git notes main page | gitolite main page | license

IMPORTANT NOTE: although this page has a "" URL, this is not about gitolite. That's just an artifact of "" being translated to "" and so ALL my git related stuff gets carried over. Gitolite documentation has another /gitolite in the URL, so you can tell. My apologies for this confusion.

converting CVS to git

Update 2009-10-08: It has been pointed out that cvsimport, which I recommend against using below, can do incremental imports. If this is important to you (it wasn’t, to me, and it never will be), then this document is probably no use to you. Sorry…

First: do NOT use the builtin git cvsimport unless your repository is very simple and linear. Problems I had using it on a moderately complex repo include missing tags, branches grafted to the wrong place (by comparing with a --simplify-by-decoration tree later), missing commits (which is what originally made me start investigating), and even missing files in the root of the repo!!

It’s been too long since I last used CVS to figure this out, and cvs2svn seemed to deal with a lot more nuances, so I used that instead.

1 step 1 – make a dump file

2 step 2 – import into git

These are the changes I made to the options file:
