+
+ * msdos.c (vga_installed): New function, code moved from
+ dos_set_window_size.
+ (Qbar, Qcursor_type, outside_cursor): New variables.
+ (syms_of_msdos): Intern and staticpro them.
+ (dos_ttraw) [__DJGPP__ >= 2, !HAVE_X_WINDOWS]: Save the cursor
+ shape used outside Emacs when called for the first time.
+ (dos_ttcooked) [__DJGPP__ >= 2, !HAVE_X_WINDOWS]: Restore the
+ cursor shape used outside Emacs.
+ (msdos_set_cursor_shape, IT_set_cursor_type): New functions.
+ (IT_frame_up_to_date): Call IT_set_cursor_type, in case the cursor
+ type has changed.
+ (IT_set_frame_parameters): Call IT_set_cursor_type if the frame
+ parameters specify the cursor. Make qreverse a global
+ variable (renamed to Qreverse).
+
+2000-03-09 Gerd Moellmann <gerd@gnu.org>
+
+ * fns.c (Fy_or_n_p): Cancel busy-cursor.
+
+2000-03-08 Stefan Monnier <monnier@cs.yale.edu>
+
+ This is a big redesign of failure-stack and register handling, prompted
+ by bugs revealed when trying to add shy-groups. Overall, what happened
+ is that loops are now structured a little differently, groups can be
+ shy and the code is a little simpler.
+
+ * regex.h: Update the copyright.
+ (RE_SHY_GROUPS): New value.
+ (RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
+ (RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.
+
+ * regex.c (enum re_opcode_t): Remove jump_past_alt,
+ maybe_pop_jump, push_dummy_failure and dumy_failure_jump. Add
+ on_failure_jump_(exclusive, loop and smart). Also fix the comment
+ for (start|stop)_memory since they now only take one argument (the
+ second has becomes unnecessary).
+ (print_partial_compiled_pattern): Adjust for changes in
+ re_opcode_t.
+ (print_compiled_pattern): Use %ld to printf long ints and flush to
+ make debugging a little easier.
+ (union fail_stack_elt): Make the integer unsigned.
+ (struct fail_stack_type): Add a `frame' element.
+ (INIT_FAIL_STACK): Init `frame' as well.
+ (POP_PATTERN_OP): New macro for re_compile_fastmap.
+ (DEBUG_PUSH, DEBUG_POP): Remove.
+ (NUM_REG_ITEMS): Remove.
+ (NUM_NONREG_ITEMS): Adjust.
+ (FAILURE_PAT, FAILURE_STR, NEXT_FAILURE_HANDLE)
+ (TOP_FAILURE_HANDLE): New macros for the cycle detection.
+ (ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT).
+ (PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP): New
+ macros.
+ (PUSH_FAILURE_POINT): Don't push registers any more. The pattern
+ address pushed is not the destination of the jump but the source
+ of it instead.
+ (NUM_FAILURE_ITEMS): Remove.
+ (POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop
+ registers before the actual failure point). Don't hardcode any
+ meaning for str==NULL anymore.
+ (union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE)
+ (MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED):
+ Remove.
+ (REG_UNSET_VALUE): Use NULL (why not?).
+ (compile_range): Remove declaration since it doesn't exist.
+ (struct compile_stack_elt_t): Remove inner_group_offset.
+ (old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove.
+ (regex_grow_registers): Remove dead code.
+ (FIXUP_ALT_JUMP): New macro.
+ (regex_compile): Add shy-groups Change loops to use
+ on_failure_jump_smart&jump instead of
+ on_failure_jump&maybe_pop_jump. Change + loops to eliminate the
+ initial (dummy_failure_)jump. Remove c1_base (looks like unused
+ variable to me). Use `jump' instead of `jump_past_alt' and don't
+ bother with push_dummy_failure in alternatives since it is now
+ unnecessary. Use FIXUP_ALT_JUMP. Eliminate a useless `#ifdef
+ emacs' for (re)allocating the stack.
+ (re_compile_fastmap): Remove dead variables i and num_regs. Exit
+ from loop when bufp->can_be_null rather than jumping to `done'.
+ Avoid jumping backwards so as to ensure termination. Use
+ PATTERN_STACK_EMPTY and POP_PATTERN_OP. Improved handling of
+ backreferences. Remove dead code in handling of `anychar'.
+ (skip_noops, mutually_exclusive_p): New functions taken from the
+ handling of `maybe_pop_jump' in re_match_2_internal. Slightly
+ improve mutually_exclusive_p to handle ".+\n".
+ (lowest_active_reg, highest_active_reg,
+ NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
+ (re_match_2_internal): Use %p instead of 0x%x when printf'ing
+ ptrs. Don't SET_REGS_MATCHED anymore. Remove many dead
+ variables. Push register (in `start_memory') on the stack rather
+ than storing it in old_reg(start|end). Remove the cycle detection
+ from `stop_memory', replaced by the use of on_failure_jump_loop
+ for greedy loops. Add code for the new on_failure_jump_<foo>.
+ Remove ad-hoc code in `on_failure_jump' to push more registers in
+ the case of a loop. Take out code from `maybe_pop_jump' into
+ separate functions and adapt it to the semantics of
+ `on_failure_jump_smart'. Remove jump_past_alt, dummy_failure_jump
+ and push_dummy_failure. Remove dummy_failure handling and
+ handling of `failures to jump to on_failure_jump' (this last one
+ was already dead code, it seems).
+ (group_match_null_string_p, alt_match_null_string_p)
+ (common_op_match_null_string_p): Remove.
+
+2000-03-08 Dave Love <fx@gnu.org>
+
+ * config.in: Don't depend on __STDC__ for volatile.
+ Add POINTER_TYPE, PTR, PROTOTYPES.
+
+ * hftctl.c, strftime.c: Use PROTOTYPES.
+ * eval.c (find_handler_clause): Likewise.
+
+ * mem-limits.h: Use POINTER_TYPE.
+
+ * lisp.h (P_): Define based on PROTOTYPES, not __STDC__.
+ (memory_warnings): Declare using POINTER_TYPE.
+
+2000-03-08 Gerd Moellmann <gerd@gnu.org>
+
+ * xfns.c (x_set_cursor_type): If ARG is nil, give frame no cursor.
+
+ * xdisp.c (display_echo_area): Temporarily inhibit garbage
+ collection.
+
+ * xfns.c: Remove obsolete code in #if 0.
+ (Fx_focus_frame): New function.
+
+2000-03-07 Gerd Moellmann <gerd@gnu.org>
+
+ * doc.c (Fdocumentation_property): If value is not a string,
+ and doesn't refer to etc/DOC, evaluate it to obtain a string.
+
+ * xterm.c (x_connection_closed) [USE_X_TOOLKIT]: Don't try to
+ close the display with XtCloseDisplay. This caused a bus error
+ on OpenWindows.
+
+ * minibuf.c (Fminibuffer_complete): Move point to ZV when input is
+ complete but not unique.
+
+2000-03-06 Gerd Moellmann <gerd@gnu.org>
+
+ * process.c (send_process): Remove local variable `procname' that
+ might become invalid when a GC happens. Instead, access the
+ process name slot directly.
+
+ * xfns.c (x_set_menu_bar_lines_1): Adjust window's orig_top and
+ orig_height if set.
+
+ * frame.c (set_menu_bar_lines_1): Adjust window's orig_top and
+ orig_height if set.
+
+2000-03-06 Eli Zaretskii <eliz@is.elta.co.il>
+
+ * msdos.c (IT_note_mouse_highlight): Return immediately if frame's
+ glyph matrices have been freed.
+
2000-03-05 Gerd Moellmann <gerd@gnu.org>
* Makefile.in (tags): Include ../lwlib/TAGS in TAGS.
+ (bootstrap-temacs): Set LC_ALL to C like for temacs.
* xfns.c (QCdata): Moved to xdisp.c.
FRAME_INTERNAL_BORDER_WIDTH.
* xdisp.c (try_window_id): Recompute unchanged information if
- it is invalid.
+ it is obviously invalid.
* xterm.c (x_term_init): Create a colormap if not using the
default visual.
