Subject [jira] [Updated] (LUCENE-3037) TestFSTs.testRealTerms produces a corrupt index
Date Tue, 19 Apr 2011 13:04:05 GMT

Robert Muir updated LUCENE-3037:
--------------------------------

    Attachment: LUCENE-3037_test.patch

here's a much faster (fails in 2 seconds) test case. 

I noticed with this one, it fails with StandardPostingsReader, so I think the problem is general
to multi-level skipping.

The patch forces our random skip interval to be [2,10] instead of [2,64], thus causing us
to test higher skiplevels more than usual.

ant test-core -Dtestcase=TestLongPostings -Dtestmethod=testLongPostings -Dtests.seed=7951749419575219720:5894148324166575802
-Dtests.codec=MockRandom
