Uwe Schindler resolved LUCENE-2716. ----------------------------------- Resolution: Fixed Commit standard BitSet variant in revision: 1026190 (OpenBitSet is 64bit and set/get of single bits is ineffective on 32bit machines, no need for bulk transformations) > Improve automaton's MinimizeOperations.minimizeHopcroft() to not create so > many objects > --------------------------------------------------------------------------------------- > > Key: LUCENE-2716 > URL: https://issues.apache.org/jira/browse/LUCENE-2716 > Project: Lucene - Java > Issue Type: Improvement > Affects Versions: 4.0 > Reporter: Uwe Schindler > Assignee: Uwe Schindler > Priority: Minor > Fix For: 4.0 > > Attachments: LUCENE-2716-2(OpenBitSet).patch, LUCENE-2716-2.patch, > LUCENE-2716.patch, LUCENE-2716.patch > > > MinimizeOperations.minimizeHopcroft() creates a lot of objects because of > strange arrays and useless ArrayLists with fixed length. E.g. it created > List<List<List<>>>. This patch minimizes this and makes the whole method much > more GC friendler by using simple arrays or avoiding empty LinkedLists at all > (inside reverse array). > minimize() is called very very often, especially in tests (MockAnalyzer). > A test for the method is prepared by Robert, we found a bug somewhere else in > automaton, so this is pending until his issue and fix arrives. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
