Re: [go-nuts] How to do a cleanup of context cancelling?

I'm pretty sure that code won't code will compile as written. Firstly, http.DefaultClient.Do (req) returns two values, but c is a chan error. Secondly, the second case statement is invalid syntax (case err := f(<-c):) - you can't put a function call in here,

Re: [go-nuts] How to do a cleanup of context cancelling?

Proabably should change code to: func httpDo(ctx context.Context, req \*http.Request, f func(\*http.Response, error) error) error { // Run the HTTP request in a goroutine and pass the response to f. c := make(chan error, 1) req = req.WithContext(ctx) go func() { c <- http.DefaultClient.Do(req)
