[jira] [Updated] (CASSANDRA-7712) temporary files need to be cleaned by unit tests

["Michael Shuler (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-7712?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Shuler updated CASSANDRA-7712:
--------------------------------------
    Attachment: 7712_workaround.txt

Attached 7712_workaround.txt patch to set a {{tmp.dir}} property and use that as a {{jvmarg}} in testlist.  Tested this with and without passing in the option with no problems - the jvm also created my custom tmp.dir for me.  This workaround provides us the ability to set the temporary data dir within our git workspace, and since we are using {{git clean -xdf}} at the beginning of every unit test run, this data will no longer accumulate.

> There are many unit test temporary files left behind after test runs. In the case of CI servers, I have seen >70,000 files accumulate in /tmp over a period of time. Each unit test should make an effort to remove its temporary files when the test is completed.
> My current unit test cleanup block:
> {noformat}
> # clean up after unit tests..
> rm -rf  /tmp/140*-0 /tmp/CFWith* /tmp/Counter1* /tmp/DescriptorTest* /tmp/Keyspace1* \
>         /tmp/KeyStreamingTransferTestSpace* /tmp/SSTableExportTest* /tmp/SSTableImportTest* \
