sosreport: AttributeError: 'str' object has no attribute 'decode'

[bugproxy]

[impact]

sosreport plugin(s) fail

[test case]

run sosreport, then extract the captured report and check the sos_logs/logs-plugin-errors.txt file for output like:

Traceback (most recent call last):
  File "/usr/share/sosreport/sos/sosreport.py", line 1300, in collect
    plug.collect()
  File "/usr/share/sosreport/sos/plugins/__init__.py", line 877, in collect
    self._collect_strings()
  File "/usr/share/sosreport/sos/plugins/__init__.py", line 860, in _collect_strings
    (content.splitlines()[0]).decode('utf8', 'ignore'))
AttributeError: 'str' object has no attribute 'decode'

one of the ways to trigger this is for sosreport to gather a file that is larger than its max size to gather, for example log files over its --log-size limit. To reproduce this way, first make sure one or more of the sosreport-gathered log files are over 1m, e.g. on a newly-installed system (where log files are small) you could do this just to generate logs:

# udevadm control -l 7
# for n in $( seq 1 50 ) ; do udevadm trigger ; done

after that, /var/log/syslog should be larger than 1m. Then run sosreport and limit its log file size to 1m:

# sosreport --log-size 1

The resulting sosreport will contain the error while trying to gather the syslog.

[regression potential]

the currently failing plugins fail to gather any of their data, so there is not much regression for them, but this change has the potential to affect any plugin and prevent data gathering.

that commit is already included in the sosreport version being used, so it does not seem it will fix this.

[Dan Streetman (ddstreet)]

<email address hidden> I can't reproduce this on x86, does this happen on all ppc64le systems or only on specific system(s) you have? Can you provide the sosreport generated with that error?

[Dan Streetman (ddstreet)]

I did find an existing sosreport I have that includes this error; I'll look at the code to see what's going on.

[Dan Streetman (ddstreet)]

Opened github sosreport issue 1266 for this
https://github.com/sosreport/sos/issues/1266

Also opened pull request 1267 to fix

[Dan Streetman (ddstreet)]

<email address hidden> I built a test sosreport package for Xenial in this ppa:
https://launchpad.net/~ddstreet/+archive/ubuntu/lp1761442

can you install that sosreport and retest to verify it fixes the error? If you need a test pkg for trusty or artful (or bionic) let me know and I can build in the ppa for those releases as well.

thanks, the upstream patch has been ack'ed by 2 of the maintainers and should be merged soon. It will make its way into SRU releases after that.

certainly a completely different problem from this. It doesn't happen on my amd64 system, I wonder if it's a PPC issue, or if there's some problem with your specific install. If you continue to have that problem on multiple systems you should open a new bug.

[Eric Desrochers (slashd)]

Quick update about the upstream PR from sosreport maintainer :

"fix is in the review queue, should land next week with any luck.

We're planning to make a 3.5.1 interim release shortly to help distro packagers who cannot wait until 3.6 final is out - this fix will be included in that tag."

We will start the process for Debian & Ubuntu once officially release upstream.
