v1.29.2

What's Changed

Important Breaking Change

This release includes an important fix to object store which is a breaking change for old JavaScript clients. The sha-256 library previously used, generated incorrect digests for large payloads (512MB or larger). The library has been replaced with npms js-sha256, but any object that exercised the issue sports an incorrect digest. This issue has not been observed with objects smaller than 512MB.

• get the object with a different tool or client.
• or a different tool or client created an object

Since upgrading to this client will calculate hashes differently for the large objects, upgrading will detect objects that previously were correct as corrupt.

Migration Process

• If you don't use object-store you can ignore this process.
• If your objects are well below the 500MB limit, it you can possibly skip the migration step (not recommended).
• If you have large objects that are greater than 500MB you MUST run the migration tool or re-put your objects.

To aid you in migration a new tool is provided that will update hashes that were incorrect and detected to be created by the previous library. Please run this tool on object stores prior to upgrading.
The tool will read all objects in the object store, and calculate a digest using the original (broken sha-256 implementation) and the updated one. If the hashes differ, and the broken digests match, the tool will update the entry's metadata to the correct digest. The tool can run in a check-only mode by providing the --check option.

Note that after updating your object store, old JavaScript clients will detect the large entries as corrupt.
