Fix relative URL
See https://github.com/gitlabhq/gitlabhq/issues/10053
- Same configuration way for relative URL like with Omnibus
- Loading the relative configuration from Rakefile as Rails do not load initializers for
asset:precompile
First point has another positive side effect: no collisions (due to git controlled application.rb) any more during the upgrades of source based installations and relative url configuration
-
tests on the source based installation -
tests on the centos&ubuntu omnibus packages
Fixes: gitlab-org/gitlab-ce#13730, gitlab-org/gitlab-ce#13727, omnibus-gitlab#1143 (closed) and https://github.com/gitlabhq/gitlabhq/issues/10053
