serialization: file written with 1.34.1 can't be read in with 1.35

[filippeters@…]

std::vectors of basic types, saved with 1.34.1, can't be read by 1.35:

simple sample, write file with 1.34.1:

std::vector<unsigned int> vectorToSave; vectorToSave.push_back(0); vectorToSave.push_back(1); vectorToSave.push_back(2);

std::string filename("C:
test1341.xml");

{

std::ofstream ofs(filename.c_str()); assert(ofs.good()); boost::archive::xml_oarchive oa(ofs); oa << BOOST_SERIALIZATION_NVP(vectorToSave);

}

And with 1.35:

std::vector<unsigned int> vectorToLoad;

std::string oldfilename("C:
test1341.xml");

try{

std::ifstream ifs(oldfilename.c_str()); assert(ifs.good()); boost::archive::xml_iarchive ia(ifs);

restore the schedule from the archive ia >> BOOST_SERIALIZATION_NVP(vectorToLoad);

} catch(...){

std::cout << "\nproblem";

}

This will end up in the catch.

sample output from 1.34:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <boost_serialization signature="serialization::archive" version="4"> <vectorToSave>

<count>2</count>

<item_version>0</item_version>

<item>0</item> <item>1</item>

</vectorToSave> </boost_serialization>

sample output from 1.35:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <boost_serialization signature="serialization::archive" version="4"> <vectorToSave>

<count>2</count> <item>0</item> <item>1</item>

</vectorToSave> </boost_serialization>

Notice the missing <item_version>0</item_version>
