In CI, if we're going to run unit tests under the race detector, is there any value in running unit tests again _without_ the race detector? I'm inclined to say yes, since in production customers won't be running with the race detector enabled; but it feels like the answer should be no since t

I suspect that this kind of performance issue may be fixed by better compiler optimisation in the future (I think should be possible for the compiler to notice that the string doesn't escape and pass a pointer to the byte slice as the string argument). On 15 September 2017 at 10:36, Peter Waller

Re: [go-nuts] Re: Bytconv where art thou

Because of the immutability of the string, constructing a string on a byte slice requires allocating and copying the bytes. Once you've got the string, it's "free" to pass around. If you've already got strings, everything is fine. But if you're reading the data from IO, you're probably starting wi
