2020-06-20Add fallback for 24-bit terminal color via COLORTERM=truecolorJan Beich1-0/+9
* src/term.c (init_tty): When COLORTERM=truecolor is defined, override setaf/setab/colors terminfo capabilities with 24-bit color support. * doc/misc/efaq.texi (Colors on a TTY): Mention the possibility to enable 24-bit color via the COLORTERM environment variable. (Bug#41846) Copyright-paperwork-exempt: yes
2020-04-28Avoid crashes on TTY frames with over-long compositionsEli Zaretskii1-1/+1
* src/term.c (encode_terminal_code): Each character from an automatic composition is a multibyte character, so its multibyte representation can take up to MAX_MULTIBYTE_LENGTH bytes. Account for that when allocating storage for characters to be encoded. (Bug#40913)
2020-01-13Handle tab-bar clicks on a GPM-capable console.Juri Linkov1-0/+8
* src/term.c (handle_one_term_event): Call tty_handle_tab_bar_click. * src/xdisp.c (tty_handle_tab_bar_click): Force reset of up_modifier bit from the event modifiers. * lisp/tab-line.el (tab-line-tab-current): No need to use inverse-video on console/xterm because the selected tab already uses inverse-video.

Prevent mouse avoidance mode from interfering with 'mouse-drag-and-drop-region' (Bug#36269). * lisp/avoid.el (mouse-avoidance-ignore-p): Suspend avoidance when 'track-mouse' equals 'dropping'. * lisp/mouse.el (mouse-drag-and-drop-region): Set 'track-mouse' to 'dropping'. Continue reading events also when switching frames. * src/keyboard.c (Finternal_track_mouse): Rename from Ftrack_mouse. (some_mouse_moved): Return NULL also when mouse is not tracked. (show_help_echo, readable_events, kbd_buffer_get_event): Don't check whether mouse is tracked, some_mouse_moved does it now. (track_mouse): Rename variable from do_mouse_tracking. Adjust all users. In doc-string explain meanings of special values 'dragging' and 'dropping'. * src/nsterm.m (ns_mouse_position): During drag and drop consider last mouse frame only when there is no currently focused frame. * src/w32fns.c (w32_wnd_proc): Don't set mouse capture during a drag and drop operation. * src/w32term.c (w32_mouse_position): Track frame under mouse during mouse drag and drop.

All callers changed. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib/strnlen.c, m4/strnlen.m4: New files, copied from Gnulib. * lwlib/lwlib.c (lw_separator_p): * src/json.c (json_has_prefix): Use strncmp to avoid unecessary work with strlen + memcmp. * src/process.c (set_socket_option): Use SBYTES instead of strlen.
2019-06-20Remove no-longer-needed fflushes of stderrPaul Eggert1-1/+0
* src/gmalloc.c (mabort) [GC_MCHECK && !__GNU_LIBRARY__]: * src/term.c (vfatal): Remove fflush (stderr) when it is now a no-op because newline automatically flushes stderr.

2019-04-18Mark _Noreturn error functions as coldPaul Eggert1-4/+3
On my platform this made ‘make compile-always’ 1.3% faster. Suggested by Alex Gramiak in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00684.html * configure.ac (nw): Don’t use -Wsuggest-attribute=cold. * lib-src/make-docfile.c (write_globals): Mark noreturn functions as cold. * src/callproc.c (exec_failed): * src/data.c (wrong_length_argument, wrong_type_argument): * src/emacs-module.c (module_abort): * src/emacs.c (terminate_due_to_signal): * src/eval.c (unwind_to_catch): * src/image.c (my_png_error, my_error_exit): * src/json.c (json_out_of_memory, json_parse_error): * src/keyboard.c (quit_throw_to_read_char, user_error): * src/lisp.h (die, wrong_type_argument, wrong_choice) (args_out_of_range, args_out_of_range_3, circular_list) (buffer_overflow, memory_full, buffer_memory_full) (string_overflow, xsignal, xsignal0, xsignal1, xsignal2) (xsignal3, signal_error, overflow_error, error, verror) (nsberror, report_file_errno, report_file_error) (report_file_notify_error, terminate_due_to_signal) (emacs_abort, fatal): * src/lread.c (load_error_old_style_backquotes) (end_of_file_error, invalid_syntax): * src/pdumper.c (error_unsupported_dump_object): * src/puresize.h (pure_write_error): * src/search.c (matcher_overflow): * src/sound.c (sound_perror, alsa_sound_perror): * src/sysdep.c (handle_arith_signal): * src/systime.h (time_overflow): * src/term.c (maybe_fatal, vfatal): * src/textprop.c (text_read_only): * src/timefns.c (invalid_time_zone_specification) (time_error, invalid_hz): * src/xterm.c (x_connection_closed): Use AVOID instead of _Noreturn void, so that it’s marked cold. * src/conf_post.h (__has_attribute_cold) [!__has_attribute]: New macro.

2019-02-27DEFVAR_INT variables are now intmax_tPaul Eggert1-1/+3
Formerly they were fixnums, which led to problems when dealing with values that might not fit on 32-bit platforms, such as string-chars-consed or floats_consed. 64-bit counters should be good enough for these (for a while, anyway...). While we’re at it, fix some unlikely integer overflow bugs that have been in the code for a while. * lib-src/make-docfile.c (write_globals): * src/data.c (do_symval_forwarding, store_symval_forwarding): * src/eval.c (restore_stack_limits, call_debugger): * src/frame.h (struct frame.cost_calculation_baud_rate): * src/keyboard.c (last_auto_save, bind_polling_period, read_char): * src/lisp.h (struct Lisp_Intfwd.intvar): * src/lread.c (defvar_int): * src/pdumper.c (dump_fwd_int): * src/thread.h (struct thread_state.m_lisp_eval_depth): * src/undo.c (truncate_undo_list): * src/xselect.c (wait_for_property_change) (x_get_foreign_selection): * src/xterm.c (x_emacs_to_x_modifiers): DEFVAR_INT variables now have the C type intmax_t, not EMACS_INT. * src/data.c (store_symval_forwarding): * src/gnutls.c (Fgnutls_boot): * src/keyboard.c (bind_polling_period): * src/macros.c (pop_kbd_macro, Fexecute_kbd_macro): * src/undo.c (truncate_undo_list): Allow any integer that fits into intmax_t, instead of requiring it to be a Lisp fixnum. * src/dispnew.c (update_window): * src/frame.c (x_figure_window_size): * src/gnutls.c (init_gnutls_functions) (emacs_gnutls_handle_error): * src/keyboard.c (make_lisp_event): * src/nsterm.m (ns_dumpglyphs_image): * src/profiler.c (make_log): * src/scroll.c (calculate_scrolling) (calculate_direct_scrolling): * src/termcap.c (tputs): * src/xterm.c (x_draw_image_relief): Avoid implementation-defined behavior on conversion of out-of-range integers. * src/eval.c (when_entered_debugger): Now intmax_t.

Include intprops.h. * src/window.c (sanitize_next_screen_context_lines): New function. (window_scroll_pixel_based, window_scroll_line_based): Use it to avoid signed integer overflow.
2019-02-23Don’t assume timersub and gettimeofdayPaul Eggert1-13/+7
POSIX does not specify timersub, and marks gettimeofday as obsolescent. Avoid porting problems by using timespec.h functions instead. * src/editfns.c: Include systime.h instead of sys/time.h. (EXTRA_CONTEXT_FIELDS): Replace start and max_secs with time_limit. All uses changed. This removes the need to call gettimeofday or timersub. * src/term.c (timeval_to_Time): Remove. Replace all uses with ... (current_Time): ... this new function, removing the need to call gettimeofday.
2019-02-01Rename CANNOT_DUMP to HAVE_UNEXECPaul Eggert1-1/+2
* configure.ac (CANNOT_DUMP): Remove. All uses removed, or changed to the negative of with_unexec. (HAVE_UNEXEC): New macro. All uses of CANNOT_DUMP changed to the negative of this macro.

2018-12-09Add make_vector and make_nil_vectorPaul Eggert1-9/+6
This makes the callers a bit easier to read, and doubtless improves efficiency very slightly. It also simplifies possible future changes to allow bignum indexes to buffers. * src/alloc.c (allocate_vectorlike): Prefer ptrdiff_t to size_t when either will do. (make_vector): New function. (Fmake_vector): Use it. * src/buffer.c (syms_of_buffer): * src/bytecode.c (syms_of_bytecode): * src/category.c (Fmake_category_table, init_category_once): * src/ccl.c (syms_of_ccl): * src/character.c (syms_of_character): * src/charset.c (Fdefine_charset_internal) (Ffind_charset_region, Ffind_charset_string): * src/chartab.c (copy_char_table): * src/coding.c (Fdefine_coding_system_internal, syms_of_coding): * src/composite.c (get_composition_id, Fcomposition_get_gstring): * src/composite.h (LGLYPH_NEW): * src/fns.c (concat, Flocale_info, make_hash_table): * src/font.c (font_otf_ValueRecord, font_otf_anchor) (build_style_table, syms_of_font): * src/fontset.c (RFONT_DEF_NEW, fontset_find_font) (dump_fontset, syms_of_fontset): * src/image.c (xpm_make_color_table_v): * src/keyboard.c (modify_event_symbol, menu_bar_items) (parse_menu_item, parse_tool_bar_item, init_tool_bar_items) (syms_of_keyboard): * src/keymap.c (Fdefine_key, describe_map, describe_vector): * src/lread.c (read_vector): * src/macfont.m (macfont_shape): * src/menu.c (init_menu_items): * src/nsfns.m (ns_make_monitor_attribute_list): * src/process.c (conv_sockaddr_to_lisp, network_interface_info): * src/profiler.c (make_log): * src/window.c (Fcurrent_window_configuration): * src/xdisp.c (with_echo_area_buffer_unwind_data) (format_mode_line_unwind_data): * src/xfaces.c (Finternal_make_lisp_face) (Fface_attributes_as_vector): * src/xfns.c (x_make_monitor_attribute_list) (Fx_display_monitor_attributes_list): * src/xfont.c (syms_of_xfont): * src/xselect.c (x_handle_dnd_message): * src/xwidget.c (save_script_callback): Prefer make_nil_vector (N) to Fmake_vector (make_fixnum (N), Qnil). * src/callint.c (Fcall_interactively): * src/charset.c (load_charset_map): * src/chartab.c (Fmake_char_table, uniprop_encode_value_numeric): * src/composite.c (get_composition_id) * src/dispnew.c (Fframe_or_buffer_changed_p) (syms_of_display): * src/fns.c (make_hash_table, maybe_resize_hash_table): * src/font.c (font_style_to_value): * src/fontset.c (FONTSET_ADD, fontset_add): * src/json.c (json_to_lisp): * src/keymap.c (syms_of_keymap): * src/lread.c (init_obarray): * src/profiler.c (make_log, Fprofiler_cpu_log): * src/term.c (term_get_fkeys_1): Prefer make_vector (N, V) to Fmake_vector (make_fixnum (N), V). * src/font.c (build_style_table): * src/macfont.m (macfont_shape): * src/process.c (conv_sockaddr_to_lisp, network_interface_info): Prefer make_uninit_vector if the vector will be initialized soon. * src/lisp.h (make_nil_vector): New function.

2018-06-02Fix display of TABs in hscrolled windows with line numbersEli Zaretskii1-2/+2
* src/dispextern.h (struct it): New members tab_offset and line_number_produced_p. * src/xdisp.c (display_line): Don't set row->x to a negative value if line numbers are being displayed. (Bug#30582) Reset the line_number_produced_p flag before laying out the glyph row.

2018-02-10Support standard Terminfo direct mode terminalsRami Ylimäki1-1/+9
Latest Terminfo introduces terminal definitions that support direct color mode. The "Co"/"colors" capability is set to 0x1000000 on these terminals and Emacs is already compatible with them. However, if used Terminfo library hasn't been compiled with 32-bit value support, "Co"/"colors" is truncated to 0x7fff. In this case direct color mode support can be detected from the "RGB" capability flag. There are some minor problems if the color count isn't corrected from 0x7fff. First eight standard colors defined in xterm-standard-colors are shown correctly. However, their RGB values match the terminal settings, not the RGB values defined in xterm-standard-colors. Bright versions of these colors are shown incorrectly. They are interpreted as pixels #000008 - #000015, which are very dark shades of blue. * src/term.c (init_tty): Force terminal color count to 0x1000000 if "RGB" capability is present. * src/tparam.h: Define prototype for tigetflag. (Bug#30308) * doc/misc/efaq.texi (Colors on a TTY): Add information about direct mode terminals supported by Terminfo.

2017-09-13Prefer HTTPS to FTP and HTTP in documentationPaul Eggert1-1/+1
Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.
2017-09-08Avoid compiler warnings on MS-Windows with GCC 6 and 7Eli Zaretskii1-1/+1

These two changes fix horizontal scrolling when line numbers are displayed. But there's still a bug: the horizontal shift of lines that begin with a TAB is different from the rest. * src/xdisp.c (move_it_in_display_line_to): Call should_produce_line_number to determine whether a line number should be produced for this screen line.

2016-09-30Limit <config.h>’s includesPaul Eggert1-0/+1
This follows up on recent problems with the fact that config.h includes stdlib.h etc.; some files need to include stdlib.h later. config.h generally should limit itself to includes that are universally safe; outside of MS-Windows, only stdbool.h makes the cut among the files currently included. So, move the other includes to just the files that need them (Bug#24506). * configure.ac (config_opsysfile): Remove, as this generic hook is no longer needed. * lib-src/etags.c, src/unexmacosx.c, src/w32.c, src/w32notify.c: * src/w32proc.c (_GNU_SOURCE): Remove, as it’s OK for config.h to do this now. * src/conf_post.h: Include <ms-w32.h>, instead of the generic config_opsysfile, for simplicity as this old way of configuring is now done only for the MS-Windows port. Do not include <ms-w32.h> if DEFER_MS_W32_H, for the benefit of the few files that want its effects later. Do not include <alloca.h>, <string.h>, or <stdlib.h>. Other files modified to include these headers as needed, or to not include headers that are no longer needed. * src/lisp.h: Include <alloca.h> and <string.h> here, since some of the inline functions need them. * src/regex.c: Include <alloca.h> if not emacs. (If emacs, we can rely on SAFE_ALLOCA.) There is no longer any need to worry about HAVE_ALLOCA_H. * src/unexmacosx.c: Rely on config.h not including stdlib.h. * src/w32.c, src/w32notify.c, src/w32proc.c (DEFER_MS_W32_H): Define before including <config.h> first, and include <ms-w32.h> after the troublesome headers.

All uses changed. (BITS_PER_CHAR): Remove; all uses replaced by CHAR_BIT. This must be the same as CHAR_WIDTH and avoids confusion with Elisp char-width, which counts columns not bits. (BITS_PER_SHORT): Remove; all uses replaced by SHRT_WIDTH. (BITS_PER_LONG): Remove; all uses replaced by LONG_WIDTH. * src/lread.c: Do not include limits.h since CHAR_BIT is no longer used directly.

* src/w32proc.c (sys_signal): Don't reject SIGINT, as it is supported by MS runtime. * src/term.c (DEV_TTY): Move from here ... * src/conf_post.h (DEV_TTY): ... to here. Separate definitions for WINDOWSNT and for the rest. * src/keyboard.c (handle_interrupt_signal): Use DEV_TTY instead of a literal "/dev/tty". * etc/NEWS: Mention the behavior change.
2016-07-25‘signal’ no longer returnsPaul Eggert1-1/+1
Although for decades ‘signal’ has been documented to not return, a corner case in the Lisp debugger causes ‘signal’ to return. Remove the corner case and adjust Emacs internals accordingly. An alternative would be to document the corner case, but this would complicate the Lisp API unnecessarily. (Bug#24047) * src/eval.c (signal_or_quit): New function, with most of the old contents of Fsignal. (quit): New function, which uses signal_or_quit and which might return. All keyboard-based callers of Fsignal (Qquit, Qnil) changed to use this new function instead. (Fsignal): Use signal_or_quit. Now _Noreturn. All callers changed. (xsignal): Move to lisp.h. * src/lisp.h (xsignal): Now an inline function, as it's now just an alias for Fsignal.
2016-07-02Fix cursor positioning on TTY frames after stretch glyphEli Zaretskii1-2/+8
* src/term.c (append_glyph, append_composite_glyph) (append_glyphless_glyph): Set the avoid_cursor_p and multibyte_p members of the produced 'struct glyph'. Fixes cursor positioning on the first character after a stretch glyph produced from line-prefix, wrap-prefix, etc. on TTY frames.
