      Fix minor problems found by static checking. · ad6042bb
      Paul Eggert authored
      * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
      (elsz): Now a signed constant, not a size_t var.  We prefer signed
      types to unsigned, to avoid integer comparison confusion.  Without
      this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
      "cannot optimize loop, the loop counter may overflow", a symptom
      of the confusion.

      Support bidi reordering of overlay and display strings. · 0bb23927
      Eli Zaretskii authored
      Fix bugs #7616, #8133, #8867.
       src/xdisp.c (compute_display_string_pos)
       (compute_display_string_end): Accept additional argument STRING.
       (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
       (reseat_to_string): Initialize bidi_it->string.s and
       (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
       NULL (avoids a crash in bidi_paragraph_init).  Initialize
       (init_iterator): Call bidi_init_it only of a valid
       buffer position was specified.  Initialize paragraph_embedding to
       (reseat_to_string): Initialize the bidi iterator.
       (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.)
       (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
       (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).
       (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.
       (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.
       (set_iterator_to_next): Support bidi reordering of C strings and
       Lisp strings.
       (next_element_from_string): Support bidi reordering of Lisp
       (handle_stop_backwards): Support Lisp strings as well.
       (display_string): Support display of R2L glyph rows.  Use
       IT_STRING_CHARPOS when displaying from a Lisp string.
       (init_iterator): Don't initialize it->bidi_p for strings
       (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
       (face_before_or_after_it_pos): Support bidi iteration.
       (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
       (tool_bar_lines_needed, redisplay_tool_bar)
       (display_menu_bar): Force left-to-right direction.  Add a FIXME
       comment for making that be controlled by a user option.
       (push_it, pop_it): Save and restore the state of the
       bidi iterator.  Save and restore the bidi_p flag.
       (pop_it): Iterate out of display property for string iteration as
       (iterate_out_of_display_property): Support iteration over strings.
       (handle_single_display_spec): Set up it->bidi_it for iteration
       over a display string, and call bidi_init_it.
       (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
       (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.
       (push_it, pop_it): Save and restore paragraph_embedding member.
       (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_end): Fix handling the case of C string.
       (push_it, pop_it): Save and restore from_disp_prop_p.
       (handle_single_display_spec, push_display_prop): Set the
       from_disp_prop_p flag.
       (get_overlay_strings_1): Reset the from_disp_prop_p flag.
       (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
       (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.
       (reseat_1): Call bidi_init_it to resync the bidi
       iterator with IT's position.  (Bug#7616)
       (find_row_edges): If ROW->start.pos gives position
       smaller than min_pos, use it as ROW->minpos.  (Bug#7616)
       (handle_stop, back_to_previous_visible_line_start, reseat_1):
       Reset the from_disp_prop_p flag.
       (SAVE_IT, RESTORE_IT): New macros.
       (pos_visible_p, face_before_or_after_it_pos)
       (move_it_in_display_line_to, move_it_in_display_line)
       (move_it_to, move_it_vertically_backward, move_it_by_lines)
       (try_scrolling, redisplay_window, display_line): Use them when
       saving a temporary copy of the iterator and restoring it back.
       (back_to_previous_visible_line_start, reseat_1)
       (init_iterator): Empty the bidi cache "stack".
       (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.
       (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
       (pos_visible_p): Support positions in bidi-reordered lines.  Save
       and restore bidi cache.
       src/bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
       (bidi_paragraph_info): Delete unused struct.
       (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
       (bidi_cache_start): New variable.

       (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.  Support strings with
       display properties.  Support unibyte strings.  Fix the type of
       `len' according to what STRING_CHAR_AND_LENGTH expects.

       (bidi_initialize): Initialize the bidi cache start stack pointer.
       (bidi_cache_ensure_space): New function, refactored from part of

       (bidi_count_bytes, bidi_char_at_pos): New functions.
