Sync with a remote repository
Before you can share the results of your work by pushing your changes to the upstream, you need to synchronize with the remote repository to make sure your local copy of the project is up to date. You can do this in one of the following ways: fetch changes, pull changes, or update your project.
When you fetch changes from the upstream, all new data from commits that were made since you last synced with the remote repository is downloaded into your local copy. This new data is not integrated into your local files, and changes are not applied to your code.
Fetched changes are stored as a remote branch, which gives you a chance to review them before you merge them with your files. Since fetch does not affect your local development environment, this is a safe way to get an update of all changes to a remote repository.
To fetch changes, from the main menu choose VCS | Git | Fetch.
Pulling changes from a remote repository is a convenient shortcut for fetching and subsequently merging changes. When you pull, you not only download new data, but also integrate it into your local working copy of the project.
From the main menu, choose VCS | Git | Pull. The Pull Changes dialog opens.
If your project has several Git repositories, select the path to the local repository that you want to update from the Git Root list.
Git Root list.
If you have several remotes configured for your repository, select the URL of the remote that you want to pull data from in the Remote list.
Select the branches that you want to fetch changes from and merge into the branch that is currently checked out.
From the Strategy list, select the in the Remote list.
Select the branches that you want to fetch changes from and merge into the branch that is currently checked out. The tracked remote branch is pre-selected.
From the Strategy list, choose the merge strategy that will be used to resolve conflicts that occur during the merge.
Select the following if necessary:
No commit: select this option if you do not want CLion to automatically commit merge results. In this case, you can inspect them and adjust if necessary.
No fast forward: select this option to generate a merge commit even if the merge was resolved as a fast-forward (that means only the branch pointer was updated).
Squash commit: select this option to create a single commit on top of the current branch instead of merging one or more branches. It produces the working tree and index state as if a real merge took place, but it does not actually make a commit or move the HEAD.
Add log information: select this option if you want CLion to populate the log message with one-line descriptions from the actual commits that are being merged in addition to branch names.
Click Pull to fetch and apply changes from the selected remote repository.
Update your project
If you have several project roots, or want to fetch changes from all branches each time you sync with the remote repository, you may find updating your project a more convenient option.
From the main menu, choose VCS | Update Project or press Ctrl+T. The Update Project dialog opens.
Select the update type (this strategy will be applied to all roots that are under Git version control):
Merge the incoming changes into the current branch: select this option to perform merge during the update. This is equivalent to running
git fetchand then
git merge, or
git pull --no-rebase.
Rebase the current branch on top of the incoming changes: select this option to perform rebase during the update. This is equivalent to running
git fetchand then
git rebase, or
git pull --rebase(all local commits will be put on top of the updated upstream head).
If you choose not to show the Update Project dialog in the future, and then want to modify the default update strategy later, in the Settings/Preferences dialog Ctrl+Alt+S select , select Update under Display options dialog when these commands are invoked, and modify the update strategy the next time you perform an update.
When the update operation is completed, the Update Info tab is added to the Version Control tool window Alt+9. It lists all commits that were made since the last sync with the remote, and lets you review the changes the same way as in the Log Tab.
