Uwe Schindler resolved LUCENE-2975. ----------------------------------- Resolution: Fixed Fix Version/s: 4.0 3.2 Assignee: Uwe Schindler Lucene Fields: [New, Patch Available] (was: [New]) Committed 3.1 revision: 1083239 Committed 3.x revision: 1083240 Committed trunk revision: 1083245 > hotspot bug in readvint gives wrong results > ------------------------------------------- > > Key: LUCENE-2975 > URL: https://issues.apache.org/jira/browse/LUCENE-2975 > Project: Lucene - Java > Issue Type: Bug > Affects Versions: 3.1 > Reporter: Uwe Schindler > Assignee: Uwe Schindler > Priority: Blocker > Fix For: 3.1, 3.2, 4.0 > > Attachments: LUCENE-2975.patch, LUCENE-2975.patch, LUCENE-2975.patch, > LUCENE-2975.patch, LUCENE-2975.patch, perf.png > > > When testing the 3.1-RC1 made by Yonik on the PANGAEA (www.pangaea.de) > productive system I figured out that suddenly on a large segment (about 5 > GiB) some stored fiels suddenly produce a strange deflate decompression > problem (CompressionTools) although the stored fields are no longer pre-3.0 > compressed. It seems that the header of the stored field is read incorrectly > at the buffer boundary in MultiMMapDir and then FieldsReader just incorrectly > detects a deflate-compressed field (CompressionTools). > The error occurs reproducible on CheckIndex with MMapDirectory, but not with > NIODir or SimpleDir. The FDT file of that segment is 2.6 GiB, on Solaris the > chunk size is Integer.MAX_VALUE, so we have 2 MultiMMap IndexInputs. > Robert and me have the index ready as a tar file, we will do tests on our > local machines and hopefully solve the bug, maybe introduced by Robert's > recent changes to MMap. -- This message is automatically generated by JIRA.
