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.
   (gnus-agent-check-overview-buffer): Fixed range of
   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.

2004-10-18  Kevin Greiner  <kevin.greiner@compsol.cc> for Lars Magne Ingebrigtsen  <larsi@gnus.org>

   * 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.

2004-10-18  Kevin Greiner  <kgreiner@xpediantsolutions.com>

   * lisp/gnus/gnus-cache.el (gnus-cache-rename-group): New function.
   (gnus-cache-delete-group): New function.

   * lisp/gnus/gnus-agent.el (gnus-agent-rename-group): New function.
   (gnus-agent-delete-group): New function.
   (gnus-agent-save-group-info): Use gnus-command-method when
   `method' parameter is nil.  Don't write nil entries into the
   active file.
   (gnus-agent-get-group-info): New function.
   (gnus-agent-get-local): Added optional parameters to avoid calling
   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-request-rename-group): Use
   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-agent.el (gnus-agent-read-agentview): Add a missing arg to
   error.

2004-10-18  Kevin Greiner <kevin.greiner@compsol.cc>

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

2004-10-18  Kevin Greiner <kevin.greiner@compsol.cc>

   * 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>

   * 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.
