1651325 - frequent mozilla-beta test_ext_background_page.html dumps information with IGNORED REDUX ACTION, logs become too big to parse

Status: RESOLVED FIXED

(DevTools :: Console, defect)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Very frequently, mochitest plain tasks on mozilla-beta dump information with IGNORED REDUX ACTION during the execution of test_ext_background_page.html and the logs become too big to parse.

Examples:

Any idea why this affects beta so frequently but not trunk?

I don't really know why beta is more impacted.
This log has been causing issue since it was introduced, I think we can only log the action type (which is a string), and would resolve the issue

Attachment: Bug 1651325 - Only log action type in ignore middleware. r=bomsy.

The action object can hold complex data that would clutter the standard
output and make logs impoassible to parse (e.g. for treeherder).
