Logged In: YES user_id=1038590 Python's C main function assumes stdin, stdout and stderr are all valid FILE pointers. A little experimentation on a Linux box should establish what glibc is providing when the input pipe isn't a proper file (probably stdin == NULL given the symptoms, but that's just a guess) A sanity check on stdin should then be possible near the start of the main function. |

Logged In: YES user_id=521 I doubt if libc checks whether the input is a directory; there are possible (though extremely obscure) cases where you might want to do that. I think you probably need something along the lines of fstat(0, &buf), then check the st_mode. Remember that fifos and chardevs ought to be allowed. |

Logged In: YES user_id=521 Here is another failure, which might have the same root cause: $ python /tmp $ echo $? 0 I'd expect this to give an error. |

Logged In: YES user_id=33168 I fixed this problem and also added a warning when passing a directory on the command line. Before the fix, python would just silently exit which just bit me recently. (Same as mbp's comment.) Checked in as: * Misc/NEWS: 1.1384, 1.1193.2.118 * Modules/main.c: 1.85, 1.84.2.1 * Python/sysmodule.c: 2.130, 2.126.2.4 * Lib/test/test_cmd_line.py: 1.1, 1.1.2.2 |
