Description
Interrupting a Process with TTY mode in a Command leads to broken terminal: we can't see what we're typing anymore.
It happens only for processes that require user input several times. The bug occurs if there are remaining steps to complete the operation. So if we interrupt the process at the last step, bug doesn't occur.
Typically, my use case is using Maker Bundle. So for instance, bug occurs with make:entity, but not with make:controller.
How to reproduce
- Make a basic command with
make:commandor manually. - Implement
SignalableCommandInterfaceand susbcribe to SIGINT signal. - Run a Process that require user input multiple times with TTY mode enabled in execute command function, like this:
$process = Process::fromShellCommandline('php bin/console make:entity');
$process->setTty(true);
$process->run();- Run command at the project root (
php bin/console your-command). - Interrupt command at the first step.
- See that you can't see what you're typing anymore in the terminal (but you're typing!).
Possible Solution
It should be a problem with standard input/output not given back to the parent process, but I don't have enough knowledge in systems to fix it alone...
Additional Context
As you can see, you don't see the php -v I entered after interrupting the Test command that launches make:entity process. Only the result of it appears.
