2023-05-17Prefer C23 ckd_* to Gnulib *_WRAPV macrosPaul Eggert
C23 has added ckd_add etc. macros with functionality equivalent to the older Gnulib INT_ADD_WRAPV macros, so switch to the more-standard names. * admin/merge-gnulib (GNULIB_MODULES): Add stdckdint. This merely makes the dependency explicit, as we were already using this Gnulib module indirectly. * lib-src/etags.c, src/lisp.h: Include stdckdint.h. * lib-src/etags.c (xnmalloc, xnrealloc): * src/alloc.c (xnmalloc, xnrealloc, xpalloc, Fmake_string) (mark_memory): * src/bignum.c (emacs_mpz_pow_ui): * src/buffer.c (record_overlay_string, overlay_strings): * src/bytecode.c (exec_byte_code): * src/casefiddle.c (do_casify_multibyte_string): * src/ccl.c (ccl_driver, Fccl_execute_on_string): * src/character.c (char_width, c_string_width) (lisp_string_width, count_size_as_multibyte) (string_escape_byte8): * src/cmds.c (internal_self_insert): * src/coding.c (coding_alloc_by_realloc, produce_chars): * src/data.c (arith_driver): * src/dispnew.c (realloc_glyph_pool, init_display_interactive): * src/doprnt.c (parse_format_integer): * src/editfns.c (Freplace_buffer_contents, str2num) (styled_format): * src/emacs-module.c (module_global_reference_p) (module_make_global_ref, module_funcall): * src/eval.c (max_ensure_room): * src/fileio.c (blocks_to_bytes): * src/fns.c (Ffillarray): * src/font.c (font_intern_prop): * src/frame.c (check_frame_pixels): * src/gnutls.c (gnutls_hex_string, gnutls_symmetric_aead): * src/gtkutil.c (get_utf8_string): * src/haikuterm.c (haiku_term_init): * src/image.c (xbm_scan, image_to_emacs_colors) (image_detect_edges, png_load_body): * src/keyboard.c (Frecursion_depth): * src/keymap.c (Flookup_key, Fkey_description): * src/lisp.h (modiff_incr, SAFE_ALLOCA_LISP_EXTRA): * src/lread.c (read_bool_vector): * src/pgtkterm.c (pgtk_term_init): * src/regex-emacs.c (regex_compile): * src/term.c (encode_terminal_code): * src/termcap.c (tputs): * src/textconv.c (textconv_query): * src/timefns.c (timespec_ticks, lisp_time_hz_ticks) (Fdecode_time, check_tm_member): * src/tparam.c (tparam1): * src/w32term.c (w32_initialize_display_info): * src/xdisp.c (fill_column_indicator_column, decode_mode_spec): * src/xselect.c (selection_data_size, x_property_data_to_lisp): * src/xsmfns.c (smc_save_yourself_CB): * src/xterm.c (xm_setup_dnd_targets, x_sync_get_monotonic_time) (x_sync_current_monotonic_time, x_sync_note_frame_times) (x_display_set_last_user_time, x_term_init): Prefer the C23 stdckdint macros to their Gnulib intprops.h counterparts, since C23 is standard.

2019-02-27DEFVAR_INT variables are now intmax_tPaul Eggert
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.

2017-09-13Prefer HTTPS to FTP and HTTP in documentationPaul Eggert
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.

2013-07-11Fix races with threads and file descriptors.Paul Eggert

(emacs_close): Use it. This should fix the races on GNU/Linux and on AIX and on future platforms that support POSIX_CLOSE_RESTART, and it should avoid closing random victim file descriptors on other platforms.
2013-07-10* sysdep.c, term.c, termcap.c, terminal.c: Integer-related minor fixes.Paul Eggert
* sysdep.c (emacs_get_tty): Return void, since nobody uses the value. (emacs_set_tty): Now static. * sysdep.c (emacs_set_tty, tabs_safe_p, emacs_close): * term.c (tty_capable_p, tty_default_color_capabilities) (get_tty_terminal, term_mouse_movement) (handle_one_term_event, init_tty, maybe_fatal): * termcap.c (tgetst1, struct termcap_buffer, valid_filename_p) (tgetent, scan_file, name_match, compare_contin): * terminal.c (get_terminal): Use bool for boolean. * sysdep.c (init_system_name): Don't overflow stack on huge hostname. Prefer char to unsigned char if either will do. * term.c (OUTPUT, turn_on_face): Omit unnecessary casts to int. (tty_write_glyphs): Prefer int to unsigned. (produce_glyphless_glyph): Remove 2nd (unused) int arg. All callers changed. * termcap.c (tprint, main) [TEST]: Remove non-working test.
2013-07-05Use emacs_open more consistently when opening files.Paul Eggert
This handles EINTR more consistently now, and makes it easier to introduce other uniform changes to file descriptor handling. * src/systdio.h: New file. * src/buffer.c (mmap_init): * cygw32.c (chdir_to_default_directory): * dispnew.c (Fopen_termscript): * emacs.c (Fdaemon_initialized): * fileio.c (Fdo_auto_save): * image.c (slurp_file, png_load_body, jpeg_load_body): * keyboard.c (Fopen_dribble_file): * lread.c (Fload): * print.c (Fredirect_debugging_output): * sysdep.c (get_up_time, procfs_ttyname, procfs_get_total_memory): * termcap.c (tgetent): * unexaix.c, unexcoff.c (unexec, adjust_lnnoptrs): * unexcw.c, unexelf.c, unexhp9k800.c, unexmacosx.c (unexec): * w32term.c (w32_initialize) [CYGWIN]: * xfaces.c (Fx_load_color_file): Use emacs_open instead of plain open, and emacs_fopen instead of plain fopen. * dispnew.c, fileio.c, image.c, keyboard.c, lread.c, print.c, sysdep.c: * xfaces.c: Include sysstdio.h rather than stdio.h, for emacs_fopen. * callproc.c (default_output_mode): New constant. (Fcall_process): Use it to call emacs_open instead of plain creat. * dispnew.c (Fopen_termscript): Fix minor race in opening termscript. * sysdep.c (emacs_open): Add commentary and don't call file name "path". (emacs_fopen): New function. * unexaix.c, unexcoff.c, unexelf.c, unexhp9k800.c, unexmacosx.c: Include <lisp.h>, for emacs_open. * unexelf.c (fatal): Remove decl; not needed with <lisp.h> included.
2013-02-02Avoid encoding file names run through dostounix_filename on MS-Windows.Eli Zaretskii

[WINDOWSNT]: Downcase file names if w32-downcase-file-names is non-nil. (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment variables, as egetenv is case-insensitive for DOS_NT. src/dired.c (file_name_completion): Don't call Fdirectory_file_name with an encoded file name. src/w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust calls to dostounix_filename. src/w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename. src/unexw32.c (unexec): Adjust call to dostounix_filename. src/termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename. src/emacs.c (decode_env_path) [DOS_NT]: Adjust call to dostounix_filename. src/callproc.c (Fcall_process) [MSDOS]: Adjust call to dostounix_filename.

2012-09-15Port better to POSIX hosts lacking _setjmp.Paul Eggert
* configure.ac (HAVE__SETJMP, HAVE_SIGSETJMP): New symbols. (_setjmp, _longjmp): Remove. * src/lisp.h: Include <setjmp.h> here, since we use its symbols here. All instances of '#include <setjmp.h>' removed, if the only reason for the instance was because "lisp.h" was included. (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols. Unless otherwise specified, replace all uses of jmp_buf, _setjmp, and _longjmp with the new symbols. Emacs already uses _setjmp if available, so this change affects only POSIXish hosts that have sigsetjmp but not _setjmp, such as some versions of Solaris and Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.) * src/image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros. (png_load_body) [HAVE_PNG]: (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]: (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]: Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp, since PNG requires jmp_buf. This is the only exception to the general rule that we now use sys_setjmp and sys_longjmp. This exception is OK since this code does not change the signal mask or longjmp out of a signal handler. Fixes: debbugs:12446
2012-07-05More xmalloc and related cleanup.Paul Eggert
* alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c: * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c: * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c: * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c: * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c: * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c: * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c: * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c: * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c: * xterm.c: Omit needless casts involving void * pointers and allocation. Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))", as the former is more robust if P's type is changed. Prefer xzalloc to xmalloc + memset 0. Simplify malloc-or-realloc to realloc. Don't worry about xmalloc returning a null pointer. Prefer xstrdup to xmalloc + strcpy. * editfns.c (Fmessage_box): Grow message_text by at least 80 when growing it. * keyboard.c (apply_modifiers_uncached): Prefer local array to alloca of a constant.
