spakky-tracing 6.4.0

Distributed tracing abstraction for Spakky Framework

Spakky Tracing

Distributed tracing abstraction for Spakky Framework.

Installation

pip install spakky-tracing

Features

• TraceContext: W3C Trace Context Level 2 compatible trace context with contextvars support
• ITracePropagator: Abstract interface for trace context propagation across service boundaries
• W3CTracePropagator: Built-in W3C traceparent header propagator
• Async-safe: contextvars-based context propagation, isolated per asyncio task
• Zero external dependencies: Pure Python implementation, depends only on spakky core

Quick Start

Create and Propagate Trace Context

from spakky.tracing.context import TraceContext

# Start a new root trace
ctx = TraceContext.new_root()
TraceContext.set(ctx)

# Access current trace
current = TraceContext.get()
print(current.to_traceparent())
# 00-0af7651916cd43dd8448eb211c80319c-b7ad6b7169203331-01

# Create a child span
child = current.child()
TraceContext.set(child)

Parse Incoming Trace Headers

from spakky.tracing.context import TraceContext

header = "00-0af7651916cd43dd8448eb211c80319c-b7ad6b7169203331-01"
ctx = TraceContext.from_traceparent(header)

Use W3CTracePropagator for Injection/Extraction

from spakky.tracing.w3c_propagator import W3CTracePropagator

propagator = W3CTracePropagator()

# Inject current trace into outgoing headers
carrier: dict[str, str] = {}
propagator.inject(carrier)
# carrier == {"traceparent": "00-...-...-01"}

# Extract trace from incoming headers
ctx = propagator.extract(carrier)
