Fastest Data-structure maybe from STL or Boost ..!!
by Rahul Mathur 15 Oct '13

15 Oct '13

All, I wish to record 1000 real time data which need to be in sorted order. I used STL MAP which sorts using KEYS and than sorted the value using STL VECTOR, the complete scenario give me almost 6ms of time analysis. The TARGET is to achieve almost 1.5 - 2.0 ms. Also, once this data structure is completely filled I want to delete the first data and replace it with the new data. Can I have the fastest data structure (STL or BOOST) techniques for the same. ~ Thanks!!

[release/atomic] request permission to merge 86144
by Tim Blechmann 15 Oct '13

15 Oct '13

i'd like to merge r86144 into release. it is not exactly a bugfix, but it enables double-width cas support for msvc, which is rather important for many lock-free algorithms to be lockfree with this toolchain (including some configurations of stack/queue of boost.lockfree). thnx, tim

Requesting svn access
by Mathias Gaunard 14 Oct '13

14 Oct '13

Hi, There are a couple of warnings generated by unmaintained libraries that I'd like to fix. (In particular https://svn.boost.org/trac/boost/ticket/9115) Would it be possible to have write access so that I can commit these to trunk and then to release?

[config] Patch for clang.hpp to support clang in Windows using VC++ RTL
by Edward Diener 14 Oct '13

14 Oct '13

Once Boost 1.55 is out the doors can I apply the attached patch for clang when _MSC_VER is defined ? Unfortunately clang in this situation does not currently support the C++11 types char16_t or char32_t ( there is a bug report for this ), and this means trying to compile Boost libraries like type_traits without this patch yields many errors. I would have used the BOOST_WORKAROUND macro but clang does not support a value which gives a single number for the compiler version so I felt that drumming up multiple BOOST_WORKAROUNDs using major/minor/patch version numbers was too much of a hack to bother about.

Support for BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION
by Joaquin M Lopez Munoz 14 Oct '13

I understand there's been some discussion about dropping support for compliers with BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION defined. Has some final decision been made about this? Thank you, Joaquín M López Muñoz Telefónica Digital

Permission to proceed?
by Stephen Kelly 14 Oct '13

14 Oct '13

Hello, Now that the beta has been out for a while, I'd like to proceed with my clean-up commits in trunk. I'd like to commit the patch in http://thread.gmane.org/gmane.comp.lib.boost.devel/244392/focus=244397 immediately and then proceed to remove the resulting dead code. Can I go ahead and do that? I assume that does not have any effect on the release branch. Thanks, Steve.
