Cobbler doesn't run post-install triggers (#530 )

Hello all, I'm trying to figure out what's going on with https://fedorahosted.org/cobbler/ticket/530. This defect was originally reported (almost exactly 11 months ago) before 2.0.2, but 2.0.3.1 still suffers from the problem. As written, cobbler will *never* successfully call shell-style install/post triggers. Because subprocess_call() is called with logger=None, all the attribute references on logger fail. The calling chain: remote.run_install_triggers() calls utils.run_triggers() and does not provide the logger= keyword argument. There's a fix suggested in the ticket, but that just patches the problem. This seems to be the right fix, to cobbler/remote.py: --- remote.py 2010-10-28 21:46:28.000000000 -0400 +++ remote.py.new 2010-10-28 21:46:18.000000000 -0400 @@ -1205,7 +1205,7 @@ # time if reinstalling all of a cluster all at once. # we can do that at "cobbler check" time. - utils.run_triggers(self.api, None, "/var/lib/cobbler/triggers/install/%s/*" % mode, additional=[objtype,name,ip]) + utils.run_triggers(self.api, None, "/var/lib/cobbler/triggers/install/%s/*" % mode, additional=[objtype,name,ip], logger=self.logger)
