[Quickfix-developers] Found checksum problem

[Jo J. <jo...@tr...>]

I found the cause of my checksum problem: the setString() function on
the field class does not reset the m_total member before adding to it:
 
void setString( const std::string& string )
  { 
    m_string = string;
    m_data = IntConvertor::convert(m_field) + "=" + string + "\001";
    m_length = m_data.length();
    const char* iter = m_data.c_str();
    const char* end = iter + m_data.length();
    while( iter != end )
      m_total += *iter++;
  }
 
My suggestion is that a line be added as such:
 
void setString( const std::string& string )
  { 
    m_string = string;
    m_data = IntConvertor::convert(m_field) + "=" + string + "\001";
    m_length = m_data.length();
    const char* iter = m_data.c_str();
    const char* end = iter + m_data.length();
    m_total = 0;
    while( iter != end )
      m_total += *iter++;
  }
