2011-08-05 Eli Zaretskii *xdisp.c (display_line): Release buffer allocated for shelved bidi cache. (Bug#9221) * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total amount allocated this far in `bidi_cache_total_alloc'. (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if non-zero, only free the data buffer without restoring the cache contents. All callers changed. * dispextern.h (bidi_unshelve_cache): Update prototype. * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to) (move_it_in_display_line, move_it_to) (move_it_vertically_backward, move_it_by_lines): Replace the call to xfree to an equivalent call to bidi_unshelve_cache.

Initialize cached_prev_pos to -1. Fixes slow-down at the beginning of a buffer. 2011-07-23 Eli Zaretskii * xdisp.c (move_it_in_display_line_to): Record the best matching position for TO_CHARPOS while scanning the line, and restore it on exit if none of the characters scanned was an exact match. Fixes vertical-motion and pos-visible-in-window-p when exact match is impossible due to invisible text, and the lines are truncated. 2011-07-22 Eli Zaretskii * xdisp.c (compute_stop_pos_backwards): New function. (handle_stop_backwards): Revert last change. (next_element_from_buffer): Call compute_stop_pos_backwards to find a suitable prev_stop when we find ourselves before base_level_stop. Remove the funky search for 1000 character positions back. 2011-07-19 Eli Zaretskii Fix a significant slow-down of vertical-motion when leaning on C-n or C-p in a fontified buffer. * xdisp.c (reseat): Don't look for prev_stop, as that could mean a very long run. (next_element_from_buffer): When iterator oversteps prev_pos backwards, don't search for a new prev_stop more than 1000 characters back. (handle_stop_backwards): Don't assume that CHARPOS is necessarily a stop_pos. (compute_display_string_pos): Check also BUF_OVERLAY_MODIFF for a match, when testing the cached display string position for applicability. 2011-07-16 Eli Zaretskii * xdisp.c : Cache for last found display string position. (compute_display_string_pos): Return the cached position if asked about the same buffer. 2011-07-14 Eli Zaretskii * bidi.c (bidi_cache_fetch_state, bidi_cache_search) (bidi_cache_find_level_change, bidi_cache_ensure_space) (bidi_cache_iterator_state, bidi_cache_find) (bidi_find_other_level_edge, bidi_cache_start_stack): All variables related to cache indices are now EMACS_INT. 2011-07-09 Eli Zaretskii * bidi.c (bidi_fetch_char): Fix the type of `len' according to what STRING_CHAR_AND_LENGTH expects. * xdisp.c (move_it_in_display_line_to): Record prev_method and prev_pos immediately before the call to set_iterator_to_next. Fixes cursor motion in bidi-reordered lines with stretch glyphs and strings displayed in margins. (Bug#8133) (Bug#8867) Return MOVE_POS_MATCH_OR_ZV only if iterator position is past TO_CHARPOS. (pos_visible_p): Support positions in bidi-reordered lines. Save and restore bidi cache. 2011-07-08 Eli Zaretskii * xdisp.c (move_it_in_display_line_to): If iterator ended up at EOL, but we never saw any buffer positions smaller than to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor motion in bidi-reordered lines. 2011-07-07 Eli Zaretskii * xdisp.c (find_row_edges): If ROW->start.pos gives position smaller than min_pos, use it as ROW->minpos. (Bug#7616) 2011-07-05 Eli Zaretskii * dispnew.c (buffer_posn_from_coords): Save and restore the bidi cache around display iteration. * window.c (Fwindow_end, window_scroll_pixel_based) (displayed_window_lines, Frecenter): Save and restore the bidi cache around display iteration. * bidi.c (bidi_unshelve_cache): Ensure we have enough space before restoring the shelved cache. (bidi_cache_ensure_space): Don't assume the required size is just one BIDI_CACHE_CHUNK away. * xdisp.c (back_to_previous_visible_line_start, reseat_1) (init_iterator): Empty the bidi cache "stack". 2011-07-03 Eli Zaretskii * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): New functions. * dispextern.h (bidi_shelve_cache, bidi_unshelve_cache): Declare prototypes. * xdisp.c (SAVE_IT, RESTORE_IT): New macros.

(pop_it): Call iterate_out_of_display_property only if we are popping after iteration over a string that came from a display property. Fix a typo in popping stretch info. Add an assertion for verifying that the iterator position is in sync with the bidi iterator. (handle_single_display_spec, get_overlay_strings_1) (push_display_prop): Fix initialization of paragraph direction for string when that of the parent object is not yet determined. 2011-07-01 Eli Zaretskii * dispextern.h (struct bidi_string_data): New member `unibyte'. * xdisp.c (handle_single_display_spec, next_overlay_string) (get_overlay_strings_1, reseat_1, reseat_to_string) (push_display_prop): Set up the `unibyte' member of bidi_it.string correctly. Don't assume unibyte strings are not bidi-reordered. (compute_display_string_pos) (compute_display_string_end): Fix handling the case of C string. * bidi.c (bidi_count_bytes, bidi_char_at_pos): Accept an additional argument UNIBYTE, and support unibyte strings. All callers changed. (bidi_fetch_char): Support unibyte strings. 2011-06-25 Eli Zaretskii * xdisp.c (set_iterator_to_next, get_visually_first_element): Use it->bidi_it.string.schars rather than it->string_nchars when testing whether we're beyond string end, because string_nchars is zero for strings that come from overlays and display properties. * bidi.c (bidi_cache_iterator_state): Fix a bug with testing character positions against the cached range, when we use a stacked cache. * xdisp.c (push_it, pop_it): Save and restore it. * dispextern.h (struct iterator_stack_entry): New member paragraph_embedding. * xdisp.c (handle_single_display_spec, next_overlay_string) (get_overlay_strings_1, push_display_prop): Set up the bidi iterator for displaying display or overlay strings. (forward_to_next_line_start): Don't use the shortcut if bidi-iterating. (back_to_previous_visible_line_start): If handle_display_prop pushed the iterator stack, restore the internal state of the bidi iterator by calling bidi_pop_it same number of times. (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero, and we are bidi-iterating, don't decrement the iterator position; instead, set the first_elt flag in the bidi iterator, to produce the same effect. (reseat_1): Remove redundant setting of string_from_display_prop_p. (push_display_prop): xassert that we are iterating a buffer. * bidi.c (bidi_cache_start_stack, bidi_push_it): Use IT_STACK_SIZE. 2011-06-24 Eli Zaretskii * xdisp.c (push_it, pop_it): Save and restore the state of the bidi iterator.

(next_element_from_c_string): Handle the case of the first string character that is not the first one in the visual order. (get_visually_first_element): New function, refactored from common parts of next_element_from_buffer, next_element_from_string, and next_element_from_c_string. 2011-06-16 Eli Zaretskii * xdisp.c (init_iterator): Don't initialize it->bidi_p for strings here. (reseat_to_string): Initialize it->bidi_p for strings here. (next_element_from_string, next_element_from_c_string) (next_element_from_buffer): Add xassert's for correspondence between IT's object being iterated and it->bidi_it.string structure. * bidi.c (bidi_level_of_next_char): Fix the logic for looking up the sentinel state in the cache. 2011-06-13 Eli Zaretskii * xdisp.c (compute_display_string_pos) (compute_display_string_end, reseat_to_string): Don't assume it->bidi_it.string.s always points to string.lstring's data. * bidi.c (bidi_fetch_char, bidi_paragraph_init) (bidi_resolve_explicit_1, bidi_resolve_explicit) (bidi_resolve_weak, bidi_level_of_next_char): Don't assume string.s always points to string.lstring's data. 2011-06-11 Eli Zaretskii * xdisp.c (set_iterator_to_next): Advance string position correctly when padding it with blanks. 2011-06-11 Eli Zaretskii * xdisp.c (next_element_from_buffer): Improve commentary for when the iterator is before prev_stop. (init_iterator): Initialize bidi_p from the default value of bidi-display-reordering, not from buffer-local value. Use the buffer-local value only if initializing for buffer iteration. (handle_invisible_prop): Support invisible properties on strings that are being bidi-reordered. (reseat_to_string): Enable bidi-related code. (set_iterator_to_next): Support bidi reordering of C strings and Lisp strings. (next_element_from_string): Support bidi reordering of Lisp strings. (handle_stop_backwards): Support Lisp strings as well. (display_mode_line, display_mode_element): Temporarily force L2R paragraph direction. (display_string): Support display of R2L glyph rows. Use IT_STRING_CHARPOS when displaying from a Lisp string. 2011-06-10 Eli Zaretskii * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize itb.string.lstring. (compute_display_string_pos, compute_display_string_end): Fix calculation of the object to scan. Fixes an error when using arrow keys. (next_element_from_buffer): Don't abort when IT_CHARPOS is before base_level_stop; instead, set base_level_stop to BEGV. Fixes crashes in vertical-motion. 2011-06-09 Eli Zaretskii * xdisp.c (compute_display_string_pos): First arg is now struct `text_pos *'; all callers changed. Support display properties on Lisp strings. (compute_display_string_end): Support display properties on Lisp strings. (init_iterator, reseat_1, reseat_to_string): Initialize the string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS when iterating on a string not from display properties). * bidi.c (bidi_fetch_char): Support strings with display properties. * dispextern.h (struct bidi_string_data): New member bufpos. (compute_display_string_pos): Update prototype. 2011-06-09 Eli Zaretskii * bidi.c (bidi_level_of_next_char): Allow the sentinel "position" to pass the test for valid cached positions. * xdisp.c (init_iterator): Call bidi_init_it only of a valid buffer position was specified. Initialize paragraph_embedding to L2R. (reseat_to_string): Initialize the bidi iterator (for now ifdef'ed out). (display_string): If we need to ignore text properties of LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The original value of -1 will not work with bidi.) * dispextern.h (struct bidi_string_data): New member lstring. 2011-06-09 Eli Zaretskii * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to NULL (avoids a crash in bidi_paragraph_init). 2011-06-08 Eli Zaretskii * bidi.c (bidi_paragraph_info): Delete unused struct. (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT. (bidi_cache_start): New variable. (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not to zero. (bidi_cache_fetch_state, bidi_cache_search) (bidi_cache_find_level_change, bidi_cache_iterator_state) (bidi_cache_find, bidi_peek_at_next_level) (bidi_level_of_next_char, bidi_find_other_level_edge) (bidi_move_to_visually_next): Compare cache index with bidi_cache_start rather than with zero. (bidi_fetch_char): Accept new argument STRING; all callers changed. Support iteration over a string. (bidi_paragraph_init, bidi_resolve_explicit_1) (bidi_resolve_explicit, bidi_resolve_weak) (bidi_level_of_next_char, bidi_move_to_visually_next): Support iteration over a string. (bidi_set_sor_type, bidi_resolve_explicit_1) (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit can now be zero (for strings); special values 0 and -1 were changed to -1 and -2, respectively. (bidi_char_at_pos): New function. (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak): Call it instead of FETCH_MULTIBYTE_CHAR. (bidi_move_to_visually_next): Abort if charpos or bytepos were not initialized to valid values. (bidi_init_it): Don't initialize charpos and bytepos with invalid values. * xdisp.c (compute_display_string_pos) (compute_display_string_end): Accept additional argument STRING.

(compute_display_string_pos, compute_display_string_end): Update prototypes. 2011-06-04 Eli Zaretskii * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int. 2011-06-03 Eli Zaretskii * bidi.c (bidi_fetch_char_advance): Remove unused and unimplemented function. 2011-05-28 Eli Zaretskii * xdisp.c (set_cursor_from_row): Set start and stop points according to the row's direction when priming the loop that looks for the glyph on which to display cursor. (single_display_spec_intangible_p): Function deleted. (display_prop_intangible_p): Reimplement to call handle_display_spec instead of single_display_spec_intangible_p. Accept 3 additional arguments needed by handle_display_spec. This fixes incorrect cursor motion across display property with complex values: lists, `(when COND...)' forms, etc. (single_display_spec_string_p): Support property values that are lists with the argument STRING its top-level element. (display_prop_string_p): Fix the condition for processing a property that is a list to be consistent with handle_display_spec. * keyboard.c (adjust_point_for_property): Adjust the call to display_prop_intangible_p to its new signature. * dispextern.h (display_prop_intangible_p): Adjust prototype. 2011-05-21 Eli Zaretskii * xdisp.c (handle_display_spec): New function, refactored from the last portion of handle_display_prop. (compute_display_string_pos): Accept additional argument FRAME_WINDOW_P. Call handle_display_spec to determine whether the value of a `display' property is a "replacing spec". (handle_single_display_spec): Accept 2 additional arguments BUFPOS and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from the display property, but just return a value indicating whether the display property will replace the characters it covers. (Fcurrent_bidi_paragraph_direction): Initialize the nchars and frame_window_p members of struct bidi_it. * bidi.c (bidi_fetch_char): Accept additional argument FRAME_WINDOW_P and pass it to compute_display_string_pos. All callers changed. (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use it to initialize the frame_window_p member of struct bidi_it. * dispextern.h (struct bidi_it): New member frame_window_p. (bidi_init_it, compute_display_string_pos): Update prototypes. 2011-05-14 Eli Zaretskii * xdisp.c (compute_display_string_pos): Non-trivial implementation. (compute_display_string_end): New function. (push_it): Accept second argument POSITION, where pop_it should jump to continue iteration. * dispextern.h (compute_display_string_end): Declare prototype. * bidi.c (bidi_resolve_explicit_1): Use ZV for disp_pos. (bidi_fetch_char): Implement support for runs of characters covered by display strings. * bidi.c (bidi_fetch_char): Accept also character position corresponding to BYTEPOS. DISP_POS is now a character position, not a byte position. All callers changed. (bidi_cache_iterator_state, bidi_resolve_explicit_1) (bidi_resolve_explicit, bidi_resolve_weak) (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if bidi_it->nchars is non-positive. (bidi_level_of_next_char): Don't try to lookup the cache for the next/previous character if nothing is cached there yet, or if we were just reseat()'ed to a new position. (bidi_paragraph_init, bidi_resolve_explicit_1) (bidi_level_of_next_char): Fix arguments in the calls to bidi_fetch_char. 2011-05-10 Eli Zaretskii * xdisp.c (compute_display_string_pos): New function. (reseat_1): Initialize bidi_it.disp_pos. * bidi.c (bidi_copy_it): Use offsetof. (bidi_fetch_char, bidi_fetch_char_advance): New functions. (bidi_cache_search, bidi_cache_iterator_state) (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak) (bidi_level_of_next_char, bidi_move_to_visually_next): Support character positions inside a run of characters covered by a display string. (bidi_paragraph_init, bidi_resolve_explicit_1) (bidi_level_of_next_char): Call bidi_fetch_char and bidi_fetch_char_advance instead of FETCH_CHAR and FETCH_CHAR_ADVANCE. (bidi_init_it): Initialize new members. (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro definitions. (bidi_explicit_dir_char): Lookup character type in bidi_type_table, instead of using explicit *_CHAR codes. (bidi_resolve_explicit, bidi_resolve_weak): Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of bidirectional text is supported only in multibyte buffers. * dispextern.h (struct bidi_it): New members nchars and disp_pos. ch_len is now EMACS_INT. (compute_display_string_pos): Declare prototype. 2011-05-09 Andreas Schwab * w32menu.c (set_frame_menubar): Fix submenu allocation. 2011-05-07 Eli Zaretskii * w32console.c (Fset_screen_color): Doc fix. (Fget_screen_color): New function. (syms_of_ntterm): Defsubr it. * callproc.c (call_process_cleanup): Don't close and unlink the temporary file if Fcall_process didn't create it in the first place. (Fcall_process): Don't create tempfile if stdout of the child process will be redirected to a file specified with `:file'. Don't try to re-open tempfile in that case, and set fd[0] to -1 as cue to call_process_cleanup not to close that handle. 2011-05-07 Ben Key * makefile.w32-in: The bootstrap-temacs rule now makes use of one of two shell specific rules, either bootstrap-temacs-CMD or bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical to the previous implementation of the bootstrap-temacs rule. The bootstrap-temacs-CMD rule is similar to the previous implementation of the bootstrap-temacs rule except that it makes use of the ESC_CFLAGS variable instead of the CFLAGS variable. These changes, along with some changes to nt/configure.bat, nt/gmake.defs, and nt/nmake.defs, are required to extend my earlier fix to add support for --cflags and --ldflags options that include quotes so that it works whether make uses cmd or sh as the shell. 2011-05-06 Michael Albinus * dbusbind.c (QCdbus_type_unix_fd): Declare static. (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it is a constant. (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or a string. Handle both cases. (Fdbus_call_method_asynchronously, Fdbus_register_signal) (Fdbus_register_method): Use Qinvalid_function. 2011-05-06 Juanma Barranquero * makefile.w32-in: Update dependencies. (LISP_H): Add inttypes.h and stdin.h. (PROCESS_H): Add unistd.h. 2011-05-06 Eli Zaretskii * lread.c: Include limits.h (fixes the MS-Windows build broken by 2011-05-06T07:13:19Z!eggert@cs.ucla.edu). 2011-05-06 Paul Eggert * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local. * term.c (vfatal): Remove stray call to va_end. It's not needed and the C Standard doesn't allow it here anyway. Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux. * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545) * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM bytes. * term.c: Don't include , as does that. * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering. * process.c (Fformat_network_address): Fix typo: args2 -> *args2. * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times). * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601). * charset.h (struct charset.code_space): Now has 15 elements, not 16. * charset.c (Fdefine_charset_internal): Don't initialize charset.code_space[15]. The value was garbage, on hosts with 32-bit int (Bug#8600). * lread.c (read_integer): Be more consistent with string-to-number. Use string_to_number to do the actual conversion; this avoids rounding errors and fixes some other screwups. Without this fix, for example, #x1fffffffffffffff was misread as -2305843009213693952. (digit_to_number): Move earlier, for benefit of read_integer. Return -1 if the digit is out of range for the base, -2 if it is not a digit in any supported base. (Bug#8602) * doprnt.c (doprnt): Support arbitrary pI values, such as "I64". * dispnew.c (scrolling_window): Return 1 if we scrolled, to match comment at start of function. This also removes a GCC warning about overflow in a 32+64-bit port. * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify. * dbusbind.c: Do not use XPNTR on a value that may be an integer. Reported by Stefan Monnier in . (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages): Use SYMBOLP-guarded XSYMBOL, not XPNTR. * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t. (EMACS_UINTPTR): Likewise, with uintptr_t. * lisp.h: Prefer 64-bit EMACS_INT if available. (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit on 32-bit hosts that have 64-bit int, so that they can access large files. However, temporarily disable this change unless the temporary symbol WIDE_EMACS_INT is defined. * lread.c, process.c: Do not include ; lisp.h does it now. Prefer intptr_t/uintptr_t for integers the same widths as pointers. This removes an assumption that EMACS_INT and long are the same width as pointers. The assumption is true for Emacs porting targets now, but we want to make other targets possible. * lisp.h: Include , for INTPTR_MAX, UINTPTR_MAX. (EMACS_INTPTR, EMACS_UINTPTR): New macros. In the rest of the code, change types of integers that hold casted pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically replacing EMACS_INT, long, EMACS_UINT, and unsigned long. (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed. (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here. No need to cast type when ORing. (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR. * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast. * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to assume EMACS_INT is the same width as char *. * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb): (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item): Remove no-longer-needed casts. (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback): (xg_tool_bar_help_callback, xg_make_tool_item): Use EMACS_INTPTR to hold an integer that will be cast to void *; this can avoid a GCC warning if EMACS_INT is not the same width as void *. * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast. * xdisp.c (display_echo_area_1, resize_mini_window_1): (current_message_1, set_message_1): Use a local to convert to proper width without a cast. * xmenu.c (dialog_selection_callback): Likewise. * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long. Also, don't assume VALBITS / RAND_BITS is less than 5, and don't rely on undefined behavior when shifting a 1 left into the sign bit. * lisp.h (get_random): Change signature to match. * lread.c (hash_string): Use size_t, not int, for hash computation. Normally we prefer signed values; but hashing is special, because it's better to use unsigned division on hash table sizes so that the remainder is nonnegative. Also, size_t is the natural width for hashing into memory. The previous code used 'int', which doesn't retain enough info to hash well into very large tables. (oblookup, oblookup_last_bucket_number, Funintern): Likewise. * dbusbind.c: Don't possibly lose pointer info when converting. (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages): Use XPNTR rather than XHASH, so that the high-order bits of the pointer aren't lost when converting through void *. * eval.c (Fautoload): Don't double-shift a pointer. * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long. 2011-05-06 Juanma Barranquero * gnutls.c (DEF_GNUTLS_FN): * image.c (DEF_IMGLIB_FN): Make function pointers static. 2011-05-05 Andreas Schwab * lread.c (lisp_file_lexically_bound_p): Stop scanning at end marker.

(syms_of_gnutls) : Initialize and staticpro it. (syms_of_gnutls) : defsubr it. * image.c: Include w32.h. (Vimage_type_cache): Delete. (syms_of_image) : Don't initialize and staticpro it.

(wait_reading_process_output): Call emacs_gnutls_record_check_pending instead of gnutls_record_check_pending. * callproc.c, emacs.c: Include lisp.h before w32.h, not after. 2011-05-04 Teodor Zlatanov * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options instead of :keyfiles. Give GnuTLS the keylist and the CRL lists as passed in. 2011-05-03 Jan Djärv * xterm.c (x_set_frame_alpha): Do not set property on anything else than FRAME_X_OUTER_WINDOW (Bug#8608). 2011-05-02 Juanma Barranquero * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596) 2011-05-02 Juanma Barranquero * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon) (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again) (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake) (gnutls_global_initialized, Qgnutls_bootprop_priority) (Qgnutls_bootprop_trustfiles, Qgnutls_bootprop_keyfiles) (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel) (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags) (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error) (Qgnutls_bootprop_callbacks_verify): Make static. 2011-05-01 Andreas Schwab * callproc.c: Indentation fixup. * sysdep.c (wait_for_termination_1): Make static. (wait_for_termination, interruptible_wait_for_termination): Move after wait_for_termination_1. 2011-05-01 Lars Magne Ingebrigtsen * sysdep.c (interruptible_wait_for_termination): New function which is like wait_for_termination, but allows keyboard interruptions. * callproc.c (Fcall_process): Add (:file "file") as an option for the STDOUT buffer. (Fcall_process_region): Ditto. 2011-04-30 Eli Zaretskii * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)' rather than `XVECTOR (FOO)->size'. * process.c: Remove HAVE_INTTYPES_H condition from inclusion of inttypes.h, as a gnulib replacement is used if it not available in system headers. 2011-04-21 Eli Zaretskii Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files. * fileio.c (Finsert_file_contents): Don't limit file size to 1/4 of MOST_POSITIVE_FIXNUM. (Bug#8528) * coding.c (coding_alloc_by_realloc): Error out if destination will grow beyond MOST_POSITIVE_FIXNUM. (decode_coding_emacs_mule): Abort if there isn't enough place in charbuf for the composition carryover bytes. Reserve an extra space for up to 2 characters produced in a loop. (decode_coding_iso_2022): Abort if there isn't enough place in charbuf for the composition carryover bytes. 2011-04-21 Eli Zaretskii * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of aborting when %lld or %lll format is passed.

(Bug#7952) * doprnt.c (doprnt): Fix the case where a multibyte sequence produced by %s or %c overflows available buffer space. (Bug#8545) 2011-04-28 Paul Eggert * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545). (SIZE_MAX): Move defn after all includes, as they might #define it. 2011-04-28 Juanma Barranquero * w32.c (init_environment): Warn about defaulting HOME to C:\. 2011-04-28 Juanma Barranquero * keyboard.c (Qdelayed_warnings_hook): Define.

(Bug#8545). 2011-04-28 Juanma Barranquero * w32fns.c (Fx_change_window_property, Fx_delete_window_property) (Fx_window_property): #if-0 the whole functions, not just the bodies. 2011-04-27 Paul Eggert * doprnt.c (doprnt): Support "ll" length modifier, for long long. 2011-04-27 Juanma Barranquero * makefile.w32-in: Update dependencies. 2011-04-27 Eli Zaretskii Improve `doprnt' and its usage. (Bug#8545) * doprnt.c (doprnt): Make sure `format' is never accessed beyond `format_end'. Remove support for %l as a conversion specifier. Don't use xrealloc. Improve diagnostics when the %l size modifier is used. Update the commentary. * eval.c (verror): Simplify calculation of size_t. * coding.c (Ffind_operation_coding_system): Fix diagnostic error messages. 2011-04-27 Yoshiaki Kasahara (tiny change) * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing change. 2011-04-27 Paul Eggert * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF. This makes this file independent of the recent pseudovector change. 2011-04-26 Paul Eggert * keyboard.c (handle_user_signal): Fix pointer signedness problem. * gnutls.c (emacs_gnutls_handle_error): Remove unused local. (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *. Remove unused local. (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0. * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546) GCC 4.6.0 optimizes based on type-based alias analysis. For example, if b is of type struct buffer * and v of type struct Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size != &v->size, and therefore "v->size = 1; b->size = 2; return v->size;" must therefore return 1. This assumption is incorrect for Emacs, since it type-puns struct Lisp_Vector * with many other types. To fix this problem, this patch adds a new type struct vectorlike_header that documents the constraints on layout of vectors and pseudovectors, and helps optimizing compilers not get fooled by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons. * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of the size member. (XSETPVECTYPE): Rewrite in terms of new macro. (XSETPVECTYPESIZE): New macro, specifying both type and size. This is a bit clearer, and further avoids the possibility of undesirable aliasing. (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size. (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR. (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE, since Lisp_Subr is a special case (no "next" field). (ASIZE): Now uses header.size rather than size. All previous uses of XVECTOR (foo)->size replaced to use this macro, to avoid the hassle of writing XVECTOR (foo)->header.size. (struct vectorlike_header): New type. (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the object, to help avoid aliasing. (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP. (SUBRP): Likewise, since Lisp_Subr is a special case. * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table): (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector): (struct Lisp_Hash_Table): Combine first two members into a single struct vectorlike_header member. All uses of "size" and "next" members changed to be "header.size" and "header.next". * buffer.h (struct buffer): Likewise. * font.h (struct font_spec, struct font_entity, struct font): Likewise. * frame.h (struct frame): Likewise. * process.h (struct Lisp_Process): Likewise. * termhooks.h (struct terminal): Likewise. * window.c (struct save_window_data, struct saved_window): Likewise. * window.h (struct window): Likewise. * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector): Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems. * buffer.c (init_buffer_once): Likewise. * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a special case. * process.c (Fformat_network_address): Use local var for size, for brevity. * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR. Make the Lisp reader and string-to-float more consistent (Bug#8525) * data.c (atof): Remove decl; no longer used or needed. (digit_to_number): Move to lread.c. (Fstring_to_number): Use new string_to_number function, to be consistent with how the Lisp reader treats infinities and NaNs. Do not assume that floating-point numbers represent EMACS_INT without losing information; this is not true on most 64-bit hosts. Avoid double-rounding errors, by insisting on integers when parsing non-base-10 numbers, as the documentation specifies. * lisp.h (string_to_number): New decl, replacing ... (isfloat_string): Remove. * lread.c: Include , for uintmax_t and strtoumax. (read1): Do not accept +. and -. as integers; this appears to have been a coding error. Similarly, do not accept strings like +-1e0 as floating point numbers. Do not report overflow for integer overflows unless the base is not 10 which means we have no simple and reliable way to continue. Break out the floating-point parsing into a new function string_to_number, so that Fstring_to_number parses floating point numbers consistently with the Lisp reader. (digit_to_number): Moved here from data.c. Make it static inline. (E_CHAR, EXP_INT): Remove, replacing with ... (E_EXP): New macro, to solve the "1.0e+" problem mentioned below. (string_to_number): New function, replacing isfloat_string. This function checks for valid syntax and produces the resulting Lisp float number too. Rework it so that string-to-number no longer mishandles examples like "1.0e+". Use strtoumax, so that overflow for non-base-10 numbers is reported only when there's no portable and simple way to convert to floating point. * textprop.c (set_text_properties_1): Rewrite for clarity, and to avoid GCC warning about integer overflow. * intervals.h (struct interval): Use EMACS_INT for members where EMACS_UINT might cause problems. See . (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed. * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT. All uses changed. (offset_intervals): Tell GCC not to worry about length overflow when negating a negative length. * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static. (overrun_check_free): Likewise. * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check in the common case where SDATA_DATA_OFFSET is a multiple of Emacs word size. * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10. (gnutls_make_error): Rename local to avoid shadowing. (gnutls_emacs_global_deinit): ifdef out; not used. (Fgnutls_boot): Use const for pointer to readonly storage. Comment out unused local. Fix pointer signedness problems. * lread.c (openp): Don't stuff size_t into an 'int'. Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning about possible signed overflow. * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10. (GDK_KEY_g): Don't define if already defined. (xg_prepare_tooltip): Avoid pointer signedness problem. (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts. * process.c (Fnetwork_interface_info): Avoid left-shift undefined behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts. * xfns.c (Fx_window_property): Simplify a bit, to make a bit faster and to avoid GCC 4.6.0 warning. * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise. * fns.c (internal_equal): Don't assume size_t fits in int. * alloc.c (compact_small_strings): Tighten assertion a little. Replace pEd with more-general pI, and fix some printf arg casts. * lisp.h (pI): New macro, generalizing old pEd macro to other conversion specifiers. For example, use "...%"pI"d..." rather than "...%"pEd"...". (pEd): Remove. All uses replaced with similar uses of pI. * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise. * alloc.c (check_pure_size): Don't overflow by converting size to int. * bidi.c (bidi_dump_cached_states): Use pI to avoid cast. * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort. * dbusbind.c (xd_append_arg): Use pI to avoid cast. (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise. * font.c (font_unparse_xlfd): Avoid potential buffer overrun on 64-bit hosts. (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts. * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts. * print.c (safe_debug_print, print_object): Likewise. (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT to int. Use pI instead of if-then-else-abort. Use %p to avoid casts, avoiding the 0 flag, which is not portable. * process.c (Fmake_network_process): Use pI to avoid cast. * region-cache.c (pp_cache): Likewise. * xdisp.c (decode_mode_spec): Likewise. * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined behavior on 64-bit hosts with printf arg. * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag. (x_stop_queuing_selection_requests): Likewise. (x_get_window_property): Don't truncate byte count to an 'int' when tracing. * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right here, since it parses constructs like leading '-' and spaces, which are not wanted; and it overflows with large numbers. Instead, simply match F[0-9]+, which is what is wanted anyway. * alloc.c: Remove unportable assumptions about struct layout. (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros. (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data): (allocate_vectorlike, make_pure_vector): Use the new macros, plus offsetof, to remove unportable assumptions about struct layout. These assumptions hold on all porting targets that I know of, but they are not guaranteed, they're easy to remove, and removing them makes further changes easier. * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks". This doesn't fix a bug but makes the code clearer. (string_overrun_cookie): Now const. Use initializers that don't formally overflow signed char, to avoid warnings. (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that can cause Emacs to crash when string overrun checking is enabled. (allocate_buffer): Don't assume sizeof (struct buffer) is a multiple of sizeof (EMACS_INT); it need not be, if alignof(EMACS_INT) < sizeof (EMACS_INT). (check_sblock, check_string_bytes, check_string_free_list): Protoize. 2011-04-26 Juanma Barranquero * keyboard.c (QCrtl): Rename from Qrtl. All uses changed. 2011-04-26 Teodor Zlatanov * gnutls.c (emacs_gnutls_handshake): Return an error if we're not supposed to be handshaking. (Bug#8556) Reported by Paul Eggert . 2011-04-26 Daniel Colascione * lisp.h (Qdebug): List symbol. * eval.c (Qdebug): Restore global linkage. * keyboard.c (debug-on-event): New variable. (handle_user_signal): Break into debugger when debug-on-event matches the current signal symbol. 2011-04-25 Dan Nicolaescu * alloc.c (check_sblock, check_string_bytes) (check_string_free_list): Convert to standard C. 2011-04-25 Teodor Zlatanov * w32.c (emacs_gnutls_push): Fix typo. 2011-04-25 Eli Zaretskii * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about "cast to pointer from integer of different size". Improve doprnt and its use in verror. (Bug#8545) * doprnt.c (doprnt): Document the set of format control sequences supported by the function. Use SAFE_ALLOCA instead of always using `alloca'. * eval.c (verror): Don't limit the buffer size at size_max-1, that is one byte too soon. Don't use xrealloc; instead xfree and xmalloc anew. 2011-04-24 Teodor Zlatanov * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the callbacks stage. * gnutls.c: Renamed global_initialized to gnutls_global_initialized. Added internals for the :verify-hostname-error, :verify-error, and :verify-flags parameters of `gnutls-boot' and documented those parameters in the docstring. Start callback support. (emacs_gnutls_handshake): Add Woe32 support. Retry handshake unless a fatal error occured. Call gnutls_alert_send_appropriate on error. Return error code.

(emacs_gnutls_push): Likewise. 2011-04-24 Claudio Bley (tiny change) * process.c (wait_reading_process_output): Check if GnuTLS buffered some data internally if no FDs are set for TLS connections. * makefile.w32-in (OBJ2): Add gnutls.$(O).

(syms_of_character): Don't defsubr it. : Deleted. 2011-04-23 Eli Zaretskii Fix doprnt so it could be used again safely in `verror'. (Bug#8435) * doprnt.c: Include limits.h. (SIZE_MAX): New macro. (doprnt): Return a size_t value. 2nd arg is now size_t. Many local variables are now size_t instead of int or unsigned. Improve overflow protection. Support `l' modifier for integer conversions. Support %l conversion. Don't assume an EMACS_INT argument for integer conversions and for %c. * lisp.h (doprnt): Restore prototype. * makefile.w32-in ($(BLD)/callint.$(O)): Depend on $(SRC)/character.h. * Makefile.in (base_obj): Add back doprnt.o. * deps.mk (doprnt.o): Add back prerequisites.

(Bug#8496) 2011-04-13 Eli Zaretskii * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init when at ZV. (Bug#8487) 2011-04-12 Andreas Schwab * charset.c (Fclear_charset_maps): Use xfree instead of free. (Bug#8437) * keyboard.c (parse_tool_bar_item): Likewise. * sound.c (sound_cleanup, alsa_close): Likewise. * termcap.c (tgetent): Likewise. * xfns.c (x_default_font_parameter): Likewise. * xsettings.c (read_and_apply_settings): Likewise. * alloc.c (overrun_check_malloc, overrun_check_realloc) (overrun_check_free): Protoize. 2011-04-12 Paul Eggert * sysdep.c (emacs_read, emacs_write): Check for negative sizes since callers should never pass a negative size. Change the signature to match that of plain 'read' and 'write'; see . * lisp.h: Update prototypes of emacs_write and emacs_read. 2011-04-11 Eli Zaretskii * xdisp.c (redisplay_window): Don't try to determine the character position of the scroll margin if the window start point w->startp is outside the buffer's accessible region. (Bug#8468) 2011-04-10 Eli Zaretskii Fix write-region and its subroutines for buffers > 2GB. * fileio.c (a_write, e_write): Modify declaration of arguments and local variables to support buffers larger than 2GB. (Fcopy_file): Use EMACS_INT for return value of emacs_read. * sysdep.c (emacs_write, emacs_read): Use ssize_t for last argument, local variables, and return value. * lisp.h: Update prototypes of emacs_write and emacs_read. * sound.c (vox_write): Use ssize_t for return value of emacs_write. 2011-04-10 Paul Eggert * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack. Fix more problems found by GCC 4.6.0's static checks. * xdisp.c (vmessage): Use a better test for character truncation. * charset.c (load_charset_map): <, not <=, for optimization, and to avoid potential problems with integer overflow. * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise. * casetab.c (set_identity, shuffle): Likewise. * editfns.c (Fformat): Likewise. * syntax.c (skip_chars): Likewise. * xmenu.c (set_frame_menubar): Allocate smaller local vectors. This also lets GCC 4.6.0 generate slightly better loop code. * callint.c (Fcall_interactively): <, not <=, for optimization. (Fcall_interactively): Count the number of arguments produced, not the number of arguments given. This is simpler and lets GCC 4.6.0 generate slightly better code. * ftfont.c: Distingish more carefully between FcChar8 and char. The previous code passed unsigned char * to a functions like strlen and xstrcasecmp that expect char *, which does not conform to the C standard. (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for arguments to FcPatternGetString, and explicitly cast FcChar8 * to char * when the C standard requires it. * keyboard.c (read_char): Remove unused var. * eval.c: Port to Windows vsnprintf (Bug#8435). Include . (SIZE_MAX): Define if the headers do not. (verror): Do not give up if vsnprintf returns a negative count. Instead, grow the buffer. This ports to Windows vsnprintf, which does not conform to C99. Problem reported by Eli Zaretskii. Also, simplify the allocation scheme, by avoiding the need for calling realloc, and removing the ALLOCATED variable. * eval.c (verror): Initial buffer size is 4000 (not 200) bytes. Remove invocations of doprnt, as Emacs now uses vsnprintf. But keep the doprint source code for now, as we might revamp it and use it again (Bug#8435). * lisp.h (doprnt): Remove. * Makefile.in (base_obj): Remove doprnt.o. * deps.mk (doprnt.o): Remove. error: Print 32- and 64-bit integers portably (Bug#8435). Without this change, on typical 64-bit hosts error ("...%d...", N) was used to print both 32- and 64-bit integers N, which relied on undefined behavior. * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd): New macro. * lisp.h (error, verror): Mark as printf-like functions. * eval.c (verror): Use vsnprintf, not doprnt, to do the real work. Report overflow in size calculations when allocating printf buffer. Do not truncate output string at its first null byte. * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work. Truncate the output at a character boundary, since vsnprintf does not do that. * charset.c (check_iso_charset_parameter): Convert internal character to string before calling 'error', since %c now has the printf meaning. * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int overflow when computing char to be passed to 'error'. Do not pass Lisp_Object to 'error'; pass the integer instead. * nsfns.m (Fns_do_applescript): Use int, not long, since it's formatted with plain %d. * eval.c (internal_lisp_condition_case): Don't pass spurious arg. * keyboard.c (access_keymap_keyremap): Print func name, not garbage. * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int. * xterm.c (x_catch_errors): Remove duplicate declaration. * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too. * xdisp.c, lisp.h (message_nolog): Remove; unused. 2011-04-10 Jim Meyering use ssize_t and size_t for read- and write-like emacs_gnutls_* functions * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like: return ssize_t not "int", and use size_t as the buffer length. (emacs_gnutls_write): Likewise, and make the buffer pointer "const". * gnutls.h: Update declarations. * process.c (read_process_output): Use ssize_t, to match. (send_process): Likewise. 2011-04-09 Chong Yidong * image.c (Fimagemagick_types): Doc fix, and comment cleanup. 2011-04-09 Chong Yidong * ftfont.c (get_adstyle_property, ftfont_pattern_entity): Use unsigned char, to match FcChar8 type definition. * xterm.c (handle_one_xevent): * xmenu.c (create_and_show_popup_menu): * xselect.c (x_decline_selection_request) (x_reply_selection_request): Avoid type-punned deref of X events. 2011-04-09 Eli Zaretskii Fix some uses of `int' instead of EMACS_INT. * search.c (string_match_1, fast_string_match) (fast_c_string_match_ignore_case, fast_string_match_ignore_case) (scan_buffer, find_next_newline_no_quit) (find_before_next_newline, search_command, Freplace_match) (Fmatch_data): Make some `int' variables be EMACS_INT. * xdisp.c (display_count_lines): 3rd argument and return value now EMACS_INT. All callers changed. (pint2hrstr): Last argument is now EMACS_INT. * coding.c (detect_coding_utf_8, detect_coding_emacs_mule) (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5) (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8) (decode_coding_utf_16, decode_coding_emacs_mule) (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5) (decode_coding_ccl, decode_coding_charset) : Declare EMACS_INT.

(ASSURE_DESTINATION): Declare more_bytes EMACS_INT. (encode_invocation_designation): Last argument P_NCHARS is now EMACS_INT. (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT. (produce_chars): from_nchars and to_nchars are now EMACS_INT. * coding.h (struct coding_system) : Declare EMACS_INT. All users changed. * ccl.c (Fccl_execute_on_string): Declare some variables EMACS_INT. 2011-04-08 Samuel Thibault (tiny change) * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450). 2011-03-19 Christoph Scholtes * process.c (Fformat_network_address): Doc fix. 2011-04-08 T.V. Raman (tiny change) * xml.c (parse_region): Avoid creating spurious whiespace nodes. 2011-04-08 Chong Yidong * keyboard.c (read_char): Call Lisp function help-form-show, instead of using internal_with_output_to_temp_buffer. (Qhelp_form_show): New var. (syms_of_keyboard): Use DEFSYM macro. * print.c (internal_with_output_to_temp_buffer): Function deleted. * lisp.h (internal_with_output_to_temp_buffer): Remove prototype. 2011-04-06 Chong Yidong * process.c (Flist_processes): Removed to Lisp. (list_processes_1): Deleted. 2011-04-06 Eli Zaretskii * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements. * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs. 2011-04-06 Paul Eggert Fix more problems found by GCC 4.6.0's static checks. * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats. * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats. * lisp.h (message, message_nolog, fatal): Mark as printf-like. * xdisp.c (vmessage): Mark as a printf-like function. * term.c (vfatal, maybe_fatal): Mark as printf-like functions. * sound.c (sound_warning): Don't crash if arg contains a printf format. * image.c (tiff_error_handler, tiff_warning_handler): Mark as printf-like functions. (tiff_load): Add casts to remove these marks before passing them to system-supplied API. * eval.c (Fsignal): Remove excess argument to 'fatal'. * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int. This avoids several warnings with gcc -Wstrict-overflow. (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code directly, rather than having caller test rule sign. This avoids some unnecessary tests. * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro. (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This affects only one use, in DECODE_COMPOSITION_RULE, which is changed. * xfont.c (xfont_text_extents): Remove var that was set but not used. (xfont_open): Avoid unnecessary tests. * composite.c (composition_gstring_put_cache): Use unsigned integer. * composite.h, composite.c (composition_gstring_put_cache): Use EMACS_INT, not int, for length. * composite.h (COMPOSITION_DECODE_REFS): New macro, breaking out part of COMPOSITION_DECODE_RULE. (COMPOSITION_DECODE_RULE): Use it. * composite.c (get_composition_id): Remove unused local vars, by using the new macro. * textprop.c (set_text_properties_1): Change while to do-while, since the condition is always true at first. * intervals.c (graft_intervals_into_buffer): Mark var as used. (interval_deletion_adjustment): Return unsigned value. All uses changed. * process.c (list_processes_1, create_pty, read_process_output): (exec_sentinel): Remove vars that were set but not used.

(read_process_output): Simplify nbytes computation if buffered. * bytecode.c (exec_byte_code): Rename local to avoid shadowing. * syntax.c (scan_words): Remove var that was set but not used. (update_syntax_table): Use unsigned instead of int. * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs. (lisp_file_lexically_bound_p, read1): Use unsigned instead of int. (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop. * print.c (print_error_message): Avoid int overflow. * font.c (font_list_entities): Redo for clarity, so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX. * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.

(sxhash): Redo loop for clarity and to avoid wraparound warning. * eval.c (funcall_lambda): Rename local to avoid shadowing. * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int. Otherwise, GCC 4.6.0 optimizes the loop check away since the check can always succeed if overflow has undefined behavior. * search.c (boyer_moore, wordify): Remove vars set but not used. (wordify): Omit three unnecessary tests. * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column. All callers changed. This avoids the need for an unused var. * casefiddle.c (casify_region): Remove var that is set but not used. * dired.c (file_name_completion): Remove var that is set but not used. * fileio.c (Finsert_file_contents): Make EOF condition clearer. * fileio.c (Finsert_file_contents): Avoid signed integer overflow. (Finsert_file_contents): Remove unnecessary code checking fd. * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes. Check for integer overflow on size calculations. * buffer.c (Fprevious_overlay_change): Remove var that is set but not used. * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt): Remove vars that are set but not used. (timer_check_2): Don't assume timer-list and idle-timer-list are lists. (timer_check_2): Mark vars as initialized. * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized. * image.c (lookup_image): Remove var that is set but not used. (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable. * fontset.c (Finternal_char_font, Ffontset_info): Remove vars that are set but not used. * xfns.c (make_invisible_cursor): Don't return garbage if XCreateBitmapFromData fails (Bug#8410). * xselect.c (x_get_local_selection, x_handle_property_notify): Remove vars that are set but not used. * xfns.c (x_create_tip_frame): Remove var that is set but not used.

Replace 2 copies of readlink code with 1 gnulib version (Bug#8401). The gnulib version avoids calling malloc in the usual case, and on 64-bit hosts doesn't have some arbitrary 32-bit limits. * fileio.c (Ffile_symlink_p): Use emacs_readlink. * filelock.c (current_lock_owner): Likewise. * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function. * sysdep.c: Include allocator.h, careadlinkat.h. (emacs_no_realloc_allocator): New static constant. (emacs_readlink): New function. * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on ../lib/careadlinkat.h. 2011-04-04 Stefan Monnier * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the first non-nil return value). 2011-04-03 Jan Djärv * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6 if not defined (Bug#8403). 2011-04-02 Juanma Barranquero * xdisp.c (display_count_lines): Remove parameter `start', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed. (get_char_face_and_encoding): Remove parameter `multibyte_p', unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed. (fill_stretch_glyph_string): Remove parameters `row' and `area', unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk and thereabouts. All callers changed. (get_per_char_metric): Remove parameter `f', unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed. 2011-04-02 Jim Meyering do not dereference NULL upon failed strdup * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup. (ns_get_family): Likewise. 2011-04-02 Juanma Barranquero * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment. 2011-04-02 Jan Djärv * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or later (Bug#8403). 2011-04-01 Stefan Monnier Add lexical binding. * window.c (Ftemp_output_buffer_show): New fun. (Fsave_window_excursion): * print.c (Fwith_output_to_temp_buffer): Move to subr.el. * lread.c (lisp_file_lexically_bound_p): New function. (Fload): Bind Qlexical_binding. (readevalloop): Remove `evalfun' arg. Bind Qinternal_interpreter_environment. (Feval_buffer): Bind Qlexical_binding. (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard): Mark as dynamic. (syms_of_lread): Declare `lexical-binding'. * lisp.h (struct Lisp_Symbol): New field `declared_special'. * keyboard.c (eval_dyn): New fun. (menu_item_eval_property): Use it. * image.c (parse_image_spec): Use Ffunctionp. * fns.c (concat, mapcar1): Accept byte-code-functions. * eval.c (Fsetq): Handle lexical vars. (Fdefun, Fdefmacro, Ffunction): Make closures when needed. (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic. (FletX, Flet): Obey lexical binding. (Fcommandp): Handle closures. (Feval): New `lexical' arg. (eval_sub): New function extracted from Feval. Use it almost everywhere where Feval was used. Look up vars in lexical env. Handle closures. (Ffunctionp): Move from subr.el. (Ffuncall): Handle closures. (apply_lambda): Remove `eval_flags'. (funcall_lambda): Handle closures and new byte-code-functions. (Fspecial_variable_p): New function.

Add new byte-codes. * buffer.c (defvar_per_buffer): Set new `declared_special' field. * alloc.c (Fmake_symbol): Init new `declared_special' field. 2011-03-31 Juanma Barranquero * xdisp.c (redisplay_internal): Fix prototype. 2011-03-31 Eli Zaretskii * xdisp.c (SCROLL_LIMIT): New macro. (try_scrolling): Use it when setting scroll_limit. Limit scrolling to 100 screen lines. (redisplay_window): Even when falling back on "recentering", position point in the window according to scroll-conservatively, scroll-margin, and scroll-*-aggressively variables. (Bug#6671) (try_scrolling): When point is above the window, allow searching as far as scroll_max, or one screenful, to compute vertical distance from PT to the scroll margin position. This prevents try_scrolling from unnecessarily failing when scroll-conservatively is set to a value slightly larger than the window height. Clean up the case of PT below the margin at bottom of window: scroll_max can no longer be INT_MAX. When aggressive scrolling is in use, don't let point enter the opposite scroll margin as result of the scroll. (syms_of_xdisp) : Document the threshold of 100 lines for never-recentering scrolling. 2011-03-31 Juanma Barranquero * dispextern.h (move_it_by_lines): * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused since 2000-12-29T14:24:09Z!gerd@gnu.org.

(redisplay_internal): Remove parameter `preserve_echo_area', unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed. * indent.c (Fvertical_motion): * window.c (window_scroll_pixel_based, Frecenter): Don't pass `need_y_p' to `move_it_by_lines'. 2011-03-30 Stefan Monnier * eval.c (struct backtrace): Don't cheat with negative numbers, but do steal a few bits to be more compact. (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace): Remove unneeded casts. * bytecode.c (Fbyte_code): CAR and CDR can GC. 2011-03-30 Zachary Kanfer (tiny change) * keyboard.c (Fexecute_extended_command): Do log the "suggest key binding" message (bug#7967). 2011-03-30 Paul Eggert Fix more problems found by GCC 4.6.0's static checks. * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]: Remove unused local var. * editfns.c (Fmessage_box): Remove unused local var. * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs): (note_mode_line_or_margin_highlight, note_mouse_highlight): Omit unused local vars. * window.c (shrink_windows): Omit unused local var. * menu.c (digest_single_submenu): Omit unused local var. * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]: Omit unused local var. * keyboard.c (parse_modifiers_uncached, parse_modifiers): Don't assume string length fits in int.

(Fbacktrace_frame): Don't assume nframes fits in int. * syntax.c (scan_sexps_forward): Avoid pointer wraparound. * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow concerns. * term.c (produce_glyphless_glyph): Remove unnecessary test. * cm.c (calccost): Turn while-do into do-while, for clarity. * keyboard.c (syms_of_keyboard): Use the same style as later in this function when indexing through an array. This also works around GCC bug 48267. * image.c (tiff_load): Fix off-by-one image count (Bug#8336). * xselect.c (x_check_property_data): Return correct size (Bug#8335). * chartab.c (sub_char_table_ref_and_range): Redo for slight efficiency gain, and to bypass a gcc -Wstrict-overflow warning. * keyboard.c, keyboard.h (num_input_events): Now size_t. This avoids undefined behavior on integer overflow, and is a bit more convenient anyway since it is compared to a size_t variable. Variadic C functions now count arguments with size_t, not int. This avoids an unnecessary limitation on 64-bit machines, which caused (substring ...) to crash on large vectors (Bug#8344). * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int. (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise. All variadic functions and their callers changed accordingly. (struct gcpro.nvars): Now size_t, not int.

All callers changed. * alloc.c (garbage_collect): Don't assume stack size fits in int. (stack_copy_size): Now size_t, not int. (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0. 2011-03-28 Juanma Barranquero * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end', unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

(tparm): Make 1st arg a const pointer in decl. Put it at top level. (tparam): Adjust signature to match interface in tparam.h; this removes some undefined behavior. Check that outstring and len are zero, which they always are with Emacs. * tparam.h (PC, BC, UP): New extern decls. * xftfont.c (xftfont_shape): Now static, and defined only if needed.

Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out. * lisp.h (child_setup): Now NO_RETURN unless DOS_NT. This should get cleaned up, so that child_setup has the same signature on all platforms. * callproc.c (call_process_cleanup): Now static. (relocate_fd): Rename locals to avoid shadowing. 2011-03-22 Chong Yidong * xterm.c (x_clear_frame): Remove XClearWindow call.

New file unexec.h, the (simple) interface for unexec (Bug#8267). * unexec.h: New file. * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o): (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o): Depend on unexec.h. * emacs.c [!defined CANNOT_DUMP]: Include unexec.h. * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c: * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

All uses changed. * dired.c (directory_files_internal, file_name_completion): Rename locals to avoid shadowing. Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254). An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in dired.c's scmp function, had undefined behavior. * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP): (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ... * buffer.h: ... to here, because these macros use current_buffer, and the new implementation with inline functions needs to have current_buffer in scope now, rather than later when the macros are used. (downcase, upcase1): New static inline functions. (DOWNCASE, UPCASE1): Reimplement using these functions. This avoids undefined behavior in expressions like DOWNCASE (x) == DOWNCASE (y), which previously suffered from race conditions in accessing the global variables case_temp1 and case_temp2. * casetab.c (case_temp1, case_temp2): Remove; no longer needed. * lisp.h (case_temp1, case_temp2): Remove their decls. * character.h (ASCII_CHAR_P): Move from here ... * lisp.h: ... to here, so that the inline functions mentioned above can use them. * dired.c (directory_files_internal_unwind): Now static. * fileio.c (file_name_as_directory, directory_file_name): (barf_or_query_if_file_exists, auto_save_error, auto_save_1): Now static.
