| * 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.
| * 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.
| * Speed up 'resize-mode' child frames a littleDmitry Gutov2020-04-081-8/+16
| | | | | | | | | | | | * src/gtkutil.c (xg_frame_set_char_size): Skip resizing if the target dimensions are unchanged for child frames with 'resize-mode' resize policy as well.
| * 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.

* | Fix ASCII-only conversion logic (bug#40407)Mattias Engdegård2020-04-091-29/+17
| | | | | | | | | | | | | | | | | | | | | | 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.
* | Don't crash with invalid argument in check-coding-systems-regionMattias Engdegård2020-04-091-1/+4
| | | | | | | | | | | | | | * src/coding.c (Fcheck_coding_systems_region): Don't crash if the third arg contains something that isn't a coding system. * test/src/coding-tests.el (coding-check-coding-systems-region): New test.
* | Don't rely on copying in {EN,DE}CODE_FILEMattias Engdegård2020-04-092-3/+3
| | | | | | | | | | | | | | | | | | | | Callers of ENCODE_FILE and DECODE_FILE should not assume that these functions always return a new string (bug#40407). * src/w32fns.c (Fw32_shell_execute): * src/w32proc.c (Fw32_application_type): Sink taking the address of a Lisp string past GC points. Copy values returned from ENCODE_FILE before mutating them.
* | Fix decoding of ASCII strings with embedded CR charactersEli Zaretskii2020-04-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | * src/coding.c (string_ascii_p): Return a negative value if an all-ASCII string STR includes the CR character, otherwise a positive value. (code_convert_string): If the string is ASCII, but includes CR characters, use the fast path only if EOL doesn't need to be decoded. (Bug#40519) * test/src/coding-tests.el (coding-nocopy-ascii): Add more tests for bug#40519.

* | 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
* | Pacify gcc in xpm_scanPaul Eggert2020-04-061-2/+3
| | | | | | | | | | * src/image.c (xpm_scan): Redo a loop for clarity. This also pacifies --enable-gcc-warnings (GCC 9.3.1 x86-64 with -Og).

| | | | | | | | | | | | | | | | | | | | Optimise for the common case of encoding or decoding an ASCII-only string using an ASCII-compatible coding, for file names in particular. * src/coding.c (string_ascii_p): New function.

| | | | | | | | | | | | | | | | | | | | In {encode,decode}-coding-string, the NOCOPY parameter had the opposite effect to what was intended and documented. This 18 year old bug (introduced in 4031e2bf0a) only affected calls with CODING-SYSTEM being nil. * src/coding.c (code_convert_string): Correct use of NOCOPY. * test/src/coding-tests.el (coding-nocopy-trivial): New test.

(Fset_frame_height, Fset_frame_width, Fset_frame_size): Use it. * src/lisp.h (CHECK_RANGED_INTEGER, CHECK_TYPE_RANGED_INTEGER): Remove these macros. Unless otherwise specified, all callers replaced by calls to check_integer_range, check_uinteger_range, check_int_nonnegative. * src/frame.c (gui_set_right_divider_width) (gui_set_bottom_divider_width): * src/nsfns.m (ns_set_internal_border_width): * src/xfns.c (x_set_internal_border_width): Using check_int_nonnegative means these functions no longer incorrectly reject negative bignums; they treat them as 0, just like negative fixnums.

* | Make make-{network,serial}-process handle :coding nil consistentlyRobert Pluim2020-04-031-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The handling of :coding nil was different between make-{network,serial}-process and make-{pipe}process. Now they all handle :coding nil as if :coding had not been specified. * process.c (Fmake_serial_process) (set_network_socket_coding_system): Use plist-get to check if :coding has been specified instead of plist-member, to ensure that ":coding nil" does not override coding-system-for-{read,write}. * network-stream-tests.el (check-network-process-coding-system-bind) (check-network-process-coding-system-no-override) (check-network-process-coding-system-override): New tests. * etc/NEWS: Describe change in make-network-process and make-serial-process :coding behavior.

* | Add a module function to open a file descriptor connected to a pipe.Philipp Stephani2020-03-264-0/+26

While it isn't possible to call arbitrary Emacs functions asynchronously, writing to a pipe should always be fine and is a pretty low-hanging fruit. This patch implements a function that adapts an existing pipe process. That way, users can use familiar tools like process filters or 'accept-process-output'. * src/module-env-28.h: Add 'open_channel' module function. * src/emacs-module.c (module_open_channel): Provide definition for 'open_channel'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | backtrace_eval_unrewind is used to temporarily reverse let-bindings (it's called with a positive argument to reverse bindings, and then a negative argument to re-apply them) by backtrace--locals and backtrace-eval. For the SPECPDL_LET_DEFAULT and SPECPDL_LET_LOCAL cases (which occur for let-bindings on buffer-local variables), the code calls Fdefault_value and Fbuffer_local_value on the symbol. For symbols which are unbound at top-level, the first (with positive argument) call to backtrace_eval_unrewind will set the symbol's value to unbound (putting the current value in the specpdl's "old value" slot). On the second (with negative argument) call, backtrace_eval_unrewind attempts to retrieve the symbol's value with Fdefault_value or Fbuffer_local_value, but that raises a void-variable signal. This interrupts the restoration of the let-bindings, so any other variables more recent on the stack will now have the wrong value. * src/data.c (default_value): Make non-static. * src/lisp.h: Declare it. * src/eval.c (backtrace_eval_unrewind): Replace the calls to Fdefault_value and Fbuffer_local_value with default_value and buffer_local_value, respectively. The latter do exactly the same as the former, except if the symbol's value is Qunbound they just return it instead of signaling void-variable.
