To use mq you will need to enable the mq extension. This collapses all descendant commits, if you want control over which commits to collapse see MQ.

You can also use rebase to fold commits, just update to the parent commit then rebase the child commit to the same location but select the collapse the rebased changesets option. This will change the parent of the selected commit to the commit you are currently updated to (which doesn’t have to be the tip). Then right click on the commit you want to move and select Modify history > Rebase. Lets take the example that you have local commits and you’ve just done a pull and find someone else has already done a commit so that you now have two heads:įirst update to the commit you want to move your commit to: Rebase allows you to move one or more commits to the head of another branch. To use rebase you will need to enable the rebase extension. Services like Bitbucket add an option in settings that allow you to specify a commit that you want to strip. Note in order to remove commits on a remote repository the strip command will need to be run on that repository, you cannot do this through push. These files can be restored by going to View > Synchronize then clicking the Unbundle icon and selecting the file under the strip-backup folder. Note a backup of the commits you removed is kept under. To remove only the selected commit but keep the decendant commits see MQ. Just right click on the “Renamed help file, add service” commit then select Modify history > Strip: Let’s say you wanted to remove the “Renamed help file, add service” commit and descendant. Strip allows you to remove commits from your repository. To use strip you will need to enable the strip extension. Note a backup of the original commit is kept under. But it doesn’t allow you to undo removing or adding a file from the commit, for that see MQ. To do this you click the down arrow to the right of the commit button and select Ammend current revision:Īppend allows you to do things like modify the commit message, or add/remove/modify files. AppendĪppend is a quick way to allow you to modify the most recent commit. Secret is helpful when you are working on changes locally but don’t want to accidently push the commit when pushing other commits. By default you cannot modify a commit that is public until you change it back to draft by right clicking the commit and selecting Change Phase to > draft. The idea of the phases is so you know whether it’s safe to modify the commit or not. Secret - this commit will not be pushed, pulled or cloned.Draft - this commit has not yet been pushed to a public repository.Public - this commit has been pushed to a public repository (commits pushed to repos marked non-publishing remain in draft).Now in the commit history you will notice there is a column called Phase. If you want to undo a commit alternatively you can right click the commit and select Backout instead which will create a new commit that un-does the changes without modifying history. See changeset evolution on how this might not be such a problem in the future. So in general it is recommended not to modify history that has become public unless you know it’ll have no impact. It can also cause issues with automated test build systems that keeps the repository and just updates to the latest revision between builds. This might be easy to communicate if you’re working within a small team but becomes much harder to communicate if it’s a large team or an open source project online. This is something every developer has to do if they’ve pulled down the original commit. If you have local changes not yet pushed like in this example you would first have to move them over to the new commit using rebase before stripping the obsolete commits. To fix you would have to strip the obsolete commit.
So because the “Add workspace to app” commit was modified it now has a different hash (including all descendant commits since they’re modified too to update the parent hash reference since it’s changed), so it will appear as a different commit in the commit history alongside the original commit. The reason this happens is because commits are identified by their hash number (see identifying commits for more details). If another developer were to modify the “Add workspace to app” commit and you pulled down that change, this is what it would look like on your local repository: The risk with modifying history that you have pushed is if someone else has already pulled the commits down that you plan to modify. Firstly there is no risk to modifying history on commits that you have not pushed.
