Subject Re: Some questions about recent patch delivery to the trunk
Date Sat, 20 Dec 2008 06:13:40 GMT

I'll let Digy respond to the FSDirectory modifications, as IIRC they are

However, the TestStressIndexing2 mods are mine.  There are fairly extensive
comments here:  To make a long story
short, the Java test works in spite of itself.  I can comment more fully, if
necessary, but I'll have to review the changes to be more specific.
