[jira] [Created] (SLING-4438) Don't execute duplicate or out-of-order commands

Robert Munteanu created SLING-4438:
--------------------------------------

             Summary: Don't execute duplicate or out-of-order commands
                 Key: SLING-4438
                 URL: https://issues.apache.org/jira/browse/SLING-4438
             Project: Sling
          Issue Type: Bug
          Components: IDE
    Affects Versions: Sling Eclipse IDE 1.0.4
            Reporter: Robert Munteanu
            Priority: Critical
             Fix For: Sling Eclipse IDE 1.1.0


Content sync operations work through commands created on demand by SlingLaunchpadBehaviour.

Right now the order is ad-hoc and there is no guarantee that duplicate or redundant commands are not executed. Some examples:

- Trying to add an sling:Folder resource twice since it seems both the directory and the .content.xml file as changed
- Deleting a path attempts to delete the parent _and_ all children nodes

We also have some akwardness to make sure that SLING-3741 works as expected, see https://svn.apache.org/r1660881 .

The fix would be to have generate the commands, pass them to a provider-specific command queue, which insures that the above cases are handled as expected and then execute the commands in the order returned by the queue.
