Revision: miles@gnu.org--gnu-2004/emacs--cvs-trunk--0--patch-628
Merge from gnus--rel--5.10
Patches applied:
* miles@gnu.org--gnu-2004/gnus--rel--5.10--patch-55
Update from CVS
2004-10-19 Katsumi Yamaoka <yamaoka@jpl.org>
* lisp/gnus/gnus-sum.el (gnus-update-summary-mark-positions): Search for
dummy marks in the right way.
2004-10-18 Kevin Greiner <kgreiner@compsol.cc>
* lisp/gnus/nnagent.el (nnagent-request-type): Bind gnus-agent to nil to
avoid infinite recursion via gnus-get-function.
2004-10-18 Kevin Greiner <kgreiner@compsol.cc>
* lisp/gnus/gnus-agent.el (gnus-agent-synchronize-group-flags): When
necessary, pass full group name to gnus-request-set-marks.
(gnus-agent-synchronize-group-flags): Added support for sync'ing
tick marks.
(gnus-agent-synchronize-flags-server): Be silent when writing file.
2004-10-18 Kevin Greiner <kgreiner@compsol.cc>
* lisp/gnus/gnus-agent.el (gnus-agent-synchronize-group-flags): Replaced
gnus-request-update-info with explicit code to sync the in-memory
info read flags with the marks being sync'd to the backend.
2004-10-18 Kevin Greiner <kgreiner@compsol.cc>
* lisp/gnus/gnus-agent.el (gnus-agent-possibly-synchronize-flags): Ignore
servers that are offline. Avoids having gnus-agent-toggle-plugged
first ask if you want to open a server and then, even when you
responded with no, asking if you want to synchronize the server's
flags.
(gnus-agent-synchronize-flags-server): Rewrote read loop to handle
multi-line expressions.
(gnus-agent-synchronize-group-flags): New internal function.
Updates marks in memory (in the info structure) AND in the
backend.

deletion to remove entire duplicate line. Fixes merged article
number bug.
* lisp/gnus/gnus-util.el (gnus-remassoc): Fixed typo in documentation.
* lisp/gnus/nnagent.el (nnagent-request-set-mark): Use
gnus-agent-synchronize-group-flags, not backend's request-set-mark
method, to ensure that synchronization updates marks in the
backend and in the info (in memory) structure.
2004-10-18 Kevin Greiner <kgreiner@compsol.cc>
* lisp/gnus/gnus-agent.el (gnus-agent-synchronize-flags-server): Do nothing
unless plugged. Disable the agent so that an open failure causes
an error.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc> for Reiner Steib <Reiner.Steib@gmx.de>
* lisp/gnus/gnus-agent.el (gnus-agent-fetched-hook): Add :version.
(gnus-agent-go-online): Change :version.
(gnus-agent-expire-unagentized-dirs)
(gnus-agent-auto-agentize-methods): Add :version.
2004-10-18 Kevin Greiner <kgreiner@compsol.cc>
* lisp/gnus/legacy-gnus-agent.el (gnus-agent-convert-to-compressed-agentview-prompt):
New function. Used internally to only display 'gnus converting
files' message when actually necessary.
* lisp/gnus/gnus-sum.el (): Removed (require 'gnus-agent) as required
methods now autoloaded.
* lisp/gnus/gnus-int.el (gnus-request-move-article): Use
gnus-agent-unfetch-articles in place of gnus-agent-expire to
improve performance.
2004-10-18 Kevin Greiner <kgreiner@compsol.cc>
* lisp/gnus/gnus-agent.el (gnus-agent-cat-groups): rewrote avoiding defsetf
to avoid run-time CL dependencies.
(gnus-agent-unfetch-articles): New function.
(gnus-agent-fetch-headers): Use gnus-agent-braid-nov to validate
article numbers even when local .overview file is missing.
(gnus-agent-read-article-number): New function. Only accepts
27-bit article numbers.
(gnus-agent-copy-nov-line, gnus-agent-uncached-articles): Use
gnus-agent-read-article-number.
(gnus-agent-braid-nov): Rewrote to validate article numbers coming
from backend while recognizing that article numbers in .overview
must be valid.
* lisp/gnus/gnus-start.el (gnus-convert-old-newsrc): Changed message text as
some users confused by references to .newsrc when they only have a
.newsrc.eld file.
(gnus-convert-mark-converter-prompt,
gnus-convert-converter-needs-prompt): Fixed use of property list.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc> for Katsumi Yamaoka <yamaoka@jpl.org>
* lisp/gnus/gnus-agent.el (gnus-agent-restore-gcc): Use ^ and regexp-quote.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc> for Lars Magne Ingebrigtsen <larsi@gnus.org>
* lisp/gnus/gnus-start.el (gnus-get-unread-articles-in-group): Don't do
stuff for non-living groups.

* lisp/gnus/gnus-agent.el (gnus-agent-synchronize-flags): Default to nil.
(gnus-agent-regenerate-group): Using nil messages aren't valid.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc> for Lars Magne Ingebrigtsen <larsi@gnus.org>
* lisp/gnus/gnus-agent.el (gnus-agent-read-agentview): Inline
gnus-uncompress-range.
2004-10-18 Kevin Greiner <kgreiner@xpediantsolutions.com>
* lisp/gnus/legacy-gnus-agent.el
(gnus-agent-convert-to-compressed-agentview): Fixed typos with
help from Florian Weimer <fw@deneb.enyo.de>
* lisp/gnus/gnus-agent.el (gnus-agentize):
gnus-agent-send-mail-real-function no longer set to current value
of message-send-mail-function but rather a lambda that calls
message-send-mail-function. The change makes the agent real-time
responsive to user changes to message-send-mail-function.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc> for Reiner Steib <Reiner.Steib@gmx.de>
* lisp/gnus/gnus-start.el (gnus-get-unread-articles): Fix last commit.

gnus-group-real-name and gnus-find-method-for-group.
(gnus-agent-set-local): Delete stored entry if either min, or max,
are nil.
(gnus-agent-fetch-session): Reworded error/quit messages. On
quit, use gnus-agent-regenerate-group to record existance of any
articles fetched to disk before the quit occurred.
* lisp/gnus/gnus-int.el (gnus-request-delete-group): Use
gnus-cache-delete-group and gnus-agent-delete-group to keep the
local disk in sync with the server.

gnus-cache-rename-group and gnus-agent-rename-group to keep the
local disk in sync with the server.
* lisp/gnus/gnus-start.el (gnus-get-unread-articles): Cosmetic
simplification to logic.
* lisp/gnus/gnus-group.el (): (gnus-group-delete-group): No longer update
gnus-cache-active-altered as gnus-request-delete-group now keeps
the cache in sync.
(gnus-group-list-active): Let the agent store a server's active
list if currently plugged.
* lisp/gnus/gnus-util.el (gnus-rename-file): New function.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc> for Katsumi Yamaoka <yamaoka@jpl.org>
* lisp/gnus/gnus-agent.el (gnus-agent-regenerate-group): Activate the group
when the group's active is not available.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc> for Katsumi Yamaoka <yamaoka@jpl.org>

* lisp/gnus/gnus-start.el (gnus-convert-old-newsrc): Only write the
conversion message to newsrc-dribble when an actual conversion is
performed.

* lisp/gnus/gnus-agent.el (gnus-agent-read-local): Bind
nnheader-file-coding-system to gnus-agent-file-coding-system to
avoid the implicit assumption that they will always be equal.
(gnus-agent-save-local): Bind buffer-file-coding-system, not
coding-system-for-write, as the with-temp-file macro first prints
to a buffer then saves the buffer.
2004-10-18 Kevin Greiner <kgreiner@xpediantsolutions.com>
* lisp/gnus/legacy-gnus-agent.el (): New. Provides converters that are only
loaded when gnus-convert-old-newsrc needs to call them.
* lisp/gnus/gnus-agent.el (gnus-agent-read-agentview): Removed support for
old file versions.
(gnus-group-prepare-hook): Removed function that converted list
form of gnus-agent-expire-days to group properties.
* lisp/gnus/gnus-start.el (gnus-convert-old-newsrc): Registered new
converters to handle old agent file formats. Added logic for a
"backup before upgrading warning".
(gnus-convert-mark-converter-prompt): Developers can mark
functions as needing (default), or not needing,
gnus-convert-old-newsrc's "backup before upgrading warning".
(gnus-convert-converter-needs-prompt): Tests whether the user
should be protected from potentially irreversable changes by the
function.
2004-10-18 Kevin Greiner <kgreiner@xpediantsolutions.com>
* lisp/gnus/gnus-int.el (gnus-request-accept-article): Inform the agent that
articles are being added to a group.
(gnus-request-replace-article): Inform the agent that articles
need to be uncached as the cached contents are no longer valid.
* lisp/gnus/gnus-agent.el (gnus-agent-file-header-cache): Removed.
(gnus-agent-possibly-alter-active): Avoid null in numeric
comparison.
(gnus-agent-set-local): Refuse to save null in local object table.
(gnus-agent-regenerate-group): The REREAD parameter can now be a
list of articles that will be marked as unread.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc>
* lisp/gnus/gnus-range.el (gnus-sorted-range-intersection): Now accepts
single-interval range of the form (min . max). Previously the
range had to look like ((min . max)). Likewise, return
(min . max) rather than ((min . max)).
(gnus-range-map): Use gnus-range-normalize to accept
single-interval range.
* lisp/gnus/gnus-sum.el (gnus-summary-highlight-line): Articles stored in
the cache, but not the agent, now appear with their usual face.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc>

"nndraft:queue" along to gnus-draft-send. Use
gnus-agent-prompt-send-queue.
(gnus-draft-send): Rebind gnus-agent-queue-mail to nil when group
is "nndraft:queue". Suggested by Gaute Strokkenes
<gs234@srcf.ucam.org>
* lisp/gnus/gnus-group.el (gnus-group-catchup): Use new
gnus-sequence-of-unread-articles, not
gnus-list-of-unread-articles, to avoid exhausting memory with huge
numbers of articles. Use gnus-range-map to avoid having to
uncompress the unread list.
(gnus-group-archive-directory,
gnus-group-recent-archive-directory): Fixed invalid ange-ftp
reference.
* lisp/gnus/gnus-range.el (gnus-range-map): Iterate over list or sequence.
(gnus-sorted-range-intersection): Intersection of two ranges
without requiring that they first be uncompressed.
* lisp/gnus/gnus-start.el (gnus-activate-group): Unless blocked by the
caller, possibly expand the active range to include both cached
and agentized articles.
(gnus-convert-old-newsrc): Rewrote in anticipation of having
multiple version-dependent converters.
(gnus-groups-to-gnus-format): Replaced gnus-agent-save-groups with
gnus-agent-save-active.

excessively.

* lisp/gnus/gnus-start.el (gnus-convert-old-newsrc): Registered new
converters to handle old agent file formats. Added logic for a
"backup before upgrading warning".
(gnus-convert-mark-converter-prompt): Developers can mark
functions as needing (default), or not needing,
gnus-convert-old-newsrc's "backup before upgrading warning".
(gnus-convert-converter-needs-prompt): Tests whether the user
should be protected from potentially irreversable changes by the
function.
2004-10-18 Kevin Greiner <kgreiner@xpediantsolutions.com>
* lisp/gnus/gnus-int.el (gnus-request-accept-article): Inform the agent that
articles are being added to a group.
(gnus-request-replace-article): Inform the agent that articles
need to be uncached as the cached contents are no longer valid.
* lisp/gnus/gnus-agent.el (gnus-agent-file-header-cache): Removed.
(gnus-agent-possibly-alter-active): Avoid null in numeric
comparison.
(gnus-agent-set-local): Refuse to save null in local object table.
(gnus-agent-regenerate-group): The REREAD parameter can now be a
list of articles that will be marked as unread.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc>
* lisp/gnus/gnus-range.el (gnus-sorted-range-intersection): Now accepts
single-interval range of the form (min . max). Previously the
range had to look like ((min . max)). Likewise, return
(min . max) rather than ((min . max)).
(gnus-range-map): Use gnus-range-normalize to accept
single-interval range.
* lisp/gnus/gnus-sum.el (gnus-summary-highlight-line): Articles stored in
the cache, but not the agent, now appear with their usual face.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc>
* lisp/gnus/gnus-sum.el (gnus-adjust-marks): Now correctly handles a list of
marks consisting of a single range {for example, (3 . 5)} rather
than a list of a single range { ((3 . 5)) }.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc>
* lisp/gnus/gnus-sum.el (gnus-adjust-marks): Avoid splicing null INTO the
uncompressed list.
2004-10-18 Kevin Greiner <kevin.greiner@compsol.cc>
* lisp/gnus/gnus-draft.el (gnus-group-send-queue): Pass the group name
"nndraft:queue" along to gnus-draft-send. Use
gnus-agent-prompt-send-queue.
(gnus-draft-send): Rebind gnus-agent-queue-mail to nil when group
is "nndraft:queue". Suggested by Gaute Strokkenes
<gs234@srcf.ucam.org>
* lisp/gnus/gnus-group.el (gnus-group-catchup): Use new
gnus-sequence-of-unread-articles, not
gnus-list-of-unread-articles, to avoid exhausting memory with huge
numbers of articles. Use gnus-range-map to avoid having to
uncompress the unread list.
(gnus-group-archive-directory,
gnus-group-recent-archive-directory): Fixed invalid ange-ftp
reference.
* lisp/gnus/gnus-range.el (gnus-range-map): Iterate over list or sequence.
(gnus-sorted-range-intersection): Intersection of two ranges
without requiring that they first be uncompressed.
* lisp/gnus/gnus-start.el (gnus-activate-group): Unless blocked by the
caller, possibly expand the active range to include both cached
and agentized articles.
(gnus-convert-old-newsrc): Rewrote in anticipation of having
multiple version-dependent converters.
(gnus-groups-to-gnus-format): Replaced gnus-agent-save-groups with
gnus-agent-save-active.
(gnus-save-newsrc-file): Save dirty agent range limits.
* lisp/gnus/gnus-sum.el (gnus-select-newgroup): Replaced inline code with
gnus-agent-possibly-alter-active.
(gnus-adjust-marked-articles): Faster handling of simple lists
2004-10-18 David Edmondson <dme@dme.org>
* lisp/gnus/mm-view.el (mm-w3m-cid-retrieve-1): Don't use recursive call
excessively.
