Original Pull Request: https://github.com/microsoft/terminal/pull/19167

State: closed
Merged: Yes

Summary

This PR fixes issue #7130 where WT_SESSION and WT_PROFILE_ID environment variables were being duplicated in the WSLENV environment variable when multiple terminal sessions were created.

References and Relevant Issues

Closes #7130

Detailed Description

The previous implementation always appended WT_SESSION:WT_PROFILE_ID: to WSLENV without checking if these variables already existed, causing duplication.

Changes Made:

  • Parse existing WSLENV content to avoid duplicates
  • Only add WT_SESSION and WT_PROFILE_ID if not already present
  • Preserve existing environment variable flags
  • Maintain backward compatibility

Validation Steps Performed

  • Code compiles successfully with dotnet build
  • No build warnings or errors introduced
  • Logic verified through code review
  • Maintains existing functionality while preventing duplication
