Subject [jira] [Commented] (SOLR-2654) <lockType/> not used consistently in all places Directory objects are instantiated
Date Tue, 09 Aug 2011 06:28:27 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2654?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13081466#comment-13081466
] 

Mark Miller commented on SOLR-2654:
-----------------------------------

Okay, looks like i am close to having this figured out - I changed tactics to do the ref counting
in the dir factory, and then having the user release the directory. For whatever reason, this
made things easier to debug. I found an issue I had that was making the previous attempt difficult,
and also what looks like a nasty bug (more to come) that was compounding the issue. Still
a fair amount to try and do to finish this off as I want, but making progress.

> nipunb noted on the mailing list then when configuring solr to use an alternate <lockType/>
(ie: simple) the stats for the SolrIndexSearcher list NativeFSLockFactory being used by the
Directory.
> The problem seems to be that SolrIndexConfig is not consulted when constructing Directory
objects used for IndexReader (it's only used by SolrIndexWriter)
> I don't _think_ this is a problem in most cases since the IndexReaders should all be
readOnly in the core solr code) but plugins could attempt to use them in other ways.  In general
it seems like a really bad bug waiting to happen.
