2020-06-27Use getrandom syscall for noncesPaul Eggert1-26/+6
* admin/merge-gnulib (GNULIB_MODULES): Add getrandom. * doc/lispref/text.texi (Format of GnuTLS Cryptography Inputs): Don’t say that iv-auto uses GNUTLS_RND_NONCE. Also, don’t say that it returns the IV’s actual value, as it never has done that. * src/fns.c, src/sysdep.c: Include sys/random.h, for getrandom. * src/fns.c (Fsecure_hash_algorithms): Use getrandom so that this function does not depend on HAVE_GNUTLS3. * src/sysdep.c: Do not include <gnutls/crypto.h>. (random_seed) [HAVE_LRAND48]: Can be long int now. (init_random) [!WINDOWSNT]: Use getrandom syscall instead of opening /dev/urandom, as this works even on GNU/Linux hosts that lack /dev/urandom. Don’t bother with gnutls_rnd as it’s not needed now that we have getrandom.
2020-05-30Remove private prototype for 'execve' and its uses in MinGW buildEli Zaretskii1-0/+3
* src/sysdep.c (emacs_exec_file): Don't compile this function anymore on WINDOWSNT, since it is not used there. This function was the only reason for having 'execve' prototype in ms-w32.h. * nt/inc/ms-w32.h (execve): Remove prototype and the MinGW64 vs ming.org mess that it causes.
2020-04-17Prefer more inline functions in character.hPaul Eggert1-4/+10
* src/buffer.h (fetch_char_advance, fetch_char_advance_no_check) (buf_next_char_len, next_char_len, buf_prev_char_len) (prev_char_len, inc_both, dec_both): New inline functions, replacing the old character.h macros FETCH_CHAR_ADVANCE, FETCH_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS, INC_POS, BUF_DEC_POS, DEC_POS, INC_BOTH, DEC_BOTH respectively. All callers changed. These new functions all assume buffer primitives and so need to be here rather than in character.h. * src/casefiddle.c (make_char_unibyte): New static function, replacing the old MAKE_CHAR_UNIBYTE macro. All callers changed. (do_casify_unibyte_string): Use SINGLE_BYTE_CHAR_P instead of open-coding it. * src/ccl.c (GET_TRANSLATION_TABLE): New static function, replacing the old macro of the same name. * src/character.c (string_char): Omit 2nd arg. 3rd arg can no longer be NULL. All callers changed. * src/character.h (SINGLE_BYTE_CHAR_P): Move up. (MAKE_CHAR_UNIBYTE, MAKE_CHAR_MULTIBYTE, PREV_CHAR_BOUNDARY) (STRING_CHAR_AND_LENGTH, STRING_CHAR_ADVANCE) (FETCH_STRING_CHAR_ADVANCE) (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE) (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, FETCH_CHAR_ADVANCE) (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, INC_BOTH) (DEC_BOTH, BUF_INC_POS, BUF_DEC_POS): Remove. (make_char_multibyte): New static function, replacing the old macro MAKE_CHAR_MULTIBYTE. All callers changed. (CHAR_STRING_ADVANCE): Remove; all callers changed to use CHAR_STRING. (NEXT_CHAR_BOUNDARY): Remove; it was unused. (raw_prev_char_len): New inline function, replacing the old PREV_CHAR_BOUNDARY macro. All callers changed. (string_char_and_length): New inline function, replacing the old STRING_CHAR_AND_LENGTH macro. All callers changed. (STRING_CHAR): Rewrite in terms of string_char_and_length. (string_char_advance): New inline function, replacing the old STRING_CHAR_ADVANCE macro. All callers changed. (fetch_string_char_advance): New inline function, replacing the old FETCH_STRING_CHAR_ADVANCE macro. All callers changed. (fetch_string_char_as_multibyte_advance): New inline function, replacing the old FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE macro. All callers changed. (fetch_string_char_advance_no_check): New inline function, replacing the old FETCH_STRING_CHAR_ADVANCE_NO_CHECK macro. All callers changed. * src/regex-emacs.c (HEAD_ADDR_VSTRING): Remove; no longer used. * src/syntax.c (scan_lists): Use dec_bytepos instead of open-coding it. * src/xdisp.c (string_char_and_length): Rename from string_char_and_length to avoid name conflict with new function in character.h. All callers changed.
2020-03-07Add ‘nofollow’ flag to set-file-timesPaul Eggert1-15/+0
This is a companion to the recent set-file-modes patch. It adds support for a ‘nofollow’ flag to set-file-times (Bug#39773). Like the set-file-modes patch, it needs work in the w32 port. * admin/merge-gnulib (GNULIB_MODULES): Add futimens, utimensat. Remove utimens. * doc/lispref/files.texi (Changing Files): * etc/NEWS: Mention the change. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lisp/files.el (copy-directory): * lisp/gnus/gnus-cloud.el (gnus-cloud-replace-file): * lisp/net/tramp-adb.el (tramp-adb-handle-copy-file): * lisp/net/tramp-smb.el (tramp-smb-handle-copy-file): * lisp/tar-mode.el (tar-copy): * test/lisp/filenotify-tests.el (file-notify-test03-events): * test/lisp/files-tests.el: (files-tests-file-name-non-special-set-file-times): * test/lisp/net/tramp-tests.el (tramp-test22-file-times): When setting file times, avoid following symbolic links when the file is not supposed to be a symbolic link. * lib/futimens.c, lib/utimensat.c, m4/futimens.m4, m4/utimensat.m4: New files, copied from Gnulib. * lisp/gnus/gnus-cloud.el (gnus-cloud-replace-file): When creating a file that is not supposed to exist already, use the excl flag to check this. * lisp/net/tramp-adb.el (tramp-adb-handle-set-file-times): * lisp/net/tramp-sh.el (tramp-sh-handle-set-file-times): * lisp/net/tramp-sudoedit.el (tramp-sudoedit-handle-set-file-times): Accept an optional FLAG arg that is currently ignored, and add a FIXME comment for it. * lisp/net/tramp-gvfs.el (tramp-gvfs-handle-set-file-times): * src/fileio.c (Fset_file_times): Support an optional FLAG arg. * src/fileio.c (Fcopy_file): Use futimens instead of set_file_times, as it’s simpler and is a POSIX API. * src/sysdep.c (set_file_times): Move from here ... * src/w32.c (set_file_times): ... to here, and make it static, since it is now used only in w32.c. Presumably w32.c should also add support for futimens and utimensat (the POSIX APIs, which Emacs now uses) and it can remove fdutimens (the Gnulib API, which Emacs no longer uses).
2020-01-20Work better if stat etc. are interruptedPaul Eggert1-5/+31
Quit or retry if fstat, lstat, stat or openat fail with EINTR. This should fix some bugs on platforms where accessing files via NFS can fail that way (Bug#9256). * src/dired.c (file_attributes): * src/fileio.c (file_directory_p) [O_PATH]: Use emacs_openat instead of openat. * src/dired.c (file_attributes): Use emacs_fstatat instead of fstatat. * src/fileio.c (barf_or_query_if_file_exists, Frename_file): * src/filelock.c (rename_lock_file): Use emacs_fstatat instead of lstat. * src/fileio.c (file_directory_p, Ffile_regular_p, Ffile_modes) (Ffile_newer_than_file_p, Fverify_visited_file_modtime) (Fset_visited_file_modtime, auto_save_1): * src/lread.c (Fload): * src/sysdep.c (get_current_dir_name_or_unreachable): Use emacs_fstatat instead of stat. * src/sysdep.c (emacs_fstatat, emacs_openat): New functions. (emacs_open): Redo in terms of emacs_open.
2019-12-31Assume C99-style ‘long long’Paul Eggert1-6/+1
Now that Gnulib assumes ‘long long’, it is a good time to clean out old cruft porting to pre-C99 compilers that lack it. * src/data.c (ULL_WIDTH, ULL_MAX): Remove. All uses replaced by ULLONG_WIDTH, ULLONG_MAX. (bits_word_to_host_endian): Assume ‘unsigned long long’. By the way, the old code had a performance typo: it used HAVE_UNSIGNED_LONG_LONG where it should have used HAVE_UNSIGNED_LONG_LONG_INT. * src/sysdep.c (ULLONG_MAX): Remove, as lib/limits.h does this now. (time_from_jiffies) [GNU_LINUX]: Assume ‘long long’.
2020-01-01Update copyright year to 2020Paul Eggert1-1/+1
Run "TZ=UTC0 admin/update-copyright $(git ls-files)".
2019-11-20* src/sysdep.c: Improve comment wording.Paul Eggert1-1/+1
2019-11-19Make .pdmp file more reproduciblePaul Eggert1-2/+5
Problem reported by Ulrich Müller <https://lists.gnu.org/r/emacs-devel/2019-11/msg00757.html> and diagnosed by Andreas Schwab <https://lists.gnu.org/r/emacs-devel/2019-11/msg00774.html>. * src/sysdep.c (maybe_disable_address_randomization): Disable ASLR if any kind of dumping, instead of merely if unexec dumping. Omit first arg for simplicity; all uses changed.
2019-08-24extern function cleanupPaul Eggert1-6/+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.
2019-07-13Avoid interleaving stderr lines when shutting downPaul Eggert1-1/+1
* src/emacs.c (shut_down_emacs) [!DOS_NT]: Avoid interleaving to stderr in the usual case, by using a single write and by appending a newline. * src/sysdep.c (emacs_backtrace) [HAVE_BACKTRACE_SYMBOLS_FD]: Omit newline since shut_down_emacs now does that.
2019-07-13Use a better buffer size in emacs_perrorPaul Eggert1-2/+2
* 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.
2019-07-13Avoid interleaving stderr in a few casesPaul Eggert1-3/+56
* 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.
2019-07-08Use fewer locks when accessing stdioPaul Eggert1-6/+6
* src/alloc.c, src/bidi.c, src/emacs-module.c, src/pdumper.c: * src/regex-emacs.c, src/unexhp9k800.c, src/unexmacosx.c: * src/widget.c, src/xdisp.c, src/xselect.c, src/xterm.c: Include sysstdio.h instead of stdio.h, to avoid locking stdio streams in many cases. * src/alloc.c (test_setjmp): * src/bidi.c (bidi_dump_cached_states): * src/cm.c (calccost): * src/dispnew.c (init_display_interactive): * src/emacs.c (main): * src/image.c (convert_mono_to_color_image): * src/minibuf.c (read_minibuf_noninteractive): * src/nsfont.m (ns_descriptor_to_entity) (ns_dump_glyphstring): * src/nsterm.h (NSTRACE_MSG_NO_DASHES): * src/nsterm.m (ns_mouse_position) (sendEvent:, keyDown:, performDragOperation:): * src/pdumper.c (dump_fingerprint, print_paths_to_root_1): * src/print.c (debug_print): * src/regex-emacs.c (debug_putchar, print_fastmap) (print_partial_compiled_pattern, print_compiled_pattern) (print_double_string, regex_compile): * src/term.c (vfatal): * src/unexhp9k800.c (read_header): * src/unexmacosx.c (unexec_error): * src/widget.c (EmacsFrameInitialize): * src/xdisp.c (message_to_stderr, vmessage, dump_glyph_row) (Fdump_glyph_matrix, Fdump_frame_glyph_matrix, dump_glyph_string): * src/xfaces.c (Fdump_colors, Fdump_face): * src/xselect.c (x_clipboard_manager_error_2): * src/xterm.c (x_initialize): * src/xwidget.c (WEBKIT_FN_INIT): Prefer unlocked calls like fputs to locked calls like fprintf. * src/charset.c (read_hex): * 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/emacs-module.c (module_abort): * src/fileio.c (Fdo_auto_save): * 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_stdio, read1): * src/minibuf.c (read_minibuf_noninteractive): * src/print.c (printchar_to_stream, strout) (Fredirect_debugging_output): * src/sysdep.c (reset_sys_modes, close_output_streams) (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): Simplify by using ordinary calls like putc to explicitly-unlocked calls like putc_unlocked, since the ordinary calls are now unlocked anyway. * src/emacs.c (main, Fdump_emacs): * src/pdumper.c (Fdump_emacs_portable): Coalesce adjacent printfs. * src/nsterm.h: Include sysstdio.h as this file’s macros rely on it. * src/regex-emacs.c (print_compiled_pattern): Omit redundant fflush. * src/sysstdio.h: Include unlocked-io.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_unlocked): Remove these macros; now done by unlocked-io.h. * src/xwidget.c: Include sysstdio.h.
2019-07-07Remove printmax_t etc.Paul Eggert1-4/+4
printmax_t etc. were needed only for platforms that lacked support for printing intmax_t. These platforms are now so obsolete that they are no longer practical porting targets. * src/image.c (gs_load): Fix unlikely buffer overrun discovered while making these changes. It was introduced in 2011-07-17T00:34:43!eggert@cs.ucla.edu. * src/lisp.h (printmax_t, uprintmax_t, pMd, pMu, pMx): Remove. All uses replaced by their standard counterparts intmax_t, uintmax_t, PRIdMAX, PRIuMAX, PRIxMAX.
2019-07-06Don’t ignore stderr failure when ADDRESS_SANITIZERPaul Eggert1-0/+20
* 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.
2019-06-25Prefer PATH_MAX to MAXPATHLENPaul Eggert1-3/+4
PATH_MAX is standardized, MAXPATHLEN is not. Also, the Gnulib pathmax module fixes some rare bugs with PATH_MAX. So prefer PATH_MAX to MAXPATHLEN unless we know the latter is also correct (for some platform-specific code). * admin/merge-gnulib (GNULIB_MODULES): Add pathmax. This module was already present, as a dependency of canonicalize-lgpl, but now Emacs is using it directly. Sort. * lib-src/emacsclient.c: Include stdint.h, pathmax.h. (get_current_dir_name): Sync to current src/sysdep.c. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * src/sysdep.c: Include pathmax.h. (get_current_dir_name_or_unreachable): Use PATH_MAX instead of MAXPATHLEN.
2019-06-25Avoid some strlen work, primarily via strnlenPaul Eggert1-2/+2
* admin/merge-gnulib (GNULIB_MODULES): Add strnlen. * lib-src/etags.c (find_entries): * src/emacs.c (main): * src/nsmenu.m (parseKeyEquiv:): * src/nsterm.m (ns_xlfd_to_fontname): * src/term.c (vfatal): Prefer !*X to !strlen (X). * lib-src/etags.c (pfnote, add_regex): * lib-src/pop.c (pop_open): * lib-src/update-game-score.c (main): * lwlib/lwlib.c (lw_separator_p): * src/doprnt.c (doprnt): * src/emacs.c (main): * src/inotify.c (inotifyevent_to_event): * src/keyboard.c (menu_separator_name_p, parse_tool_bar_item): * src/sysdep.c (get_current_dir_name_or_unreachable): * src/xdisp.c (store_mode_line_string): Use strnlen to avoid unnecessary work with strlen. * lib-src/etags.c (Prolog_functions, prolog_pr) (Erlang_functions, erlang_func): Prefer ptrdiff_t to size_t when either will do. (prolog_pr, erlang_func): New arg LASTLEN, to avoid unnecessary strlen call. 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.
2019-06-23Don’t line-buffer stderrPaul Eggert1-6/+0
* src/sysdep.c (init_standard_fds) [DOS_NT]: Don’t line-buffer stderr. This reverts 2019-06-20T07:32:17!eggert@cs.ucla.edu. See: https://lists.gnu.org/r/emacs-devel/2019-06/msg00882.html
2019-06-20Check that length of data returned by sysctl is non-zeroRobert Pluim1-5/+5
The length of the data returned by sysctl can be zero, which was not checked for. This could cause crashes, e.g. when querying non-existent processes. (Bug#36279) * src/sysdep.c (list_system_processes) [DARWIN_OS || __FreeBSD__]: (system_process_attributes) [__FreeBSD__]: (system_process_attributes) [DARWIN_OS]: * src/filelock.c (get_boot_time) [CTL_KERN && KERN_BOOTTIME]: Check for zero length data returned by sysctl.
2019-06-20Simplify stdout bufferingPaul Eggert1-18/+1
* src/sysdep.c (_sobuf): Remove; we no longer need this microoptimization. (init_sys_modes): Simplify by assuming setvbuf.
2019-06-20Line-buffer stderrPaul Eggert1-0/+6
* src/sysdep.c (init_standard_fds) [!DOS_NT]: Use setvbuf to ensure stderr is line-buffered.
2019-04-18Mark _Noreturn error functions as coldPaul Eggert1-1/+1
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. (ATTRIBUTE_COLD): New macro. * src/frame.h (WINDOW_SYSTEM_RETURN): Add ATTRIBUTE_COLD. * src/lisp.h (AVOID): New macro. * src/xterm.c: Omit unnecessary static decls, so that we needn’t worry about which functions should be marked cold. (x_io_error_quitter): Mark as cold.
2019-03-21Fix misuses of NULL when talking about the NUL characterStefan Monnier1-3/+3
* lisp/subr.el (inhibit-null-byte-detection): Make it an obsolete alias. * src/coding.c (setup_coding_system): Use new name. (detect_coding): Rename null_byte_found => nul_byte_found. (detect_coding_system): Use new name. Rename null_byte_found => nul_byte_found. (Fdefine_coding_system_internal): Use new name. (syms_of_coding): Rename inhibit-null-byte-detection to inhibit-nul-byte-detection. * src/w16select.c (get_clipboard_data): null_char => nul_char. * src/json.c (check_string_without_embedded_nuls): Rename from check_string_without_embedded_nulls. (Fjson_parse_string): Adjust accordingly. * src/coding.h (enum define_coding_undecided_arg_index) (enum coding_attr_index): ...null_byte... => ...nul_byte.... * lisp/info.el (info-insert-file-contents, Info-insert-dir): * lisp/international/mule.el (define-coding-system): * lisp/vc/vc-git.el (vc-git--call): * doc/lispref/nonascii.texi (Lisp and Coding Systems): Use the new name.
2019-03-19Use ‘const’ to clarify GC markingPaul Eggert1-2/+2
Add ‘const’ to make the GC marking code a bit clearer. This can also help the compiler in some cases, I think because GCC can now determine more often that the value of a static C variable can be cached when its address is now converted to ‘Lisp Object const *’ before escaping. * src/alloc.c (staticvec, mark_maybe_objects, mark_memory) (mark_stack, staticpro, mark_object_root_visitor) (garbage_collect_1): * src/pdumper.c (dump_ptr_referrer, dump_emacs_reloc_to_lv) (dump_emacs_reloc_to_emacs_ptr_raw, dump_root_visitor): * src/lisp.h (vcopy, struct gc_root_visitor): * src/sysdep.c (stack_overflow): * src/thread.c (mark_one_thread): * src/thread.h (struct thread_state): Use pointer-to-const instead of plain pointer in some GC-related places where either will do.
2019-01-31Prefer static to extern where either will doPaul Eggert1-2/+2
* src/charset.c (charset_table_size): * src/pdumper.c (dump_private): * src/sysdep.c (init_sigsegv): * src/window.c (old_selected_window): Now static. * src/charset.c (charset_table_size): Now int, since the value always fits in int. * src/gtkutil.c (xg_gtk_initialized): Now present only if HAVE_XWIDGETS, to make it clearer that this is an xwidgets hack. All uses changed. * src/lread.c (ndefsubr): Remove; unused. * src/pdumper.h: Use usual GNU indenting style for functions, since my static-vs-extern checking hack relies on it. (dump_public): Always declare; simpler and doesn’t hurt. (pdumper_handle_page_fault): Remove unused decl.
2019-01-15Add portable dumperDaniel Colascione1-6/+9
Add a new portable dumper as an alternative to unexec. Use it by default. * src/dmpstruct.awk: New file. * src/doc.c (get_doc_string): use will_dump_p(). * src/editfns.c (styled_format): silence compiler warning with UNINIT. * src/emacs-module.c (syms_of_module): staticpro ltv_mark. * src/emacs.c (gflags): new variable. (init_cmdargs): unwrap (string_starts_with_p, find_argument, dump_error_to_string) (load_pdump): new functions. (main): detect pdumper and --temacs invocation; actually load portable dump when detected; set gflags as appropriate; changes to init functions throughout to avoid passing explicit 'initialized' argument. * src/eval.c (inhibit_lisp_code): remove unused variable. (init_eval_once_for_pdumper): new function. (init_eval_once): call it. * src/filelock.c: CANNOT_DUMP -> will_dump_p() * src/fingerprint-dummy.c: new file * src/fingerprint.h: new file * src/fns.c: CANNOT_DUMP -> will_dump_p(), etc. (weak_hash_tables): remove (hashfn_equal, hashfn_eql): un-staticify (make_hash_table): set new 'next_weak' hash table field; drop global weak_hash_tables logic. (copy_hash_table): drop global weak_hash_tables logic. (hash_table_rehash): new function. (hash_lookup, hash_put, hash_remove_from_table, hash_clear): rehash if needed. (sweep_weak_table): un-staticify; explain logic; bool-ify. (sweep_weak_hash_tables): remove function. * src/font.c (syms_of_font): remember pdumper stuff. * src/fontset.c (syms_of_fontset): remember pdumper stuff. * src/frame.c (make_initial_frame): don't reset Vframe_list. (init_frame_once_for_pdumper, init_frame_once): new functions. (syms_of_frame): remove redundant staticpro. * src/fringe.c (init_fringe_once_for_pdumper): new functin.

2018-08-27Improve bignum support for system typesPaul Eggert1-55/+47
Use bignums when Emacs converts to and from system types like off_t for file sizes whose values can exceed fixnum range.

* src/sysdep.c (list_system_processes): * src/xfaces.c (Finternal_set_lisp_face_attribute_from_resource): Defend against Fstring_to_number returning a float or a nonsense integer.
2018-02-20Port recent MAX_RW_COUNT checks to POSIXPaul Eggert1-10/+19
* src/sysdep.c (MAX_RW_COUNT): Verify that it fits in POSIX standard types, to go along with already-existing checks for MS-Windows types. (emacs_intr_read): eassert on all platforms, not just MS-Windows.
2018-02-20Add assertion to guard 'read' calls on MS-WindowsEli Zaretskii1-0/+8
* src/sysdep.c (emacs_intr_read): Assert that NBYTES never overflows a 32-bit int.
2018-01-01Update copyright year to 2018Paul Eggert1-1/+1
Run admin/update-copyright.
2017-12-24Make main_thread_id privatePaul Eggert1-1/+1
* src/sysdep.c (main_thread_id) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Now static.
2017-11-25maint: shorten https://lists.gnu.org/archive/html/... linksPaul Eggert1-2/+2
2017-10-18Fix the MSDOS build.Eli Zaretskii1-1/+2
* msdos/sed1v2.inp (GETADDRINFO_A_LIBS, LIBLCMS2, XDBE_LIBS) (XDBE_FLAGS, HYBRID_MALLOC, LIBSYSTEMD_CFLAGS) (LIBSYSTEMD_LIBS): Edit to empty. (LIBRESOLV, DEPFLAGS, MKDEPDIR, YMF_PASS_LDFLAGS) (PRE_EDIT_LDFLAGS, POST_EDIT_LDFLAGS): Remove editing. Remove editing of lines that are no longer present in src/Makefile.in. * msdos/sed2v2.inp (NEED_MKTIME_INTERNAL) (NEED_MKTIME_WORKING): Define to 1. (HAVE_STRUCT_DIRENT_D_TYPE): Define to 1 for DJGPP >= 2.05. (HAVE_STRUCT_ATTRIBUTE_ALIGNED): Define to 1. Define PACKAGE_VERSION, not VERSION. (FLEXIBLE_ARRAY_MEMBER): Define to empty. (HAVE_DECL_*_UNLOCKED): Define to 0. (HAVE___BUILTIN_FRAME_ADDRESS): Define to 1. (PENDING_*): Don't define, as Gnulib no longer supports that. Instead, define _IOERR as it is in libc/file.h. * msdos/sed3v2.inp: Use $(CURDIR) instead of $(shell cd) to determine the current directory. (UPDATE_MANIFEST, UTILITIES): Don't edit. * msdos/sedlisp.inp (FIND_DELETE): Edit to "-delete". * msdos/sedlibmk.inp (AUTO_DEPEND): Define to yes. (HYBRID_MALLOC): Edit to empty. (am__cd): Don't edit. (../config.status): Replaces $(top_builddir)/config.status. Define OMIT_GNULIB_MODULE_foo = true for modules not built for MS-DOS. Convert GL_GENERATE_xxx_H_TRUE and GL_GENERATE_xxx_H_FALSE into values of GL_GENERATE_xxx_H. * msdos/mainmake.v2 (src): Use 'compile-one-process', and make the command line shorter to fit into 126-char limit of command.com. * config.bat: Generate src/deps/*.d files. Rename more files like djtar on plain DOS would. Don't rename src/dir.h: it is long gone. Edit lib/gnulib.mk.in using the same scripts as for lib/Makefile.in. * msdos/depfiles.bat: Create *.d files, not *.Po. * src/thread.c (Fmake_thread) [!THREADS_ENABLED]: Improve the error message. * src/thread.h [MSDOS]: Include <signal.h>. * src/sysselect.h (select) [MSDOS]: Undefine, to avoid compilation errors. * src/sysdep.c (block_interrupt_signal, restore_signal_mask): Expose to MSDOS build. * src/process.c (update_processes_for_thread_death) [!subprocess]: No-op implementation. [HAVE_SETRLIMIT]: Move inclusion of sys/resource.h and declaration of nofile_limit outside "#ifdef subprocesses", as it's needed for MSDOS. * src/msdos.c (faccessat): Declare fullname[]. * src/msdos.h (ENOTSUP): Define to be identical to ENOSYS. Include termhooks.h. * src/conf_post.h [WINDOWSNT]: Include ms-w32.h only on WINDOWSNT, not DOS_NT. * admin/admin.el (set-version): Set version on PACKAGE_VERSION.
2017-10-09Fix PWD check on DOS_NTPaul Eggert1-1/+1
* src/sysdep.c (get_current_dir_name_or_unreachable): Do not consider a file name like "a:b" to be absolute on DOS_NT.
2017-10-09Fix unlikely overflows with wd lengthPaul Eggert1-18/+39
* src/sysdep.c (get_current_dir_name_or_unreachable): Avoid integer overflow if working directory name is absurdly long. When allocating memory for getcwd, do not exceed MAXPATHLEN.
