1.5.0

New Features

• Add metrics.process_id to default ignored attributes
• Add support for POST /telemetry/proxy/api/v2/apmtelemetry endpoint and tracking telemetry requests.
• Add support for the /info endpoint.
• Add support for artificially throttling requests to simulate an agent under duress. Enabled dynamically via request header X-Datadog-Test-Trace-Stall-Seconds with /v0.4/trace requests or statically via the --trace-request-delay flag.
• Add unix domain socket support. Enabled via environment variable DD_APM_RECEIVER_SOCKET or command line argument --trace-uds-socket.

Bug Fixes

• Fix content length check assuming that the Content-Length header is always included in trace http requests. Some clients (like go) don't submit this header.
• Add ClientDropP0s setting to /info response.
• Handle POST /v0.6/stats requests. Only PUT was supported before.
• Decode service field in trace stats requests, it was previously omitted.

1.4.0

New Features

• Add support for distributed traces where an instrumented service sends a trace chunk where the root span has a parent not in the trace chunk.
• Build an ARM64 version of the Docker image as a multi-arch image.

1.3.3

New Features

• Better snapshot error messages for unexpected number of traces received.

Bug Fixes

• Fix not present parent_id in snapshots. It should be normalized to 0.

1.3.2

Bug Fixes

• Handle span parent_id being undefined.

1.3.1

Bug Fixes

• Normalize trace stats snapshots using all the aggregation fields. This fixes an issue where snapshots could fail due to ordering of buckets.
• Use HTTPStatusCode in trace stats snapshots. This field was missing.

1.3.0

New Features

• Add /test/session/requests endpoint to return all requests made to the test agent for a given session token.

• Add support for the /v0.6/stats endpoint. All requests made to the endpoint will be stored and can be retrieved via the /test/session/requests or /test/session/stats endpoints. Note that snapshotting for stats is not yet implemented.

• Implement trace stats snapshotting.

  Trace stats are now included in the snapshot behaviour provided by the testagent.

  Similar to traces, trace stats snapshots are output to a json file.

Bug Fixes

• Fix custom snapshot filenames. Custom filenames are not supposed to include the file extension.

1.2.1

Release Notes

v1.2.1

Bug Fixes

• Fix log messages in ddapm-test-agent-fmt.

1.2.0

Release Notes

v1.2.0

New Features

• Added ddapm-test-agent-fmt to format or validate snapshot json files.

1.1.0

Release Notes

v1.1.0

New Features

• Trace requests can now be proxied to an actual agent by passing an agent url to the test agent. This can be done by passing the --agent-url command-line option or via the DD_AGENT_URL or DD_TRACE_AGENT_URL environment variables.
• Add Python 3.10 support.
• Add support for the /v0.5/traces endpoint. Traces sent to this endpoint can be queried and snapshotted just as they can be for /v0.4/traces.

Other Notes

• Snapshots will no longer have empty meta/metrics maps included in the output.

1.0.1

Release Notes

v1.0.1

Bug Fixes

• Fix the snapshot matching algorithm which had previously assumed that trace ids would be unique across both sets of traces.
• Fix sessions returning traces from all sessions.
