s3 upload_fileobj to return VersionId

[mdavis-xyz]

I want to upload a file and then get the VersionId.

With put_object the return value includes VersionId.
With upload_fileobj it doesn't include VersionId. In fact, upload_fileobj returns nothing at all.

I would like upload_* to return the same response as put_object.

Note that if I do a upload_fileobj then head_object, that's not atomic, so it's not guaranteed that the version id is the one for my upload.

Is the lack of return value because there's no return value here?

There's also no return value here

Hi @mdavis-xyz,

Thanks for your post. Yes, you are correct. The transfer manager doesn't return anything from the responses of the API calls used to complete an upload. One issue is that the response would be different depending on the upload method, if it was a single small object using PutObject or a larger one using a multi-part upload.

There is an existing feature request here for a different part of the response, I'm going to close this issue and mark it as a duplicate of that one.

Please 👍🏻 the initial post to indicate your need, and add any further use cases as well.

There is an issue open at s3transfer as well, for your reference, which gives a way to patch the classes used:
