Pid

Create pid files

To create PID files, use the create_pid_file(name, quantity) method:

• name – a unique identifier for the PID file set.

• quantity – the maximum number of allowed PID files.

from kcode.utils.pid import Pid

Pid("app_name", quantity=2).create_pid_file()

Get pid files

To retrieve a list of PID files, use the get_pid_files() method.

from kcode.utils.pid import Pid

Pid("app_name").get_pid_files()

Delete pid files

To delete PID files, use the delete_pid_files(pid_files) method, where pid_files is a list returned from get_pid_files().

from kcode.utils.pid import Pid

pid_files = Pid("app_name").get_pid_files()
Pid("app_name").delete_pid_files(pid_files)

Check if pid exists

To check whether a process is running, use the static method Pid.check(pid).

from kcode.utils.pid import Pid

Pid.check(12345)

Kill process

To kill a process by PID, use the static method Pid.kill(pid).

from kcode.utils.pid import Pid

Pid.kill(12345)
