OpenTracing

In this release we are happy to introduce the beta for the long-awaited OpenTracing compatible API layer for ddtrace!

Support for opentracing>=2.0.0 is provided in this release. Namely, the following are supported:

• start_span/start_active_span
• inject and extract functionality
• baggage, through set_baggage_item and get_baggage_item
• compatible tags from the OpenTracing specification
• scope manager support
• seamless integration with the Datadog tracer when using ddtrace-run

For setup information and usage see our docs for the Datadog OpenTracing tracer.

CI Improvements

Also included in this release are some optimizations to our CI which should get things running a bit quicker.

Thanks @labbati!

New integrations

• pymemcache integration (#511)

Celery integration

Due to some limitations with our Celery integration, we changed our instrumentation to a signals based approach. We also started using import hooks to instrument Celery, so that enabling the instrumentation doesn't trigger a celery import.

• Signals implementation: #530
• Moving to import hooks: #534
• Resolved issues: #357, #493, #495, #495, #510, #370

Breaking changes
Using the signal based approach increase the stability of our instrumentation, but it limits what is currently traced. This is a list of changes that are considered breaking changes in the behavior and not in the API, so no changes are needed in your code unless you want a different behavior:

• By default all tasks will be traced if they use the Celery signals API, so tasks invoked with methods like apply(), apply_async() and delay() will be traced but tasks invoked with run() will not be traced.
• patch_task() is deprecated; if it's used, all tasks will be instrumented

Bug fixes

• [core] check if bootstrap dir is in path before removal (#516 -- thanks @beezz!)
• [core] have hostname default to DATADOG_TRACE_AGENT_HOSTNAME environment variable if available (#509, #524 -- thanks @hfern!)
• [core] add WSGI-style http headers support to HTTP propagator (#456, #522)
• [core] Enable buffering on getresponse (#464, #527)
• [core] configure the root logger (#536)
• [aiopg] set the app_type during initialization (#492, #507)
• [boto] default to None if no region (#525, #526)
• [flask] avoid double instrumentation when TraceMiddleware is used (#538)
• [pymongo] fix multiple host kwargs (#535)
• [tornado] make settings object accessible during configuration (#499, #498 -- thanks @kave!)

Improvements

• [core/helpers] add a shortcut to retrieve Trace correlation identifiers (#488)
