Shai Erera updated LUCENE-3761:
-------------------------------
Attachment: LUCENE-3761.patch
Updated patch:
- ThingyManager renamed to ReferenceManager
- Declared 'current' volatile (thanks Simon!)
- Added two tests to TestSM. While they could be under a TestReferenceManager
new class, I didn't think that creating another class + a ReferenceManager
extension is worth it.
- Added a CHANGES entry under back-compat (following maybeReopen to
maybeRefresh).
If nobody objects, I'd like to rename maybeRefresh to just refresh, and commit
it. Otherwise, I'll commit what I have.
I've decided to deal with the SearcherTaxoManager in a different issue.

> I'd like to generalize SearcherManager to a class which can manage instances
> of a certain type of interfaces. The reason is that today SearcherManager
> knows how to handle IndexSearcher instances. I have a SearcherManager which
> manages a pair of IndexSearcher and TaxonomyReader pair.
> Recently, few concurrency bugs were fixed in SearcherManager, and I realized
> that I need to apply them to my version as well. Which led me to think why
> can't we have an SM version which is generic enough so that both my version
> and Lucene's can benefit from?
> The way I see SearcherManager, it can be divided into two parts: (1) the part
> that manages the logic of acquire/release/maybeReopen (i.e., ensureOpen,
> protect from concurrency stuff etc.), and (2) the part which handles
> IndexSearcher, or my SearcherTaxoPair. I'm thinking that if we'll have an
> interface with incRef/decRef/tryIncRef/maybeRefresh, we can make
> SearcherManager a generic class which handles this interface.
> I will post a patch with the initial idea, and we can continue from there.
