Subject jcr-server: summary of changes [rev. 331281]
Date Mon, 07 Nov 2005 18:01:42 GMT

a couple of issues have been addressed in the jcr-server
JCR-249 caused major changes in the o.a.j.server.io package
which are discussed in the corresponding jira issue.

please note also a modification in the simple-servlet suggested
by felix (see below).

JCR-249 (http://issues.apache.org/jira/browse/JCR-249)

- command chains have been replaced inside the server project
   > removal of all command, commandchain classes
   > removal of catalog.xml
   > references to command-chains in other classes have been
     removed or replaces.
- the new import/export framework is described in JCR-249
- while replacing the command-chains i modified some IO
   related things in the webdav-project, too.
   see below for details.

JCR-253 (http://issues.apache.org/jira/browse/JCR-253)

fixed by tobi as suggested.

Removing basic auth handling from RepositoryAccessServlet

fixed by tobi

getCredentialsFromHeader has been removed from the RAServlet and
added to a new BasicCredentialsProvider class.
The corresponding servlet init-param has been added to the
SimpleWebdavServlet and the JcrServerServlet.

changes in webdav library (consequence of JCR 249)

- o.a.j.webdav.io contains now interfaces for general
   input/output and 2 implementing classes that are
   used in the AbstractWebdavServlet.

- o.a.j.webdav.DavResource now is responsible for
   writing its properties/content to the OutputContext.
   therefore the getStream() methods has been replace.
   The spoolResource-method in the abstract-dav-servlet
   does not care about individual headers and the spooling
   any more, but delegates this to the resources.

- o.a.j.webdav.DavResource.addMember(DavResource) has
   been removed. There remains only one single addMember
   method that takes a resource and an InputContext.
   thus, a MKCOL that does not have a request body will
   provide an InputContext without a stream but allows
   to forward the request headers to the dav-resource.

additional changes in the simple-server

- NodeResource became obsolute (JCR-249) and has been

- DavResourceImpl:
   > protected methods for getting a new Import/ExportContext
     in order to respond to GET/HEAD and PUT/MKCOL, respectively.
     the default context implementations delete the tmpfiles
     created for import/export as soon as the context is
     released (avoiding deleteOnExit).
   > initProperties retrieves the dav-properties without
     the data being spooled.
   > the check for filtered-node in the constructor has
     been removed (problems with days crx)

- SimpleServlet:
   felix suggested to always add the workspace name to resource
   URIs. the default locatorfactory in the simple servlet was
   replaced for this reason.
   NOTE: since there is not extra fake-root resource, the webdav
   connection now needs to include the workspace name. this
   corresponds to a repository-login that provides a workspace
   name. before it was not possible to connect to a specific

javadoc, todo, README

- removed day-header in LoggingServlet
- and tobi corrected some of my javadoc typos.
- the readme and the todo.txt were a little outdated.
