SQLCluster makes your SQLite highly-available.

To run this level, you'll need a working Go installation. If you don't have one yet, it's quite easy to obtain. Just grab the appropriate installer from:

https://code.google.com/p/go/downloads/list

Then set your GOPATH environment variable:

http://golang.org/doc/code.html#GOPATH

It'll probably be convenient to check this code out into $GOPATH/src/stripe-ctf.com/sqlcluster (that way, go build will know how to compile it without help). However, you can use the provided build.sh regardless of where you happened to check this level out.

Run ./build.sh to build the SQLCluster binary.

As always, you can run test cases via test/harness. This will automatically fetch and compile Octopus, download your test cases, and score your level for you.

Octopus will print out your score, together with how it arrived at said score.

SQCluster communicates with the outside world over HTTP. The public interface is simple:

POST /sql:

input:  A raw SQL body

output: A message with the form "SequenceNumber: $n", followed
        by the output of that SQL command.

Run ./build.sh to build SQLCluster and have it print out some example usage (including curls you can run locally).

SQLCluster has been tested on Mac OSX and Linux. It may work on other platforms, but we make no promises. If it's not working for you, see https://stripe-ctf.com/about#development for advice on getting a development environment similar to our own.
