Robert Stupp commented on CASSANDRA-8308:
-----------------------------------------
Some more information on this (using {{DatabaseDescriptorTest}} as an example):
# test methods {{testCFMetaDataSerialization}} +
{{testKSMetaDataSerialization}} run fine
# test method {{testTransKsMigration}} calls
{{SchemaLoader.cleanupAndLeaveDirs}}, which calls
{{CommitLog.instance.resetUnsafe()}}
# {{CommitLog.instance.resetUnsafe()}} calls
{{CommitLogSegmentManager.resetUnsafe}}, which waits until
{{segmentManagementTasks}} is empty
# there is one task (guess its the one from
{{CommitLogSegmentManager.wakeManager}} via {{advanceAllocatingFrom}}) in
{{segmentManagementTasks}}
# but {{segmentManagementTasks}} cannot become empty, because
{{COMMIT-LOG-ALLOCATOR}} is not running
# result is an infinite loop ; the test hangs and times out
Removing the first {{CommitLog.instance.resetUnsafe();}} in
{{SchemaLoader.cleanupAndLeaveDirs}} fixes {{ant test}} - but I don't know what
this means for Windows.
