[go-nuts] Re: Does sync.(*Pool).Put slow to cause latency spikes sometimes?

Yes, there is only pointers in sync.Pool. I think the sync.Pool only slow during GCing is a normal behavior. If the sync.Pool's method slow with out GCing is a runtime issue. I donot agree: sync.Pool just amortizes the cost of creating garbage The sync.Pool is reusing object and reducing crea

[go-nuts] Re: Does sync.(*Pool).Put slow to cause latency spikes sometimes?

sync.Pool just amortizes the cost of creating garbage, does not eliminiate it... You have to pay for your garbage somewhere! Are you sure you put only pointers into yout Pool? 2018. augusztus 13., hétfő 6:57:48 UTC+2 időpontban nea...@gmail.com a következőt írta: > > Hi, > > My services show so

Re: [go-nuts] Re: Is there a way to clear a map similar to slice = slice[:0]?

What does it mean to clear a map? Even if Go admitted that a map was a specific form of hash table with certain chaining/bucket choices, what would an empty one be that is different than a new one? I can think of answers to this but if you say what behavior you want to optimize by clearing and reus

Hi, I'm developing my first Go program that is supposed to upload files into a Google Cloud Storage bucket from a Raspberry Pi 1. It uses the https://github.com/blackjack/webcam library to grab a picture from an USB camera. I can compile the program on the Raspberry Pi itself with Go 1.7.4 tha

[go-nuts] Is there a way to clear a map similar to slice = slice[:0]?

With slices, you can do slice = slice[:0] to remove the values from the slice, but keep the backing slice with the same capacity (although the elements aren't marked for GC I believe, if that's a concern). With maps, is there a similar pattern? I've tried: for key := range m { delete(m, key)

Hi Benny, > if I understand correctly, the plan with versioned packages and modules is to > deprecate the vendor folder and GOPATH some time after Go 1.11. That is true of GOPATH; the case is less clear-cut with vendor. See also the discussion about vendor as part of: https://github.com/golang/
