[Range] Proposal: a sub-maintainer of Boost.Range
by Michel Morin 05 Jan '13

05 Jan '13

Dear Neil, Dear Nate, First I'd like to say thank you for your library, Neil. It is a very useful library and it's great fun to writing codes with range adaptors. Boost.Range is one of the most important Boost libraries that are not yet added to the Standard. I know that Neil has made an effort to make time for developing the library, but recently making time for development seems difficult. And there are several open tickets of trivial bugs (e.g. #5603, #6110). Considering this situation, I'd like to make a proposal about Boost.Range: ** Adding a sub-maintainer to Boost.Range ** This reduces author's maintenance burden and also helps more stable development of the library. I recommend Nathan Ridge as a sub-maintainer of Boost.Range. His knowledge, experiences and contribution to Boost are great. If both of Neil and Nate accept the proposal, and if Nate needs some support for the start-up, I'll try my best to support him. I also believe that Jeff will also support him ;) Neil, what do you think about this proposal? I would appreciate and respect any of your reply. Yours sincerely, Michel

Hi, I would like to apply the following patch to trunk and release branch to avoid the Boost.Thread breaking changes. * [@http://svn.boost.org/trac/boost/ticket/6229 #6229] Rename the unique_future to future following the c++11. * [@http://svn.boost.org/trac/boost/ticket/6266 #6266] Breaking change: thread destructor should call terminate if joinable. * [@http://svn.boost.org/trac/boost/ticket/6269 #6269] Breaking change: thread move assignment should call terminate if joinable. This will let us the time to discuss the best way to manage with this breaking changes. Is someone against this late change?

[atomic] building with --layout=system, mingw, bug #7482
by Tim Blechmann 04 Jan '13

04 Jan '13

hi, i need some help with resolving issue #7482: for some reason it seems to build a static libboost_atomic, although it has to be a shared library. could someone with more insights in this platform have a look, what's going wrong (and why the library is static)? unfortunately i neither have access to mingw, nor am i too familiar with the boost build infrastructure ... thanks, tim

Release managers: Boost.Thread breaking changes in 1.53
by Vicente J. Botet Escriba 04 Jan '13

04 Jan '13

Hi, there has been some threads about the following Boost.Thread breaking change in release 1.53. "Breaking changes when BOOST_THREAD_VERSION==3 (Default value since Boost 1.53): There are some new features which share the same interface but with different behavior. These breaking features are provided by default when BOOST_THREAD_VERSION is 3, but the user can however choose the version 2 behavior by defining the corresponding macro. As for the deprecated features, these broken features will be only available until boost 1.55. * [@http://svn.boost.org/trac/boost/ticket/6229 #6229] Rename the unique_future to future following the c++11. * [@http://svn.boost.org/trac/boost/ticket/6266 #6266] Breaking change: thread destructor should call terminate if joinable. * [@http://svn.boost.org/trac/boost/ticket/6269 #6269] Breaking change: thread move assignment should call terminate if joinable. " I would like to request advise from the release managers and of course the Boost community. Should I rollback the default to BOOST_THREAD_VERSION==3 for 1.53 and let the time to discuss the best way to manage with these breaking changes? Best, Vicente
