Dawid Weiss commented on SOLR-5914:
-----------------------------------
> sounds like he calling it quits for now though,
No, no man -- I just had to do some real work and called in for a break. I also
don't mean it has to be you in particular to fix those tests; like Uwe said,
there are just a bunch of them (perhaps more, if we take a different seed --
didn't check) so it's probably a realistic goal to fix these and merge back. If
you look at the diff from trunk there were many horrible, horrible temp
snippets I nuked. Perhaps I also introduced some regressions, another look from
a different person would be definitely good.
I'll get back to it when I can, obviously.

> 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\.\org.apache.solr.cloud.TestShortCircuitedRequests-1395693845226
> 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!
