From f9687c5ec24e2a8755a8fe6fe5088dc37c451bf6 Mon Sep 17 00:00:00 2001 From: Jamie Pine Date: Thu, 9 Oct 2025 09:30:34 -0700 Subject: [PATCH] refactor: Update sync transport implementation and library creation methods - Revised documentation in the NetworkTransport trait to clarify the source of target device UUIDs and connected partners, switching references from the obsolete sync_partners table to the devices table. - Introduced `create_library_no_sync` method in LibraryManager to allow library creation without automatic sync initialization, facilitating testing with mock transports. - Enhanced logging in PeerSync to include network transport details for better debugging. - Updated MockNetworkTransport to support transport name retrieval for improved test clarity. --- core/src/infra/sync/transport.rs | 49 ++----- core/src/library/manager.rs | 59 +++++--- core/src/library/mod.rs | 5 + core/src/service/sync/peer.rs | 23 ++- core/tests/SYNC_DEBUG_RESULTS.md | 213 ++++++++++++++++++++++++++++ core/tests/sync_integration_test.rs | 113 ++++++++------- 6 files changed, 352 insertions(+), 110 deletions(-) create mode 100644 core/tests/SYNC_DEBUG_RESULTS.md diff --git a/core/src/infra/sync/transport.rs b/core/src/infra/sync/transport.rs index 75e9c3050..063a1f416 100644 --- a/core/src/infra/sync/transport.rs +++ b/core/src/infra/sync/transport.rs @@ -44,7 +44,7 @@ pub trait NetworkTransport: Send + Sync { /// /// # Arguments /// - /// * `target_device` - UUID of the target device (from sync_partners table) + /// * `target_device` - UUID of the target device (from devices table where sync_enabled=true) /// * `message` - The sync message to send (StateChange, SharedChange, etc.) /// /// # Returns @@ -72,7 +72,7 @@ pub trait NetworkTransport: Send + Sync { /// Get list of currently connected sync partner devices /// /// Returns UUIDs of devices that are: - /// - Listed in sync_partners table with sync_enabled=true + /// - Listed in devices table with sync_enabled=true /// - Currently connected (have active network connection) /// /// This is used to optimize broadcasting - only send to devices that can receive. @@ -85,7 +85,7 @@ pub trait NetworkTransport: Send + Sync { /// # Implementation Note /// /// This should query: - /// 1. `sync_partners` table for enabled partners + /// 1. `devices` table for sync_enabled=true devices /// 2. `device_registry` for connection status /// 3.
