Releases · DataDog/dd-trace-rb
0.9.0
New Integrations
- Faraday with Distributed Tracing support (#185, #212, docs)
- AWS SDK client (#179, docs)
- SuckerPunch (#194, docs)
- MongoDB Driver (#177, docs)
- Dalli (#196, docs)
- Resque (#204, docs)
Improvements
- [core] add a Processing Pipeline to filter or update spans before they're flushed (#214, docs)
- [transport] services are flushed in the same loop of traces, made exception if the Hash is empty; the timeout is set every second like before (#201)
- [core] add
Datadog.tracer.shutdown!
method to force sending traces before exiting the process; it's useful when your process exits before the flushing thread finishes to send data to the Datadog Agent (#195)
Bugfixes
- [rails] the template instrumentation works even if unexpected errors are raised; before this led to incomplete / unsent traces (#191)
- [rails] improve safety of
ActionController
instrumentation, making it robust when Rails signals are not executed in the expected order (#197) - [rails] use custom signals for cache instrumentation (#198)
- [rails] add the TraceMiddleware immediately instead of relying in another initializer (#208 -- thanks @Ferdy89 )

0.8.0
New features
- Experimental distributed tracing support. Distributed tracing allows you to connect your traces from different applications, and possibly different languages. This feature is disabled by default. Libraries supporting this are Rack and Net/HTTP (#141, #151 - docs, contributed by @whithajess, @ejholmes and @cabello)
Major changes
- Introduction of a context object, this is a deep refactoring which enables better future support of async behavior, and makes the Ruby library more similar to the Python implementation (#145)
Minor changes
- Jruby is back in our CI chain (#129)
- library is now tested against Ruby 2.4.1 (#159)
- Rails 3.0 support. As this is a deprecated Rails version, our support for this is "best effort". (#154, #157, contributed by @dorner)
- Adds a PID a as tag to root spans, so that you can know which process the trace belongs to (#147).
Breaking changes
Span
constructor does not set thestart_time
any more. The start time is now set when callingstart_span
from theTracer
. This should not have any impact if you either useTracer.trace
or use out-of-the box integrations. The only side-effect is if you were working on a custom integration.- the
finish_at
method of theSpan
object, which was marked as deprecated in0.7.2
, has been completely removed. It can be safely replaced withfinish
, which takes an optional argument.
For example:
span.finish_at(timestamp)
becomes:
span.finish(timestamp)
And if you don't need to give a specific timestamp, this defaults to now
:
span.finish()
Bugfixes
- documentation updates (#136, #144, #146, #152, with the help of @emaiax, @cabello and @tobypinder)
- don't treat http
4xx
return codes as errors (#103. #162, with the help of @sj26) - catch
Exception
and not onlyStandardError
when it makes sense to do so (#120, #158, #160, suggested by @Ferdy89). - limit span and trace IDs to 63 bits (#161)
Special thanks to all contributors, who made this release possible.

0.7.2
Bugfixes
- [tracer] ensuring submitted spans belong to the same trace, this fixes a possible data loss with message
dropping trace reason: trace id mismatch
when using threads (#133) - [doc] added missing comma for Rack example, thanks @elyara for fixing this (#130)

0.7.1
New features
- it's now possible to configure Sidekiq service on a worker level, contributed by @krasnoukhov (#124, #125)
Minor changes
- a header
X-Datadog-Trace-Count
is now sent when posting payloads to agent, it contains the number of traces in the payload (#123)

0.7.0
New features
- add a Rack middleware that can be used with any web framework compliant with the Rack interface (#111, #116 - docs)
- add Grape auto instrumentation to trace all endpoints execution and
before-after
filters (#117 - docs) - Rails integration can activate the Grape instrumentation using the
auto_instrument_grape
flag in the Rails initializer file (docs)
Major changes
- Rails uses out of the box the Rack middleware so that the full request processing is traced. Before, only the Rails controller was instrumented, making difficult to see anything that happens outside of the Rails framework. While this changes how some traces are displayed, it doesn't introduce any breaking change with previous versions (#112, #118, thanks @Ferdy89 for the contribution!). However, you can expect changes around the displayed names/URLs.
Bugfixes
- in some cases, Rails app would drop spans because they would have no service and not be properly instrumented. This, causing wrong stats and partial traces. It's now fixed with the new rack support (see above, #112)
Span
instances can be finished only once (#109)- stacktraces are constructed with proper newline characters (#108 and #115, contributed by @Ferdy89 )
ddtrace
logs are easier to isolate from your apps log (#107)

0.6.2
New features
- Active Record support for Sinatra apps, many thanks to @cabello for this contribution (#88)
- When no service is given for the root span, a default one is picked up,
to avoid dropping traces in the agent (#105)
Bugfixes
- Rails env is not used as a default env any more (#106)
Breaking changes
- If you use Rails and rely on the new
env
feature introduced by #92 in https://github.com/DataDog/dd-trace-rb/releases/v0.6.1 then you now need to explicitly set the value.
A typical Rails configuration would be:
Rails.configuration.datadog_trace = {
auto_instrument: true,
auto_instrument_redis: true,
env: Rails.env,
}

GET /index
now reports asGET
instead of/index
(#98)
