Metacat

Change back to pass connection as paramter in getUniqueID, otherwise new connection will cause a error:
sequence XML_NODES_ID_SEQ.CURRVAL is not yet defined in this session

Add a new method - createStatement.

Correct the parameter of getDBConnection - methodName in code.

Change for every method to use getDBConnection and returnDBConnection to manage DBConnection.

Using getDBConenction rather than pass connection as parameter.

Using getDBConnection rather than pass connection as a parameter.

Using getDBConnection method rather than a parameter.

Change the prototype of method getUniqeID

Add DBConnectionPool object in servlet's init method and DBConnectionPool's release method in servlet's destory method.

Delete connection as a class field and make every method to check in and check out connection if it need.

Make a every method check in and check out DBConnection if this method need a connection.

In returnDBConnection method, a new parameter named serialNumber was added. It will compare to the checkOutSerialNumber in DBConnection.

Add a new attribute named checkOutSerialNumber, which to make sure when DBConnection would not be check in mutiple times.

Add the code to handle error in the respone for a update request.

Add test ssl work or not in handleUpdateRequest method too.

Change code to handle the error message.

Add error message to outPut in catch clause in handleGetDocument Request.

In update method, add code to handle if a user couldn't pass a trusting test.

Add a test action in replication. Before handle read and read data file action. Metacat will take a test to see if the trust key in key store. If not, wouldn't replicate documents.This is security issue.

Add debugMessage level in this class

Add a method getDBConnection. In this method, method name of method which checked out the connection can be passed to DBConnection object. In run() method, if a connection is checked out for too long (30 seconds), the method name and connection name will be print out.

Add a attribute named checkOutMethodName and relative method. This variable can keep track which mehod check out the DBConnection.

Add some new methods into this class.

Add some new methods in this class.

Add some new methods in it. Remove openDBconnection part to DBConnection class.

Add some new attributes and methods in it.

Add a new class named DBConnectionPool. This class will create DBConnection pool and other user can get or return connection to it.

Add this new class into meta package. DBConnection class repsent a conncetion and its information.

Add setCookie method in this class. Junit test class need this method.

Add a access control for MetaCatServlet to update a document which home server is not local metacat.

Add a control to accept data or not

Add two controls to send or accept data.

Add control to send data or not

Add two control for send or accept data file

In writeDocumentToDB method, during insert action, rev value can be assigned too. It is useful for replication.

Revised update method.

Add a control to get data file granted in handleUploadMethod.

Revised the method writeDataFile, writeReplication and writeToDB

Revise Update method.

Apply DocumentImp.writeReplication and DocumentImp.writeDataFile in deltaT replication

Fixed some db connection problem

Fixed some db connection bug.

Delete a some useless code for connection pool

Fixed some DB connection bug.

Assign debug level to parser. (it level is 50)

Use DocumentImpl.getDocHomeServer method to get home server in method handleGetDocumentInfo

Change the method getLocalReplicationServerName to be static

Add the feature to get doc home server into method getDocumentInfo.
Add a method to return docHomeServer.

Fixed a bug in method getHomeServer

Revise the method getDocumentInfo. Home server of documnet is added in it.

Revised handleUploadRequet.

Add three methods into this class. One is named getServerCode, to given a server name, it return server code in xml_replication table.
One named insertServerIntoReplicationTable, if a server is not in the server list, it will insert it.
One is named WriteReplication, this method will be used in forceReplication. It delete the replication code in it.

Delete the control that when action="insert", rev should be 1

Overload a method debugMessage(String msg, int debugLevel)
User can set a debugLevel for this message. If debugLevel is less than the default a value in build.xml, this message will be printed.
If user set a value less than or equals 0, debugLevel will be set automatically to 1. So we can set default value to 0 in build.xml file and close all debug message.

Add two methods getHomeServer and getServerLocation. Given a docid, getHomeServer can get the information of its home host. Given a docid, getServerLocation can return server code for it.

In handleUpdateRequest method, if a metacat was configured to be hub super, it can provide any documents in its database. If the metacat is notsuper, it only provide the documents list which home host is itself.

Adding a hub control to data file in handleUpLoad method. Data file was changed can be replicate to all server or only home host.

Add a hashtable - server list as a class variable. So programmer have a control to the server list which will be forced to replicate.

Add a hub control in write and writeData method. If hub==super, metacat can replicate any document in its database to any server in server list. If it is not super, metacat only replicate local documents to any server in server list. If a document' home host is not itself, metacat only force replicate the document to the document's home host.

In update method, adding some code to handle replicate data file. Fixed the bug in deleting documents.

Making parser to handle datafile attribute in parsing updated doclist.

Add a new attribute in updated doc list: data file. So from this attribute, we can tell which document is a data file.

In writeDataFile method, using getDataFileLockGrant(docid) replace getDataFileLockGrant(docid, serverCode). The latter will cause a problem

Add two controls for handle replication server list is empty and updated document list is empty

Using DocumentImpl.writeDataFile method in handleReplicateDataFileRequest. Make code simple.

Add a control to handle if the server list is empty.

Add a method named writeDataFile. This method will register data file into xml_documents table and save a input stream to a file.

Adding a new feature that in uploaddatafile that the datafile can be replicated.

Adding a control which can turn on or off replcation data file.

Add method getDataFileLockGrant(). This method will check if xml-document of data file can be store into database.

Add two method: handleGetDataFileRequest and handleForceReplicateDataFile. The two methods will handle data file replication.

Adding handle force replication data file part.

Add a new method named unRegisterDocument. This method will delete the record in xml_document table which is for a data file

Figure out the configuration issue about replication. If metacat was configured to set replication off in build.xml, it will reject replication.

Adding a method named handleGetDataFileRequest. User can download data file from replcication now.

Currently, some document in xml_document table doesn't have entries in
xml_access table. This is okay during the old access policy.
But we changed the access policy( see bug 437 ) and if there is no entry in
xml_access table, except owner, other person can not access it....

Fixed the bug that handle force replication

Fixed the bug that to handle forceReplication action

Add a method named getLocalReplicationServerName

Fixed the bug metacat will set server location to 1, no matter it is.

Fixed the getall didn't work. Now local host can insert or update documents from remote host.
But still there some problem on force replcation.

Fixed getGroup method return a exception and cause authenticate failed.

Fixed the getIdentifyingName() sub so that it properly looks up someones
DN if passed in a DN that is an alias. This is mainly important for
sites like PISCO that use a different root to their tree than the
ecoinformatics.org tree. Now we can successfully authenticate againast...

Some changes for pisco.

turned debug off for the release

hopefully fixed the connection closed error.

fixed groups error, I hope.

fixed auth bug

updated authldap to get the groups to work (king of)

Change every "http://server to "systemidserver". It will look like:
INSERT INTO xml_catalog (entry_type, public_id, system_id)
VALUES ('DTD', '-//ecoinformatics.org//eml-software-eml-version//EN',
'systemidserver@html-path@/dtd/eml-software-eml-version.dtd')

Method getGourps was revised. Attributes variables were set there. Other wise, when it caught a referral exception and started a thread, this will caused a exception problem. When string array groups were returned by method getGroups in getPrincipals method, we should check if the groups is null or not. Otherwise it will cause a exception problem. This revise is for bug 445.

In hasPermission method, a situation was considered: if no user and group, the permssion will be true. This is for the command line invocation.

Method endElement in AccessControList was revised. A feature that put access document itset into xml_access was added.

In hasPermission method, a rule for access document is implements. If user want to write a access document, it should hhave "all" permission.
The permission for access document now is looking up in xml_access table directly, rather get same permission to data set document.

In order to increase data file docid, method registerDocument was revised. Now it not only insert a new data file record to xml_documents table, but also can update the data file documents. Moreover, it can archieve the old version to xml_revisions table. Two other private methods were added to handl these futures: deleteXMLDocuments and getLatestRevisionNumber.

fixed my tagging error

some small changes I had to make to get the QAENGINE demo to work right. this should be committing in a branch

We decided that the permission for a user to an access documents is as same as to the data set document(which contains the access document). In order to do this, we need to look-up xml-relation table. If we could find the data set document id, just check the id. If we couldn't find one, we need check if the user is owner. If it is, has permission. Otherwise, doesn't have.

Add a new method getDataSetId to the class. The permission policy for access documents is: the user will have the same permission as data set file. (There is no entry in xml_access table for access document.

Add a throwing exception in hasPermission and hasReadPermission methods.

Add a throwing exception in haspermission method.
