| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on ideas from Kim F. Storm <storm@cua.dk>, see http://lists.gnu.org/archive/html/emacs-devel/2006-12/msg00873.html. src/w32proc.c (reader_thread): If the FILE_CONNECT flag is set, call '_sys_wait_connect'. If it returns STATUS_CONNECT_FAILED, exit the thread with code 2. (sys_select): Support 'wfds' in addition to 'rfds'. If a descriptor in 'wfds' has its bit set, but the corresponding fd_info member doesn't have its FILE_CONNECT flag set, ignore the descriptor. Otherwise, acknowledge a successful non-blocking connect by resetting the FILE_CONNECT flag and setting cp->status to STATUS_READ_ACKNOWLEDGED. src/w32.h (STATUS_CONNECT_FAILED): New enumeration value. (struct _child_process): New member 'errcode'. (FILE_CONNECT): New flag. (_sys_wait_connect): Add prototype. src/w32.c (pfn_WSAEnumNetworkEvents): New function pointer.

(_sys_read_ahead): Add debug message if this function is called for a descriptor that waits for a non-blocking connect to complete. (_sys_wait_connect): New function. (sys_read): Support STATUS_CONNECT_FAILED. Return the error code recorded by _sys_wait_connect when the non-blocking connect failed. Don't call WSAGetLastError before a call to set_errno had a chance to use its value, since WSAGetLastError clears the last error. nt/inc/ms-w32.h (BROKEN_NON_BLOCKING_CONNECT): Don't define.

Improve the format of error messages and include the file name in them where appropriate. (Fplay_sound_internal) [WINDOWSNT]: Make the MS-Windows branch call play-sound-functions, per documentation. src/w32.c (w32_get_long_filename, w32_get_short_filename): Constify the input file name arguments. src/w32.h (w32_get_long_filename, w32_get_short_filename): Update prototypes.

(filename_to_utf16, filename_from_utf16, filename_to_ansi) (filename_from_ansi, sys_link, check_windows_init_file): Call MultiByteToWideChar and WideCharToMultiByte through pointers. This is required on Windows 9X, where we dynamically load UNICOWS.DLL which has their non-stub implementations. (maybe_load_unicows_dll): Assign addresses to these 2 function pointers after loading UNICOWS.DLL. src/w32fns.c (Fx_file_dialog, Fw32_shell_execute) [!CYGWIN]: Call MultiByteToWideChar and WideCharToMultiByte through function pointers. src/w32.h (pMultiByteToWideChar, pWideCharToMultiByte): New declarations.

This fixes a failure to start up because Emacs cannot find term/w32-win.el. Reported by oslsachem <oslsachem@gmail.com>. src/w32font.c [WINDOWSNT]: Include w32.h. (w32_load_unicows_or_gdi32): Call maybe_load_unicows_dll, instead of implementing the same stuff. Remove now unused g_b_init_is_windows_9x. src/w32.h (maybe_load_unicows_dll): Add prototype. nt/runemacs.c (ensure_unicows_dll): Don't tell in the message box that "emacs -nw" can do without UNICOWS.DLL on Windows 9X.

(_sys_wait_accept): Wait for accept event in a loop with a finite timeout, instead of waiting indefinitely. Will hopefully avoid hanging during exit because WSACleanup deadlocks waiting for the event object to be released. src/w32proc.c (release_listen_threads): New function, signals all the reader threads that listen for connections to stop waiting. src/w32.h (release_listen_threads): Add prototype.
* Make file descriptors close-on-exec when possible.Paul Eggert2013-07-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies Emacs a bit, since it no longer needs to worry about closing file descriptors by hand in some cases. It also fixes some unlikely races. Not all such races, as libraries often open files internally without setting close-on-exec, but it's an improvement. * admin/merge-gnulib (GNULIB_MODULES): Add fcntl, pipe2. (GNULIB_TOOL_FLAGS): Avoid binary-io, close. Do not avoid fcntl. * configure.ac (mkostemp): New function to check for.

(MAX_LFINFO): New top-level constant. (lock_info_type): Remove members pid, boot_time. Add members at, dot, colon. Change user member to be the entire buffer, not a pointer. This allows us to handle the case where a foreign pid or boot time exceeds the local range. All uses changed. (LINKS_MIGHT_NOT_WORK): New constant. (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing. (defined_WINDOWSNT): Remove. (MAKE_LOCK_NAME, file_in_lock_file_name): Always use .#FILE (not .#-FILE) for the file lock, even if it is a regular file. (rename_lock_file): New function. (create_lock_file): Use it. (create_lock_file, read_lock_data): Prefer a symbolic link for the lock file, falling back on a regular file if symlinks don't work. Do not try to create symlinks on MS-Windows, due to security hassles. Stick with POSIXish functions (open, read, write, close, fchmod, readlink, symlink, link, rename, unlink, mkstemp) when creating locks, as a GNUish host may be using a Windowsish file system, and cannot use MS-Windows-only system calls. Fall back on mktemp if mkstemp doesn't work. Don't fail merely because of a symlink-contents length limit in the current file system; fall back on regular files. Increase the symlink contents length limit to 8 KiB, this should be big enough for any real use and doesn't crunch the stack. (create_lock_file, lock_file_1, read_lock_data): Simplify allocation of lock file buffers now that they fit in 8 KiB. (lock_file_1): Return error number, not bool. All callers changed. (ELOOP): New macro, if not already defined. (read_lock_data): Return size of lock file contents, not Lisp object. All callers changed. Handle a race condition if some other process replaces a regular-file lock with a symlink lock or vice versa, while we're trying to read the lock. (current_lock_owner): Parse contents more carefully, to help avoid confusing a regular-file lock with some other application's use of the file. Check for lock file contents being too long, or not parsing correctly. (current_lock_owner, lock_file): Allow foreign pid and boot times that exceed the local range. (current_lock_owner, lock_if_free, lock_file): Simplify allocation of lock file contents. * src/w32.c (sys_rename_replace): New function, containing most of the contents of the old sys_rename. (sys_rename): Use it. (fchmod): New dummy function. * src/w32.h (sys_rename_replace, fchmod): New decls. Fixes: debbugs:13807
