* doc.c: Fix minor memory and file descriptor leaks.

[emacs.git] / src / ChangeLog

2013-07-18  Paul Eggert  <eggert@cs.ucla.edu>

        * doc.c: Fix minor memory and file descriptor leaks.
        * doc.c (get_doc_string): Fix memory leak when doc file absent.
        (get_doc_string, Fsnarf_documentation):
        Fix file descriptor leak on error.

        * term.c: Fix minor fdopen-related file descriptor leaks.
        * term.c (Fresume_tty) [!MSDOS]: Close fd if fdopen (fd) fails.
        (init_tty) [!DOS_NT]: Likewise.  Also close fd if isatty (fd) fails.

        * charset.c: Fix file descriptor leaks and errno issues.
        Include <errno.h>.
        (load_charset_map_from_file): Don't leak file descriptor on error.
        Use plain record_xmalloc since the allocation is larger than
        MAX_ALLOCA; that's simpler here.  Simplify test for exhaustion
        of entries.
        * eval.c (record_unwind_protect_nothing):
        * fileio.c (fclose_unwind):
        New functions.
        * lread.c (load_unwind): Remove.  All uses replaced by fclose_unwind.
        The replacement doesn't block input, but that no longer seems
        necessary.

2013-07-17  Paul Eggert  <eggert@cs.ucla.edu>

        * lread.c: Fix file descriptor leaks and errno issues.
        (Fload): Close some races that leaked fds or streams when 'load'
        was interrupted.
        (Fload, openp): Report error number of last nontrivial failure to open.
        ENOENT counts as trivial.
        * eval.c (do_nothing, clear_unwind_protect, set_unwind_protect_ptr):
        New functions.
        * fileio.c (close_file_unwind): No need to test whether FD is nonnegative,
        now that the function is always called with a nonnegative arg.
        * lisp.h (set_unwind_protect_ptr, set_unwind_protect_int): Remove.
        All uses replaced with ...
        (clear_unwind_protect, set_unwind_protect_ptr): New decls.

        A few more minor file errno-reporting bugs.
        * callproc.c (Fcall_process):
        * doc.c (Fsnarf_documentation):
        * fileio.c (Frename_file, Fadd_name_to_file, Fmake_symbolic_link):
        * process.c (set_socket_option):
        Don't let a constructor trash errno.
        * doc.c: Include <errno.h>.

2013-07-16  Juanma Barranquero  <lekktu@gmail.com>

        * w32fns.c (unwind_create_tip_frame): Fix declaration.

2013-07-16  Paul Eggert  <eggert@cs.ucla.edu>

        Fix w32 bug with call-process-region (Bug#14885).
        * callproc.c (Fcall_process_region): Pass nil, not "/dev/null",
        to Fcall_process when the input is empty.  This simplifies the
        code a bit.  It makes no difference on POSIXish platforms but
        apparently it fixes a bug on w32.

        Fix bug where insert-file-contents closes a file twice. (Bug#14839).
        * fileio.c (close_file_unwind): Don't close if FD is negative;
        this can happen when unwinding a zapped file descriptor.
        (Finsert_file_contents): Unwind-protect the fd before the point marker,
        in case Emacs runs out of memory between the two unwind-protects.
        Don't trash errno when closing FD.
        Zap the FD in the specpdl when closing it, instead of deferring
        the removal of the unwind-protect; this fixes a bug where a child
        function unwinds the stack past us.

        New unwind-protect flavors to better type-check C callbacks.
        This also lessens the need to write wrappers for callbacks,
        and the need for make_save_pointer.
        * alloca.c (free_save_value):
        * atimer.c (run_all_atimers):
        Now extern.
        * alloc.c (safe_alloca_unwind):
        * atimer.c (unwind_stop_other_atimers):
        * keyboard.c (cancel_hourglass_unwind) [HAVE_WINDOW_SYSTEM]:
        * menu.c (cleanup_popup_menu) [HAVE_NS]:
        * minibuf.c (choose_minibuf_frame_1):
        * process.c (make_serial_process_unwind):
        * xdisp.h (pop_message_unwind):
        * xselect.c (queue_selection_requests_unwind):
        Remove no-longer-needed wrapper.  All uses replaced by the wrappee.
        * alloca.c (record_xmalloc):
        Prefer record_unwind_protect_ptr to record_unwind_protect with
        make_save_pointer.
        * alloca.c (Fgarbage_collect):
        Prefer record_unwind_protect_void to passing a dummy.
        * buffer.c (restore_buffer):
        * window.c (restore_window_configuration):
        * xfns.c, w32fns.c (do_unwind_create_frame)
        New wrapper.  All record-unwind uses of wrappee changed.
        * buffer.c (set_buffer_if_live):
        * callproc.c (call_process_cleanup, delete_temp_file):
        * coding.c (code_conversion_restore):
        * dired.c (directory_files_internal_w32_unwind) [WINDOWSNT]:
        * editfns.c (save_excursion_restore)
        (subst_char_in_region_unwind, subst_char_in_region_unwind_1)
        (save_restriction_restore):
        * eval.c (restore_stack_limits, un_autoload):
        * fns.c (require_unwind):
        * keyboard.c (recursive_edit_unwind, tracking_off):
        * lread.c (record_load_unwind, load_warn_old_style_backquotes):
        * macros.c (pop_kbd_macro, restore_menu_items):
        * nsfns.m (unwind_create_frame):
        * print.c (print_unwind):
        * process.c (start_process_unwind):
        * search.c (unwind_set_match_data):
        * window.c (select_window_norecord, select_frame_norecord):
        * xdisp.c (unwind_with_echo_area_buffer, unwind_format_mode_line)
        (fast_set_selected_frame):
        * xfns.c, w32fns.c (unwind_create_tip_frame):
        Return void, not a dummy Lisp_Object.  All uses changed.
        * buffer.h (set_buffer_if_live): Move decl here from lisp.h.
        * callproc.c (call_process_kill):
        * fileio.c (restore_point_unwind, decide_coding_unwind)
        (build_annotations_unwind):
        * insdel.c (Fcombine_after_change_execute_1):
        * keyboard.c (read_char_help_form_unwind):
        * menu.c (unuse_menu_items):
        * minibuf.c (run_exit_minibuf_hook, read_minibuf_unwind):
        * sound.c (sound_cleanup):
        * xdisp.c (unwind_redisplay):
        * xfns.c (clean_up_dialog):
        * xselect.c (x_selection_request_lisp_error, x_catch_errors_unwind):
        Accept no args and return void, instead of accepting and returning
        a dummy Lisp_Object.  All uses changed.
        * cygw32.c (fchdir_unwind):
        * fileio.c (close_file_unwind):
        * keyboard.c (restore_kboard_configuration):
        * lread.c (readevalllop_1):
        * process.c (wait_reading_process_output_unwind):
        Accept int and return void, rather than accepting an Emacs integer
        and returning a dummy object.  In some cases this fixes an
        unlikely bug when the corresponding int is outside Emacs integer
        range.  All uses changed.
        * dired.c (directory_files_internal_unwind):
        * fileio.c (do_auto_save_unwind):
        * gtkutil.c (pop_down_dialog):
        * insdel.c (reset_var_on_error):
        * lread.c (load_unwind):
        * xfns.c (clean_up_file_dialog):
        * xmenu.c, nsmenu.m (pop_down_menu):
        * xmenu.c (cleanup_widget_value_tree):
        * xselect.c (wait_for_property_change_unwind):
        Accept pointer and return void, rather than accepting an Emacs
        save value encapsulating the pointer and returning a dummy object.
        All uses changed.
        * editfns.c (Fformat): Update the saved pointer directly via
        set_unwind_protect_ptr rather than indirectly via make_save_pointer.
        * eval.c (specpdl_func): Remove.  All uses replaced by definiens.
        (unwind_body): New function.
        (record_unwind_protect): First arg is now a function returning void,
        not a dummy Lisp_Object.
        (record_unwind_protect_ptr, record_unwind_protect_int)
        (record_unwind_protect_void): New functions.
        (unbind_to): Support SPECPDL_UNWIND_PTR etc.
        * fileio.c (struct auto_save_unwind): New type.
        (do_auto_save_unwind): Use it.
        (do_auto_save_unwind_1): Remove; subsumed by new do_auto_save_unwind.
        * insdel.c (struct rvoe_arg): New type.
        (reset_var_on_error): Use it.
        * lisp.h (SPECPDL_UNWIND_PTR, SPECPDL_UNWIND_INT, SPECPDL_UNWIND_VOID):
        New constants.
        (specbinding_func): Remove; there are now several such functions.
        (union specbinding): New members unwind_ptr, unwind_int, unwind_void.
        (set_unwind_protect_ptr): New function.
        * xselect.c: Remove unnecessary forward decls, to simplify maintenance.

        Be simpler and more consistent about reporting I/O errors.
        * fileio.c (Fcopy_file, Finsert_file_contents, Fwrite_region):
        Say "Read error" and "Write error", rather than "I/O error", or
        "IO error reading", or "IO error writing", when a read or write
        error occurs.
        * process.c (Fmake_network_process, wait_reading_process_output)
        (send_process, Fprocess_send_eof, wait_reading_process_output):
        Capitalize diagnostics consistently.  Put "failed foo" at the
        start of the diagnostic, so that we don't capitalize the
        function name "foo".  Consistently say "failed" for such
        diagnostics.
        * sysdep.c, w32.c (serial_open): Now accepts Lisp string, not C string.
        All callers changed.  This is so it can use report_file_error.
        * sysdep.c (serial_open, serial_configure): Capitalize I/O
        diagnostics consistently as above.

        * fileio.c (report_file_errno): Fix errno reporting bug.
        If the file name is neither null nor a pair, package it up as a
        singleton list.  All callers changed, both to this function and to
        report_file_error.  This fixes a bug where the memory allocator
        invoked by list1 set errno so that the immediately following
        report_file_error reported the wrong errno value.

        Fix minor problems found by --enable-gcc-warnings.
        * frame.c (Fhandle_focus_in, Fhandle_focus_out): Return a value.
        * keyboard.c (kbd_buffer_get_event): Remove unused local.

2013-07-16  Jan Djärv  <jan.h.d@swipnet.se>

        * xterm.c (x_focus_changed): Always generate FOCUS_IN_EVENT.
        Set event->arg to Qt if switch-event shall be generated.
        Generate FOCUS_OUT_EVENT for FocusOut if this is the focused frame.

        * termhooks.h (enum event_kind): Add FOCUS_OUT_EVENT.

        * nsterm.m (windowDidResignKey): If this is the focused frame, generate
        FOCUS_OUT_EVENT.

        * keyboard.c (Qfocus_in, Qfocus_out): New static objects.
        (make_lispy_focus_in, make_lispy_focus_out): Declare and define.
        (kbd_buffer_get_event): For FOCUS_IN, make a focus_in event if no
        switch frame event is made.  Check ! NILP (event->arg) if X11 (moved
        from xterm.c). Make focus_out event for FOCUS_OUT_EVENT if NS or X11
        and there is a focused frame.
        (head_table): Add focus-in and focus-out.
        (keys_of_keyboard): Add focus-in and focus-out to Vspecial_event_map,
        bind to handle-focus-in/out.

        * frame.c (Fhandle_focus_in, Fhandle_focus_out): New functions.
        (Fhandle_switch_frame): Call Fhandle_focus_in.
        (syms_of_frame): defsubr handle-focus-in/out.

2013-07-16  Paul Eggert  <eggert@cs.ucla.edu>

        Fix porting bug to older POSIXish platforms (Bug#14862).
        * sysdep.c (emacs_pipe): New function, that implements
        pipe2 (fd, O_CLOEXEC) even on hosts that lack O_CLOEXEC.
        This should port better to CentOS 5 and to Mac OS X 10.6.
        All calls to pipe2 changed.

        Prefer list1 (X) to Fcons (X, Qnil) when building lists.
        This makes the code easier to read and the executable a bit smaller.
        Do not replace all calls to Fcons that happen to create lists,
        just calls that are intended to create lists.  For example, when
        creating an alist that maps FOO to nil, use list1 (Fcons (FOO, Qnil))
        rather than list1 (list1 (FOO)) or Fcons (Fcons (FOO, Qnil), Qnil).
        Similarly for list2 through list5.
        * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
        * bytecode.c (exec_byte_code):
        * callint.c (quotify_arg, Fcall_interactively):
        * callproc.c (Fcall_process, create_temp_file):
        * charset.c (load_charset_map_from_file)
        (Fdefine_charset_internal, init_charset):
        * coding.c (get_translation_table, detect_coding_system)
        (Fcheck_coding_systems_region)
        (Fset_terminal_coding_system_internal)
        (Fdefine_coding_system_internal, Fdefine_coding_system_alias):
        * composite.c (update_compositions, Ffind_composition_internal):
        * dired.c (directory_files_internal, file_name_completion)
        (Fsystem_users):
        * dispnew.c (Fopen_termscript, bitch_at_user, init_display):
        * doc.c (Fsnarf_documentation):
        * editfns.c (Fmessage_box):
        * emacs.c (main):
        * eval.c (do_debug_on_call, signal_error, maybe_call_debugger)
        (Feval, eval_sub, Ffuncall, apply_lambda):
        * fileio.c (make_temp_name, Fcopy_file, Faccess_file)
        (Fset_file_selinux_context, Fset_file_acl, Fset_file_modes)
        (Fset_file_times, Finsert_file_contents)
        (Fchoose_write_coding_system, Fwrite_region):
        * fns.c (Flax_plist_put, Fyes_or_no_p, syms_of_fns):
        * font.c (font_registry_charsets, font_parse_fcname)
        (font_prepare_cache, font_update_drivers, Flist_fonts):

        * frame.c (make_frame, Fmake_terminal_frame)
        (x_set_frame_parameters, x_report_frame_params)
        (x_default_parameter, Fx_parse_geometry):
        * ftfont.c (syms_of_ftfont):
        * image.c (gif_load):
        * keyboard.c (command_loop_1):
        * keymap.c (Fmake_keymap, Fmake_sparse_keymap, access_keymap_1)
        (Fcopy_keymap, append_key, Fcurrent_active_maps)
        (Fminor_mode_key_binding, accessible_keymaps_1)
        (Faccessible_keymaps, Fwhere_is_internal):
        * lread.c (read_emacs_mule_char):

        (read_and_dispose_of_process_output, write_queue_push)
        (send_process, exec_sentinel):
        * sound.c (Fplay_sound_internal):
        * textprop.c (validate_plist, add_properties)
        (Fput_text_property, Fadd_face_text_property)
        (copy_text_properties, text_property_list, syms_of_textprop):
        * unexaix.c (report_error):
        * unexcoff.c (report_error):
        * unexsol.c (unexec):
        * xdisp.c (redisplay_tool_bar, store_mode_line_string)
        (Fformat_mode_line, syms_of_xdisp):
        * xfaces.c (set_font_frame_param)
        (Finternal_lisp_face_attribute_values)
        (Finternal_merge_in_global_face, syms_of_xfaces):
        * xfns.c (x_default_scroll_bar_color_parameter)

        * xmenu.c (Fx_popup_dialog, xmenu_show, xdialog_show)
        (menu_help_callback, xmenu_show):
        * xml.c (make_dom):
        * xterm.c (set_wm_state):
        Prefer list1 (FOO) to Fcons (FOO, Qnil) when creating a list,
        and similarly for list2 through list5.

2013-07-15  Paul Eggert  <eggert@cs.ucla.edu>

        * callproc.c (Fcall_process_region): Fix minor race and tune.
        (create_temp_file): New function, with the temp-file-creation part
        of the old Fcall_process_region.  Use Fcopy_sequence to create the
        temp file name, rather than alloca + build_string, for simplicity.
        Don't bother to block input around the temp file creation;
        shouldn't be needed.  Simplify use of mktemp.  Use
        record_unwind_protect immediately after creating the temp file;
        this closes an unlikely race where the temp file was not removed.
        Use memcpy rather than an open-coded loop.
        (Fcall_process_region): Use the new function.  If the input is
        empty, redirect from /dev/null rather than from a newly created
        empty temp file; this avoids unnecessary file system traffic.

2013-07-14  Paul Eggert  <eggert@cs.ucla.edu>

        * filelock.c (create_lock_file) [!HAVE_MKOSTEMP && !HAVE_MKSTEMP]:
        Simplify by making this case like the other two.  This is a bit
        slower on obsolete hosts, but the extra complexity isn't worth it.

        * callproc.c (child_setup, relocate_fd) [!DOS_NT]:
        * process.c (create_process) [!DOS_NT]:
        Remove now-unnecessary calls to emacs_close.

2013-07-13  Eli Zaretskii  <eliz@gnu.org>

        * w32term.c (x_draw_hollow_cursor): Delete the brush object when
        returning early.  (Bug#14850)

        * coding.c (syms_of_coding): Set up inhibit-null-byte-detection
        and inhibit-iso-escape-detection attributes of 'undecided'.
        (Bug#14822)

2013-07-13  Paul Eggert  <eggert@cs.ucla.edu>

        * deps.mk (sysdep.o): Remove dependency on ../lib/ignore-value.h.
        Reported by Herbert J. Skuhra in
        <http://lists.gnu.org/archive/html/emacs-devel/2013-07/msg00455.html>.

        Don't lose top specpdl entry when memory is exhausted.
        * eval.c (grow_specpdl): Increment specpdl top by 1 and check for
        specpdl overflow here, to simplify callers; all callers changed.
        Always reserve an unused entry at the stack top; this avoids
        losing the top entry's information when memory is exhausted.

2013-07-12  Paul Eggert  <eggert@cs.ucla.edu>

        Clean up errno reporting and fix some errno-reporting bugs.
        * callproc.c (Fcall_process):
        * fileio.c (Fcopy_file, Finsert_file_contents, Fwrite_region):
        * process.c (create_process, Fmake_network_process):
        * unexaix.c (report_error):
        * unexcoff.c (report_error):
        Be more careful about reporting the errno of failed operations.
        The code previously reported the wrong errno sometimes.
        Also, prefer report_file_errno to setting errno + report_file_error.
        (Fcall_process): Look at openp return value rather than at path,
        as that's a bit faster and clearer when there's a numeric predicate.
        * fileio.c (report_file_errno): New function, with most of the
        old contents of report_file_error.
        (report_file_error): Use it.
        (Ffile_exists_p, Ffile_accessible_directory_p):
        Set errno to 0 when it is junk.
        * fileio.c (Faccess_file):
        * image.c (x_create_bitmap_from_file):
        Use faccessat rather than opening the file, to avoid the hassle of
        having a file descriptor open.
        * lisp.h (report_file_errno): New decl.
        * lread.c (Flocate_file_internal): File descriptor 0 is valid, too.

        Minor EBADF fixes.
        * process.c (create_process, wait_reading_process_output) [AIX]:
        Remove obsolete SIGHUP-related  code, as Emacs no longer disables
        SIGHUP, so EBADF is no longer acceptable here (it wouldn't work in
        a multithreaded environment anyway).
        * sysdep.c (emacs_close): It's not dangerous to invoke emacs_close (-1).

2013-07-12  Andreas Schwab  <schwab@linux-m68k.org>

        * image.c (x_find_image_file): Don't close a remote file handle.

2013-07-12  Paul Eggert  <eggert@cs.ucla.edu>

        Fix races with threads and file descriptors.
        * callproc.c (Fcall_process_region):
        * dired.c (open_directory):
        * emacs.c (main, Fdaemon_initialized):
        * image.c (x_find_image_file):
        * inotify.c (Finotify_rm_watch):

        * unexaix.c, unexcoff.c, unexcw.c, unexelf.c (unexec):
        * unexhp9k800.c, unexmacosx.c (unexec):
        * callproc.c (Fcall_process_region):
        Use emacs_close, not close.
        * sysdep.c (POSIX_CLOSE_RESTART, posix_close) [!POSIX_CLOSE_RESTART]:
        New macro and function, which emulates the POSIX_CLOSE_RESTART macro
        and posix_close function on current platforms (which all lack them).
        (emacs_close): Use it.  This should fix the races on GNU/Linux and
        on AIX and on future platforms that support POSIX_CLOSE_RESTART,
        and it should avoid closing random victim file descriptors on
        other platforms.

2013-07-11  Paul Eggert  <eggert@cs.ucla.edu>

        * inotify.c (uninitialized): Remove.  All uses replaced by -1.
        (Finotify_add_watch): Simplify, since -1 means uninitialized now.
        Touch up doc a bit.

        * eval.c (backtrace_function, backtrace_args): Now EXTERNALLY_VISIBLE.
        This is for .gdbinit xbacktrace.

        * sysdep.c, term.c, termcap.c, terminal.c: Integer-related minor fixes.
        * sysdep.c (emacs_get_tty): Return void, since nobody uses the value.
        (emacs_set_tty): Now static.
        * sysdep.c (emacs_set_tty, tabs_safe_p, emacs_close):
        * term.c (tty_capable_p, tty_default_color_capabilities)

        (handle_one_term_event, init_tty, maybe_fatal):
        * termcap.c (tgetst1, struct termcap_buffer, valid_filename_p)
        (tgetent, scan_file, name_match, compare_contin):
        * terminal.c (get_terminal):
        Use bool for boolean.
        * sysdep.c (init_system_name): Don't overflow stack on huge hostname.
        Prefer char to unsigned char if either will do.
        * term.c (OUTPUT, turn_on_face): Omit unnecessary casts to int.
        (tty_write_glyphs): Prefer int to unsigned.
        (produce_glyphless_glyph): Remove 2nd (unused) int arg.
        All callers changed.
        * termcap.c (tprint, main) [TEST]: Remove non-working test.

2013-07-10  Paul Eggert  <eggert@cs.ucla.edu>

        Port to C89.
        * bytecode.c (BYTE_CODE_THREADED): Do not define if __STRICT_ANSI__.
        (B__dummy__): New dummy symbol, to pacify C89.
        * dbusbind.c (XD_DEBUG_MESSAGE): Omit debugging on C89 hosts, since
        they can't grok varargs macros.
        * dispnew.c (add_window_display_history)
        (add_frame_display_history):
        * print.c (print_object):
        * xdisp.c (debug_method_add):
        Use %p printf format only for void pointers.
        * emacs.c (usage_message): New constant, replacing ...
        (USAGE1, USAGE2, USAGE3): Remove; they were too long for C89.
        (main): Adjust to usage reorg.
        * fns.c (syms_of_fns):
        * profiler.c (syms_of_profiler):
        Don't use non-constant struct initializers.
        * gnutls.h (gnutls_initstage_t):
        * lisp.h (enum Lisp_Fwd_Type):
        * lread.c (lisp_file_lexically_bound_p):
        * xsettings.c (anonymous enum):
        Remove trailing comma.
        * xsettings.c (apply_xft_settings): Use %f, not %lf; %lf is a C99ism.
        * lisp.h (ENUM_BF): Use unsigned if pedantic.
        (DEFUN_FUNCTION_INIT): New macro, that falls back on a cast if pre-C99.
        (DEFUN): Use it.
        * regex.c (const_re_char): New type, to pacify strict C89.
        All uses of 'const re_char' replaced to use it.
        * regex.h (_Restrict_): Rename from __restrict, to avoid clash
        with glibc when strict C89.  This change is imported from gnulib.
        All uses changed.
        (_Restrict_arr_): Rename from __restrict_arr, similarly.
        * sysdep.c (time_from_jiffies) [!HAVE_LONG_LONG_INT]:
        Omit GNU_LINUX implementation, since it requires long long.
        * xterm.c (x_draw_underwave):
        Do not assume the traditional order of struct's members.
        (x_term_init): Rewrite to avoid the need for non-constant structure
        initializers.

        Syntax cleanup, mostly replacing macros with functions.
`       This removes the need for the syntax_temp hack.
        * search.c: Include syntax.h after buffer.h, since syntax.h uses BVAR.
        * syntax.c (SYNTAX_INLINE): New macro.
        (SYNTAX_FLAGS_COMSTART_FIRST, SYNTAX_FLAGS_COMSTART_SECOND)
        (SYNTAX_FLAGS_COMEND_FIRST, SYNTAX_FLAGS_COMEND_SECOND)
        (SYNTAX_FLAGS_PREFIX, SYNTAX_FLAGS_COMMENT_STYLEB)

        Now constants, not macros.
        (syntax_temp) [!__GNUC__]: Remove.

        (syntax_prefix_flag_p): Move implementation of SYNTAX_PREFIX here.
        (SET_RAW_SYNTAX_ENTRY, SET_RAW_SYNTAX_ENTRY_RANGE, SYNTAX_MATCH)
        (SETUP_SYNTAX_TABLE, SETUP_SYNTAX_TABLE_FOR_OBJECT):
        Move here from syntax.h; now functions, not macros.  Except for the
        last function, these are static since only syntax.c uses them.
        (syntax_multibyte): Rename from SYNTAX_WITH_MULTIBYTE_CHECK.
        All uses changed.  Now a function, not a macro; use this fact
        to simplify the code.
        (scan_lists, scan_sexps_forward): Remove workarounds for ancient
        compiler bugs; no longer relevant.
        * syntax.h: Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
        (SYNTAX_INLINE): New macro.
        (struct gl_state_s, gl_state): Move earlier, so that it's in scope
        for the new functions.  Use bool for boolean member.
        (SYNTAX_ENTRY, SYNTAX, SYNTAX_WITH_FLAGS, SYNTAX_MATCH)
        (SYNTAX_TABLE_BYTE_TO_CHAR, UPDATE_SYNTAX_TABLE_FORWARD)

        Now extern inline functions, not macros.
        (CURRENT_SYNTAX_TABLE, SYNTAX_ENTRY_INT):
        Remove; all uses replaced by implementation.
        (syntax_temp) [!__GNUC__]: Remove decl.
        (SETUP_SYNTAX_TABLE_FOR_OBJECT): New decl.

2013-07-10  Jan Djärv  <jan.h.d@swipnet.se>

        * emacs.c (main): Fix syntax error.

2013-07-10  Paul Eggert  <eggert@cs.ucla.edu>

        Timestamp fixes for undo (Bug#14824).
        * atimer.c (schedule_atimer):
        * fileio.c (Ffile_newer_than_file_p):
        Minor cleanup: use EMACS_TIME_LT so that we can remove EMACS_TIME_GT.
        * buffer.c (buffer-undo-list): Document (t . 0) and (t . -1).
        * fileio.c (Fclear_visited_file_modtime): Move to lisp/files.el.
        (syms_of_fileio): Remove Sclear_visited_file_name.
        (Fvisited_file_modtime): Return -1, not (-1 ...), when the visited
        file doesn't exist; this avoids an ambiguity with negative timestamps.
        (Fset_visited_file_modtime): Accept -1 and 0 as time-list arg.
        * systime.h (make_emacs_time, invalid_emacs_time):
        Don't assume struct timespec layout; POSIX doesn't guarantee it.
        (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE): Remove.
        * undo.c (record_first_change): Push (visited-file-modtime) onto
        undo list rather than reimplementing it by hand, incorrectly.

2013-07-09  Ken Brown  <kbrown@cornell.edu>

        * sheap.c (STATIC_HEAP_SIZE) [__x86_64__]: Increase to 18MB.

2013-07-09  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in ($(BLD)/emacs.$(O), $(BLD)/sysdep.$(O)): Update.

2013-07-09  Paul Eggert  <eggert@cs.ucla.edu>

        Handle errno and exit status a bit more carefully.
        * callproc.c (child_setup) [!DOS_NT]: Don't try to stuff an error
        number into an exit status.  Instead, use EXIT_CANCELED.
        (child_setup) [!MSDOS]: Avoid possible deadlock with vfork.
        * callproc.c (relocate_fd):
        * emacs.c (close_output_streams, main):
        * process.c (create_process):
        * sysdep.c (sys_subshell) [!DOS_NT || !WINDOWSNT]:
        Use emacs_perror for simplicity.
        * callproc.c (relocate_fd, main):
        * sysdep.c (sys_subshell):
        Exit with EXIT_CANCELED etc., not 1, when exec setup fails.
        (shut_down_emacs): Use emacs_write, not write.
        * emacs.c, sysdep.c: Don't include <ignore-value.h>.
        * fileio.c (Fcopy_file, e_write):
        * nsterm.m (ns_select):
        * process.c (send_process):
        * sound.c (vox_write):
        Use emacs_write_sig, not emacs_write.
        * lisp.h (emacs_write_sig, emacs_perror): New decls.
        * process.h (EXIT_CANCELED), EXIT_CANNOT_INVOKE, EXIT_ENOENT):
        New constants.
        * sysdep.c (emacs_backtrace): Use emacs_write, not ignore_value
        of write.
        (emacs_full_write): New function.
        (emacs_write): Rewrite to use it.
        (emacswrite_sig, emacs_perror): New functions.
        * xrdb.c (fatal): Don't invoke perror, since errno might be garbage.

2013-07-08  Magnus Henoch <magnus.henoch@gmail.com> (tiny change).

        * image.c (imagemagick_load_image): Do not use MagickExportImagePixels
        on NS even if it is present.  Pixmap on NS is a void*.

2013-07-07  Paul Eggert  <eggert@cs.ucla.edu>

        Port to Ubuntu 10 (Bug#14803).
        Problem reported by T.V. Raman.
        * process.c (close_on_exec, accept4, process_socket):
        Define these if !HAVE_ACCEPT4, not if !SOCK_CLOEXEC.

2013-07-07  Eli Zaretskii  <eliz@gnu.org>

        * w32.c (sys_dup): Declare prototype.

        * filelock.c:

        * callproc.c [WINDOWSNT]: Include sys/socket.h.

2013-07-07  Paul Eggert  <eggert@cs.ucla.edu>

        Make file descriptors close-on-exec when possible (Bug#14803).
        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.
        * alloc.c (valid_pointer_p) [!WINDOWSNT]:
        * callproc.c (Fcall_process) [!MSDOS]:
        * emacs.c (main) [!DOS_NT]:
        * nsterm.m (ns_term_init):
        * process.c (create_process):
        Use 'pipe2' with O_CLOEXEC instead of 'pipe'.
        * emacs.c (Fcall_process_region) [HAVE_MKOSTEMP]:
        * filelock.c (create_lock_file) [HAVE_MKOSTEMP]:
        Prefer mkostemp with O_CLOEXEC to mkstemp.
        * callproc.c (relocate_fd) [!WINDOWSNT]:
        * emacs.c (main): Use F_DUPFD_CLOEXEC, not plain F_DUPFD.
        No need to use fcntl (..., F_SETFD, FD_CLOEXEC), since we're
        now using pipe2.
        * filelock.c (create_lock_file) [! HAVE_MKOSTEMP]:
        Make the resulting file descriptor close-on-exec.
        * lisp.h, lread.c, process.c (close_load_descs, close_process_descs):
        * lread.c (load_descriptor_list, load_descriptor_unwind):
        Remove; no longer needed.  All uses removed.
        * process.c (SOCK_CLOEXEC): Define to 0 if not supplied by system.
        (close_on_exec, accept4, process_socket) [!SOCK_CLOEXEC]:
        New functions.
        (socket) [!SOCK_CLOEXEC]: Supply a substitute.
        (Fmake_network_process, Fnetwork_interface_list):
        (Fnetwork_interface_info, server_accept_connection):
        Make newly-created socket close-on-exec.
        * sysdep.c (emacs_open, emacs_fopen):
        Make new-created descriptor close-on-exec.
        * w32.c (fcntl): Support F_DUPFD_CLOEXEC well enough for Emacs.
        * w32.c, w32.h (pipe2): Rename from 'pipe', with new flags arg.

2013-07-07  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (sendEvent:): Propagate keyboard events to modal windows
        for NS_IMPL_GNUSTEP.

2013-07-07  Paul Eggert  <eggert@cs.ucla.edu>

        Fix openp errno handling.
        * callproc.c (Fcall_process): Preserve openp errno around close.
        * lread.c (openp): Set errno when returning -1, as some callers
        expect this.

2013-07-06  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (sendEvent:): Handle NSAPP_DATA2_RUNFILEDIALOG.

        * nsterm.h (NSSavePanel): Update comment.

        * nsfns.m: Remove panelOK.
        (ns_fd_data): New.
        (ns_run_file_dialog): New function.
        (Fns_read_file_name): Fill in ns_fd_data, post an event and start the
        event loop, so file dialog is popped up by ns_run_file_dialog, called
        by sendEvent (Bug#14578).
        (EmacsSavePanel, EmacsOpenPanel): Remove ok and cancel methods.

2013-07-06  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (default_line_pixel_height): New function.
        (pos_visible_p, move_it_vertically_backward, try_scrolling)
        (try_cursor_movement, redisplay_window, try_window)
        (try_window_id): Use it instead of FRAME_LINE_HEIGHT.  (Bug#14771)

        * window.c (window_scroll_pixel_based): use
        default_line_pixel_height.

        * dispextern.h (default_line_pixel_height): Add prototype.

        * frame.c (x_set_line_spacing): Accept a float value for
        line-spacing parameter, per the documentation.

        * data.c (Fmultibyte_string_p): Doc fix.

2013-07-05  Paul Eggert  <eggert@cs.ucla.edu>

        Use emacs_open more consistently when opening files.
        This handles EINTR more consistently now, and makes it easier
        to introduce other uniform changes to file descriptor handling.
        * src/systdio.h: New file.
        * src/buffer.c (mmap_init):
        * cygw32.c (chdir_to_default_directory):

        * w32term.c (w32_initialize) [CYGWIN]:
        * xfaces.c (Fx_load_color_file):
        Use emacs_open instead of plain open, and emacs_fopen instead of
        plain fopen.
        * dispnew.c, fileio.c, image.c, keyboard.c, lread.c, print.c, sysdep.c:
        * xfaces.c: Include sysstdio.h rather than stdio.h, for emacs_fopen.
        * callproc.c (default_output_mode): New constant.
        (Fcall_process): Use it to call emacs_open instead of plain creat.
        * dispnew.c (Fopen_termscript): Fix minor race in opening termscript.
        * sysdep.c (emacs_open): Add commentary and don't call file name "path".

        Remove duplicate #include directives.
        * alloc.c [GC_MARK_STACK == GC_USE_GCPROS_CHECK_ZOMBIES]:

        Scale ImageMagick images more carefully.
        * image.c (scale_image_size) [HAVE_IMAGEMAGICK]: New function.
        (compute_image_size): Use it.  Define only if HAVE_IMAGEMAGICK.
        Be more careful about avoiding undefined behavior after
        integer overflow and division by zero.

2013-07-04  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        * w32fns.c (Qgeometry, Qworkarea, Qmm_size, Qframes): New variables.

        (MonitorEnum_Proc, EnumDisplayMonitors_Proc): New prototypes.
        (enum_display_monitors_fn): New variable.
        (globals_of_w32fns): Initialize it.
        (Fx_display_pixel_width, Fx_display_pixel_height)
        (Fx_display_mm_height, Fx_display_mm_width): Mention behavior on
        multi-monitor setups in docstrings.
        (Fx_display_mm_height, Fx_display_mm_width): Approximate whole
        screen size by primary monitor's millimeter per pixel.
        (w32_monitor_enum, w32_display_monitor_attributes_list)
        (w32_display_monitor_attributes_list_fallback)
        (Fw32_display_monitor_attributes_list): New functions.
        (syms_of_w32fns): Defsubr Sw32_display_monitor_attributes_list.

        * w32term.c (SM_CXVIRTUALSCREEN, SM_CYVIRTUALSCREEN): Define macros
        if not defined.
        (x_display_pixel_height, x_display_pixel_width): Use GetSystemMetrics.

2013-07-04  Michael Albinus  <michael.albinus@gmx.de>

        * fileio.c (Qfile_notify_error): New error symbol.

        * gfilenotify.c (Fgfile_add_watch, Fgfile_rm_watch):
        * inotify.c (inotify_callback, symbol_to_inotifymask)
        (Finotify_add_watch, Finotify_rm_watch): Use it.
        (inotifyevent_to_event): Exchange order of cookie and file name.
        (Finotify_add_watch): Adapt docstring.

        * lisp.h (Qfile_notify_error): Declare.

2013-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        Try again to fix FreeBSD bug re multithreaded memory alloc (Bug#14569).
        * emacs.c (main) [HAVE_PTHREAD && !SYSTEM_MALLOC && !DOUG_LEA_MALLOC]:
        Do not clear _malloc_thread_enabled_p, undoing the previous change,
        which did not work (see <http://bugs.gnu.org/14569#307>).
        (main): Do not invoke malloc_enable_thread if (! CANNOT_DUMP
        && (!noninteractive || initialized)).  This attempts to thread
        the needle between the Scylla of FreeBSD and the Charybdis of Cygwin.

2013-07-04  Juanma Barranquero  <lekktu@gmail.com>

        * image.c (x_to_xcolors) [HAVE_NTGUI]: Remove unused var `hdc'.
        (x_build_heuristic_mask) [HAVE_NTGUI]: Remove unused var `frame_dc'.

2013-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        Try to fix FreeBSD bug re multithreaded memory allocation (Bug#14569).
        * emacs.c (main) [HAVE_PTHREAD && !SYSTEM_MALLOC && !DOUG_LEA_MALLOC]:
        Clear _malloc_thread_enabled_p at startup.  Reported by Ashish SHUKLA in
        <http://lists.gnu.org/archive/html/emacs-devel/2013-07/msg00088.html>.

2013-07-02  Paul Eggert  <eggert@cs.ucla.edu>

        * sysdep.c (sys_siglist) [HAVE_DECL___SYS_SIGLIST]:
        Define to __sys_siglist.

2013-07-02  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (IT_OVERFLOW_NEWLINE_INTO_FRINGE): Don't disallow
        word-wrap, so that overflow-newline-into-fringe would work in
        visual-line-mode.  (Bug#2749)
        (move_it_in_display_line_to): When the last scanned display
        element fits exactly on the display line, and
        overflow-newline-into-fringe is non-nil, but wrap_it is valid,
        don't return MOVE_NEWLINE_OR_CR, but instead back up to the last
        wrap point and return MOVE_LINE_CONTINUED.  Fixes problems with
        finding buffer position that corresponds to pixel coordinates,
        e.g. in buffer_posn_from_coords.

2013-07-02  Jan Djärv  <jan.h.d@swipnet.se>

        * process.c (handle_child_signal): Call catch_child_signal if
        NS_IMPL_GNUSTEP.

2013-07-02  Paul Eggert  <eggert@cs.ucla.edu>

        Don't convert function pointers to void * and back.
        It isn't portable C, and it's easy enough to avoid.
        * alloc.c: Verify SAVE_FUNCPOINTER bits, too.
        (make_save_value): Add support for SAVE_FUNCPOINTER.
        * keymap.c (map_keymap_char_table_item, map_keymap_internal):
        * print.c (print_object):
        Distinguish function from object pointers.
        * lisp.h (SAVE_FUNCPOINTER): New constant.
        (SAVE_SLOT_BITS): Adjust to it.
        (SAVE_TYPE_FUNCPTR_PTR_OBJ): New constant, replacing
        SAVE_TYPE_PTR_PTR_OBJ.  Change the only use.
        (voidfuncptr): New typedef.
        (struct Lisp_Save_Value): New member data[0].funcpointer.
        (XSAVE_FUNCPOINTER): New function.

        Simplify buildobj processing.
        * Makefile.in (buildobj.h): Make it a sequence of strings each
        followed by comma, rather than a single string.  Put it into a
        .tmp file in case there's an error while generating it.
        (gl-stamp): Use .tmp for temp files.
        (mostlyclean): Clean .tmp files.
        * doc.c (buildobj): Move to just the routine that needs it.
        It's now an array of strings, so processing is simpler.

2013-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        Fix bug re noninteractive multithreaded memory allocation (Bug#14569).
        * emacs.c (malloc_enable_thread): Hoist extern decl to top level.
        (main) [HAVE_PTHREAD && !SYSTEM_MALLOC && !DOUG_LEA_MALLOC]:
        Invoke malloc_enable_thread even when not interactive.
        Problem reported by Ken Brown in <http://bugs.gnu.org/14569#275>.
        * process.c (init_process_emacs) [CYGWIN]: Tickle glib even
        in this case, since the underlying bug has now been fixed.

2013-07-01  Juanma Barranquero  <lekktu@gmail.com>

        * emacs.c (Fkill_emacs): Expand Vauto_save_list_file_name before
        unlinking it (bug#14691).

2013-06-30  Michal Nazarewicz  <mina86@mina86.com>

        * buffer.c (FKill_buffer): Run `kill-buffer-query-functions'
        before checking whether buffer is modified.  This lets
        `kill-buffer-query-functions' cancel killing of the buffer or save
        its content before `kill-buffer' asks user the "Buffer %s
        modified; kill anyway?" question.

2013-06-30  Jan Djärv  <jan.h.d@swipnet.se>

        * nsfns.m (handlePanelKeys): Don't process Command+Function keys.
        Let the super performKeyEquivalent deal with them (Bug#14747).

2013-06-30  Paul Eggert  <eggert@cs.ucla.edu>

        * widget.c (resize_cb): Remove unused local.

        Do not use GTK 3 if it exists but cannot be compiled.
        * xmenu.c (x_menu_wait_for_event) [!USE_GTK]:
        * xterm.c (x_error_handler) [!USE_GTK]:
        Do not use GTK 3.

        * intervals.c (get_local_map): Actually clip POSITION (Bug#14753).

2013-06-30  Eli Zaretskii  <eliz@gnu.org>

        * intervals.c (get_local_map): Instead of aborting, clip POSITION
        to the valid range of values.  (Bug#14753)

        * xdisp.c (Fmove_point_visually): Invalidate the cursor position
        when moving point by using the current glyph matrix.  This avoids
        the need to force redisplay when this function is called in a
        loop.

2013-06-29  Paul Eggert  <eggert@cs.ucla.edu>

        Fix minor problems found by static checking.
        * coding.c (encode_inhibit_flag, inhibit_flag): New functions.
        Redo the latter's body to sidestep GCC parenthesization warnings.
        (setup_coding_system, detect_coding, detect_coding_system): Use them.
        * coding.c (detect_coding, detect_coding_system):
        * coding.h (struct undecided_spec):
        Use bool for boolean.
        * image.c (QCmax_width, QCmax_height): Now static.
        * xdisp.c (Fmove_point_visually): Remove unused local.

2013-06-29  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (Fmove_point_visually): New function.

2013-06-28  Kenichi Handa  <handa@gnu.org>

        * coding.h (define_coding_undecided_arg_index): New enum.
        (coding_attr_index): New members
        coding_attr_undecided_inhibit_null_byte_detection,
        coding_attr_undecided_inhibit_iso_escape_detection,
        coding_attr_undecided_prefer_utf_8.
        (undecided_spec): New struct.
        (struct coding_system): New member `undecided' of the member
        `spec'.

        * coding.c (setup_coding_system): Handle CODING->spec.undecided.
        (detect_coding): Likewise.
        (detect_coding_system): Likewise.
        (Fdefine_coding_system_internal): New coding system properties
        :inhibit-null-byte-detection, :inhibit-iso-escape-detection, and
        :prefer-utf-8.
        (syms_of_coding): Adjust for coding_arg_undecided_max.

2013-06-28  Paul Eggert  <eggert@cs.ucla.edu>

        * image.c (x_from_xcolors): Remove unused local.

2013-06-28  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>

        Defer image data transfer between X client and server until actual
        display happens.

        * dispextern.h (struct image) [HAVE_X_WINDOWS]: New members `ximg'
        and `mask_img'.

        * image.c (Destroy_Image): Remove.
        (x_clear_image_1): New arg `flags' instead of 3 bools `pixmap_p',
        `mask_p', and `colors_p'.  All uses changed.
        (x_clear_image_1) [HAVE_X_WINDOWS]: Destroy `ximg' and `mask_img'.
        (CLEAR_IMAGE_PIXMAP, CLEAR_IMAGE_MASK, CLEAR_IMAGE_COLORS):
        New macros for `flags' arg to x_clear_image_1.
        (postprocess_image, xpm_load_image, x_build_heuristic_mask)
        (png_load_body): Use x_clear_image_1 instead of Free_Pixmap.
        (ZPixmap, XGetImage) [HAVE_NS]: Remove.
        (image_get_x_image_or_dc, image_unget_x_image_or_dc)
        (image_get_x_image, image_unget_x_image): New functions or macros.
        (image_background, image_background_transparent, x_to_xcolors)
        (x_build_heuristic_mask): Use image_get_x_image_or_dc instead of
        XGetImage or CreateCompatibleDC.  Use image_unget_x_image_or_dc
        instead of Destroy_Image.
        (image_create_x_image_and_pixmap, image_put_x_image): New functions.
        (xpm_load_image, x_from_xcolors, x_build_heuristic_mask, pbm_load)
        (png_load_body, jpeg_load_body, tiff_load, gif_load)
        (imagemagick_load_image, svg_load_image): Use them instead of
        x_create_x_image_and_pixmap, and x_put_x_image followed by
        x_destroy_x_image, respectively.
        (xpm_load) [HAVE_XPM && !HAVE_NTGUI]: Use XpmReadFileToImage and
        XpmCreateImageFromBuffer instead of XpmReadFileToPixmap and
        XpmCreatePixmapFromBuffer.  Create pixmaps.  Fill background and
        background_transparent fields.
        (image_sync_to_pixmaps) [HAVE_X_WINDOWS]: New function.
        (prepare_image_for_display, x_disable_image) [HAVE_X_WINDOWS]: Use it.

2013-06-27  Paul Eggert  <eggert@cs.ucla.edu>

        Do not tickle glib SIGCHLD handling if Cygwin (Bug#14569).
        This mostly consists of undoing recent changes.
        * callproc.c (Fcall_process):
        * process.c (create_process):
        Do not worry about catching SIGCHLD here, undoing previous change.
        * nsterm.m (ns_term_init): Re-catch SIGCHLD, undoing previous change.
        * process.c, process.h (catch_child_signal):
        No longer extern if !NS_IMPL_GNUSTEP, undoing 06-22 change.
        * process.c (catch_child_handler): Don't worry about being called
        lazily and do not assume caller has blocked SIGCHLD, undoing
        previous change.  Move first-time stuff back to
        init_process_emacs, undoing 06-22 change.  If CYGWIN, do not
        tickle glib, as that causes Cygwin bootstrap to fail.  Do not
        set lib_child_handler if it's already initialized, which may
        help avoid problems on GNUStep.

2013-06-23  Paul Eggert  <eggert@cs.ucla.edu>

        A more-conservative workaround for Cygwin SIGCHLD issues (Bug#14569).
        * callproc.c (Fcall_process):
        * process.c (create_process):
        Make sure SIGCHLD is caught before we fork,
        since Emacs startup no arranges to catch SIGCHLD.
        * process.c (lib_child_handler): Initialize to null, not to
        dummy_handler.
        (catch_child_signal): Allow self to be called lazily.
        Do nothing if it's already been called.
        Assume caller has blocked SIGCHLD (all callers do now).
        * emacs.c (main): Do not catch SIGCHLD here; defer it until
        just before it's really needed.
        * nsterm.m (ns_term_init): No need to re-catch SIGCHLD here,
        since it hasn't been caught yet.

2013-06-23  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * image.c (compute_image_size): New function to implement
        :max-width and :max-height.
        (imagemagick_load_image): Use it.

2013-06-23  Paul Eggert  <eggert@cs.ucla.edu>

        Try to avoid malloc SEGVs on Cygwin (Bug#14569).
        * callproc.c, process.h (block_child_signal, unblock_child_signal):
        Now extern.
        * emacs.c (main): Catch SIGCHLD just before initializing gfilenotify.
        * process.c (catch_child_signal): Block SIGCHLD while futzing with
        the SIGCHLD handler, since the code is not atomic and (due to glib)
        signals may be arriving now.
        * sysdep.c (init_signals): Do not catch child signals here;
        'main' now does that later, at a safer time.

2013-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        Clean up SIGCHLD handling a bit (Bug#14569).
        * process.c, process.h (catch_child_signal):
        Now always extern, even if !NS_IMPL_GNUSTEP.
        * process.c (catch_child_signal): Move glib tickler here from
        init_process_emacs, so that it's done earlier in Emacs
        initialization.  Also move the noninteractive && !initialized
        check here from init_process_emacs.  This is all a bit cleaner for
        GNUish platforms, and I hope it works around the Cygwin bug.
        * sysdep.c (init_signals): Invoke catch_child_signal here, so
        that glib signal handling is tickled before glib creates threads.

        * process.c (wait_reading_process_output): Avoid int overflow
        when reading more than 2 GiB total from a process.

2013-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        * process.c (create_process): Handle a couple more cases,
        i.e., work even if new_argv and wait_child_setup[i] are cached.
        Use Fcall_process's style for volatile vars.

2013-06-21  Andreas Schwab  <schwab@linux-m68k.org>

        * process.c (create_process): Mark PROCESS volatile.

2013-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        Use C99-style flexible array members if available.
        This avoids some subtle aliasing issues, which typically
        aren't a problem with GCC but may be a problem elsewhere.
        * alloc.c (sdata): New typedef, replacing the old struct sdata.
        It is a struct if GC_CHECK_STRING_BYTES, a union otherwise.
        In either case, it uses a flexible array member rather than
        the old struct hack.  All uses changed.
        (SDATA_NBYTES, sweep_strings) [!GC_CHECK_STRING_BYTES]:
        Adjust to sdata reorganization.
        * alloc.c (VBLOCK_BYTES_MIN, allocate_vectorlike, Fgarbage_collect):
        Use offsetof (struct, flex_array_member), not sizeof (struct), as
        that ports better to pre-C99 non-GCC.
        * chartab.c (Fmake_char_table, make_sub_char_table, copy_char_table):
        Use CHAR_TABLE_STANDARD_SLOTS rather than its definition,
        as the latter has changed.
        * conf_post.h (FLEXIBLE_ARRAY_MEMBER): Move here from w32.c,
        and port better to pre-C99 GCC.
        * image.c (struct xpm_cached_color):
        * lisp.h (struct Lisp_Vector, struct Lisp_Bool_Vector)
        (struct Lisp_Char_Table, struct Lisp_Sub_Char_Table):
        Use FLEXIBLE_ARRAY_MEMBER.
        * lisp.h (string_bytes) [GC_CHECK_STRING_BYTES]:
        Move decl to top level so it gets checked against implementation.
        (CHAR_TABLE_STANDARD_SLOTS): Adjust to struct Lisp_Char_Table change.
        * w32.c (FLEXIBLE_ARRAY_MEMBER): Move to conf_post.h.

2013-06-20  Paul Eggert  <eggert@cs.ucla.edu>

        * syntax.c: Integer cleanups.
        (SYNTAX_FLAGS_COMMENT_STYLEC): Return a boolean, not 0-or-2.
        All uses that need 0-or-2 changed to:
        (SYNTAX_FLAGS_COMMENT_STYLEC2): New macro, with the same semantics
        as the old SYNTAX_FLAGS_COMMENT_STYLEC.
        (struct lisp_parse_state, syntax_prefix_flag_p, update_syntax_table)
        (char_quoted, prev_char_comend_first, back_comment)
        (Finternal_describe_syntax_value, skip_chars, skip_syntaxes)
        (in_classes, forw_comment, scan_lists, scan_sexps_forward):
        Use bool for boolean.
        (update_syntax_table, skip_chars, skip_syntaxes):
        Prefer int to unsigned when either will do.
        (back_comment): Return boolean success flag, like forw_comment,
        instead of positive-or-minus-1 (which might have overflowed int anyway).
        Don't stuff ptrdiff_t into int.
        (syntax_spec_code, syntax_code_spec): Now const.
        (Fmatching_paren, scan_lists, scan_sexps_forward):
        Use enum syntaxcode for syntax code.
        (Fmatching_paren): Check that arg is a character, not just an integer.
        (Fstring_to_syntax): Don't assume 0377 fits in enum syntaxcode.
        (Finternal_describe_syntax_value): Omit no-longer-needed
        comparison to 0.
        (skip_chars): Use char, not unsigned char, when the distinction
        doesn't matter.
        (forw_comment, scan_lists): Prefer A |= B to A = A || B when B's cheap.
        * bytecode.c (exec_byte_code):
        * syntax.c (syntax_spec_code, Fchar_syntax)
        (Finternal_describe_syntax_value, skip_chars, skip_syntaxes)
        (init_syntax_once):
        * syntax.h (SYNTAX_WITH_FLAGS):
        Omit unnecessary casts.

2013-06-20  Eli Zaretskii  <eliz@gnu.org>

        * w32fns.c (w32_wnd_proc): Don't compute the header line and mode
        line dimensions here, to avoid race conditions with the main
        thread.  (Bug#14062, bug#14630, bug#14669)

        * w32term.c (w32_draw_window_cursor): Compute the header line and
        mode line dimensions here.
        <w32_system_caret_window, w32_system_caret_hdr_height>:
        <w32_system_caret_mode_height>: New variables.

        * w32term.h: Declare them.

2013-06-20  Paul Eggert  <eggert@cs.ucla.edu>

        * alloc.c (die): Move "assertion failed" string here ...
        * lisp.h (eassert): ... from here.  Also, suppress evaluation of
        COND when SUPPRESS_CHECKING.  This shrinks the executable text
        size by 0.8% to 2.2% when configured with --enable-checking,
        depending on optimization flags (GCC 4.8.1 x86-64).

        * floatfns.c (Flog10): Move to Lisp (marked obsolete there).

2013-06-20  Rüdiger Sonderfeld <ruediger@c-plusplus.de>

        * floatfns.c (Flog) [HAVE_LOG2]: Use log2 if available and if the
        base is 2; this is more accurate.

2013-06-19  Juanma Barranquero  <lekktu@gmail.com>

        * sound.c (string_default): Move to !WINDOWSNT section.
        (Fplay_sound_internal) [WINDOWSNT]: Remove i_result to avoid warning.

2013-06-19  Paul Eggert  <eggert@cs.ucla.edu>

        * sound.c: Integer cleanups.
        Remove unnecessary forward decls.
        (struct sound_device): The 'file' member is now a Lisp_Object, not
        a char *, so that we needn't invoke alloca on a huge size.
        (Fplay_sound_internal): Adjust to this.
        (string_default): New function.
        (vox_open, vox_init, alsa_open, alsa_configure, alsa_init):
        Use it to adjust to the struct sound_device change.
        (parse_sound, wav_init, au_init, alsa_init): Use bool for booleans.
        (be2hs) [0]: Remove.

        * syntax.c (skip_chars): Don't use uninitialized storage
        when searching a multibyte buffer for characters that are not in a
        unibyte string that contains non-ASCII characters.

2013-06-18  Jan Djärv  <jan.h.d@swipnet.se>

        * process.c: Include xgselect.h if HAVE_GLIB.  Include glib.h
        if HAVE_GLIB && ! WINDOWSNT (Bug#14654).

2013-06-18  Paul Eggert  <eggert@cs.ucla.edu>

        * conf_post.h: Add comments for INLINE, EXTERN_INLINE, etc.

2013-06-18  Kenichi Handa  <handa@gnu.org>

        * font.c (Ffont_spec): Signal an error for an invalid font name
        (Bug#14648).

2013-06-18  Paul Eggert  <eggert@cs.ucla.edu>

        Porting fixes for merged specpdl and backtrace stacks (Bug#14643).
        In particular this ports to 32-bit sparc Sun cc.
        * eval.c (init_eval_once, grow_specpdl): Allocate a specbinding
        array with a dummy element at specpdl[-1], so that its address can
        be taken portably.
        (unbind_to): Do not copy the binding; not needed, now that we
        copy old_value in the one place where the copy is needed.
        * fileio.c (Fwrite_region): Use ptrdiff_t, not int, for specpdl count.
        * lisp.h (BITS_PER_PTRDIFF_T): Remove; no longer needed.
        (union specbinding): Rename from struct specbinding.  Redo layout
        to avoid the need for 'ptrdiff_t nargs : BITS_PER_PTRDIFF_T - 1;',
        which is not portable.  With Sun C 5.12 32-bit sparc, the
        declaration causes nargs to be an unsigned bitfield, a behavior
        that the C standard allows; but Emacs wants nargs to be signed.
        The overall type is now a union of structures rather than a
        structure of union of structures, and the 'kind' member is now a
        bitfield, so that the overall type doesn't grow.  All uses changed.
        * process.c (Fmake_serial_process): Remove unnecessary initialization.

2013-06-17  Paul Eggert  <eggert@cs.ucla.edu>

        * frame.c (x_report_frame_params): Cast parent_desc to uintptr_t.
        Needed if HAVE_NTGUI.  Reported by Juanma Barranquero.

        * nsfont.m (ns_registry_to_script): Parenthesize while expression.

2013-06-17  Eli Zaretskii  <eliz@gnu.org>

        * w32fns.c (w32_wnd_proc): Don't call WINDOW_HEADER_LINE_HEIGHT
        unless we know that the window w's frame is a frame object.
        Another attempt at solving bug#14062 and bug#14630.

2013-06-17  Lars Magne Ingebrigtsen  <larsi@gnus.org>

        * textprop.c (property_set_type): New enum.
        (add_properties): Allow appending/prepending text properties.
        (add_text_properties_1): Factored out of Fadd_text_properties.
        (Fadd_text_properties): Move all the code into
        add_text_properties_1.
        (Fadd_face_text_property): New function that calls
        add_text_properties_1.

2013-06-17  Paul Eggert  <eggert@cs.ucla.edu>

        Move functions from lisp.h to individual modules when possible.
        From a suggestion by Andreas Schwab in <http://bugs.gnu.org/11935#68>.
        * alloc.c (XFLOAT_INIT, set_symbol_name):
        * buffer.c (CHECK_OVERLAY):
        * chartab.c (CHECK_CHAR_TABLE, set_char_table_ascii)
        (set_char_table_parent):
        * coding.c (CHECK_NATNUM_CAR, CHECK_NATNUM_CDR):
        * data.c (BOOLFWDP, INTFWDP, KBOARD_OBJFWDP, OBJFWDP, XBOOLFWD)
        (XKBOARD_OBJFWD, XINTFWD, XOBJFWD, CHECK_SUBR, set_blv_found)
        (blv_value, set_blv_value, set_blv_where, set_blv_defcell)
        (set_blv_valcell):
        * emacs.c (setlocale) [!HAVE_SETLOCALE]:
        * eval.c (specpdl_symbol, specpdl_old_value, specpdl_where)
        (specpdl_arg, specpdl_func, backtrace_function, backtrace_nargs)
        (backtrace_args, backtrace_debug_on_exit):
        * floatfns.c (CHECK_FLOAT):
        * fns.c (CHECK_HASH_TABLE, CHECK_LIST_END)
        (set_hash_key_and_value, set_hash_next, set_hash_next_slot)
        (set_hash_hash, set_hash_hash_slot, set_hash_index)
        (set_hash_index_slot):
        * keymap.c (CHECK_VECTOR_OR_CHAR_TABLE):
        * marker.c (CHECK_MARKER):
        * textprop.c (CHECK_STRING_OR_BUFFER):
        * window.c (CHECK_WINDOW_CONFIGURATION):
        Move here from lisp.h, and make these functions static rather than
        extern inline.
        * buffer.c (Qoverlayp):
        * data.c (Qsubrp):
        * fns.c (Qhash_table_p):
        * window.c (Qwindow_configuration_p):
        Now static.
        * lisp.h: Remove the abovementioned defns and decls.

        Use functions, not macros, for XINT etc. (Bug#11935).
        In lisp.h, prefer functions to function-like macros, and
        constants to object-like macros, when either will do.  This:
         . simplifies use, as there's no more need to worry about
           arguments' side effects being evaluated multiple times.
         . makes the code easier to debug on some platforms.
        However, when using gcc -O0, keep using function-like macros
        for a few critical operations, for performance reasons.
        This sort of thing isn't needed with gcc -Og, but -Og
        is a GCC 4.8 feature and isn't widely-enough available yet.
        * alloc.c (gdb_make_enums_visible) [USE_LSB_TAG]:
        Remove enum lsb_bits; no longer needed.
        (allocate_misc, free_misc): Don't use XMISCTYPE as an lvalue.
        * buffer.c (Qoverlap):
        * data.c (Qsubrp):
        * fns.c (Qhash_table_p):
        Now extern, so lisp.h can use these symbols.
        * dispextern.h: Include character.h, for MAX_CHAR etc.
        (GLYPH, GLYPH_CHAR, GLYPH_FACE, SET_GLYPH_CHAR, SET_GLYPH_FACE)
        (SET_GLYPH, GLYPH_CODE_CHAR, GLYPH_CODE_FACE)
        (SET_GLYPH_FROM_GLYPH_CODE, GLYPH_MODE_LINE_FACE, GLYPH_CHAR_VALID_P)
        (GLYPH_CODE_P): Move here from lisp.h.
        (GLYPH_CHAR, GLYPH_FACE, GLYPH_CODE_CHAR, GLYPH_CODE_FACE)
        (GLYPH_CHAR_VALID_P, GLYPH_CODE_P): Now functions, not macros.
        (GLYPH_MODE_LINE_FACE): Now enums, not macros.
        * eval.c (Fautoload): Cast XUNTAG output to intptr_t, since
        XUNTAG now returns void *.
        * lisp.h (lisp_h_XLI, lisp_h_XIL, lisp_h_CHECK_LIST_CONS)
        (lisp_h_CHECK_NUMBER CHECK_SYMBOL, lisp_h_CHECK_TYPE)

        (lisp_h_XPNTR, lisp_h_XSYMBOL):
        New macros, renamed from their sans-lisp_h_ counterparts.
        (XLI, XIL, CHECK_LIST_CONS, CHECK_NUMBER CHECK_SYMBOL)
        (CHECK_TYPE, CONSP, EQ, FLOATP, INTEGERP, MARKERP)

        (VECTORLIKEP, XCAR, XCDR, XCONS, XHASH, XPNTR, XSYMBOL):
        If compiling via GCC without optimization, define these as macros
        in addition to inline functions.
        To disable this, compile with -DINLINING=0.
        (LISP_MACRO_DEFUN, LISP_MACRO_DEFUN_VOID): New macros.
        (check_cons_list) [!GC_CHECK_CONS_LIST]: Likewise.
        (make_number, XFASTINT, XINT, XTYPE, XUNTAG): Likewise, but
        hand-optimize only in the USE_LSB_TAG case, as GNUish hosts do that.
        (INTMASK, VALMASK): Now macros, since static values cannot be
        accessed from extern inline functions.
        (VALMASK): Also a constant, for benefit of old GDB.
        (LISP_INT_TAG_P): Remove; no longer needed as the only caller
        is INTEGERP, which can fold it in.
        (XLI, XIL, XHASH, XTYPE, XINT, XFASTINT, XUINT)
        (make_number, XPNTR, XUNTAG, EQ, XCONS, XVECTOR, XSTRING, XSYMBOL)

        Now functions.
        (check_cons_list) [!GC_CHECK_CONS_LIST]: New empty function.
        (LISP_MAKE_RVALUE, TYPEMASK): Remove; no longer needed.
        (VALMASK): Define in one place rather than in two, merging the
        USE_LSB_TAG parts; this is simpler.
        (aref_addr, gc_aset, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM)
        (max, min, struct Lisp_String, UNSIGNED_CMP, ASCII_CHAR_P):
        Move up, to avoid use before definition.
        Also include "globals.h" earlier, for the same reason.
        (make_natnum): New function.
        (XUNTAG): Now returns void *, not intptr_t, as this means fewer casts.
        (union Lisp_Fwd, BOOLFWDP, BOOL_VECTOR_P, BUFFER_OBJFWDP, BUFFERP)
        (CHAR_TABLE_P, CHAR_TABLE_REF_ASCII, CONSP, FLOATP, INTEGERP, INTFWDP)

        (STRING_COPYIN): Remove; unused.
        (XCAR_AS_LVALUE, XCDR_AS_LVALUE): Remove these macros, replacing with ...
        (xcar_addr, xcdr_addr): New functions.  All uses changed.

        (functionp): Return bool, not int.
        * window.c (Qwindow_configuration_p): Now extern,

2013-06-15  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (Fline_pixel_height): New function, required for solving
        bug #14567.

2013-06-11  Paul Eggert  <eggert@cs.ucla.edu>

        Tickle glib by waiting for Emacs itself, not for process 0 (Bug#14569).
        * process.c (init_process_emacs) [HAVE_GLIB && !WINDOWSNT]:
        Wait for self, not for 0.  This can't hurt on GNU or similar
        system, and may help with Cygwin.

        * keyboard.c: Don't use PROP (...) as an lvalue.
        (parse_tool_bar_item) [!USE_GTK && !HAVE_NS]:
        Use set_prop (A, B), not PROP (A) = B.

2013-06-10  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (get_it_property): Use it->window instead of generating
        a Lisp object from it->w.

2013-06-09  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (get_it_property): If it->object is a buffer, pass to
        get-char-property the window that is being rendered, instead of
        the buffer, to support window-specific overlays.  (Bug#14575)
        (compute_display_string_pos): When W is NULL, use the current
        buffer as the object to pass to get-char-property.
        (Fcurrent_bidi_paragraph_direction): Assign NULL to the window
        pointer member of the bidi iterator, since no window is pertinent
        to this function.

2013-06-08  Eli Zaretskii  <eliz@gnu.org>

        * bidi.c (bidi_fetch_char): Accept additional argument, the window
        being displayed, and pass it to compute_display_string_pos.
        (bidi_level_of_next_char, bidi_resolve_explicit_1)
        (bidi_paragraph_init): All callers changed.

        displayed.
        (compute_display_string_pos): Adjust prototype.

2013-06-08  Jan Djärv  <jan.h.d@swipnet.se>

        * xgselect.c: Remove unneeded include xterm.h.

        * process.c (wait_reading_process_output): Check for NS before GLIB.
        GLIB may be linked in due to rsvg, but ns_select must be called.

        * xgselect.c (xg_select): Remove call to window_system_available
        and g_main_context_pending at the top, so Gdk events (i.e. file
        notify) are processed when Emacs is started with -nw.

2013-06-07  Eli Zaretskii  <eliz@gnu.org>

        * Makefile.in (ctagsfiles1, ctagsfiles2): Don't include *.m files.
        (ctagsfiles3): New variable, includes only *.m files.
        (TAGS): Use an explicit language name in the regular expressions,
        to avoid transformation of '/SOMETHING' by MSYS to
        'c:\MSYS\SOMETHING'.

2013-06-07  Richard Copley  <rcopley@gmail.com>  (tiny change)

        * epaths.in: Fix commentary to PATH_SITELOADSEARCH.

2013-06-06  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (note_mouse_highlight): When mouse-highlight is off,
        still need to set the mouse pointer shape and activate help-echo.
        (Bug#14558)

2013-06-06  Paul Eggert  <eggert@cs.ucla.edu>

        A few porting etc. fixes for the new file monitor code.
        See the thread containing
        <http://lists.gnu.org/archive/html/emacs-devel/2013-06/msg00109.html>.
        * gfilenotify.c (dir_monitor_callback, Fgfile_add_watch)
        (Fgfile_rm_watch): Don't assume EMACS_INT is the same width as a pointer.
        (dir_monitor_callback, Fgfile_rm_watch):
        Use assq_no_quit instead of Fassoc, for speed.
        (dir_monitor_callback, Fgfile_rm_watch):
        eassert that the monitor is a fixnum.
        (dir_monitor_callback): No need for CDR_SAFE.
        Simplify building of lisp with alternative tails.
        (Fgfile_add_watch, Fgfile_rm_watch):
        Do not assume glib functions set errno reliably on failure.
        (Fgfile_add_watch): Check that the monitor survives the XIL trick,
        and signal an error otherwise.
        (Fgfile_rm_watch): Prefer CONSP to !NILP.
        Use Fdelq instead of Fdelete, for speed.

2013-06-05  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (handle_tool_bar_click): When mouse-highlight is off,
        don't insist on being invoked on a highlighted tool-bar button.
        Avoids losing tool-bar functionality when mouse-highlight is nil.
        (note_tool_bar_highlight, note_mode_line_or_margin_highlight):
        Don't highlight when mouse-highlight is nil.
        (note_mouse_highlight): When mouse-highlight is nil, don't return

        referring to insert_1, which no longer exists.

        * xdisp.c (message_dolog): If the *Messages* buffer is shown in
        some window, increment windows_or_buffers_changed, so that
        *Messages* display in that window is updated.  (Bug#14408)

        * w32.c: Include epaths.h.
        (init_environment): Use cmdproxy.exe without leading directories.

        * xterm.h (GTK_PREREQ): New macro.
        All simple uses of GTK_MAJOR_VERSION and GTK_MINOR_VERSION changed
        to use this macro instead, for consistency and clarity.

2013-05-08  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (row_for_charpos_p): New function, with code of
        cursor_row_p, but accepts an additional argument CHARPOS instead
        of using a hardcoded PT.
        (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
        (row_containing_pos): Call row_for_charpos_p instead of partially

        when longlines-show-effect includes more than one newline, when
        moving the cursor vertically up.

2013-05-08  Juanma Barranquero  <lekktu@gmail.com>

        * makefile.w32-in (ACL_H): New macro.

        !acl_errno_valid.
        (Fcopy_file) [!WINDOWSNT]: Use qcopy_acl instead of rolling
        it ourselves.

        * unexelf.c: Don't assume ElfW (Half) fits in int.
        (entry_address, find_section, unexec): Use ptrdiff_t, not int,
        when dealing with ElfW (Half) values, since they can exceed 2**31
        on 64-bit OpenBSD hosts.  Problem reported privately by Han Boetes.
        (entry_address): Omit unused NUM arg.  All uses changed.

2013-05-07  Juri Linkov  <juri@jurta.org>

        * callint.c (Fcall_interactively): Set `visargs[i]' for code 'n'
        to the string converted from number with `Fnumber_to_string'.

        * xfns.c (x_get_net_workarea, struct MonitorInfo, free_monitors)
        (x_get_monitor_for_frame, x_make_monitor_attribute_list)
        (x_get_monitor_attributes_fallback)

2013-05-07  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>
            Jan Djärv  <jan.h.d@swipnet.se>

        * Makefile.in (XRANDR_LIBS, XRANDR_CFLAGS, XINERAMA_LIBS)
        (XINERAMA_CFLAGS): New macros.
        (ALL_CFLAGS, LIBES): Use them.

        * xfns.c: Include <X11/extensions/Xrandr.h> if HAVE_XRANDR, and
        include <X11/extensions/Xinerama.h> if HAVE_XINERAMA.
        (Qgeometry, Qworkarea, Qmm_size, Qframes, Qsource): New variables.
        (syms_of_xfns): DEFSYM them.
        (struct MonitorInfo): New struct.
        (x_get_net_workarea, free_monitors, x_get_monitor_for_frame)
        (x_make_monitor_attribute_list, x_get_monitor_attributes_fallback)

        and dpyinfo->Xatom_net_current_desktop.

2013-05-06  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (pos_visible_p): Use the special code for finding the
        beginning of a display property or overlay for any "replacing"
        display property, not just for display strings.  This solves
        incorrect reporting of position by posn-at-point.  (Bug#14241)

2013-05-06  Paul Eggert  <eggert@cs.ucla.edu>

        * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
        Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
        Verify that ElfW (Half) fits in int.
        (fatal): Use same signature as lisp.h.
        (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
        configure and build with -DUNEXELF_DEBUG without worrying about
        other modules that use DEBUG.
        (DEBUG_LOG) [UNEXELF_DEBUG]: New macro.  All debug code that prints
        possibly-wide integers now uses it instead of plain fprintf.
        (entry_address): New function, which avoids problems with 32-bit
        overflow on 64-bit hosts.
        (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
        (round_up): Don't assume the remainder fits in int.
        (find_section): Use bool for boolean.  Simplify debug code.
        (unexec): Don't assume file sizes fit in int or size_t.
        Omit unnecessary trailing newline in 'fatal' format.
        Use strerror rather than outputting decimal error number.
        Remove unused code when emacs is not defined;
        this file relies on Emacs now.
        Don't assume e_phnum and e_shnum are positive.

        * regex.c: Fix problems when DEBUG is defined.
        (extract_number, extract_number_and_incr): Define regardless of
        whether DEBUG is defined; that's simpler and makes the code less
        likely to go stale in the normal case when DEBUG is not defined.
        Return int rather than taking an int * arg.  All callers changed.
        (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
        Remove, replacing with ...
        (DEBUG_PRINT): New macro.  All callers changed.
        (DEBUG_COMPILES_ARGUMENTS): New macro.
        (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
        (print_compiled_pattern, print_double_string) [DEBUG]:
        Use prototype rather than old-style definition.
        (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
        (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
        (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
        (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
        Don't assume ptrdiff_t, size_t, and long are the same width as int.
        (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
        This matters only when DEBUG is defined.

2013-05-05  Eli Zaretskii  <eliz@gnu.org>

        * xdisp.c (set_iterator_to_next): Set the
        ignore_overlay_strings_at_pos_p flag only if we are _really_
        iterating over an overlay string, as indicated by the
        current.overlay_string_index member.  (Bug#14306)

2013-05-05  Jan Djärv  <jan.h.d@swipnet.se>

        * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
        to where it is used, to avoid autorelease issues (Bug#14050).

2013-05-05  Paul Eggert  <eggert@cs.ucla.edu>

        `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
        * fileio.c (syms_of_fileio): Implement this.
        * filelock.c (create_lock_file): If symbolic links don't work, so
        we use a regular file as a lock file, do not fsync the lock file;
        it's not needed.

2013-05-04  Stefan Monnier  <monnier@iro.umontreal.ca>

        * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.
        (syms_of_minibuf): Adjust accodingly.
        * lread.c (Fread):
        * callint.c (Fcall_interactively): Adjust calls accordingly.

2013-05-04  Eli Zaretskii  <eliz@gnu.org>

        * dispextern.h (WINDOW_WANTS_HEADER_LINE_P): Verify that
        w->contents is a buffer before computing everything else.
        Use parentheses to disambiguate last part of the condition.

        * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
        assertion violations.  (Bug#14062)

2013-05-01  David Reitter  <david.reitter@gmail.com>

2013-04-28  Dan Nicolaescu  <dann@gnu.org>

        * dispextern.h (struct face): Move enum face_underline_type
        earlier so that bitfields can be in the same word.

2013-04-28  Jan Djärv  <jan.h.d@swipnet.se>

        * nsfns.m (handlePanelKeys): New function.
        (EmacsOpenPanel:performKeyEquivalent:)
        (EmacsSavePanel:performKeyEquivalent:): Call handlePanelKeys to handle
        arrows/function/control and copy/paste keys (Bug#14296).

2013-04-27  Juri Linkov  <juri@jurta.org>

        * callint.c (Fcall_interactively): Call `Qread_number' for
        interactive code letter `n' instead of using duplicate code.

2013-04-27  Paul Eggert  <eggert@cs.ucla.edu>

        * systime.h (make_timeval): Declare as 'const'.

        * font.c (font_open_entity): Always open a font of manageable
        size.

2013-04-26  Paul Eggert  <eggert@cs.ucla.edu>

        Port better to AIX (Bug#14258).
        * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
        to pacify AIX xlc.

2013-04-24  Kenichi Handa  <handa@gnu.org>

        * coding.c (decode_coding_iso_2022): When an invalid escape
        sequence is encountered, reset the invocation and designation
        status to the safest one.

2013-04-22  Paul Eggert  <eggert@cs.ucla.edu>

        * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
        Without this fix, "make distclean" leaves stamp-h1 behind.

2013-04-20  Erik Charlebois  <erikcharlebois@gmail.com>

        * w32fns.c (w32_fullscreen_rect): New function to compute the
        window rectangle for the given fullscreen mode.
        (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
        longer tunes the window size.  This keeps the window's edges flush
        with the screen and allows the taskbar to hide itself in fullboth.

        * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
        window decorations and uses the entire screen.

        * w32term.h  (w32_fullscreen_rect) Add prototype.
        (struct w32_output): Replace normal_width, normal_height,
        normal_top, and normal_left members with a single normal_placement
        struct.

        Remove macros.
        (FRAME_NORMAL_PLACEMENT): New macro.

        * w32fns.c (w32_wnd_proc): Add more assertions to investigate
        bug#14062.

        * frame.h (WINDOW_FRAME): Protect macro and its argument with
        parentheses.

        * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
        (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
        (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
        parentheses where appropriate.

2013-04-14  Eli Zaretskii  <eliz@gnu.org>

        * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
        <left-fringe-width, right-fringe-width, fringes-outside-margins>:
        Mention in the doc string that setting these variables takes
        effect only after a call to set-window-buffer.  (Bug#14200)

2013-04-13  Eli Zaretskii  <eliz@gnu.org>

        * indent.c (Fvertical_motion): Don't consider display strings on
        overlay strings as display strings on the buffer position we
        started from.  This prevents vertical cursor motion from jumping
        more than one line when there's an overlay string with a display
        property at end of line.
        Reported by Karl Chen <Karl.Chen@quarl.org> in
        http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

2013-04-12  Stefan Monnier  <monnier@iro.umontreal.ca>

        * window.c (select_window): `record_buffer' even if window is
        already selected (bug#14191).

2013-04-11  Eli Zaretskii  <eliz@gnu.org>

        * window.c (Fwindow_end): Test more flags, including the buffer's
        last_overlay_modified flag, to determine whether the window's
        display is really up-to-date.  Prevents the function from
        returning a stale value.  (Bug#14170)
        (Fwindow_line_height): Fix the test for up-to-date-ness of the
        current matrix.

2013-04-10  Eli Zaretskii  <eliz@gnu.org>

        * frame.c (do_switch_frame): Mark the TTY frame we switch to as
        garbaged only if it is not already the top frame on its TTY.
        This prevents flickering due to constant redrawing of TTY frames when
        there are GUI frames open in the same session.  (Bug#13864)

2013-04-10  Stefan Monnier  <monnier@iro.umontreal.ca>

        * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead

        This bug was introduced by my 2013-02-25 change that simplified

        Prefer < to > in range checks such as 0 <= i && i < N.
        This makes it easier to visualize quantities on a number line.
        This patch doesn't apply to all such range checks,
        only to the range checks affected by the 2013-03-24 change.

        Use contents slot, not buffer, where appropriate.
        * frame.c (set_menu_bar_lines_1): Use WINDOW_VERTICAL_COMBINATION_P
        and WINDOW_HORIZONTAL_COMBINATION_P.
        (make_frame_visible_1): Simplify the loop.
        Use contents slot, not buffer, where appropriate.
        * xdisp.c (hscroll_window_tree, mark_window_display_accurate)
        (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
        (expose_window_tree): Likewise.
        Use contents slot, not buffer, where appropriate.
        * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
        to avoid deleted windows.  Use contents slot instead of buffer.

        * frame.c (display_x_get_resource, Fx_get_resource): Break long line.

2013-03-24  Paul Eggert  <eggert@cs.ucla.edu>

        Static checking by GCC 4.8-20130319.
        * image.c (gif_load): Assume pass < 3 to pacify GCC.
        * process.c (Fset_process_datagram_address)
        (Fmake_network_process): Check get_lisp_to_sockaddr_size return value.
        * xdisp.c (get_char_face_and_encoding):
        (get_glyph_face_and_encoding): Ensure that *CHAR2B is initialized.
        (get_glyph_face_and_encoding): Prepare face before possibly using it.
        (get_per_char_metric): Don't use CHAR2B if it might not be initialized.

2013-03-24  Ken Brown  <kbrown@cornell.edu>

        * w32fns.c (emacs_abort) [CYGWIN]: Define `_open' as a macro to
        fix compilation on 64-bit Cygwin, where underscores are not
        automatically prepended.

        * w32term.c (w32_initialize): Silence compiler warning.

2013-03-23  Eli Zaretskii  <eliz@gnu.org>

        * w32term.c (w32fullscreen_hook): Use FRAME_NORMAL_WIDTH,
        FRAME_NORMAL_HEIGHT, and FRAME_PREV_FSMODE, instead of static
        variables, to save and restore frame dimensions.
        Use FRAME_NORMAL_LEFT and FRAME_NORMAL_TOP to restore frame position
        after returning from a 'fullscreen' configuration.
        use SendMessage instead of PostMessage to send the SC_RESTORE message,
        to avoid races between the main thread and the input thread.

        * w32term.h (struct w32_output): New members normal_width,
        normal_height, normal_top, normal_left, and prev_fsmode.
        (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP)
        (FRAME_NORMAL_LEFT, FRAME_PREV_FSMODE): New macros to access these
        members of a frame.

        * w32term.c (w32fullscreen_hook): Record last value of the frame's
        'fullscreen' parameter.  Always record previous width and height
        of the frame, except when switching out of maximized modes, so
        that they could be restored correctly, instead of resetting to the
        default frame dimensions.  Send SC_RESTORE command to the frame,
        unless we are going to send SC_MAXIMIZE, to restore the frame
        resize hints in the mouse pointer shown by the window manager.
        (Bug#14032)

        * frame.c (get_frame_param): Now extern for WINDOWSNT as well.

        declaration.

2013-03-22  Ken Brown  <kbrown@cornell.edu>

        (read_exe_header): Add magic numbers for x86_64.
        (fixup_executable): Fix printf format specifier for unsigned long
        argument.

2013-03-22  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.h (struct frame): Put menu_bar_window under #ifdef
        because this member is not needed when X toolkit is in use.
        (fset_menu_bar_window):
        * dispnew.c (clear_current_matrices, clear_desired_matrices)
        (free_glyphs, update_frame):
        * xdisp.c (expose_frame): Likewise.
        (display_menu_bar): Likewise.  Remove redundant eassert.
        * window.h (WINDOW_MENU_BAR_P): Always define to 0 if X
        toolkit is in use.

2013-03-21  Paul Eggert  <eggert@cs.ucla.edu>

        Use functions and constants to manipulate Lisp_Save_Value objects.
        This replaces code that used macros and strings and token-pasting.
        The change makes the C source a bit easier to follow,
        and shrinks the Emacs executable a bit.
        * alloc.c: Verify some properties of Lisp_Save_Value's representation.
        (make_save_value): Change 1st arg from string to enum.  All callers

        (XSAVE_OBJECT): Now functions, not macros.
        (STRING_BYTES_BOUND): Now just a macro, not a constant too;
        the constant was never used.
        (SAVE_SLOT_BITS, SAVE_VALUE_SLOTS, SAVE_TYPE_BITS, SAVE_TYPE_INT_INT)
        (SAVE_TYPE_INT_INT_INT, SAVE_TYPE_OBJ_OBJ, SAVE_TYPE_OBJ_OBJ_OBJ)
        (SAVE_TYPE_OBJ_OBJ_OBJ_OBJ, SAVE_TYPE_PTR_INT, SAVE_TYPE_PTR_OBJ)
        (SAVE_TYPE_PTR_PTR, SAVE_TYPE_PTR_PTR_OBJ, SAVE_TYPE_MEMORY):
        New constants.
        (struct Lisp_Save_Value): Replace members area, type0, type1, type2,
        type3 with a single member save_type.  All uses changed.
        (save_type, set_save_pointer, set_save_integer): New functions.
        * print.c (PRINTX): Remove.

        * alloc.c: Remove redundant static declarations.

        * dispnew.c, frame.c, w32fns.c, window.c, xdisp.c, xfns.c:
        Adjust users where appropriate.

2013-03-20  Dmitry Antipov  <dmantipov@yandex.ru>

        * frame.h (struct frame): Drop resx and resy because the same data is
        available from window system-specific output context.  Adjust users.
        (default_pixels_per_inch_x, default_pixels_per_inch_y):
        New functions to provide defaults when no window system available.
        (FRAME_RES_X, FRAME_RES_Y): New macros.
        (NUMVAL): Move from xdisp.c.
        * font.c (font_pixel_size, font_find_for_lface, font_open_for_lface)
        (Ffont_face_attributes, Fopen_font):
        * image.c (gs_load):
        * w32font.c (fill_in_logfont):
        * xdisp.c (calc_pixel_width_or_height):

        * xsettings.c (apply_xft_settings): Drop frame loop and adjust comment.

2013-03-20  Kenichi Handa  <handa@gnu.org>

        * coding.c (syms_of_coding): Initialize disable_ascii_optimization
        to 1 (temporary workaround until a bug related to ASCII
        optimization is fixed).

2013-03-19  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.c (Fwindow_combination_limit, Fset_window_combination_limit):
        Signal error if window is not internal.  Adjust docstring.
        (delete_all_child_windows): Use combination_limit to save the buffer.
        (Fset_window_configuration): Adjust accordingly.
        * print.c (syms_of_print): Initialize debugging output not here...
        (init_print_once): ...but in a new function here.
        * lisp.h (init_print_once): Add prototype.
        * emacs.c (main): Add call to init_print_once.  Adjust comments.

2013-03-18  Dmitry Antipov  <dmantipov@yandex.ru>

        * window.c (window_resize_check, window_resize_apply)
        (window_from_coordinates, recombine_windows, set_window_buffer)
        (make_parent_window, Fwindow_resize_apply, resize_frame_windows)
        (Fsplit_window_internal, Fdelete_window_internal)
        (freeze_window_starts): Use bool for booleans.
        * window.h (window_frame_coordinates, resize_frame_windows)

2013-03-17  Stefan Monnier  <monnier@iro.umontreal.ca>

        * dispnew.c (bitch_at_user): Use `user-error'.

2013-03-17  Ken Brown  <kbrown@cornell.edu>

        * dispextern.h (RGB_PIXEL_COLOR): Move here from image.c.  Use it
        as return type of image_background.  (Bug#13981)
        * image.c (RGB_PIXEL_COLOR): Move to dispextern.h.

2013-03-16  Jan Djärv  <jan.h.d@swipnet.se>

        * nsterm.m (updateFrameSize:): Change resize increments if needed.
        (ns_select): Don't return with result uninitialized.

        * nsterm.h (EmacsSavePanel, EmacsOpenPanel): Add getFilename
        and getDirectory.

        * nsfns.m (ns_filename_from_panel, ns_directory_from_panel):
        New functions.
        (Fns_read_file_name): ret is BOOL.  If ! dir_only_p, don't choose
        directories.  If filename is nil, get directory name (Bug#13932).
        Use getFilename and getDirectory.
        (getFilename, getDirectory): New methods for EmacsSavePanel and
        EmacsOpenPanel.
        (ok:): In EmacsOpenPanel, if we can't choose directories, just return.

2013-03-15  Paul Eggert  <eggert@cs.ucla.edu>

2013-03-15  Kenichi Handa  <handa@gnu.org>

        * insdel.c (insert_from_gap): New arg text_at_gap_tail.
        (adjust_after_replace): Make it back to static.  Delete the third

        * coding.c (detect_ascii): New function.
        (detect_coding): Set coding->head_ascii and coding->eol_seen only
        when the source bytes are actually scanned.  On detecting for
        coding_category_utf_8_auto, call detect_ascii instead of scanning
        source bytes directly.
        (produce_chars): Call insert_from_gap with the new arg 0.
        (encode_coding): Likewise.
        (decode_coding_gap): Control ASCII optimization by the variable
        disable_ascii_optimization instead of #ifndef .. #endif.
        Deccode EOL format according to coding->eol_seen.
        (syms_of_coding): Declare disable-ascii-optimization as a Lisp
        variable.

2013-03-15  Dmitry Antipov  <dmantipov@yandex.ru>

        * region-cache.c (find_cache_boundary, move_cache_gap)
        (insert_cache_boundary, delete_cache_boundaries, set_cache_region):
        Simplify debugging check and convert to eassert.  Adjust comment.
        (pp_cache): Put under ENABLE_CHECKING.

2013-03-14  Eli Zaretskii  <eliz@gnu.org>

        * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
        and incorrect code.  Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
        and WM_ACTIVATEAPP.
        (w32fullscreen_hook): If the frame is visible, reset
        f->want_fullscreen flag after changing the frame size.  If the
        frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
        (Bug#13953)

2013-03-13  Daniel Colascione  <dancol@dancol.org>

        * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
        too so that these builds can use Cygwin's file conversion
        functions.  (We've been building and linking cygw32.o all along
        and just not using it.)

2013-03-13  Paul Eggert  <eggert@cs.ucla.edu>

        File synchronization fixes (Bug#13944).
        * Makefile.in (LIB_FDATASYNC): New macro.
        (LIBES): Use it.
        * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
        * fileio.c (Fwrite_region, write_region_inhibit_fsync):
        Don't worry about HAVE_FSYNC, since a substitute fsync is
        available if the system lacks one.
        (Fwrite_regin): Retry fsync if interrupted.

2013-03-13  Eli Zaretskii  <eliz@gnu.org>

        * w32term.c (w32_read_socket): If the Emacs frame is being
        activated, call w32fullscreen_hook, to make sure the new frame
        dimensions are in effect.  (Bug#13937)

2013-03-13  Dmitry Antipov  <dmantipov@yandex.ru>

        * xdisp.c (init_iterator): Simplify because both character and byte
        positions are either specified or -1.  Add eassert.  Adjust comment.
        * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
        character and byte positions can be obtained from marker.

2013-03-13  Paul Eggert  <eggert@cs.ucla.edu>

        Static checking by Sun C 5.12.
        * alloc.c (buffer_memory_full) [REL_ALLOC]:
        * bytecode.c (exec_byte_code):
        * dispnew.c (init_display):
        * eval.c (error):
        * fileio.c (Fsubstitute_in_file_name):
        * keyboard.c (Fevent_convert_list):
        * keymap.c (Fsingle_key_description):
        * term.c (maybe_fatal, fatal):
        * xfns.c (Fx_display_backing_store, Fx_display_visual_class):
        * xsmfns.c (Fhandle_save_session):
        Omit unreachable code.
        * keymap.c (map_keymap_char_table_item): Cast void * to
        a function pointer type; the C Standard requires this.

        * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
        Include <sys/param.h> unconditionally, as that works elsewhere and
        is simpler here.  Include <sys/sysctl.h> if DARWIN_OS ||
        __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
        and FreeBSD now.

See ChangeLog.12 for earlier changes.
