* gnus.el (gnus-summary-high-uncached-face,

	* gnus.el (gnus-summary-high-uncached-face,
	gnus-summary-normal-uncached-face, gnus-summary-low-uncached-face)
	New faces.

	* gnus-agent.el (gnus-agent-downloaded-article-face): REMOVED.  I
	added this on 2002-11-23 but it just wasn't working out as
	intended.  The idea isn't entirely dead, three new faces
	gnus-summary-*-uncached-face are being added to gnus.el to provide
	the basis for an improved implementation.
	(gnus-agent-read-servers): Undo the change made on 2002-11-23. The
	proper file to open is lib/servers.
	(gnus-summary-set-agent-mark): Expanded documentation.  Unmarking
	(i.e. removing the article from gnus-newsgroup-downloadable) will
	now restore the article's default mark rather than simply setting
	no mark.
	(gnus-agent-get-undownloaded-list): Corrected documentation.
	Added code to set new summary local variable,
	gnus-newsgroup-agentized.  Reworked impl so that it doesn't create
	a temporary list.  No longer sets gnus-newsgroup-downloadable.
	(gnus-agent-summary-fetch-group): Keep gnus-newsgroup-undownloaded
	up to date.  Call new gnus-summary-update-download-mark to keep
	summary buffer up-to-date.
	(gnus-agent-fetch-selected-article): Keep
	gnus-newsgroup-undownloaded up to date.
	(gnus-agent-fetch-articles): Return list of articles that were
	successfully fetched.
	(gnus-agent-check-overview-buffer): No more thingatpt.
	(gnus-agent-expire): No longer deletes NOV entries of unread
	articles.
	(gnus-agent-unread-articles): New function.
	(gnus-agent-regenerate-group): The article number must be
	terminated by a tab character.  Added more messages to report
	repairs.  Inhibit quits while writing changes so it is now safe
	have to quit regeneration.  Renamed gnus-tmp-downloaded back to
	downloaded to 1) resolve the unbound references and 2) avoid
	confusing this list with the gnus-tmp-downloaded in gnus-sum.el

	* gnus-art.el (gnus-article-prepare): The agent
	downloaded/undownloaded mark is no longer stored as the article's
	mark.

	* gnus-salt.el (gnus-tree-highlight-node): Added uncached as
	gnus-summary-highlight may use it.  Added downloaded as
	gnus-summary-highlight was using it.

	* gnus-sum.el (gnus-undownloaded-mark): Changed from ?@ to ?- as
	the download mark now follows Kai's +/- convention.
	(gnus-downloaded-mark): Added ?+ mark.
	(gnus-summary-highlight): Added rules to select
	gnus-summary-high-uncached-face,
	gnus-summary-normal-uncached-face, and
	gnus-summary-low-uncached-face.  Removed the
	gnus-agent-downloaded-article-face.
	(gnus-summary-line-format-alist): Implemented the download flag
	format (?O) as named in the manual.  This implementation displays
	either gnus-undownloaded-mark, gnus-downloaded-mark, or
	gnus-no-mark.
	(gnus-newsgroup-agentized): New local variable that identifies
	which groups are agentized.  While the agent is now on by default,
	you don't have to agentize every server that you use.
	(gnus-update-summary-mark-positions): Completed support for the
	download type of mark.
	(gnus-summary-insert-line): Added undownloaded to the parameters.
	(gnus-summary-prepare-threads): Set gnus-tmp-downloaded for
	reference by the gnus-summary-line-format-spec.

	* nntp.el (nntp-with-open-group): This macro handles dropped or
	broken connections by opening a new connection and repeating the
	failed command.
	(nntp-retrieve-headers-with-xover): Some NNTP servers respond to
	XOVER commands preceeding the active articles with the nov entry
	of the first available article.  When gnus connected to such a
	server, the unexpected nov entry would result in duplicate lines
	in the agent's overview file.  This patch fixes the duplicate
	lines problem and improves performance by skipping over all
	articles IDs that preceed the first nov entry in the server's
	reply.

2002-12-11  Katsumi Yamaoka  <yamaoka@jpl.org>

	* gnus-sum.el (gnus-tmp-downloaded): New internal variable.
	(gnus-summary-highlight): Use it instead of `downloaded'.
	(gnus-summary-highlight-line): Ditto.

	* gnus-agent.el (gnus-agent-regenerate-group): Ditto.

2002-12-11  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* gnus.el (gnus-variable-list): Add gnus-agent-covered-methods.

	* gnus-agent.el (gnus-agent-check-overview-buffer): Remove debug
	calls.

	* gnus-sum.el (gnus-summary-highlight-line): Don't set the
	downloaded variable if we're in an uncovered group.

	* gnus-agent.el (gnus-agent-downloaded-article-face): Change the
	font to soemthing less noticeable.
	(gnus-agent-group-covered-p): New function.
