* Make garbage collection more conservativePaul Eggert2017-08-291-132/+193
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Check for a pointer anywhere within the object, as opposed to just the start of the object. This is needed for gcc -Os -flto on x86-64 (Bug#28213). This change means that the garbage collector is more conservative, and will incorrectly keep objects that it does not need to, but that is better than incorrectly discarding objects that should be kept. * src/alloc.c (ADVANCE, VINDEX): Now functions, not macros; this is easier to debug. (setup_on_free_list): Rename from SETUP_ON_FREE_LIST. Now a function with two args, not a macro with three. All callers changed. (live_string_holding, live_cons_holding, live_symbol_holding) (live_misc_holding, live_vector_holding, live_buffer_holding): New functions, which check for any object containing the addressed byte, not just for an object at the given address. (live_string_p, live_cons_p, live_symbol_p, live_misc_p) (live_vector_p, live_buffer_p): Redefine in terms of the new functions. (live_float_p): Refactor slightly to match the new functions. (mark_maybe_object, mark_maybe_pointer): Use the new functions. Don’t bother checking mark bits, as mark_object already does that, and omitting the checks here simplifies the code. Although mark_maybe_object can continue to insist that tagged pointers still address the start of the object, mark_maybe_pointer now is more conservative and checks for pointers anywhere into an object.
* Improve stack-top heuristicPaul Eggert2017-08-293-7/+31
| | | | | | | | | | | | | | This is needed for gcc -Os -flto on x86-64; otherwise, GC misses part of the stack when scanning for heap roots, causing Emacs to crash later (Bug#28213). The problem is that Emacs's hack for getting an address near the stack top does not work when link-time optimization moves stack variables around. * configure.ac (HAVE___BUILTIN_FRAME_ADDRESS): New macro. * lib-src/make-docfile.c (DEFUN_noinline): New constant. (write_globals, scan_c_stream): Support noinline. * src/alloc.c (NEAR_STACK_TOP): New macro. (SET_STACK_TOP_ADDRESS): Use it. (flush_stack_call_func, Fgarbage_collect): Now noinline.
* Align stack bottom properly.Paul Eggert2017-08-291-2/+5
| | | | | | This is needed for gcc -Os -flto on x86-64 (Bug#28213). * src/emacs.c (main): Align stack-bottom variable as a pointer, since mark_memory requires this.

* Disable completion while entering python multiline statementsNoam Postavsky2017-08-271-1/+15
| | | | | | | | | | | The "legacy" completion mechanism sends newlines to the running python process to get the list of completions, which confuses things if the user is in the middle of entering a multiline statement (Bug#28051). It's better to disable completion in this case. * lisp/progmodes/python.el (python-shell--block-prompt): New variable. (python-shell-prompt-set-calculated-regexps): Set it. (python-shell-completion-at-point): Return 'ignore' as the completion function when the current prompt is a block prompt.

* Fix over-protection of byte-compiled filesPaul Eggert2017-08-262-1/+12

Also, fix similar problem for autoload files. * lisp/emacs-lisp/autoload.el (autoload--save-buffer): Set temp file modes to the buffer-file-name file modes (or 666 if not available) as adjusted by umask. * lisp/emacs-lisp/bytecomp.el (byte-compile-file): Set temp file modes to 666 as adjusted by umask.
* Refine conf-toml-mode font-lockTom Tromey2017-08-261-2/+28
| | | | | | | Bug#28218 * lisp/textmodes/conf-mode.el (conf-toml-font-lock-keywords): Use conf-toml-recognize-section. Use \s- in variable regexp. (conf-toml-recognize-section): New function.
* Do not munge contents of local symbolic linksPaul Eggert2017-08-267-50/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | This lets Emacs deal with arbitrary local symlinks without mishandling their contents (Bug#28156). For example, (progn (shell-command "ln -fs '~' 'x'") (rename-file "x" "/tmp/x")) now consistently creates a symbolic link from '/tmp/x' to '~'. Formerly, it did that only if the working directory was on the same filesystem as /tmp; otherwise, it expanded the '~' to the user's home directory. * lisp/dired.el (dired-get-filename): Use files--name-absolute-system-p instead of rolling our own code. * lisp/files.el (files--name-absolute-system-p): New function. (file-truename, file-chase-links): Use it to avoid mishandling symlink contents that begin with ~. (copy-directory, move-file-to-trash): Use concat rather than expand-file-name, to avoid mishandling symlink contents that begin with ~. * src/fileio.c (Fmake_symbolic_link): Do not expand leading "~" in the target unless interactive. Strip leading "/:" if interactive. (emacs_readlinkat): Do not prepend "/:" to the link target if it starts with "/" and contains ":" before NUL. * test/src/fileio-tests.el (try-link): Rename from try-char, and accept a string instead of a char. All uses changed. (fileio-tests--symlink-failure): Also test leading ~, and "/:", to test the new behavior.
* Remove invalid regexp for shell builtins for wkshReuben Thomas2017-08-271-3/+1
| | | | | | * lisp/progmodes/sh-script.el (sh-builtins): Shell built-ins have to be literal strings, so remove a regexp for wksh. In any case, it’s a defunct proprietary shell.

| | | | | | | | | | | | | | | | * lisp/files.el (file-name-non-special): Use `file-name-quote' instead prefixing "/:", the file could already be quoted. * lisp/net/tramp.el (tramp-error): Handle null arguments. (tramp-handle-make-symbolic-link): * lisp/net/tramp-sh.el (tramp-sh-handle-make-symbolic-link) (tramp-sh-handle-add-name-to-file): * lisp/net/tramp-smb.el (tramp-smb-handle-add-name-to-file) (tramp-smb-handle-make-symbolic-link): Adapt implementation to stronger semantics in Emacs.

| | | | | | | | * lisp/man.el (Man-see-also-regexp): Add support for SEE ALSO section detection in several langages: French, German, Spanish, Portugese, Italian, Polish, Turkish, Japanese, Chinese. (Bug#28142) Copyright-paperwork-exempt: yes
* Improve expand-file-name docPaul Eggert2017-08-253-23/+26
| | | | | | | | | | | * doc/lispref/files.texi (Relative File Names, Directory Names) (File Name Expansion): * doc/lispref/minibuf.texi (Reading File Names): Document expand-file-name behavior with ~ more clearly and accurately. * doc/misc/org.texi (Batch execution): Simplify example script so that it does not need expand-file-name and thus will not mishandle file names with leading ~.
* Support all perl variable declarators and prefixes (Bug#27613)Jefferson Carpenter2017-08-251-3/+4
| | | | | | | | * lisp/progmodes/perl-mode.el (perl-imenu-generic-expression) (perl-font-lock-keywords-2): Match declators 'anon', 'argument', 'has', 'local', 'state', 'supersede', 'let', and 'temp'. Copyright-paperwork-exempt: yes

| | | | | | | | | | | | | * doc/lispref/files.texi (File Attributes): Document file-attributes atomicity. * etc/NEWS: Document the fix. * src/dired.c (file_attributes): New args DIRNAME and FILENAME, for diagnostics. All callers changed. On platforms like GNU/Linux that support O_PATH, fix a race condition in file-attributes and similar functions, so that these functions do not return nonsense if a directory entry is replaced while getting its attributes. On non-GNU platforms, do a better (though not perfect) job of detecting the race, and return nil if detected.
* Simplify expand_and_dir_to_filePaul Eggert2017-08-253-59/+30
| | | | | | * src/fileio.c (expand_and_dir_to_file): Simplify by omitting 2nd argument, since in practice it always has the default value. All callers changed. Prefer C99 style decls in nearby code.
