| * Finish up native display of line numbersEli Zaretskii2017-06-172-29/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/xdisp.c (maybe_produce_line_number): Produce a blank before the number, for R2L rows. Increment 'g' in the loop even if glyph_row is NULL. Accept 2nd argument FORCE and produce the line-number glyphs if it is non-zero. (move_it_in_display_line_to): Account for the space taken by the line-number glyphs. Call maybe_produce_line_number with 2nd argument non-zero. (set_cursor_from_row): Fix calculation of cursor X coordinate in R2L rows with display-produced glyphs at the beginning. (syms_of_xdisp) <line-number>: New face symbol. <relative, display-line-width>: New symbols. (maybe_produce_line_number): Use the line-number face for displaying line numbers. Support relative line-number display. Support user-defined width for displaying line numbers. (try_cursor_movement, try_window_id): Disable these optimizations when displaying relative line numbers. * src/dispextern.h (struct it): New member 'pt_lnum'. * lisp/faces.el (line-number): New face. * lisp/cus-start.el (standard): Provide customization forms for display-line-numbers and display-line-width. * lisp/menu-bar.el (menu-bar-showhide-menu): Add menu-bar item to turn display-line-numbers on and off. * etc/NEWS: Document the new feature.
| * Initial version of native display of line numbersEli Zaretskii2017-06-162-7/+187
| | | | | | | | | | | | | | | | | | | | | | * src/xdisp.c (syms_of_xdisp) <display-line-numbers>: New buffer-local variable. Include <math.h>. (maybe_produce_line_number): New function. (DISP_INFINITY): Rename from INFINITY, since math.h defines INFINITY. (try_window_reusing_current_matrix): Don't use this method when display-line-numbers is in effect. * src/dispextern.h (struct it): New members 'lnum'.
* | Fix more ungetc bugs with encoding errorsPaul Eggert2017-07-071-29/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/lread.c (infile): New variable, replacing ... (instream): ... this. All uses changed. (readbyte_from_stdio): New function, which deals with lookahead. (readbyte_from_file, Fget_file_char): Use it. (Fget_file_char): When misused, signal an error instead of relying on undefined behavior. (close_infile_unwind): New function. (Fload): Use it. (readevalloop): 2nd arg is now struct infile *, not FILE *. All callers changed. (read1): Handle lookahead when copying doc strings with encoding errors.
* | Avoid ungetc when loading charset maps from filesPaul Eggert2017-07-071-41/+49
| | | | | | | | | | | | * src/charset.c (read_hex): New args LOOKAHEAD and TERMINATOR, replacing the old EOF. All callers changed. This avoids the need to call ungetc.
* | Fix ungetc bug when reading an encoding errorPaul Eggert2017-07-071-6/+4
| | | | | | | | | | | | * src/lread.c (readchar, read_emacs_mule_char): Fix off-by-one error when reading an encoding error from a file, e.g., a symbol in an .elc file whose name is "\360\220\200\360".
* | Remove Vwindow_text_change_functions and related codeMartin Rudalics2017-07-071-19/+0
| | | | | | | | | | | | | | | | | | | | | | | | Vwindow_text_change_functions had been provided for implementing line numbers but apparently was never functional or in use. * src/xdisp.c (redisplay_window): Remove handling of Vwindow_text_change_functions. (syms_of_xdisp): Remove Qwindow_text_change_functions. (Vwindow_text_change_functions): Remove variable. * doc/lispref/hooks.texi (Standard Hooks): Remove entry for `window-text-change-functions'.

* | Convert hex digits more systematicallyPaul Eggert2017-07-057-39/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the code a bit smaller and presumably faster, as it substitutes a single lookup for conditional jumps. * src/character.c (hexdigit): New constant. (syms_of_character) [HEXDIGIT_IS_CONST]: Initialize it. * src/character.h (HEXDIGIT_CONST, HEXDIGIT_IS_CONST): New macros. (hexdigit): New decl.

* | Don’t use -Woverride-initPaul Eggert2017-07-051-12/+0
| | | | | | | | | | | | | | | | | | I have some further changes in mind that would also need to disable the -Woverride-init warnings. In practice these warnings seem to be more trouble than they’re worth, so disable them in the cc command line. * configure.ac: Disable -Woverride-init here ... * src/bytecode.c: ... rather than here.
* | Remove FIXME comments about sentinel valuesPhilipp Stephani2017-07-021-4/+0
| | | | | | | | | | | | | | | | | | | | | | These FIXMEs can't be addressed because they would require breaking changes to the module API. Furthermore, other module functions don't return sentinel values as well, so users generally have to call non_local_exit_check anyway. * src/emacs-module.c (module_set_user_ptr) (module_set_user_finalizer, module_vec_set, module_vec_size): Remove FIXME comments.
* | * src/module-env-25.h (copy_string_contents): Fix comment.Philipp Stephani2017-07-011-1/+1
| |
* | Also mark module init function as noexcept if possiblePhilipp Stephani2017-07-011-0/+1
| | | | | | | | | | * src/emacs-module.h.in (emacs_module_init): Mark as noexcept if possible.
* | Improve C++98 compatibilityPhilipp Stephani2017-07-011-1/+1
| | | | | | | | | | * src/emacs-module.h.in (emacs_funcall_exit): Lose trailing comma. C++98 doesn't allow trailing commas in enumerations.
* | Fix threads on NS (bug#25265)Alan Third2017-07-014-13/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | src/nsterm.h (ns_select): Compiler doesn't like sigmask being const. (ns_run_loop_break) [HAVE_PTHREAD]: New function. src/nsterm.m (ns_select): Call thread_select from within ns_select. (ns_run_loop_break) [HAVE_PTHREAD]: New function. (ns_send_appdefined): Don't wait for main thread when sending app defined event. src/process.c (wait_reading_process_output): Call thread_select from within ns_select. src/systhread.c (sys_cond_broadcast) [HAVE_NS]: Break ns_select out of its event loop using ns_run_loop_break.
* | Escape control characters in backtraces (Bug#6991)Noam Postavsky2017-06-291-12/+33
| | | | | | | | | | | | | | | | | | | | * src/print.c (syms_of_print): Add new variable, print-escape-control-characters. (print_object): Print control characters with octal escape codes when print-escape-control-characters is true. * lisp/subr.el (backtrace): * lisp/emacs-lisp/debug.el (debugger-setup-buffer): Bind `print-escape-control-characters' to t.
* | Avoid segfaults when some display vector is an empty stringEli Zaretskii2017-06-271-3/+2
| | | | | | | | | | * src/xdisp.c (next_element_from_display_vector): Don't try accessing the dpvec[] array if its size is zero. (Bug#27504)
* | ; * src/emacs-module.c (module_make_string): Add another FIXMEPhilipp Stephani2017-06-261-0/+2
| |
* | Omit null-pointer test in intervals.h FRAMEPaul Eggert2017-06-251-6/+6
| | | | | | | | | | | | | | | | | | * src/intervals.h (ROOT_INTERVAL_P, ONLY_INTERVAL_P) (INTERVAL_LAST_POS): Omit unnecessary parens. (LENGTH): Omit test for null pointer. The argument is never null. The unnecessary test causes GCC 7.1.0 to assume that the argument might be null, and therefore to issue false alarms when the argument is dereferenced in other expressions.
* | Parenthesize frame.h macro definitionsPaul Eggert2017-06-251-18/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | * src/frame.h (FRAME_TOOL_BAR_POSITION) (FRAME_VERTICAL_SCROLL_BAR_TYPE, FRAME_HAS_VERTICAL_SCROLL_BARS) (FRAME_HAS_VERTICAL_SCROLL_BARS_ON_LEFT) (FRAME_HAS_VERTICAL_SCROLL_BARS_ON_RIGHT) (FRAME_OVERRIDE_REDIRECT, FRAME_UNDECORATED, FRAME_PARENT_FRAME) (FRAME_SKIP_TASKBAR, FRAME_NO_FOCUS_ON_MAP) (FRAME_NO_ACCEPT_FOCUS, FRAME_NO_SPECIAL_GLYPHS, FRAME_Z_GROUP) (FRAME_Z_GROUP_NONE, FRAME_Z_GROUP_ABOVE, FRAME_Z_GROUP_BELOW) (FRAME_HAS_HORIZONTAL_SCROLL_BARS): Parenthesize macro definiens to allow arbitrary expression arguments.
* | Port recent frame changes to GCC 7Paul Eggert2017-06-251-29/+23
| | | | | | | | | | | | * src/frame.c (keep_ratio): New arg P. Caller changed. Since it is non-null, it avoids a GCC 7 warning that FRAME_PARENT_FRAME might return null. This also avoids a run-time test.
* | Provide additional support for child framesMartin Rudalics2017-06-2518-386/+1412
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide mouse dragging and resizing of frames.

| * | Create less garbage to collect while reading symbols.Ken Raeburn2017-06-211-18/+44
| | | | | | | | | | | | | | | | | | * src/lread.c (read1): When interning a symbol, only create a new string object for the name if we're going to use it for a new symbol object.
| * | Replace read_objects assoc list with two hash tables.Ken Raeburn2017-06-211-18/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For larger input files with lots of shared data structures, an association list is too slow. * src/lread.c (read_objects_map, read_objects_completed): New variables, replacing read_objects. (readevalloop): Initialize them with hash tables before starting a top-level read, if they're not already empty hash tables, and reset them to Qnil afterwards if something was added to the hash tables. (read_internal_start): Likewise. (read1): Store first the placeholder and later the newly read object into read_objects_map under the specified object number. If the new object can contain a reference to itself, store it in read_objects_completed. (substitute_objects_recurse): Check read_objects_completed instead of read_objects for the known possibly-recursive objects. (syms_of_lread): Update initializations.

| * | Reduce lread substitutions.Stefan Monnier2017-06-211-4/+13
| | | | | | | | | | | | | | | | | | | | | * src/lread.c (read1): After reading an object using the "#n=" syntax, if the read object is a cons cell, instead of recursively substituting the placeholder with the new object, mutate the placeholder cons cell itself to have the correct car and cdr values.
| * | Short-circuit substitutions for some simple types.Ken Raeburn2017-06-211-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Values that don't contain other values cannot be circular, so checking for circular objects is a waste of cycles. * src/lread.c (substitute_object_recurse): If the subtree being examined is a symbol, number, or property-less string, just return it.
* | | Limit style_format to MAX_ALLOCAPaul Eggert2017-06-211-0/+1

| | | | | | | | | | | | | | | | | | | | | | | | * src/bidi.c (MAX_BPA_STACK): Now a constant, not a macro. Shrink it to allow for the two struct bidi_it objects in the same frame. (PUSH_BPA_STACK): Avoid integer overflow with enormous bidi cache. (bidi_find_bracket_pairs): Use compile-time check instead of runtime.

* | | Fix temacs hybrid_malloc core dumpPaul Eggert2017-06-211-30/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this patch, ./temacs would dump core sometimes on Fedora 25 x86-64. The problem was that the hybrid allocator assumed that all pointers into bss_sbrk_buffer are allocated via gmalloc. This assumption is not true on Fedora, because the standard memory allocator calls gdefault_morecore, which means its blocks are interleaved with our blocks. Usually the code happened to work, because our data structures agreed with the glibc data structures, but this was merely luck due to a shared pedigree, and as glibc mutates our luck has run out. * src/gmalloc.c (ALLOCATED_BEFORE_DUMPING) [HYBRID_MALLOC]: Remove; no longer needed. (BLOCK): Use unsigned division, as that does the right thing near zero. (register_heapinfo, __malloc_internal_nolock, __free_internal_nolock) (_realloc_internal_nolock): Big blocks now have type -1, not 0, as 0 now means the block is not ours. (morecore_nolock): Omit now-unnecessary casts to size_t. (allocated_via_gmalloc) [HYBRID_MALLOC]: New function. (hybrid_free, hybrid_realloc) [HYBRID_MALLOC]: Use it, to avoid calling the wrong free or realloc function in some cases.

| | | | | | | | | | | | | | | | | | | | | Problem reported by Andrés Musetti (Bug#27248). * src/widget.c (emacsFrameClassRec): Do not initialize superclass here. (emacsFrameClass): Now a function (which initializes the superclass) instead of a variable. All uses changed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was part of the original design of the module API (https://lists.gnu.org/archive/html/emacs-devel/2015-02/msg00960.html), but I didn't take it into account when adding the should_quit function. Instead of duplicating the environment fields or using the C preprocessor, use configure to build emacs-module.h. * configure.ac: Expand emacs-module.h template.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new command 'replace-buffer-contents' that uses the Myers diff algorithm to non-destructively replace the accessible portion of the current buffer. The Myers algorithm is implemented in Gnulib. * src/editfns.c (Freplace_buffer_contents): New command. (set_bit, bit_is_set, buffer_chars_equal): New helper functions. (syms_of_editfns): Define new command. * test/src/editfns-tests.el (replace-buffer-contents-1) (replace-buffer-contents-2): New unit tests. * src/buffer.h (BUF_FETCH_CHAR_AS_MULTIBYTE): New helper macro. * admin/merge-gnulib (GNULIB_MODULES): Add diffseq.h and minmax.h.
* | Pacify clang without munging C sourcePaul Eggert2017-06-151-2/+2
| | | | | | | | | | | | | | | | | | | | * configure.ac (WARN_CFLAGS): With Clang, use -Wno-tautological-compare regardless of --enable-gcc-warnings. (WERROR_CFLAGS): Simplify assignments, and guarantee it’s always set. * lib/strftime.c: Copy from gnulib, reverting Clang-specific change which I hope is no longer needed. * src/emacs.c (main): Revert rlim_t change, as rlim_t is signed on some older non-POSIX hosts.
* | Don’t worry about __STDC_VERSION__ in emacs-modulePaul Eggert2017-06-151-5/+0
| | | | | | | | | | | | | | * src/emacs-module.h: Remove __STDC_VERSION__ check. In the past we’ve found that some compilers do not define this symbol even when they work well enough. If necessary features like stdbool.h are missing the compiler will complain eventually anyway.
* | Port cleanup check to Oracle Studio 12.5Paul Eggert2017-06-142-1/+8

| | | | | | | | | | | | * src/image.c (x_create_x_image_and_pixmap) [HAVE_NTGUI]: Avoid compilation warning under -Warray-bounds by temporarily disabling the -Warray-bounds option.
* | Remove some tautological comparisons involving rlim_tPhilipp Stephani2017-06-141-2/+2
| | | | | | | | | | | | | | | | | | | | Clang on macOS warns about these with -Wtautological-compare. POSIX guarantees that rlim_t is unsigned (cf. http://pubs.opengroup.org/onlinepubs/009695399/basedefs/sys/resource.h.html), so these resource limits can never be negative. * src/emacs.c (main): Remove tautological comparisons.
* | Define --module-assertions only of modules are availablePhilipp Stephani2017-06-141-0/+6
|/ | | | | | | | Fixes Bug#27352. * src/emacs.c (usage_message, standard_args): Define --module-assertions only if Emacs has been compiled with module support.
* Port cleanup attribute to Oracle Studio 12.5Paul Eggert2017-06-132-4/+2
| | | | | | | | | | | * INSTALL (--with-modules): List cleanup attribute as prereq. * src/conf_post.h (__has_attribute_cleanup): Remove; no longer needed. * src/emacs-module.c (MODULE_SETJMP_1): Don’t attempt to verify (__has_attribute (cleanup)), as Oracle Studio 12.5 supports __has_attribute only inside preprocessor expressions. The C compiler should check the cleanup attribute in the next line anyway. (module_reset_handlerlist): Remove an unnecessary ‘const’ that causes Oracle Studio 12.5 to refuse to compile.
