- * Introduction.
-
- This kit contains a drop-in replacement for nntp.el in GNUS 3.14.* and
- 3.15. It may work with other versions, but definitely not with GNUS2.
-
- This replacement is marginally faster at parsing nntp output in
- general, but the major improvement is it will use the nntp XOVER
- extension if available. With XOVER, entering a newsgroup is
- substantially faster: reading and parsing 600 headers takes about 3s
- on a Sun-4/20 (but threading is still quite slow).
-
- Without XOVER, this kit may not be worth it. But it should be easy to
- try it, and easy to back out from.
-
-
- * Installing.
-
- 1. Copy chat.el and nntp.el to your elisp directory. nntp.el is a
- direct replacement for the nntp.el that comes with GNUS. chat.el is
- an auxiliary module needed by nntp.el.
-
- 2. Byte-compile chat.el and nntp.el, in that order. It's best if you
- use Jamie Zawinski's byte compiler, which is better than the one in
- Emacs 18. This byte compiler is shipped with Emacs 19 and can also be
- found at the elisp archive: archive.cis.ohio-state.edu.
-
-
- * XOVER support.
-
- There are two types of news servers that support XOVER:
-
- 1. INN version 1.3 and later supports an overview database and XOVER
- directly.
-
- Note, there's some bug in INN 1.3 that causes the server to drop the
- connection after certain XOVER requests. If you keep getting "NNTP:
- connection closed" messages when talking to INN 1.3 server, then you
- probably have this bug. In this case, you can either upgrade the
- server to INN 1.4, or avoid using XOVER. I don't know of any other
- simple workarounds.
-
- 2. C News/nntpd. C News needs to be augmented with Geoff Collyer's
- nov.dist.tar.Z (available from world.std.com). nntpd needs to be
- augmented with the XOVER patch (included in this distribution), which
- should become "standard" with the next release of nntpd.
-
-
- * About Xrefs.
-
- GNUS relies on the Xref: header to mark crossposted articles
- correctly. By default, the overview database does not include Xref:
- information.
-
- If you do not have Xref: data, this nntp.el will try to adapt by
- grabbing the Xref: header when you retrieve an article. This works
- much of the time, but isn't perfect. In particular, kill files and
- catch-up will not mark crossposted articles correctly.
-
- A better idea is to include Xref: data in the overview database. For
- C news/nov.dist, you need to uncomment the line in mkov.c that says:
- /* putextfld("xref", hdrp->h_xref); */
- and then rebuild mkov.
-
- For INN, you just need to uncomment the line in /news/lib/overview.fmt
- that says:
- #Xref:full
