Scripts must start with #!/usr/bin/env <shell> for portability. Add set -e to top-level scripts. Add use warnings to perl scripts.

Tests #2/#3 are specifically for helgrind/drd tests. Test #1 should never be executed under valgrind, even if force-enabled via command-line options. Ref: pmem/issues#664

Ref: pmem/issues#639 Ref: pmem/issues#665 Apparently valgrind just can't handle the way jemalloc uses mutexes across forks, as demonstrated by this dummy program: $ cat dummy.c pthread_mutex_t dummy = PTHREAD_MUTEX_INITIALIZER; static void prefork(void) { pthread_mutex_lock(&dummy); } static void postfork_child(void) { pthread_mutexattr_t attr; if (pthread_mutexattr_init(&attr) != 0) abort(); if (pthread_mutex_init(&dummy, &attr) != 0) { pthread_mutexattr_destroy(&attr); abort(); } pthread_mutexattr_destroy(&attr); } static void postfork_parent(void) { pthread_mutex_unlock(&dummy); } int main() { pthread_atfork(prefork, postfork_parent, postfork_child); fork(); pthread_mutex_lock(&dummy); pthread_mutex_unlock(&dummy); } $ cc -pthread dummy.c -o dummy $ valgrind --tool=helgrind ./dummy 2>&1 | grep holds ==26890== Thread #1: Exiting thread still holds 1 lock $ valgrind --tool=drd ./dummy 2>&1 | grep -i mutex ==26898== Mutex reinitialization: mutex 0x30a040, recursion count 1, owner 1. ==26898== at 0x4C385F0: pthread_mutex_init ==26898== mutex 0x30a040 was first observed at: ==26898== at 0x4C390D3: pthread_mutex_lock ==26898== Recursive locking not allowed: mutex 0x30a040, recursion count 1, owner 1. ==26898== at 0x4C390D3: pthread_mutex_lock ==26898== mutex 0x30a040 was first observed at: ==26898== at 0x4C390D3: pthread_mutex_lock
