* | | Revert O_PATH change to fileio.cPaul Eggert2019-06-281-4/+0
| | | | | | | | | | | | | | | Ken Brown pointed out it wasn’t needed (Bug#36405#16): * src/fileio.c (O_PATH) [__CYGWIN__]: Remove #undef.
* | | Correct regexp matching of raw bytesMattias Engdegård2019-06-281-4/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make regexp matching of raw bytes work in all combination of unibyte and multibyte patterns and targets, as exact strings and in character alternatives (bug#3687). * src/regex-emacs.c (analyze_first): Include raw byte in fastmap when pattern is a multibyte exact string. Include leading byte in fastmap for raw bytes in character alternatives. (re_match_2_internal): Decrement the byte count by the number of bytes in the pattern character, not 1. * test/src/regex-emacs-tests.el (regexp-unibyte-unibyte) (regexp-multibyte-unibyte, regexp-unibyte-mutibyte) (regexp-multibyte-multibyte): New tests.
* | | More readable regexp debug outputMattias Engdegård2019-06-281-10/+22
| | | | | | | | | | | | | | | | | | | | | * src/regex-emacs.c (debug_putchar): New. (print_fastmap, print_partial_compiled_pattern, print_double_string) (regex_compile): Use debug_putchar. (re_match_2_internal): Add newline.
* | | Consistently use stderr for debug output in regexp codeMattias Engdegård2019-06-281-17/+18
| | | | | | | | | | | | | | | * src/regex-emacs.c (DEBUG_PRINT, print_fastmap, print_compiled_pattern) (print_double_string, regex_compile): Print to stderr instead of stdout.
* | | * src/xfaces.c (resolve_face_name): Simplify.Paul Eggert2019-06-271-1/+1

* | | Remove unnecessary tortoise checks.Pip Cet2019-06-272-11/+0
| | | | | | | | | | | | | | | | | | * src/fns.c (Fplist_get, Fplist_put, Flax_plist_get) (Flax_plist_put, Fplist_member): Remove unnecessary check. * src/json.c (lisp_to_json_toplevel_1): Remove unnecessary check.
* | | Work around Cygwin bug with O_PATHPaul Eggert2019-06-272-0/+8
| | | | | | | | | | | | | | | Problem reported by Ken Brown (Bug#36405). * src/dired.c, src/fileio.c (O_PATH) [__CYGWIN__]: Undef.
* | | Omit a few minor unnecessary range checksPaul Eggert2019-06-273-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on Pip Cet’s review (Bug#36370#19). * src/fileio.c (Fdo_auto_save): * src/image.c (lookup_image): * src/textprop.c (Fnext_single_char_property_change): Prefer XFIXNUM to XFIXNAT for clarity and consistency with neighboring code, and to avoid unnecessary range checks. * src/image.c (lookup_image): Omit unnecessary range checks.
* | | Improve XFIXNUM cleanup a bitPaul Eggert2019-06-273-17/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on Pip Cet’s review (Bug#36370#13). * src/ccl.c (Fccl_execute_on_string): Use clearer indexing. * src/dosfns.c (Fint86, Fdos_memput): Avoid runtime checks for negative fixnums when debugging. This restores the earlier machine code. * src/lisp.h (XFIXNUM, XUFIXNUM): Use eassert, not eassume. (XFIXNAT): At the start, merely eassert FIXNUMP rather than eassuming FIXNATP. At the end, eassume that the result is nonnegative. This restores help to the compiler that the previous patch mistakenly removed.
* | | Clean up use of XFIXNUM etc.Paul Eggert2019-06-2710-65/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A few bits of the code were relying on the fact that XFIXNUM, XFIXNAT, and XUFIXNUM do something even with arguments that are not fixnums/fixnats. Separate these rare uses out into XFIXNUM_RAW and XUFIXNUM_RAW. Problem and original patch reported by Pip Cet (Bug#36370). * src/ccl.c (Fccl_execute_on_string): * src/fileio.c (Finsert_file_contents, a_write) (Fdo_auto_save): * src/process.c (conv_lisp_to_sockaddr): * src/textprop.c (Fnext_single_char_property_change) (Fprevious_single_char_property_change) (Fnext_property_change, Fnext_single_property_change) (Fprevious_property_change) (Fprevious_single_property_change): Don’t assume fixnums are nonnegative. * src/ccl.c (Fccl_execute_on_string): Fix range-checking bug if AREF (status, i) is out of int range. * src/data.c (arith_driver): Use XFIXNUM_RAW as we want efficient garbage if the value is not a fixnum. * src/dosfns.c (Fint86, Fdos_memput): Check that args are nonnegative. * src/image.c (lookup_image): Check that args are in range. * src/lisp.h (lisp_h_XHASH): Use XUFIXNUM_RAW, since this is for hashing. (lisp_h_XFIXNAT, XFIXNAT) [USE_LSB_TAG]: Remove macros. (lisp_h_XFIXNUM_RAW, XFIXNUM_RAW) [USE_LSB_TAG]: New macros, with the semantics of the old macros without _RAW. (XFIXNUM_RAW, XUFIXNUM_RAW): New inline functions, with the semantics of the old functions without _RAW. (FIXNUMP): Move definition up to avoid forward use. (XFIXNUM, XFIXNAT, XUFIXNUM): Use eassume to add a runtime check (when debugging) that the argument has the proper form. (XFIXNUM, XFIXNAT): Now inline functions only, since they refer to their arguments more than once now that they use eassume. * src/textprop.c (Fprevious_single_char_property_change): Avoid fixnum overflow with invalid input. (set_text_properties): Fix unlikely failure to validate arguments, by using EQ instead of XFIXNAT. * src/w32term.c (w32_draw_glyph_string): * src/xterm.c (x_draw_glyph_string): Treat negative minimums as 0 rather than as garbage patterns.
* | | Catch duplicate keywords in image specsPaul Eggert2019-06-271-23/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | * src/image.c (struct image_keyword.count): Now bool, not int, since it is either 0 or 1. (parse_image_spec, xpm_image_p): Use bool for boolean. (parse_image_spec): Fix a bug introduced in 2011-09-21T17:41:20!eggert@cs.ucla.edu that reported only triplicate (or more) keywords, not duplicates.
* | | Fix invoking Emacs via a symlink on CygwinKen Brown2019-06-271-1/+1
| | | | | | | | | | | | * src/emacs.c (load_pdump) [CYGWIN]: Strip ".exe" suffix.
* | | Support invoking Emacs via a symlink on MS-WindowsEli Zaretskii2019-06-262-4/+22
| | | | | | | | | | | | | | | | | | | | | | | | * src/w32.c (w32_my_exename): Resolve symlinks in the executable name, to support searching for the pdumper file when the executable is found via a symlink. * src/emacs.c (load_pdump): Add a comment about symlink resolution on Windows.
* | | Restrict indirect lookups in Fdocumentation_propertyLars Ingebrigtsen2019-06-261-3/+5
| | | | | | | | | | | | | | | * src/doc.c (Fdocumentation_property): Only look up indirect variables if we've been asked for the variable documentation.
* | | Fdocumentation_property: Return doc string for indirect variablesLars Ingebrigtsen2019-06-261-0/+12
| | | | | | | | | | | | | | | | | | * src/doc.c (Fdocumentation_property): When dealing with indirect variables (i.e., aliases), also check the symbol being pointed to for the doc string (bug #17180).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | Prefer PATH_MAX to MAXPATHLENPaul Eggert2019-06-251-3/+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.
* | | Avoid some strlen work, primarily via strnlenPaul Eggert2019-06-2511-29/+21

(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.
* | | Make message_to_stderr do one single fwriteLars Ingebrigtsen2019-06-251-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/xdisp.c (message_to_stderr): When running as a batch process, the output from `message' goes to stderr, and has a newline appended. Rewrite the code so that only one fwrite is performed to enable messages that are shorter than PIPE_BUF (usually 4096 on modern operating systems) are written out as one chunk, as this will ensure that the messages are not interleaved with messages from other processes that are writing at the same time. This does not affect other stderr outputs, just the ones from `message'.
