[review][pimpl_ptr] Pimpl Pointer review begins
by Rene Rivera 15 May '06

15 May '06

The review of the pimpl_ptr library by Asger Mangaard starts today, Monday May 15th, 2006, and runs through May 25th, 2006. (Boost Reviews RSS feed <http://tinyurl.com/ogpj6>) Pimpl Pointer ------------- :Author: Asger Mangaard :Download: Boost Sandbox (http://boost-consulting.com/vault/) as "pimpl_ptr.zip". Direct download at <http://tinyurl.com/m66ox>. :Description: The pimpl idiom is widely used to reduce compile times and disable code coupling. It does so by moving private parts of a class from the .hpp file to the .cpp file. However, it's implementation can be tricky, and with many pitfalls (especially regarding memory management). The pimpl_ptr library is a single header file, implementing a special policy based smart pointer to greatly ease the implementation of the pimpl idiom. Review questions ---------------- Please always explicitly state in your review, whether you think the library should be accepted into Boost. You might want to comment on the following questions: - 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?

[review] Fusion review begins
by Ronald Garcia 10 May '06

10 May '06

The review of Joel de Guzman's Fusion library begins today, May 1, 2006, and continues through May 10, 2006. :Download: http://spirit.sourceforge.net/dl_more/fusion_v2.zip :Description: Fusion is a library of heterogenous containers and views and algorithms. A set of heterogenous containers (vector, list, set and map) is provided out of the box along with view classes that present various composable views over the data. The containers and views follow a common sequence concept with an underlying iterator concept that binds it all together, suitably making the algorithms fully generic over all sequence types. The architecture is somewhat modeled after MPL which in turn is modeled after STL. It is code-named "fusion" because the library is the "fusion" of compile time metaprogramming with runtime programming. Review questions ================ Please always explicitly state in your review, whether you think the library should be accepted into Boost. You might want to comment on the following questions: - 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?

[Boost Review] Property Tree Library
by Thorsten Ottosen 19 Apr '06

19 Apr '06

Dear All, I have the great pleasure to announce that the formal boost-review of Marcin Kalicinski Property Tree Library begins now (the 18th of April) and runs through the 27th of April. Introduction ------------ This fairly high-level library consists of the following facilities: 1. a generic recursive property-tree data-structure 2. generic conversions to/from this data-structure from/to a. xml-files b. ini-flies c. json-files d. windows registry files As an example of how powerful the library is, consider this tutorial: - http://kaalus.atspace.com/ptree/doc/index.html#five_minute_tutorial The library may be downloaded from - the boost file vault http://boost-consulting.com/vault/ (property_tree_rev5.zip) - tinyurl: http://tinyurl.com/fkt7r - boost sandbox: http://www.boost.org/more/mailing_lists.htm#sandbox (look in boost/property_tree and libs/property_tree) The documentation may be viewed online at - http://kaalus.atspace.com/ptree/doc/index.html If your find the above interesting, please consider submitting a review to the boost developer mailing list: - http://www.boost.org/more/mailing_lists.htm#main You might end up using several hours on a review, but the end result could be a superb library that will save you weeks of work. Notes for reviewers ------------------- When writing your review, you may wish to consider the following questions: * 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. In particular, consider if you can answer the following questions: - was the library suitable for your daily xml-tasks? If not, what was missing? - was the library's performance good enough? If not, can you suggest improvements? - was the library's design flexible enough? If not, how would you suggest it should be redesigned to broaden its scope of use? best regards Thorsten Ottosen, Review Manager

[review] promotion traits - result
by Tobias Schwinger 12 Apr '06

12 Apr '06

Dear Boost community, Alexander Nasonov's Promotion Traits have been accepted conditionally into Boost with 4/4 positive votes. The conditions are - an example must be added to the documentation (plus accompanying source code for the example folder), - the reference should be clarified (cv-qualification, bit fields) - further conditions might arise from the merger with the extended library (TypeTraits) and are subject to synchronization with the library maintainer (John Maddock). Thanks to Alexander for the submission and to our reviewers for their work! Regards, Tobias (Review Manager)

[review] promotion traits - review period extended until April 9.
by Tobias Schwinger 06 Apr '06

06 Apr '06

Dear users & members of Boost, I decided to extend the review period of the fast-track review for Promotion Traits until April 9 because there were only three reviews until now. That is, you have another three days to submit your evaluation of the proposed Boost software. Cheer up, it's a small & fast-to-track submission! We're very much looking forward to your reviews. Download URL ============ http://cpp-experiment.sourceforge.net/promote-20050917.tar.gz About the submission ==================== The Promotion Traits extend Boost.TypeTraits with templates that compute the type after promotion has been applied. Example: // given template<typename T> struct some_algorithm; template<> struct some_algorithm<int> { [...] }; // [...] more specializations // , [...] some_algorithm< typename integral_promotion<T>::type > [...] // makes some_algorithm work for any type T that promotes to an integer // (that is enums and smaller integral types) without the need for // additional specialization Review questions ================ Please always explicitly state in your review, whether you think the library should be accepted into Boost. You might want to comment on the following questions: - 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?

[Review] Shmem library review results
by Fred Bertsch 17 Feb '06

17 Feb '06

Hello everyone, The formal review of Ion Gaztañaga's Shmem library ended yesterday. I am pleased to announce that it was accepted into Boost! This library clearly generated a lot of interest from people since we got quite a few reviews. All of them were positive. During the discussion, some weaknesses in the library were found, and Ion has agreed to correct them. These include: - Improvements to the documentation and example code. - Clearer documentation on which header files to include for which objects. - Removing the 2-phase construction mechanism and replacing them with RAII-only constructors. - Adding !is_polymorphic static asserts when inserting an object into shared memory. Several difficult issues were raised during the review that will not be solved immediately. These include: - Security information about the shared memory object is currently avoided. - The synchronization objects have some weaknesses. Some of these weaknesses are related to the same weaknesses in Boost.Threads. - Memory mapped file regions are not separate from memory mapped files in the current implementation. - Multi-segment shared memory that would allow the shared memory object to grow. Perhaps these issues could be dealt with in a future version. Thank you, everyone, for the reviews and discussions about Shmem. This library should be extremely useful to those doing IPC. -Fred Bertsch

[Review] Shmem Library
by Fred Bertsch 06 Feb '06

06 Feb '06

Hello everyone, The review of the proposed Boost Shmem library written by Ion Gaztañaga starts today (February 6th, 2006) and ends after 10 days (February 16, 2006). Documentation for the library can be found online here: http://tinyurl.com/e2os3 Both documentation and the library itself can be downloaded here: http://tinyurl.com/9t5qy --------------------------------------------------- About the library: The Shmem Library simplifies the use of shared memory and provides some STL compatible allocators that allow shared memory STL container placement. It also offers helper classes, such as offset pointers, process shared mutexes, condition variables, and named semaphores. Library users can apply all STL algorithms and utilities with created shared memory objects. Shmem also wants to present a portable implementation, unifying UNIX and Windows shared memory object creation, providing simple wrapper classes. Shmem offers the following to the user: - Portable synchronization primitives for shared memory, including shared mutexes and shared condition variables. - Dynamic allocation of portions of a shared memory segment. - Named allocation in shared memory. Shmem can create objects in shared memory and associate it with a c-string offering a similar mechanism to a named new/delete. Created object can be found by other processes using Shmem framework. - Offset pointers that can be safely placed in shared memory to point to another object of the same shared memory segment even if the memory is mapped to a different address. - STL compatible shared memory allocators so that STL containers can be placed in shared memory. Shmem also offers a pooled node allocator to save and optimize shared memory allocation in node containers. - STL compatible containers for systems with STL implementations that cannot deal with shared memory. The user can map shared memory to different addresses and use STL compatible containers and algorithms. Useful to store common data or implement shared memory databases. These containers also show how STL compatible containers can make use of shared memory STL compatible allocators to place such containers in the shared memory. Shmem also offers the basic_string pseudo-container to use full-powered C++ strings in shared memory. --------------------------------------------------- Please always state in your review, whether you think the library should be accepted as a Boost library! Additionally please consider giving feedback on the following general topics: - 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?

[Review] Fixed strings library
by Hartmut Kaiser 05 Feb '06

05 Feb '06

Hi all, the formal review period of the Fixed strings library written by Reece Dunn ends today. Since there was complete consent with regard to this library among all submitted reviews, it is straight forward for me to make the final decision. The library is rejected and will not be included into Boost at this point in time. The main points listed during review were: - Do we need a fixed_string library at all, is it worth the overhead? - Insufficient/confusing documentation . insufficient description of general design, design rationales and motivations . it says more about implementation details rather then the public interface . missing or insufficient documentation of parts of the library - The overall architecture of the implementation is too complicated and needs to be reworked - Missing interface for construction/interaction with std::string's - Unclear benefit to have the strings truncated to avoid overflows - Missing performance comparison with std::string and other alternatives - Compilation problems with the library as submitted for review Reece already expressed his interest to resubmit the library for review again, after he has been able to address the mention issues. I'ld like to thank Reece for submitting this library and all reviewers for their time they invested in preparing the reviews. Regards Hartmut Review Manager

[Review] Formal review of Fixed Strings library starts today
by Hartmut Kaiser 19 Jan '06

19 Jan '06

Hi all, The review of the proposed Boost Fixed Strings library written by Reece Dunn starts today (January 19th, 2006) and ends January 28th, 2006. You can download the library here: http://tinyurl.com/czrh9 --------------------------------------------------- About the library: The fixed_strings library is a buffer-overrun safe version of using fixed-size character array data buffers. It provides integration with the C API allowing strcpy, et. al. to be used safely for a fixed string and provides a basic_string interface allowing easy migration to C++ strings. There is also a formatter function object allowing (w)sprintf to be used in a single line! Example: boost::fixed_string< 5 > hi; strcpy( hi, "Hello World" ); hi.push_back( '!' ); std::cout << hi << std::endl; std::cout << boost::formatter( "Meine %s Welt!", "kleine" ) << std::endl; output: Hello Meine kleine Welt! --------------------------------------------------- Please always state in your review, whether you think the library should be accepted as a Boost library! Additionally please consider giving feedback on the following general topics: - 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?
