Stefan Podkowinski commented on CASSANDRA-14059:
------------------------------------------------
Sounds reasonable. I'd also suggest to add another character after the test
method name, to make it easier to recognize where the actual message starts.

> Root logging formatter broken in dtests

> Key: CASSANDRA-14059
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14059
> Project: Cassandra
> Issue Type: Bug
> Components: Testing
> Reporter: Joel Knighton
> Assignee: Joel Knighton
> Priority: Minor
>
> Since the ccm dependency in dtest was bumped to {{3.1.0}} in
> {{7cc06a086f89ed76499837558ff263d84337acba}}, when dtests are run with
> --nologcapture, errors of the following form are printed:
> {code}
> Traceback (most recent call last):
> File "/usr/lib64/python2.7/logging/__init__.py", line 861, in emit
> msg = self.format(record)
> File "/usr/lib64/python2.7/logging/__init__.py", line 734, in format
> return fmt.format(record)
> File "/usr/lib64/python2.7/logging/__init__.py", line 469, in format
> s = self._fmt % record.__dict__
> KeyError: 'current_test'
> Logged from file dtest.py, line 485
> {code}
> This is because CCM no longer installs a basic root logger configuration,
> which is probably a more correct behavior than what it did prior to this
> change. Now, dtest installs its own basic root logger configuration which
> writes to 'dtest.log' using the formatter {{'%(asctime)s,%(msecs)d %(name)s
> %(current_test)s %(levelname)s %(message)s'}}. This means that anything
> logging a message must provide the current_test key in its extras map. The
> dtest {{debug}} and {{warning}} functions do this, but logging from
> dependencies doesn't, producing these {{KeyError}} s.
