This new backend allows gnus to handle arbitrary sets of messages
spanning multiple groups, even when these groups are from different
backends and different servers. All gnus glue is removed from
nnir (leaving only the backend search functions) and gnus
search-related processing is done through nnselect. In appropriate
places 'nnir' has been replaced by 'nnselect' or 'search'.
* etc/NEWS: Document the change.

Buffers `*Shell Command Output*' and `*Async Shell Command*'
have been around since a long time; used across several libraries,
they are de facto output buffers for shell commands.

completing over the parts in the first article in the list of the
process-marked articles (bug#39543).

configuration changes before killing off the summary buffer, so
that the window conf machinery can return to a group-only
configuration (bug#40069).
* lisp/gnus/gnus-sum.el (gnus-summary-prepare-threads): Simplify both
the dummy root and the following article before comparing them,
otherwise both the former and the latter might display the thread's
subject even when gnus-summary-line-format contains "%s" (bug#40520).
From a patch privately suggested by Mattias Engdegård on 2020-05-11
in a followup to Bug#40671.

'gnus-shorten-url' (used by 'gnus-summary-browse-url') ignored
fragment identifiers and didn't check substring bounds, in some cases
leading to runtime errors, e.g.:
(gnus-shorten-url "https://some.url.with/path/and#also_a_long_target" 40)
;; => Lisp error: (args-out-of-range "/path/and" -18 nil)
This commit makes it account for #fragments and fixes faulty string
computation, reusing existing helper function. (bug#39980)
* lisp/vc/ediff-init.el (ediff-truncate-string-left): Rename to
'string-truncate-left' and move...
* lisp/emacs-lisp/subr-x.el (string-truncate-left): ...here.
All callers changed.
* lisp/gnus/gnus-sum.el (gnus-shorten-url): Fix args-out-of-range
error, don't drop #fragments, use 'string-truncate-left'.
This makes the accessors into (inlined) functions (instead of macros),
which simplifies some uses, and it makes the gnus-info-set-<foo>
macros redundant since we can use `setf` instead. Remove them and
update all users.
(gnus-info-group, gnus-info-rank, gnus-info-read, gnus-info-marks)
(gnus-info-method, gnus-info-params): Auto-defined by defstruct.
(gnus-info-level, gnus-info-score): Define as a function. Add gv-setter.
(gnus-info-set-group, gnus-info-set-rank, gnus-info-set-read): Remove,
use `setf` instead.
(gnus-info-set-marks, gnus-info-set-method, gnus-info-set-params):
Define as a function.
(gnus-info-set-entry): Delete function.
(gnus-info--grow-entry): New function, extracted from it.
(gnus-info--set-level, gnus-info--set-score): New functions, extracted
from the `gnus-info-set-level` and `gnus-info-set-score` which they replace.
(gnus-get-info): Define as a function.
* lisp/gnus/gnus-group.el (gnus-group-edit-group-done):
Use the `extend` arg of `gnus-info-set-method`.
(gnus-group-sort-selected-flat): eta-reduce.
* lisp/gnus/gnus-sum.el (gnus-summary-mode-map,
gnus-summary-article-map): Backtab should call
gnus-summary-button-backward, not gnus-summary-widget-backward.
* lisp/gnus/gnus-sum.el (gnus-thread-hide-subtree): Make the
"Non-nil" predicate do what it's supposed to (i.e., return non-nil
on non-nil values (excepting predicates)) (bug#37916).
* lisp/gnus/gnus-sum.el (gnus-mark-xrefs-as-read): There's already a
local binding for "group", don't need another "name". This was left
over from the obarray-to-hashtable change.
This completes the process started in c1b63af445. Gnus group names are
now fully decoded inside the Gnus system.
* lisp/gnus/gnus-agent.el (gnus-agent-file-coding-system): Change
default to utf-8-emacs.
(gnus-agent-decoded-group-names, gnus-agent-decoded-group-name):
Remove variable and function. Remove all usage in this file.
* lisp/gnus/gnus-cache.el (gnus-cache-decoded-group-names,
gnus-cache-unified-group-names, gnus-cache-decoded-group-name):
Remove these variables and function. Remove all usage in this file.
* lisp/gnus/gnus-group.el (gnus-tmp-decoded-group): Remove this
variable, gnus-tmp-group is now decoded.
(gnus-group-completing-read): Don't encode or decode group names
here.

* lisp/gnus/gnus-srvr.el (gnus-browse-foreign-server): Decode group
names here.
* lisp/gnus/gnus-start.el (gnus-make-hashtable-from-newsrc-alist):
check for encoded group names and decode.
(gnus-active-to-gnus-format): Make sure incoming group names are
decoded.
(gnus-read-newsrc-el-file): Check for encoded group names in
gnus-topic-alist.
* lisp/gnus/nnagent.el: Don't use a unibyte buffer.
* lisp/gnus/nnheader.el (nnheader-file-coding-system): Switch default
from 'raw-text to 'undecided, on the assumption that 'undecided will
probably write 'utf-8-emacs unless the user has arranged things
otherwise.
* lisp/gnus/nnimap.el (nnimap-decode-gnus-group,
nnimap-encode-gnus-group): Remove functions and their use.
* lisp/gnus/nnmail.el (nnmail-parse-active): Remove encoding.

* lisp/gnus/nnrss.el: Stop using gnus-group-decoded-name in all these
files.
This patch also moves the internal/external browser logic from
shr to browse-url, where it belongs more naturally.
* doc/misc/eww.texi (Basics): Adjust to browse-url-external-browser.
* doc/misc/gnus.texi (Article Commands): Ditto.
* lisp/gnus/gnus-art.el (gnus-button-url-regexp): Default to
`browse-url-button-regexp', which has taken over the definition
previously enjoyed by this variable.
* lisp/gnus/gnus-sum.el (gnus-summary-browse-url): Adjust usage.
* lisp/net/browse-url.el (browse-url--browser-defcustom-type): New
internal variable...
(browse-url-browser-function, browse-url-external-browser): Used
by these two; the latter of which is a new variable.
(browse-url-botton-regexp): New variable.
(browse-url-button-map): New keymap.
(browse-url-button): New face.
(browse-url-add-buttons): New function to add clickable browse-url
buttons to almost any buffer.
(browse-url-button-open): New command.
(browse-url-button-copy): New command.
* lisp/net/eww.el (eww-browse-with-external-browser)
(eww-follow-link): Adjust usage.
* lisp/net/shr.el (shr-external-browser): Make an obsolete alias
of `browse-url-external-browser'.
(shr-browse-url): Adjust usage.
* lisp/gnus/gnus-sum.el (gnus-summary-browse-url): Don't force
article conf, because the command may be called from the article
buffer (which may be the only buffer displayed).
* doc/misc/gnus.texi (Article Commands): Document new behaviour.
* lisp/gnus/gnus-sum.el (gnus-shorten-url): New function.
(gnus-summary-browse-url): Change function to make `C-u' use the
external browser (as Gnus does when you hit URLs manually). Don't
use an initial input.
* lisp/gnus/gnus-sum.el (gnus-collect-urls-primary-text): Add defcustom.
(gnus-collect-urls): Use it.
(gnus-summary-browse-url): Mention it in the docstring.
* lisp/gnus/gnus-sum.el (gnus-collect-urls): Make sure that
the URL labeled "Link" is the first in the return list.
(gnus-summary-browse-url): Use the 1st URL as the default.
* lisp/wid-edit.el (widget-text): New function.
* lisp/gnus/gnus-sum.el (gnus-collect-urls): Extract from ...
(gnus-summary-browse-url): Use it here.
Extracting URLs from an article will be useful in BBDB interaction.
* lisp/gnus/gnus-sum.el (gnus-summary-browse-url): New command for
browsing URLs from the article buffer from the summary buffer.
(gnus-summary-mode-map): Bind to "w".
(gnus-summary-article-map): And to "A w".
* doc/misc/gnus.texi (Article Commands): Document.
* lisp/gnus/gnus-async.el (gnus-async-with-semaphore): Use `declare`.
(gnus-async-prefetch-next): Don't assume gnus-data-number == car.
* lisp/gnus/gnus-sum.el (gnus-data-find-in): New function.
(gnus-data-find, gnus-data-find-list): Use it.
(gnus-summary-article-subject): Make it a function.
(gnus--dummy-data-list): New const.
(gnus-update-summary-mark-positions): Use it.
The recent change to use lexical-binding introduced a bug because
gnus-summary-line-format-alist refers to variable `thread` which is now
lexical and hence not available there any more. Replace it with
a dynamically scoped var `gnus-tmp-thread` as was already done with
all other vars.
(gnus-summary-line-format-alist): Use it instead of `thread`.
(gnus-summary-prepare-threads): Bind it around call to (eval
gnus-summary-line-format-spec).
Use `mail-header-p` and `make-full-mail-header` instead of `vectorp` and
`vector`, respectively.
* lisp/gnus/message.el (message-cite-original-1, message-reply)
(message-followup):
* lisp/gnus/gnus-sum.el (gnus-get-newsgroup-headers):
Use make-full-mail-header instead of `vector`.
(gnus--dummy-mail-header): New const, using make-full-mail-header.
(gnus-update-summary-mark-positions): Use it instead of
an immediate vector.
(gnus-set-mode-line, gnus-summary-article-pseudo-p)
(gnus-summary-article-subject, gnus-summary-insert-subject)
(gnus-summary-find-subject, gnus-summary-goto-subject)
(gnus-summary-limit-to-age, gnus-summary-find-matching)
(gnus-summary-mark-article-as-unread, gnus-summary-mark-article)
(gnus-summary-save-article):
* lisp/gnus/gnus.el (gnus-news-group-p): Use mail-header-p instead
of vectorp.
This also has the side effect that the accessors are now defined as proper
functions rather than as macros, so they can be passed to `mapcar` etc..
* lisp/gnus/nnheader.el (mail-header-number, mail-header-subject)
(mail-header-from, mail-header-date, mail-header-id)
(mail-header-references, mail-header-chars, mail-header-lines)
(mail-header-xref, mail-header-extra): Define via cl-defstruct.
(mail-header-set-number, mail-header-set-subject)

(mail-header-set-message-id, mail-header-set-references)
(mail-header-set-chars, mail-header-set-lines, mail-header-set-xref)
(mail-header-set-extra): Remove, use `setf` instead. All callers adjusted.
* lisp/gnus/gnus-sum.el (gnus-select-newsgroup)
(gnus-summary-pop-limit, gnus-summary-limit-mark-excluded-as-read)
(gnus-summary-find-matching, gnus-find-matching-articles):
* lisp/gnus/gnus-kill.el (gnus-apply-kill-file-internal, gnus-execute):
* lisp/gnus/gnus-score.el (gnus-score-adaptive):
Eta-reduce, now that mail-header-FIELD are functions.
(gnus-summary-make-menu-bar, gnus-summary-display-make-predicate)
(gnus-summary-refer-thread, gnus-summary-find-matching)
(gnus-summary-edit-article, gnus-summary-sort):
Replace backquoted lambda with closure.
(gnus-summary-article-header): Use define-inline rather than defmacro,
so it's also a function.
(gnus-save-hidden-threads, gnus-summary-iterate, gnus-with-article):
Use `declare`.
(gnus-thread-sort-by-random): Simplify.
(gnus-summary-display-article, gnus-summary-limit-to-address):
Hoist common code outside of `if`.
* lisp/gnus/gnus-sum.el (gnus-summary-widget-forward)
(gnus-summary-widget-backward): Signal more informative error if
article window is not found. Consider other frames displaying
article buffer, and raise its frame before navigating its
widgets. (bug#35565)
* lisp/gnus/gnus-win.el (gnus-get-buffer-window): Simplify and add
docstring.
