autotest: Temporarily starting daemons

[address@hidden]

Hi,

I'm trying to temporarily fork off a daemon (BIND's named) within a  
testsuite. Yet the testsuite hangs despite having started the daemon.  
Below is an excerpt of the circumstances. Running testsuite -v shows  
that the hang occurs not as one would assume during the fork of the  
daemon but in the subsequent check for its pid. This occurs both when  
making the daemon startup a separate AT_CHECK item as well as when  
making it a simple shell statement. However, named starts properly  
and, since I'm not killing it for now, continues to run past SIGINT of  
the test suite .

I understand that things enclosed between AT_SETUP and AT_CLEANUP run  
within their own subshell hence my plan was to start named, do some  
tests and kill it within those two. Could it be that named is  
capturing stdout/stderr irretrievably away from autotest or is forking  
generally a problem?

Thanks,

-mat

And then either:

cd $TESTDIR/hierarchical && $NAMED_PROG -c authoritative.conf
AT_CHECK([test -f $TESTDIR/hierarchical/authoritative.pid], [0], [], [])
AT_CLEANUP

or:

AT_SETUP([Starting authoritative BIND])
AT_CHECK([cd $TESTDIR/hierarchical && $NAMED_PROG -c  
authoritative.conf], [0], [], [])
AT_CHECK([test -f $TESTDIR/hierarchical/authoritative.pid], [0], [], [])
AT_CLEANUP
