  iotests/207: Filter host fingerprint (2022-03-22 10:50:10 +0100)

----------------------------------------------------------------
Block patches for 7.0-rc1:
- iotest fixes:
  - Fix some iotests for riscv targets
  - Use GNU sed in more places where required
  - Meson-related fixes (i.e. to print errors when they occur)
  - Have qemu-img calls (from Python tests) generally raise nicely
    formattable exceptions on errors
  - Fix iotest 207
- Allow RBD images to be growable by writing zeroes past the end of
  file, fixing qcow2 on rbd

From: laokz <laokz@foxmail.com>

Some qemu-iotests(040 etc) use PCI disk to do test. Without the
mapping, RISC-V flavor use spike as default machine which has no
PCI bus, causing test failure.

From: Stefano Garzarella <sgarzare@redhat.com>

Commit d24f80234b ("block/rbd: increase dynamically the image size")
added a workaround to support growing images (eg. qcow2), resizing
the image before write operations that exceed the current size.

We recently added support for write zeroes and without the
workaround we can have problems with qcow2.

So let's move the resize into qemu_rbd_start_co() and do it when
the command is RBD_AIO_WRITE or RBD_AIO_WRITE_ZEROES.

These two spots have been missed in commit 9086c7639822 ("Rework the
checks and spots using GNU sed") - they need GNU sed, too, since they
are using the "+" address form.

From: Thomas Huth <thuth@redhat.com>

If there is a failing iotest, the output is currently not logged to
the console anymore. To get this working again, we need to run the
meson test runner with "--print-errorlogs" (and without "--verbose"
due to a current meson bug that will be fixed here:
https://github.com/mesonbuild/meson/commit/c3f145ca2b9f5.patch ).
We could update the "meson test" call in tests/Makefile.include,
but actually it's nicer and easier if we simply do not treat the
iotests as separate test target anymore and integrate them along
with the other test suites. This has the disadvantage of not getting
the detailed progress indication there anymore, but since that was
only working right in single-threaded "make -j1" mode anyway, it's
not a huge loss right now.

Quoting the TAP specification: "The plan tells how many tests will be
run [...]. It’s a check that the test file hasn’t stopped prematurely."
That's a good idea of course, so let's support that in the iotest
testrunner, too.

This adds an Exception that extends the Python stdlib
subprocess.CalledProcessError.

The difference is that the str() method of this exception also adds the
stdout/stderr logs. In effect, if this exception goes unhandled, Python
will print the output in a visually distinct wrapper to the terminal so
that it's easy to spot in a sea of traceback information.

qemu_img() returning zero ought to be the rule, not the
exception. Remove all explicit checks against the condition in
preparation for making non-zero returns an Exception.

From: John Snow <jsnow@redhat.com>

re-write qemu_img() as a function that will by default raise a
VerboseProcessException (extended from CalledProcessException) on
non-zero return codes. 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=False 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.

From: John Snow <jsnow@redhat.com>

Fortify compare_images() to be more discerning about the status codes it
receives. 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.

qemu_img_json() is a new helper built on top of qemu_img() that tries to
pull a valid JSON document out of the stdout stream.

In the event that the return code is negative (the program crashed), or
the code is greater than zero and did not produce valid JSON output, the
VerboseProcessError raised by qemu_img() is re-raised.

In the event that the return code is zero but we can't parse valid JSON,
allow the JSON deserialization error to be raised.

Add qemu_img_info() by analogy with qemu_img_measure() and
qemu_img_check(). Modify image_size() to use this function instead to
take advantage of the better diagnostic information on failure provided
(ultimately) by qemu_img().

From: John Snow <jsnow@redhat.com>

Add a qemu_img_map() function by analogy with qemu_img_measure(),
qemu_img_check(), and qemu_img_info() that all return JSON information.

Replace calls to qemu_img_pipe('map', '--output=json', ...) with this
new function, which provides better diagnostic information on failure.

Note: The output for iotest 211 changes, because logging JSON after it
was deserialized by Python behaves a little differently than logging the
raw JSON document string itself.
(iotests.log() sorts the keys for Python 3.6 support.)

Similar to other recent changes: use the qemu_img() invocation that
supports throwing loud, nasty exceptions when it fails for surprising
reasons.

(Why would "--help" ever fail? I don't know, but eliminating *all* calls
to qemu-img that do not go through qemu_img() is my goal, so
qemu_img_pipe() has to be removed.)

qemu_img_pipe() discards the return code from qemu-img in favor of
returning just its output. Some tests using this function don't save,
log, or check the output either, though, which is unsafe.

Replace all of these calls with a checked version.

Tests affected are 194, 202, 203, 234, 262, and 303.

From: John Snow <jsnow@redhat.com>

qemu_img_pipe calls blank their output when the command being run is a
'create' call and the command succeeds. 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.

From: John Snow <jsnow@redhat.com>

As part of moving all python iotest invocations of qemu-img onto a
single qemu_img() implementation, remove a few lingering uses of
qemu_img_pipe() from outside of iotests.py itself.

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.

Admittedly a mostly lateral move, but qemu_img() is essentially the
replacement for qemu_img_pipe_and_status(). It will give slightly better
diagnostics on crash.

  To: qemu-block; +Cc: Kevin Wolf, Peter Maydell, Hanna Reitz, qemu-devel

From: John Snow <jsnow@redhat.com>

qemu_img_log() calls into qemu_img_pipe(), which always removes output
for 'create' commands on success anyway. Replace all of these calls to
the simpler qemu_img_create(...) which doesn't log, but raises a
detailed exception object on failure instead.

Blank lines are removed from output files where appropriate.

From: John Snow <jsnow@redhat.com>

With the exceptional 'create' calls removed in the prior commit, change
qemu_img_log() and img_info_log() to call qemu_img() directly
instead.

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.

From: John Snow <jsnow@redhat.com>

Add a `check: bool = 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=False 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=False or with an exception handler.

Allow filters for VM.run_job(), and pass the filters given to
VM.blockdev_create() to it.

(Use this opportunity to annotate VM.run_job()'s parameter types;
unfortunately, for the filter, I could not come up with anything better
than Callable[[Any], Any] that would pass mypy's scrutiny.)

At one point, a plain string is logged, so the filters passed to it must
work fine with plain strings.  The only filters passed to it at this
point are the ones from VM.blockdev_create(), which are
filter_qmp_test_files() (by default) and 207's filter_hash().  Both
cannot handle plain strings yet, but we can make them by amending
filter_qmp() to treat them as plain values with a None key.

  To: qemu-block; +Cc: Kevin Wolf, Peter Maydell, Hanna Reitz, qemu-devel

Commit e3296cc796aeaf319f3ed4e064ec309baf5e4da4 made the ssh block
driver's error message for fingerprint mismatches more verbose, so it
now prints the actual host key fingerprint and the key type.

iotest 207 tests such errors, but was not amended to filter that
fingerprint (which is host-specific), so do it now.  Filter the key
type, too, because I guess this too can differ depending on the host
configuration.

Fixes: e3296cc796aeaf319f3ed4e064ec309baf5e4da4
       ("block: print the server key type and fingerprint on failure")
