the problem about boost trim function in multi-thread
by Hu Jing 19 Jun '12

19 Jun '12

I use boost trim function and find it perform very well in single-thread environment. But when I call trim function in multi-thread environment, it will have a poor performance. I also find that it will have a good performance when call it using multi-process method. In the end, I write a simple trim function, it perform very well in multi-thread environment or multi-process environment. I think I must use it incorrectly in multi-thread environment. So I want to know what's wrong. Thanks for any reply. boost version: boost 1.46.1 os: linux redhat 6.1, 8core, 24G memory. the blow is sample code test1.cpp, call trim function in multi-thread environment //---------------------------- --------------------- using namespace std; using namespace boost; void *TrimNString(void *arg) { string base ="fdsffdsafdsa"; for(int i = 0; i != 50000000;i++) { string str = base; trim(str); } return 0; } int main() { //8 threads to call trim function system("date"); pthread_t mythread1, mythread2, mythread3, mythread4, mythread5, mythread6, mythread7,mythread8; pthread_create(&mythread1, NULL, TrimNString, NULL); pthread_create(&mythread2, NULL, TrimNString, NULL); pthread_create(&mythread3, NULL, TrimNString, NULL); pthread_create(&mythread4, NULL, TrimNString, NULL); pthread_create(&mythread5, NULL, TrimNString, NULL); pthread_create(&mythread6, NULL, TrimNString, NULL); pthread_create(&mythread7, NULL, TrimNString, NULL); pthread_create(&mythread8, NULL, TrimNString, NULL); pthread_join(mythread1, NULL); pthread_join(mythread2, NULL); pthread_join(mythread3, NULL); pthread_join(mythread4, NULL); pthread_join(mythread5, NULL); pthread_join(mythread6, NULL); pthread_join(mythread7, NULL); pthread_join(mythread8, NULL); system("date"); return 0; } test2.cpp, call trim function in multi-process environment //------------------------------------------------- /* * test.cpp * * Created on: 2012-6-19 * Author: root */ #include<pthread.h> #include <boost/algorithm/string.hpp> #include <string> #include <vector> #include <cstdlib> #include <iostream> using namespace std; using namespace boost; void *TrimNString(void *arg) { system("./TrimNString");// TrimNString is produced by test3.cpp return 0; } int main() { //8 process to call trim function system("date"); pthread_t mythread1, mythread2, mythread3, mythread4, mythread5, mythread6, mythread7,mythread8; pthread_create(&mythread1, NULL, TrimNString, NULL); pthread_create(&mythread2, NULL, TrimNString, NULL); pthread_create(&mythread3, NULL, TrimNString, NULL); pthread_create(&mythread4, NULL, TrimNString, NULL); pthread_create(&mythread5, NULL, TrimNString, NULL); pthread_create(&mythread6, NULL, TrimNString, NULL); pthread_create(&mythread7, NULL, TrimNString, NULL); pthread_create(&mythread8, NULL, TrimNString, NULL); pthread_join(mythread1, NULL); pthread_join(mythread2, NULL); pthread_join(mythread3, NULL); pthread_join(mythread4, NULL); pthread_join(mythread5, NULL); pthread_join(mythread6, NULL); pthread_join(mythread7, NULL); pthread_join(mythread8, NULL); system("date"); return 0; } test3.cpp, the executable file for test2.cpp /* * test.cpp * * Created on: 2012-6-19 * Author: root */ #include<pthread.h> #include <boost/algorithm/string.hpp> #include <string> #include <vector> #include <cstdlib> #include <iostream> using namespace std; using namespace boost; //produce the executable file int main() { string base ="fdsffdsafdsa"; for(int i = 0; i != 50000000;i++) { string str = base; trim(str); } return 0; } test4.cpp, call a simple trim(not boost library) function in multi-thread environment, it has similary performance like multi-process calling. //------------------------------------------------- #include<pthread.h> #include <boost/algorithm/string.hpp> #include <string> #include <vector> #include <cstdlib> #include <iostream> using namespace std; using namespace boost; void ltrim(string & str) { if(str.find_first_not_of(" \n\r\t") != string::npos) { str = str.substr(str.find_first_not_of(" \n\r\t")); } } void rtrim(string & str) { if(str.find_first_not_of(" \n\r\t") != string::npos) { str = str.substr(0, str.find_last_not_of(" \n\r\t") + 1); } } void trimStr(string &str) { ltrim(str); rtrim(str); } void *TrimNString(void *arg) { string base ="fdsffdsafdsa"; for(int i = 0; i != 50000000;i++) { string str = base; trimStr(str); } return 0; } int main() { //8 threads to call trim function system("date"); pthread_t mythread1, mythread2, mythread3, mythread4, mythread5, mythread6, mythread7,mythread8; pthread_create(&mythread1, NULL, TrimNString, NULL); pthread_create(&mythread2, NULL, TrimNString, NULL); pthread_create(&mythread3, NULL, TrimNString, NULL); pthread_create(&mythread4, NULL, TrimNString, NULL); pthread_create(&mythread5, NULL, TrimNString, NULL); pthread_create(&mythread6, NULL, TrimNString, NULL); pthread_create(&mythread7, NULL, TrimNString, NULL); pthread_create(&mythread8, NULL, TrimNString, NULL); pthread_join(mythread1, NULL); pthread_join(mythread2, NULL); pthread_join(mythread3, NULL); pthread_join(mythread4, NULL); pthread_join(mythread5, NULL); pthread_join(mythread6, NULL); pthread_join(mythread7, NULL); pthread_join(mythread8, NULL); system("date"); return 0; }

[test] long exception message and last checkpoint data
by Mathieu Champlon 19 Jun '12

19 Jun '12

Hi, I have a test case throwing a custom exception with a quite long error description. Because Boost.Test truncates it when translating the exception to a boost::execution_exception internally, only (about) 512 characters are being displayed. I suppose I could install a custom exception translator to perform the logging, then rethrow a boost::execution_aborted. However I don't see any way to access the last checkpoint data which are encapsulated and can only be logged by processing a boost::execution_exception within boost::unit_test::unit_test_log_t::exception_caught Is there anything obvious I have missed which could help me work around this issue ? Otherwise would this be a valuable feature request for the UTF ? Thank you, Mathieu

[Phoenix] boost::phoenix::erase crashes the app in VS2008
by Paul Heil 18 Jun '12

18 Jun '12

I have a Visual Studio 2008 C++03 application where I'm using boost::phoenix::erase (v1.49.0) on a std::list<int> container that does not contain the element I want to erase. This example is demonstrates the issue: int main() { namespace bp = boost::phoenix; namespace bpa = boost::phoenix::arg_names; std::list< int > a; // works as expected (does nothing) a.erase( a.end(), a.end() ); // fails a debug assertion "list erase iterator outside range" // Microsoft Visual Studio 9.0\VC\include\list\list : 790 bp::erase( bp::ref( a ), a.end() )(); return 0; } In release mode, this de-references an uninitialized pointer and the application crashes. Am I using boost::phoenix::erase correctly? Thanks

[iostreams] Possible bug in gzip_decompressor?
by Gavin Band 18 Jun '12

18 Jun '12

Dear list, I have been using boost.iostreams to read gzipped files for some time, but recently have run into some problems with files that are compressed using tools other than gzip (namely bgzip from http://samtools.svn.sourceforge.net/viewvc/samtools/trunk/samtools/). Here is the file: $ hexdump -C ../hello.txt.bgz 00000000 1f 8b 08 04 00 00 00 00 00 ff 06 00 42 43 02 00 |............BC..| 00000010 35 00 f3 48 cd c9 c9 d7 51 28 c9 c8 2c 56 00 a2 |5..H....Q(..,V..| 00000020 44 85 92 d4 e2 12 85 b4 cc 9c 54 3d 2e 00 86 1e |D.........T=....| 00000030 ef a4 1c 00 00 00 1f 8b 08 04 00 00 00 00 00 ff |................| 00000040 06 00 42 43 02 00 1b 00 03 00 00 00 00 00 00 00 |..BC............| 00000050 00 00 |..| 00000052 I think this is valid gzip format (based on reading http://www.gzip.org/zlib/rfc-gzip.html). It differs from what you get by compressing the file using the gzip program in two respects: 1. it uses the 'extra' flag (FLG.EXTRA) to add extra data to each block header, and 2. it has two blocks, the second of which is empty. My file reading code is as follows: /* test.cpp */ #include <iostream> #include <boost/iostreams/filtering_stream.hpp> #include <boost/iostreams/filter/gzip.hpp> #include <boost/iostreams/copy.hpp> #include <boost/iostreams/device/file.hpp> int main( int, char** ) { boost::iostreams::filtering_istream stream ; stream.push( boost::iostreams::gzip_decompressor() ) ; boost::iostreams::file_source file( argv[1] ) ; stream.push( file ) ; boost::iostreams::copy( stream, std::cout ) ; } I am using boost 1.48.0 on Ubuntu linux. The compilation is $ g++ -o test -g test.cpp -L /home/gav/Projects/Software/usr/lib -lboost_iostreams-gcc46-mt-1_48 -I /home/gav/Projects/Software/boost_1_48_0 Using gunzip on the above file works fine: $ gunzip -c ../hello.txt.bgz Hello, this is a test file. Using the test program does not: $ ./test ../hello.txt.bgz terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::iostreams::gzip_error> >' what(): gzip error I was able to fix this problem with two code changes in the boost.iostreams implementation, as follows. *Change #1*: at libs/iostreams/src/gzip.cpp:65: change "state_ = s_extra;" to "state_ = s_xlen;" Rationale: without this change, it looks like state s_xlen is never entered so the length of the extra data is not parsed. *Update:* I notice this change was already raised in ticket #5908, and has already been fixed in trunk. * * *Change #2*: at libs/iostreams/src/zlib.cpp:153: change "crc_imp_ = 0;" to "crc_ = crc_imp_ = 0;" Rationale: without this change, an empty block of data does not re-initialise the member variable crc_ of zlib_base. This causes an exception on line 447 of boost/iostreams/filter/gzip.hpp. I confirmed this behaviour a second way, by concatenating two files compressed using gzip, the first nonempty and the second empty. This creates a file which looks like this: $ hexdump -C hello2.txt.gz 00000000 1f 8b 08 00 0d ea b4 4f 00 03 cb 48 cd c9 c9 57 |.......O...H...W| 00000010 28 c9 48 2d 4a e5 02 00 8e 45 d1 59 0c 00 00 00 |(.H-J....E.Y....| 00000020 1f 8b 08 00 18 ea b4 4f 00 03 03 00 00 00 00 00 |.......O........| 00000030 00 00 00 00 |....| 00000034 This file again decompresses with gunzip but not with the program above. Change #2 above fixes this. Could someone take a look at this and let me know if this change is really appropriate? (Or perhaps I'm doing something wrong.) I can create a bug report if desired. Many thanks, Gavin Band.

Review Wizard Report for June 2012
by Ronald Garcia 18 Jun '12

18 Jun '12

============================================== Review Wizard Status Report for June 2012 ============================================== News ==== 1. Predef Library Reviewed 2. Boost 1.49.0 Released. New Library: Heaps 3. Multiprecision Arithmetic Review Ongoing Open Issues =========== The following libraries have been reviewed and await reports from their review managers: * Predef - reviewed February 2012; review manager: Joel Falcou. * Conversion - reviewed August 2011; review manager: Gordon Woodhull. The following libraries have been accepted to Boost, but have not yet been submitted to SVN: * Constrained Value - accepted September 2010; author: Robert Kawulak. * GIL.IO - accepted January 2011; author: Christian Henning. * Atomic - accepted July 2011; author Helge Bahmann. * Lockfree - accepted August 2011; author: Tim Blechmann. The following libraries have been accepted and submitted to SVN, but have not yet appeared in a release: * Type Traits Introspection - accepted August 2011; author: Edward Diener. * Context - accepted January 2012; author: Oliver Kowalke. The following libraries have been accepted provisionally to Boost, but have not been submitted for mini-review and full acceptance: * Endian - accepted provisionally November 2011; author: Beman Dawes. * Log - accepted provisionally March 2010; author: Andrey Semashev. General Announcements ===================== As always, we need experienced review managers. 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, including library contributors, infrastructure contributors, and other mailing list participants with a substantial track record of constructive participation. If you can serve as review manager for any of them, email Ron Garcia or John Phillips, "rxg at cs dot cmu dot edu" and "phillips at pacific dot 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. If you are interested in reviewing a library but won't have time during the review period, you can always prepare your review ahead of time. 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. The review schedule is an unordered list of the libraries awaiting review. As such, any library on the schedule can be reviewed once the developer is ready, a review manager has been secured, and the manager, developer, and wizards agree on a date to schedule the review. Review Schedule =============== * Join (M) * Pimpl (M) * Sorting (M) * Quaternions, Vectors, Matrices (M) * Variadic Macro Data (M) * Block Pointer (M) * Singularity (M) * Extended Complex Numbers (M) * Metaparse (M) * Polygon: Voronoi Extensions * Coroutine * Type Erasure * Range Extensions (M) * Contract * Nowide (M) ``(M)`` marks libraries that need review managers. -------------------- 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: https://github.com/boost-vault/Miscellaneous/blob/master/Pimpl.zip :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. Sorting ------- :Author: Steven Ross :Review Manager: Needed :Download: https://github.com/boost-vault/Sorting :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 2X as fast as std::sort, depending on processor, compiler optimizations, and data distribution. float_sort is roughly 70% faster than std::sort. string_sort is roughly 2X as fast as std::sort. Quaternions, Vectors, Matrices ------------------------------ :Author: Emil Dotchevski :Review Manager: Needed :Download: http://www.revergestudios.com/boost-qvm/ :Description: QVM defines a set of generic functions and operator overloads for working with quaternions, vectors and matrices of static size. The library also defines vector and matrix data types, however it allows users to introduce their own types by specializing the q_traits, v_traits and m_traits templates. Variadic Macro Data ------------------- :Author: Edward Diener :Review Manager: Needed :Download: `Boost Sandbox <http://svn.boost.org/svn/boost/sandbox/variadic_macro_data/>`__ :Description: This library adds support and functionality for variadic macros to Boost as well as integrating variadic macros with the Boost PP library without changing the latter library in any way. Block Pointer ------------- :Author: Phil Bouchard :Review Manager: Needed :Download: https://svn.boost.org/svn/boost/sandbox/block_ptr/ :Description: Deterministic memory manager of constant complexity capable of handling cyclic collections. Singularity ----------- :Author: Ben Robinson :Review Manager: Needed :Download: https://github.com/icaretaker/Singularity :Description: The Singularity Design Pattern allows you to restrict any class to a single instance. Unlike the infamous Singleton, Singularity gives you direct control over the lifetime of the object, does not require you to grant global access to the object, nor does it limit you to the default constructor for that object. Extended Complex Numbers ------------------------ :Author: Matthieu Schaller :Review Manager: Needed :Download: http://code.google.com/p/cpp-imaginary-numbers/ :Description: The library is an extension of the std::complex class addressing two issues: 1. The standard does not guaranty the behaviour of the complex class if instantiated with types other than float/double/long double. 2. Some calculation where pure imaginary numbers (i.e. multiples of sqrt(-1)) appear are unnecessarily slowed down due to the lack of support for these numbers. The code I submit contains two interleaved classes boost::complex and boost::imaginary which can be instantiated with any type T provided T overloads the usual arithmetic operators and some basic (real) mathematical functions depending on which complex function will be used. It is thus an extended version of Thorsten Ottosen's n1869 proposal (http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2005/n1869.html) Metaparse --------- :Author: Abel Sinkovics :Review Manager: Needed :Download: http://abel.web.elte.hu/metaparse/metaparse.zip :Description: Metaparse is a library for constructing parsers parsing at compile-time based on template metaprogramming. The parsers built with the library take boost::mpl::strings as input and can produce - types - objects (types with public static members) - callable C++ functions (types with public static method) - template metafunction classes as output (based on the input being parsed). On compilers supporting constexpr the library provides the following syntactic sugar for writing the input of the parsers: BOOST_STRING("this is a string") The library can be used for implementing DSLs in C++, including DSLs making C++ template metaprogramming easier (see examples). Polygon: Voronoi Extensions --------------------------- :Author: Andril Sydorchuk :Review Manager: Lucanus Simonson :Download: http://svn.boost.org/svn/boost/sandbox/gtl/ :Description: This library extends Boost.Polygon with the following features: - Robust and efficient implementation of the sweepline algorithm that allows to construct Voronoi diagram, Delaunay triangulation and medial axis of a set of points and line segments. - Coordinates of the output geometries are computed within the 64 machine epsilon relative error (6 mantissa bits). - Voronoi diagram data structure that allows efficient traversal and data association with the output Voronoi graph. - No 3rd party dependencies (e.g. GMP, MPFR), all the required multiple precision types are implemented as part of the library. - The input and output coordinate type domains are configurable via coordinate type traits, thus allowing to compute coordinates of the Voronoi vertices within any required precision. - The full construction of the Voronoi diagram of 100 000 points takes only 0.27 seconds (see benchmarks). Coroutine --------- :Author: Oliver Kowalke :Review Manager: Hartmut Kaiser :Download: http://gitorious.org/boost-dev/boost-dev/archive-tarball/coroutine :Description: This library is an implementation of coroutines and generators using Boost.Context. Type Erasure ------------ :Author: Steven Watanabe :Review Manager: Lorenzo Caminiti :Download: http://sourceforge.net/projects/steven-watanabe.u/files/ :Description: The TypeErasure library is a generalization of boost::any and boost::function. It allows easy composition of arbitrary type erased operators. Range Extensions ---------------- :Author: Akira Takahashi :Review Manager: Neil Groves :Download: https://github.com/faithandbrave/OvenToBoost :Description: This project adds some features of the Oven Range Library to Boost.Range. Features: - Additional Range Adaptors (taken, taken_while, dropped, dropped_while, elements, elements_key, memoized, outdirected) - Extensions for using Lambda (regular function, regular operator) - Infinite Range (iteration function) - and additional range utilities. Contract -------- :Author: Lorenzo Caminiti :Review Manager: Dave Abrahams :Download: http://sourceforge.net/projects/contractpp/files/latest/download :Description: This library implements Contract Programming for the C++ programming language (see the end of this email). In addition, the library implements virtual specifiers (final, override, and new, see C++11), concept checking, and named parameters. This library is implemented for the C++03 standard and it does not require C++11. Nowide ------ :Author: Artyom Beilis :Review Manager: Needed :Download: http://cppcms.com/files/nowide/ :Description: This library makes cross platform Unicode aware programming easier. It provides an implementation of standard C and C++ library functions, such that their inputs are UTF-8 aware on Windows without requiring to use Wide API. Libraries under development =========================== See http://svn.boost.org/trac/boost/wiki/LibrariesUnderConstruction for a current listing of libraries under development.

[boost] [review] Multiprecision review (June 8th - 17th, 2012)
by Jeffrey Lee Hellrung, Jr. 16 Jun '12

16 Jun '12

Okay, it's that time. Apologies for not sending a reminder, but there had been a lot of pre-review comments over the last week or so, so I think this has been on at least some people's radar. The original review announcement is given below. On Tue, May 29, 2012 at 2:08 PM, Jeffrey Lee Hellrung, Jr. < jeffrey.hellrung(a)gmail.com> wrote: > Hi all, > > The review of the proposed Boost.Multiprecision library authored by John > Maddock and Christopher Kormanyos has been scheduled for > > June 8th - June 17th, 2012 > > and will be managed by myself. > > From the Introduction: > > -------- > "The Multiprecision Library provides *User-defined* integer, rational and > floating-point C++ types which try to emulate as closely as practicable the > C++ built-in types, but provide for more range and precision.

As usual, please consider the following questions in your formal 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, most importantly, please explicitly answer the following question: Do you think the library should be accepted as a Boost library? Lastly, please consider that John and Christopher have compiled a TODO list [1] based on pre-review comments. Feel free to comment on the priority and necessity of such TODO items, and whether any might be show-stoppers or warrant conditional acceptance of the library. Thanks in advance; looking forward to the discussion! - Jeff (& John & Christopher) [1] http://svn.boost.org/svn/boost/sandbox/big_number/libs/multiprecision/doc/h…
