> C# ToParsingForm normalizes logical type to "logical" rather than base type
> ---------------------------------------------------------------------------
>
> Key: AVRO-3568
> URL: https://issues.apache.org/jira/browse/AVRO-3568
> Project: Apache Avro
> Issue Type: Bug
> Components: csharp, logical types
> Affects Versions: 1.11.0
> Reporter: Kalle Niemitalo
> Assignee: Robert Yokota
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.12.0
>
>
> In the Avro C# library, if Avro.SchemaNormalization.ToParsingForm(Schema) is
> given a schema that includes a logical type, then it normalizes that just to
> "logical" and not to the base type. The resulting JSON cannot even be parsed
> by Avro.Schema.Parse(string). This also makes
> SchemaNormalization.ParsingFingerprint return an incorrect fingerprint for
> schemas that include logical types.
> h2. To reproduce
> {code:C#}
> using System;
> class Program
> {
> static void Main()
> {
> var schema = Avro.Schema.Parse(
> @"[""int"", {""type"": ""string"", ""logicalType"": ""uuid""}]");
> string pcf = Avro.SchemaNormalization.ToParsingForm(schema);
> Console.WriteLine(pcf);
> Avro.Schema.Parse(pcf);
> }
> }
> {code}
> h2. Expected result
> {noformat}
> ["int","string"]
> {noformat}
> h2. Actual result
> {noformat}
> ["int","logical"]
> Unhandled exception. Avro.SchemaParseException: Undefined name: logical at
> '[1]'
> at Avro.Schema.ParseJson(JToken jtok, SchemaNames names, String encspace)
> at Avro.UnionSchema.NewInstance(JArray jarr, PropertyMap props,
> SchemaNames names, String encspace)
> at Avro.Schema.ParseJson(JToken jtok, SchemaNames names, String encspace)
> at Avro.Schema.Parse(String json, SchemaNames names, String encspace)
> at Avro.Schema.Parse(String json)
