
392 2002-05-08 Dick Porter <dick@ximian.com>
394 * shared.c: Better error messages, and report when daemon
395 connection fails rather than blocking forever. Do some more
396 shared memory sanity checking.
398 * handles.c: Better error messages when connecting to shared
399 memory and the handle daemon. Fall back to non-shared handles if
400 an error occurs. Set the default back to 'shared handles'. Fix a
401 crashing bug in scratch space allocation that mangled the block
404 2002-05-07 Miguel de Icaza <miguel@ximian.com>
406 * handles.c (shared_init): Disable SHM for now, people have too
407 many problems with this, and the diagnostics are not helping.
409 2002-05-06 Dan Lewis <dihlewis@yahoo.co.uk>
411 * io.c: CreateFile sets win32 last error.
413 2002-05-05 Dick Porter <dick@ximian.com>
424 * semaphore-private.h:
428 * event-private.h: Simplify the WapiHandleOps struct: take out all
429 the file-specific entries, leaving just the items that operate on
430 handles themselves. Split the close operation into shared and
431 private parts: shared close is called by the daemon.
433 * handles.c: As above, but also pass handle allocation, ref and
434 unref operations to the daemon. Populate the handle_ops array at
435 compile time, because the daemon needs to call ops on handles too.
436 Don't bother to track open handle counts any more, the daemon does
440 * thread-private.h: As above, but also make the thread data
443 * shared.c: Fork a handle daemon if the calling process created
444 the shared memory segment.
449 * Makefile.am: Build a daemon to manage handle allocation and
450 destruction without needing to lock the shared memory
452 2002-04-30 Jeffrey Stedfast <fejj@ximian.com>
454 * atomic.c: Changed to use a normal mutex rather than a spinlock
455 since a lot of platforms seem to not have them :\
457 2002-04-30 Dick Porter <dick@ximian.com>
459 * Completely rewrote the handle waiting code: removed the helper
460 thread and its attendant complexity. All handle waiting is now
461 abstracted into the WaitForSingleObject() and
462 WaitForMultipleObjects() functions.
464 * Implemented inter-process sharing of handles using sysv shared
465 memory. This makes handles even more opaque, with a handle now
466 just an index into an array.
468 2002-04-25 Dan Lewis <dihlewis@yahoo.co.uk>
470 * io.c: unitialized pointer in GetCurrentDirectory.
472 Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>
474 * threads.c: destroy the mutex at thread destruction
475 (if/when thread destruction code will be actually called).
476 When protecting a tls data pointer from the gc, use also the
477 thread id in the key.
479 Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro <lupus@ximian.com>
481 * timed-thread.c: avoid race condition when setting the thread to
484 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
486 * jit.h: to more #include lines to avoid breaking compilation
487 under windows when upgrading mingw and w32api to version
490 2002-04-16 Dick Porter <dick@ximian.com>
492 * atomic.h: Explanatory comment about lack of 80386 support
494 2002-04-15 Dick Porter <dick@ximian.com>
496 * atomic.h: use xaddl for InterlockedIncrement() and
497 InterlockedDecrement(). Use cmpxchgl in a loop for
498 InterlockedExchange() and InterlockedExchangePointer().
500 Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
502 * unicode.c: fix unicode_len() to not access uninitialized memory
503 (and updated to conform to mono code style).
505 Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>
507 * io.c: EEXISTS is ignored for directory creation.
508 * mono-mutex.h: remove silly "pragma }" that emacs users insert
509 because they use a broken editor:-)
511 2002-03-28 Dick Porter <dick@ximian.com>
517 * handles.c: Warning cleanups
519 2002-03-27 Dan Lewis <dihlewis@yahoo.co.uk>
521 * unicode.h, unicode.c: changed to gunichar2
522 * io.h, io.c: changed strings to gunichar2*, added
523 SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(),
524 some fixes to FindFirstFile() and friends.
526 2002-03-26 Dick Porter <dick@ximian.com>
528 * types.h: Implement the large integer struct
531 * timefuncs.c: Dummy functions that don't yet implement
532 QueryPerformanceCounter() and QueryPerformanceFrequency()
535 * threads.c: Implement SleepEx()
538 * system.c: Beginnings of GetSystemInfo()
540 * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion
544 * context.c: Dummy function that doesnt yet implement
548 * atomic.c: Interlocked functions
550 Mon Mar 25 13:01:40 CET 2002 Paolo Molaro <lupus@ximian.com>
552 * threads.c: use a gc-safe hash table to store tls pointers.
554 2002-03-22 Dick Porter <dick@ximian.com>
556 * threads.c: Fix a race condition where a thread can start and
557 exit before the handle has been properly initialised (no reason
558 why the handle couldn't be initialised beforehand, so do so)
560 Fix a ms to ns conversion magnitude thinko.
562 2002-03-21 Dick Porter <dick@ximian.com>
564 * semaphores.c: Fix a problem when waiting for one or more
565 semaphores, and another semaphore is Released (all waiting
566 semaphores assumed they were signalled)
568 2002-03-29 Dan Lewis <dihlewis@yahoo.co.uk>
570 * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory,
571 RemoveDirectory, GetFileAttributes, GetFileAttributesEx
573 2002-03-19 Dietmar Maurer <dietmar@ximian.com>
575 * threads.c (Sleep): bug fix: 1ms == 1000000ns
577 2002-03-19 Dan Lewis <dihlewis@yahoo.co.uk>
579 * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c,
580 threads.c, io.c: added flush method to handles.
582 * io.c: FlushFileBuffers() and FindFirstFile() functions.
584 Thu Mar 7 17:21:52 CET 2002 Paolo Molaro <lupus@ximian.com>
586 * threads.c, timed-thread.c, wait.c: Boehm-GC anable.

598 * io-layer.h: conditionally include sys/filio.h and sys/sockio.h
599 for FIONBIO, FIONREAD, and SIOCATMARK.
601 2002-02-14 Jeffrey Stedfast <fejj@ximian.com>
603 * sockets.c: conditionally include sys/filio.h and sys/sockio.h

614 arguments for the sake of portability. Implements recursive
615 mutexes and pthread_mutex_timedlock.
617 * critical-sections.c:
624 * wait.c: Use the mono-mutex wrapper portability functions/macros.
626 * pthread-compat.[c,h]: Replaced by mono-mutex.[c,h]
628 2002-01-23 Dick Porter <dick@ximian.com>
630 * sockets.c: Networking support, mostly wrapping BSD socket APIs
631 with handle code, and translating errno into w32 error codes.

727 (from Nick Drochak <ndrochak@gol.com>)
729 2001-11-10 Dick Porter <dick@ximian.com>

737 * pthread-compat.c: added some include files to make it compile on
740 2001-11-08 Dick Porter <dick@ximian.com>
744 This is a library emulating the win32 threading and IO API.
