0.26.0

on GitHub

WARNING:

This release has a bug calculating the content length for tracer payloads with more than 15 traces (per second). This miscalculation causes the agent to drop the payload. This is fixed in 0.26.2.

Improvements

• Flush traces to the agent when size exceeds 5MB. Use LMAX Disruptor for collecting/serializing traces. #710
  • Better performance for high throughput applications.
  • Allows more traces to be sent to the agent without exceeding the limit.
• Support for B3 formatted header injection/extraction #756
  • System Property:
    • dd.propagation.style.inject=Datadog,B3
    • dd.propagation.style.extract=Datadog,B3
  • Environment Variable:
    • DD_PROPAGATION_STYLE_INJECT=Datadog,B3
    • DD_PROPAGATION_STYLE_EXTRACT=Datadog,B3
  • Note: extract configuration is order specific.
  • Thanks @adriancole for the review.
• New config defining HTTP status code ranges to be marked as errors with the following defaults #772
  • This release had a typo in the config key, but is fixed in 0.26.1
  • System Property:
    • dd.http.client.error.statuses=400-499
    • dd.http.server.error.statuses=500-599
