Compressing nnfolders..

Compressing nnfolders..

[Andy Eskilsson]

I have had some trouble with nnfolders, the reason to this trouble is
that I wanted compressed (through jka-compr) nnfolders to archive
memorizeable mail, and sgnus doesn't seem to do what I want it to do.

I seem to remember some discussion in this group before without
achieving any greater success, is there any work done to add the
ability to compress folders done? Some nncompress server or :-)

nnfolder uses the `raw' version of `find-file-noselect', which means
that it explicitly bypasses any of the find-file hook.  This was done
to avoid some terrible things that could happen, although I can't
remember exaclty what right now.  

Perhaps the raw version also bypasses the jka-compr things?

- From jka-aux.el:

;;;I have been distributing a package called jka-compr, which adds file
;;;compression to the low-level I/O functions in emacs.  Beginning with
;;;version 19.23, jka-compr became part of the standard lisp library.
;;;However, some eatures were taken out because they might not be
;;;considered desirable by all users.  Specifically, the 19.23 version of
;;;jka-compr will not search for a file called "foo.gz" if you do a
;;;find-file on "foo."  If you were fond of some of the features that are
;;;not present in the 19.23 version of jka-compr, you can use the
;;;following package (cryptically named jka-aux.el), which implements all
;;;those features.

All of the transparancies are in jka-aux, so you'll need to get that, too.
Hmmm... ohio-state is not letting me retrieve the LISPDIR file so I cannot
provide a pointer at this time.

You may or may not need to edit nnfolder.el; I suspect you will as some
edits are necessary in nnml.el (which I use) to make things like expire and
move work.  Any regular expression that points to a file name will need to
be edited to include your compression extension(s).  nnml.el is easy; I use
a simple script to do it for me:

  #!/bin/sh
  if test -f x-easymenu.el; then
    mv x-easymenu.el easymenu.el
  fi
  cp nnml.el nnml.el.orig
  cat nnml.el.orig | sed 's/\[0-9\]+/\[0-9\]+\\\\(\\\\.gz\\\\)?/g' > nnml.el

nnfolder.el may or may not be more cumbersome.

With jka-aux and jka-compr, compressed nnml digests now work fine out
of the box, at least with sgnus 0.38.

See <URL:http://www.fuentez.com/ding/> for a nnml digestifyer.

Warning jka-aux doesn't work with emacs 19.30 (I think the
incompability started around 19.28), the problem is that emacs tries
to find the loadup.el where emacs where compiled when using jka-aux.

I have reported this to the jka-aux author, he didn't have time to
check it, but he have heard about it.

It was something like nnfolders starting in cc-mode if they ended with
.cc.

| Perhaps the raw version also bypasses the jka-compr things?

Probably.....

Is there any possibility of doing some kind of compress-backend?

Ah, right.

There should be a way to use the jka-compr thingies.

jka-compr needs two things to make that happen:

1: jka-aux, which does not work in GNU Emacs 19.29/19.30.  Big problem,
   here, may or may not be resolved soon.  I would expect not as the
   autoload problems are still in jka-compr (autoload had a number of
   new forms added that are not accounted for in jka-compr).

2: Minor hackery in the backend .el files to expand the regular
   expressions used in buffers filled with the output of 'ls', to
   include a regular expression built out of jka-aux-extensions.
   Normally this is a simple list, '(".gz" ".Z")', should not be too
   difficult to turn into a regexp.  This is key, as the
   jka-compr/jka-aux functions will not operate inside buffers.

I have been using jka-compr/jka-aux in this fashion, with gzipped nnml
files, since... I forget how long :).

nnml does this as of September 0.27.  You should be able to gzip all
articles in nnml directories.  It has been only lightly tested,
though.
