refactor: always call setsid for exec processes#138
Merged
Conversation
Ensure every exec process starts in a new session to achieve: - Isolation: Decouples the process from the caller's session and controlling terminal to prevent unexpected signal propagation. - Security: Mitigates TIOCSTI terminal injection attacks by ensuring the process has no terminal to push characters back to. - TTY Setup: Provides the required clean state for the process to properly acquire its own PTY if terminal=true.
