[units] objects with internal linkage in headers
by Steven Watanabe 13 Feb '07

13 Feb '07

AMDG All the static const objects in the library cause ODR violations for functions that use them. You can avoid this by only putting a reference in the unnamed namespace. #define BOOST_UNITS_STATIC_CONSTANT(type, name) \ template<bool> struct name##_intance_t { \ static const type instance; \ }; \ namespace { \ const type& name(name##_intance_t<true>::instance);\ } \ template<bool b> \ type name##_intance_t<b>::instance BOOST_UNITS_STATIC_CONSTANT(energy, joule); BOOST_UNITS_STATIC_CONSTANT(typeof(1.0*meters/second) , c) = 299792458*meters/second; In Christ, Steven Watanabe

local variable shadowing
by Chris Saunders 12 Feb '07

12 Feb '07

This is a minor coding style feature request: I find local variable shadow warnings helpful, but when I include my favorite boost libraries (lexical casts, pool allocators, random numbers) I always have to do a bit of patching to remove the warnings within boost first. While this is pretty easy to do, I thought I'd check whether this could be fixed on mainline. So, 1) what's the process for submitting patches for this? Do I just go through each library maintainer? and 2) is there any way to get a visible warning (the equivalent of gcc's -Wshadow) into the boost build/test process? Thanks, -Chris

Review Managers Needed
by Tom Brinkman 12 Feb '07

12 Feb '07

We need volunteer review managers for most of the libraries in the review queue. If your interested, let us know. Preferably, you would have a background in the problem domain, but no association with the library and a contributer to the boost mailing list. The review schedule is available here: http://www.boost.org/more/formal_review_schedule.html . You can read the "review manager" requirements at the following link: http://www.boost.org/more/formal_review_process.htm Most of the libraries are located at the Boost Sandbox Vault, located here: http://boost-consulting.com/vault/ Maintainers of the Review Queue: Ronald Garcia (garcia (at) cs.indiana.edu) Tom Brinkman (reportbase (at) gmail.com) If there is any errors or ommisions in this report, please send them to Ron or Tom. Here is a summary of the libraries that are in the queue. ------------------------------------- Library: Exception Author: Emil Dotchevski Location: http://www.revergestudios.com/boost-exception/boost-exception.zip Review Manager: Needed Date: Needed Summary: The purpose of Boost Exception is to free designers of exception classes from having to consider what data needs to be stored in exception objects in order for the catch site to be able to make sense of what went wrong. When Boost Exception is used, arbitrary values can be stored in any exception. This can be done directly in the throw-expression, or at a later time as the exception object propagates up the call stack. The ability to add data to any exception object after it has been thrown is important, because often some of the information needed to handle an exception is unavailable at the time of the throw. ----------------------------------------- Library: Bimap Author: Matias Capeletto Location: Boost Sandbox Vault Review Manager: Ion Gaztañaga Date: February 15 2007- February 25, 2007 Summary: With Boost.Bimap you can create associative containers where both types can be used as key. You can think a `bimap<X,Y>` as a merge of a `std::map<X,Y>` and a `std::map<Y,X>`. The learning curve of bimap is almost zero if you know how to use standard containers. A big effort was put in mapping the naming scheme of the STL in Boost.Bimap. The library is designed to match the STL common containers. ----------------------------------------- Library: Globally Unique Identifier Author: Andy Tompkins Location: Boost Sandbox Vault Review Manager: Needed Date: Needed Summary: A guid, or globally unique identifier, is an identifier standard used in many disciplines including computer networks, distributed computing, and databases. They can be used to tag objects with very short lifetimes, to reliably identify very persistent objects across a network. An attractive feature of guids is their relative small size, of 128-bits, compared to alternatives. Also the creation of guids does not require a centralized authority. ----------------------------------------- Library: Intrusive Containers Author: Ion Gaztañaga Location: Boost Sandbox Vault Review Manager: Joaquín Mª López Muñoz Date: March 1, 2007 - March 10, 2007 Summary: Existing practice have shown the need for intrusive containers. Widely used C++ libraries, such as C++ Standard Library and Boost have long missed such facilities so that users had to refrain from using those due to mandatory element copying or fall back to techniques like two phase construction to insert logically non-copyable elements in containers and initialize them after that or insert pointers to dynamically allocated objects which is rather inelegant and inefficient since containers also dynamically allocate nodes. The most common use cases for intrusive containers are, when one would like to store non-copyable elements in a container when it's beneficial to avoid needless data copy in performance critical applications. The most prominent example of both the use cases, although written for the most part in C rather than C++, is Linux kernel built solely upon intrusive lists, hash tables and trees. ----------------------------------------- Library: Scope Exit Author: Alexander Nasonov Location: Boost Sandbox Vault Review Manager: Needed Date: Needed Summary: The scope-exit-arg-pp-seq is Boot.Preprocessor sequence of identifiers that can be used inside scope-exit-body. The direct-declarator is declarator-id followed by optional argument of type boost::scope_exit_group (inside brackets or after the equal sign). This construct executes scope-exit-body at the close of the current scope. ----------------------------------------- Library: Finite State Machines Author: Andrey Semashev Location: Boost Sandbox Vault Review Manager: Needed Date: Needed Summary: The Boost.FSM library is an implementation of FSM (stands for Finite State Machine) programming concept. There are many cases when a developer would like to distinguish the behavior of a given object depending on some conditions or its internal state. For example, when making software to control an underground charging tourniquiet a programmer would like to separate states in which the tourniquiet may persist: an idle state, when the device awaits for another passenger that would like to pass; a processing state, when the passenger have come and put his ticket into the device; and the passing state, when the tourniquiet lets the passenger pass through. In fact, each state describes different reaction of the machine at the same events (a passenger may only pass after paying for ticket). Obviously, the tourniquiet have to be able to change its internal state in order to function properly, this is called state switching or transitions between states (or just transitions for short). ----------------------------------- Library: Statistical Distributions Author: John Maddock Location: Boost Sandbox Vault (math-toolkit) Review Manager: Needed Date: Needed Summary: Provides many of the tools required to implement mathematical special functions: hopefully the presence of these will encourage other authors to contribute more special function implementations in the future. There are helpers for the evaluation of infinite series, continued fractions and rational approximations. There is a fairly comprehensive set of root finding and function minimisation algorithms: both with and without derivative support. A Remez algorithm implementation allows for the locating of minimax rational approximations. There are also (experimental) classes for the manipulation of polynomials, for testing a special function against tabulated test data, and for the rapid generation of test data and/or data for output to an external graphing application. ----------------------------------- Library: Floating Point Utilities Author: Johan Råde Location: Boost Sandbox Vault http://boost-consulting.com/vault/index.php?directory=Math%20-%20Numerics Review Manager: Needed Date: Needed Summary: Proposed Additions to the Boost Math Library <boost/math/fpclassify.hpp> Functions for floating point number classification: fpclassify, isfinite, isinf, isnan, isnormal. Follows TR1. <boost/math/signbit.hpp> Functions for floating point number sign bit access and modification: signbit, copysign, changesign. Follows TR1. <boost/math/nonfinite_num_facets.hpp> Facets that parse and format infinity and NaN according to the C99 standard. Used for portable handling of infinity and NaN in text streams. ----------------------------------- Library: mcs::units Author: Matthias Schabel Location: Boost Sandbox Vault http://www.boost-consulting.org/vault/ (units) Review Manager: Needed Date: Needed Summary: mcs::units is a library providing zero-runtime overhead dimensional analysis for unit and quantity calculations. It provides support for 1) unit systems comprised of arbitrary sets of base units 2) arbitrary user-defined value types 3) support for heterogenous operator algebras (i.e. Z op(X,Y)) 4) support for basic outputting of quantities 5) optional support for implicit unit conversions It does not support 1) runtime units or quantities 2) input or parsing of quantities ----------------------------------- Library: Switch Author: Steven Watanabe Location: Boost Sandbox Vault http://tinyurl.com/yvssgx Review Manager: Needed Date: Needed Summary: Needed
