Custom/Aliased UADataTypes and UAVariableTypes not supported #253

Open paddor opened 7 months ago

paddor commented 7 months ago

I noticed that UA_findDataTypeWithCustom() can't find the data types of imported UAVariables with custom/aliased UADataTypes.

Given the following namespaces:

  <NamespaceUris>
    <Uri>http://foobar.example.com/Types/v2</Uri>
    <Uri>http://foobar.example.com/Instances</Uri>
  </NamespaceUris>

Given these Aliases:

    <Alias Alias="DataItemType">i=2365</Alias>
    <Alias Alias="AlarmStateStates">ns=1;s=af28ed20-dbb6-5624-aa65-4b42023ab1c4</Alias>
    <Alias Alias="AlarmStateType">ns=1;s=0cde5300-0cef-4699-b5c3-acb5011e0aa3</Alias>

And this UADataType:

  <UADataType NodeId="ns=1;s=af28ed20-dbb6-5624-aa65-4b42023ab1c4" BrowseName="1:AlarmStateStates">
    <DisplayName>AlarmStateStates</DisplayName>
    <Description Locale="de">Alarm- und Fehlerzustände</Description>
    <References>
      <Reference ReferenceType="HasProperty">ns=1;s=91428b80-ccb1-5adb-8685-5d51c867a0d3</Reference>
      <Reference ReferenceType="HasSubtype" IsForward="false">Enumeration</Reference>
    </References>
    <Definition Name="1:AlarmStateStates">
      <Field Name="Inaktiv" Value="0"/>
      <Field Name="Aktiv" Value="1"/>
    </Definition>
  </UADataType>

And this UAVariableType:

  <UAVariableType NodeId="ns=1;s=0cde5300-0cef-4699-b5c3-acb5011e0aa3" BrowseName="1:AlarmStateType" DataType="AlarmStateStates">
    <DisplayName>AlarmStateType</DisplayName>
    <Description Locale="de">Alarm- und Fehlerzustände</Description>
    <References>
      <Reference ReferenceType="HasSubtype" IsForward="false">DataItemType</Reference>
    </References>
  </UAVariableType>

And this UAVariable:

  <UAVariable NodeId="ns=2;g=16001624-6a1d-42d5-81d1-f54af84f5325" BrowseName="1:E_ComState" ParentNodeId="ns=2;g=33b2b39b-57a5-4d9f-af09-ae2f00ae1776" DataType="AlarmStateStates" AccessLevel="1">
    <DisplayName>E_ComState</DisplayName>
    <Description Locale="de">Energiemessung Messzelle Z.X Fehler: Kommunikation</Description>
    <References>
      <Reference ReferenceType="HasComponent" IsForward="false">ns=2;g=33b2b39b-57a5-4d9f-af09-ae2f00ae1776</Reference>
      <Reference ReferenceType="HasTypeDefinition">AlarmStateType</Reference>
    </References>
  </UAVariable>

(Sorry, I can't provide a full XML nodeset right now. But maybe this info is already enough.)

As preparation for UA_Server_writeDataValue(), my code can't find the data type by the type nodeId AlarmStateStates nor the type nodeId ns=2;s=af28ed20-dbb6-5624-aa65-4b42023ab1c4 (adjusted for runtime NS index) using UA_findDataTypeWithCustom(). Any ideas?

paddor commented 7 months ago

Weirdly enough, if I read the data type of an imported variable (that should have dataType=AlarmStatesStates) using UA_Server_readDataType() and UA_findDataType(), I sometimes get no data type or the wrong data type. It's non-deterministic.

I was hoping to use UA_DataType.typeKind to support these custom types but like this I have no path forward. Any ideas?

paddor commented 7 months ago

@matkonnerth Here's a working example in C along with the full XML nodeset. It tries to get the data type of g=16001624-6a1d-42d5-81d1-f54af84f5325, which fails.

@paddor : thank you for the detailled issue report, do you the result with the nodesetcompiler?

paddor commented 7 months ago

@matkonnerth Sorry, I didn't understand the question. The nodeset itself works, in another UA stack and also in this UA stack, at least when checked via UaExpert. What doesn't work is getting the real data type of the variable node.

matkonnerth commented 7 months ago

sry, the open62541 has also the ability to generate c code for the information model (done with the nodesetcompiler). Would be interesting if the issue preserves with that method.

What does this mean?

matkonnerth commented 7 months ago

oh, seems that NodeIds with type ByteString or Guid are not supported by the nodesetcompiler

paddor commented 7 months ago

I've added support for GUID node IDs in a PR: https://github.com/open62541/open62541/pull/6355

The script completes successfully and gives me two files.

It seems the compiled nodeset tries to create the same node twice?

It is always the same: ns=2;g=c99a4933-9ba-456e-89c4-b0ee01003c89 I'm not sure if it has to do with the missing leading zeroes in the GUID.

I've fixed the issue with missing leading zeroes. See https://github.com/open62541/open62541/pull/6355.

The server with the compiled nodeset now imports many more variables before aborting:

If that error message is correct, a default value is missing (originally in the XML nodeset, but here in the compiled nodeset). That would mean the nodesetLoader should complain about the missing default value too, instead of silently importing the nodeset without warnings/errors. Correct?
