AVRO-2432: Handle Empty Datafiles (#691)
> Python 3: AssertionError on reading "empty" file
> ------------------------------------------------
>
> Key: AVRO-2432
> URL: https://issues.apache.org/jira/browse/AVRO-2432
> Project: Apache Avro
> Issue Type: Bug
> Components: python
> Affects Versions: 1.9.0
> Reporter: David Beswick
> Assignee: Michael A. Smith
> Priority: Minor
> Fix For: 1.10.0
>
> Attachments: 28.avro, patch-avro-2432.patch
>
>
> I've seen this problem with the pip package avro-python3. An AssertionError
> is thrown on reading certain unusual files.
> Problematic files seem to have these characteristics:
> * The file is read without issue by avro-tools
> * Normal, correct header with sync token
> * Zero records (first block_count read is zero)
> * A sync token follows the zero block_count long, then EOF
> An example file is attached.
> Repro code (nothing special):
> {code:python}
> from avro.datafile import DataFileReader
> from avro.io import DatumReader
> with DataFileReader(open("28.avro", 'rb'), DatumReader()) as r:
> for rec in r:
> print(rec)
> {code}
