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?
> Make IndexReader/Searcher ctors readOnly=true by default

> Key: LUCENE-1558
> URL: https://issues.apache.org/jira/browse/LUCENE-1558
> Project: Lucene - Java
> Issue Type: Improvement
> Affects Versions: 2.4.1
> Reporter: Michael McCandless
> Assignee: Michael McCandless
> Fix For: 3.0
>
>
> 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.
