From 1ea859263dbb0dc6e7ae24d4568b344e1aa14855 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 8 Nov 2025 17:42:53 +0000 Subject: [PATCH 1/8] Refactor: Extract internal types from SyncEngine.cs into separate files Extracted 8 internal types from SyncEngine.cs (1,110 lines) into separate files to improve code organization and maintainability: - ChangeSet.cs: Represents a set of changes detected during synchronization - IChange.cs: Interface for change types - AdditionChange.cs: Represents new file/directory additions - ModificationChange.cs: Represents modifications to existing items - DeletionChange.cs: Represents file/directory deletions - SyncActionType.cs: Enum defining synchronization action types - SyncAction.cs: Represents a synchronization action to be performed - ActionGroups.cs: Organizes sync actions into optimized processing groups All extracted types maintain the internal visibility modifier and proper namespaces (Oire.SharpSync.Sync). SyncEngine.cs reduced from 1,110 to 1,035 lines (75 lines removed). This refactoring improves code maintainability by separating concerns and making the codebase easier to navigate. --- src/SharpSync/Sync/ActionGroups.cs | 22 +++++++ src/SharpSync/Sync/AdditionChange.cs | 12 ++++ src/SharpSync/Sync/ChangeSet.cs | 15 +++++ src/SharpSync/Sync/DeletionChange.cs | 13 ++++ src/SharpSync/Sync/IChange.cs | 8 +++ src/SharpSync/Sync/ModificationChange.cs | 13 ++++ src/SharpSync/Sync/SyncAction.cs | 15 +++++ src/SharpSync/Sync/SyncActionType.cs | 12 ++++ src/SharpSync/Sync/SyncEngine.cs | 75 ------------------------ 9 files changed, 110 insertions(+), 75 deletions(-) create mode 100644 src/SharpSync/Sync/ActionGroups.cs create mode 100644 src/SharpSync/Sync/AdditionChange.cs create mode 100644 src/SharpSync/Sync/ChangeSet.cs create mode 100644 src/SharpSync/Sync/DeletionChange.cs create mode 100644 src/SharpSync/Sync/IChange.cs create mode 100644 src/SharpSync/Sync/ModificationChange.cs create mode 100644 src/SharpSync/Sync/SyncAction.cs create mode 100644 src/SharpSync/Sync/SyncActionType.cs diff --git a/src/SharpSync/Sync/ActionGroups.cs b/src/SharpSync/Sync/ActionGroups.cs new file mode 100644 index 0000000..449a7ee --- /dev/null +++ b/src/SharpSync/Sync/ActionGroups.cs @@ -0,0 +1,22 @@ +namespace Oire.SharpSync.Sync;

This allows users to see detailed file-by-file information about what will happen during sync. Changes: 1. **New Public API in Core namespace:** - SyncActionType enum: Defines action types (Download, Upload, DeleteLocal, DeleteRemote, Conflict) - moved from internal Sync namespace to public Core - SyncPlanAction class: Represents a planned action with file details including path, size, type, last modified date, conflict info, and human-readable description - SyncPlan class: Contains comprehensive sync plan with actions grouped by type, statistics (counts, sizes), and summary information 2. **Enhanced ISyncEngine interface:** - Added GetSyncPlanAsync() method that returns detailed SyncPlan - Provides file-level preview information for desktop clients - Complements existing PreviewSyncAsync() which returns summary counts 3. **SyncEngine implementation:** - Implemented GetSyncPlanAsync() to perform change detection and convert internal actions to public SyncPlanAction objects - Maintains separation between internal implementation details and public API Features for Desktop Clients: - File-by-file action preview with sizes and types - Human-readable descriptions (e.g., "Download document.pdf (1.2 MB)") - Actions grouped by type (downloads, uploads, deletes, conflicts) - Total counts and data transfer sizes - Summary strings for quick display (e.g., "3 downloads (2.5 MB), 2 uploads (1.2 MB)") - Priority information for showing sync order This enhancement maintains backward compatibility while providing rich preview capabilities needed for desktop application development. --- src/SharpSync/Core/ISyncEngine.cs | 13 +++ src/SharpSync/Core/SyncActionType.cs | 35 +++++++ src/SharpSync/Core/SyncPlan.cs | 138 +++++++++++++++++++++++++++ src/SharpSync/Core/SyncPlanAction.cs | 87 +++++++++++++++++ src/SharpSync/Sync/SyncActionType.cs | 12 --- src/SharpSync/Sync/SyncEngine.cs | 66 +++++++++++++ 6 files changed, 339 insertions(+), 12 deletions(-) create mode 100644 src/SharpSync/Core/SyncActionType.cs create mode 100644 src/SharpSync/Core/SyncPlan.cs create mode 100644 src/SharpSync/Core/SyncPlanAction.cs delete mode 100644 src/SharpSync/Sync/SyncActionType.cs diff --git a/src/SharpSync/Core/ISyncEngine.cs b/src/SharpSync/Core/ISyncEngine.cs index cd544c4..fcfc5a4 100644 --- a/src/SharpSync/Core/ISyncEngine.cs +++ b/src/SharpSync/Core/ISyncEngine.cs @@ -29,6 +29,19 @@ public interface ISyncEngine: IDisposable { /// Task PreviewSyncAsync(SyncOptions? options = null, CancellationToken cancellationToken = default); + /// + /// Gets a detailed plan of synchronization actions that will be performed + /// + /// Optional synchronization options + /// Cancellation token to cancel the operation + /// A detailed sync plan with all planned actions + /// + /// This method performs change detection and returns a detailed plan of what will happen during synchronization, + /// without actually modifying any files.

Previously, deletion detection only checked items missing from BOTH storages, missing single-sided deletions. Changes: 1. Enhanced ChangeSet with separate LocalPaths and RemotePaths HashSets - LocalPaths tracks items found in local storage during scan - RemotePaths tracks items found in remote storage during scan - ProcessedPaths remains for general tracking 2. Updated ScanDirectoryRecursiveAsync to populate LocalPaths/RemotePaths - When scanning local storage, adds to LocalPaths - When scanning remote storage, adds to RemotePaths - This gives us accurate per-side existence information 3. Rewrote deletion detection logic in DetectChangesAsync - Old: Only checked items NOT in ProcessedPaths (both storages) - New: Checks ALL tracked DB items against LocalPaths and RemotePaths - Correctly detects single-sided deletions: * File in DB + remote but not local → DeletedLocally=true → DeleteRemote * File in DB + local but not remote → DeletedRemotely=true → DeleteLocal * File in DB but neither side → DeletedLocally=true, DeletedRemotely=true This fixes the test scenario: 1. Create file locally 2. SynchronizeAsync() uploads to remote + updates DB 3. Delete local file 4.
