Move ARM64 Windows to stable tier-2 - #772
Conversation
Sorry, something went wrong.

I'm a bit hesitant to add this one to the stable set, as it tends to follow a cycle:
This is what we have, though, and AFAICT this is intrinsic to the platform rather than there being anything particular to this worker that causes it. It will just take some vigilance on my part to keep it going until such time as we (or the MS compiler team) find something to fix more permanently. test_os.TestScandir.test_attributes failure:
======================================================================
FAIL: test_attributes (test.test_os.test_os.TestScandir.test_attributes)

Note that restarting the system tends to fix this, but sometimes it takes an extra restart. I do not have any idea why that fixes it. |

Sounds reasonable to me. Tiers require reliable buildbots, so calling this behaviour unreliable while promoting ARM/Windows to T2 would be somewhat inconsistent :) |
