| # Test 3: The exact scenario from GH #179 — socketpair with dup'd fd | ||
| # This would hang without the fix because the dup'd write handle stays open. |

There was a problem hiding this comment.
We need to bump the minimal version for Overload::FileCheck to be 0.014 to make sure every users got the correct fix.

Tests that file check operators (-S, -f, etc.) on real filehandles do not retain references that prevent garbage collection. Includes the exact socketpair scenario from the bug report where a dup'd write handle kept alive by a leaked ref caused reads to hang. Root cause is in Overload::FileCheck's $_last_call_for variable.

The root cause is in
Overload::FileCheck— the$_last_call_forvariable stored filehandle references, preventing garbage collection. The fix is in cpanel/Overload-FileCheck#25.This PR adds regression tests on the Test::MockFile side to ensure the issue stays fixed.
