This is fixed in 2.0b5 which I just put up on
The cause was, as predicted, that doxover() had problems with XOVER lines
which didn't contain an Xref: field. In addition, news.mozilla.org produces
truncated XOVER lines which do not conform to the specification if
there are too many References in the articles. I built a hack into
doxover() to find this as well and behave properly.
Further good news: filtering works again (it didn't because of a very
dumb error of mine, see ChangeLog); and fetchnews will be faster now
if you download groups with many "to-be-killed" articles in it
(because now fetchnews will *first* check if the article should be
killed; only if this is not the case it looks for the message-id on
the harddrive). I fetched 12 articles and killed 1796 (due to "maxage")
from news.mozilla.org in 17 seconds.
Problems that remain: many. The following is copied-and-pasted from the
announce of 2.0b3 and amended where necessary:
- The documentation is still incomplete. Most notably, the README
misses sections 4.1 and 4.2, and the TODO is partially in German.
- fetchnews may still sometimes coredump on fixxover() (Joerg?).
- The xover code contains bugs which are currently being discussed
on the list and may lead to loading of false XOVER info. .overview
files are written correctly.
- The AUTHINFO support for the nntpd is incomplete and needs fixing.
- Texpire currently doesn't seem to do any threading. Joerg has
promised to look into this :-)
- The timeout code for fetchnews sucks big time. As a result, fetchnews
doesn't handle timeouts properly or not at all.
- if HAVE_SNPRINTF and HAVE_VSNPRINTF are undefined, compiling vsnprintf.c
generates two warnings.
- if HAVE_STRDUP is undefined, strdup.c doesn't compile. It throws
around a lot of very odd error messages, and I don't know why.
- I did not yet incorporate Joerg's patch for moderated groups due
to lack of time.
- nntpd cannot report which host connected to it if compiled with IPV6.
The reason for that is that I have absolutely no documentation
- I have no idea why Leafnode-2.0b4 decided to truncate my groupinfo file
this night. It has not tried this again today. I'll tell you tomorrow
whether it will do it again this night :-)
If you get coredumps, it helps if you can tell me on which server that
happened. For example, to debug the coredump above it was very helpful
that I could reproduce it locally.
