closecheck
closecheck is a static code analyzer which checks whether a return value that implements io.Closer is correctly closed
Install
You can get closecheck by go get command.
$ go get -u github.com/dcu/closecheck
QuickStart
$ closecheck package/...
Analyzer
closecheck checks that a returned io.Closer is not ignored since that's a common cause of bugs and leaks in Go applications. Specially when dealing with *http.Response.Body
For example, the following code is reported as an error:
_, err := http.Get("https://www.google.com")
...
Because the response body must be closed.
The checker detects whether the returned struct has a field that implements io.Closer or not. In the previous case the *http.Response struct has a field called Body which implements io.Closer
