* download collection can be overridden like 'collection = aaa bbb ccc'.

    Use master instead.

    nexedi/slapos@000d0e5a (comment 4716)

So lamp-edge -> master

@rafael says:

    development stuff from marco, it was probably removed or not even
    included.

    In theory you can use master instead.

    nexedi/slapos@692729bc (comment 4713)

Shacache now uses CDN based URL for download.


  Update configuration to use CDN based domains for download date from CDN. 

See merge request !56

- GitLab Software + patches ported to latest stable GitLab 8.5.1
  (including fix for raw downloading to work in browser for private
repositories);
- Sync-with-upstream procedure streamlined (now only 1 branch for
  tracking upstream configuration files);
- Base software upgraded: Ruby, Redis, Nginx, Git;
- misc fixes.

    $ git diff 8.4.4+ce.0-0-g1680742..8.5.1+ce.0-1-ge732b39 --  \
        files/gitlab-cookbooks/gitlab/templates/default/sv-sidekiq-run.erb

shows nothing.

I manually reviewed

    $ git diff 8.4.2+ce.0-3-g68d5ee8..8.5.1+ce.0-1-ge732b39 \
        files/gitlab-config-template/gitlab.rb.template \
        files/gitlab-cookbooks/gitlab/attributes/default.rb

in omnibus-gitlab, and module proxy_set_header change, which we already
addressed in previous patch in Nginx config, there are no more changes
for us.

    - relative URL support: comment out - we do not need it - gitlab is
      always located at /.

    - Nginx-http: restore our version for proxy_set_header - upstream
      turned to allowing users to configure this, see e.g.

        https://gitlab.com/gitlab-org/omnibus-gitlab/commit/e13d5e42
        https://gitlab.com/gitlab-org/omnibus-gitlab/commit/a450585e

      but doing this way creates more complexity for gitlab SR, so I've
      restored our version which essentially does the same as default in
      omnibus-gitlab, and if we'll need to tune it - we can do directly in
      Nginx config.

      In other words slapos version does not allow users to tune nginx
      headers as instance parameter.
