wildmat expressions in storage.conf

Hi -

I am referring to Jeffrey's posting <dq9ipf$lis$1...@puck.litech.org>
earlier this year where he recommended a newsgroup line in storage.conf
like:

| newsgroups: !*

I wonder if I missed a new development because man storage.conf tells me
regarding the newsgroup line that:

| ``!'' cannot be used, however.

What I want to achieve is the following (INN 2.4.2 at Debian Linux):

| method cnfs {
| newsgroups: de.*,!de.UNWANTED
| class: 1
| options: DE
| }
|
| method cnfs {
| newsgroups: *
| class: 2
| options: REST
| }

Before screwing my running server I'd like to ask if that will work?

Or will a "newsgroup: de.*,@de.UNWANTED" do the trick? I do have to
admit that I do not understand what is meant by "Poison wildmat
expressions ..." in storage.conf, especially if that will work in the
scenario outlined above.

Thanks,
Michael

I'd say no.

According to the docs, yes, with the caveat below.

Well, the poison wildmat is different from the negation in the case of a
crossposting. This means, in this case, that the article will not match
the storage clause if _any_ group in the newsgroups line matches. A
simple exclusion (when it's useable) mean that it doesn't match if _all_
the groups are unwanted.

Lets assume three different newsgroups header scenarios with a
"newsgroup: de.*,@de.UNWANTED" clause in storage.conf:

1. Newsgroups: de.wanted
2. Newsgroups: de.wanted,de.UNWANTED
3. Newsgroups: de.UNWANTED

Does that poison wildmat approach mean that only articles with headers
like in 1. will match the storage clause and those in 2. and 3. won't?

Michael

Thanks. I set up my storage clause as outlined above and it works the
way both of you anticipated (checked with showtoken).
