v1.4.3

What's Changed

• Do not prefix "error" attributes with the configured prefix since these have special meaning in open telemetry

Full Changelog: v1.4.2...v1.4.3

v1.4.2

What's Changed

• Bump opentelemetry_exporter from 1.4.1 to 1.5.0 by @dependabot in #111
• Ensure that keys are strings before we call Span.set_attributes (#114)
• Adds with_span decorator (delegates to trace, so you can use either)
• Ensure attributes set with the helper get prefixed

Full Changelog: v1.4.1...v1.4.2

v.1.4.1

v1.4.1

Features

• Adds span set attribute helper that treats attributes the same way :include does (currently inspects anything it doesn't know how to handle) (thanks @ulissesalmeida)
• Updates :include attribute validator to allow nested string keys (thanks @leggebroten)

Bug fixes

• Fixes an issue where indexing into a nested struct via :include would crash due to a *Struct* does not implement the Access behaviour error
• Protect against context corruption (thanks @leggebroten)

Full Changelog: v1.4.0...v1.4.1

v1.4.0

What's Changed

• You're now able to :include nested result elements e.g. include: [[:result, :name]]
• You're now able to index into string keyed maps e.g. include: [[:user, "id"]]
• Complex object attributes (lists, maps, tuples, etc.) are now inspected rather than omitted from the trace
• 🚨The default joiner for nested attributes is now . rather than _ e.g. user.id=1 rather than user_id=1🚨
  • You can change this behavior via configuration e.g. config :open_telemetry_decorator, attr_joiner: "_"

New Contributors

• @leggebroten made their first contribution in #107

Full Changelog: v1.3.0...v1.4.0

v1.3.0

Introduces a breaking (kind of) change. The API hasn't changed at all, but it will no longer overwrite function input parameters in the span attributes if they are rebound in the body of the function.

e.g. this param_override(3, 2) will add x=3 to the span, where previously it would have been x=4

@decorate trace("param_override", include: [:x, :y])
def param_override(x, y) do
  x = x + 1

  {:ok, x + y}
end

v1.2.7

• The trace decorator will no longer eat your stack traces 🥞

v1.0.0-rc.3

Update dependencies opentelemetry, opentelemetry_api, and opentelemetry_exporter to version 1.0.0-rc.3 and bump the version of this project to match.

v0.5.3

Breaking changes

• Removes the simple_trace decorator.

v0.5.2

Updates to otel 5.0

Breaking changes with opentelemetry 0.5.0:

You'll need to change ot_batch_processor to otel_batch_processor in your config. For example:

config :opentelemetry,
  processors: [
-    ot_batch_processor: %{
+    otel_batch_processor: %{
      exporter:
        {OpenTelemetry.Honeycomb.Exporter,
         write_key: Map.fetch!(System.get_env(), "HONEYCOMB_KEY"), dataset: "dataset_name"}
    }
  ]

If you're using OpenTelemetry.Span.set_attribute/2 or OpenTelemetry.Span.set_attributes/1, they now take the span context you want to set attributes on as the first argument. If you have existing wrapper functions, you can updated them to maintain the same functionality.

-  def set_attribute(key, value), do: OpenTelemetry.Span.set_attribute(key, value)
+  def set_attribute(key, value) do
+    ctx = Tracer.current_span_ctx()
+    Span.set_attribute(ctx, key, value)
+  end

-  def set_attributes(attrs), do: OpenTelemetry.Span.set_attributes(attrs)
+  def set_attributes(attrs) do
+    ctx = Tracer.current_span_ctx()
+    Span.set_attributes(ctx, attrs)
+  end

v0.5.1

handle nils as well as missing objects
