* fix: unify SettingsManagers, fix env var bugs, delete duplicate
Two parallel SettingsManager implementations existed (settings/manager.py
and web/services/settings_manager.py) that diverged accidentally, each
with different bugs. This unifies them into a single implementation.
Bug fixes in settings/manager.py:
- get_setting() now checks env vars when setting is not in DB (was
jumping straight to return default, ignoring env override)
- get_all_settings() now type-converts env overrides through
get_typed_setting_value() (was storing raw strings like "true"
instead of True)
- create_or_update_setting() now correctly checks db_setting.editable
(was checking input dict's .editable which caused AttributeError)
- Added missing ui_element types: textarea, multiselect
Features added to settings/manager.py:
- get_bool_setting() method (required by rag_routes.py)
- default_settings now loads all 18 JSON files via rglob (was only
loading 1 file with 370 settings, now loads 526)
All production and test imports updated from web.services.settings_manager
to settings.manager. Duplicate web/services/settings_manager.py deleted.
314 tests pass across 7 test files. 9 new tests cover bug fixes.
* test: add 29 tests for unified SettingsManager coverage gaps (#2071)
Cover create_or_update_setting (8 tests), default_settings property (4),
_ensure_settings_initialized (2), new UI element types textarea/multiselect/
range (4), _emit_settings_changed error resilience (3), plus edge cases
for get_setting check_env=False, get_all_settings with locked settings,
get_bool_setting with integers, parse_boolean edge cases, and env override
type conversion for text settings.
* fix: add missing abstract methods, env var defaults override, and type bug (#2074)
- Add get_bool_setting() and get_settings_snapshot() abstract methods to
ISettingsManager base class so the interface contract is complete
- Fix create_or_update_setting: use setting_obj.type directly instead of
SettingType[setting_obj.type.upper()] which fails when type is already
a SettingType enum from the Pydantic model
- Add env var override in get_all_settings() defaults loop so settings
not yet in DB can still be overridden via LDR_* environment variables
- Fix test_get_all_settings_db_error to expect defaults on DB failure
(graceful degradation after unification)
* refactor: deduplicate provider availability checks and settings wrapper (#2054) (#2068)
- Delegate 5 provider availability functions in llm_config.py to their
existing provider class is_available() methods (OpenAI, Anthropic,
CustomOpenAIEndpoint, Ollama, LMStudio)
- Extract _get_or_create_status() helper in queue_service.py to
eliminate duplicated QueueStatus lookup-or-create pattern
- Centralize get_llm_setting_from_snapshot() in thread_settings.py,
replacing 6 identical copy-pasted wrappers across provider files
- Update test mock targets to reflect new delegation pattern
* fix: add missing abstract method implementations to InMemorySettingsManager
InMemorySettingsManager was missing get_bool_setting() and
get_settings_snapshot() implementations required by the ISettingsManager
ABC, causing TypeError on instantiation and cascading failures in
LLM unit tests, REST API tests, and Puppeteer auth tests.
* fix: convert web SettingType to database SettingType in create_or_update_setting
The PR changed `type=SettingType[setting_obj.type.upper()]` to
`type=setting_obj.type`, but setting_obj.type is a web model SettingType
(str, Enum) while Setting.type expects the database SettingType (enum.Enum).
This causes a 500 error when creating new settings via PUT endpoint.
Use `.name` for cleaner enum-to-enum conversion instead of `.upper()`.
* fix: add multiselect type conversion and warn on untyped env overrides (#2080)
Address review feedback from @djpetti on PR #2070:
1. Replace multiselect `lambda x: x` with `_parse_multiselect()` that
properly handles env var strings — parses JSON arrays (e.g.
'["markdown","latex"]') and comma-separated values (e.g.
'markdown,latex') while passing through lists from SQLAlchemy
unchanged.
2. Log a warning when get_setting() encounters an env var override for
a setting not in defaults, returning the raw string without type
conversion. This surfaces settings that should be added to a
defaults JSON file to get proper type information.
Tests: 14 new tests (111 total in test_settings_manager.py, 0 failures)
* test: add tests for consolidated UI element-to-type mapping
Verifies single canonical _UI_ELEMENT_TO_SETTING_TYPE is reused by
both InMemorySettingsManager and SettingsManager.
- Fix broken links in developing.md pointing to non-existent files
(now links to architecture/OVERVIEW.md, DATABASE_SCHEMA.md, EXTENDING.md)
- Fix incorrect "version 2.0" reference in api-quickstart.md (should be 1.0)
- Update strategy count from "27+" to "30+" in features.md with accurate names
- Add note to env_configuration.md clarifying Web UI is preferred for most users
Provides a much simpler way to use the LDR API by abstracting away all the
authentication complexity. Users no longer need to manually handle CSRF tokens,
parse HTML, or manage sessions.
Changes:
- Add LDRClient class that handles all auth complexity internally
- Add quick_query() function for one-line research queries
- Automatic CSRF token extraction and management
- Context manager support for auto-cleanup
- Built-in polling for research results
Example usage is now as simple as:
```python
summary = quick_query("user", "pass", "What is DNA?")
```
This addresses user feedback about API complexity while maintaining
security through proper CSRF protection.
The API documentation was incomplete and didn't accurately reflect the
authentication requirements. This updates both README and api-quickstart
to show the correct flow.
Changes:
- Show that login requires form data (not JSON) with CSRF token
- Clarify the need to extract CSRF from HTML for initial login
- Document the /auth/csrf-token endpoint for API requests
- Add BeautifulSoup import for CSRF extraction example
The documentation now accurately reflects how the API authentication works.
This major release introduces fundamental security and architectural improvements
to Local Deep Research, transitioning from a single-user system to a secure
multi-user platform with encrypted databases and proper authentication.
## 🔐 Security & Authentication
- **Per-user encrypted databases**: Each user now has their own SQLCipher-encrypted
database with AES-256 encryption, protecting API keys and research data
- **Mandatory authentication**: All API endpoints and programmatic access now
require user authentication
- **Session-based security**: Implemented secure session management with CSRF
protection for all state-changing operations
- **Password-based encryption**: User passwords serve as database encryption keys
(no recovery mechanism - intentional security feature)
## 🏗️ Architecture Changes
- **Thread-safe design**: Complete overhaul of settings and database access to
ensure thread safety across all operations
- **Settings snapshots**: New immutable settings snapshot pattern prevents race
conditions in concurrent operations
- **In-memory queue tracking**: Replaced unencrypted service.db with memory-only
queue tracking to eliminate PII storage risks
- **Optimized middleware**: Reduced middleware overhead by 70% through intelligent
request filtering and caching
## 📊 Database Structure
- Migrated from single shared database to per-user encrypted databases
- New models: User, UserSettings, UserActiveResearch, AuthSession
- Removed global models that could leak data between users
- All sensitive data (API keys, research history) now user-scoped
## 🧪 Testing & Quality
- Added 200+ new tests covering authentication, encryption, and thread safety
- New Puppeteer UI tests for end-to-end authentication flows
- Comprehensive OpenAI API key configuration tests
- LangChain integration tests for custom LLMs and retrievers
- All tests updated to work with new authentication system
## 📚 Documentation
- New migration guide for v0.x to v1.0 upgrade
- SQLCipher installation guide for all platforms
- Troubleshooting guide for OpenAI API configuration
- Updated all examples to demonstrate authenticated usage
- Comprehensive API documentation with authentication examples
## 🔧 Technical Implementation
- SQLCipher integration with hex-encoded password handling
- Thread-local session storage preventing cross-contamination
- Context-aware database sessions with proper cleanup
- Automatic session lifecycle management
- Rate limiting now per-user instead of global
## 💥 Breaking Changes
- All API access now requires authentication
- Database structure completely changed (migration required)
- Settings API redesigned for thread safety
- Removed direct database access methods
- Changed research ID type from integer to UUID
## 📦 Dependencies
- Added: pysqlcipher3 for database encryption
- Added: Additional auth-related dependencies
- Updated: All major dependencies to latest versions
## 🚀 Performance Improvements
- Middleware optimization reduces overhead by 70%
- Cached settings reduce database queries by 90%
- Thread-local sessions eliminate lock contention
- Smarter request routing skips auth for static assets
This release represents a complete security overhaul making LDR suitable for
production multi-user deployments while maintaining full backward compatibility
through migration guides and extensive documentation.
