If you checkout to your branch, reset can be used. |
Yes, I already mentioned that. But then I would lose my new commit, if HEAD is detached. 😉 |

Done.

Sometimes (especially when doing modifications in a submodule, inside a super-repo) I end up (accidentally) committing something at a "detached HEAD".
(It's also easy to cause a detached HEAD by using the
Checkout Commitcontext-command in the History graph, and then forget to checkout a branch before committing.)Having done such a "detached" commit, there is a risk of losing the commit (and being forced to rescue it from reflog) if then checking out a branch.
Most likely, at least in the submodule case, HEAD was already coinciding with a branch-tip before my commit. What I'd like to do in this situation is simply to "move" that branch-pointer forward to point at my new commit. (A more cumbersome alternative would be to: create a temporary branch/tag to point at the new commit, checkout the original branch and reset it to the new commit, then delete the temporary branch/tag.)
However, there is no command in SourceGit to (forcefully) "move" a specified local branch-pointer so it points at another commit. There is the '
Reset <branch> to Here' command, but that only works for a checked-out branch. On the Git command-line, on the other hand, it's easy to accomplish what I describe (using the--forceflag) :git branch -f <branch> HEADSuggestion: add a context-command for Local Branches, similar to the '
Fast-forward to <remote tracking branch>' command, allowing us to "move" (or "fast-forward") any local branch so it points at the current (detached) HEAD.The Git command for this would be
git branch -f <branch> HEAD, but the context action could be implemented in one of two variants (depending on how much "sanity-checking" we want to apply) :Fast-forward to HEADgit merge-base --is-ancestor <branch> HEAD; echo $?) to determine if<branch>can be fast-forwarded.Move to HEADThis command could be hidden or disabled (grayed-out) when HEAD is NOT detached. Alternatively, it could be always active, allowing us to re-point any local branch to the current commit (regardless of HEAD detached status).
NOTE: The 1st (safer) variant of this context-command could be incorporated into the 2nd (more general) variant, by implementing the ancestor-check as an option CheckBox '
Only allow fast-forward' (or similar) in a option/confirmation dialog for the command.The text was updated successfully, but these errors were encountered:
