Subject [jira] [Commented] (SOLR-5914) Almost all Solr tests no longer cleanup their temp dirs on Windows
Date Fri, 28 Mar 2014 01:23:15 GMT


Mark Miller commented on SOLR-5914:

Okay - good stuff I think.

If you guys have ideas for further improvements or spot issues, I'm happy to turn your thoughts
into code. Or just jump right in.

>          Issue Type: Bug
>          Components: Tests
>    Affects Versions: 4.8
>            Reporter: Uwe Schindler

> Recently the Windows Jenkins Build server has the problem of all-the time running out
of disk space. This machine runs 2 workspaces (4.x and trunk) and has initially 8 Gigabytes
of free SSD disk space.
> Because of the recently all-the time failing tests, the test framework does not forcefully
clean up the "J0" working folders after running tests. This leads to the fact, that the workspace
is filled with tons of Solr Home dirs. I tried this on my local machine:
> - run ant test
> - go to build/.../test/J0 and watch folders appearing: Almost every test no longer cleans
up after shutting down, leaving a million of files there. This is approx 3 to 4 Gigabytes!!!
> In Lucene the folders are correctly removed. This has happened recently, so i think we
have some code like ([~erickerickson] !!!):
> {{new Properties().load(new FileInputStream(...))}} that does not close the files. Because
of this, the test's afterClass cannot clean up folders anymore. If you look in the test log,
you see messages like "{{!!!! WARNING: best effort to remove C:\Users\JenkinsSlave\workspace\Lucene-Solr-4.x-Windows\solr\build\solr-core\test\J0\.\
FAILED !!!!!}}" all the time.
> So if anybody committed some changes that might not close files correctly, please fix!
Otherwise I have to disable testing on windows - and I will no longer run solr, tests, too:
My local computer also uses gigabytes of temp space after running tests!
