Re: [go-nuts] Where is my memory in Linux?

We started this Go application by supervisor, so this Go app should be the subprocess of supervisor. Do you think it is the problem? On Saturday, February 3, 2018 at 3:18:02 AM UTC+8, Justin Israel wrote: > > > > On Sat, Feb 3, 2018, 2:21 AM Zhang Rui > wrote: > >> Hello

[go-nuts] Re: “Design Patterns: Elements of Reusable Object-Oriented Software” in Go

I would rank them mostly unused. There was a point someone made in the past how choosing between design patterns is the equivalent of choosing calling conventions for functions, I don't remember the source, but I agree with the comparison. Most of these are superseded by struct and interface

Re: [go-nuts] Where is my memory in Linux?

Thank you for your reply. No, this app doesn't use cgo. It's a pure Go application. Another go application on this VM used cgo. But it also should not launch the subprocesses. 在 2018年2月3日星期六 UTC+8上午3:18:02，Justin Israel写道： > > > > On Sat, Feb 3, 2018, 2:21 AM Zhang Rui >

Here’s my proxy example with “func (a ProxyCar) Drive()” instead of DriveCar (I didn’t think this would work), and an F-150: https://play.golang.org/p/drDDkx_e0Mp This may fix the signature difference but I see that having an interface type like you suggested for car would allow other data and

I didn't get a chance to look at all of them, but your Proxy pattern example is incorrect. The idea of a proxy is that the proxy object exposes the same interface as the underlying object, so they are substitutable. In your example, Car is concrete (meaning that callers cannot substitute any

Looks the non-omitted "true" is also a typed value of "bool" type. package main type T bool func f() T {return T(false)} func main() { switch true { case f(): // invalid case f() in switch (mismatched types T and bool) } } On Friday, February 2, 2018 at 10:11:31 AM UTC-5,

You can either use one of the existing other routers that have meddleware support or you could wrap your handlers in another handler much like this: handle("/foo",wrapHandler(rateLimiter, realHandler)) func wrapHandler(limit *ARateLimiter, handler func(http.ResponseWriter, *http.Request))
