2010-03-19 Ingo Weinzierl <ingo.weinzierl@intevation.de> Issue208 (Artifact gets a new identifier after being imported) * artifacts/src/main/java/de/intevation/artifacts/Artifact.java: Added a new method setIdentifier(String identifier). * artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java: Default implementation of setIdentifier(String identifier) to give an artifact a new identifier. * artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java: Set a new identifier on an artifact after deserializing it. * artifact-database/src/main/java/de/intevation/artifactdatabase/ProxyArtifact.java: Set the identifier of the proxied artifact right after setting its own identifier. 2010-03-19 Ingo Weinzierl <ingo.weinzierl@intevation.de> Issue208 (Artifact import) * artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ImportResource.java: New server resource to import an artifact from an incoming xml document. The resource is available as /import and accepts xml documents send via HTTP POST. * artifact-database/src/main/resources/sql/org-postgresql-driver.properties, artifact-database/src/main/resources/sql/org-h2-driver.properties: New sql statements to update an existing artifact. * artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java: New method to import an artifact from an incoming xml document. The data contained in this document is decoded using the secret. * artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java: New method to store an artifact into database or replace it if an artifact with the given id is already existing. * artifact-database/src/main/java/de/intevation/artifactdatabase/StringUtils.java: Removed method to convert a byte array into a string (this is done by Apache's Hex class in commons codec) and added a new method to convert a string into a byte array using Apache commons codec as well. * artifact-database/src/main/java/de/intevation/artifactdatabase/rest/RestApp.java: Register ImportResource to webserver. * artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java, artifact-database/src/main/java/de/intevation/artifactdatabase/SQL.java, artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java, artifact-database/src/main/java/de/intevation/artifactdatabase/Id.java: Converted the author javadocs. 2010-03-16 Ingo Weinzierl <ingo.weinzierl@intevation.de> Issue208 (Artifact export) * artifact-database/doc/example-conf/conf.xml: Added a section to configure a secret string used to identify artifact imports for security reason. Incoming artifact imports need to be identified with this secret, otherwise the import should be blocked. Xpath for this secret: '/artifact-database/export-secret/text()' * artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java: New attribute 'exportSecret' and some code to read the secret from configuration while application startup. * artifact-database/pom.xml: Added Apache Commons Codec library used to encode/decode artifact data. * artifact-database/src/main/java/de/intevation/artifactdatabase/StringUtils.java: New utilities class for frequently used string operations. * artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java: Added some methods for exporting artifacts as xml documents. The data part is base64 encoded. A secret key is used while encoding this data to verify artifact imports, later. * artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java: Added an artifact loader interface used to deserialize artifacts. getArtifact() implements such an ArtifactLoader to return PersistentArtifacts. * artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ExportResource.java: New. ServerResource to export artifacts (innerGet). This resource is available under "/export/{uuid}" via HTTP-GET request and returns an artifact specified by uuid as xml document. * artifact-database/src/main/java/de/intevation/artifactdatabase/rest/RestApp.java: Register ExportResource to webserver. * artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java: Added method to export artifacts. * artifact-database/src/main/java/de/intevation/artifactdatabase/App.java: Reset bootstrap after application startup. 2010-03-11 Sascha L.

Now it is possible to send further Informations to the Artifact using the XML-Document. This is nessesary for manipoulating the Artifact e.g. setting Parameters which should only be displaied or e.g. put an Geometry-Object into the Artifact which should limit the displayed results. 2010-01-27 Hans Plum <hans@intevation.de> RELEASE 0.4 * Changes, NEWS, ChangeLog: summarized activities. 2010-01-22 Sascha L.

Teichmann <sascha.teichmann@intevation.de> * artifacts/src/main/java/de/intevation/artifacts/CallContext.java: Added a context dictionary accessible through putContextValue(key, value) and getContextValue(key). Purpose is make artifact calls stackable and transfer information through the call level transparently. * artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java: Adjusted default implementation of CallContext. * artifact-database/src/main/java/de/intevation/artifactdatabase/ProxyArtifact.java: New. A general proxy class for artifacts in artifact databases. This class uses the extended call context semantics. The artifact calls (feed, describe, out, ...) are passed to a proxied artifact. If the proxied artifact decides to be replaced by some other artifact it has to to store a reference to the replacement artifact in the call context with putContextValue(ProxyArtifact.REPLACE_PROXY, my_new_artifact). After the call is finished the proxied object will change. This indirect callback mechanism is used to minimize side effects. The identifier() call is not forwarded to the proxied artifact to have a stable id. Limitations: This mechanism does not let you build real matroska (multi level) like artifact structures. This would only be possible if a kind of call context stack is introduced. 2009-11-13 Hans Plum <hans@intevation.de> RELEASE 0.2 * Changes, NEWS summarized 2009-11-11 Ingo Weinzierl <ingo.weinzierl@intevation.de> * HOWTO: Added HOWTO describing the setup of the environment (apache, tomcat, gnv). 2009-11-04 Sascha L.

The request body is handled as XML. 2009-10-21 Tim Englich <tim.englich@intevation.de> Issue 59: Make paths in configuration relativ * src/main/java/de/intevation/artifactdatabase/Config.java (replaceConfigDir): Applied patch from slt to set the Configuration Folder into the AbsoluteFileName issue59 2009-10-07 Sascha L.

Teichmann <sascha.teichmann@intevation.de> * artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactResource.java: More warning log output in POST case. 2009-09-15 Tim Englich <tim.englich@intevation.de> * src/main/java/de/intevation/artifactdatabase/Backend.java: Bug Fixed: Comparation for outdated Artifacts was Wrong. * src/main/java/de/intevation/artifactdatabase/rest/ArtifactResource.java (represent): Warn-Logging Integrated for Exception analysys. 2009-09-14 Tim Englich <tim.englich@intevation.de> * src/main/java/de/intevation/artifacts/ArtifactFactory.java Edited: Make Objects Serializable * src/main/resources/sql/org-h2-driver.properties: 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.

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. 2009-09-10 Sascha L.

The configuration is now found in a subdirectory set by the system property 'artifact.database.dir'. If this property is not set '~/.artitactdb' is used. This directory should contain a file 'conf.xml' with the configuration details. If the artifact database is started as a standalone the config directory is searched for 'log4j.properties' to configure the logging. The H2 database is also search in this directory with the name 'artifacts.db' if the connection url in config.xml is not overwritten. * artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java: Refactored a bit to follow the new configuration policy. * artifact-database/src/main/java/de/intevation/artifactdatabase/DBConnection.java: Build default connection url as described. * artifact-database/doc/example-conf/log4j.properties: New. example logging config * artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java: Added some more logging infos. * artifact-database/src/main/java/de/intevation/artifactdatabase/App.java: Load the log4j configuration at startup and starts a REST standalone web server. * artifact-database/src/main/java/de/intevation/artifactdatabase/rest: New.
