Hiya!
This series effectively replaces qemu_img_pipe_and_status() with a
rewritten function named qemu_img() that raises an exception on non-zero
return code by default. By the end of the series, every last invocation
of the qemu-img binary ultimately goes through qemu_img().
The exception that this function raises includes stdout/stderr output
when the traceback is printed in a a little decorated text box so that
it stands out from the jargony Python traceback readout.
(You can test what this looks like for yourself, or at least you could,
by disabling ztsd support and then running qcow2 iotest 065.)
Negative tests are still possible in two ways:
- Passing check=False to qemu_img, qemu_img_log, or img_info_log
- Catching and handling the CalledProcessError exception at the callsite.
Thanks! Applied to my block branch:
