Well, that'd call iotests.execute_test twice and it'd perform setup
twice, too.

Usually, we want logging on for "script-style" tests, but we want
logging off for unittest-style ones. This test has opted to use both.

(Or more likely: just wanted to use run_job and just dealt with the
extramodal output.)

OK; we can turn on logging as we see fit.

Why not use:

   iotests.script_main(iotests.main, supported_fmts=['qcow2')

[Qemu-devel] [PATCH v3 4/4] iotests: use python logging for iotests.log()

2019-08-20 Thread John Snow
We can turn logging on/off globally instead of per-function.

Remove use_log from run_job, and use python logging to turn on
diffable output when we run through a script entry point.

iotest 245 changes output order due to buffering reasons.
