* Update copyright year to 2020Paul Eggert2020-01-011-1/+1

* extern function cleanupPaul Eggert2019-08-241-1/+0
| | | | | | | | | | | | | Most of these functions can be static. A few are unused. * src/coding.c (encode_string_utf_8, decode_string_utf_8): Define only if ENABLE_UTF_8_CONVERTER_TEST, as they're not needed otherwise. * src/coding.c (encode_string_utf_8, decode_string_utf_8): * src/data.c (integer_mod): * src/fns.c (base64_encode_region_1, base64_encode_string_1): * src/ftfont.c (ftfont_get_fc_charset): Now static. * src/sysdep.c (verrprintf): Remove; unused.
* Fix recent changesEli Zaretskii2019-07-141-0/+1
| | | | * src/sysstdio.h: Include stdarg.h, for va_list.
* Use a better buffer size in emacs_perrorPaul Eggert2019-07-131-0/+5
| | | | | | * src/sysdep.c (emacs_perror): Since the buffer is for avoiding interleaving, size it via PIPE_BUF not BUFSIZ. * src/sysstdio.h (PIPE_BUF): Provide a default.
* Avoid interleaving stderr in a few casesPaul Eggert2019-07-131-0/+3
| | | | | | | | | | * src/sysdep.c (buferr): New static var. (init_standard_fds) [_PC_PIPE_BUF]: Initialize it. (errstream, errputc, verrprintf, errwrite): New functions. (close_output_streams): Check buferr status too. * src/xdisp.c: Include sysstdio.h instead of stdio.h. (message_to_stderr, vmessage): Use the new functions to avoid interleaving stderr.
* Use fewer locks when accessing stdioPaul Eggert2019-07-081-41/+1

* Don’t ignore stderr failure when ADDRESS_SANITIZERPaul Eggert2019-07-061-0/+1
| | | | | | | * src/emacs.c (close_output_streams): Move from here ... * src/sysdep.c: ... to here, where it really belongs anyway. When ADDRESS_SANITIZER, fflush stderr and check for ferror, to catch stderr output errors even in this case.

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-1/+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.
* Use unlocked stdio more systematicallyPaul Eggert2017-06-221-0/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This can improve performance significantly on stdio-bottlenecked code. E.g., make-docfile is 3x faster on my Fedora 25 x86-64 desktop. * admin/merge-gnulib (GNULIB_MODULES): Add unlocked-io. * lib-src/ebrowse.c, lib-src/emacsclient.c, lib-src/etags.c: * lib-src/hexl.c, lib-src/make-docfile.c, lib-src/movemail.c: * lib-src/profile.c, lib-src/update-game-score.c: Include unlocked-io.h instead of stdio.h, since these programs are single-threaded. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib/unlocked-io.h, m4/unlocked-io.m4: New files, copied from Gnulib. * src/charset.c, src/cm.c, src/emacs.c, src/image.c, src/keyboard.c: * src/lread.c, src/term.c: Include sysstdio.h, possibly instead of stdio.h, to define the unlocked functions if the system does not provide them. * src/charset.c, src/lread.c (getc_unlocked): Remove, since sysstdio.h now defines it if needed. * src/cm.c (cmputc, cmcheckmagic): * src/dispnew.c (update_frame, update_frame_with_menu) (update_frame_1, Fsend_string_to_terminal, Fding, bitch_at_user): * src/emacs.c (main, Fdump_emacs): * src/fileio.c (Fdo_auto_save, Fset_binary_mode): * src/image.c (slurp_file, png_read_from_file, png_load_body) (our_stdio_fill_input_buffer): * src/keyboard.c (record_char, kbd_buffer_get_event, handle_interrupt): * src/lread.c (readbyte_from_file): * src/minibuf.c (read_minibuf_noninteractive): * src/print.c (printchar_to_stream, strout) (Fredirect_debugging_output): * src/sysdep.c (reset_sys_modes, procfs_ttyname) (procfs_get_total_memory): * src/term.c (tty_ring_bell, tty_send_additional_strings) (tty_set_terminal_modes, tty_reset_terminal_modes) (tty_update_end, tty_clear_end_of_line, tty_write_glyphs) (tty_write_glyphs_with_face, tty_insert_glyphs) (tty_menu_activate): * src/xfaces.c (Fx_load_color_file): Use unlocked stdio when it should be safe. * src/sysstdio.h (clearerr_unlocked, feof_unlocked, ferror_unlocked) (fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked) (fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked) (putc_unlocked, putchar_unloced): Provide substitutes if not declared.
* Update copyright year to 2017Paul Eggert2016-12-311-1/+1

* Rework C source files to avoid ^(Paul Eggert2016-03-101-2/+2
| | | | | | | | Work around Bug#22884 by rewording comments and strings to avoid ‘(’ at the start of a line unless it starts a function. This change is a short-term hack; in the longer run we plan to fix cc-mode’s performance for C files that have ‘(’ at the start of a line in a comment or string.

* Make src headers idempotent and standalonePaul Eggert2015-10-161-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Redo src/*.h so that each include file is idempotent (that is, can be included multiple times with the latter inclusions having no effect) and standalone (that is, can be included by itself, with no include file other than config.h needed as a prerequisite). This is standard practice in GNU programs nowadays. * lwlib/lwlib-widget.h, src/buffer.h, src/category.h, src/character.h: * src/charset.h, src/coding.h, src/commands.h, src/disptab.h: * src/fontset.h, src/gnutls.h, src/indent.h, src/keymap.h, src/macros.h: * src/regex.h [emacs]: * src/syntax.h, src/systty.h, src/termhooks.h: Include lisp.h, for Lisp_Object. * src/buffer.h, src/category.h, src/cm.h, src/commands.h, src/disptab.h: * src/indent.h, src/intervals.h, src/keyboard.h, src/macros.h: * src/process.h, src/puresize.h, src/region-cache.h, src/syntax.h: * src/syssignal.h, src/sysstdio.h, src/systty.h, src/termchar.h: * src/termopts.h, src/tparam.h, src/unexec.h: Protect against multiple inclusion. * src/buffer.h: Include character.h, for STRING_CHAR. * src/emacsgtkfixed.h (struct frame): * src/fontset.h (struct face): * src/region-cache.h (struct buffer): * src/termhooks.h (struct glyph): * src/xsettings.h (struct x_display_info): Add possibly-forward decl. * src/syntax.h: Include buffer.h, for BVAR. * src/sysselect.h: Include lisp.h, for eassume. * src/termchar.h: Include <stdio.h>, for FILE. * src/widget.h: Include <X11/IntrinsicP.h>, for Widget. * src/xsettings.h: Include <X11/Xlib.h>, for XEvent.
* Simplify binary I/O configurationPaul Eggert2015-02-191-0/+29
| | | | | | | | | | | | * lib-src/etags.c: Include <sysstdio.h> rather than <stdio.h>. (process_file_name, analyze_regex): Use FOPEN_BINARY rather than hard-coded "b". * src/lread.c (Fload): Prefer FOPEN_TEXT and FOPEN_BINARY to #ifdef DOS_NT. * src/sysstdio.h: Add copyright notice. Include <fcntl.h>. (FOPEN_BINARY, FOPEN_TEXT): New macros. * src/xfaces.c (Fx_load_color_file): Use FOPEN_TEXT, since POSIX doesn't guarantee that "t" will work.
* Use emacs_open more consistently when opening files.Paul Eggert2013-07-051-0/+2
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.
