1. What are the [ ] good for? I don't believe they belong there. Check
the PCRE documentation, and you can test your regular expressions
with pcregrep:
# simulate a posting's incomplete header:
echo 'Newsgroups: some.binaries.i.do.not.want' >try
# check - if it matches, you'll get a copy of the Newsgroups: line
# if it doesn't match, no output:
pcregrep '^Newsgroups:.*[ ]binaries$' try
only_groups_pcre may be a more efficient approach to this goal - but
watch out, you'll need rather complex regular expressions with
lookbehind assertions and negation. The archives of the mailing list
have some samples.
2. leafnode will download the header for these postings to decide if it
wants the body of such postings, for Newsgroups and Content-Type
headers are not cached in the overview data usually (and if they
were, leafnode would not currently use such information).
