New submission from François Granade <[email protected]>:
If I remove the "proc2.stdin.close()" in the script below, the
"proc1.wait()" will hang. Tested on MacOS, Linux, CygWin on 2.5.2 and
2.6. Is it a bug ?
from subprocess import Popen, PIPE
proc1 = Popen('cat -', shell=True, stdin=PIPE, stdout=PIPE)
proc2 = Popen('cat -', shell=True, stdin=PIPE, stdout=PIPE)
# Removing this line make the proc1.wait() hang
proc2.stdin.close()
proc1.stdin.close()
proc1.wait()
