@rafael says:

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

    In theory you can use master instead.

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.

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.

This does only pure merge. We will slaposify / adjust config and
corresponding md5sum in the following patches.

/cc @kazuhiko, @jerome

As it is said in 97dcf455 (gitlab: Establish proper 1 branch for
tracking upstream configs) we are switching to a model where we track
upstream configureation files on only one branch.

This merge does not change files on master - because we already have all
current upstream changes in - just establish a proper structure for future
updates.

/cc @kazuhiko, @jerome

Update GitLab software to

    - gitlab-ce 8.5.1 + NXD patches

      https://lab.nexedi.com/kirr/gitlab-ce/commits/8-5-nxd

    - gitlab-shell to 2.6.10 + 1 patch to remove unneeded hooks.old in *.git

      https://gitlab.com/gitlab-org/gitlab-shell/merge_requests/40

    - gitlab-workhorse 0.6.4 + NXD patches.

      https://lab.nexedi.com/kirr/gitlab-workhorse/commits/y/blobraw-4
      https://gitlab.com/gitlab-org/gitlab-workhorse/merge_requests/17

      ( download speedup patches got improved, and now also properly
        proxy _gitlab_session cookie to auth backend, so raw files for
        private repositories now open in browser ok )

This only updates software and begins SR update to 8.5 - for now gitlab
instance becomes non-working -- we'll pull in configuration files
updates and fixups in the following patches.

P.S. we also pin-up rubygems version, used to build gems, along the way.

GitLab uses git executable by full path as defined in gitlab.yml, but
not all places in code use it, e.g. here git is used just from $PATH

    https://gitlab.com/gitlab-org/gitlab_git/blob/2f0d3c1a/lib/gitlab_git/repository.rb#L259

So make sure to include our git into bundler-4gitlab PATH.

2.7.0 -> 2.7.2 is a bugfix release with several fixes:

1.9.4 -> 1.9.12 adds HTTP/2 support and removes SPDY support + other
bugfixes and improvements. We need HTTP/2 support for GitLab 8.5.

Changes with nginx 1.9.12                                        24 Feb 2016

    *) Feature: Huffman encoding of response headers in HTTP/2.
       Thanks to Vlad Krasnov.

    *) Feature: the "worker_cpu_affinity" directive now supports more than
       64 CPUs.

    *) Bugfix: compatibility with 3rd party C++ modules; the bug had
       appeared in 1.9.11.
       Thanks to Piotr Sikora.

    *) Bugfix: nginx could not be built statically with OpenSSL on Linux;
       the bug had appeared in 1.9.11.

    *) Bugfix: the "add_header ... always" directive with an empty value did
       not delete "Last-Modified" and "ETag" header lines from error
       responses.

    *) Workaround: "called a function you should not call" and "shutdown
       while in init" messages might appear in logs when using OpenSSL
       1.0.2f.

    *) Bugfix: invalid headers might be logged incorrectly.

    *) Bugfix: socket leak when using HTTP/2.

    *) Bugfix: in the ngx_http_v2_module.

Changes with nginx 1.9.11                                        09 Feb 2016

    *) Feature: TCP support in resolver.

    *) Feature: dynamic modules.

Changes with nginx 1.9.10                                        26 Jan 2016

    *) Security: invalid pointer dereference might occur during DNS server
       response processing if the "resolver" directive was used, allowing an
       attacker who is able to forge UDP packets from the DNS server to
       cause segmentation fault in a worker process (CVE-2016-0742).

    *) Security: use-after-free condition might occur during CNAME response
       processing if the "resolver" directive was used, allowing an attacker
       who is able to trigger name resolution to cause segmentation fault in
       a worker process, or might have potential other impact
       (CVE-2016-0746).

    *) Security: CNAME resolution was insufficiently limited if the
       "resolver" directive was used, allowing an attacker who is able to
       trigger arbitrary name resolution to cause excessive resource
       consumption in worker processes (CVE-2016-0747).

    *) Feature: the "auto" parameter of the "worker_cpu_affinity" directive.

    *) Bugfix: the "proxy_protocol" parameter of the "listen" directive did
       not work with IPv6 listen sockets.

    *) Bugfix: connections to upstream servers might be cached incorrectly
       when using the "keepalive" directive.

    *) Bugfix: proxying used the HTTP method of the original request after
       an "X-Accel-Redirect" redirection.

Changes with nginx 1.9.9                                         09 Dec 2015

    *) Feature: the "include" directive inside the "upstream" block.

    *) Feature: the ngx_http_slice_module.

    *) Bugfix: a segmentation fault might occur in a worker process when
       using LibreSSL; the bug had appeared in 1.9.6.

    *) Bugfix: nginx could not be built on OS X in some cases.

Changes with nginx 1.9.7                                         17 Nov 2015

    *) Feature: the "nohostname" parameter of logging to syslog.

    *) Feature: the "proxy_cache_convert_head" directive.

    *) Feature: the $realip_remote_addr variable in the
       ngx_http_realip_module.

    *) Bugfix: the "expires" directive might not work when using variables.

    *) Bugfix: a segmentation fault might occur in a worker process when
       using HTTP/2; the bug had appeared in 1.9.6.

    *) Bugfix: if nginx was built with the ngx_http_v2_module it was
       possible to use the HTTP/2 protocol even if the "http2" parameter of
       the "listen" directive was not specified.

    *) Bugfix: in the ngx_http_v2_module.

Changes with nginx 1.9.6                                         27 Oct 2015

    *) Bugfix: a segmentation fault might occur in a worker process when
       using HTTP/2.
       Thanks to Piotr Sikora and Denis Andzakovic.

    *) Bugfix: the $server_protocol variable was empty when using HTTP/2.

    *) Bugfix: backend SSL connections in the stream module might be timed
       out unexpectedly.

    *) Bugfix: a segmentation fault might occur in a worker process if
       different ssl_session_cache settings were used in different virtual
       servers.

    *) Feature: the ngx_http_v2_module (replaces ngx_http_spdy_module).
       Thanks to Dropbox and Automattic for sponsoring this work.

    *) Change: now the "output_buffers" directive uses two buffers by
       default.

    *) Change: now nginx limits subrequests recursion, not simultaneous
       subrequests.

    *) Change: now nginx checks the whole cache key when returning a
       response from cache.
       Thanks to Gena Makhomed and Sergey Brester.

    *) Bugfix: "header already sent" alerts might appear in logs when using
       cache; the bug had appeared in 1.7.5.

       appear in logs when using CephFS and the "timer_resolution" directive
       on Linux.

    *) Bugfix: in invalid configurations handling.
       Thanks to Markus Linnala.

    *) Bugfix: a segmentation fault occurred in a worker process if the
       "sub_filter" directive was used at http level; the bug had appeared
       in 1.9.4.

Redis 2.8.23 -> 2.8.24 is a small bugfix release:

    --[ Redis 2.8.24 ] Release date: 18 Dec 2015

    Upgrade urgency: MODERATE. We fixed a crash that happens very rarely, so
                     updating does not hurt, but most users are unlikely to
                     experience this condition because it requires some odd
                     timing.

    * [FIX] lua_struct.c/getnum security issue fixed. (Luca Bruno discovered it,
            patched by Sun He and Chris Lamb)
    * [FIX] Fix a race condition in processCommand() because of interactions
            with freeMemoryIfNeeded(). Details in issue #2948 and especially
            in the commit message d999f5a. (Race found analytically by
            Oran Agra, patch by Salvatore Sanfilippo)

    * [NEW] Log offending memory access address on SIGSEGV/SIGBUS (Salvatore
            Sanfilippo)
