[platform-vcm-dev] Move Delete Hooks problem

[Balaji Krishnamachari-samp <balajik@xxxxxxxxxx>]

All,

I am working on move delete hooks for
a repository provider plug-in. It seems like the navigator view and the
package explorer view handle moving resources differently. 

Let us assume my package structure is
defined as the following: 

Navigator View: 
+ src
  + com
       + ibm
           +
package1
           
         Test1.java
           
         Test2.java
           
         + innerPackage
           
                  Test3.java
 

Package Explorer View:
+ src 
      + com.ibm.package1
           
   Test1.java
           
   Test2.java
      + com.ibm.package1.innerPackage
           
    Test3.java   

If I try to rename the folder package1
inside navigator view, a moveFolder is called on package1 which seems to
make sense. But if we try to rename the package package1 to package2 in
package explorer, the jdt does a real good job of calling the moveFile(Test1.java)
and moveFile(Test2.java) rather than renaming outer and inner package com.ibm.package1.innerPackge.
( This seems to make sense because jdt does not want to rename all the
inner package structures). 

To acomplish the above mentioned scenario,
jdt does the following: 
1. Create a package com.ibm.package2
2. Move the filesTest1.java and Test2.java
from package1 to package2.
3. Since the move did not happen in
the repository, being a pessimistic provider, I cancel the local move operation
after getting the users input on the cancel operation. User had requested
to cancel the operation and hence I set the status to IStatus.OK.
4. Since the source package com.ibm.package1
is not empty, jdt tries to delete the file Test1.java and Test2.java from
com.ibm.package1. ( Interestingly jdt does not check whether the move operation
 was successful or not... Does it mean I need to set the status to
ERROR or error rather than OK to make jdt realize that move delete hooks
were called but the move did not happen ( setting it to INFO does not change
the behavior. setting it to ERROR will abort the operation which I don't
need. I want to provide users with an option to rename all the files under
the package in the repository and if successful want to mirror the operation
locally) ). 

Should the jdt not check the return
codes ( or atleast the existense of the resource in source package ) and
do the operations appropriately. if I cancel my individual renames of all
files and the deletes on all the files, I get a internal error exception
"Resource Test1.java not found in package com.ibm.package2".
The package com.ibm.package2 is not deleted too after the operation is
completed. 

Thanks
