beeline-python changelog

2.12.1 2020-03-24

Fixes

Fixes traced decorator behavior when working with generators. #106
Fixes method for detection of asyncio. #107

2.12.0 2020-03-19

Features

urllib auto-instrumentation via patch.#102
jinja2 auto-instrumentation via patch. #103

Improvements

flask auto-instrumentation now includes the route as request.route field on the root span. #104

2.11.4 2020-01-27

Fixes

Trace context headers injected with the requests middleware now reference the correct parent span. Previously, the trace context was generated prior to the wrapping span around the request call, anchoring spans generated with this trace context to the wrong span.

2.11.3 2020-01-23

Fixes

Prevent duplicate app. prefixes in trace fields. #96

2.11.2 2019-11-26

Fixes

Allows less than three fields in trace context headers.

2.11.1 2019-11-19

Fixes

Flask Middleware: AttributeError in DB instrumentation when cursor.lastrowid doesn't exist #91.

2.11.0 2019-11-18

Features

Asyncio support! The new AsyncioTracer is used instead of SynchronousTracer when the beeline is initialized from within an asyncio event loop. #87

2.10.1 2019-11-12

Traces propagated from other beelines (nodejs, go) which supply the "dataset" field in the trace context can now be handled by unmarshal_trace_context. The dataset is discarded - honoring this override will come in a later version.

2.10.0 2019-11-07

Features

awslambda middleware can now extract Honeycomb Trace context from single SNS/SQS messages. #77

2.9.1 2019-09-10

Fixes

Don't try to access self.state.span in handle_error of Flask DB middleware if there is no current_app #81.

2.9.0 2019-09-09

Improvements

Django middleware now supports instrumentation of multiple database connections. See #80.

2.8.0 2019-08-06

Features

Django, Flask, Bottle, and Werkzeug middleware can now be subclassed to provide alternative implementations of get_context_from_request (Django) get_context_from_environ (Flask, Bottle, Werkzeug) methods. This allows customization of the request fields that are automatically instrumented at the start of a trace. Thanks to sjoerdjob's initial contribution in #73.

Fixes

Django's HoneyMiddleware no longer adds a request.post field by default. This was removed for two reasons. First, calling request.POST.dict() could break other middleware by exhausting the request stream prematurely. See issue #74. Second, POST bodies can contain arbitrary values and potentially sensitive data, and the decision to instrument these values should be a deliberate choice by the user. If you currently rely on this behavior currently, you can swap out HoneyMiddleware with HoneyMiddlewareWithPOST to maintain the same functionality.
The awslambda middleware no longer crashes if the context object is missing certain attributes. See #76.

2.7.0 2019-07-26

Features

Implements add_rollup_field API used in other Beelines. See the official API reference docs for full details.

2.6.1 2019-07-02

Fixes

Python Beeline now uses the same method to compute deterministic sampling decisions as other beelines (Go, NodeJS, Ruby). Prior to the fix, Beeline-generated traces spanning multiple services implemented in Python and other languages would have sometimes arrived incomplete due to inconsistent sampling behavior.

2.6.0 2019-06-05 - Update recommended

Features

Adds new traced_thread decorator to copy over trace state to new threads. Read more in the official docs here.
Adds initial support for Werkzeug. Read about how to use it here.

Fixes

init now works after a process fork. If the beeline has already been initialized prior to the fork, it will be reinitialized if called again. Prior to this change, calling init before fork would render the beeline inoperable in the forked process(es).

2.5.1 2019-05-13

Fixes

Support parameters of type dict in the flask-sqlachemy middleware. Addresses #62.
