patch for git-daemon base-path trailing '/' problem

[Aneesh Bhasin <contact.aneesh@gmail.com>]

Hi All,

I was trying to setup git-daemon on our server with the following args :

git-daemon --base-path=/git_repo/ --export-all --syslog --inetd
--verbose /git_repo/external_repos/

There are two git repos in /git_repo/external_repos/ :-
linux-test/.git and linux-release/.git

When I try to clone the linux-test/.git repo using :
git clone 192.168.1.100/external_repos/linux-test

I get an error at the server side from git-daemon saying that
"/git_repo//external/repos/linux-test/.git not in whitelist".

The problem is because fo the trailing '/' in base-path in git-daemon
args. I think it might be fairly common that a person might add a '/'
at the end of base-path. The following patch takes care of this
trailing patch :
