      Simplify list creation in C code · 5c2563a5
      Paul Eggert authored
      The main new thing here is that C code can now say
      ‘list (a, b, c, d, e, f)’ instead of
      ‘listn (CONSTYPE_HEAP, 6, a, b, c, d, e, f)’,
      thus relieving callers of the responsibility of counting
      arguments (plus, the code feels more like Lisp).  The old
      list1 ... list5 functions remain, as they’re probably a bit
      faster for small lists.
      * src/alloc.c (cons_listn, pure_listn): New functions.
      (listn): Omit enum argument.
      All callers changed to use either new ‘list’ or ‘pure_list’ macros.

      DEFVAR_INT variables are now intmax_t · e828765d
      Paul Eggert authored
      Formerly they were fixnums, which led to problems when dealing
      with values that might not fit on 32-bit platforms, such as
      string-chars-consed or floats_consed.  64-bit counters should
      be good enough for these (for a while, anyway...).
      While we’re at it, fix some unlikely integer overflow bugs

      In edebug in GUIs, move focus to the selected frame. · 7cfe2dc4
      Alan Mackenzie authored
      Thus when entering edebug, the focus will be moved to the frame with the
      source being debugged, and when its finished, the focus will move back.
      Commands edebug-visit-eval-list (`E') and edebug-bounce-point (`p') have been
      likewise amended.
      
      * src/keyboard.c (readable_events): Handle FOCUS_OUT_EVENT as an invisible
      event.  This prevents input-pending-p returning t when one of these events
      arrives, and thus obviates an instant termination of sit-for when there's no
      "real" event waiting.
      
      * lisp/emacs-lisp/edebug.el (edebug-focus-frame): New function.
      (edebug-default-enter, edebug--display-1, edbug-where, edebug-bounce-point)

      window newly selected by edebug-pop-to-buffer.

      Improve bignum support for system types · d77d01d2
      Paul Eggert authored
      Use bignums when Emacs converts to and from system types like
      off_t for file sizes whose values can exceed fixnum range.
      Formerly, Emacs sometimes generted floats and sometimes ad-hoc
      conses of integers.  Emacs still accepts floats and conses for
      these system types, in case some stray Lisp code is generating
      them, though this usage is obsolescent.

      New focus management interface · 2f6c6820
      Daniel Colascione authored
      focus-in-hook and focus-out-hook don't accurately reflect actual
      user-visible focus states.  Add a new focus interface and mark the old
      one obsolete.
      
      * doc/lispref/frames.texi (Input Focus): Document new focus
      functions.  Remove references to the now-obsolete focus hooks.
      
      * lisp/frame.el (frame-focus-state): New function.
      (after-focus-change-function): New variable.
      (focus-in-hook, focus-out-hook): Move to lisp from C;
      mark obsolete.
      
      * lisp/term/xterm.el (xterm-translate-focus-in)
      (xterm-translate-focus-out): Track tty focus in `tty-focus-state'
      terminal parameter; call `after-focus-change-function'.
      (xterm--suspend-tty-function): New function.
      
      * src/frame.c (Fhandle_switch_frame): Update docstring; don't call
      focus hooks.
      (focus-in-hook, focus-out-hook): Remove: moved to lisp.
      (syms_of_frame): Remove unread_switch_frame; add
      Vunread_switch_frame.
      
      * src/keyboard.c:
      (Finternal_handle_focus_in): New function.
      (make_lispy_event): Always report focus events to lisp; don't
      translate them to switch events sometimes.  Lisp can take care of
      creating synthetic switch-frame events via
      `internal-handle-focus-in'.
      
      * src/w32term.c (x_focus_changed): Remove switch-avoidance logic:
      just directly report focus changes to lisp.
      
      * src/xterm.c (x_focus_changed): Remove switch-avoidance logic:
      just directly report focus changes to lisp.
