Mike Beckerle updated DAFFODIL-2171:
------------------------------------
Component/s: DFDL Language
> Delimiter scanning takes into account too many delimiters
> ---------------------------------------------------------
>
> Key: DAFFODIL-2171
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2171
> Project: Daffodil
> Issue Type: Bug
> Components: Back End, DFDL Language
> Affects Versions: 2.4.0
> Reporter: Steve Lawrence
> Assignee: Mike Beckerle
> Priority: Major
>
> When scanning for delimiters, we can sometimes scan for delimiters that we
> shouldn't. See test {{delmiterScanning_03}} in
> {{SequenceGroupDelimiters.tdml}} as an example where we scan for comma
> separator that, while it is in scope, should be ignored because the element
> is the last in the sequence with an infix separator.
> I've confirmed that the DelimitedStringParser scans for and finds the wrong
> delimiter, but it's possible that this is a problem in the delimiter stack.
> Perhaps we need to manipulate the delimiter stack when we determine that the
> current scope of delimiters should be ignored due to being the last in the
> sequence? With the correct stack, all the delimiter scanning and delimite
> consuming sould just work.
