[thread] A simply static initializeable mutex
by Roland Schwarz 01 Nov '06

01 Nov '06

Triggered by the question how to do static initialization of a mutex, I tried to write one that is. The most basic initialization that wil be performed by the compiler, is zero initialization of static (POD) objects. This kind of initialization will take place before any other initializations. Consequently the mutex is initialized by its mere declaration. However this does come at a price: 1) Since the mutex has no ctor, one must not forget to initialize it when using it as a member of some containing object. But this is the same as with other POD's. 2) Altough the mutex is copyable this does not make any sense. The identifying property of a mutex is its memory address. Trying to lock a copied mutex will get you in trouble. It is not possible to protect against such usage since we have no ctor that could be declared private. On the other side you can make a object that contains a mutex copyable by simply reinitializing it to zero, which is not possible with the current mutex, since copying is strictly prohibited. I appended to this mail my first attempt to implement such a mutex . The code is commented and a pingpong test is included as example. So far this is only for windows. I would be very interested to get feedback about this idea. Roland // Copyright (C) 2006 Roland Schwarz // // Distributed under the Boost Software License, Version 1.0.

(See accompanying // file LICENSE_1_0.txt or copy at http://www.boost.org/LICENSE_1_0.txt) // This is an experimental implementation of a mutex // that is of type POD. I.e. typedef scoped_lock* volatile mutex; // An unowned mutex has value 0. Consequently there is no need // for dynamic initialization, which solves the static // initialization problem. // Furthermore it also is not necessary to e.g. // mutex mx = 0; because static objects are zero initialized // by default, before any other initializations take place. // As such, availability of this mutex type makes a once // function unnecessary. // // Memory and resource management is fully automatic. I.e. // no leaks under normal usage. (In the basic version no cleanup // in the atexit handler is required.) The implementation needs // availability of some atomic primitives and semaphores // from the operating system. // // The required data structures are all within a scoped_lock // object. Destruction of the lock also frees up the resources. // // Typical usage: // mutex mx; // void foo() // { // scoped_lock lk(mx); // ... // } // // How does it work: // The scoped_lock object contains a doubly linked list. // The mutex is pointing to the head of this list. When // the mutex is zero the list ist empty and the mutex // unowned. // Locking the mutex means putting a list entry to the // head of the list. This is done atomically. Concurrent // requests are queued up, and each put on a separate // semaphore. This scheme already could be used by itself // (see e.g mcs-locks in win32 pthreads), however it // imposes a FIFO scheduling behaviour. // This implementation instead uses this queue only during // the build up, and then hands over the waiting to a // shared semaphore, to let the system scheduler wake up // the threads. The doubly linked list makes it possible // to remove list items from the list in an arbitrary // order. // // Performance: // I did only a minimalistic "pingpong" test, which showed // comparable performance to the current boost::mutex. // I expect that the performance can be improved, if the // semaphore objects are not completeley destroyed after // temporary use, but instead put in a lock free container // for later reuse. This however would raise the requirement // to destroy them during atexit. // // Missing parts: // I havent tried yet if it is possible to also provide // try and timed lock variants. // Altough I tried to take care of the necessary memory // barriers for SMP, I am not convinced yet that I got it // straight in this first attempt. // Also I have not yet been able to prove the correctness of // the algorithm. #include "mutex.hpp" // The operating system dependent part #include <windows.h> #include <limits.h> #include <cassert> template<class T> inline T* atomic_swap_full(T* volatile * p, T* a) { return (T*)InterlockedExchangePointer(p,a); } template<class T> inline T* atomic_load_full(T* volatile *p) { return (T*)InterlockedExchangeAdd((LPLONG)p,0); } template<class T> inline bool atomic_bool_compare_and_swap_full(T* volatile *p, T* c, T* s) { return (c == (T*)InterlockedCompareExchange((LPLONG)p,(LONG)s,(LONG)c)); } template<class T> inline T* atomic_compare_and_swap_full(T* volatile *p, T* c, T* s) { return (T*)InterlockedCompareExchange((LPLONG)p,(LONG)s,(LONG)c); } class semaphore { public: // The open and close functions could be extended // to put the closed items onto a lock free // container instead. static semaphore* open(int count = 0) { return new semaphore(count); } static void close(semaphore* sema) { delete sema; } void post() { ReleaseSemaphore(sem, 1, NULL); } void wait() { WaitForSingleObject(sem, INFINITE); } private: semaphore(int count) { sem = CreateSemaphore(NULL, count, LONG_MAX, NULL); } ~semaphore() { CloseHandle(sem); } HANDLE sem; }; // The following should be operating system independent scoped_lock::scoped_lock(mutex& m, bool initially_locked) : is_locked(false) { pmutex = &m; if (initially_locked) lock(); } scoped_lock::~scoped_lock() { if (is_locked) unlock(); } void scoped_lock::lock() { assert(!is_locked); next_lock = 0; pred_lock = 0; sema_flag = 0; next_flag = 0; scoped_lock* pred = atomic_swap_full(pmutex, this); if (0 != pred) { pred_lock = pred; pred->next_lock = this; wait_for(&pred->sema_flag); // pass on the shared semaphore sema = pred->sema; set(&sema_flag); set(&pred->next_flag); sema->wait(); } else { // create the shared semaphore sema = semaphore::open(); set(&sema_flag); } is_locked = true; } void scoped_lock::unlock() { assert(is_locked); scoped_lock* n = atomic_load_full(&next_lock); if (0 == n) { if (0 != pred_lock) { pred_lock->next_lock = 0; pred_lock->next_flag = 0; } if (atomic_bool_compare_and_swap_full(pmutex,this,pred_lock)) { if (0 == pred_lock) { // We have no predecessor and are the last // to hold this semaphore.

Sorry, I missed that one. I've corrected now in CVS, with covering test. Thanks for spotting again. Cheers Dan Send instant messages to your online friends http://uk.messenger.yahoo.com

[proto] interface changes
by Eric Niebler 01 Nov '06

01 Nov '06

To all those currently using the proto expression template toolkit at boost/xpressive/proto (all 2 of you, you know who you are), this is a heads up that the code has been rewritten, and the interfaces changed considerably. The changes have been committed to HEAD. The goals of the rewrite were many, but to sum up, the new code has a simpler, more uniform interface, integrates better with Fusion, and seamlessly supports ET nodes stored by value or reference. As a perk, xpressive now compiles 2x faster with vc7.1, and 25% faster with vc8. (No significant change with gcc.) The people most interested would be the Spirit people. The changes are specifically to make proto a better platform upon which to build Spirit-2. Now that I have an interface I can live with, I'm more inclined to write docs, and I will. The old proto v1 code from 1.34 now lives at boost/xpressive/proto/v1_ in the boost::proto1 namespace. -- Eric Niebler Boost Consulting www.boost-consulting.com

Bug? The at_impl had been completed omitted. I've fixed this in the cvs, and added covering tests. Thanks for spotting this.

Simulating log{10}(2)
by Daryle Walker 31 Oct '06

31 Oct '06

Our code that deals with determining how many characters are needed to express an integer in decimal form, based on the number of bits, use a conversion factor like: #digits <= 2 + #bits * log{10}(2) where "log{10}(2)" is the logarithm of 2 for base 10. This can be calculated from "ln(2) / ln(10)", where "ln" is the natural logarithm function. Since the conversion factor is used in compile-time integer contexts, the constant is expressed as an integer multiply followed by an integer divide. The decimal expansion of the constant is approximately 0.30102999566.... Our code uses cut-off versions of that expansion for the constant: static int const digits10 = 2 + digits * 301 / 1000; I've also seen "30103 / 100000" being used. Couldn't there be better approximate fractions to use? Based on various web calculators, like Google's and "Contfrac" at <http://wims.unice.fr/wims/wims.cgi?session=B75AF6A950.2&+lang=en&+module=to ol%2Fnumber%2Fcontfrac.en>, I've found a continued fraction representation of the constant. An irrational number has an infinitely long c.f. expansion, but the convergents off that expansion are usually the best rational approximations of an irrational value. Let's compare expansions: 1. ln 2 / ln 10 = [0; 3, 3, 9, 2, 2, 4, 6, 2, 1, 1, 3, 1, 18, 1, 6, 1,...] 2. 0.301 = [0; 3, 3, 9, 1, 2, 3] 3. 0.30103 = [0; 3, 3, 9, 2, 2, 4, 5, 1, 1, 1, 2] where [a0; a1, a2,...] = a0 + 1/(a1 + 1/(a2 + ...)). The common approximation 0.301 differs from the actual expansion at a4 = 2. The convergent there is 59/196. The absolute differences between those values and the actual value are: |log{10}(2) - 0.301| = 2.9995664e-5 |log{10}(2) - 59/196| = 9.58750072e-6 The convergent is 3.1 times closer to the actual value than the common approximation. Using 0.30103 versus the convergent 4004/13301 at the point of differing a7 = 6 gives the convergent an improvement factor of 2.1. The convergents have smaller numerators and denominators than their common approximations, making them easier to calculate without worry of overflow. Conversely, if you know that you have more leeway in multiplications, then using higher convergent fractions instead of the decimal expansion are a better bet. -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com

[GIL] Asking for help for vc2003 compiler bug
by Christian Henning 31 Oct '06

31 Oct '06

Hi there, taking the latest GIL source from their site is exposing a tedious compiler bug with VC2003. I have been trying to find an easy wokaround but failed. It fails in channel.hpp when trying to define specializations for channel_min_value() and channel_max_value. Here is the code: template <typename T> typename channel_traits<T>::value_type inline channel_min_value() { return std::numeric_limits<typename channel_traits<T>::value_type>::min(); } template <typename T> typename channel_traits<T>::value_type inline channel_max_value() { return std::numeric_limits<typename channel_traits<T>::value_type>::max(); } template<> inline bits8 channel_min_value<bits8>() { return 0; } template<> inline bits8 channel_max_value<bits8>() { return 255; } template<> inline bits16 channel_min_value<bits16>() { return 0; } template<> inline bits16 channel_max_value<bits16>() { return 32768; } template<> inline bits32f channel_min_value<bits32f>() { return 0.0f; } template<> inline bits32f channel_max_value<bits32f>() { return 1.0f; } Here is the compiler error messages: c:\gil\gil\core\channel.hpp(95) : error C2785: 'channel_traits<T>::value_type gil::channel_min_value(void)' and 'gil::bits8 gil::channel_min_value(void)' have different return types c:\gil\gil\core\channel.hpp(90) : see declaration of 'gil::channel_min_value' c:\gil\gil\core\channel.hpp(95) : see declaration of 'gil::channel_min_value' c:\gil\gil\core\channel.hpp(95) : error C2912: explicit specialization; 'gil::bits8 gil::channel_min_value<gil::bits8>(void)' is not a specialization of a function template c:\gil\gil\core\channel.hpp(95) : fatal error C1903: unable to recover from previous error(s); stopping compilation I have been trying to find a workaround reading some news groups entry. But all I could find are conformations that this is a bug and that VC2005 is compiling. Not very helpful. Does anyone here at boost know a workaround? I have realized that this request is offtopic. Please, ignore when feeling that my request is inappropriate. Thanks, Christian
