Uwe Schindler resolved LUCENE-2087. ----------------------------------- Resolution: Fixed Committed revision: 882977 > Remove recursion in NumericRangeTermEnum > ---------------------------------------- > > Key: LUCENE-2087 > URL: https://issues.apache.org/jira/browse/LUCENE-2087 > Project: Lucene - Java > Issue Type: Improvement > Components: Search > Affects Versions: 2.9, 2.9.1, 3.0 > Reporter: Uwe Schindler > Assignee: Uwe Schindler > Priority: Minor > Fix For: 3.1 > > Attachments: LUCENE-2087.patch > > > The current FilteredTermEnum in NRQ uses setEnum() which itsself calls > next(). This may lead to a recursion that can overflow stack, if the index is > empty and a large range with low precStep is used. With 64 bit numbers and > precStep == 1 there may be 127 recursions, as each sub-range would hit no > term on empty index and the setEnum call would then call next() which itsself > calls setEnum again. This leads to recursion depth of 256. > Attached is a patch that converts to iterative approach. setEnum is now > unused and throws UOE (like endEnum()). -- 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: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
