tent / tentd

Reference implementation of a Tent server in Ruby

Tentd - Protocol v0.3

If you're looking to self-host, see tentd-omnibus.

tentd is an alpha implementation of a Tent Protocol server. It currently contains broken code, many bugs, and security flaws. The code should only be used to experiment with how Tent works. Under no circumstances should the code in its current form be used for data that is supposed to be private.

       | S3_BUCKET                        | Bucket name

Google | GOOGLE_STORAGE_ACCESS_KEY_ID | Access key identifier | GOOGLE_STORAGE_SECRET_ACCESS_KEY | Access key | GOOGLE_BUCKET | Bucket name Rackspace | RACKSPACE_USERNAME | Username | RACKSPACE_API_KEY | Api key | RACKSPACE_AUTH_URL | Auth URL (European Rackspace) | RACKSPACE_CONTAINER | Container (bucket) name Filesystem | LOCAL_ATTACHMENTS_ROOT | Path to directory (e.g. ~/tent-attachments) Postgres | POSTGRES_ATTACHMENTS | Default. Set to true to override any of the other options.

Database Setup

createdb tentd
DATABASE_URL=postgres://localhost/tentd bundle exec rake db:migrate

Running Server

bundle exec unicorn

Running Sidekiq

bundle exec sidekiq -r ./sidekiq.rb

or

RUN_SIDEKIQ=true bundle exec unicorn

Heroku

heroku create --addons heroku-postgresql:dev,rediscloud:20
heroku pg:promote $(heroku pg | head -1 | cut -f2 -d" ")
heroku config:add TENT_ENTITY=$(heroku info -s | grep web_url | cut -f2 -d"=" | sed 's/http/https/' | sed 's/\/$//')
git push heroku master
heroku run rake db:migrate

Note: You will need to checkin Gemfile.lock after running bundle install to push to heroku

Testing

ENV Variables

name	required	description
TEST_DATABASE_URL	Required	URL of postgres database.
TEST_VALIDATOR_TEND_DATABASE_URL	Required	URL of postgres database.
REDIS_URL	Optional	Defaults to redis://localhost:6379/0. A redis server is required.

Running Tests

bundle exec rake

Sidekiq Config

# sidekiq client (see `config.ru`)
require 'tentd/worker'

# pass redis options directly
TentD::Worker.configure_client(:namespace => 'tentd.worker')

# access sidekiq config directly
TentD::Worker.configure_client do |sidekiq_config|
  # do stuff
end

# sidekiq server (see `sidekiq.rb`)
require 'tentd/worker'

# pass redis options directly
TentD::Worker.configure_server(:namespace => 'tentd.worker')

# access sidekiq config directly
TentD::Worker.configure_server do |sidekiq_config|
  # do stuff
end

# run sidekiq server from current proccess
require 'tentd/worker'

sidekiq_pid = TentD::Worker.run_server(:namespace => 'tentd.worker')

at_exit do
  Process.kill("INT", sidekiq_pid)
end

Note that blocks are called after calling config.redis = options (see lib/tentd/worker.rb)

• Refactor. The current code was hacked together quickly and is pretty ugly.
