Summary

  • Fixes Windows CI failures in test_legend_comprehensive.exe and test_streamplot.exe
  • Adds platform-independent file system operation delays for Windows compatibility
  • Replaces error stop statements with traditional stop for better Windows runtime compatibility

Changes Made

  • Added windows_safe_delay() subroutine using cpu_time intrinsic for cross-platform delays
  • Added 100ms delays after savefig() calls to allow Windows file system operations to complete
  • Added 150ms delay for PDF operations which may require more time on Windows
  • Replaced error stop with explicit print + stop 1 for consistent behavior across platforms

Root Cause Analysis

Windows CI failures were likely caused by:

  1. File system timing: Windows filesystem operations may be slower than Linux, causing file validation to fail before files are fully written
  2. Runtime differences: error stop behavior differs between compilers/platforms
  3. I/O buffering: Different file I/O buffering behavior on Windows vs Linux

Testing Strategy

  • All delays use cpu_time intrinsic for platform independence
  • No external dependencies added
  • Maintains existing test validation logic
  • Should not impact Linux CI performance significantly

Fixes

This should resolve the Windows CI deadlock blocking PR merges in batch mode operation.

enhance: add comprehensive Windows CI diagnostics
3bdd697 
- Add detailed progress output to identify where Windows tests are failing
- Enhanced error reporting in test_legend_comprehensive
- Added step-by-step diagnostic output in test_streamplot
- Remove problematic getcwd() call that may not be available on Windows

This will help identify the specific failure point in Windows CI tests.
