Nicolas Toper updated JCR-442:
------------------------------
Attachment: patch-jr-final1.tar.gz
This is the proposed path to the core for the backup tool.
Sorry for the 4 patches but some Gremlins have invaded my computer and created
a lot of problem with SVN.
Here are the modifications I propose:
- Update to PropInfo.
Please see relevant thread on ML.
- Update to VersionManagerImpl and to RepositoryImpl.
In order to restore the NodeVersionHistories, I need to gain access to the
VersionManagerImpl persistence (through a getter) manager. For this, I need to
put the getVersionManager() of RepositoryImpl in public (I couldn't use the
one from SessionImpl since there can be a XAVersionManager and the cast to
VersionManagerImpl doesn't work in this case)
- Add a NodeVersionHistoriesUpdatableStateManager
It is a specific UpdatableStateManager designed specifically to update the
NodeVersionHistories. It is heavily based on the LocalItemStateManager.
I have to be able to connect the imported NodeState so I had to put this class
in the o.a.j.core.state package and couldn't put it in the backup one. (connect
is protected to state and it is *really* a bad idea to put in public).
The idea was to be able to work with a BatchedItemOperation class so to keep as
much as possible its original semantic.
I am sure there is a better way to handle those needs instead of updating the
core but I didn't find any yet.
As soon, as we all agree, I will update the relevant part of my code (in backup
and in this patch) and document them properly.
Cheers,
Nico
PS I am cleaning up my SVN so next time, I can post one patch for all.

> Issue for tracking the progress of the Google Summer of Code project assigned
> to Nicolas Toper. The original project requirements are:
> "Implement a tool for backing up and restoring content in an Apache
> Jackrabbit content repository. In addition to the basic content hierarchies,
> the tool should be able to efficiently manage binary content, node version
> histories, custom node types, and namespace mappings. Incremental or
> selective backups would be a nice addition, but not strictly necessary."
