Subject [jira] Commented: (DIRSERVER-1020) FilterParser can become inconsistent under certain circumstances: needs rewrite
Date Mon, 24 Sep 2007 13:36:50 GMT

    [ https://issues.apache.org/jira/browse/DIRSERVER-1020?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12529858
] 

Emmanuel Lecharny commented on DIRSERVER-1020:
----------------------------------------------

I have found a way to reproduce this problem. As I was trying to create some new Search test
which was using an open server for the whole tests, the filter parser is never reinitialized.
I found a failing tests where we send this filter (cn=*o* *o*) which translated to (cn=*o*o*)
while it should be (*o**o*) (because of the internal space).

I will see how to fix the parser.

> I had trouble reproducing this bug in it's entirity but I think a serious rewrite by
a antlr pro like seelmann is needed.  If seelmann could make this parser as healthy as the
others he has written I think we can get rid of this issue which results from a poorly written
antlr parser implementation for filter expression parsing.
