Subject [jira] [Resolved] (DIRSERVER-1357) NullPointerException when deleting alias
Date Fri, 10 Jun 2011 13:22:59 GMT

     [ https://issues.apache.org/jira/browse/DIRSERVER-1357?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Emmanuel Lecharny resolved DIRSERVER-1357.
------------------------------------------

    Resolution: Fixed

Seems that it's not anymore a problem. Added two tests to demonstrate that the deletion of
the entry before the alias works :
http://svn.apache.org/viewvc?rev=1134310&view=rev

Note that the revert operation still fails, so the changeLog interceptor is disabled

> There is a NPE when deleting an alias entry is some special case. Here is a example DIT:
> ou=system
>    |--ou=sales
>    |    |--cn=foo  <--real entry
>    |--ou=engineering
>         |--cn=foo  <--alias, pointing to the real entry
> When I first delete the real entry and afterwards the alias the server throws an exception,
when it cleans the oneAliasIdx and subAliasIdx in the JdbmStore. Note, the exception does
not occur if the real entry and alias are direct descendants of the context entry, because
in that case the oneAliasIdx and subAliasIdx are not used.
