[Qemu-devel] [PATCH 0/9] 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.

As a side note, I have many issues with iotests that are rather flaky,
I'll have to investigate those separately (093 and 136, among others).
Maybe I should just stop trying to run tests in parallel...


Max Reitz (9):
  iotests: Re-add filename filters
  iotests: Remove superfluous rm from 232
  iotests: Fix 232 for LUKS
  iotests: Fix 207 to use QMP filters for qmp_log
  iotests: Fix 237 for Python 2.x
  iotests.py: Add is_str()
  iotests.py: Filter filename in any string value
  iotests: Filter SSH paths
  iotests.py: s/_/-/g on keys in qmp_log()

[Qemu-devel] [PATCH 1/9] 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.

[Qemu-devel] [PATCH 3/9] iotests: Fix 232 for LUKS

[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 7/9] 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.

I'd really like it if we could revive Jeff's patches that made ./check
run all tests in their own subdirectory, and then where the framework
could either keep all temporary files or remove the directory, rather
than each test having to track which files it touches.

But that's a bigger task; in the meantime, this patch is fine.

I'd have shuffled this above patch 01 (or immediately below) with a note
in either commit saying that the test is still broken without both patches.

I'd also say what you're actually fixing in the commit
(range wants ints, not floats.)

Apologies, I need to be better about remembering to run the weird

This keeps biting us. Or at least, it bit me once and then it has bitten
someone else. It's not obvious that you need to accommodate this when
writing a new test.

For now, anyway, this does give us a new bandaid for a while longer.

Commit message is a bit barren, feel free to blame me for not realizing
that non-qcow2 tests used the feature I was rewriting. I may have chosen
to rewrite it differently if I had seen all the other callers. :\

Any opinions on how it shook out, now that you've had to fix things in
its wake? It felt like a lot of work to do not much to be honest, but
also it seemed like we were being too cavalier about the differences
between rich/qmp filters and text ones.

conflating bytes with strings under a function named "is_str()" makes me
nervous, but... I have no concrete objections beyond hypothetically
"What if people take this function name literally?"

There might be a more aggressive fix we can apply if we don't care about
the keys, but maybe some other filters do still care about the keys.

Ah, either way, this is obviously fine.

No, it isn't. :-)

But I think at least me running ./check -luks from time to time should
be sufficient, usually.  It's just that I had basically given up on a
clean iotests run for a month or two now...

I felt like all I wanted to say fit into the title.

Well...  I felt like it was good enough before.  These are tests, so
whatever works, works.

In theory it's nice that filters can now see the real objects, but in
practice filtering for a certain key wasn't impossible, as it was done
in this test before this patch; and in other cases, it turns out we
probably don't want to filter for a certain key at all (like when
filtering the filename).

So all in all I'd have to say to me it mostly makes things more
complicated than necessary.  But OTOH I wouldn't say it's
overcomplicated because I can see the theoretical purpose, at least.  It
makes sense to give objects to the filters -- but it doesn't seem too
useful in the end.

Also, when in doubt, it's probably better to really work on objects
instead of having just simple text filters.  After all, at least I write
Python tests to get away from those text filters we have in the bash tests.

Hm.  Well, the strings from 2.x are byte strings in 3.x, so.

But then there's this:

$ python2
[...]
>>> 'foo'.replace('f', 'g')
'goo'
>>> u'foo'.replace('f', 'g')
u'goo'

$ python3
[...]
>>> 'foo'.replace('f', 'g')
'goo'
>>> b'foo'.replace('f', 'g')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: a bytes-like object is required, not 'str'

So that just doesn't work for the next patch.  How about I just drop the
bytes test and if at some point someone feels the need to add it, we can
think about it again?
