We trust pthread_setspecific return value to tell if we tried to store to an invalid slot. 2010-04-04 Zoltan Varga * processes.c: Applied more openbsd changes from Robert Nagy . 2010-04-03 Zoltan Varga * processes.c: Applied more openbsd changes from Robert Nagy . 2010-04-03 Zoltan Varga * processes.c: Applied some openbsd changes from Robert Nagy . 2010-03-26 Zoltan Varga * sockets.c: Apply some openbsd changes from openbsd ports. 2010-03-26 Zoltan Varga * shared.c: Disable shared supported by default, it can be enabled by setting the MONO_ENABLE_SHM env variable. 2009-03-22 Rodrigo Kumpera * threads.h: Add wapi_self_interrupt. * wthreads.c: Add wapi_self_interrupt which puts the current thread in interrupted state. * wthreads.c (wapi_thread_clear_wait_handle): Previous handle can possibly be NULL if an async interrupt cleared it. This is safe because it is only async cleared if running inside a handler block. 2010-03-06 Gonzalo Paniagua Javier * processes.c: made ShellExecuteEx actually work when the file name to execute is quoted. Display a message intead of blindly ignoring the result of g_shell_parse_argv(). Fixes bug #385497. 2010-03-05 Zoltan Varga * shared.c (shm_semaphores_init): Applied patch from Cal Page (age.cal@gmail.com). Fix support for USE_SHM. 2010-02-25 Geoff Norton * wait.c: If any of our handles are shared, we need to do a polling wait so we're notified of the signal change. Wed Feb 24 16:01:37 CET 2010 Paolo Molaro * Makefile.am: don't install the headers anymore, they are private. 2010-02-20 Zoltan Varga * versioninfo.c (VerLanguageName): Remove code duplication a bit. 2009-12-02 Miguel de Icaza * processes.c (EnumProcesses): Add support for OSX, patch from Tom Philpot 2009-11-30 Carlos Alberto Cortez * io.cs: In CopyFile check if the destination already exists before trying to open it, and if it is the same as the source, report an error, just as .net does. We do the check here to take advantage of the IOMAP capability. Fixes #510230. 2009-11-13 Jonathan Chambers * mono-mutex.h: Implementation for Windows platform. Code contributed under MIT/X11 license. 2009-11-13 Zoltan Varga * processes.c: Include mono-path.h. 2009-11-12 Geoff Norton * processes.c: match_procname_to_modulename should resolve symlinks when checking if two process modules match. 2009-11-04 Jonathan Chambers * mono-mutex.h: Add skeleton implementation for Windows platform. Code contributed under MIT/X11 license. 2009-10-21 Gonzalo Paniagua Javier * sockets.[ch]: fix function definition. 2009-10-21 Gonzalo Paniagua Javier * sockets.[ch]: added TransmitFile implementation. 2009-10-04 Zoltan Varga * processes.c: Implement get_process_name_from_proc () on solaris. 2009-09-24 Zoltan Varga * processes.c (load_modules): Applied patch from Thomas Philpot (tom.philpot@logos.com). Fixes #533893. 2009-09-15 Jeffrey Stedfast * io.c (CreateFile): In the directory fallback case, use _wapi_open() again so that IOMAP magic happens. (CopyFile): Need to consistently use _wapi_open() here too. (ReplaceFile): Use _wapi_open() here too and get rid of the fallback code that tried re-opening the file w/o O_TRUNC since there's no reason to do that. 2009-09-05 Zoltan Varga * handles.c (_wapi_handle_real_new): Call _wapi_process_reap () when running out of shared handes. Fixes #536776. * processes.c (CreateProcess): Return false and set the error to ERROR_OUTOFMEMORY when a process handle cannot be created. (ShellExecuteEx): Propagate an ERROR_OUTOFMEMORY error code. Fixes part of #536776. 2009-09-01 Zoltan Varga * processes.c (EnumProcessModules): Applied patch from Romain Tartière (romain@blogreen.org). Fix this on freebsd/OSX. Fixes #533893. 2009-08-18 Christian Hergert * wthreads.c: Roll back change for thread-id as it "embraces and extends" the api by passing word-size for thread id on s390 and amd64. 2009-08-18 Christian Hergert * security.c: * processes.c: * wthreads.c: Be explicit when we are changing word sizes. 2009-08-18 Christian Hergert * processes.c: Fix method declaration warnings. * sockets.c: getsockopt() wants socklen_t for size. 2009-08-04 Miguel de Icaza * posix.c (_wapi_stdhandle_create): Split this into a new file to more easily support non-Posix platforms. 2009-07-20 Geoff Norton * thread-private.h: Use the new mono-semaphore.h. 2009-06-25 Gonzalo Paniagua Javier * sockets.c: add the error number to the message so we can figure out when this happens. 2009-06-25 Gonzalo Paniagua Javier * wait.c: add missing 'break'. 2009-06-20 Zoltan Varga * atomic.h: Fix ilp32 support on ppc. 2009-05-28 Mark Probst * collection.c (_wapi_collection_init): If pthread_create() fails, try again with larger and then with no stack size set. Fixes #470336. 2009-05-26 Zoltan Varga * shared.c (_wapi_shm_file): Avoid creating a .wapi directory here, create it in _wapi_shm_file_open (), since platforms using posix shm don't need it. 2009-05-22 Miguel de Icaza * wapi_glob.c: Do not need sys/param.h anymore, we now use the POSIX PATH_MAX instead of BSD's MAXPATHLEN * handles.c: Do not pull a reference to sockets if they are disabled. * sockets.c: Allow for ports to define their own ioctlsocket. * wthreads.c: Remove obsolete code that I recently introudced (the hook for mono_register_thread_attr. 2009-05-22 Miguel de Icaza * versioninfo.c: One missing signature, fixed. 2009-05-21 Miguel de Icaza * daemon.c: Remove more DEBUG ifdef mess. * shared.c (_wapi_shm_attach): Implemention for DISABLE_SHARED_HANDLES 2009-05-20 Miguel de Icaza * sockets.c (ioctlsocket): Move support for MacOS semantics to the ioctlsocket from the ifdef that was previously on metadata/ * wapi_glob.c (_wapi_glob): Use PATH_MAX from limits.h instead of the BSD name from sys/param.h (MAXPATHLEN) Do not include pwd.h as it is not used. * thread-private.h: Use indent ifdef style for clarity * sockets-wrappers.h: sys/socket.h conditional * daemon-messages.h: sys/uio.h conditional. * sockets.c: sys/ioctl.h conditional * wthreads.c: work around for platforms with no thread fetching information. * versioninfo.c: Use the portable mono_map_ interface instead of using mmap directly and change the style to the Mono style. Remove more DEBUG/ifdefs combos * shared.c: Split the code to make DISABLE_SHARED remove all the code that does not use the shared handles. Before it merely removed some of it, with this we avoid hacks on platforms that can not implement it. Split the code to reduce the amount of ifdefs. Remove #ifdef DEBUG from the source and use a macro instead. 2009-05-20 Miguel de Icaza * locking.c: Split locking code into a separate file. 2009-05-18 Miguel de Icaza * daemon.c: Move the compile check of MONO_SIZEOF_SUNPATH to the file that uses it. * Rename `threads.c' to `wthreads.c' as broken build systems are not able to cope with two files with the same name across multiple directories. 2009-05-15 Geoff Norton * handles.c: Don't start the collection thread if we've disabled shared handles. 2009-05-12 Zoltan Varga * collection.c (collection_thread): Get rid of all the ifdefs and gcc attributes, simply return NULL. 2009-05-11 Zoltan Varga * shared.c: Applied patch from Koushik K. Dutta (koush@koushikdutta.com). Fix the build on android. 2009-05-09 Miguel de Icaza * messages.c: Split the scan into common and uncommon messages to allow the messages that are not produced by Mono to be removed on embedded scenarios. * messages.c (message_string): instead of having a gigantic switch table, use a sorted structure in memory and do a binary search on it. This reduces the runtime size by 49k and the debugging symbols by 400k. 2009-04-29 Gonzalo Paniagua Javier * sockets.c: don't display a warning when connect() fails because the socket was closed in another thread. 2009-04-23 Rodrigo Kumpera * shared.c: Fix a bunch of memleaks. 2009-03-27 Zoltan Varga * threads.h: Add a comment to CreateThread. 2009-03-20 Zoltan Varga * threads.c handles.c wait.c: Change location of gc_wrapper.h. 2009-02-22 Robert Jordan * sockets.c: implement WSASend/WSARecv using sendmsg/recvmsg. Fixes #470021. Code is contributed under MIT/X11 license. 2009-02-20 Gonzalo Paniagua Javier * events.c: fix event_signal and namedevent_signal to actually signal the handle. 2009-02-12 Gonzalo Paniagua Javier * io.c: EXDEV when moving directories fails now without creating a file in the destination. Fixes bug #326983. 2009-02-09 Zoltan Varga * wait.c (WaitForMultipleObjectsEx): Initialize poll variable. 2009-02-05 Miguel De Icaza * sockets.c (_wapi_setsockopt): SO_REUSEPORT is needed also on MacOS X. Fixes bug #471292 2009-01-29 Zoltan Varga * shared.c: Fall back to file based shared storage if shm_open () fails because /dev/shm is not mounted. * shared.c: Add an alternative implementation using shared memory instead of files. This fixes problems where the mono process would spin up the disk every x secs on laptops. Fixes #434566, #415373 and #321949. 2009-01-16 Miguel de Icaza * sockets.c (WSASend): Fix memory leak, and optimize for the case with 1 segment. This should really use writev or sendmsg to use the kernel scatter/gather facility instead of emulating it by copying buffers. 2009-01-26 Rodrigo Kumpera * critical-sections.h (Enter/LeaveCriticalSection): Show helpfull warning messages before crashing. 2009-01-26 Rodrigo Kumpera * handles-private.h (_wapi_handle_set_signal_state): Show helpfull warning messages before crashing. 2009-01-26 Jeffrey Stedfast * mono-mutex.[c,h]: Removed GPLv2 copyright notice which should not have been there. 2009-01-20 Rodrigo Kumpera * threads.c: Add wapi_current_thread_desc that produces a string representation of the current thread state. * threads.h: Export wapi_current_thread_desc. 2009-01-18 Zoltan Varga * io.c (GetDiskFreeSpaceEx): Applied patch from Koushik Dutta (koush@koushikdutta.com). Disable this on android. 2009-01-16 Rodrigo Kumpera * handles.c (_wapi_handle_timedwait_signal_handle): Don't use the set_wait_handle/clear_wait_handle machinery for alertable waits in case of non-alertable waits. Non-alertable waits must continue and wait on the cond as this will release the lock. Otherwise this will cause a deadlock as anyone trying to pulse the cond will block trying to acquire the said lock because the thread in non-alertable wait will be busy looping in WaitForSingleObjectEx or similar function, never releasing the lock. Thou this fixes quite a few of the hangs introduced by non-pooling alertable waits, the long term plan is to verify if all non-alertable waits really need to be as such. 2009-01-14 Zoltan Varga * handles-private.h (_wapi_handle_set_signal_state): Set the signalled state of the handle while locking the global signal cond mutex. * wait.c (WaitForMultipleObjectsEx): Check the signalled state of handles inside the critical section before waiting, otherwise we could go to waiting even when the handles are already signalled. 2009-01-13 Zoltan Varga Reapply r122913, this time handling processes by falling back to polling. * handles.c: Rework the way the global signal stuff is handled: instead of allocating a separate mutex/condvar pair for it, allocate a normal handle. This way, it can reuse the alertable waiting code, allowing WaitForMultipleObject to work without polling. 2009-01-09 Miguel de Icaza Incorporate a few patches from Paolo, slightly modified: * handles.c (_wapi_handle_check_share): On non-Linux systems, do not even compile in the code that scans for /proc/fd, and go directly to the fallback function. 2009-01-09 Paolo Molaro (lupus@ximian.com) * handles.c: Do not include some header files in platforms that lack it. 2009-01-09 Miguel de Icaza * messages.c: Eliminate a warning. 2009-01-09 Paolo Molaro (lupus@ximian.com) * error.c: On some platforms that do not define these variables, do not use them. * security.c, io-private.h: Only include some headers if they exist on the system * sockets.c, sockets.h: do not import on this header files that are only consumed internally in sockets.c. 2009-01-09 Zoltan Varga * threads.c (_wapi_thread_apc_pending): Check for thread->wait_handle == INTERRUPTION_REQUESTED_HANDLE too. (wapi_interrupt_thread): Rework the comments, the thread is no longer required to call QueueUserAPC to make the wait functions return. * threads.c handles.c threads-internal.h: Implement alertable waits without polling. 2009-01-08 Geoff Norton * processes.c: Fix the osx version check to properly detect 10.5 v 10.4 2009-01-08 Christian Prochnow * types.h: added WapiULargeInteger. * uglify.h: added ULARGE_INTEGER, PULARGE_INTEGER. * io.h: added WapiDriveType, added method declarations for GetDiskFreeSpaceEx and GetDriveType * io.c: added GetDiskFreeSpaceEx() to query disk size and free space via statvfs or statfs system call. added GetDriveType to query drive type via /etc/mtab or /etc/mnttab. 2009-01-07 Geoff Norton * processes.c: Properly implement support for Process.Modules on OSX. Fixes OSX on nunit 2.4 2009-01-07 Rodrigo Kumpera * io.c (GetCurrentDirectory): Avoid calling g_get_current_dir straight away as it doesn't handle ENAMETOOLONG correctly. As a bonus we avoid allocating memory in the common path. 2009-01-07 Geoff Norton * processes.c: Only use open -W on OSX 10.5+. Patch from Miguel 2008-12-19 Bill Holmes * processes.c (get_module_name) : adjust size for unicode characters.

Fixes bug 413723, patch by Casey Marshall 2008-07-28 Dick Porter * handles.c (_wapi_handle_count_signalled_handles): Remove an unmatched _wapi_handle_ref(). Fixes bug 410743. 2008-07-15 Rodrigo Kumpera * versioninfo.c (map_pe_file): Fix memory leak. 2008-07-01 Zoltan Varga * process-private.h (_WAPI_PROCESS_UNHANDLED_PID_MASK): Fix the amd64 build. 2008-06-27 Dick Porter * processes.c: Implement a form of process pseudo-handle to allow non-mono processes to be manipulated. Fixes bug 313231. * wait.c: Check for process pseudo-handles and fail if an attempt is made to wait on one. 2008-06-19 Dick Porter * sockets.c: Implement WSASend() and WSAReceive(). 2008-06-02 Dick Porter * wapi.h: * Makefile.am: * messages.h: * messages.c: Implement FormatMessage, fixes bug 321827. 2008-05-29 Dick Porter * sockets.c (socket_close): Clear any saved errors (_wapi_connect): Don't save EWOULDBLOCK errors here, as that breaks async connects. (Bug 377589 test case broken by the previous fix to bug 356552) 2008-05-25 Zoltan Varga * thread-private.h (struct _WapiHandle_thread): Remove 'owner_pid' field. Reorder fields so this struct (which is the biggest of the handle structs) takes less space. * threads.c (QueueUserAPC): Make this function signal safe by adding some restrictions on its usage. 2008-05-14 Zoltan Varga * mono-mutex.h: Get rid of the #ifdef __cplusplus defines, use G_BEGIN_DECLS /G_END_DECLS. 2008-05-07 Dick Porter * io.c (FindNextFile): Handle symlinks correctly. Fixes bug 385765. 2008-04-25 Zoltan Varga * handles.c (_wapi_handle_check_share): Fix a crash introduced by the lazy creation of wapi handle slots. 2008-04-24 Zoltan Varga * handles.c (shared_init): Align _wapi_fd_reserve to a multiple of _WAPI_HANDLE_INITIAL_COUNT to avoid a problem when allocating handles. 2008-04-23 Zoltan Varga * handles.c: Initialize the handle array entries on demand to save memory. * wapi-private.h (_WAPI_HANDLE_INITIAL_COUNT): Decrease this to 256 to save memory. * handles-private.h (_WAPI_PRIVATE_MAX_SLOTS): Increase this to 1024*16 to compensate for the decrease in _WAPI_HANDLE_INITIAL_COUNT. * threads.c: Use #ifdef instead of #if for checking for valgrind/memcheck.h. 2008-04-22 Dick Porter * wapi_glob.c (globextend): Comment out the code using ARG_MAX, as that is broken on the latest opensuse. 2008-04-21 Dick Porter * io.c (DeleteFile): Disable for now the bug fix for 323389, it's breaking too much other stuff. 2008-04-20 Geoff Norton * processes.c: Fix the _NSGetEnviron define to prevent an impropoer pointer dereference. 2008-04-18 Miguel de Icaza * Applied patch from Dick Porter from bug #380649 2008-04-17 Dick Porter * io.c (DeleteFile): Check file shares before deleting a file. Fixes bug 323389. 2008-04-17 Dick Porter * io.c (DeleteFile): Return ERROR_ACCESS_DENIED if the file is readonly. Fixes bug 378229. 2008-04-11 Geoff Norton * processes.c: The global extern environ doesn't exist on Mac.

Fixes bug 325463. 2008-03-27 Dick Porter * processes.c (match_procname_to_modulename): Check the whole process name first, in case it is recorded as an absolute path. Fixes bug 360348. 2008-03-27 Dick Porter * processes.c (ShellExecuteEx): Grotty kludge to work around unpleasant feature in g_shell_parse_argv() where it treats '#' embedded in a filename as a comment marker, and throws away the rest of the line. When we're directly opening URLs quote the filename, to avoid this. Fixes bug 371567. 2008-03-25 Dick Porter * wapi-private.h (_WAPI_HANDLE_VERSION): Increment file layout version * threads.c: Make thread handles private to the process that owns them. 2008-03-22 Kornél Pál * io-layer.h: Windows: Rename GetProcessId to __GetProcessId for targets not supporting it. This fixes MSVC build with new Windows SDKs that declare GetProcessId unconditionally. 2008-03-20 Kornél Pál * io-layer.h: Removed Windows version macros. Thu Mar 13 16:24:53 CET 2008 Paolo Molaro * processes.c: properly check for executable files (fixes bug #368829). 2008-02-05 Dick Porter * versioninfo.c (VerLanguageName): Implement VerLanguageName. 2008-01-31 Bill Holmes * processes.c (match_procname_to_modulename) : Added to check if the last part of module name is equal to the process name. * processes.c (EnumProcessModules) : Changed the first entry in the returned modules array (the process module) to be populated from the entry found in /proc//maps. * processes.c (get_module_name & GetModuleInformation) : In the case where the module passed in is NULL, search the /proc//maps for a name that matches the process name to populate the return information. Fixes #357062 2008-01-29 Zoltan Varga * security.c (RevertToSelf): Make this return TRUE if impersonating is not supported. * sockets.c (_wapi_connect): Add a workaround to a solaris x86 problem where getsockopt (SO_ERROR) doesn't return an error code after connect () fails. Fixes #356552. 2008-01-23 Dick Porter * versioninfo.c (get_string_block): When stepping over the StringTable block, do not read an extra block at the end.

Fixes bug 354856. 2008-01-16 Dick Porter * threads.c (_wapi_thread_set_termination_details): Move the thread abandonment to outside the shared handle lock. Fixes bug 349680. 2008-01-16 Dick Porter * versioninfo.c (VerQueryValue): Include trailing null in returned string length, for MS compatibility. 2008-01-09 Dick Porter * versioninfo.c (get_ptr_from_rva, scan_resource_dir): Make it work on big-endian systems. (scan_resource_dir): Copy the resource directory entry and byteswap if necessary so it works big-endian. This fixes bug 345972 for real this time. (VerQueryValue): String values set the length to the number of unicode chars, but the data length reported was already correct so don't halve it again. Fixes the previous fix for bug 345972. (GetFileVersionInfo): On big-endian systems, scan the resource data and turn all unicode strings into UTF-16BE. FileVersionInfo now works big-endian. 2008-01-04 Dick Porter * versioninfo.c (VerQueryValue): Returned buffer length counts chars not bytes for string data. Fixes bug 345972 again. (get_enclosing_section_header): Make sure values read are treated as LE. Fixes crash on ppc reported in bug 345972. 2007-12-17 Mark Probst * threads.c: Guard against a race condition involving thread_hash_key that can occur during shutdown. 2007-12-08 Zoltan Varga * processes.c: Include sys/mkdev.h if exists.

Fixes bug 343353. 2007-11-21 Dick Porter * processes.c (load_modules): Rewrite based on the libgc /proc//maps parsing to avoid using glib functions only available since 2004. (load_modules): Check for duplicates before adding a module to the list. 2007-11-15 Dick Porter * processes.c (load_modules): Don't bother if we don't have g_strsplit_set() and g_strv_length(). Allows building against old glib versions. (EnumProcessModules): Don't miss the first module returned by load_modules(). 2007-11-15 Dick Porter * processes.c: Implement process module support by reading from /proc if it's available. * versioninfo.h: * versioninfo.c: New functions to implement PE file version info support. 2007-11-08 Dick Porter * critical-sections.h (EnterCriticalSection): Disable the critical section asserts for the release branch 2007-11-05 Kornél Pál * io-layer.h: Added includes for run-time GetProcessId API detection for Windows. 2007-10-26 Dick Porter * shared.c (_wapi_shm_file_open): Set the umask when opening shared files, so restrictive defaults don't prevent subsequent processes re-opening them. 2007-10-18 Zoltan Varga * atomic.h (InterlockedCompareExchange): Fix the ia64 version so it works for negative values too. Hopefully fixes #332700. 2007-09-26 Dick Porter * io-portability.c (_wapi_io_scandir): Only update the error status of glob() when performing a secondary glob() if the first returned an error. Fixes bug 325107. 2007-09-12 Marek Habersack * io-portability.c: options_init moved to utils/mono-io-portability.c Do not initialize portability helpers here, it's done in mono_runtime_init. find_file and find_in_dir moved to utils/mono-io-portability.c 2007-09-09 Robert Jordan * sockets.c (_wapi_setsockopt): Add support for FreeBSD multicast sockets. Fixes #81891. Code is contributed under MIT/X11 license. 2007-09-03 Atsushi Enomoto * processes.h, processes.c : ok, they are simple string. 2007-09-03 Atsushi Enomoto * processes.h : sigh, I really hate fixing them on windows :( 2007-09-03 Atsushi Enomoto * processes.c : fix build again. 2007-09-03 Atsushi Enomoto * processes.h : removed extra parameters from CreateProcessWithLogonW. 2007-09-03 Atsushi Enomoto * processes.c, processes.h: added CreateProcessWithLogonW(). For now it just calls CreateProcess(). * io-layer.h : CreateProcessWithLogonW() requires WINVER 0x0500 on Windows. 2007-08-23 Robert Jordan * processes.[c|h]: Implement Get|SetPriorityClass (). Code is contributed under MIT/X11 license. Tue Aug 21 20:08:09 CEST 2007 Paolo Molaro * io.c: made convert_arg_to_utf8() and write_file() static. Worked around gcc's incorrect warning. 2007-08-20 William Holmes *io.c: Added implementation for ReplaceFile. *io.h: Added deceleration for ReplaceFile method. Code is contributed under MIT/X11 license. 2007-08-20 Wade Berrier * processes.c: include sys/resource.h for rusage to fix mac 10.3 build Mon Aug 20 12:36:42 CEST 2007 Paolo Molaro * processes.c: implemented query for user/system times using getrusage (). 2007-08-10 Dick Porter * sockets.c (_wapi_getsockopt, _wapi_setsockopt): Check the option level as well as the name when mangling some of the values. Fixes bug 82000. 2007-08-02 Dick Porter * sockets.c: Changes in error handling, and move the SO_REUSEADDR setting from metadata/socket-io.c. 2007-08-01 Dick Porter * io-portability.c (_wapi_io_scandir): Special-case patterns ending in '.*' so that files with no extension are also matched. Fixes bug 82212. * wapi_glob.h: * wapi_glob.c: Reinstate WAPI_GLOB_APPEND, and add WAPI_GLOB_UNIQUE to avoid matching the same entry twice when appending. 2007-07-26 Dick Porter * handles-private.h: * thread-private.h: * handles.h: * critical-sections.c: * handles.c: * critical-section-private.h: * error.h: * threads.c: * error.c: Clean up TLS and pthreads structures. Finishes off bug 78739. * collection.c (collection_thread): Exit the collection thread if the io-layer has been cleaned up. * mono-mutex.h (mono_mutexattr_destroy): Add this define too Mon Jul 23 10:40:35 CEST 2007 Paolo Molaro * timefuncs.c: make TickCount measure from boot time if it's available. 2007-07-19 Juraj Skripsky * io.c (MoveFile): Fix a leak. Fri Jul 13 12:46:15 CEST 2007 Paolo Molaro * handles-private.h, handles.c, thread-private.h, threads.c, uglify.h, wait.c: temporarily revert the alertable wait changes (r79386) until the deadlock issues are fixed. 2007-06-22 Dick Porter * shared.c: The non-shared mutexes weren't being initialised properly on macos. Fixes bug 81929. 2007-06-13 Randolph Chung * atomic.h: Enable for all hppa targets. * Makefile.am: rename hppa_atomic.s to hppa_atomic.S so the preprocessor can handle the file. * hppa_atomic.s: Renamed to ... * hppa_atomic.S: ... and updated to work on both HPUX and Linux. 2007-06-13 Dick Porter * handles.c (timedwait_signal_wait_cond): Alertable waits on private handles are now interrupted by signalling the same condition that would end the wait if the handle became signalled, rather than polling. (Shared handles still have to poll.) * threads.c (_wapi_thread_queue_apc): Interrupt the thread if it's waiting on a handle * handles-private.h (_wapi_handle_current_thread_set_waiting_on): Helper functions to inform the APC queuing functions when threads are waiting for handles, and to interrupt the wait. * wait.c (WaitForMultipleObjectsEx): Need to tell the handle waiting functions if any of the handles in question are shared 2007-06-06 Miguel de Icaza * processes.c (is_managed_binary): Fix for OSX. 2007-06-06 Wade Berrier * atomic.h (InterlockedExchangePointer): cast to pointer to to silence compiler warnings (autobuild fails the build on this type of warning) 2007-05-21 Dick Porter * io-portability.c (_wapi_g_dir_open): Don't propagate any errors from the second call to g_dir_open, preserve the original error if the second call still fails but clear the error if it succeeds. 2007-05-10 Dick Porter * sockets.c (_wapi_recvfrom): Refine the fix to bug 75705 so EINTR isn't returned if the remote end shuts down cleanly. Fixes zmd and the second example in bug 75705. 2007-04-26 Dick Porter * shared.c (_wapi_shm_semaphores_init): Need to check MONO_DISABLE_SHM in this entry point, as it's called before _wapi_shm_attach(). Fixes bug 81436. 2007-04-24 Dick Porter * sockets.c (_wapi_recvfrom, socket_close): Force recvfrom() to error if the socket is closed while the receive is blocking. Fixes bug 75705. 2007-04-13 Dick Porter * shared.h: * shared.c: Complete the reimplementation of disabling of shared memory, by not allocating sysv semaphores when shm disabling has been requested (either at compile time or run time.) * processes.c (CreateProcess): Don't synchronize locking across processes when forking, when shared memory has been disabled. 2007-04-06 Andreas Faerber * wapi_glob.h: * wapi_glob.c: remove reference to sys/cdefs.h, use glib instead. Fixes: 81326 2007-04-05 Dick Porter * io.c: * io-portability.c (_wapi_io_scandir): Moved from io.c, and changed to use a cut-down version of glob(3) that has been extended to match with case-insensitivity if needed. * wapi_glob.h: * wapi_glob.c: Cut down implementation of glob(3), based on OpenBSD. 2007-03-22 Dick Porter * sockets.c (_wapi_connect): Do additional checks when connect(2) fails, because some systems don't let it be restarted. Patch based on one submitted by Robert S Wojciechowski , fixes bug 81010. 2007-03-09 Jonathan Chambers * io-layer.h: Remove UNICODE and _UNICODE defines as these are done by configure.in now. Code is contributed under MIT/X11 license. Thu Mar 8 19:42:17 CET 2007 Paolo Molaro * shared.c: partial support for MONO_DISABLE_SHM env var. 2007-03-05 Wade Berrier * atomic.h: atomic fixes from Michael Matz for for s390 and s390x ( bnc #237611 and bxc #80892 ) 2007-03-05 Miguel de Icaza * io.c (CreateFile): Use FILE_ATTRIBUTE_TEMPORARY to mean 0600 permissions. For 80688 (MoveFile): Use errno_copy here, just to avoid a potential errno-changing code in the future from g_free. Also, ignore EXDEV errors as they are handled immediately after (avoid printing out an error). Fixes: 80655 Mon Feb 12 15:50:24 CET 2007 Paolo Molaro * shared.c: exit if semaphores can't be created (bug #80616). 2007-02-01 Geoff Norton * collection.c: NetBSD doesn't define PTHREAD_STACK_MIN. 2007-01-26 Dick Porter * socket-private.h: * sockets.c (_wapi_getsockopt): Windows seems to not reset SO_ERROR values when they're read, contrary to the documentation. Fixes the new issues raised in bug 79878 (example in C showing winsock behaviour attached to that bug.) 2007-01-15 Mark Mason * sockets.c (_wapi_connect): Don't do the SO_BROADCAST setting here, do it in managed code instead. (_wapi_getsockopt): SO_RCVTIMEO and SO_SNDTIMEO use struct timeval, which has a microsecond field, not milliseconds. (_wapi_setsockopt): ditto. (_wapi_setsockopt): Halve the SO_SNDBUF and SO_RCVBUF values on Linux, as the kernel doubles whatever we set. (_wapi_socket): Save socket domain, type and protocol so it can be duplicated later. (socket_disconnect): Implement socket disconnect (closing the socket, but keeping the file descriptor.) (wapi_disconnectex): A basic implementation of DisconnectEx(). (wapi_transmitfile): A very basic implementation of TransmitFile(). (WSAIoctl): Implement the SIO_GET_EXTENSION_FUNCTION_POINTER ioctl. * socket-private.h (struct _WapiHandle_socket): Record socket domain, type and protocol info so it can be duplicated later. * sockets.h (WSAID_DISCONNECTEX,WSAID_TRANSMITFILE): Structures and defines needed to look up the DisconnectEx() and TransmitFile() functions by GUID. * error.c (errno_to_WSA): Change ETIMEDOUT mapping to WSAETIMEDOUT; add EDESTADDRREQ. * io-layer.h: Need mswsock.h on windows now. 2007-01-04 Miguel de Icaza * io-portability.c (find_file): Fix a coverity warning (scanning being unassigned). 2006-12-31 Miguel de Icaza * io-portability.c (find_file): Do not abort if an empty filename has been passed. This fixes the case where MONO_IOMAP=all would assert if Directory.Exists ("") was called. Mon Dec 18 14:54:37 CET 2006 Paolo Molaro * processes.c: moved a free on the error path. Thu Dec 14 21:42:39 CET 2006 Paolo Molaro * processes.c: fixed a few memory leaks when executing processes. Mon Nov 27 13:12:17 GMT 2006 Paolo Molaro * atomic.h: fix arm compare and exchange (bug #78500). 2006-11-23 Dick Porter * process-private.h (struct _WapiHandle_process): Add 'waited' parameter * processes.c (process_wait): Check the 'waited' parameter not the signalled state when testing if a process has already been waited for, as the child process itself may set signalled when exiting. Fixes bug 79885. * wapi-private.h (_WAPI_HANDLE_VERSION): Bump shared data version * shared.c: Now the shared data version has been incremented we can set the counter semaphore initial value correctly 2006-11-22 Dick Porter * processes.c (process_wait): Cope when the background process reaper gets the process we were waiting for. Special case for waiting for our own process to exit. Fixes bug 77736. 2006-11-17 Dick Porter * processes.c: Fix const correctness and typos that caused memory corruption. 2006-11-17 Miguel de Icaza * processes.c (ShellExecuteEx): Check error after CreateProcess, thanks to Dick for pointing this out. 2006-11-16 Miguel de Icaza * processes.c (ShellExecuteEx): If we fail to create a process in ShellExecute, then try to use the xdg-open command, and if that fails, try to use the gnome-open command, Refactor the code so that we do not have to duplicate all this code, but instead use a ucs2-aware version of the code to do concatenations. 2006-11-13 Dick Porter * io.c (_wapi_stat_to_file_attributes): If the file is a symlink add the FILE_ATTRIBUTE_REPARSE_POINT flag. This is an attempt to follow the specs for the windows symlink support, but will probably have to be reworked when I have test data from a vista machine. Fixes bug 79887. 2006-11-11 Miguel de Icaza * handles.c (CloseHandle): Cope here with the new value INVALID_HANDLE_VALUE set on handles. * processes.c (CreateProcess): Initialize the value of hThread to be INVALID_HANDLE_VALUE on failure, not to be NULL. Improvement for #75733 2006-11-09 Dick Porter * sockets.c (_wapi_select): Do some sanity checking on the fd_sets, to avoid file descriptors > FD_SETSIZE. (_wapi_FD_CLR, _wapi_FD_ISSET, _wapi_FD_SET): Avoid file descriptors > FD_SETSIZE. 2006-10-27 Dick Porter * io.c (GetFileAttributes): Force symlinks to directories to be returned as a regular file. Fixes bug 79733. 2006-10-18 Miguel de Icaza * io-portability.c (find_in_dir): First string dup, then closedir. 2006-10-12 Dick Porter * processes.c (_wapi_process_reap): Unref a process handle if we reaped it, found by Zoltan. Fixes bug 79286. (process_wait): Don't wait again if we've already waited for a process. 2006-10-11 Sergey Tikhonov * atomic.h: Fix atomic decrement. * mini/cpu-alpha.md: Use native long shift insts * mono/mono/mini/tramp-alpha.c: Implemented mono_arch_patch_delegate_trampoline method * Started work on using global registers * Use byte/word memory load/store insts if cpu supports it * Code clean up 2006-10-09 Zoltan Varga * handles.c (timedwait_signal_poll_cond): Add an alertable parameter, and if it is FALSE, avoid busy waiting. * wait.c: Add an alertable parameter to the wait routines. 2006-10-06 Miguel de Icaza * io-portability.c (find_file): Rename from MONO_IO_PORTABILITY_HELP to MONO_IOMAP. 2006-10-03 Dick Porter * io-portability.h: * io-portability.c: Optional portability helpers and wrapped system calls to try to cope with windows filenames in applications. * io.c: Use the wrapped system calls 2006-09-01 Zoltan Varga * critical-sections.h critical-sections.c: Make Enter/LeaveCriticalSection a macro since they are perf critical. * atomic.h: Applied patch from Jakub Boqusz . Add atomic ops implementation for alpha. 2006-08-11 Dick Porter * processes.c (_wapi_process_reap): Avoid a deadlock by setting process termination details in an outer loop, not the _wapi_search_handle() one. 2006-08-10 Dick Porter * threads.c (_wapi_thread_queue_apc) (_wapi_thread_dispatch_apc_queue): Use a process-local mutex here instead of the cross process semaphore. We already check that access to the APC queue is within the owning process so there's no need to protect from other processes. Avoids a global deadlock when a thread is aborted while it holds the handle semaphore locked. (_wapi_thread_apc_pending): Hide an annoying message which can happen if a thread handle has been blown away at process shutdown while it is in an alertable wait. Both problems seen while shutting down monodevelop. 2006-07-25 Dick Porter * shared.c (_wapi_shm_file): Remove '/' characters from the uname results. Fixes bug 78917. 2006-07-20 Dick Porter * threads.c (_wapi_thread_set_termination_details): Improve the test for already-disposed thread handles, and hold the lock around the mutex abandoning. 2006-07-17 Dick Porter * processes.c (CreateProcess): Don't change directory unless a new one has been specified. Fixes bug 78751. 2006-07-06 Dick Porter * io.c (_wapi_stat_to_file_attributes): Do a better job at figuring out the file attributes (_wapi_set_last_path_error_from_errno): New helper function to turn errno into w32 error codes that handles the differences between file and directory errors (file_setendoffile): Try turning off the extra write used to extend files, because we probably don't need it on any modern platform. If it is needed though, we also need to lseek the file position back again (CreateFile): Treat character-special devices as a console handle, because they can't be seeked (CopyFile): If fail_if_exists is set, then the destination needs to be opened with O_EXCL (CopyFile): If fail_if_exists is not set and the destination already exists, then we should set the ERROR_ALREADY_EXISTS error even though we return success (stdhandle_create): STD_INPUT_HANDLES cannot be written to (GetStdHandle): Rework without using mono_once, so console handles can be properly closed and reopened. (mono_io_scandir): Only override errno with EACCES when the directory actually exists (FindFirstFile): Set ERROR_FILE_NOT_FOUND when no files are returned (FindClose): Cope with NULL handles (CreateDirectory): When the target already exists, just return an error. It's the caller's job to figure out what to do. (SetCurrentDirectory): Cope with a NULL path (RemoveDirectory, GetFileAttributes, GetFileAttributesEx, SetFileAttributes, FindFirstFile, DeleteFile, MoveFile, CopyFile, CreateFile): Set path error correctly * handles.c (CloseHandle): Kludge to try and cope with passing a NULL handle * error.h: Add NO_ERROR as an alternative to ERROR_SUCCESS * uglify.h: Added some more typedefs 2006-07-05 Dick Porter * io.c (GetFileAttributes, GetFileAttributesEx): Cope with dangling symlinks. Fixes bug 78664. 2006-06-23 Dick Porter * handles.c (handle_cleanup): * threads.c: Clean up threads properly when we're forcibly removing the handle entries from the shared file in handle_cleanup(). Fixes bug 78241, for real this time. 2006-06-15 Neale Ferguson * atomic.h: More tinkering with InterlockedExchange/InterlockedCompareExchange for s390/s390x. 2006-06-14 Neale Ferguson * atomic.h: Fix atomic exchange pointer operations for s390x - these were broken as they used 32-bit instructions rather than their 64-bit versions. 2006-06-14 Dick Porter * processes.c: Don't run the atexit handlers when bailing out of a fork/exec. 2006-06-14 Dick Porter * wait.c: Fix stupid typo shown up by gcc 4.1.1, = not == * handles-private.h: * shared.c: * io.c: * processes.c: * mono-spinlock.h: * handles.c: * collection.c: Fix a bunch of signed/unsigned warnings from gcc 4.1.1 2006-06-09 Neale Ferguson * atomic.h: Fix atomic operations for s390x (not really broken but changed to use full 64-bit opcodes). 2006-05-24 Dick Porter * processes.c (process_set_current): Don't take an extra reference if we have to create our own process handle. Fixes bug 78241 again. * threads.c (_wapi_thread_signal_self): Renamed from _wapi_thread_abandon_mutexes, also sets the thread state to signalled and drops a reference. Called by the runtime when the main thread cleans itself up. * handles.c (handle_cleanup): As a last resort, unref every shared handle as the process is now exiting. 2006-05-16 Dick Porter * processes.c (process_set_termination_details): Unref the handle when we've stored the exit details. Fixes the rest of 78241. 2006-05-12 Dick Porter * threads.c: Implement pseudo handles, making GetCurrentThread() match MS behaviour. Notice when attached threads exit, and unref the handle. Fix usage of GetCurrentThread() in other places. * handles.c (DuplicateHandle): Implement a basic form of DuplicateHandle(). * wait.c: Fix usage of GetCurrentThread() throughout, and cope with pseudo handles. 2006-04-26 Miguel de Icaza * io.c (file_close): Oops, do not use DeleteFile which expects unicode, instead use unlink directly Add support for the new FileOptions bits on .NET 2.0. It might be good if Dick reviews these changes. * io.c (file_close): If DeleteOnClose is set, then delete the file before freeing it. (CreateFile): Do not support encryption per user. If posix_fadvise exists, pass hints on sequential scan and random access. Did not figure out what WRITE_THROUGH maps to. 2006-04-26 Dick Porter * sockets.c (WSAIoctl): Check the output buffer is valid before writing to it. * handles.c (_wapi_search_handle): Set shared pointer if we find a shared handle that has been already opened. 2006-04-21 Dick Porter * threads.c (GetCurrentThread): Reference the handle if we return an already-known thread. 2006-04-07 Dick Porter * processes.c: Fix build for older glib. 2006-04-06 Dick Porter * processes.c (CreateProcess): Add a reference to the child process' handle, so it won't be destroyed if this process closes its copy of the handle. Fixes bug 77393. * processes.c (process_set_current): Fall through to creating a new one if the handle lookup fails. * processes.c (_wapi_process_signal_self): * handles.c (handle_cleanup): The process is exiting, so set the handle state for this process to signalled. This should let other non-related processes wait for this handle. * handles.c (_wapi_search_handle): Don't search shared handles in all cases. * collection.c (collection_thread): No need to do a collection scan straight away, do the waiting first. 2006-04-06 Dick Porter * shared.c: Fix parameters in semctl () call. 2006-03-28 Zoltan Varga * atomic.h atomic.c: Applied patch from David S. Miller : Reimplement Interlocked* primitives on sparc using CAS/CASx when __GNUC__, else we will fall back to the generic pthread version. 2006-03-27 Dick Porter * shared.c (_wapi_shm_file_open): Break out of a loop if the shared file is smaller than expected. (We loop a few times in case another process is in the middle of creating the file.) 2006-03-22 Dick Porter * handles.c: * wapi-private.h: * shared.h: * shared.c: Delete the semaphores and shared files when the last process has finished with them 2006-03-15 Dick Porter * events.c: * io.c: * mutexes.c: * processes.c: * semaphores.c: * sockets.c: * threads.c: Explicitly initialise the handle ops struct 2006-03-14 Dick Porter * handles-private.h: * wapi-private.h: * wait.c: * handles.c: Add a 'prewait' stage to the handle waiting, to give waiting threads a chance to check for bogus states before blocking. * mutexes.c (namedmutex_prewait): Use the prewait stage to check for named mutexes that have been abandoned in a locked state (eg if a process exited abnormally while owning the mutex) and override it if needed. 2006-03-08 Gonzalo Paniagua Javier * wait.c: speed up WaitFor* when the timeout is 0. 2006-03-03 Dick Porter * processes.c (ShellExecuteEx): Cope when some of the parameters are NULL. 2006-02-27 Dick Porter * mutexes.c: * mono-mutex.c: * threads.c: Comparing pthread_t with == is not portable, so use pthread_equal(). Thu Feb 23 18:47:20 GMT 2006 Paolo Molaro * *.h, *.h: patch from Dick to make Linuxthreads systems work again. 2006-02-22 Dick Porter * thread-private.h: * threads.c: There's no need to use the timed-thread support code any more, as we aren't using the timed join. This greatly simplifies thread setup, and fixes a memory leak (bug 77521). Don't bother to store thread IDs in a hash table, use TLS instead. The one case that needs to look up the handle of a different thread (OpenThread()) can do the extra work itself. Fixes bug 77536. * handles.c (_wapi_search_handle): Add a reference when returning a private handle (shared handles are already reffed.) 2006-02-17 Dick Porter * handles-private.h: * handles.c: Check handle values passed to array lookups. Fixes bug 77572. 2006-02-09 Dick Porter * threads.c: Cope with the problems caused by attaching already existing threads - they don't get the infrastructure to clean up after themselves, especially the ID to handle hash. This fixes bug 77468. 2006-02-06 Gonzalo Paniagua Javier * shared.c: use MONO_SHARED_HOSTNAME as a substitute for gethostname() when creating the shared files in the .wapi directory. Fixes bug #77371. 2006-02-02 Martin Baulig * threads.c: Removed the `WITH_INCLUDED_LIBGC' section; it has never been used so far. * timed-thread.h (TimedThread): Removed the `stack_ptr' field; it has only been used by the removed code. 2006-01-03 Neale Ferguson * atomic.h: Correct s390x definitions and eliminate compiler warnings. 2006-01-03 Sebastien Pouliot * io.c: Patch _wapi_stat_to_file_attributes against bug #76966, where sockets could be considered as directory. 2005-12-23 Dick Porter * semaphores.h: * semaphores.c: Implement OpenSemaphore * mutexes.c: * mutexes.h: Implement OpenMutex * wapi-private.h: * handles.c: * events.c: * events.h: * event-private.h: Implement named events. Implement OpenEvent. 2005-12-15 Dick Porter * processes.c (CreateProcess): The pipe-based cross-process exclusion technique was trying to write NULL buffers when appname was NULL (eg when coming from ShellExecuteEx,) which usually succeeded even though EFAULT was returned - but sometimes it failed. This meant that the child process could block forever on the pipe read. Replace it with the simpler shared handle semaphore protection used everywhere else. This showed up with the test case in bug 76684. Tue Dec 13 11:41:49 GMT 2005 Paolo Molaro * shared.c: fallback to private mmap when shared mmap doesn't work (like on jffs). 2005-12-06 Dick Porter * wapi-private.h: * handles.c: * semaphore-private.h: * semaphores.c: Implement named semaphores 2005-11-24 Dick Porter * processes.c (GetProcessId): Implement GetProcessId() 2005-11-17 Dick Porter * processes.h: * processes.c: Implement ShellExecuteEx as a wrapper around CreateProcess. 2005-11-11 Dick Porter * threads.c: Give mutex abandoning its own exported function, so it can be called when the runtime is cleaning up. * handles.c (_wapi_search_handle_namespace): Do a handle collection befre starting to check namespace strings, so that any stale cruft gets removed. 2005-11-11 Dick Porter * threads.c: Move thread handles back into the shared space. * handles.c (_wapi_handle_unref): Add support for shared handles with close() handlers 2005-11-04 Dick Porter * sockets.c (ioctlsocket): Use select instead of if to avoid a type promotion problem on 64bit freebsd. Based on patch by Lou Kamenov , fixes bug 76447. 2005-11-04 Dick Porter * io.c (file_write): Only do the file locking if MONO_STRICT_IO_EMULATION is set. 2005-10-21 Dick Porter * processes.c: * handles.c (_wapi_lookup_handle): Cope when the shared part of a handle has been deleted. (_wapi_handle_unref): And when the deleted shared part is pointed to as a handle is deleted 2005-10-20 Dick Porter * processes.c (process_set_current): If the expected process handle slot doesn't contain the correct pid, create a new handle. * handles.c (_wapi_search_handle): When the search doesn't find anything, return failure instead of the last handle we looked at. (_wapi_handle_ref, _wapi_handle_unref): Don't try to ref or unref unused handles (makes tracking refcounting bugs easier.) 2005-10-19 Dick Porter * handles.c: * handles-private.h: * wapi-private.h: * processes.c: * mutexes.c: * collection.c (_wapi_handle_collect): Remove the shared handle indirection layer, and use locking instead. Delete other complexity that is no longer needed. Refcount shared handles and delete them when needed, but keep the timestamps so that orphaned handles will be cleaned up eventually. * shared.c (_wapi_shm_file): Add processor, OS and struct size info to the shared file names, to cope with dual-boot and 32/64bit size issues. Fixes bug 75839. * wait.c (WaitForMultipleObjectsEx): No need to distinguish between shared handles and private, as the wait functions cope with both together now. 2005-10-11 Gonzalo Paniagua Javier * io.c: removed NO_SIGPIPE macro. * sockets.c: no need for MSG_NOSIGNAL or ignoring SIGPIPE. 2005-10-11 Dick Porter * sockets.c (_wapi_getsockopt): Translate SO_ERROR results into w32 error codes. * error.c (errno_to_WSA): Don't return a bogus error if someone asks to translate errno 0. 2005-10-11 Dick Porter * handles.c: Fix several race conditions 2005-10-11 Miguel de Icaza * io.c: no need to block SIGPIPE anymore, as it is ignored. 2005-10-05 Dick Porter * threads.c (_wapi_thread_own_mutex, _wapi_thread_disown_mutex): Keep a reference to mutexes owned by threads, so they won't be destroyed prematurely. Fixes dotmsnclient crash. 2005-09-26 Sebastien Pouliot * io.c: Apply patch from #76192 (Can't write files past 2gb on AMD64 (x86_64)) for Brion on IRC (Dick approved it). 2005-09-23 Dick Porter * processes.c: Don't wait for processes that have already been signalled; also fix typo. * handles.c: Improve locking inside new handle and handle searching functions. 2005-09-20 Dick Porter * collection.c: * processes.c: Periodically waitpid for known process IDs. Fixes bug 74870. 2005-09-15 Gonzalo Paniagua Javier * io.c: (CreateFile): if the file is a named pipe, treat the handle as a pipe, not as a file. Fixes bug #76075. 2005-08-27 Zoltan Varga * atomic.h: Add support for intel icc. 2005-08-25 Zoltan Varga * io-layer.h: Include winbase.h not WinBase.h. 2005-08-19 Dick Porter * threads.c, threads.h, thread-private.h: Use a gsize to store the thread ID, so it can hold a 64 bit value if needed. 2005-07-26 Gonzalo Paniagua Javier * error.c: map ENOENT to WSAECONNREFUSED. It might happen when connecting to unix sockets. Closes bug #75632. 2005-07-05 Dick Porter * io.c: Make sure SIGPIPE is ignored when calling write(2). Prevents the runtime exiting when writing to a closed pipe, fixing bug 75468. 2005-06-30 Dick Porter * shared.c (_wapi_shm_semaphores_init): Add some helpful error messages when semget () fails due to lack of resources. 2005-06-21 Dick Porter * mutex-private.h: * thread-private.h: * mutexes.c: * threads.c: Keep a list of owned mutexes in each thread handle, so that it is easier to abandon them when the thread exits. Removes a bottleneck when multiple threads are finishing in parallel. 2005-06-12 Gonzalo Paniagua Javier * io.c: (GetLogicalDrives) when a bogus line is read, don't leak memory. When the buffer has not enough space, close the file before returning. 2005-06-09 Duncan Mak * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to all public headers. Fixes #74919. 2005-05-30 Zoltan Varga * atomic.h: Add IA64 atomic ops. 2005-05-26 Gonzalo Paniagua Javier * processes.c: make ExitCode be valid even if the user didn't call WaitForExit() and is just polling on HasExited. 2005-05-17 Dick Porter * io.c (file_getfilesize): Clear the error value, so that files with sizes with the low bits 0xFFFFFFFF can be distinguished from a genuine error. 2005-05-11 Gonzalo Paniagua Javier * shared.c: forgot to ignore a warning. 2005-05-10 Gonzalo Paniagua Javier * shared.c: don't display warnings after reboots. 2005-05-07 Gonzalo Paniagua Javier * sockets.c: on windows, getsockopt/setsockopt for send/receive timeout use an integer in milliseconds. We were using a struct timeval. 2005-05-06 Dick Porter * handles-private.h: * mutexes.c: * wapi-private.h: * shared.h: * shared.c: * wait.c: * handles.c: * collection.h: Use SysV semaphores for managing access to the shared memory - in return for the ludicrous api we get synchronisation primitives that can be cleaned up by the kernel even when a process quits unexpectedly. This removes the timestamp issues. 2005-05-05 Lluis Sanchez Gual * handles.c: Always use polling in the waits, since mono_cond_timedwait can't be interruped by the thread abort signal. 2005-04-30 Gonzalo Paniagua Javier * events.c: calling Set on AutoResetEvent several times has the same effect as calling it only once if no thread is waiting for it. 2005-04-29 Dick Porter * processes.c (EnumProcesses): Use a GArray instead of a GPtrArray now it's storing pids not handles, also fixes memory leak caused by unclear glib documentation. * sockets.c (WSACleanup): Remove unused variable 2005-04-29 Dick Porter * handles.c (_wapi_handle_check_share_by_pid): For systems that don't have file descriptor info in /proc check that the original opener of a file is still there, if a share violation would otherwise happen. 2005-04-28 Gonzalo Paniagua Javier * handles.c: * handles-private.h: added _wapi_handle_forecch that loops through all the handles and call a callback function when a handle of the given type is found. * sockets.c: no need to keep open sockets in an array, as we have them in the handles structure. Fixes bug #74755. 2005-04-28 Dick Porter * processes.c: Cope with handles that are only around for as long as the search is running. If we're searching for process handles, check to see if the process is still running and signal it if not. * handles.c (_wapi_search_handle): Search in the shared space as well. Fixed bug 74752. * mutexes.c: * handles.c (_wapi_handle_new_from_offset): _wapi_handle_new_for_existing_ns () was doing exactly the same as this, so deleted it. 2005-04-26 Dick Porter * handles.c: Fix stupid thinko where if a new shared handle is created but a collection was needed to free some space, it returned an error anyway. Should fix the messages shown in bug 74659. 2005-04-25 Dick Porter * handles.c (_wapi_handle_check_share): Only consider mono processes when looking to see if a file is still being held open, while checking share permissions. 2005-04-25 Dick Porter * sockets.c: * io.c: * wapi-private.h (struct _WapiHandleOps): * handles.c (_wapi_handle_unref): When destroying handles, save the handle data and call the close function only after the array slot has been cleared. This prevents race conditions with file descriptors, fixing bug 74713. * mutexes.c: Delete the handle close functions, they didn't do anything anyway * error.c (_wapi_get_win32_file_error): Add a mapping for EINTR so the "Unknown error" g_warning doesn't get displayed. 2005-04-25 Dick Porter * wapi-private.h: * threads.c: Make thread handles process-private for now to take some of the space pressure off the shared memory, while I work on a real fix. 2005-04-21 Dick Porter * handles.c (_wapi_handle_check_share): Make sure there is a "fd" dir in /proc before blowing away handle info. Fixes bug 74649. 2005-04-21 Dick Porter * wait.c (WaitForMultipleObjectsEx): Implement special waits * handles.c (_wapi_handle_wait_signal_poll_share): Don't return a timeout, just wait briefly for the private signals and let the waiting thread test again. This prevents us missing shared signals. 2005-04-21 Dick Porter * collection.h (_WAPI_HANDLE_COLLECTION_EXPIRED_INTERVAL): Reduce the time before a slot is considered too old and deleted. This is a workaround while I come up with a proper fix. 2005-04-21 Dick Porter * mutexes.c: * processes.c: * threads.c: * handles.c (_wapi_handle_new): Turn assertions into errors. * collection.c (_wapi_handle_collect): Use symbols not magic numbers for timeout values 2005-04-19 Dick Porter * mutexes.c: * wait.c: * handles.c (_wapi_handle_count_signalled_handles) * handles-private.h (_wapi_handle_shared_lock_handle): Use new shared handle locks in critical sections. * handles.c (_wapi_handle_new_for_existing_ns): Reuse old handles if there is already one there. * handles.c (_wapi_handle_ref): It was possible for a process to exit before getting around to updating shared handle timestamps, so do it here too. Tue Apr 19 16:25:47 CEST 2005 Paolo Molaro * threads.c: fix lookup of the thread id in the has table: always use the id value, not the pointer to the id. 2005-04-18 Gonzalo Paniagua Javier * handles.c: fix handle returned in _wapi_handle_search_handle. Dick pointed it out. 2005-04-16 Gonzalo Paniagua Javier * io-layer/sockets.c: FIONBIO with a TRUE argument means we want non-blocking IO, not the other way around. 2005-04-16 Gonzalo Paniagua Javier * handles.c: * io.c: * handles-private.h: GetFileType wasn't checking if we have memory allocated for the handle before dereferencing it. Fixes a FileStream nunit test. 2005-04-16 Gonzalo Paniagua Javier * handles.c: * processes.c: * handles-private.h: we were calling g_renew to expand the handle array, but that might move the memory and we might have pthread conditions or mutexes in the original memory area that are being used. Now instead of expanding an existing array, we just create new ones and keep a list of them. Access to _wapi_private_handles had to be modified accordingly. 2005-04-15 Dick Porter * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN 2005-04-14 Raja R Harinath * wapi-private.h: Remove reference to 'daemon-private.h'. Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro * atomic.h: applied patch from mass@akuma.org (David Waite) to fix InterlockedExchangeAdd. Fixed a few other functions, including InterlockedCompareExchange() which was miscompiled by gcc with optimizations enabled. 2005-04-13 Dick Porter * io.c (share_check): * handles.c (_wapi_handle_check_share): Refine the file check so that sharing violations within the same process don't cause assertion failures. 2005-04-13 Dick Porter * io.c (FindFirstFile): Fix bugs introduced with the merge (bug 74586) 2005-04-12 Dick Porter The daemon-less io-layer. Extensive lowlevel changes in handles.c, requiring some corresponding changes in other files calling these functions. Private_foo structures have been eliminated. File descriptor handling differences account for most of the changes in io.c and sockets.c. Other highlights: * mutexes.c: Named mutexes are now a distinct type. * atomic.h: Fix a PPC uninitialised variable warning. * wait.c: Check conditions before waiting on a condition variable. * processes.c: Handle process fork and wait without a daemon (though this has the limitation of only being able to wait for child processes.) 2005-04-07 Gonzalo Paniagua Javier * io-private.h: * threads.c: * threads.h: * io.c: * sockets.c: * sockets.h: removed dead code that deals with async IO. 2005-03-30 Zoltan Varga * atomic.c (InterlockedIncrement): Fix fallback implementation of InterlockedIncrement and InterlockedDecrement. Fixes #74228. 2005-03-29 Sebastien Pouliot * io-layer.h: Add required header files for compiling with VS.NET. 2005-03-17 Miguel de Icaza * io.c: don't fail on NFS when there are no more locks available. 2005-03-09 Dick Porter * error.c (_wapi_get_win32_file_error): ENFILE and EMFILE should map to ERROR_TOO_MANY_OPEN_FILES, not ERROR_NO_MORE_FILES. Fixes bug 72671. 2005-03-09 Dick Porter * daemon.c (process_process_fork): Initialise the handle data before using it in the error case. This is probably the error we're working around in the previous change. Spotted by Taru Jain and Hemanth Yamijala . 2005-03-07 Dick Porter * daemon.c: It looks like g_shell_parse_argv() can return argv[0]=NULL somehow, yet still not give an error. Make sure we don't pass NULL to strrchr(), working around a segfault that showed up on ZLM testing. 2005-03-01 Gonzalo Paniagua Javier * sockets.c: translate EINPROGRESS to EWOULDBLOCK in connect. This is the expected error code showed by the test case in bug #73053. 2005-02-18 Gonzalo Paniagua Javier * io.c: another leftover. Fri Feb 18 17:37:29 CET 2005 Paolo Molaro * io.c: fixed logic in checking errno in rev 40815. Fri Feb 18 16:00:29 CET 2005 Paolo Molaro * threads.c: we don't depend on the GC checking tls slots anymore. * processes.c: remove unused ref to GC headers. Thu Feb 17 19:57:11 CET 2005 Paolo Molaro * io.c: remove _wapi_thread_cur_apc_pending () checks when the siscall should return immediatly and handle the case when a syscall is interrupted without erroring out, but returning a 0 read/write if possible. Still the cases of read from file need to be handled. Tue Feb 8 18:28:11 CET 2005 Paolo Molaro * threads.c: make people test with 1 MB stack per thread. 2005-01-17 Dick Porter * timefuncs.h: Make WapiFileTime endian-aware, as it's often cast to and from 64bit ints. Fixes bug 71213. 2005-01-11 Dick Porter * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code translation. Mon Jan 10 16:15:19 EST 2005 Neale Ferguson * atomic.h: Fix functions on s390. Mon Jan 10 20:30:19 CET 2005 Paolo Molaro * atomic.h: fix some functions on ppc (tests/interlocked.cs). 2005-01-10 Dick Porter * misc.c (_wapi_calc_timeout): Guard against overflow when calculating timeouts. This makes waiting with a large (Int32.MaxValue) timeout not return immediately. 2004-12-23 Ben Maurer * io.c (io_ops): make this `const' so it is shareable (well, only really shareable if it is statically linked...) Mon Dec 20 11:58:33 CET 2004 Paolo Molaro * threads.c, threads.h: add accessor to get the pthread_key_t for a tls id. 2004-12-13 Gonzalo Paniagua Javier * io.c: check for the existence of 'dest' and set ERROR_ALREADY_EXISTS if it exists and is not the same as 'src'. 2004-12-01 Neale Ferguson * atomic.h : Fix InterlockedCompareExchange for s390/s390x. 2004-12-01 Gonzalo Paniagua Javier * processes.c: unquote the cmd path, allow for ' or " when quoting and pass the quoted program name to the daemon, otherwise the call to g_shell_unquote in the daemon will break things up. 2004-10-14 Dick Porter * sockets.c (_wapi_accept): Revert the previous change. We now set the accepted socket to have the same blocking status as the listening socket in managed code. This follows MS behaviour. 2004-10-14 Dick Porter * sockets.c (_wapi_accept): On Darwin, make sure a newly accept()ed socket is blocking. Fixes bug 67355, patch by grompf@sublimeintervention.com. 2004-10-04 Gonzalo Paniagua Javier * system.c: check the number of online processors instead of the existing ones. Sanitize return value if it's an error. 2004-10-03 Ben Maurer * system.c: Add support for getting the # of cpus. 2004-09-28 Dick Porter * io.c (pipe_close_private): Fix one small typo in the last change that totally hosed process creation with redirected pipes. 2004-09-24 Dick Porter * wapi-private.h: * sockets.c: * socket-private.h: * io.c: * io-private.h: * handles-private.h: Cope when a file descriptor is reused while the handle that thought it owned it is still referenced, instead of asserting. Probably fixes bug 66479, though we've been unable to reproduce it. 2004-09-09 Dick Porter * error.c: * io.c: Set error codes everywhere. 2004-09-06 Dick Porter * handles.c (_wapi_handle_unref): Reset the private record's type (CloseHandle): Check for a fd mapping failure, and return FALSE. (_wapi_handle_process_fork): Fix long-standing bug in checking handle return values. Also do the required bookkeeping with the new process's handles. * daemon.c: When creating a new process's handles, check whether the shared space needs to be increased 2004-09-05 Zoltan Varga * shared.c (_wapi_shm_file): Fix leaking of filename. 2004-08-19 Dick Porter * handles.c (_wapi_handle_count_signalled_handles): Fix thinko introduced with the fd offset stuff: unlock handles properly when backing off. Fixes the monologue hang at exit. 2004-08-18 Dick Porter * sockets.c: * io.c: Check that new fds fit in the table, return error if not * daemon.c (_wapi_daemon_main): * handles.c (shared_init): Have all processes agree on a size for the fd table. 2004-08-17 Dick Porter * daemon.c (process_new): * handles.c (_wapi_handle_new_internal): Cope when the space reserved for file descriptors is larger than the shared segment size. Fixes the crash reported when running mono under gdb on macosx. 2004-08-16 Dick Porter * sockets.c: * io.c: * handles-private.h (_wapi_handle_fd_offset_to_handle): Improve error checking with passed-in file descriptors. 2004-08-11 Dick Porter * sockets.c: * io.c: Returned handle values are the file descriptor the handle encapsulates * handles.c: * handles-private.h: * daemon.c: Reserve the range of handles that can have the same values as file descriptors. These won't be used, but the values will be used as file, console, pipe or socket handles. The fd to handle mapping is done internally and is invisible to users. Fixes bug 61828. * wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now reserve a chunk of handle space. 2004-08-04 Neale Ferguson * atomic.h: add support for 64-bit S/390 2004-07-22 Dick Porter * timed-thread.c: * threads.c: Move the destruction of the internal thread data to after the thread has been joined. Fixes bug 61418. 2004-07-14 Dick Porter * wait.c (test_and_own): When not waiting for all handles to become signalled, only own and return the lowest. All the documentation suggests that the old way was correct, but experimentation shows it actually works like this. Patch by Sébastien Robitaille (sebastien.robitaille@croesus.com), fixes bug 61511. 2004-07-09 Ben Maurer * threads.c: register roots for gc 2004-07-08 Dick Porter * io.c (file_seek): If there is a high 32bit offset part, make sure the low part isn't sign-extended. Set error codes when returning failure. Fixes bug 61131. 2004-07-06 Dick Porter * io.c (file_setfiletime): Check for underflow when converting to time_t values. Set error codes when returning failure. Fixes bug 60970. 2004-07-05 Dick Porter * mutexes.c (mutex_ops_init): Make the named mutex mutex sharable. * daemon.c (unref_handle): Only destroy a handle if all processes have released it, not just the current one. Fixes bug 60887. 2004-06-30 Zoltan Varga * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions to prevent warnings. 2004-06-24 Dick Porter * mutexes.c: Indicate when a named mutex was reused 2004-06-24 Dick Porter * threads.c (SuspendThread): * timed-thread.c (_wapi_timed_thread_suspend): Wrap sem_wait in a while loop. See bug 58161. Wed Jun 23 23:29:04 CEST 2004 Paolo Molaro * io.c: don't use sharemode for on-disk file permissions: it's used for shared access to the open file. 2004-06-22 Dick Porter * events.c (CreateEvent): When creating an auto-reset event that is initially owned, make sure the set count starts at 1. 2004-06-18 Dick Porter * event-private.h: * events.c: Auto-reset events need to release one thread for each time SetEvent() is called. Fixes bug 41292. * threads.h: * mutex-private.h: * mutexes.c: Scan for mutexes that are still locked by a thread when it exits. Fixes the MS demo app linked by bug 41292. * wait.c (test_and_own): Make sure a handle is signalled before it is owned. 2004-06-16 Dick Porter * timed-thread.c: Call the thread cleanup exit routine before taking the join mutex, because this could deadlock if another thread tries to join in the meantime. This fixes the hang-at-exit problem seen on macos. 2004-06-03 Lluis Sanchez Gual * threads.c: Implemented SleepEx. * threads.h: Fixed SleepEx signature. 2004-06-03 Miguel de Icaza * threads.c: When running under valgrind, do not allocate too much stack, as Valgrind default is 1 meg. 2004-05-27 Dick Porter * io.h: * io.c: Implemented LockFile() and UnlockFile() 2004-05-21 Dick Porter * io.c (CreateFile): Check for existing share modes when opening a file. * handles.c: * handles-private.h: * daemon-messages.h: * daemon.c: Maintain a hash of file share modes, keying on device and inode (to cope with symlinks.) 2004-05-20 Lluis Sanchez Gual * daemon-messages.c: Retry if the communication with the daemon is interrupted by a signal. * io.c, sockets.c: Check for EINTR in every syscall that can be interrumped. Only return an error in this case if there is something in the apc queue (which means that it is an interruption requested by the "user"). * processes.c: Use WaitForSingleObjectEx. No need to pass "alertable" as true since the wait is small. * shared.c: Retry write calls when interrumped by a signal. * timed-thread.h, timed-thread.c: added _wapi_thread_apc_pending, which returns TRUE if there are pending asynchronous calls (APC) for the provided thread. Also added _wapi_thread_dispatch_apc_queue which calls the enqueued APCs. Defined a new struct ApcInfo that holds information about an enqueued APC. * thread-private.h, threads.c: Implemented QueueUserAPC (which does the same as in win32),_wapi_thread_apc_pending and _wapi_thread_dispatch_apc_queue. These last two methods call the corresponding apc methods in thread-private using the provided thread handle. * threads.h: Added QueueUserAPC. * uglify.h: Added WapiApcProc (needed by QueueUserAPC). * wait.c, wait.h: Changed WaitForSingleObject to WaitForSingleObjectEx, and WaitForMultipleObjects to WaitForMultipleObjectsEx. Implemented support for APCs in those two methods and also in SleepEx. 2004-05-17 Dick Porter * io.c (CopyFile): Speed up. Fixes bug 57859. 2004-05-13 Dick Porter * mono-mutex.c (mono_mutex_unlock): Return EPERM when the current thread doesn't own the mutex, rather than assert()ing. 2004-05-11 Dick Porter * shared.c (_wapi_shm_attach): Cope when a previous daemon startup attempt failed, leaving shared files that look like a daemon is still starting. 2004-05-10 Gonzalo Paniagua Javier * io.c: (SetFileAttributes): don't the the exec bit if the corresponding read bit is not set. 2004-05-10 Zoltan Varga * io.c (FindFirstFile): Fix invalid free. 2004-05-09 Gonzalo Paniagua Javier * io.c: translate from GFileError to errno codes and don't free variables right after calling mono_io_scandir, as we may overwrite errno value. 2004-05-08 Gonzalo Paniagua Javier * io.c: g_dir_open return ENOENT for directories on which we don't have read/execute permission, while returning EPERM for anything below those. So, change ENOENT by EPERM if the directory exists. 2004-05-07 Dick Porter * io.c (SetFileAttributes): Don't have failed chmod()s cause a "file not found" error. Fixes bug 54032. 2004-05-07 Dick Porter * io.c (FindFirstFile): Comment out a windows-compatibility check that breaks when directories have metachars in their names. Workaround for bug 58116. 2004-05-06 Gonzalo Paniagua Javier * io.c: fixed for FindFirstFile for empty directories. Closes bug #58147. 2004-05-06 Gonzalo Paniagua Javier * processes.c: set the start time for the current process. Fixes bug #58109. 2004-05-06 Gonzalo Paniagua Javier * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find. * io.c: implemented scandir using glib functions. 2004-05-04 Dick Porter * daemon.c (read_message): Return FALSE on error so the GSource callback itself can return FALSE. Cures the infinite loop poll() warning on MacosX. * shared.c: Fix some daemon startup race conditions. 2004-04-29 Miguel de Icaza * io.c (CopyFile): Use 32k buffers to copy the file instead of 2k, use the stack, do not use dynamic memory. 2004-04-29 Zoltan Varga * io.c: Add scandir implementation for platforms which do not have it, like solaris. 2004-04-29 Gonzalo Paniagua Javier * io.[ch]: implemented GetLogicalDriveStrings. 2004-04-29 Gonzalo Paniagua Javier * io.c: * sockets.c: use the field name from configure when accessing sigval pointer field. Makes this work on the Mac. 2004-04-28 Bernie Solomon * atomic.c: (InterlockedExchange) fix typo for mutex name 2004-04-28 Gonzalo Paniagua Javier * io.c: * sockets.c: added check for sys/aio.h. 2004-04-28 Gonzalo Paniagua Javier * error.[ch]: added _wapi_get_win32_file_error... * io.c: ... which was _wapi_get_win32_error here. * sockets.c: rename the function calls here too. 2004-04-28 Dick Porter * daemon-messages.c: Avoid a deadlock when a thread is killed while waiting for the daemon by using a recursive mutex. Helps bug 56699. 2004-04-28 Gonzalo Paniagua Javier * io.c: fixed leak in async_notifier(). * sockets.[ch]: added AIO support for sockets and fixed WSAIoctl declaration. * threads.c: removed old comment. 2004-04-26 David Waite * daemon-messages.h: * daemon-private.h * error.h: * io.h: * processes.h: * shared.h: * thread-private.h: * wapi-private.h: remove comma from end of enumeration declarations * status.h: cast unsigned int types to int for enum assignment 2004-04-26 David Waite * io.c: * timefuncs.c: declare 64-bit constants as long long types (i.e. 10ULL) 2004-04-24 Gonzalo Paniagua Javier * socket-wrappers.h: _wapi_socket == WSASocket now. Added WSA_FLAG_OVERLAPPED. * sockets.c: new unused parameters for _wapi_socket. 2004-04-22 Miguel de Icaza * timed-thread.c: Replace sem_init with MONO_SEM_INIT to handle the fact that MacOS X is a piece of junk (sem_init is *defined* in the libc, but they return `not implemented'). 2004-04-22 Dick Porter * handles.c: * handles-private.h: Reference the handle when it is locked, so that another thread can't blow it away while we're waiting for it to become signalled. * wait.c: * timed-thread.c: * threads.c: * sockets.c: * semaphores.c: * mutexes.c: * mono-mutex.c: * io.c: * handles.c: * handles-private.h: * events.c: * error.c: * daemon-messages.c: * critical-sections.c: * atomic.c: Added pthreads cleanup handlers and error asserts * shared.c: * handles.c: Fixed the gcc "variable might be used uninitialised" warnings. They can't happen, but gcc doesn't know that g_assert()s don't return. Fixed the declaration of _wapi_handle_process_kill() so that it expects the correct type for the pid. * threads.c: Removed the TLS_PTHREAD_MUTEX style locking that hasn't been used in ages and just made the code more complex. 2004-04-17 Zoltan Varga * processes.c: Include for SIGKILL and SIGILL + fix some warnings. Fixes #57168. 2004-04-16 Dick Porter * threads.c (Sleep): Using div(3) with a negative (when signed) numerator causes the quotient to be 0 and the remainder to be the numerator. This feeds a small negative value to nanosleep(3), which will return immediately and cause a busy wait. Fixes bug 56351. 2004-04-15 Dick Porter * io-private.h: * io.c: Rewrite FindFirstFile and FindNextFile using scandir(3) and fnmatch(3) instead of glob(3). glob() can't cope with being given filenames containing metachars. This fixes bug 40557. 2004-04-14 Bernie Solomon * security.c: #warning is a GCC-ism 2004-04-13 Sebastien Pouliot * security.c: Removed GetUserName as glib g_get_user_name does a better (portability) job. Added ImpersonateLoggedOnUser and RevertToSelf. 2004-04-06 Gonzalo Paniagua Javier * mono-mutex.h: move pthread_mutex_timedlock declaration to... * mono-mutex.c: ...here. It was causing a warning that prevented libgdiplus compilation. 2004-04-04 Miguel de Icaza * security.c (GetUserName): Make it work on MacOS X 2004-04-02 Gonzalo Paniagua Javier * security.c: use getpwuid_r if available. This one is thread-safe. 2004-04-02 Sebastien Pouliot * Makefile.am: Added security.c|h. * security.c: New file for security related functions. Added function GetUserName to fix #56144. * security.h: New. Header file for security.c * wapi.h: Added include for security.h 2004-03-25 Gonzalo Paniagua Javier * daemon-messages.h: added kill structs. * daemon.c: implemented process_process_kill. * handles-private.h: define process_process_kill. * handles.c: implemented _wapi_handle_process_kill. * processes.[ch]: implemented TerminateProcess. 2004-03-25 Bernie Solomon * daemon.c (rem_fd): On solaris you seem to get an error even after removing the input source so don't try and rem_fd it twice. 2004-03-25 Lluis Sanchez Gual * daemon.c: in process_post_mortem, If the child terminated due to the receipt of a signal, the exit status must be based on WTERMSIG, since WEXITSTATUS returns 0 in this case. 2004-03-22 Gonzalo Paniagua Javier * daemon.c: turned a warning into a DEBUG statement. Now we may hit it. 2004-03-19 Gonzalo Paniagua Javier * daemon.c: only call getdtablesize () once. * processes.c: wait 500 ms to check if execve failed and throw the same exception as MS on failure. Fixes bug #32809. 2004-03-17 Bernie Solomon * io.c (async_notifier): use "union sigval" rather than sigval_t as Solaris doesn't have sigval_t (which isn't in IEEE 1003.1 either). 2004-03-16 Gonzalo Paniagua Javier * io.c: added debug stuff and removed a few redundant lines in file_write. 2004-03-15 Gonzalo Paniagua Javier * io-private.h: added new fields for file structure. Declare _wapi_io_add_callback. * io.c: added _wapi_get_win32_error, support aio_read/write in file_read/write. Implemented _wapi_io_add_callback, which is where BindHandle ends up. * io.h: added new fields for WapiOverlapped and typedef for the callback. * processes.c: fixed off-by-one bug when handling environment variables passed in. * threads.[ch]: implemented BindIoCompletionCallback. * uglify.h: added typedef for LPOVERLAPPED_COMPLETION_ROUTINE. 2004-03-14 Zoltan Varga * socket-wrappers.h: Remove extra semicolon. 2004-03-03 Dave Camp * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main): Use a new main context. 2004-03-04 Gonzalo Paniagua Javier * io.c: (GetFileAttributes): set the error depending on errno instead of setting ERROR_FILE_NOT_FOUND always. See bug #55160. 2004-03-01 Gonzalo Paniagua Javier * io.c: (CopyFile): free the buffer on error. * sockets.c: (WSAIoctl): free the buffer on error. 2004-02-19 Gonzalo Paniagua Javier * error.c: fixed mapping for EPROTONOSUPPORT and ESOCKTNOSUPPORT. * sockets.[ch]: retry creating the socket for AF_INET, SOCK_RAW using IP protocol with IP over IP. Implemented WSAIoctl UNIX-style. 2004-01-27 Bernie Solomon * shared.c (_wapi_shm_file): add hostname to shared data file names to handle NFS mounted .wapi directories. Mon Jan 26 16:15:03 CET 2004 Paolo Molaro * sockets.h: remove obsolete soklen_t typedef. Fri Jan 23 21:07:02 CET 2004 Paolo Molaro * socket-wrappers.h, sockets.h, sockets.c, Makefile.am: move socket wrappers to its own non-installed header file. 2004-01-22 Gonzalo Paniagua Javier * io.c: (FindFirstFile): unlock the handle if FindNextFile fails. (FindNextFile): g_free a couple of pointers before retrying. * wait.c: (WaitForMultipleObjects): if only one handle provided, use WaitForSingleObject. 2003-12-22 Bernie Solomon * handles-private.h: (_wapi_handle_type) check for segment in range before using it 2003-12-22 Bernie Solomon * thread-private.h: _wapi_thread_ops is now const must match .c file. Mon Dec 22 18:29:03 CET 2003 Paolo Molaro * threads.c, timed-thread.c, timed-thread.h: use mach semaphores on Darwin (MacOSX) since the posix ones are mostly broken there (threads are not created suspended and they can start executing before they are fully initialized like in tests/thread-static.cs). Mon Dec 22 17:18:45 CET 2003 Paolo Molaro * atomic.h: ppc fixes. 2003-12-19 Bernie Solomon * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH in HDRSIZE 2003-12-15 Bernie Solomon * shared.c: (_wapi_shm_open) make scratch file not have to immediately regrow to avoid remaps (HPUX can't cope with these). (_wapi_shm_attach) use actual size of file to set scratch data_len for the creating process. * handles.c: (_wapi_handle_new_internal) make sure mutex & cond var are initialized even for non process shared ones. (_wapi_handle_unref) always call destroy routines on mutex & cond var 2003-12-15 Bernie Solomon * daemon.c: change channel data structure so input sources are removed from glib event loop properly. xsp works better on Solaris and fixes #51278 2003-12-12 Bernie Solomon * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION definition with file & line number for non-GCC compiles. 2003-12-08 Bernie Solomon * Makefile.am: make sure hppa_atomic.s is in distribution 2003-12-01 Dick Porter * wapi-private.h: * mutexes.c (CreateMutex): * mutex-private.h (struct _WapiHandle_mutex): * handles.c: Look up certain handle types by name, in a shared namespace. Currently only mutex handles have this implemented. Fixes bug 51089. * semaphores.c (CreateSemaphore): * events.c (CreateEvent): Fix signature 2003-11-24 Gonzalo Paniagua Javier * io.c: don't call g_free before testing errno as it may modify it. If the path exists, return an error if it's not a directory. Fixes bug #50753. 2003-11-20 Dick Porter * io.c: Missed a little-endian UTF16 conversion. Patch from Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065. 2003-10-29 Dick Porter * io.c (MoveFile): If the move crosses filesystems, try and fall back to copy and delete. Patch from Jörg Rosenkranz (JoergR@voelcker.com), fixes bug 50298. 2003-10-28 Dick Porter * io.c: Use the new encoding conversion to cope with non-utf8 locales in filenames. * processes.c: Ditto for process arguments. Tue Oct 21 12:01:14 CEST 2003 Paolo Molaro * atomic.h: some ppc inline asm fixes (incorrect use of labels, incorrect register constraints, incorrect clobber lists). 2003-10-13 Bernie Solomon * Makefile.am hppa_atomic.s: add HP 64bit implementation of atomic ops 2003-10-13 Zoltan Varga * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in a conditional for platforms that don't have it. 2003-10-09 Bernie Solomon * threads.c: (CreateThread) use stacksize argument if non-zero - change default for 64 bits to 4Mb 2003-09-29 Gonzalo Paniagua Javier * sockets.c: set last error when socket creation fails. This shed some light on bug #49015. 2003-09-28 Gonzalo Paniagua Javier * processes.c: fixed bug #48973: we only change \ by / for the argument to be used as command. When getting the program name from the args, don't let the space between them in the args. 2003-09-24 Bernie Solomon * atomic.h atomic.c: fix sparc so lock is global, increment does so and it compiles under Sun compiler. 2003-09-22 Bernie Solomon * handles.c: include directly as may not be nested in like Linux 2003-09-22 Gonzalo Paniagua Javier * io.c: (DeleteFile): call SetLastError on failure. Fix by richard.torkar@htu.se (Richard Torkar). Closes bug #48222. 2003-09-15 Lluis Sanchez Gual * daemon.c: In compare_process(), discard handles already signalled. 2003-09-02 Dick Porter * io.c: Work around glib brain-dead assumptions about utf8-encoded filenames. Fixes bug 30781. 2003-08-28 Dick Porter * critical-sections.c: Patch from Bernie Solomon to emit a warning if locking a critical section fails. 2003-07-23 Dick Porter * shared.c: * daemon.c (maybe_exit): Avoid the race condition when the daemon is closing but another client comes along when the shared data is still visible. Should fix bugs 33671 and 35213. 2003-07-23 Dick Porter * handles.c: Initialise handle mutex and cond. Fix by Bernie Solomon 2003-07-15 Dick Porter * timed-thread.c (timed_thread_start_routine): Fix virtual memory leak when threads quit. Fixes bug 44067. Wed Jun 18 19:08:40 CEST 2003 Paolo Molaro * io.c: never add write permission for group or others in SetFileAttributes (). 2003-06-17 Dick Porter * io.c (SetFileAttributes): Implement the ReadOnly attribute, and ignore the unsupported ones ("fixes" bug 44977). 2003-06-17 Lluis Sanchez Gual * misc.c: fix bug in _wapi_calc_timeout. It gave wrong values for high ms values (there was an overflow). 2003-06-17 Zoltan Varga * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3. 2003-06-11 Dick Porter * shared.c: Fix shared directory creation. Patch from Pablo Baena 2003-06-10 Dick Porter * atomic.c: Delete the useless compile warning 2003-06-09 Dick Porter * daemon.c: Lookup env as a string array. Fixes bug 44289. Also make setting the process handle value in the environment actually work. * processes.c: Pretty up the process name, if it happens to be "mono" such as when another mono process forks "mono foo.exe" 2003-06-05 Dick Porter * processes.c (process_set_current): Don't do an expensive handle search at application startup, check the environment to see if the process handle has already been created. * io.c: Don't do an expensive handle search when creating stdin, stdout and stderr handles, just create them all the first time one is requested. * wapi-private.h: * shared.c: * shared.h: * handles.c: * handles-private.h: * daemon-messages.h: * daemon-private.h: * daemon.c: Support for "unlimited" number of handles and scratch data. Speed up application startup by passing process handle in the environment, rather than let the app scan all handles (which gets really slow when there are more than a few thousand to check.) Initialise some structs passed to syscalls, noticed by valgrind. 2003-05-20 Dick Porter * io.c (FindFirstFile): Include . files in the glob. Fixes bug 43229. 2003-05-19 Dick Porter * threads.c: Set the new thread's stack size to 2M. Fix needed for BSD, reported by Martin Dvorak 2003-05-16 Dick Porter * io.h: * io.c: Implement GetTempPath() 2003-05-16 Dick Porter * processes.c (CreateProcess): Set some error codes 2003-05-12 Dick Porter * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec. Patch from Martin Dvorak . 2003-05-10 Dick Porter * io.c (CopyFile): Copy file mode as well as file data. Based on suggestion by Giuseppe Greco , bug 42706. 2003-05-06 Gonzalo Paniagua Javier * handles.c: don't call GC_gcollect when creating new handles. 2003-05-05 Gonzalo Paniagua Javier * handles.c: added some debugging code. Call GC_gcollect before creating a new handle. It makes Lupus' test run smoother and faster (from 62 to 83 request per second). Notice that calling GC_finalizer_notifier if needed (GC_should_invoke_finalizer ()) does not improve nor degrade the performance, so i don't do it. 2003-05-02 Dick Porter * sockets.c: Rearrange closesocket() and socket_close_private(), and remember to unref the handle, so we don't leak socket handles. Fix from Pelle Johnsen 2003-04-11 Dick Porter * atomic.h: ARM atomic operations by Malte Hildingson Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro * atomic.h: fix macosx build by "Urs C. Muff" . 2003-04-03 Martin Baulig The following change is conditional to `WITH_INCLUDED_LIBGC' which is not yet enabled by default. * threads.c (SuspendThread, ResumeThread): Fully implemented this. (gc_init): New static function; install a signal handler for SIGPWR which is used to suspend threads. [FIXME: it SIGPWR doesn't exist on all Unix systems, we need to find another signal]. (mono_wapi_push_thread_stack): New public function. Tells the garbage collector about the current stack pointer of a suspended thread. 2003-04-03 Martin Baulig * timed-thread.h (TimedThread): Added `suspended_sem', `suspend_count' and `stack_ptr'. 2003-03-28 Dick Porter * atomic.h: PPC support gratiously donated to the public domain by John Duncan 2003-03-20 Dick Porter * sockets.c (_wapi_connect): If connect() fails with EACCES, try setting SO_BROADCAST and connecting again. Fixes bug 39178. 2003-03-13 Gonzalo Paniagua Javier * processes.c: included Jerome Laban's patch and call SetLastError when the executable is not found. 2003-03-03 Dick Porter * io.c (CreateFile): Try opening directories readonly, so that timestamps can be adjusted. Patch by Elan Feingold . 2003-02-25 Dick Porter * shared.c (_wapi_shm_attach): Return a failure code on system call errors, rather than exiting. 2003-02-21 Dick Porter * processes.c (GetCurrentProcessId): Use the current process handle to return the process ID, as getpid() is unreliable (linuxthreads gives each thread a different pid). Fixes bug 37550. 2003-02-21 Dick Porter * io.c (FindNextFile): Skip over dangling symlinks. Fixes bug 34076. 2003-02-11 Dick Porter * timefuncs.h: * timefuncs.c: Added GetTickCount() 2003-02-06 Gonzalo Paniagua Javier * error.c: added WSA_EHOSTUNREACH mapping. 2003-01-26 Miguel de Icaza * io.c (SetFileAttributes): This routine is not currently implemented for the general case, but I added a special case to set the executable bit on Linux. Wed Jan 15 15:55:40 CET 2003 Paolo Molaro * sockets.h, daemon.c, io.c: compilation fixes on MacOSX. 2003-01-08 Dick Porter * sockets.c: Fixed setting blocking mode to true (fixes bug 36388) 2002-12-11 Juli Mallett * daemon.c, handles-private.h, handles.c, wapi-private.h: Check for an implementation which says it supports _POSIX_THREAD_PROCESS_SHARED, rather than just one that defines the symbol. Defined but with a value of -1 still means that it is unsupported. 2002-12-08 Martin Baulig * handles.c (_wapi_handle_new): Create new non-shared handles with an initial refcount of 1, not 0. 2002-11-22 Dietmar Maurer * threads.c (TlsGetValue): removed unnecessary mutex 2002-11-20 Dick Porter * timed-thread.c (_wapi_timed_thread_attach): Attached threads need to store their data structure too. * threads.c: Make sure the threading data is initialised wherever it is needed 2002-11-15 Dick Porter * timed-thread.c: Removed unneeded parameters in _wapi_timed_thread_attach(). * threads.c: Renamed AttachThread() to make it not look like external API. Removed unneeded parameters. 2002-11-11 Gonzalo Paniagua Javier * error.[ch]: added errno_to_WSA (). It displays a warning and return WSASYSCALLFAILURE if there is no error mapping for the given errno, * sockets.c: use errno_to_WSA and fixed display of warning for h_errno. 2002-10-31 Dick Porter * io.h: * io.c: Define and use INVALID_FILE_ATTRIBUTES 2002-10-07 Dick Porter * timefuncs.c: * daemon.c: Use a more accurate time source for process start and end times. 2002-10-03 Dick Porter * daemon.c: * handles.c: * threads.c: Fixes for freebsd. Make sure that mutex and condition creation and deletion happen in the process that owns them, when POSIX shared thread objects aren't supported. This breaks on freebsd, as pthread_t is a pointer to data. 2002-10-02 Dick Porter * shared.c: Use mmap() instead of sysv shm for the shared data. * wapi-private.h (_WAPI_HANDLE_VERSION): Reset back to 0, for the new system * daemon-private.h: * daemon.c: mmap()ed regions survive fork, so just pass the pointer to _wapi_daemon_main instead of mapping it again. 2002-10-01 Dick Porter * timed-thread.c: Kludge for CREATE_SUSPENDED thread creation. Unfortunately libgc uses the same thread suspend technique that I want to, and the two don't mix: libgc will deadlock when it tries to stop the world if a thread has already been suspended by someone else. Just do the simple suspended create rather than the general purpose thread suspension for now. * threads.c: Pass create flags to the timed_thread create call, to implement suspended thread creation. ResumeThread() partially implemented, to cope with the case where a newly created but suspended thread is launched. 2002-09-30 Dick Porter * sockets.c (ioctlsocket): Set non-blocking mode in a better way, with fcntl. 2002-09-27 Dick Porter * semaphores.c: Only include semaphore.h if it's present. Patch for BSD from jmmv@hispabsd.org (Julio Merino). 2002-09-27 Dick Porter * processes.c: Pass environment and working directory to the daemon when forking. Don't let argv[0] be duplicated when looking for the program name. Implement EnumProcessModules (simple version for now, lsof-style later if needed), GetModuleBaseName, {Get,Set}ProcessWorkingSetSize (just faked, because the vm hints aren't available on Linux). * process-private.h: Store the process name, and the working set min and max * handles.c: * handles-private.h: New functions to store and retrieve an array of strings in the scratch space * daemon.c: Don't miss deleting some handles when a client exits (we used to rely on the client doing the final cleanup, but obviously if the client is no longer there the daemon has to do it). Process forking now sets the environment and the working directory. * io.c: Don't confuse fd 0 with an unassigned handle struct * atomic.h: Add a google cache alternative to the msdn URL 2002-09-25 Gonzalo Paniagua Javier * sockets.c: (_wapi_recvfrom): added ECONNRESET to the switch. 2002-09-24 Mark Crichton * atomic.h: Yea. On linux, sparc isn't sparc, it's __sparc__. Added to ifdef. 2002-09-19 Mark Crichton * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that dont have Linux's abstract filesystem for sockets. 2002-09-19 Mark Crichton * atomic.h: Added SPARC atomic asm code. * daemon.c, handles-private.h, handles.c, wapi-private.h: undefined _POSIX_THREAD_PROCESS_SHARED. This actually exists on Solaris 9, however, the code paths don't seem to work. More testing on the shared case is *really* needed. 2002-09-03 Dick Porter * threads.h: * threads.c: Removed PosixKillThread(), because it's not in the w32 api 2002-08-20 Dick Porter * handles.c (_wapi_handle_scratch_store): Made stored byte lengths multiples of 4 bytes, to keep header structures aligned. Needed for sparc, at least. (Patch from crichton@gimp.org) * handles.c: Removed 'disable_shm' variable (we've defaulted to building with shm enabled for months now) 2002-08-19 Dick Porter * daemon.c: Rewrote the poll() loop to use GIOChannels instead, for legacy NeXT-based systems. 2002-08-12 Dick Porter * atomic.h: Rename some parameters to avoid c++ keywords (Patch from Joseph Wenninger ) 2002-08-05 Dietmar Maurer * threads.c: use fast spinlocks by default 2002-08-02 Dick Porter * io.c (GetStdHandle): Add a handle reference when returning a duplicate console handle. This fixes the unref_handle errors in NUnit. 2002-08-01 Dietmar Maurer * threads.c (TLS_PTHREAD_MUTEX): define this because else some tests does not work 2002-08-01 Dick Porter * threads.c: Use atomic spinlocks in TLS functions * mono-spinlock.h: * Makefile.am: Added mono-spinlock.h 2002-07-21 Jeffrey Stedfast * daemon-messages.c: #include and - these are needed for sendmsg() and also for struct msghdr (at least on Solaris). Solaris still won't build because struct msghdr doesn't have msg_flags, msg_control, or msg_controllen members. (CMSG_SPACE): Define for systems that don't have it. (CMSG_LEN): Same. 2002-07-20 Dick Porter * wapi-private.h: * io-private.h: * io.h: * io.c: * handles.c: Implemented pipe handles * handles.c: * daemon.c: Fixed bug in handle closing. * shared.c: * daemon.c: Forked processes now close all open file descriptors. Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro * sockets.h, io-layer.h, critical-sections.h: don't include config.h in header files. 2002-07-19 Martin Baulig * threads.c (ExitThread): Call exit() if no threads has been created yet. 2002-07-17 Dick Porter * daemon-messages.c: Freebsd fixes from Andreas Kohn 2002-07-15 Dick Porter * io.c: Removed bogus console_flush() method, that was just cut and pasted from file_flush when I separated the two handle types. 2002-07-12 Dick Porter * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl flags. Fixes bug 27633. 2002-07-12 Dick Porter * wapi-private.h: * handles.c: * daemon.c: Use size of sockaddr_un.sun_path from config.h 2002-07-12 Dick Porter * processes.c (CreateProcess): Send stdin, stdout and stderr handles if the startup info doesnt specify new ones * io.c (GetStdHandle): Return the same handle when the same standard handle is requested * handles.c: Pass file descriptors when forking * daemon.c: Use supplied file descriptors when forking a new process * daemon-messages.h: * daemon-messages.c: Pass stdin, stdout and stderr file descriptors to the daemon (used when forking) 2002-07-11 Miguel de Icaza * daemon.c (_wapi_daemon_main): Use sizeof (main_socket_address.sun_path) instead of hardcoded 108 value. * handles.c (shared_init): Use sizeof (shared_socket_address.sun_path) instead of hardcoded 108 value. 2002-07-10 Dennis Haney * shared.c: * handles.c: * daemon.c: Lots of documentation, some added error checking, and code readability improvements. * daemon-messages.h: Add the Error request type to improve error checking. * daemon-messages.c: Do a bit more error checking on send() and recv(), and log errors with a higher severity level. 2002-07-04 Dick Porter * daemon.c (process_process_fork): Fix argument handling, due to buggy understanding of g_strsplit() behaviour. 2002-07-03 Dick Porter * threads.h: * threads.c: Implement OpenThread(). Define access-control values for thread handles. * wapi.h: * processes.h: * access.h: * Makefile.am: Added access.h, to hold shared access-control definitions 2002-07-02 Dick Porter * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version 2002-07-02 Dick Porter * handles.c (shared_init): Make a second attempt to contact the daemon if the shared memory attach succeeds, but the connect() fails. (This copes with the daemon crashing without cleaning up the shared memory.) * Makefile.am: * daemon-private.h: * daemon.c: * shared.c (_wapi_shm_attach): Don't exec() anything when we fork the daemon, it's now built into the library. 2002-06-25 Dick Porter * handles.c: * handles-private.h: * daemon-messages.h: * daemon.c: Process forking and handle data management * processes.h: * process-private.h: * processes.c: Process forking and other support functions 2002-06-25 Dick Porter * versioninfo.h: PE resource decoding * unicode.c (_wapi_unicode_to_utf8): g_utf16_to_utf8 doesnt need to be told the string length * io.c: Removed the ACTUALLY_DO_UNICODE option. Fixed some leaks. Moved _wapi_time_t_to_filetime and the WapiFileTime typedef to timefuncs.c 2002-06-12 Dick Porter * daemon.c: * daemon-messages.c: Handle SIGPIPE in a non-stupid way in the daemon, if MSG_NOSIGNAL isn't available. Thanks to Jaroslaw Kowalski for pointing out the bogosity. 2002-06-10 Jaroslaw Kowalski * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised when writing to a closed socket. 2002-06-08 Jeffrey Stedfast * mono-mutex.c (mono_once): New convenience function for my previous fix. * handles.c: * error.c: * critical-sections.c: * threads.c: * sockets.c: * semaphores.c: * processes.c: * mutexes.c: * io.c: * events.c: * atomic.c: Use mono_once() rather than pthread_once(). 2002-06-06 Jeffrey Stedfast * handles.c (_wapi_handle_new): pthread_once() is not atomic, so if multiple threads all try to call _wapi_handle_new() before the shared data has been initialized, it is possible that we could get into a condition where shared_init() is being executed and later threads will pass by pthread_once() due to the fact that it has already been called and so therefor will attempt to use the shared data before it has been completely initialized. If we instead use a standard mutex locking mechanism around shared_init(), we can avoid the situation entirely. By wrapping the mutex locking in a check to see if we've already initialized the data, we can even avoid wasting resources by having to lock/unlock the mutex in any later calls (the only time we'd have to worry about locking/unlocking is the initial race to call shared_init() at startup). Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk). Fri May 31 16:21:54 CEST 2002 Paolo Molaro * daemon.c, handles.c: rename "sun" local var since it's apparently a #define on Solaris. Fri May 31 15:40:14 CEST 2002 Paolo Molaro * daemon-messages.c: work-around MSG_NOSIGNAL missing on some platforms. 2002-05-15 Dick Porter * wait.c: Fix a deadlock in WaitForMultipleObjects 2002-05-14 Dick Porter * io.c: Fix a cut&paste error, found by Jaroslaw Kowalski 2002-05-10 Dan Lewis * io.c: Nasty typo. 2002-05-09 Dick Porter * threads.c: * semaphores.c: * processes.c: * mutexes.c: * handles-private.h: * events.c: * Makefile.am: Remove now-unused file wait-private.h 2002-05-08 Dick Porter * shared.c: Better error messages, and report when daemon connection fails rather than blocking forever. Do some more shared memory sanity checking. * handles.c: Better error messages when connecting to shared memory and the handle daemon. Fall back to non-shared handles if an error occurs. Set the default back to 'shared handles'. Fix a crashing bug in scratch space allocation that mangled the block headers. 2002-05-07 Miguel de Icaza * handles.c (shared_init): Disable SHM for now, people have too many problems with this, and the diagnostics are not helping. 2002-05-06 Dan Lewis * io.c: CreateFile sets win32 last error. 2002-05-05 Dick Porter * wapi-private.h: * handles-private.h: * io.c: * io-private.h: * mutexes.c: * mutex-private.h: * processes.c: * process-private.h: * semaphores.c: * semaphore-private.h: * sockets.c: * socket-private.h: * events.c: * event-private.h: Simplify the WapiHandleOps struct: take out all the file-specific entries, leaving just the items that operate on handles themselves. Split the close operation into shared and private parts: shared close is called by the daemon. * handles.c: As above, but also pass handle allocation, ref and unref operations to the daemon. Populate the handle_ops array at compile time, because the daemon needs to call ops on handles too. Don't bother to track open handle counts any more, the daemon does that. * threads.c: * thread-private.h: As above, but also make the thread data handle-private. * shared.c: Fork a handle daemon if the calling process created the shared memory segment. * daemon.c: * daemon-messages.c: * daemon-messages.h: * Makefile.am: Build a daemon to manage handle allocation and destruction without needing to lock the shared memory 2002-04-30 Jeffrey Stedfast * atomic.c: Changed to use a normal mutex rather than a spinlock since a lot of platforms seem to not have them :\ 2002-04-30 Dick Porter * Completely rewrote the handle waiting code: removed the helper thread and its attendant complexity. All handle waiting is now abstracted into the WaitForSingleObject() and WaitForMultipleObjects() functions. * Implemented inter-process sharing of handles using sysv shared memory. This makes handles even more opaque, with a handle now just an index into an array. 2002-04-25 Dan Lewis * io.c: unitialized pointer in GetCurrentDirectory. Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro * threads.c: destroy the mutex at thread destruction (if/when thread destruction code will be actually called). When protecting a tls data pointer from the gc, use also the thread id in the key. Wed Apr 17 18:36:27 CEST 2002 Paolo Molaro * timed-thread.c: avoid race condition when setting the thread to detached. 2002-04-16 Gonzalo Paniagua Javier * jit.h: to more #include lines to avoid breaking compilation under windows when upgrading mingw and w32api to version 1.3 (thanks Dick!). 2002-04-16 Dick Porter * atomic.h: Explanatory comment about lack of 80386 support 2002-04-15 Dick Porter * atomic.h: use xaddl for InterlockedIncrement() and InterlockedDecrement(). Use cmpxchgl in a loop for InterlockedExchange() and InterlockedExchangePointer(). Mon Apr 15 13:31:22 CEST 2002 Paolo Molaro * unicode.c: fix unicode_len() to not access uninitialized memory (and updated to conform to mono code style). Fri Mar 29 17:15:11 CET 2002 Paolo Molaro * io.c: EEXISTS is ignored for directory creation. * mono-mutex.h: remove silly "pragma }" that emacs users insert because they use a broken editor:-) 2002-03-28 Dick Porter * sockets.h: * sockets.c: * io.c: * handles.h: * handles.c: Warning cleanups 2002-03-27 Dan Lewis * unicode.h, unicode.c: changed to gunichar2 * io.h, io.c: changed strings to gunichar2*, added SetFileAttributes(), GetCurrentDirectory(), SetCurrentDirectory(), some fixes to FindFirstFile() and friends. 2002-03-26 Dick Porter * types.h: Implement the large integer struct * timefuncs.h: * timefuncs.c: Dummy functions that don't yet implement QueryPerformanceCounter() and QueryPerformanceFrequency() * threads.h: * threads.c: Implement SleepEx() * system.h: * system.c: Beginnings of GetSystemInfo() * mono-mutex.c (pthread_mutex_timedlock): Fix a ms/ns conversion thinko * context.h: * context.c: Dummy function that doesnt yet implement GetThreadContext() * atomic.h: * atomic.c: Interlocked functions Mon Mar 25 13:01:40 CET 2002 Paolo Molaro * threads.c: use a gc-safe hash table to store tls pointers. 2002-03-22 Dick Porter * threads.c: Fix a race condition where a thread can start and exit before the handle has been properly initialised (no reason why the handle couldn't be initialised beforehand, so do so) Fix a ms to ns conversion magnitude thinko. 2002-03-21 Dick Porter * semaphores.c: Fix a problem when waiting for one or more semaphores, and another semaphore is Released (all waiting semaphores assumed they were signalled) 2002-03-29 Dan Lewis * io.h, io.c, uglify.h: added MoveFile, CopyFile, CreateDirectory, RemoveDirectory, GetFileAttributes, GetFileAttributesEx 2002-03-19 Dietmar Maurer * threads.c (Sleep): bug fix: 1ms == 1000000ns 2002-03-19 Dan Lewis * io.h, io.c, events.c, mutexes.c, semaphores.c, sockets.c, threads.c, io.c: added flush method to handles. * io.c: FlushFileBuffers() and FindFirstFile() functions. Thu Mar 7 17:21:52 CET 2002 Paolo Molaro * threads.c, timed-thread.c, wait.c: Boehm-GC anable. 2002-02-20 Dick Porter * io-layer.h: Always build without cygwin support on windows Mon Feb 18 15:50:59 CET 2002 Paolo Molaro * sockets.c: #undef DEBUG. 2002-02-14 Jeffrey Stedfast * io-layer.h: conditionally include sys/filio.h and sys/sockio.h for FIONBIO, FIONREAD, and SIOCATMARK. 2002-02-14 Jeffrey Stedfast * sockets.c: conditionally include sys/filio.h and sys/sockio.h for FIONBIO, FIONREAD, and SIOCATMARK. 2002-02-13 Dick Porter * sockets.c: Implement shutdown and select 2002-02-13 Jeffrey Stedfast * mono-mutex.[c,h]: New source files that thinly wrap all pthread functions that take pthread_mutex_t and/or pthread_mutexattr_t arguments for the sake of portability.
