If P1236 ( https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p12... ) is really what it says ("alternative wording") then I don't believe that's true. Certainly P0907R3

Not true, as the post explains.

There is no major upcoming Go change related to this post. This is just a much longer version of https://research.swtch.com/plmm#ub that I drafted years ago and finally cleaned up enough to post.

It's not true that Go can't add new keywords. Now that we have Go modules, all Go code is now explicitly annotated with the version of Go it was written against. We can add a new keyword in a later version of Go as long as the com

If you turn off the GC then no memory is collected. In general this is not something people actually do. The only time I've ever even seen it mentioned is in an old blog post by ESR, and between him and me, at least one of us didn&#x27

The benchmarks in the blog post are believable but the profile is not. The benchmarks do roughly the same amount of cgo work; all the extra work in the finalizer benchmark is setting up the finalizer, specifically 'runtime.addspecial&#

As designed, the system allows an opt-out _either_ by setting GOTELEMETRY=off in your environment or by running 'go env -w GOTELEMETRY=off' which writes a config file. (Specifically the one reported by 'go env GOENV'.) I

You can also echo GOTELEMETRY=off >> $(go env GOENV)

Right. My hope would be that language tooling offering library developers visibility into compile-time information about library usage would reduce their desire to insert run-time collection instead.

I am concerned about run-time telemetry in libraries as well. It might make sense for language ecosystems to offer more data about library usage gathered at build time eventually, as a different system than the one I'm posting about to

The only option is to have a proxy sit in the middle between the uploader and the server. You mentioned Tor but it doesn't have to be Tor, just some proxy most users would trust not to collude with the server and that doesn't itse

My point is about (1) the broader ecosystem of tools that may need to interoperate and have easy access to "SHA256 the whole file" and (2) the fact that not everything is a tar file that the Nix tools can process. So yes, that&#x2

You're not wrong, but you're also not being realistic. Nix is not the only system that takes this approach. The Go modules "directory hash" is roughly equivalent, although we defined it in terms of somewhat more standard

Thanks for the quick rollback. I want to encourage you to think about locking in the current archive details, at least for archives that have already been served. Verifying that downloaded archives have the expected checksum is a critical b

Opting out of background refreshes would mean that fetching a module version that (1) no one else had fetched in a few days and (2) does not use a recognized open-source license might not be in the cache, which would make 'go get&#x27

This isn't true. Sourcehut reported a bug, and since the bug is somewhat involved to fix entirely, we asked what the impact of the bug is to them and offered to make a custom change for the site in the interim. The impact matters: the

The Go team has been making progress toward a complete fix to this problem. Go 1.19 added "go mod download -reuse", which lets it be told about the previous download result including the Git commit refs involved and their hashes.

That code was in turn a loose port of the dial function from Plan 9 from User Space, where I added TCP_NODELAY to new connections by default in 2004 [1], with the unhelpful commit message "various tweaks". If I had known this code

Apologies if the comment sounded like I was trying to provoke. My point was that there is a line, and different languages draw the line in different places. It's true that ints _can_ be made more library-like, but it's also true t

Do types like 'int' and built-in operators like integer division smell bad too?

What a sad world it would be if Git were the end of the story, if no one ever built a more compelling version control system. :-)

This was done as a joke, but not in response to the Go! issue. If you have the original Mercurial repo from the time of the release, you will see it there from the start. I wrote a longer post about this at https://research.swtch

Exactly. In this case, the package manager should use the version of colors that svgo asked for, not the one that appeared on the internet 5 minutes ago.

As far as blessing certain licenses, I believe that we currently recognize all the OSI and SPDX licenses and display documentation for code with any license that permits commercial use. The full list is at https://pkg.go.dev&#x2F
