[exception] RFC: patch for printing stacktraces during exceptions.
by Brett Lentz 27 Feb '12

27 Feb '12

Hi folks! It's been a few months since I last mailed the list. I've been working on bringing some forked changes from the Passenger project into Boost due to their more general applicability. With some help, I've got a working patch against SVN trunk that enables one of Passenger's more useful features: obtaining exception stacktraces all the way through the stack. However, due to the size of the patch and some namespacing choices made by the Phusion people, I'd like to get some feedback on this patch to ensure it's suitable for being brought into Boost. First, there's some helper classes that Phusion has put in an "oxt" namespace that I'm not really sure where they should be put or if suitable analogues already exist within Boost. For the current version of the patch, these files are simply put into 'boost/oxt' until I have a better location for them. Second, the current patch uses boost::tracable_exception. I'd like to confirm whether that is acceptable or whether I should move this to a different location in the boost namespace. Finally, any other comments about this patch are welcome. I have attached both the patch, and some example code that will demonstrate the functionality. The patch and a simple example are available here: http://wakko666.fedorapeople.org/boost/ ---Brett.

I would be interested in that static analysis tool.

vsix - template_profiler extension
by Brandon Kohn 27 Feb '12

27 Feb '12

Hello, I've put together a Visual Studio 2010 extension package which wraps the functionality of Steven Watanabe and Domagoj Saric's template_profiler to create a template profile tool. It also adds a command to profile the build time of a project or a single C++ file. Both functions are accessed from the context menu in the solution explorer tree-view. It's still fairly young and could use some kicking about. Are there any VC10 users here that would be interested in giving it a try? Cheers, Brandon

Is there interest in static code analysis?
by Antony Polukhin 27 Feb '12

Hi, I`ve recently found a tool and organization, that specializes on static code analysis for C/C++. They already interact with some famous open source projects and successfully find bugs. Looks like for open-source projects they help for free. If someone is interested, I can send their web address in private message (don`t want to ad on mailing list) Best regards, Antony Polukhin

[unicode] provide <boost/cuchar.hpp> header?
by Beman Dawes 27 Feb '12

27 Feb '12

The C++11 standard library provides a header <cuchar>, with a bit of Unicode support, based on C's <uchar.h>: Macros: __STDC_UTF_16__, __STDC_UTF_32__ Functions: mbrtoc16, c16rtomb, mbrtoc32, c32rtomb The functions provide conversion between char sequences and UTF-16/UTF-32. It would be useful to have a <boost/cuchar.hpp> header so that these functions could be used with existing compilers and standard libraries. Does anyone have an implementation of these functions they would be willing to contribute? --Beman

[mpl] ASSERT and other macros using unique IDs
by lcaminiti 26 Feb '12

26 Feb '12

Hello all, Currently BOOST_MPL_ASSERT_MSG cannot be expanded multiple times on the same line because (on GCC and alike) it uses __LINE__ to generate unique IDs. I have to program a macro that makes a bunch of static assertions when it expands so all these assertions made using BOOST_MPL_ASSERT_MSG are on the same line. I used BOOST_MPL_ASSERT_MSG_IMPL to pass the unique ID directly (which is generated by concatenating __LINE__ with the assertion counter which my macro keeps). However, this is not an ideal solution because BOOST_MPL_ASSERT_MSG_IMPL is part of a private API and it could change in the future. Is there any interest in making BOOST_MPL_ASSERT_IMPL part of the public API? (So I can directly pass the unique ID to use. I'd be best if the unique ID is not required to be numeric but just a concatenable token.) I had a similar issue with Boost.Concet's REQUIRES. #define CONTRACT_AUX_MPL_ASSERT_MSG_(counter, condition, message, types) \ /* unfortunately, need to use Boost.MPL implementation detail */ \ /* to pass unique ID (not just __LINE__) so this macro can be expanded */ \ /* multiple times on the same line if with different IDs */ \ BOOST_MPL_ASSERT_MSG_IMPL( \ BOOST_PP_CAT(BOOST_PP_CAT(message, _id_), counter), \ condition, message, types) // PUBLIC // // Allow to expand multiple assert macros on same line (without name clashes). #define CONTRACT_AUX_MPL_ASSERT_MSG(condition, message, types) \ CONTRACT_AUX_MPL_ASSERT_MSG_( \ BOOST_MPL_AUX_PP_COUNTER(), /* uses Boost.MPL impl detail */ \ condition, message, types) Thanks. --Lorenzo -- View this message in context: http://boost.2283326.n4.nabble.com/boost-mpl-ASSERT-and-other-macros-using-… Sent from the Boost - Dev mailing list archive at Nabble.com.

[gsoc] project ideas
by Andrew Sutton 26 Feb '12

26 Feb '12

Just a reminder: if you have project ideas for Google Summer of Code, please submit them, either to me or post them here https://svn.boost.org/trac/boost/wiki/SoC2012 (under "Projects"). I think that this, any project ideas are fair game. I'm not terribly concerned with completely finishing something over the course of a single summer or having a goal of getting something into the main Boost release. I'd like to foster long-term participation in the Boost community, and I'd like to see more ambition in the kinds of problems we want students to tackle. Proposals for XML, some aspects of a UI library (whatever that entails), user input library (mice, raw-mode key input, touch, and physical sensors?), networking and protocol standards, etc. should be fair game. We can always set reasonable summer-long expectations for more ambitious projects. Obviously, short-term projects are fine -- I'm linking to Feature Requests as a source of project proposals -- but I hope that won't be the only kind of project proposed. If you have ideas, please post them earlier rather than later.. Thanks, Andrew

Inconsistency between std::minmax and boost::minmax
by Marshall Clow 25 Feb '12

25 Feb '12

So, C++11 has been approved, and in the new standard library, there is: template <typename T> std::pair<const T&, const T&> minmax ( const T& a, const T& b ) but in Boost, we've got: template <typename T> tuple< T const&, T const& > minmax(T const& a, T const& b) { I can easily change boost minmax to return a pair instead of a 2-element tuple, but that's an interface change, and might break existing code. On the other hand, giving them the same interface will make it easier for people to move to C++11's library functions. Any opinions? ideas? -- Marshall P.S. boost::minmax_element, on the other hand, already returns a pair, not a two-element tuple. I'm pretty sure it doesn't satisfy the C++ complexity requirements, but that's easily fixed.
