* doc/misc/message.texi (Forwarding): Document it.
* lisp/gnus/message.el (message-forward-ignored-headers): Improve
documentation.
(message-forward-included-headers): Ditto.
(message-forward-included-mime-headers): New user option.
(message-remove-ignored-headers): Use it to preserve the necessary
MIME headers.
(message-forward-make-body): Remove headers when forwarding as
MIME, too.
* lisp/gnus/message.el (message--syntax-propertize): Use the
correct Message mode syntax table to avoid having
`message-cite-prefix-regexp' trigger very heavy backtracing when
called from an abbrev context (which defines "_" as a word
constituent) (bug#45944).
* lisp/gnus/nntp.el (nntp-send-authinfo): Don't signal an
`nntp-authinfo-rejected' error, because that will stop Gnus
startup (bug#45855). Instead signal an error that will be caught
higher up.
Previously, all Gnus backends returned header information by writing
nov lines into the nntp-server-buffer, which was later parsed. This
commit allows the backends to return their header information as a
list of already-parsed headers, though so far none of the backends
actually do that. The agent, cache, cloud etc. now operate on parsed
headers rather than nov text, ie. they use gnus-fetch-headers instead
of gnus-retrieve-headers.
* lisp/gnus/gnus-sum.el (gnus-fetch-headers): Handle the case in which
gnus-retrieve-headers returns headers directly.
* lisp/gnus/nnvirtual.el (nnvirtual-retrieve-headers): Use
gnus-fetch-headers rather than gnus-retrieve-headers to get headers,
meaning we're operating on already-parsed headers.
(nnvirtual-convert-headers): Remove now-unnecessary function.
(nnvirtual-update-xref-header): Rewrite to operate on parsed header.
* lisp/gnus/gnus-cloud.el (gnus-cloud-available-chunks): Use
gnus-fetch-headers instead of gnus-retrieve-headers.
* lisp/gnus/gnus-cache.el (gnus-cache-retrieve-headers): Use
gnus-fetch-headers.
(gnus-cache-braid-nov, gnus-cache-braid-heads): Delete unnecessary
functions -- we now do this work on a list of parsed headers.
* lisp/gnus/gnus-agent.el (gnus-agent-retrieve-headers): Use
gnus-fetch-headers.
(gnus-agent-braid-nov): Remove unnecessary function.
(gnus-agent-fetch-headers): Use gnus-fetch-headers.
* lisp/gnus/gnus-search.el (gnus-search-imap-search-keys): Add missing
keys "old", "new", "or" and "not".
(gnus-search-run-search): In addition, don't touch the query if it
starts with a parenthesis. Consider just getting rid of this
convenience altogether.
* lisp/gnus/nnmaildir.el (nnmaildir-request-article): Enable
multipart 8bit-content-transfer-encoded files to be displayed
correctly by reading as `raw-text' instead of having Emacs
(incorrectly) decode the files (bug#44307).
Copyright-paperwork-exempt: yes
* lisp/gnus/message.el (message-forward-ignored-headers): Clarify
doc string once again.
(message-forward-make-body-mime): Remove headers when not
encrypted (bug#45631).
(message-forward-make-body): Pass in correct values.
* lisp/gnus/gnus-art.el (gnus-mime-action-alist): Remove duplicated
"toggle display" entry and call the appropriate function for the "view
as charset" action (bug#45561).
* lisp/gnus/gnus-search.el (gnus-search-run-search): Imap servers need
to be opened (made into the "current server") before we manipulate the
nnimap-buffer.
(gnus-search-run-search): Sneakily fix regexp.
(gnus-search-indexed-parse-output): We need to pass the server name in
here, otherwise nnmaildir won't know how to make this the "current
server".
Give get-buffer-create an optional argument to inhibit buffer hooks
in internal or temporary buffers for efficiency (bug#34765).
* etc/NEWS: Announce new parameter of get-buffer-create and
generate-new-buffer, and that with-temp-buffer and with-temp-file
now inhibit buffer hooks.
* doc/lispref/buffers.texi (Buffer Names): Fix typo.
(Creating Buffers): Document new parameter of get-buffer-create and
generate-new-buffer.
(Buffer List, Killing Buffers): Document when buffer hooks are
inhibited.
(Current Buffer):
* doc/lispref/files.texi (Writing to Files): Document that
with-temp-buffer and with-temp-file inhibit buffer hooks.
* doc/lispref/internals.texi (Buffer Internals): Document
inhibit_buffer_hooks flag. Remove stale comment.
* doc/misc/gnus-faq.texi (FAQ 5-8):

* lisp/progmodes/flymake-proc.el
(flymake-proc--read-file-to-temp-buffer)
(flymake-proc--copy-buffer-to-temp-buffer): Simplify.
* lisp/subr.el (generate-new-buffer): Forward new optional argument
to inhibit buffer hooks to get-buffer-create.
(with-temp-file, with-temp-buffer, with-output-to-string):
* lisp/json.el (json-encode-string): Inhibit buffer hooks in buffer
used.
* src/buffer.c (run_buffer_list_update_hook): New helper function.
(Fget_buffer_create): Use it. Add optional argument to set
inhibit_buffer_hooks flag instead of comparing the buffer name to
Vcode_conversion_workbuf_name. All callers changed.
(Fmake_indirect_buffer, Frename_buffer, Fbury_buffer_internal)
(record_buffer): Use run_buffer_list_update_hook.
(Fkill_buffer): Document when buffer hooks are inhibited. Use
run_buffer_list_update_hook.
(init_buffer_once): Inhibit buffer hooks in Vprin1_to_string_buffer.
(Vkill_buffer_query_functions, Vbuffer_list_update_hook): Document
when hooks are inhibited.
* src/buffer.h (struct buffer): Update inhibit_buffer_hooks
commentary.
* src/coding.h (Vcode_conversion_workbuf_name):
* src/coding.c (Vcode_conversion_workbuf_name): Make static again
since it is no longer needed in src/buffer.c.
(code_conversion_restore, code_conversion_save, syms_of_coding):
Prefer boolean over integer constants.
* src/fileio.c (Finsert_file_contents): Inhibit buffer hooks in
" *code-converting-work*" buffer.
* src/window.c (Fselect_window): Fix grammar. Mention
window-selection-change-functions alongside buffer-list-update-hook.
* test/src/buffer-tests.el: Fix requires.
(buffer-tests-inhibit-buffer-hooks): New test.
* lisp/gnus/gnus-sum.el (gnus-summary-read-group-1): Move setting
gnus-pick-line-number from here (bug#45269)...
(gnus-summary-prepare): To here. This ensures that the number is
reset when regenerating the buffer, for instance when limiting it.
* lisp/gnus/gnus-registry.el (gnus-registry-register-all): If nil,
the registry won't automatically create new entries for all seen
messages. Defaults to t to preserve previous behavior.
(gnus-registry-handle-action): Don't automatically create entries; if
one doesn't exist, don't handle anything.
(gnus-registry-register-message-ids): Only register if this option is
t.
(gnus-registry-get-or-make-entry): Add optional no-create argument.
(gnus-registry-get-id-key): This "get" operation should only create an
entry if this option is t.
* doc/misc/gnus.texi: Documentation and news.
* lisp/gnus/gnus-win.el (gnus-buffer-configuration): Include
shell-command-buffer-name value rather than symbol in pipe
configuration. (Bug#39138, bug#45154)
One search may be applied to several servers: don't let one server's
error derail the whole process.
* lisp/gnus/gnus-search.el (gnus-search-config-error): Define new
error.
(gnus-search-run-search, gnus-search-server-to-engine): Raise this
specific error as appropriate.
(gnus-search-run-query): Catch this error and effectively demote it.
* lisp/gnus/nnimap.el (nnimap--split-download-body): New variable.
(nnimap-fetch-inbox): Use it in conjunction with
nnimap-split-download-body.
* lisp/gnus/spam.el: Don't load nnimap.el at compile time for a
dynamic variable.
(spam-setup-widening): Rather than unconditionally set user option
nnimap-split-download-body, set nnimap--split-download-body to a
unique non-nil value only if the variable was nil (bug#44981).
(spam-teardown-widening): New function that undoes this if
nnimap--split-download-body still holds the unique value.
(spam-unload-hook): Call spam-teardown-widening to revert any change
to the value of nnimap--split-download-body.
* lisp/gnus/nnimap.el (nnimap-split-download-body): And add an
obsolete alias for `nnimap-split-download-body-default'.
(nnimap-fetch-inbox): Check the value of the option, not the variable.
* doc/misc/gnus.texi (Client-Side IMAP Splitting): Move the primary
documentation of this option to this section.
* lisp/gnus/gnus-search.el (gnus-search-imap-handle-flag): This allows
"mark:A" to be translated into "ANSWERED" and "-mark:A" to be
translated into "UNANSWERED".
This behavior both better matches the previous nnir behavior, reducing
confusion for new users, and matches behavior when using parsed
queries.
* lisp/gnus/gnus-search.el (gnus-search-imap-search-keys): Make sure
this variable contains all known IMAP search keys.
(gnus-search-run-search): If the search query doesn't start with a
known search key, prepend "TEXT " to the query.
* doc/misc/gnus.texi (Summary Maneuvering): Document it.
* lisp/gnus/gnus-sum.el (gnus-paging-select-next): New variable.
(gnus-summary-prev-page, gnus-summary-next-page): Use it.
* lisp/gnus/gnus-search.el (gnus-search-indexed-parse-output): When
filtering for desired groups, accept any of [.\/] as potential segment
delimiters. Later on, filesystem path separators will be interpreted
as dots (".") when constructing group names. Also, make sure we use
`expand-file-name' on the prefix, and just use `string-remove-prefix'
to get rid of it.
So we aren't re-instantiating (and potentially configuring) them with
every search.
* lisp/gnus/gnus-search.el (gnus-search-engine-instance-alist): New
variable holding server->engine mapping.
(gnus-search-server-to-engine): See if we've already instantiated this
server. If so, return it. If not, instantiate it and save in the above
variable.
(gnus-search-shutdown): Shutdown function clearing the above alist.
* lisp/gnus/gnus-group.el (gnus-group-make-search-group,
gnus-group-read-ephemeral-search-group): If a search is initiated from
a topic line, make sure we get all the groups under that topic (and
under sub-topics).
