Trackless Sea

"If you want to build a ship, don’t drum up the men to gather wood, divide the work, and give orders. Instead, teach them to yearn for the vast and endless sea." - apocryphal, often credited to Antoine de Saint-Exupéry

Trackless Sea is meant to be a playground built on the Demiurge HTML game engine. See Demiurge and Demiurge-Createjs for more details about the gritty software chunks that make Trackless Sea work.

Start the Server and Your First Security Certificate

$ scripts/start_server

Setting up a security certificate for local use can be quite painful. Unfortunately, I don't want to default to an insecure configuration and then have people deploy that in production.

The first time you run start_server it'll make you a new certificate and put it where Trackless will use it. But Chrome is still likely to complain loudly about using a self-signed certificate.

You have two choices here.

First, you can configure Chrome to allow insecure certs for localhost - it's a good choice for web developers and may help with projects other than Trackless as well! Here's a StackOverflow question discussing the problem, including details about the second solution below: "https://stackoverflow.com/questions/7580508/getting-chrome-to-accept-self-signed-localhost-certificate". Quoted from that question, your solution one is to put "chrome://flags/#allow-insecure-localhost" in the top bar in Chrome, then hit "Enable" on the setting that shows up in yellow highlight text.

Or second, you can instead configure your host to trust the certificate you're using. Keychain Access is the app that does that -- you can find it under the Utils folder under Applications by default. You can't modify System Root certificates any more, so you'll need to drag trackless_server.crt (or a copy) into the window. Then "Get Info" on it (it'll show up as localhost.ssl), pull open the "Trust" tab and mark it as "Trust Always".

Can I Skip the Security Certificate Stuff?

It is possible to set things up with really cruddy security for local development to avoid having to set up a local self-signed certificate, even though I've made the start_server script already create one for you. You will have to either set up Chrome to allow self-signed local certificates or make your host trust your certificate. And maybe that's a smaller problem for you than leaking everybody's password and causing a huge, legally-actionable data breach because you normally run insecure and you forgot to change that on the server for just this one deploy, or your deploy was done by somebody who didn't know that step.

Awesome.

In that case, all you need to do is change index.html and the start_server script to the wrong, bad configuration. I won't tell you how, even though it's very easy. Later, I may add security checks to index.html and/or the libraries as well, even though those will be slightly more annoying for you to disable. Why? Because I want a horrific security breach to be slightly harder than no horrific security breach. And setting up certificates is currently a really awful pain. Also, if setting up certs gets easier I want my stuff to default in the right direction then too.

Is there a time deploying without a security certificate is warranted? Sure. If you set a particular application up with no password and no personally-identifying info for a particular application then you don't much care if people see the random packets being sent. It's basically all public anyway. In that case and ONLY in that case, feel free to disable the security.

That's not how Trackless Sea works, though. If you disable the security and then try to get people to use a password they remember (usually their real and only one) and then leak that, you're a terrible person and you deserve whatever horrible thing happens to you.
