[review] Formal Fast-Track review of the Boost.Functional/Factory library begins today
by John Torjo 17 Dec '07

17 Dec '07

Hi all, Today starts the formal Fast-Track review of the Boost.Functional/Factory library. *Description* Factories are callback mechanisms for constructors, so we provide two function objects, boost::value_factory and boost::factory, that encasulate object construction through direct application of the constructor or operator new, respectively. These templates make other facilities that operate on function objects (such as standard algorithms, Boost.Bind, Boost.Function, or Fusion functional adapters) applicable to constructors. *Author* Tobias Schwinger *Download* Get it from here: http://www.boost-consulting.com/vault/index.php?action=downloadfile&filenam… Read documentation online here: http://torjo.com/tobias/ What to include in Review Comments ================================== Your comments may be brief or lengthy, but basically the Review Manager needs your evaluation of the library. If you identify problems along the way, please note if they are minor, serious, or showstoppers. Here are some questions you might want to answer in your review: * 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? And finally, every review should answer this question: * Do you think the library should be accepted as a Boost library? Be sure to say this explicitly so that your other comments don't obscure your overall opinion.

BoostCon 2008: May 4-9
by David Abrahams 17 Dec '07

17 Dec '07

The 2nd annual Boost Conference has been scheduled for May 4-9 2008. Please save the date! Registration should open sometime in the next week. If you want to stay at the Aspen Meadows (highly recommended as it is within walking distance of the conference venue and was the site of great after-hours discussions in '07), it's especially important this year that you book your rooms early. Since, unlike last year, Aspen's airport will be open this May, demand for rooms has been heavy. In fact, the following week, which we tried to get, was snapped up by another group before we even had a chance to catch our breath, just weeks after BoostCon'07 ended. We'll be working hard on getting the program together for 2008 over the coming weeks. We hope to include many more Boost authors and contributors, and build in several more intensive library-specific sessions, to make 2008 better than ever. Please send any questions to the BoostCon planning committee at: boostcon-plan(a)lists.boost-consulting.com Those of you who didn't make it to BoostCon'07 may want to have a look at the photo gallery at http://boostcon.com/community/photos, peruse the 2007 program at http://boostcon.com/program, and check out the two trip reports mentioned here: http://boostcon.com/news/2007/Jul/16/yet-another-trip-report. See you in Aspen! -- The BoostCon Planning Committee

[review] Gentle reminder - Fast track formal review of Boost.Functional/Factory will begin December 17
by John Torjo 12 Dec '07

Hi all, This is a gentle reminder of the Boost.Functional/Factory review, about to start next Monday. Factories are callback mechanisms for constructors, so we provide two function objects, boost::value_factory and boost::factory, that encasulate object construction through direct application of the constructor or operator new, respectively. These templates make other facilities that operate on function objects (such as standard algorithms, Boost.Bind, Boost.Function, or Fusion functional adapters) applicable to constructors.

[review] Boost.Functional/Forward - result
by John Torjo 12 Dec '07

12 Dec '07

Hi all, I'm happy to announce that The Boost.Functional/Forward library has been accepted into Boost. Congrats to Tobias for a great lib! Summary: 5 reviews, all positive. Suggestions for improvement: - Automatically detect if the compiler supports variadic templates and rvalue references and use those instead. This can be a useful portability utility when such compilers become more common. - It should use compressed_pair to store the wrapped function object to take advantage of EBO. - more tweakable parameters for specific uses - like, arity 3 for function X, and arity 5 for function Y - Docs: add more material explaining the forwarding problem - Docs: should be explicitly specified that the wrapped function object must be result_of compatible - Docs: A discussion of the impact of the library on compile time (especially with high values of N) Best, John -- http://John.Torjo.com -- C++ expert ... call me only if you want things done right

[review] Review of Unordered library begins today December 7
by Ion Gaztañaga 07 Dec '07

07 Dec '07

Hi all, The formal review of the Unordered library, proposed by Daniel James, begins today : *Description*: An implementation of the unordered containers specified in TR1, with most of the changes from the recent draft standards. *Author*: Daniel James *Download*: http://www.boost-consulting.com/vault/index.php?action=downloadfile&filenam… The documentation is in the zip file. I've put documentation online here: http://igaztanaga.drivehq.com/unordered http://tinyurl.com/yw8wjp What to include in Review Comments ================================== Your comments may be brief or lengthy, but basically the Review Manager needs your evaluation of the library. If you identify problems along the way, please note if they are minor, serious, or showstoppers. Here are some questions you might want to answer in your review: * 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? And finally, every review should answer this question: * Do you think the library should be accepted as a Boost library? Be sure to say this explicitly so that your other comments don't obscure your overall opinion. Unordered containers are likely to become one of the most used Boost libraries so I encourage you to review the library in order to see if Unordered fulfills all your expectations.

[review] Fast track formal review of Forward library begins today
by John Torjo 04 Dec '07

04 Dec '07

Hi all, The formal review of the Boost.Functional/Forward library, proposed by Tobias Schwinger, begins today : Boost.Functional/Forward provides decorator function objects to have an n-ary, generic function object accept both RValues and mutable LValues. An exponential number of overloads is needed with C98, so redundant solutions are highly undesirable. Functional/Forward is a reusable implementation asking to live in a central place in Boost. Download it from here: http://www.boost-consulting.com/vault/index.php?action=downloadfile&filenam… http://www.boost-consulting.com/vault/index.php?&direction=0&order=&directo… The documentation is included in the .zip file, in the usual place: forward/libs/functional/forward/doc/html/index.html What to include in Review Comments ================================== Your comments may be brief or lengthy, but basically the Review Manager needs your evaluation of the library. If you identify problems along the way, please note if they are minor, serious, or showstoppers. Here are some questions you might want to answer in your review: * 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? And finally, every review should answer this question: * Do you think the library should be accepted as a Boost library? Be sure to say this explicitly so that your other comments don't obscure your overall opinion. We're looking forward to your evaluation of this Boost candidate!

[boost] [review] Exception - result
by Tobias Schwinger 07 Nov '07

07 Nov '07

I'm pleased to announce that the Exception library has been accepted into boost. Thanks to all formal and informal reviewers and to Emil Dotchevski for the library! Summary of possible improvements: ================================= Design ------ Nearly all reviewers made suggestions for syntactic improvements. The "tag(value) syntax" (as suggested by John Torjo) for instance provides sufficient syntactic sugar and seems lightweight to implement. Suggested features in this area are (those are implementable on top of the current design - but will keep users from reinventing the wheel if provided by the library): - Support for grouping information, and - support for generating stack traces. I personally still have a bad feeling about 'enable_error_info' - let's just revisit and discuss it on the list before changing boost::throw_exception. The related discussions about clone/rethrow support is still ongoing. Documentation ------------- Best practices for the catch-site should be clarified in the documentation. Same goes for using the same tag multiple types with one exception object. Other comments should be addressed (I won't put much energy into summarizing documentation comments, guessing most of them might have been taken care of, already). Deployment ---------- There was a suggestion (from Pavel Vozenilek) to put #ifdef around the code of boost::exception that could be put into a separate translation unit. There should probably also be a 'build' directory and a Jamfile so there is smooth integration with the Boost build system. Of course, Jamfiles for test/examples should be added. Implementation -------------- Several reviewers noted that the library is rather allocation-heavy. It pretty much comes down to shared_ptr overuse (causing many unnecessary allocations of small objects and synchronized instructions to be executed) though not in performance critical code possibly affecting other threads and future allocations. -- Tobias Schwinger - Review Manager - _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/ listinfo.cgi/boost

[review] Exception - review period extended
by Tobias Schwinger 12 Oct '07

12 Oct '07

The review period of the proposed Exception library has been extended until October 20th. Although several people seemed interested in the submission, we only have two votes, so far. So we really need more votes. Further, I'm concerned about some potential issues, which I wouldn't want to bless into Boost without being sure there has been a thorough investigation (see below). So, I want to encourage you to evaluate the submission, in particular regarding the following questions: 1. Should the library be accepted as a Boost library? For a guideline on what to include in your evaluation see http://www.boost.org/more/formal_review_process.htm 2. Is the design of the 'enable_error_info' function (see http://www.revergestudios.com/boost-exception/boost-exception.htm#existing_… and http://www.revergestudios.com/boost-exception/boost-exception.htm#enable_er… ), using multiple inheritance, really sound? 3. Does the current implementation use appropriate data structures? We are looking forward to your reviews! Regards, Tobias Schwinger - Review Manager -
