Fix regex in redis version check
Created by: Bufallo
When i am executing "sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production" i run into an error on the redis version check:
Redis version >= 2.4.0? ... rake aborted!
ArgumentError: Malformed version number string 2.8.19 (git:0a21368c-dirty)
/home/git/gitlab/lib/tasks/gitlab/check.rake:340:in check_redis_version' /home/git/gitlab/lib/tasks/gitlab/check.rake:30:inblock (3 levels) in <top (required)>'
Tasks: TOP => gitlab:check => gitlab:app:check
(See full trace by running task with --trace)
On my Debian 7.9 i get the following result when executing "redis-cli --version": redis-cli 2.8.19 (git:0a21368c-dirty)
The current regex to extract the version number (.*) fails to extract a valid version number in my use case. So this pull request provides a updated regex to only extract a valid version number.
