This will be necessary when adding gitaly settings. This version
doesn't make any functional changes, but allows us to include this
breaking change in 9.0 and add the needed extra settings in the future
with backwards compatibility

This commit fixes a typo where the mode argument to FileUtils.mkdir()
would be passed in decimal rather than octal format, yielding bad
permissions.

Since version ruby-2.2.0, method `File::exists?` is deprecated.

Set permissions of backup dir to g+s

Closes #20188

Colorize is a gem licensed under the GPLv2, so we can’t use it in GitLab without relicensing GitLab under the terms of the GPL. Rainbow is licensed under the MIT license and does the exact same thing as Colorize, so Rainbow was added in place of Colorize.

The syntax is slightly different for Rainbow vs. Colorize, and was updated in accordance.

The gem is still a dependency of Spinach, so it’s included in the development/test environments, but won’t be packaged with the actual product, and therefore doesn’t require we relicense the product.

An attempt at relicensing Colorize was made, but didn’t succeed as the library owner never responded.

Closes #3311

This sidesteps problems with running 'chmod' on some CIFS mounts.

ProjectWiki.new() creates a new wiki git repository, so any tries
to bare clone a bundle fail. With this patch we remove the newly
created wiki.git before restoring from the backup bundle.

If a project is being restored, but there is no bundle file, the project was
empty when it was backed up.  In this case, just use git init --base to create a
new bare repository.

We need to skip empty repositories when creating a backup. Before this
change, we were asking gollum-lib if the wiki contains any _pages_. Now
we ask gitlab_git if the repository contains _files_. This should
resolve gollum_lib Grit timeouts in the backup script.

This change also shows the output of failed Git commands during the
backup.

The rewrite-hooks.sh script is a deprecated wrapper for gitlab-shell's
create-hooks script.

This fixes a bug where wiki repositories for projects with an empty main
repository would not get backed up.

The backup restore code for repositories was assuming that gitlab-shell
is installed in /home/git/gitlab-shell. This commit changes that to use
the configuration setting from gitlab.yml that specifies the path where
gitlab-shell is installed.

This reverts commit c46eaca9.
