Bubble up refresh exception when we cannot recover #434

rayluo · 2021-11-02T20:24:20Z

This will fix #431.

We won't have an easy way to test this. So, @jiasli please help the code review.

And, if the ConnectionError in Xing Zhuo's report is still observable, you can then pull in this feature branch and test it in rare real environment (by pip install git+https://github.com/AzureAD/microsoft-authentication-library-for-python.git@bubble-up-refresh-exception).

msal/application.py

        except:  # The exact HTTP exception is transportation-layer dependent
-            logger.exception("Refresh token failed")  # Potential AAD outage?
+            # Typically network error. Potential AAD outage?
+            if not access_token_from_cache:  # It means there is no fall back option


It is possible for access_token_from_cache to be not-None here? It seems L1198 will prevent a not-None access_token_from_cache to reach here.

Line 1198 would be skipped by line 1196. So, this check here is still beneficial.

Ah, I see. Even if AT_AGING refresh fails, access_token_from_cache can serve as a fallback. Thanks for the explanation.

Tested by manually changing expires_on in the token cache to make it expire, then disable the network adopter. I am able to get the expected error.

It fails at /54826b22-38d6-4fb2-bad9-b7b93a3e9c5a/oauth2/v2.0/token:
