Fix critical metrics calculation and aggressive disk flushing

Browse Source

� CRITICAL METRICS FIXES:

✅ DURATION & TIMING FIXES:
  • Fixed Duration showing 00:00:00 by calling Complete() before CreateResult()
  • Proper EndTime calculation ensures accurate duration metrics
  • AverageSpeed now calculated correctly from actual duration
  • Fixed metric calculation order to ensure proper timing

✅ AGGRESSIVE DISK FLUSHING:
  • Reduced flush threshold from 5MB to 1MB for more frequent updates
  • Time-based flushing every 500ms (was 1000ms) for real-time visibility
  • Added AggressiveFlush() method with reflection-based ZipArchive flushing
  • Force OS-level flush with FileStream.Flush(true) after each file
  • GC.Collect() to ensure all buffers are released immediately

✅ REAL-TIME FILE SIZE UPDATES:
  • ZipArchive internal stream flushing via reflection
  • Hybrid flushing: 1MB threshold OR 500ms intervals
  • Aggressive flush after every file completion
  • Multiple fallback flush strategies for reliability

✅ TECHNICAL IMPROVEMENTS:
  • Reflection-based access to ZipArchive._archiveStream for forced flushing
  • Error handling with fallback flush strategies
  • Proper Complete() call timing before result creation
  • Enhanced error recovery during flush operations

� EXPECTED RESULTS:
  • Zip files now show real-time size growth every 1MB or 500ms
  • Accurate Duration, EndTime, and AverageSpeed metrics
  • Proper CompressionRatio and SpaceSaved calculations
  • Visible progress on file system during long operations

No more 0-duration metrics or static file sizes!
