**Summary:** The provided code changes cover several security-related improvements to the Brakeman security scanner for Ruby on Rails applications, as well as updates to the test suite for a Rails 4 application. The key security-focused changes include: 1. Expansion of the Brakeman check to cover additional ActiveRecord query methods, such as `find_by` and `find_by!`, to improve the detection of unscoped queries that can lead to security vulnerabilities. 2. Enhancements to the Brakeman check to handle optional `belongs_to` associations, which can also result in unscoped queries. 3. Improvements to the handling of potentially missing records in the `UsersController` by using the `find_by!` method, which raises an exception instead of returning a `nil` value, leading to more robust error handling. 4. Additions to the Rails 4 test suite, including a new test case for unscoped calls to the `Email#find_by!` method and continued testing for various security vulnerabilities, such as SQL injection, cross-site scripting (XSS), and command injection. These changes demonstrate a strong focus on improving the security of Ruby on Rails applications by enhancing the capabilities of the Brakeman security scanner and strengthening the test coverage for security-related issues. **Files Changed:** 1. `lib/brakeman/checks/check_unscoped_find.rb`: This file is part of the Brakeman security scanner, and the changes expand the check for unscoped ActiveRecord queries to include `find_by` and `find_by!` methods, in addition to `find` and `find_by_id`. The changes also handle optional `belongs_to` associations, further improving the scanner's ability to detect potential security vulnerabilities. 2. `test/apps/rails4/app/controllers/users_controller.rb`: The changes in this file update the `email_find_by` method to use the `find_by!` method instead of `find_by`, which can lead to more robust error handling and reduce the risk of SQL injection vulnerabilities. 3. `test/tests/rails4.rb`: This file contains the test suite for the Rails 4 application. The changes include the addition of a new test case for unscoped calls to the `Email#find_by!` method, as well as updates to the expected number of "generic" warnings. The existing test cases for various security vulnerabilities, such as SQL injection, XSS, and command injection, demonstrate a strong focus on application security.
