[LibrariesUnderConstruction] new LibrariesUnderConstruction wiki page
by vicente.botet 07 Dec '08

07 Dec '08

Hi, I have created a new wiki page containing some of the libraries under construction for Boost. You can access this page from the Boost Trac wiki https://svn.boost.org/trac/boost/wiki > Projects > Libraries Under Construction or directly https://svn.boost.org/trac/boost/wiki/LibrariesUnderConstruction The contents of this page is by nature incomplete and outdated. Please help to maintain this page updated by modifying it directly (if you have the rights) or posting on the Boost mailing lists boost-AT-lists.boost.org or boost-users-AT-lists.boost.org with the prefix [LibrariesUnderConstruction]. If you're the author of one of these libraries and desire that all or part of the information related to your library be removed or modified, please send a mail or you can do it directly if you prefer. If you're a library author and plan on submitting a library but don't know when it will be ready for review, and you want to include your library in this list, please add it directly (if you have the rights) or send a mail. If you're a library author and plan on submitting a library for review in the next 3-6 months, email Ron Garcia or John Phillips ("garcia at osl dot iu dot edu" and "phillips at mps dot ohio-state dot edu" respectively) a short description of your library and they will add it to the Review Wizard Report Libraries Under Construction section. HTH, Vicente

Compiling Boost 1.36.0 for Itanium
by Amit Sonawane 07 Dec '08

07 Dec '08

Hi, I have the following environment: WinXP SP2/Visual Studio Team System 2005/Itanium cross compiler tools 1 . Generate boost libs using Itanium cross compiler command prompt with these options bjam -a --build-type=complete --toolset=msvc architecture=ia64 --stagedir=Winia64 stage 2. Compiling under Itanium configuration in VS2005 generates several linker errors as: error LNK2019: unresolved external symbol ._interlockedbittestandset referenced in function "[Entry] bool __cdecl boost::detail::win32::interlocked_bit_test_and_set(long *,long)" (.?interlocked_bit_test_and_set@win32@detail@boost@@YA_NPEAJJ@Z) error LNK2001: unresolved external symbol ._interlockedbittestandset 3.The projects compile fine under x86 and x64. _interlockbittestandset is not intrinsic on Itanium platform Has anyone come across this before ? or what is the correct way to build boost under itanium cross platform other then the options I used.

Threads and linking against the right Boost-libs
by Christoph Duelli 07 Dec '08

07 Dec '08

* When I have a program that use a second thread and only that second thread does use Boost, will I need to link against the "-mt" libs? (I am using linux.) [An example would be: when I use some Boost facilities together with Qt: Qt4 creates threads even if I do not use any explicitly.] * If I create a lib and that lib does not use threads, but does use Boost.Regex, I usually add a "-lboost_regex" to that lib. If a program later on uses both my lib and threads, would I have had to link against boost_regex-mt? Does this boil down to 'if I might use threads I should always link against the -mt libs'?

Re: [Boost-users] [review][constrained_value] Review of Constrained Value Library begins today

One idea on the dynamically changing the global bounds for a type as I keep mentioning, one concern people have is that it could invalidate instantiated objects of the type. As I said before, being able to dynamically change the bounds at runtime is essential, but most of the time you would do it before you instantiate anything. Hence, one solution is to make a check to see if it has been instantiated yet. I don't know enough metaprogramming to know if this is possible, but the idea is to flip some kind of a compile time flag in the constructor of the type and if you try to change the bounds after that, it fails a compile time assertion. So, the following would work: typedef bounded_type<double, "INTEREST RATE"> interest_rate; interest_rate::change_bounds(.8, .99); interest_rate r = .95; But the following would fail at compile time: typedef bounded_type<double, "INTEREST RATE"> interest_rate; interest_rate r = .95; interest_rate::change_bounds(.8, .99); If this is a good idea, my only request is a preprocessor instruction to turn it off... -Jesse

ublas vector resize std::bad_alloc
by Fabian Lim 06 Dec '08

06 Dec '08

Im having a memory management problem. I have 2 ublas vectors Vector A = vector<V1 > Vector B = vector<vector<V2 > > : first vector level size is 2^22 where the data types both V1=vector<int> and V2 are vector<vectors<int>> and the size |V1| <= 2 and the first level size of V2 <=2 and the second level size <= 10. A grows as my program runs. B also grows but only the second level. I run in windows and when i check the memory usage, it seems to be around 90,000K when the exception throws. I dont really have a good feel for these figures, so I compared to my firefox browser, which seems to occupy approximately the same amount of memory, hence i concluded that not alot of memory is used. My computers have around 1/2 Gb RAM. I do not see the typical OS slowdown which accompanies alot of paging.

boost::thread issue
by danielsabin＠comcast.net 05 Dec '08

05 Dec '08

Hi, I started working on a project a couple of months ago and i decided to use boost::thread. I like the library, very nicely done and easy to use - great job. However, I ran into an issue and although i have already spent a significant amount of time trying to figure it out, I was not able to make any progress so far. The project is written in pure C++ (no managed code) on Windows XP/SP3. I am using Visual Studio 2005 with SP1 as the C++ compiler. I am using the pre-built binaries for boost 1_36_0 provided by boost consulting. My main program simply creates several boost::thread objects which do various things. Everything works fine except for one thing: occasionally when I start the program I receive the following error: "The exception unknown software exception (0xc0000409) occurred in the application at location 0x00421cd3". In general exception 0xc0000409 means that the system detected (or thinks it detected) an overrun of a stack-based buffer. The code is compiled with the /GS switch (Buffer security check) enabled. The debug stack trace when the exception is thrown shows 2 threads, the exception being thrown by thread2, as follows: (thread 1) 5752 __tmainCRTStartup __CxxSetUnhandledExceptionFilter Normal 0 --------------------------------------------------------------------------------- ntdll.dll!_KiFastSystemCallRet@0() ntdll.dll!_ZwWaitForSingleObject@12() + 0xc bytes ntdll.dll!_RtlpWaitForCriticalSection@4() + 0x8c bytes ntdll.dll!_RtlEnterCriticalSection@4() + 0x46 bytes ntdll.dll!_LdrLockLoaderLock@12() + 0x6b bytes kernel32.dll!7c80b43f() [Frames below may be incorrect and/or missing, no symbols loaded for kernel32.dll] ntdll.dll!_ZwQueryVirtualMemory@24() + 0xc bytes kernel32.dll!7c80b9ed() kernel32.dll!7c8638bd() kernel32.dll!7c8449b0() ntdll.dll!_RtlpAllocateFromHeapLookaside@4() + 0x31 bytes kernel32.dll!7c80262a() ntdll.dll!_NtQueryInformationProcess@20() + 0xc bytes msvcr80.dll!7814a84c() MyService.exe!__CxxSetUnhandledExceptionFilter() Line 90 C++ msvcr80.dll!78131762() > MyService.exe!__tmainCRTStartup() Line 494 + 0xf bytes C kernel32.dll!7c817007() ntdll.dll!_RtlpAllocateFromHeapLookaside@4() + 0x31 bytes (thread 2) 7976 __report_gsfailure __report_gsfailure Time Critical 0 ------------------------------------------------------------------------- MyService.exe!__crt_debugger_hook() Unknown > MyService.exe!__report_gsfailure() Line 298 + 0x7 bytes C MyService.exe!boost::detail::create_once_mutex() + 0x63 bytes C++ MyService.exe!boost::call_once<void (*)(void)>() + 0x36 bytes C++ MyService.exe!boost::`anonymous namespace'::run_thread_exit_callbacks() + 0x34 bytes C++ MyService.exe!boost::thread::interrupt() + 0xdc bytes C++ ntdll.dll!_LdrpCallInitRoutine@16() + 0x14 bytes ntdll.dll!_LdrpCallTlsInitializers@8() + 0x12fad bytes ntdll.dll!_LdrShutdownThread@0() + 0xf4ae bytes kernel32.dll!7c80c0c6() [Frames below may be incorrect and/or missing, no symbols loaded for kernel32.dll] csauser.dll!10103b7f() kernel32.dll!7c80b6b9() Since I did not get too far on my own I really need your help.

[lambda] Can't quite get the hang of it!
by Robert Jones 05 Dec '08

05 Dec '08

Starting with this... for( j = joff; j < joff + 8; j++) for( i = ioff; i < ioff + 8; i++) img->m7[j][i] = iClip1(img->max_imgpel_value, (img->m7[j][i]+(long)mpr[j][i])); I'd like to move as much of the loop invariance out of the loop as I can. So I tried this... using boost :: lambda :: _1; using boost :: lambda :: _2; int ilast = ioff + 8; int jlast = joff + 8; boost :: function< int( int &, int ) > clip = _1 = boost :: lambda :: bind( iClip1, img -> max_imgpel_value, _1 + _2 ); for( j = joff; j != jlast; ++ j ) for( i = ioff; i != ilast; ++ i ) clip( img -> m7[j][i], mpr[j][i] ); Which works, but I'd like the nested clip function to be fn( i, j ), so I tried this... boost :: function< void( int, int ) > clip2 = boost :: lambda :: bind( clip, img -> m7[ _2 ][ _1 ], mpr[ _2 ][ _1 ] ); for( j = joff; j != jlast; ++ j ) for( i = ioff; i != ilast; ++ i ) clip2( i, j ); Which doesn't work. I think I need some boost::refs around the arrays I'm subscripting, but I can't quite seem to get it right. Error is... loop.cpp:50: error: no match for 'operator[]' in 'img->img_par::m7[boost::lambda::<unnamed>::_2]' loop.cpp:50: error: no match for 'operator[]' in 'mpr[boost::lambda::<unnamed>::_2]' loop.cpp:50: error: `bind' undeclared (first use this function) Any thoughts? Thanks, Rob.

shared_ptr to stack-allocated object
by Jason Cipriani 05 Dec '08

05 Dec '08

I'm refactoring parts of an existing application to use shared_ptrs instead of raw pointers. What is the best way to deal with code like this (please note in this situation passing a pointer to a stack-allocated object to function is acceptable and safe): void function (shared_ptr<Object> ptr) { ... } void function2 () { Object o; function(&o); // <--- need to change this } It seems I have two choices, I am not sure which is better, or if there are other common techniques. I can either use a no-op delete function: void noop (Object *) {} void function2 () { Object o; function(shared_ptr<Object>(&o, noop)); } Or I can allocate it on the heap instead of the stack, and let shared_ptr deal with the cleanup (this seems to be the more convenient solution): void function2 () { shared_ptr<Object> o(new Object); function(o); } What's the normal practice here? Thanks, Jason

Robert: >Sorry, but this makes no sense to me in the context of constrained values. If >the current bounds are [0, 1] and you have r1 == .5 and r2 == .9, then what >changing the bounds for the whole type to [.8, .99] would mean for r1?

Or the >bounds should change anyway, leaving the instance in invalid state? So what >would be the point of bounds checking, if you can't guarantee that once you >assign a valid value then the object will remain valid? The problem for me is that the change_bounds function at runtime operators on an instance rather than for the type itself (which is what the compile time bounds mean, and what I really want). I was using this as an example of why I believe the semantics are different and what I really want is something like what I listed next: >typedef bounded<double, "INTEREST RATE"> interest_rate; >typedef bounded<double, "RISK_AVERSION"> risk_aversion; >interest_rate r; >risk_aversion crra ; >change_bounds(r, .8. .99); //Statically change it >change_bounds(crra, .5, 10); //Statically. >interest_rate r_guess; //want the right bounds But even this is a little shady since I kept the change_bounds called on an instance to show the similarity to what is listed. What I would really be looking for is a way to change the bounds for the type itself, which would change static bounds. Maybe something like the following: >typedef bounded<double, "INTEREST RATE"> interest_rate; interest_rate::change_bounds(.8, .99); //Changes static data for the type? Does that help you make sense of my previous questions and comments? Now, you may say that this doesn't work because how could it throw errors on existing variables of type interest_rate that may not fulfill the bounds? The short answer is that it couldn't and it doesn't matter. In practice, you are changing the bounds here prior to creating instances of an item. It is purely a question of being able to dynamically create bounds for a type and then query them later... this makes the library far, far more than just a debugging and bounds checking utility and gives real semantics that can better match mathematics. >What you ask for is not possible in C++. You cannot have one type and use it >exactly the same way as other type. I'll give you some examples (having >constrained<string> cs): > const char * s = cs.c_str(); // not possible >Type constrained<string> can't have members that string has. > char c = cs[0]; // not possible Yes, I see now why it can't work for wrapping classes. But in my mind I am only thinking of the wrapping of intrinsic, built in types like doubles and ints. Here I would never want to call member functions on them... But it sounds like with no implicit conversions for template instantiation, we could run into problems... But how often would this be in practice? My knowledge of generic programming is not sufficient to understand the story here, but it sounds like the problem with std::max is that it is forcing the two parameters to be of the same type and that is the failure. Otherwise if std::max was written to take two different types with compatible comparison operators, that this could work fine? And if the constrained_value<double> had an implicit conversion to double, then we would have no problem? So is std::max anomalous here, and this wouldn't come up in practice for most usage for most numeric work? Thanks Robert. I really like this library and think it has great promise for those of us programming mathematics written on a blackboard.

noncopyable
by Hicham Mouline 05 Dec '08

05 Dec '08

AFAIU, deriving from boost::noncopyable disables _accidental_ object copying. Is it possible to implement a clone() const member function of the object to _explicitly_ get a copy of the object? Perhaps deriving boost::noncopyable makes it totally impossible to ever get a copy of an object without resorting to byte copy. Regards,

[asio] sending multiple messages in the same soocket
by Henrique Aparício 04 Dec '08

04 Dec '08

Hi! I'm trying to implement an asynchronous client to communicate with a server using asio. To do this, I'm following the example of the http client ( http://tenermerx.com/Asio/asio-1.3.1/src/examples/http/client/async_client.… http://tenermerx.com/Asio/asio-1.3.1/src/examples/http/client/async_client.… ), but I'm trying to make it so that it can be used for a more general purpose. So in my implementation I have the same methods that appear in the example, but with only one method for reading the response. My main function calls the constructor of the client which is responsible for initializing variables and calling the chain of asynchronous methods. After this, the main function calls a method send(message), that puts the message I want to send in the variable request and runs the io_service. The problem is that I want to be able to call this send function several times, but it only works the first time I call it. For example: Client c(host, port); //remember that the constructor calls the asynchronous methods c.send("msg to send"); c.send("msg to send"); The message is actually sent the first time, but the rest of the times nothing happens. What am I missing? Can you help me? If you need more information to be able to help, please ask me.

[multiindex] custom key extractor problem
by Stephan Menzel 04 Dec '08

04 Dec '08

Hi everyone, I could need a little advice using boost multiindex as follows: I have a Host class and I want to store HostPtrs in a multiindex container to a) have a member ip() as a key to unique hosts and b) be able to access random hosts via operator[]. The problem as I understand is the shared_ptr. Please consider this: class Host { public: Host(const boost::asio::ip::address &ip) : m_ip(ip) {}; const boost::asio::ip::address &ip(void) const throw () { return m_ip; }; private: Host(void) {}; boost::asio::ip::address m_ip; }; typedef boost::shared_ptr<Host> HostPtr; struct lthost { bool operator()(const HostPtr &h1, const HostPtr &h2) const { return (h1->ip() < h2->ip()); } }; struct giveip { // this is supposedly my key extractor typedef boost::asio::ip::address result_type; const result_type &operator()(const HostPtr &p) const { return p->ip(); }; }; typedef boost::multi_index_container< HostPtr, boost::multi_index::indexed_by< boost::multi_index::ordered_unique<giveip>, boost::multi_index::random_access<> > > HostSet; typedef HostSet::nth_index<0>::type HostSetOrderedIndex; typedef HostSet::nth_index<1>::type HostSetRandomIndex; Now inserting and accessing elements compiles fine, just when I try to erase something... int main(int argc, char **argv) { HostSet s; HostPtr p1(new Host(boost::asio::ip::address::from_string("127.0.0.1"))); HostPtr p2(new Host(boost::asio::ip::address::from_string("10.10.55.1"))); // now place a pointer to that host in the multiset. HostSetOrderedIndex &oi = s.get<0>(); oi.insert(p1); oi.insert(p2); oi.erase(p1); // booom } Basically, I want the index to access each ptr's ip() function to get the key rather than the ptr itself, which would be just random mem as far as I understand it. So the key extractor should work, shouldn't it? I also tried the lthost() function: typedef boost::multi_index_container< HostPtr, boost::multi_index::indexed_by< boost::multi_index::ordered_unique<boost::multi_index::identity<HostPtr>, lthost>, boost::multi_index::random_access<> > > But that doesn't work either. I guess it's accessing the HostPtr directly instead of dereferencing it. It does compile and also does the job but tests have shown that when I do this: HostSetOrderedIndex &oi = s.get<0>(); oi.insert(p2); HostSetRandomIndex &hsri = s.get<1>(); hsri.sort(); and then iterate over the container (hsri) the order will vary. Sometimes one of the hosts appears at [0] sometimes the other. I'm quite puzzled how this is supposed to work. Can you give me some hints?? Thanks a lot, Stephan PS: I know, the use case is kinda weird. Basically, I want to be able to insert elements with the set logic, and only the IP shall count as identity. Access via random access index is necessary to do hashing in a stable deterministic way over the container.

Re: [Boost-users] [review][constrained_value] Review of Constrained Value Library begins today
by Robert Kawulak 04 Dec '08

Hi Jesse, From: "Jesse Perla" >4. If it is true in general, then this statement: >http://student.agh.edu.pl/~kawulak/constrained_value/constrained_value/ >rationale.html#constrained_value.rationale.no_floats >makes this library practically useless. This is the problem of limited usefulness of built-in floating point arithmetic rather than of this library. If you need constrained floats, use a library for reliable, repeatable floating-point computations. >typedef bounded<double> interest_rate; >interest_rate r1, r2; >change_bounds(r1, .8, .99); > >Now the interest rate bounds on r2 don't exist, right? This is a big >problem for me... It would mean that the bounds information is not kept on >the type, but on the instantiation... Sorry, but this makes no sense to me in the context of constrained values. If the current bounds are [0, 1] and you have r1 == .5 and r2 == .9, then what changing the bounds for the whole type to [.8, .99] would mean for r1? How the type is supposed to know that there is an instance that is not valid according to the new bounds? The type should keep handles to all its instances? Or the bounds should change anyway, leaving the instance in invalid state? So what would be the point of bounds checking, if you can't guarantee that once you assign a valid value then the object will remain valid? >6) Is there any way to get the library to compile: std::max(2, i) instead of >using i.value() as mentioned in the tutorial for a constrained i? No. These are just the rules for template functions. Implicit conversions are not taken into consideration in such case, so both the arguments have to be of identical type. >This >really is essential to make the library equivalent to normal operations, but >with extra type information. Again, I am willing to forgo ease of use on >the bounds checking for this... What I really want is the instantiation to >behave EXACTLY the same as an underlying type. So overloading the ++, +, >etc. are useful, but I would go further to say that perhaps everything could >be done by just going back to the underlying type... What you ask for is not possible in C++. You cannot have one type and use it exactly the same way as other type. I'll give you some examples (having constrained<string> cs): const char * s = cs.c_str(); // not possible Type constrained<string> can't have members that string has. char c = cs[0]; // not possible Type constrained<string> can't have operators that string has. How would you define such operator for constrained class template? How would you know what should be its return type in general case (without decltype available, of course)? Best regards, Robert

Hello everybody, I have a question on ublas::compressed_matrix. I need to build a submatrix of a compressed_matrix. This should also be a compressed_matrix composed out of different rows of the original matrix. I have a std::set containing all row-indicis of the original matrix rows the submatrix should contain. Here is my problem, I can't find a way to do this. I know that there is a way to get rows out of a matrix. But these are dense rows -> too much unneeded data (Is there a way to insert complete rows at all?). Is there a way to copy a row of a compressed_matrix as compressed_vector and insert the vector in another compressed_matrix? I also thought about extracting only the values!=0 of the individual rows like here: http://guwi17.de/ublas/matrix_sparse_usage.html but I don't want to iterate over all rows and test if the set contains the rowindex. It would be very nice, if someone could give me a hint how to solve this problem. Thanks and regards Bastian

Unable to use boost libraries with xcode 3.1
by framebuffer 04 Dec '08

04 Dec '08

Hi! I am using xcode 3.1 and I am trying to build a 32bit boost test application. I have done this successfully on windows (Header only libraries are working fine in xcode). These are the steps I followed: 1) ./configure --with-libraries=date_time,filesystem,iostreams,program_options,serialization,system,thread 2) sudo make install I dont get any error and the installation says it updated all targets. 3) Next, I create a simple thread application to test: #include <boost/thread/thread.hpp> #include <iostream> void hello() { std::cout <<"Hello world, I'm a thread!"<< std::endl; } int main(int argc, char* argv[]) { boost::thread myThread(&hello); myThread.join(); return 0; } 4) I go to project > edit project settings and add the following two paths in the search path section: /usr/local/lib (for library path) and /usr/local/include/boost-1_37 for header path. BOOST_ROOT is set as /Users/Framebuffer/boost_1_37_0 I have even tried to change it to /usr/local/ but the errors persist I have examined the two folders and the libraries and headers are indeed present there (for eg, libboost_thread-xgcc40-mt-1_37.dylib is in the lib folder) 5) When I try to compile either the debug or release version, I get errors.

boost asio async_read_some
by Chris Freehill 04 Dec '08

04 Dec '08

Hi, I've been struggling for a while trying to get async_read_some() to call the handler I provided, but it never seems to happen. However, the buffer provided does seem to be written with the expected data from the tcp/ip socket I'm using. Here's a simplified version of my call and handler: unsigned char tmpBuffer[512]; //global void MyClass::handler(const boost::system::error_code& error, size_t bytes_transferred) { boost::system::error_code e; std::cerr << "handler called()" << "\n"; } void MyClass::test() { ... socketPtr->async_read_some(boost::asio::buffer(tmpBuffer, 512), boost::bind(&MyClass::handler, this, boost::asio::placeholders::error, boost::asio::placeholders::bytes_transferred)); } Can anyone give me any idea as to how I can get my handler to be called? The other thing worth mentioning is that if I use read_some() instead, I get the expected data. In the documentation for this method (see link below), http://www.boost.org/doc/libs/1_37_0/doc/html/boost_asio/reference/basic_st… there is the comment "Regardless of whether the asynchronous operation completes immediately or not, the handler will not be invoked from within this function. Invocation of the handler will be performed in a manner equivalent to using boost::asio::io_service::post()." I'm not sure exactly what this means...what is this equivalent manner that is mentioned? Thanks, Chris

If we take a constraint representing a percentage between 0 and 100, I think it is perfectly valid to add a percent to what is already there. That is just one of innumerable cases where arithmetic operations of contraints seem perfectly valid to me. Why would you even want to consider limiting constraints by removing arithmetic operations if the underlying type supports such operations ? _______________________________________________ Boost-users mailing list Boost-users(a)lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users Sent from my Verizon Wireless BlackBerry

Suppose the value is provided by the end user of the program. Do you still feel such a value, when used in a constraint, should assert only in debug mode rather than throw an exception ? A large part of the constrained value concept is that the constraint provides the necessary checking, in the form of a policy, which alleviates specific pre-checking by the programmer. I like that, else the constraint library serves less purpose than it could. _______________________________________________ Boost-users mailing list Boost-users(a)lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users Sent from my Verizon Wireless BlackBerry

How to pass a shared_ptr to a thread.
by Jason Cipriani 04 Dec '08

04 Dec '08

Hi, I'm new to boost. I'm using it for the shared_ptr implementation. I have a usage question. On Windows, a thread function takes a void* parameter. If I have a shared_ptr to an object, what's the correct way to pass that to a new thread? E.g.: DWORD WINAPI threadproc (LPVOID something) { // how to get a shared_ptr through "something"? ... } void create5threads () { ... shared_ptr p(new Object); // what should "something" be if i want to pass p to the new threads, incrementing its use count? CreateThread(..., &threadproc, (LPVOID)something, ...); CreateThread(..., &threadproc, (LPVOID)something, ...); CreateThread(..., &threadproc, (LPVOID)something, ...); CreateThread(..., &threadproc, (LPVOID)something, ...); CreateThread(..., &threadproc, (LPVOID)something, ...); } Sorry if this is a stupid question, but the only thing I could think of was "(LPVOID)new shared_ptr(p)", but that means each thread must explicitly delete the new shared_ptr and that kind of defeats the purpose! Thanks, Jason

Questions about Program_options
by Yang Zhang 03 Dec '08

03 Dec '08

Hi, I'm currently enjoying using Program_options, and I have a few questions/comments about it. Is it necessary to create and use a variable_map for parsing program options? Is there a way to forgo this if I've already used value<T>(T*) to bind the options to other storage locations? What is notify() for, exactly? This is not really described in the documentation. It may be worth mentioning bool_switch somewhere in the documentation. (I dug this up from the header files.) Can I access positional arguments without going through the positional_options_description? My program is "variadic" and takes either 1 or 2 arguments (where the first has a completely different meaning depending on the number of args). I realize I can assign meaningless names in the positional_options_description, like "arg0," "arg1," etc., but I'm just wondering if there's already a way to access the raw positional arguments without going through the positional_options_description boilerplate. Is there a way to specify a *hierarchy* of command-line parameters, such as those found in svn (a two-layer hierarchy), git, etc.? If not, consider this a feature request! In svn, for instance, there are global options, there's the exact command, and then there are sub-options associated with the command. See the Python argparse module for an example of such a library design: http://argparse.python-hosting.com/ Thanks in advance for any answers. -- Yang Zhang http://www.mit.edu/~y_z/

But this is just a straightforward example. Other example: There is a tool that is compiled on Windows and Linux. It does not have argc, argv because command line is entered say in editbox. The tool should parse this line and the algorithm should be the same in all operating systems to have single behavior. In my case the user specifies a command line as an argument to a function in script file. Probably it is safe to allow using split_winmain in UNIX to avoid the hell described in previous message.

path separator char/string
by boost001 03 Dec '08

03 Dec '08

I need to get the char or string represent current system's path separator. In ACE , we can get from this constant: ACE_DIRECTORY_SEPARATOR_CHAR. Does Boost has the similar constant to do the same? I looked at the path.hpp. I think maybe I can get it from the following existing code: 1. template<class Path> struct slash { BOOST_STATIC_CONSTANT( char, value = '/' ); }; 2. # ifdef BOOST_WINDOWS_PATH template<class Path> struct path_alt_separator { BOOST_STATIC_CONSTANT( char, value = '\\' ); }; # endif 3. template<class Path> inline bool is_separator( typename Path::string_type::value_type c ) { return c == slash<Path>::value # ifdef BOOST_WINDOWS_PATH || c == path_alt_separator<Path>::value # endif ; } But I don't know exactly how. Anybody can help me? -- View this message in context: http://www.nabble.com/path-separator-char-string-tp20820786p20820786.html Sent from the Boost - Users mailing list archive at Nabble.com.

[boost][serialization] void_upcast is very slow
by Jacob 03 Dec '08

03 Dec '08

The original "inline void_upcast" method checks if the pointer to the object is of the right type, by traversing its parents. This is necessary when using multiple inheritance, since in such a case the adress of the pointer to the object can vary depending on which base class it is cast to. While profiling one of my projects I noticed that most of the time was spent in the void_upcast method. I modified the method to return the pointer directly(see below), resulting in a high performance increase. This "solution" is possible if you avoid multiple inheritance all together, which I did. In my particular project I experienced a 75% speed increase implementing this, going from about 10 seconds to 2.5 seconds. Would it be possible to implement some functionality to turn on and off the upcasting for given classes, kind of like the tracking of objects is currently administrated? Modified "inline void_upcast": /inline void * void_upcast( extended_type_info const & derived, extended_type_info const & base, void * const t ){ return const_cast<void*>(t); }/ Yours sincerely, Jacob Holm

Re: [Boost-users] Turn off versioning in Serialization

Robert, Thanks for the quick reply. I was able to turn all the headers off but there is still one number (which seems to be thre string length) that I can not turn off. If this is unable to be turned off then I will proceed to the Case Study you mentioned. Brian Brian Nantz wrote: > I am using serialization split member (save & load) and it works > great.

Re: [Boost-users] [review][constrained_value] Review of Constrained Value Library begins today
by Jesse Perla 03 Dec '08

03 Dec '08

As someone who was about to try to write something similar out of necessity, let me throw out a few practical considerations and a use case. These are a wish list from a library user that is not a generic library programmer: What I really want is to have a "type" that contains bounds information, rather than for bounds checking itself (which is gravy). And I want to use this for pretty functional programming, and see this as an incredibly useful library and integral to taking C++ to the next level for programming mathematics. I do not see this as primarily an equivalence to units, though I understand that use case. My primary cases for this are: 1. For functors that contain domain/range sets to match the blackboard mathematics I am implementing in code. Including "operators" that map functors to functors (my main case being a derivative operator or a conditional expectation). 2. To use this an optimizer framework. The problem is that you end up having to keep around lists of reasonable bounds on what values the optimizer should be allowed to use. But this information becomes separated from the real "type" of the variable, even though that is where it conceptually belongs. And when you call optimizers you need to have both. Of course, this optimizer/root finder problem is really the same issue as maintaining range/domain for functors. So a few comments on what I would love to be able to do to support this: 1. The closed/open bounds in here is necessary, especially for optimizers where you frequently have asymptotes at the bounds (virtually always in the dynamic programming for economics problems I work with). 2. I would go further than saying that the closed/open bounds is a starting point and that the library should ultimately be designed to accomodate (runtime) unions of intervals and discrete points i.e. [x,x] in intervals. This would be very useful for game theory applications where you could get non-connected sets of equilibrium conditions. Or functions where you can have asymptotes in the middle that are not defined, but it is defined on both sides. Last, would be nice to allow for a discrete set of real values as bounds. If the design of the library could support this (maybe by returning an iterator over the ranges if necessary?) then it could be implemented later. Keep in mind that my need is to access/set the bounds at runtime rather than just boundschecking by writing my own bounds checking predicate. 3. Turning off the bounds-checking at runtime could be useful (though certinaly not through NDEBUG!), but you would NEVER want to turn off the availability of the bounds information at runtime since that is the core usefulness of the library. 4. If it is true in general, then this statement: http://student.agh.edu.pl/~kawulak/constrained_value/constrained_value/rati… makes this library practically useless. I understand the rationale, but since all optimizers take floats or doubles, and 99% of functions map doubles to doubles for me, this is an unreasonable constraint. If the problem here is just for the bounds checking, then I am not worried since I really want type information. 5. Sometimes you want to have compile-time fixed bounds , other times modifiable at runtime. So I like this, but they need to behave the same way. But what I really want to do is change the bounds of the type itself at runtime, not just the bounds on an individual instantiation. See the following to see if I am misundertanding the library: typedef bounded<double> interest_rate; interest_rate r1, r2; change_bounds(r1, .8, .99); Now the interest rate bounds on r2 don't exist, right? This is a big problem for me... It would mean that the bounds information is not kept on the type, but on the instantiation... this has extra data and has completely different semantics from the static bounds case where it really is associated with the type. What I would really want is some kind of static data associated with the type. I understand the difficulty here, but nevertheless this is the main usefulness of the library. I also note that this means the "typedef" approach may be a problem as it is set up since the library would have no way to tell the difference between these types to store static bounds, even though this is exactly what I want.: typedef bounded<double> interest_rate; typedef bounded<double> risk_aversion; interest_rate r; risk_aversion crra ; change_bounds(r, .8. .99); //Storing this statically change_bounds(crra, 1.0, 10.0); //Statically. interest_rate r_guess; //Want the right bounds! Can't exist here? Of course, with static bounds this kind of thing works. Perhaps it is reasonable to throw in some sort of useless trick for the compiler to separate when storing static data to keep semantics with the static bounds the same? I don't know if this is a good approach, but it would be reasonable to ask of library users: typedef bounded<double, "INTEREST RATE"> interest_rate; //In fact, I wouldn't even mind having the "name" available at runtime for pretty_printing... typedef bounded<double, "RISK_AVERSION"> risk_aversion; interest_rate r; risk_aversion crra ; change_bounds(r, .8. .99); //Storing this statically, now the two types are distinct? change_bounds(crra, .5, 10); //Statically. interest_rate r_guess; //Want the right bounds. Naturally, there are other cases where you might want to change the bounds on an instantiation. If both could be supported (and returned through the same bounds function, modified through different ones) that would be nice, but the above use case is far more important to me. 6) Is there any way to get the library to compile: std::max(2, i) instead of using i.value() as mentioned in the tutorial for a constrained i? This really is essential to make the library equivalent to normal operations, but with extra type information. Again, I am willing to forgo ease of use on the bounds checking for this... What I really want is the instantiation to behave EXACTLY the same as an underlying type. So overloading the ++, +, etc. are useful, but I would go further to say that perhaps everything could be done by just going back to the underlying type... with abolutely no overhead since it would make this useless for numeric programming. If I multiply or add these kinds of values, I would want the result to be of the underlying type and don't care about the mechanics of ensuring that the result type is bounded itself, etc. I can construct my own bounded type for the return type if I have to... Thanks for listening. And if people have better ideas of a framework or approach to do this kind of stuff, please tell me. I may be stretching the expectations of this library... -Jesse

[Thread] barrier destruction after wait() results in assertion
by Peter Klotz 03 Dec '08

03 Dec '08

Boost 1.37.0, Red Hat Enterprise Linux 5 x86_64, gcc 4.1: The following simple test establishes a barrier with thread count 2. One of the threads destroys the barrier after returning from wait(). This results in sporadic assertions from ~mutex(). boost/thread/pthread/mutex.hpp:45: boost::mutex::~mutex(): Assertion `!pthread_mutex_destroy(&m)' failed. #1 0x00000038306295d6 in __assert_fail () from /lib64/libc.so.6 #2 0x000000000040245a in ~mutex (this=0x1f63f010) at boost/thread/pthread/mutex.hpp:45 #3 0x0000000000402488 in ~barrier (this=0x1f63f010) at boost/thread/barrier.hpp:24 I assume that this usage of barrier is not supported/allowed. One cannot assume that the barrier can be destroyed just because the corresponding thread returned from wait(). Is this conclusion correct? Regards, Peter. #include <boost/scoped_ptr.hpp> #include <boost/thread/barrier.hpp> #include <boost/thread/thread.hpp> boost::scoped_ptr<boost::barrier> barrier; void f() { barrier->wait(); } int main(void) { barrier.reset(new boost::barrier(2)); boost::thread thread(boost::bind(&f)); barrier->wait(); barrier.reset(); thread.join(); return 0; }

Threads - Access in invalid memory Boost 1.36.0 BCB 5.8.3
by Stephen Kierzewski 03 Dec '08

03 Dec '08

Hello, I have a simple OpenGL program that is using Boost Threads and I had it working fine under Boost 1.34. I have switched to 1.36 for some of the newer mutex locking functionality and everything works fine, but.. I keep getting an invalid memory access error. My program will run fine if i skip past the offending call. Wondering if anyone has any ideas? The offending call happens when the rendering thread is created. The call stack is as follows: Access in invalid memory in process: solarsystemT.exe(4056) - :\development\boost_1_36_0\boost/thread/win32/once.hpp#125 Attempt to access 4 byte(s) at 0x00417084. 0x00411056 - E:\development\boost_1_36_0\boost/thread/win32/once.hpp#125 0x0041137B - E:\development\boost_1_36_0\libs\thread\src\win32\thread.cpp#44 0x00411A61 - E:\development\boost_1_36_0\libs\thread\src\win32\thread.cpp#151 The memory that boost::call_once is accessing is current_thread_tls_init_flag created earlier by boost::once_flag current_thread_tls_init_flag=BOOST_ONCE_INIT; I can see that this flag was created and initialized to zero. Thank you for any insight. Stephen Kierzewski

Boost.Build newbie
by frederic.bron＠alcan.com 03 Dec '08

03 Dec '08

I have read the documentation of boost.build on boost.org and I have a few questions: 1.) I do not understand what's more in boost.build compared to bjam; I see no reference to something else than bjam in boost.build doc. 2.) Is it true that the dependencies must be specified manually in a Jamfile; dependenceis are not automatically found with header files. I understood this from this page of the doc : http://www.boost.org/doc/tools/build/doc/html/bbv2/tutorial/libs.html However, the example is with a library dependency and not with source file dependecies. Today I use the makedepend utility and a bash script to build a valid Makefile. However, it is hard to maintain and I would like to add msvc compiler on windows and it causes me much trouble. Boost.build seems to do that but if I have to manually track the dependencies, I prefer to continue with gcc only. Regards, F.

how to work with shared pointers to avoid clumsiness
by Roman Shmelev 03 Dec '08

03 Dec '08

Hi, I've tried to read boost docs and some forums but still cannot understand how to make things simple and right. 1) I have an object that is dynamically allocated and I want it to delete itself (so I understood I need to use shared_ptr) 2) The object must be deleted not after the last shared_pointer to it will be destroyed, because some external functions will call it later one more time. And then it must be destroyed. 3) Of course, that external functions cannot accept shared_ptrs. 4) So, I need my object to know when all shared_ptrs to it are destroyed. Then it sets some flag (I_CAN_DESTROY_MYSELF_SOON) and when some external code (that holds simple pointer to this object) will call its function, then it will destroy itself. How to solve this in an elegant way? I'm currently do not use shared_ptr, but my implementation is cumbersome. Maybe I need one more shared_ptr inside the object.. I don't know. Thank you.

[program_options]
by Vitaly Grechko 03 Dec '08

03 Dec '08

Could _WIN32 be removed from program_options\parsers.hpp? There is no way in UNIX to parse command line independently from string. To use the library I had to dublicate parsers.hpp and winmain.cpp files localy with _WIN32 removed, which is ugly. Before this I tryed to define _WIN32 before including parsers.hpp and undef after - this affected other boost headers and did not compile. I don't see the reason to have _WIN32 macro there because the code is just an algorithm and complied successfuly in all platforms. The meaning of the algorithm is in the name of the function 'split_winmain(...)'. The use case example: command lines from Windows client machines go to Unix server for validation and logging. In this case split_winmain is regularly used on UNIX Vitaly

polymorphic archive use and memory leak
by sam p 03 Dec '08

03 Dec '08

Hi, I am using polymorphic archive in my code and I am using it as follows, 1 void func(std::stringstream &ss, boost::archive::polymorphic_oarchive *&ptr) 2 { 3 ptr = new boost::archive::polymorphic_text_oarchive(ss); 4 return; 5 } 6 int main() 7 { 8 std::stringstream ss; 9 boost::archive::polymorphic_oarchive *ptr = NULL; 10 func(ss, ptr); 11 delete ptr; //Will this delete object properly????? 12 } Now the question is, whether 'delete' one line no. 11 will work properly or not? And is this a right way to use polymorphic archive? Thanks, Sameer

I could do that but an accidental inclusion of a header file that tries to implicitly link to a boost library would fail. I will know the reason but my fellow developers will start analyzing the problem that I want to avoid. I chatted on #boost and decided to use the following batch file to get the header only part from BOOST (it can be a shell script too): I put the following lines in a batch file (M$) and pass the bjam build options like prefix or layout: @SET BOPT= @FOR /F "skip=1 tokens=2" %%a in ('bjam --show-libraries') do @SET BOPT=!BOPT! --without-%%a @ECHO bjam %* %BOPT% The output (with install appended) is the command to extract and install the header only part. -dhruva -- Contents reflect my personal views only!

Hi, I am trying to use Boost::Filesystem to copy files to and from a mapped network drive e.g. X:\SomeFolder. When trying to do this boost::filesystem does not recognise it as a valid folder. It fails exists and is_directory. I have also tried using system_complete to see if this would generate me a valid path, unfortunately not. I am using WindowsXP and i'm wondering if anyone has run into a similar problem? or if there is a concrete reason why the mapped drive is not recognised as a valid folder. thanks Conrad Mercer --

[announce][flyweight] Boost.Flyweight added to the trunk
by JOAQUIN M. LOPEZ MUÑOZ 02 Dec '08

02 Dec '08

Hello, I'm happy to announce that Boost.Flyweight has been just commited to the SVN trunk, far too many months later than initially planned (but better later than never). The goal is to have the lib included in Boost 1.38, if its stability and the release manager permit. If you're interested in the Boost.Flyweight please update your SVN copy, play with the lib and report your comments/complaints. Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

boost 1.34 supports asio or not?
by boost001 02 Dec '08

02 Dec '08

Anybody can tell me Boost 1.34 include asio package or not? My machine has an installed 1.34 version of boost. The existing code compile and link on 1.34 has no problem but cannot link on 1.37. So want to start from 1.34 and then move to 1.37. Need to know if ASIO was in 1.34 or not. thanks, -- View this message in context: http://www.nabble.com/boost-1.34-supports-asio-or-not--tp20799239p20799239.… Sent from the Boost - Users mailing list archive at Nabble.com.

[iostreams] mapped_file_source and std::ios::in
by Norbert Wenzel 02 Dec '08

02 Dec '08

Hi, I've recently been reworking some filereaders and changed them from std::iostream to boost::iostreams::mapped_file_source. Though the data has been fully loaded the std::getline() did set only the first character of the text and returned false, which caused the usual while loop to exit. When I wanted to ask you for help and made up a small example, in which the filereading - to my surprise - worked fine. The problem has been, that from rewritting from the code from std::iostreams there was an std::ios::in left. So my actual filereading looked like this: io::mapped_file_source file("C://test.txt", std::ios::in); io::stream<io::mapped_file_source> input(file); std::string line; while(std::getline(input, line)) { std::cout << "Line: " << line << std::endl; } After removing the std::ios::in everything worked as expected. All tests have been made using Boost 1.37 and MSVC8. My question is if this is the intended behaviour of mapped_file_source and if so, if that could be pointed out more prominently in the docs, since I think I've virtually read all of them and didn't find anything similiar in there. cheers, Norbert

Extracting BOOST header only libraries
by dhruva 02 Dec '08

02 Dec '08

Hi, I would like to extract the header only libraries of BOOST for internal use. Though I would like to build and install complete BOOST, I will have to integrate that into our build system. Due to lack of time, I would just like to pull subset of BOOST that does not require any build (exclude regex, system, filesyste...). It there a simple way to do it. with best regards, dhruva -- Contents reflect my personal views only!

Binding to a function with optional parameters

Is there a way to bind to a function with optional arguments? See my simple demo program below to see what I've tried: #include <boost/bind.hpp> #include <iostream> using namespace boost; using namespace std; int f(int x, int y = 0) { return x + y; } // Commented lines below don't compile. int main() { cout << bind(f, 1, 2)() << endl; // cout << bind(f, 1)() << endl; int (*p)(int, int) = f; cout << bind(p, 1, 2)() << endl; // int (*q)(int) = f; // cout << bind(q, 1)() << endl; return 0; } -- Yang Zhang http://www.mit.edu/~y_z/

[bind] an easy way to break ORD ? (where am i wrong?)
by Alexander 02 Dec '08

02 Dec '08

>From http://www.boost.org/doc/libs/1_37_0/libs/bind/bind.html#Synopsis : namespace { unspecified-placeholder-type-1 _1; unspecified-placeholder-type-2 _2; unspecified-placeholder-type-3 _3; // implementation defined number of additional placeholder definitions } Then I use placeholders like this: class X { void h(int); void f1() { return boost::bind(&X::h, this, _1)(3); } } As f1 is inline, it should be the same in all the translation units, to obey ODR. However, anonyomous namespace is different in a different translation unit, so _1 is different variable. Is One Definition Rule broken ?

-Wundef warnings
by Yang Zhang 02 Dec '08

02 Dec '08

When using the -Wundef flag with gcc, I get warnings like the following: error: "BOOST_MSVC" is not defined At least once before this was brought up on the lists: http://lists.boost.org/boost-users/2006/10/22819.php The suggested solution is to disable this warning. However, it seems to make more sense to just fix this in Boost (using #if defined(...) or #ifdef). Why not make this fix in Boost? -- Yang Zhang http://www.mit.edu/~y_z/

[program_options] is a more complicated usage supported?
by Stephan Menzel 02 Dec '08

02 Dec '08

Hi there, I'm using program_options on 1.36, quite successfully so far with only simple use cases. However, now I have to do something a little more tricky. Essentially, I'd like to parse everything before a certain point and treat everything after that as positional_options. Goal is to have a variable command line that can take arbitary commands, much in the fashion tools such as valgrind and strace would. Consider this: ./mytool --myopt 1 --anotheropt bla ./someapp --appoption 1 So mytool would need to parse it's own options 'myopt' and 'anotheropt' and then be aware of the string './someapp --appoption 1' to eventually fork whatever is there. And to make it a little more interesting some of the options should be optional. Alas, docs don't really get into that so I'm wondering if/how this could be done. This is what I got: po::options_description desc("Allowed options, after that state the desired command"); desc.add_options() ("anotheropt,a", po::value<std::string>(), "some other option") ("myopt,o", po::value<boost::uint16_t>()->default_value(1), "optional value 1") ; po::variables_map vmap; po::store(po::parse_command_line(argc, argv, desc), vmap); po::notify(vmap); // at this point I got my options. po::positional_options_description pd; pd.add("command", -1); po::parsed_options parsed = po::command_line_parser(argc, argv).options(desc).allow_unregistered().run(); std::vector<std::string> command_options = collect_unrecognized(parsed.options, po::include_positional); // here I got command_options filled with the unrecognized options. ...snip... That works OK as long as my command line does not have any options starting with - or -- at it's own. As soon as the command to be forked has such options, the first po::store() would throw because it tries to parse them. Is there any way to prevent this? Thanks and greetings... Stephan

[PROTO] Custom functions, scalar terminal and make_expr vs details::as_expr_if
by Joel Falcou 30 Nov '08

30 Nov '08

I have a large number of custom unary and bin ary function that I map using unary_expr and binary_expr. The problem is the following : my grammar has integral or floating point scalar terminal. So, when I want to create a binary function that takes any elements of my domain, I'm boudn to do the following : template<class L,class R> typename result_of::make_expr<....>::type my_custom_binary_func( L const& l, R const& r ) { return make_expr( ... ); } Alas, as I already discussed with Eric, nothign prevent me to use my_custom_binary_func over types that aren't in my grammar. To do so, I was told to use SFINAE to prune unwanted element by matching the result type of make_expr on my grammar. However, this proves cumbersome and slow down compile time by *a large factor* when I have a large number of such function (and I have like 50 or 60). So i wandered into proto source code and looked at how proto solves this problem for its binary operator. This solution seems more elegant but as it live sin proto::detail, I don't think I'm intended to use it. So, how can I have a simple and fast creation of custom expression ? Am I missing something blatant ? -- ___________________________________________ Joel Falcou - Assistant Professor PARALL Team - LRI - Universite Paris Sud XI Tel : (+33)1 69 15 66 35

Review Wizard Report for November 2008
by Ronald Garcia 30 Nov '08

30 Nov '08

============================================== Review Wizard Status Report for November 2008 ============================================== News ==== May 7 - Scope Exit Library Accepted - Awaiting SVN May 17 - Egg Library Rejected August 14 - Boost 1.36 Released New Libraries: Accumulators, Exception, Units, Unordered Containers August 27 - Finite State Machines Rejected September 10 - Data Flow Signals Rejected September 30 - Phoenix Accepted Conditionally November 3 - Boost 1.37 Released New Library: Proto November 10 - Thread-Safe Signals Accepted - Awaiting SVN November 25 - Globally Unique Identifier Library mini-Review in progress Older Issues ============ The Quantitative Units library, accepted in April 2007 is in SVN (listed as units). The Time Series Library, accepted in August 2007, has not yet been submitted to SVN. The Switch Library, accepted provisionally in January 2008, has not yet been submitted for mini-review and full acceptance. Property Map (Fast-Track) and Graph (Fast-Track) have been removed from the review queue. The author (Andrew Sutton) intends to submit a new version of this work at a later time. A few libraries have been reviewed and accepted into boost, but have not yet appeared in SVN as far as I can tell. Could some light be shed on the status of the following libraries? Apologies if I have simply overlooked any of them: * Flyweight (Joaquin Ma Lopez Munoz) * Floating Point Utilities (Johan Rade) * Factory (Tobias Schwinger) * Forward (Tobias Schwinger) * Scope Exit (Alexander Nasonov) * Time Series (Eric Niebler) * Property Tree (Marcin Kalicinski) -- No documentation in SVN Any information on the whereabouts of these libraries would be greatly appreciated. For libraries that are still waiting to get into SVN, please get them ready and into the repository. The developers did some great work making the libraries, so don't miss the chance to share that work with others. Also notice that the review process page has been updated with a section on rights and responsibilities of library submitters. General Announcements ===================== As always, we need experienced review managers. The review queue has been growing substantially but we have had 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 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! Futures ------- :Author: Braddock Gaskill :Review Manager: Tom Brinkman :Download: http://braddock.com/~braddock/future/ :Description: Joint review of the Futures libraries scheduled for 1/5/09-1/20/09. The goal of the boost.future library is to provide a definitive future implementation with the best features of the numerous implementations, proposals, and academic papers floating around, in the hopes to avoid multiple incompatible future implementations in libraries of related concepts (coroutines, active objects, asio, etc). This library hopes to explore the combined implementation of the best future concepts. Futures ------- :Author: Anthony Williams :Review Manager: Tom Brinkman :Download: http://www.justsoftwaresolutions.co.uk/files/ n2561_future.hpp (code) http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/ n2561.html (description) :Description: Joint review of the Futures libraries scheduled for 1/5/09-1/20/09. This paper proposes a kind of return buffer that takes a value (or an exception) in one (sub-)thread and provides the value in another (controlling) thread. This buffer provides essentially two interfaces: * an interface to assign a value as class promise and * an interface to wait for, query and retrieve the value (or exception) from the buffer as classes unique_future and shared_future. While a unique_future provides move semantics where the value (or exception) can be retrieved only once, the shared_future provides copy semantics where the value can be retrieved arbitrarily often. A typical procedure for working with promises and futures looks like: * control thread creates a promise, * control thread gets associated future from promise, * control thread starts sub-thread, * sub-thread calls actual function and assigns the return value to the promise, * control thread waits for future to become ready, * control thread retrieves value from future. Also proposed is a packaged_task that wraps one callable object and provides another one that can be started in its own thread and assigns the return value (or exception) to a return buffer that can be accessed through one of the future classes. With a packaged_task a typical procedure looks like: * control thread creates a packaged_task with a callable object, * control thread gets associated future from packaged_task, * control thread starts sub-thread, which invokes the packaged_task, * packaged_task calls the callable function and assigns the return value, * control thread waits for future to become ready, * control thread retrieves value from future. Notice that we are in the unusual position of having two very different libraries with the same goal in the queue at the same time. The Review Wizards would appreciate a discussion of the best way to hold these two reviews to produce the best possible addition to Boost. 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 Sandbox Vault <http://www.boost-consulting.com/ vault/index.php?action=downloadfile&filename=Pimpl.zip&directory=&>`__ http://www.ddj.com/cpp/205918714 (documentation) :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. Constrained Value ----------------- :Author: Robert Kawulak :Review Manager: Jeff Garland :Download: http://rk.go.pl/f/constrained_value.zip :Description: Review scheduled for 12/1/08-12/10/08 The Boost Constrained Value library contains class templates useful for creating constrained objects. A simple example is an object representing an hour of a day, for which only integers from the range [0, 23] are valid values: :: bounded_int<int, 0, 23>::type hour; hour = 20; // OK hour = 26; // exception! Behavior in case of assignment of an invalid value can be customized. For instance, instead of throwing an exception as in the example above, the value may be adjusted to meet the constraint: :: wrapping_int<int, 0, 255>::type buffer_index; buffer_index = 257; // OK: wraps the value to fit in the range assert( buffer_index == 1 ); The library doesn't focus only on bounded objects as in the examples above -- virtually any constraint can be imposed by using a predicate: :: // constraint (a predicate) struct is_odd { bool operator () (int i) const { return (i % 2) != 0; } }; :: // and the usage is as simple as: constrained<int, is_odd> odd_int = 1; odd_int += 2; // OK ++odd_int; // exception! The library has a policy-based design to allow for flexibility in defining constraints and behavior in case of assignment of invalid values. Policies may be configured at compile-time for maximum efficiency or may be changeable at runtime if such dynamic functionality is needed.

The task it self can be interrupted if its is cooperative (means it has some interruption points in its code -> ``this_thread::interruption_point()`` ). Polynomial ---------- :Author: Pawel Kieliszczyk :Review Manager: Needed :Download: `Boost Sandbox Vault <http://www.boostpro.com/vault/ index.php? action=downloadfile&filename=polynomial.zip&directory=>`__ :Description: The library was written to enable fast and faithful polynomial manupulation. It provides: - main arithmetic operators (+, -, * using FFT, /, %), - gcd, - different methods of evaluation (Horner Scheme, Compensated Horner Algorithm, by preconditioning), - derivatives and integrals, - interpolation, - conversions between various polynomial forms (special functions for creating Chebyshev, Hermite, Laguerre and Legendre form).

hi all, i'm trying to ignore unecognized lines of input (so following lines can be processed without the parse failing). eg: very simple scenario as follows: ///=================================================== { using namespace boost::spirit; typedef file_iterator<char> iterator_t; typedef scanner<iterator_t, scanner_policies_t> scanner_t; typedef rule<scanner_t> rule_t; int red=0, green=0, blue=0; rule_t option = (str_p("red") >> '=' >> int_p[assign(red)]) | (str_p("green") >> '=' >> int_p[assign(green)]) | (str_p("blue") >> '=' >> int_p[assign(blue)]) | ; iterator_t first(filename.c_str()); if (!first) return; iterator_t last = first.make_end(); parse(first, last, *option, space_p); } ///=================================================== wiw is a parser that will skip over the unrecognized line with input like this: ------------------ red = 255 kermit = green green = 128 blue = 128 ------------------ and correctly interpret the green and blue values.. i played around with eol_p as i want to skip whole lines of unrecognized content. i thought it would be easy, but i can't seem to get it right. can anybody do my job for me? cheers Jono

[graph] property_map from bundled properties in a subgraph, how?
by Christian Rössel 28 Nov '08

28 Nov '08

Hi, thanks for the great graph library! My first attempts with boost.graph were quite successful, but now I'm stuck. My question is: How can I get a property_map from bundled properties in a subgraph? (boost 1.34.1, g++ and VC8) In the beginning I had a bidirectional graph with bundled properties and I used a property map from the edge's bundled properties: #include <boost/graph/adjacency_list.hpp> #include <boost/graph/subgraph.hpp> using namespace boost; struct VertexProperty { // ... }; struct EdgeProperty { double length_; // ... }; typedef adjacency_list<vecS, vecS, bidirectionalS, VertexProperty, EdgeProperty> Graph; int main () { Graph g; typedef property_map<Graph, double EdgeProperty::*>::type EdgeWeightMap; EdgeWeightMap ewm = get (&EdgeProperty::length_, g); // use ewm in an algorithm ... return 0; } Everthing worked fine. Then, I had to change the graph-type from adjacency_list to subgraph ... typedef subgraph< adjacency_list<vecS, vecS, bidirectionalS, property<vertex_index_t, int, VertexProperty>, property<edge_index_t, int, EdgeProperty> > > Subgraph; int main () { Subgraph g; typedef property_map<Subgraph, double EdgeProperty::*>::type EdgeWeightMap; EdgeWeightMap ewm = get (&EdgeProperty::length_, g); // use ewm in an algorithm ... return 0; } ... and got this compile error: In instantiation of `boost::property_map<Subgraph, double EdgeProperty::*>': subgraph_property_map.cpp:45: instantiated from here ../../vendor/boost_1_34_1-multithread/boost/graph/properties.hpp:355: error: no type named `vertex_bundled' in `class Subgraph' ../../vendor/boost_1_34_1-multithread/boost/graph/properties.hpp:356: error: no type named `edge_bundled' in `class Subgraph' ../../vendor/boost_1_34_1-multithread/boost/graph/properties.hpp:360: error: no type named `vertex_bundled' in `class Subgraph' ../../vendor/boost_1_34_1-multithread/boost/graph/properties.hpp:360: error: `value' is not a member of `<declaration error>' ../../vendor/boost_1_34_1-multithread/boost/graph/properties.hpp:364: error: no type named `vertex_bundled' in `class Subgraph' ../../vendor/boost_1_34_1-multithread/boost/graph/properties.hpp:364: error: `value' is not a member of `<declaration error>' ../../vendor/boost_1_34_1-multithread/boost/graph/properties.hpp:367: error: no type named `vertex_bundled' in `class Subgraph' ../../vendor/boost_1_34_1-multithread/boost/graph/properties.hpp:367: error: `value' is not a member of `<declaration error>' ../../vendor/boost_1_34_1-multithread/boost/graph/properties.hpp:369: error: no type named `vertex_bundled' in `class Subgraph' ../../vendor/boost_1_34_1-multithread/boost/graph/properties.hpp:369: error: `value' is not a member of `<declaration error>' Is there a way to use property maps from bundled properties in a subgraph?

Problem with MSVS 2008 with gregorian
by Dan Smithers 28 Nov '08

28 Nov '08

Hi I have a problem building under studio 2008. It appears that #define max(a,b) ... collides with the member function greg_month::max() and won't compile complaining that not enough arguments are provided. I have stripped the code down test.cpp #include <windows.h> //#undef max #include "boost/date_time/gregorian/gregorian.hpp" void foo() { boost::gregorian::greg_month::max(); } If I put #undef max before including gregorian.h then it compiles. Without I get the errors warning C4003: not enough actual parameters for macro 'max' error C2589: '(' illegal token on right side of '::' error C2143: syntax error : missing ';' before '::' Has anyone seen this before? Is there a workaround? I have tried this with boost 1.37.0 and it still causes problems. thanks dan

[boost::iostreams] How to get number of bytes written?
by Milan Svoboda 28 Nov '08

28 Nov '08

Hi All, I'm using boost::iostreams and its filters to compress and decompress data. However I'm not able to retrieve number of bytes really written (number of bytes after a compression). Does anybody know how to do that? I'm currently using following code: coffset if offset to where start with writing of compressed data and after call it shall contain the length of the file. This works good to get length of the compressed block unless block of data is written somewhere in the middle of the file thus end of file is not the same as the last offset where compressed data has been written to. io::file_descriptor file(fd); file.seek(coffset, ios_base::beg); { io::filtering_ostream out; // Push the compression filter (bl->type.push(out);) out.push(file); io::write(out, buf, length); // Destroying the object 'out' causes all filters to // flush. } // Update raw length of the file. // coffset = file.seek(0, ios_base::end); Thank you for any help, Milan Svoboda

Some of the accuracy tests fail on QNX 6.4.0 x86 with GCC 4.2.4 and Dinkumware 5. Some tests such as test_carlson have a peak error 10%-40% higher than expected while for example test_ellint_1 has huge errors. I'm not sure how to proceed. I'd appreciate of someone could take a look at the trunk regression test results (runner NA-QNX640-qcc). -- Regards Niklas Angare

Trouble with asio using lib pion and boost.function
by Stephan Menzel 27 Nov '08

27 Nov '08

Hi there, I'm not actually sure this is a boost problem but I'll give it a try and ask for your opinion. Boost version is 1.36 I have a daemon here realising a web interface using pion and asio. Pion is also using asio. On Linux everything runs fine and I have my web interface, but using the same code on windows / vs 2005 I get the weirdest errors such as " Unhandled exception at 0x1004e55d in myapp.exe: 0xC0000005: Access violation reading location 0xcdcdcdd1." The debugger tells me this happens in function_template.hpp: #if !BOOST_WORKAROUND(BOOST_MSVC, < 1300) template<typename R BOOST_FUNCTION_COMMA BOOST_FUNCTION_TEMPLATE_PARMS> typename BOOST_FUNCTION_FUNCTION< R BOOST_FUNCTION_COMMA BOOST_FUNCTION_TEMPLATE_ARGS>::result_type BOOST_FUNCTION_FUNCTION<R BOOST_FUNCTION_COMMA BOOST_FUNCTION_TEMPLATE_ARGS> ::operator()(BOOST_FUNCTION_PARMS) const { if (this->empty()) boost::throw_exception(bad_function_call()); return static_cast<vtable_type*>(vtable)->invoker (this->functor BOOST_FUNCTION_COMMA BOOST_FUNCTION_ARGS); } #endif It says the static_cast rises the exception (?!) Damn MS. Anyway, I debugged into it and the last thing the debugger stepped into was in asio: size_t run(boost::system::error_code& ec) { if (::InterlockedExchangeAdd(&outstanding_work_, 0) == 0) { ec = boost::system::error_code(); return 0; } call_stack<win_iocp_io_service>::context ctx(this); size_t n = 0; while (do_one(true, ec)) if (n != (std::numeric_limits<size_t>::max)()) ++n; return n; } I don't know which line though. Can anyone help shed some light on this? Thanks and greetings... Stephan

Is there already or are there plans for components to be shared. I know this is a little outside the scope, but it does seem to be closely related. For example if I need an RGB to YUV component, it is likely that it already exists, and if not, it is likely that someone will need it after me.

How to make custom property map compatible with bgl_named_params?
by Tim Keitt 26 Nov '08

26 Nov '08

I have a custom (internal) property map defined as: struct edge_weight_extractor_map { typedef float8 value_type; typedef float8 reference; typedef WeightedEdgeTableSQLGraph::edge_descriptor key_type; typedef boost::readable_property_map_tag category; }; inline edge_weight_extractor_map::value_type get(const edge_weight_extractor_map& map, const edge_weight_extractor_map::key_type& key) { return key.edge_weight; } The map works fine as an internal property map with eg dijkstra_shortest_paths. However, I cannot get it to work when it is used in a bgl_named_params expression like: boost::brandes_betweenness_centrality(g, centrality, boost::weight_map(get(boost::edge_weight, g))); The error looks like: /usr/include/boost/property_map.hpp:25: error: no type named 'key_type' in 'struct boost::bgl_named_params<edge_weight_extractor_map, boost::edge_weight_t, boost::no_property>' /usr/include/boost/property_map.hpp:27: error: no type named 'reference' in 'struct boost::bgl_named_params<edge_weight_extractor_map, boost::edge_weight_t, boost::no_property>' /usr/include/boost/property_map.hpp:28: error: no type named 'category' in 'struct boost::bgl_named_params<edge_weight_extractor_map, boost::edge_weight_t, boost::no_property>' Do I need to specialize a traits template? Can someone post an example of how this works? (I've tried to specialize bgl_named_params itself, but unsuccessfully.) Thanks. THK -- Timothy H. Keitt http://www.keittlab.org/

Hi, I'm trying to use the Program Options library to parse command line arguments and config files. I can do this with moderate success. I am currently stuck on a solution to the problem of unrecognized options that are present in a config file. It seems that parse_config_file() does not have an obvious way to not abort reading a config file once it finds something that isn't declared in the options description. Any help on how to get around this (or just a kind of "hey you missed this bit of the manual" kind of pointer) would be very welcome. Thanks, Kevin

Maintenance Guidelines wiki page (Revison 8)
by vicente.botet 26 Nov '08

26 Nov '08

Hi, I have updated the Maintenance Guidelines wiki page. I have take in account the minor proof-reading modifications from Steve Watanave which I have overridden by error (thanks Steve!),and added a lot of thinks, maybe too much :) Please read this mail completely before jumping to the page. This page need to be completed and reworked. Please be free to add new sections to the page or improve the current ones directly or post your comments or suggestions to this list. Here it is the table of contents. [C] 1. Motivation [C] 2. Introduction [C] 1. User code breaking cases [I] 2. Versioning individual Boost libraries [O] 3. Deprecating features [I] 4. Cross version testing [C] 3. Documentation [O] 1. Tag Boost library with specific library version [developer] [O] 2. Make feature request for each feature [developer, user] [I] 3. Include the tracked tickets on the Release notes [developer] [I] 4. List the test cases associated to the trac system tickets [developer] [I] 5. List the dependency upon other Boost library [developer] [O] 6. Document behavior differences between release and debug variants [O] 7.

Developer guidelines [U] 8. User guidelines [U] 9. Release manager guidelines Tasks I plan to do: 1* Add the motivation 2* Add other examples of user code break in 2.1 3* Update the Developer, User and Release manager guidelines cross reference (7,8,9) 4* Separate on 4 pages. Main, Documentation, Coding, Test and Inspections 5* Complete incomplete guidelines [C] and improve some of them [I] Note that some guidelines applied to the developer library could be done by other people that would need SVN writtig permission. In particular the Functional Test and some documentation reports. (See below points C and E) Other points I see: A* See if the Jamfile to test the headers from Steve can be adapted to tests (Steve?) 5.1.2 Include each couple of header files in both orders B* See if the difference between source and binary compatibility is desirable (ALL) C* See if the functional test can be written by a team of interested users to don't overload the developers. These tests could in addition include multi-library tests and be stored in a directory independent from the developers one (Interested users?) D* See which configurations (deprecated or not) could be tested by the current test team. (Release Manager Team?) E* See how the following points can be automated and where this information can be included in the documentation. A separated page make possible that this task could be done by other people than the developer. (Some one knowing the Track system?) 3.3. Include the tracked tickets on the Release notes 3.4. List the test cases associated to the trac system tickets F* See how the dependencies between libraries can be automated (Release Manager Team?, CMAKE project?) 3.5. List the dependency upon other Boost library In order to know if I'm going on the right direction, I would like the interested people reply to this post stating for each section, if it is OK[O], must be completed[C]/improved [I], must be updated [U], must be removed [R] and of course any idea is welcome. You can access it directly at "https://svn.boost.org/trac/boost/wiki/Guidelines/MaintenanceGuidelines" or at "https://svn.boost.org/trac/boost/wiki" >Guidelines >Maintenance Guidelines Best regards, Vicente

Dear Friends, I am a fresh programmer and I have assigned a work where I need to handle a graph of very large size(around lakhs by lakhs matrix) with a huge amount of data. I heard that using boost library this can be done very easily, If anybody have any idea kindly guide me. Thanks in advance................ -- Thanks & Regards--- Navin Shaw

Re: [Boost-users] class API return a const&, optional, shared_ptr
by Emre Turkay 26 Nov '08

I see you have three nice options here, 1. Return a shared_ptr. 2. Return a reference and throw exception for invalid indexes. 3. Return an optional. I think all three of them are nice and safe. emre > I have a class A that holds a container of objects of type B indexed by int > for e.g. > > Typically, I have a function of A > > class A { > public: > const B& getB(int <index> ) const; > private: > std::map< int, shared_ptr<B> > listOfBs_; > }; > > The implementation of getB could be > > const B& A::getB(int <index> ) const > { > //what to do if index not found > } > > A number of solutions I think of: > > 1. > boost::optional<const B&> getB(int <index> ) const > { > } > > > 2. > change signature to > const B* getB(int <index> ) const > > > 3. > Define a > static const B notFoundB; > const B& A::getB(int <index> ) const > returns notFoundB when not found and have API users compare return value > with notFoundB > > > I suppose the cheapest in overhead/performance is 2... optional must have > some time overhead? > > Are there advised solutions?

hash_map use with serialization in Visual Studio 2005
by Mauricio Gomes 25 Nov '08

25 Nov '08

Dear all, I am learning to use the serialization library and I am having some difficulties in using hash_map. In the code below if I change to std::map it works fine. #include <cstddef> // NULL #include <iomanip> #include <iostream> #include <fstream> #include <string> #include <hash_map> #include <boost/archive/tmpdir.hpp> #include <boost/archive/text_iarchive.hpp> #include <boost/archive/text_oarchive.hpp> #include <boost/serialization/base_object.hpp> #include <boost/serialization/utility.hpp> #include <boost/serialization/list.hpp> #include <boost/serialization/hash_map.hpp> #include <boost/serialization/map.hpp> #include <boost/serialization/assume_abstract.hpp> template <typename StringType, typename SettingKeyType, typenameSettingValueType> void save_setting (StringType application_name, SettingKeyType key, SettingValueType value) { typedef stdext::hash_map<SettingKeyType, SettingValueType> Config; static stdext::hash_map<StringType, Config> app_configs; // key = application_name, value = settings map. Config cfg = app_configs[application_name]; cfg[key] = value; StringType file_name = application_name + ".cfg"; // Compose configuration file name. std::ofstream ofs (file_name.c_str ()); boost::archive::text_oarchive oa (ofs); oa << cfg; } int main(int argc, char *argv[]) { save_setting<std::string, int, std::string> ("test_app", 1, "value1"); } However if I try to use stdext::hash_map then it fails to compile with the following error: 1>c:\boost_1_37_0\boost\serialization\access.hpp(109) : error C2039: 'serialize' : is not a member of 'stdext::hash_map<_Kty,_Ty>' 1> with 1> [ 1> _Kty=int, 1> _Ty=std::string 1> ] It is most likely related to the fact that hash_map is not in the std namespace. I have searched the boost-users list and I have found this: http://lists.boost.org/boost-users/2005/08/13183.php but it refers to a GNU/Linux environment. Has this been addressed in 1.37 (that's the version I am using) ? Any suggestions ? Thank you in advance for your help. -- Mauricio Gomes

[dataflow][iostreams]Can someone Compare/Contrast
by Duane McKinney 25 Nov '08

25 Nov '08

If it has already been done I appologize. They seem very similar to me. Is it just a matter of style? It seems like dataflow lends itself better to dealing with blocks/frames of data than the iostreams library. I would appreciate any clarification though.

Exception when constructing empty list in shared memory (boost::interprocess::list)
by Roland 25 Nov '08

25 Nov '08

Hello all (Hi Ion) Here's a small piece of code that causes an exception to be thrown (when it shouldn't). The environment is MSVC8 (VS2005SP1) with Boost 1.37. The code is an adaption of one of the samples in the interprocess documentation. The samples creates a vector of ClassWithList in shared memory. Then it creates an instance of ClassWithList and push_back()'s it onto the vector. >From what I can gather, the List member (which is a list<>) is constructed in shared memory, and deep within, it calls class segment_manager_base<MemoryAlgorithm>::allocate_many(size, 0). The MemoryAlgorithm is rb_tree_best_fit<..>. allocate_many (imo correctly) returns NULL for a 0-element allocation, which causes the exception to be thrown. Replacing the member variable type "list<>" with a "vector<>" makes everything work nicely. (allocate_many() is not used in that case). Thanks roland PS: Other than this, interprocess::* has been great! #include <boost/interprocess/managed_shared_memory.hpp> #include <boost/interprocess/containers/vector.hpp> #include <boost/interprocess/containers/list.hpp> #include <boost/interprocess/allocators/allocator.hpp> int main () { using namespace boost::interprocess; //Typedefs typedef managed_shared_memory::segment_manager SegmentManager; typedef struct ListElem { int nValue; } ListElem; typedef allocator<ListElem, SegmentManager> ListElemAllocator; typedef list<ListElem, ListElemAllocator> ListElemList; typedef allocator<void, SegmentManager> VoidAllocator; class ClassWithList { public: ClassWithList(const VoidAllocator &alloc) : List(alloc) {} ListElemList List; }; typedef allocator<ClassWithList, SegmentManager> ClassWithListAllocator; typedef vector<ClassWithList, ClassWithListAllocator> ClassWithListVector; shared_memory_object::remove("myshm"); try{ managed_shared_memory shm(create_only, "myshm", 10000); //Create allocators VoidAllocator voidallocator(shm.get_segment_manager()); ClassWithListAllocator classwithlistallocator(shm.get_segment_manager()); //Create a vector of strings in shared memory.

[lambda] Subscripting in lamda expressions.
by Robert Jones 25 Nov '08

25 Nov '08

Here's a little quick and dirty square matirx multiply I've written. Ok. I know this leaves a lot to be desired on the quality front, but I'm not in a position to rewrite the whole system here! The lambda function argument to accumulate is clearly not right, but how I write something that implements the intention here? Thanks, Rob. typedef int block[ BLOCK_SIZE ][ BLOCK_SIZE ]; void matrix_product( block & result, const block & l, const block & r ) { typedef boost :: counting_iterator< unsigned > Iter; using namespace boost :: lambda; for ( unsigned y = 0; y != BLOCK_SIZE; ++ y ) for ( unsigned x = 0; x != BLOCK_SIZE; ++ x ) result[ y ][ x ] = std :: accumulate( Iter( 0 ), Iter( BLOCK_SIZE ), 0, l[ y ][ _1 ] * r[ _1 ][ x ] ); }

class API return a const&, optional, shared_ptr
by Hicham Mouline 25 Nov '08

25 Nov '08

hello, I have a class A that holds a container of objects of type B indexed by int for e.g. Typically, I have a function of A class A { public: const B& getB(int <index> ) const; private: std::map< int, shared_ptr<B> > listOfBs_; }; The implementation of getB could be const B& A::getB(int <index> ) const { //what to do if index not found } A number of solutions I think of: 1. boost::optional<const B&> getB(int <index> ) const { } 2. change signature to const B* getB(int <index> ) const 3. Define a static const B notFoundB; const B& A::getB(int <index> ) const returns notFoundB when not found and have API users compare return value with notFoundB I suppose the cheapest in overhead/performance is 2... optional must have some time overhead? Are there advised solutions? Favourites in terms of style? Regards,

[SSL - Memory Leak] Adding include <boost/asio/ssl.hpp>
by Ariel Somaschini 25 Nov '08

25 Nov '08

In a simple example of Hello World, created with Microsoft VC 2008 Express Edition on Windows and Linux with KDevelop, to add include <boost/asio/ssl.hpp> produces a Memory Leak. In the case of Windows, using DevPartner, it detects the file openssl_init.hpp on line 84. In the case of Linux, still report valgrind reachable 48 bytes in 3 blocks. The example is very simple: #ifdef HAVE_CONFIG_H #include <config.h> #endif #include <iostream> #include <cstdlib> #include <boost/asio/ssl.hpp> // Memory Leak using namespace std; int main(int argc, char *argv[]) { cout << "Hello, world !" << endl; return EXIT_SUCCESS; } Can somebody help me? Thx Ariel _________________________________________________________________

I am trying to use a boost library version 1.37.0 (date time specifically) with visual C++ 6.0 , the "Getting started" instructions indicate the libraries need to be recompiled, so far I have not been successful and would like to know if it is possible to use this version with Visaul Studio 6.00.
