Joshua McKenzie commented on CASSANDRA-7927:
--------------------------------------------

Another updated pushed to branch 
[here|https://github.com/josh-mckenzie/cassandra/compare/7927];

While working on CASSANDRA-7579 I noticed that the _die unit test was failing 
on linux (for entirely different reasons than the Windows failure). Digging 
into it a bit shows that the unit test it was based on, 
testCommitFailurePolicy_stop(), didn't actually do what it was intended to do. 
StorageService isn't initialized by SchemaLoader so the assertions to check on 
_stop test always passed. Also, changing a directory to write-only doesn't 
change the contents to being write-only so flushes would keep working even if 
the StorageService had been started.

I've opened the interface on CommitLog.handleCommitError as public, marked it 
VisibleForTesting, and updated those 2 unit tests to check the logic 
specifically dealing with how our CommitLog system deals with throwables during 
stop and die policy settings.  Tests pass on both Windows and linux now.

> We got a disk read error on 1.2.13 that didn't trigger the disk failure 
> policy, and I'm trying to hunt down why, but in doing so, I saw that there is 
> no disk_failure_policy option for just killing the daemon.
> If we ever get a corrupt sstable, we want to replace the node anyway, because 
> some aws instance store disks just go bad.
> I want to use the JVMStabilityInspector from CASSANDRA-7507 to kill so that 
> remains standard, so I will base my patch on CASSANDRA-7507.
