h1. Search Engine Notes

• Running on Ruby 2.1.3.
• Using "Picky":http://pickyrb.com.
• Runs on Heroku (http://search.cocoapods.org).

h2. Developing

h3. Installation

• @bundle [email protected]
• @gem install [email protected]
• Create a @[email protected] table in a Postgres DB.

h3. Run locally with foreman

• @bundle exec foreman [email protected]
• @bundle exec foreman [email protected]

h3. Run tests

Disclaimer: Currently, the integration tests depend on a specific production DB dump. To download these, you currently need id/secret keys for an S3 instance, which only the CP team has access to. However, you can run specific specs which only require @[email protected] For example: @bundle exec bacon spec/lib/models/[email protected]

• All tests: @bundle exec [email protected]
• A single test: @LOAD_TEST_DB=absolutely bundle exec bacon spec/...../[email protected]

h3. Deploying to Heroku

• @git push heroku [email protected]

h3. ENV variables

You need to set the HOOK_PATH env variable for the Github post-receive-hook (see below for more detail).

@heroku config:set [email protected]

We also do not load test or development.

@heroku config:add BUNDLE_WITHOUT="development:test"@

We tune some GC variables.

@heroku config:add [email protected]

@heroku config:add [email protected]

@heroku config:add [email protected]

@heroku config:add [email protected]

h4. HOOK_PATH

We use one ENV variable (@[email protected]) to set the hook path we use in Trunk's post-receive-hook to update the search engine's index: @heroku config:add [email protected] This calls an URL on the app which causes it to update the search engine index for the updated pod from the Trunk database. (Note: It's not secure against brute force, man-in-the-middle etc., but a simple security to discourage DoS)

To change HOOK_PATH:

@heroku config:set [email protected]

Update the post-receive-hook in the Specs repo to the new garbled path.

h3. Notes
