Help: Trying to setup triangular workflow

 Hello

I am trying to set up a triangular workflow against a fork. The example I'm using is documented here: https://git-scm.com/docs/gitrevisions

Here's the example:

  $ git config push.default current
  $ git config remote.pushdefault myfork
  $ git switch -c mybranch origin/master
  $ git rev-parse --symbolic-full-name @{upstream}
  refs/remotes/origin/master
  $ git rev-parse --symbolic-full-name @{push}
  refs/remotes/myfork/mybranch

My setup looks like this:

  λ git -v
  git version 2.43.0
  λ git remote -vv
  myfork git@github.com:heymatthew/dactyl-configurator-fork (fetch)
  myfork git@github.com:heymatthew/dactyl-configurator-fork (push)
  origin https://github.com/rianadon/dactyl-configurator (fetch)
  origin https://github.com/rianadon/dactyl-configurator (push)

Here's what I get from running the documented example:

  λ git config push.default current
  λ git config remote.pushdefault myfork
  λ git switch -c mybranch origin/main
  λ git push
  * [new branch]          mybranch -> mybranch
  branch 'mybranch' set up to track 'myfork/mybranch'.
  λ git rev-parse --symbolic-full-name @{upstream}
  refs/remotes/myfork/mybranch
  λ git rev-parse --symbolic-full-name @{push}
  refs/remotes/myfork/mybranch

I was expecting @{upstream} to be origin/main, but it appears that @{u} and @{p} are the same.

Am I doing something wrong? Are there better examples someone can point me at to do this?

Thanks in advance :)

This push step is rewriting your upstream config. Do you have push.autoSetupRemote configured? In general you wouldn't want that for a triangular flow.

Though I think it also is only supposed to kick in if there is no tracking configured already. Why did the "git switch" invocation not set up tracking itself? When I run those commands it does. Do you have branch.autoSetupMerge turned off in your config?

Hi Peff,

 
Thanks for the pointer, yes have both push.autoSetupRemote and
branch.autoSetupMerge set. Turning these off has fixed my problem.

With neither option set the example yields:

  @{upstream}: refs/remotes/origin/main
  @{push}: refs/remotes/myfork/mybranch

With push.autosetupremote=true set:

  @{upstream}: refs/remotes/origin/main
  @{push}: refs/remotes/myfork/mybranch

With branch.autoSetupMerge=simple set:

  @{upstream}:
  @{push}: refs/remotes/myfork/mybranch

With branch.autoSetupMerge=simple and push.autosetupremote=true:

  @{upstream}: refs/remotes/myfork/mybranch
  @{push}: refs/remotes/myfork/mybranch

If you're interested in looking at my full gitconfig it's hosted here: https://github.com/heymatthew/dotfiles/blob/trunk/softlinks/.gitconfig

However looks like taking those out of global config has fixed my issue. Thanks for the help!
