Fix Synapse passthru spans finishing before status code is available #10478

ValentinZakharov · 2026-01-30T00:16:26Z

What Does This Do

Fixed flaky Synapse passthru tracing by changing when we finish the HTTP span.
responseReady and responseReceived may be called before the HttpResponse (and status code) is available.
Instead of removing the stored context and finish span of the first callback, we keep the context until we see the real response status (or error), then finish the span once.

Motivation

Test test passthru request is traced was sometimes failing with, because the span was finishing too early, before status code was known

Additional Notes

With the passthru/NIO transport, SourceHandler.responseReady() and TargetHandler.responseReceived() can be called multiple times for the same connection
The first call can happen while the response is still null, and the actual 200 OK is set later.
Previously we removed the context and finished the span on that first call, so the later callback couldn’t tag the span

Contributor Checklist
