* iotests: define group in each iotestVladimir Sementsov-Ogievskiy2021-01-201-0/+1
| | | | | | | | | | | | | | | | | | | | | We are going to drop group file. Define group in tests as a preparatory step. The patch is generated by cd tests/qemu-iotests grep '^[0-9]\{3\} ' group | while read line; do file=$(awk '{print $1}' <<< "$line"); groups=$(sed -e 's/^... //' <<< "$line"); awk "NR==2{print \"# group: $groups\"}1" $file > tmp; cat tmp > $file; done Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-Id: <20210116134424.82867-7-vsementsov@virtuozzo.com> Signed-off-by: Eric Blake <eblake@redhat.com>

* iotests: Remove Python 2 compatibility codeKevin Wolf2019-10-041-3/+0Star
| | | | | | | | | | | | | | | Some scripts check the Python version number and have two code paths to accomodate both Python 2 and 3. Remove the code specific to Python 2 and assert the minimum version of 3.6 instead (check skips Python tests in this case, so the assertion would only ever trigger if a Python script is executed manually).

* iotests: Restrict file Python tests to fileMax Reitz2019-09-101-1/+2
| | | | | | | | | | | | Most of our Python unittest-style tests only support the file protocol. You can run them with any other protocol, but the test will simply ignore your choice and use file anyway. We should let them signal that they require the file protocol so they are skipped when you want to test some other protocol.

* iotests: Different iterator behavior in Python 3Max Reitz2018-10-311-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Python 3, several functions now return iterators instead of lists. This includes range(), items(), map(), and filter(). This means that if we really want a list, we have to wrap those instances with list(). But then again, the two instances where this is the case for map() and filter(), there are shorter expressions which work without either function. On the other hand, sometimes we do just want an iterator, in which case we have sometimes used xrange() and iteritems() which no longer exist in Python 3. Just change these calls to be range() and items(), works in both Python 2 and 3, and is really what we want in 3 (which is what matters). But because it is so simple to do (and to find and remove once we completely switch to Python 3), make range() be an alias for xrange() in the two affected tests (044 and 163). In one instance, we only wanted the first instance of the result of a filter() call. Instead of using next(filter()) which would work only in Python 3, or list(filter())[0] which would work everywhere but is a bit weird, this instance is changed to use a generator expression with a next() wrapped around, which works both in 2.7 and 3.

* iotests: Use // for Python integer divisionMax Reitz2018-10-311-1/+1
| | | | | | | | | | | | In Python 3, / is always a floating-point division. We usually do not want this, and as Python 2.7 understands // as well, change all integer divisions to use that.

* iotests: Use Python byte strings where appropriateMax Reitz2018-10-311-4/+4
| | | | | | | | | | | | | | | | | | | | | Since byte strings are no longer the default in Python 3, we have to explicitly use them where we need to, which is mostly when working with structures. It also means that we need to open a file in binary mode when we want to use structures. On the other hand, we have to accomodate for the fact that some functions (still) work with byte strings but we want to use unicode strings (in Python 3 at least, and it does not matter in Python 2). This includes base64 encoding, but it is most notable when working with the subprocess module: Either we set universal_newlines to True so that the default streams are opened in text mode (hence this parameter is aliased as "text" as of 3.7), or, if that is not possible, we have to decode the output to a normal string.

* qemu-iotests: qcow2: Test growing large refcount tableKevin Wolf2012-11-141-0/+117
Actually writing all the content with 512 byte sector size would take forever, therefore build the image file with a Python script and use qemu-io for the last write that actually triggers the refcount table growth. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
