q3k 97b5cd7b58 go: re-do the entire thing This is a mega-change, but attempting to split this up further is probably not worth the effort. Summary: 1. Bump up bazel, rules_go, and others. 2. Switch to new go target naming (bye bye go_default_library) 3. Move go deps to go.mod/go.sum, use make gazelle generate from that 4. Bump up Python deps a bit And also whatever was required to actually get things to work - loads of small useless changes. Tested to work on NixOS and Ubuntu 20.04: $ bazel build //... $ bazel test //...

README.md

Statusz-like page for Go

This module adds a /debug/status handler to net/http that displays useful information for debug purposes in production.

Basic Usage

For the basic status page, just include the module.

import (
    _ "code.hackerspace.pl/hscloud/go/statusz"
)

func main() {
    http.ListenAndServe("127.0.0.1:6000", nil)
}

Adding sections

To add a section to the status page, call AddStatusSection like so:

import (
    "code.hackerspace.pl/hscloud/go/statusz"
)


func main() {
    statusz.AddStatusPart("Worker Status", function(ctx context.Context) {
        return fmt.Sprintf("%d workers alive", workerCount)
    })
    http.ListenAndServe("127.0.0.1:6000", nil)
}

For custom section templates, call AddStatusPart, which accepts a http/template fragment that will be rendered on the result of the part render function.
