group names starting with digits

group names starting with digits

[Uwe Geuder]

Our company internal newsgroup names start with numbers, like

   1.foo.bar
   2.more.stuff

Emacs 20.3's standard gnus (Gnus v5.5; nntp 5.0; nnvirtual 1.1; nnmh
1.0; nndraft 1.0) gets completely confused about this. nntp.el
interprets the group names as NNTP response codes, doesn't wait long
enough for the last responses and finally parses completely wrong
group status info. 

This was mentioned earlier on this list:

Having had a look at nntp.el I'd say it's in fact bad enough if the
group name starts with a digit.

Has anybody made a fix for that? It shouldn't be too difficult, but 
after 7 years without programming elisp I might not get it right on 
the first attempt... There seem to numerous places that need a change.

Yes, I've checked pgnus-0.82 and the problematic code is still 
unmodified.

Regards,

Uwe

AFAIK, these names are illegal.  Newfroup name parts start with alphabetic
characers.  Ie, foo1.bar and more2.stuff are legal, but foo.1 is not.

It's not invalid to have group names that start with numbers (I
think), but it's highly, highly discouraged to have group that have
components that are numeric-only, like something.42.other and the
like.  But Gnus should grok them, I think.

The problem is storage.  Most news servers (like INN) use an heirarchy of
directories for groups and numbered files for individual articles.  If a
group has a numerical name part, the server will get confused, treating
what should be a directory as an article.  You can lose entire heirarchies
that way.

Numerics should be avoided in group names, just on general principle.

What code is problematic?  Point, and I'll fix.  :-)
