> Project: Apache Camel
> Issue Type: Bug
> Components: camel-hawtdb
> Affects Versions: 2.3.0
> Reporter: Hiram Chirino
> Assignee: Hiram Chirino
> Fix For: 2.4.0
>
>
> HawtDB 1.1 has been released. Change log at:
> http://github.com/chirino/hawtdb/blob/master/changelog.md
> We should upgrade to pick up the listed bug fixes:
> {quote}
> * Fixing BTree node next linking.. It was possible that a next link would
> not properly get set in some conditions during a node removal.
> * You can add get callbacks when a commit gets flushed to disk.
> * Changed the way the journal was handling callback based write completed
> notifications. They are now delivered in batch form to a single
> JournalListener. This reduces thread contention and increases throughput.
> * Moved the built in predicate implementations into a Predicates class.
> * Added close method to the Transaction interface. Implementation now
> asserts it is no longer used after a close.
> * Making the appender's max write batch size configurable.
> * Revamped how Update and DefferedUpdates track shadow pages. A little
> easier to follow now. - changed the interface to PagedAccessor so that
> instead of removing the linked pages, it just needs to report what the linked
> pages are.
> * Got rid of the WriteKey wrapper class, updated logging.
> * Better looking printStrucuture BTree method
> * Added a few Logging classes to reduce the number of places we need to
> update if in case we decided to switch logging APIs.
> * Fixing free page allocation bug when using deferred updates.
> * Javadoc improvements
> * Expose a config property to control the read cache size.
> * Reworked how snapshot tracking was being done. Fixes errors that
> occurred during heavy concurrent access.
> * Added a non-blocking flush method to the TxPageFile
> * Read cache was not getting updated when a update batch was performed.
> Cached entries that were updated and flushed to disk continued returning
> stale data.
> * Fixed an recovery edge cases
> * Don't start the thread from the thread factory. that causes illegal
> state exceptions
> * Fixed journal bug where getting next location could return a the
> current location
> * Renamed EncoderDecoder to PagedAccessor
> * The util.buffer package has moved into it's own project at
> http://github.com/chirino/hawtbuf
> * Fixes #4 : Errors occur when you re-open an empty data file.
> * Extracted a SortedIndex interface from the Index interface to non
> sorted indexes having to deal with that leaky abstraction.
> * added a free() method to the Paged for symmetry with the alloc() method.
> * Improved website documentation
