rustc 1.57 and cargo 0.58 to build firefox 97

[Olivier Tilloy]

This is a strict requirement for Firefox 97 since https://bugzilla.mozilla.org/show_bug.cgi?id=1744234

We will need rustc and cargo updates in jammy and all supported releases: bionic, focal, hirsute, impish. With a bit of luck hirsute can be ignored as it will be EOL on the 20th of January.

[Rico Tzschichholz (ricotz)]

The next bump of the rust requirement will be to 1.57.0

OK. Can you give some idea of timeframe for this? I find Firefox's release schedule to be a little baffling :)

(FWIW updating to rustc 1.56 seems to be smooth, I haven't tried 1.57 yet -- isn't packaged in Debian so far)

[Michael Hudson-Doyle (mwhudson)]

Also can someone clarify the extent to which rustc and cargo are interdependent these days? It seems it's no longer quite as vital to update them in lockstep. Like, will FF require cargo 0.58 or will 0.57 (which I think is the version from the rust 2021 edition?) do?

[Rico Tzschichholz (ricotz)]

The upstream build infrastructure is already using rustc 1.57.0 (https://bugzilla.mozilla.org/show_bug.cgi?id=1742749)

When the actual requirement bump will happen is hard to say. A vague time frame can be taken from https://bugzilla.mozilla.org/show_bug.cgi?id=1744102#c3

The rustc requirement was bumped to 1.57.0 a few days ago and firefox 97 will need it.

The firefox 97 beta phase begins January 10th.
