Dear avro developers, I would like to contribute to the avro project. I have identified a bug in the Rust implementation of GenericSingleObjectReader::read_value <https://docs.rs/apache-avro/0.14.0/apache_avro/struct.GenericSingleObjectReader.html#method.read_value>, which is exposed when a call to reader.read reads less than 10 bytes. This is a valid scenario, as according to the documentation of Read::read <https://doc.rust-lang.org/std/io/trait.Read.html#tymethod.read>, "It is not an error if the returned value n is smaller than the buffer size, even when the reader is not at the end of the stream yet." This is also a real-life scenario: in my use-case, I am chaining three implementations of the Read trait to messages that can be deserialized (one for the two magic bytes, one for the schema fingerprint, and one for the actual message content). Each call to Read::read only returns the bytes of one chain link, so the first call to Read::read only returns 2 bytes. I have forked the repository, and wrote a test that exposes the bug (commit https://github.com/davidpeklak/avro/commit/128e2a52e8d22c39aa24ba574523883777a85c76), and a fix for the bug (commit https://github.com/davidpeklak/avro/commit/6f7bc050e0454733a9dbd6835f2cd4bd49f390e1), by calling Read::read_exact <https://doc.rust-lang.org/std/io/trait.Read.html#method.read_exact> instead of Read::read <https://doc.rust-lang.org/std/io/trait.Read.html#tymethod.read>.
I would need help to understand how to proceed from here please. I have noticed that all pull-requests refer to tickets in Jira <https://issues.apache.org/jira/browse/AVRO-3639?jql=project%20%3D%20AVRO%20AND%20component%20%3D%20rust>, but I do not know how to get permission to create a Jira ticket. What should be my next steps? Kind regards, David Peklak
