详细描述
Class Signal implements signal handling to e.g. allow ctrl+c to cancel a long running process.
This is done in two ways:
- A signal handler is attached to trap the SIGINT and SIGURG signal. Pressing ctrl+c or sending the SIGINT (kill ...) signal to the shogun process will make shogun print a message asking to immediately exit the running method and to fall back to the command line.
- When an URG signal is received or ctrl+c P is pressed shogun will prematurely stop a method and continue execution. For example when an SVM solver takes a long time without progressing much, one might still be interested in the result and should thus send SIGURG or interactively prematurely stop the method
