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.

This is is a text file will be inert into metacat for testing. The content is "Hello, world".

This is new package and its testcase will involve morpho httpmessage class to insert data file.

Add the test case to insert invalidate xml and non well-formed xml documents.

Add two targets in build file: gethttpclient and nettest. gethttpclient wil checkout morpho and ran ant get httpclient.jar(cvs doesn't have httpclient.jar). nettest will run a junit test which will involve httpclient.jar file.

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 two variables here: one is runDBConnectionRecycleThread. If it set "on", the recycle connection tread will run periodically. The other is cycleTimeOfDBConnection. This is for the recycle periodical time in milli seconds.

Add some new methods in this class.

Add some variables to control db connection.

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 some debug message in the code.

Add a variable named junittesturl there.

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

Add test case for inert, read, update, delete xml documents and logout action too.

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

Change datafilepath's value and it should equals the property value of datafilepath in build.xml.

Add a variable named datafilepath in it. MetaCat administrator should specify the absolute path for storing data file.

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

Add two variables replicationsenddata and replicationacceptdata

Add two variables named replicationsenddata and replicationacceptdata. Metacat administrator can configure metacat can send or accepte or both to 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 a variable named debuglevel here. It control the differrent debug level message will be printed.

Add a property named debuglevel in it. This property will control the debug message. It set higher, more debug message will print out

This file now contaions login testing for nceas, pisco and lter ldap server. It includes both successful and failed login testing.
More testing such as insert xml document and data file ... will coming.

Revise junit testing part and make it working.
Delete the variables for httpclient.jar and junit.jar

This jar file can be deleted.

This jar file will install in ant/lib.

Add two variables junit and httpclient in cpath

In order to implementate junit, this jar file is needed.

In order to test MetacatServlet, we need use HttpMessage class, so add this jar file

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.

Adding a variable "hub". If hub=super, the metacat can replicate the documents and data file which's home host is not itself.

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 a new variable datafileflag. This variable will indicate if a document is a data file in updated documents list in replication.

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 some new format.
