* src/fileio.c (Fexpand_file_name): Don't build multibyte strings
from unibyte non-ASCII strings when NAME and DEFAULT_DIRECTORY
have different multibyteness, as this adds bytes to the byte
sequence, and in some situations, e.g., when the home directory
includes non-ASCII characters, can fail file APIs. (Bug#30755)
* lisp/startup.el (normal-top-level): Make sure default-directory
is set to a multibyte string when decoded on MS-Windows.
(cherry picked from commit 3aab8626ba5080bb04d0fdae52d99c850a842a52)
* lisp/textmodes/ispell.el (ispell-pdict-save): Don't restart
flyspell-mode, as bug#11963, which this was supposed to fix, is
fixed better by ispell-command-loop, when the user types 'i' or
'a'. Restarting Flyspell mode when the personal dictionary is
saved caused bug#31372 as side effect.
(ispell-command-loop): Test 'flyspell-mode', not whether
flyspell-unhighlight-at is fboundp, to determine whether Flyspell
mode is turned on in the current buffer.
(flyspell-unhighlight-at): Add declare-function form for it.
(cherry picked from commit 91e582a31ada28fab5ae55bdbf959a9d30796587)
* src/font.c (font_open_entity): Fail after 15 iterations through
the loop that looks for a font whose average_width and height are
both positive. This avoids infinite loops for fonts that, e.g.,
report average_width of zero for any possible size we try.
(Bug#31316)
(cherry picked from commit e2879c1f837059335af89022b2a9ac9bc861e96d)
* lisp/international/fontset.el (font-encoding-alist): Fix the
GB18030 entry to encode characters correctly when passing them to
the xfont back-end. (Bug#31315) See also
http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg00754.html.
(cherry picked from commit bbe2cadc544e63e9378350621887f8fb9bbcc236)
* src/xdisp.c (move_it_in_display_line_to): Avoid looping in
previous/next-line when wrap-prefix is set to a too-wide
stretch of whitespace. (Bug#30432)
(cherry picked from commit 842b3d7412eaed6b2c9f90c3361abb4932ec0b1d)
* src/xdisp.c (display_line): Avoid looping in redisplay when
wrap-prefix is set to a too-wide stretch of whitespace.
(Bug#30432)
(cherry picked from commit 2a1fe08307402d6217d073f8ab7737750d253dd4)
* src/xdisp.c (pos_visible_p): For the leftmost glyph, adjust the X
coordinate due to line-number display. (Bug#30834)
(cherry picked from commit 4a20174d7949028f66b18a92a75d6b74194242a8)
* src/xdisp.c (Fwindow_text_pixel_size): Adjust the return value
when we stop one buffer position short of TO. (Bug#30746)
(cherry picked from commit 33cba5405c724566673cf023513bfb1faa963bea)
* src/xdisp.c (move_it_to): Initialize the line_number_produced_p
flag before iterating on a new line. (Bug#30818)
(cherry picked from commit 5c585b8b994aad4e6844f8eed80bdfbb396e91bf)
* src/xdisp.c (Fwindow_text_pixel_size): Correct the result when
there's a display property at the TO position, and the call to
move_it_to overshoots. (Bug#30746)
(cherry picked from commit 50e2c0fb5180a757d8d533518f68837ffe5909be)
* src/dispextern.h (struct it): New members tab_offset and
line_number_produced_p.
* src/xdisp.c (display_line): Don't set row->x to a negative value
if line numbers are being displayed. (Bug#30582)
Reset the line_number_produced_p flag before laying out the glyph
row.
(x_produce_glyphs): Use the line_number_produced_p flag to decide
whether to offset the X coordinate due to line-number display.
Use the tab_offset member to restore the original TAB width for
alignment purposes.
(move_it_in_display_line_to): Don't produce line numbers when moving
in hscrolled window to the left of first_visible_x.
(maybe_produce_line_number): Set the line_number_produced_p flag.
(Bug#30584)
* src/term.c (produce_glyphs): Correct TAB width only when
line_number_produced_p flag is set.
(cherry picked from commit 1ac190553886ff20817d3dd218464e2fc6f9e42a)
* src/process.c (read_process_output): Track bytes read from
a process.
(wait_reading_process_output): If called recursively through
timers and/or process filters via accept-process-output, it is
possible that the output of wait_proc has already been read by
one of those recursive calls, leaving the original call hanging
forever if no further output arrives through that fd and no
timeout has been set. Fix that by using the process read
accounting to keep track of how many bytes have been read and
use that as a condition to break out of the infinite loop and
return to the caller as well as to calculate the proper return
value (if a wait_proc is given that is).
* src/process.h (struct Lisp_Process): Add nbytes_read to track
bytes read from a process.
(cherry picked from commit 4ba32858d61eee16f17b51aca01c15211a0912f8)
* src/dispnew.c (buffer_posn_from_coords): Improve commentary.
* src/xdisp.c (move_it_in_display_line_to): Don't exit the loop
under truncate-lines if the glyph at TO_CHARPOS was not yet
produced. This avoids bailing out too early when we are at
TO_CHARPOS, but didn't yet produce glyphs for that buffer
position, because the last call to PRODUCE_GLYPHS at this position
was for an object other than the buffer. For further details, see
http://lists.gnu.org/archive/html/emacs-devel/2018-01/msg00537.html.
(cherry picked from commit c0154ac7c3423f68d8f3a2e85a756c9759219039)
The check-syntax target is enabled the use of Flymake's "legacy"
backend, flymake-proc-legacy-flymake in src/*.c. It works quite well
with C sources. The green light for this change had already been
given some time ago in
https://lists.gnu.org/archive/html/emacs-devel/2017-10/msg00385.html
* src/Makefile.in (check-syntax): New target.
(.PHONY): Add check-syntax.
* doc/lispintro/emacs-lisp-intro.texi (Wrong Type of Argument)
(debug, debug-on-entry, Void Function, Void Variable): Update the
*Backtrace* buffer display to current Emacs. (Bug#31654)
* doc/emacs/files.texi (Interlocking): Point user at detailed
file locking description in lisp reference manual. Add index
entry for '.#' to improve disoverability of information about locking.
* doc/lispref/files.texi (File Locks): Describe in detail what
the form of the lock file is. Add index entry for '.#' to
improve disoverability of information about locking.
* src/filelock.c (create-lockfiles): Add cross reference to
file locking in user manual and to 'lock-buffer'. Add string
'.#' to help users find the doc string.
* doc/lispref/files.texi (Contents of Directories): Fix inaccurate
description of the return value of directory-files-and-attributes.
* src/dired.c (Fdirectory_files_and_attributes): Describe the
function's value in more detail.
* lisp/progmodes/cc-mode.el (c-before-change-check-unbalanced-strings): Before
going back a sexp from the \n marked with a string-fence syntax-table text
property, check that it is indeed a \n. If not, simply delete that text
property from the isolated quote, not the quote and the \n which otherwise
delimit an unterminated string. Should we encounter a double quote marked
with a string-fence syntax-table text property at the end of the last line,
remove that property.
