Re: ClamAV(R) blog: ClamAV 0.102.0 Release Candidate is now available

That's related to something I'd suggested earlier.  I think it would be nice to fork into the background and accept clamdscan connections (but to block scanning) during the initial database load.  Of course, a part of why I like that idea is so that we don't have to put sleep()'s in some of our test harness code.  I suppose it's a bit of a poor excuse to make functional changes to make testing easier.  Others expressed concern that it shouldn't background or accept connections until everything is up.  

We could certainly check if the socket is available first just to fail early if needed, but not bind to it or accept connections until after the database is loaded.

    Hi there,
    
    This came about today when I accidentally started a clamd with the
    configuration file of a clamd instance which was already running:

    Oct  4 16:21:09 mail6 clamd[13990]: Not listening on any interfaces
    
    Note that clamd loaded all its databases, which took over four minutes,
    and only then decided that it couldn't listen on any interfaces!
    
    Perhaps it would be better to check for things which can be checked
    quickly *before* loading nine million signatures.
