J s and "g" when plugged dont do the same thing for me. "J s" does
something, but "plugged" groups dont get a new article count. "g" does
get the new article count. What does, in the docs,
"Fetch all articles and headers that are eligible for fetching."
mean? I assumed all articles which pass the category predicate.
I have a category "fun" with a predicate of "true". I am assuming this
means fetch all articles. The groups in question are added to this
category. Is that correct?
Or another way of asking, what are the conditions that mean J s and g
DONT do the same thing when plugged?

As I understand it:
g => query servers for info about any new articles that have
arrived. For 'mail-like' backends this may end up retrieving mail, for
nntp/nnimap it just updates article counts.
J s => download articles based on currently available headers according
to configured category predicates.
Informally: g means 'do I have anything new to read', and J s is 'download
stuff'.

Am I the only one who is getting errors on "J a" in the Group buffer?
Whenever I do it, I get the below:
Signaling: (void-variable function)
gnus-group-iterate(nil #<compiled-function (from "gnus-agent.elc") (group) "...(40)" [gnus-group-category group c delete groups] 4>)
#<compiled-function (from "gnus-agent.elc") (category arg) "...(42)" [category gnus-category-alist nil groups c cat gnus-group-iterate arg #<compiled-function (from "gnus-agent.elc") ... "...(40)" ... 4> gnus-category-write] 3 ("/home/simmonmt/gnus/lisp/gnus-agent.elc" . 8889) (list (intern ...) current-prefix-arg)>(default nil)
call-interactively(gnus-agent-add-group)
I tried byte-compiling the 0.8 source with 20.2 and 20.3b22 and tried
running both sets with both 20.2 and 20.3b22. I kept getting the
above.
There also seems to be some disagreement with the 0.8 patch as posted
and the 0.7 tarball on ftp.gnus.org. Nothing failed outright, but I
got several patches that were applied offset.

Yup. Fix in Quassia Gnus v0.9.

OK, I found out what was happening in the above, but it still breaks.
The cause of the above was:
(defun gnus-group-iterate (arg gnus-group-iterate-function)
[....] ______________/
(save-excursion /
(funcall function group))))))
(Hopefully you're looking a this in a fixed font =) )
gnus-group-iterate was declaring g-g-i-f but not using it. I replaced
function with g-g-i-f (see attachment) and gnus-group-iterate function
began to work again. It looks like the change crept in in the
qgnus-0.0-0.1 patch.
Once that's fixed, however, another problem pops up. The function
lambda'd up to be passed to gnus-group-iterate has (push group groups)
at the end. This would be OK, except for the fact that
gnus-group-iterate depends on groups emptying out at some point so it
can exit. If you try to gnus-agent-add-group a group that has not
previously been assigned[1], group gets passes down to the lambda'd
function, processed, and then pushed right back on groups. This
ensures that gnus-group-iterate will never exit. I tried to figure
out what the lambda'd function is trying to do, but I gave up.
Matt
Footnotes:
[1] I don't know about other cases - I've just checked g-a-a-g on a
group that has not previously been assigned. I'd check more, but
I'm trying to get this in before Lars goes to sleep. =)

I've now redefined that function to use gensymmed variables.
