You're using subversion and you accidentally checkin some code before it's ready. For example, I often: a) checkin some code, then b) edit a little, then c) hit up, enter to repeat the previous command which unfortunately was a checkin.
Is it possible to retract such an accidental checkin from the server with subversion?
See the SVNBook, specifically the 'Undoing Changes' section, and reverse merging.
Another common use for svn merge is to roll back a change that has already been committed. Suppose you're working away happily on a working copy of /calc/trunk, and you discover that the change made way back in revision 303, which changed integer.c, is completely wrong. It never should have been committed. You can use svn merge to “undo” the change in your working copy, and then commit the local modification to the repository. All you need to do is to specify a reverse difference:
$ svn merge -r 303:302 http://svn.example.com/repos/calc/trunk
To clarify, your initial change will still be in the repository. But you've now retracted it in a later revision. i.e. the repository has captured all your changes (which is really what you want! Unless you've checked in a plaintext password or similar!)
Using TortoiseSVN, select Show log and locate the revision that you want to revert to. From the context menu, select Revert to this revision. This performs a reverse merge into your working copy, so you will have to commit your working copy to finish the operation.
See also How do we keep track of our working copy's branch? :-)
If what you meant is, how do I cleanly remove the history of an accidental checkin: This is difficult.
svn does not allow you to undo anything since it saves revisions as changesets. However, there are some tools that let you do almost anything on a dump of a repository. You could:
Dump your repo.
Use svndumpfilter from the svn admin tools to get rid of the checkin.
Put it back into the repo.
But this can completely ruin your repo, so never ever try to do this, unless you absolutely know what you are doing and have everything backed up.
You cannot remove the revision - several answers here seem to be totally misunderstanding what you want. But you can change the checkin message to indicate that it it was unintended. Checkins don't cost very much so having the odd extra one is no big deal.
Yes, this is really what Subversion is for.
What you need to do is just replace your copy with previous revision in SVN repository.
There are several options:
But I strongly recommend you to do the following prior to replace your local copy:
I would doubt it. One of the main ideas of a source control is that a repository does not loose any history. You can't delete history. The best you can do is get an older version and overwrite the current one with that. But the history logs will still show your mistake.
(Offtopic: What kind of IDE are you using that does something like that?)
you cannot retract the revision, the most you can do is revert back to prior revision and do another checkin.
To comment on this as well: This is a series of commands that I did on a repository to revert it from revision 2 back to revision 1. You'd need to checkin at the end as well though.
