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.
Access document was added to exported data package too.
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).
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.
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.
Only delete some incorrect comment.
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.
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.
A method named hasReadPermission was added. The method will check if a user has permission toread a xml document.
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.
