Grasshopper now uses csproj instead of vmwcsproj

[mono.git] / mono / io-layer / ChangeLog

Mon Feb 12 15:50:24 CET 2007 Paolo Molaro <lupus@ximian.com>

        * shared.c: exit if semaphores can't be created (bug #80616).

2007-02-01  Geoff Norton  <gnorton@customerdna.com>

        * collection.c: NetBSD doesn't define PTHREAD_STACK_MIN.

2007-01-26  Dick Porter  <dick@ximian.com>

        * 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 <mason@broadcom.com

        * atomic.h: add locking primitives for MIPS.
        
2007-01-11  Dick Porter  <dick@ximian.com>

        * 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  <miguel@novell.com>

        * io-portability.c (find_file): Fix a coverity warning (scanning
        being unassigned).   

2006-12-31  Miguel de Icaza  <miguel@novell.com>

        * 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 <lupus@ximian.com>

        * processes.c: moved a free on the error path.

Thu Dec 14 21:42:39 CET 2006 Paolo Molaro <lupus@ximian.com>

        * processes.c: fixed a few memory leaks when executing
        processes.

Mon Nov 27 13:12:17 GMT 2006 Paolo Molaro <lupus@ximian.com>

        * atomic.h: fix arm compare and exchange (bug #78500).

2006-11-23  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * processes.c: Fix const correctness and typos that caused memory
        corruption. 
        
2006-11-17  Miguel de Icaza  <miguel@novell.com>

        * processes.c (ShellExecuteEx): Check error after CreateProcess,
        thanks to Dick for pointing this out. 

2006-11-16  Miguel de Icaza  <miguel@novell.com>

        * 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  <dick@ximian.com>

        * 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  <miguel@novell.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * io.c (GetFileAttributes): Force symlinks to directories to be
        returned as a regular file.  Fixes bug 79733.

2006-10-18  Miguel de Icaza  <miguel@novell.com>

        * io-portability.c (find_in_dir): First string dup, then closedir.

2006-10-12  Dick Porter  <dick@ximian.com>

        * 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 <tsv@solvo.ru>

        * 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  <vargaz@gmail.com>

        * 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  <miguel@novell.com>

        * io-portability.c (find_file): Rename from
        MONO_IO_PORTABILITY_HELP to MONO_IOMAP.

2006-10-03  Dick Porter  <dick@ximian.com>

        * 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  <vargaz@gmail.com>

        * critical-sections.h critical-sections.c: Make Enter/LeaveCriticalSection a macro
        since they are perf critical.

        * atomic.h: Applied patch from Jakub Boqusz <qboosh@pld-linux.org>.
        Add atomic ops implementation for alpha.

2006-08-11  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * shared.c (_wapi_shm_file): Remove '/' characters from the uname
        results.  Fixes bug 78917.

2006-07-20  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * processes.c (CreateProcess): Don't change directory unless a new
        one has been specified.  Fixes bug 78751.

2006-07-06  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * io.c (GetFileAttributes, GetFileAttributesEx): Cope with
        dangling symlinks.  Fixes bug 78664.

2006-06-23  Dick Porter  <dick@ximian.com>

        * 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 <neale@sinenomine.net>

        * atomic.h: More tinkering with InterlockedExchange/InterlockedCompareExchange
        for s390/s390x.

2006-06-14 Neale Ferguson <neale@sinenomine.net>

        * 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  <dick@ximian.com>

        * processes.c: Don't run the atexit handlers when bailing out
        of a fork/exec.

2006-06-14  Dick Porter  <dick@ximian.com>

        * 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 <neale@sinenomine.net>

        * atomic.h: Fix atomic operations for s390x (not really broken 
        but changed to use full 64-bit opcodes).

2006-05-24  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <miguel@novell.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * threads.c (GetCurrentThread): Reference the handle if we return
        an already-known thread.

2006-04-07  Dick Porter  <dick@ximian.com>

        * processes.c: Fix build for older glib.

2006-04-06  Dick Porter  <dick@ximian.com>
        
        * 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  <dick@ximian.com>

        * shared.c: Fix parameters in semctl () call.

2006-03-28  Zoltan Varga  <vargaz@gmail.com>

        * atomic.h atomic.c: Applied patch from David S. Miller 
        <davem@davemloft.net>: 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * wait.c: speed up WaitFor* when the timeout is 0.

2006-03-03  Dick Porter  <dick@ximian.com>

        * processes.c (ShellExecuteEx): Cope when some of the parameters
        are NULL.

2006-02-27  Dick Porter  <dick@ximian.com>

        * 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 <lupus@ximian.com>

        * *.h, *.h: patch from Dick to make Linuxthreads systems work again.

2006-02-22  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * handles-private.h: 
        * handles.c: Check handle values passed to array lookups.  Fixes
        bug 77572.

2006-02-09  Dick Porter  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <martin@ximian.com>

        * 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 <neale@sinenomine.net>

        * atomic.h: Correct s390x definitions and eliminate compiler warnings.

2006-01-03  Sebastien Pouliot  <sebastien@ximian.com>

        * io.c: Patch _wapi_stat_to_file_attributes against bug #76966, where
        sockets could be considered as directory.

2005-12-23  Dick Porter  <dick@ximian.com>


        * 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  <dick@ximian.com>

        * 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 <lupus@ximian.com>

        * shared.c: fallback to private mmap when shared mmap doesn't work
        (like on jffs).

2005-12-06  Dick Porter  <dick@ximian.com>

        * wapi-private.h: 
        * handles.c: 
        * semaphore-private.h: 
        * semaphores.c: Implement named semaphores

2005-11-24  Dick Porter  <dick@ximian.com>

        * processes.c (GetProcessId): Implement GetProcessId()

2005-11-17  Dick Porter  <dick@ximian.com>

        * processes.h: 
        * processes.c: Implement ShellExecuteEx as a wrapper around
        CreateProcess.

2005-11-11  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * sockets.c (ioctlsocket): Use select instead of if to avoid a
        type promotion problem on 64bit freebsd.  Based on patch by Lou
        Kamenov <kamenovl@gmail.com>, fixes bug 76447.

2005-11-04  Dick Porter  <dick@ximian.com>

        * io.c (file_write): Only do the file locking if
        MONO_STRICT_IO_EMULATION is set.

2005-10-21  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * io.c: removed NO_SIGPIPE macro.
        * sockets.c: no need for MSG_NOSIGNAL or ignoring SIGPIPE.

2005-10-11  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * handles.c: Fix several race conditions

2005-10-11 Miguel de Icaza <miguel@novell.com>

        * io.c: no need to block SIGPIPE anymore, as it is ignored.

2005-10-05  Dick Porter  <dick@ximian.com>

        * 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  <sebastien@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * collection.c: 
        * processes.c: Periodically waitpid for known process IDs.  Fixes
        bug 74870.

2005-09-15 Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <vargaz@gmail.com>

        * atomic.h: Add support for intel icc.

2005-08-25  Zoltan Varga  <vargaz@gmail.com>

        * io-layer.h: Include winbase.h not WinBase.h.

2005-08-19  Dick Porter  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * error.c: map ENOENT to WSAECONNREFUSED. It might happen when
        connecting to unix sockets. Closes bug #75632.

2005-07-05  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * shared.c (_wapi_shm_semaphores_init): Add some helpful error
        messages when semget () fails due to lack of resources.

2005-06-21  Dick Porter  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <duncan@novell.com>

        * *.h: Added G_BEGIN_DECLS and G_END_DECLS where appropriate to
        all public headers. Fixes #74919.

2005-05-30  Zoltan Varga  <vargaz@freemail.hu>

        * atomic.h: Add IA64 atomic ops.

2005-05-26 Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * shared.c: forgot to ignore a warning.

2005-05-10 Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * shared.c: don't display warnings after reboots.

2005-05-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <lluis@novell.com>

        * 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 <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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 <lupus@ximian.com>

        * 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 <gonzalo@ximian.com>

        * handles.c: fix handle returned in _wapi_handle_search_handle. Dick
        pointed it out.

2005-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * collection.c: FreeBSD needs more than PTHREAD_STACK_MIN

2005-04-14  Raja R Harinath  <rharinath@novell.com>

        * wapi-private.h: Remove reference to 'daemon-private.h'.

Wed Apr 13 13:12:33 EDT 2005 Paolo Molaro <lupus@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * io.c (FindFirstFile): Fix bugs introduced with the merge (bug
        74586)

2005-04-12  Dick Porter  <dick@ximian.com>
        
        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 <gonzalo@ximian.com>

        * 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  <vargaz@freemail.hu>

        * atomic.c (InterlockedIncrement): Fix fallback implementation of
        InterlockedIncrement and InterlockedDecrement. Fixes #74228.

2005-03-29  Sebastien Pouliot  <sebastien@ximian.com>

        * io-layer.h: Add required header files for compiling with VS.NET.

2005-03-17 Miguel de Icaza <miguel@novell.com>

        * io.c: don't fail on NFS when there are no more locks available.

2005-03-09  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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
        <tjain@novell.com> and Hemanth Yamijala <YHemanth@novell.com>.

2005-03-07  Dick Porter  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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 <gonzalo@ximian.com>

        * io.c: another leftover.

Fri Feb 18 17:37:29 CET 2005 Paolo Molaro <lupus@ximian.com>

        * io.c: fixed logic in checking errno in rev 40815.

Fri Feb 18 16:00:29 CET 2005 Paolo Molaro <lupus@ximian.com>

        * 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 <lupus@ximian.com>

        * 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 <lupus@ximian.com>

        * threads.c: make people test with 1 MB stack per thread.

2005-01-17  Dick Porter  <dick@ximian.com>

        * timefuncs.h: Make WapiFileTime endian-aware, as it's often
        cast to and from 64bit ints.  Fixes bug 71213.

2005-01-11  Dick Porter  <dick@ximian.com>

        * error.c (errno_to_WSA): Add EADDRNOTAVAIL error code
        translation.

Mon Jan 10 16:15:19 EST 2005 Neale Ferguson <nealeferguson@earthlink.net>

        * atomic.h: Fix functions on s390.

Mon Jan 10 20:30:19 CET 2005 Paolo Molaro <lupus@ximian.com>

        * atomic.h: fix some functions on ppc (tests/interlocked.cs).

2005-01-10  Dick Porter  <dick@ximian.com>

        * 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  <bmaurer@ximian.com>

        * 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 <lupus@ximian.com>

        * threads.c, threads.h: add accessor to get the pthread_key_t for
        a tls id.

2004-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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 <Neale.Ferguson@SoftwareAG-usa.com>

        * atomic.h : Fix InterlockedCompareExchange for s390/s390x.

2004-12-01 Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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 <gonzalo@ximian.com>

        * 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  <bmaurer@ximian.com>

        * system.c: Add support for getting the # of cpus.

2004-09-28  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * error.c:
        * io.c: Set error codes everywhere.

2004-09-06  Dick Porter  <dick@ximian.com>

        * 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  <vargaz@freemail.hu>

        * shared.c (_wapi_shm_file): Fix leaking of filename.

2004-08-19  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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 <Neale.Ferguson@SoftwareAG-usa.com>

        * atomic.h: add support for 64-bit S/390

2004-07-22  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <bmaurer@ximian.com>

        * threads.c: register roots for gc

2004-07-08  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <vargaz@freemail.hu>

        * mono-mutex.h atomic.h: Add G_GNUC_UNUSED to static inline functions
        to prevent warnings.

2004-06-24  Dick Porter  <dick@ximian.com>

        * mutexes.c: Indicate when a named mutex was reused

2004-06-24  Dick Porter  <dick@ximian.com>

        * 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 <lupus@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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  <lluis@ximian.com>

        * threads.c: Implemented SleepEx.
        * threads.h: Fixed SleepEx signature.

2004-06-03  Miguel de Icaza  <miguel@ximian.com>

        * threads.c: When running under valgrind, do not allocate too much
        stack, as Valgrind default is 1 meg.

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:

        * 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>

        * 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

        * 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>

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>

        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>

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>

        * 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>

        * 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>

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
        the daemon, it's now built into the library.

2002-06-25  Dick Porter  <dick@ximian.com>

        * 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  <dick@ximian.com>

        * 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.

        * handles.c:
        * error.c: 
        * critical-sections.c:

        * 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.

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

        * 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).

Fri Mar 29 17:15:11 CET 2002 Paolo Molaro <lupus@ximian.com>

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

        * unicode.h, unicode.c: changed to gunichar2
        * io.h, io.c: changed strings to gunichar2*, added

        * threads.c: Fix a race condition where a thread can start and

        why the handle couldn't be initialised beforehand, so do so)

        Fix a ms to ns conversion magnitude thinko.
