Hi,
Since some time we are trying to move our neutron-functional job to be run with python 3 - see patch [1].
Unfortunately we are still hitting same issue, some subunit parser error with message like "Parser Error: {{{Short read - got 4090 bytes, wanted 4376 bytes}}}”. See for example here: [2].
That cause that only around half of tests are executed and our job is failed.
We found similar bug in Cinder [3] and we were trying to limit number of output produced by tests but this doesn’t help much.
I don’t know how to move forward with this issue. Maybe someone more familiar with ostestr/subunit can take a look at it and help us to make this job finally working :)
