v2.0.0 (2024-10-30)

  • @logfire.instrument() no longer needs source code by @alexmojaki in #543. BREAKING CHANGES caused by this:
    • Functions decorated with @logfire.instrument() and functions nested within them can now be auto-traced unlike before. Use @logfire.no_auto_trace anywhere on functions you want to exclude, especially the instrumented function.
    • Decorated async generator functions won’t support the .asend method properly - the generator will only receive None. But instrument shouldn’t be used on generators anyway unless the generator is being used as a context manager, so new warnings about this have been added. See https://logfire.pydantic.dev/docs/guides/advanced/generators/#using-logfireinstrument

Other fixes

v0.50.1 (2024-08-06)

(Previously released as v0.50.0, then yanked due to https://github.com/pydantic/logfire/issues/367)

  • BREAKING CHANGES: Separate sending to Logfire from using standard OTEL environment variables by @alexmojaki in https://github.com/pydantic/logfire/pull/351. See https://logfire.pydantic.dev/docs/guides/advanced/alternative_backends/ for details. Highlights:
    • OTEL_EXPORTER_OTLP_ENDPOINT is no longer just an alternative to LOGFIRE_BASE_URL. Setting OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_TRACES_ENDPOINT, and/or OTEL_EXPORTER_OTLP_METRICS_ENDPOINT will set up appropriate exporters in addition to sending to Logfire, which must be turned off separately if desired. These are basic exporters relying on OTEL defaults. In particular they don’t use our custom retrying logic.
    • LOGFIRE_BASE_URL / logfire.configure(base_url=...) is now only intended for actual alternative Logfire backends, which are currently only available to Logfire developers, and unlike OTEL_EXPORTER_OTLP_ENDPOINT requires authenticating with Logfire.
    • Pending spans are only sent to logfire-specific exporters.
  • Add capture_statement to Redis instrumentation by @Kludex in https://github.com/pydantic/logfire/pull/355

v0.40.0 (2024-06-04)

  • BREAKING CHANGE: The processors parameter of logfire.configure() has been replaced by additional_span_processors. Passing processors will raise an error. Unlike processors, setting additional_span_processors to an empty sequence will not disable the default span processor which exports to Logfire. To do that, pass send_to_logfire=False. Similarly metric_readers has been replaced by additional_metric_reader. By @alexmojaki in https://github.com/pydantic/logfire/pull/233
  • Improve error raised when opentelemetry.instrumentation.django is not installed by @deepakdinesh1123 in https://github.com/pydantic/logfire/pull/231
  • Handle internal errors by @alexmojaki in https://github.com/pydantic/logfire/pull/232

v0.39.0 (2024-06-03)

Add new methods for easier integration in https://github.com/pydantic/logfire/pull/207:

  • instrument_flask
  • instrument_starlette
  • instrument_aiohttp_client
  • instrument_sqlalchemy
  • instrument_pymongo
  • instrument_redis

v0.38.0 (2024-05-31)

BREAKING CHANGE: Calling logfire.info, logfire.error, logfire.span etc. will no longer automatically configure logfire if it hasn’t been configured already. Instead it will emit a warning and not log anything. Users must call logfire.configure() before they want logging to actually start, even if they don’t pass any arguments to configure and all configuration is done by environment variables. Using integrations like logfire.instrument_fastapi() before calling configure will also emit a warning but it will still set up the instrumentation, although it will not log anything until configure is called.
