* Refactor common code in {upcase,downcase,capitalize}-word functionsMichal Nazarewicz2016-09-121-27/+17
| | | | | | | | | * src/casefiddle.c (operate_on_word): Removed in favour of… (casify_word) …new function which does what operate_on_word did plus what all of the common code from *-word functions. (upcase-word, downcase-word, capitalize-word): Move code common between those functions (pretty much the whole body of those functions) into casify_word and use that instead of now deleted operate_on_word.
* copy-file now uses GNU/Linux file cloningPaul Eggert2016-09-101-8/+25
| | | | | | | | From a suggestion by Kieran Colford (see Bug#23904). * configure.ac: Check for linux/fs.h. * src/fileio.c [HAVE_LINUX_FS_H]: Include sys/ioctl.h and linux/fs.h. (clone_file): New function. (Fcopy_file): Use it.
* Invert y coord of NS image files (bug#7847)Alan Third2016-09-101-1/+2
| | | | | * src/nsterm.m (ns_dumpglyphs_image): Invert y co-ordinate of the image when compositing.
* Remove dead loop iterations in regex.cMichal Nazarewicz2016-09-091-16/+12
| | | | | | | | | | | | | | | | | | | | | | | | | RE_CHAR_TO_MULTIBYTE(c) yields c for ASCII characters and a byte8 character for c ≥ 0x80. Furthermore, CHAR_BYTE8_P(c) is true only for byte8 characters. This means that c = RE_CHAR_TO_MULTIBYTE (ch); if (! CHAR_BYTE8_P (c) && re_iswctype (c, cc)) is equivalent to: c = c; if (! false && re_iswctype (c, cc)) for 0 ⪬ c < 0x80, and c = BYTE8_TO_CHAR (c); if (! true && re_iswctype (c, cc)) for 0x80 ⪬ c < 0x100. In other words, the loop never executes for c ≥ 0x80 and RE_CHAR_TO_MULTIBYTE call is unnecessary for c < 0x80. * src/regex.c (regex_compile): Simplyfy a for loop by eliminating dead iterations and unnecessary macro calls.
* Replace decimalnump with alphanumericpMichal Nazarewicz2016-09-093-6/+15
| | | | | | | | | | | | | decimalnump was used in regex.c only in ISALNUM macro which ored it with alphabeticp. Because both of those functions require Unicode general category lookup, this resulted in unnecessary lookups (if alphabeticp return false decimalp had to perform another lookup). Drop decimalnump in favour of alphanumericp which combines decimelnump with alphabeticp. * src/character.c (decimalnump): Remove in favour of… (alphanumericp): …new function. * src/regex.c (ISALNUM): Use alphanumericp.
* Remove inaccurate comment in regex.cMichal Nazarewicz2016-09-091-2/+1
| | | | | | * src/regex.c (regex_compile): Remove comment indicating that wctype of some character classes may be negative. All wctypes are in fact non-negative.
* STRING_CHAR does not unify characters; update documentationMichal Nazarewicz2016-09-092-17/+3
| | | | | | * src/character.h (STRING_CHAR): Update doc. * src/buffer.h (FETCH_MULTIBYTE_CHAR): Update doc. While at it, change the function to use BYTE_POS_ADDR instead of open-coding it.
* Port flexible array members to GCC + valgrindPaul Eggert2016-09-074-27/+20
| | | | | | | | | | | | | | | | | | | | | | | | | These changes are needed to conform to the C standard's rule for allocating structs containing flexible array members. C11 says that malloc (offsetof (struct s, m) + n) does not suffice to allocate a struct with an n-byte tail; instead, malloc’s arg should be rounded up to the nearest multiple of alignof (struct s). Although this is arguably a defect in C11, gcc -O2 + valgrind sometimes complains when this rule is violated, and when debugging it’s better to keep valgrind happy. For details please see the thread containing the message at: https://gcc.gnu.org/ml/gcc-patches/2016-09/msg00416.html * lib-src/ebrowse.c, src/alloc.c, src/image.c, src/process.c: Include flexmember.h. * lib-src/ebrowse.c (add_sym, add_member, make_namespace) (register_namespace_alias): * src/alloc.c (SDATA_SIZE, allocate_string_data): * src/image.c (xpm_cache_color, imagemagick_create_cache): * src/process.c (Fmake_network_process): Use FLEXSIZEOF instead of offsetof and addition. * src/alloc.c (SDATA_SIZE, vector_alignment): Use FLEXALIGNOF instead of sizeof (ptrdiff_t). * src/lisp.h (ALIGNOF_STRUCT_LISP_VECTOR): Remove, as alloc.c can now calculate this on its own.
* Use DEV_TTY more consistentlyPaul Eggert2016-09-065-13/+12
| | | | | | | | * src/conf_post.h (DEV_TTY): Move from here ... * src/keyboard.c, src/keyboard.h: ... to here, as it doesn’t need to be visible everywhere. Make it a constant. * src/keyboard.c (handle_interrupt, Fset_quit_char): * src/process.c (create_process): Prefer DEV_TTY to "/dev/tty".
* Avoid assertion violations when using marker positionsEli Zaretskii2016-09-062-5/+14
| | | | | | | | | * src/intervals.c (set_point_from_marker): If MARKER comes from another buffer, recalculate its byte position before using it to set point. * src/marker.c (set_marker_internal): If POSITION is a marker from another buffer, recalculate its byte position before using it. (Bug#24368)
* Avoid assertion violations when scrolling narrowed bufferEli Zaretskii2016-09-052-4/+6
| | | | | | | | * src/window.c (window_scroll_pixel_based): * src/xdisp.c (pos_visible_p): Don't allow simulated redisplay to start outside the accessible portion of the buffer. This avoids assertion violations when some Lisp narrows the buffer to less than the current window, and then attempts to scroll the buffer.
* Treat SIGINT correctly in GUI sessions on MS-WindowsEli Zaretskii2016-09-054-6/+12
| | | | | | | | | | | | * src/w32proc.c (sys_signal): Don't reject SIGINT, as it is supported by MS runtime. * src/term.c (DEV_TTY): Move from here ... * src/conf_post.h (DEV_TTY): ... to here. Separate definitions for WINDOWSNT and for the rest. * src/keyboard.c (handle_interrupt_signal): Use DEV_TTY instead of a literal "/dev/tty". * etc/NEWS: Mention the behavior change.
* Fix synthetic bold on macOS retina displaysAlan Third2016-09-041-0/+12
| | | | | * src/macfont.m (macfont_draw): Multiply the synthetic bold scaling factor by the OS window backing scale factor.
* Check actual contents before promting about changed fileStefan Monnier2016-09-021-1/+1
| | | | | | | | * lisp/userlock.el (userlock--check-content-unchanged) (userlock--ask-user-about-supersession-threat): New functions. * src/filelock.c (lock_file): Use them to avoid spurious prompting. * doc/lispref/buffers.texi (Modification Time): Update doc of ask-user-about-supersession-threat.
* Don’t create fd >= FD_SETSIZEPaul Eggert2016-09-011-0/+14
| | | | | | | This avoids a potential crash if too many subprocesses (Bug#24325). * src/process.c [HAVE_SETRLIMIT]: Include <sys/resource.h>. (init_process_emacs): If ulimit -n is greater than FD_SETSIZE, set it to FD_SETSIZE.
* Fix over-substitution of quotes on errorPaul Eggert2016-08-311-2/+2
| | | | | | | Problem reported by Tino Calancha in: http://lists.gnu.org/archive/html/emacs-devel/2016-09/msg00000.html * src/print.c (print_error_message): Substitute quotes in errmsg only when gotten from a property.
* * src/editfns.c (Fformat_message): Fix doc to match current behavior.Paul Eggert2016-08-301-4/+3

* Minor doc quoting fixesPaul Eggert2016-08-302-3/+3
| | | | | | | | | | | | * doc/misc/htmlfontify.texi (Interactive): * lisp/htmlfontify.el (htmlfontify-buffer): Spell out character names, for clarity. The old doc string generated the *Help* text ‘^L ([FF]) or ¤ (244)’, where ‘[FF]’ stands for a form feed character; this was confusing. * lisp/electric.el (electric-quote-mode): * src/doc.c (syms_of_doc): * src/editfns.c (Fformat_message): Remove no-longer-necessary ‘\=’s in doc strings.
* Clarify docstringsAlan Third2016-08-291-7/+14
| | | | * src/nsterm.m: Clarified that ns-x-modifier variables require a symbol.
* Avoid crashes for invalid value of key modifiersEli Zaretskii2016-08-291-1/+6
| | | | | | | | | | * src/keyboard.c (parse_solitary_modifier): If the argument SYMBOL is not a symbol, don't try to recognize it. See http://lists.gnu.org/archive/html/emacs-devel/2016-08/msg00502.html for the details. * test/src/keymap-tests.el (keymap-where-is-internal-test): New test, for testing the above fix.
* Memory allocator alignment fixesPaul Eggert2016-08-281-33/+48
| | | | | | | | | | | | | | | | | | | | | | | | | These changes remove some assumptions about heap allocator alignment that may not be true on unusual platforms. * src/alloc.c (POWER_OF_2): New macro. (ROUNDUP): Use it. (BLOCK_ALIGN): Verify that it is a power of 2. (aligned_alloc): Check that alignment passed to posix_memalign satisfies POSIX restrictions. (lisp_align_malloc): Check that size passed to aligned_alloc satisfies C11 restrictions. (MALLOC_IS_GC_ALIGNED): Check that GCALIGNMENT is 8, since the code has not been verified to work with other GCALIGNMENT values and the ice is thin here. On GNU/Linux, malloc can return a value that is a multiple of 8 but not 16, even though __alignof__ (max_align_t) is 16. See: https://gcc.gnu.org/ml/gcc-patches/2016-08/msg01902.html (lmalloc) [USE_ALIGNED_ALLOC]: Use aligned_alloc only if size is a multiple of alignment, since C11 says the behavior is undefined otherwise. (lmalloc, lrealloc): Don't use INT_ADD_WRAPV on size_t, as in general this macro is restricted to signed types. Remove assertion that the result is a multiple of GCALIGNMENT, as that need not be true.
* Some fixes around `delete-other-frames' and `next-frame'Martin Rudalics2016-08-251-1/+1
| | | | | | | | | | | | * src/frame.c (Fdelete_frame): Clarify doc-string. * lisp/frame.el (delete-other-frames): Delete other frames on FRAME's terminal instead of the current terminal. Delete non-minibuffer-only surrogate frames too. See http://lists.gnu.org/archive/html/emacs-devel/2016-08/msg00467.html * doc/lispref/frames.texi (Deleting Frames): Minor fixes for docs of `delete-frame' and `frame-live-p'. Add entry for `delete-other-frames'. (Finding All Frames): Fix doc of `next-frame'.
* Fix macOS 12 deprecation noticesAlan Third2016-08-244-88/+127
| | | | | | | | | | | * src/nsterm.h: Add #defines to allow older versions of macOS to use the new constant names. * src/nsmenu.m: Replace old constant names with new. (fillWithWidgetValue): Remove calls to deprecated setMenuChangedMessagesEnabled. * src/nsterm.m: Replace old constant names with new. * src/nsfns.m: Replace old constant names with new.
* * src/xfns.c (Fx_change_window_property): Modify previous change.Noah Friedman2016-08-231-5/+27
| | | | | | | Instead of forcing format to 8 for strings, check that the length of the string is appropriate for whatever format given. (Fx_window_property_attributes): If prop isn't found on frame's inner window, try its outer window. This mimics the behavior of Fx_window_property.

Make strings multibyte, to avoid problems with unibyte strings that are not valid UTF-8 (Bug#24206). Redo buffer allocation so that it is O(N), not O(N**2). Avoid going past the end of the input string when given invalid input. Avoid some unlikely problems in accessing the wrong storage after a GC.
