----------------------------------------
Summary: dfdlx:repType's incorrect handling of Binary Long to
String enumerations
Key: DAFFODIL-2738
URL: https://issues.apache.org/jira/browse/DAFFODIL-2738
Project: Daffodil
Issue Type: Bug
Components: Back End
Affects Versions: 3.3.0
Reporter: Olabusayo Kilo
Fix For: 3.4.0
This is part of a large schema project. So link access to the schema project
will follow in a different comment.
But a short synopsis is when the repType of an element in a binary data format
is an unsignedlong, the repType is ignored in favor of treating the element
like a string type.
For example:
<xs:element name="a" type="tns:jobEnum"/>
<simpleType name="jobEnum" dfdlx:repType="xs:enum4">
<restriction base="xs:string">
<enumeration value="CTO" dfdlx:repValues="1"/>
<enumeration value="MANAGER" dfdlx:repValues="2"/>
<enumeration value="TEAM_LEAD" dfdlx:repValues="3"/>
</restriction>
</simpleType>
<xs:simpleType name="enum4" dfdl:length="4" dfdl:lengthKind="explicit"
dfld:lengthUnit="bits">
<xs:restriction base="xs:unsignedLong"/>
</xs:simpleType>
Would result in the following trace
<Element name='a'><SpecifiedLengthExplicitParser><a
parser='StringOfSpecifiedLengthParser'
/></SpecifiedLengthExplicitParser><AssertExpressionEvaluationParser/></Element>
rather than
<Element name='a'><SpecifiedLengthExplicitParser><a
parser='Binary*SpecifiedLengthParser'
/></SpecifiedLengthExplicitParser><AssertExpressionEvaluationParser/></Element>
Unfortunately the workaround mentioned in
https://issues.apache.org/jira/browse/DAFFODIL-2596?focusedCommentId=17475017&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17475017,
won't work for our usecase because the data is binary and has no delimiters.
