	Bug Fixed in SQL-Query

2009-09-13	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	Refactored the persistent handling of the artifacts in the 
	artifact database. When an artifact is called (describe, feed,
	advance, out) a new CallContext is given instead of the
	old Object context. CallContext.globalContext() returns the
	old Object context now. CallContext.afterCall() may be
	called from inside describe, feed, advance and out to tell
	the artifact database what to do after the processing of
	the specific call.
	
	The accepted values are:
		- NOTHING    for doing nothing
		- TOUCH      for just update the last access time
		- STORE      for persisting the artifact.
		- BACKGROUND to signal that the artifact has started
		             a background operation.

	After the background operation the artifact has to call
	CallContext.fromBackground() to signal the artifact 
	database that the artifact needs to be touched or stored.

	!!! Without this call the artifact database assumes there
	!!! is still some background operation on this artifact
	!!! which prevents reclaiming resources

	* artifacts/src/main/java/de/intevation/artifacts/CallContext.java:
	New. New API to cope with background processing.

	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java:
	Replaced old Object context with CallContext context.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java:
	Adjusted.

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java:
	For a better encapsulation of the persistence operations of the
	artifacts the database does not return artifacts any more. It delegates
	the describe, feed, advance and out call to internal structures.

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabaseException.java:
	New. Simplifies handling of error conditions inside of artifact database.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	Adjusted to new interface. Internally it handles the background API.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactResource.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/FactoriesResource.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/OutRepresentation.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CreateResource.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactOutResource.java:
	Adjusted to new artifact database interface (which greatly simplifies things)

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
	Artifacts in background are not removed from database any longer.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java: Little
	re-wirering need for new cleanup.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java: 
	Simplified to do the SQL stuff only. The most infrastructure stuff is now done
	in ArtifactDatabaseImpl.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Id.java:
	New. Helper base class to enable filtering of background artifacts by there
	database id.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
	Modified the INSERT statement to write the serialized artifact, too.

2009-09-12	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java(out):
	out() is now called with an java.io.Outputstream to place
	the output.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/OutRepresentation.java:
	Adjusted.

	* artifact-database/doc/example-conf/conf.xml: Added
	sleep time for cleanup thread.

	cleanup thread to do an immediate cleanup when dead artifact
	is found by lookup.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
	New. The cleanup thread. It cleans up the artifact database
	perodically and calls the endOfLife() methods of the dead
	artifacts. Default cleanup interval is 5 minutes.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
	Tuned SQL a bit to fetch only a 50 artifacts in search for
	outdated artifacts to avoid too much memory consumption.

	* contrib/run.sh: Little tweak to work with more than one
	commons-pool version installed.

	* TODO: Removed remarks about the now implemented killer 
	thread and the moves XML stuff.

	* README: Changed text how to create a H2 database from
	command line only. XXX: This is still broken. The best
	way to set up the database by now is to start the Console 
	client, connect to the database, c&p the schema.sql 
	into the SQL text area and execute it.

	SQL statements for H2 database.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	Artifacts are proxies/wrapped by an special Artifact implementation

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactFactory.java(timeToLiveUntouched):
	Added this method to let the factory decide how long an artifact should live in ms.
	This is not a part of the Artifact itself because this is only evaluated once when
	the artifact is created.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java:
	New. Simple base class implementation of the Artifact interface.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactFactory.java:
	New. Simple base class implementation of the ArtifactFactory interface. When setup()
	on instances of this class is called, it pull ttl, name, description and
	the artifact class name from the node given. See artifactdb-example-conf.xml
	for examples.

	* artifact-database/pom.xml: Cleaned up XML. 
	Introduced dependency to apache commons dbcp, used for pooling of the 
	database connections to artifact db. 
	Added parameters for the exec:exec goal to make the project
	startable without building packages.

	* artifact-database/doc/schema.sql: Removed AUTO_INCREMENT from primary key
	to avoid compatibility issues with other non-H2 databases (PostgreSQL, Oracle, ...)
	which have no or limited support for generated keys in the JDBC driver. Now
	using an explicit sequence. TTL ist now big int to bring the resolution to ms.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java:
	Refactored a bit to make the XPath access function usable on arbitrary XML
	documents and parts of.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DBConnection.java:

	global configuration file. See artifactdb-example-conf.xml for examples.
	TODO: Write some documentation about this.

	* artifact-database/doc/artifactdb-example-conf.xml: Adjusted to be a more realistic
	example config file. Added references to DefaultArtifact/DefaultArtifactFactory and
	demonstrate how to configure the connection pool.

	* TODO: Add remark to document the connection file.
