[dpdk-dev] [PATCH v2] usertools: dpdk-telemetry-client.py run into looping status

[Andrius Sirvys]

The ast.literal_eval() was used incorrectly and wouldn't properly
retrieve the user option. Was causing the options to keep being listed
in a loop. Removed and replaced with raw_input() being cast to an int.
Works as expected now.

You mean you added "ast.literal_eval()" without testing it?

Kevin, that's not the first time I ask,
who is testing this telemetry stuff?
I have the bad feeling this is a toy,
and you send random untested patches for it.
How I can know this patch is seriously tested enough
before merging it at the last minute in 19.08?

Why changing this indentation?

[dpdk-dev] [PATCH v3] usertools: fix input handling in telemetry script

[Andrius Sirvys]

This commit removes the unnecesarry ast.literal_eval() function call
from the input handling, which now relies just on raw_input() to get
its input.

v3: Reduced scope of changes only to required Python 2 fix

Please note that the dpdk-telemetry-client.py script has a number of
issues with Python3 support. Fixing Python3 support is being deferred
to DPDK 19.11 release.

Thanks for the patch re-spin Andrius. This is the smallest change possible
to fix the current issue, and I recommend including in 19.08 release.

Agree the Python3 support requires larger refactoring, which should be
undertaken for 19.11.

OK, hope it will be good enough for 19.08.
Applied, thanks
