This will produce a stack trace that will show the command line arguments and return code from the failed process run. Users that want something more flexible (there appears to be only one) can use check=3DFalse and manage the return themselves. However, when the return code is negative, the Exception will be raised no matter what. This is done under the belief that there's no legitimate reason, even in negative tests, to see a crash from qemu-img.

If qemu_img() returns an exit code that implies it didn't actually perform the comparison, treat that as an exceptional circumstance and force the caller to be aware of the peril. If a negative test is desired (perhaps to test how qemu_img compare behaves on malformed images, for instance), it is still possible to catch the exception in the test and deal with that circumstance manually.

Thus, the normative output for this command in iotest 149 is to print a blank line. We can remove the logging from this invocation and use a checked invocation, but we still need to inspect the actual output to see if we want to retroactively skip the test due to missing cipher support.

Several cases here rely on the knowledge that qemu_img_pipe() suppresses *all* output on a successful case when the command being issued is 'create'. 065: This call's output is inspected, but it appears as if it's expected to succeed. Replace this call with the checked qemu_img() variant instead to get better diagnostics if/when qemu-img itself fails. 237: "create" call output isn't actually logged. Use qemu_img_create() instead, which checks the return code. Remove the empty lines from the test output. 296: Two calls; -create: Expected to succeed. Like other create calls, the output isn't actually logged. Switch to a checked variant (qemu_img_create) instead. The output for this test is a mixture of both test styles, so actually replace the blank line for readability. -amend: This is expected to fail. Log the output. After this patch, the only uses of qemu_img_pipe are internal to iotests.py and will be removed in subsequent patches.

For now, allow these calls to qemu-img to return non-zero on the basis that any unusual output will be logged anyway. The very next commit begins to enforce a successful exit code by default even for the logged functions.

charset="utf-8" Add a `check: bool =3D True` parameter to both functions and make their qemu_img() invocations raise on error by default. users of img_info_log: 206, 207, 210, 211, 212, 213, 237, 242, 266, 274, 302 users of qemu_img_log: 044, 209, 274, 302, 304 iotests 242 and 266 need to use check=3DFalse for their negative tests. iotests 206, 210, 211, 212, 213, 237, 274 and 302 continue working normally. As of this commit, all calls to QEMU_IMG made from iotests enforce a return code of zero by default unless explicitly disabled or suppressed by passing check=3DFalse or with an exception handler.
