I agree. It seems to me that the problem in example 2 is deep in the architecture of the program, not just a detail of the `select` statements. The `connect` function essentially functions as a single-worker “worker pool”, storing the data in a goroutine (specifically, in the closure of the

This breaks my already fairly tenuous grasp of the progression of time; what do you mean by since "since then" when that event is a personal that is in the past (do you mean between going to sleep in the future and waking up in the past). Time [travel] is hard. On Mon, 2019-12-09 at 11:24 -0800,

Re: [go-nuts] cgo & long jump

That usage of setjmp and longjmp are pretty much banned in modern C by every linter. You can only call setjmp/longjmp within the current call stack (at least that's my understanding) - intermixing the context switch to Go would not be correct. Just have a wrapper on f2() that takes the

Re: [go-nuts] cgo & long jump

The longjmp() facility is a wild, dangerous, improper, and popular mechanism. It's premise is that the app can go back in time, like you waking up last week with no knowledge of what happened since then. If you can follow that analogy, then imagine your surprise when external things you did last

You can do it without a goroutine as long as the channel has at least one buffer slot so execution passes to the select and uses the data. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group. To unsubscribe from this group and stop receiving emails

Mainly i have bigger requirement: type TestStruct struct { Slice []*TestItem } type TestItem struct { Value1 string Value2 string } so i need to create slice via reflect in TestStruct variable, create variable for TestItem and iterate over TestItem fields and assign to it Value1 and Value2

Thanks. When you're not in a module it returns /dev/null on linux. I don't suppose this is platform independent? On Mon, 2019-12-09 at 06:52 +, Paul Jolly wrote: > go env GOMOD - gives the path to the go.mod in use in module mode, > and is > empty otherwise (i.e. GOPATH mode) > > On Mon, 9
