# unbuffered-signal-channel

**Default severity:** `warning`

The `os/signal` package uses non-blocking sends to deliver notifications. If
no receiver is immediately ready, an unbuffered channel drops the signal.
Give the channel enough capacity for the signals being handled.

## Bad

```go
ch := make(chan os.Signal)
signal.Notify(ch, os.Interrupt)
```

## Good

```go
ch := make(chan os.Signal, 1)
signal.Notify(ch, os.Interrupt)
```
