[TF-M] Re: Rename TF-M branches master -> main

Thanks, Gyorgy. Make sense to me. Good point in keeping the past releases operational.

Hi,

Just my two cents. I suggest a 4th option: Leave master as is, and make it read only. Branch off main from it and start contributing to the new branch. Reasoning:

* Eliminating master is likely to cause pain downstream. If you remove master, any old release which tries to check out a specific SHA from a specific branch (e.g. yocto machinery works like this), will be broken, and building them will become impossible without changes. Certificates bound to such a release may become invalid. * Refreshing main may create ambiguity and will allow users not migrating to the new branch. * If the "head" branch in gerrit is set to main, any client cloning without explicit branch specification will get main aniways. Hence risk of using the obsolete branch is somewhat mitigated.

Thanks!

Thanks, Andrew, Indeed, (1) is the simplest if we all can afford it.

Voting for option (1), to avoid deletion and confusion with syncing.

Hello,

Some time ago we planned to rename our master branch to main in all 6 repositories. There are multiple ways of doing that and I want to discuss with the community the best way suitable for all. I can see the following options:

1. rename master->main and use the main from one day. 2. Create the main for contribution with main->master sync. Make master R/O and delete it in 3 months. 3. Keep contributing to the master but syncing master->main. 4. Other way?

I suggest option 2 but looking for better alternatives if any.

Thanks, Anton
