Re: Canonical cinnabar repository

[Ethan Glasser-Camp]

Sorry if this is a bit off-topic. It seems from these threads that there is
a more-or-less canonical way to use git to hack on Firefox. Where can I
find out more about it?

Looking online, the only information I could find was at
https://github.com/glandium/git-cinnabar/wiki/Mozilla:-A-git-workflow-for-Gecko-development.
Is that the best source of information? I didn't see anything under
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide,
http://mozilla-version-control-tools.readthedocs.io/en/latest/, or
https://firefox-source-docs.mozilla.org/.

Thanks!

Ethan

Re: Have you run 'mach bootstrap' lately?

[Ethan Glasser-Camp]

Actually, I think my real question is "What is the intended way for
developers to keep their development environment up-to-date?" I don't think
that way should require a developer to answer questions, because the
answers presumably haven't changed since the last time they answered them.
If the intended way is `mach bootstrap`, then I think `mach bootstrap`
should have an option to skip the questions[*]. If `mach bootstrap` is only
intended to run once when setting up a new development environment, then
maybe there should be a `mach tune-up` command or something like that.

I'm happy to file bugs for whichever is the case, but I'm not sure which
one it is.

[*] When using `./mach bootstrap --settings ./mozconfig`, I get: `The
bootstrap command does not accept the arguments: --settings ./mozconfig`.
When using `./mach --settings ./mozconfig bootstrap`, I get the questions.

Is there a way to run it without having to reanswer the configuration
questions?
