Trac XMLRPC support
by Vladimir Prus 21 Mar '10

21 Mar '10

Would it be possible to have XMLRPC plugin installed in Boost Trac instance? See: http://trac-hacks.org/wiki/XmlRpcPlugin The installation appears to be fairly simple (and indeed seems to just work somewhere else). This will allow to use third-party tools to grab tickets from Boost Trac, which will hopefully lead to more issues fixed :-) - Volodya

Boost.Graph and SoC2010
by Cezary Bartosiak 21 Mar '10

21 Mar '10

Hello, I am writing in regards to your SoC2010 participation. I am particurarly interested in developing the Boost Graph library. I have got a working knowledge of graph and networks theory and C++ programming experience. I think I can handle any of the ideas listed in Boost.Graph section of the Project Ideas page as well as I could provide my own proposals for the library. I would like to get in touch with somebody responsible for Boost.Graph in order to talk about possibilities and what are the priorities. I would be glad to provide this person with additional information. Best, Cezary

Re: [boost] [contract] Released Contract Programming Library on SourceForge

> I have released on SourceForge a library that implements Contract > Programming (a.k.a. Design by Contract(TM) ) for C++. I am considering > to submit this library to Boost (as Boost.Contract). > Comments? Hi, Just another thought for a tiny extension that came to my mind. I tried to use the block invariant as a regular assert: int main() { CONTRACT_ASSERT_BLOCK_INVARIANT( fee fee fee ); } This code compiles and works fine. This is because "disabling block invariants" means that the entire macro invocation will disappear, inclusive of the nonsense I wrote inside. We are used to it because this is how C-style asserts work, but one of the advantage of asserts over comments, as it is often advertised, is that the predicates are checked for syntactic and (to some extent) semantic correctness. But this is not the case if we disable the assertion macros. I believe, it would be useful if "disabling block invariants" meant no run-time overhead, but still checking syntactic correctness. It would be possible if the macro CONTRACT_ASSERT_BLOCK_INVARIANT( expression ); were replaced with something like: ... sizeof( expression ) ... then, the expression is not evaluated, but required to be correct. If the value of sizeof is not used it should be eliminated by the compiler. Obviously, the same would be applicable for all the other types of checks, Regards, &rzej

GSOC 2010 : Boost.graph
by Chinmaya Poswalia 21 Mar '10

21 Mar '10

In boost.graph what would be better : a) Manipulate the original graph - it would save space(crucial for big graph) -if the user want he can copy the graph object to a new object and then feed into functions b) Generate a new graph - although space will be allocated but user has the opportunity to directly input the graph.

[Boost.Locale] More updates
by Artyom 21 Mar '10

21 Mar '10

Hello, Updates ------- I had uploaded updated version of Boost.Locale that includes few bug fixes and some cleanup of MSVC warnings so now it clearly compiles with /W3 under MSVC. Also some documentation updated. Docs: http://cppcms.sourceforge.net/boost_locale/html/ Tutorial: http://cppcms.sourceforge.net/boost_locale/html/tutorial.html Download (boost_locale-svn_r1112.zip): https://sourceforge.net/projects/cppcms/files/ Formal Review Request --------------------- I want to submit the library for formal review: - When can it be done? - Do I have to provide full BJam build before formal review (at this point it builds fine with CMake)? - Do you think that I should wait more, improve the library more and if so what exactly? Best, Artyom

[proto] call for help with msvc-7.1
by Eric Niebler 21 Mar '10

21 Mar '10

A recent check-in of mine (https://svn.boost.org/trac/boost/changeset/60706) broke proto on msvc-7.1. For instance, see <http://tinyurl.com/yg5wgw5>. I don't have access to this toolset anymore. Is there anybody out there willing to give this problem a shot? Or is it time to drop support for this old compiler? -- Eric Niebler BoostPro Computing http://www.boostpro.com

[Log] Pre-review questions
by Christian Holmquist 21 Mar '10

21 Mar '10

Hi, I'm currently attempting to convert parts of our production log system to using Boost.Log as part of my review. At first glance this looked like a trivial thing, since Boost.Log supports all features (and more!) than I would need to do this task. However, I can't find what I'm looking for in the docs and I wish to not poke around anymore in the Boost.Log code. Simple task 1 I've two source level attributes, System and Severity. I wish to create a log macro that takes these two arguments. enum System { SYSTEM_A, SYSTEM_B, }; enum SeverityLevel // I don't want to use the built-in severity enum, since need flexibility to add/remove levels. { FREQUENT, DEBUG, TEMP, INFO, WARNING, ERROR, }; void foo() { LOG(SYSTEM_A, INFO, "Hello cruel world" << "!"); } The above is not a complicated scenario and I should be able to quickly find an answer. Maybe I've just missed it..:) Simple task 2 Create a custom filter without using any Lambda magic. struct Filter { System sys; SeverityLevel sev; bool operator()(???) { // pseudo-code, since I don't know how to write this return Attributes["System"] == sys && Attributes["SeverityLevel"] >= sev; } }; Help appreciated, I would like to get to the more complicated parts.. / Christian

Heaps and Queues for GSoC
by Thomas Mullaly 20 Mar '10

20 Mar '10

Hello my name is Thomas Mullaly and I am currently an undergraduate in Kent State's Computer Science department. I'm interested in submitting a proposal for this years Google Summer of Code for the Heaps and Queues project, but, first I was wondering if somebody could explain what the requirements are for this project. So I have a better understanding of the project when I write a proposal. -Thomas Mullaly
