kill-process

问题 How I can deallocate resources when the process gets killed by, for example, the Task Manager? Is there a way to call a function before the process gets closed? 回答1: There really is nothing you can do if your process is killed. By definition, killing a process is just that - killing it. The process does not get an opportunity to run any code. This is very much "by design". Imagine that you could register a routine that was called when your process was killed by the user (or by another process

问题 i am using MULTIPROCESSING to find my requirement. And when that runs i am getting a pid(may be parent! i don't know what to call that) then co processes with their own pid and reference id of first process. Now i need to kill all those processes BY ONLY KILLING THE FIRST PROCESS then which will be the best way to do that. THAT ALSO IN PYTHONIC WAY.

问题 I read the documentation for oci_cancel but it seems to me a bit fuzzy. Does oci_cancel kill the sql process in the server? If not, how can I make a script that executes a sql query, waits a moment and if the query exceeds 10 seconds (for example), cancel the query in the server? Excuse me if this question is similar to one that has been asked time ago, but I didn't find any satisfactory answer. 回答1: PDO allows you to specify the query timeout with the "ATTR_TIMEOUT" attribute, although it's

问题 I am using python multiprocessing to split one of the longer processes and run parallelly. It is working fine except when there is an exception in one of the child processes, in which case, process pool is not closed and I can still see those processes on the server. Here is the code: from multiprocessing import Pool pool = Pool(processes=4) from functools import partial param_data = "Test Value" func = partial(test_function, param_data) r = pool.map(func, range(3)) pool.close() def test

问题 I want to log if a customer tries to force close the application. I'm aware of having no chance to catch a process kill. But it should be possible through the main form closing event to get informed about the 'CloseReason.TaskManagerClosing' reason. But any tests I did under Windows 8.1 I always got a CloseReason.UserClosing reason. But in this case (compared to a normals CloseReason.UserClosing) I've about 0.2s to run user code afterwards my program is killed! Is this a new behavior in
