* Use unlocked stdio more systematicallyPaul Eggert2017-06-222-1/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Merge from gnulibPaul Eggert2017-06-171-2/+6
| | | | | | | This (and my previous patch) incorporate: 2017-06-17 diffseq: port to GCC 7 with --enable-gcc-warnings 2017-06-15 gettext-h: Update comment * lib/diffseq.h: Copy from gnulib.
* Add command to replace buffer contentsPhilipp Stephani2017-06-173-1/+602
| | | | | | | | | | | | | | | | | 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 Eggert2017-06-151-16/+11
| | | | | | | | | | * 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.
* Silence two Clang warnings by introducing additional local variablesPhilipp Stephani2017-06-131-11/+16
| | | | | | * lib/strftime.c (libc_hidden_def): * lib-src/make-docfile.c (put_filename): Introduce local variables to silence Clang warnings.

* Improve performance by avoiding strtoumaxPaul Eggert2017-06-014-73/+1
| | | | | | | | | | | | | | | | This made (string-to-number "10") 20% faster on my old desktop, an AMD Phenom II X4 910e running Fedora 25 x86-64. * admin/merge-gnulib (GNULIB_MODULES): Remove strtoumax. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib/strtoul.c, lib/strtoull.c, lib/strtoumax.c, m4/strtoull.m4: * m4/strtoumax.m4: Remove. * src/editfns.c (str2num): New function. (styled_format): Use it instead of strtoumax. Use ptrdiff_t instead of uintmax_t. Check for integer overflow. * src/lread.c (LEAD_INT, DOT_CHAR, TRAIL_INT, E_EXP): Move to private scope and make them enums. (string_to_number): Compute integer value directly during first pass instead of revisiting it with strtoumax later.

Use it to mark all switch cases that fall through. * src/editfns.c (styled_format): Use !, not ~, on bool. * src/gtkutil.c (xg_check_special_colors): When using sprintf, don’t trust Gtk to output colors in [0, 1] range. (xg_update_scrollbar_pos): Avoid use of possibly-uninitialized bool; this bug was actually caught by Clang. * src/search.c (boyer_moore): Tell GCC that CHAR_BASE, if nonzero, must be a non-ASCII character. * src/xterm.c (x_draw_glyphless_glyph_string_foreground): Tell GCC that glyph->u.glyphless.ch must be a character.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes some minor problems introduced in the recent switch to GNU Make, discovered by further testing. Without some of these changes 'make -j' would sometimes have race conditions caused by missing dependencies.

($(srcdir)/configure): Use plain ./autogen.sh, for consistency with other autogen.sh invocations. ($(srcdir)/src/stamp-h.in): Remove rule, as this file is no longer created. * Makefile.in (top_distclean): * src/Makefile.in (bootstrap-clean): No need to remove stamp-h1, as that was an Automake byproduct and Automake is no longer in use. * lib/Makefile.in, src/Makefile.in: (AUTOCONF_INPUTS, $(top_srcdir)/configure): Remove. (../config.status, Makefile): Simplify by limiting dependencies to files we care about and files in the repository, and by using just one file to represent the timestamps on multiple targets updated by the same rule. * autogen.sh: Do not create or use src/stamp-h.in. Instead, have 'find' test the two output files directly.

The Emacs build process uses Automake primarily because Emacs uses some Gnulib code and Gnulib formerly required Automake. Now that Gnulib no longer requires Automake, Emacs can stop using Automake and this should simplify Emacs maintenance in the future (Bug#26100). Although this patch may look long, most of it is generated automatically: the changes to build-aux/config.guess, build-aux/config.sub, build-aux/install-sh, and lib/gnulib.mk.in are all done by admin/merge-gnulib. * .gitignore: Remove build-aux/ar-lib, build-aux/compile, build-aux/config.guess, build-aux/config.sub, build-aux/depcomp, build-aux/install-sh, build-aux/missing, and lib/Makefile.in, as they are no longer built by autogen.sh. Add lib/gnulib.mk, as it is now built by 'configure'. Remove nt/gnulib.mk, as it is no longer built by 'make'. * INSTALL.REPO, README, admin/make-tarball.txt: Remove mention of Automake. * Makefile.in (AUTOCONF, AUTOMAKE, AUTOHEADER, ACLOCAL, lib) (AUTOCONF_INPUTS, ACLOCAL_PATH, ACLOCAL_INPUTS) ($(srcdir)/aclocal.m4, AUTOMAKE_INPUTS) ($(srcdir)/lib/Makefile.in, $(srcdir)/nt/gnulib.mk, am--refresh): Remove. ($(MAKEFILE_NAME)): Depend on lib/gnulib.mk.in. ($(srcdir)/configure, $(srcdir)/src/stamp-h.in) ($(srcdir)/src/config.in): Use autogen.sh instead of doing it by hand. * admin/merge-gnulib (AVOIDED_MODULES, avoided_flags)): New vars, to simplify processing of avoided modules. (GNULIB_TOOL_FLAGS): Move --avoid flags into AVOIDED_MODULES. Add --gnu-make, and change makefile name to gnulib.mk.in. Copy config.guess, config.sub, and install-sh too, since Automake no longer does that for us. * admin/notes/copyright: * admin/update_autogen (genfiles): Update list of files. Remove hack for nt/gnulib.mk, a file that is no longer needed. * autogen.sh (progs): Remove Automake. (automake_min): Remove. Build aclocal.m4 so that autoreconf need not use aclocal. * build-aux/config.guess, build-aux/config.sub: * build-aux/install-sh: New files, copied from Gnulib. These are now updated by admin/merge-gnulib instead by autogen.sh. * configure.ac (AC_PROG_MAKE_SET, ACLOCAL_PATH, AM_CONDITIONAL): Remove. (AM_INIT_AUTOMAKE, AM_SILENT_RULES): Remove call. (AC_PROG_CC_C_O): Call this instead of AM_PROG_CC_C_O. (BUILDING_FOR_WINDOWSNT, HYBRID_MALLOC_LIB): Remove; no longer needed. (--disable-silent-rules): New option, since Automake no longer does this for us. (AM_V, AM_DEFAULT_V): Set unconditionally, and do not bother with AM_SUBST_NOTMAKE. (AC_PROG_INSTALL): Add call. (MAKEINFO): Do not bother with the 'missing' program. (MAKEINFO, SYSTEM_TYPE): AC_SUBST. (AC_CONFIG_FILES): Add Makefile, lib/gnulib.mk. (SUBDIR_MAKEFILES): Remove duplication. * lib/Makefile.am: Remove, replacing with: * lib/Makefile.in: New file, with the old Makefile.am contents and with the following changes: (AUTOMAKE_OPTIONS, BUILT_SOURCES, CLEANFILES, EXTRA_DIST) (MOSTLYCLEANDIRS, MOSTLYCLEANFILES, noinst_LIBRARIES, SUFFIXES) (AM_CFLAGS, DEFAULT_INCLUDES, libegnu_a_SOURCES, libegnu_a_LIBADD) (EXTRA_libegnu_a_SOURCES, libegnu_a_SHORTNAME, libegnu_a_CPPFLAGS): Remove. (VPATH, abs_top_builddir, top_builddir, top_srcdir, all, AM_V_AR) (AM_V_CC, AM_V_GEN, AM_V_at, DEPDIR, DEPFLAGS, MKDEPDIR, SYSTEM_TYPE) (libgnu.a, libegnu.a, ETAGS, $(ETAGS), tags, TAGS, clean) (mostlyclean, distclean, bootstrap-clean, maintainer-clean): New macros and rules, since Automake no longer does them. Include ../nt/gnulib-cfg.mk if SYSTEM_TYPE is windows-nt, instead of including ../nt/gnulib.mk if BUILDING_FOR_WINDOWS_NT. Include dependency files if AUTO_DEPEND.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/unexw32.c (get_section_info): Make extra_bss_size be the maximum of extra_bss_size and extra_bss_size_static. This avoids computing the size of the output file smaller than it actually needs to be, which then causes copy_executable_and_dump_data to write beyond the requested size of the file mapping, thus relying on the OS roundup to page boundary to save us from ourselves. See http://lists.gnu.org/archive/html/emacs-devel/2016-12/msg00642.html for the details. * lib/stdio-impl.h: Revert the workaround fix of not including errno.h for MinGW.
