* src/data.c (arith_driver): Streamline fixnum division a bit
more, and add a comment about why overflow is impossible.
This responds to a private comment by Stefan Monnier.
This will allow js.el to work after maintenance changes in CC Mode, e.g. the
fix to bug #11165.
* lisp/progmodes/js.el (top level): Create a CC Mode derived language called
js-mode and based on Java Mode.
(js-mode): call c-init-language-vars for js-mode. Remove the direct settings
of several CC Mode language variables which are now defined through the
derived language mechanism. Call c-set-style and set up the needed style
variables c-block-comment-prefix and c-comment-prefix-regexp.
* time-stamp.el: Implement %:z as expanding to the numeric time zone
offset, to address the feature request of bug#32931. Do not document it
yet, to discourage compatibility problems in mixed Emacs 26 and Emacs 27
environments. Documentation will be added in a subsequent release at
least two years later. (We cannot yet use %z for numeric time zone
because in Emacs 26 it was documented to do something else.)
* time-stamp-tests.el (time-stamp-test-format-time-zone): expand this
test and break it into two tests, time-stamp-test-format-time-zone-name
and time-stamp-test-format-time-zone-offset.
* lisp/emacs-lisp/package.el (package-menu--refresh-archives): Rename
from duplicated name package-menu--refresh. (Bug#38084)
(package-menu-mode, list-packages): Use new name.
* src/data.c (arith_driver): Remove unnecessary runtime test,
since integer overflow is impossible on division of fixnums,
given that the worst case is MOST_NEGATIVE_FIXNUM / -1 which is
representable as an EMACS_INT (albeit not as a fixnum).
* lisp/emacs-lisp/package.el (package--activated): New variable to
avoid changing value of defcustom 'package-enable-at-startup'.
(package-initialize): Don't set 'package-enable-at-startup'.
(package-initialize, package-activate-all): Set 'package--activated'
instead of 'package-enable-at-startup'.
(package--initialized): Add doc string.
* lisp/startup.el (command-line): Check if 'package--activated' is
non-nil before activating packages.
* doc/lispref/package.texi (Packaging Basics): Update docs.
* lisp/emacs-lisp/package.el (package-menu--refresh): Rename from
'package-menu-refresh', make internal and non-interactive.
(package-menu-mode-map, package-menu-mode-menu, package-menu-mode)
(list-packages): Use the above. (Bug#35504)
(package-menu-refresh): Redefine as obsolete fuction alias for
'revert-buffer'.
* doc/emacs/package.texi (Package Menu): Document it.
* etc/NEWS: Announce it.
Suggested by Drew Adams.
* lisp/frame.el
(next-multiframe-window): Define as obsolete alias for...
(next-window-any-frame): ...new function name.
(previous-multiframe-window): Define as obsolete alias for...
(previous-window-any-frame): ...new function name. (Bug#12436)
* lisp/term/ns-win.el (global-map): Use new command name.
* doc/emacs/windows.texi (Other Window): Document it.
* etc/NEWS: Announce it.
Also don't send :error field on non-errors.
* lisp/jsonrpc.el (jsonrpc--reply): Don't send :result and :error
if none supplied.
(Version): Bump to 1.0.8
* lisp/tab-line.el (tab-line-tabs-function): Add option
tab-line-tabs-buffer-groups.
(tab-line-tabs-buffer-groups): New defvar defaulted to
mouse-buffer-menu-mode-groups.
(tab-line-tabs-buffer-groups--name, tab-line-tabs-buffer-groups):
New functions.
(tab-line-format): Support tabs in the format '(tab (name . "name") ...)'.
(tab-line-select-tab): Move part of code to tab-line-select-tab-buffer.
(tab-line-select-tab-buffer): New function.
(tab-line-tab-current): Rename from tab-line-tab-selected.
* lisp/net/network-stream.el
(network-stream-use-client-certificates): New user option.
(open-network-stream): If 'network-stream-use-client-certificates'
is t, and the user hasn't specified :client-certificate, do
certificate lookups via 'auth-source'.
(network-stream-certificate): Only return key and certificate
files that exist.
* doc/lispref/processes.texi (Network): Document new
client-certificate behavior.
* etc/NEWS: Document 'network-stream-use-client-certificates'.
* etc/NEWS: Mention this.
* doc/lispref/errors.texi (Standard Errors):
Document overflow-error, which was formerly undocumented.
It is a range error, not a domain error.
* src/data.c (syms_of_data): overflow-error and (undocumented)
underflow-error are subtypes range-error, not domain-error.
This fixes bugs in timezone-time-from-absolute and in
erc-ctcp-reply-PING.
Similarly for (expt 0 bignum) and (expt -1 bignum).
The result is always a -1, 0 or 1, so do not signal overflow.
* src/data.c (expt_integer): Do not signal an overflow if
-1 <= X <= 1. Be clearer about when overflow is signaled.
* test/src/floatfns-tests.el (bignum-expt): Test this.
(files.el subr.el): Fix some grammar errors in doc strings and comments.
(frame.c fringe.c image.c xfns.c xterm.c): Fix some English grammar
errors in doc strings.
* lisp/tab-bar.el (tab-bar-history-limit): Increase to 10 since wc
is not saved to the desktop file anymore, so doesn't affect its size.
(tab-bar-history--pre-change, tab-bar--history-change):
Store wc before possibly entering the minibuffer.
* lisp/tab-bar.el (frameset-filter-tabs): New function
added to 'frameset-filter-alist' for frame parameter 'tabs'.
(tab-bar--tab): Remove ws-bl/ws-bbl that are not needed because
frameset doesn't save frame buffer-list to desktop anyway.
(tab-bar-select-tab): Remove ws-bl/ws-bbl related code.
* lisp/emacs-lisp/seq.el (seq-reduce): Add autoload cookie.
* lisp/cus-edit.el (custom-group--draw-horizontal-line): New
function to draw horizontal lines which handles a non-nil value of
'truncate-lines'. (Bug#25308)
(custom-group-value-create): Use it.

* test/lisp/files-tests.el
(files-tests-file-name-non-special-start-file-process): On
MS-Windows, wait till the process dies before returning from
the files-tests--with-temp-non-special macro, to ensure the
temporary directory is successfully deleted.
* src/dired.c (scmp): Comment on (non)applicability to
comparisons of non-ASCII strings case-insensitively.
(file_name_completion): Decode early the file names read from
the directory, and use the decoded names for comparison when
letter-case should be ignored. (Bug#11339)
* lisp/international/mule-diag.el (describe-font): This function
can be used on unloaded fonts, so remove that restriction from the
doc string (bug#16815). Also allow completion over all fonts on
the system.
* src/font.c (Ffont_info): Ditto for the doc string.
Eglot, a third-party package which uses Flymake, has its own
diagnostic types such as 'eglot-error', 'eglot-warning', etc... While
not being too long, they will not fit in the type column of the "list
all diagnostics" buffer. This commit allows diagnostic types to have
user-defined names and also assigns names to the default categories.
* doc/misc/flymake.texi (Flymake error types): Describe
flymake-type-name prop.
* lisp/progmodes/flymake.el (flymake--diagnostics-buffer-entries):
Use type names.
(flymake-error, flymake-warning, flymake-note): Give these
diagnostic categories default type names.
This fixes bug #10149.
* lisp/progmodes/cc-fonts.el (c-font-lock-single-decl) Limit the search by
c-go-up-list-backwards to 500 non-literal characters.
