Is there a memory leakage in this embedded python code?
Hi All,
I am working on embedded python on C these days. I feel there is a
memory leakage in this code. I have used our own memory pool and all
the python code will use the heap from this memory pool.
RunScript(pScriptName,pFuncName,...)
{
PyEval_AcquireLock()
threadState = Py_NewInterpreter();
PyThreadState_Swap(threadState);
/* Import the script module and run the fnc in that script module */
Pyobject *pModule = PyImport_Import(pScriptName);
PyObject *pFunc = PyObject_GetAttrString(pModule, pFuncName);
/* End running the script and calling the script fnc */
Py_EndInterpreter(threadState);
PyEval_ReleaseLock();
}
Befor running this code i checked my memory heap pool available
memory. Then i called the above function to run my script script1.py.
Script ran succesfully, but after completion of the above fnc, when i
checked the memory there is a huge KB of memory is used by this code.
I have no doubt on my memory pool implementation, bcoz it isworking
from many years.
Now, My doubt is, when i call Py_EndInterpreter at the end does it not
clear the whole memory which was used in executing the script? Or
still the imported stuff from the script1.py is in memory only?
Would greatly appreciate the help

Problem with pexpect when executing a command on a remote machine
Hi,
I am trying to execute a command on a remote machine for which I am using
Python pexpect module. Iam able to connect and copy files to the remote
machine but getting the following error when trying to execute commands on
the remote machine. Please find the below error.
''Error sending command: cluster config -r -a Timeout exceeded in

If we notice the error, the command is getting properly executed and the
output is also fetched but it returning a TIMEOUT error in
read_nonblocking() function of pxssh.py file of the pexpect module.
Please let me know how can I avoid this. Even the error is not consistent,
sometimes I am able to execute properly but it is failing most of the times.
Kindly reply me as soon as possible.
Thanks in advance.
Regards,
Kiran

Re: implementing SFTP using Python
@Ben Finney I have downloaded paramiko-1.6 package, pcrypto 2.0.1 package platform: windows XP Now Iam trying to run the demo scripts available with paramiko package.

You will probably want to investigate the "paramiko" package, a pure-Python implementation of the SSH2 protocol. - The fish are biting. Get more visitors on your site using Yahoo!

copying only recent files from one machine to another
Hi Everybody, Iam trying to copy files from one machine to another over SFTP connection. For that Iam using sftp.get & sftp.put methods. Now, I have to copy only recently created/modified files,i.e, based on timestamps from remote machine to my machine. Is there any standard implementation for that in python/paramiko ? If not , can anyone suggest me the efficient method to implement the same. Thanks in Advance, Kiran Kumar - No need to miss a message. Get email on-the-go with Yahoo! Mail for Mobile.
