Rename master branch to main in non-test repositories

[gsnedders]

Rendered.

This is more limited in scope than #80, because it excludes wpt and wpt-metadata, which is where most of the risk/complexity comes from. This doesn't mean to imply we should not do #80, but we should take the easier wins where we can.

sgtm

Although wpt.live needs approval from whoever owns the deployment of that, since it would probably be broken by this change.

Yay, I look forward to main in all repos I work with :)

@jcscottiii I tried to find where wpt.live is deployed but couldn't. Do you know where it is, and is "master" hardcoded anywhere in that setup?

LGTM from the wpt.live perspective. Deployments for the wpt.live infra are performed manually. As mentioned in the RFC, there are three references to master in the repo. -

• src/supervisord.conf: Tells the service to update it's local copy of the master branch for wpt. But since wpt's default branch is not updated, no change needed here
• infrastructure/web-platform-tests/compute.tf: While it is a only a comment, we should point the comment to GCP official docs
• .github/workflows/lint.yml: We will need to change this from master to main

Looking forward to this change. I can make the above changes once this RFC is merged.

I had a good laugh at the Risk section of the RFC.

I had a good laugh at the Risk section of the RFC.

Literally a copy/paste of @foolip's #80's risk section. 🙃

I can make the above changes once this RFC is merged.

FWIW, I was planning on doing this, changing src/supervisord.conf to fetch HEAD from upstream wpt (which eliminates one more thing we need to change when wpt finally renames its default branch); and changing .github/workflows/lint.yml to run on both master and main.

I have now done this for all the listed repos other than wpt.live.

(For those unaware, git remote set-head origin --auto will reset the origin/HEAD symbolic link based on upstream.)
