[go-nuts] multiple vendored x/net causing trouble (x/net/trace panic)

This panic has caused me trouble many times over the last year: panic: http: multiple registrations for /debug/requests goroutine 1 [running]: net/http.(*ServeMux).Handle(0x5c47ba0, 0x511cbc5, 0xf, 0x5223160, 0x515f730) /usr/local/go/src/net/http/server.go:2353 +0x239

[go-nuts] Re: [go/types] Implements doesn't work for types from different packages when the interface signature has types from the package where the interface lies.

This library are not supposed to be used that way. Importer should be used directly: package main import ( "fmt" "go/importer" "go/types" ) var imprt = importer.For("source", nil) func main() { p1, err := imprt.Import("awesome/pkg1") if err != nil { panic(err) } p2,

[go-nuts] Re: go 1 on Ubuntu 18.04

Updating Go is simply a matter of removing old Go installation directory and replace it with new one. For your particular use case - Remove the go folder under /usr/lib (the /usr/bin/go just holds the binary). Install the new go version to /usr/local as mentioned on golang installation

Re: [go-nuts] Re: I don't know about callbacks in Golang

The first approach with a func argument to a func can be synchronous (which is what I was thinking at the time) or it could be asynchronous by using the go keyword on the callback. Matt On Monday, May 7, 2018 at 11:48:20 AM UTC-5, florent giraud wrote: > > ok matthew so what you propose is

[go-nuts] Behavior of DotReader

Hey guys, I am not quite sure whether the following behavior is intended or not. Therefore, I am seeking for your advice. Using DotReader's Read() function from the textproto package requires me to provide an predefined buffer to fill in processed data (as usual for Read() functions). Let's

You are probably right about go get. I was pulling the repos into my workspace so I could check out the code more easily. That, plus just informing the user as to what is involved, is why you might want to list dependencies. Gradients are coming soon to oksvg. On Monday, May 7, 2018 at

[go-nuts] Re: I don't know about callbacks in Golang

Callbacks in Go can be done with a func argument to a func, or a similar effect can be made with channels by triggering a callback action by waiting on a blocking channel in the application. This Wikipedia article describes the pattern:

Re: [go-nuts] cross-compile mac to linux

It was specifically stated that the code was CGO - this approach won’t work unless there is a C compiler that is crosscompile enabled installed already - I’m guessing the question is how to do that. In my experience the (by far) easiest way to do this is to set up a (Docker) container or a VM

[go-nuts] Re: I don't know about callbacks in Golang

To use callbacks in Go you must follow Functional Programming rules about shared data. In simple terms, you cannot share data. You can pass pointers to shared data structures, and likely will have to but as soon as you start using also goroutines you will end up with race conditions. To solve

There is semantic difference between callback passed for continuation of asynchronous action, and closure/function passed as algorithm parameter. sort.Slice and sync.Map.Range both accepts function/closure as algorithm parameter, not as callback. -- You received this message because you are

Steve — thanks for your impressions. I’ll definitely contact you directly when I get around to trying to integrate rasterx — I haven’t even had a chance to look at it all, but a first question is when you expect it to be stable and reasonably feature-complete? e.g., one of the main things I
