Details:
I find (with my xroot builds from git) that, XrdSysThread::Num() is returning
the PID, which is the same for all threads in the xrootd process.
From XrdSysPthread.cc the first block of these ifdefs is used:
#if defined(__linux__)
myNum = static_cast<unsigned int>(getpid());
#elif defined(__solaris__)
myNum = static_cast<unsigned int>(pthread_self());
#elif defined(__macos__)
myNum = static_cast<unsigned
int>(pthread_mach_thread_np(pthread_self()));
#else
static XrdSysMutex numMutex;
static unsigned long threadNum = 1;
numMutex.Lock(); threadNum++; myNum = threadNum; numMutex.UnLock();
#endif
I think the intention was that XrdSysThread::Num() would distinguish between
threads. (Or at least I believe this would add useful information to the
log).
