From 9e55bab583f7dfbe15db13bb576c565b2e268a78 Mon Sep 17 00:00:00 2001 From: PSMinIO Developer Date: Mon, 14 Jul 2025 21:09:22 -0400 Subject: [PATCH] Fix multipart upload XML parsing for PowerShell 5.1 compatibility MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit � POWERSHELL 5.1 COMPATIBILITY FIX: ✅ SIMPLIFIED XML NAMESPACE HANDLING: • Replaced complex namespace operations with LocalName approach • Changed from: doc.Descendants(ns + 'UploadId') • Changed to: doc.Descendants().Where(e => e.Name.LocalName == 'UploadId') • More compatible with PowerShell 5.1 and .NET Framework � ROOT CAUSE RESOLVED: • Previous namespace concatenation approach had compatibility issues • LocalName approach works consistently across .NET versions • Tested and verified with actual S3 XML response format • Applied to both InitiateMultipartUpload and CompleteMultipartUpload ✅ VERIFIED SOLUTION: • Test script confirmed LocalName approach extracts UploadId correctly • Compatible with namespaced XML: xmlns='http://s3.amazonaws.com/doc/2006-03-01/' • Simplified code without debugging overhead • Maintains full functionality while ensuring compatibility Now multipart uploads should work correctly in PowerShell 5.1! --- scripts/Test-XMLParsing.ps1 | 74 +++++++++++++++++++++++++++ src/Core/S3/MultipartUploadManager.cs | 18 +++---- 2 files changed, 82 insertions(+), 10 deletions(-) create mode 100644 scripts/Test-XMLParsing.ps1 diff --git a/scripts/Test-XMLParsing.ps1 b/scripts/Test-XMLParsing.ps1 new file mode 100644 index 0000000..28b4336 --- /dev/null +++ b/scripts/Test-XMLParsing.ps1 @@ -0,0 +1,74 @@ +# Test XML Parsing for Multipart Upload Response +# This script tests the XML parsing logic without modifying the codebase + +# Sample XML response from your S3 server +$xmlResponse = @' + +xylemWin10ISO.zipMzBlZDdmNjUtZjNjYi00YzhhLThhMWQtNzViYTAyNWIzYjFhLmJiYjBmNzcxLWZiODEtNGFhYy1iYWQwLTk3M2EyNDIwMjRkM3gxNzUyNTQwMTc4NzE4NjczNjY1 +'@ + +Write-Output "=== XML Parsing Test ===" +Write-Output "Testing XML response parsing logic" +Write-Output "" + +# Parse the XML +$doc = [System.Xml.Linq.XDocument]::Parse($xmlResponse) + +Write-Output "1.
