Is there a way to make "git cvsimport" create branches in git for any branches it encounters in the CVS repository?

All my imports so far show just a linear line of development, and CVS branch information seems lost.

Best regards,

Wolfgang Denk

Heh. I was just preparing mail about the same problem. It seems that git-cvsimport-script really don't likes branches in CVS. I have attached simple script that demonstrates this. On my machine it gives: ============================= snake@home2:/tmp$ ./testscript cvs checkout: Updating project cvs add: scheduling file `a' for addition cvs add: use `cvs commit' to add this file permanently /tmp/20050717125452/cvsroot/project/a,v <-- a initial revision: 1.1 cvs tag: Tagging .

Umm, exactly what did you do to visualize that? "gitk origin" obvioously shows only one branch, because CVS doesn't have merge infe. Use "gitk $(cat .git/revs/heads/*)" to show everything.

s/v/f/

I see. Thanks for pointing out. Umm... is there a way to manually adjust this later? I can identify the specific PatchSet(s) which merge my CVS branches back into the trunk.

Best regards,

But it does not, at least in some cases. See my previous mail: http://marc.theaimsgroup.com/?l=git&m=112159075029007&w=2 It have simple script attached that reproduces the problem.

Ouch. It was all me. I have lost -A flag. Sorry for noise.

[offtopic]Re: "git cvsimport" with branches?

Sorry for noise again. I have found two bugs in cvsps that results in the wrong import to git. I tried to contact developer but it seems that his mail have no mailserver ATM. Since he has made some changes for git already - probably someone on this list have his new contact. Please tell me it or forward my mail to him. Thanks.

For the curious, here are the bugs:
1) some branches fork off too late - cvsps shifts brahches starts forward to 
the future
Example:
http://www.penza-gsm.ru/snake/testscript

2) some branches are not detected at all, not recorded as patchsets and 
consequently not imported into git.
Example (branch "old"):
http://www.penza-gsm.ru/snake/simplexml.py,v
