[Modularization] Breaking dependecy Range -> Algorithm
by Vicente J. Botet Escriba 06 Jun '14

06 Jun '14

Range depends on Algorithm due to these files /algorithm/ <http://www.pdimov.com/tmp/report-6d1f271/algorithm.html> |<boost/algorithm/string/config.hpp>| * from |<boost/range/detail/collection_traits.hpp>| * from |<boost/range/detail/collection_traits_detail.hpp>| |<boost/algorithm/string/yes_no_type.hpp>| * from |<boost/range/detail/collection_traits_detail.hpp>| * | boost/algorithm/string/yes_no_type.hpp could be moved to TypeTraits|| boost/algorithm/string/config.hpp| could be moved to Config Best, Vicente

GitHub is slow

For the couple past days I'm seeing problems working with GitHub. I can't complete the full update of Boost repository multiple times in a row: ... Fetching submodule libs/regex ssh: connect to host github.com port 22: Connection timed out fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. Fetching submodule libs/scope_exit Fetching submodule libs/serialization ssh: connect to host github.com port 22: Connection timed out fatal: Could not read from remote repository.

I'm also seeing occasional timeouts in web interface. I've seen these problems from two different places, so it's not my local connection. Is anyone seeing this too?

Boost.Pimpl upcoming formal review (June 15 - June 24)
by Glen Fernandes 05 Jun '14

05 Jun '14

The formal review period of Boost.Pimpl by Vladimir Batov is scheduled to begin later this month, on June 15th, and will conclude on June 24th, and we welcome your participation. Vladimir's library provides a mechanism for implementing this popular, and still very relevant, idiom. To borrow his words from the documentation: [quote] In the domain of commercial large-scale software development the following design principles come to the fore: - component-based, modular and API-centered design, - separation of concerns, - implementation hiding, - minimization of compilation and component dependencies, - consistent and recognizable deployment and implementation patterns, multi-platform support. The Pimpl idiom can help great deal achieving those goals. It is a simple yet robust programming technique to minimize coupling via the separation of public interface and private implementation and then implementation hiding. [/quote] Please feel encouraged to browse the source code, documentation, and tests, before the review commences. Any feedback you have prior to the review period is also very appreciated. Source: https://github.com/yet-another-user/boost.pimpl/ Documentation: http://yet-another-user.github.io/boost.pimpl/ Download: https://github.com/yet-another-user/boost.pimpl/archive/master.zip If you would like to submit a review earlier, please provide your thoughts on the following topics: - What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the library? As well as information on the following questions: - Did you try to use the library? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? - Are you knowledgeable about the problem domain? And most importantly: - Do you think the library should be accepted as a Boost library? Best, Glen

[quickbook] Thank you Daniel James
by Rene Rivera 05 Jun '14

05 Jun '14

After being very surprised that I could build Predef documentation without errors by onyl updating to the latest develop version of Quickbook I had to thank Daniel James. Thank Daniel for the continued work on Quickbook. It's made my life much, much, easier! -- -- Rene Rivera -- Grafik - Don't Assume Anything -- Robot Dreams - http://robot-dreams.net -- rrivera/acm.org (msn) - grafikrobot/aim,yahoo,skype,efnet,gmail

Moving utility/declval.hpp to type_traits
by Peter Dimov 05 Jun '14

05 Jun '14

I was going to move utility/declval.hpp to type_traits, but type_traits has many unmerged changes. Since the contents of declval.hpp are currently the same in master and develop, replaying its history on top of type_traits:master and type_traits:develop should not affect any later merges, but still, I always prefer to do this when master and develop are identical, so thought I'd ask first. John?

[config] intel-linux with -fno-rtti doesn't set BOOST_NO_RTTI...
by Peter Dimov 05 Jun '14

05 Jun '14

... and BOOST_NO_TYPEID. I can see in the config_info output that __RTTI (without the option) is 1, so maybe the check belongs in common_edg.hpp.

[core] Move underlying_type to type_traits?
by Andrey Semashev 04 Jun '14

04 Jun '14

While documenting and cleaning up scoped_enum.hpp I factored out the underlying_type trait to a separate header. Mostly, because I didn't want to #include <type_traits> in scoped_enum.hpp. boost::underlying_type should be equivalent to std::underlying_type, except that it also supports emulated scoped enums. Perhaps boost/core/underlying_type.hpp should be moved to Boost.TypeTraits?

Looking for git help for Boost releases
by Marshall Clow 04 Jun '14

04 Jun '14

I’m trying to figure out tooling for making boost releases. One of the missing pieces that we had in SVN was “svn export”, which let you check out a particular branch/revision to a local folder, w/o any of the SVN infrastructure (such as .svn folders). It also let you set the line endings of the files, so I could make a release with Windows line endings on a non-windows computer. The command that I used was: svn export --non-interactive --native-eol XXX -r YYY, https://svn.boost.org/svn/boost/branches/release ZZZ where: XXX was line ending that I wanted (either CRLF for windows or LF for unix) YYY was the revision that I was interested in (usually HEAD) ZZZ was the destination for the export How can I do something like this for git? I’ve looked at “git archive”, and that’s something like what I want, but it doesn’t handle sub-projects. There are a few scripts around that claim to do “git archive over sub-projects”, but I haven’t found one that works with our set up, and none of them let you modify the line endings for (some of) the files as part of the process. Any ideas? Suggestions? Pointers? Thanks in advance. — Marshall

[Predef] Splitting a version number into components
by Arindam Mukherjee 04 Jun '14

04 Jun '14

Given some vendor version number, is there any macro in Predef to split it into major, minor and patch components? I noticed the macros BOOST_PREDEF_MAKE_* macros. What do these macros help achieve which BOOST_VERSION cannot? Thanks, Arindam
