feat(pinner): close pinner before repo on shutdown#11296
Conversation
The pinner's streaming goroutines hold a reference to the backing datastore, and pebble panics on use after Close. Before this change the panic was recovered inside the pinner (see ipfs/boxo#1146) and the symptom was only a transient log trace on daemon exit, but the race remained. Register a new fx OnStop hook that calls pinner.Close before the repo (and therefore the datastore) closes. Close drains all in-flight stream goroutines, so the datastore is closed only after the pinner is fully quiesced. Bumps boxo to pick up Pinner.Close from ipfs/boxo#1150. Fixes #11292

Problem
The pinner's streaming goroutines hold a reference to the backing datastore, and pebble panics on use after Close. Before this change the panic was recovered inside the pinner (see ipfs/boxo#1146) and the symptom was only a transient log trace on daemon exit, but the race remained.
Fix
This PR wires the proper cleanup
Register a new fx OnStop hook that calls pinner.Close before the repo (and therefore the datastore) closes. Close drains all in-flight stream goroutines, so the datastore is closed only after the pinner is fully quiesced.
