When you click Run button on dlang.dzfl.pl, ajax makes POST request to local process.php (can be any scripting language, probably making it js-only could work with some iframes-hacking). Then it requests http://dpaste.dzfl.pl API via POST and it returns JSON with response.

http://dpaste.dzfl.pl service resides on unaffected server, while compiler service resides on 4 (hope to add more mirrors in near future) machines. I've implemented small load balancer in D.

Whole infrastructure is written in D and uses different approaches, containers on linux mirrors and jails on freebsd mirrors.

Each request has limited resources, execution time, IO access etc.

Website itself (http://dpaste.dzfl.pl) is written in PHP, but I am thinking about switching to D in near future (not sure what framework pick up yet, vibe.d, serenity or own implementation).

If you want to know more details, let me know

FYI: Someone somewhere has that up on their demo site. Don't know why it hasn't been activated.

You mean Adam Ruppe's take on executable code snippets?

Yeah, that would be the one. It allows for editing too though.

Oh cool. That's great!

textarea -> JSON -> AJAX -> PHP Script -> ....... -> Load Balancer -> Chroot jail -> D Compiler.


How do you perform interation between php and you load balancer?

Nice! Any links?

Well, to be honest, I was working mainly on http://dpaste.dzfl.pl but I was asked if I wanna integrate http://dlang.org with it, so here it is.

Actually it is:
textarea -> Ajax -> PHP Script -> JSON -> http://dpaste.dzfl.pl -> Load Balancer -> Target Jail -> JSON back to http://dpaste.dzfl.pl -> JSON -> PHP Script -> Your output window :D

Load balancer has list of available mirrors, it randomizes this list and in foreach loop tries to connect to host, if it success it just returns, otherwise it continues until it success. When Chroot Jail, has too many connections OR resources for Compiler infrastructure are out, its just cut outs socket connection, so balancer goes forwards and connects to another one.

Here you can see it in action:
http://dpaste.dzfl.pl/66612383

Copy example, create new paste and click couple of times "Compile".
I have Linux and FreeBSD mirrors so its showes how requests are forwarded

That's crazy shit yeha xD... and php and load balancer do communication via TCP/UNIX socket? some kind of protocol?

What happened to GDC and LDC compiler options?  ;~)

I want to try to release http://dpaste.dzfl.pl beta soon and officially announce service, while
GDC and LDC requires some more work from me (mainly writing scripts for automatic building).

I really would love to see ready binaries for Debian (Linux in overall) and FreeBSD but probably won't happen :p

Not sure why, but I have small problems with building both, GDC and LDC on FreeBSD, both on my server and local vm.

In short words:
So as for now, I removed them from list. But they will be back.
