I use os.system invoking java VM, when running in python thread,
the java application crashes. But it works properly when thread is
not used.
Has any body come across with this problem?
Python 2.3.3
J2SDK 1.4.2_05
SuSE Linux Enterprise Server 9
The following is source file:
#!/usr/bin/env python
import os, sys, threading
class ThreadTask(threading.Thread) :
def __init__(self, shellcmd) :
threading.Thread.__init__(self)
self.command = shellcmd
def isStopped(self) :
self.join(0.01)
return not self.isAlive()
def run(self) :
os.system(self.command)
def test() :
commands = [
"/usr/lib/java/bin/javac",
"/usr/lib/java/bin/java",
]
tasks = []
for a in commands :
tasks.append(ThreadTask(a))
for a in tasks :
a.start()
endcnt = 0
while endcnt < len(tasks) :
endcnt = 0
for a in tasks :
if a.isStopped() : endcnt += 1
print("DONE")
test()
