Looking for Thread Pool Library
by Dean Michael Berris 06 Nov '07

06 Nov '07

Hi Everyone, Has there been any development with regards to a working, portable Boost.Thread based Thread Pool library? Personally I've been using the following sample idiom for achieving what a thread pool is supposed to be accomplishing -- and I'm wondering (aloud) whether there are any existing implementations out there that rely solely on Boost.Thread. Currently, the following code snippet requires Boost.Asio, but I'm not sure if there's something that may be distilled from the recurring pattern below: { using namespace boost::asio; using namespace boost; io_service process_queue; shared_ptr<io_service::work> sentinel(new io_service::work(process_queue)); thread_group processor_threads; for(unsigned int spawn_counter = THREAD_COUNT; spawn_counter > 0; --spawn_counter) processor_threads.create_thread( bind(&io_service::work, &process_queue) ); // add all void nullary functors and post them here process_queue.post(function_object); // once all the work has been queued, remove the sentinel sentinel.reset(); processor_threads.join_all(); } Will something like this be useful as a utility library? Insights, pointers, and suggestions would be very much appreciated. Have a great day everyone! -- Dean Michael C. Berris Software Engineer, Friendster, Inc.

Boost.TypeErasure
by Steven Watanabe 05 Nov '07

05 Nov '07

AMDG After 6+ months I've finally gotten back to this. I'd like to get some feedback on my ideas before I continue. The current version is in the vault. The basic interface is derived from Alexander Nasonov's dynamic_any struct increment : concept_<increment, void(_&)> { template<class T> static void execute(T& t) { ++t; } } any<increment> x(1); increment()(x); assert(type_erasure::any_cast<int>(x) == 1); Note that unlike Boost.Function references will not work. int i; any<increment> x(boost::ref(i)); // NO!! The reason is that if references were allowed it would be to easy to kill yourself. (I've been there. I allowed references at first and then implemented operator+ in terms of operator+=. When the left argument is a reference this means that I made a shallow copy of the reference, called operator += on that, thus violating the expectation that operator+ does not modify its arguments) A function can also return another polymorphic object whose dynamic type is different. template<class R, class P2> struct at : concept<at<R, P2>, R(const P2&, int)> { template<class T> static typename T::value_type execute(const T& t, int i) { return(t[i]); } }; any<at<_1, _> > any_container(std::vector<int>(1, 2)); any<> value(at<_1, _>()(any_container, 0)); assert(type_erasure::any_cast<int>(value) == 2); In this example _ is the placeholder that refers to the current object. The placeholder _1 is used to refer to the return type of at. Since there is a mechanism for handling multiple objects, we can capture multiple objects simultaneously using a tuple: template<class P1, class P2> struct add : concept_<add<P1, P2>, P1(const P1&, const P2&)> { template<class T1, class T2> static T1 execute(const T1& t1, const T2& t2) { return(t1 + t2); } }; int array[] = {...}; type_erasure::tuple<_1, _2, where_<add<_1, _2> > > tuple(&array[0], 0); any<> pointer_to_second_element(add<_1, _2>()(type_erasure::get<0>(tuple), type_erasure::get<1>(tuple)); assert(type_erasure::any_cast<int*>(pointer_to_second_element) == array + 1); The first two arguments to tuple<...> specify which placeholders correspond to those elements. The element 0 will be match _1 and element 1 will match _2. Note that add is not a true multimethod. It's arguments must ultimately come from the same place. i.e. you can apply it as many times as you want since its return type is known to always be the same as its first argument, but you cannot mix another type in e.g. long instead of int. Another thing to note is that it is always okay to discard functions. In the last example the result of calling add itself supports add since it is the same type. I don't care about that so I construct an any<> from it. I haven't shown it here, but any<...> takes up to 10 parameters or an MPL sequence. I can assign one any<> to another which has an arbitrary subset of its functions. One that has both increment and decrement can be assigned to one that supports only increment or to one that supports only decrement. Future Work: I intend to enable boost::ref iff there are no mutating operations for the type. There should be a class for references, so that you can throw away some operations without making a copy. I can implement multimethods if (a) The return type is fixed at compile time and (b) Every type specifies (through a traits template) a list of possible overloads involving it. Functions should be able to handle cases such as template<class P1, class P2> struct some_function : concept_<some_function<P1, P2>, void(const P1&, const P2&)> { //... }; any<some_function<_, std::string> > a1; tuple<_1, _2, where_<some_function<_1, _2> > > t(a1, std::string("The quick brown fox jumps over the lazy dog.")); where some of the arguments are any<>s and others are are of known type. In Christ, Steven Watanabe

[system] error_code_test.cpp does not account for implementation-specific behaviour of strerror()
by Boris Gubenko 05 Nov '07

05 Nov '07

Test error_code_test[_dll] fails on HP-UX and AIX and I'd expect it to fail on Tru64 also (Tru64 results are currently not on the web). The test checks message for error code -1 in both system and posix category and expects it to be "Unknown error". For system category: ec = error_code( -1, system_category ); std::cout << "error_code message for -1 is \"" << ec.message() << "\"\n"; BOOST_CHECK( ec.message().substr( 0, 13) == "Unknown error" ); IIUC, the assumption is that strerror(invalid-error-code) either returns a pointer to a string starting with "Unknown error", which is the case on Linux -- see below, or returns a null pointer in which case libs/system/src/error_code.cpp maps it to "Unknown error" string: const char * c_str = std::strerror( ev ); return std::string( c_str ? c_str : "Unknown error" ); The problem with this assumption is that there is no requirement in the C standard that the message string generated by strerror() for an invalid error code starts with "Unknown error" -- see excerpt from C99 below. For example, on HP-UX, strerror() returns an empty string and on Tru64 it returns "Error -1 occurred." As for the null pointer, strerror() cannot return it -- again, see excerpt from C99 below. X/Open explicitly states that strerror() may signal error by setting errno, but not by returning any particular value: " Upon successful completion, strerror() returns a pointer to the generated message string. On error errno may be set, but no return value is reserved to indicate an error. " It does not mean that error_code.cpp should not check for a null pointer as a precaution against non-conformant implementation of strerror(). In libs/system/test/error_code_test.cpp, the check for the message string corresponding to error code -1 should either be conditionalized for different platforms or removed. Here is conditionalization for system category for HP-UX and Tru64 (I don't have IBM machine at my disposal and cannot figure out conditionalization for AIX): #if defined(__hpux) BOOST_CHECK( *(ec.message().c_str()) == 0 ); #elif defined(__osf__) BOOST_CHECK( ec.message().c_str() == "Error -1 occurred." ); #else BOOST_CHECK( ec.message().substr( 0, 13) == "Unknown error" ); #endif x.c --- #include <stdio.h> #include <string.h> int main() { const char * c_str = strerror( -1 ); printf( "%s\n", c_str ? c_str : "Unknown error" ); } bash-3.00$ uname Linux bash-3.00$ cc x.c && a.out Unknown error 18446744073709551615 bash-3.00$ bash-2.03$ uname HP-UX bash-2.03$ cc x.c && a.out bash-2.03$ cosf.zko.hp.com> uname OSF1 cosf.zko.hp.com> cc x.c && a.out Error -1 occurred. cosf.zko.hp.com> >From C99: --------- 7.21.6.2 The strerror function Synopsis [#1] #include <string.h> char *strerror(int errnum); Description [#2] The strerror function maps the number in errnum to a message string. Typically, the values for errnum come from errno, but strerror shall map any value of type int to a message. [#3] The implementation shall behave as if no library function calls the strerror function. Returns [#4] The strerror function returns a pointer to the string, the contents of which are locale-specific. The array pointed to shall not be modified by the program, but may be overwritten by a subsequent call to the strerror function. Thanks, Boris

Re: [boost] [Boost-testing] [Sandia-PPC-Darwin] Tests failing at Random?

Ping? These failures seem to be appearing at random: last time it was a TR1 test, but now that's passing, but some type traits tests have started failing with no message instead. Anyone any ideas? We really need to get the failures consistent to stand any chance of nailing down a release. Many thanks, John.

question regarding assert and lightweight test
by Robert Ramey 05 Nov '07

05 Nov '07

It seems to me that when I get an assertion in my GCC compilers the test is still being marked as "pass" I'm using lightweight test in the follow way. Does anyone have any suggestions? Robert Ramey int main(int argc, char * argv[]){ boost::serialization::global_lock::get_mutable_instance().lock(); BOOST_TRY{ test_main(argc, argv); } #ifndef BOOST_NO_EXCEPTION_STD_NAMESPACE BOOST_CATCH(const std::exception e){ BOOST_TEST(e.what()); } #endif BOOST_CATCH(...){ BOOST_TEST("failed with uncaught exception:"); } BOOST_CATCH_END boost::serialization::global_lock::get_mutable_instance().unlock(); return boost::report_errors(); }

The big web site push.
by Rene Rivera 05 Nov '07

05 Nov '07

As part of the 1.35.0 release I'm in charge of getting the new web site in shape. The idea is to move to the new independent web site content to ease the release management to only worrying about the libraries themselves. And along the way we also get the new look & feel :-) But since I'm not superman I need help in moving the existing content over to the new structure. Since we are now living in the new Trac age, I created a milestone and tasks for all the content I could immediately find that needs to move <http://svn.boost.org/trac/boost/milestone/Website%201.0>. So if you want to help...

BOOST_NO_ANSI_APIS?
by John Maddock 05 Nov '07

05 Nov '07

When did this one get added? There are no docs, no test case, and the name isn't ideal: maybe BOOST_NO_WINDOWS_ANSI_APIS would be better? Thanks, John.
