Slow parsing of very long flow-style lines #289
Description
When parsing a large 34MB file, it seems stuck in an infinite loop (waited 5 minutes). This file is almost the same as the one from #288 except that it has 500 flow style sequences of 10 000 floats each instead of a block style. The block style file takes less then a second to load... I'm using 17 precision floats (which are doubles) and used the ryml::_WIP_STYLE_FLOW_SL for generating the file.
Step to reproduce:
std::string loadFileToString(const std::string& path)
{
std::ifstream ifs(path.c_str(), std::ios::in | std::ios::binary | std::ios::ate);
std::ifstream::pos_type size = ifs.tellg();
ifs.seekg(0, std::ios::beg);
std::vector<char> bytes(size);
ifs.read(bytes.data(), size);
std::cout << "Read bytes finished" << std::endl;
return std::string(bytes.data(), size);
}
int main()
{
std::string path = "your_path";
std::string buf = loadFileToString(path);
ryml::Tree t;
ryml::NodeRef n = t.rootref();
// not tested with parse_in_place
ryml::parse_in_arena("flow.yaml", ryml::to_csubstr(buf), n);
}
