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

Genetics library: Volunteers needed
by Andy Thomason 23 Jul '15

23 Jul '15

Hi All, I am recruiting users for the putative genetics library. https://github.com/andy-thomason/genetics We have a few simple examples of gene searching and I am working on a more complete aligner example and some performance improvements to the index data structure. For data, you can obtain the human genome from: ftp://ftp.ensembl.org/pub/release-81/fasta/homo_sapiens/dna/Homo_sapiens.GR… Interesting problems we would like to solve: Given a 20 character sequence with up to six errors, what is the fastest way to list all possibilities other than a brute force search (CRISPR). Can we use JNI to connect the library to Hadoop and other distributed seach systems? Can we construct a database of all known viral genomes including recombination? Can we detect variations in MHC VDJ regions within a single sample? Many other interesting puzzles are there to be found... Andy. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com

Trouble with Boost.Test on ESXi
by William Winder 23 Jul '15

23 Jul '15

I'm using Boost.Test and Boost v1.55 to unit test an application on Windows/Linux/ESXi. The ESXi build is done on a CentOS 5.10 machine, this has been working well for the main application, but the Boost.Test binary hits an assert before running any tests: /tmp # ./MyTests Test setup error: system_error produced by: ::sigaltstack( 0, &sigstk ) != -1: Function not implemented The "Function not implemented" problem has been a recurring problem for me while making my application compatible with ESXi. My basic understanding is that ESXi implements a subset of glibc. I saw a similar issue here: http://comments.gmane.org/gmane.comp.lib.boost.testing/7782 I'm wondering how I can disable this assert and what the repercussions would be. Thanks

gcc 5.1/6.0 warnings with smart_ptr
by Gennadiy Rozental 23 Jul '15

Hi, There are bunch of warnings like these: ../boost/smart_ptr/shared_ptr.hpp:249:65: warning: 'template<class> class std::auto_ptr' is deprecated [-Wdeprecated-declarations] Any chance we can shut these down? Maybe update toolset config? Gennadiy

[boost.test] Assertion/crash
by Philip Bennefall 23 Jul '15

23 Jul '15

Hi all, I am having an issue where boost.test is triggering an assert when I make a BOOST_REQUIRE_EQUAL check. It always gives me the same assert. I am on Windows 7 with Visual C++ 2013, compiling a 32 bit application. This error happens both with boost_1_57_0 and boost_1_58_0. The assert says: Debug Assertion Failed! Program: C:\Windows\system32\MSVCP120D.dll File: C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\xstring Line: 168 Expression: string iterator + offset out of range Here's the stack:

[container] [1.59.0b1] Behavioral (runtime) breakage with flat_xxx + ordered_unique_range + non-default comparator
by Adam Merz 21 Jul '15

21 Jul '15

I've encountered a serious behavioral breakage for code using flat_xxx in conjunction with ordered_unique_range and a non-default comparator in 1.59.0b1. Here is a small repro: #include <initializer_list> #include <algorithm> #include <functional> #include <iterator> #include <iostream> #include <boost/container/flat_set.hpp> int main() { namespace bcont = boost::container; auto const p = [](auto const& desc, auto const& s) { std::cout << desc << ": "; std::copy( s.cbegin(), s.cend(), std::ostream_iterator<int>(std::cout, " ") ); std::cout << '\n'; }; auto const r = {4, 3, 2}; bcont::flat_set<int, std::greater<int>> const s{3, 2, 1}; p("orig set", s); auto s1{s}; s1.insert(r.begin(), r.end()); p("without\tordered_unique_range (expected output)", s1); auto s2{s}; s2.insert(bcont::ordered_unique_range, r.begin(), r.end()); p("with\tordered_unique_range (erroneous output)", s2); } I've worked around this locally by rerouting the ordered_unique_range codepath to the default codepath, but this seems like a showstopper for 1.59.0 as the code's behavior has broken entirely silently.

Python bindings for Boost.Interprocess
by Edison Gustavo Muenz 21 Jul '15

21 Jul '15

Hi all, this is my first e-mail on the list, so please be nice, I’m new here. I have this problem in which I need to communicate between two processes, one written in C++ (it’s actually a .so) and one written in python. They need to share large arrays. I’ve searched on the internet for a way to use shared-memory in python, and the only alternative I found was POSIX IPC for Python <http://semanchuk.com/philip/posix_ipc/> (which looks good, but it is *nix only). Also, I find the Boost.Interprocess library to be a joy to use, it worked for the problem I had, so I wanted to use it. Since I didn’t find python bindings for Boost.Interprocess is it desirable to have this? I started writing some code which uses a tiny part of Boost.Interprocess that is necessary to solve my problem. It is working already. I’m asking here to know what do boost experts think about this idea, if it unreasonable or if other developers already had this need. Feedback would be greatly appreciated. Thanks, Edison Gustavo Muenz

[mpl] Updated fixes on 'master'
by Edward Diener 18 Jul '15

18 Jul '15

A number of fixes in mpl, by Bruno Dutra and Deniz Bahadir, had been tested on 'develop' for quite a long time but had not been merged to 'master' for the upcoming release. The regression tests on 'develop' had shown that the fixes were working properly and I have taken the responsibility of merging them now to 'master' for the upcoming release. I will be checking the 'master' regression tests. If there are any problems I will revert this merge but I am 99.99% certain that the changes are correct, so I take full responsibility for merging. The fixes come from Trac items so I feel that correcting these bugs is important for the upcoming release else I would not have performed the merge and the push to Boost.
