feat(api-core): pass retry from result() to done() by IlyaFaer · Pull Request #9 · googleapis/python-api-core

If I understood everything correctly, the last thing that's left is to pass retry arg of a result() method to done(). Here it is.

This related to another PR: googleapis/python-bigquery#41, which implements retry passing from inheritors to PollingFuture

@busunkim96, friendly ping

+    def _done_or_raise(self, retry=DEFAULT_RETRY):
        """Check if the future is done and raise if it's not."""
-        if not self.done():
+        if not self.done(retry):


This should be passed as a keyword argument

Suggested change

if not self.done(retry):

if not self.done(retry=retry):

On further thought, since this is a new kwarg, we don't want to force all clients that subclass it to add it in order to use the next google-api-core (this is a breaking change).

We should really only populate retry at all when explicitly passed a value for one.

Maybe something like this?

Suggested change

if not self.done(retry):

done_kwargs = {}

if retry is not DEFAULT_RETRY:

done_kwargs["retry"] = retry

if not self.done(**done_kwargs):

@IlyaFaer We've been getting customer support tickets regarding retry settings, so I'd like to resurrect this PR.

We need to be careful with this, as there are likely subclasses that don't have a retry parameter. Forcing them to add a retry parameter is a breaking change.

To avoid breaking them, we need logic to only populate retry when clients support it (which I think is always true if we end up getting passed a non-default value for retry)

I tested this on the current version of google-cloud-bigquery and got many test failures.

@tswast, I've locally replaced dependencies in the way that it used a git repository version of api_core in unit tests, and, yeah, I see it too. Pushed the changes

I checked out these changes locally and verified they pass against the BigQuery test suite.
