Fix compatibility test suite (valkey-io#1009)
The compatibility test suite has always relied on manual procedures to generate the answer files (aka pickle files). This has proven inadequate as the current test suite will actually fail if you regenerate the answer files. meaning that test cases were committed to the test suite that weren't actually being tested. This PR does three things. 1. Centralizes the definition of generate modules. This simplifies the addition of new compatibility test suites. 2. Creates a mechanism to ensure that any change to a compatibility test suite will force a regeneration of the answer files. 3. Temporarily comment out failing test cases: Separate PRs will need to be created to fix the newly commented out test cases. --------- Signed-off-by: Allen Samuels <allenss@amazon.com>

To regenerate both compatibility pickle answer files, from the repo root run:

The current handling of the docker instance is flaky, sometimes it needs to be manually killed.
5+
Or, to regenerate just one, cd to this directory and run pytest directly:
6+
7+
pytest generate.py # produces aggregate-answers.pickle.gz
8+
pytest generate_text.py # produces text-search-answers.pickle.gz
9+
10+
Both forms require Docker. The generators spin up redis/redis-stack-server on
11+
port 6380 to capture reference answers; the docker handling is sometimes flaky
12+
and may need to be killed manually between runs.
13+
14+
Each pickle stores a SHA256 of every .py file in this directory. The
15+
compatibility integration test (integration/compatibility_test.py) verifies
16+
that hash on load and fails if it does not match the current sources -- this
17+
forces a regeneration whenever generate.py, generate_text.py, data_sets.py,
18+
text_query_builder.py, or any other source here is edited.
19+
20+
To add a new generator: create generate_xxx.py (subclass BaseCompatibilityTest
21+
with its own ANSWER_FILE_NAME) and add an entry to the GENERATORS list in
22+
__init__.py. regenerate.sh and compatibility_test.py both read from that list.
23+
24+
To bypass the hash check (e.g. when generating a small pickle locally for
25+
quick iteration), set:
26+
27+
SKIP_COMPATIBILITY_HASH_CHECK=1
