[Qemu-devel] [PATCH v5 0/3] Fix qemu-io return value on failure

[Nir Soffer]

This series fix qemu-io to fail with non zero exit code when failing to open
the file.

Changes since v4:
- Added _unsupported_fmt helper
- Test any format except raw, instead of only raw
- Don't test stderr content, depends on the format
- New test move to 174 since 173 is pending
- Private copyright for new test
- Fix commit message issues

Changes since v3:
- Add cover letter
- Squash the tests fix with the behavior change, so git bisect landing on the
  change in behavior does not hit unnecessarily-broken tests.

Tested by running qemu-io manually and by running tests/check-block.sh.
Note that test 059 has one unrelated test failure.

Nir Soffer (3):
  qemu-io: Return non-zero exit code on failure
  qemu-iotests: Add _unsupported_fmt helper
  qemu-io: Add failure regression tests

[Qemu-devel] [PATCH v5 1/3] qemu-io: Return non-zero exit code on failure

[Nir Soffer]

The result of openfile was not checked, leading to failure deep in the
actual command with confusing error message, and exiting with exit code 0.

Here is a simple example - trying to read with the wrong format:

    $ touch file
    $ qemu-io -f qcow2 -c 'read -P 1 0 1024' file; echo $?
    can't open device file: Image is not in qcow2 format
    no file open, try 'help open'
    0

With this patch, we fail earlier with exit code 1:

    $ ./qemu-io -f qcow2 -c 'read -P 1 0 1024' file; echo $?
    can't open device file: Image is not in qcow2 format
    1

Failing earlier, we don't log this error now:

    no file open, try 'help open'

But some tests expected it; the line was removed from the test output.
