v4.1.1

Bug Fixes

• deps: update dependency @opencensus/propagation-stackdriver to v0.0.16 (#1079) (e48dc54)
• docs: standardize README and add repo metadata (#1095) (c24faa3)
• force http and https clients to be patched (#1084) (3ac0b90)

v4.1.0

In this release, a log that is emitted by the Trace Agent when it's not the first required module has been downgraded from error-level to warn-level, and a new boolean config option disableUntracedModulesWarning disables this message entirely.

v4.0.0

This major release makes the following changes to the package:

BREAKING CHANGES

• Node 6 is no longer supported.
• Changes in config options: Users that use the following config options may see changes:
  • Config options contextHeaderBehavior and ignoreContextHeader now act independently of one another, and ignoreContextHeader is no longer deprecated. The former controls how a sampling decision is made based on incoming context header, and the latter controls whether trace context is propagated to the current request. (#1027)
  • When initialized with clsMechanism: 'none', calling Tracer#createChildSpan will potentially result in a warning, as these spans are considered to be uncorrelated. To ensure that warnings do not occur during automatic tracing, disable any plugins that patch modules that create outgoing RPCs. (Use of the custom span API Tracer#createChildSpan is not recommended in this configuration -- use RootSpan#createChildSpan instead.) (#1033)
• Changes in the custom span API: APIs that assume a particular format for trace context headers have been modified or removed; in other words, any place where the user would deal with a stringified trace context, they would now deal with a TraceContext object instead. (#1029) This affects three APIs:
  • Tracer#getResponseTraceContext (input/output has changed from string to TraceContext)
  • Tracer#createRootSpan (input RootSpanOptions now accepts a TraceContext instead of a string in the traceContext field)
  • Span#getTraceContext (output has changed from string to TraceContext)

If you do not use the custom span API or any of the config options above, there should be no breaking changes.

New Features

• Call stacks on traces now show pre-transpiled file/line numbers based on source maps. (#1015)
• Arbitrary tracing policy is now supported: the new config option tracePolicy allows users to write their own filters for traces, instead of using the built-in samplingRate, contextHeaderBehavior, ignoreMethods, and ignoreUrls. (#1027)
• Arbitrary HTTP trace header propagation is now supported: the new config option propagation takes in an OpenCensus Propagation object. It defaults to the Stackdriver Trace v1 header format exported by the package @opencensus/propagation-stackdriver; other OpenCensus propagation packages should work as drop-in replacements. (#1029)
• Every trace object now contains a trace and span ID, even if they were not sampled. (#1033)

Bug Fixes

• Requests to ignored URLs / with ignored methods no longer affect the frequency of sampled requests (they used to be factored in when sampling, causing un-filtered requests to potentially get sampled out erroneously). (#1018)

v3.6.0

This release makes the following changes:

• Tracing support for bluebird Promises has been added. Since Knex-specific tracing patches were being applied because it was using bluebird, the Knex patch has been removed. We don't expect Knex users to observe significant changes.
• Child spans can now extend longer than their parents.
