The optional parameter will decide wheter to fetch using --force or not.
fetching with --force is a requirement for Gitlab Geo secondary node
replication.

Increase HTTP timeout and log request durations

On some GitLab deployments internal API calls regularly take more than
60 seconds (the default HTTP read timeout of Ruby's Net::HTTP). Until
we understand the cause of this slowness, by raising the client
timeout in gitlab-shell we can at least spare end users having to
retry their `git pull` or `git push`.

Pass $HOME to git as well

[ this patch has the same rationale and reasoning as
  https://gitlab.com/gitlab-org/gitlab-workhorse/commit/0d0bd209

  details follow ]

Git has 3 places for configs:

    - system
    - global (per user), and
    - local  (per repository)

System config location is hardcoded at git compile time (to usually
$prefix/etc/gitconfig). Local configuration is usually picked because we
pass full repo path to subcommand. But global configuration is currently not
picked at all, because HOME env variable is not passed to git.

Pass $HOME through and let git see it's "global" config.

Currently GitLab omnibus stores gitlab user name/email  + "autocrlf =
true" in global config, so missing it should not be a blocker for
receive/send-pack operations. But having it is more correct and can be
handy in the future if/when more git operations are done from-under
gitlab-shell.

Having $HOME properly set is also needed when one cannot change system
git config and have to put site-wide configuration into global git
config under $HOME.

That was the case I've hit and the reason for this patch.

Hoping this makes it more obvious when code touches the very
unsafe contents of this variable.

Passing strings to Kernel::exec leads to remote code execution.

Add support to connect gitlab-shell to Unicorn via UNIX socket  (v2)

Hello up there.

I'm doing SlapOS port of GitLab, and that means several different services could be running on the same machine, including several GitLabs.

So far all internal GitLab subservices could be glued together via UNIX sockets except gitlab-shell -> Unicorn link, which, when done via local TCP, requires firewall/network namespaces to protect services on one machine from each other.

On the other hand access to UNIX domain sockets is managed via regular UNIX permissions on filesystem, and thus is easier to manage. Besides UNIX domain sockets are well known to be faster compared to TCP over loopback - in particular to have ~ 2 times less latency and ~ 2 times more throughput.

From this point of view it makes sense to teach gitlab-shell to talk to Unicorn via UNIX socket and switch to that mode by default eventually.

I've just made a patch for this. Please apply.

Thanks beforehand,  
Kirill

Use load path, set ROOT_PATH via ENV
