My solution to the Level 4 of Stripe CTF 3.

This is a completely distributed solution implemented using goraft (although by the end I had hardcoded some stuff like [column count](https://github.com/gaganpreet/stripe-ctf3-level4/blob/master/minesql/sql.go#L60-65) and [strings for compression](https://github.com/gaganpreet/stripe-ctf3-level4/blob/master/util/util.go#L56-85))

# SQLCluster

SQLCluster makes your SQLite highly-available.

## Getting started

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.

## Building and running

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.

## Protocol

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 `curl`s you can run locally).

## Supported platforms

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.
