Rust-based stats server on fly.io

[alsuren]

working towards #164

To test what I have done so far (forwarding from vercel to fly.io and logging query params):

• accept invite to cargo-quickinstall on fly.io (or send me your email address and I'll add you)
• go to https://fly.io/apps/cargo-quickinstall-stats-server/monitoring
• run cargo quickinstall --force cargo-quickinstall and see what gets printed in the fly.io logs above

I have made a start on a public dashboard at https://alsuren.grafana.net/public-dashboards/12d4ec3edf2548a1850a813e00592b53 . I think I might make a public cargo-bins org with a shared login or something, so we can play about with it more freely.

TODO:

• make the existing stats server proxy http requests onto another stats server that we can all mess about with (or fan out and give everyone their own "staging" server?)
  • probably urlencode things, like /record-install?crate=$crate&version=$version&arch=$arch&client=$client
• (copy-pasta from from switch to hosted influxdb for stats #164):
  • (optional) make the existing stats server proxy http requests onto another stats server that we can all mess about with (or fan out and give everyone their own "staging" server?)
  • write stats to influxdb using the http api
    • read the docs on influxdb https://docs.influxdata.com/influxdb/cloud-iox/get-started/
    • design schema
      • each install request is an integer count of 1 inserted into a "counts" table, with tags for arch, version, package, client etc.
• add people to the org
• dump things into influx
• make get-stats.sh do a thing
• deploy on merge to main
• think about branch deploys?
• ...

placeholder to think about ijagberg/influx#4 at some point. This might involve forking their repo temporarily and deploying from the fork

[alsuren]

oh you know what? it might be a problem with how the js server is encoding the url params?

(still not looked into it properly though)

[alsuren]

Fixed in ijagberg/influx#5 . Depending on my fork for now.

For some reason my vscode is no longer giving any hints for anything in this folder unless I explicitly open only this folder in its own instance. I'm sure it worked before, and for other projects, but I can't remember what I did last time.

Probably I will merge this as is, but if this causes problems for anyone else then tell me and I'll try to address it properly.

Roughly following https://fly.io/docs/launch/continuous-deployment-with-github-actions/ but using an environment to hold the secret, so you can only access the fly secret if you can push to main.

This was tested on a previous commit.
