From 6dddb2345b91a4701ccaa85eecb3ce8261d3780b Mon Sep 17 00:00:00 2001 From: Stacy Gaikovaia Date: Tue, 13 Oct 2020 10:44:26 -0400 Subject: valgrind: drd: fix pthread intercept test failures After glibc uprev 2.31 -> 2.32, the following drd ptests fail with the error "condition variable has not been initialized". drd/tests/annotate_hb_err drd/tests/annotate_sem drd/tests/annotate_rwlock drd/tests/annotate_order_2 drd/tests/annotate_smart_pointer drd/tests/annotate_spinlock drd/tests/monitor_example drd/tests/pth_cond_race drd/tests/pth_inconsistent_cond_wait In glibc 2.32, the POSIX thread functions are in both libc and libpthread, causing valgrind to misinterpert test behaviour. This patch tells valgrind to intercept both the libc and the libpthread functions, resolving these ptest failures. Here are the latest test results on qemux86-64: === Test Summary === TOTAL: 728 PASSED: 688 FAILED: 1 SKIPPED: 39 The failed test is in helgrind: FAIL: helgrind/tests/pth_destroy_cond Patch can be removed once we uprev valgrind. See valgrind commit 15330adf7c2471fbaa6a0818db07078d81dbff97.
