木头云 2593213d9c Fix FreeBSD shm_unlink failure by adding '/' prefix in remove() ... Problem: Tests fail on the second run on FreeBSD with ShmTest.RemoveByName failing. After the first test run completes, subsequent runs fail because shared memory objects are not properly removed. Root cause: FreeBSD's shm_unlink() is stricter than Linux about POSIX compliance. The remove(char const * name) function was calling shm_unlink() without the '/' prefix, while acquire() was using '/'+name format. This inconsistency caused: - Linux: Silently tolerates both /name and name formats - FreeBSD: Strictly requires /name format, shm_unlink("name") fails When shm_unlink() fails to remove the shared memory object: 1. First test run creates /remove_by_name_test_1 2. Test calls shm::remove("remove_by_name_test_1") 3. shm_unlink("remove_by_name_test_1") fails on FreeBSD (missing '/') 4. Shared memory object remains in the system 5. Second test run tries to reuse the same name -> conflict -> test fails Solution: 1. Fix remove(char const * name) to prepend '/' to the name for consistency with acquire() function, ensuring POSIX compliance 2. Add error checking for all shm_unlink() calls to log failures with errno This ensures proper cleanup on FreeBSD and maintains compatibility with Linux. Changes: - Modified remove(char const * name) to use '/'+name format - Added error logging for all three shm_unlink() calls - Now consistent with POSIX requirement: shared memory names must be /somename Tested on FreeBSD 15: Multiple consecutive test runs now pass without failures.		2025-12-06 07:20:33 +00:00
