The goal of this refactoring is to eliminate the global configuration singleton (`config.Cfg`) and replace it with explicit dependency injection of a `Config` struct.
This commit includes the following partial changes:
- The `Config` struct in `internal/platform/config/config.go` has been updated with all necessary fields.
- Several platform packages (`db`, `cache`, `auth`, `http`, `jobs/sync`) have been modified to accept the `*config.Config` struct.
- The API server entry point (`cmd/api/main.go`) has been updated to load and provide the configuration.
- A new worker entry point (`cmd/worker/main.go`) has been created to house the background job runner, as per the architecture defined in `refactor.md`.
NOTE: The build is currently broken as this refactoring is incomplete. This commit is for saving progress as requested.
- Fixes a potential panic in the background job queue by changing `log.Fatalf` to `log.Printf`, allowing for more graceful error handling.
- Implements all `panic("not implemented")` methods in the mock repositories for `Like`, `Work`, and `User`, enabling more robust testing.
- Consolidates duplicated `WorkAnalytics` and `TranslationAnalytics` structs into a central `internal/domain/analytics` package to reduce code duplication and improve maintainability.
- Corrects build errors that arose during testing, including an unused import and an incorrect struct field name in a mock repository.
This commit introduces the `MergeWork` command, a new feature to merge two `Work` entities, their associations, and their statistics. The entire operation is performed atomically within a database transaction to ensure data integrity.
Key changes include:
- A new `MergeWork` method in `internal/app/work/commands.go`.
- An `Add` method on the `WorkStats` entity for combining statistics.
- A new `GetWithAssociationsInTx` method on the `WorkRepository` to fetch entities within a transaction.
- A comprehensive integration test using an in-memory SQLite database to validate the merge logic.
This commit also consolidates all scattered TODOs and build issues from `TODO.md` and `BUILD_ISSUES.md` into a single, actionable `TASKS.md` file. The legacy documentation files have been removed to create a single source of truth for pending work.
This commit introduces a comprehensive set of foundational improvements to make the API more robust, secure, and observable.
The following features have been implemented:
- **Observability Stack:** A new `internal/observability` package has been added, providing structured logging with `zerolog`, Prometheus metrics, and OpenTelemetry tracing. This stack is fully integrated into the application's request pipeline.
- **Centralized Authorization:** A new `internal/app/authz` service has been created to centralize authorization logic. This service is now used by the `user`, `work`, and `comment` services to protect all Create, Update, and Delete operations.
- **Standardized Input Validation:** The previous ad-hoc validation has been replaced with a more robust, struct-tag-based system using the `go-playground/validator` library. This has been applied to all GraphQL input models.
- **Structured Error Handling:** A new set of custom error types has been introduced in the `internal/domain` package. A custom `gqlgen` error presenter has been implemented to map these domain errors to structured GraphQL error responses with specific error codes.
- **`updateUser` Endpoint:** The `updateUser` mutation has been fully implemented as a proof of concept for the new patterns, including support for partial updates and comprehensive authorization checks.
- **Test Refactoring:** The test suite has been significantly improved by decoupling mock repositories from the shared `testutil` package, resolving circular dependency issues and making the tests more maintainable.
