Metacat

Added README explaining directory.

A series of queries and commands being developed to improve metacat
performance. Very incomplete. WARNING: running some of these commmands
WILL DELETE DATA. Do not run these commands in a production environment.

Revise test suite after moving Harvester properties to metacat.properties.

Initial suite of JUnit tests for Harvester code

JUnit files for tseting Harvester code

Sample harvest list XML file

Remove obsolete file

Added the EventLog functionality to the servlet as action=getlog. Valid parameters are ipAddress, principal, docid, event, start, end. All parameters can be repeated except start and end.

Partial implementation of a query facility for the access log. Need to fix problems with the date filtering, and tie this into the servlet action when completed and tested.

New EventLogTest modifying the log call to exclude revision.

Added classes for basic event logging support. These classes write log entries to the database connection. Still to do: query the event log, write oracle sql code (postgres is done), possibly allow the log to be archived to a text file, and possibly do the dtabase writes asynchronously via a caching mechanism.

Added a simple action for finding out the current metacat version. The information is pulled from the property file, so be sure to update the version in the property file before shipping a release.

Changed printAttributeQuery() to no longer depend on the xml_index table. Now, if useXMLIndex is false, the method will use a recursive query on xml_nodes to match paths instead of using xml_index.

Created new printExtendedSQL function that can get the extended
return fields using only xml_nodes and not xml_index. One
step closer to eliminating the dependence ofn xml_index.

Created test class QuerySpecificationTest and started process of removing the xml_index from the QuerySpecification code. Reformatted some classes for readability.

This is a sample of a harvest document relocated from the metacat/lib directory

Added more debugging messgaes to the test in an attempt to find out
what is wrong with the cookies.

Updated more tests on session reuse. Made the http calls set the sessionid
explicitly rather than relying on cookies being passed around statically.
Still need to modify HttpMessage to get rid of the static cookie.

New versions of the Metacat client API that allow access to the sessionId
so that a session can be reused over several different instances.

Fixed the sessionId handling code to now properly return the sessionId
in the login response message. Updated junit tests to test this issue.

Modified metacat to now provide the session identifier in the response
xml message when a login is called. This has not been fully tested.
I removed the HttpMessage class from metacat in favor of using the version
of that class that is found in the utilities module. This may cause some...

Revise this text file.

Add new test case to testing logout, user doesn't have permision to read, insert, update and delete documents. Add new test case to test inaccessible metacat.

Revise it.

Implemented the update and delete methods in the interface, along with tests.

New version of test document without illegal whitespace trailing the closing
tag of the root element.

New test data for testing metacat client.

Updated test so that the query test works. Now all tests should pass, but
still having the cntl-m issue on one server.

New test code for metacat client. Auto-generate id. Query and read from
the inserted document. Still having some problems with the tests.

Query.xml for testing MetacatClient.

Implemented the "insert()" method and wrote a test to test it. The new test
depends on the property "newdocid" be set to something unique in the build.xml
file so that the insert will work properly. Probably need to fix this to be
some kind of autoincrement counter or random number so that it can be run...

Refactored to use IOUtil routines. Reformatted for within-file consistency.

Add a test case for query method.

Implemented the 'read' API call. Some more to go...

Wrote the login() function, the first of the series of API calls for
the metacat client to be implemented. Also wrote a test class to
test the API functionality.

Get this big testing file(3.3 M) to reduce the distribution package size.

Change from assert to assertTrue.

Change assert to assertTrue.

Change assert to assertTrue

A new class to testing subtree class.

Add a example of attribute query.

Merge cvs branch replication to cvs head.

Change the test case order.

Add this file from branch to head.

This is code for testing how many sql commands one connection can be executed.

Change some debug message.

Change package name of this class.

Change package name. Factor of docid change from 10000 to 100000.

Change package name and data file path. The factor for docid change from 10000 to 100000.

This is the data file for testing insert data file action.

This is a net test file for metacat.

Add to cvs

Add metacat test to cvs.

This script file can run serials queries and print out the running time.

In order to test query performance. We need add lots of documents to database. This script file can add couple documents to database by for loop.

tests made on Oracle and SQL Server.

Added results of running the query analysis.

Analysis code cleanup.

modified analysis to add query_method (index or nested) as a
factor in the GLM.

Added data and statistical analysis code used for evaluation of the
query performance metrics for Metacat.
