Hi, Does ROS or ROS2 have a limit on the maximum length a log message can have?

I would assume something like https://en.cppreference.com/w/cpp/str.... For ROS1 internally https://logging.apache.org/log4cxx/la... is used thus I would assume you could use the maximum string size. Yet I would not recommend this.

Do you have a bug where you expect this to be an issue?

What is the use case you have in mind where such a limit could play a role?

I don't have a specific use case or problem. Just curios that ROS IDL string type does not have a limit specifier. And it was not clear to me what would happen if I pass a very long log string.
