Hi,

I am not sure whether this is a known limitation (possibly just me missing the trick). But I am using the fake-gcs-server as a mock through docker and where I have seeded with data. All of which works well.

I wanted to check whether the mock would be able to handle the e-tag directives when using the get_blob method of the Bucket object. It keeps returning the object even if I use the etag that was returned in a previous step for the same object.

I have control-checked by running against actual cloud storage and that seems to work as expected.

Example function call:

def get_object(self, path: str, etag: str = None) -> tuple(str, bytes) | None:
        blob = self.bucket.get_blob(
            path,
            if_etag_not_match=etag
        )

        if blob is None:
            return None

        return blob.etag, blob.download_as_bytes()

Thanks/Jonas

Hey, thanks for reporting and apologies for the slow response. I believe this is a missing feature in fake-gcs-server, yes.
