Ruby agent release notesRSS

September 13, 2012
Ruby agent v3.4.2.1

Important

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Fixes

  • Fix issue when app_name is nil

    If the app_name setting ends up being nil an exception got generated and the application wouldn't run. This would notably occur when running a Heroku app locally without the NEW_RELIC_APP_NAME environment variable set. A nil app_name is now detected and an error logged specifying remediation.

Bug Fixes

  • Fix edge case in RUM auto instrumentation where X-UA-Compatible meta tag is present but </head> tag is missing.

    There is a somewhat obscure edge case where RUM auto instrumentation will crash a request. The issue seems to be triggered when the X-UA-Compatible meta tag is present and the </head> tag is missing.

  • Fixed reference to @service.request_timeout to @request_timeout in new_relic_service.rb. (Thanks to Matthew Savage)

    When a timeout occurred during connection to the collector an "undefined method request_timeout for nil:NilClass" would get raised.

  • preserve visibility on traced methods.

    Aliased methods now have the same visibility as the original traced method. A couple of the esoteric methods created in the process weren't getting the visibility set properly.

  • Agent service does not connect to directed shard collector after connecting to proxy

    After connecting to collector proxy name of real collector was updated, but ip address was not being updated causing connections to go to the proxy. Agent now looks up ip address for real collector.

  • corrupt marshal data from pipe children crashing agent

    If the agent received corrupted data from the Reqsue worker child agent it could crash the agent itself. fixed.

  • should reset RubyBench GC counter between polls

    On Ruby REE, the GC profiler does not reset the counter between polls. This is only a problem if GC could happen between transactions, as in, for example, out-of-band GC in Unicorn. fixed.

New Feature(s)

  • Major refactor of data transmission mechanism. This enabled child processes to send data to parent processes, which then send the data to the New Relic service. This should only affect Resque users, dramatically improving their experience.

Bug Fixes

  • Resolve issue with configuring the Error Collector when using server-side configuration.

Changes

  • Moved Resque instrumentation from rpm_contrib to main agent. Resque users should discontinue use of rpm_contrib or upgrade to 2.1.11.
