From the administrator's chair, it's simple to break locks. The svnlook and svnadmin programs have the ability to display and remove locks directly from the repository. The more interesting option is allowing users to break each other's locks over the network. To do this, Sally simply needs to pass the --force to the unlock command:.
Now, Sally's initial attempt to unlock failed because she ran svn unlock directly on her working copy of the file, and no lock token was present. To remove the lock directly from the repository, she needs to pass a URL to svn unlock. Her first attempt to unlock the URL fails, because she can't authenticate as the lock owner nor does she have the lock token. But when she passes --force , the authentication and authorization requirements are ignored, and the remote lock is broken.
Simply breaking a lock may not be enough. In the running example, Sally may not only want to break Harry's long-forgotten lock, but re-lock the file for her own use. She can accomplish this by running svn unlock --force and then svn lock back-to-back, but there's a small chance that somebody else might lock the file between the two commands. The simpler thing to is steal the lock, which involves breaking and re-locking the file all in one atomic step.
To do this, Sally passes the --force option to svn lock :. In any case, whether the lock is broken or stolen, Harry may be in for a surprise. Harry's working copy still contains the original lock token, but that lock no longer exists. The lock token is said to be defunct. The lock represented by the lock token has either been broken no longer in the repository , or stolen replaced with a different lock.
Either way, Harry can see this by asking svn status to contact the repository:. If the repository lock was broken, then svn status --show-updates displays a B Broken symbol next to the file.
If a new lock exists in place of the old one, then a T sTolen symbol is shown. Finally, svn update notices any defunct lock tokens and removes them from the working copy. Different systems have different notions of how strict a lock should be. Some folks argue that locks must be strictly enforced at all costs, releasable only by the original creator or administrator.
They argue that if anyone can break a lock, then chaos runs rampant and the whole point of locking is defeated. The other side argues that locks are first and foremost a communication tool. If users are constantly breaking each others' locks, then it represents a cultural failure within the team and the problem falls outside the scope of software enforcement. In particular, the pre-lock and pre-unlock hooks allow administrators to decide when lock creation and lock releases are allowed to happen.
Depending on whether or not a lock already exists, these two hooks can decide whether or not to allow a certain user to break or steal a lock. The post-lock and post-unlock hooks are also available, and can be used to send email after locking actions. We've seen how svn lock and svn unlock can be used to create, release, break, and steal locks. This satisfies the goal of serializing commit access to a file. But what about the larger problem of preventing wasted time? For example, suppose Harry locks an image file and then begins editing it.
Meanwhile, miles away, Sally wants to do the same thing. She doesn't think to run svn status --show-updates , so she has no idea that Harry has already locked the file. She spends hours editing the file, and when she tries to commit her change, she discovers that either the file is locked or that she's out-of-date.
Regardless, her changes aren't mergeable with Harry's. One of these two people has to throw away their work, and a lot of time has been wasted.
