[IdentityType] Const omission undocumented.
by Mostafa 03 Dec '13

03 Dec '13

#include <boost/utility/identity_type.hpp> #include <utility> int main() { BOOST_IDENTITY_TYPE(( std::pair<int,int> const )) x; // This compiles, so the const qualification in the // above macro parameter is ignored. x = std::make_pair(0,1); return 0; } The omission of const qualification in BOOST_IDENTITY_TYPE types is undocumented. This omission maybe deduced from the documented implementation, but, as noted, that is not part of the library api and is … [View More]

[swap] std::swap should be pulled in from <utility> in C++11
by Joaquin M Lopez Munoz 03 Dec '13

03 Dec '13

Hi, boost/utility/swap.hpp #includes <algorithm> to bring std::swap in, which is OK for C++03 but not so in C++11: std::swap has been moved to <utility> as explained in [diff.cpp03.library]. Should I create a ticket? Best regards, Joaquín M López Muñoz Telefónica Digital

[conversion] GitHub boostorg repos now open for regular use
by Beman Dawes 02 Dec '13

02 Dec '13

Please be cautious at first, and report any problems. It is probably a bit surer to follow the full clone instructions at https://svn.boost.org/trac/boost/wiki/TryModBoost rather than trying to make use of a previous clone. Also note that those instructions have been corrected several times, the most recent correction just a minute ago. We will be setting up write permissions, but that may take a day or so. Thanks, --Beman

[conversion] Progress Report
by Beman Dawes 02 Dec '13

02 Dec '13

We are very close to being able to go live with boostorg at GitHub. * Following the instructions at https://svn.boost.org/trac/boost/wiki/TryModBoost, the "master" branch seems ready to go. * A couple of libraries on the "develop" branch may still have end-of-line issues. If so, those should be resolved first thing in the morning. So please be patient one more day, and then we should be able to get to work using git and modular boost. --Beman

circular buffer patch
by Serge A. 02 Dec '13

02 Dec '13

It appears that the circular_buffer no longer has a maintainer. I have a patch that fixes a problem introduced in the latest versions of the circular buffer that it can not correctly work with a custom memory allocator. The patch is provided here: https://svn.boost.org/trac/boost/ticket/9334 The former maintainer suggested to submit a request to this list, so that the patch is included in the daily build and the next release. Thanks! Serge
