Re: New converstion tool: svn2git.py

Hi Neil,

You may want to look at this Ruby implementation for more ideas:

I forked it from a project originally by James Coglan, but should be
able to answer most questions about it.

Hi,

I'm working on a tool to do conversions from SVN to git using a SVN
dump.  It's in early development but perhaps some people would be
interested in it:

   http://python.ca/nas/python/svn2git.py

I would like to improve it so that it intelligently converts SVN
branches and tags into git branches (when possible).  The basic idea
is to map SVN paths into git branches, e.g. trunk -> master,
branches/foo -> branch-foo, tags/bar -> tags-bar.  Next, specific
SVN dump actions like:

   Node-path: branches/foo
   Node-kind: dir
   Node-action: add
   Node-copyfrom-rev: 3
   Node-copyfrom-path: trunk

need to be detected and the commit needs to performed with the
correct parent.  One complication is that SVN can create a branch or
tag from anywhere, for example, the action

   Node-path: tags/bar
   Node-kind: dir
   Node-action: add
   Node-copyfrom-rev: 3
   Node-copyfrom-path: trunk/subdir

would create tags/bar based on revision 3 of trunk/subdir.  There
doesn't seem to be a good way to convert that into git.  I was
thinking that the tags-bar branch in that case would have no parent.
Would git still efficently pack that or would you end up with extra
blobs?
