Boost 1.38.0 beta 2 available
by Beman Dawes 30 Jan '09

30 Jan '09

Boost 1.38.0 beta 2 available is available from SourceForge. http://sourceforge.net/project/showfiles.php?group_id=7586&package_id=8041&… Please report any problems or comments to the users or developers mailing lists. ------------- Version 1.38.0 New Libraries * Flyweight: + Design pattern to manage large quantities of highly redundant objects, from Joaquín M López Muñoz. * ScopeExit: + Execute arbitrary code at scope exit, from Alexander Nasonov. * Swap: + Enhanced generic swap function, from Joseph Gauterin. Updated Libraries * Accumulators: + Add rolling_sum, rolling_count and rolling_mean accumulators. * Date_Time: + Added support for formatting and reading time durations longer than 24 hours with new formatter: %0. + Removed the testfrmwk.hpp file from the public include directory. + Fixed several bugs and compile errors. + For full details see the change history * Exception: + Improved and more customizable diagnostic_information output. * Hash: + boost/functional/detail/container_fwd.hpp has been moved to boost/detail/container_fwd.hpp. The current location is deprecated. + For more detail, see the library changelog. * Interprocess: + Updated documentation to show rvalue-references funcions instead of emulation functions. + More non-copyable classes are now movable. + Move-constructor and assignments now leave moved object in default-constructed state instead of just swapping contents. + Several bugfixes (#2391, #2431, #1390, #2570, #2528). * Intrusive: + New treap-based containers: treap, treap_set, treap_multiset. + Corrected compilation bug for Windows-based 64 bit compilers. + Corrected exception-safety bugs in container constructors. + Updated documentation to show rvalue-references funcions instead of emulation functions. * Math: + Added Johan Råde's optimised floating point classification routines. + Fixed code so that it compiles in GCC's -pedantic mode (bug report #1451). * Multi-index Containers: Some redundant type definitions have been deprecated. Consult the library release notes for further information. * Proto: + Fix problem with SFINAE of binary operators (Bug 2407). + Fix proto::call transform for callable transforms with >3 arguments. + result_of::value changed behavior for array-by-value terminals. + unpack_expr requires only Forward Sequences rather than Random Access Sequences. + Deprecate legacy undocumented BOOST_PROTO_DEFINE_(VARARG_)FUNCTION_TEMPLATE macros. + Add BOOST_PROTO_REPEAT and BOOST_PROTO_LOCAL_ITERATE macros to help with repetitive code generation + Support for nullary expressions with tag types other than proto::tag::terminal + Allow 0- and 1-argument variants of proto::or_ and proto::and_ * Regex: + Breaking change: empty expressions, and empty alternatives are now allowed when using the Perl regular expression syntax. This change has been added for Perl compatibility, when the new syntax_option_type no_empty_expressions is set then the old behaviour is preserved and empty expressions are prohibited. This is issue #1081. + Added support for Perl style ${n} expressions in format strings (issue #2556). + Added support for accessing the location of sub-expressions within the regular expression string (issue #2269). + Fixed compiler compatibility issues #2244, #2514, and #2458. * Unordered: + Use boost::swap. + Use a larger prime number list for selecting the number of buckets. + Use aligned storage to store the types. + Add support for C++0x initializer lists where they're available. + For more detail, see the library changelog. * Xpressive: + basic_regex gets nested syntax_option_flags and value_type typedef, for compatibility with std::basic_regex + Ported to Proto v4; Proto v2 at boost/xpressive/proto has been removed. + regex_error inherits from boost::exception Other Changes Experimental support for building Boost with CMake has been introduced in this version.

[Review] UUID review results
by Hartmut Kaiser 12 Jan '09

12 Jan '09

Hi all, Some while ago we have had a lively discussion during the review of Andy Thompkin's UUID library. I counted 11 votes, 10 'yes' votes and one 'no' vote. IMHO the 'no' vote has been superseded by the followup discussion and all issues have been resolved. Almost all reviewers stated the UUID library to be very useful. Given the overwhelming number of 'yes' votes the UUID library is accepted for inclusion into Boost. Before inclusion into the Boost SVN Andy will need to fix a couple of minor issues as discussed during the review, some of which are: - POD-ness - lexical_cast - default construction Congratulations to Andy for his effort related to pushing the UUID library forward. I hope to see active development and maintenance of this library in the future. Regards Hartmut Review Manager

by Hartmut Kaiser 10 Jan '09

10 Jan '09

Hi all, The deadline for the submission of session proposals has been extended to January 20th, 2009. No further extensions will be granted. Please find below the original call for participation. Conference registration will be available at http://www.boostcon.com/registration. Regards Hartmut ---------------------------------------------------------------------------- 3rd annual Boost Conference 2009 Aspen CO, USA, May 3-9, 2009, www.boostcon.com ---------------------------------------------------------------------------- Call for participation ---------------------- Promising to be the main face-to-face event for all things Boost (www.boost.org) BoostCon'09 opens the door to your C++ future. From using the Boost libraries to writing and maintaining them, from evangelizing to deploying Boost within your organization, from infrastructure and process to vision and mission, and from TR1 to TR2 and the new C++0x Standard, BoostCon brings together the sessions, the colleagues, and the inspiration to support your work with C++ and Boost in particular for the next year. To reflect the breadth of the Boost community, the conference includes sessions aimed at two constituencies: Boost end-users and hard-core Boost library and tool developers. The program fosters interaction and engagement within and across those two groups, with an emphasis on hands-on, participatory sessions. Session topics -------------- * Topics of interest include, but are not restricted to, the following: * General tutorial sessions introducing one or more Boost libraries * In-depth sessions on using specific libraries * Case studies on using Boost * Experts panels * Advanced sessions on implementation techniques used within Boost libraries * C++0x and how it will change life for users and library writers * TR1 and TR2 * Development workshops to extend or enhance existing Boost libraries * Workshops on design process * Infrastructure workshops such as Build tools, Website, Testing * Concepts and Generic Programming * Hardware and infrastructure presentations focused on how libraries can make better use of the technology * Other topics likely to be of great interest to Boost users and Developers. Interactive and collaborative sessions are encouraged, as this is the nature of both the on-line Boost community and the style of learning and participation that has proven most successful at such events. Sessions can be tutorial based, with an emphasis on interaction and participant involvement, or workshop based, whether hands-on programming or paper-based, discussion-driven collaborative work. Session formats --------------- Presentations ............. Presentations focus on a practitioner's ideas and experience with anything relevant to Boost and Boost users. Panels ...... Panels feature three or four people presenting their ideas and experiences relating to Boost's relevant, controversial, emerging, or unresolved issues. Panels may be conducted in several ways, such as comparative, analytic, or historic. Tutorials ......... Tutorials are sessions at which instructors teach conference participants specific Boost-relevant skills. Workshops ......... Workshops provide an active arena for advancements in Boost-relevant topics. Workshops provide the opportunity for experienced practitioners to develop new ideas about a topic of common interest and experience. Author's Corner Presentations ............................. These were introduced at BoostCon 2008, and were a great success. They are short (30 minute) sessions, focusing on tips on usage and design. In addition, we're looking to uncover the hidden design gems boost libraries. Tool Vendors Presentations .......................... We actively encourage tool vendors and ISP's to submit proposals for a special Tool Vendors Session Track aimed at products related to Boost and C++ (compilers, libraries, tools, etc.). Other formats may also be of interest. Don't hold back a proposal just because it doesn't fit into a pigeonhole. Submitting a proposal --------------------- Standard Sessions are 90 minutes. You may submit a proposal for fractions or multiples of 90-minutes. Fractional proposals will be grouped into 90 minute sessions covering related topics. Longer sessions, such as tutorials and classes, will be assigned 90 minute, three hour (i.e. half day), or six hour (i.e. full day) time slots. Please include: * The working title. * Type of session: presentation, panel, tutorial, workshop, authors corner, vendor track, other * A paragraph or two describing the topic covered, suitable for the conference web site * Proposed length: 10-20 minute short talks, 45 minutes, 90 minutes, half-day, full day * Alternate lengths, if you are willing to make adjustments: 10-20 minute lightning-talks, 45 minutes, 90 minutes, half-day, full day * Audience: users, developers, both * Level: basic, intermediate, advanced * A biography, suitable for the conference web site * Your contact information (will not be made public) Submission details ------------------ All submissions have to be done through the EasyChair conference management system: http://www.easychair.org/conferences/?conf=boostcon09. If you have not already registered at EasyChair, you will need to do so in order to submit your proposal. All submissions will go through a peer review process.

[boost] Futures Review Starts Today - January 5, 2009
by Tom Brinkman 06 Jan '09

06 Jan '09

Futures Review Starts Today - January 5, 2009 Braddock Gaskill http://braddock.com/~braddock/future Anthony Williams http://www.justsoftwaresolutions.co.uk/files/n2561_future.hpp Please review one or both libraries for submission to boost. Apparently, Anthony Williams' submission has also been sumbitted the C++ standards committee. Status unknown. As always, here are some questions you might want to answer in your review(s): What is your evaluation of the design(s)? What is your evaluation of the implementation(s)? What is your evaluation of the documentation? What is your evaluation of the potential usefulness of the library(s)? Did you try to use the library? With what compiler(s)? Did you have any problems? How much effort did you put into your evaluation(s)? A glance? A quick reading? In-depth study? Are you knowledgeable about the problem domain? Do you think the libraries should be accepted into Boost as-is or should they be merged? Apparently, there has been various discussions about these two libraries last six months. The authors will need to bring us up to date as to why they want their libraries to be reviewed seperately. Also, each author should evaluate each others library and point out the differences in their implentations. These will serve as useful discussion points. The ideal outcome in my mind would be a resubmitted submission, incorporating the best ideas from each. Tell me if you share this view or what is your preferred result. As always, your reviews will certainly assist the authors in improving their libraries even further. Thank you in advance. Please feel free to participate in any discussion even if your not going to provide a full review.

[boost] [review][constrained_value] Review of Constrained Value Library begins today
by Jeff Garland 01 Dec '08

01 Dec '08

Hi all, The review of the Robert Kawulak's Constrained Value library begins today December 1, 2008, and will end on December 10th -- I will be the review manager. Please post reviews to the developer list. Here's the library synopsis: The Boost Constrained Value library contains class templates useful for creating constrained objects. A simple example is an object representing an hour of a day, for which only integers from the range [0, 23] are valid values. bounded_int<int, 0, 23>::type hour; hour = 20; // OK hour = 26; // exception! Behavior in case of assignment of an invalid value can be customized. The library has a policy-based design to allow for flexibility in defining constraints and behavior in case of assignment of invalid values. Policies may be configured at compile-time for maximum efficiency or may be changeable at runtime if such dynamic functionality is needed. The library can be downloaded from the here: http://rk.go.pl/f/constrained_value.zip The documentation is also available online here: http://rk.go.pl/r/constrained_value --------------------------------------------------- Please state in your review, whether you think the library should be accepted as a Boost library. Additionally, please consider the following aspects in your review of the library: - What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the library? - Did you try to use the library? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? - Are you knowledgeable about the problem domain? Thanks, Jeff _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/ listinfo.cgi/boost
