Summary of Changes

Hello @dennisg, 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 focuses on a significant dependency upgrade, moving the project's MongoDB Go driver to its second major version, v2.4.2. This update is crucial for maintaining compatibility, leveraging the latest features, and ensuring the application benefits from performance improvements and bug fixes in the new driver. The upgrade involved a series of targeted code modifications across multiple files to adapt to the new API surface, ensuring seamless integration with the updated driver.

Highlights

  • MongoDB Driver Upgrade: The go.mongodb.org/mongo-driver dependency has been upgraded from v1.17.4 to v2.4.2 in go.mod.
  • API Adaptations for v2: Code has been updated to align with breaking API changes in MongoDB driver v2, including modifications to import paths (e.g., go.mongodb.org/mongo-driver/v2), changes in function signatures to use *options.FindOptionsBuilder and *options.FindOneOptionsBuilder, and adjustments to mongo.Connect and various options builder methods (e.g., options.UpdateMany(), options.DeleteOne()).
  • Dependency Cleanup: The indirect dependency github.com/montanaflynn/stats has been removed from go.mod.
Ignored Files
  • Ignored by pattern: go.sum (1)

Code Review

This pull request successfully updates the MongoDB driver to v2, which involves necessary changes to import paths and function signatures. Most of the changes correctly reflect the new API. However, there are a few places where the options.FindOptionsBuilder and options.FindOneOptionsBuilder are passed directly to methods that expect *options.FindOptions and *options.FindOneOptions respectively, which will lead to compilation errors. Additionally, a mongo.Connect call in the integration tests needs to be updated to match the new v2 signature. Please address these issues to ensure full compatibility with the new driver version.
