| * Fix redisplay when scrolling under redisplay-dont-pauseEli Zaretskii2020-04-101-0/+4
| | | | | | | | | | | | | | | | | | * src/dispnew.c (update_window): Reset the window's 'must_be_updated_p' flag if the window's update was completed without interruption. This fixes redisplay glitches when 'redisplay-dont-pause' is nil, at least on MS-Windows, because 'expose_window' doesn't redraw the exposed rectangle when the window's 'must_be_updated_p' flag is set.
| * Fix face extension in pulse.elEli Zaretskii2020-04-091-0/+3

| * Avoid assertion violation in intervals.cEli Zaretskii2020-04-091-1/+1
| | | | | | | | | | | | | | | | | | | | * src/intervals.c (delete_interval): Allow negative values of LENGTH (i). This happens when delete_interval is called from set_intervals_multibyte_1, because the caller zeroes out the total_length field of the interval to be deleted. See https://lists.gnu.org/archive/html/emacs-devel/2020-04/msg00131.html for more details. See also a related old discussion at https://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00399.html.

| * Fix some problems with moving and resizing child framesMartin Rudalics2020-04-064-25/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (1) Provide new option 'x-gtk-resize-child-frames' which allows to either hide a child frame during resizing or asks GTK to resize it "immediately". This is needed because desktops like GNOME shell otherwise won't allow resizing child frames at all. (2) Do not try to synchronize the position of a child frame after moving it. Needed because the present implementation introduces a 0.5 secs delay which makes dragging child frames virtually impossible with Lucid and Motif toolkits on desktops like GNOME shell that use invisible outer frame borders. For further information see the thread starting with https://lists.gnu.org/archive/html/emacs-devel/2020-01/msg00343.html * src/frame.c (syms_of_frame): New symbol Qxg_frame_set_char_size_4. * src/gtkutil.c (xg_frame_set_char_size): Hide child frame during resizing when 'x-gtk-resize-child-frames' equals 'hide'. * src/xfns.c (x_set_parent_frame, Fx_create_frame): Set gtk_container_resize_mode to GTK_RESIZE_IMMEDIATE for child frames when'x-gtk-resize-child-frames' equals 'resize-mode'. (Fx_gtk_debug): New function to toggle interactive GTK debugging from within Emacs. (syms_of_xfns): New symbols Qhide and Qresize_mode. (x-gtk-resize-child-frames): New option that allows to resize child frames on desktops like GNOME shell (with the mutter WM) that otherwise refuse to resize them. * src/xterm.c (x_set_offset): Don't x_sync_with_move for child frames, it makes moving child frames virtually impossible with the Lucid and Motif toolkits.

| | | | | | | | | | | | | | | | | | | | | | To sidestep conversion altogether when EOL conversion applies, we must either be encoding a string without NL, or decoding without CR. * src/coding.c (string_ascii_p): Revert to a pure predicate. (code_convert_string): Fix logic. Don't use uninitialised ascii_p (removed). Use memchr to detect CR or LF in string when needed. * test/src/coding-tests.el (coding-nocopy-ascii): Update tests to include encodings with explicit EOL conversions.

* | Revert my KEY_OPS_CFLAGS change to src/Makefile.inPaul Eggert2020-04-071-5/+2
| | | | | | | | | | | | | | | | Now that -Og inlining has been improved this is no longer helpful. * src/Makefile.in (KEY_OPS_CFLAGS): Remove. All uses removed. This improved CPU performance of ‘make compile-always’ by 5% on my platform, which was gcc -Og, GCC 9.3.1 20200317 (Red Hat 9.3.1-1), Fedora 31 x86-64 (AMD Phenom II X4 910e, circa 2010).
* | Improve inlining when compiling with -OgPaul Eggert2020-04-071-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/conf_post.h (EXTERN_INLINE) [!EMACS_EXTERN_INLINE]: Make it static inline, not merely static. This is a worthwhile performance improvement on my two platforms A and B (see below). On my platform A this change improves user+system CPU performance of ‘make compile-always’ by 52% on an -Og build, and by 1.4% on the default -O2 build. On my platform B this improves the same benchmark by 41% on an -Og build, and by -0.8% on the default -O2 build. That "-0.8%" is a small negative for this change, and I recall that it is why I didn't make this change earlier. However, Platform B uses an older GCC so we needn't worry overmuch about this small negative. With this change the performance advantage of -O2 over -Og has dropped on platform A; formerly -O2 was 87% faster than -Og, and now it is only 25% faster. On platform B the performance advantage of -O2 over -Og has dropped from being 62% faster to being 14% faster. Platform A is GCC 9.3.1 20200317 (Red Hat 9.3.1-1) on Fedora 31 x86-64 (AMD Phenom II X4 910e, circa 2010). Platform B is GCC (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0 on Ubuntu 18.04.4 (Intel Xeon E3-1225 V2, circa 2012). This patch was inspired by a suggestion by Andrea Corallo in: https://lists.gnu.org/r/emacs-devel/2020-04/msg00263.html

* | Unify and improve gdb-mi source buffer display logicYuan Fu2020-04-064-26/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unify the behavior of source buffer display for gdb-mi. Before this change, stepping and other gdb command handlers use 'gud-display-line', and 'gdb-goto-breakpoint' uses 'gdb-display-source-buffer'. Now whenever gdb-mi code tries to open a source buffer, 'gdb-display-source-buffer' is used. Also, simplify the logic in 'gdb-display-source-buffer' and add a feature to limit the maximum number of source windows. * doc/emacs/building.texi (GDB User Interface Layout): Explain source file display in GDB. * etc/NEWS (gdb-mi): Add news about source display. * lisp/progmodes/gdb-mi.el (gdb-source-window): Remove variable, change to 'gdb-source-window-list'. (gdb-source-window-list): New variable. (gdb-display-source-buffer-action, gdb-max-source-window-count): New options. (gdb-init-1, gdb-setup-windows, gdb-load-window-configuration, gdb-restore-windows): Use 'gdb-source-window' rather than 'gdb-source-window-list'. (gdb-save-window-configuration): Use 'gdb-source-window' rather than 'gdb-source-window-list'. And consider any buffer that is not a command or function buffer as a source buffer. (gdb-display-source-buffer): Use new logic. (gdb-goto-breakpoint): Remove 'display-buffer' call and don't set 'gdb-source-buffer' anymore. * lisp/progmodes/gud.el (gud-display-line): If used by gdb-mi, use 'gdb-display-source-buffer' rather than 'display-buffer'. Don't set 'gdb-source-buffer' anymore.
* | Fix problems when dragging frames with the mouseMartin Rudalics2020-04-061-234/+292
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Re-implement 'mouse-drag-frame' via two new functions - 'mouse-drag-frame-resize' and 'mouse-drag-frame-move'. This is needed because with some toolkits the notifications for frame movement and resizing arrive asynchronously, breaking any calculations using intermediate frame sizes and positions. * lisp/mouse.el (mouse-drag-mode-line, mouse-drag-left-edge) (mouse-drag-top-left-corner, mouse-drag-top-edge) (mouse-drag-top-right-corner, mouse-drag-right-edge) (mouse-drag-bottom-right-corner, mouse-drag-bottom-edge) (mouse-drag-bottom-left-corner): Call 'mouse-drag-frame-resize' instead of 'mouse-drag-frame'. (mouse-drag-frame): Split into two new functions - 'mouse-drag-frame-move' and 'mouse-drag-frame-resize'. (mouse-drag-frame-resize, mouse-drag-frame-move): New functions to implement functionality of the removed 'mouse-drag-frame'.
