gt<> sets a maximum numeric limit to std::numeric_limits<int>::max() instead of std::numeric_limits<int64_t>::max()

[AugusteBourgois]

Hi everyone,

I came across the following bug:

When using the gt<> parameter validator, I checked the source code generated, and it seems that when using gt<> on an integer (ros parameter type) the parameter created is of type int64_t, which is expected, but the maximum value is set to std::numeric_limits::max().
There is a similar problem with lt<>.

I guess this is not the desired behavior.

This can be seen in the generated admittance_controller_parameters.hpp file, line 1072..1091 :

if (!parameters_interface_->has_parameter(prefix_ + "lt_eq_fifteen")) {
          rcl_interfaces::msg::ParameterDescriptor descriptor;
          descriptor.description = "should be a number less than or equal to 15";
          descriptor.read_only = false;
          descriptor.integer_range.resize(1);
          descriptor.integer_range.at(0).from_value = std::numeric_limits<int>::lowest();
          descriptor.integer_range.at(0).to_value = 15;
          auto parameter = to_parameter_value(updated_params.lt_eq_fifteen);
          parameters_interface_->declare_parameter(prefix_ + "lt_eq_fifteen", parameter, descriptor);
      }
      if (!parameters_interface_->has_parameter(prefix_ + "gt_fifteen")) {
          rcl_interfaces::msg::ParameterDescriptor descriptor;
          descriptor.description = "should be a number greater than 15";
          descriptor.read_only = false;
          descriptor.integer_range.resize(1);
          descriptor.integer_range.at(0).from_value = 15;
          descriptor.integer_range.at(0).to_value = std::numeric_limits<int>::max();
          auto parameter = to_parameter_value(updated_params.gt_fifteen);
          parameters_interface_->declare_parameter(prefix_ + "gt_fifteen", parameter, descriptor);
      }
