goreleaser VS futures-rs

I also got my eyes on GoReleaser, which I will use in my (Go) projects.

With "xq", I went even further and automated the release process using GoReleaser. To publish a new release, the only thing I need is to create and push the Git tag. The corresponding GitHub Action will trigger a release process, and GoReleaser prepares the binaries and changelog based on declared conventions. The result has a high level of predictability, and no manual work is required.

Things I can't live without in a new Go project in no particular order:

- https://github.com/golangci/golangci-lint - meta-linter

- https://goreleaser.com - automate release workflows

- https://magefile.org - build tool that can version your tools

- https://github.com/ory/dockertest/v3 - run containers for e2e testing

- https://github.com/ecordell/optgen - generate functional options

- https://golang.org/x/tools/cmd/stringer - generate String()

- https://mvdan.cc/gofumpt - stricter gofmt

- https://github.com/stretchr/testify - test assertion library

- https://github.com/rs/zerolog - logging

- https://github.com/spf13/cobra - CLI framework

FWIW, I just lifted all the tools we use for https://github.com/authzed/spicedb

We've also written some custom linters that might be useful for other folks: https://github.com/authzed/spicedb/tree/main/tools/analyzers

Goreleaser is nice. https://goreleaser.com/

I use goreleaser for packaging my binaries. I'm not currently doing RPM, but it does a lot of services and if you don't hunker down on a single solution, it might help with keeping your releases up to date/in sync.

There's some packaging issues, for example, we've always wanted to publish deb/rpm packages, but never got around to adding it to either promu or completely switching our build tooling over to GoReleaser.

So this is actually better than true fairness (true fairness would lead to deadlock if a sender is forgotten). It is a pity that the there does not seem to be resources that document this design. There is this old thread where Carl provides some background, but I found it personally a bit hard to follow.

Is this still true after it switched to using FuturesOrdered?

Done.

You can use Streams, which are the async version of Iterators; They aren't stable yet, so you'll have to use a crate such as futures.

futures

For traits, like AsyncRead and AsyncWrite, go with the futures crate.

Here is the PR: https://github.com/rust-lang/futures-rs/pull/2551

Yield = wake the `waker_ref`. Avoiding the yield would be clone().wake().

That said, "poll immediately" isn't actually a thing nor was it ever a thing except in incorrect implementations.

Rust lacks an implementation of ReactiveX. futures/futures-signals seems to be the the ecosystem equivalent but I'm sure there'd be a lot of interest in an actual implementation.

The opposite problem exists as well. Many types are actually unwind safe, but do not get the autotrait. In that case authors would have to manually declare them UnwindSafe. Because this is rarely done, having an API with a trait bound T: UnwindSafe is rarely viable in terms of ergonomics. It now obliges client code to wrap all calls to your API in AssertUnwindSafe which, if they use types from third party libraries, obliges them to assert this is fine. example

Also, we plan to give users more control in the future. See https://github.com/rust-lang/futures-rs/issues/2207, https://github.com/rust-lang/futures-rs/issues/2295, etc. for this
