Dmitry S	9d4eeda480	(core) Python optimizations to speed up data engine ... Summary: - A bunch of optimizations guided by python profiling (esp. py-spy) - Big one is optimizing Record/RecordSet attribute access - Adds tracemalloc printout when running test_replay with PYTHONTRACEMALLOC=1 (on PY3) (but memory size is barely affected by these changes) - Testing with RECORD_SANDBOX_BUFFERS_DIR, loading and calculating a particular very large doc (CRM), time taken improved from 73.9s to 54.8s (26% faster) Test Plan: No behavior changes intended; relying on existing tests to verify that.

Alex Hall	84ddbc448b	(core) Add test_replay for easily replaying data sent to the sandbox purely within python ... Summary: Run JS with a value for SANDBOX_BUFFERS_DIR, then run test_replay in python with the same value to replay just the python code. See test_replay.py for more info. Test Plan: Record some data, e.g. `SANDBOX_BUFFERS_DIR=manual npm start` or `SANDBOX_BUFFERS_DIR=server ./test/testrun.sh server`. Then run `SANDBOX_BUFFERS_DIR=server python -m unittest test_replay` from within `core/sandbox/grist` to replay the input from the JS. Sample of the output will look like this: ``` Checking /tmp/sandbox_buffers/server/2021-06-16T15:13:59.958Z True Checking /tmp/sandbox_buffers/server/2021-06-16T15:16:37.170Z True Checking /tmp/sandbox_buffers/server/2021-06-16T15:14:22.378Z True ``` Reviewers: paulfitz, dsagal Reviewed By: dsagal Differential Revision: https://phab.getgrist.com/D2866	3 years ago
