============================================== Review Wizard Status Report for May 2010 ============================================== News ==== Boost 1.42 Released New Libraries: UUID Revised Libraries: Asio, Circular Buffer, Fusion, Graph, Integer, Iostreams, Program.Options, Property Map, Proto, Regex, Spirit, Unordered, Xpressive Meta State Machine (MSM) Library Accepted Boost 1.43 Released New Libraries: Functional/Factory, Functional/Forward Revised Libraries: Range, Accumulators, Array, Asio, Fusion, Iostreams, Multi-index Containers, Proto, Random, Spirit, Thread, Unordered, Uuid, Wave, Xpressive Open Issues =========== The Constrained Value Library was reviewed in December 2008 but no review result has been reported. We would appreciate it if someone who knows the review manager, Jeff Garland, could contact him. The following libraries have been accepted to Boost, but have not yet been submitted to SVN: * Time Series (accepted August 2007). * Floating Point Utilities (accepted March 2008). * Futures (accepted April 2009). * Polygon Library (accepted November 2009). * Geometry Library (accepted November 2009). * Meta State Machine (accepted January 2010). The following libraries have been accepted provisionally to Boost, but have not been submitted for mini-review and full acceptance: * Switch (accepted provisionally January 2008) * Phoenix (accepted provisionally September 2008) General Announcements ===================== As always, we need experienced review managers. The review queue has grown substantially but we have few volunteers, so manage reviews if possible and if not please make sure to watch the review schedule and participate. Please take a look at the list of libraries in need of managers and check out their descriptions. In general review managers are active boost participants or library contributors. If you can serve as review manager for any of them, email Ron Garcia or John Phillips, "garcia at osl dot iu dot edu" and "phillips at mps dot ohio-state dot edu" respectively. We are also suffering from a lack of reviewers. While we all understand time pressures and the need to complete paying work, the strength of Boost is based on the detailed and informed reviews submitted by you. A recent effort is trying to secure at least five people who promise to submit reviews as a precondition to starting the review period. Consider volunteering for this and even taking the time to create the review as early as possible. No rule says you can only work on a review during the review period. A link to this report will be posted to www.boost.org. If you would like us to make any modifications or additions to this report before we do that, please email Ron or John. If you're a library author and plan on submitting a library for review in the next 3-6 months, send Ron or John a short description of your library and we'll add it to the Libraries Under Construction below. We know that there are many libraries that are near completion, but we have hard time keeping track all of them. Please keep us informed about your progress. The included review queue isn't a classic queue. It is more an unordered list of the libraries awaiting review. As such, any library in the queue can be reviewed once the developer is ready and a review manager works with the wizards and the developer to schedule a review. It is not FIFO. Review Queue ============ * Lexer * Shifted Pointer * Logging * Join * Pimpl * Task * Endian * Conversion * Sorting * GIL.IO * AutoBuffer * String Convert * Containers * Type Traits Extensions * Interthreads * Bitfield * Lockfree * Fiber * Chrono * Sequence Properties * Static Size Linear Algebra * Locale -------------------- Lexer ----- :Author: Ben Hanson :Review Manager: Eric Neibler :Download: `Boost Vault <http://boost-consulting.com/vault/index.php?action=downloadfile&filename=boost.lexer.zip&directory=Strings%20-%20Text%20Processing

:Description: A programmable lexical analyser generator inspired by 'flex'. Like flex, it is programmed by the use of regular expressions and outputs a state machine as a number of DFAs utilising equivalence classes for compression. Shifted Pointer --------------- :Author: Phil Bouchard :Review Manager: Needed :Download: `Boost Vault <http://www.boost-consulting.com/vault/index.php?&direction=0&order=&directory=Memory

:Description: Smart pointers are in general optimized for a specific resource (memory usage, CPU cycles, user friendliness, ...) depending on what the user need to make the most of. The purpose of this smart pointer is mainly to allocate the reference counter (or owner) and the object itself at the same time so that dynamic memory management is simplified thus accelerated and cheaper on the memory map. Logging ------- :Author: John Torjo :Review Manager: Gennadiy Rozental :Download: http://torjo.com/log2/ :Description: Used properly, logging is a very powerful tool. Besides aiding debugging/testing, it can also show you how your application is used. The Boost Logging Library allows just for that, supporting a lot of scenarios, ranging from very simple (dumping all to one destination), to very complex (multiple logs, some enabled/some not, levels, etc). It features a very simple and flexible interface, efficient filtering of messages, thread-safety, formatters and destinations, easy manipulation of logs, finding the best logger/filter classes based on your application's needs, you can define your own macros and much more! Join ---- :Author: Yigong Liu :Review Manager: Needed :Download: http://channel.sourceforge.net/ :Description: Join is an asynchronous, message based C++ concurrency library based on join calculus. It is applicable both to multi-threaded applications and to the orchestration of asynchronous, event-based applications. It follows Comega's design and implementation and builds with Boost facilities. It provides a high level concurrency API with asynchronous methods, synchronous methods, and chords which are "join-patterns" defining the synchronization, asynchrony, and concurrency. Pimpl ----- :Author: Vladimir Batov :Review Manager: Needed :Download: | `Boost Vault <http://www.boost-consulting.com/vault/index.php?action=downloadfile&filename=Pimpl.zip&directory=&

:Description: The Pimpl idiom is a simple yet robust technique to minimize coupling via the separation of interface and implementation and then implementation hiding. This library provides a convenient yet flexible and generic deployment technique for the Pimpl idiom. It's seemingly complete and broadly applicable, yet minimal, simple and pleasant to use. Task ---- :Author: Oliver Kowalke :Review Manager: Needed :Download: `Boost Vault <http://www.boostpro.com/vault/index.php?action=downloadfile&filename=boo...

:Description: Formerly called Thread Pool The library provides: * thread creation policies: * determines the management of worker threads: * fixed set of threads in pool * create workerthreads on demand (depending on context) * let worker threads ime out after certain idle time * channel policies: manages access to queued tasks: * bounded channel with high and low watermark for queuing tasks * unbounded channel with unlimited number of queued tasks * rendezvous syncron hand-over between producer and consumer threads * queueing policy: determines how tasks will be removed from channel: * FIFO * LIFO * priority queue (attribute assigned to task) * smart insertions and extractions (for instance remove oldest task with certain attribute by newest one) * tasks can be chained and lazy submit of taks is also supported (thanks to Braddocks future library). * returns a task object from the submit function. The task it self can be interrupted if its is cooperative (means it has some interruption points in its code -> ``this_thread::interruption_point()`` ). Endian ------ :Author: Beman Dawes :Review Manager: Needed :Download: http://mysite.verizon.net/beman/endian-0.10.zip :Description: Conversion ---------- :Author: Vicente Botet :Review Manager: Needed :Download: `Boost Vault <http://www.boostpro.com/vault/index.php?action=downloadfile&filename=conversion.zip&directory=Utilities&;

`__

:Description: Generic explicit conversion between unrelated types. Boost.Conversion provides: * a generic ``convert_to`` function which can be specialized by the user to make explicit conversion between unrelated types. * a generic ``assign_to`` function which can be specialized by the user to make explicit assignation between unrelated types. * conversion between ``std::complex`` of explicitly convertible types. * conversion between ``std::pair`` of explicitly convertible types. * conversion between ``boost::optional`` of explicitly convertible types. * conversion between ``boost::rational`` of explicitly convertible types. * conversion between ``boost::interval`` of explicitly convertible types. * conversion between ``boost::chrono::time_point`` and ``boost::ptime``. * conversion between ``boost::chrono::duration`` and ``boost::time_duration``. Sorting ------- :Author: Steven Ross :Review Manager: Needed :Download: `Boost Vault <http://www.boostpro.com/vault/index.php?action=downloadfile&filename=alg...

`__

:Description: A grouping of 3 templated hybrid radix/comparison-based sorting algorithms that provide superior worst-case and average-case performance to std::sort: integer_sort, which sorts fixed-size data types that support a rightshift (default of >>) and a comparison (default of <) operator. float_sort, which sorts standard floating-point numbers by safely casting them to integers. string_sort, which sorts variable-length data types, and is optimized for 8-bit character strings. All 3 algorithms have O(n(k/s + s)) runtime where k is the number of bits in the data type and s is a constant, and limited memory overhead (in the kB for realistic inputs). In testing, integer_sort varies from 35% faster to 8X as fast as std::sort, depending on processor, compiler optimizations, and data distribution. float_sort is roughly 7X as fast as std::sort on x86 processors. string_sort is roughly 2X as fast as std::sort. GIL.IO ------ :Author: Christian Henning :Review Manager: Needed :Download: `GIL Google Code Vault <http://gil-contributions.googlecode.com/files/rc2.zip

`__

:Description: I/O extension for boost::gil which allows reading and writing of/in various image formats ( tiff, jpeg, png, etc ). This review will also include the Toolbox extension which adds some common functionality to gil, such as new color spaces, algorithms, etc. AutoBuffer ---------- :Author: Thorsten Ottosen :Review Manager: Needed :Download: `Here <http://www.cs.aau.dk/~nesotto/boost/ auto_buffer.zip>`__ :Description: Boost.AutoBuffer provides a container for efficient dynamic, local buffers. Furthermore, the container may be used as an alternative to std::vector, offering greater flexibility and sometimes better performance. String Convert -------------- :Author: Vladimir Batov :Review Manager: Needed :Download: `Boost Vault <http://www.boostpro.com/vault/index.php?action=downloadfile&filename=boo...

`__

:Description: The library takes the approach of boost::lexical_cast in the area of string-to-type and type-to-string conversions, builds on the past boost::lexical_cast experience and advances that conversion functionality further to additionally provide: * throwing and non-throwing conversion-failure behavior; * support for the default value to be returned when conversion fails; * two types of the conversion-failure check -- basic and better/safe; * formatting support based on the standard I/O Streams and the standard (or user-defined) I/O Stream-based manipulators (like std::hex, std::scientific, etc.); * locale support; * support for boost::range-compliant char and wchar_t-based string containers; * no DefaultConstructibility requirement for the Target type; * consistent framework to uniformly incorporate any type-to-type conversions. It is an essential tool with applications making extensive use of configuration files or having to process/prepare considerable amounts of data in, say, XML, etc. Containers ---------- :Author: Ion Gaztanaga :Review Manager: Needed :Download: http://www.boostpro.com/vault/index.php?action=downloadfile&filename=boost.move.container.zip&directory=Containers& :Documentation: http://svn.boost.org/svn/boost/sandbox/move/libs/container/doc/html/index.ht... :Description: Boost.Container library implements several well-known containers, including STL containers. The aim of the library is to offers advanced features not present in standard containers or to offer the latest standard draft features for compilers that comply with C++03. Type Traits Extensions -------------------------- :Author: Frederic Bron :Review Manager: Needed :Download: http://svn.boost.org/trac/boost/browser/sandbox/type_traits :Description: The purpose of the addition is to add type traits to detect if types T and U are comparable in the sense of <, <=, >, >=, == or != operators, i.e. if t,
