| 252 | * Solaris provides higher throughput, parallelism and scalability than other |
| 253 | * operating systems, at the cost of more fine-grained locking activity. |
| 254 | * This means for example that when a thread is created under Linux, just one |
| 255 | * big lock in glibc is used for all thread setup. Solaris libc uses several |
| 256 | * fine-grained locks and the creator thread resumes its activities as soon |
| 257 | * as possible, leaving for example stack and TLS setup activities to the |
| 258 | * created thread. |
| 259 | * |
| 260 | * This situation confuses Helgrind as it assumes there is some false ordering |
| 261 | * in place between creator and created thread; and therefore many types of |
| 262 | * race conditions in the application would not be reported. To prevent such |
| 263 | * false ordering, command line option --ignore-thread-creation is set to |
| 264 | * 'yes' by default on Solaris. All activity (loads, stores, client requests) |
| 265 | * is therefore ignored during: |
| 266 | * - pthread_create() call in the creator thread [libc.so] |
| 267 | * - thread creation phase (stack and TLS setup) in the created thread [libc.so] |
| 268 | * |
| 269 | * As explained in the comments for _ti_bind_guard(), whenever the runtime |
| 270 | * linker has to perform any activity (such as resolving a symbol), it protects |
| 271 | * its data structures by calling into rt_bind_guard() which in turn invokes |
| 272 | * _ti_bind_guard() in libc. Pointers to _ti_bind_guard() and _ti_bind_clear() |
| 273 | * are passed from libc to runtime linker in _ld_libc() call during libc_init(). |
| 274 | * All activity is also ignored during: |
| 275 | * - runtime dynamic linker work between rt_bind_guard() and rt_bind_clear() |
| 276 | * calls [ld.so] |
| 277 | * |
| 278 | * This also means that Helgrind does not report race conditions in libc (when |
| 279 | * --ignore-thread-creation=yes) and runtime linker itself (unconditionally) |
| 280 | * during these ignored sequences. |

| 589 | /* Behaviour of pthread_join on NPTL: |
| 590 | |
| 591 | Me: |
| 592 | I have a question re the NPTL pthread_join implementation. |
| 593 | |
| 594 | Suppose I am the thread 'stayer'. |
| 595 | |
| 596 | If I call pthread_join(quitter), is it guaranteed that the |
| 597 | thread 'quitter' has really exited before pthread_join returns? |
| 598 | |
| 599 | IOW, is it guaranteed that 'quitter' will not execute any further |
| 600 | instructions after pthread_join returns? |
| 601 | |
| 602 | I believe this is true based on the following analysis of |
| 603 | glibc-2.5 sources. However am not 100% sure and would appreciate |
| 604 | confirmation. |
| 605 | |
| 606 | 'quitter' will be running start_thread() in nptl/pthread_create.c |
| 607 | |
| 608 | The last action of start_thread() is to exit via |
| 609 | __exit_thread_inline(0), which simply does sys_exit |
| 610 | (nptl/pthread_create.c:403) |
| 611 | |
| 612 | 'stayer' meanwhile is waiting for lll_wait_tid (pd->tid) |
| 613 | (call at nptl/pthread_join.c:89) |
| 614 | |
| 615 | As per comment at nptl/sysdeps/unix/sysv/linux/i386/lowlevellock.h:536, |
| 616 | lll_wait_tid will not return until kernel notifies via futex |
| 617 | wakeup that 'quitter' has terminated. |
| 618 | |
| 619 | Hence pthread_join cannot return until 'quitter' really has |
| 620 | completely disappeared. |
| 621 | |
| 622 | Drepper: |
| 623 | > As per comment at nptl/sysdeps/unix/sysv/linux/i386/lowlevellock.h:536, |
| 624 | > lll_wait_tid will not return until kernel notifies via futex |
| 625 | > wakeup that 'quitter' has terminated. |
| 626 | That's the key. The kernel resets the TID field after the thread is |
| 627 | done. No way the joiner can return before the thread is gone. |

| 2963 | /* More comments, 19 Nov 08, based on assessment of qt-4.5.0TP1, |
| 2964 | at least on Unix: |
| 2965 | |
| 2966 | It's apparently only necessary to intercept QMutex, since that is |
| 2967 | not implemented using pthread_mutex_t; instead Qt4 has its own |
| 2968 | implementation based on atomics (to check the non-contended case) |
| 2969 | and pthread_cond_wait (to wait in the contended case). |
| 2970 | |
| 2971 | QReadWriteLock is built on top of QMutex, counters, and a wait |
| 2972 | queue. So we don't need to handle it specially once QMutex |
| 2973 | handling is correct -- presumably the dependencies through QMutex |
| 2974 | are sufficient to avoid any false race reports. On the other hand, |
| 2975 | it is an open question whether too many dependencies are observed |
| 2976 | -- in which case we may miss races (false negatives). I suspect |
| 2977 | this is likely to be the case, unfortunately. |
| 2978 | |
| 2979 | QWaitCondition is built on pthread_cond_t, pthread_mutex_t, QMutex |
| 2980 | and QReadWriteLock. Same compositional-correctness justificiation |
| 2981 | and limitations as fro QReadWriteLock. |
| 2982 | |
| 2983 | Ditto QSemaphore (from cursory examination). |
| 2984 | |
| 2985 | Does it matter that only QMutex is handled directly? Open |
| 2986 | question. From testing with drd/tests/qt4_* and with KDE4 apps, it |
| 2987 | appears that no false errors are reported; however it is not clear |
| 2988 | if this is causing false negatives. |
| 2989 | |
| 2990 | Another problem with Qt4 is thread exiting. Threads are created |
| 2991 | with pthread_create (fine); but they detach and simply exit when |
| 2992 | done. There is no use of pthread_join, and the provided |
| 2993 | wait-for-a-thread-to-exit mechanism (QThread::wait, I believe) |
| 2994 | relies on a system of mutexes and flags. I suspect this also |
| 2995 | causes too many dependencies to appear. Consequently H sometimes |
| 2996 | fails to detect races at exit in some very short-lived racy |
| 2997 | programs, because it appears that a thread can exit _and_ have an |
| 2998 | observed dependency edge back to the main thread (presumably) |
| 2999 | before the main thread reaps the child (that is, calls |
| 3000 | QThread::wait). |
| 3001 | |
| 3002 | This theory is supported by the observation that if all threads are |
| 3003 | made to wait at a pthread_barrier_t immediately before they exit, |
| 3004 | then H's detection of races in such programs becomes reliable; |
| 3005 | without the barrier, it is varies from run to run, depending |
| 3006 | (according to investigation) on whether aforementioned |
| 3007 | exit-before-reaping behaviour happens or not. |
| 3008 | |
| 3009 | Finally, why is it necessary to intercept the QMutex constructors |
| 3010 | and destructors? The constructors are intercepted only as a matter |
| 3011 | of convenience, so H can print accurate "first observed at" |
| 3012 | clauses. However, it is actually necessary to intercept the |
| 3013 | destructors (as it is with pthread_mutex_destroy) in order that |
| 3014 | locks get removed from LAOG when they are destroyed. |
