1525118 - [meta] Run taskcluster task from mach try on Bitbar

Status: RESOLVED FIXED

(Core :: General, defect)

Description

[Edwin Takahashi (:egao | infrequent contributor)]

Bitbar has their win10/aarch64 device set up in their data centre.

Attempt a ./mach try push to try-server and have the task spin up on the win10/aarch64 hardware hosted at Bitbar.

win10/aarch64 hardware hosted at Bitbar running generic-worker 12.0.0 accepts build task and is able to successfully build and sign.

xpcshelltest is invoked and the tests are started, however according to the logs every test experiences a timeout. Eventually runxpcshelltests.py is no longer able to schedule new threads:

Issue may be due to chunk count not being set to 8 (default 1) for windows platform.

Previous run was building a win64/x86_64 image and using that on the win10/aarch64 hardware in an attempt to run xpcshell.

This obviously led to errors.

A newer run: efMBjsn0Q66A2tvOdHEHDw has been scheduled.

xpcshell has been confirmed to run successfully on the win10/aarch64 hardware, pushed through Taskcluster to the generic-worker. See test-windows10-aarch64/opt-xpcshell-1

Changes that were required to support this run as done by jmaher: https://hg.mozilla.org/try/rev/fb161d0cd20f46a2558cef0d75cb2185c903f3ed

The following changes were made by jmaher to add windows10-aarch64/opt and enable tests: https://hg.mozilla.org/try/rev/fb161d0cd20f46a2558cef0d75cb2185c903f3ed

Tests have been running on win10/aarch64 hardware for several hours, with good results.
