Summary: subprocess.Popen fails with closed stdout
Initial Comment:
I have a piece of code that gets run in a script that
has its stdout closed:
import sys
sys.stdout = sys.stderr
c = subprocess.Popen (...,
stdin = subprocess.PIPE,
stdout = subprocess.PIPE,
stderr = subprocess.STDOUT)
and this is what I get:
Sending SVNR/permissions
Transmitting file data .svn: Commit failed (details
follow):
svn: 'pre-commit' hook failed with error output:
Traceback (most recent call last):
(...)
File ".../__init__.py", line 40, in run
stderr = subprocess.STDOUT)
File "/usr/local/lib/python2.4/subprocess.py", line
554, in __init__
errread, errwrite)
File "/usr/local/lib/python2.4/subprocess.py", line
986, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
This is the child_traceback:
File "/usr/local/lib/python2.4/subprocess.py", line
955, in _execute_child
File "/usr/local/lib/python2.4/os.py", line 341, in
execvp
File "/usr/local/lib/python2.4/os.py", line 379, in
_execvpe
func(fullname, *argrest)
OSError: [Errno 2] No such file or directory
http://docs.python.org/lib/node230.html claims that
"PIPE indicates that a new pipe to the child should be
created" which doesn't seem to be the case.
Subversion code that runs the script can be seen at
http://svn.collab.net/viewcvs/svn/trunk/subversion/libsvn_repos/hooks.c
(run_hook_cmd()).
