[~rskraba] I think allowing the behaviour when generating defaults is enough.
But would you elaborate more on
{quote}For my point #2 above (with Age going in, but Map coming out), maybe
it's enough to just have this clearly documented on the JsonProperties
interface.

[~rskraba] My use case is: I want to extract default values for fields. Please
see my story here: [https://github.com/anhldbk/avro-fork]
For the time being, the code below throws exceptions:
{code:java}
import org.apache.avro.Schema;
import org.apache.avro.reflect.ReflectData;
public class AvroPlay {
public static class Age{
public int value = 9;
}
public static class Person{
public String name = "Andy";
public Age age = new Age();
}
public static void main(String[] args) {
ReflectData reflector = new ReflectData().setDefaultsGenerated(true);
Schema schema = reflector.getSchema(Person.class);
System.out.println(schema.toString(true));
}
}
{code}
When I run it, I've got an exception of:
{noformat}
Exception in thread "main" org.apache.avro.AvroRuntimeException: Unknown datum
class: class org.example.AvroPlay$Age
at
org.apache.avro.util.internal.JacksonUtils.toJson(JacksonUtils.java:96)
at
org.apache.avro.util.internal.JacksonUtils.toJsonNode(JacksonUtils.java:53)
at org.apache.avro.Schema$Field.(Schema.java:581)
at
org.apache.avro.reflect.ReflectData.createSchema(ReflectData.java:747)

org.apache.avro.specific.SpecificData$3.computeValue(SpecificData.java:328)

at
org.apache.avro.specific.SpecificData.getSchema(SpecificData.java:339)
at org.example.AvroPlay.main(AvroPlay.java:18)
{noformat}
So is it reasonable to modify the behavior of
`JacksonUtils.toJson(JacksonUtils.java:96)` a little bit?

[~zolyfarkas] [~rskraba] I think there are 2 other options:
* Opt #1. Introduce Schema.exist(key) to verify if a key is valid, no change
to Schema.get(key)
* Opt #2. Introduce a more consistent way in Schema.fetch(key) and mark
Schema.get(key) as deprecated.

Fine for me. The question is: should we customize the exception to display a
more meaningful message to users?

> Unions are currently anonymous. However it might be convenient if they were
> named. In particular:
> - when code is generated for a union, a class could be generated that
> includes an enum indicating which branch of the union is taken, e.g., a union
> of string and int named Foo might cause a Java class like {code}
> public class Foo {
> public static enum Type {STRING, INT};
> private Type type;
> private Object datum;
> public Type getType();
> public String getString() { if (type==STRING) return (String)datum; else
> throw ... }
> public void setString(String s) { type = STRING; datum = s; }
>
> }
> {code} Then Java applications can easily use a switch statement to process
> union values rather than using instanceof.
> - when using reflection, an abstract class with a set of concrete
> implementations can be represented as a union (AVRO-241). However, if one
> wishes to create an array one must know the name of the base class, which is
> not represented in the Avro schema. One approach would be to add an
> annotation to the reflected array schema (AVRO-242) noting the base class.
> But if the union itself were named, that could name the base class. This
> would also make reflected protocol interfaces more consise, since the base
> class name could be used in parameters return types and fields.
> - Generalizing the above: Avro lacks class inheritance, unions are a way to
> model inheritance, and this model is more useful if the union is named.
> This would be an incompatible change to schemas. If we go this way, we
> should probably rename 1.3 to 2.0. Note that AVRO-160 proposes an
> incompatible change to data file formats, which may also force a major
> release.

No actually. But the developer experience is much better (nice to have)

May be. (Although I ran `mvn test` successfully). I suggest we should gather
RFC for Avro 2.x to include this feature.

[~pcless] Your example code contain errors. I decided to wrap your logic inside
a test
{code:java}
public static class Definition {
public Map tokens;
}
public enum Type {
A,
B,
C
}
@Test
public void testAvro2805() {
Schema schema = ReflectData.get().getSchema(Definition.class);
final String schemaString = schema.toString(true);
System.out.println(schemaString);
}
{code}
I can NOT see your exception above. I've got this one instead:
{noformat}
org.apache.avro.SchemaParseException: Illegal character in: this$0
at org.apache.avro.Schema.validateName(Schema.java:1530)

{noformat}

> Is it incompatible enough to worry about?
Do you think our current tests are enough to validate compatibility? On our
mailing lists, I see so many concerns about backward compatibility. Do you
think we need to make breaking changes with Avro 2.x ?

[jira] [Created] (AVRO-2778) Java: Reflect raises exceptions while dealing with non-static classes

Summary: Java: Reflect raises exceptions while dealing with
non-static classes
Key: AVRO-2778
URL: https://issues.apache.org/jira/browse/AVRO-2778
Project: Apache Avro
Issue Type: Bug
Components: java
Affects Versions: 1.9.2
Reporter: Andy Le
Hi guys,
I've got the following simple code:
{code:java}
public class TestReflect {
public class Human{
String name = "Andy";
}
@Test
public void testNonStaticClasses(){
ReflectData.get().getSchema(Human.class) ;
}
}
{code}
When I run the test, an exception is spawn:
{noformat}

It seems to me that: Avro Reflect does NOT effectively handle non-static
classes.
Should I make a PR against this issue?

I also think we should refactor JacksonUtils to clean it a little bit.
For example, currently we have:
{code:java}
public static Object toObject(JsonNode jsonNode, Schema schema) {
if (schema != null && schema.getType().equals(Schema.Type.UNION)) {
return toObject(jsonNode, schema.getTypes().get(0));
}
if (jsonNode == null) {
return null;
} else if (jsonNode.isNull()) {
return JsonProperties.NULL_VALUE;
} else if (jsonNode.isBoolean()) {
return jsonNode.asBoolean();
}
//. ..
}
{code}
We can have a better code the above:
{code:java}
public static Object toObject(JsonNode jsonNode, Schema schema) {
if (schema != null && schema.getType().equals(Schema.Type.UNION)) {
return toObject(jsonNode, schema.getTypes().get(0));
}
if (jsonNode == null) {
return null;
}
if (jsonNode.isNull()) {
return JsonProperties.NULL_VALUE;
}
if (jsonNode.isBoolean()) {
return jsonNode.asBoolean();
}
// ..
}
{code}
[~sekikn] do you think it's worth to refactor such code?

Another problem is: currently JacksonUtils does NOT handle Short and Byte (see
[this
code|https://github.com/apache/avro/blob/master/lang/java/avro/src/main/java/org/apache/avro/util/internal/JacksonUtils.java#L82-L84]).
So I'm thinking of creating a PR to address them all.

[~rskraba] [~sekikn] I follow [this
guideline|https://cwiki.apache.org/confluence/display/AVRO/How+To+Contribute]
to contribute code. But when I issue commmand
{code:bash}
$ mvn javadoc:aggregate
{code}
I see various errors in other classes (not ReflectData). What should I do? Make
another PR to improve the documentation, right?

[~rskraba] [~sekikn] Currently we have class `ReflectData.AllowNulls` declared
[at line
#175|https://github.com/apache/avro/blob/791ec6017b03e3cc79fbf546dd9d79d20d476b4e/lang/java/avro/src/main/java/org/apache/avro/reflect/ReflectData.java#L75].
Regarding this issue, should I add implementation for
`ReflectData.AllowDefaults` (please see class DefaultReflector above) ?

[~rskraba] Hi. Would you please tell me how to resolve this issue? Any
recommendation? I'm thinking of creating a PR to address this issue. But I
think we need a proper discussion first.
