[jira] [Created] (OAK-102) Expose the branch feature from NodeStore
Jukka Zitting created OAK-102:
---------------------------------
Summary: Expose the branch feature from NodeStore
Key: OAK-102
URL: https://issues.apache.org/jira/browse/OAK-102
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Reporter: Jukka Zitting
As discussed on oak-dev@, the current NodeStateBuilder implementation in .oak.kernel is complicated by the fact that it needs to maintain a fairly complicated mapping between the uncommitted transient state kept in the builder context and the underlying persisted/branched state of the content tree.
To avoid such complications, we should expose the branch feature and allow especially copy and move operations to be performed directly against a branch
instead of indirectly through the NodeStateBuilder interface.

[jira] [Commented] (OAK-102) Expose the branch feature from
NodeStore

Michael Dürig commented on OAK-102:
-----------------------------------
I committed an initial implementation at revision 1339630. Some things still need to be further refined:
* Commit hooks are not called yet on NodeStoreBranch.merge(). I will resolve this in context of OAK-100.
* A rebase operation should take place on NodeStoreBranch.merge(). I will resolve this in context of OAK-100.
* MemoryNodeStateBuilder could probably be replaced with some more lightweight mechanism. Will investigate and open a separate issue if necessary.
