# CHANGELOG: Message & Metadata Persistence
## v1.0.4 (2026-02-07) - Archive Viewer Feature
### Added
- ✅ **Archive Viewer Page** (`/archive`) - Full-featured message archive browser
- Pagination (50 messages per page, configurable)
- Channel filter dropdown (All + configured channels)
- Time range filter (24h, 7d, 30d, 90d, All time)
- Text search (case-insensitive)
- Filter state persistence (app.storage.user)
- Message cards with same styling as main messages panel
- Clickable messages for route visualization (where available)
- **💬 Reply functionality** - Expandable reply panel per message
- ✅ **MessageArchive.query_messages()** method
- Filter by: time range, channel, text search, sender
- Pagination support (limit, offset)
- Returns tuple: (messages, total_count)
- Sorting: Newest first
- ✅ **UI Integration**
- "📚 View Archive" button in Actions panel
- Opens in new tab
- Back to Dashboard button in archive page
- ✅ **Reply Panel** (NEW!)
- Expandable reply per message (💬 Reply button)
- Pre-filled with @sender mention
- Channel selector
- Send button with success notification
- Auto-close expansion after send
### Changed
- 🔄 `SharedData.get_snapshot()`: Now includes `'archive'` field
- 🔄 `ActionsPanel`: Added archive button and open handler
- 🔄 Both entry points (`__main__.py` and `meshcore_gui.py`): Register `/archive` route
### Features
- **Pagination**: Navigate large archives efficiently
- **Filters**: Time range + channel + text search
- **Persistent State**: Filters remembered across sessions
- **Consistent UI**: Same message styling as dashboard
- **Route Integration**: Click messages to view route (if in recent buffer)
- **Reply from Archive**: Direct reply capability for any archived message
### UI/UX
- **Message Cards**: Expandable reply panel integrated
- **Pre-filled Reply**: Auto-mention sender (@sender)
- **Channel Selection**: Choose reply channel
- **Feedback**: Success notification after sending
- **Smart Collapse**: Reply panel closes after send
### Performance
- Query: ~10ms for 10k messages with filters
- Memory: ~10KB per page (50 messages)
- No impact on main UI (separate page)
### Known Limitations
- Route visualization only works for messages in recent buffer (last 100)
- Archived-only messages show warning notification
- Text search is linear scan (no indexing yet)
- Sender filter exists in API but not in UI yet
### Future Improvements
- Archive-based route visualization (use message_hash)
- Sender filter UI component
- Export to CSV/JSON
- Advanced filters (SNR, hop count)
- Full-text search indexing
---
## v1.0.3 (2026-02-07) - Critical Bugfix: Archive Overwrite Prevention
### Fixed
- 🐛 **CRITICAL**: Fixed bug where archive was overwritten instead of appended on restart
- 🐛 Archive now preserves existing data when read errors occur
- 🐛 Buffer is retained for retry if existing archive cannot be read
### Changed
- 🔄 `_flush_messages()`: Early return on read error instead of overwriting
- 🔄 `_flush_rxlog()`: Early return on read error instead of overwriting
- 🔄 Better error messages for version mismatch and JSON decode errors
### Details
**Problem:** If the existing archive file had a JSON parse error or version mismatch,
the flush operation would proceed with `existing_messages = []`, effectively
overwriting all historical data with only the new buffered messages.
**Solution:** The flush methods now:
1. Try to read existing archive first
2. If read fails (JSON error, version mismatch, IO error), abort the flush
3. Keep buffer intact for next retry
4. Only clear buffer after successful write
**Impact:** No data loss on restart or when archive files have issues.
### Testing
- ✅ Added `test_append_on_restart_not_overwrite()` integration test
- ✅ Verifies data is appended across multiple sessions
- ✅ All existing tests still pass
---
## v1.0.2 (2026-02-07) - RxLog message_hash Enhancement
### Added
- ✅ `message_hash` field added to `RxLogEntry` model
- ✅ RxLog entries now include message_hash for correlation with messages
- ✅ Archive JSON includes message_hash in rxlog entries
### Changed
- 🔄 `events.py`: Restructured `on_rx_log()` to extract message_hash before creating RxLogEntry
- 🔄 `message_archive.py`: Updated rxlog archiving to include message_hash field
- 🔄 Tests updated to verify message_hash persistence
### Benefits
- **Correlation**: Link RX log entries to their corresponding messages
- **Analysis**: Track which packets resulted in messages
- **Debugging**: Better troubleshooting of packet processing
### Example RxLog Entry (Before)
```json
{
"time": "12:34:56",
"timestamp_utc": "2026-02-07T12:34:56Z",
"snr": 8.5,
"rssi": -95.0,
"payload_type": "MSG",
"hops": 2
}
```
### Example RxLog Entry (After)
```json
{
"time": "12:34:56",
"timestamp_utc": "2026-02-07T12:34:56Z",
"snr": 8.5,
"rssi": -95.0,
"payload_type": "MSG",
"hops": 2,
"message_hash": "def456..."
}
```
**Note:** For non-message packets (announcements, broadcasts), `message_hash` will be an empty string.
---
## v1.0.1 (2026-02-07) - Entry Point Fix
### Fixed
- ✅ `meshcore_gui.py` (root entry point) now passes ble_address to SharedData
- ✅ Archive works correctly regardless of how application is started
### Changed
- 🔄 Both entry points (`meshcore_gui.py` and `meshcore_gui/__main__.py`) updated
---
## v1.0.0 (2026-02-07) - Initial Release
### Added
- ✅ MessageArchive class for persistent storage
- ✅ Configurable retention periods (MESSAGE_RETENTION_DAYS, RXLOG_RETENTION_DAYS, CONTACT_RETENTION_DAYS)
- ✅ Automatic daily cleanup of old data
- ✅ Batch writes for performance
- ✅ Thread-safe with separate locks
- ✅ Atomic file writes
- ✅ Contact retention in DeviceCache
- ✅ Archive statistics API
- ✅ Comprehensive tests (20+ unit, 8+ integration)
- ✅ Full documentation
### Storage Locations
- `~/.meshcore-gui/archive/<ADDRESS>_messages.json`
- `~/.meshcore-gui/archive/<ADDRESS>_rxlog.json`
### Requirements Completed
- R1: All incoming messages persistent ✅

# Message & Metadata Persistence
**Version:** 1.0
**Author:** PE1HVH
**Date:** 2026-02-07
## Overview
This feature implements persistent storage for all incoming messages, RX log entries, and contacts with configurable retention periods. The system uses a dual-layer architecture to balance real-time UI performance with comprehensive data retention.
## Architecture
```
┌─────────────────────────────────────┐
│ SharedData (in-memory buffer) │
│ - Last 100 messages (UI) │
│ - Last 50 rx_log (UI) │
│ - Thread-safe via Lock │
└──────────────┬──────────────────────┘
│ (on every add)
▼
┌─────────────────────────────────────┐
│ MessageArchive (persistent) │
│ - All messages (JSON) │
│ - All rx_log (JSON) │
│ - Retention filtering │
│ - Automatic cleanup (daily) │
│ - Separate Lock (no contention) │
└─────────────────────────────────────┘
```
### Design Principles
1. **Separation of Concerns**: SharedData handles real-time UI updates, MessageArchive handles persistence
2. **Thread Safety**: Independent locks prevent contention between UI and archiving
3. **Batch Writes**: Buffered writes reduce disk I/O (flushes every 10 items or 60 seconds)
4. **Configurable Retention**: Automatic cleanup based on configurable periods
5. **Backward Compatibility**: SharedData API unchanged, archive is optional
## Storage Format
### Messages Archive
**Location:** `~/.meshcore-gui/archive/<ADDRESS>_messages.json`
```json
{
"version": 1,
"address": "literal:AA:BB:CC:DD:EE:FF",
"last_updated": "2026-02-07T12:34:56.123456Z",
"messages": [
{
"time": "12:34:56",
"timestamp_utc": "2026-02-07T12:34:56.123456Z",
"sender": "PE1HVH",
"text": "Hello mesh!",
"channel": 0,
"direction": "in",
"snr": 8.5,
"path_len": 2,
"sender_pubkey": "abc123...",
"path_hashes": ["a1", "b2"],
"message_hash": "def456..."
}
]
}
```
### RX Log Archive
**Location:** `~/.meshcore-gui/archive/<ADDRESS>_rxlog.json`
```json
{
"version": 1,
"address": "literal:AA:BB:CC:DD:EE:FF",
"last_updated": "2026-02-07T12:34:56Z",
"entries": [
{
"time": "12:34:56",
"timestamp_utc": "2026-02-07T12:34:56Z",
"snr": 8.5,
"rssi": -95.0,
"payload_type": "MSG",
"hops": 2,
"message_hash": "def456..."
}
]
}
```
**Note:** The `message_hash` field enables correlation between RX log entries and messages. It will be empty for packets that are not messages (e.g., announcements, broadcasts).
## Configuration
Add to `meshcore_gui/config.py`:
```python
# Retention period for archived messages (in days)
MESSAGE_RETENTION_DAYS: int = 30
# Retention period for RX log entries (in days)
RXLOG_RETENTION_DAYS: int = 7
# Retention period for contacts (in days)
CONTACT_RETENTION_DAYS: int = 90
```
## Usage
### Basic Usage
The archive is automatically initialized when SharedData is created with a BLE address:
```python
from meshcore_gui.core.shared_data import SharedData
# With archive (normal use)
shared = SharedData("literal:AA:BB:CC:DD:EE:FF")
# Without archive (backward compatible)
shared = SharedData() # archive will be None
```
### Adding Data
All data added to SharedData is automatically archived:
```python
from meshcore_gui.core.models import Message, RxLogEntry
# Add message (goes to both SharedData and archive)
msg = Message(
time="12:34:56",
sender="PE1HVH",
text="Hello!",
channel=0,
direction="in",
)
shared.add_message(msg)
# Add RX log entry (goes to both SharedData and archive)
entry = RxLogEntry(
time="12:34:56",
snr=8.5,
rssi=-95.0,
payload_type="MSG",
hops=2,
)
shared.add_rx_log(entry)
```
### Getting Statistics
```python
# Get archive statistics
stats = shared.get_archive_stats()
if stats:
print(f"Total messages: {stats['total_messages']}")
print(f"Total RX log: {stats['total_rxlog']}")
print(f"Pending writes: {stats['pending_messages']}")
```
### Manual Flush
Archive writes are normally batched. To force immediate write:
```python
if shared.archive:
shared.archive.flush()
```
### Manual Cleanup
Cleanup runs automatically daily, but can be triggered manually:
```python
if shared.archive:
shared.archive.cleanup_old_data()
```
## Performance Characteristics
### Write Performance
- Batch writes: 10 messages or 60 seconds (whichever comes first)
- Write time: ~10ms for 1000 messages
- Memory overhead: Minimal (only buffer in memory, ~10 messages)
### Startup Performance
- Archive loading: <500ms for 10,000 messages
- Archive is counted, not loaded into memory
- No impact on UI responsiveness
### Storage Size
With default retention (30 days messages, 7 days rxlog):
- Typical message: ~200 bytes JSON
- 100 messages/day → ~6KB/day → ~180KB/month
- Expected archive size: <10MB
## Automatic Cleanup
The BLE worker runs cleanup daily (every 86400 seconds):
1. **Message Cleanup**: Removes messages older than `MESSAGE_RETENTION_DAYS`
2. **RxLog Cleanup**: Removes entries older than `RXLOG_RETENTION_DAYS`
3. **Contact Cleanup**: Removes contacts not seen for `CONTACT_RETENTION_DAYS`
Cleanup is non-blocking and runs in the background worker thread.
## Thread Safety
### Lock Ordering
1. SharedData acquires its lock
2. SharedData calls MessageArchive methods
3. MessageArchive acquires its own lock
This ordering prevents deadlocks.
### Concurrent Access
- SharedData lock: Protects in-memory buffers
- MessageArchive lock: Protects file writes and batch buffers
- Independent locks prevent contention
## Error Handling
### Disk Write Failures
- Atomic writes using temp file + rename
- If write fails: buffer retained for retry
- Logged to debug output
- Application continues normally
### Corrupt Archives
- Version checking on load
- Invalid JSON → skip and start fresh
- Corrupted data → logged, not loaded
### Missing Directory
- Archive directory created automatically
- Parent directories created if needed
## Testing
### Unit Tests
```bash
python -m unittest tests.test_message_archive
```
Tests cover:
- Message and RxLog archiving
- Batch write behavior
- Retention cleanup
- Thread safety
- JSON serialization
### Integration Tests
```bash
python -m unittest tests.test_integration_archive
```
Tests cover:
- SharedData + Archive flow
- Buffer limits with archiving
- Persistence across restarts
- Backward compatibility
### Running All Tests
```bash
python -m unittest discover tests
```
## Migration Guide
### From v5.1 to v5.2
No migration needed! The feature is fully backward compatible:
1. Existing SharedData code works unchanged
2. Archive is optional (requires BLE address)
3. First run creates archive files automatically
4. No data loss from existing cache
### Upgrading Existing Installation
```bash
# No special steps needed
python meshcore_gui.py literal:AA:BB:CC:DD:EE:FF
```
Archive files will be created automatically on first message/rxlog.
## Future Enhancements (Out of Scope for v1.0)
- Full-text search in archive
- Export to CSV/JSON
- Compression of old messages
- Cloud sync / multi-device sync
- Web interface for archive browsing
- Advanced filtering and queries
## Troubleshooting
### Archive Not Created
**Problem:** No `~/.meshcore-gui/archive/` directory
**Solution:**
- Check that SharedData was initialized with BLE address
- Check disk permissions
- Enable debug mode: `--debug-on`
### Cleanup Not Running
**Problem:** Old messages not removed
**Solution:**
- Cleanup runs every 24 hours
- Manually trigger: `shared.archive.cleanup_old_data()`
- Check retention config values
### High Disk Usage
**Problem:** Archive files growing too large
**Solution:**
- Reduce `MESSAGE_RETENTION_DAYS` in config
- Run manual cleanup
- Check for misconfigured retention values

Retention strategy
~~~~~~~~~~~~~~~~~~
- Messages older than MESSAGE_RETENTION_DAYS are purged daily
