metacat @ 772

# Date Author Comment
772 06/05/2001 12:24 PM bojilova

cleared the COLLATION specifiers on column definitions:
it is new in SQL Server 2000 and not supported in its earlier versions

771 06/04/2001 02:07 PM bojilova

excluded revisionid from the insert statement for xml_revisions.
It is identity column for SQL Server or filled by sequence for db as Oracle or Postgres

770 06/04/2001 01:47 PM bojilova

changed like with =

769 06/01/2001 04:14 PM bojilova

changed ... WHERE ... LIKE ? ...
to ... WHERE ... = ? ...

768 06/01/2001 04:12 PM bojilova

MS SQL Server stores trailing spaces in varchar fields which shouldn't be
thus added docid.trim() in the Java code

766 06/01/2001 01:26 PM bojilova

the ODBC multi-threading problem:
in DBQuery we open ResultSet in the db connection and we are trying to
open another Resultset by AccessControlList which does not work
thus open separate connection for use by AccessControlList.

765 06/01/2001 12:51 PM bojilova

changed
SELECT ... WHERE LIKE ? ...
to:
SELECT ... WHERE = ? ...

It should be changed everywhere it is found

764 06/01/2001 12:14 PM bojilova

seems that there are problem in JDBC-ODBC bridge used with SQL Server
when using sql statements like:
SELECT ...
WHERE LIKE ? ...
changed to:
SELECT ...
WHERE = ? ...
and now it works

763 06/01/2001 12:12 PM bojilova

commented out the use of oracle.jdbc.driver
this was harcoded use for batching the sql calls at once in order to speed up the insert of XML Index

762 06/01/2001 12:08 PM bojilova

added
INSERT INTO xml_replication (serverid, server, replicate) VALUES ('1', 'localhost', '0');
which was missing

759 05/31/2001 05:26 PM bojilova

several changes were needed related to the change of the unique id generation and use

758 05/31/2001 05:24 PM bojilova

Changed the order of generating and getting Unique ID for
xml_nodes.nodeid and for uniqueid part of the accession#
because of SQl Server capabilities:
first let the db to generate unique id on insert (by db trigger and sequence or by IDENTITY key),
then get that unique id for further use by the application....

757 05/31/2001 05:18 PM bojilova

- new db adapter for MS SQL Server
- changed the getUniqueID(conn, tableName) to return the last generated by the db unique ID
instead of generating unique ID first by the appl and then supplied to the insert,
because SQL Server doesn't have capabilities
unique ID to be generated on the client and then supplied to the insert.

756 05/29/2001 05:17 PM Matt Jones

Updated pathquery.dtd to reflect new addition of filterdoctype element.

755 05/29/2001 11:09 AM bojilova

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

754 05/24/2001 11:21 AM bojilova

change the call from getDateFunction() to getDateTimeFunction()

753 05/24/2001 11:07 AM harris

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

752 05/24/2001 10:21 AM bojilova

change the call from getDateString() to getDateFunction()

751 05/24/2001 10:20 AM bojilova

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

750 05/24/2001 09:01 AM harris

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.

749 05/23/2001 03:28 PM bojilova

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

748 05/23/2001 03:26 PM bojilova

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

747 05/23/2001 03:19 PM bojilova

- 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....

746 05/23/2001 03:06 PM bojilova

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

745 05/22/2001 03:24 PM Matt Jones

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...

744 05/21/2001 02:30 PM Matt Jones

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.

743 05/21/2001 01:51 PM Matt Jones

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"...

742 05/16/2001 09:45 AM bojilova

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

741 05/09/2001 01:54 PM harris

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

740 05/09/2001 01:49 PM bojilova

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.

739 05/08/2001 02:40 PM bojilova

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; }...

738 05/04/2001 02:30 PM bojilova

fix to view abstract only when abstractpath parameter was specified

737 05/04/2001 02:25 PM bojilova

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

736 05/04/2001 11:12 AM bojilova

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

735 05/04/2001 09:16 AM bojilova

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

734 05/03/2001 05:12 PM bojilova

- 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...

733 05/02/2001 02:52 PM bojilova

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"...

732 05/01/2001 04:43 PM bojilova

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

731 05/01/2001 04:42 PM bojilova

- 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.

</user>
</group>...

725 03/05/2001 04:25 PM bojilova
