Uwe Schindler created SOLR-5914:
-----------------------------------
Summary: Almost all Solr tests no longer cleanup their temp dirs
on Windows
Key: SOLR-5914
URL: https://issues.apache.org/jira/browse/SOLR-5914
Project: Solr
Issue Type: Bug
Components: Tests
Affects Versions: 4.8
Reporter: Uwe Schindler
Priority: Critical
Fix For: 4.8
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 no 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!
