feat: optional checksum algorithm for upload #13849

wuuxigh · 2024-09-24T23:46:23Z

Description of changes

Added optional checksumAlgorithm option for uploadData API to enable CRC-32 checksum calculation.
CRC-32 now works within react native environment upon enablement with this new option.
Upload cache key now includes a UploadDataOptions CRC-32 hash to avoid collision.

Issue #, if available

Description of how you validated changes

Updated unit tests utilizing the checksumAlgorithm option for CRC-32.
Local run of react native e2e test.

Thank you for making this change 👍 @wuuxigh it does fix a sharp edge with current implementation.

On the other hand, we are going to add an option to disable this upload caching feature completely. Partially because of this sharp edge, and there are more sharp edges. We plan to have a more thorough refactor to how we cache the uploads.

For now I think this change is OK to be merged in, even though it will not be used by StorageBrowser.

Ack, when that other change goes in we'll probably need to go through and make optionsHash optional on interfaces.

Sanity check: do we have special error message for client-side hashing errors?

No new error messages were added in this PR.

+ /**

I think the decription is a bit verbose since integrity check means to verify that the data received is the same data that was originally sent.

Suggested change

/**

* This checksum can be used as a data integrity check to verify that the data received is the same data that was originally sent.

/**

Ditto, move this to own file.

Sanity check: What will happen here for any ongoing uploads when this change is released? Is the change backwards compatible?

It will not be backwards compatible and in progress uploads will need to start from scratch.

To build on what Allan suggested, I'd make it even less verbose:

Suggested change

/**

* This checksum can be used as a data integrity check to verify that the data received is the same data that was originally sent.

* @default undefined

/**

+ offset += crc32Hash.length;
+ }
+
+ return `${(await calculateContentCRC32(combinedArray.buffer)).checksum}-${crc32List.length}`;


Probably a stupid question, but why is the length appended to the hash?

Length is needed to indicate that this is a combined checksum expected by s3.

Looks good to me!
