CompleteMultipartUpload - can it return error on 200 OK like S3 can?

🟧AWS SDK❓Question

So it turns out that S3 can theoretically return a 200 OK for a CompleteMultipartUpload call, but still return an error in the body, which is insane, but here we are: https://docs.aws.amazon.com/AmazonS3/latest/API/API_CompleteMultipartUpload.html

Does Tigris have this same behavior? I guess in general, should I always be parsing the XML responses from S3 calls to look for errors, or can I rely on a 200 OK meaning we have successfully completed the request?

CompleteMultipartUpload - Amazon Simple Storage Service

Completes a multipart upload by assembling previously uploaded parts.

Solution

@spicy_heck_boi you can rely on 200, it should be safe to assume at that point that object is uploaded.

In general you should be able to rely on 200 OK to mean success.

Which SDK are you using?

In this particular case I'm just making raw HTTP requests, the SDKs were a bit heavyweight for like the 5 functions I need.

But via the S3 compatible endpoints

Perfect, thank you for making the handling better than S3's
