Ian, thanks for the explanation and the link ! But I am still unclear how to implement such a concurrent counter in Go - given that we can't find out what thread/cpu is the goroutine executing. Note that in this case there was never the need of pinning a goroutine to a thread or cpu; just that we

[go-nuts] Re: New Context method in http.Request, what can we do with it?

Sure, and that's why gorilla/mux uses context.Context internally. gorilla/sessions (and mux) both existed well before context.Context did, and sessions can't be changed without breaking the public API. On Tuesday, July 12, 2016 at 4:20:59 AM UTC-7, parais...@gmail.com wrote: > > Don't you

[go-nuts] Re: New Context method in http.Request, what can we do with it?

Don't you think it would be better to use context to hold session values rather than using global variables like github.com/gorilla/sessions does ? Le lundi 11 juillet 2016 00:43:05 UTC+2, Matt Silverlock a écrit : > > Use it to pass connection/request-scoped values: that is, values that >

github.com/maruel/panicparse is a good package to do this if you need it. On Tue, 2016-07-12 at 22:26 -0700, Ian Lance Taylor wrote: > On Tue, Jul 12, 2016 at 9:36 PM, Zac Pullar-Strecker wrote: > > Commands like go run, go build and go test amoung others should have > >

Re: [go-nuts] Plurality of package naming

struct and class semantics aren't equivalent but they are similar. Which is why I think the rule "avoid -er" is relevant. If you're struggling to name something then you probably don't know what it is and what it needs to do. I'm not advocating going to the Java extreme of fifty syllable names.

Re: [go-nuts] Initializing a channel as "Closed" so that it doesn't block if a "Thing" hasn't been done yet

I don't understand the problems 100%, but maybe these things can point you in the right direction: - try to see if using a sync.WaitGroup{} can help you. WaitGroups are great to use when you need to keep track of a varying bunch of Go routines. - you can send channels over channels, to wait for

Re: [go-nuts] exec.Cmd: if the child forks Wait may hang forever

If your forked process still has stdin / stdout open then I would say this is expected. You could confirm this by adding the following to the python script. import sys ... if pid == 0: sys.stdin.close() sys.stdout.close() On 13/07/2016 21:50, noxiouz wrote: Good day! I faced a corner
