Ok, so ethernetIP has no global elements because its test elements are
defined in the TDML files.
It's a schema that just defines global types, and the notion is that schemas
that use eithernetIP, like PCAP, but also some other schemas, they get the job
of defining the elements.
No reason not to change this and add some test elements directly to
ethernetIP however so that it can be debugged directly without need of anything
from the TDML file.
So go ahead and add:
<xs:element name="testRoot">
<xs:complexType>
<xs:sequence>
<xs:element name="Ethernet" type="eth:Ethernet"/>
</xs:sequence>
</xs:complexType>
</xs:element>
You will need to create test data from testEthernet.tdml also. There are no
files of test data in ethernetIP. The test data is all expressed in hex in the
tdml file.
I know I said for sure see if you can debug PCAP/EthernetIP, but.... turns
out you've hit PCAP and ethernetIP in this 3.2.0 release transition currently.
I was in the middle of updating all the various published DFDL schemas to
reference 3.2.0 daffodil, and update other libraries, etc. when we found the
daffodil 3.2.0 release has a bad unparser bug that is preventing ethernetIP and
hence PCAP from working with checksum calculations, which are a primary feature
3.2.0 was supposed to enable.
Suggest you back out to the prior tagged release of ethernetIP (tag 1.0.0),
and prior git hash for PCAP the ghit hash you want is one back from the current
master branch head, so git hash 87b4b28cc56a8ce9383af2f52711182a87013a3c.
Or do git checkout master; git checkout HEAD^
I just did this and it worked:
cd dfdl-ethernet # where I have ethernetIP cloned
git checkout 1.0.0
sbt test
sbt publishLocal
cd ../dfdl-pcap
git checkout master
git checkout HEAD^
sbt test
All tests pass, so at this point you should be able to debug PCAP on some of
its data files which are under src/test/resources/com/tresys/pcap/data.
