CLAs look good, thanks!

Looks fine. Any reason why you don't just use the Blob.upload_* methods?

not particularly, either works

I think we've even debated making Bucket.upload_file a protected method to just encourage people to use the Blob directly.

Can you address the test failure:

TypeError: upload_from_filename() got an unexpected keyword argument 'content_type'

hm.. the test passes for me
I'll look into it tomorrow

Thanks. You are running the tests locally via tox, yes?

yes, I am also using the code in production

Notice it's a test fixture _Blob which encounters an unexpected keyword argument 'content_type': https://github.com/GoogleCloudPlatform/gcloud-python/blob/9c4867ab3a26b6f5e19f85c5d66e3c9083a8d83f/gcloud/storage/test_bucket.py#L525-L533
