[RambokDev]

Summary by CodeRabbit

• New Features

  • Added support for MongoDB standard and SRV connection formats.
  • Credentials are safely encoded when constructing MongoDB connection URLs.
  • MongoDB database configuration can omit the port; SRV connections are recognized automatically.
  • Dry-run restore commands now use the same connection settings as regular operations.

• Bug Fixes

  • Improved MongoDB connection error messages for SRV-based connections.
  • Added coverage for authenticated, unauthenticated, SRV, and database-free connection scenarios.

📝 Walkthrough

Walkthrough

The change adds shared MongoDB URI construction for standard and SRV connections. It supports encoded credentials, optional database paths, optional MongoDB ports, restore integration, and SRV-aware ping errors. The development EDGE_KEY value also changes.

Changes

MongoDB URI support

Layer / File(s)	Summary
Optional MongoDB port configuration src/services/config.rs	MongoDB ports are optional and default to 0, which enables SRV configuration.
Shared MongoDB URI builder Cargo.toml, src/domain/mongodb/connection.rs	build_mongo_uri selects standard or SRV schemes, encodes credentials, adds authentication settings, and optionally includes the database path. Unit tests cover these URI forms.
Restore and ping integration src/domain/mongodb/restore.rs, src/domain/mongodb/ping.rs	Dry-run restores use the shared URI builder. Ping errors format SRV targets without a port.

Development environment configuration

Layer / File(s)	Summary
Development EDGE_KEY update docker-compose.yml	The Rust application service uses a different encoded agent and master-key configuration.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to d8351

The change commits a credential-bearing EDGE_KEY value in docker-compose.yml; because base64 does not protect the key, it could enable unauthorized access. Remove it from source control and rotate the exposed key before merging.
