utf8_codecvt facet - volunteer opportuntiy
by Robert Ramey 03 Jan '13

03 Jan '13

Our implementation for a codecvt facet internal wide char to/from utf8 format requires some maintainence. We have our own implementation since 2001. Since then, the standard libary has come to specify some implementations and some libraries have implemented some or all of this aspect of the standard library. I've come to believe that we should: a) tweak our code to use the standard library implementations if they exist. b) tweak our code to use the names of the standard library implementation b) tweak our build so that our version replaces the the standard library implementation when and only when there is no standard implemenation available. This seemingly simple task is complicated by the following circumstances. a) The relationshp between UCS and Unicode is pretty confusing. b) The iterface for codecvt is confusing. c) a number of standard library implementations have non-conforming codecvt interface. d) a number of standard library implementations don't have any codecvt header at all. This is not a problem for our current implementation because we never import it. Anyone interested in working on this should contact Marshall, Beman or myself (in that precedance). Robert Ramey

[config] Proposed BOOST_NOEXCEPT_NOTHROW macro
by Beman Dawes 03 Jan '13

03 Jan '13

The three current BOOST_NOEXCEPT* macro variants miss the case where C++03 code has a "throw()" throw-specifier. Classes that derive from standard library exceptions need this to avoid breaking code on C++03 compilers. I'm not enamored with the BOOST_NOEXCEPT_NOTHROW name, so feel free to offer suggestions for alternate names. Here is the full set of macros: #ifdef BOOST_NO_NOEXCEPT # define BOOST_NOEXCEPT # define BOOST_NOEXCEPT_NOTHROW throw() <---- new macro # define BOOST_NOEXCEPT_IF(Predicate) # define BOOST_NOEXCEPT_EXPR(Expression) false #else # define BOOST_NOEXCEPT noexcept # define BOOST_NOEXCEPT_NOTHROW noexcept <---- new macro # define BOOST_NOEXCEPT_IF(Predicate) noexcept((Predicate)) # define BOOST_NOEXCEPT_EXPR(Expression) noexcept((Expression)) #endif Unless there are objections, I'll commit the changes Wednesday afternoon Eastern US time. --Beman

[xpressive] Broken in release if explicit operator bool is available
by Andrey Semashev 03 Jan '13

03 Jan '13

Hi, With the recent change to Boost.SmartPtr that adds support for explicit operator bool() Boost.Xpressive no longer compiles. The relevant error message is: ./boost/xpressive/detail/utility/tracking_ptr.hpp:440:73: error: no type named ‘unspecified_bool_type’ in ‘class boost::intrusive_ptr<boost::xpressive::detail::regex_impl<const char*> >’ Could this be fixed?

Flow-based programming library for Boost?
by Marcus Tomlinson 03 Jan '13

03 Jan '13

Is there any interest out there for a library that allows you to create fast, efficient flow-based programs with an easy-to-use object-oriented interface? (http://en.wikipedia.org/wiki/Flow-based_programming) I've created an open-source library that does this, called "DSPatch" ( http://sourceforge.net/projects/dspatch) and would like to contribute it to the Boost Libraries. Please let me know if this sounds like something you'd like to see in Boost. Thanks!

problem with release branch serialization test results
by Robert Ramey 02 Jan '13

02 Jan '13

I recently merged the serialization library files from the trunk to the release branch. Now most of the tests on the release branch are failing. The message is: "Error extracting file: No matching files were found." Which suggested to me that I munched up the merge. But when I browse through the release branch files and log I can't see anything wrong. Would anyone have any idea what might be causing this and what I have to do to fix it? Robert Ramey

[GitHelp] odeints repository
by Karsten Ahnert 02 Jan '13

02 Jan '13

Hi, odeint has already a git repository at github (https://github.com/headmyshoulder/odeint-v2) Can this be used instead of the default boost git repository for odeint? At the moment the directory structure of this repository uses the old structure odeint odeint/boost odeint/boost/numeric/ odeint/boost/numeric/odeint odeint/libs/numeric odeint/libs/numeric/odeint odeint/libs/numeric/odeint/doc odeint/libs/numeric/odeint/test but it can easily be changed to fit to the new directory structure.

[string_ref] Feature requests
by Daniel James 01 Jan '13

01 Jan '13

Hi, I've been trying to convert quickbook to use boost::string_ref, and there are a few missing features that might be useful: Construction from a pair of iterators, either std::basic_string::const_iterator, or boost::basic_string_ref::const_iterator. Which of course can be the same type, which is annoying but not too hard to work around. Easy conversion to std::basic_string. There's a C++11 explicit string operator, but that isn't much good for portable code. Something like a 'string' or 'to_string' member would do the trick. Support for comparisons with std::basic_string. The comparison operators are templates so they aren't called with an implicit conversion. Could use a template parameter for the type so that it picks up anything which is (implicitly?) convertible to boost::basic_string_ref, maybe using SFINAE. I didn't need it, but could probably also could do with a 'hash_value' function for boost::hash support. Is potentially error prone if the original string is modified or destroy, but there are some valid use cases. thanks, Daniel

Did you reset the passwords for trunk? Until today I was able to commit changes to boost-trunk - but my password is invalid now?! Oliver

[Git] Regression testing modular Boost
by Beman Dawes 30 Dec '12

30 Dec '12

Starting a new thread - this is far to important to bury in the long documentation thread!

None yet. I've been assuming we will just update www.boost.org/development/running_regression_tests.html > What changes to the current tools need to happen to the adjust to > the new setup? As a first cut, branch the current tools and convert any code that currently uses svn commands to use git commands. But before any testing is done, it would be helpful if Boost.Build was updated to handle the generation of boost-root/boost header file links, rather than relying on the workaround cmake script. Do you feel comfortable enough with git to handle the conversion? --Beman

[Git] Modularization of Boost.Any, Boost.Array, and Boost.StaticAssert
by Daniel Pfeifer 29 Dec '12

29 Dec '12

Hi, according to our preliminary modularization, the candidates Boost.Any, Boost.Array, and Boost.StaticAssert each have their own repository, even though each of them consists of a single header file only (disregarding tests, examples and documentation). I propose to put all three of them into the Boost.Utility repository. Comments? --Daniel

[git] Boost.Build location
by Vladimir Prus 29 Dec '12

29 Dec '12

I am wondering what will be the location of Boost.Build after the git switch. It seems to be part of http://github.com/boost-lib/boost right now. Maybe, it would be best to have separate git repository for Boost.Build? In particular, that would allow to fork just Boost.Build, which is important given git's inability to handle partial checkouts. It would also allow giving push access for Boost.Build to other people, without also giving access to superproject. Comments? Thanks, Volodya

[python] Proposal: RAII for Global Interpreter Lock (GIL)
by John Zwinck 29 Dec '12

29 Dec '12

There are many questions and example classes online for dealing with Python's Global Interpreter Lock (GIL) using RAII. I think Boost.Python should provide this functionality, rather than having users who build hybrid C++/Python applications copy-pasting code from various places. I was one of those users recently, and the code I developed to deal with it is now public: https://github.com/jzwinck/pccl/blob/master/InterpreterLockGuard.hpp https://github.com/jzwinck/pccl/blob/master/InterpreterLockGuard.cpp https://github.com/jzwinck/pccl/blob/master/test/InterpreterLockGuard.test.… Comments in the header explain how to use it in the context of Boost.Python, and contain a link to a wiki from which some of the code was originally copied. Why add this to Boost? It's clearly code that a bunch of people need, often people who are already using Boost.Python. It has a permissive license, and I can re-license it if need be. And it depends on Boost (mostly for thread-specific storage--I hope this dependency won't be seen as a liability here, though it could be removed if needed). This particular implementation was used successfully in a few programs in a commercial setting on Fedora and RHEL systems. It has some extra checks that we found helpful compared to some of the versions you'll find posted online. The code also builds and passes its tests with GCC on Mac OS X. I welcome any feedback regarding the suitability for inclusion in Boost of this particular code and/or the concepts it implements. John Zwinck

Interest in serialization library
by iwg molw5 28 Dec '12

28 Dec '12

I recently wrote a small C++11 template library to unify the specification and construction of a serializable object. The library introduces a simple template markup language used to specify the layout of data on the wire, using that specification to construct the type in question much like a named tuple. A sample of the syntax used by the library is provided below: struct Object : serializable <Object, value <NAME("Field 1"), little_endian <uint32_t>>, value <NAME("Field 2"), big_endian <uint32_t>>> { }; The library is available under the MIT license at: http://www.github.com/molw5/framework with associated documentation located at: http://molw5.github.com/framework Is there any interest in including this library in Boost?
