Michael McCandless updated LUCENE-635:
--------------------------------------
Attachment: LUCENE-635-Aug3.patch
This patch contains the same source changes as my July 26 patch, but this one
is done "correctly" as the output of a single top-level "svn diff" command (ie,
I ran "svn add ..." locall for the new files). I also added an entry to
CHANGES.txt, and corrected newlines on one of the sources.
> [PATCH] Decouple locking implementation from Directory implementation

> This is a spinoff of http://issues.apache.org/jira/browse/LUCENE-305.
> I've opened this new issue to capture that it's wider scope than
> LUCENE-305.
> This is a patch originally created by Jeff Patterson (see above link)
> and then modified as described here:
> http://issues.apache.org/jira/browse/LUCENE-305#action_12418493
> with some small additional changes:
> * For each FSDirectory.getDirectory(), I made a corresponding
> version that also accepts a LockFactory instance. So, you can
> construct an FSDirectory with your own LockFactory.
> * Cascaded defaulting for FSDirectory's LockFactory implementation:
> if you pass in a LockFactory instance, it's used; else if
> setDisableLocks was called, we use NoLockFactory; else, if the
> system property "org.apache.lucene.store.FSDirectoryLockFactoryClass"
> is defined, we use that; finally, we'll use the original locking
> implementation (SimpleFSLockFactory).
> The gist is that all locking code has been moved out of *Directory and
> into subclasses of a new abstract LockFactory class. You can now set
> the LockFactory of a Directory to change how it does locking. For
> example, you can create an FSDirectory but set its locking to
> SingleInstanceLockFactory (if you know all writing/reading will take
> place a single JVM).
> The changes pass all unit tests (on Ubuntu Linux Sun Java 1.5 and
> Windows XP Sun Java 1.4), and I added another TestCase to test the
> LockFactory code.
> Note that LockFactory defaults are not changed: FSDirectory defaults
> to SimpleFSLockFactory and RAMDirectory defaults to
> SingleInstanceLockFactory.
> Next step (separate issue) is to create a LockFactory that uses the OS
> native locks (through java.nio).
