[Exist-commits] eXist-1.0/src/org/exist/xquery LocationStep.java,1.80,1.81

[Wolfgang M. M. <wol...@us...>]

Update of /cvsroot/exist/eXist-1.0/src/org/exist/xquery
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv8648/src/org/exist/xquery

Modified Files:
	LocationStep.java 
Log Message:
Fixed a memory leak introduced in 11/2005: normally, eXist should not cache more than the most recent 256 XQueries. Due to the bug, references to old queries were still held in memory though they were removed from the cache. If many different queries are sent to the db, memory consumption will keep growing slow but steadily.
