Description Adrian Likins 2013-06-21 16:32:54 UTC

Description of problem:

See https://bugzilla.redhat.com/show_bug.cgi?id=976855


When starting up, subman makes a call to it's candlepin server to determine the server versioning so it can log it (as well as checking for server status and capabilities).


Fixes:

Wait until we have to make a server /status call (ideally, just before the first needed api call) and update the server version info there.

Don't make this call solely to get server version. If we need it for /status info, collect it then, but don't do it for just the version. 

Make this call async, so client startup does not block on it. 

See the attachment to 976855 for a profile showing this.

commit ee59e0df48dd9702424fc21dc9ab4ecfbb1992a9

    976859: Only check server version if asked.
    
    976859 is about the server version check done by
    the cli being slow, which it is (at least for
    invocations that otherwise don't use the network)
    
    315d08e880 moved the check to use a thread so as
    to not block, but 1284120 was a bug in it.
    
    For simplicity, this commit removes the threading,
    but also removes the server version check from all
    cli sub commands except 'register' and 'version'
    since it was of limited utility in practice.
