[interprocess] Determine size of managed_shared_memory
by Kai Benndorf 12 Oct '19

12 Oct '19

Hi all, I want to create a managed_shared_memory in exactly the size I needed. Therefore I do something like this: size = sizeof( common_managed_shared_memory ); size += sizeof( MyClassInSharedMem ); managed_shared_memory segment(create_only, "name", size ); MyClassInSharedMem allocates itself some memory by segment->allocate(). I added this also to the size, but get a boost::interprocess::bad_alloc exception on allocating this additional memory. Are there some magic bytes I forgot to add? Many thanks in advance Kai

[statechart] Passing parameters from event to State Local Storage
by Christophe Bourez 16 Nov '16

16 Nov '16

I need to maintain a parameter into the state local storage. This parameter is initially contained in the event that causes the transition to the target state. I give hereafter a small illustrative example. typename sc = boost::statechart; class EvTest : public sc::event<EvTest> { public: EvTest(std::size_t val) : value(val) {} std::size_t getValue() const { return this->value; } private: std::size_t value; }; class MyStateMachine; class StSource; class StTarget; class StSource : public sc::simple_state<StSource, MyStateMachine> { public: typedef sc::custom_reaction<EvTest> reactions; sc::result react(const EvTest &event) { // How to pass event.getValue() to the target state ? transit<StTarget>(); } }; class StTarget : public sc::simple_state<StTarget, MyStateMachine> { public: StTarget(std::size_t val) : val(value) {} private: std::size_t value; }; Thanks, Christophe

Hi, I'm looking for a solution to serialize boost::statechart objects. I'm aware that this feature is on the statechart library todo list but was wondering if there are any workaround to achieve this with the latest boost release (1.34) ? thanks for your help ! mbrodeur65 -- View this message in context: http://www.nabble.com/Statechart-serialization-tf4131326.html#a11749139 Sent from the Boost - Users mailing list archive at Nabble.com.

[Thread] Read-write locks
by lfrfly＠icqmail.com 18 Sep '14

18 Sep '14

I'm trying to create a standard read/write lock using Boost Threads, and I'm having a bit of difficulty mapping the Boost concepts onto the usual ones. A read/write lock should have several states: Locked for reading (multiple threads may lock at once), locked for writing (only one thread may lock, and no threads may be locked for reading at the same time), and unlocked. Ideally it would be nice if an RWL which is locked for reading may temporarily upgrade to locked for writing, then return to the locked for reading state. Boost supports several relevant notions of locking: shared locking, upgrade locking, and exclusive locking. This to me is a confusing distinction. In particular, a shared_mutex seems appropriate as the basis for a RWL, but is lock_upgrade() the equivalent of a write lock and lock_shared the equivalent of a read lock? This is unclear. If "upgrade locking" is not the same as "exclusive locking", then is an upgrade lock actually exclusive? Could someone please clarify this.

[Statechart] How to decide between post_event and process_event atrun time ?
by Philippe DAVID 22 Jul '14

22 Jul '14

Hi, I have a method in which I want to post/process an event. The thing is, this method can be called from outside the state machine (so I need to call process_event), or indirectly by a reaction of the state machine (in this case I must call post_event since process_event is not reentrant). I don't want to write 2 distinct methods to do this (one that calls post, and the other process), I would much rather prefer adding a 'if' in my method that tells me if I have to call process_event or post_event (if I'm being called indirectly by the state machine or not). Is there a way to do this with statechart ? regards, Philippe

Problems calling make_reversed_graph in a call to dijkstra from version 1.48
by Berit Dangaard Brouer 08 Apr '14

Hi, First of all thank you for providign the boost BGL library. I use it extensively. I am having some problems with some code, that works just fine using boost version 1.46, but cannot compile using version 1.48 and higher. I have a Bidirectional Graph using bundled properties defined as: struct Port { Port(int index=-1, int type=-1, int port_code=0, string UN="NN", string name="NN", int service_id=-1 ): m_index(index), m_type(type), m_port_code( port_code), UNLOCODE(UN), m_name(name), m_service_id(service_id) {} int m_index; int m_type;//0 port, 1 port call int m_port_code; string UNLOCODE; string m_name; int m_service_id; }; struct Edge { Edge( int id=-1, int type=-1, double weight=0.0, double cost=0.0, double dual_cost=0.0, double util=0.0, double cap=0.0, double r_cap=0.0 ) : m_idx(id), m_type(type), m_weight(weight) , m_cost(cost), m_dual_cost(dual_cost), m_utilization(util), m_capacity(cap), m_res_cap(r_cap) {} unsigned int m_idx; int m_type;//0 is load edge, 1 is voyage edge, 2 forfeited edge (commodity link) double m_weight; //distance double m_cost; //cost - only on load/unload/transhipment edges double m_dual_cost; double m_utilization; double m_capacity; double m_res_cap; //residual capacity }; //Graph typedef adjacency_list< vecS , vecS , bidirectionalS, Port, Edge> mcf_graph; I am trying to make a call to dijkstra on a reversed graph as follows: (the reversed graph is also a filtered graph, but I do not think this is an issue: dijkstra_shortest_paths (make_reverse_graph(fg), before_p, predecessor_map ( &p[0] ).distance_map ( &d[0] ).weight_map ( get ( &Edge::m_weight, fg) ).vertex_index_map ( get ( vertex_index,fg ) ) ); which works fine in 1.46, but it seems in 1.48 I can no longer use make_reverse_graph(<mcf_graph&>) (returning a reverse graph) with the bundled properties from fg. and I get the error (compressed summary - full details attached) usr/include/boost/property_map/property_map.hpp:354:56: error: no match for 'operator[]' in '((const boost::bundle_property_map<boost::adjacency_list<boost::vecS, boost::vecS, boost::bidirectionalS, Port, Edge>, boost::detail::edge_desc_impl<boost::bidirectional_tag, long unsigned int>, Edge, double>&)pa)[k]' /usr/include/boost/property_map/property_map.hpp:354:56: note: candidate is: In file included from /usr/include/boost/graph/adjacency_list.hpp:44:0, from /home/chrkr/git/lsndp/include/ipheuristic.h:36, from /home/chrkr/git/lsndp/src/ipheuristic.cpp:29: /usr/include/boost/graph/properties.hpp:399:15: note: T& boost::bundle_property_map<Graph, Descriptor, Bundle, T>::operator[](boost::bundle_property_map<Graph, Descriptor, Bundle, T>::key_type) const [with Graph = boost::adjacency_list<boost::vecS, boost::vecS, boost::bidirectionalS, Port, Edge>; Descriptor = boost::detail::edge_desc_impl<boost::bidirectional_tag, long unsigned int>; Bundle = Edge; T = double; boost::bundle_property_map<Graph, Descriptor, Bundle, T>::reference = double&; boost::bundle_property_map<Graph, Descriptor, Bundle, T>::key_type = boost::detail::edge_desc_impl<boost::bidirectional_tag, long unsigned int>] /usr/include/boost/graph/properties.hpp:399:15: note: no known conversion for argument 1 from 'const boost::detail::reverse_graph_edge_descriptor<boost::detail::edge_desc_impl<boost::bidirectional_tag, long unsigned int> >' to 'boost::bundle_property_map<boost::adjacency_list<boost::vecS, boost::vecS, boost::bidirectionalS, Port, Edge>, boost::detail::edge_desc_impl<boost::bidirectional_tag, long unsigned int>, Edge, double>::key_type {aka boost::detail::edge_desc_impl<boost::bidirectional_tag, long unsigned int>}' From various sources I understand that as of 1.48 reverse graph is no longer an image of the graph, but another object, where I need the actual property maps and the property maps of the reversed graph, but I did not get much wiser on how to call dijkstra with the reversed graph given these new description.

[asio] resolver::cancel() problem
by Matthew Edwards 14 Mar '14

14 Mar '14

In my application (and a separate test program) it seems as though the cancel() function on the resolver does not work as intended. For async resolves, the cancel functionality should abort them immediately and pass an 'operation aborted' error code to the callback handler. In my tests, I will resolve an invalid domain (this causes the resolve to take a few seconds, to demonstrate the problem), sleep for 100ms, then call cancel on the resolver object. No cancelling actually occurs, and the callback is simply triggered after a few seconds with a "No host found" error code, not the expected operation aborted. Has anyone experienced this before, or know how I might be using the resolver incorrectly?

Boost.Mock ?
by Mathieu Champlon 20 Jan '14

20 Jan '14

Hello, I initially sent the following message to the boost-dev mailing list, but I'm thinking this might reach more potential users here on boost-users. Would a library for mock objects be of interest ? The documentation can be found here : http://mat007.users.sourceforge.net/boost_mock/ An archive is also available for download there : http://sourceforge.net/projects/mat007.u/files/boost-mock.zip It's been converted from turtle (http://turtle.sourceforge.net/) which was mentioned on the mailing-lists a couple of times in the past. There is a catch in that it needs Boost.Test from the release branch and doesn't compile with the trunk. The changes are minimal though and I can provide a patch if anyone is interested. Is anyone already using the library who would like to see it in Boost ? Or is anyone using another mock object library who wants to give it a go ? Or even better has anyone tried it and decided to user another library who would like to comment on it ? I would be highly interested in any feedback ! Thank you, MAT.

[Test] Where to learn about boost::itest::mock_object?
by Mateusz Loskot 20 Jan '14

20 Jan '14

Hi, I'm looking for a simple mocking library to use together with Boost.Test. There is Turtle (aka Boost.Mock) and googlemock. During retrospection of the big thread on Boost.Test future [1], I found this curious post by Gennadiy [2] about mock_object. I had no idea such facility lives in Boost.Test and it looks it's been there for very long time. I can't find any documentation about mock_oboject, only a couple of examples. So, I have a few questions: Is the mock_object an internal feature or is it dedicated (and ready) to use by Boost.Test users? What are basic features of this mocking facility? How does it compare to Turtle or googlemock? [1] http://thread.gmane.org/gmane.comp.lib.boost.devel/234297 [2] http://thread.gmane.org/gmane.comp.lib.boost.devel/234297/focus=234621 [3] find /home/mloskot/dev/boost/_svn/trunk/libs/test -type f | xargs grep mock_object Best regards, -- Mateusz Loskot, http://mateusz.loskot.net

[boost.test] How to register custom exception for auto test?
by Jörg Becker 13 Jan '14

13 Jan '14

Hi, I'm using the test library of boost 1.49.0 for my unit tests. It works fine so fare, but if my program throws an error, I get the default error message unknown location(0): fatal error in "excption1_test": unknown type, witch hides the original error message. I tried to register an error translator, but without success. Here is what I tried (modified test/test/custom_exception_test.cpp to use auto test with global fixture): #define BOOST_TEST_MODULE "boost test custom_exception_test" #include <boost/test/unit_test.hpp> #include <boost/test/unit_test_monitor.hpp> using namespace boost::unit_test; BOOST_AUTO_TEST_SUITE( custom_exception_testsuite ) struct my_exception1 { explicit my_exception1( int res_code ) : m_res_code( res_code ) {} int m_res_code; }; void throw_my_exception1() { throw my_exception1( 12 ); } void my_exception1_translator( my_exception1 ) { BOOST_TEST_MESSAGE( "Caught my_exception1" ); } class my_config { public: my_config () { unit_test_monitor.register_exception_translator<my_exception1>( &my_exception1_translator ); } }; BOOST_GLOBAL_FIXTURE( my_config ) BOOST_AUTO_TEST_CASE( excption1_test ) { throw_my_exception1(); } BOOST_AUTO_TEST_SUITE_END() Can anybody tell me what I'm missing?

[BOOST]BOOST_AUTO_TEST_CASE_TEMPLATE vs BOOST_AUTO_TEST_CASE

Hi, Scenario1: Both files are present in the same Project BoostUnitTest. fileA: typedef boost::mpl::list<long long,unsigned char> test_types; BOOST_AUTO_TEST_SUITE(MySuite) BOOST_AUTO_TEST_CASE_TEMPLATE( my_test, T, test_types ) { BOOST_CHECK_EQUAL( sizeof(T), (unsigned)4 ); } BOOST_AUTO_TEST_SUITE_END() fileB: typedef boost::mpl::list<long long,unsigned char> test_types; BOOST_AUTO_TEST_SUITE(MySuite) BOOST_AUTO_TEST_CASE_TEMPLATE( my_test, T, test_types ) { BOOST_CHECK_EQUAL( sizeof(T), (unsigned)4 ); } BOOST_AUTO_TEST_SUITE_END() As shown above, MySuite is extended across 2 files fileA and fileB. The BOOST_AUTO_TEST_CASE_TEMPLATE name is same across the both the files and and the suite name is also same across both the files.. Boost is able to differentiate between the 2 test cases and the test cases are executed. Scenario2: fileA: BOOST_AUTO_TEST_SUITE(MySuite) BOOST_AUTO_TEST_CASE( my_test) { BOOST_CHECK_EQUAL(1,1); } BOOST_AUTO_TEST_SUITE_END() fileB: BOOST_AUTO_TEST_SUITE(MySuite) BOOST_AUTO_TEST_CASE_TEMPLATE( my_test ) { BOOST_CHECK_EQUAL( 1,1 ); } BOOST_AUTO_TEST_SUITE_END() In the scenario2, I get a compile time error (Error 1 error LNK2005: "public: void __thiscall mySuite::insuite2::test_method(void)" (?test_method@insuite2@mySuite@@QAEXXZ) already defined in BoostUnitTest.obj) which basically suggests that one or more multiply defined symbols are found. Why is the behaviour different in these 2 scenarios? How is Boost able to differenciate between the 2 test cases in Scenario1? Mit freundlichen Grüßen / Best Regards, Hemanth Choudary MV RBEI/ETA1

Threading question

I have the following code and it terminates as expected. When I call the destructor it interrupts the thread. But if I change the this_thread::sleep to this_thread::yield the join() never happens and the program hangs. I must be misunderstanding yield. But I really don't want a sleep if possible. Thanks, John MessageQueueHandler::~MessageQueueHandler() { // Terminate the thread pMessageQueueInputThread->interrupt(); pMessageQueueInputThread->join(); delete pMessageQueueInputThread; } void MessageQueueHandler::MessageQueueInputThread() { unsigned int receivedSize; unsigned int priority; char buffer[queueMaximumMessageSize]; boost::this_thread::interruption_enabled(); try { while(1) { // Process all messages in the queue while(inputMessageQueue->try_receive(buffer, queueMaximumMessageSize, receivedSize, priority)) { BaseMessage * msg = reinterpret_cast<BaseMessage*>(buffer); callbackTable->DispatchMessage(msg); boost::this_thread::interruption_point(); } // Give other threads a chance to run // This is also an interruption point boost::this_thread::sleep(boost::posix_time::millisec(50)); <==Here } } catch(boost::thread_interrupted const&) { return; } } ___________________________________ John Davies Contractor Home Respiratory Care Philips Home Healthcare Solutions 1740 Golden Mile Highway Monroeville, PA 15146 Email: john.davies(a)philips.com Fax: 724-387-4109 ________________________________ The information contained in this message may be confidential and legally protected under applicable law.

Fwd: support for bjam projects in IDE
by Witold E Wolski 06 Dec '13

06 Dec '13

Hi, I will have to work on bjam based project (rather big). I normally use QT Creator for programming and work with cmake based project. I could't find any hint how to set up an bjam project to work with QT neither information about any IDE which supports bjam. Do boost developer use vim and debug using gdb only? Actually the other guys on the project wrote some python scripts which parse bjam output to generated vcproj files :-@ I would be happy to hear from someone who are happy using bjam with qtcreator or any other IDE for larger projects and how to set this up. All my searches so far regarding bjam return almost exclusively FUD (http://en.wikipedia.org/wiki/Fear,_uncertainty_and_doubt) but looking at the Jamroot.jam file of the project (more than 1000 lines) I am inclinded to believe it. ;-( -- Witold Eryk Wolski -- Witold Eryk Wolski

Boost.Log: Set formatter for named_scope attr.
by David Puffer 14 Nov '13

14 Nov '13

Hi, Being new to Boost.Log (and Boost in general) I have spent the last few days trying to implement Boost.Log - which Is working fairly well by now. However - I encountered one problem that I've not been able to solve by now, although it seems to me quite trivial: I have successfully registered the "named_scope" attribute and I am populating its value by a call to BOOST_LOG_FUNCTION. This works well and I can see the function-name in my log-output. However - I also want the line-number and the file-name, and discovered that there's a possibility to set the output-format of the "named_scope" attribute (which already incorporates file-name and line-number info) like so: #include <boost/log/expressions/formatters/named_scope.hpp> sink->set_formatter(expr::stream << expr::format_named_scope("Scopes", "%n")); As documented here: http://www.boost.org/doc/libs/1_54_0/libs/log/doc/html/log/detailed/express… I just don't seem to find any way to get to my sink - which is configured in a settings-file and evaluated by a call to the init_from_stream() function. Is there any way to query for all the sinks - or get a sink by name? How is one supposed to set a sink formatter for a sink which was generated by the library and not the user? Or is there a way to specify the output-format for named attributes via a settings-file as well? As far as I can see it's only possible to format the output of a log record as a whole - but not single attributes. Also: Is it correct, that the above function will only set the format for the "Scopes" attribute - which means I could call this function repeatedly for lets say the "TimeStamp" attribute as well? Best regards, David

Boost range iterator pointing to wrong element
by Giorgos Sermaidis 09 Oct '13

09 Oct '13

Hi all, I have a vector<pair<bool, int>> from which I need to read (and possibly write) only the vector elements for which the boolean value of the pair is true. I am using boost range filter and reverse adaptors to do that. However, I noticed that the order of the adaptors, ie whether I use reversed | filtered or filtered | reversed produces different results. In fact, for the latter when I use an iterator to the transformed range to change the boolean value of the pair, then the iterator after the change points to a different vector element. This does not happen when I use reversed | filtered. Below is the code demonstrating the issue. Any ideas as to why this is happening are much appreciated! #include <boost/range/adaptors.hpp> #include <vector> #include <utility> #include <iostream> using namespace boost::adaptors; using container_type = std::vector<std::pair<bool,int>>; struct to_include { bool operator()(const std::pair<bool,int>& x) { return x.first; } }; int main() { container_type container; /* element0: 1, 1 */ /* element1: 1, 2 */ /* element2: 1, 3 */ for(size_t i=0; i!=3; ++i) container.push_back(std::make_pair(true, i+1)); container_type container_cpy = container; /* filter and then reverse */ auto fr = container | filtered(to_include()) | reversed; auto fr_it1 = fr.begin(); auto fr_it2 = std::next(fr_it1); fr_it2->first = false; std::cout << "FILTER AND THEN REVERSE\n"; std::cout << fr_it2->first << " " << fr_it2->second << '\n'; /* prints (1,1) instead of (0,2) */ /* reverse and then filter */ auto rf = container_cpy | reversed | filtered(to_include()); auto rf_it1 = rf.begin(); auto rf_it2 = std::next(rf_it1); rf_it2->first = false; std::cout << "\nREVERSE AND THEN FILTER\n"; std::cout << rf_it2->first << " " << rf_it2->second << '\n'; /* prints (0,2) */ return 0; }

[parameter] named template parameters
by ilya shlyakhter 03 Oct '13

03 Oct '13

Some questions about the Boost.Parameter library: - seems like it hasn't been updated in some time -- is it still supported? - when specifying type constraints for named template parameters, is it possible to specify constraints among several type parameters (the way graph_type is used in section 2.1.5.6.1 of the documentation) - are there any issues in the interaction of Boost.Parameter and template specialization, i.e. how do I specialize the template on the values of some of the named parameters? Thanks, ilya

Valgrind errors with ASIO
by Bo Jensen 03 Oct '13

03 Oct '13

Hi, I have build a job queue with a combination io_service, io_service::work, packaged_task and a thread group. I am seeing randomly either segfaults or strange asserts in pthread or even malloc, which suggest to me memory is being corrupted somehow. The problem is it does not show in debug mode running under valgrind, but if I run valgrind on the non debug version I get valgrind errors in pthreads called from asio. I try to downgrade my boost lib from 1.54 to 1.52, but still the same. I am completely stuck on this, does anyone have some hints to possible causes ? I can not show the complete source since it's not possible to isolate, but here's the types I have : std::vector<boost::shared_ptr<ExceptionTransfer> > io_error_; std::vector<boost::shared_future<BasisSelectRet> > io_future_; boost::asio::io_service io_service_threads_; boost::shared_ptr<boost::asio::io_service::work> io_work_; boost::thread_group io_threads_; I am calling it ala like this : /* Create new tasks */ basistasks_[workerid] = boost::make_shared<boost::packaged_task<BasisSelectRet> >(boost::bind(&CallBasisSelection,&worker,boost::ref(io_error_[workerid]))); /* Make threads */ io_service_threads_.post(boost::bind(&boost::packaged_task<BasisSelectRet>::operator(),basistasks_[workerid])); io_future_[workerid] = basistasks_[workerid]->get_future().share(); The called function is defined as follows (BasisSelectRet is just a enum) : /* Helper function */ BasisSelectRet CallBasisSelection(TreeWorker *worker, boost::shared_ptr<ExceptionTransfer> &error) { BasisSelectRet ret = BasisSelectRetOk; try { worker->BasisSelection(); } catch( ... ) { error->SetException(boost::current_exception()); } return ret; } I can wait for a job to finish like this : boost::wait_for_any(io_future_.begin(),io_future_.end()); Here's the val grind errors : ==3723== by 0xB5D77BF: ??? ==3723== ==3723== Thread 5: ==3723== Invalid read of size 4 ==3723== at 0x6506C01:

BGL: write_graphviz_dp taking in count values of dynamic_properties
by Pablo Madoery 30 Sep '13

Hi, I have the following code that print a graph taking in count values of dynamic_properties: #include<iostream> #include <boost/graph/adjacency_list.hpp> #include <boost/graph/graphviz.hpp> using namespace std; using namespace boost; struct VertexInfo { int id; }; struct EdgeInfo { double weight; bool enable; }; typedef adjacency_list<listS, vecS, bidirectionalS, VertexInfo, EdgeInfo> Graph; int main() { //////////////////////////////////////////////////////////////////////////////////////////// Graph graph; Graph::vertex_descriptor a = add_vertex(graph); Graph::vertex_descriptor b = add_vertex(graph); Graph::vertex_descriptor c = add_vertex(graph); Graph::vertex_descriptor d = add_vertex(graph); Graph::edge_descriptor e1 = (add_edge(a, b, graph)).first; Graph::edge_descriptor e2 = (add_edge(a, b, graph)).first; Graph::edge_descriptor e3 = (add_edge(b, c, graph)).first; Graph::edge_descriptor e4 = (add_edge(c, a, graph)).first; Graph::edge_descriptor e5 = (add_edge(c, a, graph)).first; Graph::edge_descriptor e6 = (add_edge(c, d, graph)).first; graph[e1].weight = 5; graph[e2].weight = 10; graph[e3].weight = 6; graph[e4].weight = 14; graph[e5].weight = 2; graph[e6].weight = 3; graph[e1].enable = true; graph[e2].enable = false; graph[e3].enable = true; graph[e4].enable = false; graph[e5].enable = true; graph[e6].enable = false; ofstream ofs("graph.dot"); dynamic_properties dp; dp.property("node_id", get(vertex_index, graph)); dp.property("label", get(&EdgeInfo::weight, graph)); dp.property("taillabel", get(&EdgeInfo::enable, graph)); write_graphviz_dp(ofs, graph, dp); cout << "fin" << endl; return 0; } /////////////////////////////////////////////////////////////////////////////////// there is a property called "enable" in the edges that I print in the tails of the arrows. But what i really want is that when enable = false the style of the arrow be different ("invis" for example). How can i do that? Thanks!
