Jon Meredith commented on CASSANDRA-15170: ------------------------------------------ Here's the latest - had all the updated branches passing on macOS and a container based on the CircleCI image. I need to make one more pass over it and would like to move the gossip and streaming shutdown from trunk to 2.2 and merge forward. 2.2 | [Branch|https://github.com/jonmeredith/cassandra/commits/in-jvm-dtest-fixes-v3-2.2] | [CircleCI|https://circleci.com/gh/jonmeredith/cassandra/tree/in-jvm-dtest-fixes-v3-2%2E2] 3.0 | [Branch|https://github.com/jonmeredith/cassandra/commits/in-jvm-dtest-fixes-v3-3.0] | [CircleCI|https://circleci.com/gh/jonmeredith/cassandra/tree/in-jvm-dtest-fixes-v3-3%2E0] 3.11 | [Branch|https://github.com/jonmeredith/cassandra/commits/in-jvm-dtest-fixes-v3-3.11] | [CircleCI|https://circleci.com/gh/jonmeredith/cassandra/tree/in-jvm-dtest-fixes-v3-3%2E11] trunk | [Branch|https://github.com/jonmeredith/cassandra/commits/in-jvm-dtest-fixes-v3-trunk] | [CircleCI|https://circleci.com/gh/jonmeredith/cassandra/tree/in-jvm-dtest-fixes-v3-trunk] > Reduce the time needed to release in-JVM dtest cluster resources after close > ---------------------------------------------------------------------------- > > Key: CASSANDRA-15170 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15170 > Project: Cassandra > Issue Type: Improvement > Components: Test/dtest > Reporter: Jon Meredith > Assignee: Jon Meredith > Priority: Normal > > There are a few issues that slow the in-JVM dtests from reclaiming metaspace > once the cluster is closed. > IsolatedExecutor issues the shutdown on a SingleExecutorThreadPool, sometimes > this thread was still running 10s after the dtest cluster was closed. > Instead, switch to a ThreadPoolExecutor with a core pool size of 0 so that > the thread executing the class loader close executes sooner. > If an OutboundTcpConnection is waiting to connect() and the endpoint is not > answering, it has to wait for a timeout before it exits. Instead it should > check the isShutdown flag and terminate early if shutdown has been requested. > In 3.0 and above, HintsCatalog.load uses java.nio.Files.list outside of a > try-with-resources construct and leaks a file handle for the directory. This > doesn't matter for normal usage, it leaks a file handle for each dtest > Instance created. > On trunk, Netty global event executor threads are still running and delay GC > for the instance class loader. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
