Re: [go-nuts] [Macos/Apple M1] HTTP client requests to ".local" domain adds 5 seconds overhead

Thanks! I added the IPv6 loopback address to all my host names in /etc/hosts (i.e. "::1 mydomain.local") and it now works as expected. I guess Go's DNS resolver was timing out at the first attempt, that's why I consistently had that 5 second delay. torsdag 1 april 2021 kl. 07:40:10 UTC+2 skrev

Re: [go-nuts] Transferring host's go-mod-download cache into docker container

There are a couple ways I know of that you can do this. You can vendor or copy as you mention. Another approach is to create a "build" image that contains relevant credentials and a few `go env -w` directives to set up your build environment, which you build separately and derive other project

Re: [go-nuts] Can I import a package from a git submodule?

It's really annoying to deal with when you have private repositories, but try to simply `import RepoB/bar` from ModuleA, and don't bother with the submodule stuff. Module SHAs will replicate submodule functionality in a way that's more compatible with the language. On Wed, Mar 31, 2021 at 1:46 PM

Re: [go-nuts] Can I import a package from a git submodule?

AIUI, if you nest modules (that is, a subdirectory of a module containing a directory with its own `go.mod`), the "inner" module is not considered part of the "outer" module. In particular, it would also not be included in the module zip (which is the primary way modules are distributed - *not* as

Consider this layout: - Repo A contains module foo - Repo B contains module bar (of course ;) - Repo B is added as submodule to repo A at /baz I was expecting that I can import "foo/baz/bar" in repo A, but that leads to error ("no required module provides package..."). Shouldn't t

I've set up a development environment on my MacBook Pro M1 (running Big Sur 11.2.3, Go 1.16.2) with a number of small Go/.Net HTTP APIs that are communication with each other. To replicate our production infrastructure I've set up /etc/hosts with ".local" domains pointing to 127.0.0.1. An nginx

[go-nuts] Finding error type for `errors.As` and `errors.Is`

Hi everyone, I often encounter deep error chains where errors are wrapped across several Go packages and that makes it often hard to find a usable error type to use with `errors.As` or `errors.Is`. Could it make sense to add an `errors.Chain` function to Go that returns a slice with tuples of

Re: [go-nuts] Help with tcpserver

I think that in principle you are correct to perform your reads inside a goroutine, to allow them to be received asynchronously. If Read() blocks, it's not a problem unless you want to shut down the connection from the server side, and you can do that by setting a read timeout which will unbloc
