Description

Go 1.26 ships an experimental goroutine leak profiler (GOEXPERIMENT=goroutineleakprofile). It detects goroutines blocked on channels, mutexes, or conditions that can never unblock, using GC reachability analysis. Zero runtime overhead unless actively collecting.

Available at /debug/pprof/goroutineleak when enabled.

Proposal

Once 1.27 ships with it enabled by default:

  • Add a goroutine-leak collector to ipfs diag profile --collectors (gated on the experiment being available at runtime)
  • Expose it via the existing /debug/pprof/ endpoint on the API port

This would help diagnose daemon goroutine leaks without external tooling. Useful for long-running nodes where leaked goroutines accumulate over time.

Direção de pesquisa
The issue proposes adding a goroutine leak collector to the `ipfs diag profile` command, gated on the Go experiment being available. Start by reading the Go 1.26 documentation on goroutine leak profiles and examining the existing collectors in the `ipfs diag profile` codebase (likely in a diagnostics package). Also review the `/debug/pprof/` endpoint implementation to see how to expose the new profile. The issue is waiting for Go 1.27 to enable it by default, but initial implementation can be done behind a build tag. Check if there are any linked PRs or comments for additional context.
