111 example a keystroke event, forces it to do so. This has various
112 effects, one visible being that the cursor of a frame created with
113 C-x 5 2 or switched to with a window manager key binding like

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

2082 function if run's current and desired position are the same;
2083 this prevents cursor flickering.
2085 2000-03-19 Stefan Monnier <monnier@cs.yale.edu>

2137 2000-03-15 Stefan Monnier <monnier@cs.yale.edu>
2139 * regex.c (re_match_2): Fix string shortening (to fit `stop') to
2140 make sure POINTER_TO_OFFSET gives the same value before and after
2141 PREFETCH. Use `dfail' to guarantee "atomic" matching.
2142 (PTR_TO_OFFSET): Use POINTER_TO_OFFSET.
2143 (debug): Now only active if > 0 rather than if != 0.
2144 (DEBUG_*): Update for the new meaning of `debug'.
2145 (print_partial_compiled_pattern): Add missing `succeed' case. Use

2203 2000-03-13 Stefan Monnier <monnier@cs.yale.edu>
2205 * regex.c: Declare a new type `re_char' used throughout the code
2206 for the string char type. It's `const unsigned char' to match the
2207 rest of Emacs. Consistently make sure all pointers to strings use
2208 it and make sure all pointers into the pattern use `unsigned
2210 (re_match_2_internal): Use `PREFETCH+STRING_CHAR' instead of
2211 GET_CHAR_AFTER_2. Also merge wordbound and notwordbound to reduce
2214 * charset.h (GET_CHAR_AFTER_2): Remove.
2215 (GET_CHAR_BEFORE_2): Use unsigned chars, like everywhere else.
2217 2000-03-12 Ken Raeburn <raeburn@gnu.org>
2219 * Makefile.in (temacs): Evaluate ALL_LDFLAGS into a temporary

2223 2000-03-12 Dave Love <fx@gnu.org>
2225 * unexelf.c: Restore changes of 1999-10-19.
2226 (unexec): Don't adjust bss for sbss type SHT_PROGBITS; otherwise
2227 fix its type and alignment; copy it from current process.
2229 2000-03-12 Gerd Moellmann <gerd@gnu.org>
2231 * atimer.c (cancel_atimer): Break out of the loop as soon as timer

2259 2000-03-09 Gerd Moellmann <gerd@gnu.org>
2261 * fns.c (Fy_or_n_p): Cancel busy-cursor.
2263 2000-03-08 Stefan Monnier <monnier@cs.yale.edu>
2265 This is a big redesign of failure-stack and register handling, prompted
2266 by bugs revealed when trying to add shy-groups. Overall, what happened
2267 is that loops are now structured a little differently, groups can be
2268 shy and the code is a little simpler.
2270 * regex.h: Update the copyright.
2271 (RE_SHY_GROUPS): New value.
2272 (RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
2273 (RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.
2275 * regex.c (enum re_opcode_t): Remove jump_past_alt,
2276 maybe_pop_jump, push_dummy_failure and dumy_failure_jump. Add
2277 on_failure_jump_(exclusive, loop and smart). Also fix the comment
2278 for (start|stop)_memory since they now only take one argument (the
2279 second has becomes unnecessary).
2280 (print_partial_compiled_pattern): Adjust for changes in
2282 (print_compiled_pattern): Use %ld to printf long ints and flush to
2283 make debugging a little easier.
2284 (union fail_stack_elt): Make the integer unsigned.
2285 (struct fail_stack_type): Add a `frame' element.
2286 (INIT_FAIL_STACK): Init `frame' as well.
2287 (POP_PATTERN_OP): New macro for re_compile_fastmap.
2288 (DEBUG_PUSH, DEBUG_POP): Remove.
2289 (NUM_REG_ITEMS): Remove.

2292 (TOP_FAILURE_HANDLE): New macros for the cycle detection.
2293 (ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT).
2294 (PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP): New
2296 (PUSH_FAILURE_POINT): Don't push registers any more. The pattern
2297 address pushed is not the destination of the jump but the source
2299 (NUM_FAILURE_ITEMS): Remove.
2300 (POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop
2301 registers before the actual failure point). Don't hardcode any
2302 meaning for str==NULL anymore.
2303 (union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE)
2304 (MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED):
2306 (REG_UNSET_VALUE): Use NULL (why not?).
2307 (compile_range): Remove declaration since it doesn't exist.
2308 (struct compile_stack_elt_t): Remove inner_group_offset.
2309 (old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove.
2310 (regex_grow_registers): Remove dead code.
2311 (FIXUP_ALT_JUMP): New macro.
2312 (regex_compile): Add shy-groups Change loops to use
2313 on_failure_jump_smart&jump instead of
2314 on_failure_jump&maybe_pop_jump. Change + loops to eliminate the
2315 initial (dummy_failure_)jump. Remove c1_base (looks like unused
2316 variable to me). Use `jump' instead of `jump_past_alt' and don't
2317 bother with push_dummy_failure in alternatives since it is now
2318 unnecessary. Use FIXUP_ALT_JUMP. Eliminate a useless `#ifdef
2319 emacs' for (re)allocating the stack.
2320 (re_compile_fastmap): Remove dead variables i and num_regs. Exit
2321 from loop when bufp->can_be_null rather than jumping to `done'.
2322 Avoid jumping backwards so as to ensure termination. Use
2323 PATTERN_STACK_EMPTY and POP_PATTERN_OP. Improved handling of
2324 backreferences. Remove dead code in handling of `anychar'.
2325 (skip_noops, mutually_exclusive_p): New functions taken from the
2326 handling of `maybe_pop_jump' in re_match_2_internal. Slightly
2327 improve mutually_exclusive_p to handle ".+\n".
2328 (lowest_active_reg, highest_active_reg,
2329 NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
2330 (re_match_2_internal): Use %p instead of 0x%x when printf'ing
2331 ptrs. Don't SET_REGS_MATCHED anymore. Remove many dead
2332 variables. Push register (in `start_memory') on the stack rather
2333 than storing it in old_reg(start|end). Remove the cycle detection
2334 from `stop_memory', replaced by the use of on_failure_jump_loop
2335 for greedy loops. Add code for the new on_failure_jump_<foo>.
2336 Remove ad-hoc code in `on_failure_jump' to push more registers in
2337 the case of a loop. Take out code from `maybe_pop_jump' into
2338 separate functions and adapt it to the semantics of
2339 `on_failure_jump_smart'. Remove jump_past_alt, dummy_failure_jump
2340 and push_dummy_failure. Remove dummy_failure handling and
2341 handling of `failures to jump to on_failure_jump' (this last one
2342 was already dead code, it seems).
2343 (group_match_null_string_p, alt_match_null_string_p)
2344 (common_op_match_null_string_p): Remove.
2346 2000-03-08 Dave Love <fx@gnu.org>
2348 * config.in: Don't depend on __STDC__ for volatile.

2380 (detect_coding_mask): When priorities are specified, skip any
2381 categories that have `nil' coding-system. Fix bug of returning
2382 wrong mask when PRIORITIES is specified and detect_coding_XXX()
2383 returns a mask not set in PRIORITIES.
2384 (detect_eol_type_in_2_octet_form): New function.
2385 (detect_eol): selects detect_eol_type_XXX to call according to

2416 might become invalid when a GC happens. Instead, access the
2417 process name slot directly.
2419 * xfns.c (x_set_menu_bar_lines_1): Adjust window's orig_top and
2422 * frame.c (set_menu_bar_lines_1): Adjust window's orig_top and
