I added a MySQL Disk Cache to JCS that extends the base JDBC Disk Cache.
The MySQL child has two new features. It can optimize on a schedule and balk.
The optimization schedule is a simple list of time in hh:mm:ss format.
The optimizer knows how to detect optimization failures and will try to
repair the table is the optimization fails.
It also logs the table status after optimization and how long it took to perform the optimization.
It can also be configured to balk during optimizations.
If you are running a JCS server cluster, it can be configured such that nodes will try to get from each other.
If the mysql disk cache balks, the primary will to try and fetch data from the failover. If the primary and failover are scheduled to optimize a few minute apart, then there should be no client impact.
I added a new pool access class and a table status object that is used to keep track of what processes might be working on a particular table.
I also changed the get to use toString rather than assume that the key is a string.

I fixed bug in sorted preferential array remove method.
It was generating error log messages from an array index out of bounds exception.
The new call to system arraycopy didn't work. I reverted it to the old manual copy.
I made a test that exposed the bug and verified the fix.
I increased the JCS temp build version and added an entry to the changes.xml

Finshed refactoring tcp lateral to use its own attributes, factory and manager.
I added allowGet, allowPut, issueRemoveOnPut, and filterRemoveByHashCode attributes
for TCP lateral, as discussed on the user list. I Added unit test for all new features.
I will add documentation on the new features later.
I still need to get the jgroups factory in order after the lateral refactoring.

Added shutdown observer framework.
Changed listener thread to a daemon.
Made executor on listener use a daemon setting thread factory.
1.2.6.7 was compiled under jdk 1.4. The new jgroups jar forces a 1.4 compilation.
I will move jgroups to the 1.4 extension build later so we can continue with 1.3.

Properties are loaded using the current thread's classloader by default.
When a config file is not found a descriptive error message is printed to the logs.
Made an interface for the cache manager to improve testability.
Auxiliaries are assigned a cache manager and the lateral TCP has a settable source id, so it can be tested.
Increased JGroups version to 2.2.8. It works again. The old JGroups didn't work for unknown reasons.
Cleaned up some javadocs.
Improved info level logging for TCP lateral.
Added configuration properties xdocs for TCP lateral, indexed disk, and memory cache.
Created concurrent tests for TCP lateral to verify correct region behavior.
Made BDBJE work with new auxiliary changes.
UDP discovery no longer activates if the lateral type isn't TCP.
Reduced lateral get timeout to 1 second, rather than 10. We still need to disable gets when a timeout occurs.

Added system properties override functionality to the configure stage.
You can set system properties that will be put into the cache properties prior to configuration.
Added a simple test for the feature.
Removed soem unused interfaces. There is inconsistency in the way interfaces are named. . . .
Changed auxiliary cache interface to use the cache factory. Many auxiliary listeners were
getting the factory by its get instance method. This made it
almost impossible to unit test them. I'm in the process of converting them all
to use the passed in cache manager. This will allow us to mock
out the manager and the composite cache and create tests for the auxiliaries.
This is a work in progress. The getCache method in the manager need to return an interface.

Added 2 new features to the TCP Lateral cache, some test files, and some unit tests.
New features:
1. Can send but not receive using the TCP lateral cache
By default you do both.
jcs.auxiliary.LTCP.attributes.Receive=false
This turns off receiving. If you just want to broadcast invalidations or puts this is useful.
Not all nodes need to receive. A data producer might not want to get messages.
This is very useful.
2. Configurationless TCP lateral cache
You can configure the TCP lateral to use UDP discovery.
Lateral caches will broadcast to a multicast address and port, letting
all listeners know where they are. One startup each lateral will request a broadcast from the others.
Broadcasts occur every 30 seconds. (to be made configurable)
Regions that don't receive don't broadcast anythign but requests.
When a lateral receives a discovery message it will try to add the lateral to the nowait facade for the
region. If it already exists nothing happens. If a region is not configured to send laterally, nothing happens,
since it doesn't have a no wait.
This allows you to have the same configuration on every machine.
Here is a sample config section:
jcs.auxiliary.LTCP=org.apache.jcs.auxiliary.lateral.LateralCacheFactory
jcs.auxiliary.LTCP.attributes=org.apache.jcs.auxiliary.lateral.LateralCacheAttributes
jcs.auxiliary.LTCP.attributes.TransmissionTypeName=TCP
#you can put something here or not
#jcs.auxiliary.LTCP.attributes.TcpServers=
jcs.auxiliary.LTCP.attributes.TcpListenerPort=1118
jcs.auxiliary.LTCP.attributes.PutOnlyMode=true
jcs.auxiliary.LTCP.attributes.UdpDiscoveryAddr=228.5.6.8
jcs.auxiliary.LTCP.attributes.UdpDiscoveryPort=6780
jcs.auxiliary.LTCP.attributes.UdpDiscoveryEnabled=true
jcs.auxiliary.LTCP.attributes.Receive=true
I'll add documentation later.

1. Fixed remote clustering (or server chaining) and failover.
I've tested with up to 3 remote servers.
You can chain remote servers. Basically, gets can be distributed.
Since gets are the most common operation, this will help a system scale.
Also you can set servers to failover. This allows you to have a hot standby.
2. Cleaned up javadocs all over the place. There is still more to do.

Fixed a bug that caused remote push to fail.
The event queues have an isAlive and an isWorking status. Originally isAlive meant that it hadn't died. No isAlive means are there any threads that are running. isWorking used to mean that there were threads working; now it means that the queue is in working order. This terminology isn't clear and lead to a bug. I will come up with new names.
The remote server used to check to see if a queue was alive before trying to send an update to a local. When we made the queues shutdown from inactivity, they started setting the isAlive to false. The remote server would then think they were bad and not try to add events. I now made the remote server check to see if the queue is working.
updated to bug fix version 1.2.1

Optional, configurable thread pools can be set for all auxiliaries. By default
the single queue is used. (Will document later.)
Shrinkers for all regions now share one thread and are executed by a Doug Lea
Clock Daemon.
The disk cache now has more configuration options exposed. You can set the purgatory size,
recycle bin size, etc. Alos, you can set a bound on the purgatory. This solves the possibility
or an ever growing purgatory with a bounded queue.
Uped version to 1.2-dev to mark the changes.
Updated some documentation. I need to rebuild the site. I published the new
disk cache config page already.
The disk cache options are described on the web site.
jcs.auxiliary.DC.attributes.MaxPurgatorySize=10000
jcs.auxiliary.DC.attributes.MaxKeySize=10000
jcs.auxiliary.DC.attributes.MaxRecycleBinSize=5000
jcs.auxiliary.DC.attributes.OptimizeAtRemoveCount=300000

Got rid of the JCSComponent based on stratum's component stuff, and removed
the dependency on stratum.
Since turbine has decided to go with avalon instead of creating our own
component stuff, stratum will be disolved. I do not think it would be a
good idea to release with a dependency on it, hopefully an avalon component
can be in the next release.

Reintroducing the Servlet interface to the cache. I rewrote it using velocity
which makes the code a little cleaner. I still would like to add a detail page
for viewing the items in the cache and removing one (or perhaps more than one).
Seems like a decent start.

Added another unit test that pounds the SAME region with 3 different threads,
rather than different regions.
This quickly showed a couple of synchronization problems in memory cache. I
changed some synchronization around and tried to to make the list remove cope
with the case where another thread has already removed the element. Before it
was just treating it like the only element, and quietly dropping the list (but
not the map -- yikes!)
Also, moved synchronization of spool to disk from Cache to LRUMemoryCache to
avoid a deadlock which occurred occasionally. Makes much more sense since that
method doesn't affect any of the volatile state in Cache.

- Implemented an internal queue for CacheEventQueue instead of the one from
util.concurrent. Looking at the unit tests this gets us a performance
increase from 25% ( for TestSimpleLoad ) to 75% ( The other two tests,
yes three times faster! ) More room for improvement I hope, but this
gets us back to where we were (it's actually a little faster then it
was when we were using JGL, but lots of other things have changed since
then. A big chunk of change came from moving the object creation for the
new node outside of the synchronized block -- who knew!
- Big changes to the way configuration works, trying to make things more
flexible, you can now get an unconfigured cache and configure it in a
couple different ways, possibly even more then once (that part is not
yet tested)
- Component wrapper for JCS! Still unsure about getting the properties
from the configuration, may just scrap it and move JCS to using the
configuration interfaces internally.

- Renamed CompositeCache to CacheHub, per todo.xml. Will post to the mailing
list regarding this shortly.
- Removed associated factory and put getInstance method in CacheHub (removing
DCL in the process =)
- Added some hackery to build.xml to allow the tests to run -- need to find a
more maveny way to do this in the long run.
