Git Usage Tips¶
Here are some tips for git workflow.
How to resolve conflict with master¶
First rebase to most recent master
# The first two steps can be skipped after you do it once. git remote add upstream [url to tvm repo] git fetch upstream git rebase upstream/master
The git may show some conflicts it cannot merge, say
Manually modify the file to resolve the conflict.
After you resolved the conflict, mark it as resolved by
git add conflicted.py
Then you can continue rebase by
git rebase --continue
Finally push to your fork, you may need to force push here.
git push --force
How to combine multiple commits into one¶
Sometimes we want to combine multiple commits, especially when later commits are only fixes to previous ones, to create a PR with set of meaningful commits. You can do it by following steps.
Before doing so, configure the default editor of git if you haven’t done so before.
git config core.editor the-editor-you-like
Assume we want to merge last 3 commits, type the following commands
git rebase -i HEAD~3
It will pop up an text editor. Set the first commit as
pick, and change later ones to
After you saved the file, it will pop up another text editor to ask you modify the combined commit message.
Push the changes to your fork, you need to force push.
git push --force
Reset to the most recent master¶
You can always use git reset to reset your version to the most recent master. Note that all your local changes will get lost. So only do it when you do not have local changes or when your pull request just get merged.
git reset --hard [hash tag of master] git push --force
What is the consequence of force push¶
The previous two tips requires force push, this is because we altered the path of the commits. It is fine to force push to your own fork, as long as the commits changed are only yours.
