New Revision: 568113
URL: http://svn.apache.org/viewvc?rev=568113&view=rev
Log:
1. TestCastorXmlPageManager test case always fails because it transforms UTF-8 encoded psmls to ANSI encoded psmls by an xsl page during the setUp stage.
- This problem was caused by o.a.j.page.DirectoryXMLTransform.java. It should use FileOutputStream for a StreamResult instead of FileWriter.
2. If we do load tests with many concurrent users (e.g. 200+ users), th e following exception occurs:
"Could not unmarshal the file /home7/xep/Jetspeed-2.1.2/webapps/jetspeed/WEB-INF/pages/folder.metadata
FWK005 parse may not be called while parsing."
- This problem was caused by o.a.j.page.document.psml.CastorFileSystemDocumentHandler.java. The unmarshallDocument() method was not thread-safe because it uses xmlReader member variable. The SAX XMLReader must not be shared among concurrent threads.
- However, this problem could not be found often because if a document is just cached then the unmarshalDocument() method would not be called. So, when there's no cache of documents and many concurrent users rush to the system, this problem can occur. The system used to just leave a log with stack traces, not giving complaints to users.
- TestCastorFileSystemDocumentHandler.java is a unit test code for this.
