| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent failure observed on OpenBSD led me to an interesting consideration. ``` ====================================================================== ERROR: psutil.tests.test_process.TestProcess.test_long_name ---------------------------------------------------------------------- Traceback (most recent call last): File "/vagrant/psutil/psutil/_psbsd.py", line 566, in wrapper return fun(self, *args, **kwargs) File "/vagrant/psutil/psutil/_psbsd.py", line 684, in cmdline return cext.proc_cmdline(self.pid) ProcessLookupError: [Errno 3] No such process During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/vagrant/psutil/psutil/tests/test_process.py", line 751, in test_long_name self.assertEqual(p.name(), os.path.basename(testfn)) File "/vagrant/psutil/psutil/__init__.py", line 628, in name cmdline = self.cmdline() File "/vagrant/psutil/psutil/__init__.py", line 681, in cmdline return self._proc.cmdline() File "/vagrant/psutil/psutil/_psbsd.py", line 569, in wrapper raise ZombieProcess(self.pid, self._name, self._ppid) psutil.ZombieProcess: PID still exists but it's a zombie (pid=48379) ---------------------------------------------------------------------- ``` The exception above occurs sporadically. 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. Not on OpenBSD but on all platforms. Signed-off-by: Giampaolo Rodola <g.rodola@gmail.com>

* Fix Linux test: allow '-dirty' or other version postfixes (#2221)Mark Asselstine2023-04-051-1/+1
| | | | | | | | | | | | | | | | | It is possible that 'free -V' will return a version that includes a postfix such as '-dirty'. For example procps-ng will explicitly add this when building from git: https://gitlab.com/procps-ng/procps/-/blob/master/local/git-version-gen#L154 Process the version string to drop these string postfixes from the version tuple, failing to do so will result in the test failing File ".../psutil/tests/test_linux.py", line 204, in get_free_version_info return tuple(map(int, out.split()[-1].split('.'))) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ValueError: invalid literal for int() with base 10: '3-dirty' Signed-off-by: Mark Asselstine <mark.asselstine@windriver.com>

* When raising warning, always use stacklevel=2Giampaolo Rodola2023-03-271-2/+2
| | | | | | | | | | B028: No explicit stacklevel argument found. The warn method from the warnings module uses a stacklevel of 1 by default. This will only show a stack trace for the line on which the warn method is called. It is therefore recommended to use a stacklevel of 2 or greater to provide more information to the user.

* Win: fix running tests in a virtual environment (#2216)Matthieu Darbois2023-03-274-18/+30
| | | | | | | | | | | | On windows, starting with python 3.7, virtual environments use a venvlauncher startup process This does not play well when counting spawned processes or when relying on the pid of the spawned process to do some checks e.g. connection check per pid This commit detects this situation and uses the base python executable to spawn processes when required.

* CI: fix TestScripts tests failing due to ambiguous SCRIPTS_DIR (#2211)Matthieu Darbois2023-03-181-1/+4
| | | | | | | | | | | | Tests are being run with psutil installed in a virtual environment within cibuildwheel builds. The scripts folder is not being found in this installation & thus, those tests are skipped. This commit allows to pass the path of the scripts folder through an environment variable & re-enables those tests. Signed-off-by: mayeut <mayeut@users.noreply.github.com>
