Initializing svn repo from git

From: Chris Riddoch <hidden>
Date: 2016-06-15 22:43:00

Hi, folks.  This is probably targeted at Eric Wong, but any assistance
is welcome.  I asked on #git, and decideded that a larger audience
might be interested in this question, and whatever its answer turns
out to be.

I've been working on a project, and tracking its history in git.  Due
to lack of windows support, and windows-only developers joining my
project, my higher-ups decided that we needed to use SVN.  I expect
I'll probably use git-svn, myself, but I'm faced with a task:

I need to use the contents of my git repository, which is *very*
linear with only one branch, to fill in some history for a new, empty
svn repository.

My current steps, which isn't complete (identifiers cleaned out to
protect... well, me.)

$ git svn init  svn://server/project project
$ cd project
project$ git svn fetch
Fetching git-svn
r0 = df2d1a798e85c75b9abbfd22fe06ff651a8fa9dd
project$ git pull /git/project
warning: no common commits
remote: Generating pack...
remote: Done counting 850 objects.
remote: Deltifying 850 objects.

Um... now what?  Can someone walk me through this?

Oh, how I wish for a native Windows version of git.  That's the
*right* solution, I know.

In that case, feel free to Cc: me so I see it sooner :)

With completely linear history, you can probably use grafts and add
df2d1a798e85c75b9abbfd22fe06ff651a8fa9dd as a parent of your original,
initial commit.   Afterwards, running dcommit should just work.  (I've
never tried this, though).

That will probably force you to discard your git-only history
in SVN or have you duplicate history, neither is what you want.
If it's not too late; I recommend you start over with the
above instructions.
