System: rn version 4.1
Bug #: 28
Priority: LOW
Subject: rn doesn't find new articles as quickly as it should on 4.2
Description:
Rn tries to discard the current buffer from the active file whenever
it wants to find the size of a newsgroup, but the discard isn't
successful most of the time on 4.2 because stdio buffers grew, and
fseeking forward 1024 bytes doesn't usually get out of the current
buffer.
Repeat-By:
If you find that you have to exit a newsgroup and re-enter to get
rn to see a new article, you have the problem. In particular, you
ought to be seeing your own followups without having to exit the
newsgroup.
Fix: From rn, say "| patch -d DIR", where DIR is your rn source directory.
Outside of rn, say "cd DIR; patch <thisarticle". If you don't have
the patch program, apply the following by hand, or get patch.
