Summary of Changes

Hello @jaredwray, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces SASL (Simple Authentication and Security Layer) support by integrating a new Memcached service configured for SASL authentication. This setup provides a dedicated environment for testing and developing features that require secure, authenticated access to Memcached.

Highlights

  • New Memcached Service with SASL: A new memcached-sasl service has been added to docker-compose.yml, specifically configured to run a Memcached instance with SASL authentication enabled for testing purposes.
  • SASL-enabled Dockerfile: A new Dockerfile (test/sasl/Dockerfile) was introduced to build a Memcached image that includes SASL utilities (sasl2-bin), a plain authentication mechanism, and a predefined test user (testuser with password testpass).
  • Memcached Configuration: The SASL-enabled Memcached container is configured to use /etc/sasldb2 for password storage and runs with the -S flag to enforce SASL authentication.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request adds SASL support for memcached by introducing a new Docker service for testing. My review focuses on the new Dockerfile and includes several recommendations to improve security and adhere to Docker best practices. Key suggestions include avoiding hardcoded credentials, running the container with a non-privileged user, pinning the base image to a specific version for reproducibility, and optimizing the Dockerfile structure.

P1 Badge Serialize binary requests to avoid response misrouting

binaryRequest adds a fresh data listener for every call without any shared queue or response routing. If two binary* operations run concurrently on the same node (e.g., Promise.all([binaryGet(...), binarySet(...)])), both listeners will receive the same first response, resolve with the wrong data, and the later response will be dropped because both listeners remove themselves. This makes concurrent SASL/binary usage return incorrect results or hang. Consider reusing a single binary response parser with a queue (like the text command queue) or otherwise ensuring requests are strictly serialized.
