[SVN] Mime types on check in
by Robert Ramey 16 Aug '07

16 Aug '07

I'm having problems checking in a couple of file types: *.vcproj // text xml for VC projects *.sln // text xml for VC solutions These don't appear in my local SVN configuration. And the pre-commit script is complaining about them. Could this be fixed please? Robert Ramey

pool allocator question
by Steve Kettle 15 Aug '07

15 Aug '07

I have a question about the memory pool allocation that boost implements. Suppose we do the following: std::vector<int, boost::pool_allocator<int> > v; for (int i = 0; i < 10; ++i) v.push_back(-1); And the std::vector<int> is implemented so that it starts out with reserved space of 1 and doubles space every time. So At the end of the above loop v will have size 10 and reserved size 16. Does the boost allocator mean that there will memory arrays lieing around of size 1,2,4,8 that can be reused ? Eg if you do this: std::vector<int, boost::pool_allocator<int> > v; for (int i = 0; i < 10; ++i) v.push_back(-1); std::vector<int, boost::pool_allocator<int> > v2; for (int i = 0; i < 8; ++i) v2.push_back(-1); There will be no system call needed to get more memory - v2 will just reuse the memory in the pool_allocator<int> ? Thanks. Steve. --------------------------------- Take the Internet to Go: Yahoo!Go puts the Internet in your pocket: mail, news, photos & more.

[rfc] proposal to add enable_if_defined to Boost.Utility
by Stjepan Rajko 15 Aug '07

15 Aug '07

Hello, I have found the following little snippet of code quite useful (it is modeled closely after enable_if, but it enables if the given type has been defined, kind of like enable_if + HAS_XXX but simpler and more general). I am curious whether you think this functionality is useful in general, whether the implementation is OK, and whether you think it might be useful to add it to the Utility library (if the functionality is not somewhere else in boost already): // if T is a valid type enable_if_defined result is Result, otherwise specialization failure template<typename T, typename Result=void> struct enable_if_defined { typedef Result type; }; struct void_; // if we need to test for multiple types, we can use all_of template<typename T0=void_, typename T1=void_, typename T2=void_, typename T3=void_, typename T4=void_, typename T5=void_> struct all_of { }; Some examples of how I've been using it: /// Example 1: specialize a template if the type has a trait: template<typename T, typename Enable=void> struct producer_category_of { }; // if T has the producer_category trait, use it to specify producer_category_of template<typename T> struct producer_category_of<T, typename detail::enable_if_defined<typename T::producer_category >::type > { typedef typename T::producer_category type; }; /// Example 2: specialize a type if the type has a couple of metafunctions defined for it: template<typename T, typename Enable=void> struct is_producer : public boost::false_type {}; // If T has both producer_category_of and producer_type_of specified, it is_producer template<typename T> struct is_producer<T, typename detail::enable_if_defined<detail::all_of< typename producer_category_of<T>::type, typename produced_type_of<T>::type > >::type > : public boost::true_type {}; There is some overlap between the proposed enable_if_defined with the existing enable_if in combination with mpl's HAS_XXX. Advantages of enable_if_defined: * unlike enable_if+HAS_XXX, there is no need to define a separate metafunction for each trait to be tested * enable_if_defined can be used to test any type expression that will work with SFINAE Disadvantages of enable_if_defined: * there is no corresponding disable_if_defined * can't be directly used with MPL - if you need a boolean metafunction corresponding to an enable_if_defined, then you do need to define one. * probably not compatible with as many compilers as enable_if+HAS_XXX Any feedback welcome - if this is not a good approach please tell me why so I can stop using it. Thanks, Stjepan

boost/functional/detail/hash_float.hpp: patch to quiet gcc warning
by Caleb Epstein 15 Aug '07

15 Aug '07

The for loop in float_hash_impl in <boost/functional/detail/hash_float.hpp> generates a warning from gcc when instantiated with T = float. Changing the < to != quiets the warning. Here's the warning: /pkg/boost/include/boost/functional/detail/hash_float.hpp: In function 'size_t boost::hash_detail::float_hash_ impl(T) [with T = float]': /pkg/boost/include/boost/functional/detail/hash_float.hpp:136: instantiated from 'size_t boost::hash_detail: :float_hash_value(T) [with T = float]' /pkg/boost/include/boost/functional/hash/hash.hpp:307: instantiated from here /pkg/boost/include/boost/functional/detail/hash_float.hpp:109: warning: comparison of unsigned expression < 0 is always false Here's the patch: diff -ur boost-1.35.0-svn38670/include/boost/functional/detail/hash_fl oat.hpp boost/include/boost/functional/detail/hash_float.hpp --- boost-1.35.0-svn38670/include/boost/functional/detail/hash_float.hpp 2007-08-15 07:52:45.838953000 -0400 +++ boost/include/boost/functional/detail/hash_float.hpp 2007-08-14 12:59:02.358904000 -0400 @@ -106,7 +106,7 @@ boost::static_log2<limits<T>::radix>::value - 1) / limits<std::size_t>::digits; - for(std::size_t i = 0; i < length; ++i) + for(std::size_t i = 0; i != length; ++i) { v = boost::hash_detail::call_ldexp(v, limits<std::size_t>::digits); std::size_t part = static_cast<std::size_t>(v); -- Caleb Epstein

Looking for Time Series reviews
by John Phillips 15 Aug '07

15 Aug '07

To date there have been no reviews of the time series library posted to the developer or user lists. Is this a bad time for a review, or is no one interested enough in this library to put in the time to submit one? If you feel the library isn't interesting or useful enough, please post a note to the list so I can see that opinion. If you are struggling for time to do the review, please post at least a short opinion, and if a few days extension will make a difference we can investigate that possibility. However, the next review begins on August 13, so time for this is somewhat limited. John Phillips Review Manager

Inquiry of standardization status of boost::format
by manphiz 15 Aug '07

15 Aug '07

Due to the limitation of gettext usage with standard iostream, there's a proposal to improve the case in glibmm's string implementation [1], whose goals resemble boost::format very much. There's a thought that if boost::format is going to be standardized, then it's better to adopt the boost syntax and ease switching to standard in the future. So is this happening? How's the status?

spirit bug/change in 1.34
by Christian Holmquist 15 Aug '07

15 Aug '07

Hello, Our own regressions with parsers built on spirit fails with boost 1.34.0(haven't tried 1.34.1 yet). Before 1.34, the following worked. #include <boost/spirit/core.hpp> void main() { using namespace boost::spirit; const char *text = "1 "; assert(parse(text, int_p, space_p).full); } Now, it seems that the trailing space after the '1' in text is not consumed by the space_p, and parse does not return a full parse in parse_info. Is this the intentional behaviour and we should update our rules to take care of any trailing white space? Best regards, Christian

[result_of] void by default
by shunsuke 14 Aug '07

14 Aug '07

Hi, I hope this is the last question about result_of. I want to know the reason why result_of<F()>::type returns void by default instead of an incomplete type like template<typename F> struct error_this_is_not_a_nullary_function; which could make error message more readable. I found the one reason: The function composition. result_of<F(result_of<G()>::type)>::type is always well-formed unless result_of<A_NonNullary_Function()> is specialized for some reason. Was result_of designed with a view to the function composition? Regards, -- Shunsuke Sogame

[time_series] Review
by Steven Watanabe 14 Aug '07

14 Aug '07

AMDG I still need to think a bit more before I vote but here are all the comments I have so far: In the Series Interface section in the user's guide shouldn't series-type( A0 const &, A2 const &, ... ); be prefaced by template<class A0, class A1, ...> ? "It may seem odd that even the unit series have a value parameter..." Wouldn't it be better to use a traits template to determine what "one" should be and require that this template be specialized? If there is no unambiguous unit value for a type then isn't it a little odd to use a unit series? Discretization | Equivalent To daily | mpl::int_<1> ... These are guaranteed not to be just typedefs I hope? You should state that the runtime discretization compatibility check is an assertion as opposed to throwing an exception. You also need to specify exactly what it means for discretizations to be the same--that the discretizations must be the same type (Otherwise I might be inclined to consider 1l and 1 equal) and that operator== must be defined ( Else I would likely try struct my_discretization {}; typedef sparse_series<double, my_discretization> series_type; ). Shouldn't ordered_inserter use the named parameters start, stop, and value? The promotion rules are complicated is there a metafunction that computes the result types or should I just use Boost.Typeof? Is this specialization missing in traits/conversion.hpp template<typename From, typename To> struct is_storage_convertible<scaled_storage_tag<From>, To> : is_storage_convertible<From, To> {}; serialize should use nvp so that it will work with xml archives. The following fails to compile because serialization is not defined for daily: #include <iostream> #include <boost/time_series/sparse_series.hpp> #include <boost/archive/text_oarchive.hpp> typedef boost::time_series::sparse_series<double, boost::time_series::daily> series_1; int main() { series_1 s1; boost::archive::text_oarchive ar(std::cout); ar << s1; } The comparison operators for time_series_base are defined in time_series_facade. Shouldn't they be in utility/time_series_facade.hpp? time_series_facade line 256: template<typename Left, typename Right> bool operator !=(time_series_base<Left> const &left, time_series_base<Right> const &right) { return ! operator ==(left.cast(), right.cast()); } This rules out a member operator==. Since you're explicitly downcasting and invoking ADL I would expect any definition of operator== to work. time_series_facade.hpp line 280 this->sout_ << " value = " << value << ", " << " offset = " << start << ", " << " end offset = " << stop << '\n'; value shouldn't have a space before it should it? time_series_facade.hpp line 395 template<typename Derived, typename Storage, typename Discretization> struct tag<time_series::time_series_facade<Derived, Storage, Discretization> > { typedef time_series_tag type; }; Should this be typedef tag<Derived>::type type;? numeric/numeric.hpp line 3 /// Defined the mathematical operator s on time series -> /// Defines the mathematical operator's on time series The description of series_stl_iterator in the reference has no direct indication of what kind of iterator it is. Is a time series required to inherit from time_series_base? If it is then this should be specified in the concepts somehow. If not then the reference for time_series_base should not say that it is a base for all time_series. The TimeSeries concepts section lists only dense series as models. Should it list the other time_series's to? The RangeRunStorage concept page has an empty See Also section. This is probably a boostbook issue but there are lots of empty namespaces in the reference section. ordered_inserter.hpp line 205 range_run_storage::set_at(this->inserter_, std::make_pair(offset, endoff), value); should this use run_type instead of std::pair? I strongly dislike ordered_inserter. Its name indicates to me that it adds elements to a time_series--not at all that it deletes all pre-existing elements. I would expect it to overwrite the old elements only where a new element is specified. This program compiles but fails at runtime. It should fail at compile time. #include <boost/time_series/sparse_series.hpp> #include <boost/time_series/ordered_inserter.hpp> using namespace boost::time_series; typedef sparse_series<double, int, double> series_1; int main() { series_1 s1; make_ordered_inserter(s1)(1.0, 0.0, 1.0).commit(); } time_series_facade.hpp line 262 #ifdef _MSC_VER BOOST_MSVC? Other places too. Something somewhere is suppressing "warning C4244: 'initializing' : conversion from 'double' to 'int', possible loss of data" and not restoring it but I'm not sure whether it's in your library yet. My IDE (MSVC 8) keeps freezing--Has anyone else noticed this? (It could be caused by code in trunk, too) I ran a quick test of sparse_series<quantity<SI::length> > and it worked fine. What does discretization mean for floating point offsets? For sparse/dense series with floating point offsets indexing doesn't make sense. Probably it should be made illegal somehow.... I would partly agree with Stjepan about the dichotomy between sparse/dense series and piecewise constant series. As I see it there are three cases a) sparse/dense and floating point b) piecewise constant and floating point c) integral Because of the limits on integers piecewise constant series and point series behave the same way for them. Multiplication makes no sense for point series. Likewise adjacent_difference, integrate, piecewise_sample, piecewise_surface_sample, and index. In Christ, Steven Watanabe
