Harry Maclean ef6f0e5b30 Ruby: Add Improper Memoization query
This query finds cases where a method memoizes its result but fails to
include one or more of its parameters in the memoization key (or doesn't
use memoization keys at all). This can lead to the method returning
incorrect results when subsequently called with different arguments.

Ruby analysis support for CodeQL

This directory contains the extractor, CodeQL libraries, and queries that power Ruby support in LGTM and the other CodeQL products that GitHub makes available to its customers worldwide.

It contains two major components:

  1. static analysis libraries and queries written in CodeQL that can be used to analyze such a database to find coding mistakes or security vulnerabilities.
  2. an extractor, written in Rust, that parses Ruby source code and converts it into a database that can be queried using CodeQL. See Developer information for information on building the extractor (you do not need to do this if you are only developing queries).
