Shaw Young created AVRO-4094:
--------------------------------
Summary: Namespaces not mapped in type references
Key: AVRO-4094
URL: https://issues.apache.org/jira/browse/AVRO-4094
Project: Apache Avro
Issue Type: Bug
Components: csharp
Affects Versions: 1.11.4
Environment: Avrogen is being run against dotnet 8 c# code from the
linux command line.
Reporter: Shaw Young
Given this avsc schema file
{code:java}
[
{
"type": "enum",
"name": "Planets",
"namespace": "myapp.account",
"symbols": [
"EARTH",
"MARS",
"VENUS",
"MERCURY"
],
"doc": "Planets of the solar system"
},
{
"type": "record",
"name": "AccountCreation",
"namespace": "myapp.account",
"doc": "A individual user of the system.",
"fields": [
{
"name": "id",
"type": "string",
"doc": "The unique identifier for the user."
},
{
"name": "name",
"type": [
"null",
"string"
],
"default": null,
"doc": ""
},
{
"name": "homePlanet",
"type": "Planets",
"doc": ""
},
{
"name": "favouritePlanet",
"type": [
"null",
"Planets"
],
"default": null,
"doc": ""
}
]
}
] {code}
and the avrogen with the following parameters;
{code:java}
avrogen -s ./simple.avsc ./out --namespace myapp.account:MyApp.Account{code}
Everything is generated as expected;
{code:java}
out
└── App
└── Account
├── AccountCreation.cs
└── Planets.cs {code}
Now consider a minor alteration of moving Planets into its own common namespace
so it can reused- we still wish to reference it from the AccountCreation entity
by simply adding the namespace to the type;
{code:java}
[
{
"type": "enum",
"name": "Planets",
"namespace": "myapp.common",
"symbols": [
"EARTH",
"MARS",
"VENUS",
"MERCURY"
],
"doc": "Planets of the solar system"
},
{
"type": "record",
"name": "AccountCreation",
"namespace": "myapp.account",
"doc": "A individual user of the system.",
"fields": [
{
"name": "id",
"type": "string",
"doc": "The unique identifier for the user."
},
{
"name": "name",
"type": [
"null",
"string"
],
"default": null,
"doc": ""
},
{
"name": "homePlanet",
"type": "myapp.common.Planets",
"doc": ""
},
{
"name": "favouritePlanet",
"type": [
"null",
"myapp.common.Planets"
],
"default": null,
"doc": ""
}
]
}
] {code}
Including the extra namespace mapping when running avrogen;
{code:java}
avrogen -s ./demo.avsc ./out --namespace myapp.common:App.Common --namespace
myapp.account:MyApp.Account{code}
This run fails
{code:java}
Exception occurred. Undefined name: myapp.common.Planets at
'[1].fields[2].type'{code}
Looking at the code it looks like the preparse step will substitute namespace
attributes using the collection of namespace mapping, but doesn't substitute
any of the type mappings, if they include one of the mapped namespaces.
