#690 Code bundling using posix-style paths Pull request opened by cosmicBboy This pull request improves cross-platform compatibility in the Flyte code bundle packaging and hashing logic, with a focus on ensuring consistent behavior between Windows and Unix systems. The main changes guarantee that all file paths used in hashing and tarball creation are normalized to POSIX-style (forward slash) paths, preventing subtle bugs and inconsistencies. Comprehensive tests have also been added to verify these behaviors. Cross-platform path normalization: • Updated

ls_files

and

ls_relative_files

in

src/flyte/_code_bundle/_utils.py

to use POSIX-style paths for hashing, ensuring that file digests are consistent across platforms. [1] [2] • Modified

create_bundle

in

src/flyte/_code_bundle/_packaging.py

to ensure tarball entries always use forward slashes, regardless of the platform or input path style. Testing for cross-platform consistency: • Added extensive tests in

tests/flyte/code_bundle/test_code_bundle.py

to verify: • Hashes generated by

ls_files

and

ls_relative_files

are consistent and use POSIX paths. • Tarball entries created by

create_bundle

always use forward slashes, even when input paths are Windows-style. • Included necessary imports for tarfile and os in the test file. • Updated test imports to directly test the affected functions. flyteorg/flyte-sdk
