-----------------------------------------
Summary: 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.
