This repository has the code for the Supermarket application and the omnibus definition used to build the deb/rpm packages. Other Supermarket related repositories are:

chef-cookbooks/supermarket-omnibus-cookbook: This cookbook is used to deploy Supermarket through the Supermarket omnibus package. For details on using this cookbook to install Supermarket omnibus, check out this webinar by the Supermarket Engineering team.

Development

Configuration

Configure the dotenv keys and secrets. See .env.example for required keys and secrets. docs/CONFIGURING.md page details the not-so-straightforward configuration information required to setup Supermarket working locally.

Local Environment

These instructions are tested and verified on macOS Catalina (10.15).

Dependency Services

As Docker Containers

Install docker
```
brew cask install docker
```

Ensure you have a PostgreSQL version installed on the local filesystem for development libraries to be available for building the pg gem. See the instructions for locally running PostgreSQL below, however omit the steps where the service is running.

Start the docker containers.
```
cd src/supermarket
docker-compose up
```

As Locally Running Processes

Install Postgres by following any of the below instructions:
- Install the Postgres App:
  
  This is probably the simplest way to get Postgres running on your mac. You can then start a Postgres server through the GUI of the app. If you go this route, then you'll have to add /Applications/Postgres.app/Contents/Versions/9.4/bin/ or the equivalent path to obtain the pg gem to build.
- Through Homebrew:
```
brew install postgresql
```
When installed through homebrew, Postgres often requires additional configuration, see this blog post for instructions. Ensure to start the Postgresql server by following the command given below.
```
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
```
Install Redis. You can install it with Homebrew. Follow the instructions in the install output to start the redis server.
```
brew install redis
```
Run the redis server using command:
```
redis-server --daemonize yes
```

Development Environment

Ensure you have Xcode installed.
Install a Ruby manager. If you don't already have one, you will need a Ruby manager to install the appropriate Ruby release, such as:
- RVM
- Rbenv
- chruby
- or any other Ruby version manager that may come along.
Use your ruby manager to install the necessary Ruby release. For instructions on this, please see the manager's documentation.
Ensure you have the Supermarket repo cloned to your machine. If not, clone it.
Navigate to that directory.
```
cd <supermarket-repo>
```
Again, navigate to the src folder.
```
cd src/supermarket
```

Install Bundler gem.

gem install bundler:2.1.4 --user-install

Install required gems:
```
bundle install
```
Note: You might encounter the following errors. The possible fixes are also provided here.
- Error installing gem: mimemagic
- Fix-> brew install shared-mime-info
- If you get error installing therubyracer and libv8 on macOS, follow the steps outlined in this link: https://billykong.github.io/ruby/2020/03/17/fixing-libv8-in-osx-catalina.html
Create the database, migrate to it, and then seed the database:
```
bundle exec rails db:setup
```
Add required Postgres extensions.
```
psql supermarket_development -c 'create extension plpgsql'
psql supermarket_development -c 'create extension pg_trgm'
```
Note: Ignore if the above 2 commands displays the following error: extension already exists.
Start the server:
```
bundle exec foreman start
```
Note: If you receive errors, ensure that redis and Postgres are running.

Setting up Auth

Supermarket uses oc-id running on a Chef Infra Server to authenticate users to Supermarket.

IF YOU ARE AN INTERNAL CHEF STAFFER - We will be performing some settings prior to set you up with oc-id. Consult the internal wiki on setting up your Supermarket dev environment (or ask a friendly team member!).

Note: Authentication currently requires a live Chef Infra Server running oc-id. We are working on a solution that would allow a developer to run the authentication locally. Stay tuned.

Create a new application and register it on oc-id (I called my application Application:Supermarket Development). Set the callback URL to http://localhost:3000/auth/chef_oauth2/callback or whatever localhost domain you use.

In your local copy of the Supermarket repo, copy the .env file to .env.development. Open up .env.development and replace these values:

CHEF_OAUTH2_APP_ID=YOUR_CHEF_OAUTH2_APP_ID
CHEF_OAUTH2_SECRET=YOUR_CHEF_OAUTH2_SECRET

with these values:

CHEF_OAUTH2_APP_ID=[Application ID of the oc-id application you just registered]
CHEF_OAUTH2_SECRET=[Secret of the oc-id application you just registered]

Restart your foreman server.

Now, when you click Sign In, you will be taken to your supermarket account with your Chef account!

Note: If you receive an omniauth csrf detected error, try clearing your browser's cache.

SPDX license linking for cookbooks

If a cookbook that has licenseId, which is also mentioned in SPDX license listed at https://github.com/spdx/license-list-data/blob/master/json/licenses.json, you need to update with respective license URL.

When a new cookbook is uploaded, license url information is fetched from the above link and is updated.

For an existing implementation of supermarket, there is a provision running with some ctl commands, for updating the information for cookbooks already there in system.

Following commands are available to update the license URLs for cookbooks:

Update licenses URLs for all the cookbooks in the system

spdx-all

Update for a single cookbook

spdx-latest <cookbook_name>

Update for a particular version of a cookbook

spdx-on-version <cookbook_name> <cookbook_version>

Connecting your GitHub Account

There are a couple of features that depend on GitHub integration (some quality metrics in Fieri) with your development environment. Follow these steps to create an application with your Github account:

Log into your Github account.
Click on your username in the upper right-hand corner. Your Profile page appears.
Click the Edit Profile button in the upper right corner of the Profile page.
Click Applications from the vertical menu on the left-hand side.
Click the Register new Application button from the section labeled Developer applications at the top of the screen.
Specify the name of your application (For example, Chef-Supermarket-Testing), then set the homepage URL as http://localhost:3000 (or whatever localhost domain that you use).
Set the Authorization callback URL to http://localhost:3000 (or your localhost domain of choice).
Click the Register application button.
Open the .env.development file in your local copy of the Supermarket repo.
Replace these values:

GITHUB_KEY=YOUR_GITHUB_KEY
GITHUB_SECRET=YOUR_GITHUB_SECRET

with:

GITHUB_KEY=[Your new application's client ID]
GITHUB_SECRET=[Your new application's client secret]

Next, create a Github Access token. You can also do this from the Applications section of your Profile page.

Tests

Requirements for tests: PhantomJS 1.8, Node.

Run the entire test suite (rspec, rubocop and mocha) with:

bundle exec rake spec:all

Acceptance Tests

Acceptance tests are run with Capybara. Run rake spec:features to run the specs in spec/features. The default rake spec also runs these.

When writing feature specs, the Rack::Test driver is used by default. If the Poltergeist driver is required to be used (for example, an acceptance test that uses AJAX), add the use_poltergeist: true metadata to the spec.

Some specs run using PhantomJS, which must be installed for the test suite to pass.

JavaScript Tests

The JavaScript specs are run with Karma and use the Mocha test framework and the Chai Assertion Library.

The specs live in spec/javascripts. Run rake spec:javascripts to run the specs, and rake spec:javascripts:watch to run them continuously and watch for changes.

Node.js is required to run the JavaScript tests.

Background Jobs

Read about Supermarket's background jobs in the wiki.

Feature Flags

Supermarket uses a .env file to configure itself. Inside this file are key/value pairs. These key/value pairs will be exported as environment variables when the app runs, and Supermarket looks for these keys as environment variables when it needs to read a value that's configurable.

One of these keys is called FEATURES and it controls a number of features that can be turned on and off. Here are the available features that can be toggled:
