[git] creation of .gitignores
by Jürgen Hunold 25 Oct '13

25 Oct '13

Hi, the converted repository is missing .gitignores. svn provides the ignores patterns in the "svn:ignore" property. The question is: Can those patterns be extracted by the conversion script or shall manually create .gitignores in current svn (patch attached). The third option is to add them after the conversion. Adding (and modifying) the .gitignores during the conversion has the advantage of having .gitignores throughout the whole history instead of only "now". Any comments? Yours, Jürgen -- * Dipl.-Math.

[git help] Documenting common modular boost workflows
by Beman Dawes 25 Oct '13

25 Oct '13

I think we need to document simple suggested modular boost workflows. Each workflow could start with the assumption that the steps described in https://svn.boost.org/trac/boost/wiki/TryModBoost have been completed. Workflows might include: 1) Switch to the "develop" branch, fix a minor problem, test, commit, switch back to "master". 2) Same as (1) but also push to remote. 3) Same as (2) but also merge develop to master. 4) Same as (3) but end by submitting a pull request to the boost super-project. I don't mind writing the actual wiki pages, but am a little hobbled by being a TortoiseGit rather than command line git user, and by never having worked with sub-modules. So what would recommended git commands look like for one or more of the above workflows? Thanks, --Beman

[utility][enable_if] Documentation issue
by Agustín K-ballo Bergé 25 Oct '13

25 Oct '13

The documentation for `enable_if` has a duplicated anchor for sections 3.1 and 3.2, making it impossible to link to section 3.2 directly. See http://www.boost.org/libs/utility/enable_if.html#htoc7 This issue is still present in trunk. Could this be fixed? I could provide a patch but I do not see a .qbk file for it, should the html be modified directly? Regards, -- Agustín K-ballo Bergé.- http://talesofcpp.fusionfenix.com

[Type_Traits] [remove_bounds]: Wrong workaround for IBM C++ compiler is applied in remove_bounds.hpp
by Kilian Kilger 24 Oct '13

24 Oct '13

Hi, in remove_bounds.hpp, a wrong workaround for the IBM C++ compiler is applied. This workaround is only valid for IBM C++ on AIX, but wrong for IBM C++ on z/OS. The z/OS compiler has no bug and thus no workaround must be applied (else we get wrong results). So instead of testing against __IBMCPP__ one should also test against __MVS__. This last macro is only defined for IBM C++ on z/OS. I wanted to open a ticket on trac, but this system did always identify my posting as spam. Best regards, Kilian.

[functors] proposal
by Piotr Wygocki 24 Oct '13

24 Oct '13

Hi, I've developed a small set of functors and functor adaptors. Although this code is very simple it might be very useful for some subset of the community. Do you think it might become a part of the boost library? If not I'm still very interested in any feedback. I think it's not big enough to be a separate library. To my knowledge of boost it fits in the utility lib. The code can be found here: https://github.com/wygos/functors List of utilities: SkipFunctor takes any number of arguments; does completely nothing ReturnSomethingFunctor<T,t> takes any number of arguments; returns t; IdentityFunctor takes one parameter and returns it. ReturnFalseFunctor takes any number of arguments; returns false; ReturnTrueFunctor takes any number of arguments; returns true; ReturnZeroFunctor takes any number of arguments; returns 0; AssertFunctor takes any number of arguments; asserts; ArrayToFunctor<Array> Stores an object which provides operator[]. Provides operator()(). A set of non-template comparison functors (only operator() is templated): * Greater * Less * GreaterEqual * LessEqual * EqualTo * NotEqualTo FunctorToComparator<Functor, Compare> This comparator takes a functor "f" and a comparator "c". For elements (x,y) it returns c(f(x), f(y)) c is Less by default FunctorToOutputIterator<Functor> The output iterator stores a functor and each time the operator= is called the given functor is called Logical operators as functors: * Not * Or * And * Xor LiftBinaryOperatorFunctor<Operator, FunctorLeft, FunctorRight> Functor stores a binary operator "o" and two functors "f" and "g". For given arguments args returns o(f(args), g(args)). Boolean functor adapters. Each of them stores a boolean functor and performs an appropriate logical operation in the operator(). * NotFunctor<Functor> * OrFunctor<FunctorLeft, FunctorRight> * AndFunctor<FunctorLeft, FunctorRight> * XorFunctor<FunctorLeft, FunctorRight> Regards, Piotr

Hi Folks, starting with last nights run my tester has been failing with : File "/home/michael/boost_testing/tools_regression_src/regression.py", line 329, in command_test self.command_test_boost_build() File "/home/michael/boost_testing/tools_regression_src/regression.py", line 369, in command_test_boost_build "boost/bin.v2/libs/any/test/any_test.test")); OSError: [Errno 2] No such file or directory: '/home/michael/boost_testing/results/boost/bin.v2/libs/any/test/any_test.test' Is there an easy an easy way for me to determine the missing test? thanks michael

[website] Redirection to latest documentation
by Laurent Dupuy 23 Oct '13

23 Oct '13

Hello all, Would it be possible for the webmaster(s) to add a redirection (a symbolic link or whatever) to the latest documentation? Until recently, the URL http://www.boost.org/doc/libs/ did the job, but it does not anymore. Thanks! -- Laurent Dupuy.
