Quassia Wishes: Decoupling

Quassia Wishes: Decoupling

[Jost Krieger]

As Larsi is going out hacking Quassia (going in perhaps?),
I'd like to take out one of my favorite nags:

Decoupling of mail acquisition, mail storage, and posting.

Gnus used to be a news reader, as everybody knows :-)

News are put in the right place by the news system, and posting on
most machines is just done by nntp. Fine!

When adding mail, the picture gets more complicated.

In the old days, mail arrived in a nice file you could use movemail
on, and then you filtered it into the correct boxes. But nowadays,
mail arrives in the funniest ways, like prefiltered by procmail, or
laid out in a Maildir by qmail, or a few of them at the same time.

Also, there are more and more storage possibilities, nnml (nice and
fast), nnfolder (works nicely with compression) and so on. And then
there are those mails that can be only read with Netscape (fee!), hack
what you like.

So, what I would like to have, is an acquisition method associated
with each (mail storage) server, and for symmetry, a posting method,
too.

In the same area, I still dream about a mail filtering mechanism that
filters into different servers. 

Hitting "g" would walk the active mail acquisition methods, not the
mail storage methods like now. Respooling could be manual like now, or
go through the global mail-filter. To make that upward compatible
would mean an additional alist to pick out the server, I think.

Talking about filtering: From time to time, I would like to filter by
body contents (I know it's slow, but it would be prefiltered by from
or to). Any chance ?

Concerning compressions - it would be nice with compression support in
nnml. It would be very easy - just enable the compression extension (I
use crypt++, but I know there is a better one) and save the messages
as 1.gz, 2.gz or whatever. I tried manually compressing the mails, but
Gnus wouldn't find the compressed file. This is really high on my wish
list!

nnml supports compression.  Load `jka-compr' and just gzip the message
files.

As I said I already tried doing it. I have a (require 'jka-compr) in
my emacs, and I tried gzipping all the messages in an unimportant
group and all I get when I tried to view them is:

	No such article (may have expired or been canceled)

I tried without loading crypt++ (which I have used until now) this
time as I thought it might cause the problem, but didn't make a
difference. Loading .gz files etc does however work as expected. Do
you or anyone else have any idea why this doesn't work for me? :-(

I can't explain this.  It works without any problems for me.

When I tried to compress my groups it didn't work properly for me
either until I decompressed my active file (SOUP) and my .overview
file (nnml).

Is there a way to compress the messages in the groups recursively
without touching files like these?

Use find, xargs and gz with appropriate parameters.

find /dir/with/groups -name '*' -not -name 'active' -not -name '.overview' -exec gzip {} \;

(Untested, but should work.)

This works, thanks.

Actually whatever I did (uncompressed active file, *.IDX files) I
can't get SOUP to work with compressed files. Nnml works with
uncompressed active and .overview files.

Am I supposed to compress 23 to 23.gz or 23??

I also tried compressing and moving it to 23, and then all I got was
junk (ie the compressed file).

"23.gz".

Yup.  This is on the todo list.

Posting methods for mail backends?  Why?

To even further blur the line between mail, and news, naturally!

There shall be only one! (Och Aye!)
