| | | | | | | | * src/window.c (window_scroll_pixel_based): Account for scroll-margin when scrolling down, i.e. moving window-start towards the beginning of the buffer. Reported by zhang cc <ccsmile2008@outlook.com> in http://lists.gnu.org/archive/html/emacs-devel/2017-12/msg00894.html.
* * src/buffer.c (Frestore_buffer_modified_p): Fix bug#29846Stefan Monnier2017-12-281-9/+11

| | | | | | | * src/fontset.c (free_realized_fontsets): Call recompute_basic_faces, so that the basic faces are available to any Lisp that calls this function, e.g. via set-fontset-font. (Bug#29632)
* Fix tool-tip display when display margins are non-zero by defaultEli Zaretskii2017-12-094-3/+26
| | | | | | | | | * src/buffer.h (bset_left_margin_cols, bset_right_margin_cols): New inline functions. * src/xfns.c (Fx_show_tip): * src/w32fns.c (Fx_show_tip): Force display margins of the tip buffer to zero, as it will be displayed in a pseudo-window, which doesn't support display margins.

| | | | | | | | This fixes a off-by-one buffer overrun bug introduced in 2017-06-04T15:39:37Z!eggert@cs.ucla.edu. Problem uncovered by an experimental version of Emacs built with -fcheck-pointer-bounds and running on Intel MPX hardware. * src/editfns.c (styled_format): Avoid overrunning internal buffers.

| | | | | | | | Problem discovered by configuring with --enable-gcc-warnings on Ubuntu 17.10 x86-64 with gcc (Ubuntu 7.2.0-8ubuntu3). * src/bytecode.c (exec_byte_code): Call the C error function instead of the Lisp one, so that the Emacs interpreter does not go haywire if the user redefines the Lisp error function.
* Improve documentation of "constant" symbolsEli Zaretskii2017-11-263-5/+12
| | | | | | | | | | | | | | | | * src/font.c (syms_of_font) <font-weight-table, font-slant-table> <font-width-table>: * src/data.c (syms_of_data) <most-positive-fixnum> <most-negative-fixnum>: * src/buffer.c (syms_of_buffer) <enable-multibyte-characters>: Mention in the doc strings that these variables are read-only. * doc/lispref/variables.texi (Creating Buffer-Local): Document that making a constant variable buffer-local signals an error. * doc/lispref/variables.texi (Constant Variables): * doc/lispref/errors.texi (Standard Errors): More accurate and up-to-date documentation of which symbols cannot be assigned values.

* Tweak copy-file, rename-file docPaul Eggert2017-11-251-8/+4
| | | | | | | | * src/fileio.c (Fcopy_file, Frename_file): Tweak the recent change slightly, as NEWNAME is treated as a directory name depending only on the contents of the NEWNAME string, and independently of whether NEWNAME names a directory (i.e., whether the directory exists) (Bug#29362).

* Fix divider frame params on NS (bug#29352)Alan Third2017-11-191-0/+4
| | | | | * src/nsfns.m (Fx_create_frame): Set right-divider-width and bottom-divider-width parameters.
