Enhance indexing system with new scopes and persistence modes

This update introduces a refined indexing system that supports multiple indexing scopes (current and recursive) and persistence options (persistent and ephemeral). The CLI commands have been updated to reflect these changes, allowing for quick scans and external path browsing without database writes. Documentation has been revised to include detailed descriptions of the new features, use cases, and command comparisons, ensuring clarity for users. Additionally, the codebase has been refactored to accommodate these enhancements, improving overall functionality and performance.

### Indexing
### Enhanced Indexing
The new indexing system supports different scopes and persistence modes:
```bash
# Start indexing with default settings (content mode)
spacedrive index ~/Desktop
# Quick scan of current directory only (no subdirectories)
spacedrive index quick-scan /path/to/directory --scope current
# Index with specific mode
spacedrive index ~/Videos --mode shallow # Metadata only
spacedrive index ~/Photos --mode deep # Full analysis
# Quick scan with ephemeral mode (no database writes)
spacedrive index quick-scan /path/to/directory --scope current --ephemeral
# Index and watch progress
spacedrive index ~/Documents --watch
# Browse external paths without adding to managed locations
spacedrive index browse /media/external-drive --scope current
spacedrive index browse /network/drive --scope recursive --content
# Index managed locations with specific scope
spacedrive index location /managed/location --scope current --mode shallow
spacedrive index location <location-uuid> --scope recursive --mode deep
# Legacy full location indexing (backward compatibility)
spacedrive scan /path/to/directory --mode content --watch
```
**Index Scopes:**
- `current`: Index only the specified directory (single level)
- `recursive`: Index the directory and all subdirectories
**Index Modes:**
- `shallow`: Metadata only (fastest)
- `content`: Metadata + content hashing (moderate)
- `deep`: Full analysis including media metadata (slowest)
**Use Cases:**
- **UI Navigation**: `quick-scan --scope current` for instant directory viewing
- **External Browsing**: `browse --ephemeral` for exploring non-managed paths
- **Location Updates**: `location --scope current` to refresh specific directories

## Indexing Scopes and Persistence
### Index Scopes
The indexing system supports two different scopes for different use cases:
#### Current Scope
- **Description**: Index only the specified directory (single level)
- **Use Cases**: UI navigation, quick directory browsing, instant feedback
- **Performance**: <500ms for typical directories
- **Implementation**: Direct directory read without recursion
```rust
let config = IndexerJobConfig::ui_navigation(location_id, path);
// Results in single-level scan optimized for UI responsiveness
```
#### Recursive Scope
- **Description**: Index the directory and all subdirectories
- **Use Cases**: Full location indexing, comprehensive file discovery
- **Performance**: Depends on directory tree size
- **Implementation**: Traditional recursive tree traversal
```rust
let config = IndexerJobConfig::new(location_id, path, mode);
// Default recursive behavior for complete coverage
```
### Persistence Modes
#### Persistent Mode
- **Storage**: Database (SQLite/PostgreSQL)
- **Use Cases**: Managed locations, permanent indexing
- **Features**: Full change detection, resumability, sync support
- **Lifecycle**: Permanent until explicitly removed
```rust
let config = IndexerJobConfig::new(location_id, path, mode);
config.persistence = IndexPersistence::Persistent;
```
#### Ephemeral Mode
- **Storage**: Memory (EphemeralIndex)
- **Use Cases**: External path browsing, temporary exploration
- **Features**: No database writes, session-based caching
- **Lifecycle**: Exists only during application session
```rust
let config = IndexerJobConfig::ephemeral_browse(path, scope);
// Results stored in memory, automatic cleanup
```
### Enhanced Configuration
The new `IndexerJobConfig` provides fine-grained control:
```rust
pub struct IndexerJobConfig {
pub location_id: Option<Uuid>, // None for ephemeral
pub path: SdPath, // Path to index
pub mode: IndexMode, // Shallow/Content/Deep
pub scope: IndexScope, // Current/Recursive
pub persistence: IndexPersistence, // Persistent/Ephemeral
pub max_depth: Option<u32>, // Depth limiting
}
```
### Use Case Examples
#### UI Directory Navigation
```rust
// Fast current directory scan for UI
let config = IndexerJobConfig::ui_navigation(location_id, path);
// - Scope: Current (single level)
// - Mode: Shallow (metadata only)
// - Persistence: Persistent
// - Target: <500ms response time
```
#### External Path Browsing
```rust
// Browse USB drive without adding to library
let config = IndexerJobConfig::ephemeral_browse(usb_path, IndexScope::Current);
// - Scope: Current or Recursive
// - Mode: Shallow (configurable)
// - Persistence: Ephemeral
// - Target: Exploration without database pollution
```
#### Background Location Indexing
```rust
// Traditional full location scan
let config = IndexerJobConfig::new(location_id, path, IndexMode::Deep);
// - Scope: Recursive (default)
// - Mode: Deep (full analysis)
// - Persistence: Persistent
// - Target: Complete coverage
```
### Ephemeral Index Structure
The `EphemeralIndex` provides temporary storage:
```rust
pub struct EphemeralIndex {
pub entries: HashMap<PathBuf, EntryMetadata>,
pub content_identities: HashMap<String, EphemeralContentIdentity>,
pub created_at: Instant,
pub last_accessed: Instant,
pub root_path: PathBuf,
pub stats: IndexerStats,
}
```
Features:
- **LRU Behavior**: Automatic cleanup based on access time
- **Memory Efficient**: Lightweight metadata storage
- **Session Scoped**: Cleared on application restart
- **Fast Access**: Direct HashMap lookups
## Database Schema
### Core Tables
@@ -202,49 +325,85 @@ Change types detected:
- Reduces database round trips
- Improves memory efficiency
### Scope Optimizations
- **Current Scope**: Direct directory read without recursion (<500ms target)
- **Recursive Scope**: Efficient tree traversal with depth control
- **Ephemeral Mode**: Memory-only storage for external path browsing
- **Early Termination**: Configurable max_depth limiting
### Caching
- Path prefix cache
- Parent entry ID cache
- Change detection cache
- Entry ID cache for parent lookups
- Change detection cache for inode/timestamp comparisons
- Ephemeral index LRU cache for session-based storage
- Content identity cache for deduplication
### Parallelization
- Concurrent CAS ID generation
- Parallel file type detection
- Async I/O operations
- Batch processing across multiple threads
### Database Optimizations
- Bulk inserts
- Prepared statements
- Strategic indexing
- Bulk inserts with transaction batching
- Prepared statements for repeated operations
- Strategic indexing on location_id and relative_path
- Persistence abstraction for database vs memory storage
## Usage Examples
### Starting an Indexing Job
### Enhanced Indexing Jobs
```rust
use sd_core_new::operations::indexing::{IndexerJob, IndexMode};
use sd_core_new::operations::indexing::{
IndexerJob, IndexerJobConfig, IndexMode, IndexScope, IndexPersistence
};
// Create indexer job
let job = IndexerJob::new(
location_id,
location_path,
IndexMode::Deep, // Shallow, Content, or Deep
);
// Dispatch through job manager
// UI Navigation - Fast current directory scan
let config = IndexerJobConfig::ui_navigation(location_id, path);
let job = IndexerJob::new(config);
let handle = library.jobs().dispatch(job).await?;
// Monitor progress
while let Some(progress) = handle.progress().await {
println!("Progress: {:?}", progress);
}
// Ephemeral Browsing - External path exploration
let config = IndexerJobConfig::ephemeral_browse(external_path, IndexScope::Current);
let job = IndexerJob::new(config);
let handle = library.jobs().dispatch(job).await?;
// Traditional Location Indexing - Full recursive scan
let config = IndexerJobConfig::new(location_id, path, IndexMode::Deep);
let job = IndexerJob::new(config);
let handle = library.jobs().dispatch(job).await?;
// Custom Configuration - Fine-grained control
let mut config = IndexerJobConfig::new(location_id, path, IndexMode::Content);
config.scope = IndexScope::Current;
config.max_depth = Some(2);
let job = IndexerJob::new(config);
```
### Legacy API (Backward Compatibility)
```rust
// Old API still works for simple cases
let job = IndexerJob::from_location(location_id, path, IndexMode::Deep);
let job = IndexerJob::shallow(location_id, path);
let job = IndexerJob::with_content(location_id, path);
```
### Indexing Modes
- **Shallow**: Metadata only (fastest)
- **Content**: Includes CAS ID generation
- **Deep**: Full analysis including thumbnails (future)
- **Shallow**: Metadata only (fastest, <500ms for UI)
- **Content**: Includes CAS ID generation (moderate performance)
- **Deep**: Full analysis including thumbnails (comprehensive)
### Indexing Scopes
- **Current**: Single directory level (UI navigation, quick browsing)
- **Recursive**: Full directory tree (complete location indexing)
### Persistence Options
- **Persistent**: Database storage (managed locations, permanent data)
- **Ephemeral**: Memory storage (external browsing, temporary exploration)
