  • Guard session storage access
  • update type of collector_encryption
  • Fix propagator typo
  • Update typing on inclusion/exclusion patterns to match docs

0.24.0

  • Adds DataDog header support (#187)
  • Removes for..of loop to support IE11 (#189)

0.23.0

  • Add NodeJS instrumentation and shims (#184)
  • Adds B3 propagator (#177)

0.22.3

  • Fixes an issue where reporter cookies would be set with invalid key strings.

0.22.2

  • Completely defines the TracerOptions interface.
  • Updates thrift package to address a security vulnerability.

0.22.1

  • Fixes a bug where certain tracer tags were not set when using proto transport.
  • Adds TypeScript definitions for LightStep tracer specific options/methods
  • Fixes a crash when proto transport was used and invalid responses were received.
  • Adds an option to exclude cookies from tracing payloads.

0.22.0

  • The default transport has been changed to proto.
  • The tracer supports empty access tokens.
  • Several bugs have been fixed with the proto transport option around the report of LightStep-specific tags.
  • Addresses an issue with proto transport usage in the browser.
  • Fixes bug where error objects are not converted to log objects correctly.
  • Implements plugin for fetch.
  • Remove deprecated chrome.loadTimes() code.

0.21.1

  • Passing fractional timestamps to span start/finish are now properly handled.
  • Several bugs were fixed with the proto transport option around span duration and span ids.
  • We now support a custom logger function (thanks @Rowno), see README for more details.

0.21.0

  • Update thrift to 0.11.0. This breaks support for node.js versions <= 5.8.

0.20.14

  • Add new option to Tracer: disable_clock_skew_correction bool optional, defaults to 'false', which disables client-side clock kew correction.

0.20.13

  • Add new option to Tracer: transport string optional, defaults to 'thrift', which controls the transport method used to send reports to LightStep. Experimental Feature
  • Fixes a bug when logging verbosity was greater than 4 during report flushes.

0.20.9

  • Add new option to Tracer: collector_path string optional, which is an optional custom collector base path (if served behind a reverse proxy)

0.20.6

  • options function now only logs warnings when it sees a key name it doesn't know. Previously, it threw an error.

0.20.6

  • instrument_page_load option now defaults to false.
  • If xhr_instrumentation is enabled, Open Tracing headers are now properly sent with every xhr request, so long as that request is to a domain that matches the whitelist url rules and also does not match any of the blacklist url rules.

0.20.0

  • API CHANGE: use new lightstep.Tracer(opts) to return a lightstep Tracer instance
  • API CHANGE: lightstep-browser.min.js and lightstep-browser.js use a lightstep rather than LightStep prefix for LightStep symbols
  • API CHANGE: two new length limits for key-value logs: log_field_key_hard_limit and log_field_value_hard_limit, both specified as a number of bytes
  • Many implementation changes, especially support for key-value logging per OpenTracing-javascript 0.13.*

0.11.17

  • Update the internal, automatic tracer tags to follow the convention of using a lightstep.* prefix

0.11.16

  • Option verbosity=1 will now throttle the error logging to the first error per minute
  • Option delay_initial_report_millis will delay the initial report to the collector by at least some value between 0 and this value. This is useful when spawning a large number of new processes to help distribute the load at startup. Note: this is a non-standard option that is not supported by other LightStep libraries and is subject to change.
  • Back off on errors is more now more aggressive. The back off always uses the the reporting interval, not the clock calibration interval.

0.11.2

  • Fixes defects where the XHR instrumentation was still using the old parent option
  • Add documentation for the non-standard option disable_reporting_loop
  • Add documentation and implementation for the non-standard option disable_report_on_exit
  • Fixes the examples to use the newer OpenTracing APIs
  • Internal logging methods renamed (no external impact)

0.11.1

0.10.6

  • Enable gzip compression of Node.js reports from the client by default (this is controlled by a non-standard option gzip_json_requests)

0.10.5

  • Fix defect in error handling of failed requests

0.10.4

  • MINOR API CHANGE: verbosity level semantics updated
    • 2: echo all errors (but not warnings and info statements)
    • 3: echo all errors, warnings, and info statements
    • >3: same as 3 but will increasing level of detail

0.10.3

  • Add non-standard option report_timeout_millis

0.10.2

  • Add non-standard option default_span_tags

0.10.1

  • API CHANGE: Option verbose renamed to verbosity
    • 0: never echo anything to the host application's console
    • 1: echo only the first error to the host application's console
    • > 1: echo internal errors, warnings, and info statements to the host application's console. Higher values will yield more detailed logs
  • API CHANGE: Option debug is no longer valid and will generate an error if used
  • Internal errors, warnings, and info logs will no longer show up in the collected traces
  • Option log_to_console will no longer echo internal errors, warnings, and info logs
  • Adds CHANGELOG.md
