2018-05-02, Version 2.8.0 (Beta), @kjin

This version adds a new configuration option, as well as minor changes to the custom span API.

Notable Changes

Configuration

  • A new configuration option config.clsMechanism is available, which can be used to disable automatic trace context propagation across asynchronous boundaries. This options should be considered advanced usage, and is intended to be used in conjunction with the custom span API with all automatic tracing plugins disabled.
  • A potential issue was fixed where the value of config.projectId isn't used if the environment variable GCLOUD_PROJECT is set to an empty string.

Custom Span API

  • A new function createChildSpan has been added to SpanData objects passed to the user with runInRootSpan (the type of which is now RootSpanData). Under normal circumstances, creating a root span using myRootSpan.createChildSpan should be identical to traceApi.createChildSpan when myRootSpan is automatically detected from CLS to be the current root span. This API was added to facilitate creating child spans when the current root span can no longer be auto-detected from CLS because the user disabled CLS through config.clsMechanism.
  • When a function passed to traceApi.runInRootSpan or traceApi.wrap throws, the trace context will correctly be reset to its original value before the function was run.
