1639024 - Convert 'mach mozharness' to run with Python 3

Status: RESOLVED FIXED

(Release Engineering :: Applications: MozharnessCore, task)

Description

[Kris Wright :KrisWright]

mach mozharness still runs with python 2 [1]. We want to convert all mach commands to python 3.

To do this, any dependencies of the command may need to be converted as well as the command itself.

Hi -- is there a status update on this work?

I think this is dependent on the test harnesses being py3 compatible. I haven't been directly involved in the porting, but I do know some patches have landed. #python may know more.

Very good question, I'm unsure. All (regular?) CI jobs doing ./mach python mozharness ... should by py3-compatible, but I'm not sure about the rest of it

Since ./mach mozharness is never run (IIRC), perhaps we can just rip that command out?

For context this command was only added to help developers replicate a mozharness invocation locally. It's not used in CI.

I was talking to James about this earlier.. We think it could definitely provide value with a little bit of work. That said I just tried to run it and discovered it's busted due to bug 1697919. I think removing it or fixing it up and making it useful are both viable options (I'm slightly inclined to the latter).

Either way, let's not block the py3 migration on this.. I'll just make it run with Python 3 and we can decide what to do with this later.
