* ; Improve commentary in xdisp.cEli Zaretskii2019-08-171-24/+73
| | | | | * src/xdisp.c: Add to the commentary the description of stop_charpos, and how it is used during iteration.

* Ignore pending_signals when checking for quits.Philipp Stephani2019-08-072-7/+4
| | | | | | | | | | | pending_signals is often set if no quit is pending. This results in bugs in module code if the module returns but no quit is actually pending. * src/emacs-module.c (module_should_quit): Use QUITP macro to check whether the caller should quit. * src/eval.c: Remove obsolete comment.
* Fix subproc listening when setting filter to non-t (Bug#36591)Noam Postavsky2019-07-251-3/+12
| | | | | | | | | | | * src/process.c (Fset_process_filter): Call add_process_read_fd according to the state of process filter before it's updated. This restores the correct functioning as it was before 2016-02-16 "Allow setting the filter masks later". Inline the set_process_filter_masks call instead of fixing it that function, because it is also called from connect_network_socket, and we don't want to change the behavior of that function so close to release. * test/src/process-tests.el (set-process-filter-t): New test.

* Add warning to bidi-display-reordering doc stringStefan Kangas2019-07-131-2/+3
| | | | | | | | | | This explanation was given by Eli Zaretskii on emacs-devel. For discussion, see: https://lists.gnu.org/archive/html/emacs-devel/2019-07/msg00294.html * src/buffer.c (syms_of_buffer): Add warning to doc string of bidi-display-reordering to explain that it should only be used for debugging.

* Check that length of data returned by sysctl is non-zeroRobert Pluim2019-06-202-6/+6
| | | | | | | | | | | | The length of the data returned by sysctl can be zero, which was not checked for. This could cause crashes, e.g. when querying non-existent processes. (Bug#36279) * src/sysdep.c (list_system_processes) [DARWIN_OS || __FreeBSD__]: (system_process_attributes) [__FreeBSD__]: (system_process_attributes) [DARWIN_OS]: * src/filelock.c (get_boot_time) [CTL_KERN && KERN_BOOTTIME]: Check for zero length data returned by sysctl.
* Avoid assertion violation when comparing with main-threadEli Zaretskii2019-06-103-0/+9
| | | | | | | | | * src/thread.c (unmark_main_thread): New function. * src/lisp.h (unmark_main_thread): Prototype it. * src/alloc.c (garbage_collect_1): Call it after sweeping. (Bug#33073) * test/src/thread-tests.el (threads-test-bug33073): New test.

* Pacify GCC 9 -Wredundant-declsPaul Eggert2019-05-301-8/+1
| | | | | | | | * src/gmalloc.c (_fraghead) [!HYBRID_MALLOC]: Make it static in this case, too. This avoids having both ‘extern struct list _fraghead[];’ and ‘static struct list _fraghead[BLOCKLOG];’, which GCC 9 complains about.
* Pacify librsvg 2.45.1 and laterPaul Eggert2019-05-301-0/+15
| | | | | | * src/image.c (svg_load_image): Pacify librsvg 2.45.1 and later, and add a FIXME comment about the deprecated librsvg functions. Backport from master.
* Simplify xd_signature to pacify GCC 9Paul Eggert2019-05-301-5/+3
| | | | | | * src/dbusbind.c (xd_signature): Use simpler way to set up the subsignature. This also pacifies GCC 9 on Fedora 30 x86-64. Backport from master.

| | | | * src/unexelf.c (unexec): Pacify GCC 9.

| | | | | | | | | * doc/lispref/nonascii.texi (Explicit Encoding): Document what happens when DESTINATION of decoding is a unibyte buffer. * src/coding.c (Fdecode_coding_region) (Fdecode_coding_string): Document what happens if DESTINATION is a unibyte buffer.
* ; * src/coding.c: Improve commentary. (Bug#34765)Eli Zaretskii2019-05-231-7/+14

* Don't segfault on force-window-update of deleted windowNoam Postavsky2019-05-201-1/+1
| | | | | * src/window.c (Fforce_window_update): Do nothing for deleted windows (Bug#35784).

* Backport: fix broken build on m68kPaul Eggert2019-05-141-52/+25
| | | | | | | | | | | | | | The GCC + valgrind fix caused the m68k build to fail (Bug#35711). Simplify string allocation a bit to make similar problems less likely in the future. * src/alloc.c (sdata, SDATA_NBYTES, SDATA_DATA) [GC_CHECK_STRING_BYTES]: Use the same implementation as with !GC_CHECK_STRING_BYTES, as the special case is no longer needed. (SDATA_ALIGN): New constant. (SDATA_SIZE): Remove this macro, replacing with ... (sdata_size): ... this new function. All uses changed. Properly account for sizes and alignments even in the m68k case, and even if GC_CHECK_STRING_BYTES is not defined.
* Handle GNUTLS_E_AGAIN in emacs_gnutls_read (Bug#34341)Noam Postavsky2019-05-131-2/+9
| | | | | | | Don't merge to master, this has already been fixed there by 2019-01-15 "Fix unlikely races with GnuTLS, datagrams". * src/gnutls.c (emacs_gnutls_read): Similar to emacs_gnutls_write, when gnutls_record_recv returns GNUTLS_E_AGAIN set errno to EGAIN.
* Fix description of (move-to-column <n> t) when column <n> is inside a tabAlan Mackenzie2019-05-091-3/+4
| | | | | | | | This fixes bug #35647. State that when indent-tabs-mode is non-nil, spaces are inserted before the tab rather than the tab being replaced by spaces. * doc/lispref/text.texi (columns) * src/indent.c (move-to-column): Make the above documentation amendment.
* ; * src/lisp.h (DEFSYM): Fix inaccurate comment.Eli Zaretskii2019-05-061-1/+1

* Check if mouse_face_overlay was deleted (Bug#35273)Noam Postavsky2019-04-281-1/+3
| | | | | | * src/xdisp.c (note_mouse_highlight): Check if the mouse_face_overlay actually points to a buffer, before calling mouse_face_overlay_overlaps on it.
* Use pkg-config to find lcms2 CFLAGS and LIBS (Bug#30346)Noam Postavsky2019-04-211-3/+4
| | | | | | | | | * configure.ac: Use EMACS_CHECK_MODULES fors LCMS2 rather than AC_SEARCH_LIBS. * src/Makefile.in: Get LCMS2_LIBS and LCMS2_CFLAGS from configure, instead of just LIBLCMS2. (cherry picked from commit cb3863370cbe574810f796726faa39ba0de0a429)

| | | | | | | | | | * src/msdos.c (the_only_tty_output): Define. * src/msdos.h (the_only_tty_output): Declare. * src/frame.c (make_terminal_frame) [MSDOS]: * src/dispnew.c (init_display) [MSDOS]: Set up f->output_data.tty pointer using the_only_tty_output, before dereferencing the pointer. This prevents crashes with DPMI servers that provide NULL pointer protection.
* Backport: Plug memory leak in GTK x-display-monitor-attributes-listAlexander Gramiak2019-04-142-3/+8
| | | | | | | | | * src/frame.c (free_monitors) [USE_GTK]: Define in the GTK case as well. * src/xfns.c (x-display-monitor-attributes-list) [USE_GTK]: Plug memory leak. Use dupstring over xstrdup as gdk_monitor_get_model may return NULL.

| | | | | | | | | | | | * src/keyboard.c (read_char, read_event_from_main_queue): Ensure the global value of getcjmp is restored when the stack is unwound by the likes of 'throw', by calling record_unwind_protect_ptr instead of restoring the value manually. (Bug#34394) (restore_getcjmp): Argument is now 'void *', to match the signature of record_unwind_protect_ptr. (cherry picked from commit 10527fca66e39d7067986904161fa33741abcd26)
