If not already the behavior (I don't recall at the moment) the validation could occur only when the block is read (so a file opened with lazy_load=True and corrupt data would not raise an error until the corrupt array data is accessed). This may require some changes to how validate_checksum behaves and documentation updates. Depending on the impact of the change a deprecation period could be considered.
Description of the problem
To address issues of data corruption (like the pre-commit whitespace stripping that held up: https://github.com/spacetelescope/romancal/pull/1161) investigate enabling
validate_checksumas defaultTrue.If not already the behavior (I don't recall at the moment) the validation could occur only when the block is read (so a file opened with
lazy_load=Trueand corrupt data would not raise an error until the corrupt array data is accessed). This may require some changes to howvalidate_checksumbehaves and documentation updates. Depending on the impact of the change a deprecation period could be considered.
