Todd McDowell created AVRO-4230:
-----------------------------------
Summary: Avro::BinaryEncoder's encode_map generates
non-deterministic output which makes writing unit tests more difficult
Key: AVRO-4230
URL: https://issues.apache.org/jira/browse/AVRO-4230
Project: Apache Avro
Issue Type: Improvement
Components: perl
Affects Versions: 1.12.1
Reporter: Todd McDowell
I was attempting to write unit tests for Perl code that was making use of
Avro::BinaryEncoder. The code was specifically calling encode_map, which
encodes a Perl hash into binary. However, since Perl's keys function does not
guarantee a consistent order of the hash's keys, the expected value from
encode_map occasionally fails to match the observed value, which causes the
test to fail.
I recommend sorting the keys of the data in encode_map before the encoding
process to ensure a deterministic output from encode_map. I've already
modified the code, but I needed to submit this issue before I could submit the
pull request change based on the instructions I read. The deterministic output
from encode_map will make testing simpler. I'll submit that change for review
shortly.
Thanks for your attention.
