include/boost/multiprecision/cpp_int/misc.hpp uses boost::math::gcd (and lcm), but does not include common_factor_rt.hpp.

[variant] Opinion on boost::safe_get<> and default boost::get<> behavior
by Antony Polukhin 18 Dec '15

18 Dec '15

Hi all, I'm in doubt and would like to hear opinions on the following issue. boost::get for boost::variant was not making any compile time checks, resulting in runtime errors where a compile time error must be: boost::variant<int, string> v(100); boost::get<bool>(&v); // returns NULL instead of compile time error boost::get<bool>(v); // throws exception on runtime instead of compile time error Now we have an implementation of compile time checked get in a separate branch at git: boost::variant<int, string> v(100); boost::safe_get<bool>(&v); // compile time error boost::safe_get<bool>(v); // compile time error boost::unsafe_get<bool>(&v); // returns NULL instead of compile time error boost::unsafe_get<bool>(v); // throws exception on runtime instead of compile time error I'm in doubt, what the default behavior of boost::get must be: * safe_get behavior is much closer to Standard Library behavior (just like std::get for tuples) and allows to avoid errors in user code * unsafe_get behavior is same as behavior of old boost::get and won't break user's code if boost::get is used in some generic contexs What's your opinion? -- Best regards, Antony Polukhin

[WG21 mailing] N4453 Resumable expressions
by Niall Douglas 15 Oct '15

15 Oct '15

I'm finding Chris' paper on resumable expressions instead of compiler magic created resumable functions awfully compelling: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4453.pdf I essentially proposed the same with my functionally composed constexpr basic_future design some months ago. Would anyone else like to comment on this library based instead of compiler based resumable execution? I'm not against some compiler support for resumable execution, but I am finding the await based proposal highly problematic, and Chris does an excellent job in summarising my own thoughts on what's wrong with it.

[context] msvc /SAFESEH
by Jeff Flinn 12 Aug '15

12 Aug '15

I need to build my application with /SAFESEH which uses boost coroutine which uses context. I'm getting the following link errors: 1>libboost_context-vc100-mt-gd-1_53.lib(jump_i386_ms_pe_masm.obj) : error LNK2026: module unsafe for SAFESEH image. 1>libboost_context-vc100-mt-gd-1_53.lib(make_i386_ms_pe_masm.obj) : error LNK2026: module unsafe for SAFESEH image. I've built boost static libs with the same MSVC vesion and options (sans /SAFESEH as it's not a compile/lib option) Compiler/linker versions: Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.40219.01 for 80x86 Microsoft (R) Incremental Linker Version 10.00.40219.01 Has anyone run into this and resolved the error? Any insight is appreciated. Thanks, Jeff

Test Runner Update to vc14.0 - CTP 6
by Tom Kent 23 Jul '15

23 Jul '15

Just a heads up, I have just updated the test runner teeks99-08f-win2012R2-64on64 from vc14.0 - CTP 4 to vc14.0 - CTP 6. The change should show up in the next run of that runner in a few hours. I think some people were waiting to see if MS was fixing some things, so I thought I'd send a message letting people know these results would be available. Tom

Serializing shared_ptr fails on .template
by Jared McIntyre 15 Jul '15

15 Jul '15

I've run into an issue where VS 2013, and likely earlier versions, fail to serialize a shared_ptr because Visual Studio is choking on the use of ar.template get_helper in load() to remove ambiguity. The issue appears to replicate previous bug report here: https://svn.boost.org/trac/boost/ticket/10727 That report didn't post an example, so instead of adding a new bug, I've posted example code to that existing report. VS 2013 Boost 1.57 Jared McIntyre

Fwd: [SORT] Parallel Algorithms
by Francisco José Tapia 01 Jul '15

01 Jul '15

Hi Steven I had been revising and testing spreadsort, and the results are impressive. I have prepared the benchmarks and include spreadsort. Now the numbers are extracted from a file generated with a random number generator. In a few days I will put all in a git repository for a easy access As I had seen, you use boost::sort for to invoke to spreadsort. If you use this name, which name use for to invoke introsort? I think a good idea can be call the algorithms by their name. If we do this we have the next algorithm list : - spreadsort - spreadsort_integer - spreadsort_float - spreadsort_string - introsort - parallel_introsort - smart_merge_sort - parallel_stable_sort - sample_sort I think it's a simple and easy to understand, because with the name sort, many people think about an algorithm as introsort ( general , not specific for several data types) and not stable. What's your opinion ?

[coroutine2] add to testing
by Oliver Kowalke 21 Jun '15

21 Jun '15

Hi, I'm uncertain if boost.coroutine2 (C++11-only) will be part to the 1.58 release - a git-submodule exists but not at the list for the regression tests (I've opened a pull-request to boostorg/boost). Could you tell me the status of boost.coroutine2?! thx, Oliver
