`^ ... RET' server mode adds groups to *Group*?

`^ ... RET' server mode adds groups to *Group*?

[Karl Kleinpaste]

Go into the server buffer with `^'.
Wander down to an appropriate NNTP server, e.g. my primary, as
{nntp:news} (opened)
Now RET.

XEmacs cogitates at great length, presumably sorting the group list.
At the end of this effort, I am placed in my *Group* buffer, with
_all_ my server's groups added to *Group* at level 9 "killed" status.

Doubleplusungood.  I thought `^ RET' should give me a server-specific
group listing for transient or ephemeral access to groups?

Same here with GNU Emacs 21.0.95.1 (i586-pc-linux-gnu, X toolkit) of
2001-01-10 on g.wolfram.com.  Didn't that start happening with ognus?

Still having an older version of 5.8.8 available I see no such delay
but an immediate listing for...I guess what Karl calls:
"transient or ephemeral access"

It shows the same groups that `L' would show only limited to that
server, and in a buffer called "*Gnus Browse Server*", all at killed
status.

Found it.  It's deliberate.  From the ChangeLog:

2000-10-30 00:49:33  ShengHuo ZHU  <zsh@cs.rochester.edu>

	* gnus-srvr.el (gnus-server-browse-in-group-buffer): New variable.
	(gnus-server-read-server-in-server-buffer): New function.
	(gnus-browse-foreign-server): Browse in group buffer.

Setting to nil gets the old behavior.

I think having this variable defaulting to t is suboptimal.  And it's
much, much slower (due to having to go through the gyrations of adding
groups to *Group*) than browsing a server in its own server buffer.

The advantage is that you can access groups in group buffer, but you
cannot in server browse buffer.

I don't understand why it's an advantage.

Having a server-browsing buffer is for the specific purpose of looking
over what a particular server has to offer, and allowing the user to
ephemerally look into any of them, or do a general subscription pick
out of the complete list.

How does tacking this monstrous mass of mostly crud into *Group* do
anything useful for me?  On my PII-450, it took well over 2 minutes of
internal hackery for Gnus to do the shovel-groups-into-*Group*-as-
killed (because managing *Group* is comparatively convoluted), whereas
going for the original buffer-browsing-server-by-itself popped up in
all of perhaps 15 seconds.  My active file is about 600K.

I just don't see what new capability this is supposed to provide.

Have things already been changed?  Todays cvs shows different
behavior.

`^' in `server' buffer and <RET> on nntp server, immediately moves me to
group buffer displaying all groups I have, including unsubscribed ones
under that server.

I don't see the massive work Karl describes.  What I see is nothing
more than `L' listing but limited to nntp server groups.

A <spc> on nntp server seems to give the old behavior in tact.

What is the intent, again?

Nothing has been changed for three months.

If the server had thousands of groups, you would see the massive work.

It is because all of those groups are in gnus-killed-list.

Yes. For the sake of speed.

> What is the intent, again?

First, it is in the wish list.  Second, you can do much more things in
the group buffer than in the Gnus browse server buffer.

I'm still confused as to what it does.  Is it different than pressing
`A A' in group buffer? 

That server has some 29,000+ groups.

Pressing `A A' in Group gives me. 
some 29,000 lines  1300K of active file

Pressing <RET> on that nntp server in server_buffer gives me some 40 lines

But it displays almost instantly.  And `A k' in group
shows some 15,000 lines

So it is different than `A A'?

There differences are that `A A'
    1. does not list groups on foreign servers;
    2. sorts groups by name and list them in flat mode;
    3. does not show the levels of groups.

Do you use it in unplugged mode?

In unplugged mode, `^ RET' only list groups in saved active file and
killed-list, so it is nothing more than `L' listing.

How many groups are from the nntp server?

Yes.

Ahhh theres the rub... I was unplugged.  I see how it works now  and
the extra functionality is nice.  Esp. since we still have <spc> for
the old behavior.

Regexp matching is another good reason to move it to group buffer.

[...]

Yes indeed.  Another difference that isn't so apparent is that `A A'
works the same plugged or unplugged.  (long as a link is up, of course)

Whereas  the new `<RET> on server' offers different functionality
plugged and unplugged.  More options, always a plus.

One thing I noticed that may be a small bug is that under certain
conditions after pressing <spc> on a server.  When leaving that buffer
with `q'.  It can cause a major cpu drain while emacs pulls down all
available cpu and does nothing (not visibly any way).

I haven't been able to repoduce this reliably but it happened three
times (not in sequence) while I've been experimenting with this new
functionality.

Right. `A A' works as if Gnus were unagentized.

Maybe a prefix argument for gnus-server-read-server-in-server-buffer.

I guess Emacs was cleaning up garbage. Lots of symbols and cons are
used to list the groups.

It is an experimental feature in oGnus.  Only unknown or killed groups
are listed at level 9, and others groups are listed at the end of the
buffer if you use topic mode.  You may type `^ SPC' to list groups in
the old way, or (setq gnus-server-browse-in-group-buffer nil) to
disable the feature.

You can access killed groups. At least, I did it.
