Line endings fixes
by Vitaly Budovski 13 Aug '13

13 Aug '13

Hi, Please see the attached files. boost_endings1.patch just sets some of the cpp and other text files to have file endings consistent with the rest of the repository. boost_endings2.patch may be controversial as it does the same but for the svg files. Some of them are marked as text, others as binary. It's a real mess. Most of the svg files are generated from other sources so should probably be omitted from the repository and simply regenerated when docs are built. Came across these issues when checking out the modularised boost git repository. Regards, Vitaly

unique_ptr for C++03
by Andrew Ho 13 Aug '13

13 Aug '13

Hi, I implemented std::unique_ptr using C++03 features plus a few other Boost Libraries. Incidentally, I also implemented default_delete (which binds to std::default_delete if available) because it's required for unique_ptr. https://github.com/helloworld922/unique_ptr The library binds to std::unique_ptr if standard library support is available. There are a few things I don't think I'll be able to emulate exactly. Namely: - I don't think the deleter can ever be forwarded correctly (limitation of C++03). Ideas/suggestions for how to best handle this are welcome (currently, I move the deleter if E == D and copy otherwise, I think) - There's no explicit conversion overloads in C++03. Currently I have operator bool() implemented non-explicitly if there's no compiler support, relying on the user to only use it "as-if explicit". An alternative solution is to remove the typecast operator and force users to use get() == NULL_VALUE. - functions relying on nullptr_t are only enabled if compiler support is available. Again, I don't think there's any possible work-around for C++03. There are also a few missing features (still working on the implementation): - make_unique (part of c++14) - nullptr_t comparison operators Current dependencies (assuming no C++11 std::unique_ptr): - Boost.Config - Boost.Move - Boost.TypeTraits Comments/Feedback is welcome.

Location for library-specific utility files in Subversion trunk
by Jeremiah Willcock 12 Aug '13

12 Aug '13

I have a file containing the list of unmerged changes from BGL and some command lines to simplify merging changes from the trunk to the release branch and to help in writing release notes. They are not useful to have in a release, but I would like to have them stored somewhere other than just my home directory. Is there a path designated for that? Somewhere inside tools/release/? -- Jeremiah Willcock

Inspection report: revision used?
by Joaquin M Lopez Munoz 11 Aug '13

11 Aug '13

Hi, The current inspection report, dated 15:30:32 UTC, Saturday 10 August 2013: http://boost.cowic.de/rc/docs-inspect-release.html fails to state the SVN revision being inspected The files checked were from unknown at revision unknown As it happens, whatever revision of the code is being used it has to be older than Aug 10, since the error reported at http://boost.cowic.de/rc/docs-inspect-release.html#flyweight has been fixed as of Aug 6, i.e. four days before: https://svn.boost.org/trac/boost/changeset/85227 Just a heads up in case there's something to fix on the inspection report running engine.

[mixin] New library reminder
by Borislav Stanimirov 11 Aug '13

11 Aug '13

Hello, Some of you might remember the previous discussion on the subject (archived here: http://lists.boost.org/Archives/boost/2013/01/200598.php) Anyway, in short, I'm developing a library with the intention to formally submit it to Boost by the end of the year. You can find it here: https://github.com/iboB/boost.mixin The latest news about it is that I think that the library's features for the formal submission are done and all that's left are minor tweaks, bug fixes, tests, examples, and, most importantly, a complete documentation. In the meantime, I again invite you all to check it out. Any comments, suggestions, and questions will be greatly appreciated. Thanks, -- Borislav

Releasing Boost Dependency Analyzer 1.1
by Jens Weller 11 Aug '13

11 Aug '13

Hello boost community, a short notice that I just have released the version 1.1 of my dependency analyzing tool for boost. For now I have only managed to get a proper Windows Version, Linux Version will follow later. New Features: Configuration - the tool remembers the path to bcp now - select the source for libraries - maintainers.txt - libraries.xml - 2 filter options - filter libraries by name - filter edges by type, for now its header, source/lib, test and documentation. Export: - Export CSV File which has all libraries and the number of dependencies (sorted) libraries.xml - this is now a optional source for the library names Some feedback: libraries.xml as a lib name source is nice, but not quite perfect. I've seen different results from maintainers.txt and libraries.xml. As maintainers.txt also libraries.xml contains duplicates, some of its library names don't fit the expectation of bcp, so I applied some fixes for this in my program. The Dependency filter is yet not perfect, especially in detection. More details about this version and the download for it at my blog: http://www.meetingcpp.com/index.php/br/items/releasing-boost-dependency-ana… kind regards, Jens Weller

Boost 1.54 build problem: --without-context not honoured?
by Steve M. Robbins 11 Aug '13

11 Aug '13

Hi, I'm digging into a build problem and noticed that even though I specify "./bjam --without-context", Boost.Context is still built! The bjam configuration output states that Context is not to be built: Component configuration: - atomic : building - chrono : building - context : not building - coroutine : building - date_time : building - exception : building But it is built nonetheless. This causes a build failure for architectures which are not supported; see build log [1]. Compare that to the build for 1.53 [2] which works fine. I've diffed the libs/context directory between 1.53 and 1.54 and nothing jumps out at me as the cause. Has anyone noticed and fixed this already? Thanks, -Steve [1] https://buildd.debian.org/status/fetch.php?pkg=boost1.54&arch=ia64&ver=1.54… [2] https://buildd.debian.org/status/fetch.php?pkg=boost1.53&arch=ia64&ver=1.53…

[preprocessor] nested for_each not working like expected
by Eric Niebler 10 Aug '13

10 Aug '13

I can't figure out what I'm doing wrong. According to the docs, this should work: #define S0 (0)(1)(2)(3) #define S1 (5)(6)(7)(8) #define M4(R, DATA, ELEM) (DATA,ELEM) #define M2(R, DATA, ELEM) BOOST_PP_SEQ_FOR_EACH_R(R, M4, ELEM, S1); BOOST_PP_SEQ_FOR_EACH(M2, ~, S0) I expect to get a sequence like (0,1)(0,2)... for each combination. I get gibberish. (Please don't tell me to use FOR_EACH_PRODUCT. In my real use case, M2 and M4 are far more complicated, and a simple product won't do.) Can anybody please tell me what I'm doing wrong? TIA, -- Eric Niebler Boost.org
