Subject [jira] Commented: (LUCENE-1558) Make IndexReader/Searcher ctors readOnly=true by default
Date Sun, 04 Oct 2009 09:35:56 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12762009#action_12762009

Michael McCandless commented on LUCENE-1558:
--------------------------------------------

bq.  Do you want to put them back again?

I think we should?  Ie, "readOnly=true" is the natural default for creating an IndexReader?
 Seems silly to force people to specify true/false when they create an IndexReader.  But maybe
wait until we reach closure on the config/builder discussion on java-dev?

> Another "change the defaults" in 3.0.
> Right now you get a read/write reader from IndexReader.open and new IndexSearcher(...),
and reserving the right to write causes thread contention (on isDeleted).
> In 3.0 let's make readOnly reader the default, but still allow opening a read/write IndexReader.
