Without these changes, Emacs does not build on Fedora 26 x86-64
when configured --with-x-toolkit=no --enable-gcc-warnings.
* oldXMenu/Activate.c (XMenuActivate): Add FALLTHROUGH.
* src/xterm.c (x_dispatch_event): Define only if
USE_X_TOOLKIT || USE_MOTIF || USE_GTK.
* lisp/files.el (find-file, find-file-other-window)
(find-file-other-frame): Mention file-name-at-point-functions in
the doc string. Reported by Florian Weimer <fw@deneb.enyo.de> in
http://lists.gnu.org/archive/html/emacs-devel/2017-11/msg00224.html.
* doc/emacs/mini.texi (Minibuffer History): Document
file-name-at-point-functions and its effect on M-n when typing
file names in the minibuffer.
* doc/emacs/files.texi (File Names):
* doc/emacs/mini.texi (Minibuffer File): Add a cross-reference to
"Minibuffer History", where special features of M-n regarding
files are described.
* lisp/desktop.el (desktop-read): Use toplevel value of
window-configuration-change-hook when deciding whether desktop
auto-saving is enabled. Suggested by Peter Neidhardt
<pe.neidhardt@googlemail.com>. (Bug#28945)
Evidently nobody builds Emacs with --enable-checking=all,
which is no surprise as it is so slow as to be unusable nowadays.
Perhaps we should remove the slowest checks, or move them into
another category, or speed them up, or something.
* src/alloc.c (SDATA_SIZE) [GC_CHECK_STRING_BYTES]: Fix off-by-one
error in size calculation, which caused a failure when
--enable-checking=stringbytes was used. I introduced this bug in
2016-09-08T01:08:45!eggert@cs.ucla.edu "Port flexible array
members to GCC + valgrind".
* lisp/progmodes/cc-engine.el (c-looking-at-statement-block): Amend so that
if there is only syntactic whitespace in a brace block, it is regarded as a
statement block. Also, if there is no semicolon or comma delimiter, treat as
a statement block when there is a keyword.
(c-guess-basic-syntax): CASE 9 test: Regard a brace as starting a brace block
when its contents indicate a brace block.
* src/xdisp.c (should_produce_line_number) [USE_GTK]: Make sure
tip_frame is indeed a tooltip frame, before disabling line numbers
on it. (Bug#27647)
* src/dispextern.h (tip_frame): Add commentary describing the
kludgey usage of this variable in GTK builds.
If a line/column pair indicates an end-of-buffer position, flymake
should behave like the case where the last line of the buffer is
referenced without a column indication. This behavior is currently
to highlight the whole last line.
* lisp/progmodes/flymake.el (flymake-diag-region): Correct
conditions of fallback to the fallback-eol local function.
The function checkdoc-current-buffer may error if there are unbalanced
parens, for example, but this shouldn't disable the
elisp-flymake-checkdoc backend.
* lisp/progmodes/elisp-mode.el (elisp-flymake-checkdoc): Use
ignore-errors.
In particular, don't indent contained brace lists in "staircase" fashion.
This fixes bug #28623.
* lisp/progmodes/cc-engine.el (c-looking-at-or-maybe-in-bracelist): When
testing for being enclosed in parens, recognise also a brace directly
following a comma, as well as a brace being the first thing inside the paren.
Enhance the return value, by indicating when we're directly inside an open
paren.
(c-inside-bracelist-p): Add an extra argument ACCEPT-IN-PARAM which indicates
whether we will accept a bracelist directly inside an open parenthesis.
Simplify the manipulation of PAREN-STATE by dispensing with variable LIM and
using c-pull-open-brace. Enhance the return value, respecting the new argument.
(c-guess-basic-syntax): Save a copy of the initial parse-state in the new
variable STATE-CACHE. Use this variable in place of C-STATE-CACHE throughout
the function. At CASE 7B, call c-inside-bracelist-p with extra argument nil.
At CASE 9, call that function with extra argument t.
* src/xdisp.c (try_window_reusing_current_matrix)
(try_cursor_movement): Disallow these optimizations if the buffer
has overlay arrow(s) shown on the fringe(s). (Bug#29198)
Problem reported by Damien Cassou (Bug#29223).
* lisp/url/url-cookie.el (url-cookie-expired-p):
Fix typo in previous change, which caused unexpired cookies
to be treated as expired and vice versa.
Apparently GCC requires that ‘__attribute__ ((aligned (8)))’ must
immediately follow the ‘struct’ keyword when aligning a structure.
The attribute silently does not work if it follows a tag after the
‘struct’ keyword. Who knew? Anyway, this patch is designed to
fix a SIGSEGV problem reported by John Mastro (Bug#29183).
* lib-src/make-docfile.c (close_emacs_globals):
* src/buffer.c (buffer_defaults, buffer_local_symbols):
* src/lisp.h (DEFUN):
* src/thread.c (main_thread):
Put 'GCALIGNED' immediately after 'struct'.
* lisp/org/org-clock.el (org-clock--oldest-date): Fix an issue
when compiling on macOS 10.6 with a western time zone (a
continuation of Bug#27736). In particular, see:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27736#74
and the first commit that attempted to work around this problem,
"Workaround for faulty localtime() under macOS 10.6", bd49b6f1 of
2017-09-30.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-convert-list-to-object):
Starting to phase out the printing of object names in
`object-write', handle either case.
* lisp/minibuffer.el (completion-table-with-predicate): Don't act as
if strict is non-nil when pred2 is nil (Bug#27841).
* test/lisp/minibuffer-tests.el
(completion-table-with-predicate-test): Add a test for Bug#27841.
* lisp/newcomment.el (comment-region-internal): Previously, the
comment text had to contain at least one line break character for the
ending extra line to be added. Make the behavior more consistent by
looking for end of line instead.
(comment-region-internal): Remove trailing white space from the
comment's initial line.
Copyright-paperwork-exempt: yes
* doc/lispref/text.texi (Auto Filling): Add reference to Emacs
manual. Add description of 'comment-auto-fill-only-comments'.
* etc/NEWS: Mention new treatment of
'comment-auto-fill-only-comments'.
* lisp/net/tramp.el (tramp-autoload-file-name-handler): Load Tramp only if
`tramp-mode' is non-nil.
(tramp-unload-file-name-handlers): Unload also
`tramp-autoload-file-name-handler'.
* test/lisp/net/tramp-tests.el (tramp-test42-delay-load): Extend test.
According to the virtualenv docs only POSIX systems follow the
structure "/path/to/venv/bin/", while windows systems use
"/path/to/venv/Scripts" for the location of the binary files, most
importantly including the python interpreter (see:
https://virtualenv.pypa.io/en/stable/userguide/#windows-notes).
* lisp/progmodes/python.el (python-shell-calculate-exec-path): Use the
"/path/to/venv/Scripts" for `windows-nt' machines.
