Rename default branch from master to main

[sophie-h]

Posting this in release since I think all repos should be changed.

Maybe do this before the hackfest such that we can fix everything that is affected by this during the weekend?

As a first step this needs some documenting of the impact of this. Apart from switching the default branch in git, what is assuming a branch named "master"?

Probably the CI scripts, probably @GuillaumeGomez's release scripts. What else?

Also how do we make sure that people actually notice this change and we don't get bug reports in a few months from people running from a completely outdated master branch?

https://github.com/github/renaming/ sounds like github got us covered for many things.

Some background information https://about.gitlab.com/blog/2021/03/10/new-git-default-branch-name/. Looks like main will be the default in the majority of place pretty soon. Maybe it's less pain to do the change now.

The default branch for cargo is master. Another thing to be taken into account (for our end users).

The branch for cargo new depends on init.defaultBranch. Support for using the remotes default branch is only waiting for a release I guess https://github.com/rust-lang/cargo/blob/master/CHANGELOG.md#cargo-152-2021-05-06.

Not for new projects, for projects using gtk-rs as a dependency.

Yes I answered this in my comment too. Also, this change will probably be transparent for end users because GitHub redirects the branch https://about.gitlab.com/blog/2021/03/10/new-git-default-branch-name/ (also mentioned before.)

[GuillaumeGomez]

Oh indeed, well, that's one less concern then.

Progress with Rust 1.53

Cargo no longer assumes the default HEAD of git repositories is named master. This means you no longer need to specify branch = "main" for git dependencies from a repository where the default branch is called main.

Should we then maybe do it before the release now? :) @GuillaumeGomez @bilelmoussaoui ?

Sounds good to me
