Update Management Guide [AIR-3][AIS-3][AIT-3][RES-3]¶

Comprehensive update management for Anya-core extensions, ensuring seamless upgrades while maintaining Bitcoin BIP compliance, Web5 protocol compatibility, and ML model integrity.

Overview¶

The Anya-core update system provides automated and manual update mechanisms for extensions, core components, and dependencies. All updates maintain backward compatibility and security standards while following semantic versioning principles.

Update Categories¶

Core System Updates¶

• Anya-core Engine: Core Bitcoin, Web5, and ML functionality
• Extension Runtime: Extension execution environment
• Security Patches: Critical security vulnerability fixes
• BIP Compliance: Bitcoin Improvement Proposal implementations
• Protocol Updates: Web5 and ML protocol enhancements

Extension Updates¶

• Feature Updates: New functionality and capabilities
• Bug Fixes: Issue resolution and stability improvements
• Performance Optimizations: Speed and efficiency enhancements
• Dependency Updates: Third-party library upgrades
• Configuration Changes: Settings and parameter adjustments

Update Monitoring¶

Update Metrics and Logging¶

use prometheus::{Counter, Histogram, Gauge};

lazy_static! {
    static ref UPDATE_ATTEMPTS: Counter = register_counter!(
        "anya_updates_total",
        "Total number of update attempts"
    ).unwrap();

    static ref UPDATE_DURATION: Histogram = register_histogram!(
        "anya_update_duration_seconds",
        "Time spent performing updates"
    ).unwrap();

    static ref UPDATE_FAILURES: Counter = register_counter!(
        "anya_update_failures_total",
        "Total number of failed updates"
    ).unwrap();

    static ref ROLLBACK_OPERATIONS: Counter = register_counter!(
        "anya_rollbacks_total",
        "Total number of rollback operations"
    ).unwrap();
}

pub struct UpdateMonitor {
    logger: Logger,
    metrics_collector: MetricsCollector,
}

impl UpdateMonitor {
    pub async fn monitor_update<F>(&self, component: &str, version: &Version, operation: F) -> Result<UpdateResult, UpdateError>
    where
        F: Future<Output = Result<UpdateResult, UpdateError>>,
    {
        let start_time = Instant::now();
        UPDATE_ATTEMPTS.inc();

        info!(self.logger, "Starting update";
              "component" => component,
              "version" => %version);

        let result = operation.await;
        let duration = start_time.elapsed();

        UPDATE_DURATION.observe(duration.as_secs_f64());

        match &result {
            Ok(update_result) => {
                info!(self.logger, "Update completed successfully";
                      "component" => component,
                      "version" => %version,
                      "duration" => ?duration);
            }
            Err(error) => {
                UPDATE_FAILURES.inc();
                error!(self.logger, "Update failed";
                       "component" => component,
                       "version" => %version,
                       "error" => %error,
                       "duration" => ?duration);
            }
        }

        result
    }
}

Best Practices¶

Update Safety Guidelines¶

1. Always Create Rollback Points: Before any update
2. Test in Staging: Validate updates in non-production environments
3. Incremental Updates: Apply updates in small, manageable chunks
4. Monitor After Updates: Watch for issues post-deployment
5. Security First: Prioritize security updates over feature updates

Update Scheduling¶

pub struct UpdateScheduleOptimizer {
    system_monitor: SystemMonitor,
    load_predictor: LoadPredictor,
}

impl UpdateScheduleOptimizer {
    pub async fn find_optimal_update_time(&self, update: &UpdateInfo) -> Result<DateTime<Utc>, ScheduleError> {
        // Analyze system load patterns
        let load_pattern = self.load_predictor.predict_load_pattern().await?;

        // Find low-load periods
        let low_load_windows = load_pattern.find_low_load_windows(Duration::from_hours(2));

        // Consider maintenance windows
        let maintenance_windows = self.get_maintenance_windows().await?;

        // Find intersection of low-load and maintenance windows
        let optimal_windows = self.intersect_windows(&low_load_windows, &maintenance_windows);

        // Choose earliest optimal window
        optimal_windows.into_iter()
            .min()
            .ok_or(ScheduleError::NoOptimalTime)
    }
}

Dependency Management¶

#[derive(Debug, Clone)]
pub struct DependencyGraph {
    components: HashMap<String, Component>,
    dependencies: HashMap<String, Vec<String>>,
}

impl DependencyGraph {
    pub fn calculate_update_order(&self, components_to_update: &[String]) -> Result<Vec<String>, DependencyError> {
        let mut update_order = Vec::new();
        let mut visited = HashSet::new();
        let mut visiting = HashSet::new();

        for component in components_to_update {
            self.topological_sort(component, &mut update_order, &mut visited, &mut visiting)?;
        }

        Ok(update_order)
    }

    fn topological_sort(
        &self,
        component: &str,
        order: &mut Vec<String>,
        visited: &mut HashSet<String>,
        visiting: &mut HashSet<String>,
    ) -> Result<(), DependencyError> {
        if visiting.contains(component) {
            return Err(DependencyError::CircularDependency(component.to_string()));
        }

        if visited.contains(component) {
            return Ok(());
        }

        visiting.insert(component.to_string());

        if let Some(dependencies) = self.dependencies.get(component) {
            for dependency in dependencies {
                self.topological_sort(dependency, order, visited, visiting)?;
            }
        }

        visiting.remove(component);
        visited.insert(component.to_string());
        order.push(component.to_string());

        Ok(())
    }
}
