[python] extracting a string and a one-length list containing a string
by Allan Johns 13 Mar '11

13 Mar '11

Hello, Given a boost::python object, how can I the difference between that object containing a string, or a sequence of length 1 whos zeroeth element is a string? Ie: "foo" --vs-- ["foo"] bp::extract<std::string> succeeds in both cases. I can use PySequence_Check to test for a sequence, and then I can test the length of the zeroeth element - if >1 then it's ["foo"] - but then I still can't disambiguate ["X"]. tia! Allan

[range] Should the result of irange satisfy the BidirectionalRangeConcept?
by Vicente Botet 13 Mar '11

13 Mar '11

Hi, I'm trying to define an enum_range and I based my implementation on the one from irange. While writing my test I started just by checking that my enum_range satisfied the RandomAccessRangeConcept requirements and there were some errors with BidirectionalRangeConcept. I replaced by the result type of the irange function and the errors appear also there. It seems that there is an issue concerning the category tags ..\..\../boost/concept_check.hpp:212:13: error: conversion from 'boost::detail::iterator_category_with_traversal<std::input_iterator_tag, boost::random_access_traversal_tag>' to non-scalar type 'std::bidirectional_iterator_tag' requested Am I missing something? Best, Vicente == Test == #include <boost/range/concepts.hpp> #include <boost/range/irange.hpp> using namespace boost; BOOST_CONCEPT_ASSERT(( BidirectionalRangeConcept < iterator_range<

[range] compile error with extra ; with some compilers and options

Hi, The extra ";" in has_range_iterator.hpp results in a compiler error on some compilers with -pedantic option. Could this patch be applied on trunk?

[Track] What's up with track
by Robert Ramey 13 Mar '11

13 Mar '11

I log into track system with my name (ramey). The I select issues and select "my Issues". It seems that now the list includes all the issues previously closed so the count is 254 going back to 2004. The actual number should be on the order of 15. Can someone fix this or tell me what to do differently? Robert Ramey

[docs][boostbook] FOP 1.0 is broken
by Ronald Garcia 13 Mar '11

13 Mar '11

Howdy, Just an FYI. Apache FOP 1.0 has a bug that causes it to crash with an exception when building boost PDF documentation. This bug has been fixed in the FOP repository, so nightly builds of fop do not exhibit it.

Javascript in Boost.Serialization docs
by Bryce Lelbach 13 Mar '11

13 Mar '11

As per http://www.boost.org/development/requirements.html#Documentation, ECMAScript/JavaScript is not acceptable in Boost documentation (explained in http://www.boost.org/development/requirements.html#JavaScript= ). Boost.Serialization's sidebar uses JavaScript to expand/close tabs. Is this policy no longer valid? If so, can someone update the aforementioned refere= nces? Otherwise, can the JS from the Boost.Serialization docs be removed? -- Bryce Lelbach aka wash boost-spirit.com px.cct.lsu.edu

[PATCH] [config] Disable threads on Carbon, since MPTasks aren't supported
by Joshua Juran 12 Mar '11

12 Mar '11

Disable threads on Carbon, since MPTasks aren't supported Boost.Thread hasn't supported MPTasks since 1.33.1. Prevent the definition of BOOST_HAS_THREADS in the non-pthreads case so spinlocks compile (which are needed for smart pointers).
