Kousuke Saruta updated AVRO-3825:
---------------------------------
Summary: Disallow invalid namespaces (was: Disallow invalid namespace)
> Disallow invalid namespaces
> ---------------------------
>
> Key: AVRO-3825
> URL: https://issues.apache.org/jira/browse/AVRO-3825
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.12.0
> Reporter: Kousuke Saruta
> Priority: Major
>
> According to the specification, each portion of a namespace separated by dot
> should be [a-z,A-Z,_][a-z,A-Z,0-9_].
> [https://avro.apache.org/docs/1.11.1/specification/#names]
> {code:java}
> The name portion of the fullname of named types, record field names, and enum
> symbols must:
> start with [A-Za-z_]
> subsequently contain only [A-Za-z0-9_]
> A namespace is a dot-separated sequence of such names. The empty string may
> also be used as a namespace to indicate the null namespace. Equality of names
> (including field names and enum symbols) as well as fullnames is
> case-sensitive.
> The null namespace may not be used in a dot-separated sequence of names. So
> the grammar for a namespace is:
> <empty> | <name>[(<dot><name>)*]
> {code}
