I need to do some research about sources in a svn-deleted path in our company svn repository. Since I need to work a lot with annotate, I want to have the history in mercurial or git. I tried so far:

  • hgsubversion and git-svn: For both programs I can't find a way to specify that I need a older revision where the path existed, both try the svn HEAD and fail since the path is deleted there.
  • hgsvn: It finds the old path (with a peg revision), but fails to do the initial update, since it wants to get the log from the svn HEAD revision, where the wanted path doesn't exist anymore.

So is there a way to import a deleted svn path into git or hg?

    Would it be possible to do an `svnadmin dump` followed by an `svnadmin load` on a filtered input, ie. strip away the changeset that deleted the folder you want? – Lasse V. Karlsen Dec 08 '10 at 11:15

Assuming that the path was deleted on revision 117, the following should work with hgsubversion:

hg clone -r 116 http://svn.example.com/whereever

(I haven't tested this recently, but it should work. It's a bug if it doesn't…)

You should also note that despite what khmarbaise claimed, closing a branch in Mercurial does not delete it from history. Closing a branch will merely hide it from hg heads unless the -c/--closed argument is given.

As far as I know neither git nor hg is capable of handling deleted paths. If you delete a branch in git the branch is removed from history.

It's not clear from your question why you need git or hg. You can just use svn annotate. It is not a problem to analyze a deleted objects in SVN, you can use a peg revision like so:

svn annotate http://example.com/svn/somefile@321

This will work even when somefile has been deleted or renamed some time after revision 321.

edit: After thinking about it, I'm guessing you want hg/git because having a local copy of the repository might speed up annotation considerably. You can achieve the same with svn by creating a mirror repository on your local filesystem with svnsync, and accessing it with a file:/// URL.

  • You guessed right about the speed of each tool (running svn blame on the wrong file here means to wait for about 30s), but also does hg grep a good job when you search about when a specific line vanished from a file. – Rudi Dec 08 '10 at 14:05
  • @Rudi: perhaps [svnquery](http://svnquery.tigris.org/) can help? I haven't tested it yet but it should be faster than `hg grep` because it indexes the repository. – Wim Coenen Dec 08 '10 at 14:11
