v1.55.0

Summary

With the release of Go 1.21, this dd-trace-go release drops support for Go version 1.18 and older, following our Go support policy. This minimum supported Go version for this library is now Go 1.19.

This release adds the contrib/IBM/sarama package to support for tracing the IBM/sarama Kafka library.

The Data Streams Monitoring Go library has been incorporated into this library. The feature can be enabled by setting the DD_DATA_STREAMS_ENABLED environment variable to true.

This release introduces a debug mode for the tracer to help identify long-lived or abandoned spans, which can lead to increased memory usage. It can be enabled with the WithDebugSpansMode tracer option or by setting environment variable DD_TRACE_DEBUG_ABANDONED_SPANS =true.

This release also includes several bug fixes and performance improvements:

  • Fix a bug in contrib/database/sql which incorrectly cached contexts.
  • Resolve a data race in contrib/net/http.
  • Reduce the memory allocated during initialization of the contrib/google.golang.org/api package.
  • Improve the latency of W3C traceparent header validation.

Summary

In this release, Application Performance Monitoring (APM) adds partial flushing beta support, it enables flushing of partially finished traces. Partial flushing is disabled by default, it can be enabled via WithPartialFlushing or by setting DD_TRACE_PARTIAL_FLUSH_ENABLED to true. See the docs for more details.

What's Changed

This release includes several new features for various APM integrations, including a new opt-in service naming schema, improvements to contrib/gocql and the ability to add HTTP headers to traces in several integrations. In addition, there are a number of small bug fixes and improvements for APM, ASM and the Profiler.

Application Security Management (ASM) no longer requires CGO to be compiled. The appsec build tag is still required for now for a progressive roll-out and will be removed in the next few months. Read more in below's ASM section.

Application Performance Monitoring (APM)

Peer Service naming schema

This release introduces a new opt-in service naming approach, aiming to make service names more consistent. You can opt-in to this new service naming setting DD_TRACE_PEER_SERVICE_DEFAULTS_ENABLED="true" and DD_TRACE_REMOVE_INTEGRATION_SERVICE_NAMES_ENABLED=true.

For fine-tuned control of your service names, you can configure DD_TRACE_PEER_SERVICE_MAPPING, providing comma-separated key:value mapping rule pairs, similar to how DD_SERVICE_MAPPING is configured today.

HTTP Header Tags

This release includes a new feature to add HTTP headers as trace tags for several integrations:

  • contrib/emicklei/go-restful
  • contrib/gin-gonic/gin
  • contrib/go-chi/chi.v5
  • contrib/go-chi/chi
  • contrib/gorilla/mux
  • contrib/labstack/echo.v4
  • contrib/labstack/echo
  • contrib/urfave/negroni
  • contrib/net/http

The feature can be configured globally with the WithHeaderTags option to tracer.Start(), or individually for each integration with the WithHeaderTags options available in each integration package. It accepts a map of case-insensitive header keys to tag names and automatically applies matching header values as tags on traces, e.g. CASE-insensitive-Header:my-tag-name,User-ID:userId,My-Header-And-Tag-Name. Also accepts entries without a specified tag name that are automatically mapped to tags of the form http.request.headers.<header-name>.

APM Changelog

Application Security Management (ASM)

We're happy to release the first version of ASM for Go that no longer requires CGO. This reduces the setup requirements to the bare minimum for Go development: the Go toolchain and nothing more!
Note that even if you disable CGO with CGO_ENABLED=0, the resulting compiled program will still be dynamically linked against the C library, libm, and libdl. Already existing ASM users are not impacted by this new implementation and can upgrade to this version transparently, as these libraries were already required by the previous implementation using CGO.

This release also includes the ability to configure at run time your HTTP protection behaviour at https://app.datadoghq.com/security/configuration/asm/protection-behaviour

  • internal/appsec: remove unnecessary remoteconfig updates specifications by @Hellzy in #2084
  • appsec: integrate the new purego-based go-libddwaf by @Julio-Guerra in #2090
  • appsec: remotely configurable HTTP protection behaviour by @Hellzy in #2044

Profiling

  • contrib/database/sql: properly annotate DB operations with execution trace tasks by @nsrip-dd in #2060
  • profiler: Add profiler.enabled tag by @felixge in #2065
  • profiler: Reduce execution trace period to 15min by @felixge in #2091

v1.52.0

What's Changed

Application Security Management (ASM) updated its default blocking page templates to get rid of UTF-8 characters (HTML) and minify the content (JSON). The security rules have also been updated to the latest version, which introduces a new rule type for rules related to specific security scanners.

Application Performance Monitoring (APM) adds several new features, including support for confluent-kafka-go/v2/kafka, a WithResourceNamer option in contrib/go-chi/chi.v5, and support for the sql comment extract implementation. It also contains a few fixes, including introducing a fallback to dynamic service names if no global is found in contrib/google.golang.org/grpc, and removes the restriction requiring a call to Register before Open in contrib/database/sql.

v1.51.0

⚠️ v1.51.0 contains a regression where a small number of integrations was not configured properly with environment variables, if they were initialized before starting the tracer. Such integrations include contrib/google.golang.org/grpc. Please upgrade to v1.52.0 if you're experiencing issues.

What's Changed

Application Performance Monitoring (APM) fixes a few minor OpenTelemetry-related bugs with W3C trace context propagation, 128 bit trace ids propagation, and the use of the Datadog OTel API. There are also bug fixes in contrib/database/sql, contrib/go-redis/redis.v8, and contrib/gomodule/redigo. It also improves span and service naming across several library integrations. Note that this release adds a deprecation notice to contrib/labstack/echo.
There are also several new features, including support for the redis/go-redis.v9 tracing integration and a new WithErrorCheck option in contrib/aws/aws-sdk-go.

Application Security Management (ASM) now allows users to configure their own custom security rules. These custom security rules get added to the list of security rules used by the In-App WAF. This release also includes a couple of bug fixes.

Summary

Application Security Management (ASM) now provides an In-App WAF (Web Application Firewall) which allows you to block suspicious HTTP requests based on your security rules. The main difference with a classic WAF comes from the fact we leverage the full run-time application context and not only the raw wire-format HTTP protocol payloads (eg. the actual Go values parsed from the raw HTTP request). This release also allows you to remotely configure your ASM configuration on the fly, without redeploying your Go services. This makes it possible to customize the In-App WAF rules to apply to each of your services and configure them in blocking mode. You can read more about our new In-App WAF feature in our documentation, and check out the new In-App WAF configuration page.

Application Performance Monitoring (APM) has added several new larger features: support for 128-bit trace IDs, as well as an Open Telemetry compatible tracer provider API. Note this wrapper is a "beta" feature, it may contain bugs and is not recommended for production use yet.

Summary

Application Performance Monitoring (APM) ships various new features and bug fixes such as support for elastic/go-elasticsearch/v8 and for dimfeld/httptreemux/v5. Additional features include new tags for mssql in database/sql, and new tags for mgo. This release also includes a bug fix to how baggage is propagated when using W3C trace context injection/extraction.

Application Security Monitoring (ASM) adds support for multiple IP-related HTTP headers as well as fixing HTTP status code reporting for blocked users in labstack/echo.

Telemetry information is now enabled by default, to disable set DD_INSTRUMENTATION_TELEMETRY_ENABLED to false. Additional information can be found here.

Breaking Changes

This change fixes our lookup of OS name in linux systems that is used for our startup logging. If you are parsing those startup logs and relying on the value of os_name you may experience a breaking change as the value may shift from "Linux (Unknown Distribution)" to the now correctly identified OS name.

The PprofDiff function is deprecated and will be removed from the profiler package in the next release.
