fix: edge cases around mismatched path in json code (#3609) 
For legacy mode:
1. For mutate commands, an empty result should throw an error
2. For read commands, it returns nil if path was not found, but if it was matched
   but only with a wrong types, it will throw an error.

For non-legacy mode, objlen should throw an error for non existing key.

Simplified JsonCallbackResult a bit and made sure more fakeredis tests are passing.

Running FakeRedis tests on Dragonfly

FakeRedis is a Python library that provides a full implementation of the Redis protocol. It is useful for testing Redis clients and for running Redis commands in Python code without having a running Redis server.

The tests in this directory are running against FakeRedis and against a dragonfly instance. The results are then compared to ensure that the two implementations are consistent.

Prerequisites

  • Python 3.10 or above is required to run the tests.
  • Poetry is required to install the dependencies.
  • A dragonfly instance running on port 6380.

Setup environment

  1. Install Poetry by following the instructions at https://python-poetry.org/docs/#installation.
  2. From the root directory of the tests (dragonfly/tests/fakeredis) run poetry env use python3.10 (or higher) to create a virtual environment for Python 3.10.
  3. Run poetry install to install the dependencies.
  4. Run poetry run pytest -v to run all the tests.
  5. Or alternatively, run poetry run pytest -v test/{test-name} to run a specific set of tests.

Tests

  • test_connection.py: Tests for the connection parameters to the Dragonfly server.
  • test_zadd.py: Considering the various options for the ZADD command, it has its own set of tests.
  • test_json/*.py: Tests for the JSON commands.
  • test_stack/*.py: Tests for the stack commands, bloom filter, cuckoo filter, CMS, TDigest, time-series, top-k.
  • test_mixins/*.py: Tests for various generic commands: bitmap, geospacial, hash, list, pubsub, scripting, streams, string, etc.
  • test_hypothesis.py: Hypothesis tests for the mixins commands. These tests are using hypothesis and generate random tests with edge cases. Note these tests take significantly more time to run.

General info

  • @pytest.mark.unsupported_server_types("dragonfly") decorator indicates to pytest that the test should not run on dragonfly.
    • Some tests are skipped the commands are CURRENTLY not supported (e.g., GEORARIUS).
    • Others are skipped because they cause an expected behavior, and usually marked with TODO comment as well.
