@hsvalava This looks great! Have you tested it to make sure it works as expected?

[hsvalava]

Hi Josh,
I tested console.log from the Firefox console, and it works (screenshot attached). The message is printed, and the file name and line number are dummy values for now.

[jdm]

Thanks for the proof :) I've left one comment on the Critic tool; be sure to click the 'sign in' link there so you get future updates by email.

[jdm]

Great! Could you squash your commits together now?

[hsvalava]

Hi Josh,
I squashed my commits together (git rebase -i --autosquash /master) but the push is getting rejected (non-fast forward updates). Am I supposed to force push the changes?

[jdm]

Yep, it's one of the few times that force pushing is encouraged :)

[hsvalava]

Done :)

Some test (./mach test-wpt --processes 4) failed.
Looks like it's run out of memory, or is it something else?
(pid:3754) "ERROR:net::image::base: stb_image failed: stbi_load_from_memory failed"
OSError: [Errno 12] Cannot allocate memory

[jdm]

Grumble. That's a new intermittent failure that we haven't figured out.

[hsvalava]

Thanks Josh! :)
