Robert – Thanks for your comments! 1) It was a typo – I got input archives and output archives backwards when describing the problem in my original email. I was actually using the as you describe. 2) There were several inline constructors in some derived classes not used by serialization. I removed them. 3) The archives were being closed but not the streams. Now both output archive and output stream are closed before the input stream and archive are created. 4) I also set up all the serialization code using NVPs so I could debug using XML archives based on a comment I saw in another post of yours from 6/15/10. That really makes it a lot easier to understand what’s happening! 5) I rebuilt Boost with the ODR code enabled. Results: I saw no ODR problems with the compile (by the time I did a full compile, I’d done steps 1-4). I saw none of the link warnings when rebuilding the DLL. I’m having much better success with the DLL now. It works almost completely. I’m now only having an RTTI issue that I’m working to resolve. I may post separately about that if my next few tests don’t identify the problem. PS –I’ve gotten pretty familiar with some parts the serialization code as I’ve stepped through it with the debugger. Very cool! It’s a real education on template meta-programming. Thanks for making this available and for doing such a great job with it both in terms of functionality and the artistry of the implementation. --- Steve H.

This code traps such violations but is commented out as too many users complained that it inhibited their programs from running. Try uncommenting this code, re-building the serialization library, and then rebuilding and re-running your DLL.

[Asio] deadline_timer doesn't fire in some cases
by Ionut Slaveanu 23 May '14

23 May '14

We have a client application that uses deadline_timers in order to implement timeouts for read and write operations on a socket. We have an io_service thread that runs boost::asio::io_service::run. The _ioService is used by resolver, by read, write, connect timers (implemented using deadline_timer) and also by tcp::socket. On socket we are using only synchronous operations like: connect, read_some, write_some. The socket is blocking. Also for resolver we are using the synchronous operation resolve. Our problem is that although read timer is set to 100 milliseconds, it doesn't fire up and the application is blocked in read_some function for like 15 minutes. In onReadTimeout callback we are closing the socket. I can reproduce this behavior every time by changing the connection settings on the virtual machine that host the server to a dummy interface. Currently I sow this behavior in logs and i did a core dump of the client process using gcore and sow the stack trace on all threads. I added also the stack trace. The thread that is blocked for 15 minutes is thread 18. This thread contain in stack trace boost::asio::io_service::run. Also thread 9 and thread 10 contains boost::asio::io_service::run. Thread 18 calls _readTimer.expires_from_now(boost::posix_time::milliseconds(_readTimeout), ec); _readTimer.async_wait(boost::bind(&BlockingTcpClient::onReadTimeout, this, boost::asio::placeholders::error)); with readTimeout set to 100 and then _pSocket->write_some. In BlockingTcpClient::onReadTimeout we are closing the socket. So read_some should be blocked for maximum 100 miliseconds. Maybe the problem is that the read timer uses the same io_service that currently is blocked in read_some. Can anyone help us to investigate or fix this issue? If this is a known limitation can anyone tell us why this behavior happen? Thank you!

[RegEx] Are there any tools to test a regular expression will work
by John Bryan 23 May '14

23 May '14

Specifically Boost "Perl Regular Expression Syntax" option (with or without Unicode enhancements) I am working with software a product that is using Boost regex engine but I need a way to test individual regex expressions before committing them in to it. But I have found there are operstors that I sometimes need to use that do not exist in any on-line or client-side regex tester/editor or IDE that I have tried. They all seem to be based on Java or .Net based regex engines and I can not find any that uses the Boost engine. Tried RegExPal, RegEx.Powertoy, NotePad++, Padre etc. I don't mind whether it is online, Windows based, Linux based (so long as easy to install) or part of a larger application (so long as not massive). I just want something that will take a few seconds to tell if a regular expression will match a particular text. Example Boost specific expression:- "(one) (two) (three) \g-1" should match on:- "one two three three" Regards, John ________________________________ Sophos Ltd, a company registered in England and Wales, number 2096520, The Pentagon, Abingdon Science Park, Abingdon, OX14 3YP, United Kingdom

[Graph] CSR from list of tuples
by Sensei 23 May '14

23 May '14

Dear all, I need to construct (and use) a graph that can handle millions of nodes, with minimal overhead, and as suggested I am using a CSR graph. As I understand from the documentation, it is unmodifiable. Arcs are created at runtime in a parallel fashion, and my choice was to use a vector of std::tuple<std::size_t, std::size_t, int> (that is, node, node, weight) with Intel's TBB. This is the problem: can I avoid temporary vectors to construct my graph? Right now the only way I see is to create the vector of arcs (as std::pair) and the vector of weights, but this is a waste of time and memory. Do you have any helpful suggestions? Cheers & Thanks!

Classification: Honeywell Internal Correction: I incorrectly stated below "the Microsoft compiler does create an executable that will execute static code that is not reachable via main ". That is wrong - the executable will *not* execute static code unless it is reachable via main. Hence my concern that the BOOST macros may be creating static code that doesn't get executed. --- Steve H. ============================================================================================================================================================================================================ This message classified as Honeywell Internal by Hickman, Steve (AdvTech) on Thursday, May 22, 2014 at 5:45:39 PM.

I have instances from a class hierarchy that I'm serializing through a base class pointer. I'm building a 32 bit debug console application. I'm serializing to an input text archive then extracting the stringstream and deserializing via an output text archive. When I build the library containing the class hierarchy as a static library, I can serialize and deserialize consistently instances of any of the classes in the hierarchy multiple times. When I build the same library as a DLL, serialization/ deserialization works for some of the classes but fails consistently when deserializing one of the derived classes. I've checked the following things: 1) All of the data fields of the instances are initialized. They are fundamental types (bool, int, long), std::string, a std::chrono (which has a serialization I found on the 'Net) and one enumerated type (removing the enumerated type doesn't fix the problem). 2) The serialize code is in the .cpp files (not headers) along with the instantiations for the archive I use so I don't have multiple instantiations of the serialize methods 3) The test driver does nothing but run the tests - so the DLL containing the library shouldn't be loaded multiple times. 4) The output archive is closed before I open the input archive, so there shouldn't be characters missing at the end of the stringstream. 5) I'm building UNICODE for both the library and the test driver, so character size shouldn't be changing. I know is that the Microsoft compiler does create an executable that will execute static code that is not reachable via main. I have not (to my knowledge) included static code that is unreachable via main, but I haven't delved into the Serialization EXPORT macros to see what exactly they are doing. I don't know if that is a source of the problem. When I build the library, I do get linker warnings (see examples at bottom) that I'm importing locally defined symbols. Since all of the classes in the library must be visible externally because they are used externally, they must all be exported. Since they are part of a class hierarchy, they must be available to the other classes in the library that derive from them. I don't know if these warnings point to the problem. I also don't know how to get rid of them given the above. My question is: Why is this happening? How do I fix it? Other notes: all of the library classes have "DECL" macros that resolve to __declspec(dllexport) or __declspec(dllimport) when building the dll.

[serialization] Works when statically linked but not as a DLL using VS2012 on Win7 64bit [Honeywell Internal]
by Hickman, Steve (AdvTech) 22 May '14

22 May '14

Classification: Honeywell Internal I'm using Boost.Serialization on a 64 bit Win7 machine using VS 2012. I have instances from a class hierarchy that I'm serializing through a base class pointer. I'm building a 32 bit debug console application. I'm serializing to an input text archive then extracting the stringstream and deserializing via an output text archive. When I build the library containing the class hierarchy as a static library, I can serialize and deserialize consistently instances of any of the classes in the hierarchy multiple times. When I build the same library as a DLL, serialization/ deserialization works for some of the classes but fails consistently when deserializing one of the derived classes. I've checked the following things: 1) All of the data fields of the instances are initialized. They are fundamental types (bool, int, long), std::string, a std::chrono (which has a serialization I found on the 'Net) and one enumerated type (removing the enumerated type doesn't fix the problem). 2) The serialize code is in the .cpp files (not headers) along with the instantiations for the archive I use so I don't have multiple instantiations of the serialize methods 3) The test driver does nothing but run the tests - so the DLL containing the library shouldn't be loaded multiple times. 4) The output archive is closed before I open the input archive, so there shouldn't be characters missing at the end of the stringstream. 5) I'm building UNICODE for both the library and the test driver, so character size shouldn't be changing. I know is that the Microsoft compiler does create an executable that will execute static code that is not reachable via main. I have not (to my knowledge) included static code that is unreachable via main, but I haven't delved into the Serialization EXPORT macros to see what exactly they are doing. I don't know if that is a source of the problem. When I build the library, I do get linker warnings (see examples at bottom) that I'm importing locally defined symbols. Since all of the classes in the library must be visible externally because they are used externally, they must all be exported. Since they are part of a class hierarchy, they must be available to the other classes in the library that derive from them. I don't know if these warnings point to the problem. I also don't know how to get rid of them given the above. My question is: Why is this happening? How do I fix it? Other notes: all of the library classes have "DECL" macros that resolve to __declspec(dllexport) or __declspec(dllimport) when building the dll. When I build the static library, these resolve to "" (nothing). I'm attaching copies of relevant files. All files named "Raw*Event" are part of the library. MinimalTest.cpp is the test driver. Chrono.hpp is the serialization header that is not part of the Boost serialization library.

boost::throw_exception(...) behaviour and use case
by Arindam Mukherjee 22 May '14

22 May '14

I was wondering what behaviour or idiom does boost::throw_exception enable. I must be dense but the documentation here (http://www.boost.org/doc/libs/1_55_0/libs/exception/doc/throw_exception.html) does not immediately ring a bell. Is it meant to somehow help write code that runs both in environments where exceptions are enabled and where they are not? Since the structure of code that does not use exception handling tends to be quite different from that which does, I was wondering what's a correct idiomatic use of Boost. Of course I am aware that my basic assumption might be incorrect. Thanks, Arindam

[units] Problem with conversion of compound units
by Norman, Ben 22 May '14

22 May '14

First, thanks for the most excellent boost::units library. We are making good use of it in a scientific software project. I confess that there more than a few things that remain mysterious to me, but I'll focus on one example here: ---------------------------------------------------------------- #include <iostream> #include <boost/units/make_scaled_unit.hpp> #include <boost/units/systems/si.hpp> using namespace std; using namespace boost::units; /** @brief electron volts */ struct ev_base_unit : public base_unit<ev_base_unit, energy_dimension, 9999>{ /** @brief Get the unit name */ static const char* name() { return "electron-Volt"; } /** @brief Get the unit symbol */ static const char* symbol() { return "eV"; } }; typedef ev_base_unit::unit_type ev_unit; BOOST_UNITS_STATIC_CONSTANT(eV, ev_unit); // keV typedef make_scaled_unit<ev_unit, scale<10, static_rational<3> > >::type kev_unit; BOOST_UNITS_STATIC_CONSTANT(keV, kev_unit); // can only define conversion from a base unit. BOOST_UNITS_DEFINE_CONVERSION_FACTOR(ev_base_unit, si::energy, double, 1.60217653e-19); // without this, conversion from si::energy to eV doesn't work BOOST_UNITS_DEFAULT_CONVERSION(ev_base_unit, si::energy); int main(int argc, char **argv){ // "natural" direction (ev -> joule) cerr << "conversion ev to joule: " << conversion_factor(eV, si::joule) << endl; cerr << "conversion kev/s to joule/s: " << conversion_factor(keV/si::second, si::joule/si::second) << endl; // "reverse" direction (joule -> ev) cerr << "conversion joule to ev: " << conversion_factor(si::joule, eV) << endl; cerr << "conversion from joule/s to kev/s: " << conversion_factor(si::joule/si::second, keV/si::second) << endl; // eV to keV conversions cerr << "conversion ev to kev: " << conversion_factor(eV, keV) << endl; cerr << "conversion ev/s to kev/s: " // Fails to compile: << conversion_factor(eV/si::second, keV/si::second) << endl; return 0; } ---------------------------------------------------------------- When compiling the program above with gcc 4.8.2 and boost 1.54, I get the error below. All the conversions for eV and keV to and from joules work fine (even when divided by time as a test), but going between eV/second and keV/second explodes. Is this a limitation of make_scaled_unit? I have also tried with scaled_base_unit, but the results are the same.
