How to switch over from CVS to Git.
Document is here. →cvs2svn: cvs2git Documentation
Requires..
U can see ... from this link.
cvs2svn: cvs2git Documentation
- U can connect to CVS repo directly..( that is ... U execute on CVS sever...I think)
- Python version 2.4 or later
- git version 1.5.4.4 or later
- others...（If U want to use --use-rcs option, U need co programing. And If --use-cvs option, cvs command is required.）
Hmm....〆(._.)memo.
#python :) $python -V Python 2.4.3 #git :) $git --version git version 1.7.11.3 #CVS :) $cvs --v Concurrent Versions System (CVS) 1.11.22 (client/server) ry) $svn --version svn, バージョン 1.7.4 (r1295709)
Hmm,,,, It's probably ok(○ﾟεﾟ○)
get cvs2git
I did checkout from tigris's subversion repo, not download from download page.
$mkdir cvs2gitwork $cd cvs2gitwork/ $svn co --username=guest --password="" http://cvs2svn.tigris.org/svn/cvs2svn/trunk cvs2svn-trunk $ls cvs2svn-trunk $cd cvs2svn-trunk/ $ ls -l cvs2git -rwxr-xr-x 1 root root 2466 3月 26 21:56 cvs2git
SWITCH OVER CVS to GIT
At first, stop cron backup jobs.
I did on CVS server.
$ cd /tmp $ mkdir workcvs2git $ cd workcvs2git
execute cvs2git command
I found "imai" project, probably created by Mr. Imai in my company.
So I used project for trial.
$ cvs2git --encoding=utf_8 --encoding=shift_jis --blobfile=/tmp/workcvs2git/testblob.dat --dumpfile=/tmp/workcvs2git/testdump.dat --username=pnsk /usr/local/cvsrepo/imai
The statistics information is displayed as below and cvs2git job is completed.

Maybe I saw keyword "cvs2svn",,,,??? ( ﾟдﾟ)
It's my imagination..(つд⊂)
create git repo
U select "public" or "private", and NOT check "Initialize this repository with a README"
$ git clone git@xxx.xxx.xxx.xxx:pnsk/imai.git
Hmm,,, import dump files into git repo.

Tips
NOT check "Initialize this repository with a README"
If U checked, when U execute following command
$cat /tmp/workcvs2git/testblob.dat /tmp/workcvs2git/testdump.dat | /usr/local/git/bin/git fast-import
warning messages will be displayed as below.
warning: Not updating refs/heads/master
That is, Repo need empty.
encoding
When U execute cvs2git, if encoding options are insufficient,
error messages will be display..
ERROR: There were warnings converting author names and/or log messages to Unicode (see messages above). Please restart this pass with one or more '--encoding' parameters or with '--fallback-encoding'.
U have to add encoding options U need.
$cvs2git --encoding=utf_8 --encoding=shift_jis .....
Encoding lists is as follows.

push tags and branches
$/usr/local/git/bin/git push --all origin $/usr/local/git/bin/git push --tags origin
