Debian specific changes in gitlab ================================= 1. Redis connection: redis-server package in debian follows upstream default and listens on tcp port 6379. So gitlab package in debian is configured to use tcp sockets. gitlab developers recommend using unix sockets. You can change to using unix sockets by changing the following configuration files. /etc/redis/redis.conf and /etc/gitlab/resque.yml 2. wiki backend: debian package uses gollum-rugged_adapter whereas gitlab upstream still use gollum-grit_adapter. grit is no longer maintained and grit developers recommend switching to rugged. gollum-lib developers have announced their intention to switch to rugged_adapter by default and this is in progress. 3. default paths: debian package has changed some default values for paths which you can see at /etc/gitlab/gitlab-debian.conf 4. database: gitlab package configures postgresql database with peer authentication. 5. gem versions: some gem dependency requirements are relaxed to work with their packaged version in debian. You can find the list of gems required by gitlab and their corresponding package versions in debian at http://debian.fosscommunity.in/status/?appname=gitlab&sort=satisfied 6. vendored js files: some embedded javascript files in vendor/assets/javascripts are replaced by their packaged verion.
