Took a brief look at the PR and it looks good, one think that popped up is to extend the tests and make them follow existing testing pattern
For example use parameterized test to cover both RESP2/RESP3 and also cover UnifiedJedis, JedisCluster and JedisPooled
- For Jedis client streams related test we already have
redis.clients.jedis.commands.jedis.StreamsCommandsTest - For UnifiedJedis you can take a look as example at
src/test/java/redis/clients/jedis/commands/unified/BinaryValuesCommandsTestBase.javaand relatedClusterBinaryValuesCommandsTest,PooledBinaryValuesCommandsTest. Following similar structure for stream commands will test also in cluster&pooled setup

One more thing I forgot: we are planning a mass reformat at some point and will enforce common formatting rules. But for now, please only format the code that has changed, since formatting the entire file makes code reviews harder.
…sequence test (redis#3566) - Refactor StreamsBinaryCommandsTest: replace Map.Entry<byte[], byte[]> with Map.Entry<byte[], StreamEntryID> for xreadBinary, xreadBinaryAsMap, xreadGroupBinary and related methods - Update tests to assert on StreamEntryBinary IDs and byte-array payloads accordingly - Add a new test case covering an illegal UTF-8 sequence (0xc3 0x28) to validate correct binary handling (issue redis#3566)

Hello @ggivo, As you suggested, during the process of writing the duplicated tests, changing the existing public final CommandObject<List<Map.Entry<byte[], List<StreamEntryBinary>>>> xreadBinary(
XReadParams xReadParams,
Map<byte[], StreamEntryID> streams
)(in Apart from replacing calls to Thank you for your valuable guidance and review. |
- Implemented a new JedisByteMap<T> class similar to the existing JedisByteHashMap to properly handle byte array keys in Map<byte[], T> operations - This implementation ensures that `get(byte[])` operations work correctly by using proper byte array equality comparison instead of reference comparison - Fixes issues when using byte arrays as keys in stream-related operations
- Added tests for JedisByteMap similar to existing JedisByteHashMap tests

@YoHanKi Hey, thanks for the update. Will take a look at it later today/tomorrow! |

…ashMap (redis#3566) - Changed Map<byte[], byte[]> in STREAM_ENTRY_BINARY_LIST to JedisByteHashMap.

Hello, @ggivo |
Looks like flaky tests unrelated to your change. I have opened a dedicated issue to investigate the flaky tests & rerun 7.2 job and now it passed. Let me check the other one |
There is already discrepancy in API between `xread` binary variant & `xread` string one. Binary one accepts varargs for requested streams, while the string variant expects them to be provided as `Map`. Going forward xread binary methods should use Map. This commit also marks existing `List<Object> xread` one as deprecated in favor of newly introduced methods for type safety and better stream entry parsing.

Hello @ggivo Thank you for taking the time to review this despite your busy schedule. Is there anything I need to verify or address regarding this issue? |
|
@YoHanKi Meantime started reviewing your latest change. Unfortunately have some other tasks to complete today, and will continue tomorrow. Thanks for spending time on this! |
* Deprecate List<Object> xreadXXX in favor of newly introduced typed methods
Added tests to cover Pipeline command executions. UnifiedJedis BinaryStreamsCommand test clean up and attempt to simplify focused on testing xreadBinary and xreadGroupBinary methods .
* Merged & refactored a bit Jedis BinaryStreamEntryTest.java & StreamsBinaryCommandsTest to match UnifiedJedis StreamsBinaryCommandsTestBase.
