For this specific case, it may be an issue with choosing a version for the opentelemetry modules. Those are generally released as an entire collection that should be used at the same release date versions. If I upgrade go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp from v0.41.0 to v0.42.0, the upgrade proceeds just fine.

Does go get -x shed any more light on what's happening? I'm currently bisecting.

Bisect starting at 9088c69 (just tried to find something before/around the 1.20 branching) points to a094a82 which seems plausible.

go get -x shows this for me before hanging:

What does go get -v report? (It will probably be long and cyclic, so you can cut it at the point where it repeats.)

-v doesn't print anything

This turns out to be a really easy fix. The only hard part is the regression test.

modload.readModGraph had been assuming that cycles are impossible when loading the pruned part of the module graph, but in go get we selectively unprune parts of the graph in order to follow upgrades, and that unpruning can reintroduce cycles that we then need to break.

Change https://go.dev/cl/499195 mentions this issue: cmd/go/internal/modload: break more cycles in readModGraph

Nasfame pushed a commit to golangFame/go that referenced this issue Jun 4, 2023
Before CL 471595, modload.readModGraph in module with graph pruning
enabled only ever chased down transitive dependencies of unpruned
roots, so pruned dependencies couldn't cause cycles and we didn't
need to dedup them in the loading queue.

However, in 'go get' we are now passing in a set of upgraded modules
to unprune, and those upgraded modules can potentially contain cycles,
leading to an infinite loop during loading.

We have two options for a fix: we could either drop the 'unprune'
check in the enqueue operation (and instead expand the 'unprune'
requirements in a separate pass, as we do in workspace mode), or we
could check for cycles for all modules (not just the ones that are
naturally unpruned). The latter option makes it clearer that this
process must terminate, so we choose that.

(It may be possible to clean up and simplify the workspace-mode case
now that we are passing in the 'unprune' map, but for now we're
looking for a minimal fix for the Go 1.21 release.)

Fixes golang#60490.
