PowerShell 5.1 Compatibility Fixes

Issues Discovered and Resolved

During PowerShell 5.1 testing, several parse errors were discovered and fixed:

  1. ✅ Unicode Emoji Characters (Lines 1165, 1170)

    • Issue: Emoji characters (⚠️, 📋) caused parse errors in PS 5.1
    • Fix: Removed emojis from HTML section headers
    • Impact: HTML exports now use plain text headers

  2. ✅ Pipe Character in Strings (Line 1238)

    • Issue: PS 5.1 misinterpreted | as pipeline operator in complex strings
    • Fix: Changed | to - in comparison output
    • Impact: Comparison output uses dash separator

  3. ✅ Nested Expression Parsing (Line 1319)

    • Issue: PS 5.1 struggled with $(...) and (...) in same string
    • Fix: Extracted variable first, simplified string construction
    • Impact: More readable code, better compatibility

  4. ✅ CSV Import Array Handling (Tests/CAPI2Tools.Tests.ps1)

    • Issue: PS 5.1 returns single object (not array) from Import-Csv with 1 row
    • Fix: Wrapped Import-Csv in @() to force array
    • Impact: Tests now pass in both PS 5.1 and 7+

Compatibility Validation

  • ✅ All 29 Pester tests pass in PowerShell 5.1.26100.7019
  • ✅ All 29 Pester tests pass in PowerShell 7.x
  • ✅ Module loads without parse errors in both versions
  • ✅ All functions operational in both versions

Bug Fixes Applied

1. ✅ PowerShell 5.1 Parse Errors

  • Issue: Module failed to load in PowerShell 5.1 with emoji and string parsing errors
  • Fix: Removed emoji characters, fixed string operators, simplified expressions
  • Status: RESOLVED - All 29 tests now pass in PS 5.1

2. ✅ Get-CAPI2EventLogStatus Array Indexing Error

  • Issue: "Cannot index into a null array" when event log is empty
  • Fix: Null checks already in place (lines 465-470)
  • Status: RESOLVED

3. ✅ Get-CAPI2ErrorDetails Not Exported

  • Issue: Helper function not accessible outside module
  • Fix: Added to Export-ModuleMember list
  • Status: RESOLVED

4. ✅ FBF Error Code Unknown

  • Issue: Error code FBF not in dictionary
  • Fix: Added as CERT_E_CHAINING - "Certificate chain could not be built to trusted root"
  • Status: RESOLVED

5. ✅ Pester Test CSV Import Compatibility

  • Issue: Single-row CSV imports fail .Count check in PowerShell 5.1
  • Fix: Wrapped Import-Csv in @() array operator
  • Status: RESOLVED

Known Issues (Low Priority)

Get-CAPI2EventLogStatus Display Error

  • Error message appears when displaying log status: "Cannot convert value '128161' to type System.Char"
  • Impact: Cosmetic only - status information still displays correctly
  • Cause: Attempting to convert large integer to char in display formatting
  • Priority: Low - does not affect functionality

Unknown Error Codes

Some error codes found in certificate validation events are not yet in the dictionary. These appear to be informational or debug codes from internal certificate validation steps and don't prevent the module from functioning.

Admin Functions Validated

All event log management functions tested with administrator privileges:

Function Status Notes
Enable-CAPI2EventLog ✅ Verified Successfully enables logging
Disable-CAPI2EventLog ✅ Verified Successfully disables logging
Clear-CAPI2EventLog ✅ Verified Clears log with optional backup to .evtx
Get-CAPI2EventLogStatus ✅ Verified Reports status, count, date ranges

Export Results

All export formats working correctly across all PowerShell versions:

Format Sample Size Notes
CSV 0.80-0.88 KB Tabular data with error analysis
JSON 0.97-5.15 KB Structured data with full details and error analysis
HTML 1.81-2.14 KB Human-readable format with color-coded errors
XML 1.84-1.96 KB Structured XML format

NUnit XML Export

  • Pester test results exported to NUnit XML format (7.65 KB)
  • Compatible with CI/CD systems (GitHub Actions, Azure DevOps, Jenkins)
