This is on windows with python 2.6.
I can't seem to remove a possibility of a deadlock in one of my
scripts at the moment. Its not a constant deadlock but it appears
from time to time. The code is below:
try:
process =
subprocess.Popen(cmd,stdout=subprocess.PIPE,stderr=subprocess.STDOUT)
NotDone = True
data = []
while NotDone:
NotDone = False
result = process.poll()
if result == None:
NotDone = True
if NotDone:
out, err = process.communicate()
Log(out)
I was able to get the program to write out the stack trace for my
threads and it is usually deadlocked on sys.stdout.read or
_internal_poll of subproceess.
I've even tried the above, with using "with
tempfile.NamedTemporaryFiles() as buff:" and writing to the file, but
it still deadlocks. In the past I work around this by running fewer
processes asynchronously but I would really like to get this solved so
I don't have to wait to see if it'll be caused with any changes I
make.
Any tips would be appreciated.
