Michael Neale commented on JCR-863:
-----------------------------------
I agree with Marcel. This is getting really nasty if we want to support from
1.4 through 1.6 (Java) in a non ugly fashion. Its also very hard to test.
Perhaps the better solution is to make upgrading to Lucene 2.1 a priority, so
this code (which is lucene specific anyway) can be retired and this JIRA
closed.
> Patch to use FileLock for locking instead of empty file
> -------------------------------------------------------
>
> Key: JCR-863
> URL: https://issues.apache.org/jira/browse/JCR-863
> Project: Jackrabbit
> Issue Type: Improvement
> Components: query
> Reporter: Michael Neale
> Fix For: 1.4
>
> Attachments: FSDirectory.patch, JCR-863.patch
>
>
> The FSDirectory uses File.createNewFile to effectively lock a directory (in
> makeLock), yet the Java Spec says explcitly not to use it for this purpose,
> and instead use FileLock from nio.
> The attached patch shows how this is/could be done (change is internal to the
> makeLock method only, and functionally equivalent, the same tests apply).
