Hi, psphere: Python interface for the VMware vSphere Web Services SDK
I already developed an app using https://bitbucket.org/jkinred/psphere. But getting lot of errors since psphere is not thread safe (I think). So i wrote couple of scripts to test it (See attached files) and found that caching mechanism used by psphere is not thread safe. Could someone please give me some suggestion to make it thread safe. =======Test Code ======== import psphere from psphere.client import Client from psphere.managedobjects import HostSystem, VirtualMachine, ComputeResource client = Client("192.168.0.114", "root", "vmware1") ##vCenter print "\nSucessfully connected to vCenter.\n" from threading import Thread def myfunc(i): host1 = HostSystem.get(client, name="192.168.0.134") host2 = HostSystem.get(client, name="192.168.0.113") print "----i------",i while True: #host1.update(properties=["config", "vm"]) #host2.update(properties=["config", "vm"]) c = type(host1.config.network) v = type(host2.config.network) for vm in host1.vm: k = vm.config.template for vm in host2.vm: p = vm.config.template for i in range(10): t = Thread(target=myfunc, args=(i,)) t.start() """ OUTPUT ======= Sucessfully connected to vCenter. ----i------ 1 ----i------ 3 ----i------ 5 ----i------ 0 ----i------ 4 ----i------ 2----i------ 7 ----i------ 9 ----i------ 6 ----i------ 8 Exception in thread Thread-4: Traceback (most recent call last): File "/usr/lib/python2.7/threading.py", line 551, in __bootstrap_inner self.run() File "/usr/lib/python2.7/threading.py", line 504, in run self.__target(*self.__args, **self.__kwargs) File "vcenter_test1.py", line 19, in myfunc k = vm.config.template File "/home/saju/cvt/trunk/src/cvt/web/cvt/psphere/__init__.py", line 79, in __get__ value = self.fget(inst) File "/home/saju/cvt/trunk/src/cvt/web/cvt/psphere/managedobjects.py", line 1236, in config return self._get_dataobject("config", False) File "/home/saju/cvt/trunk/src/cvt/web/cvt/psphere/__init__.py", line 116, in _get_dataobject return self._cache[name][0] KeyError: 'config' Exception in thread Thread-6: Traceback (most recent call last): File "/usr/lib/python2.7/threading.py", line 551, in __bootstrap_inner self.run() File "/usr/lib/python2.7/threading.py", line 504, in run self.__target(*self.__args, **self.__kwargs) File "vcenter_test1.py", line 17, in myfunc v = type(host2.config.network) AttributeError: VirtualMachineConfigInfo instance has no attribute 'network' """ -- http://mail.python.org/mailman/listinfo/python-list
