------------------------------------------------
Summary: IOException unwrapping in CommitLogReader.
readCommitLogSegment misses exceptions in resource creation block
Key: CASSANDRA-13895
URL: https://issues.apache.org/jira/browse/CASSANDRA-13895
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Catalin Grigoroscuta
Priority: Minor
CommitLogReader. readCommitLogSegment is unwrapping IOExceptions wrapped as
RuntimeExceptions using a try-with-resource block.
However, the resource specification block, {{RandomAccessReader reader =
RandomAccessReader.open(file)}}, could also throw such an exception, which is
missed by the catch block and throws as a RuntimeException instead of an
IOException.
One such example that I've seen is:
- RandomAccessReader.open (called in try-with-resource resource specification
block initialization)
- ChannelProxy(File) constructor
- ChannelProxy.openChannel (wraps IOException as RuntimeException)
I don't know what the impact in Cassandra could be, I ran into this while
processing CDC/commit logs for synchronization with another system.
Was using Cassandra 3.11.0
