The culturally correct formating in (most of) India would be something like "12,34,56,789" grouping() returns a vector with .size()=2, [0]='\3', and [1]='\2'.

Kempf (bill_kempf) Summary: thread identification and getting the id Initial Comment: There are no identification for created threads in thread_group (at least working correctly under Linux). If it will be possible to set an id in function "create_thread" and have a function to get the id of current thread, then it will be a way to connect certain thread with some other resources (to do monitoring for example and for other purposes) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=357586&aid=1480523&group_… ------------------------------------------------------- Using Tomcat but need to do more?

Re: [boost] Including thread.hpp causes coredump on AIX

How about these linker errors on AIX? Do others see these with Boost on AIX? (As previously noted, the code I'm linking in this example doesn't even make Boost calls...) chris.grayson(a)database-brothers.com wrote: > I do get these linker errors: > ld: 0711-224 WARNING: Duplicate symbol: ._GLOBAL__I_thread_creds_t > ld: 0711-224 WARNING: Duplicate symbol: ._GLOBAL__D_thread_creds_t > ld: 0711-224 WARNING: Duplicate symbol: _GLOBAL__F_thread_creds_t > ld: 0711-224 WARNING: Duplicate symbol: thread_creds_t > ld: 0711-224 WARNING: Duplicate symbol: _GLOBAL__I_thread_creds_t > ld: 0711-224 WARNING: Duplicate symbol: _GLOBAL__D_thread_creds_t > ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more > information.

Re: [boost] Including thread.hpp causes coredump on AIX

I don't know why my posts aren't coming through - here's my third try at sending my original message, with the three source files (again). I'm trying to use the Boost threads library in an application on AIX 5.3, but I'm having serious trouble. I've narrowed it down to the test code below. When both "main.cpp" and "Class1.cpp" include <boost/thread/thread.hpp>, the compiled application coredumps whenever an exception is thrown in Class1. When the thread.hpp include statement is commented out - in either file - the exception is thrown and caught fine, with no coredump. Note that neither main.cpp nor Class1.cpp *uses* any Boost threads code. This problem occurs with both gcc 3.3.2 (as provided by IBM in their "AIX Toolbox") and gcc 3.4.6 (as built from source). In both cases, the AIX linker "ld" is used, per both IBM and GNU's recommendations. This seems to only happen on AIX 5.3. The same code on Linux, Solaris and AIX 5.1, compiled the same way, does not crash in this way. This also occurs with both Boost 1.33.0 and 1.33.1. I'm currently compiling against the latest Boost source (1.33.1), though it's not built, since I'm only including headers, and not linking anything. ---- main.cpp ---- #include <iostream> #include "Class1.h" #include <boost/thread/thread.hpp> main () { std::cout << "starting main()" << std::endl; Class1 c; c.noop(); std::cout << "exiting main() normally" << std::endl; } ---- Class1.h ---- class Class1 { public: void noop(); }; ---- Class1.cpp ---- #include <iostream> #include "Class1.h" #include <boost/thread/thread.hpp> void Class1::noop () { std::cout << "entering Class1::noop()" << std::endl; try { std::cout << "..throwing exception" << std::endl; throw (2.1); } catch (...) { std::cout << "..caught exception in Class1.noop()" << std::endl; } std::cout << "..leaving Class1.noop()" << std::endl; return; } The previous files are built and run with these commands: > g++ -o crasher -I$HOME/boost/boost_1_33_1 main.cpp Class1.cpp > ./crasher I do get these linker errors: ld: 0711-224 WARNING: Duplicate symbol: ._GLOBAL__I_thread_creds_t ld: 0711-224 WARNING: Duplicate symbol: ._GLOBAL__D_thread_creds_t ld: 0711-224 WARNING: Duplicate symbol: _GLOBAL__F_thread_creds_t ld: 0711-224 WARNING: Duplicate symbol: thread_creds_t ld: 0711-224 WARNING: Duplicate symbol: _GLOBAL__I_thread_creds_t ld: 0711-224 WARNING: Duplicate symbol: _GLOBAL__D_thread_creds_t ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.

[fusion] How does is_pointer< Sequence > work?
by Andreas Huber 02 May '06

02 May '06

Hi Joel & Dan Going through the fusion quick start, I'm wondering how the expression ... for_each(filter_if<boost::is_pointer<Sequence> >(seq), print_xml()); ... could ever work? Shouldn't that rather read similar to ... for_each(filter_if<boost::is_pointer<_> >(seq), print_xml()); ... so that the _ placeholder can be replaced with the individual types in the sequence? Thanks, -- Andreas Huber When replying by private email, please remove the words spam and trap from the address shown in the header.

[SoC][Act]Concurrency library
by Matt Calabrese 01 May '06

01 May '06

For the past month or so I've been working on a concurrency library which brings active types, atomic types, and parallel loop constructs and algorithms to C++. I am familiar with some of the concurrency projects already underway, though I'm sure my library would be able to coexist. I plan on proposing through SoC sometime later this week. Over the past two days I've also begun writing up some documentation using QuickBook to give a general idea as to the design of the library. Though I do have a lot of features already implemented, there is still a very large amount of work to be done prior to completion. Some feedback before I make the formal proposal would be nice, and it'd also be great to see if anyone is interested. Keep in mind that the documentation is only a rough outing and so there are a few unconnected links, but I do include a brief introduction and some basic usage examples including code snippets. The library is reference to as Surge.Act as that is the namespace I use for my personal libraries, though it will of course be changed to Boost.Act if it were to be accepted. http://members.gamedev.net/Rivorus/surge/html/index.html For those familiar with the concept of futures and are confused as to why they are not mentioned, I will be adding all of that information to the rationale over the upcoming few days. I also apologize for not having better code examples. -- -Matt Calabrese

I read those and was sympathetic to the terminology arguments you made. L?pez Mu?oz believes it is too late to make those sort of changes. I disagree with him on that, but it isn't clear enough yet to me what would be better terminology. I didn't follow the other matter you raised in those posts. Please correct me if I'm wrong, but it seems B.MI's serialization forces you to receive a B.MI instance with the same number of indices as was sent. While on one level it is impressive that B.MI preserves the relative order of equal elements, it has a cost. If you have a B.MI with 3 indices in a server and only need one or two indices in a client, you have some work to do. In order to accomplish this I think you would have to receive a B.MI with the same indices as was sent and then write code that copies the contents of that B.MI to either a simpler B.MI or an STL container. Does the preservation of the relative order of elements matter more than this sort of flexibility? Brian www.webEbenezer.net
