Add recursive directory scanning to discover SKILL.md files in nested
directories. When a SKILL.md is found, treat sibling directories as
functional folders rather than separate skills.
The switch function was missing two important features after the SQLite
migration:
1. Backfill mechanism: Before switching providers, read the current live
config and save it back to the current provider. This preserves any
manual edits users made to the live config file.
2. Gemini security flags: When switching to a Gemini provider, set the
appropriate security.auth.selectedType:
- PackyCode providers: "gemini-api-key"
- Google OAuth providers: "oauth-personal"
Also update tests to:
- Use the new unified MCP structure (mcp.servers) instead of the legacy
per-app structure (mcp.codex.servers)
- Expect backfill behavior (was incorrectly marked as "no backfill")
- Remove assertions for provider-specific file deletion (v3.7.0+ uses
SSOT, no longer creates per-provider config files)
This merge brings the SQLite migration system from feat/sqlite-migration branch:
## New Features
- Schema version control with SCHEMA_VERSION constant
- Automatic migration of missing columns for providers table
- Dry-run validation mode for schema compatibility checks
- JSON→SQLite migration feature gate (CC_SWITCH_ENABLE_JSON_DB_MIGRATION)
- Settings reload mechanism after imports
## Test Updates
- Updated tests to use SQLite database instead of config.json
- Removed obsolete import_config_from_path tests (replaced by db.import_sql)
- Fixed MCP tests to use unified McpServer structure (v3.7.0+)
- Updated provider switch tests to reflect no-backfill behavior
- Adjusted error type matching for new error variants
This commit refactors all tests to work with the new database-based
architecture, replacing the previous JSON config approach.
Key changes:
- Add Database export to lib.rs for test access
- Create test helper functions in support.rs:
- create_test_state(): Creates empty test state with fresh DB
- create_test_state_with_config(): Migrates JSON config to DB
- Fix environment isolation in provider_service tests:
- provider_service_switch_missing_provider_returns_error
- provider_service_switch_codex_missing_auth_returns_error
- Replace ignored export tests with working alternatives:
- export_sql_writes_to_target_path (tests Database::export_sql)
- export_sql_returns_error_for_invalid_path (tests error handling)
- Update error type matching to align with current implementation
All tests now:
- Use isolated test environments (test_mutex + reset_test_fs)
- Access data via Database API instead of RwLock<MultiAppConfig>
- Work with SQLite persistence layer
- Pass without environment pollution or race conditions
Fixes test compilation errors after database migration.
Replace Mutex with RwLock for AppState.config to enable concurrent reads,
improving performance for tray menu building and query operations that
previously blocked each other unnecessarily.
Key changes:
- Migrate AppState.config from Mutex<MultiAppConfig> to RwLock<MultiAppConfig>
- Distinguish read-only operations (read()) from mutations (write()) across
all command handlers and service layers
- Offload blocking file I/O in import/export commands to spawn_blocking threads,
minimizing lock hold time and preventing main thread blocking
- Extract load_config_for_import() to separate I/O logic from state updates
- Update all integration tests to use RwLock semantics
Performance impact:
- Concurrent reads: Multiple threads can now query config simultaneously
(tray menu, provider list, MCP config)
- Reduced contention: Write locks only acquired during actual mutations
- Non-blocking I/O: Config import/export no longer freezes UI thread
All existing tests pass with new locking semantics.
- Extract internal functions in commands/mcp.rs and commands/provider.rs
to enable unit testing without Tauri context
- Add test hooks: set_mcp_enabled_test_hook, import_mcp_from_claude_test_hook,
import_mcp_from_codex_test_hook, import_default_config_test_hook
- Migrate error types from String to AppError for precise error matching in tests
- Extend ProviderService with delete() method to unify Codex/Claude cleanup logic
- Add comprehensive test coverage:
- tests/mcp_commands.rs: command-level tests for MCP operations
- tests/provider_service.rs: service-level tests for switch/delete operations
- Run cargo fmt to fix formatting issues (EOF newlines)
- Update BACKEND_REFACTOR_PLAN.md to mark phase 3 complete
Architecture improvements:
- Extract ProviderService with switch/backfill/write methods
- Reduce command layer from 160 to 13 lines via delegation
- Separate business logic (services) from state management (commands)
- Introduce precise error handling with structured validation
Refactoring details:
- Split Codex/Claude switching into symmetric private methods
- Add multi-layer validation for Codex auth field (existence + type)
- Extract import_config_from_path for command and test reuse
- Expose export_config_to_file and ProviderService in public API
Test coverage:
- Add 10+ integration tests for Claude/Codex switching flows
- Cover import/export success and failure scenarios (JSON parse, missing file)
- Verify state consistency on error paths (current remains unchanged)
- Test snapshot backfill for both old and new providers after switching
Key improvements:
- Extract switch_provider_internal() returning AppError for better testability
- Fix backup mtime inheritance: use read+write instead of fs::copy to ensure latest backup survives cleanup
- Add 15+ integration tests covering provider commands, atomic writes, and rollback scenarios
- Expose write_codex_live_atomic, AppState, and test hooks in public API
- Extract tests/support.rs with isolated HOME and mutex utilities
Test coverage:
- Provider switching with live config backfill and MCP sync
- Codex atomic write success and failure rollback
- Backup retention policy with proper mtime ordering
- Negative cases: missing auth field, invalid provider ID
