1042 04/30/2002 08:29 AM Jing Tao

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.

1041 04/30/2002 08:25 AM Jing Tao

1035 04/26/2002 05:30 PM Jing Tao

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

1034 04/26/2002 05:27 PM Jing Tao

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

1032 04/25/2002 05:02 PM Jing Tao

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

1031 04/25/2002 05:01 PM Jing Tao

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

1020 04/19/2002 06:52 PM Jing Tao

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.

1016 04/18/2002 03:35 PM Jing Tao

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....

1015 04/16/2002 06:21 PM Jing Tao

Fixed the bug that handle force replication

1014 04/16/2002 06:20 PM Jing Tao

Fixed the bug that to handle forceReplication action

Add a method named getLocalReplicationServerName

1012 04/16/2002 06:18 PM Jing Tao

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

1011 04/15/2002 06:04 PM Jing Tao

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.

1006 04/11/2002 08:35 AM Jing Tao

Fixed getGroup method return a exception and cause authenticate failed.

1005 04/11/2002 12:18 AM Matt Jones

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...

1004 04/10/2002 10:04 PM Jing Tao

Some changes for pisco.

1002 04/10/2002 03:51 PM berkley

turned debug off for the release

1001 04/10/2002 03:18 PM berkley

1000 04/10/2002 02:09 PM berkley

fixed groups error, I hope.

991 04/09/2002 08:31 AM Jing Tao

fixed auth bug

980 04/04/2002 01:36 PM berkley

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

979 03/29/2002 06:35 PM Jing Tao

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')

976 03/22/2002 02:24 PM Jing Tao

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.

975 03/18/2002 05:02 PM Jing Tao

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

968 03/08/2002 02:41 PM Jing Tao

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

966 03/07/2002 02:14 PM Jing Tao

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.

965 03/06/2002 06:30 PM Jing Tao

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.

963 03/06/2002 04:17 PM berkley

fixed my tagging error

962 03/06/2002 03:58 PM berkley

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

961 03/06/2002 09:00 AM Jing Tao

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.

959 03/05/2002 01:14 PM Jing Tao

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.

958 03/05/2002 01:11 PM Jing Tao

Add a throwing exception in hasPermission and hasReadPermission methods.

957 03/05/2002 01:09 PM Jing Tao

Add a throwing exception in haspermission method.

956 03/05/2002 11:38 AM Jing Tao

A constructor for this class was added. In the new constructor, user can specify the revision number he want to update. In method writeDocumentToDB, when a update action happend, the rev number would not automatictlly to add one, but it can go to specified number. This is for bug 417.

955 03/05/2002 11:33 AM Jing Tao

A constructor was added to this class. In this constructor, user can specify the revision number he want to update. And the number can be passed into a DocumentImpl object constructor in startElement method. But the number should be greater than current number in database.

954 03/05/2002 11:28 AM Jing Tao

A method named getLastRevisionNumber was added. And condition for checking accession number was revised too. Now metacat wouldn't refuse a revsion number which is 2 or more greater than current revision number in the database. This is for bug 417.

953 03/05/2002 09:19 AM Jing Tao

Access document was added to exported data package too.

952 03/04/2002 08:34 PM Jing Tao

The method - hasAllowRule was revised. If a action -read or update was approved, all ticket count of allow rule entries for this action will minus one if the entries have ticket count number (not null).

951 03/01/2002 06:07 PM Jing Tao

The two hasPermission methods were rewritten. Some logic bugs were fixed. Now user, public and group will not be checked speratedly, but they will be check together as string array. In order to do this, private methods isAccessDocument, containDocumentOwner, isAllowFirst, hasAllowRule, hasExplicitDenyRule, hasImplicitDenyRule, and createUsersPackage were added.

950 02/26/2002 02:02 PM Jing Tao

In method transformXMLDocument, if no style sheet registered was found for the input document, the document will be send back, rather than use util.DebugMessge to print.

949 02/26/2002 01:55 PM Jing Tao

Only delete some incorrect comment.

948 02/26/2002 01:53 PM Jing Tao

When user request a data package, the old version documents would be exported. Only export the request one.

During the export function. Every document will be check if the user has the permission to read or not.

947 02/26/2002 08:37 AM Jing Tao

The feature of check permission before Metacat handle a "read" action. If user doesn't have permission, its request will be rejected.
After creating a DocumentImpl object. A method named hasReadPermission in that class will be called to make sure the user has permission to read it.

946 02/26/2002 08:30 AM Jing Tao

A method named hasReadPermission was added. The method will check if a user has permission toread a xml document.

945 02/26/2002 08:23 AM Jing Tao

A new method named hasPermissionToExportPackage was added. So when MetaCat handle export action, it will check if user has permission to read the data package. If it has, MetaCat will export a zip output stream to it. Otherwise, MetaCat will be through a exception.

944 02/26/2002 08:18 AM Jing Tao

Code to handle "read" permission was changed in hasPermission method. The old code used old way to look up the public_access field in xml_documents table.

943 02/22/2002 03:02 PM Jing Tao

A new action named export was add to it. This action will export a zip output stream for a data package. In the zip output stream, meta data documents, data files and a html summary file are include. The stucture will looks like:
package----/metadata/metadata docments...

942 02/22/2002 02:56 PM Jing Tao

Two metacat util methods were add. One is getDocIdFromString and the other is getVersionFromString. They output a docid and revision if a string like str1.str2.str3. were passed to them.

941 02/22/2002 02:53 PM Jing Tao

A method named transformXmlDocument were overload. It transform an XML document to StringWriter using the stylesheet reference from the db.

940 02/22/2002 02:50 PM Jing Tao

A public method named getZippedPackage() and other relative private methods were add to this class. The public method can give a zip output stream if a docid and other parameters were passed to it.

935 02/13/2002 05:48 PM Jing Tao

Some code format problem was fixed.

934 02/13/2002 03:17 PM Jing Tao

The bug was fixed.
After a referral exception happend, we should set enviroment properties again before creating a contex. These environment properties include PROVIDER_URL, SECURITY_PRINCIPLE, SECURITY_CREDENTIALS, REFERRAL, and INITIAL_CONTEXT_FACOTRY. Otherwise, you couldn't get a naming exception.

930 02/12/2002 09:14 PM Jing Tao

Authentication bug was fixed (bug 408).
However, it needs to test if referral cotaining a referral.

928 02/11/2002 05:56 PM Jing Tao

Please check it.

927 02/11/2002 08:10 AM Jing Tao

In order to fix bug 408 (authentication), some important variables' values
were followed.

920 02/02/2002 01:14 AM Matt Jones

Set the qformat parameter so the stylesheets can use it for conditional
processing.

915 01/29/2002 10:15 AM berkley

fixed error I introduced when I got postgres working
