From 19461905377ce3060b60df1949c082086492dab9 Mon Sep 17 00:00:00 2001 From: Giampaolo Rodola Date: Fri, 14 Apr 2023 21:38:07 +0000 Subject: [PATCH 01/22] Fix #2236 / NetNBSD: skip terminated process threads Process threads() and num_threads() methods now skip threads which are in ZOMBIE or IDLE state. It turns out that after a thread is terminated / join()ed, instead of disappearing it can stick around in a ZOMBIE or IDLE state, presumably for a while before being garbage collected.

It originates from `sysctl (KERN_PROC_ARGV)`: https://github.com/giampaolo/psutil/blob/0a81fa089fd4b25b4b7ee71ed39213b83f73c052/psutil/arch/openbsd/proc.c#L149 The error per se does not represent a bug in the OpenBSD `cmdline ()` implemention because the process **really** is a zombie at that point (I'm not sure why it's a zombie - this seems only to occur only on OpenBSD for this specific test case - but that's not the point). The interesting thing is that the test calls process `name()` (which succeeds, despite it's a zombie process), but since the process name is too long it gets truncated to 15 chars (this is a UNIX thing) so psutil tries to guess the remaining characters from the process `cmdline()`, which fails: https://github.com/giampaolo/psutil/blob/0a81fa089fd4b25b4b7ee71ed39213b83f73c052/psutil/__init__.py#L623-L630 The problem to fix here is that, if `name()` succeeds but `cmdline()` fails, we should not raise `ZombieProcess`: we should simply return the (truncated) process `name()` instead, because that is better than nothing.
