Comprehensive Update to Email Functionality (0.11.1-RC2)

Type

Enhancement, Documentation, Other

This update introduces a significant overhaul to the email functionality within OneTimeSecret, alongside various configuration enhancements and code quality improvements. Key changes include:

• Introduction of a global configuration file (pr_agent.toml) for the Codium PR Agent, specifying model preferences, git provider, secret provider, and detailed configurations for PR review, description, questions, code suggestions, documentation addition, changelog updates, analysis, testing, checks, and GitHub integration settings.
• Refactoring of the email sending functionality in lib/onetime/email.rb to support both SendGrid and SMTP emailers. This includes the creation of a BaseEmailer class from which SendGridEmailer and SMTPEmailer inherit, encapsulating the email sending logic and setup process. The SendGridEmailer class now includes detailed logging of the email sending process and error handling. The SMTPEmailer class is introduced with SMTP configuration and detailed logging of email delivery details.
• Addition of a basic SMTP checker script (bin/smtp_test.rb) to test SMTP configuration using environment variables defined in the .env file.
• Updates to the .env.example file to include new environment variables for SMTP testing and Redis configuration.
• Minor adjustments in lib/onetime.rb and lib/onetime/logic.rb to align with the refactored email functionality.
• Inclusion of new dependencies in the Gemfile, such as attic, and updates to existing gem versions.
• Enhancement of the .rubocop.yml configuration to enable new cops and specific checks for gemspec attributes and development dependencies.

These changes aim to improve the flexibility, reliability, and maintainability of email functionality within OneTimeSecret, as well as to enhance the overall code quality and configuration management.

pr_agent.toml:

Enhancement Added global configuration for Codium PR Agent (1-191)

Introduced a new global configuration file for the Codium PR Agent, specifying various settings for model, git provider, secret provider, PR reviewer, description, questions, code suggestions, documentation, changelog updates, analysis, testing, checks, and GitHub integration.

bin/smtp_test.rb:

Enhancement Added SMTP configuration test script (1-55)

Questions to better understand the PR:

1. Does the refactoring of the email sending functionality in onetime.rb and email.rb introduce any breaking changes or affect existing functionality?

2. The new smtp_test.rb script:
   a) Only sends a test email
   b) Loads environment variables and sends an email using those configs
   c) Sends an email and logs the delivery status and any errors

3. What was the motivation behind adding support for both SendGrid and SMTP email delivery? Are there plans to deprecate or remove SendGrid in the future?

4. Can you provide more context on the purpose and usage of the new Codium PR Agent configuration file (pr_agent.toml)?

Please respond to the questions above in the following format:

1. The changes to email sending is the main focus of this PR. It resolves an issue I introduced last year that messed up the plain SMTP emailer SMTP Mail sender is dead #257.
2. Exactly yeah. It helped debug mailing credentials so we included it in case it's helpful for anyone else.
3. See (1). We intended to support both with the changes last year, so these updates are a bit like back to the future.
