reference_wrapper() and operator()()
by Thorsten Ottosen 06 Nov '07

Dear reference wrapper authors, Is there any good reason that boost::reference_wrapper() does not provide a forwarding operator()(), so that we may use it to pass function objects by reference to algorithms? best regards -Thorsten

[date_time] WinCE patch for microsec_time_clock.hpp
by David Deakins 06 Nov '07

06 Nov '07

Just a small patch for the date_time library. WinCE does not supply the GetSystemTimeAsFileTime Win32 method. It does however supply the individual GetSystemTime and SystemTimeToFileTime methods. The config headers already define BOOST_NO_GETSYSTEMTIMEASFILETIME to flag this situation and the patch uses this define to mark when the alternate function calls should be substituted.

[system][asio] Breaking changes procedure?
by Beman Dawes 06 Nov '07

06 Nov '07

At the suggestion of Emil Dotchevski, seconded by Chris Kohlhoff, on my trunk working copy I've moved the system-specific portions of the header <boost/system/error_code.hpp> into new headers. They are named: <boost/system/cygwin_error.hpp> <boost/system/linux_error.hpp> <boost/system/windows_error.hpp> This is a breaking change for asio, and any other boost code that depends on <boost/system/error_code.hpp> containing system-specific enums. New #includes are required for whichever headers apply. This isn't a disruptive change (because the effects are very localized), and normally I'd just coordinate it offline with Chris. But I'd like to shakedown the procedure that should be followed for disruptive breaking changes. Thus this posting to give others a chance to comment. I think the procedure for such breaking changes should be something like: * Create a branch, branches/system. The contents are the entire boost tree. * Apply the Boost.System changes to that branch. * Announce the branch on the list, and encourage any developers affected to update their libraries on the branch. * Once all affected libraries are changed on the branch and passing tests on developer's machines, merge the changes into a working copy of the trunk and do a single commit. * Watch regression tests closely to be sure nothing else broke. Does this sound right? --Beman

[variant] Variants of references, when initialized from temporary objects, should own the temporary object.
by Joachim Kupke 06 Nov '07

06 Nov '07

The following code: #include <iostream> #include "boost/variant.hpp" struct Z { Z(int x) : x(x) { std::cout << "Created a Z with x == " << x << std::endl; } ~Z() { std::cout << "Destroyed a Z with x == " << x << std::endl; } int x; }; void f(boost::variant<const Z&> const& x) { std::cout << boost::get<const Z&>(&x)->x << std::endl; } int main() { int x = 17; std::cout << "A" << std::endl; f(x); std::cout << "B" << std::endl; } produces this output on gcc with boost 1.34.1: A Created a Z with x == 17 Destroyed a Z with x == 17 -11257 B Obviously, x holds a Z reference to a temporary Z, which is destroyed before f() returns. Needless to say, this is in stark contrast with what happens if f had been defined to take a const Z& instead of a boost::variant<const Z&> or a boost::variant<const Z&> const&. Is this a bug? --Joachim

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

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... Jump right in. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - grafikrobot/yahoo

BOOST_NO_ANSI_APIS?
by John Maddock 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.

[1.35] Unmerged changes from 1.34.1
by David Abrahams 05 Nov '07

05 Nov '07

I recently started looking at what changes in my libraries may not have made it into the trunk from 1.34.1. The easiest way was to go to my boost-trunk working copy and svn merge https://svn.boost.org/svn/boost/tags/merged_to_1_34_0/boost https://svn.boost.org/svn/boost/tags/Version_1_34_1/boost What I saw in libraries that weren't my own gave me pause for concern. There are a large number of files with a 'C' or an 'M' next to them. Neither is *necessarily* an indication of a problem, but 'M' (meaning "merged") especially is *likely* to indicate unmerged changes, and 'C' (meaning "conflict") may also indicate unmerged changes. I went and inspected a few of those files and the ones I looked at all seemed suspicious to me. I strongly suggest that all other Boost authors do the command above and inspect "merged (M)," "conflict (C)," and "added (A)" files that they may have touched during the 1.34.x release cycle, or we may find that we've dropped important improvements. One place you should especially check is in your test/ directories, to make sure that you haven't unintentionally dropped any tests between then and now. If your testing is complete and you make sure nothing is dropped, in theory, dropped features and bugfixes won't be able to hide. But there are also documentation changes, so I wouldn't take anything for granted ;-) -- Dave Abrahams Boost Consulting http://www.boost-consulting.com

[Spirit] Using real_parser with user-defined numeric types
by John Maddock 05 Nov '07

05 Nov '07

I'm having a problem using real_parser, I define the parser as: real_parser<some-type> const rr_p; Then use it as: str_p("range")[assign_a(started, false)] && rr_p[assign_a(a)] && rr_p[assign_a(b)] Followed by a list of other alternative commands. When some-type is float/double/long double it all works OK, but as soon as I change some-type to boost::math::ntl::RR then I have two problems: 1) The code doesn't compile: spirit looks for std::pow rather than relying on ADL to find the right overload, I can work around this one for now by importing boost::math::ntl::pow into namespace std. 2) The parser doesn't work, any simple command like "range 0 1" is rejected as invalid. Is there something else I need to do here to enable support for UDT's? Thanks, John.

Embedding copyright and licence information in plot .svg xml documents?
by Paul A Bristow 05 Nov '07

05 Nov '07

I have been study Jake Voytko's GSoC project producing graphs plots in Scalable Vector Graph format (very promising but needs some edges smoothed off). I've been adding a method for the program to add copyright information at least as a comment, " \n" but also as meta data. <meta name="copyright" content="Paul A.

Entire project recompiles when including the multi index container in VS2005
by Avi Revivo 05 Nov '07

05 Nov '07

Hi All, When i include the following header files in one of the header files in my project, even without any other code changes, my project recompiles entirely every build i perform (instead of just modified cpp files) even if no change was done at all. I am working with visual studio 2005, project is compiled without CLR support. #include <boost/multi_index_container.hpp> #include <boost/multi_index/ordered_index.hpp> #include <boost/pool/pool_alloc.hpp> I also include the <boost/multi_index/member.hpp> header however it does not cause the problem, only one of the three above, and seperatly as well. Any ideas? Thanks in advance, Avi Revivo -- View this message in context: http://www.nabble.com/Entire-project-recompiles-when-including-the-multi-in… Sent from the Boost - Dev mailing list archive at Nabble.com.

[asio] patches for Windows CE
by David Deakins 05 Nov '07

05 Nov '07

Here is a set of patches which provides Windows CE support for the Boost.Asio library. Please let me know if anything doesn't make sense or seems out of place. boost/asio/detail/win_thread.hpp: WinCE does not define the process.h header. It also does not supply the _beginthreadex function in its CRT, but this can be simulated with Win32 CreateThread. boost/asio/detail/win_tss_ptr.hpp: WinCE does not supply the TLS_OUT_OF_INDEXES constant. The patch defines this to the appropriate value. boost/asio/detail/socket_ops.hpp: - WinCE does not include the errno variable. - WinCE seems to have the annoying behavior that GetLastError() will report an error code even if the API call was successful. As a result, in the error_wrapper() helper function, it is necessary to check for a non-zero return value (indicating an unsuccessful call) before recording an error code from GetLastError(). - WinCE does not include the ANSI versions of WSAStringToAddress and WSAAddressToString (only the wide-char versions) - WinCE does supply getaddrinfo, freeaddrinfo, and getnameinfo functions. boost/asio/detail/socket_types.hpp: WinCE needs to link to WS2.LIB instead of WS2_32.LIB or MSWSOCK.LIB. boost/asio/detail/win_iocp_io_service_fwd.hpp: WinCE does not support I/O completion ports. boost/asio/ip/detail/socket_option.hpp: For whatever reason, on WinCE the IPPROTO_IP/IP_MULTICAST_TTL option seems to specify a 4-byte int instead of a 1-byte int. boost/asio/socket_base.hpp: boost/asio/ip/unicast.hpp: boost/asio/ip/multicast.hpp: libs/asio/test/socket_base.cpp: libs/asio/test/ip/unicast.cpp: libs/asio/test/ip/multicast.cpp: WinCE does not support the SOL_SOCKET/SO_DEBUG, SOL_SOCKET/SO_DONTROUTE, IPPROTO_IP/IP_TTL, or IPPROTO_IP/IP_MULTICAST_LOOP options. The patches therefore do not define the socket_base::debug, socket_base::do_not_route, unicast::hops or multicast::enable_loopback types for WinCE. It was not clear whether this was the preferred method for handling unsupported options or whether the option types should still be defined and the related tests adjusted to show the options are expected to fail on WinCE. In addition, WinCE does not seem to support changing the receive buffer size with the SO_RCVBUF option, although you can get the receive buffer size with this option. The socket_base::receive_buffer_size tests were adjusted to reflect this behavior. Again, let me know if there are questions or comments.
