  • Updated agent release workflow to reference reusable workflow.

Updated onResolved instrumentation hook to only be called the first time we see a specific module filepath resolved.

Removed tracer.segment in place of direct usage of context manager.

Fixed an issue where multiple calls to instrumentLoadedModule resulted in re-instrumenting the same module.

Fixed issue where instrumentLoadedModule would return true even if the instrumentation handler indicated it did not apply instrumentation.

Added support metrics for tracking when instrumentation was applied per module.

• Supportability/Features/Instrumentation/OnResolved/<module-name>
• Supportability/Features/Instrumentation/OnResolved/<module-name>/Version/<major version>
• Supportability/Features/Instrumentation/OnRequire/<module-name>
• Supportability/Features/Instrumentation/OnRequire/<module-name>/Version/<major version>

Fixed issue where expected status code ranges would not be parsed until ignored status codes were also defined.

Added an input changelog_file to pass in name of changelog. This defaults to NEWS.md but some repos use CHANGELOG.md

Added reusable prepare-release workflow that can be referenced in all other newrelic Node.js repositories.

Runs versioned tests for external modules against tests defined in the external repository instead of tests published in npm modules.

Added a reusable workflow to automatically add issues to the Node.js Engineering Board when created.

Added CI job to update system configurations with new agent version on release.

Moved methods.js under bluebird versioned test folder.

Added onResolved instrumentation hook to apply instrumentation prior to module load.

This hook fires after the module filepath has been resolved just prior to the module being loaded by the CommonJS module loader.

Fixed issue where recordConsume was not binding consumer if it was a promise

Pinned mongo versioned tests up to 4.2.0 until we can address #982

Introduced a context management API to be used in place of manually calling tracer.segment get/set.

parseProcCPUInfo and parseProcMeminfo now check for null input prior to processing.

Updated README to favor using -r to load the agent vs require('newrelic').

Updated @newrelic/test-utilities to 6.1.1 and applied a global sampling value of 10 for versioned tests.

Migrated utilization unit tests from mocha to tap.

Migrated logger unit tests from mocha to tap.

Cleaned up or added future removal comments for several deprecation warnings.

Added a script and corresponding CI job that will check for PRs that have been merged and not release and notify the team in a private slack channel.

Updated the versioned test runner to always run against minor versions.

Fixed a high severity npm audit failure.

Added full support for Fastify v2 and v3. Fastify instrumentation is now GA.

• Removed fastify feature flag.
• Instrumented Fastify routes by wrapping addHook.
• Added middleware mounting for fastify v3.
• Fixed capturing of mount point for middleware naming.
• Fixed the WebFramework spec definitions for Fastify middleware and route handlers to properly retrieve the IncomingMessage from a request object.
• Added proper definition to middleware handlers so that the relationship to consecutive middleware and route handler are siblings and not direct children.

Added experimental instrumentation for the undici http client behind a feature flag.

To enable undici support, add the following into your config: { feature_flag: { undici_instrumentation: true } }. The support for undici client is Node.js 16.x as it takes advantage of the diagnostics_channel. Lastly, you must be using v4.7.0+ of the undici client for any of the instrumentation to work.

Note: There are currently some state issues if requests to an app are made with keep alive and you have multiple undici requests being made in parallel. In this case, set feature_flag: { undici_async_tracking: false } which avoids these state issues at the cost of some broken segment nesting.

Deprecation Warning: Cross Application Tracing (CAT) has been deprecated and will be removed in a future major release. For applications that explicitly disable Distributed Tracing (DT) to leverage CAT, we recommend migrating to DT to avoid loss of cross-service visibility.

• Disables CAT by default. You must explicitly enable CAT along with turning off DT.
• Adds a deprecation warning when CAT is enabled and active (DT disabled).

Fixed issue with clearTimeout that could result in dropping parent segments or spans. This bug resulted in some MongoDB calls being dropped from Transaction Traces and Distributed Traces (spans): https://github.com/newrelic/node-newrelic/issues/922.

Removed warnings from agent tests for no-var eslint rule.

Added support for Cassandra driver v4.0.0 and above.

Fixed issue where DT headers would not be processed by transaction-shim.handleCATHeaders() when CAT was explicitly disabled. This primarily impacts amqplib instrumentation.

Transitioned aws-lambda.test.js to use Tap over Mocha.

Removed warnings from agent for no-var eslint rule.

Refactored transaction-shim, http and http-outbound to use centralized CAT methods in util/cat

Replaced http-outbound test call to use example.com to avoid unpredictable connection resets.

Migrated sql query parser tests to tap

Added more API usage examples.

Added a README to the examples/ folder discussing how to use the examples.

Fixed message-shim test assertion to avoid flakiness based on precision differences(ms vs ns)

Applied new lint rules barring the use of var and preferring the use of const wherever possible.

Enabled Distributed Tracing (DT) by default.

• Added ability to configure the maximum number of spans that can be collected per minute via span_events.max_samples_stored and environment variable NEW_RELIC_SPAN_EVENTS_MAX_SAMPLES_STORED.
• Added supportability metric SpanEvent/Limit.

Added support for properly setting the host and port for clustered MongoDB requests.

Fixes issue where .fastify and .default properties would be missing from the fastify export when instrumented.

Instrumentation now sets .fastify and .default properties to the wrapped fastify export function for fastify v3.

Added the following environment variables for the corresponding configuration items:

• config item: transaction_events.max_samples_stored env var: NEW_RELIC_TRANSACTION_EVENTS_MAX_SAMPLES_STORED

• config item: custom_insights_events.max_samples_stored env var: NEW_RELIC_CUSTOM_INSIGHTS_EVENTS_MAX_SAMPLES_STORED

• config item: error_collector.max_event_samples_stored env var: NEW_RELIC_ERROR_COLLECTOR_MAX_EVENT_SAMPLES_STORED

Converted several unit tests to use the tap API.

Changed assertions for two HTTP error message tests to work with all versions of Node.js.
