GitLab

We decided not to support running ActionCable on a separate Puma process
so we no longer need these files

This is not used yet but merging this allows us to start writing
config management code in Omnibus etc. already.

This reverts merge request !62767

This is not used yet but merging this allows us to start writing
config management code in Omnibus etc. already.

This will be useful for supporting no-downtime upgrades. Admins
attempting to upgrade GitLab via our no-downtime upgrade procedure have
found that CSS and JavaScript often don't load while the upgrade is in
progress. This is because in a mixed deployment scenario with a load
balancer, this can happen:

1. User accesses node version N+1, which then makes a CSS/JS request on
version N.
2. User accesses node version N, which then makes a CSS/JS requests on
version N+1.

In both scenarios, the user gets a 404 since only one version of the
assets exist on a given server.

To fix this, we provide an alternate path where previous and future
assets can be stored.

This uses a standard-ish file format to save us re-inventing the wheel

This promise abstracts over a few different kinds of laziness we have,
without coupling super tightly to the GitlabSchema.

- This adds a configuration file for Lefthook which is more flexible
  and powerful than Overcommit.
- The only downside is that if gather the diff between `origin/master`
  and `HEAD` so if you didn't fetch `origin/master` for a long time,
  the checks might be done on more files than the one that you updated.
- Also, that means you need a origin remote.

- Configure rspec with Crystalball using custom CoverageLinesStrategy
for compatibility with SimpleCov on Ruby >= 2.5
- Running rspec with `CRYSTALBALL=true` generates crystalball data
in `crystalball/*.yml` containing files covered by each rspec example

In this commit we add a small functionality to generate the sitemap
for the `gitlab-org` group just in the .com environment.

The idea behind this is to analyze whether a broader sitemap
would improve the search crawling results.

Ignore the directory "sitespeed-result" created by "gdk measure".

Remove db/schema_migration files from .gitignore for old migrations that
exist on legacy installations but no longer have a corresponding
migration in the codebase. Due to changes in how the schema_migration
files are created, these files no longer need to be ignored.

This ensures only gitlab-kas can make requests to the internal API,
which is necessary as sensitive info is returned in response.

Update instances where we explicitly want to use the top-level

Rather than asking each contributor to sort out un-tracked files, we
ignore the db/schema_migrations for previously deleted migrations

asdf-vm uses a different file to other managers, this adds
.tool-versions to the ignore list, which is a file needed to manage the
Ruby version locally to this project.

This job runs in gitlab MR pipelines when
the pipeline is a pipeline for merged result.

It runs as if foss, without ee/ directory.
It detects ruby foss files changed and runs matching
rspec test files to detect any EE dependency
that might exist in FOSS.

Re-implement nodemon as a required module so that we can
remove the superfluous config file.

Allows for webpack to wholly or partly be cached on hard disk

`ee/lib/tasks/gitlab/license.rake` tries to load
`Settings.source.dirname + 'Gitlab.gitlab-license'` which expands to
`config/Gitlab.gitlab-license` for a default GDK installation.

This file should be ignored so developers can put their license files
and not worry about commiting the file.

Adds scripts to start Puma for ActionCable and example config
for GDK

Running Overcommit outside of the context of a Gemfile can lead to
conflicts when requiring gems. Using a dedicated Gemfile instead of the
default one avoids loading all the app's gems before running Overcommit.
