coreunstable-1.18.0-beta.1

The following changes are from the previous release 1.17.0-beta.1.

• NuGet: OpenTelemetry.Exporter.Prometheus.AspNetCore v1.18.0-beta.1

  • Fix concurrent scrapes returning an empty response under contention. Now the exporter will return an HTTP 500 error instead.
    (#7571)

  • Waiting for concurrent scrapes to finish before collecting no longer blocks, which could stall concurrent scrapes being waited on.
    (#7571)

  • Fixed the interaction between PrometheusAspNetCoreOptions.TranslationStrategy and content negotiation. The configured strategy is now applied before content negotiation, instead of the negotiated escaping scheme replacing the strategy's, and the Content-Type header now reports the escaping scheme that was applied rather than the one that was negotiated.
    (#7610)

  • Fixed metric values and histogram bucket bounds being written with 17 significant digits instead of their shortest round-trippable representation.
    (#7589)

  • Fixed the canonical representation used for histogram le and summary quantile label values falling back to 17 significant digits incorrectly.
    (#7589)

  • Fixed a race where a slow scrape could return an HTTP 200 instead of 408.
    (#7615)

  • Updated OpenTelemetry core component version(s) to 1.18.0.
    (#7674)

  See CHANGELOG for details.

• NuGet: OpenTelemetry.Exporter.Prometheus.HttpListener v1.18.0-beta.1

  • Fix concurrent scrapes returning an empty response under contention. Now the exporter will return an HTTP 500 error instead.
    (#7571)

  • Waiting for concurrent scrapes to finish before collecting no longer blocks, which could stall concurrent scrapes being waited on.
    (#7571)

  • A scrape which is still collecting when the listener is disposed now returns an HTTP 503 response.
    (#7587)

  • Shutting down the listener no longer waits indefinitely for its request processing loop to stop, and no longer throws if the loop faulted.
    (#7587)

  • Fixed the interaction between PrometheusHttpListenerOptions.TranslationStrategy and content negotiation. The configured strategy is now applied before content negotiation, instead of the negotiated escaping scheme replacing the strategy's, and the Content-Type header now reports the escaping scheme that was applied rather than the one that was negotiated.
