How to import an svn repo into a mercurial one?

Question

I'm using the convert extension, so am not sure if it's the right tool, since:

hg convert svn://svn blah

gives:

svn://blah does not look like a Subversion repository

How do I do this, assuming that my repo doesn't have anonymous access?

Answer 1

You need to use a http URL to your subversion repository, or better yet bring the whole thing local with svnsync and use a file URL. Here are some more details:

Answer 2

Using the convert extension of Mercurial:

1. Enable convert extention; add convert= to the [extensions] section of .hgrc like this:

   [extensions]
   convert=

2. Linux needs additional python bindings: sudo apt-get install python-subversion
3. Execute hg convert command
   • See hg convert -h for help
   • Example: hg convert http://[svnserver]/[Project] --source-type svn [DestinationDir] (see note 2)
4. Push to newly created Mercurial repository: hg push https://[mercurialserver]/[Project]

note: you can even repeat the hg convert command to include new changes made in the svn repository after the previous convert.

note 2: When hg convert doesn't work using http:// or svn:// you could first checkout the Subversion repository (or update an existing one) and convert using the local checkout; example: hg convert [DirectoryOfLocalCheckout] --source-type svn [DestinationDir]
