1642705 - android_emulator_pgo.py can't connect to Marionette when run with Python 3

Status: RESOLVED FIXED

(Release Engineering :: Applications: MozharnessCore, defect)

Description

[Mitchell Hentges [:mhentges] 🦀]

I'm migrating mach python to use Python 3 instead of Python 2. In testing scripts that use mach python, I've found that the generate-profile-android-api-16-shippable/opt task starts to fail. See this example task.

I'm under the impression we've cut over to py3; does that mean we've resolved this issue?

Yep, I think you're right, closing :)
