Emmanuel Lecharny commented on DIRSERVER-1974:
----------------------------------------------
For some (yet) unknown reason, the {{piarCache}} (Parent ID And Rdn cache) used
in the {{AbstractBTreePartition.buildEntryDn()}} method still has the wrong
{{RDN}} associated with the renamed entry's UUID. The Entry's DN is rebuilt
using this info and that causes the issue we have.
I can't explain why this cache contains this (old) value after a call to the
{{rename}} operation, not why it's not there anymore if I add a 100ms sleep in
the loop...
The {{piarCache}} can contain 10 000 elements and last 20 mins. Way more than
what we need in this test (it contains 803 elements)
> Rename Operation Issue - ApacheDS
> ---------------------------------
>
> Key: DIRSERVER-1974
> URL: https://issues.apache.org/jira/browse/DIRSERVER-1974
> Project: Directory ApacheDS
> Issue Type: Bug
> Components: jdbm, ldap
> Affects Versions: 2.0.0-M15
> Environment: Window server 2008 R2
> Reporter: Mohd Usman
> Priority: Blocker
> Labels: build, features, patch
> Attachments: ApacheDSSchemaBrowser.png, CNAttributeInSchema.png,

> Original Estimate: 168h
> Remaining Estimate: 168h
>
> Whenever we perform Rename operation on an object entry (let’s say Person
> object), the person gets renamed successfully but the issue is that the old
> value of the person object still remains.
> The ‘cn’ attribute contains two values now - old value and also the new value.
>
> Example:
> I have created a person object with DN
> "cn=person,ou=Apache,dc=example,dc=com" and I want to rename this entry to
> "cn=person_Rename,ou=Apache,dc=example,dc=com".
> The rename operation executes successfully and the person is renamed to
> "cn=person_Rename,ou=Apache,dc=example,dc=com".
> But, the ‘cn’ attribute now contains
> “person”
> “person_Rename”.
> When verified the schema, ‘cn’ attribute show as ‘single valued’ but after
> performing the rename operation – the ‘cn’ becomes ‘multi-valued’ and
> contains two values.
> This an issue with Apache directory which needs to be resolved. Also find the
> screenshots attached for your reference. Please look into the same.
