Description Adam Williamson 2018-08-13 15:56:03 UTC 
In the 20180812.n.0 Rawhide compose, the FreeIPA server test failed. Server deployment completes successfully, but when the test then runs 'ipa host-add client001.domain.local --password=monkeys --force' (to set up a kickstart client enrolment test), it fails:

https://openqa.fedoraproject.org/tests/265073#step/role_deploy_domain_controller/41

looking at the HTTP server logs, we see this:

as crys points out, that's not the most useful error message ever (why not give us a traceback, or at least a frickin' line number?!), but it's what we've got, so far.

This "sequence of byte string values expected" seems specific to python-wsgi: if you search it, all the results are from people doing something wrong with WSGI. Not sure how much that helps.

Comment 1 Adam Williamson 2018-08-13 18:39:14 UTC 
It seems that this did not happen in the 0813.n.0 compose tests. Not sure if something was specifically fixed, or if this is intermittent?
Comment 2 Adam Williamson 2018-08-13 18:55:27 UTC 
It looks like this was actually caused by #1615586 - this was just what that segfault caused to fail, when it happened at this specific moment. In other tests, the overall FreeIPA test process has failed at other points in the process, but the common factor is that segfault. In this particular test, the segfault happened during the same second this wsgi error was logged, so it seems pretty strongly likely that the segfault caused the wsgi error.
