Python agent release notesRSS

Notes

This release of the Python agent includes minor bug fixes.

Bug Fixes

• Fix incorrect wrapper in grpc instrumentation.

_MultiThreadedRendezvous._next was wrapped with the instrumentation designed for _MultiThreadedRendezvous.result. This issue has been resolved as of this agent version.

Notes

This release of the Python agent updates transaction naming for Starlette and FastAPI, and includes bug fixes.

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site.

Improved Features

• Updated transaction naming for middleware in Starlette and FastAPI

  The transaction naming hierarchy has been updated for Starlette and FastAPI applications. The web transaction name is named after the route handler, or after middleware if an exception is raised in the middleware.

Bug Fixes

• RuntimeError for imports occurring on a background thread

  A RunTimeError was being raised in the event of imports occurring on a background thread during iteration over sys.modules. This issue has been resolved in this agent version.

• Fixed region aware license key default host setting

  This agent version contains a fix for setting the default host value based on the license key for EU license keys. Setting the host manually will still override the default host value set by the license key.

Notes

This release of the Python agent adds instrumentation for Starlette and FastAPI.

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site.

Deprecations

• Python 3.5 has been deprecated

  Python 3.5 has reached end of life and support will be dropped in a future release. Using the agent with Python 3.5 will generate a deprecation warning. Updating Python versions is recommended.

New Features

• Adds Starlette framework instrumentation

  Starlette applications will now be automatically instrumented. Transaction data will be collected and recorded for application routes, background tasks, exception handlers, and installed middleware. Exception logging has also been added.

• Adds FastAPI framework instrumentation

  FASTAPI applications will also now be automatically instrumented. See above for instrumentation details.

Bug Fixes

• Fix deprecation warning for find_loader in python 3

  Using the agent no longer generates a deprecation warning for find_loader. The call to find_loader has been replaced with find_spec.

Notes

This release of the Python agent adds support for Python 3.9 and includes bug fixes.

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site.

Bug Fixes

• Duplicate warnings were logged repeatedly when using the agent with Python 3

  The agent internally suppressed any warnings generated when data was sent via HTTP to New Relic in a way that caused the warning filters to mutate. This caused the cache of already printed warnings to be cleared, resulting in duplicate warnings after every data harvest. The agent no longer mutates the process warning filters on a background thread, resulting in consistent warning behavior.

• AttributeError when passing an inactive transaction into ExternalTrace.generate_request_headers

  When passing an inactive transaction into ExternalTrace.generate_request_headers, an AttributeError was generated. This agent version contains additional validation for the transaction argument in ExternalTrace.generate_request_headers.

• The infinite tracing host configuration value did not have sufficient validation

  When passing a URL or other invalid host to the infinite tracing host configuration, the agent accepted this value unchecked to use in the host parameter for later connections via grpc. The agent now validates this configuration and attempts to correct for invalid hosts if it is able to detect the host. If a host is not detected, the agent automatically falls back to infinite tracing disabled and logs an error.

Notes

This release of the Python agent adds instrumentation for uvicorn and asyncpg.

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site.

New Features

• Adds uvicorn instrumentation

  ASGI applications are now automatically wrapped when using the uvicorn ASGI server.

• Adds asyncpg instrumentation

  Support has been added for recording database transactions when using asyncpg database client module for PostgresSQL.

Improved Features

• Adds db.operation attribute

  A new attribute, db.operation, was introduced for datastore traces. This value is recorded only when db.statement is not reported, and represents an operation triggered by methods other than running a DB statement.

Notes

This release of the Python agent adds new ASGI apis and upgrades wrapt.

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site.

New Features

• Adds support for ASGI applications via built in APIs

  ASGI applications can now be timed via middleware-like API calls. Browser monitoring JS is automatically injected into HTML pages by the ASGI browser monitoring middleware for instrumented applications. See the asgi_application docs for details on API usage.

• Upgrades wrapt to 1.12.1

  This version of the agent ships with wrapt 1.12.1.

Notes

This release of the Python agent includes bug fixes.

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site.

Bug fixes

• Fix invalid payloads generated when using serverless mode

  When using serverless mode on the Python Agent versions v5.16.0 and v5.16.1, invalid serverless/lambda payloads were generated. The agent now generates the proper payloads in serverless mode.

Notes

This release of the Python agent introduces manylinux wheels and includes bug fixes.

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site.

Bug fixes

• Data was erroneously discarded when an HTTP protocol error occurred

  When an unexpected HTTP error occurred (such as a timeout), data was erroneously discarded. Data is now downsampled and retransmitted when an HTTP protocol error occurs.

• Error when installing with an incompatible setuptools_scm version

  The version requirements were not correctly set for the setuptools_scm build time requirement, which may have resulted in an error at installation. The version requirements for setuptools_scm are now set appropriately.

Notes

This release of the Python agent changes the internal http client from requests to urllib3, updates logging, and includes bug fixes.

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site.

Improved Features

• The NewRelicContextFormatter now records extras

  When using the NewRelicContextFormatter log formatter, extras are now automatically captured and recorded in the New Relic agent logs product.

• The agent now internally uses urllib3

  The python agent previously used requests as its http client. The agent now uses urllib3 internally for HTTP communication with New Relic data ingest services.

Bug fixes

• Fix gRPC application crash when credentials are supplied

  When using the credentials argument, the agent's built in gRPC instrumentation caused an application crash. This crash has been fixed.

• Fix Tornado framework crashes when finish is called from a different task

  When finish is called from a different task, applications using the Tornado framework may crash. This crash has been fixed.
