missing pthread_mutexattr_destroy in boost thread (V 1.31.0)
by Adrian 16 Mar '04

16 Mar '04

Dear William I think you have missed pthread_mutexattr_destroy() in recursive_mutex::recursive_mutex() and recursive_mutex::recursive_try_mutex(). Proposed patch: #elif defined(BOOST_HAS_PTHREADS) recursive_mutex::recursive_mutex() : m_count(0) # if !defined(BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE) , m_valid_id(false) # endif { pthread_mutexattr_t attr = 0; int res = 0; res = pthread_mutexattr_init(&attr); assert(res == 0); # if defined(BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE) res = pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE); assert(res == 0); # endif res = pthread_mutex_init(&m_mutex, &attr); pthread_mutexattr_destroy(&attr); /* missing */ if (res != 0) throw thread_resource_error(); ../.. recursive_try_mutex::recursive_try_mutex() : m_count(0) # if !defined(BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE) , m_valid_id(false) # endif { pthread_mutexattr_t attr = 0; int res = 0; res = pthread_mutexattr_init(&attr); assert(res == 0); # if defined(BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE) res = pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE); assert(res == 0); # endif res = pthread_mutex_init(&m_mutex, &attr); pthread_mutexattr_destroy(&attr); if (res != 0) throw thread_resource_error(); ___________________________________________________ Yahoo!

Though I was searching for the ability to just create a shared pointer anywhere and had it to any other DLL by exporting the entire shared pointer instantiation from the main DLL.

regex_iterator and sub_match
by Darren Cook 16 Mar '04

16 Mar '04

Hi, I finally upgrade to boost 1.31; as I got compile errors around the regex_grep stuff I decided to switch to regex_iterator. 1. It would be helpful if the top page of the docs had direct links to explanations of smatch and similar classes. 2. An example of how to use sub_match would be useful. The C++ parser example for regex_iterator is not ideal because: a) the regex is rather complex; b) the callback just uses str(), and never shows the type to use if you want to iterate through each character in the match. 3. I get this error (see P.S. for my code) `iterator' is not a member of type `boost::sub_match<__gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >' but this page says sub_match has an iterator type. libs/regex/doc/sub_match.html It compiles when I explicitly use std::string::const_iterator. Darren P.S. Cut down, my code looks like: bool parse(const boost::smatch::value_type &crd,const std::string &status){ //... boost::smatch::value_type::iterator p=crd.first; // <-- won't compile //std::string::const_iterator p=crd.first; // <-- compiles while(p<crd.second){ ... } //... } //In class Functor: bool operator()(const boost::match_results<std::string::const_iterator>& m){ //... bool ok=parse(m[1],m.str(2)); //... } std::string comment; //The string to parse boost::regex status_re("..."); Functor callback(...); boost::sregex_iterator m1(comment.begin(), comment.end(), status_re); boost::sregex_iterator m2; if(m1==m2)return 0; std::for_each(m1, m2, callback);

better nondeduced context workaround?
by Larry Evans 16 Mar '04

16 Mar '04

The following file: http://groups.yahoo.com/group/boost/files/cycle_basis_mgr.hpp forms part of an adaptation of policy_ptr to collect cycles in the pointer graph. Part of the difficulty was writing specializations for a curried class, e.g. template<typename ProxVisitor> class curry_prox_visitor_refcycle_counted { public: template <typename ReferentPtr> class owner ; }; due to the restrictions on "nested contexts" (see comments under namespace rm_nondeduced ). rm_nondeduced is part of a workaround, but I was wondering if there was a better way. I'm afraid I've missed some simpler way. Any help or advice appreciated.

[Boost-bugs] [ boost-Bugs-917070 ] Bug in lexical_cast.hpp

Bugs item #917070, was opened at 2004-03-15 21:44 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=917070&group_i… Category: lexical_cast Group: None Status: Open Resolution: None Priority: 5 Submitted By: John F Meinel Jr (jfmeinel) Assigned to: Kevlin Henney (kevlin) Summary: Bug in lexical_cast.hpp Initial Comment: In boost-1_31_0, I believe there is a typo in lexical_cast.hpp The line Target lexical_cast(Source arg) should be Target lexical_cast(Source& arg) Otherwise it actually creates a copy of the argument before doing the lexical cast. This causes problems if you try to lexical_cast() a virtual object. Here is code that shows the bug. By just adding the '&', the code performs as you would expect it to. #include <iostream> #include <string> #include <boost/lexical_cast.hpp> struct A { virtual int f() const = 0; }; struct B : A { virtual int f() const { return 1; } }; struct C : B { virtual int f() const { return 2; } }; std::ostream& operator<<(std::ostream& os, const A& a) { return os << a.f(); } int main() { C c; std::string s; std::cout << c << std::endl; //This should print 2 s = boost::lexical_cast<std::string>(c); std::cout << s << std::endl; //This should print 2 s = boost::lexical_cast<std::string, B>(c); std::cout << s << std::endl; //This returns 1, not 2 //This fails because it tries to instantiate an object of type A.

Proposal for a <stdfwd> header
by Javier Estrada 15 Mar '04

15 Mar '04

A couple of weeks ago I posted in c++ moderated: It seems natural that if there is a <iosfwd> to forward declare the I/O related classes, there should be a header for the classes contained in the std namespace. In the trenches, often times I come across classes that can be simply defined in terms of references and pointers to other classes. An example is defining interfaces or "protocol classes." Granted, with a small project, using an <stdfwd> header does not provide a big advantage, but I deal with 500+ files in a framework... I believe that the rationale is so simple that I even feel lazy about explaining the benefits, but oh well: // needlessly including the definition of string (or basic_string) and vector #include <string> #include <vector> class ISeek{ public: virtual void seek_knowledge(const std::string& token) = 0; virtual void seek_advice(const std::vector<std::string>& advisers) = 0; }; // using the proposed header... #include <stdfwd> class ISeek{ public: virtual void seek_knowledge(const std::string& token) = 0; virtual void seek_advice(const std::vector<std::string>& advisers) = 0; }; Please ready your darts and fire at will. I'd like to know if there is enough support that it could fly in a proposal to the std committee. Javier jestrada at developeer dot com

In my case I have a main DLL that is the brains of the entire app (the model is removed from the view and controller). I also have many other DLLs that are all dynamically loaded, and that can be unloaded at any time when they are no longer needed. These extra DLLs can "register" information with this main DLL, and then go away (sometimes this info is classes that are passed across DLL boundaries using shared pointers). These extra DLLs can also ask for information from the main DLL as well. The main DLL in my case never gets unloaded until the end (actually all other DLLs link to this main DLL), but all other DLLs can be unloaded. The main issue is the virtual function table, since when you pass off ownership of the shared pointer to another DLL, the code for that vtable lives within the contributing DLL, unless you explicitly instantiate it. I have no problem with the way shared_ptr's are currently implemented, I simply want to get them working with my program, and understand what I need to watch out and plan for. > > If DLL A has an STL container of shared pointers, and DLL B gets > > _dynamically_ loaded and adds an item to DLL A's container (creates > > a shared pointer to an object, and DLL B adds that shared pointer > > through an interface it to DLL A's STL container of shared > > pointers), DLL B can not be unloaded.

The idea of avoiding a combinatorial explosion through a single user-defined conversion metafunction which will be used to even the argument types is definitely solid; however, I am afraid we cannot escape with something as simplistic as conversion to a default predefined "contains-it-all" numeric type -- simply because there is no such type (for instance, 'fixed_c' is not capable of holding compile-time complex numbers, and so on). Moreover, specializing of arithmetic metafunctions is not necessary a prerogative of numeric types -- consider, for example, random-access iterators. To summarize, IMO the idea is excellent, but it needs to be carried a little bit further -- please see below. > 3) The conditional operations and 2 operand arithmetic operations > should be redefined in the base template definition to convert both > types to fixed_c and then make a comaprison, therefore allowing > programmers to use the operations on two different types of > compile-time constants without having to manually convert them to > similar types before-hand (as I alluded in first point).

Additional > suggestions are also greatly appreciated. You are going in the right direction. Here are some suggestions of how to generalize the scheme to get what I would consider an ideal solution: 1) Make specializable binary templates for each arithmetic/comparison metafunctions to be tag-dispatched metafunction classes, e.g. template< typename N1 , typename N2 > struct plus2 : plus_impl< // 'plus_impl' is a point of customization typename plus_tag<N1>::type , typename plus_tag<N2>::type >::template apply<N1,N2>::type { }; // 'plus_impl' implemenation for plain integral constants template<> struct plus_impl<integral_c_tag,integral_c_tag> { template< typename N1, typename N2 > struct apply : integral_c< BOOST_MPL_AUX_TYPEOF(N1,N1::value + N2::value) , (N1::value + N2::value) > { }; }; where 'plus_tag' is something as simple as template< typename T > struct plus_tag { typedef typename T::tag type; }; 2) Provide a rank mechanism so that we know in which direction to cast in case of mixed operations; can be as simple as an integral-constant 'rank' member of the corresponding tag: plus_tag< int_<5> >::type::rank == 0 3) Provide default implementations of '*_impl' binary templates which would use ranks, tags, and 'numeric_cast' to implement a general scheme for mixed arithmetics/comparison, something along these lines: template< bool c_ , typename Tag1 , typename Tag2 > struct plus_impl_ { template< typename N1, typename N2 > struct apply : plus_impl<Tag2,Tag2>::template apply< typename apply< numeric_cast<Tag2,Tag1>, N2>::type , N2 > { }; }; template< typename Tag1 , typename Tag2 > struct plus_impl_<false,Tag1,Tag2> { template< typename N1, typename N2 > struct apply : plus_impl<Tag1,Tag1>::template apply< N1 , typename apply< numeric_cast<Tag1,Tag2>, N2>::type > { }; }; template< typename Tag1 , typename Tag2 > struct plus_impl : plus_impl_< ( Tag1::rank < Tag2::rank ),Tag1,Tag2 > { }; Does it make any sense to you?

[circular buffer review]
by Thorsten Ottosen 14 Mar '04

14 Mar '04

Hi All, here is my review of the circular buffer class. What is your evaluation of the design? --------------------------------------- The design is good. People can easily learn to use it. There are some miner things that I would like see changed, like double versions of push_back and push_front. I don't understand why both set_capacit and resize are provided and I would like to see them merged if possible. I also think push_back should throw an exception if no element is inserted. This behavior is somewhat different push_back() from a normal std container. If there are similar cases then I think they should be looked at again too. What is your evaluation of the implementation? ----------------------------------------------- I haven't looked closely at the source code. What is your evaluation of the documentation? ---------------------------------------------- very good once the exception-safety issues are solved What is your evaluation of the potential usefulness of the library? ---------------------------------------------------------------- I'm in doubt. The library has efficiency as its hallmark. The rationale says that it gives efficient FIFO queue. So I tried to compare it with std::deque, and here is my results of an /O2 build with vc71: $ ./cbuffer_vs_deque.exe circular_buffer<int>: 2.15 s deque<int>: 2.84 s circular_buffer<string>: 20.59 s deque<string>: 18.64 s The test program is attached; I might have made an error, but if I have not, then I don't see the claim as true. In that case I need to see some more evidence about why the speed advantages should be so good. It also make me wonder if there is any need for circular_buffer_space_optimized. Did you try to use the library? With what compiler? Did you have any problems? ---------------------------------------------------------------------------- ------ yes, with vc7.1; Comeau 4.3.0 could not compile it. It worked fine on vc7.1 How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? ---------------------------------------------------------------------------- ------------------- A couple of hours with both documentation and code use. Are you knowledgeable about the problem domain? ----------------------------------------------------- I don't have experience with embedded applications; I have written stuff in which performace was critical and in which specially designed datastructures was necessary. Do you think the library should be accepted as a Boost library? --------------------------------------------------------------- Yes if the author can convince me that we really get more performance. No otherwise. best regards Thorsten begin 666 cbuffer_vs_deque.cpp M(V1E9FEN92!"3T]35%]$25-!0DQ%7T-"7T1%0E5'(#$-"@T*(VEN8VQU9&4@ M(F)O;W-T+V-I<F-U;&%R7V)U9F9E<BYH<' B#0HC:6YC;'5D92 \8F]O<W0O M<')O9W)E<W,N:'!P/@T*(VEN8VQU9&4@/&)O;W-T+W1H<F5A9"]T:')E860N M:'!P/@T*(VEN8VQU9&4@/&1E<75E/@T*(VEN8VQU9&4@/'-T<FEN9SX-"B-I M;F-L=61E(#QI;W-T<F5A;3X-"@T*=7-I;F<@;F%M97-P86-E(&)O;W-T.PT* M=7-I;F<@;F%M97-P86-E('-T9#L-"@T*;75T97@@<75E=65?;75T97@[#0IC M;VYS="!I;G0@<75E=65?<VEZ92 @(" @/2 U,# [#0IC;VYS="!I;G0@=&]T M86Q?96QE;65N=',@/2!Q=65U95]S:7IE("H@,3 P,# P.PT*#0IT96UP;&%T M93P@='EP96YA;64@475E=64@/@T*:6YL:6YE(&)O;VP@:7-?9G5L;"@@8V]N M<W0@475E=64F(&,@*0T*>PT*(" @(')E='5R;B!C+G-I>F4H*2 ]/2!Q=65U M95]S:7IE.PT*?0T*#0IT96UP;&%T93P@='EP96YA;64@475E=64@/@T*8VQA M<W,@<F5A9&5R#0I[#0H@(" @='EP961E9B!T>7!E;F%M92!1=65U93HZ=F%L M=65?='EP92!4.PT*(" @(%%U975E)B @<3L-"B @(" -"G!U8FQI8SH-"B @ M("!R96%D97(H(%%U975E)B!Q("D@.B!Q*'$I('L@?0T*(" @( T*(" @('9O M:60@;W!E<F%T;W(H*2@I#0H@(" @>PT*(" @(" @("!I;G0@<F5A9%]E;&5M M96YT<R ](# [#0H@(" @(" @( T*(" @(" @("!W:&EL92@@<F5A9%]E;&5M M96YT<R \('1O=&%L7V5L96UE;G1S("D@(" -"B @(" @(" @>PT*(" @(" @ M(" @(" @:68H("%Q+F5M<'1Y*"D@*2 @( T*(" @(" @(" @(" @>PT*(" @ M(" @(" @(" @(" @('L-"B @(" @(" @(" @(" @(" @(" @;75T97@Z.G-C M;W!E9%]L;V-K(&QO8VLH(&UU=&5X("D[#0H@(" @(" @(" @(" @(" @(" @ M(%0@=" ]('$N8F%C:R@I.PT*(" @(" @(" @(" @(" @(" @("!Q+G!O<%]B M86-K*"D[#0H@(" @(" @(" @(" @(" @?0T*(" @(" @(" @(" @(" @("LK M<F5A9%]E;&5M96YT<SL-"B @(" @(" @(" @('T-"B @(" @(" @(" @(&5L M<V4-"B @(" @(" @(" @(" @("!R96%D7W1H<F5A9"@I+3YY:65L9"@I.PT* M(" @(" @("!]#0H@(" @?0T*(" @( T*(" @('-T871I8R!T:')E860J)B!R M96%D7W1H<F5A9"@I#0H@(" @>PT*(" @(" @("!S=&%T:6,@=&AR96%D*B!T M(#T@,#L-"B @(" @(" @<F5T=7)N('0[#0H@(" @?0T*?3L-"@T*=&5M<&QA M=&4\('1Y<&5N86UE(%%U975E(#X-"F-L87-S('=R:71E<@T*>PT*(" @('1Y M<&5D968@='EP96YA;64(a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`` ` end
