* lisp/so-long.el: New library.
* doc/emacs/trouble.texi (Long Lines): New node covering so-long.el.
* doc/emacs/emacs.texi (Top): Add menu entry for the Long Lines node.
* etc/NEWS: Include under "New Modes and Packages in Emacs 27.1"
This speeds up ‘make compile-always’ by 0.1% on my platform.
Suggested by Pip Cet in:
https://lists.gnu.org/r/emacs-devel/2019-07/msg00257.html
* src/.gdbinit (pwinx, pgx, xbuffer, xprintstr):
Output dead_object () as "DEAD".
* src/alloc.c (Vdead, DEADP): Remove.
All uses replaced by dead_object () / deadp.
(deadp): New function.
(init_alloc_once_for_pdumper): Remove no-longer-needed
initialization.
* src/lisp.h (dead_object): New function.
* doc/emacs/maintaining.texi (VC Directory Commands): Document it.
* lisp/vc/vc-dir.el (vc-dir-delete-files-no-vc): New command and
keystroke (bug#31732).
* lisp/dired.el(dired-in-this-tree-p): Rename from `dired-in-this-tree'.
Add docstring.
(dired-in-this-tree): Define an alias to `dired-in-this-tree-p'.
(dired-buffers-for-dir)
* lisp/dired-aux.el (dired-tree-down, dired-kill-tree)
(dired-insert-subdir, dired-rename-subdir): Update all callers (bug#32892).
* doc/lispref/text.texi (Interpolated Strings): New section.
* lisp/format-spec.el (format-spec--parse-modifiers)
(format-spec--pad): New functions.
(format-spec): Support more format modifiers (bug#32931).
* lisp/epg.el (epg-start-encrypt)
* lisp/gnus/mml-sec.el (mml-secure-epg-encrypt): When
'mml-secure-openpgp-sign-with-sender' is non-nil message sender's
email address (in addition to its old behaviour) will also be used
to set gpg's "--sender email@domain" option.
* lisp/emacs-lisp/ert.el (ert-summarize-tests-batch-and-exit):
Always include the number of failed tests, because absence of the
text is not reassuring (bug#36616).
* lisp/gnus/nnimap.el (nnimap-login): When base64-ing
credentials, don't let bsae64-encode-string split the result into
several lines, because servers do not understand that (bug#34458).
* lisp/url/url-auth.el (url-basic-auth): When base64-ing
credentials, don't let bsae64-encode-string split the result into
several lines, because servers do not understand that (bug#36619).
is used instead of `font-lock-ensure' (bug#36564).
* test/lisp/progmodes/compile-tests.el (compile-test-error-regexps)
(compile-test-grep-regexps): Check the number of errors.
* lisp/mail/rfc2047.el (rfc2047-fold-region): Don't break lines
right after the Header: field, but wait until the next
whitespace. (This only makes a difference for words that are very
long (i.e., longer than, say, 60 characters, depending on the
header name length.)
* lib-src/make-docfile.c (compare_globals):
Make symbols 1 through 4 be t, unbound, error, lambda.
This is in addition to symbol 0 being nil.
This change improved ‘make compile-always’ performance by 0.6%
on my platform.
* src/fns.c (string_version_cmp): New function.
This has most of the old Fstring_version_lessp,
with an assertion to make things a bit clearer.
* src/fns.c (Fstring_version_lessp):
* src/keymap.c (describe_map_compare): Use it (Bug#33237).
* lisp/replace.el (perform-replace): Don't wrap replace-highlight
in save-match-data. Use `(nth 0 real-match-data)' instead of
`(match-beginning 0)' after replace-highlight. (Bug#36328)
* lisp/format-spec.el (format-spec): Allow passing through format
strings that have no specs (to be able to act as a filter). Also
add an example.
* test/lisp/format-spec-tests.el (test-format-spec): Add tests for
the new functionality.
* src/fileio.c (Fexpand_file_name): Clarify that "~" in NAME is
expanded, and not just "~/". Also clarify that ~USER is not
expanded if USER doesn't exist (bug#36490).
* src/keymap.c (describe_map_compare): Change the sorting order of
keystrokes, so that we get the order <f1> <f2> <f11> instead of
<f1> <f11> <f2> (bug#33237).
* lisp/progmodes/elisp-mode.el (eval-sexp-add-defvars): When
collecting defvars in the current buffer, ignore the ones that are
in comments or strings (bug#34233).
* src/image.c (syms_of_image) <Qgio> [HAVE_NTGUI]: New DEFSYM.
(init_svg_functions) [LIBRSVG_CHECK_VERSION >= 2.32.0]: Load
g_file_new_for_path and g_memory_input_stream_new_from_data
from libgio, not from libglib. (Bug#35548)
* lisp/term/w32-win.el (dynamic-library-alist): Add the libgio
DLL.
* src/xdisp.c (resize_mini_window): Always reset the
mini-window's start point to the beginning of the buffer, even
if resizing is not needed. This avoids assertion violations
when resize-mini-windows is nil. (Bug#36595)
* src/image.c (init_svg_functions) [WINDOWSNT]:
Load the pre-2.32 or 2.32 functions,
depending on LIBRSVG_CHECK_VERSION.
(svg_load_image): In librsvg 2.32 or later, use
g_memory_input_stream_new_from_data, g_file_new_for_path and
rsvg_handle_new_from_stream_sync rather than the
deprecated-in-2.45 rsvg_handle_write and rsvg_handle_close.
From a patch by YAMAMOTO Mitsuharu (Bug#35548#11).
* lisp/calc/calc-alg.el (calcFunc-sec, calcFunc-csc, calcFunc-cot):
Check that `math-known-sin' and `math-known-tan' succeeded before
using their value in arithmetic.
* test/lisp/calc/calc-tests.el (calc-test-trig): Add regression tests.
