Boosting Security & Performance: Key Fixes Ready!

by SLV Team 50 views

Hey guys! Ready to dive into some exciting updates? We've got a batch of critical fixes lined up, focused on boosting both security and performance for our project. This is all about making things safer, faster, and smoother for everyone involved. Let's break down what's happening and how it's going to improve things.

📦 Commits Ready to Go

We've got four solid commits on the feature/backoffice branch, all prepped and ready to be pushed to GitHub and merged into main. This is a big step towards enhancing the overall quality and efficiency of the system. Each commit addresses specific issues and contributes to the broader goal of a more robust and responsive application.

Commits Breakdown:

  1. b331558 - fix(rls): resolve empty media articles display after SECURITY INVOKER migration

    This commit tackles a frustrating issue where media articles weren't displaying correctly after a crucial security migration. We've added GRANT SELECT permissions to articles_presse, ensuring that the necessary data is accessible. We've also implemented five RLS (Row-Level Security) policies, setting up a solid foundation for data access control. The policies include public read access and comprehensive CRUD (Create, Read, Update, Delete) capabilities for admins. To keep things clean, we've updated the declarative schema and removed any debug logs that were cluttering things up. This ensures the system runs smoothly and provides the right information at the right time. This is a game-changer for media article display, resolving a major bug that was impacting users.

  2. 8645103 - security(views): fix all views to use SECURITY INVOKER instead of SECURITY DEFINER

    Security is paramount, right? This commit is all about tightening up our security posture. We've converted ten views to use SECURITY INVOKER instead of SECURITY DEFINER. This is a significant improvement because it ensures that views run with the permissions of the user accessing them, not the permissions of the database owner. We've also created an automated test script to verify that these views are behaving as expected. Plus, we've updated seven schema files to reflect these changes. By using SECURITY INVOKER, we're making sure that our system is less vulnerable to potential security breaches, and that user data is protected. This is a crucial step in maintaining the integrity and confidentiality of our data.

  3. a7b4a62 - perf(rls): optimize articles_presse policies using RESTRICTIVE for admin

    Performance is key to a great user experience. This commit focuses on optimizing the RLS policies for articles_presse. We've converted the admin policy to RESTRICTIVE, which means admin users will experience faster query times. This change yields a performance gain of approximately 40% for non-admins. We've also documented the issue related to OR semantics, making sure everyone understands the implications. Faster query times lead to a much more responsive user interface, so this is a win-win for everyone involved. This optimization enhances the overall user experience and contributes to a more efficient system.

  4. e7a8611 - feat(ui): add admin dashboard link to protected page

    Lastly, we're making it easier for admins to navigate the system with a small but useful UI enhancement. We've added a link to the admin dashboard on a protected page. This makes it easier for admins to access their tools and manage the system. It's a small change, but it improves the user experience for admins and streamlines their workflow.

📊 Technical Summary

Let's get down to the technical details, shall we?

  • 3 Critical Issues Resolved: We've successfully tackled three major issues: empty article displays, SECURITY DEFINER views, and performance bottlenecks in RLS policies.
  • 4 Migrations Created: Four new migrations have been created to support these changes, ensuring a smooth transition.
