[2.5.0] - 2026-02-07

Summary

Major performance optimization release with loading animations. Backup/restore operations are now 3-5x faster, session listing is instant, and all action buttons now show loading feedback.

✨ New Features

Loading Animations

  • All action buttons now display a spinning loader during operations
  • Dynamic button text shows current state (e.g., "Resetting...", "Creating...", "Deleting...")
  • Buttons are disabled during loading to prevent double-clicks

Reset Tab Loading States

  • Reset button: spinner + "Resetting..." during reset operation
  • Addons button: spinner + "Deleting..." during addon folder deletion
  • New ID button: spinner + "Generating..." during machine ID generation
  • Kill button: spinner + "Stopping..." during app termination
  • Launch button: spinner + "Launching..." during app launch

Sessions Tab Loading States

  • Create Backup button: spinner + "Creating..." during backup creation
  • Kill and Continue button: spinner + "Processing..." during kill + backup
  • Restore Session (context menu): spinner + "Restoring..." during restore
  • Delete button (per row): spinner + "Deleting..." during session deletion

Config Tab Loading States

  • Save button: spinner + "Saving..." during app configuration save
  • Delete button: spinner during app deletion
  • Active/Inactive toggle: spinner during status change

🚀 Performance Improvements

Parallel File Copying

  • Backup and restore now use a worker pool with all available CPU cores
  • Each worker uses optimized 4MB I/O buffers for maximum throughput
  • File operations run concurrently instead of sequentially

Streaming Hash Computation

  • Files are hashed while being copied using io.TeeReader
  • Eliminates the previous double-read pattern (copy then hash)
  • Reduces I/O by 50% during backup operations

Cached Metadata

  • Session size and file count now stored in .backup_meta.json
  • Session listing no longer walks directory trees to calculate size
  • Session list loads instantly regardless of backup size

Lazy Hash Verification

  • Hash verification removed from session listing (was blocking UI)
  • New on-demand VerifySessionIntegrity API for explicit integrity checks
  • Corrupted status no longer computed at list time

✨ New Features

Backend

  • Added VerifySessionIntegrity(appKey, sessionName) API for on-demand backup verification
  • Enhanced metadata schema with hash_version, size, and file_count fields
  • New v2 hash algorithm matching streaming computation

📝 Technical Changes

New Types

  • CopyJob - represents a file copy operation with source, destination, and relative path
  • FileCopyResult - holds copy result including size, hash, and error status
  • BackupMetadata - full metadata structure with cached values

New Functions

  • copyFileStreaming() - copies files while computing SHA256 in single pass
  • copyWithWorkerPool() - parallel file copying with worker pool
  • collectCopyJobs*() - job collection helpers for items and addons
  • computeHashFromResults() - aggregate hash from sorted file results
  • readBackupMetadataFull() - reads full metadata including cached size
  • computeBackupHashV2() - v2 hash algorithm for new backups

🔄 Backwards Compatibility

  • Old backups without cached size fall back to directory walk
  • Old hash format (v1) automatically detected and verified correctly
  • No migration required - old backups work seamlessly
