* lisp/net/sieve-manage.el
(sieve-manage-ignore-broken-tls): New user option.
(sieve-manage-open-server):
Don't test STARTTLS capability if the option is set (bug#24422).
This fixes the following warning:
frame.c: In function ‘x_set_frame_parameters’:
frame.c:3329:25: error: ‘width’ may be used uninitialized in
this function [-Werror=maybe-uninitialized]
adjust_frame_size (f, width_change ? width : -1,
^
* src/frame.c (x_set_frame_parameters): Drop width_changed and
height_changed variables in favour of storing that information in
width and height variables.
This fixes the following warning:
emacsclient.c: In function ‘set_local_socket’:
/usr/include/x86_64-linux-gnu/bits/string3.h:111:3: error:

^
emacsclient.c:1197:17: note: ‘tmpdir’ was declared here
const char *tmpdir;
* lib-src/emacsclient.c (set_local_socket): Get rid of use_tmpdir
variable and instead use tmpdir being non-NULL as sign that it should
be used.
Reverts commit ca473907
Add a defun to check if an executable exists, and call it
on each function using an external program: when the executable
is not available signal an error.
See discussion on:
https://lists.gnu.org/archive/html/emacs-devel/2016-09/msg00135.html
* lisp/image-dired.el (image-dired--check-executable-exists): New defun.
Throw and error when the executable arg is missing.
(image-dired-display-image, image-dired-rotate-thumbnail)
(image-dired-rotate-original, image-dired-set-exif-data)
(image-dired-get-exif-data):
Use it.
* 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.
Or, more clearly, when something looks like a function declaration and it's
inside a function, fontify it as a direct initialization.
For this purpose, introduce a "brace stack" for each buffer, where an entry on
the brace stack states how deeply nested a particular position is inside
braces inside a "top level", which includes classes and namespaces.
Also introduce a new "context", "top", with which c-font-lock-declarations
signals to c-forward-decl-or-cast-1 that point is at the top level.
* lisp/progmodes/cc-langs.el (c-get-state-before-change-functions): add
c-truncate-bs-cache.
(c-flat-decl-block-kwds, c-brace-stack-thing-key, c-brace-stack-no-semi-key)
(c-type-decl-operator-prefix-key): new language constants/variables.
* lisp/progmodes/cc-engine.el (c-bs-interval, c-bs-cache, c-bs-cache-limit)
(c-bs-prev-pos, c-bs-prev-stack): New mostly local variables for the brace
stack cache.
(c-init-bs-cache, c-truncate-bs-cache, c-truncate-bs-cache, c-brace-stack-at)
(c-bs-at-toplevel-p): New functions which manipulate the brace stack (cache).
(c-find-decl-prefix-search): Keep track of whether we're at top level.
(c-find-decl-spots): New local variable cfd-top-level which records what it
says. On calling cfd-fun, pass cfd-top-level as an additional argument.
(c-forward-declarator): Add new element DECORATED to the result list. Set it
to non-nil when a match for c-type-decl-operator-prefix-key is found.
(c-forward-decl-or-cast-1): Handle the newly introduced context "top".
Introduce "CASE 9.5", which recognizes direct initializations.
* lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare)
(c-font-lock-enum-tail, c-font-lock-cut-off-declarators)
(c-font-lock-enclosing-decls, c-simple-decl-matchers, c-basic-matchers-after):
Add appropriate `not-top' argument to calls to c-font-lock-declarators.
(c-font-lock-declarators): Additional parameter `not-top'. Use not-top to
participate in the decision whether to fontify an identifier as a function or
a variable.
(c-font-lock-declarations): The internal lambda function takes an additional
argument `toplev' from c-find-decl-spots, which it uses in determining the
"context" of a declaration. Add appropriate `not-top' argument to calls to
c-font-lock-declarators.
(c-font-lock-objc-methods): Add extra parameter to internal lambda function,
like for c-font-lock-declarators.
* lisp/progmodes/cc-mode.el (c-basic-common-init): Initialize the brace stack
cache.
For errors, use ‘byte-compile-report-error’ instead so that the error
is registered and causes compilation to fail (Bug#24359).
For warnings, use ‘byte-compile-warn’ instead so that
‘byte-compile-error-on-warn’ is honored (Bug#24360).
* lisp/emacs-lisp/macroexp.el (macroexp--funcall-if-compiled)
(macroexp--warn-and-return): Use ‘byte-compile-warn’ instead of
‘byte-compile-log-warning’.
* lisp/emacs-lisp/bytecomp.el (byte-compile-form, byte-compile-unfold-bcf)
(byte-compile-setq, byte-compile-funcall): Use
‘byte-compile-report-error’ instead of ‘byte-compile-log-warning’.
(byte-compile-log-warning): Convert comment to documentation
string. Explain that the function shouldn’t be called directly.
(byte-compile-report-error): Add optional FILL argument.
* lisp/emacs-lisp/cconv.el (cconv-convert, cconv--analyze-use)
(cconv--analyze-function, cconv-analyze-form): Use
‘byte-compile-warn’ instead of ‘byte-compile-log-warning’.
* lisp/emacs-lisp/byte-opt.el (byte-compile-inline-expand): Use
‘byte-compile-warn’ instead of ‘byte-compile-log-warning’.
* lisp/subr.el (add-to-list): Use ‘byte-compile-report-error’ instead
of ‘byte-compile-log-warning’.
(do-after-load-evaluation): Use ‘byte-compile-warn’ instead of
‘byte-compile-log-warning’.
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.
It is useful to be able to call `isearch-done' unconditionally to
ensure a non-isearching state.
* lisp/isearch.el (isearch-done): Check that `isearch--current-buffer'
is a live buffer before using it (Bug #21091).
* test/lisp/isearch-tests.el (isearch--test-done): Test it.
* lisp/emacs-lisp/ring.el (ring-elements): Don't use the RESULT
argument of `dotimes' when the iteration variable isn't referred by
it.
(ring-member): Don't pass nil as the RESULT argument of `dotimes'
since it's the default.
Having one test for all character classes it is not always trivial to
determine which class is failing. This happens when failure is caused
by ‘(should (equal (point) (point-max)))’ not being met.
With per-character class tests, it is immidiatelly obvious which test
causes issues plus tests for all classes are run even if some of them
fail.
* test/src/regex-tests.el (regex-character-classes): Delete and split
into…
(regex-tests-alnum-character-class, regex-tests-alpha-character-class,
regex-tests-ascii-character-class, regex-tests-blank-character-class,
regex-tests-cntrl-character-class, regex-tests-digit-character-class,
regex-tests-graph-character-class, regex-tests-lower-character-class,
regex-tests-multibyte-character-class,
regex-tests-nonascii-character-class,
regex-tests-print-character-class, regex-tests-punct-character-class,
regex-tests-space-character-class,
regex-tests-unibyte-character-class,
regex-tests-upper-character-class, regex-tests-word-character-class,
regex-tests-xdigit-character-class): …new tests.
* lisp/emacs-lisp/regexp-opt.el (regexp-opt-charset): Do not use
'case-table as charmap char-table’s property. The function has nothing
to do with casing and in addition using 'case-table causes unnecessary
extra slots to be allocated which ‘regexp-opt-charset’ does not use.
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.
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.
* 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.
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:

* 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.
This incorporates:
2016-09-07 flexmember: new macro FLEXALIGNOF
2016-09-07 flexmember: port better to GCC + valgrind
2016-08-18 Port modules to use getprogname explicitly
2016-09-02 manywarnings: add -fno-common
* admin/merge-gnulib (GNULIB_TOOL_FLAGS): Don’t avoid flexmember,
since time_rz now uses part of it. Instead, remove m4/flexmember.m4.
* configure.ac (AC_C_FLEXIBLE_ARRAY_MEMBER): Define away,
since Emacs assumes C99 and therefore removes m4/flexmember.m4.
* lib/euidaccess.c, lib/group-member.c, lib/time_rz.c:
* m4/manywarnings.m4: Copy from gnulib.
* lib/flexmember.h: New file, from gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lisp/startup.el (command-line-1): Only pass expanded FILENAME argument
of --load when it refers to a normal file, since `load' doesn't handle
directories (Bug #16406).
* lisp/calendar/icalendar.el (icalendar--read-element): Avoid a regex
stack overflow by not using regex to extract values from calendar
events. (Bug#24315)
* lisp/files.el (convert-standard-filename): Doc fix. (Bug#24387)
* etc/NEWS: Suggest a way for mirroring slashes where previously
'convert-standard-filename' was used.
* 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".
* 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)
* lisp/progmodes/cc-engine.el (c-syntactic-re-search-forward): `noerror' can
be given the values `before-literal' and `after-literal', so that when a
search fails, and the `bound' is inside a literal, point is left respectively
before or after that literal.
* 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.
* 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".

Passing the prefix argument as the 3rd argument to 'call-interactively'
causes the prefix argument to be interpreted as events, which is not
only wrong, but also causes a type error, as 'current-prefix-arg' can
never be a vector as 'call-interactively' expects. 'call-interactively'
automatically passes its prefix argument to the called function, so just
do that, eliminating faulty behavior.
