Paulo Motta commented on CASSANDRA-17267:
-----------------------------------------
In the [previous test
run|https://ci-cassandra.apache.org/view/patches/job/Cassandra-devbranch/1422/]
{{org.apache.cassandra.index.sasi.SASIIndexTest.testSASIComponentsAddedToSnapshot}}
was getting stuck when running within the suite (worked when executed
individually).
I tracked down the reason to the {{ReadExecutionController}} not being closed
properly on other tests, causing operations to block indefinitely on the
{{{}OpOrder{}}}. Fixed [on this
commit|https://github.com/apache/cassandra/commit/77f688e75ff403875755f34dc31ab75401bcaa3d]
on all branches.
I created CASSANDRA-17400 to add a checker to verify resources are being
properly closed to avoid stuck tests in the future.

> Snapshot true size is miscalculated
> -----------------------------------

> Key: CASSANDRA-17267
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17267
> Project: Cassandra
> Issue Type: Bug
> Components: Local/Snapshots
> Reporter: Paulo Motta
> Assignee: Paulo Motta
> Priority: Normal
>
> As far as I understand, the snapshot "size on disk" is the total size of the
> snapshot, while the "true size" is the (size_on_disk - size_of_live_sstables).
> I created a snapshot on a 3.11 node without traffic and I expected the "true
> size" to be 0KB since the original sstables were still present, but this
> didn't seem to be the case:
> {noformat}
> $ nodetool listsnapshots
> Snapshot Details:
> Snapshot name Keyspace name Column family name True size Size on disk
> test ks1 tbl1 4.86 KiB 5.69 KiB
> Total TrueDiskSpaceUsed: 4.86 KiB
> {noformat}
