[leafnode-list] RELIABILITY ANNOUNCEMENT: leafnode 2.0b*

*** RELIABILITY ANNOUNCEMENT ***

Warning: all leafnode 2.0 alpha/beta versions that have been released on
March 12, 2000 or later up to and including 2.0b8 have a serious bug in
their dopost function in nntpd which handles receiving client's POSTs.

Here's the offending change from the log:

|120300: dopost(): articles are now immediately sorted into the spool.
|        This is achieved by fork()ing. nntpd ignores SIGCHLD therefore
|        (in main()).
|        One problem is that now fetchnews and the nntpd cannot be
|        run at the same time (?).

The trouble is that leafnode no longer detects posting
failures. leafnode replies with 240 to the client's POST command
although the actual acticle may have been lost for whatever
reason. Thus, articles may disappear without notice to the client. 

As these articles cannot be recovered from other servers, this is a
serious bug. There is no known workaround at this moment. 

leafnode 1.9.18 and -ma4* are not affected by this bug.
