Python agent v11.0.1

Notes

This release of the Python agent provides fixes for early activation in Django instrumentation, server side overrides for max_samples_stored being ignored, and guards against crashes from trace_cache.pop().

Install the agent using easy_install/pip/distribute via the Python Package Index or download it directly from the New Relic download site.

Bug fixes

• Prevents early activation in Django instrumentation

  • Remove calls to application_settings() in Django instrumentation to prevent issues with early activations in pre-fork applications.

• Fix server configuration to local configuration sync issues

  • This fixes a bug created when event_harvest_config.harvest_limits.* settings were deprecated in favor of *.max_samples_stored settings. Some server side configurations were not overriding the client side configurations, resulting in data being sent to the collector despite the user disabling this.

• Guard against crashes from trace_cache.pop()

  • In the ContextOf class, there was an unsafe access of the trace_cache via pop(key) without a default value. This caused crashes when the weakref in the dictionary was already garbage collected.
