Hi Doug, Here is a list of lost bug fixes/improvements with v2.4.0
LUCENENET-183 LUCENENET-182 LUCENENET-175 LUCENENET-174 LUCENENET-170 LUCENENET-169 LUCENENET-168 LUCENENET-163 LUCENENET-160 LUCENENET-159 LUCENENET-106 DIGY -----Original Message----- From: Doug Sale [mailto:dougs...@gmail.com] Sent: Friday, July 31, 2009 7:06 PM To: lucene-net-dev@incubator.apache.org Subject: Lucene.Net 2.4.0 Regarding the 2.4.0 port: On Tuesday, I checked in the port that I completed earlier this year. We've been integrating it into a number of systems at MySpace (thanks to Bala Rangaraj and Michael Garski for catching and fixing a handful of bugs). The initial check-in lacks a few classes/features that exist in the Lucene Java 2.4.0 release. TODO ==== 1) Implement Lucene.Net.Store.NIOFSDirectory.cs (org.apache.lucene.store.NIOFSDirectory.java) This is a Java subclass of FSDirectory that allows multiple threads to read from a single file without blocking each other. Write behavior is inherited from FSDirectory. If anyone would like to take a stab at this, please be my guest. 2) File Descriptor syncing in FSDirectory.cs FSDirectory.Sync(string) is supposed to sync the underlying file descriptor, flushing all downstream buffers. I'm not sure how to accomplish this is C#, and this code needs to be reviewed/fixed/nuked. 3) Lucene.Net.Search.TimeLimitedCollector.cs I have implemented this class and I am currently working on the unit test. 4) Weak References I plan to work on these later today. Lucene.Net.Util.CloseableThreadLocal.cs - Lucene Java uses weak references - Lucene.Net is using 'regular' references Lucene.Net.Search.CachingSpanFilter.cs Lucene.Net.Search.CachingWrapperFilter.cs Lucene.Net.Search.FieldCacheImpl.cs - Lucene Java utilizes java.util.WeakHashMap - Lucene.Net is not using a data structure with weak references 5) Lucene.Net.Store.CheckSumIndex[Input|Output].cs These, I completed and checked in on Wednesday. They use, to the best of my knowledge, the same CRC32 algorithm as the java.util.zip classes (they have to, for index compatibility between Lucene.Net and Lucene Java.) I provided a new test, TestSupportClass.cs, to verify the results against a checksum generated in Java. Thanks, Doug
