Just another GSoC project idea: Create a Bjam clone based on the Boost libraries
by Boris Schäling 17 Feb '14

17 Feb '14

Create a Bjam clone based on the Boost libraries 1. Write a parser for the most important rules (exe, lib and so on) based on Boost.Spirit 2. Use the parser's actions to create a dependency tree based on Boost.Graph 3. Attach Python functions to the nodes in the dependency tree based on Boost.Python 4. Implement Python functions for one toolset (like g++) The project promises a lot of variety as different Boost libraries have to be used. It's also an opportunity to get familiar with various Boost libraries. As it can be broken down into tasks it shouldn't be that difficult to make a realistic plan for a summer project. If there is anyone interested have a look at <https://github.com/boostcon/2011_presentations/raw/master/mon/Boost.Build.p…> and <http://www.highscore.de/cpp/boostbuild/> for more information about the build system. And of course the idea is not to create a fully featured Bjam clone in a few months. If there is a binary at the end of the project which can build a software based on a simple Jamfile the project is a success. It's more important to have all the required components in place even if they are far from complete (but once they are in place it shouldn't be too difficult to extend them later and add support for another rule for example).

[container] Experimental support for memory expansion in vector and burst allocation in node containers
by Ion Gaztañaga 16 Feb '14

16 Feb '14

Hi to all, Some years later than I expected, I've committed to the master branch (after regression tests in develop were ok) a new feature for Boost.Container: new experimental allocators that support memory expansion and burst allocation in order to improve insertion and erasure times in most containers. The interface of these allocators is a variation of the interface I proposed in N2045. The interface is still experimental and not ready to be used by other containers as it's quite complex to handle and I think it can be further improved. Nevertheless, Boost.Container users can benefit from improved performance just using these allocators. The first experiment using this approach can be found in my old article "Applying classic memory allocation strategies to C++ containers" (http://www.drivehq.com/web/igaztanaga/allocplus/) In that article, Boost.Interprocess containers were modified to support N2045 and DLMalloc was version 2.8.3. In the new version the extended system allocator is based on DLMalloc version 2.8.6 (I've noticed a performance improvement in DLMalloc in the new version) and requires linking a new Boost.Container library. Boost.Container is still header-only if extended allocators are not used. DLMalloc is known to be size and speed efficient for non heavily multithreaded environments, but Boost.Container DLMalloc extension is *not* a replacement for multithreaded allocators (say ptmalloc2, ptmalloc3, nedmalloc, tcmalloc, jemalloc...). Your default system allocator will be more efficient than Boost.Container for highly multithreaded environments. On the other hand, at least in Windows and Linux, the allocator seems to be very efficient in non-multithreaded programs. The following extended allocators are provided: * boost::container::allocator: This extended allocator offers expansion, shrink-in place and burst allocation capabilities implemented as a thin wrapper around the modified DLMalloc. It can be used with all containers and it should be the default choice when the programmer wants to use extended allocator capabilities. * boost::container::node_allocator: It's a Simple Segregated Storage allocator, similar to Boost.Pool that takes advantage of the modified DLMalloc burst interface. It does not return memory to the DLMalloc allocator (and thus, to the system), unless explicitly requested. It does offer a very small memory overhead so it's suitable for node containers that allocate very small value_types and it offers improved node allocation times for single node allocations with respect to boost::container::allocator. * boost::container::adaptive_pool: It's a low-overhead node allocator that can return memory to the system. The overhead can be very low (< 5% for small nodes) and it's nearly as fast as boost::container::node_allocator. It's also suitable for node containers. More details on the implementation of this allocator can be found in http://www.drivehq.com/web/igaztanaga/allocplus/#Chapter3. The goal of these extended allocators in Boost.Container is to start building widespread existing practice in regularly requested features from container users (realloc-like behaviour in vector, amortizing several node allocation in range insertions, etc...). I'm not an allocator expert, nor a HPC guru. These new allocators are just the first step of an experiment that I hope real experts will improve. I will appreciate any comment, bug report or suggestion. Thanks, Ion

Lost the Gmane interface
by Edward Diener 16 Feb '14

16 Feb '14

Normally I post to this list using the Gmane newsgroup interface. The last message I tried to send via this interface received the response from Gmane: "You have tried posting to gmane.comp.lib.boost.devel, which is a unidirectional mailing list. Gmane can therefore not send this message to that mailing list. " Does anybody know what is happening ? I sent a message to a Gmane administrator but so far no response. Edward Diener

Hi all. I'm Lingyu Zhu, a student working on a GSOC proposal. First of all,Thanks to the admin that 2014 GSoC web page has so many great idea and they are all well-documented, especially the section describing the idea of improving boost.afio,which draw my special attention. However, there is a conspicuous typo in the header line: GGoogle Summer of Code 2014 =\ I wonder if the minor typo will effect google's judgement and thus the acceptance of boost org application. So here I am --this is my first 'bug report' ;) Best regards, Lingyu

NT² 3.0 and Boost.SIMD - Stable release
by Joel Falcou 15 Feb '14

15 Feb '14

The first stable release of the 3.x series of MetaScale’s open-source software is available: NT² 3.0. It also includes its spin-off project, Boost.SIMD (not yet a Boost library). Many Issues have been closed since last beta. The main focus of this release cycle was to fix performances issues and to stabilize some parts of the API. Next step will be to separate NT2 and Boost.SIMD into separate repositories, thus making one more step toward Boost.SIMD submission into review. [ http://www.metascale.org/nt%C2%B2-3-0-and-boost-simd ] *Changes & Bug Fixes:* - Major performance improvements in both libraries - Added experimental support for the HPX runtime for parallelization on shared memory systems - Optimizations of many elemental functions, in particuler log/ex, frexp/ldexp and cbrt - More advanced shuffle pattern recognition for SIMD - Fixed issues with Visual Studio 2013 - More functions are force-inlined to ensure good performance - New functions for conversion between types and mixing of vectors of different sizes - Demo applications usable as benchmarks - Better handling of errors when an unsupported function is called - New API for custom memory allocators Full changelog is available at https://github.com/MetaScale/nt2/releases/tag/3.0.0. *How to get it ?* - Source and binary packages can be downloaded here: http://nt2.metascale.org/downloads - The release is also available on Github : https://github.com/MetaScale/nt2/releases - The main master branch is still under development : https://github.com/MetaScale/nt2

Refactoring tools/regression and tools/release into separate sub-modules
by Beman Dawes 14 Feb '14

14 Feb '14

The tools used by regression testers and regression reporting, and the tools used by release managers are currently part of the boost-super project. As we gain experience with Git and submodules, it is becoming clear these need to be decomposed into two separate submodules. Among other advantages, that would speed work on these tools as we could better utilize volunteers without having to hand out excessive super-project write permissions. We would like one or two volunteers to do the refactoring. You don't need to be a library maintainer or release manager, although that's fine if you are. You do need git skills, as we do want to preserve history. Comments? --The release managers

Introducing Boost.Optional co-mantainer
by Fernando Cacciola 14 Feb '14

14 Feb '14

Hello, I am pleased to announce that Andrzej Krzemienski will be a co-mantainer for Boost.Optional His goal is to (finally!) implement: 1. Move semantics emulation (C++-3 compatible). 2. Function value() from tr2::optional that either returns a value or throws. For those of you who don't know Andrzej, he is the main force behind the standarizaztion of std::optional Once again, thank you very much Andrzej ! -- Fernando Cacciola SciSoft Consulting, Founder http://www.scisoft-consulting.com

path of test-binary
by dib 14 Feb '14

14 Feb '14

Hi, within the tests of a (not-yet) boost-library, how can I find out the path where b2 placed the binaries of the tests? Problem is the following: Some of the tests need the path to a shared library, which is built together with the tests. In the lib/mylib/tests/Jamfile.v2 I have the following: [...] # our test lib for shared library tests lib test_library : test_library.cpp ; test-suite mylib : # # shared library # [ run shared_library_load_test.cpp ] [ run shared_library_get_symbol_test.cpp ] # # [...] Inside shared_library_*_test.cpp I need something like this: boost::filesystem::path tstlib("bin.v2/libs/mylib/test/mycompiler/test_library.so"); As boost.build decides by itself where to put the binary, i cannot hardcode the path in the source-files.. Is there a way to get the path from boost.build? If not, how could I solve this problem? -- regards dib

[git] automated update of superproject master branch
by Peter A. Bigot 14 Feb '14

14 Feb '14

I realize there are several email threads about how the super-project branch should be managed, but most pre-date live experience with boost on git and go deep into other aspects of the issue, so I still want to call this out specially: https://svn.boost.org/trac/boost/wiki/ModBigPicture specifies that the master branch on each module should be stable at all times, which is the right policy. Currently, the master branch on the super-project is automatically updated twice(?) per hour selecting all updates to the master branches of modules. Consequently, super-project master is the exact opposite of stable. This divergence is confusing. I'm unconvinced that waiting a few days will demonstrate a significant decrease in churn on the super-project master branch. Some is due to multiple updates to specific modules, which might decrease as maintainers become more familiar with git and only push once, but interoperability issues will still arise and there will be no way to tell which master branch commits produce a working Boost installation. There is value in having a branch with automated-update semantics, but IMO regardless of what the final policy will be, "master" is not the right choice for this, and automated updates of it should stop ASAP. Perhaps the update script can simply be moved to occur on latest/master and latest/develop. Leave master untouched until whatever gets committed to it has undergone cross-toolchain integration validation, and make develop available for changes to superproject content that are not just submodule updates.

General advice needed for new maintainers.
by Fletcher, John P 14 Feb '14

14 Feb '14

I have been maintaining Boost Phoenix for several weeks. To start with I was mainly attempting to fix as many bugs as possible and also sorting out things like missing copright and licence. I am now up to the more difficult bugs which take longer to fix. I also need some more information and some actions which I cannot take myself. I have asked about a number of these on this list and I am lacking answers to a good many of them, so I am going to summarise them here. I think it would be a great help to people undertaking maintenance for the first time, without having first been an originator of a library if some guidelines were in a document. 1. General guidelines on the responsibilities of a maintainer and who is responsible for the elements outside the developer's control. In particular, what happens when there is a release of boost? 2. General guidelines on the responsibilities for bugs and who to contact if a bug seems to be due to a different library. 3. Guidelines on the use of trac and how to get given the ability to record bugs as now fixed. 4. Where is the archive for boost-bugs? It would be useful to look at past fixes to find out what has gone on. Someone suggested searching but I cannot search until I know what is there. 5. A list of who is maintaining what. 6. Documentation. I am trying to get to grips with boostbook and quickbook. Some libraries are included in a section with indexed chapters and some are not. Is there a policy about this. When I asked how Phoenix could join the only reply I had was not to bother. Is there a documentation policy? It would be good to be able to generate the web pages myself to check them when I am making changes, which may be substantial. 7. More technical. How are things to be handled in relation to C++11. (a) Things which used to work which now don't with C++11? (b) Things which only work with C++11? (c) and what about C++14? I am fixing things in an adhoc way but it would be good to have a uniform approach. 8. Boost predef for version numbers. I have introduced this into Phoenix alongside the existing method. 9. Changelog. As a user I have found this useful in libraries I have used elsewhere, so I have put one into Phoenix following the style I found in wave. There is quite a lot here, but it has been building up for some time as I find I need more information to work effectively. John Fletcher P.S. Thanks to all those who have helped me get this far.

12 Feb '14

We, mostly Ahmed Charles, will be moving the regression and release script code to independent git repos (i.e. moving the out of the boost super-repo). The first step is to copy the git histories. This requires that NO ONE make changes to the regression and release code. This first step will happen tonight at 8-12 pm PST. Further actions for testers to take will follow in the next 2-3 days. -- -- Rene Rivera -- Grafik - Don't Assume Anything -- Robot Dreams - http://robot-dreams.net -- rrivera/acm.org (msn) - grafikrobot/aim,yahoo,skype,efnet,gmail

Where is boost/detail/limits.hpp used?
by Peter Dimov 12 Feb '14

12 Feb '14

I'm playing with a dependency checker I wrote that tells me what Boost module depends on what. Starting with the basics: Dependencies for config: detail: boost/detail/endian.hpp A dependency from config to detail is not a good thing because detail depends on too much. boost/detail/endian.hpp is now only a forwarding header to predef, so it could and probably should be moved to predef, which seems to depend on nothing. But I was wondering what in config uses endian.hpp. Turns out the only use is in boost/detail/limits.hpp, a file that has been put into config for some reason. I can't find anything in config or in Boost that uses this file. What is its purpose?

[Boost-users] User/Owner Information And in Boost File System
by MANTOSH KUMAR 12 Feb '14

12 Feb '14

Hi All, Point::1 ====== boost::filesystem library is great. However I found that boost::filesystem has no interface to fetch about the owner(userid/groupid) of a particular file. "stat()" system call has been provided by POSIX compliance system to fetch this information. I am pretty sure that this must have been thought by boost community while designing boost::filesystem library and there would be valid reason not to provide such interface. However I just wanted to know the thought of boost community. Point::2 ====== The following is the code snippet: std::vector<boost::filesystem::path> vec; boost::filesystem::recursive_directory_iterator rbgnitr(p); boost::filesystem::recursive_directory_iterator renditr; for(boost::filesystem::recursive_directory_iterator itr = rbgnitr; itr != renditr; ++itr) { v.push_back(*itr); } In the above "rbgnitr" does represent the starting node in a directory. However It looked bit strange while "renditr" for end node(one beyond end). The end node renditr" is basically empty instance of class "recursive_directory_iterator"......Just wanted to know why this was designed in this way..... Thanks & Regards, Mantosh Kumar India

Boost.Log crash - question on consequences of misconfiguration
by Pieter 12 Feb '14

12 Feb '14

LS, My question regarding Boost.Log is the following: could anything been said on what to expect when asking Boost.Log to write to a non-existing directory on a read-only drive? Does it keep trying to write or give up when the directory cannot be created, and would the user be informed in such a case? Background: today I ran into a problem using Boost.Log. I configured both a Console and a TextFile backend (both autoflushing) but happened to configure the latter wrongly- setting the location of the file on a not-existing directory on a read-only drive. This caused a program crash under certain circumstances - but no problems under other circumstances (related to the configuration of the application which should not be relevant here) - when it did crash, this happened after a few messages were logged. Crash happened shortly before program termination but before the main() function was terminated (for a while I thought I was seeing the problem described in the docs regarding the boost.filesystem related problem and it took me a while to learn this was not the case).

Boost.Mixin library preliminary reviews
by Borislav Stanimirov 11 Feb '14

11 Feb '14

Hello, Boost.Mixin is a library I'm developing and I intend to submit it for review by the end of the month (most likely on Feb, 23). Source is here: https://github.com/iboB/boost.mixin Docs are here: http://ibob.github.io/boost.mixin/ There have already been two discussion on the subject: here: http://lists.boost.org/Archives/boost/2013/01/200598.php and here: http://lists.boost.org/Archives/boost/2013/07/205184.php They showed at least moderate interest in the library. Also I had a lecture about the library back in November on Open Fest 2013 Bulgaria (Unfortunately it's in Bulgarian. If you understand Bulgarian, you can find it here http://www.youtube.com/watch?v=3sTX8lUdp1c ) The feedback from the lecture has been very positive. I'm going to complete the documentation in the following day or two (it's 90% done as of now) and then focus on docs polish, like typos, structure, etc, and fixing any bugs that might arise. The library is being used in two active closed source projects, so any major bugs are highly unlikely. Currently, apart from jamfiles, there are project files for Visual Studio 2008 and 2012, QtCreator, and Code::Blocks in the repo for your convenience. Before I submit it for a formal review, It would be great if I could have some preliminary ones. Anyone is welcome with questions, suggestions, tips, and comments Thanks, -- Borislav
