Description Xavier Bachelot 2017-08-09 10:05:17 UTC

Description of problem:
We are using the python-psutil package on EL6 and are frequently encountering the following error :

Traceback (most recent call last):
File "/tmp/ansible_6ujUs4/ansible_module_wait_for.py", line 34, in
import psutil
File "/usr/lib64/python2.6/site-packages/psutil/__init__.py", line 64, in
import psutil._pslinux as _psplatform
File "/usr/lib64/python2.6/site-packages/psutil/_pslinux.py", line 86, in
_TERMINAL_MAP = _psposix._get_terminal_map()
File "/usr/lib64/python2.6/site-packages/psutil/_psposix.py", line 116, in _get_terminal_map
ret[os.stat(name).st_rdev] = name
OSError: [Errno 2] No such file or directory: '/dev/pts/0'


Version-Release number of selected component (if applicable):
python-psutil-0.6.1-1.el6

How reproducible:
Not always, but very frequently.


I've taken a look at upstream bug tracker and it seems to be :
https://github.com/giampaolo/psutil/issues/341
which is fixed in this commit :
https://github.com/giampaolo/psutil/commit/5b50df569558456bccde708ee478681673701dae
so I believe this is fixed in psutil 0.7.0

In order to try and fix the bug on our side, I rebuilt an rpm based on the epel7 branch, which currently ships python-psutil 2.2.1.
This cured the bug for us.

So, could you please update the el6 branch to match what's in the epel7 branch ?

Regards,
Xavier

Comment 1 Xavier Bachelot 2017-11-28 11:39:10 UTC

gentle ping. We've been using the locally updated python-psutil 2.2.1 package on EL6 with no issue for several months.

Comment 2 Fedora Update System 2017-11-30 21:37:02 UTC

python-psutil-2.2.1-1.el6 has been submitted as an update to Fedora EPEL 6. https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2017-1290b498a8

Comment 3 Fedora Update System 2017-12-02 08:31:43 UTC

python-psutil-2.2.1-1.el6 has been pushed to the Fedora EPEL 6 testing repository. If problems still persist, please make note of it in this bug report.
See https://fedoraproject.org/wiki/QA:Updates_Testing for
instructions on how to install test updates.

Comment 4 Vincent Brillault 2017-12-08 13:20:36 UTC

python-psutil 2.2.1 is a huge (incompatible) jump in version from 0.6.1, in particular with regard to the Process.{,set_}{,io}nice API:
* In 0.6.1, Process.{,io}nice are deprecated properties and Process.{get,set}_{,io}nice should be used to get and change the {,io}nice
* In 2.2.1, Process.{,io}nice are methods and Process.{get,set}_{,io}nice are deprecated and raise a warning

Here are two reproducers:
```
python -c "import os;import psutil; p = psutil.Process(os.getpid()); p.set_nice(18); p.set_ionice(psutil.IOPRIO_CLASS_BE, 6)"
python -c "import os;import psutil; p = psutil.Process(os.getpid()); p.nice(18); p.ionice(psutil.IOPRIO_CLASS_BE, 6)"
```

* When using 0.6.1, the 1st works properly and the 2nd results in:
```
-c:1: DeprecationWarning: this property is deprecated; use Process.get_nice() method instead
Traceback (most recent call last):
  File "<string>", line 1, in <module>
TypeError: 'int' object is not callable
```

* When using 2.2.1, the 2nd works properly and the 1st results in:
```
-c:1: DeprecationWarning: set_nice() is deprecated; use nice() instead
-c:1: DeprecationWarning: set_ionice() is deprecated; use ionice() instead
```

This message is a reminder that EPEL 6 is nearing its end of life. Fedora will stop maintaining and issuing updates for EPEL 6 on 2020-11-30. It is our policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of 'el6'.

Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later EPEL version.

Thank you for reporting this issue and we are sorry that we were not able to fix it before EPEL 6 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged  change the 'version' to a later Fedora version prior this bug is closed as described in the policy above.

Comment 6 Ben Cotton 2020-11-30 15:57:33 UTC

EPEL el6 changed to end-of-life (EOL) status on 2020-11-30. EPEL el6 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
EPEL please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
