[Qemu-devel] [PATCH v2 00/10] iotests: Fix some issues

[Max Reitz]

A couple of iotests for not-so-common formats/protocols are broken for
me, so this series fixes them.

The last patch in this series is not required, but it seemed like a good
thing to do to me.


There are more issues, but those should be fixed separately (and these
are only the ones I know of):
- 093 and 136 are flaky if the system is under load, I’ve reported this
  to Berto, and he seems to be working on it O:-)

- I’ve seen aborts in 169; Vladimir has sent patches for this, I’m just
  not sure yet who’s going to take them (the iotest patch is good, the
  QMP patch, well, is a QMP patch, so it isn’t my immediate territorry)

- 129 is broken because it uses BB throttling underneath block jobs;
  unfortunately at least the mirror job completely ignores that
  throttling (and has done so for a while), so we need to get something
  working with a filter node there.  But that’s not so easy, for a
  couple of reasons:
  (1) The commit job doesn’t work with that right now because it cannot
      deal with such a filter in the commit chain (I have to look at
      this in the context of my “Deal with filters” series)
  (2) Also, such a change results in a failed assertion:
      http://lists.nongnu.org/archive/html/qemu-block/2019-01/msg01006.html

Finally, note that tcp_chr_disconnect() has a bit of a problem with
running concurrently, so that causes tests to fail, too:
http://lists.nongnu.org/archive/html/qemu-devel/2018-12/msg05579.html


v2:
- Added a note to patch 1 that even with this patch, 237 will fail on
  Python 2.x [John]
- Put patch 5 (which fixes that) right after patch 1 [John]
- Added a note to patch 2 (which used to be patch 5) on what the exact
  issue is [John]
- Patch 6: Dropped the test for “bytes”, because you cannot use such
  objects like normal strings anyway [John?]
- Patch 9: Added

[Qemu-devel] [PATCH v2 01/10] iotests: Re-add filename filters

[Max Reitz]

A previous commit removed the default filters for qmp_log with the
intention to make them explicit; but this happened only for test 206.
There are more tests (for more exotic image formats than qcow2) which
require the filename filter, though.

Note that 237 is still broken for Python 2.x, which is fixed in the next
commit.

[Qemu-devel] [PATCH v2 02/10] iotests: Fix 237 for Python 2.x

[Max Reitz]

math.ceil() returns an integer on Python 3.x, but a float on Python 2.x.
range() always needs integers, so we need an explicit conversion on 2.x
(which does not hurt on 3.x).

It is not quite clear whether we want to support Python 2.x for any
prolonged time, but this may as well be fixed along with the other
issues some iotests have right now.

[Max Reitz]

With IMGOPTSSYNTAX, $TEST_IMG is useless for this test (it only tests
the file-posix protocol driver).  Therefore, if $TEST_IMG_FILE is set,
use that instead.

Because this test requires the file protocol, $TEST_IMG_FILE will always
be set if $IMGOPTSSYNTAX is true.

[Qemu-devel] [PATCH v2 07/10] iotests.py: Filter filename in any string value

[Max Reitz]

filter_qmp_testfiles() currently filters the filename only for specific
keys.  However, there are more keys that take filenames (such as
block-commit's @top and @base, or ssh's @path), and it does not make
sense to list them all here.  "$TEST_DIR/$PID-" should have enough
entropy not to appear anywhere randomly.

[Qemu-devel] [PATCH v2 10/10] iotests.py: s/_/-/g on keys in qmp_log()
