## Implementation Notes (Phase 6)
|
||||
|
||||
This section documents the final implementation as of Phase 6 (Observability & Production Readiness).
|
||||
|
||||
### What Was Actually Built
|
||||
|
||||
The implementation closely follows the design document with the following completed components:
|
||||
|
||||
#### Phase 1: Basic Sync (commit b167f1b)
|
||||
- [`SyncManager`](../../src/sync/manager.rs) - Main coordinator for proactive sync
|
||||
- Single relay sync via `NGIT_SYNC_RELAY_URL` configuration
|
||||
- Event validation through existing [`Nip34WritePolicy`](../../src/nostr/builder.rs)
|
||||
|
||||
#### Phase 2: Three-Layer Filters (commit bf558b0)
|
||||
- [`FilterService`](../../src/sync/filter.rs) - Builds three-layer filter strategy
|
||||
- Layer 1: All kind 30617+30618 (announcements)
|
||||
- Layer 2: A/a tag filters for repository events
|
||||
- Layer 3: E/e tag filters for related events (PRs, Issues)
|
||||
- Multi-relay discovery from stored announcements
|
||||
|
||||
#### Phase 3: Health Tracking (commit f639ecf)
|
||||
- [`RelayHealthTracker`](../../src/sync/health.rs) - DashMap-based health tracking
|
||||
- Three states: Healthy → Degraded → Dead
|
||||
- Exponential backoff: 5s → 10s → 20s → ... → max (default 1h)
|
||||
- Dead relay detection after 24h continuous failures
|
||||
- Startup jitter (0-10s) to prevent thundering herd
|
||||
|
||||
#### Phase 4: Dynamic Subscriptions (commit a19ff57)
|
||||
- [`SubscriptionManager`](../../src/sync/subscription.rs) - Per-connection subscription tracking
|
||||
- Dynamic Layer 2 subscriptions when new announcements arrive
|
||||
- Dynamic Layer 3 subscriptions when new PRs/Issues arrive
|
||||
- Filter consolidation at threshold (150 filters)
|
||||
|
||||
#### Phase 5: Catchup & Gap Detection (commit 950c2e4)
|
||||
- [`NegentropyService`](../../src/sync/negentropy.rs) - Gap-filling catchup operations
|
||||
- Startup catchup (configurable delay)
|
||||
- Reconnection catchup (limited lookback)
|
||||
- Daily catchup (not yet implemented - placeholder)
|
||||
|
||||
#### Phase 6: Observability (this phase)
|
||||
- [`SyncMetrics`](../../src/sync/metrics.rs) - Full Prometheus integration
|
||||
- Grafana dashboard panels for sync monitoring
|
||||
- Documentation updates
|
||||
|
||||
### Differences from Original Design
|
||||
|
||||
1. **Negentropy (NIP-77)**: Simplified gap-filling was used instead of full NIP-77 negentropy reconciliation, as nostr-sdk 0.44 lacks built-in negentropy support. The current implementation uses timestamp-based catchup queries.
|
||||
|
||||
2. **Filter Consolidation Threshold**: Set at 150 filters (as designed) based on typical relay filter limits.
|
||||
|
||||
3. **Health Tracking**: Implemented exactly as designed - in-memory only (not persisted to database), which is acceptable for production as health state rebuilds quickly on restart.
|
||||
|
||||
4. **Metric Label Strategy**: Used simpler numeric encoding for health status (1=healthy, 2=degraded, 3=dead) instead of multiple label values per relay, reducing cardinality.
|
||||
|
||||
5. **Event Source Tracking**: Implemented four source types (`live`, `startup`, `reconnect`, `daily`) instead of the original (`direct`, `live_sync`, `catchup`, `daily_catchup`).
|
||||
|
||||
### Three-Layer Filter Strategy (As Implemented)
|
||||
|
||||
```
|
||||
Layer 1: Discovery Layer
|
||||
├── Query: kinds [30617, 30618] (announcements)
|
||||
├── Applied: At startup and during sync
|
||||
└── Purpose: Discover all repositories across network
|
||||
|
||||
Layer 2: Repository Events
|
||||
├── Query: Events with A/a tags pointing to tracked repos
|
||||
├── Format: A tag = "30617:<pubkey>:<identifier>"
|
||||
├── Triggered: When new announcement is accepted
|
||||
└── Purpose: Get PRs, issues, patches for repositories
|
||||
|
||||
Layer 3: Related Events
|
||||
├── Query: Events with E/e tags pointing to tracked PRs/Issues
|
||||
├── Triggered: When new PR/Issue is accepted
|
||||
└── Purpose: Get comments, reviews, status updates
|
||||
```
|
||||
|
||||
### Prometheus Metrics (As Implemented)
|
||||
|
||||
| Metric | Type | Labels | Description |
|
||||
|--------|------|--------|-------------|
|
||||
| `ngit_sync_relay_connected` | Gauge | relay | Connection status (1/0) |
|
||||
| `ngit_sync_connection_attempts_total` | Counter | relay, result | Attempts by outcome |
|
||||
| `ngit_sync_relay_status` | Gauge | relay | Health state (1/2/3) |
|
||||
| `ngit_sync_relay_failures` | Gauge | relay | Consecutive failures |
|
||||
| `ngit_sync_events_total` | Counter | source | Events by source type |
|
||||

||||
| `ngit_sync_relays_connected_total` | Gauge | - | Currently connected |
|
||||

||||
|
||||
### Configuration Options (As Implemented)
|
||||

### Proactive Sync Configuration (GRASP-02)
|
||||
|
||||
These options configure the proactive sync feature that synchronizes events from other relays.
|
||||
|
||||
#### `NGIT_SYNC_RELAY_URL`
|
||||
|
||||
**Description:** URL of the primary relay to sync events from
|
||||
**Type:** String (WebSocket URL)
|
||||
**Default:** None (sync disabled)
|
||||
**Required:** No
|
||||
|
||||
**Examples:**
|
||||
```bash
|
||||
# Sync from a public relay
|
||||
NGIT_SYNC_RELAY_URL=wss://relay.example.com
|
||||
|
||||
# Sync from another GRASP relay
|
||||
NGIT_SYNC_RELAY_URL=wss://git.nostr.dev
|
||||
|
||||
# Local testing
|
||||
NGIT_SYNC_RELAY_URL=ws://127.0.0.1:8081
|
||||
```
|
||||
|
||||
**Notes:**
|
||||
- When set, enables proactive sync feature
|
||||
- The relay will discover additional relays from repository announcements
|
||||
- Synced events go through the same validation as directly-submitted events
|
||||
- Use WebSocket protocol (`ws://` or `wss://`)
|
||||
|
||||
---
|
||||
|
||||
#### `NGIT_SYNC_MAX_BACKOFF_SECS`
|
||||
|
||||
**Description:** Maximum backoff time in seconds for sync relay reconnection
|
||||
**Type:** Integer (seconds)
|
||||
**Default:** `3600` (1 hour)
|
||||
**Required:** No
|
||||
|
||||
**Examples:**
|
||||
```bash
|
||||
# Default: 1 hour max backoff
|
||||
NGIT_SYNC_MAX_BACKOFF_SECS=3600
|
||||
|
||||
# Aggressive: 5 minute max backoff
|
||||
NGIT_SYNC_MAX_BACKOFF_SECS=300
|
||||
|
||||
# Conservative: 2 hour max backoff
|
||||
NGIT_SYNC_MAX_BACKOFF_SECS=7200
|
||||
```
|
||||
|
||||
**Notes:**
|
||||
- Backoff starts at 5 seconds and doubles on each failure
|
||||
- Capped at this maximum value
|
||||
- After 24 hours of failures, relay is marked "dead" and retried daily
|
||||
- Lower values mean more reconnection attempts
|
||||
|
||||
---
|
||||
|
||||
#### `NGIT_SYNC_STARTUP_DELAY_SECS`
|
||||
|
||||
**Description:** Delay in seconds before running startup catchup
|
||||
**Type:** Integer (seconds)
|
||||
**Default:** `30`
|
||||
**Required:** No
|
||||
|
||||
**Examples:**
|
||||
```bash
|
||||
# Default: 30 second delay
|
||||
NGIT_SYNC_STARTUP_DELAY_SECS=30
|
||||
|
||||
# Quick startup (testing)
|
||||
NGIT_SYNC_STARTUP_DELAY_SECS=5
|
||||
|
||||
# Production: longer warm-up
|
||||
NGIT_SYNC_STARTUP_DELAY_SECS=60
|
||||
```
|
||||
|
||||
**Notes:**
|
||||
- Allows connections to stabilize before catchup
|
||||
- Reduces load on remote relays at startup
|
||||
- Set to 0 for immediate catchup (not recommended)
|
||||
|
||||
---
|
||||
|
||||
#### `NGIT_SYNC_RECONNECT_DELAY_SECS`
|
||||
|
||||
**Description:** Delay in seconds before running catchup after reconnection
|
||||
**Type:** Integer (seconds)
|
||||
**Default:** `10`
|
||||
**Required:** No
|
||||
|
||||
**Examples:**
|
||||
```bash
|
||||
# Default: 10 second delay
|
||||
NGIT_SYNC_RECONNECT_DELAY_SECS=10
|
||||
|
||||
# Quick reconnect catchup
|
||||
NGIT_SYNC_RECONNECT_DELAY_SECS=5
|
||||
|
||||
# Conservative
|
||||
NGIT_SYNC_RECONNECT_DELAY_SECS=30
|
||||
```
|
||||
|
||||
**Notes:**
|
||||
- Prevents rate limiting from remote relays
|
||||
- Applied after each successful reconnection
|
||||
- Only catches up on recent events (see lookback days)
|
||||
|
||||
---
|
||||
|
||||
#### `NGIT_SYNC_RECONNECT_LOOKBACK_DAYS`
|
||||
|
||||
**Description:** Number of days to look back for reconnect catchup
|
||||
**Type:** Integer (days)
|
||||
**Default:** `3`
|
||||
**Required:** No
|
||||
|
||||
**Examples:**
|
||||
```bash
|
||||
# Default: 3 days lookback
|
||||
NGIT_SYNC_RECONNECT_LOOKBACK_DAYS=3
|
||||
|
||||
# Short lookback (frequent reconnects expected)
|
||||
NGIT_SYNC_RECONNECT_LOOKBACK_DAYS=1
|
||||
|
||||
# Extended lookback
|
||||
NGIT_SYNC_RECONNECT_LOOKBACK_DAYS=7
|
||||
```
|
||||
|
||||
**Notes:**
|
||||
- Limits catchup queries to recent events only
|
||||
- Reduces load compared to full historical sync
|
||||
- Balance between completeness and performance
|
||||
- Longer lookback useful for less reliable connections
