[trac] where is david_abrahams?
by Eric Niebler 11 Jan '14

11 Jan '14

Dave is still listed as the primary maintainer of several libraries, but Trac won't let me assign a new bug to him. "david_abrahams" isn't one of the choices in the Owner drop down. Where'd he go? -- Eric Niebler Boost.org http://www.boost.org

[multi_index][ann] Boost.MultiIndex 1.56 preview: major update with new hashed index implementation
by Joaquín Mª López Muñoz 11 Jan '14

11 Jan '14

Hi, Those interested can already download the preview of Boost.MultiIndex as it'll be shipped in Boost 1.56: https://github.com/boostorg/multi_index/archive/master.zip Full release notes can be read at https://rawgithub.com/boostorg/multi_index/master/doc/release_notes.html#bo… The most important change is a complete reimplementation of the internals of hashed indices, so that erasure of elements is constant-time regardless of the level of occupancy of the internal bucket array (previously, performance degraded as the bucket was being depleted.) A full description of the new data structure as compared with other popular implementations of unordered associative containers is given at: http://bannalia.blogspot.com/2013/10/implementation-of-c-unordered.html http://bannalia.blogspot.com/2013/10/implementation-of-c-unordered_25.html Along with some performance results: http://bannalia.blogspot.com/2013/11/measuring-insertion-times-for-c.html http://bannalia.blogspot.com/2013/11/measuring-insertion-times-for-c_16.html http://bannalia.blogspot.com/2013/11/measuring-erasure-times-for-c-unordere… http://bannalia.blogspot.com/2013/11/measuring-lookup-times-for-c-unordered… The new data structure has been thoroughly tested but some pre-shipping feedback is always welcome, so if you test this please report back.

Fumbling with modular Boost and GIT
by Paul A. Bristow 10 Jan '14

10 Jan '14

I have recently been fumbling with Modular Boost to do some routine maintenance and update of documentation on Boost.Math, with generally most unhappy results. Although this is partly from my general modest familiarity with GIT, I feel that the documentation of the process of doing things is woefully thin. There are far too many vital details assumed or unsaid. I'm posting this in the hope that someone will produce a fully documented and illustrated blow-by-blow (preferably using Tortoise GIT and including its displays) description of how to work cooperatively on the develop branch, and a specific library development sub-branch. This should cover (at least) getting changes to headers in /boost and /libs made by others, making a change to a header file, making a change to tests, testing it using an IDE, and making a change to an example (containing some embedded Quickbook) in and IDE and running it, and to changing Quickbook files in the /library/doc folder, and finally pushing. And now, for a change, I'm off for a little quiet alligator wrestling ;-) Paul --- Paul A. Bristow, Prizet Farmhouse, Kendal LA8 8AB UK +44 1539 561830 07714330204 pbristow(a)hetp.u-net.com

Hi Richard, Thanks for your reviews. Based on them, You be interested in help me improve the library? You seem to have great knowledge on the side windows and your help would be great! What are the best practices to follow? In your opinion how do you think the API should be encapsulated? Thanks a lot

[Program Options] fix for #6797 breaks compilation
by Jürgen Hunold 09 Jan '14

09 Jan '14

Hi Volodya, the fix for #6797 in 4ae33ce15e5b6345e6eefa19466fdf7cd28a7bbd breaks compilation if Boost.ProgramOptions on msvc-11.0 and -12.0. See full error log with msvc-11.0 attached. It seems that the export macros changes the template evaluation somehow, so msvc now needs "decrement" and "advance" member. The short error is: E:\dev\devel\boost\boost/iterator/iterator_facade.hpp(402) : error C2039: 'decrement' : is not a member of 'boost::program_options::detail::common_config_file_iterator' E:\dev\devel\boost\boost/iterator/iterator_facade.hpp(420) : error C2039: 'advance' : is not a member of 'boost::program_options::detail::common_config_file_iterator' I'm not sure how to implement at least empty stubs or if this can be otherwise worked around.

Once accepted, when does a library undergo further review?
by legalize+jeeves＠mail.xmission.com 08 Jan '14

08 Jan '14

[Please do not mail me a copy of your followup] Boost has a good peer review process for accepting a new library. However, once a library has been accepted, it doesn't seem to go through any more peer review. Is the maintainer just trusted to embrace the spirit of Boost's peer review acceptance process for all further changes to a library? -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!

Hi All, I want to share one simple article about proposed Boost.Application! In the current version of Boost.Application, its officially supports 2 types of application: --------------------------------------------------- * Common Application [This kind of application is a usual Interactive Terminal application] * Server Application [This kind of application generates a Service (Windows), or a background process/Daemon (Unix)] In this article I try to show how user can extend the Boost.Application to support new application mode/type: --------------------------------------------------- * A Simple 'Apache Content Generator Module' http://www.codeproject.com/Articles/695937/Creating-a-New-Application-Mode Others Boost.Application Resources: --------------------------------------------------- [code] https://github.com/retf/Boost.Application [docs] http://www.dokfile.com/appbeta4/docs/libs/application/doc/html/index.html Please, let me know what you think about Boost.Application! -- Renato

[git] Some headers are executable
by Andrey Semashev 08 Jan '14

08 Jan '14

Hi, I've just checked out git and ran b2 headers and noticed that some headers have executable attribute. For example: $ find boost -executable -type f boost/pointee.hpp boost/assign.hpp boost/graph/vf2_sub_graph_iso.hpp boost/indirect_reference.hpp boost/parameter.hpp boost/detail/indirect_traits.hpp boost/detail/is_xxx.hpp boost/range.hpp This was not the case with svn. Is this the result of the transition? Can this be fixed?
