Klaus Post ebc6c9b498 Fix tracing send on closed channel (#18982) ... Depending on when the context cancelation is picked up the handler may return and close the channel before `SubscribeJSON` returns, causing: ``` Feb 05 17:12:00 s3-us-node11 minio[3973657]: panic: send on closed channel Feb 05 17:12:00 s3-us-node11 minio[3973657]: goroutine 378007076 [running]: Feb 05 17:12:00 s3-us-node11 minio[3973657]: github.com/minio/minio/internal/pubsub.(*PubSub[...]).SubscribeJSON.func1() Feb 05 17:12:00 s3-us-node11 minio[3973657]: github.com/minio/minio/internal/pubsub/pubsub.go:139 +0x12d Feb 05 17:12:00 s3-us-node11 minio[3973657]: created by github.com/minio/minio/internal/pubsub.(*PubSub[...]).SubscribeJSON in goroutine 378010884 Feb 05 17:12:00 s3-us-node11 minio[3973657]: github.com/minio/minio/internal/pubsub/pubsub.go:124 +0x352 ``` Wait explicitly for the goroutine to exit. Bonus: Listen for doneCh when sending to not risk getting blocked there is channel isn't being emptied.		2024-02-06 08:57:30 -08:00
