• Master:
• QA:

• Administrator privileges
• Bundler
• Git
• JDBC Oracle driver
• Java 8 SDK
• JRuby 9.1.14.0
• Node.js >=8.9.4
• Rubygems 2.5.1
• RVM - Ruby version managers

1. Install Java 8 JDK (8u172):

1. Install Homebrew:

   Install Homebrew

   /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

   Update Homebrew

   brew update

2. Fork this repository, then:

   with ssh (see Connecting to Github with SSH)

   git clone [email protected]:[your GitHub Account]/calcentral.git
   # e.g. git clone [email protected]:johnsmith/calcentral.git

   or via https - (see Caching Your Github Password in Git)

   git clone https://github.com/[your Github Account]/calcentral.git
   # e.g. git clone https://github.com/johnsmith/calcentral.git

1. Go inside the calcentral repository:

   cd calcentral
   # Answer "yes" if it asks you to trust a new .rvmrc file.

2. Install JRuby (requires ):

   Note: To install JRuby, you must first install rvm.

   rvm get head
   rvm install jruby-9.1.14.0
   cd ..
   cd calcentral
   # Answer "yes" again if it asks you to trust a new .rvmrc file.
   rvm list
   # Make sure that everything looks fine
   # If it mentions "broken", you'll need to reinstall

1. Make JRuby faster for local development by running this or put in your .bashrc:

   export JRUBY_OPTS="--dev"

2. Configure Default JRuby and Gemset

   cd ~
   rvm use jruby-9.1.14.0 --default # This may output 'Unknown ruby string (do not know how to handle): jruby-9.1.14.0.', which can be ignored.
   rvm gemset use global

3. Download the appropriate gems with Bundler:

   Important: Make sure you have the JRuby-upgraded CalCentral codebase in your calcentral directory before running bundle install.

   rvm rubygems 2.5.1 --force
   gem --version
   # Should output '2.5.1'
   
   gem uninstall bundler --force -x
   gem install bundler --version="1.15.4"
   bundle install

4. Set up a local settings directory:

   mkdir ~/.calcentral_config

   Default settings are loaded from your source code in config/settings.yml and config/settings/ENVIRONMENT_NAME.yml. For example, the configuration used when running tests with RAILS_ENV=test is determined by the combination of config/settings/test.yml and config/settings.yml. Because we don't store passwords and other sensitive data in source code, any RAILS_ENV other than test requires overriding some default settings. Do this by creating ENVIRONMENT.local.yml files in your ~/.calcentral_config directory. For example, your ~/.calcentral_config/development.local.yml file may include access tokens and URLs for a locally running Canvas server. You can also create Ruby configuration files like "settings.local.rb" and "development.local.rb" to amend the standard config/environments/*.rb files.

5. Install JDBC driver (for Oracle connection)

   • Download ojdbc7_g.jar
   • Note: You do not have to open the file.
   • Rename the file to ojdbc7.jar
   • Copy ojdbc7.jar to ~/.rvm/rubies/jruby-9.1.14.0/lib/

1. Make yourself a super-user:

   bundle exec rake superuser:create UID=[your numeric CalNet UID]
   # e.g. rake superuser:create UID=61889

2. Install Node Version Manager (NVM)

   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.1/install.sh | bash

   Configure your shell to use the Node version specified in .nvmrc.

   Open a new terminal window to ensure that NVM is present. If you go into the CalCentral folder it should recognize the .nvmrc file and install the version of Node specified.

   You can verify that it's using the right version using which:

   $ cat .nvmrc
   10.15.3
   $ which npm
   /Users/janesmith/.nvm/versions/node/v10.15.3/bin/npm

1. Install the front-end tools:

   npm install

2. Start the front-end development server, or kick off a Webpack build:

   # starts development server
   npm run dev
   
   # starts build process
   npm run build

3. Start the server:

   rails s

4. Access your rails server at localhost:3000, or the Webpack development server at localhost:3001. Do not use 127.0.0.1:3000, as you will not be able to grant access to bApps.

Note: Usually you won't have to do any of the following steps when you're developing on CalCentral.

Back-end (rspec) tests live in spec/*.

To run the tests from the command line:

rspec

To run the tests faster, use spork, which is a little server that keeps the Rails app initialized while you change code and run multiple tests against it. Command line:

spork
# (...wait a minute for startup...)
rspec --drb spec/lib/my_spec.rb

Front-end linting can be done by running the following commands:

npm run lint

This will check for any potential JavaScript issues and whether you formatted the code correctly.

Some features of CalCentral are only accessible to users with particular roles, such as student. These features may be invisible when logged in as yourself. In particular:

My Academics will only appear in the navigation if logged in as a student. However, the "Oski Bear" test student does not fake data loaded on dev and QA. To test My Academics, log in as user test-212385 or test-212381 (ask a developer for the passwords to these if you need them). Once logged in as a test student, append /academics to the URL to access My Academics.

1. Make sure you have a separate production database:

   psql postgres
   create database calcentral_production;
   grant all privileges on database calcentral_production to calcentral_development;

2. In calcentral_config/production.local.yml, you'll need the following entries:

   secret_token: "Some random 30-char string"
   postgres: [credentials for your separate production db (copy/modify from development.local.yml)]
   google_proxy: and canvas_proxy: [copy from development.local.yml]
     application:
       serve_static_assets: true

3. Populate the production db by invoking your production settings:

   RAILS_ENV="production" rake db:schema:load db:seed

4. Precompile the front-end assets

   npm run build

5. Start the server in production mode:

   rails s -e production

6. If you're not able to connect to Google or Canvas, export the data in the oauth2 from your development db and import them into the same table in your production db.

7. After testing, remember to remove the static assets, or run another build before the next task.

Make sure you are on the Berkeley network or connected through VPN for the Oracle connection.

Basic authentication will enable you to log in without using CAS. This is necessary when your application can't be CAS authenticated or when you're testing mobile browsers.

Note: only enable this in fake mode or in development.

1. Add the following setting to your environment.yml file (e.g. development.yml):

   developer_auth:
     enabled: true
     password: topsecret!

2. (Re)start the server for the changes to take effect.

3. Click on the footer (Berkeley logo) when you load the page.

4. You should be seeing the Basic Auth screen. As the login you should use a UID (e.g. 61889 for oski) and then the password from the settings file.

To help another user debug an issue, you can "become" them on CalCentral. To assume the identity of another user, you must:

• Currently be logged in as a designated superuser
• Be accessing a machine/server which the other user has previously logged into (e.g. from localhost, you can't act as a random student, since that student has probably never logged in at your terminal)

Access the URL:

https://[hostname]/act_as?uid=123456

where 123456 is the UID of the user to emulate.

Note: The Act As feature will only reveal data from data sources we control, e.g. Canvas. Google data will be completely suppressed, EXCEPT for test users. The following user uids have been configured as test users.

• 11002820 - "Tammi Chang"
• 61889 - "Oski Bear"
• All IDs listed on the Universal Calnet Test IDs page

To become yourself again, access:

https://[hostname]/stop_act_as

Logging behavior and destination can be controlled from the command line or shell scripts via env variables:

• LOGGER_STDOUT=false - Only log to the default files
• LOGGER_STDOUT=true - Log to standard output as well as the default files
• LOGGER_STDOUT=only - Only log to standard output
• LOGGER_LEVEL=DEBUG - Set logging level; acceptable values are 'FATAL', 'ERROR', 'WARN', 'INFO', and 'DEBUG'

1. On Mac OS X, to get RubyMine to pick up the necessary environment variables, open a new shell, set the environment variables, and:

   /Applications/RubyMine.app/Contents/MacOS/rubymine &

2. If you want to explore the Oracle database on Mac OS X, use SQL Developer.

See docs/styleguide.md.

Proxies running in fake mode use WebMock to substitute fixture data for connections to external services (Canvas, Google, etc). This fake data lives in fixtures/json and fixtures/xml.

Fixture files can represent time information by tokens that are substituted with appropriately shifted values when fixture data is loaded. See config/initializers/timeshift.rb for the dictionary of substitutions.

To view other rake task for the project: rake -T

• rake spec:xml - Runs rake spec, but pipes the output to xml using the rspec_junit_formatter gem, for JUnit compatible test result reports

Dev, QA, and Production CalCentral environments use memcached as a cache store in place of the default ActiveSupport cache store.

To set this up locally, perform the following steps:

1. Install and run memcached.

2. Add the following lines to development.local.yml:

cache:
  store: "memcached"

A few rake tasks to help monitor statistics and more:

• rake memcached:clear - Invalidate all memcached keys and reset memcached stats from all cluster nodes.

• rake memcached:get_stats - Fetch memcached stats from all cluster nodes. Per-slab stats may point out specific types of data which are being overcached or undercached, or indicate a need to reconfigure memcached.

• rake memcached:dump_slab slab=NUMBER - Shows which cached items are currently stored in the "slab" with the given ID. The list won't include the keys of expired or evicted items.

• WARNING: do not run rake memcached:clear on the production cluster unless you know what you're doing!

• All memcached tasks take the optional param of hosts. So, if say you weren't running these tasks on the cluster layers themselves, or only wanted to tinker with a certain subset of clusters: rake memcached:get_stats hosts="localhost:11212,localhost:11213,localhost:11214"

To selectively enable/disable a feature, add a property to the features section of settings.yml, e.g.:

features:
  wizbang: false
  neato: true

After server restart, these properties will appear in each users' status feed. You can now use data-ng-if in Angular to wrap the feature:

<div data-ng-if="user.profile.features.neato">
  Some neato feature...
</div>
