--------------------------------------
This test case gives me a compilation warnings. I`ve fixed it in AVRO-1088.patch.2

> Key: AVRO-1088
> URL: https://issues.apache.org/jira/browse/AVRO-1088
> Project: Avro
> Issue Type: Improvement
> Components: c
> Affects Versions: 1.7.0
> Environment: Ubuntu Linux 11.10
> Reporter: Vivek Nadkarni
> Fix For: 1.7.0

> Attachments: AVRO-1088.patch, AVRO-1088.patch.2

> Original Estimate: 24h
> Remaining Estimate: 24h
>
> The current performance test in Avro-C measures the performance while
> reading and writing of Avro values using a complex record schema,
> which does not contain any arrays.
> We add tests to measure the performance for simple and nested
> arrays. We also replicate all tests to measure the performance of the
> schema resolution using a resolved reader and a resolved writer.
> Specifically we add the following performance tests:
> Nested Record
> 1. Replicating the test "nested record value by index", using a helper
> function. Using helper functions adds a little overhead, but it
> allows us to test various schemas, as well as different modes of
> schema resolution much more easily.
> 2. Using a resolved writer to resolve between (identical) reader and
> writer schemas, while reading a complex record.
> 3. Using a resolved reader to resolve between (identical) reader and
> writer schemas, while writing a complex record.
> Simple Array
> 4. Test the performance for reading and writing a simple array.
> 5. Using a resolved writer to resolve between (identical) reader and
> writer schemas, while reading a simple array.
> 6. Using a resolved reader to resolve between (identical) reader and
> writer schemas, while writing a simple array.
> Nested Array
> 7. Test the performance for reading and writing a nested array.
> 8. Using a resolved writer to resolve between (identical) reader and
> writer schemas, while reading a nested array.
> 9. Using a resolved reader to resolve between (identical) reader and
> writer schemas, while writing a nested array.
> Additionally we fix a minor bug:
> 1. The return value of avro_value_equal_fast() was not being
> tested. Test this return value, and fail if it is FALSE.
