feat(otel): OTLP HTTP exporter for free-threaded OTLP export#156
Merged
Conversation
Add an opentelemetry_exporter_protocol config (grpc|http, default grpc) and an otl-http extra (opentelemetry-exporter-otlp-proto-http, no grpcio) so OTLP trace export works on free-threaded Python; repoint otl to the grpc exporter package.

…xtra Add opentelemetry_exporter_protocol (default grpc, unchanged behavior) and a grpcio-free otl-http extra (opentelemetry-exporter-otlp-proto-http) so OTLP trace export works on free-threaded Python. bootstrap() picks the aliased exporter by protocol and warns naming the right extra when it is absent; the insecure warning is gRPC-only. otl now pulls the grpc exporter package directly.

Install otl-http on both ft legs and have ft_smoke.py bootstrap a protocol=http OpenTelemetryInstrument (grpc/grpcio stays absent). Verified on real 3.13t and 3.14t interpreters. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add otl-http to the free-threading matrix, document the api/sdk/exporter guards plus protocol selection in instruments.md, clear the OTLP-http deferral, and note it in 1.3.0. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Summary
otlwas the last observability surface with no free-threaded story — its OTLP exporter goes over gRPC (needsgrpcio, no ft wheels). Adds an HTTP-exporter path. Full rationale:planning/changes/2026-07-19.02-otlp-http-exporter.md; shape decision:planning/decisions/2026-07-19-otlp-http-exporter-shape.md.What changed
