Metacat

- made xmltables-sqlserver.sql from SQL Server running here on rincon machine
- included db index on xml_nodes.nodename which was missing

change the call from getDateFunction() to getDateTimeFunction()

changed the getDate method to getDateTime and changed the return
string in the postgresql implementation to "now()" from now()::date

change the call from getDateString() to getDateFunction()

change the method name getDateString() to getDateFunction()
return "now()::date" in the DBPostgresql implementation of that method

The Postgres implementation of the dbadapter package, still needs testing and
the getDate... method just returns the db function to return the date; to retreive the
current time is a second function so we may want to add a second method to return the
current time.

changed the db sequence name used for the accession# uniqueid
to xml_documents_id_seq.
All db sequences now are named of form <table_name>_id_seq

added new property for the dbadapter class as:
dbAdapter=edu.ucsb.nceas.dbadapter.DBOracle
the installation procedure should change it to the appropriate class

- changed to use the DBAdapter uniform interface for all apperance of "sysdate"
and uniqueid generation from sequence
MetaCatUtil:
- reads from metacat.properties the dbadapter class implemented the interface
and creates an instance of that class (in static public variable named dbAdapter) for use....

the abstract DBAdapter class and its Oracle implementation
for the new dbadapter package

Fixed bug in metacat where return doctypes were not being properly
back traced. Changed DBQuery.findDocuments() so that it no longer
takes a returndoc array, but instead retrieves the returndoc array
fromthe QUERYSpecification. The QuerySpecification was augmented...

Added ability to process multiple "returndoc" elements in
a pathquery document. Now, any query hit will be back traced to an
associated package if that package is listed in one of the
"returndoctype" elements.

Modifications that change the package handling behavior of metacat. Package
membership is now determined by an identifier being used as either the subject
or object in a triple. One can not request arbitrary returndocs -- only
those types that have package information embedded can be "returndoctype"...

fix in the return of the last revisionid on UPDATE instead of the previous one

this is sql script does the same as the sql script named
xmltables.sql except that this script is to be use to
create the database tables on a Postgresql backend rather
than an Oracle Backend

the foreign-key constraints still need to be fixed

fixed the problem with empy password authentication.
Ldap somehow allows DirContext to be created
when empty password is provided as in our case
instead of comlaining like with wrong password string.
So included a check for empty password in order to reject the login.

as John were testing Metacat on postgres,
he discovered that Connection needs more precise check
whether it is open because of db timing outs.
So used to be:
if ( conn null ) { get new connection from db; }
Now changed to:
if ( conn null || conn.isClosed() ) { get new connection from db; }...

fix to view abstract only when abstractpath parameter was specified

specified the correct param list about the "read" action changes

put exception handler messages when acc# is not in the correct format as:
<sitecode>.<uniqueid>.[<revisionid>]

fix - added back generate(docid, action) method called from DataFileServer.java where rev is defaulted to 1

- changes to expect revisionid to come from the client on INSERT/UPDATE/DELETE;
now the client should send accession# as:
sitecode.uniqueid.revisionid
INSERT checks if sitecode.uniqueid part does not exist in xml_documents and xml_revisions and revisionid=1...

Tomcat has got configurated mime type mappings, but some are
missing. Thus added support for them in MetaCatServlet as:
File type > MIME type
------------- ----------------
.xml -> "text/xml"
.xsd -> "text/xml"
.dtd -> "text/plain"
.css -> "text/css"...

chaged the hidden input box from "relation" to "docid"

- merged "getabstract" and "getdatadoc" actions to "read" action;
- put MIME types everywhere for the returned data;
- zip when more than one doc/files were requested or when specified by qformat="zip" parameter;
- get rid of "relation" parameter, instead use "docid" parameter name only - when more that one docid - zip them;...

Changes related to running LDAP servers referred each other in one tree modeling the KNB tree.
Currently there are running LDAP server on dev that holds the KNB root and the NCEAS' s subtree.
It also refers to a subtree modeling the LTER's tree which is held by another LDAP server runnig on alpha .

uncompleted script file to create DB on SQL server

fixes on getting information from LDAP services

added check to see if a replication server's IP matched it's DNS entry and the entry in the replication table

fixes around getUsers and getGroups.
"getprincipals" action can now produce output like:

<principals>
<group>
<groupname>Administrators<groupname>
<user>
<username>uid=admin,o=NCEAS, c=US<username>
</user>
</group>...

Included back getting the list of users and groups stored in auth scheme
through new action="getprincipals". No extra parameters are needed.
Any logged in users are able to get this information

Module cleanup inpreparation for a release.

Solving the problem with relication of access file where access files were rejected from the replication servers.
In AccessControlList check for serverCode is included,
so only on the local server the connected user is checked for having "all" permissions on the resources specified in it...

fixed some problems with database connections getting a time out error. Also updated some catch statements
