Subject: Make the agent eagerly cache articles
Date: Thu, 14 Apr 2011 21:16:07 -0300

Package: Emacs,Gnus
Version: 24.0.50

IIUC gnus-agent-cache only causes headers to be cached.  Not caching
full articles made a lot of sense a few years ago, but with current disk
sizes, most/many MUAs happily keep a full local copy of the remote IMAP
folders and Gnus should be able to do the same.

Downloading articles isn't so much about disk space as network
capacity.  But I agree with you that the Agent should probably download
the articles by default.

Does anybody mind me switching `gnus-agent-predicate' to `true' by
default?

I'm talking about caching.  I.e. keeping local copies after we've
downloaded them, so it shouldn't increase network traffic, only disk use.

Maybe that would be good, yes.  A better docstring would also be
welcome: I don't understand the current one.

Hm.  Caching?

Oh, I thought you were talking about the download categories (i.e., what
happens when you type `J s').

Let's see...  caching...  so if you're online (in an agentised group)
and select an article, you want the article to be saved in the Agent
directory?  That sounds eminently reasonable, and I thought that was
supposed to happen, but I can't find any code for doing that...  hm...
Nope.

Articles are entered into the (non-agent) cache if `gnus-use-cache' is
set to t, though.

This is now fixed in git Gnus.
