[go-nuts] Re: Small number change will affect benchmark results

More specifically, the last parameter (needzero) of mallocgc is not passed down to c.nextFree, which causes the memclrNoHeapPointers function is called twice in makeslicecopy if the slice size <= 32768. On Wednesday, August 18, 2021 at 11:06:53 PM UTC-4 tapi...@gmail.com wrote: > Spent some

[go-nuts] Re: Small number change will affect benchmark results

Spent some time on investigating this problem. It is confirmed that, when N == 16384, the memclrNoHeapPointers function is called twice in the Insert2 function. That means the "make+copy` optimization introduced in Go 1.15 will perform worse than the normal route under such situation. On

Re: [go-nuts] Leading dash invalid in test filename inside module

Awesome, thanks. At a previous company, we used to take months/years to upgrade to a new Go version, so it's nice that you guys are eating your own dog food so quickly. :-) For now, I've removed the leading-dash test file and released a new patch version. When I reinstate it I may end up putting

Re: [go-nuts] Leading dash invalid in test filename inside module

You're exactly right, the proxy is still in the process of migrating to Go 1.17. It should be done in the next day or two, at which point it should be able to fetch this version. In the mean time, you can work around it by setting GOPRIVATE= github.com/benhoyt/goawk

[go-nuts] Leading dash invalid in test filename inside module

(I wasn't quite sure whether golang-nuts or golang-dev was the best place for this -- sending to golang-nuts for now.) I just released a new version of GoAWK (v1.8.0) using Go version 1.17, and then tested installing it using "go install". However, go install complains with the following: $ go

[go-nuts] Re: how golang stores variables in the computer’s memory?

It will also help you look knowledgeable if you refer to the language as Go, never `golang`. The name of the language is just 'Go'. In my experience the term golang should only be used when you need to clarify for a search engine. I don't usually bother correct people on this issue, but given

[go-nuts] proxying plaintext requests over HTTP Connect

I have an HTTP Proxy configured that only accepts HTTP CONNECT requests to proxy requests to upstream servers, with some upstream servers using HTTPS and some using HTTP. However, the behavior in https://golang.org/src/net/http/transport.go around line 1638 makes it so that HTTP CONNECT
