use playpen to implement a sandbox for running code on the rust website

[thestinger]

I made a simple sandbox for the bot on #rust, and I plan on making a web frontend for it. The service as a whole could run in a VM since it's still vulnerable to a kernel exploit in one of the whitelisted system calls.

Since rustc uses at least 70MiB of memory and up to 128-150MiB for reasonably small examples, we'll need to limit the concurrency based on the chosen resource limit for the sandbox and the memory available.

This would be a nice way to let people try to language before going through the relatively long compile.

TODO list

• ec2 instance - playtest.rust-lang.org
• styling the same as the main rust website
• DNS record for play.rust-lang.org (or some similar name)
• ability to submit code to the server and have it compiled/run
• rustdoc integration -- links on all code examples to submit and compile. Note that this should submit all the commented out portions of the example as well (which rustdoc hides by default).
• fork rust-playpen to the rust-lang organization

(bug triage) Still a great idea; not a blocker.

TheHydroImpulse/rust-website seems to implement that.

@adridu59 Yeah, I've been implementing @thestinger's playpen for the website.

We've got an ec2 instance running now at ec2-54-215-67-200.us-west-1.compute.amazonaws.com. There's still a number of tasks to take care of before turning this on officially, and I'd love to see them get done! I've added a number of TODO items to the issue description.

This is now (temporarily) available at http://playtest.rust-lang.org.

Sweet!

A CNAME has been setup, this is now available at http://play.rust-lang.org/.

I'm going to close this issue in favor of more specific ones like #14575. Thanks @thestinger, awesome work!
