Rust 1.10 (to be) required to build Firefox with --enable-rust

[Nathan Froyd]

TL; DR: As the subject says, although the patch is not yet on
mozilla-central. You may want to pre-emptively update your Rust
before the build system requires you to.

We've not been particularly aggressive with requiring new Rust
versions, but with the release of 1.10, we wanted to start compiling
Firefox with '-C panic=abort'. Bug 1268727 tracks that work; patches
for said bug have landed on mozilla-inbound and seem likely to merge
to mozilla-central later today/this week. The configure machinery
will check the Rust version that you have and refuse to proceed
further if you don't have a new enough version.

Thanks,

Does MozillaBuild include the appropriate version of rust?

It does not...though judging from:

https://hg.mozilla.org/mozilla-build/file

it looks like we don't include Rust in MozillaBuild currently
regardless, as Rust is an optional build dependency at this point. (I
could be mistaken about Rust's inclusion, but clicking through files
revealed no obvious mentions of Rust.)

I filed bug 1294083[1] to track/discuss.

Thanks

I'll be marking that bug wontfix as soon as I get in front of a computer with my BMO credentials. We plan to have no more releases of MozillaBuild.

There is support for installing Rust via rustup in 'mach bootstrap'. That requires an msys2 environment, which we should be rolling out soon. In the interim, just use rustup manually.

Wasn't bootstrapping rust in MozillaBuild already fixed by bug
1177128[1]?

What will be the new way to get all build dependencies and tools for
Windows platform when MozillaBuild is discontinued?

Oh, right. I forgot we made a separate bootstrapper for MozillaBuild versus
msys2. So just run `mach bootstrap` in MozillaBuild and Rust things should
happen.

"Yes" ??? I'm not sure you understood the question here? Stefan, and myself
included, are curious what the new way to get all build deps after
MozillaBuild is discontinued.

Will the new procedure be to install Mercurial and Python, open the Windows
console, then clone mozilla-central, then run `mach bootstrap` ? Asking
users to install mercurial and python by themselves seems like a regression
to me.

Thanks,
Jared

I hope you don't think we'd increase the complexity of getting a Windows
development environment configured :)

We'll offer a standalone file that can be executed to install the
development environment.

Your snarky answer isn't very helpful.

Isn't MozillaBuild "a standalone file that can be executed to install
the development environment."

Phil (totally unclear of the difference)

MozillaBuild unzips into lots of files and programs. It's a whole
programming environment.

AIUI, gps is referring to something more like a single script. I.e.
basically just run "mach bootstrap" and everything is done for you, as
is the case on Mac and Linux.
