[issue11650] CTRL-Z causes interpreter exit

Charles-Francois Natali added the comment: my_fgets in Parser/myreadline.c is broken: There's a comment saying that a fgets is retried on EINTR, but the code doesn't retry. It used to in older cPython versions, but there was also a bug, so my guess is that this bug has been here for a long tim

Davide Rizzo added the comment: You are right. The previous runs were without readline. With readline it behaves as expected. For the sake of completeness, here's the output of your snippet after Ctrl+Z, fg: getchar: Interrupted system call -- ___

[issue11650] CTRL-Z causes interpreter exit

Charles-Francois Natali added the comment: In that case, it's likely due to the way OS-X handles interrupted syscalls. Under Linux, getchar and friends (actually read with default SA_RESTART) won't return EINTR on (SIGSTOP|SIGTSTP)/SIGCONT. Under OS-X, it seems that e.g. getchar (read) does ret

[issue11650] CTRL-Z causes interpreter exit

Steffen Daode Nurpmeso added the comment: The exit status code is always 0. It seems to me somewhere in a run() somebody sets some 'do exit' and thus causing a normal exit. But i really can't find something down in pythonrun.c at a short glance (and i just dived shallow into Python yet), and

Charles-Francois Natali added the comment: I'm still not sure I understand the problem. - when you hit CTRL-Z, the process is put in background, since it receives a SIGTSTP : normal - when you put it in foreground with 'fg', it doesn't resume ? Did you try to hit to have sys.ps1 '>>> ' printe

Charles-Francois Natali added the comment: What's the problem here ? CTRL-Z causes the controlling terminal to send a SIGTSTP to the process, and the default handler stops the process, pretty much like a SIGSTOP. If you don't want that to happen: import signal signal.signal(signal.SIGTSTP, sign
