Is there a migration tool from CVS to Git?

Question

I intend to switch over from CVS to Git. In the case of SVN, there seems to be cvs2svn. Is there a similar tool to easily migrate from CVS to Git?

Answer 1

cvs2git

In addition to provided answers, here's a guide on how to convert cvs to git using cvs2git tool. Here, modulename is a name of CVS directory you want to import.

Prerequisites

cvs2svn package (which includes cvs2git command) should be already installed.

Update: steps 1 and 2 are not fully correct - before attempting, read the comment below by mhagger, the maintainer of cvs2git

1. checkout modulename

   cvs -d URL co -P modulename
   

2. create an empty CVSROOT needed by cvs2git

   mkdir modulename/CVSROOT
   

3. download an example of cvs2git.options at http://cvs2svn.tigris.org/svn/cvs2svn/trunk/cvs2git-example.options (user "guest" with no password)

4. edit cvs2git.options file. Replace r'test-data/main-cvsrepos' with 'modulename'. Edit authors transforms.

   # edit this
   run_options.set_project(  r'modulename',
   
   # and this
   author_transforms={
       'jrandom' : ('J. Random', 'jrandom@example.com'),
       'mhagger' : 'Michael Haggerty ',
   

5. run cvs2git to create git temp files

   cvs2git  --options=cvs2git.options --fallback-encoding utf-8
   

6. create git repository

   mkdir gitrepo && cd gitrepo && git init .
   

7. import from git temp files created by cvs2git

   cat ../cvs2git-tmp/git-{blob,dump}.dat | git fast-import
   

8. checkout working copy

   git reset --hard
