Ruby agent v3.17.2.327

December 13, 2016Download

v3.17.2

  • Compatibility with Ruby 2.4.0-preview3

    The Ruby agent has been updated to work on Ruby 2.4.0-preview3.

  • Early Access Sinatra 2.0 instrumentation

    Our Sinatra instrumentation has been updated to work with Sinatra 2.0.0.beta2.

  • Include controller instrumentation module in Rails 5 API

    The agent now includes the ControllerInstrumentation module into ActionController::API. This gives Rails API controllers access to helper methods like newrelic_ignore in support of the existing event-subscription-based action instrumentation. Thanks Andreas Thurn for the contribution!

  • Use Module#prepend for ActiveRecord 5 Instrumentation

    Rails 5 deprecated the use of alias_method_chain in favor of using Module#prepend. Mixing Module#prepend and alias_method_chain can lead to a SystemStackError when an alias_method_chain is applied after a module has been prepended. This should ensure better compatibility between our ActiveRecord Instrumentation and other third party gems that modify ActiveRecord using Module#prepend.

  • Use license key passed in to NewRelic::Agent.manual_start

    Previously, the license key passed in when manually starting the agent with NewRelic::Agent.manual_start was not referenced when setting up the connection to report data to New Relic. This is now fixed.

  • Account for DataMapper database connection errors

    Our DataMapper instrumentation traces instances of DataObjects::SQLError being raised and removes the password from the URI attribute. However, when DataObjects cannot connect to the database (ex: could not resolve host), it will raise a DataObjects::ConnectionError. This inherits from DataObjects::SQLError but has nil for its URI attribute, since no connection has been made yet. To avoid the password check here on nil, the agent catches and re-raises any instances of DataObjects::ConnectionError explicitly. Thanks Postmodern for this contribution!

  • Account for request methods that require arguments

    When tracing a transaction, the agent tries to get the request object from a controller if it wasn't explicitly passed in. However, this posed problems in non-controller transactions with their own request methods defined that required arguments, such as in Resque jobs. This is now fixed.
