As I've been struggling to make this cleaner I think I have had a realization. I want to be able to trace futures which means I need to use |
Handler panics in HandlerTaskMode::Detached were incorrectly being reported as 499 (Client Closed Request) instead of 500 (Internal Server Error) in telemetry and traces. This occurred because the panic handling code called panic::resume_unwind(), which caused the request handling task to panic and trigger the disconnect guard, leading to incorrect status code assignment. Changes: - Extract panic message from JoinError and convert to HttpError - Return 500 Internal Server Error instead of propagating panic - Add integration test to verify panic handling returns proper 500 status - Preserve existing behavior for HandlerTaskMode::CancelOnDisconnect 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Add an optional "tracing" feature that enables a bridge between the tracing crate and slog, allowing users to use tracing macros while maintaining slog's structured logging and bunyan format output. Key changes: - Add optional tracing dependencies behind "tracing" feature flag - Implement SlogTracingBridge that converts tracing events to slog records - Preserve structured data types (numbers, booleans) in log output - Use proper detection with tracing::dispatcher::has_been_set() - Initialize bridge automatically when feature is enabled - Add comprehensive tests for bridge functionality The bridge maintains backwards compatibility - existing slog usage continues to work unchanged, and tracing is only available when explicitly enabled via the feature flag. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

OpenTelemetry for Dropshot
This is now version 2. It has leaned into the use of
tokio-tracingandopentelemetry-tracing.The
tracingfeature funnels tracing logs out toslogfor unified logging.The
otel-tracingfeature enables shipping traces via OTLP.They can be used together or individually.
Checklist of things that are needed (note that much of it is currently incomplete):
Known Issues
- If a handler panics, currently we get a 499 error span. I don't really like that.See #1359dtrace.conf(24) References
