How can I undo my last accidentally commited not pushed change in Mercurial If possible a way to do so with TortoiseHg would be prefered Update In my concrete case I commited a changeset not pushed Then I pulled and updated from the server With these new updates I decided that my last commit is obsolete and I don t want to sync it So it seems that hg rollback is not exactly what I m searching for because it would rollback the pull instead of my commit

after you have pulled and updated your workspace do a thg and right click on the change set you want to get rid of and then click modify history - strip it will remove the change set and you will point to default tip

Its workaround If you not push to server you will clone into new folder else washout delete all files from your repository folder and clone new

hg rollback is what you want In TortoiseHg the hg rollback is accomplished in the commit dialog Open the commit dialog and select Undo

One way would be hg rollback deprecated as of Hg2 7 August 2013 Please use hg commit --amend instead of rollback to correct mistakes in the last commit Roll back the last transaction in a repository When committing or merging Mercurial adds the changeset entry last Mercurial keeps a transaction log of the name of each file touched and its length prior to the transaction On abort it truncates each file to its prior length This simplicity is one benefit of making revlogs append-only The transaction journal also allows an undo operation See TortoiseHg Recovery section This thread also details the difference between hg rollback and hg strip written by Martin Geisler who also contributes on SO hg rollback will remove the last transaction Transactions are a concept often found in databases In Mercurial we start a transaction when certain operations are run such as commit push pull When the operation finishes succesfully the transaction is marked as complete If an error occurs the transaction is rolled back and the repository is left in the same state as before You can manually trigger a rollback with hg rollback This will undo the last transactional command If a pull command brought 10 new changesets into the repository on different branches then hg rollback will remove them all Please note there is no backup when you rollback a transaction hg strip will remove a changeset and all its descendants The changesets are saved as a bundle which you can apply again if you need them back ForeverWintr suggests in the comments in 2016 5 years later You can un-commit files by first hg forgetting them e g hg forget filea hg commit --amend but that seems unintuitive hg strip --keep is probably a better solution for modern hg

In the current version of TortoiseHg Workbench 4 4 1 07 2018 you can use Repository - Rollback undo

Since you can t rollback you should merge that commit into the new head you got when you pulled If you don t want any of the work you did in it you can easily do that using this tip So if you ve pulled and updated to their head you can do this hg --config ui merge internal local merge keeps all the changes in the currently checked out revision and none of the changes in the not-checked-out revision the one you wrote that you no longer want This is a great way to do it because it keeps your history accurate and complete If 2 years from now someone finds a bug in what you pulled down you can look in your unused but saved implementation of the same thing and go oh I did it right

hg strip will completely remove a revision and any descendants from the repository To use strip you ll need to install MqExtension by adding the following lines to your hgrc or mercurial ini extensions mq In TortoiseHg the strip command is available in the workbench Right click on a revision and choose Modify history - Strip Since strip changes the the repository s history you should only use it on revisions which haven t been shared with anyone yet If you are using mercurial 2 1 you can uses phases to track this information If a commit is still in the draft phase it hasn t been shared with other repositories so you can safely strip it Thanks to Zasurus for pointing this out

[mercurial] Mercurial undo last commit

I believe the more modern and simpler way to do this now is hg uncommit. Note this leaves behind an empty commit which can be useful if you want to reuse the commit message later. If you don't, use hg uncommit --no-keep to not leave the empty commit.

hg uncommit [OPTION]... [FILE]...

uncommit part or all of a local changeset

This command undoes the effect of a local commit, returning the affected
files to their uncommitted state. This means that files modified or
deleted in the changeset will be left unchanged, and so will remain
modified in the working directory.

If no files are specified, the commit will be left empty, unless --no-keep

Sorry, I am not sure what the equivalent is TortoiseHg.
