Implement Solution A (complete deferred submission) for custom endpoint
management, replacing the dual-mode system with unified local staging.
Changes:
- Remove immediate backend saves from EndpointSpeedTest
* handleAddEndpoint: local state update only
* handleRemoveEndpoint: local state update only
* handleSelect: remove lastUsed timestamp update
- Add explicit clear detection in ProviderForm
* Distinguish "user cleared endpoints" from "user didn't modify"
* Pass empty object {} as clear signal vs null for no-change
- Fix mergeProviderMeta to handle three distinct cases:
* null/undefined: don't modify endpoints (no meta sent)
* empty object {}: explicitly clear endpoints (send empty meta)
* with data: add/update endpoints (overwrite)
Fixed Critical Bug:
When users deleted all custom endpoints, changes were not saved because:
- draftCustomEndpoints=[] resulted in customEndpointsToSave=null
- mergeProviderMeta(meta, null) returned undefined
- Backend interpreted missing meta as "don't modify", preserving old values
Solution:
Detect when user had endpoints and cleared them (hadEndpoints && length===0),
then pass empty object to mergeProviderMeta as explicit clear signal.
Architecture Improvements:
- Transaction atomicity: all fields submitted together on form save
- UX consistency: add/edit modes behave identically
- Cancel button: true rollback with no immediate saves
- Code simplification: removed ~40 lines of immediate save error handling
Testing:
- TypeScript type check: passed
- Rust backend tests: 10/10 passed
- Build: successful
Add optional accessToken and userId fields to usage query scripts,
enabling queries to authenticated endpoints like /api/user/self.
Changes:
- Add accessToken and userId fields to UsageScript type (frontend & backend)
- Extend script engine to support {{accessToken}} and {{userId}} placeholders
- Update NewAPI preset template to use /api/user/self endpoint
- Add UI inputs for access token and user ID in UsageScriptModal
- Pass new parameters through service layer to script executor
This allows users to query usage data from endpoints that require
login credentials, providing more accurate balance information for
services like NewAPI/OneAPI platforms.
Add compatibility for providers that use ANTHROPIC_API_KEY instead of
ANTHROPIC_AUTH_TOKEN, enabling support for AiHubMix and similar services.
Changes:
- Backend: Add fallback to ANTHROPIC_API_KEY in credential extraction
- migration.rs: Support API_KEY during config migration
- services/provider.rs: Extract credentials from either field
- Frontend: Smart API key field detection and management
- getApiKeyFromConfig: Read from either field (AUTH_TOKEN priority)
- setApiKeyInConfig: Write to existing field, preserve user choice
- hasApiKeyField: Detect presence of either field
- Add AiHubMix provider preset with dual endpoint candidates
- Define apiKeyField metadata for provider presets (documentation)
Technical Details:
- Uses or_else() for zero-cost field fallback in Rust
- Runtime field detection ensures correct field name preservation
- Maintains backward compatibility with existing configurations
- Priority: ANTHROPIC_AUTH_TOKEN > ANTHROPIC_API_KEY
Upgrade Claude model configuration from dual-key to quad-key system for
better model tier differentiation.
**Breaking Changes:**
- Replace `ANTHROPIC_SMALL_FAST_MODEL` with three granular keys:
- `ANTHROPIC_DEFAULT_HAIKU_MODEL`
- `ANTHROPIC_DEFAULT_SONNET_MODEL`
- `ANTHROPIC_DEFAULT_OPUS_MODEL`
**Backend (Rust):**
- Add `normalize_claude_models_in_value()` for automatic migration
- Implement fallback chain: `DEFAULT_* || SMALL_FAST || MODEL`
- Auto-cleanup: remove legacy `SMALL_FAST` key after normalization
- Apply normalization across 6 critical paths:
- Add/update provider
- Read from live config
- Write to live config
- Refresh config snapshot
**Frontend (React):**
- Expand UI from 2 to 4 model input fields
- Implement smart fallback in `useModelState` hook
- Update `useKimiModelSelector` for Kimi model picker
- Add i18n keys for Haiku/Sonnet/Opus labels (zh/en)
**Configuration:**
- Update all 7 provider presets to new format
- DeepSeek/Qwen/Moonshot: use same model for all tiers
- Zhipu: preserve tier differentiation (glm-4.5-air for Haiku)
**Backward Compatibility:**
- Old configs auto-upgrade on first read/write
- Fallback chain ensures graceful degradation
- No manual migration required
Closes #[issue-number]
This commit implements a three-layer fix to restore the "Sync to other side"
feature when adding or editing MCP servers across Claude and Codex.
Root Cause Analysis:
1. Frontend issue: New MCP entries had their `enabled` field deleted
2. Backend issue: Default value was `false` when `enabled` was missing
3. Core issue: MCP entries were never copied to the other app's servers
Changes:
Frontend (McpFormModal.tsx):
- Set `enabled=true` by default for new MCP entries
- Preserve existing `enabled` state when editing
Backend (services/mcp.rs):
- Change default value from `unwrap_or(false)` to `unwrap_or(true)`
- Implement cross-app MCP replication when `sync_other_side=true`
- Clone MCP entry to other app's servers before syncing to live files
Impact:
- "Sync to Codex" checkbox now correctly adds MCP to both Claude and Codex
- "Sync to Claude" checkbox now correctly adds MCP to both Codex and Claude
- Both config.json and live files (~/.claude.json, ~/.codex/config.toml) are updated
- Fixes regression introduced during project restructure
Tested:
- TypeScript type checking passed
- Rust clippy linting passed
- Manual testing: MCP sync works bidirectionally
This commit continues the backend refactoring initiative by extracting
configuration management and API speedtest logic into dedicated service
layers, completing phase 4 of the architectural improvement plan.
## Changes
### New Service Layers
- **ConfigService** (`services/config.rs`): Consolidates all config
import/export, backup management, and live sync operations
- `create_backup()`: Creates timestamped backups with auto-cleanup
- `export_config_to_path()`: Exports config to specified path
- `load_config_for_import()`: Loads and validates imported config
- `import_config_from_path()`: Full import with state update
- `sync_current_providers_to_live()`: Syncs current providers to live files
- Private helpers for Claude/Codex-specific sync logic
- **SpeedtestService** (`services/speedtest.rs`): Encapsulates endpoint
latency testing with proper validation and error handling
- `test_endpoints()`: Tests multiple URLs concurrently
- URL validation now unified in service layer
- Includes 3 unit tests for edge cases (empty list, invalid URLs, timeout clamping)
### Command Layer Refactoring
- Move all import/export commands to `commands/import_export.rs`
- Commands become thin wrappers: parse params → call service → return JSON
- Maintain `spawn_blocking` for I/O operations (phase 5 optimization)
- Lock acquisition happens after I/O completes (minimize contention)
### File Organization
- Delete: `import_export.rs`, `speedtest.rs` (root-level modules)
- Create: `commands/import_export.rs`, `services/config.rs`, `services/speedtest.rs`
- Update: Module declarations in `lib.rs`, `commands/mod.rs`, `services/mod.rs`
### Test Updates
- Update 20 integration tests in `import_export_sync.rs` to use `ConfigService` APIs
- All existing test cases pass without modification to test logic
- Add 3 new unit tests for `SpeedtestService`:
- `sanitize_timeout_clamps_values`: Boundary value testing
- `test_endpoints_handles_empty_list`: Empty input handling
- `test_endpoints_reports_invalid_url`: Invalid URL error reporting
## Benefits
1. **Improved Testability**: Service methods are `pub fn`, easily callable
from tests without Tauri runtime
2. **Better Separation of Concerns**: Business logic isolated from
command/transport layer
3. **Enhanced Maintainability**: Related operations grouped in cohesive
service structs
4. **Consistent Error Handling**: Services return `Result<T, AppError>`,
commands convert to `Result<T, String>`
5. **Performance**: I/O operations run in `spawn_blocking`, locks released
before file operations
## Testing
- ✅ All 43 tests passing (7 unit + 36 integration)
- ✅ `cargo fmt --check` passes
- ✅ `cargo clippy -- -D warnings` passes (zero warnings)
## Documentation
Updated `BACKEND_REFACTOR_PLAN.md` to reflect completion of config and
speedtest service extraction, marking phase 4 substantially complete.

Extract all MCP business logic from command layer into `services/mcp.rs`,
implementing snapshot isolation pattern to optimize lock granularity after
RwLock migration in Phase 5.
## Key Changes
### Service Layer (`services/mcp.rs`)
- Add `McpService` with 7 methods: `get_servers`, `upsert_server`,
`delete_server`, `set_enabled`, `sync_enabled`, `import_from_claude`,
`import_from_codex`
- Implement snapshot isolation: acquire write lock only for in-memory
modifications, clone config snapshot, release lock, then perform file I/O
with snapshot
- Use conditional cloning: only clone config when sync is actually needed
(e.g., when `enabled` flag is true or `sync_other_side` is requested)
### Command Layer (`commands/mcp.rs`)
- Reduce to thin wrappers: parse parameters and delegate to `McpService`
- Remove all `*_internal` and `*_test_hook` functions (-94 lines)
- Each command now 5-10 lines (parameter parsing + service call + error mapping)
### Core Logic Refactoring (`mcp.rs`)
- Rename `set_enabled_and_sync_for` → `set_enabled_flag_for`
- Remove file sync logic from low-level function, move sync responsibility
to service layer for better separation of concerns
### Test Adaptation (`tests/mcp_commands.rs`)
- Replace test hooks with direct `McpService` calls
- All 5 MCP integration tests pass
### Additional Fixes
- Add `Default` impl for `AppState` (clippy suggestion)
- Remove unnecessary auto-deref in `commands/provider.rs` and `lib.rs`
- Update Phase 4/5 progress in `BACKEND_REFACTOR_PLAN.md`
## Performance Impact
**Before**: Write lock held during file I/O (~10ms), blocking all readers
**After**: Write lock held only for memory ops (~100μs), file I/O lock-free
Estimated throughput improvement: ~2x in high-concurrency read scenarios
## Testing
- ✅ All tests pass: 5 MCP commands + 7 provider service tests
- ✅ Zero clippy warnings with `-D warnings`
- ✅ No behavioral changes, maintains original save semantics
Part of Phase 4 (Service Layer Abstraction) of backend refactoring roadmap.
- 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
