Merge conflicts
- Happen often
- Learning to fix conflicts is hard
- Practice makes perfect
- Force push after fixing conflicts. Be careful!
Merge conflicts
- Checkout a new branch and edit
conflicts.rb. Add 'Line4' and 'Line5'. - Commit and push
- Checkout master and edit
conflicts.rb. Add 'Line6' and 'Line7' below 'Line3'. - Commit and push to master
- Create a merge request and watch it fail
- Rebase our new branch with master
- Fix conflicts on the
conflicts.rbfile. - Stage the file and continue rebasing
- Force push the changes
- Finally continue with the Merge Request
Commands
git checkout -b conflicts_branch
# vi conflicts.rb
# Add 'Line4' and 'Line5'
git commit -am "add line4 and line5"
git push origin conflicts_branch
git checkout master
# vi conflicts.rb
# Add 'Line6' and 'Line7'
git commit -am "add line6 and line7"
git push origin master
Create a merge request on the GitLab web UI. You'll see a conflict warning.
git checkout conflicts_branch
git fetch
git rebase master
# Fix conflicts by editing the files.
git add conflicts.rb
# No need to commit this file
git rebase --continue
# Remember that we have rewritten our commit history so we
# need to force push so that our remote branch is restructured
git push origin conflicts_branch -f
Note
- When to use 'git merge' and when to use 'git rebase'
- Rebase when updating your branch with master
- Merge when bringing changes from feature to master
