Rosetta Stone

Converting CVS-speak to git-speak

CMS CVS	CMS GIT
tagset	topic branch
publish a tagset	create a pull request
addpkg	git cms-addpkg
checkdeps	git cms-checkdeps
cmstc tagset <tagset-id> -a	git cms-merge-topic <topic-id>
cvs log	git log
cd $CMSSW_BASE ; cvs diff -r HEAD	git diff --staged
cvs diff	git diff --staged .
cvs diff -r some tag	git diff -r <some-tag>
cvs diff -r TAG1 -r TAG2 <path>	git diff TAG1..TAG2 -- <path>

Useful aliases to ease transition:

You can set up the given aliases by doing:

git config --global alias.cms-<alias-name> '<alias code>'

then you can reuse them via:

git cms-<alias-name>

it's recommended you prefix your aliases with "cms-" or "your-name-" so that people coming from the real world actually know about the fact it's not an official git command.

CVS command	git alias
cvs rdiff -r TAG1 -r TAG2 <package>	git config --global alias.cms-rdiff '!git-rdiff $@' ; git cms-rdiff TAG1..TAG2 -- <package>

Converting "Real World" git to "CMS" git

Rest of the world	CMS
upstream	official-cmssw
