从远程分支中拉出rebase与git fetch + rebase不同

Question

I have a problem. When I do this command

git pull --rebase origin dev

my local branch derives from my remote branch. When I do git log HEAD..origin/dev , Git displays some commits.

But (after a git reset --hard origin/dev ) when i do

git fetch origin dev
git rebase origin/dev

There si no derivation. No return for git log HEAD..origin/dev

Why and how can I do a git pull --rebase origin dev without derivation.

Answer 1

When you did your git reset --hard origin/dev , you changed your current branch (which I am assuming is dev ) to point to origin/dev . git fetch origin dev was probably a no-op, as you were already up to date due to your git pull earlier. So when you did git rebase origin/dev , nothing happened, as dev already pointed to origin/dev .

Had you done the fetch and rebase first instead of doing a pull, you would have seen the same list of commits as when you did the pull.
