2004-05-27  Dick Porter  <dick@ximian.com>

        * io.h:
        * io.c: Implemented LockFile() and UnlockFile()

2004-05-21  Dick Porter  <dick@ximian.com>

        * 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  <lluis@ximian.com>

        * 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  <dick@ximian.com>

        * io.c (CopyFile): Speed up.  Fixes bug 57859.

2004-05-13  Dick Porter  <dick@ximian.com>
        * 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  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * io.c:
        (SetFileAttributes): don't the the exec bit if the corresponding read
        bit is not set.

2004-05-10  Zoltan Varga  <vargaz@freemail.hu>

        * io.c (FindFirstFile): Fix invalid free.

2004-05-09  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * io.c (SetFileAttributes): Don't have failed chmod()s cause a
        "file not found" error.  Fixes bug 54032.
        
2004-05-07  Dick Porter  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * io.c: fixed for FindFirstFile for empty directories. Closes
        bug #58147.

2004-05-06  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * processes.c: set the start time for the current process. Fixes bug
        #58109.

2004-05-06  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * io-private.h: 'namelist' is now a gchar ** in _WapiHandlePrivate_find.
        * io.c: implemented scandir using glib functions.

2004-05-04  Dick Porter  <dick@ximian.com>

        * 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  <miguel@ximian.com>

        * 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  <vargaz@freemail.hu>

        * io.c: Add scandir implementation for platforms which do not have
        it, like solaris.

2004-04-29  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * io.[ch]: implemented GetLogicalDriveStrings.

2004-04-29  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <bernard@ugsolutions.com>

        * atomic.c: (InterlockedExchange) fix typo for
        mutex name

2004-04-28  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * io.c:
        * sockets.c: added check for sys/aio.h.

2004-04-28  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <mass@akuma.org>

        * 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 <mass@akuma.org>

        * io.c:
        * timefuncs.c: declare 64-bit constants as long long types (i.e.
        10ULL)

2004-04-24  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <miguel@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <vargaz@freemail.hu>

        * processes.c: Include <signal.h> for SIGKILL and SIGILL + fix some
        warnings. Fixes #57168.

2004-04-16  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <bernard@ugsolutions.com>

        * security.c: #warning is a GCC-ism

2004-04-13  Sebastien Pouliot  <sebastien@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <miguel@ximian.com>

        * security.c (GetUserName): Make it work on MacOS X

2004-04-02  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * security.c: use getpwuid_r if available. This one is thread-safe.

2004-04-02  Sebastien Pouliot  <sebastien@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <bernard@ugsolutions.com>

        * 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  <lluis@ximian.com>

        * 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 <gonzalo@ximian.com>

        * daemon.c: turned a warning into a DEBUG statement. Now we may hit it.

2004-03-19  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <bernard@ugsolutions.com>

        * 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 <gonzalo@ximian.com>

        * io.c: added debug stuff and removed a few redundant lines in
        file_write.

2004-03-15  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <vargaz@freemail.hu>

        * socket-wrappers.h: Remove extra semicolon.

2004-03-03  Dave Camp  <dave@ximian.com>

        * daemon.c: (add_fd), (fd_activity), (_wapi_daemon_main):
        Use a new main context.

2004-03-04  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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 <gonzalo@ximian.com>

        * io.c:
        (CopyFile): free the buffer on error.
        * sockets.c:
        (WSAIoctl): free the buffer on error.

2004-02-19  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <bernard@ugsolutions.com>

        * 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 <lupus@ximian.com>

        * sockets.h: remove obsolete soklen_t typedef.

Fri Jan 23 21:07:02 CET 2004 Paolo Molaro <lupus@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <bernard@ugsolutions.com>

        * handles-private.h: (_wapi_handle_type) check
        for segment in range before using it

2003-12-22  Bernie Solomon  <bernard@ugsolutions.com>

        * thread-private.h: _wapi_thread_ops is now const
        must match .c file.

Mon Dec 22 18:29:03 CET 2003 Paolo Molaro <lupus@ximian.com>

        * 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 <lupus@ximian.com>

        * atomic.h: ppc fixes.

2003-12-19  Bernie Solomon  <bernard@ugsolutions.com>

        * handles.c: remove my bad use of MONO_ZERO_ARRAY_LENGTH
        in HDRSIZE 

2003-12-15  Bernie Solomon  <bernard@ugsolutions.com>

        * 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  <bernard@ugsolutions.com>

        * 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  <bernard@ugsolutions.com>

        * wapi-private.h: Replace G_GNUC_PRETTY_FUNCTION
        definition with file & line number for non-GCC
        compiles.

2003-12-08  Bernie Solomon  <bernard@ugsolutions.com>

        * Makefile.am: make sure hppa_atomic.s is in distribution

2003-12-01  Dick Porter  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * io.c: Missed a little-endian UTF16 conversion.  Patch from
        Jeroen Zwartepoorte (Jeroen@xs4all.nl), fixes bug 51065.

2003-10-29  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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 <lupus@ximian.com>

        * atomic.h: some ppc inline asm fixes (incorrect use of labels, 
        incorrect register constraints, incorrect clobber lists).

2003-10-13  Bernie Solomon  <bernard@ugsolutions.com>

        * Makefile.am hppa_atomic.s: add HP 64bit
        implementation of atomic ops

2003-10-13  Zoltan Varga  <vargaz@freemail.hu>

        * threads.c (CreateThread): Wrap pthread_attr_setstacksize call in
        a conditional for platforms that don't have it.

2003-10-09  Bernie Solomon  <bernard@ugsolutions.com>

        * threads.c: (CreateThread) use stacksize argument
        if non-zero - change default for 64 bits to 4Mb

2003-09-29  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * sockets.c: set last error when socket creation fails. This shed some
        light on bug #49015.

2003-09-28  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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 <bernard@ugsolutions.com>

        * atomic.h atomic.c: fix sparc so lock is
        global, increment does so and it compiles under Sun compiler.

2003-09-22  Bernie Solomon <bernard@ugsolutions.com>

        * handles.c: include <string.h> directly as may
        not be nested in <sys/un.h> like Linux

2003-09-22  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * io.c:
        (DeleteFile): call SetLastError on failure. Fix by
        richard.torkar@htu.se (Richard Torkar). Closes bug #48222.

2003-09-15  Lluis Sanchez Gual  <lluis@ximian.com>

        * daemon.c: In compare_process(), discard handles already signalled.

2003-09-02  Dick Porter  <dick@ximian.com>

        * io.c: Work around glib brain-dead assumptions about utf8-encoded
        filenames.  Fixes bug 30781.

2003-08-28  Dick Porter  <dick@ximian.com>

        * critical-sections.c:  Patch from Bernie Solomon
        <bernard@ugsolutions.com> to emit a warning if locking a critical
        section fails.

2003-07-23  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * handles.c:  Initialise handle mutex and cond.  Fix by
        Bernie Solomon <bernard@ugsolutions.com>

2003-07-15  Dick Porter  <dick@ximian.com>

        * 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 <lupus@ximian.com>

        * io.c: never add write permission for group or others in
        SetFileAttributes ().

2003-06-17  Dick Porter  <dick@ximian.com>

        * io.c (SetFileAttributes): Implement the ReadOnly attribute, and
        ignore the unsupported ones ("fixes" bug 44977).

2003-06-17  Lluis Sanchez Gual  <lluis@ximian.com>

        * 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  <vargaz@freemail.hu>

        * system.h (struct _WapiSystemInfo ): Fix warnings when using gcc-3.3.

2003-06-11  Dick Porter  <dick@ximian.com>

        * shared.c: Fix shared directory creation.  Patch from
        Pablo Baena <pbaena@uol.com.ar>

2003-06-10  Dick Porter  <dick@ximian.com>

        * atomic.c: Delete the useless compile warning

2003-06-09  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * io.c (FindFirstFile): Include . files in the glob.  Fixes bug
        43229.

2003-05-19  Dick Porter  <dick@ximian.com>

        * threads.c: Set the new thread's stack size to 2M.  Fix needed
        for BSD, reported by Martin Dvorak <md@9ll.cz>

2003-05-16  Dick Porter  <dick@ximian.com>

        * io.h:
        * io.c: Implement GetTempPath()

2003-05-16  Dick Porter  <dick@ximian.com>

        * processes.c (CreateProcess): Set some error codes

2003-05-12  Dick Porter  <dick@ximian.com>

        * misc.c (_wapi_calc_timeout): Cope with overflowing tv_nsec.
        Patch from Martin Dvorak <mdvorak@ninell.cz>.

2003-05-10  Dick Porter  <dick@ximian.com>

        * io.c (CopyFile): Copy file mode as well as file data.  Based on
        suggestion by Giuseppe Greco <giuseppe.greco@agamura.com>, bug
        42706.

2003-05-06  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * handles.c: don't call GC_gcollect when creating new handles.

2003-05-05  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * 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 <pelle.johnsen@mail.dk>

2003-04-11  Dick Porter  <dick@ximian.com>

        * atomic.h: ARM atomic operations by Malte Hildingson
        <tds00mahi@tellus.thn.htu.se>

Tue Apr 8 11:37:29 CEST 2003 Paolo Molaro <lupus@ximian.com>

        * atomic.h: fix macosx build by "Urs C. Muff" <umuff@quark.com>.

2003-04-03  Martin Baulig  <martin@ximian.com>

        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  <martin@ximian.com>

        * timed-thread.h (TimedThread): Added `suspended_sem',
        `suspend_count' and `stack_ptr'.

2003-03-28  Dick Porter  <dick@ximian.com>

        * atomic.h: PPC support gratiously donated to the public domain
        by John Duncan <jddst19@mac.com>

2003-03-20  Dick Porter  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * processes.c: included Jerome Laban's patch and call SetLastError when
        the executable is not found.

2003-03-03  Dick Porter  <dick@ximian.com>

        * io.c (CreateFile): Try opening directories readonly, so that
        timestamps can be adjusted.  Patch by Elan Feingold
        <efeingold@mn.rr.com>.

2003-02-25  Dick Porter  <dick@ximian.com>

        * shared.c (_wapi_shm_attach): Return a failure code on system
        call errors, rather than exiting.

2003-02-21  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * io.c (FindNextFile): Skip over dangling symlinks.  Fixes bug
        34076.

2003-02-11  Dick Porter  <dick@ximian.com>

        * timefuncs.h: 
        * timefuncs.c: Added GetTickCount()

2003-02-06  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * error.c: added WSA_EHOSTUNREACH mapping.

2003-01-26  Miguel de Icaza  <miguel@ximian.com>

        * 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 <lupus@ximian.com>

        * sockets.h, daemon.c, io.c: compilation fixes on MacOSX.

2003-01-08  Dick Porter  <dick@ximian.com>

        * sockets.c: Fixed setting blocking mode to true (fixes bug 36388)

2002-12-11  Juli Mallett  <jmallett@FreeBSD.org>

        * 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  <martin@ximian.com>

        * handles.c (_wapi_handle_new): Create new non-shared handles with
        an initial refcount of 1, not 0.

2002-11-22  Dietmar Maurer  <dietmar@ximian.com>

        * threads.c (TlsGetValue): removed unnecessary mutex

2002-11-20  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * io.h: 
        * io.c: Define and use INVALID_FILE_ATTRIBUTES

2002-10-07  Dick Porter  <dick@ximian.com>

        * timefuncs.c:
        * daemon.c: Use a more accurate time source for process start and
        end times.

2002-10-03  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * sockets.c (ioctlsocket): Set non-blocking mode in a better way,
        with fcntl.

2002-09-27  Dick Porter  <dick@ximian.com>

        * semaphores.c: Only include semaphore.h if it's present. Patch
        for BSD from jmmv@hispabsd.org (Julio Merino).

2002-09-27  Dick Porter  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * sockets.c:
        (_wapi_recvfrom): added ECONNRESET to the switch.

2002-09-24  Mark Crichton  <crichton@gimp.org>

        * atomic.h: Yea.  On linux, sparc isn't sparc, it's __sparc__.
        Added to ifdef.

2002-09-19  Mark Crichton  <crichton@gimp.org>

        * daemon.c, shared.c: Added NEED_LINK_UNLINK for systems that
        dont have Linux's abstract filesystem for sockets.

2002-09-19  Mark Crichton  <crichton@gimp.org>

        * 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  <dick@ximian.com>

        * threads.h: 
        * threads.c: Removed PosixKillThread(), because it's not in the
        w32 api

2002-08-20  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * daemon.c: Rewrote the poll() loop to use GIOChannels instead,
        for legacy NeXT-based systems.

2002-08-12  Dick Porter  <dick@ximian.com>

        * atomic.h: Rename some parameters to avoid c++ keywords (Patch
        from Joseph Wenninger <kde@jowenn.at>)

2002-08-05  Dietmar Maurer  <dietmar@ximian.com>

        * threads.c: use fast spinlocks by default

2002-08-02  Dick Porter  <dick@ximian.com>

        * 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  <dietmar@ximian.com>

        * threads.c (TLS_PTHREAD_MUTEX): define this because else some
        tests does not work

2002-08-01  Dick Porter  <dick@ximian.com>

        * threads.c: Use atomic spinlocks in TLS functions

        * mono-spinlock.h:
        * Makefile.am: Added mono-spinlock.h

2002-07-21  Jeffrey Stedfast  <fejj@ximian.com>

        * daemon-messages.c: #include <sys/types.h> and <sys/sockets.h> -
        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  <dick@ximian.com>

        * wapi-private.h:
        * io-private.h:
        * io.h:

Fri Jul 19 19:05:19 CEST 2002 Paolo Molaro <lupus@ximian.com>

        * sockets.h, io-layer.h, critical-sections.h: don't include config.h
        in header files.

2002-07-19  Martin Baulig  <martin@gnome.org>

        * threads.c (ExitThread): Call exit() if no threads has been
        created yet.

2002-07-17  Dick Porter  <dick@ximian.com>

        * daemon-messages.c: Freebsd fixes from Andreas Kohn
        <andreas.kohn@gmx.net>

2002-07-15  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * io.c (convert_from_flags): Fixed misunderstanding wrt fcntl
        flags.  Fixes bug 27633.

2002-07-12  Dick Porter  <dick@ximian.com>

        * wapi-private.h:
        * handles.c:
        * daemon.c: Use size of sockaddr_un.sun_path from config.h

2002-07-12  Dick Porter  <dick@ximian.com>

        * 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  <miguel@ximian.com>

        * 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  <davh@davh.dk>

        * 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  <dick@ximian.com>

        * daemon.c (process_process_fork): Fix argument handling, due to
        buggy understanding of g_strsplit() behaviour.

2002-07-03  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * wapi-private.h (_WAPI_HANDLE_VERSION): New protocol version
        
2002-07-02  Dick Porter  <dick@ximian.com>

        * 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

        * 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  <dick@ximian.com>

        * 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 <jarek@atm.com.pl> for pointing out the bogosity.

2002-06-10  Jaroslaw Kowalski <jarek@atm.com.pl>

        * sockets.c, daemon-messages.c: Prevent SIGPIPE from being raised
        when writing to a closed socket.

2002-06-08  Jeffrey Stedfast  <fejj@ximian.com>

        * mono-mutex.c (mono_once): New convenience function for my
        previous fix.

        * mutexes.c: 
        * io.c: 
        * events.c: 
        * atomic.c: Use mono_once() rather than pthread_once().

2002-06-06  Jeffrey Stedfast  <fejj@ximian.com>

        * 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 <lupus@ximian.com>

        * atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).

Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>

        * 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 <lupus@ximian.com>

        * daemon-messages.c: work-around MSG_NOSIGNAL missing on some
        platforms.

2002-05-15  Dick Porter  <dick@ximian.com>

        * wait.c: Fix a deadlock in WaitForMultipleObjects

2002-05-14  Dick Porter  <dick@ximian.com>

        * Makefile.am: Remove now-unused file wait-private.h

2002-05-08  Dick Porter  <dick@ximian.com>

        * 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  <miguel@ximian.com>

        * 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  <dihlewis@yahoo.co.uk>

        * io.c: CreateFile sets win32 last error.

        * 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  <fejj@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dihlewis@yahoo.co.uk>

        * io.c: unitialized pointer in GetCurrentDirectory.

Sat Apr 20 13:37:39 CEST 2002 Paolo Molaro <lupus@ximian.com>

        * 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 <lupus@ximian.com>

        * timed-thread.c: avoid race condition when setting the thread to
        detached.

2002-04-16  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * atomic.h: Explanatory comment about lack of 80386 support

2002-04-15  Dick Porter  <dick@ximian.com>

        * 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 <lupus@ximian.com>

        * unicode.c: fix unicode_len() to not access uninitialized memory
        (and updated to conform to mono code style).

        * io.c: EEXISTS is ignored for directory creation.
        * mono-mutex.h: remove silly "pragma }" that emacs users insert

        Fix a ms to ns conversion magnitude thinko.

2002-03-21  Dick Porter  <dick@ximian.com>

        * 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 <dihlewis@yahoo.co.uk>
