Support for net/http Packages at Compile time

[davidmdm]

TinyGo currently does not support net/http/* packages as documented here.

This is unfortunate as use-cases exist where we would want to import packages that depend on net/http/* but do not need to run networking.

For example in the Kubernetes space, we would like to write programs that depend on k8s.io/api, apimachinery and third-party operator types. Unfortunately these packages depend on net/http packages and we cannot compile them using tinygo.

Resulting in errors such as:

../../../../go/pkg/mod/golang.org/x/net@v0.37.0/internal/httpcommon/request.go:11:2: package net/http/httptrace is not in std (/Users/davidmdm/Library/Caches/tinygo/goroot-844030248698ae6eab7078512b4fefd9cf5525da9617ec2f86276fb6aa7030bc/src/net/http/httptrace)

The ask is to implement/stub/mock enough of net/http to allow tinygo to work with the kubernetes ecosystem at least at the type level.
The ask is NOT to implement networking or http.

Related issues:

• wasm file generation error: package net/http/httptrace is not in std #4186
• Missing various net/http packages in std #4598

This would imply that the following program would compile successfully:

package main

import (
	"fmt"

	metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
)

func main() {
	fmt.Println(metav1.ObjectMeta{})
}

@davidmdm You can take a look at this: https://github.com/kubewarden/k8s-objects

@b0ch3nski I am aware of that repo. In some cases it is good enough, but as soon as you want to depend on types found in third party operators you are back to square one.
