[jira] Updated: (DIRLDAP-38) Search request BER parser incorrectly parses complex filters.

     [ http://issues.apache.org/jira/browse/DIRLDAP-38?page=history ]

Alex Karasulu updated DIRLDAP-38:
---------------------------------

       Priority: Blocker  (was: Major)
    Fix Version: 0.9.0

Have not had the time yet to look at this one but if you're right this is really serious.  We cannot release 0.9 without it.  Can you attach a patch with a test case showing this bug in effect?  If you are printing it out into a string it might be the visitor that prints out the info or the normalizing visitor that is causing this.  The normalizing visitor tries to rearrange the AST for the filter so terms in the same nesting level are in the same cannonical order when printed out - this is done to be able to compare filter expressions.

> Using the following search from an LDAP client, like Softera's browser or OpenLDAP's ldapsearch, search for something like the following filter:
> (& (a=A) (| (b=B) (c=C) ) )
> The resulting expression object after the BER parser is finished is:
> (& (| (c=C) (b=B) (a=A) ) )
> This is obviously not the correct expression and results in bobus results.
> I thought at first it might have been the expression object serializing to a string form that had issue, but passing the same filter string through the commons.filter.FilterParserImpl produces the correct expression object and the correct serialized string.
> I am attempting to debug the problem further.  If I can produce a patch I will post it, but if someone has a better idea of what is going please tackle this.
