We have multiple clients of qemu_strtosz (qemu-io, the opts visitor,
the keyval visitor), and it gets annoying that edge-case testing is
impacted by implicit rounding to 53 bits of precision due to parsing
with strtod(). As an example posted by Rich Jones:
$ nbdkit memory $(( 2**63 - 2**30 )) --run \
'build/qemu-io -f raw "$uri" -c "w -P 3 $(( 2**63 - 2**30 - 512 )) 512" '
write failed: Input/output error
because 9223372035781033472 got rounded to 0x7fffffffc0000000 which is
out of bounds.
It is also worth noting that our existing parser, by virtue of using
strtod(), accepts decimal AND hex numbers, even though test-cutils
previously lacked any coverage of the latter until the previous patch.
We do have existing clients that expect a hex parse to work (for
example, iotest 33 using qemu-io -c "write -P 0xa 0x200 0x400"), but
strtod() parses "08" as 8 rather than as an invalid octal number, so
we know there are no clients that depend on octal. Our use of
strtod() also means that "0x1.8k" would actually parse as 1536 (the
fraction is 8/16), rather than 1843 (if the fraction were 8/10); but
as this was not covered in the testsuite, I have no qualms forbidding
hex fractions as invalid, so this patch declares that the use of
fractions is only supported with decimal input, and enhances the
testsuite to document that.
Our previous use of strtod() meant that -1 parsed as a negative; now
that we parse with strtoull(), negative values can wrap around modulo
2^64, so we have to explicitly check whether the user passed in a '-';
and make it consistent to also reject '-0'. This has the minor effect
of treating negative values as EINVAL (with no change to endptr)
rather than ERANGE (with endptr advanced to what was parsed), visible
in the updated iotest output.
We also had no testsuite coverage of "1.1e0k", which happened to parse
under strtod() but is unlikely to occur in practice; as long as we are
making things more robust, it is easy enough to reject the use of
exponents in a strtod parse.
The fix is done by breaking the parse into an integer prefix (no loss
in precision), rejecting negative values (since we can no longer rely
on strtod() to do that), determining if a decimal or hexadecimal parse
was intended (with the new restriction that a fractional hex parse is
not allowed), and where appropriate, using a floating point fractional
parse (where we also scan to reject use of exponents in the fraction).
The bulk of the patch is then updates to the testsuite to match our
new precision, as well as adding new cases we reject (whether they
were rejected or inadvertently accepted before).

When querying image extents for raw image, qemu-nbd reports holes as
zero:
$ qemu-nbd -t -r -f raw empty-6g.raw
$ qemu-img map --output json nbd://localhost
[{ "start": 0, "length": 6442450944, "depth": 0, "zero": true, "data": true, "offset": 0}]
$ qemu-img map --output json empty-6g.raw
[{ "start": 0, "length": 6442450944, "depth": 0, "zero": true, "data": false, "offset": 0}]
Turns out that qemu-img map reports a hole based on BDRV_BLOCK_DATA, but
nbd server reports a hole based on BDRV_BLOCK_ALLOCATED.
The NBD protocol says:
NBD_STATE_HOLE (bit 0): if set, the block represents a hole (and
future writes to that area may cause fragmentation or encounter an
NBD_ENOSPC error); if clear, the block is allocated or the server
could not otherwise determine its status.
qemu-img manual says:
whether the sectors contain actual data or not (boolean field data;
if false, the sectors are either unallocated or stored as
optimized all-zero clusters);
To me, data=false looks compatible with NBD_STATE_HOLE. From user point
of view, getting same results from qemu-nbd and qemu-img is more
important than being more correct about allocation status.
Changing nbd server to report holes using BDRV_BLOCK_DATA makes qemu-nbd
results compatible with qemu-img map:
$ qemu-img map --output json nbd://localhost
[{ "start": 0, "length": 6442450944, "depth": 0, "zero": true, "data": false, "offset": 0}]

Some error messages contain ambiguous representations of the 'node-name'
parameter. This can be particularly confusing when exchanging QMP
messages (C = client, S = server):
C: {"execute": "block_resize", "arguments": { "device": "my_file", "size": 26843545600 }}
S: {"error": {"class": "GenericError", "desc": "Cannot find device=my_file nor node_name="}}
^^^^^^^^^
This error message suggests one could send a message with a key called
'node_name':
C: {"execute": "block_resize", "arguments": { "node_name": "my_file", "size": 26843545600 }}
^^^^^^^^^
but using the underscore is actually incorrect, the parameter should be
'node-name':
S: {"error": {"class": "GenericError", "desc": "Parameter 'node_name' is unexpected"}}
This behavior was uncovered in bz1651437, but I ended up going down a
rabbit hole looking for other areas where this miscommunication might
occur and changing those accordingly as well.

Without any of HEAD^ or HEAD^^ applied, qemu will most likely crash on
the qemu-io invocation, for a variety of immediate reasons. The
underlying problem is generally a use-after-free access into
backup-top's BlockCopyState.
With only HEAD^ applied, qemu-io will run into an EIO (which is not
capture by the output, but you can see that the qemu-io invocation will
be accepted (i.e., qemu-io will run) in contrast to the reference
output, where the node name cannot be found), and qemu will then crash
in query-named-block-nodes: bdrv_get_allocated_file_size() detects
backup-top to be a filter and passes the request through to its child.
However, after bdrv_backup_top_drop(), that child is NULL, so the
recursive call crashes.
With HEAD^^ applied, this test should pass.

To disallow certain refcount_bits values, some _unsupported_imgopts
invocations look like "refcount_bits=1[^0-9]", i.e. they match an
integer boundary with [^0-9]. This expression does not match the end of
the string, though, so it breaks down when refcount_bits is the last
option (which it tends to be after the rewrite of the check script in
Python).
Those invocations could use \b or \> instead, but those are not
portable. They could use something like \([^0-9]\|$\), but that would
be cumbersome. To make it simple and keep the existing invocations
working, just let _unsupported_imgopts match the regex against $IMGOPTS
plus a trailing space.

When using the _launch_qemu and _send_qemu_cmd functions from
common.qemu, any QMP events get mixed in with the output from
the commands and responses.
This makes it difficult to write a test case as the ordering
of events in the output is not stable.
This introduces a variable 'capture_events' which can be set
to a list of event names. Any events listed in this variable
will not be printed, instead collected in the $QEMU_EVENTS
environment variable.
A new '_wait_event' function can be invoked to collect events
at a fixed point in time. The function will first pull events
cached in $QEMU_EVENTS variable, and if none are found, will
then read more from QMP.

there will be more error scenarios for some of these methods, which
will benefit from fine grained error message reporting. So it is

Just use classes introduced in previous three commits. Behavior
difference is described in these three commits.
Drop group file, as it becomes unused.
Drop common.env: now check is in python, and for tests we use same
python interpreter that runs the check itself. Use build environment
PYTHON in check-block instead, to keep "make check" use the same
python.
Checking for virtio-blk moved to iotests.py, as it actually iotests.py
dependency. Actually not all python iotests depend on it, so in future
it may be refactored to checked only when really needed.

Add TestRunner class, which will run tests in a new python iotests
running framework.
There are some differences with current ./check behavior, most
significant are:
- Consider all tests self-executable, just run them, don't run python
by hand.
- Elapsed time is cached in json file
- Elapsed time precision increased a bit
- Instead of using "diff -w" which ignores all whitespace differences,
manually strip whitespace at line end then use python difflib, which
no longer ignores spacing mid-line

Add python script with new logic of searching for tests:
Current ./check behavior:
- tests are named [0-9][0-9][0-9]
- tests must be registered in group file (even if test doesn't belong
to any group, like 142)
Behavior of findtests.py:
- group file is dropped
- tests are all files in tests/ subdirectory (except for .out files),
so it's not needed more to "register the test", just create it with
appropriate name in tests/ subdirectory. Old names like
[0-9][0-9][0-9] (in root iotests directory) are supported too, but
not recommended for new tests
- groups are parsed from '# group: ' line inside test files
- optional file group.local may be used to define some additional
groups for downstreams
- 'disabled' group is used to temporary disable tests. So instead of
commenting tests in old 'group' file you now can add them to
disabled group with help of 'group.local' file
- selecting test ranges like 5-15 are not supported more
(to support restarting failed ./check command from the middle of the
process, new argument is added: --start-from)
Benefits:
- no rebase conflicts in group file on patch porting from branch to
branch
- no conflicts in upstream, when different series want to occupy same
test number
- meaningful names for test files
For example, with digital number, when some person wants to add some
test about block-stream, he most probably will just create a new
test. But if there would be test-block-stream test already, he will
at first look at it and may be just add a test-case into it.
And anyway meaningful names are better.
This commit doesn't update check behavior (which will be done in
further commit), still, the documentation changed like new behavior is
already here. Let's live with this small inconsistency for the
following few commits, until final change.

ccd3b3b811 has deprecated short-hand boolean options (i.e., options
with values). All options without values are interpreted as boolean
options, so this includes the invalid option "snapshot.foo" used in
iotest 178.
So after ccd3b3b811, 178 fails with:
+qemu-img: warning: short-form boolean option 'snapshot.foo' deprecated
+Please use snapshot.foo=on instead
Suppress that deprecation warning by passing some value to it (it does
not matter which, because the option is invalid anyway).

Iotest 257 dumps a lot of in-progress information of backup job, such
as offset and bitmap dirtiness. Further commit will move backup to be
one block-copy call, which will introduce async parallel requests
instead of plain cluster-by-cluster copying. To keep things
deterministic, allow only one worker (only one copy request at a time)
for this test.

The further change of moving backup to be a one block-copy call will
make copying chunk-size and cluster-size two separate things. So, even
with 64k cluster sized qcow2 image, default chunk would be 1M.
Test 219 depends on specified chunk-size. Update it for explicit
chunk-size for backup as for mirror.

The further change of moving backup to be a one block-copy call will
make copying chunk-size and cluster-size two separate things. So, even
with 64k cluster sized qcow2 image, default chunk would be 1M.
185 test however assumes, that with speed limited to 64K, one iteration
would result in offset=64K. It will change, as first iteration would
result in offset=1M independently of speed.
So, let's explicitly specify, what test wants: set max-chunk to 64K, so
that one iteration is 64K. Note, that we don't need to limit
max-workers, as block-copy rate limiter will handle the situation and
wouldn't start new workers when speed limit is obviously reached.

After introducing parallel async copy requests instead of plain

as we need to wait for several parallel request. So, let's gently wait

If main job coroutine called job_yield (while some background process
is in progress), we should give it a chance to call job_pause_point().
It will be used in backup, when moved on async block-copy.
Note, that job_user_pause is not enough: we want to handle
child_job_drained_begin() as well, which call job_pause().
Still, if job is already in job_do_yield() in job_pause_point() we
should not enter it.
iotest 109 output is modified: on stop we do bdrv_drain_all() which now
triggers job pause immediately (and pause after ready is standby).
