Simplify deployment by dropping the need to create a webhook ourselves.

Unfortunately this doesn't work because there seems to a recently introduced bug go-gitea/gitea#23139 :(

@kousu kousu force-pushed the auto-webhook branch 3 times, most recently from 13fae9d to 7b00314 Compare February 25, 2023 09:16
Subdirs are simply named by taking the prefix of the input UUID.

This is a common technique to prevent the chance of overflowing filesystem
limits on the number of files allowed in a single directory.

e.g.

Before
 - /srv/gitea/custom/public/90fa9a89-5e50-4bd4-834d-d42655e1ee8e.html
 - http://127.0.0.1:3000/assets/90fa9a89-5e50-4bd4-834d-d42655e1ee8e.html

After:
 - /srv/gitea/custom/public/bids-validator/84/b1/84b10e1c-b188-41e2-a92d-fb6ded9c6889.html
 - http://127.0.0.1:3000/assets/bids-validator/84/b1/84b10e1c-b188-41e2-a92d-fb6ded9c6889.html

The reason for all this is so that we don't installWebhook until we know we own addr. Otherwise we might break an existing webhook.

log.Printf("main: listening on %q", bidsHookUrl)
log.Fatal(server.ListenAndServe())
err = installWebhook()

Suggested change
err = installWebhook()
// to avoid breaking a pre-existing bids-hook only tell Gitea about us once we know we own addr
err = installWebhook()

Actually not: rather this didn't work at all until a month ago; the /admin/hooks API was started two years ago but only got merged recently. The bug is that in those two years things must have shifted around and broken the PR, and they didn't actually test it out.

Before then there would simply be no way to automate this deployment, as far as I can tell. We would have had to rewrite everything to do OAuth, or gone back to using Drone, or just settled for giving manual instructions >.<. And this would be true whether we set up the webhook with ansible or with golang.

Yeah, I had noticed that there was no API for system-level webhooks, and thought we would just give manual instructions for that step. But if/when your upstream PR gets merged and released, we can switch to automatic webhook creation/update.
