# Index verify

# Index Integrity Verification Command

## Overview

The `index verify` command performs a comprehensive integrity check of the Spacedrive index for any given path. It compares the actual filesystem state with what's stored in the database and reports any discrepancies.

## Usage

```bash theme={null}
# Basic usage - verify a location
sd-cli index verify /path/to/check

# Verify with content hash checking (slower but more thorough)
sd-cli index verify /path/to/check --verify-content

# Verify without detailed output (just summary)
sd-cli index verify /path/to/check --detailed=false

# Future: Auto-fix issues (not yet implemented)
sd-cli index verify /path/to/check --auto-fix
```

## How It Works

The command performs three main steps:

### 1. Ephemeral Indexing

Runs a fresh, in-memory index scan of the filesystem path to capture the current state:

* Discovers all files and directories
* Extracts metadata (size, modified time, inode)
* Optionally generates content hashes (with `--verify-content`)

### 2. Database Query

Queries the Spacedrive database for all indexed entries under the given path:

* Uses closure table for efficient descendant lookup
* Resolves full paths for all entries
* Extracts stored metadata

### 3. Comparison & Reporting

Compares the two datasets and categorizes differences:

| Issue Type             | Description                                            |
| ---------------------- | ------------------------------------------------------ |
| **Missing from Index** | Files exist on filesystem but not in database          |
| **Stale in Index**     | Files exist in database but not on filesystem          |
| **Metadata Mismatch**  | Files exist in both but with incorrect size/time/inode |
| **Hierarchy Error**    | Files have incorrect parent relationships              |

## When to Use

### Debugging Index Issues

If you suspect the index is out of sync with the filesystem:

```bash theme={null}
sd-cli index verify ~/Documents
```

### After Manual File Operations

If you've manually modified files outside Spacedrive:

```bash theme={null}
# You edited files manually
sd-cli index verify /path/that/changed
```

### Performance Testing

To verify the watcher is working correctly:

```bash theme={null}
# Make changes, then verify
touch /test/newfile.txt
sleep 1
sd-cli index verify /test
```

### Pre-Sync Validation

Before syncing a library to ensure data integrity:

```bash theme={null}
sd-cli index verify /  # Verify entire library
```

## Exit Codes

| Code | Meaning                              |
| ---- | ------------------------------------ |
| 0    | Index is valid (no issues found)     |
| 1    | Index has diverged (issues found)    |
| 2    | Verification failed (error occurred) |

## Use in Scripts

```bash theme={null}
#!/bin/bash
# Automated integrity check

if sd-cli index verify /data/important --detailed=false; then
    echo "Index is valid"
else
    echo "Index has issues - running rescan"
    sd-cli location rescan <location-id>
fi
```

## Performance Characteristics

| Path Size     | Typical Duration | Memory Usage |
| ------------- | ---------------- | ------------ |
| 100 files     | \<1 second       | \~10 MB      |
| 1,000 files   | 1-3 seconds      | \~50 MB      |
| 10,000 files  | 10-30 seconds    | \~200 MB     |
| 100,000 files | 1-5 minutes      | \~1 GB       |

With `--verify-content`:

* Add 50-200% time overhead (depends on file sizes)
* Requires reading file contents for hashing

## Common Use Cases

### 1. Verify Location After Import

```bash theme={null}
sd-cli location add ~/Photos --name "Photos"
# Wait for indexing to complete
sd-cli index verify ~/Photos
```

### 2. Debug Watcher Issues

```bash theme={null}
# Monitor filesystem
watch -n 5 'sd-cli index verify /watched/path --detailed=false'
```

### 3. Find Orphaned Entries

```bash theme={null}
# Check for stale entries
sd-cli index verify / | grep "Stale in index"
```

### 4. Validate After Bulk Operations

```bash theme={null}
# After moving many files
mv ~/old-location/* ~/new-location/
sd-cli index verify ~/new-location
```

## Troubleshooting

### "Path does not exist"

* Ensure the path is correct and accessible
* Check permissions

### "No entries found in database"

* Path might not be part of a managed location
* Run `sd-cli location list` to see indexed locations

### High number of "Missing from Index"

* Location watcher might be disabled
* Files were added manually without indexing
* Run `sd-cli location rescan <location-id>` to fix

### High number of "Stale in Index"

* Files were deleted manually
* Database not updated
* Consider running cleanup

## API Access

The verification can also be triggered programmatically:

```rust theme={null}
use sd_core::ops::indexing::verify::{IndexVerifyAction, IndexVerifyInput};

let input = IndexVerifyInput::new(PathBuf::from("/path/to/verify"));
let result = IndexVerifyAction::from_input(input)?
    .execute(library, context)
    .await?;

if !result.is_valid {
    println!("Found {} issues", result.report.total_issues());
}
```

## Future Enhancements

* `--auto-fix`: Automatically repair issues (add missing, remove stale)
* `--watch`: Continuously verify and report drift
* `--json`: Machine-readable output for automation
* `--compare-with <snapshot>`: Compare current state with previous snapshot
* `--export-snapshot`: Save current state for future comparison
