Package: python2.5 Version: 2.5.4-1 Severity: normal Tags: patch As a result of i/o buffering, pdb is unable to debug some programs:
$ cat foo
#!/usr/bin/python
import os
for i in range(1001):
pass
os._exit(1)
$ yes s | pdb foo | tail | grep .
(Pdb) > /tmp/foo(5)<module>()
-> for i in range(1001):
(Pdb) > /tmp/foo(6)<module>()
-> pass
(Pdb) > /tmp/foo(5)<module>()
-> for i in range(1001):
(Pdb) > /tmp/foo(6)<module>()
-> pass
(Pdb) > /tmp/foo(5)<module>()
-> for i in range(100
$
(See #529429 for a real world example. PYTHONUNBUFFERED can be used as a
workaroud. Output is not necessarily deterministic.)
Please flush the output buffer on prompt. The attached patch fixes the problem.
