Removing auto_ptr/etc. from Boost
by Stephan T. Lavavej 25 Mar '15

25 Mar '15

Hi Boost devs, I need your help to get rid of auto_ptr forever. I want to implement C++17's N4190 "Removing auto_ptr, random_shuffle(), And Old <functional> Stuff", although it's going to take a while. In VC 2015, the removal will be opt-in (requested via a macro; I've already checked this in). My plan is for the removal to be opt-out in the version after that, and unconditional in the version after that. To achieve the opt-in removal, I've already eliminated the STL's internal dependencies on this stuff (nothing derives from unary_function/binary_function anymore, and shuffle() isn't directly implemented with random_shuffle() anymore). To prepare for the future of opt-out removal, I've also been removing usage from the compiler and other stuff. However, Boost is used in our tests in a number of places. What I'd like to ask is for Boost to begin removing its usage of this stuff (unconditionally or for VC 2015+, your pick). According to my understanding, only unary_function/binary_function and auto_ptr are used extensively by Boost, with the other stuff being used rarely or not at all. Thanks, Stephan T. Lavavej Senior Developer - Visual C++ Libraries

[iterator] Bug #7526
by Claas 25 Mar '15

25 Mar '15

Hi! I was wondering, how the iterator developers intend to proceed with ticket #7526 (https://svn.boost.org/trac/boost/ticket/7526) Two fixes are available and seemingly just wait to be applied. One fix has been available for two years, and a more sophisticated (probably preferable) fix has been submitted 9 month ago. Has this simply been forgotten or are there any reasons, not to apply one of the available patches ?. Since I require the requested functionality, I would like to press the issue. If more support is required to fix this, please let me know. Since two years I have had to patch each version of boost manually to deploy this fix, which is a little frustrating. So I would gladly contribute, if this is required. Any update on the issue would be appreciated. Regards Claas

[TypeSort] Automatic type sorting
by costis glynos 25 Mar '15

25 Mar '15

Hello,Is there any interest in a library which automatically sorts types from smallest to largest at compile time?The benefit would be the automatic Data Structure Alignment and potential improvement in performance.Foo<int,bool,Custom16ByteType,char,double,short> foo_1; //normal Foo<int,bool,Custom16ByteType,char,double,short> foo_2; //using the TypeSort output: size of foo_1 = 48 size of foo_2 = 32 Kind Regards, Constantinos

Boost 1_58_0_rc1 is available for testing
by Marshall Clow 25 Mar '15

25 Mar '15

Release candidate files for 1.58.0 beta 1 are available at http://boost.cowic.de/rc/ As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy. This helps ensure the candidates build OK before we push them out to SourceForge. IMPORTANT NOTE: There is a bug with the build scripts; you have to specify the address-mode and architecture to b2. I used: ./b2 address-model=64 architecture=x86 to test this. The files (and associated md5s) are: MD5 (boost_1_58_0_b1_rc1.7z) = 302c7dfc917227843d24beed33ccc99c MD5 (boost_1_58_0_b1_rc1.tar.bz2) = d7d030e85bf5534a328c108c62a7fb0e MD5 (boost_1_58_0_b1_rc1.tar.gz) = ec90cd23bdc99c5eaf88245ea94a28e0 MD5 (boost_1_58_0_b1_rc1.zip) = dc8379fb95c84fe2fca53a4b2c96da23 Thanks! -- The release managers

[Hana] Informal review request
by Louis Dionne 24 Mar '15

24 Mar '15

Dear Boost, As some may be aware of, I am currently working on a metaprogramming library called Hana, with the intention of proposing it for inclusion in Boost. The purpose of that library is to act as a toolbox for expressing computations on both types (like the MPL) and heterogeneous values (like Fusion). The library is built around C++14 idioms and implementation techniques to maximize expressiveness and performance. I am now requesting feedback from the community, with the intention of asking for a formal review in the next months. A similar review was asked for in last August. The library has undergone several modifications since then, both to address issues raised during the review and for general improvement. Here are some issues that were raised during the review and addressed: - Usage of names and terms unknown to C++ programmers: Efforts were made to make this better, and several functions were renamed (`fmap` is now `transform`). When possible, the documentation also uses terms more familiar to C++ programmers, like concept instead of "type class". - The order of the arguments to some algorithms was unfortunate for C++. It was consistent with Haskell, but it turned out to be cumbersome in C++. This is changed in most places. - Inability to easily implement individual algorithms: This is fixed, and algorithms are now standalone structures using tag-dispatching, almost exactly as in Fusion. - Lack of a good introductory tutorial: A lot of work has gone into improving both the tutorial and the reference documentation. - Lack of support for mainstream compilers: The library is now almost fully functional with Clang 3.5. A GCC 4.9 port with reduced functionality is also underway on the `redux` branch. The library is available at [1] and the documentation at [2]. Comments should be directed to this mailing list, while bugs and other similar problems should be directed to the GitHub issue tracker. Please participate, especially if you have interest and/or experience in metaprogramming; after all, you represent the target audience for Hana. Thank you, Louis Dionne [1]: https://github.com/ldionne/hana [2]: http://ldionne.github.io/hana/

boost regex recursive quesion
by 温西波 24 Mar '15

24 Mar '15

This is my first time to using maillist I'm learning to use boost::regex for a month , a few days ago I found a problem( maybe is my mistake ?) I construct a simple recursive regular expression: a(?0)? This regex contains a recursive call (?0). It should match a string with any arbitrary length filled with 'a' characters. regex_match only returns true for "a" and "aa", but failed to match "aaa" and any string longer than three characters. Why? I try it on boost 1.45 and 1.57 , both get same result . I had sent this question on stackoverflow , but had not get a answer now . Is there any flag should be used with regex_match to use recursive call ? Thank you .

BOOST_SYMBOL_VISIBLE
by Robert Ramey 23 Mar '15

23 Mar '15

I'm trying to get my MAC OS (Yosemite) to build the boost serialization library and I've having a problem. In a couple of tests, the program throws some exceptions. When this occurs I get a message something like "terminate called after throwing an instance of 'boost::archive::archive_exception'". I'm quite sure that I used to be able to do this without problem - as of a couple of months ago. I recently "upgraded" to Yosemite. My gcc-4.8.1 version I'm getting from HPC website. In the course of trying to figure this out, I've come upon boost documentation which explains BOOST_SYMBOL_VISIBLE which was new to me. It suggests that my code which looks like class archive_exception : public virtual std::exception { ... could be creating a problem. due to deriving from some other class which might be defined a runtime shared library. So I replaced it with: class BOOST_SYMBOL_VISIBLE archive_exception : public virtual std::exception { ... and I also tried class BOOST_SYMBOL_VISIBLE archive_exception : public virtual std::exception { ... This doesn't change anything so it looks like I'm barking up the wrong tree. Is there anyone here who might want to shed some light on this?

Multiple-pattern string search algorithms
by meghana madhyastha 23 Mar '15

23 Mar '15

Hi all ! I noticed that Boost's algorithm module does not include multiple pattern string searching algorithms such as the Rabin Karp algorithm and Aho-Corasick algorithm. I think these algorithms are very useful and should be implemented in the library. If no one is currently working on them, I am willing to implement them. Please let me know your opinion. Regards, Meghana

I'm starting to write a caution to go in the release, and will make that point. A new test, "floating_point_test", has been added to the endian test suite. It will focus on interoperability. (I know that you are talking about users testing their application needs, but I want to test Boost.Endian to be able to warn users of areas where there are known issues.) > It should obviously be between all possible combinations of processor hardware types.

Application for GSOC 2015
by Alexandru Hulea 23 Mar '15

23 Mar '15

Hello, My name is Alexandru Hulea and I am an undergraduate student at University POLITEHNICA of Bucharest. I am in the third year at The Faculty of Automatic Control and Computers. My email can be found at [1]. About availability, I think 40 hours / week will be enough, but I will work more if the complexity of the project will require that. The only factors which will affect my availability will be the exams which are scheduled in the first 2 weeks of June. About my educational background, I took some courses related to the projects I apply including C Programming, Data Structures, OOP, Algorithms, Parallel and Distributed Algorithms. I participated in 2 summer schools working on a project in Android and on another project in OpenGL with C++. My favourite programming language is C++. I have 3 years experience in C/C++ and I am interested in scientific work like developing libraries of C++. I like to solve algorithms exercises, to find tricky optimisations for ACM exercises or other programming contests and recently I discover the wonderful world of parallel computing. I am interested in contributing to the Boost C++ Libraries because the project contains the parts of programming I like the most: optimisation and parallel programming. I have experience in C++ 98/03, 11/14, Standard Library and I worked with Git. Unfortunately I have no experience with Boost C++ Libraries. I like to work in Visual Studio on Windows and with Sublime Text and gcc, valgrind in Ubuntu. I am familiar only with JavaDoc speaking of software documentation. About the projects, I find interesting: "Concurrent Hash Tables", "Enhanced vector and deque containers" and "Boost uBLAS a library for matrix computations". I see these projects as optimisation and syncronization problems. My biggest projects are an OpenGL game written in C++ and a client-server application written in C++ too as a homework for the Protocols course. You can find them at [2]. About the application on the projects, could you tell me how I can show my skills in this field ? I searched for a section with a projects or some tests with bugs but I didn't find it. I look forward to hearing from you soon. Thank you, Alexandru Hulea [1]: alexandru.hulea(a)gmail.com [2]: https://github.com/HuleaAlexandru/c-Projects

[GSoC] [Hana] Project proposal
by Louis Dionne 22 Mar '15

22 Mar '15

Dear Boost, I plan to participate to GSoC this summer with Hana as a project. Joel Falcou, my mentor of last year, kindly agreed to mentor me again this year if I make the cut. This year's project will be much more specific than last year's. Loosely speaking, the goal is to research compile-time associative data structures and to come up with a solution that's both compile-time efficient and which has a flexible interface. You can find the current version of my GSoC proposal at [1]. Please do not hesitate to make comments if you think some things can be improved, which is probably the case. I think my colllaboration with Boost was fruitful last year, and I really hope I can reiterate this year. Regards, Louis Dionne [1]: https://gist.github.com/ldionne/171e6301ecde63712d8a

[gsoc15] Removing my proposal due to plagiarism concerns

22 Mar '15

About 12 days ago I'd posted my proposal here asking for feedback; however, it seems that some people have forked it (it's a GitHub repository) and then deleted their forked repositories. I am taking down the repository due to concerns of plagiarism. I've submitted it to Melange, and community members who want to view it/offer feedback can see it there. I hope the admins are mindful of this when evaluating proposals. It seems that there's already been a case of plagiarism here.
