Summary
Fixes ingesting
ChannelDataType.BYTESchannels from the Python library, bumpssift-stream-bindingsto 0.5.1 (the Rust side of the change, #782), and preps thev0.21.0release.Reported by a customer on sift-stack-py v0.20.0:
ValueError: Unknown data type: byteswhen registering a flow with a bytes channel.Why
#761 fixed flow registration but is unreleased. The next failure a user hits is sending a value on a bytes channel:
ValueError: Invalid data type: bytesfromChannelValue._to_rust_form. That path neededValuePy.Bytes, which did not exist in the bindings until 0.5.1.Changes
sift_client/sift_types/ingestion.py: handleBYTESinChannelValue._to_rust_form, acceptingbytes,bytearray,memoryview, or an iterable of ints. Also add the missingBYTESandSTRINGbranches to_to_rust_value.pyproject.tomlanduv.lock:sift-stream-bindings==0.5.0→==0.5.1in every extra. The generatedallextra was regenerated withgenerate_extras.pyand matches.TestChannelValuecovers both converters across everyChannelDataType, including the bytes-like input types and theNonepath.version0.20.0→0.21.0inpyproject.tomlanduv.lock.CHANGELOG.mdturns the Unreleased section intov0.21.0 - September 4, 2026, which also carries the unreleased data import listing, enum import, andget_datananosecond warning changes.Verification
Against the published 0.5.1 wheel: ruff,
mypy lib, and the ingestion tests pass. The full non-integration suite passes exceptsift_py/data_import/_csv_test.py::test_simple_upload_invalid_csv, which also fails on a clean checkout of main.After merge
