Subject [jira] Commented: (LUCENE-2730) intermittent deadlock in TestAtomicUpdate,TestIndexWriterExceptions
Date Sun, 31 Oct 2010 13:23:23 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12926704#action_12926704

Michael McCandless commented on LUCENE-2730:
--------------------------------------------

bq. In my opinion we should remove the stupid synchronized in TermsHash completely (also trunk
and 3.x, I removed at least the compact()-sync). This class needs no sync.

We have to be somewhat careful w/ this.

Eg in 2.9.x/3.0.x some of the sync is needed because IW calls freeRAM "freely", ie, while
other threads are indexing.  IW still calls freeRAM in 3.x/4.0, but it's a no-op there since
we don't recycle RAM as aggressively anymore.  So likely we could remove sync from TermsHash
on 3.x/trunk, but let's do that another day...
