* Change vectorlike from struct to unionPaul Eggert2017-11-1312-33/+33
| | | | | | | * src/lisp.h (vectorlike_headed): Change from struct to union. All uses changed. Since it has only one member, this does not change semantics. This is designed to simplify future changes needed to fix bugs like Bug#29040. All uses changed.
* Fix Bug#29225Michael Albinus2017-11-121-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | * src/fileio.c (Fset_file_acl): Report error only when acl_errno_valid returns true. (Bug#29225) * test/lisp/net/tramp-tests.el (tramp-test24-file-acl) (tramp-test25-file-selinux): New tests. (tramp-test26-file-name-completion, tramp-test27-load) (tramp-test28-process-file, tramp-test29-start-file-process) (tramp-test30-interrupt-process, tramp-test31-shell-command) (tramp-test32-environment-variables) (tramp-test32-environment-variables-and-port-numbers) (tramp-test33-explicit-shell-file-name) (tramp-test34-vc-registered) (tramp-test35-make-auto-save-file-name) (tramp-test36-find-backup-file-name) (tramp-test37-make-nearby-temp-file) (tramp-test38-special-characters) (tramp-test38-special-characters-with-stat) (tramp-test38-special-characters-with-perl) (tramp-test38-special-characters-with-ls, tramp-test39-utf8) (tramp-test39-utf8-with-stat, tramp-test39-utf8-with-perl) (tramp-test39-utf8-with-ls, tramp-test40-file-system-info) (tramp-test41-asynchronous-requests) (tramp-test42-recursive-load, tramp-test43-remote-load-path) (tramp-test44-delay-load, tramp-test45-unload): Rename.
* Pacify GCC when configured --with-x-toolkit=noPaul Eggert2017-11-111-1/+4
| | | | | | | | Without these changes, Emacs does not build on Fedora 26 x86-64 when configured --with-x-toolkit=no --enable-gcc-warnings. * oldXMenu/Activate.c (XMenuActivate): Add FALLTHROUGH. * src/xterm.c (x_dispatch_event): Define only if USE_X_TOOLKIT || USE_MOTIF || USE_GTK.
* Fix comparisons with tip_frame in GTK buildsEli Zaretskii2017-11-113-4/+20
| | | | | | | * src/xterm.c (x_update_begin, x_new_font): * src/xfns.c (Fx_display_monitor_attributes_list): * src/frame.c (Fframe_list) [USE_GTK]: Don't consider tip_frame a tooltip frame unless its 'tooltip' parameter is non-nil. (Bug#26747)
* Fix off-by-1 bug in --enable-checking=stringbytesPaul Eggert2017-11-101-1/+1
| | | | | | | | | | | | Evidently nobody builds Emacs with --enable-checking=all, which is no surprise as it is so slow as to be unusable nowadays. Perhaps we should remove the slowest checks, or move them into another category, or speed them up, or something. * src/alloc.c (SDATA_SIZE) [GC_CHECK_STRING_BYTES]: Fix off-by-one error in size calculation, which caused a failure when --enable-checking=stringbytes was used. I introduced this bug in 2016-09-08T01:08:45!eggert@cs.ucla.edu "Port flexible array members to GCC + valgrind".
* Fix display of line numbers in GTK buildsEli Zaretskii2017-11-102-1/+14
| | | | | | | | | * src/xdisp.c (should_produce_line_number) [USE_GTK]: Make sure tip_frame is indeed a tooltip frame, before disabling line numbers on it. (Bug#27647) * src/dispextern.h (tip_frame): Add commentary describing the kludgey usage of this variable in GTK builds.
* Fix redisplay of overlay-arrows on GUI framesEli Zaretskii2017-11-091-3/+9
| | | | | | * src/xdisp.c (try_window_reusing_current_matrix) (try_cursor_movement): Disallow these optimizations if the buffer has overlay arrow(s) shown on the fringe(s). (Bug#29198)
* Use GCALIGNED properly for GCCPaul Eggert2017-11-083-9/+13
| | | | | | | | | | | | | Apparently GCC requires that ‘__attribute__ ((aligned (8)))’ must immediately follow the ‘struct’ keyword when aligning a structure. The attribute silently does not work if it follows a tag after the ‘struct’ keyword. Who knew? Anyway, this patch is designed to fix a SIGSEGV problem reported by John Mastro (Bug#29183). * lib-src/make-docfile.c (close_emacs_globals): * src/buffer.c (buffer_defaults, buffer_local_symbols): * src/lisp.h (DEFUN): * src/thread.c (main_thread): Put 'GCALIGNED' immediately after 'struct'.
* ; Minor comment copyedit in window.cEli Zaretskii2017-11-071-1/+1
| | | | | * src/window.c (Fset_window_configuration): Don't use non-ASCII quotes in comments.
* Fix last change in hscroll_window_treeEli Zaretskii2017-11-051-3/+8
| | | | | | * src/xdisp.c (hscroll_window_tree): When hscroll suspension is being disabled, set the frame's garbaged flag less eagerly. (Bug#29002)
* Return non-nil from gnutls-available-p under GnuTLS 2.xEli Zaretskii2017-11-051-0/+2
| | | | | | | | | | | * doc/misc/emacs-gnutls.texi (Help For Users): Update the documentation of 'gnutls-available-p'. * etc/NEWS (GnuTLS): Mention the change in the value returned by 'gnutls-available-p'. * src/gnutls.c (Fgnutls_available_p): Return non-nil when GnuTLS 2.x is available. (Bug#29147)
* Use hybrid malloc for FreeBSD (Bug#28308)Noam Postavsky2017-11-041-5/+6
| | | | | | | | FreeBSD aarch64 does not provide sbrk, so gmalloc cannot be used; when using system malloc dumping does not work correctly (allocated data is invalid after dumping). * configure.ac: Set hybrid_malloc for freebsd. * src/gmalloc.c (gdefault_morecore) [!HAVE_SBRK]: Don't call sbrk.
* Improve documentation of 'window-scroll-functions'Eli Zaretskii2017-11-041-0/+3
| | | | | | | * doc/lispref/windows.texi (Window Hooks): Clarify the values of arguments of 'window-scroll-functions' functions. * src/xdisp.c (syms_of_xdisp) <window-scroll-functions>: Doc fix.
* Fix doc string of 'window-configuration-change-hook'Eli Zaretskii2017-11-041-2/+2
| | | | | * src/window.c (syms_of_window) <window-configuration-change-hook>: Doc fix. (Bug#29049)
* Fix hscroll suspension after cursor motionEli Zaretskii2017-11-041-2/+9
| | | | | | * src/xdisp.c (hscroll_window_tree): Trigger a thorough redisplay of the window when temporary suspension of hscrolling is disabled. (Bug#29002)
* Change GCALIGNMENT back to an integer literalPaul Eggert2017-11-031-1/+7
| | | | | | | * src/lisp.h (GCALIGNMENT): Change it back to a macro that expands to a literal integer constant, for older GCC. I had mistakenly thought that only MSVC had the problem. Problem repored by Eli Zaretskii (Bug#29040#69).
* * src/lisp.h (GCALIGNED): Clarify comment (Bug#29040).Paul Eggert2017-11-021-2/+3

* Fix alignment portability problemsPaul Eggert2017-11-024-22/+17
| | | | | | | | | | | | | | | | Do not assume that the natural alignment of Lisp objects is a multiple of GCALIGNMENT. This improves on the portability of the recent fix for Bug#29040. * lib-src/make-docfile.c (close_emacs_globals): * src/buffer.c (buffer_defaults, buffer_local_symbols): * src/lisp.h (DEFUN): * src/thread.c (main_thread): Use GCALIGNED, not alignas (GCALIGNMENT). * src/alloc.c (COMMON_MULTIPLE): Move back here from lisp.h, since it is no longer used elsewhere. * src/lisp.h (GCALIGNMENT): No longer a macro, since we need not worry about MSVC. Omit no-longer-needed consistency check. * src/thread.c (THREAD_ALIGNMENT): Remove.

* Port to QNXPaul Eggert2017-10-241-6/+9
| | | | | | | | | | | | Simplified version of a patch proposed by Elad Lahav in: https://lists.gnu.org/archive/html/emacs-devel/2017-10/msg00716.html which is based on a previous patch I proposed in: https://lists.gnu.org/archive/html/emacs-devel/2017-10/msg00707.html * configure.ac (opsys, CFLAGS, LIBS_SYSTEM, hybrid_malloc) (system_alloc, FIRST_PTY_LETTER, CYGWIN_OBJ): Set appropriately for QNX. * src/unexelf.c [__QNX__]: Include <sys/elf.h> instead of <elf.h>. (unexec): Check for sbrk failure, and fall back on old BSS end.
* Tweak Fdocumentation's error for an undefined functionGlenn Morris2017-10-201-0/+2
| | | | | | | | * src/doc.c (Fdocumentation): Restore the pre-25 behavior of signalling a void-function error for an undefined function. This seems cleaner than Emacs 25's "invalid-function: nil" error, which was (probably) an unintended consequence of changes to Findirect_function.
* Make :align-to account for display-line-numbersEli Zaretskii2017-10-202-10/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These changes also update the various bundled packages to use new feature, and better support customizations of the line-number face. * src/xdisp.c (calc_pixel_width_or_height): Improve commentary. Make :align-to count from the end of the line-number display when the offset or the width form reference that of the text area. (Bug#28855) * src/indent.c (Fline_number_display_width): Implement support for the PIXELWISE argument being 'columns'. Update the doc string. (syms_of_indent): New symbol 'columns'. * lisp/ruler-mode.el (ruler-mode-window-col, ruler-mode-ruler): Call line-number-display-width with last argument 'columns'. * lisp/proced.el (proced-header-line): Call line-number-display-width with 2nd arg 'columns', which also fixes a problem when display-line-numbers is nil. * lisp/emacs-lisp/tabulated-list.el (tabulated-list-line-number-width): Call line-number-display-width with 2nd arg 'columns. (tabulated-list-entry-lnum-width): Remove unneeded defvar. (tabulated-list-print, tabulated-list-print-entry): No need to account for the value of tabulated-list-entry-lnum-width. (tabulated-list--current-lnum-width): New defvar. (tabulated-list-watch-line-number-width): New function. (tabulated-list-mode): Bind tabulated-list--current-lnum-width locally, and set up tabulated-list-watch-line-number-width as pre-redisplay-functions hook. * doc/lispref/display.texi (Size of Displayed Text): Document the 'columns' value of the PIXELWISE argument. (Pixel Specification): Update and improve the documentation of the supported forms.
