While working on NBD, I found myself cursing the qemu-io UI for
not letting me test various scenarios, particularly after fixing
NBD to serve at byte granularity [1].  And in the process of
writing these qemu-io enhancements, I also managed to flush out
several other bugs in the block layer proper, with fixes posted
separately, such as loss of BDRV_REQ_FUA during write_zeroes [2]

2.7 material, depends on Kevin's block-next:
git://repo.or.cz/qemu/kevin.git block-next
and on my pending "block: kill sector-based blk_write/read"
https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg00557.html

Previously posted as part of a larger NBD series [3] at v3, hence
this series starts life at v4.

[1] commit df7b97ff
[2] https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg00285.html
[3] https://lists.gnu.org/archive/html/qemu-devel/2016-04/msg03526.html

Also available as a tag at this location:
git fetch git://repo.or.cz/qemu/ericb.git nbd-qemu-io-v4

Changes since then:
More cleanups
Include readv/writev and aio_read/aio_write.
Update qemu-iotests 23 to match new 'write' semantics [kwolf]

Commit 499afa2 added --image-opts, but forgot to document it in
--help.  Likewise for commit 9e8f183 and -d/--discard.

Finally, commit 10d9d75 removed -g/--growable, but forgot to
cull it from the valid short options.

We require a C99 compiler; let's use it to express what we
really mean.

There's no reason to require the user to specify a flag just so
they can pass in unaligned numbers.  Keep 'read -p' and 'write -p'
as no-ops so that I don't have to hunt down and update all users
of qemu-io, but otherwise make their behavior default as 'read' and
'write'.  Also fix 'write -z', 'readv', 'writev', 'writev',
'aio_read', 'aio_write', and 'aio_write -z'.  For now, 'read -b',
'multiwrite', 'write -b', and 'write -c' still require alignment.

qemu-iotest 23 is updated to match, as the only test that was
previously explicitly expecting an error on an unaligned request.

We're not so close to the 80 character limit here to justify shortening
this as much. ;-)

I really wouldn't mind a full "backwards compatibility".

Would you mind removing the space after "pattern" along with this change?

Could you make that "bflag && zflag" instead?

Adding booleans was fine for the meantime between patch 2 and this one,
but I'd rather not keep it in the long run.

Testing that at most one of three booleans is set really needs addition
(the same expression using && and || is ugly and long); but you are
correct that for just two booleans, && is so much more legible.  Will fix.

Make it easier to test block drivers with BDRV_REQ_FUA in
.supported_write_flags, by adding the '-f' flag to qemu-io to
conditionally pass the flag through to specific writes ('write',
'write -z', 'writev', 'aio_write', 'aio_write -z'). You'll want
to use 'qemu-io -t none' to actually make -f useful (as
otherwise, the default writethrough mode automatically sets the
FUA bit on every write).

|| would do the same job as +, except it looks nicer.

Although technically correct, I'm very hesitant to give an R-b for
boolean arithmetics.

Holdover from rebasing the s/int/bool/ change earlier in the series.
Will fix.

Well-defined by C doesn't mean well-understood :)  I'm also more
comfortable with boolean operators for boolean variables; and I even
know of a recent patch to GNU coreutils due to gcc 7 starting to warn
about constructs on bool that look fishy because of promotion-to-int
when using non-bool operators.

When opening a file from the command line, qemu-io defaults
to BDRV_O_UNMAP but allows -d to give full control to disable
unmaps. But when opening via the 'open' command, qemu-io did
not set BDRV_O_UNMAP, and had no way to allow it.

Make it at least possible to symmetrically test things:
'qemu-io -d ignore' at the CLI now matches 'qemu-io> open'
in batch mode, and 'qemu-io' or 'qemu-io -d unmap' at
the CLI matches 'qemu-io> open -u'.

Not sure why you didn't just reuse the -d option for qemu-io itself, but:

-d=string is different than -u (as a binary flag).  But you have a
point, that being able to fully-specify ALL modes, rather than just
turning on a single mode, is more flexible. I'll see how tough it is to
fix for v5.

And it looks like supporting it in 'reopen' would also make sense.

Make it easier to control whether the BDRV_REQ_MAY_UNMAP flag
can be passed through a write_zeroes command, by adding the '-u'
flag to qemu-io 'write -z' and 'aio_write -z'.  To be useful,
the device has to be opened with 'qemu-io -d unmap' (or the
just-added 'open -u' subcommand).
