Git CVS tutorial

Say you want to checkout the mobile test suite into a git repository.

The W3C authoritative instructions use Concurrent Versions System. That’s good advice. Lets be crazy and use Git instead.

• git cvs in 5min

Lets checkout anonymously first:

CVSROOT=:pserver:anonymous@dev.w3.org:/sources/public cvs login

Password is ‘anonymous’.

x61:~/aplix/w3c% git-cvsimport -d :pserver:anonymous@dev.w3.org:/sources/public/ 2008/mobile-test
Initialized empty Git repository in /home/hendry/aplix/w3c/.git/
cvs rlog: Logging 2008/mobile-test
cvs rlog: Logging 2008/mobile-test/nored
x61:~/aplix/w3c%

With my W3C ssh ‘khendry’ login:

export CVS_RSH="ssh"
git-cvsimport -d khendry@dev.w3.org:/sources/public 2008/mobile-test

For a normal CVS checkout (for git-cvsexportcommit):

cvs -d khendry@dev.w3.org:/sources/public checkout 2008/mobile-test
export CVSROOT=khendry@dev.w3.org:/sources/public
cd 2008/mobile-test
export GIT_DIR=/srv/www/wct.localdomain/wct/.git
git-cvsexportcommit -v 1deec9ed09888
cvs commit -F .msg 'cookie.js'

You might experience a “too recent” message if you try update too soon.

x61:/srv/www/wct.localdomain/wct% git-cvsimport -v -d khendry@dev.w3.org:/sources/public 2008/mobile-test

A quicker push with a CVS checkout at ‘/tmp/w3c/2008/mobile-test’:

x61:/srv/www/wct.localdomain/wct% git-cvsexportcommit -v -c -w /tmp/w3c/2008/mobile-test ffceaad60e690600b2f56fd43755fe7e77da38ed

And finally check W3C mobile-test CVSweb if everything looks good.

I’m still not entirely sure how git merges back via git-cvsimport. Also unsure how this reflects in the remote gitweb view of my local wct git repository.

Just for my reference, just with CVS:

CVSROOT=khendry@dev.w3.org:/sources/public cvs co 2008/mobile-test
