157 effects, one visible being that the cursor of a frame created with
158 C-x 5 2 or switched to with a window manager key binding like

217 padding glyph not fitting on line as whole character not
220 * xterm.c (x_produce_glyphs): Don't xassert `it->descent > 0';
221 this isn't true for images with `:ascent 100'.

2072 (realize_face): Argument changed. Caller changed. Remove face
2073 with the arg former_face_id in advance. Load font for the new
2075 (realize_x_face): Argument changed. Caller changed. For a
2076 multibyte character, share fontset with base_face. For a single
2077 byte character, make a new realized fontset. Don't load a font
2079 (realize_tty_face): Argument changed. Caller changed.
2080 (compute_char_face): Call FACE_FOR_CHAR, not FACE_FOR_CHARSET.
2081 (face_at_buffer_position): Don't check multibyte_p for returning

2100 character, convert it to a unibyte character.
2101 (struct glyph_string): Delete member `charset'.
2102 (x_set_mouse_face_gc): Call FACE_FOR_CHAR to get face_id. Handle
2103 the case that per char metric is not available correctly.

2126 (try_window_reusing_current_matrix): Don't call scroll run
2127 function if run's current and desired position are the same;
2128 this prevents cursor flickering.
2130 2000-03-19 Stefan Monnier <monnier@cs.yale.edu>
2132 * regex.h (RE_TRANSLATE. RE_TRANSLATE_P): Moved to regex.c.

2155 * xfns.c (select_visual): Don't set dpyinfo->n_planes to the
2156 number of bits per RGB because it's everywhere used as the depth

2182 2000-03-15 Stefan Monnier <monnier@cs.yale.edu>
2184 * regex.c (re_match_2): Fix string shortening (to fit `stop') to
2185 make sure POINTER_TO_OFFSET gives the same value before and after
2186 PREFETCH. Use `dfail' to guarantee "atomic" matching.
2187 (PTR_TO_OFFSET): Use POINTER_TO_OFFSET.
2188 (debug): Now only active if > 0 rather than if != 0.
2189 (DEBUG_*): Update for the new meaning of `debug'.

2248 2000-03-13 Stefan Monnier <monnier@cs.yale.edu>
2250 * regex.c: Declare a new type `re_char' used throughout the code
2251 for the string char type. It's `const unsigned char' to match the
2252 rest of Emacs. Consistently make sure all pointers to strings use
2253 it and make sure all pointers into the pattern use `unsigned
2255 (re_match_2_internal): Use `PREFETCH+STRING_CHAR' instead of
2256 GET_CHAR_AFTER_2. Also merge wordbound and notwordbound to reduce
2259 * charset.h (GET_CHAR_AFTER_2): Remove.
2260 (GET_CHAR_BEFORE_2): Use unsigned chars, like everywhere else.
2262 2000-03-12 Ken Raeburn <raeburn@gnu.org>
2264 * Makefile.in (temacs): Evaluate ALL_LDFLAGS into a temporary
2265 variable before the invocation of YMF_PASS_LDFLAGS, in case both

2268 2000-03-12 Dave Love <fx@gnu.org>
2270 * unexelf.c: Restore changes of 1999-10-19.
2271 (unexec): Don't adjust bss for sbss type SHT_PROGBITS; otherwise
2272 fix its type and alignment; copy it from current process.
2274 2000-03-12 Gerd Moellmann <gerd@gnu.org>
2276 * atimer.c (cancel_atimer): Break out of the loop as soon as timer

2302 variable (renamed to Qreverse).
2304 2000-03-09 Gerd Moellmann <gerd@gnu.org>
2306 * fns.c (Fy_or_n_p): Cancel busy-cursor.
2308 2000-03-08 Stefan Monnier <monnier@cs.yale.edu>
2310 This is a big redesign of failure-stack and register handling, prompted
2311 by bugs revealed when trying to add shy-groups. Overall, what happened
2312 is that loops are now structured a little differently, groups can be
2313 shy and the code is a little simpler.
2315 * regex.h: Update the copyright.
2316 (RE_SHY_GROUPS): New value.
2317 (RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
2318 (RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.
2320 * regex.c (enum re_opcode_t): Remove jump_past_alt,
2321 maybe_pop_jump, push_dummy_failure and dumy_failure_jump. Add
2322 on_failure_jump_(exclusive, loop and smart). Also fix the comment
2323 for (start|stop)_memory since they now only take one argument (the
2324 second has becomes unnecessary).
2325 (print_partial_compiled_pattern): Adjust for changes in
2327 (print_compiled_pattern): Use %ld to printf long ints and flush to
2328 make debugging a little easier.
2329 (union fail_stack_elt): Make the integer unsigned.
2330 (struct fail_stack_type): Add a `frame' element.
2331 (INIT_FAIL_STACK): Init `frame' as well.

2337 (TOP_FAILURE_HANDLE): New macros for the cycle detection.
2338 (ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT).
2339 (PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP): New
2341 (PUSH_FAILURE_POINT): Don't push registers any more. The pattern
2342 address pushed is not the destination of the jump but the source
2344 (NUM_FAILURE_ITEMS): Remove.
2345 (POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop
2346 registers before the actual failure point). Don't hardcode any
2347 meaning for str==NULL anymore.
2348 (union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE)
2349 (MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED):
2351 (REG_UNSET_VALUE): Use NULL (why not?).
2352 (compile_range): Remove declaration since it doesn't exist.
2353 (struct compile_stack_elt_t): Remove inner_group_offset.
2354 (old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove.
2355 (regex_grow_registers): Remove dead code.
2356 (FIXUP_ALT_JUMP): New macro.
2357 (regex_compile): Add shy-groups Change loops to use
2358 on_failure_jump_smart&jump instead of
2359 on_failure_jump&maybe_pop_jump. Change + loops to eliminate the
2360 initial (dummy_failure_)jump. Remove c1_base (looks like unused
2361 variable to me). Use `jump' instead of `jump_past_alt' and don't
2362 bother with push_dummy_failure in alternatives since it is now
2363 unnecessary. Use FIXUP_ALT_JUMP. Eliminate a useless `#ifdef
2364 emacs' for (re)allocating the stack.
2365 (re_compile_fastmap): Remove dead variables i and num_regs. Exit
2366 from loop when bufp->can_be_null rather than jumping to `done'.
2367 Avoid jumping backwards so as to ensure termination. Use
2368 PATTERN_STACK_EMPTY and POP_PATTERN_OP. Improved handling of
2369 backreferences. Remove dead code in handling of `anychar'.
2370 (skip_noops, mutually_exclusive_p): New functions taken from the
2371 handling of `maybe_pop_jump' in re_match_2_internal. Slightly
2372 improve mutually_exclusive_p to handle ".+\n".
2373 (lowest_active_reg, highest_active_reg,
2374 NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
2375 (re_match_2_internal): Use %p instead of 0x%x when printf'ing
2376 ptrs. Don't SET_REGS_MATCHED anymore. Remove many dead
2377 variables. Push register (in `start_memory') on the stack rather
2378 than storing it in old_reg(start|end). Remove the cycle detection
2379 from `stop_memory', replaced by the use of on_failure_jump_loop
2380 for greedy loops. Add code for the new on_failure_jump_<foo>.
2381 Remove ad-hoc code in `on_failure_jump' to push more registers in
2382 the case of a loop. Take out code from `maybe_pop_jump' into
2383 separate functions and adapt it to the semantics of
2384 `on_failure_jump_smart'. Remove jump_past_alt, dummy_failure_jump
2385 and push_dummy_failure. Remove dummy_failure handling and
2386 handling of `failures to jump to on_failure_jump' (this last one
2387 was already dead code, it seems).
2388 (group_match_null_string_p, alt_match_null_string_p)
2389 (common_op_match_null_string_p): Remove.
2391 2000-03-08 Dave Love <fx@gnu.org>

2424 (detect_coding_utf_16): New function
2425 (detect_coding_mask): When priorities are specified, skip any
2426 categories that have `nil' coding-system. Fix bug of returning
2427 wrong mask when PRIORITIES is specified and detect_coding_XXX()
2428 returns a mask not set in PRIORITIES.
2429 (detect_eol_type_in_2_octet_form): New function.
2430 (detect_eol): selects detect_eol_type_XXX to call according to

2458 2000-03-06 Gerd Moellmann <gerd@gnu.org>
2460 * process.c (send_process): Remove local variable `procname' that
2461 might become invalid when a GC happens. Instead, access the
2462 process name slot directly.
2464 * xfns.c (x_set_menu_bar_lines_1): Adjust window's orig_top and
2467 * frame.c (set_menu_bar_lines_1): Adjust window's orig_top and
