gcloud._helpers._compute_engine_id should return a str (Python 3)

[pcostell]

From googleapis/google-cloud-datastore#92:

I stumbled upon this while deploying my app for the first time on GKE/GCE.

I had to explicitly specify project when creating a client: gcloud.datastore.Client(project="my-project"), otherwise I just got an gcloud.exceptions.ServiceUnavailable: 503 Backend Error.

First I thought the problem would be that autodetecting the project-id didn't work, but gcloud.datastore.Client(credentials=credentials, project=project) returns my project-id, be it as bytes instead of str.

I quickly verified that using bytes as a project-id does not work, i.e. gcloud.datastore.Client(project=b"my-project") resulted in that neat 503 Backend Error.

Thanks. This has come up before (I'll try to track down where). I wish there was an easy way to run system tests on GCE and GAE.

#1470 was when it came up. "Fixed" in #1505

@pcostell What version are you using? It seems like this should be all fixed in datastore-v1beta3 branch

[pcostell]

sorry I copied this from the Datastore issue tracker. @flunderpero, can you share what gcloud version you are using?

[dhermes]

DERP. Sorry I didn't even notice that

[flunderpero]

I'm using gcloud 0.11.0 installed from PyPi.

Thanks. Right now the datastore Client doesn't use the project mix-in. I "imagined" that the Client in the datastore-v1beta3 branch did "the right thing", but that hasn't been updated either.

Thanks for poking me into noticing this change was needed!
