converting svn repo to git using reposurgeon

Question

I am trying to convert an svn repo to git using reposurgeon.

Here is what I did ( have a repo.map file that has the svn name -> git name mapping):

svnadmin dump /home/subversion > repo.svn
reposurgeon "verbose 1" "repo.svn" "authors read" "write repo.fi"

reposurgeon runs for many hours (lots of swapping as it is a 12GB dump file), and everything looks good. Here is the output I get:

    reposurgeon: verbose 1
    reposurgeon: from repo.svn...copynodes+filemaps+copysets+commits+branches+parents+root+branchlinks+svn-mergeinfo+tagifying+tagify-empty+polishing+canonicalizing+resets+debubbling+renumbering+14163 revisions (1/s)...(9810.18 sec) done.
reposurgeon: r13: deleting parentless zero-op commit.
.
.
.
reposurgeon: r13726: deleting parentless zero-op commit.
    2012-12-24T01:16:23Z * repo.svn

At this point reposurgeon just sits. I'm not sure where to look for a solution at this point, as it never actually gives me an error message. Any suggestions are most welcome.

You should try asking somewhere ESR hangs out, like IRC. That looks like a lot of commits, he recently introduced some performance optimizations that may interest you. — mikewaters

@DanielJacobs: have you tried running the job interactively? I have noticed subtle discrepancies between running stuff on the command line and from a script. I also use the interactive prompt to develop my lift script. — 0xC0000022L

It's successfully imported the repository, but then it goes to process the authors read command, but you didn't specify a file. At this point it's actually waiting for the file to appear on stdin. Use authors read <author-map where author-map is the name of the file containing the map.

You'll also want to change the write command to write >repo.fi, for similar reasons.

How do I get such an author-map?

the author-map is just a text file that you create containing lines that look like "ferd = Ferd J. Foonly <[email protected]> -0500".
