Subject [jira] [Created] (AVRO-1364) Avro-C reader ignores final block in file
Date Wed, 21 Aug 2013 13:29:52 GMT
Ben Walsh created AVRO-1364:
-------------------------------

             Summary: Avro-C reader ignores final block in file
                 Key: AVRO-1364
                 URL: https://issues.apache.org/jira/browse/AVRO-1364
             Project: Avro
          Issue Type: Bug
          Components: c
    Affects Versions: 1.7.5
            Reporter: Ben Walsh


The Avro-C reader can ignore the final block(s) in a file. It buffers the final block(s) to
memory then detects EOF and returns. It doesn't finish reading from the buffer before returning
EOF.

This bug was introduced in AVRO-1238 (https://issues.apache.org/jira/browse/AVRO-1238).

To reproduce:

$ cd avro/lang/c/tests

# copy file with 1 block
$ cp avro-1238-good.avro two-blocks.avro

# copy block to make file with 2 blocks
$ xxd -c1 -p avro-1238-good.avro | tail -22 | xxd -r -p >>two-blocks.avro

# should return 2*2 = 4 records:
$ ../build/src/avrocat two-blocks.avro 
null
{"int": 100}
