How to update git submodule who's history was rewritten

Say I have a git submodule already setup, and the upstream commit history has rewritten (for example a rebase squash was preformed).

Say the commit my submodule head is set to no longer exits. So I want to set the head hash submodule’s repo’s head. How do I do that?

  • Proper git etiquette for users working in mostly-isolated branches?
  • Commit Related to changes is there but the changes are not reflected in the repo , why does this happen?

  • git push fails: RPC failed; result=22, HTTP code = 411

  • git pre-receive (push) hook detect if a merge was done in a specific file
  • Git push failed,could not resolve host

    You can simply go in the submodule, do a git fetch, and checkout the HEAD you need.

    cd mysubmodule
    git fetch
    git checkout origin/abranch

    Then you go back to the parent repo, add and commit that new submodule SHA1 entry.

    Note that you also can convert a submodule in order to follow the latest commits of a branch.
    In that case, a simple:

    git submodule update --remote

    would be enough.
