If i use mock clean, does it break the data of koji ?

2010/4/1 Eric Zhong <ericiszhongwenjia@gmail.com>
I forgot to mention I use koji  instead of use mock directly!
This morning i want to start httpd and kojid ,  but ...

[eric@wenjia ~]$ sudo service httpd restart
stop httpd:                                               [OK]
starting httpd:httpd: apr_sockaddr_info_get() failed for wenjia.zhong
httpd: Could not reliably determine the server's fully qualified domain name, using for ServerName

[eric@wenjia conf]$ sudo service kojid start
starting kojid:Traceback (most recent call last):
  File "/usr/sbin/kojid", line 3450, in <module>
  File "/usr/lib/python2.6/site-packages/koji/__init__.py", line 1458, in ssl_login
    sinfo = self.callMethod('sslLogin', proxyuser)
  File "/usr/lib/python2.6/site-packages/koji/__init__.py", line 1503, in callMethod
    return self._callMethod(name, args, opts)
  File "/usr/lib/python2.6/site-packages/koji/__init__.py", line 1548, in _callMethod
    raise err
xmlrpclib.Fault: <Fault 1: "<class 'socket.gaierror'>: [Errno -2] Name or service not known">


when i set  ServerName = (my LAN IP ) , the httpd can be started successfull.
but the kojid return  the same info.

Very strangely ! I think some thing Wrong in koji !!!
Is it crash ?
If i reinstall koji ,the data in DB will be delete?  Import the srpm and rpm will spend a lot of time.
Please give some advise!

For a number of chroot operations (e.g. building), mock uses an
unprivileged user it creates in the chroot. By default, the uid/gid for
this unprivileged user is chosen based on the user running mock (it
looks at env data from sudo/consolehelper to determine the real user).

So, the builddir in the chroot is going to be owned by that unprivileged
user. If you run mock as a /different/ user later and attempt to reuse
the same buildroot, then you will get the errors like the ones you are

Short answer: different mock users cannot share chroots.

Easy fix: run mock clean to clear the old junk out of the buildroot.
