      (display_menu_bar): If the Lisp string to be displayed in the
      menu-bar or tool-bar window is multibyte, tell the display
      engine to treat it as multibyte, instead of relying on the
      initial determination by init_iterator (which is based on the
      multibyteness of the current buffer).  (Bug#37385)

      Fix two mouse drag and drop issues (Bug#28620, Bug#36269) · 5ec3f705
      Martin Rudalics authored
      Allow 'mouse-drag-and-drop-region' to move/copy text from one
      frame to another (Bug#28620).  Prevent mouse avoidance mode from
      interfering with 'mouse-drag-and-drop-region' (Bug#36269).

      when 'track-mouse' equals 'dropping'.

      check whether mouse is tracked, some_mouse_moved does it now.
      (track_mouse): Rename variable from do_mouse_tracking.  Adjust
      all users.  In doc-string explain meanings of special values
      'dragging' and 'dropping'.
      * src/nsterm.m (ns_mouse_position): During drag and drop
      consider last mouse frame only when there is no currently
      focused frame.

      drag and drop operation.

      Make message_to_stderr do one single fwrite · 630e01a7
      Lars Ingebrigtsen authored
      * src/xdisp.c (message_to_stderr): When running as a batch
      process, the output from `message' goes to stderr, and has a
      newline appended.  Rewrite the code so that only one fwrite is
      performed to enable messages that are shorter than PIPE_BUF
      (usually 4096 on modern operating systems) are written out as one
      chunk, as this will ensure that the messages are not interleaved
      with messages from other processes that are writing at the same
      time.  This does not affect other stderr outputs, just the ones
      from `message'.

      Remove fixnum restriction on some display vars · dfed333b
      Paul Eggert authored
      This is a minor patch to remove some fixnum restrictions.
      Many more such patches are needed, but one thing at a time.
      * doc/emacs/custom.texi (Examining): Update fill-column example.
      * src/buffer.c (fill-column, left-margin, tab-width)
      (buffer-saved-size, left-margin-width, right-margin-width)
      (left-fringe-width, right-fringe-width, scroll-bar-width)
      (scroll-bar-height, buffer-display-count):
      Allow any integer; do not restrict to fixnums.
      * src/character.h (SANE_TAB_WIDTH): Do not assume tab_width
      is a nonnegative fixnum.
      (sanitize_tab_width): Take a Lisp_Object integer, not an
      EMACS_INT.  Only use changed.
      * src/data.c (store_symval_forwarding): Remove unnecessary
      SYMBOLP since the predicate (e.g., Qintegerp) is always a
      symbol (leave the test in as an eassert).  Avoid assignments
      inside if-conditions.
      * src/fileio.c (Fdo_auto_save): Do not assume
      buffer-saved-size is a fixnum.  Avoid undefined behavior
      on EMACS_INT overflow by multiplying a fixnum by at most 4,
      not by at most 13.
      * src/window.c (set_window_buffer): When buffer-display-count
      is too large for a fixnum, make it a bignum.
      * src/xdisp.c (FILL_COLUMN_INDICATOR_NEEDED): Remove macro, ...
      (fill_column_indicator_column): ... replacing with this new function.
      All uses changed.  The function is a bit pickier, to prevent
      problems with non-character fixnums and columns out of range
      for int, and to remove the assumption that integers are in
      fixnum range.
      (append_space_for_newline, extend_face_to_end_of_line):
      Avoid undefined behavior with signed integer overflow.
      Simplify.

      Remove display member of glyph_string · 6bfc5fc6
      Alexander Gramiak authored
      This member has little value even on X, and it leaks internal backend
      details to the glyph_string struct.
      
      * src/dispextern.h (glyph_string): Remove X display member.
      
      * src/xdisp.c (init_glyph_string): Remove initialization of display.
      
      * src/xfont.c (xfont_draw):
      * src/xterm.c: Use FRAME_X_DISPLAY (s->f) instead of display member.

      Pacify GCC 9.1 · 504f8e55
      Paul Eggert authored
      * src/intervals.c (set_intervals_multibyte_1): Omit unused temps.
      * src/xdisp.c (display_mode_element): Use !NILP instead of
      STRINGP.  This convinces GCC we’re not dereferencing a
      possibly-null pointer, and should be a bit faster anyway.
