SchemaCompatibility.Compatible has one differ from apache/avro java implementation about avro HOT 2 CLOSED

Hi. Thanks for bringing this up. You can confirm all checks pass with this one change?

Out of interest, how are you running the compatibility tests?

from avro.

Out of interest, how are you running the compatibility tests?

I've took java apache/avro compatibility tests, made from them testcases for golang, and run them. Some part was easy to rewrite by hands, some part by regexps. Of course, I couldn't make full-fledged transpilation - i've had only several days, so hand-rewrite + regexps: made the deal.

Actually, I have now golang tool who take TestSchemaCompatibility.java & TestSchemas.java - and generates golang tests from them. But result code look ugly, so I didn't think somebody will be interested in that (I've just put it into my CI for myself). But if you are interested in that tests generator - I can share it.

yeah, if this check improve - then from java project apache/avro passed next tests:

• https://github.com/apache/avro/blob/main/lang/java/avro/src/test/java/org/apache/avro/TestSchemaCompatibilityFixedSizeMismatch.java#L34 - whole class TestSchemaCompatibilityFixedSizeMismatch
• https://github.com/apache/avro/blob/main/lang/java/avro/src/test/java/org/apache/avro/TestSchemaCompatibilityMissingEnumSymbols.java#L33 - whole class TestSchemaCompatibilityFixedSizeMismatch
• https://github.com/apache/avro/blob/main/lang/java/avro/src/test/java/org/apache/avro/TestSchemaCompatibilityNameMismatch.java - whole class TestSchemaCompatibilityNameMismatch
• https://github.com/apache/avro/blob/main/lang/java/avro/src/test/java/org/apache/avro/TestSchemaCompatibility.java - tests:
  • readerWriterCompatibility()
