bjam bug? Strange permission
by Neal Becker 02 Aug '12

02 Aug '12

While tracking down strange directory permissions, I noticed this: find . -name .hg -prune -o -type d $ \! -perm 755 -and \! -perm 775 $ -ls 17315044 4 drwxrw-r-- 3 nbecker nbecker 4096 Aug 2 08:41 ./bin.v2 I assume that dir was created by bjam during the test build, for some reason with strange mode.

Announce: Boost 1.50 installer for 32-bit Windows now available
by John Wiegley 01 Aug '12

01 Aug '12

With apologies to the community for not finding the time to release Windows installers for 1.48 and 1.49, we now have an installer for 1.50 available for immediate download: http://www.boostpro.com/download The version installs 32-bit libraries and/or DLLs for the following compilers: Visual C++ 8.0 (Visual Studio 2005) Visual C++ 9.0 (Visual Studio 2008) Visual C++ 10.0 (Visual Studio 2010) We are dropping support for Visual C++ 7.1 as of this time, unless someone wishes to contract us to bring it back. Also, although I have prepared a 64-bit installer, I have not yet found a solution for integrating it with the existing installer. If anyone with NSIS scripting experience would be willing to assist me, we'd be happy to provide a free installer which installs both 32-bit and 64-bit Boost libraries for applicable Windows platforms. Enjoy! -- John Wiegley BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

Jurko, are these reformatting changes really necessary? It sounds like it will just make it harder to update Python port when we get back to it when semester starts in September. Thanks,

If you want some kind of key/value feature testing, it doesn't belong under the regular version flag. Please revert this.

interest in generic cyclic visitor
by Jan Herrmann 01 Aug '12

01 Aug '12

Hello, I have an implementation of generic cyclic visitor. It is available at https://github.com/janherrmann/visitor . With my implementation it is possible to create non-member, non-friend templates which behave like virtual functions. Additionally it can be used as a base for multimethod implementation. Moreover it can be used to build a extensible type information system. All test cases compile with msvc-10.0 and gcc-mingw-4.6.2. Is there need for such a library? Jan Herrmann

Review Request: Endian
by David Stone 01 Aug '12

01 Aug '12

A few months back I posted a proposal for an endian conversion library: http://lists.boost.org/Archives/boost/2012/04/191931.php I believe my library is now in a finished state, and I would like to have it considered for inclusion into Boost. A zip file containing everything can be found here: https://bitbucket.org/davidstone/endian/get/tip.zip or you can just browse the repository here: https://bitbucket.org/davidstone/endian/ The only file that users need to be concerned with is endian.hpp. endian.cpp contains performance + correctness tests, and example.cpp is a very short example program on how to use the library that opens up a file, reads in a number that was written in big-endian format, and prints it to the user's screen in host format. There is no special compiling / linking instructions (people who wish to test the program can simply compile endian.cpp). Included is a SCons script that allows easy compilation with gcc or clang with many warnings + optimizations turned on. My programs all compile cleanly at very high warning levels in these compilers because I know many users compile their own projects at such a setting, and I don't want a library file causing noise. I included the documentation in index.html, but I'm not quite sure on how to correctly format things.

My take on an allocate_shared_array and make_shared_array implementation
by Glen Fernandes 31 Jul '12

31 Jul '12

Hi all, I've desired an allocate_shared_array for a while (and, looking at some existing threads about the topic, it seems others have also). Recently, while working with a code base that accepted both shared_ptr<T> and shared_array<T> for a sequence of T elements, I decided to write both (for shared_ptr<T> since shared_array<T> does not support allocators). The code for both my make_array<T> and allocate_array<T> initial implementation can be found at: https://github.com/glenfe/glenfern/tree/master/glenfern I was wondering if there is any desire for these (after necessary tweaking, refinement, and testing) to become part of Boost. I'm not certain how useful they are in their current form for people using shared_array<T> that can't switch to shared_ptr<T>. Is there any desire to update shared_array<T> so that it supports custom allocators? In that event, my implementation can then easily be applied to shared_array<T> as well. Alternatively, are there any plans to provide a separate smart pointer type for an array with allocator support? Cheers, Glen

[block_ptr] Update
by Phil Bouchard 31 Jul '12

31 Jul '12

Hi, It's been more than a year since a completed the block_ptr and it seems as if more recent library are being reviewed first. This would suggest the FIFO of the schedule is not followed. I was just wondering since at the same time the reviewing of block_ptr is cost / beneficial. Regards, -Phil Author of: http://www.fornux.com/ http://www.finitetheory.com/
