Actually, I forgot to pull:

git remote add tdammers git@gitlab.haskell.org:tdammers/ghc.git
> git pull tdammers
git checkout tdammers some-branch

And to post changes to, say, GHC's main repo:

git push origin some-branch

Dear Simon,

In order for submodules to work, you still have to jump through the main repo. That is,

git clone --recursive https://gitlab.haskell.org/ghc/ghc tdammers
cd tdammers
git remote add tdammers git@gitlab.haskell.org:tdammers/ghc.git
git checkout tdammers some-branch

Dear ghc-devs,
More generally, I'm actually wondering, why GHC's .gitsubmodules use relative paths.  Why not make them absolute?

What is the right procedure for cloning from someone else’s repo.

For example, I wanted to see what was going wrong for Tobias in #16615, so after some detective work I tried

git clone --recursive git@gitlab.haskell.org:tdammers/ghc.git tdammers

but I got lots of errors:

Cloning into '/home/simonpj/code/tdammers/libffi-tarballs'...

setsockopt IPV6_TCLASS 8: Operation not permitted:

fatal: Could not read from remote repository.

 

Please make sure you have the correct access rights

and the repository exists.

fatal: clone of 'git@gitlab.haskell.org:tdammers/libffi-tarballs.git' into submodule path '/home/simonpj/code/tdammers/libffi-tarballs' failed

Failed to clone 'libffi-tarballs'. Retry scheduled

Cloning into '/home/simonpj/code/tdammers/libraries/Cabal'...

setsockopt IPV6_TCLASS 8: Operation not permitted:

Please make sure you have the correct access rights

and the repository exists.

fatal: clone of 'git@gitlab.haskell.org:tdammers/packages/Cabal.git' into submodule path

etc etc.

So:

  • What is a reliable way to get a MR onto my machine to test?
  • If I make a fix, what is the workflow to push that fix back to the author -- presumably I can’t push to their repo?

Thanks

Simon
