Synchronization management for the Dash SPV client. +//! +//! This module provides different sync strategies: +//! +//! 1. **Sequential sync**: Headers first, then filter headers, then filters on-demand +//! 2. **Interleaved sync**: Headers and filter headers synchronized simultaneously +//! for better responsiveness and efficiency +//! +//! The interleaved sync mode requests filter headers immediately after each batch +//! of headers is received and stored, providing better user experience during +//! initial sync operations. + +pub mod headers; +pub mod filters; +pub mod masternodes; +pub mod state; + + +use crate::client::ClientConfig; +use crate::error::{SyncError, SyncResult}; +use crate::network::NetworkManager; +use crate::storage::StorageManager; +use crate::types::SyncProgress; +use dashcore::network::constants::NetworkExt; + +pub use headers::HeaderSyncManager; +pub use filters::FilterSyncManager; +pub use masternodes::MasternodeSyncManager; +pub use state::SyncState; + +/// Coordinates all synchronization activities. +pub struct SyncManager { + header_sync: HeaderSyncManager, + filter_sync: FilterSyncManager, + masternode_sync: MasternodeSyncManager, + state: SyncState, + config: ClientConfig, +} + +impl SyncManager { + /// Create a new sync manager. + pub fn new(config: &ClientConfig, received_filter_heights: std::sync::Arc>>) -> Self { + Self { + header_sync: HeaderSyncManager::new(config), + filter_sync: FilterSyncManager::new(config, received_filter_heights), + masternode_sync: MasternodeSyncManager::new(config), + state: SyncState::new(), + config: config.clone(), + } + } + + /// Handle a Headers message by routing it to the header sync manager. + /// If filter headers are enabled, also requests filter headers for new blocks. + pub async fn handle_headers_message( + &mut self, + headers: Vec, + storage: &mut dyn StorageManager, + network: &mut dyn NetworkManager, + ) -> SyncResult { + // First, let the header sync manager process the headers + let continue_sync = self.header_sync.handle_headers_message(headers.clone(), storage, network).await?; + + // If filters are enabled and we received new headers, request filter headers for them + if self.config.enable_filters && !headers.is_empty() { + // Get the height range of the newly stored headers + let first_header_hash = headers[0].block_hash(); + let last_header_hash = headers.last().unwrap().block_hash(); + + // Find heights for these headers + if let Some(first_height) = storage.get_header_height_by_hash(&first_header_hash).await + .map_err(|e| SyncError::SyncFailed(format!("Failed to get first header height: {}", e)))?
