> Handle repeat open bound from SRP in read repair
> ------------------------------------------------
>
> Key: CASSANDRA-14330
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14330
> Project: Cassandra
> Issue Type: Bug
> Reporter: Aleksey Yeschenko
> Assignee: Aleksey Yeschenko
> Priority: Major
> Fix For: 4.0, 3.0.17, 3.11.3
>
>
> If there is an open range tombstone in an iterator, a short read protection
> request for it will include a repeat open bound. Currently, {{DataResolver}}
> doesn't expect this, and will raise an assertion, timing out the request:
> {code}
> java.lang.AssertionError: Error merging RTs on test.test: merged=null,
> versions=[Marker EXCL_START_BOUND(0)@0, null], sources={[/127.0.0.1,
> /127.0.0.2]}, responses:
> /127.0.0.1 => [test.test] key=0
> partition_deletion=deletedAt=-9223372036854775808, localDeletion=2147483647
> columns=[[] | []]
> Row[info=[ts=1] ]: ck=0 | ,
> /127.0.0.2 => [test.test] key=0
> partition_deletion=deletedAt=-9223372036854775808, localDeletion=2147483647
> columns=[[] | []]
> Row[info=[ts=-9223372036854775808] del=deletedAt=1,
> localDeletion=1521572669 ]: ck=0 |
> Row[info=[ts=1] ]: ck=1 |
> {code}
> As this is a completely normal/common scenario, we should allow for this, and
> relax the assertion.
> Additionally, the linked branch makes the re-trhowing {{AssertionError}} more
> detailed and more correct: the responses are now printed out in the correct
> order, respecting {{isReversed}}, the command causing the assertion is now
> logged, as is {{isReversed}} itself, and local deletion times for RTs.
