SRAS -- An Asset Server for OpenSimulator

NOTICE

On 12-18-2014, coyled declared the SRAS system abandonware. Recently as of Ruby 2.0 people have had issues installing, as several dependencies require Ruby 2.0 or greater but some of the commands used had been depreciated as of 2.0 (it's noted that File.exists was depreciated at 2.1 but we get the error with anything 2.0 or above). I've decided to take up this project & tinker with it in my spare time since this system is still used by so many grids out there. Please note this should be considered an ALPHA build, but seems to be stable.

Features

• Asset de-duplication
• Compressed asset storage on disk
• Ability to disable serving of specific assets without deleting
• Mesh MIME type support added (thx Hack13)

Install

The packages of Ruby shipping with Ubuntu don't include built-in zlib support. I prefer using RVM [ http://rvm.beginrescueend.com/ ] anyway.

Built & tested with Ruby v1.9.2.

Install via:

$ gem install sras

then copy the following text into /etc/sras/sras.conf or ~/.srasrc and edit as appropriate: ::

sras:
    production:
        default_asset_dir: /srv/sras
        port: 8003
        log_file: /var/log/sras.log
        pid_file: /tmp/sras.pid

mysql:
    production:
        adapter: mysql
        host: localhost
        username: sras
        password: sras
        database: sras

Running

Then just:

$ sras start

to start a single instance. In a production environment you would likely want to run several instances behind a reverse proxy like Nginx.

To see additional options:

$ sras --help

Testing

To test asset creation:

$ curl -d @test/test.asset -X POST -w '%{http_code}\n' \
    http://yourserver.example.com:8003/assets/

You should get a 200 HTTP response, have an entry in your assets table, and have a file contain the asset data on disk.

To test retrieval of that asset:

$ curl -X GET -w '%{http_code}\n' \
    http://yourserver.example.com:8003/assets/0193663d-44e4-4e6e-9a1c-8dd2febc5fc5/data
