Markus Jelsma updated SOLR-10048: --------------------------------- Attachment: DistributedPagedQueryComponentTest.java > Distributed result set paging sometimes yields incorrect results > ---------------------------------------------------------------- > > Key: SOLR-10048 > URL: https://issues.apache.org/jira/browse/SOLR-10048 > Project: Solr > Issue Type: Bug > Security Level: Public(Default Security Level. Issues are Public) > Components: SearchComponents - other > Affects Versions: 6.4 > Reporter: Markus Jelsma > Priority: Critical > Fix For: 6.4.1, master (7.0) > > Attachments: DistributedPagedQueryComponentTest.java > > > This bug appeared in 6.4 and i spotted it yesterday when i upgraded a my > project. It has, amongst others,an extension of QueryComponent, its unit test > failed, but never in any predictable way and always in another spot. > The test is very straightforward, it indexes a bunch of silly documents and > then executes a series of getAll() queries. An array of ids is collected and > stored for comparison. Then, the same query is executed again but it pages > through the entire result set. > It then compares ids, the id at position N must be the same as id NUM_PAGE * > PAGE_SIZE + M (where M is the position of the result in the paged set). The > comparison sometimes failes. > I'll attach the test for 6.4 shortly. If it passes, just try it again (or > increase maxDocs). It can pass over ten times in a row, but it can also fail > ten times in a row. > You should see this if it fails, but probably with different values for > expected and actual. Below was a few minutes ago, now i can't seem to > reproduce it anymore. > {code} > [junit4] FAILURE 25.1s | > DistributedPagedQueryComponentTest.testTheCrazyPager <<< > [junit4] > Throwable #1: java.lang.AssertionError: ids misaligned > expected:<406> but was:<811> > [junit4] > at > __randomizedtesting.SeedInfo.seed([97A7F02D1E4ACF75:7493130F03129E6D]:0) > [junit4] > at > org.apache.solr.handler.component.DistributedPagedQueryComponentTest.testTheCrazyPager(DistributedPagedQueryComponentTest.java:83) > [junit4] > at > org.apache.solr.BaseDistributedSearchTestCase$ShardsRepeatRule$ShardsFixedStatement.callStatement(BaseDistributedSearchTestCase.java:992) > [junit4] > at > org.apache.solr.BaseDistributedSearchTestCase$ShardsRepeatRule$ShardsStatement.evaluate(BaseDistributedSearchTestCase.java:967) > [junit4] > at java.lang.Thread.run(Thread.java:745) > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
