Introduce ‘c-lineup-ternary-bodies’ function which, when used as
a c lineup function, aligns question mark and colon of a ternary
operator. For example:
return arg % 2 == 0 ? arg / 2
: (3 * arg + 1);
* lisp/progmodes/cc-align.el (c-lineup-ternary-bodies): New function.
* doc/misc/cc-mode.texi (Operator Line-Up Functions): Document the
new function.
* test/lisp/progmodes/cc-mode-tests.el (c-lineup-ternary-bodies): New
test case.
* src/textprop.c (Fnext_single_char_property_change): Clarify in
the doc string the behavior when LIMIT is past the end of OBJECT.
Stop the search when position gets to end of buffer, for when LIMIT
is beyond that. (Bug#40000)
* lisp/net/browse-url.el (browse-url-handlers): Allow predicates for
matching in browse-url-handlers. Adapt docs and customize type.
(browse-url-select-handler): Support predicates in addition to
regexes.
(browse-url--non-html-file-url-p): New defun.
(browse-url-default-handlers): Use above predicate entry instead of
two entries.
* lisp/emacs-lisp/cl-macs.el (cl--parse-loop-clause): Put the temp-idx
increment in cl--loop-body, leaving just the side-effect free testing
of the index for both cl--loop-body and cl--loop-conditions.
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs-loop-and-arrays):
Extend test to cover this case.
It fails when using 'and' (parallel bindings) for arrays (Bug#40727).
* lisp/emacs-lisp/cl-macs.el (cl--parse-loop-clause): Revert to
recomputing array length.
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs-loop-and-arrays): New
test.
* lisp/dnd.el (dnd-handle-one-url): Don't require browse-url twice
in the same function. Declare non-autoloaded browse-url-handlers to
silence byte-compiler.
* lisp/net/browse-url.el (browse-url-default-handlers): Add a browser
handler for HTML page file:// URLs before the generic file:// handler.
(browse-url--browser): New defun.

deprecated alist choice of `browse-url-browser-function' and mention
`browse-url-handlers' and `browse-url-default-handlers'.

deprecated.

node.

browse-url-handlers.
* lisp/textmodes/sgml-mode.el (html-face-tag-alist): Prefer inserting
'strong' and 'em' tags to 'b' and 'i' in html-mode. (Bug#41031)
* lisp/textmodes/sgml-mode.el (html-mode): Update docstring to do the
same.

:failed.
Don't merge to master. The mentioned reverts are a safe-for-release
fix for Bug#40727.
Problem reported by Andreas Schwab in:
https://lists.gnu.org/r/emacs-devel/2020-05/msg00650.html
* src/conf_post.h (HAS_ATTR_no_sanitize): Define to false in case
cpp is picky, fixing a longstanding glitch here.
(ATTRIBUTE_NO_SANITIZE_ADDRESS, ATTRIBUTE_NO_SANITIZE_UNDEFINED):
Use HAS_ATTRIBUTE, not __has_attribute.
Do not merge to master.
*lisp/emacs-lisp/edebug.el (edebug--display-1)
(edebug-toggle-disable-breakpoint): Remove calls to
edebug--overlay-breakpoints and edebug--overlay-breakpoints-removed which had
been overlooked in a recent changed to edebug.
* lisp/fileloop.el (fileloop--case-fold):
Extract from existing code. Honor search-upper-case (bug#40940).
(fileloop-initialize-replace, fileloop-initialize-search): Use it.
Update the docstring.
* lisp/isearch.el (isearch-lazy-highlight-search): Remove recent fix of
lazy-highlighting of hidden matches. In emacs-27 leave only the fix for
lazy-counting of hidden matches when isearch-lazy-count is non-nil.
; Do not merge to master.
attribute.h is partly designed for C2X forward compatibility,
since C2X will add some standard attributes. Using its macros
should help insulate Emacs from C2X teething problems.
* src/conf_post.h: Include attribute.h.
(HAS_ATTRIBUTE, HAS_FEATURE): Rename from __has_attribute and
__has_feature, to avoid polluting the builtin namespace.
All uses changed.
(ATTRIBUTE_COLD, ATTRIBUTE_FORMAT, FALLTHROUGH, ATTRIBUTE_CONST)
(ATTRIBUTE_PURE, ATTRIBUTE_UNUSED, ATTRIBUTE_MAY_ALIAS)
(ATTRIBUTE_MALLOC, ATTRIBUTE_ALLOC_SIZE)
(ATTRIBUTE_RETURNS_NONNULL): Remove, as attribute.h does this now.
(NO_INLINE, EXTERNALLY_VISIBLE, ARG_NONNULL, ATTRIBUTE_UNUSED):
Simplify by defining in terms of attribute.h macros.
* src/systhread.h (ATTRIBUTE_WARN_UNUSED_RESULT): Remove.
All uses replaced by attribute.h’s NODISCARD.
