open-telemetry/opentelemetry-go-contrib#8268 removed WithRouteTag:

docker-otel-lgtm/examples/go/main.go

Line 73 in 03c8865

handler := otelhttp.WithRouteTag(pattern, http.HandlerFunc(handlerFunc))

I'm not familiar with what the changes to maintain the status quo would be though.

seems we can just remove it (Deprecated: spans are automatically annotated with the route attribute.)

will be fixed in #1025

[zeitlinger]

This PR should not be merged yet: upgrading otelhttp from v0.64.0 to v0.65.0 removes otelhttp.WithRouteTag (deleted, not just deprecated), which we rely on to set the http.route span attribute.

The claimed automatic route extraction from http.Request.Pattern (Go 1.22+) does not work in either v0.64.0 or v0.65.0 when otelhttp.NewHandler wraps a ServeMux. The http.route attribute is read in RequestTraceAttrs at span creation time — before the ServeMux has routed the request and populated r.Pattern. The fix (PR #7192) has landed on main but has not shipped in a release yet.

Upgrading now would cause a compile error (since we use WithRouteTag) and break the oats examples/go acceptance test (TraceQL query for http.route returns no traces).

We should wait for an otelhttp release that includes the fix from #7192.

[martincostello]

The tests fail and prevent merging anyway, so there's no harm in leaving auto-merge enabled until renovate updates this PR to a newer version with the fix.

[zeitlinger]

Good point. Once an otelhttp release ships that includes the fix from open-telemetry/opentelemetry-go-contrib#7192, the upgrade should be straightforward:

1. Remove the handleFunc wrapper and WithRouteTag call in examples/go/main.go
2. Register handlers directly: mux.HandleFunc("/rolldice", rolldice)
3. The http.route attribute will be set automatically from r.Pattern after the ServeMux routes the request

That's it — the otelhttp.NewHandler(mux, "/") wrapping stays the same.

[martincostello]

The referenced PR was merged months ago, and the merge commit has these tags on it, which suggests it should work with at least one stable release already?

If not, do they need poking to ship a fix?

If not, do they need poking to ship a fix?

let me look into that

[zeitlinger]

Update: the fix from #7192 is included in v0.65.0, but it only fixes the span name, not the http.route attribute. The root cause is that otelhttp.NewHandler(mux, "/") calls RequestTraceAttrs before the ServeMux routes the request, so r.Pattern is empty at that point. After routing, otelhttp updates the span name but never sets http.route as a span attribute — this is an upstream bug (see open-telemetry/opentelemetry-go-contrib#8107).

Workaround (committed in 1dd6770): wrap individual route handlers instead of the whole mux:

mux.Handle("/rolldice", otelhttp.NewHandler(http.HandlerFunc(rolldice), "/rolldice"))

This way the ServeMux routes first, populates r.Pattern, and otelhttp correctly reads it in RequestTraceAttrs to set http.route.

The oats examples/go acceptance test passes with this approach. This PR should be ready to merge once CI is green.
