Fetch after earlier fork
### Problem to solve When I fork a repository, I get up-to-date clone. I make a branch with a few commits and send a merge request. Everything is fine so far. A month later, I want to make another change. I go to the upstream repo, click "fork", and I get my long-ago forked repo which is now obsolete and many commits behind. Ouch. ### Proposal Please add "Fetch" (or "Pull") button to update earlier cloned repository from upstream. It should behave just like `git fetch`. The result should be the same as if I just forked the repo again (keeping my changes, of course). A simple brief preview may be useful. It may be reasonable to fetch only tags and master (default) branch by default. ### Use Case 1. Fork (clone) a repository via Gitlab web UI (the Fork button) 2. Create a feature branch in the forked repository, develop a feature 3. Someone updates upstream (original) repository 4. I want to update the forked repository. How can I do it? I'm too lazy to configure local repository with upstream remote repository. 5. [new feature] Hit "Fetch" button. Gitlab runs `git fetch` in the clone on the server. New upstream commits appear in my forked repository. 6. I run git fetch in local repository to get the new commits too. ### Future improvements - Fetch upstream changes automatically. - Fetch selected subset of branches and tags. We can start with two options: "Everything", and "Default branch and tags only". - Resolve conflicts on pull. We can start with a simple failure when Fast Forward pull is not possible. - Rebase.
