[regression runner] Preference libstdc++ vs. libc++
by Tom Kent 09 Mar '17

09 Mar '17

I have a bunch of linux regression runners that are executing clang runs of the boost regression suite (clang 3.0 - 4.0), currently these are all using the default, GCC libstdc++. Is there an interest from developers to see these runs with libc++? The basic options: 1) Convert all compatible clang builds to libc++, don't mess with libstdc++ & clang. 2) Duplicate all the clang builds to build each version with both (acknowledging that will add nearly 1/3 to the already large ~125 linux runs). 3) Change most of the runs, but keep a few token libstdc++ & clang runs, with the latest compiler version (what c++ standard c++14? c++1z?). 4) Just add a few token libc++ runs, with the latest compiler version (what c++ standard c++14? c++1z?). 5) Don't add libc++. For background (you can respond to one of the above preferences without reading on), there are two machines constantly running linux builds (in addition to the two windows ones) that I manage. One I consider the "full" suite of compilers. It runs clang 3.0 - 4.0 and gcc 4.4 - 6. For the oldest and latest releas (gcc 4.4, gcc 6, clang 3.0, clang 3.9), I run all the supported standard configs I could find (c++98, c++0x, gnu98, gnu0x -- c++03, c++11, c++14, c++1z and their gnu equivalents). I also do runs with optimization and warnings cranked, against the latest standard config e.g. "-std=c++1z -O2". For all the compiler versions that aren't on the endcaps, I just run a single config with whatever was the latest standard config for that compiler (e.g. gcc-4.8 with c++1y). This is all repeated for develop and master for a total of about 100 different configurations. The machine I consider the "fast results" machine is configured with only four runs, one each for the latest release of gcc and clang with the latest supported standard config (currently gcc-6 1z and clang-3.9 1z), for both master and develop. The goal here is that for any change checked in, the author will have feedback on its success against something modern and relevant within just a few hours. As a backup to the "fast results" machine, I also run those four regression modern runs, interspersed with the rest of the configs every dozen or so runs, bringing the total number of runs on the "full" machine up to around 125, which takes about a week for the machine to get through all the configurations. You can see more details about all of this on the github page where I keep my regression build scripts: https://github.com/teeks99/boost-build/tree/master/Regression The actual confgs run by the "full": https://github.com/teeks99/boost-build/blob/master/ Regression/teeks99-02/machine_vars.json The docker builds for all these machine configurations are kept at: https://github.com/teeks99/boost-build/tree/master/Docker And can be pulled from the docker hub with e.g. `docker pull teeks99/boost-build:clang-3.9` If you've read this far, I'd be happy for any other opinions from developers who use the test matrix. Is it worth keeping all those compilers in the middle? Do we need to test the latest compilers with all the different standard configs (03, 11, 14, 1z + gnu equivalents)? Thanks, Tom

[safe numerics] comment
by Robert Ramey 09 Mar '17

09 Mar '17

I'm re-posting Vicente's message which apparently got lost in a server issue so we can respond to it. Robert Ramey Hi, let me start with some comments and questions. I was wondering if the requirements of Numeric don't need some kind of conversions between other numeric types. https://htmlpreview.github.io/?https://raw.githubusercontent.com/robertrame… T(u) T{u} How can you implement the conversion from safe<U> to T if you can not convert from U to T? We have implicit conversion from T to Safe and from Safe to T template<class T> constexpr /*explicit*/ safe_base(const T & t); template< class R, typename std::enable_if< !boost::numeric::is_safe<R>::value, int >::type = 0 > constexpr operator R () const; constexpr operator Stored () const; I believed that the conversion from Safe to T needed to be explicit. Having implicit conversion in both directions is suspect. Why the explicit conversion between safe<T> and safe<U> are not allowed when T and U are not the same? IMO, safe_base<T> is either not trivial default constructible and we check the validity of 0, if we don't check it, we should declare it =default. The current definition doesn't adds nothing and makes the type a non-POD and non trivial_default_constructible, which forbids its use on binary messages. constexpr explicit safe_base() { // this permits creating of invalid instances. This is inline // with C++ built-in but violates the premises of the whole library // choice are: // do nothing - violates premise of he library that all safe objects // are valid // initialize to valid value - violates C++ behavior of types. // add "initialized" flag. Preserves fixes the above, but doubles // "overhead" // still pending on this. } I'll suggest to use constexpr safe_base() = default; BTW, why the default constructor is declared explicit? As you say, could we talk of safe<short> when we can have one uninitialized? I believe this needs to appear clearly on the documentation if not already in. Has safe<const T> a sense? Integer<T> are not traits as there is a compiler error when T is not an integer :( template <class T> class Integer : public Numeric<T> { // integer types must have the corresponding numeric trait. static_assert( std::numeric_limits<T>::is_integer, "Fails to fulfill requirements for an integer type" ); }; The same for Numeric. Have you considered to define traits (usable with SFINAE)? I don't see a concept SafeNumeric. Have you considerd it? BTW, these concept classes check only for a single requirement. Shouldn't you specialize numeric_limits lowest()? Have you considered to define basic algorithms managing with the valid conversion between Numeric with the different policies, as Lawrence Crowl is proposing for the standard? http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0103r1.html http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0105r1.html I find weird the way you are including the files #include "concept/integer.hpp" #include "concept/exception_policy.hpp" #include "concept/promotion_policy.hpp" #include "safe_common.hpp" #include "exception_policies.hpp" #include "boost/concept/assert.hpp" I believed we used to inlcude boost files using <> and the absolute path. Is this a good practice? Does it allows the compiler to perform better? Best, Vicente

[gsoc17] Project1: Static map: Can I implement the competency test in g++-7?
by Vic Luo 07 Mar '17

07 Mar '17

Hi, I'm Zheng Luo, a third-year undergraduate from Shanghai Jiaotong University who have special interest in C++ programming(especially for templates). This is my second year of applying Google Summer of Code and I'm willing to contribute to Static Map project mentioned on SoC2017 page. Previously I worked for a company as a C++ intern for months on Chromium-related projects where I gained some experience about C++ in industry. And my question is, am I allowed to implement the competency test of static_map in g++-7? I have just implemented my own version of static_map which supports the following operations: constexpr StaticMap<int, const char *, 3> m(make_pair(2, "abc"), make_pair(4, "def"), make_pair(6, "ghi")); if (!m[4]) abort(); const char *foo = m[2]; return 0; which is compiled into assembly as: main: xorl %eax, %eax ret under g++-7 with -std=c++1z -O3 So I was wondering did I pass the test? Thanks, -- --------------------------------- Vic Luo Shanghai Jiaotong University Key fingerprint 0x98809ca08bf5662a

[gsoc17]Getting started with Project 2 in Boost.Geometry:R-tree serialization
by Ruoyun Jing 07 Mar '17

07 Mar '17

Hi Everyone: My name is Ruoyun Jing, I am an undergraduate student in Northwest University(China) of Software Engineering.Although i am a girl,i really love coding and algorithms!!! I've coded many algorithms problems with C++ and Python,and got Bronze Metal in ACMICPC Asia Shenyang Regional contest. GSoC is really a precious chance for me to get in touch with open source software. After reading all the organizations and their projects, I'm pretty interested in R-tree serialization in Boost.Geometry. Despite my lack of project experience,i will try my best to learn ,code and communicate with mentor!!! Looking forward from you.:) Thank. -- Northwest University of China Software Engineering jingry0321(a)gmail.com <jingry0321(a)163.com>

[gsoc17]Getting interests in uBLAS
by Ruoyun Jing 06 Mar '17

06 Mar '17

Hi, I am Ruoyun, I'm back again.:) In these few days, I'm getting start with boost by [link](https://github.com/boostorg/boost/wiki/Getting-Started), and got something wrong with developing/checking out a particular branch that in Ubuntu, I can not find the file called"modular-boost",but when I tried to "cd libs/geometry",it went run. When I tried to contact the devs of geometry in gitter, IRC, and email, there is only a reply for me. So I'm pretty interested in math about any aspects, because during my life of algorithm competition, I was good at algorithms in geometry, number theory, linear algebra and etc. I am really want to contact with mentor more frequently to learn more knowledge and provide more contributions to boost. I'm also interested in uBLAS and willing to learn knowledge about that !!! Looking forward from you! Thanks.
