tl;dr: this will be a "Soft Close" to deal with glibc updates

As most of you know, upgrading glibc requires a reboot of each Linux host.
With so many hosts needing to be rebooted, there will be impacts on the
build and test machinery.

We fully expect the system to self-recover, but jobs in progress may burn.
So we are calling this a "Soft Close". While the trees remain open, devs
are expected to monitor their own jobs, and restart or cancel as needed.
Or, just enjoy a few more hours away from the keyboard.

Thanks for your understanding,

for the many Mozilla teams coordinating our response.

As Guardian of the Accept Header, that would be my question too.

Using Accept to detect APNG support will never be reliable because not
everyone who has shipped it sends the header. So you have to detect
support by sniffing anyway. So what does Accept give you, other than the
promise of perhaps being able to rely on it in 10 years time if nothing
else goes wrong?

pushes to Try not pushing all changesets will still pull in changes from
draft changesets previously pushed to Try.) See
https://hg.mozilla.org/integration/mozilla-inbound/rev/eee2e3b43fc1 for
more on this feature.

As part of this, the eslint task has been converted to a generic task and
now only runs if certain files change. This means e.g. C++ only pushes
shouldn't trigger eslint tasks.


Somewhat related, we should also only lint the files that were touched
by a given push. This ties in to the mozlint proposal I made awhile
back. I should really try and polish that up and get something landed.

Do you mean the Accept header? Not sure how Accept-Encoding makes sense here.

As for the MIME type to mention there, as I said in the bug I think we
should just ship image/apng (or video/apng though that seems a little
weird given the precedence set by GIF). Using the vnd tree makes no
sense for a format supported by multiple parties.
