From ae92f70d1e19641c686f3ba6523bb0d25ecd84fe Mon Sep 17 00:00:00 2001 From: Geoff Franks Date: Tue, 26 May 2026 14:48:11 -0400 Subject: [PATCH] Fix Windows unit test compatibility and port management Addresses Windows-specific test failures in fake app/proxy unit tests: 1. **Signal Handling Fix**: - Added cross-platform signal handling for SIGTERM tests - Windows: expect exit code 42 (natural termination) - Unix: expect exit code 143 (128 + SIGTERM signal 15) 2. **Port Management Improvements**: - Added aggressive session cleanup with defer functions - Added Windows-specific delays to allow port release - Ensures all test processes are properly terminated - Prevents "Only one usage of each socket address" errors 3. **Session Lifecycle Management**: - Added proper session cleanup to all unit tests - Kill any remaining processes after test completion - Cross-platform cleanup timing adjustments These changes ensure unit tests pass on both Windows and Unix platforms while maintaining the same test behavior and coverage.
