This tiny program hangs:
================================================== ======================
#!/usr/bin/env python
import subprocess
a = subprocess.Popen('cat',shell = True,stdin = subprocess.PIPE,
stdout = subprocess.PIPE)
b = subprocess.Popen('cat >/dev/null',shell = True,stdin = a.stdout)
a.stdin.close()
b.wait() # hangs
a.wait() # never reached
================================================== ======================
It shouldn't, should it?
Environment:
================================================== ======================
Python 2.5.1 (r251:54863, Jun 20 2007, 12:14:09)
[GCC 4.1.2 20061115 (prerelease) (SUSE Linux)] on linux2
