[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?

Review Wizard Status Report for January 2006 Tom Brinkman Ronald Garcia 1) News 2) Review Managers Needed 3) Review Queue 4) Libraries Under Development //////////////////////////////////////////////////////////////////// 1) News //////////////////////////////////////////////////////////////////// Happy New Year! Here are some statistics regarding Boost Library reviews in 2005: - 12 Libraries were reviewed - 8 Libraries were accepted - 1 Library (Function Types) was accepted pending a mini-review - 2 Libraries were rejected - 1 Library has yet to receive a final verdict (ASIO) Policy Pointer has been removed from the review queue because the author has stated that it is not quite ready. We need review managers. Please take a look at the list of libraries in need of managers and check out their descriptions. If you can serve as review manager for any of them, send one of us an email. Note: If you have any suggestions about how we could improve the Review Wizard's status report, please email "reportbase at gmail dot com" and "garcia at cs dot indiana dot edu". //////////////////////////////////////////////////////////////////// 2) Review Managers Needed //////////////////////////////////////////////////////////////////// There are a few libraries in the review queue in need of review managers. If you would like to volunteer to be a review manager, please contact Ron or Tom. The following libraries still require review managers: Fusion Shmem Pimpl Pointer Type Traits (modification) Function Types //////////////////////////////////////////////////////////////////// 3) Review Queue //////////////////////////////////////////////////////////////////// Fixed Strings - January 19 2006 - January 28 2006 Intrusive Containers Function Types (mini-re-review) Shmem Fusion Pimpl Pointer Type Traits (modification) Fixed Strings Author - Reece Dunn Review Manager - Harmut Kaiser Download: Boost Sandbox (http://boost-sandbox.sourceforge.net/) under fixed_string Description: The fixed string library provides buffer overrun protection for static sized strings (char s[ n ]). It provides a C-style string interface for compatibility with C code (for example, porting a C program to C++). There is also a std::string-style interface using a class based on flex_string by Andre Alexandrescu with a few limitations due to the non-resizable nature of the class. Intrusive Containers Author - Olaf Krzikalla Review Manager - to be determined Download: http://people.freenet.de/turtle++/intrusive.zip Description: While intrusive containers were and are widely used in C, they became more and more forgotten in the C++-world due to the presence of the standard containers, which don't support intrusive techniques. Boost.Intrusive not only reintroduces this technique to C++, but also encapsulates the implementation in STL-like interfaces. Hence anyone familiar with standard containers can use intrusive containers with ease. Function Types (mini-re-review) Author - Tobias Schwinger Review Manager - to be determined Download: http://boost-sandbox.sourceforge.net/vault/ Description: This library provides a metaprogramming facility to classify, decompose and synthesize function-, function pointer-, function reference- and member function pointer types. For the purpose of this documentation, these types are collectively referred to as function types (this differs from the standard definition and redefines the term from a programmer's perspective to refer to the most common types that involve functions). The classes introduced by this library shall conform to the concepts of the Boost Metaprogramming library (MPL). The Function Types library enables the user to: * test an arbitrary type for being a function type of specified kind, * inspect properties of function types, * view and modify sub types of an encapsulated function type with MPL Sequence operations, and * synthesize function types. This library supports variadic functions and can be configured to support non-default calling conventions. Shmem Author - Ion Gaztanaga Review Manager - to be determined Download: Boost Sandbox Vault -> Memory (http://boost-sandbox.sourceforge.net/vault/index.php? direction=0&order=&directory=Memory) http://ice.prohosting.com/newfunk/boost/libs/shmem/doc/html/index.html Description: Shmem offers tools to simplify shared memory usage in applications. These include shared memory creation/destruction and synchronization objects. It also implements dynamic allocation of portions of a shared memory segment and an easy way to construct C++ objects in shared memory. Apart from this, Shmem implements a wide range of STL-like containers and allocators that can be safely placed in shared memory, helpful to implement complex shared memory data-bases and other efficient inter-process communications. Fusion Author - Joel de Guzman Review Manager - to be determined Download: http://spirit.sourceforge.net/dl_more/fusion_v2/ 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. Pimpl Pointer Author - Asger Mangaard Review Manager - to be determined Download: Boost Sandbox (http://boost-consulting.com/vault/) under pimpl_ptr. 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 greately ease the implementation of the pimpl idiom.

binary int utility: review result
by Pavel Vozenilek 11 Jan '06

11 Jan '06

Two small utilities implementing easier typing of binary numbers were reviewed from 2005/10/13. (http://lists.boost.org/boost-announce/2005/10/0072.php) One, template based, was written by Scott Schurr, second, preprocessor based, was written by Matt Calabrese. The reviewers preferred the preprocessor version more than the template based one (and thought such utility is worth to be included in Boost). So the Matt's version is accepted among Boost.Utilities. Short documentation and test cases need to be provided. Suggestions during review may be considered (e.g. shorter name). Thanks Scott and Matt for their work and apology for inexcusable delay in announcing the result. /Pavel

Boost 1.33.1 released
by Douglas Gregor 06 Dec '05

06 Dec '05

Boost 1.33.1, the latest version of peer-reviewed, portable C++ libraries, has been released. This is a bug fix release addressing many small problems with the 1.33.0 release. It is a recommended upgrade for all users of Boost 1.33.0. Boost is available at http://www.boost.org Updated Libraries include: * Any Library: Cast to reference types introduced in 1.33.0 is now documented on any_cast documentation page. * Config Library: Don't undef BOOST_LIB_TOOLSET after use. * Boost.Python: o The build now assumes Python 2.4 by default, rather than 2.2 o Support Python that's built without Unicode support o Support for wrapping classes with overloaded address-of (&) operators * Smart Pointer Library: Fixed problems under Metrowerks CodeWarrior on PowerPC (Mac OS X) with inlining on, GNU GCC on PowerPC 64. * Regex Library: Fixed the supplied makefiles, and other small compiler specific changes. Refer to the regex history page for more information on these and other small changes. * Iostreams Library: Improved the interface for accessing a chain's components, added is_open members to the file and file descriptor devices, fixed memory-mapped files on Windows, and made minor changes to the documentation. * Functional/Hash Library: Fixed the points example. * Multi-index Containers Library: Fixed a problem with multithreaded code, and other minor changes. Refer to the library release notes for further details. * Graph Library: o Fixed a problem with the relaxed heap on x86 Linux (fixes bug in dijkstra_shortest_paths). o Fixed problems with cuthill_mckee_ordering and king_ordering producing no results. o Added color_map parameter to dijkstra_shortest_paths. * Signals Library: Fixed problems with the use of Signals across shared library boundaries. * Thread library: read_write_mutex has been removed due to problems with deadlocks. * Wave library (V1.2.1) Fixed a couple of problems, refer to the change log for further details. Supported Compilers Boost is tested on a wide range of compilers and platforms. Since Boost libraries rely on modern C++ features not available in all compilers, not all Boost libraries will work with every compiler. The following compilers and platforms have been extensively tested with Boost, although many other compilers and platforms will work as well. For more information, see the regression test results. New for this release: Support for building with the newest STLport-5.0 was added. The support includes building with MinGW Runtime 3.8 plus STLport-5.0 improved to support wide character operations. Apple GCC 4.0, HP Tru64 C++, and Microsoft Visual C++ 8.0 are supported platforms. We have added an experimental autoconf-like configure script for Unix-like systems: run configure --help for more information. * Apple GCC 3.3, 4.0 on Mac OS X. * Borland C++ 5.6.4 on Windows. * GNU C++ 2.95.3 (with and without STLport), 3.2.x., 3.3.x, 3.4.x, 4.0.x on Windows, Linux and Solaris. * HP C++ for Tru64 UNIX 7.1. * Intel C++ 8.1, 9.0 on Windows, Linux. * Metrowerks CodeWarrior 8.3, 9.4, 9.5 on Mac OS X and Windows. * Microsoft Visual C++ 6.0 (sp5, with and without STLport), 7.0, 7.1, 8.0. Note: Boost does not support the non-standard "Safe" C++ Library shipping with Visual C++ 8.0, which may result in many spurious warnings from Boost headers and other standards- conforming C++ code. To suppress these warnings, define the macro _SCL_SECURE_NO_DEPRECATE. Acknowledgements Douglas Gregor managed this release. A great number of people contributed their time and expertise to make this release possible. Special thanks go to Aleksey Gurtovoy and Misha Bergal, who managed to keep the regression testing system working throughout the release process; David Abrahams, Beman Dawes, Aleksey Gurtovoy, Bronek Kozicki, Rene Rivera and Jonathan Turkanis for greatly improving the quality of this release; Rene Rivera for the new Boost web page design; and Zoltan "cad" Juhasz for the new Boost logo.

To use asio's SSL support, OpenSSL is required. OpenSSL is not necessary to use the rest of asio. asio consists only of header files, and so there is no need to build any libraries before using asio in your own applications. asio supports the following platforms and compilers: Win32 using Visual C++ 7.1 and Visual C++ 8.0. Win32 using Borland C++Builder 6 patch 4. Win32 using MinGW. Linux (2.4 or 2.6 kernels) using g++ 3.3 or later. Solaris using g++ 3.3 or later. Mac OS X 10.4 using g++ 3.3 or later.

Actually, it compiled the tests better then VC7. As for Borland 5.5, is_enum is broken and I don't see any reason to support this compiler. Alexandar requests a fast-track review. Policy Pointer Author - David Held & Jonathan Turkanis Review Manager - Gennadiy Rozenthal Download: Boost Sandbox (http://boost-sandbox.sourceforge.net/) under policy_ptr Description: Smart pointers are used to automate memory management by handling the deletion of dynamically allcoated objects (and other resources). They assist in ensuring program correctness, exception safety, and memory integrity. Policy Pointer is a policy-based smart pointer framework designed to accomodate the large number of smart pointer designs. Through the use of policy classes, virtually any smart pointer type can be constructed within this framework. This library is a Boostification of the original Loki::SmartPtr type with significant modifications. Fixed Strings Author - Reece Dunn Review Manager - to be determined Download: Boost Sandbox (http://boost-sandbox.sourceforge.net/) under fixed_string Description: The fixed string library provides buffer overrun protection for static sized strings (char s[ n ]).

Output Formatters Singleton Interfaces Output Formatters Author - Reece Dunn Download: Boost Sandbox (http://boost-sandbox.sourceforge.net/) under outfmt Description: The I/O formatters library provides an easy and customizable way to input/output arrays, STL arrays, STL collections, sub-arrays from/to STL streams. It allows you to configure how each element in such an array will be written to the stream or read from the stream, while providing reasonable defaults. Singleton Author - Jason Hise Download: http://tinyurl.com/6qvrd (old version from previous review) Description: Singleton is feature rich library: - ensuring single instance of a class and global access point to this instance - with policies specifying: - when the instance gets created (manually, immediatelly, when first used, ...) - how is the instance created (by new, malloc, in static memory, ...) - when the instance gets destroyed (never, by priority, after another singleton, ...) Parametrized singleton called Multiton is provided City::pointer p1("Chicago"); City::pointer p2("Brussels"); will create two different "singletons" of the same type. Another feature is ability to register resources (like shared pointer) who will get destroyed in controlled order, when the application exits. Not yet implemented features are: - MT safety - self-destroying singleton with timeout - bjam compatible tests The library is known to work with several newer compilers, VC7.1 among them. Help with other compilers is welcomed. Interfaces Author - Jonathan Turkanis Download: http://www.kangaroologic.com/interfaces Description: Interfaces provides a macro-based Interface Definition Language (IDL) which can be used to define C++ class types called interfaces. An interface is a lightweight value type associated with a set of named function signatures. An interface instance can be bound at runtime to any object which implements the interface, i.e., to any object of a type with accessible non-static member functions having the same name and signature as the set of functions associated with the interface. The functions of the bound object can then be invoked through the interface instance using the 'dot' operator. Binding is completely non-intrusive: the object's type need not declare any virtual functions or derive from any particluar base class. Current applications of Boost.Interfaces include: * Non-intrusive dynamic polymorphism: interfaces can often be used in place of abstract base classes, and are sometimes much faster (see Performance). * Dynamic inheritance: allows function calls to be forwarded automatically to an object specified at runtime (see Delegation). * Smart Interface Pointers: smart pointers which can manage the lifetime of any object whose type implements a given interface. * Smart References: like smart interface pointers, but the managed object is accessed using the "dot" operator."

[Review] Boost.Logging review result
by Hartmut Kaiser 15 Nov '05

15 Nov '05

Hi all, today I got the following message from John Torjo: <quote> Due to the feedback I got, I would like you to declare the library as rejected. In the light of what Gennady and others have said, indeed, another interface would be best suited for the Boost Log library. With what I know now, I would like to redesign the library from ground up, and ask for another review, probably 6 months from now or so. </quote> In the light of this announcement the review of the proposed Boost.Logging library submitted by John is closed. The library is not included into Boost. I very much hope John will find the time and energy to redesign and resubmit the library in the future. Regards Hartmut Review Manager

[Review] of binary_int utility starts
by Pavel Vozenilek 13 Oct '05

13 Oct '05

Review of binary_int utility written by Scott Schurr begins today and lasts for 7 days. The utility can be found at http://boost-consulting.com/vault/ file binary_int.zip (8 kB). ===Description=== The class template binary_int allows binary literals to be used at compile time. The template reads a binary literal value comprised of from 1 to 16 comma separated 4-bit units of ones and zeros. Example of use: #include <boost/utility.hpp> unsigned int regValue2 = binary_int<1000,1001,0011,0000>::value; enum { val1 = binary_int<1100,0010>::value, val2 = binary_int<1100,0011>::value }; switch (x) { case binary_int<0110,0001>::value: ... break; case binary_int<0111,0001>::value: ... break; } ===Alternative implementation=== Matt Calabrese had written alternative, using only preprocessor. It can be found at http://www.illegal-immigration.com/Riv/boost/binary_literal.hpp Example of use: BOOST_BINARY_LITERAL( 101 0111 1010 0110 ) (there is no need for ::value, more on http://lists.boost.org/Archives/boost/2005/09/93007.php) ===Open questions in Scott Schurs's library=== * How does it work on 64 bit systems? Could someone try? * Naming: perhaps shorter names could be used (e.g. bits/nibble) * BOOST_WORKAROUND in the code, is it really needed? === Questions for the reviewers=== * Which one of the alternatives fits in Boost better? * What is your evaluation of the implementation(s)? * Do you think the utility should be accepted as a Boost library? /Pavel
