v1: http://www.redhat.com/archives/libvir-list/2016-September/msg01090.html
Differences since v1:
Patches 1-5 are new...
Patch 1 is essentially the former patch 8.5 added after initial review
based on a review comment. Erik Skultety and I went back and forth
on this one a few times and this is the result
Patch 2 is a result of being frustrated by a generic error message when
I know we could return whatever qemu gives us
Patch 3 is simple code motion - the conf_disk is closer to usage now
Patch 4 & 5 create and use the same algorithm to set the default values
that weren't provided.
Patches 6-7 have already been ACK'd... I've been waiting to push because
they will interfere with libvirt-perl builds and since the 2.3.0 hasn't
been published yet, I'm still holding onto them.
Patch 8 is the former patch 8, but reworked mostly in qemu_driver.c, but
also a change in qemu_monitor_json.c to use "P:" instead of "U:"
for
then length values. For _length a 0 is an invalid value, so we'll use
it to mean "nothing changed"
Patch 9 is the former patch 11 and is mostly intact, with major difference
being the removal of the CHECK_IOTUNE_MAX_LENGTH macro (it was causing
domain disappearance)
Patch 10 is the former patch 12 and is unchanged. It also has been ACKd
Patch 11-12 are new - it's the virsh code.
John Ferlan (12):
qemu: Create a macro to handle setting bytes/iops iotune values
qemu: Return real error message for block_set_io_throttle
qemu: Move setting of conf_disk in qemuDomainSetBlockIoTune
qemu: Introduce qemuDomainSetBlockIoTuneSetDefaults
qemu: Use qemuDomainsetBlockIoTuneSetDefaults for config
include: Add new definitions for duration for bps/iops throttling
caps: Add new capability for the bps/iops throttling length
qemu: Add length for bps/iops throttling parameters to driver
conf: Add support for blkiotune "_length" options
qemu: Add the length options to the iotune command line
virsh: Create a macro to add IOTUNE values
virsh: Add _length parameters to virsh output

New subject: [libvirt] [PATCH v2 01/12] qemu: Create a macro to handle setting bytes/iops iotune values
Create a macros to hide all the comparisons for each of the fields.
Add a 'continue;' for a compiler hint that we only need to find one
this should be similar enough to the if - elseif - elseif logic.

Could this be a macro instead? 5 booleans, it just seems a tiny bit odd.

And then you'll end up just with snippet like ^^this. Or you could use
bitwise OR'd flags instead of the booleans, as it scales better (in terms of
number of arguments), though I'm not very fond of that even though it works.
ACK with the adjustment, but see 5/12 as well before pushing.

Could this be a macro instead? 5 booleans, it just seems a tiny bit odd.
Probably - I can try... Obvious impact later when _length is added.

And then you'll end up just with snippet like ^^this. Or you could use
bitwise OR'd flags instead of the booleans, as it scales better (in terms of
number of arguments), though I'm not very fond of that even though it works.
ACK with the adjustment, but see 5/12 as well before pushing.
There is no official bug report - it was one of those visual inspection
and oh sh*t moments during testing when I didn't release my domain
wasn't started and my max settings were zero'd out.
I can merge the two together as well - not a problem.

New subject: [libvirt] [PATCH v2 05/12] qemu: Use qemuDomainsetBlockIoTuneSetDefaults for config
Rather than repeat the lines in the persistent def, use the same helper
to set config values.
This also fixes a bug where config values for *_max and size_iops_sec would
be set back to 0 if a config value was set.

Is there a BZ for this^^, if yes, then please add it here, if not, then
I think this can be easily squashed to 4/12.

this patch caused a rebase conflict but you'd come across that for sure.
ACK (when I read the cover letter it was already too late as at that time I'd
already sent an ACK to 6/12, so I'll do it here as well to stay consistent)

Hmm. You can disregard my comment in 4/12 about replacing the whole function
with a macro, instead I suggest keeping the function and making the macro below
also work for all the settings above, otherwise it just doesn't look right, one
part of the function being expanded while the other covered by a macro because
the behaviour is slightly different (I have to admit though, it was kinda
painful to comprehend what's going on on the qemu side)

Basically I have nothing against this^^, just a note that should the
capabilities covering iotune be extended in the future I can image this to be
handled as OR'd flags rather than individual variables, but it's okay now.
ACK with the macro adjustment above.

Yes, quite painful - especially when I realized it after the initial
series... The difference is I went with a function.
I create a macro for the setting of the defaults

Basically I have nothing against this^^, just a note that should the
capabilities covering iotune be extended in the future I can image this to be
handled as OR'd flags rather than individual variables, but it's okay now.
Ironically - there is another field, but it was added before the -length
values were supported. That's the *next* series I'll be posting...
The tricky part of the OR'd flags will be how the command line logic is
put together. It's a rather unique hack that ultimately is in
qemuMonitorJSONSetBlockIoThrottle regarding how the command line is put
together with a bit of "knowledge" regarding "when" the boolean was
added.
Coming to the theater of the absurd soon is "max" (added in qemu 1.7),
"group" (added in qemu 2.4), and "max_length" (added in qemu 2.6).
Tks -
John
ACK with the macro adjustment above.

Again a nitpick, I guess the -length setting should not get scaled when one
tries e.g. 'kib' to pass along with the setting. In terms of a cleanup, yes,
it's very welcome, so maybe add a 'SCALE' argument - your call.

Again a nitpick, I guess the -length setting should not get scaled when one
Upon closer inspect, good catch and it's not just -length... The iops
values aren't scaled either!
There's now two macros... I renamed the current one to add a _SCALED and
created a new one that uses vshCommandOptULongLong (I don't want to mess
with another SCALE argument)
tries e.g. 'kib' to pass along with the setting. In terms of
a cleanup, yes,
it's very welcome, so maybe add a 'SCALE' argument - your call.
and the -length values will all be part of the non scaled version..
Thanks for the review - the series is now pushed.

Differences since v1:
Patches 1-5 are new...
Patch 1 is essentially the former patch 8.5 added after initial review
based on a review comment. Erik Skultety and I went back and forth
on this one a few times and this is the result
Patch 2 is a result of being frustrated by a generic error message when
I know we could return whatever qemu gives us
Patch 3 is simple code motion - the conf_disk is closer to usage now
Patch 4 & 5 create and use the same algorithm to set the default values
that weren't provided.
Patches 6-7 have already been ACK'd... I've been waiting to push because
they will interfere with libvirt-perl builds and since the 2.3.0 hasn't
been published yet, I'm still holding onto them.
Patch 8 is the former patch 8, but reworked mostly in qemu_driver.c, but
also a change in qemu_monitor_json.c to use "P:" instead of "U:"
for
then length values. For _length a 0 is an invalid value, so we'll use
it to mean "nothing changed"
Patch 9 is the former patch 11 and is mostly intact, with major difference
being the removal of the CHECK_IOTUNE_MAX_LENGTH macro (it was causing
domain disappearance)
Patch 10 is the former patch 12 and is unchanged. It also has been ACKd
Patch 11-12 are new - it's the virsh code.
John Ferlan (12):
qemu: Create a macro to handle setting bytes/iops iotune values
qemu: Return real error message for block_set_io_throttle
qemu: Move setting of conf_disk in qemuDomainSetBlockIoTune

based on a review comment. Erik Skultety and I went back and forth
on this one a few times and this is the result
Patch 2 is a result of being frustrated by a generic error message when
I know we could return whatever qemu gives us
Patch 3 is simple code motion - the conf_disk is closer to usage now
Patch 4 & 5 create and use the same algorithm to set the default values
that weren't provided.
Patches 6-7 have already been ACK'd... I've been waiting to push because
they will interfere with libvirt-perl builds and since the 2.3.0 hasn't
been published yet, I'm still holding onto them.
Patch 8 is the former patch 8, but reworked mostly in qemu_driver.c, but
also a change in qemu_monitor_json.c to use "P:" instead of "U:"
for
then length values. For _length a 0 is an invalid value, so we'll use
it to mean "nothing changed"
Patch 9 is the former patch 11 and is mostly intact, with major difference
being the removal of the CHECK_IOTUNE_MAX_LENGTH macro (it was causing
domain disappearance)
Patch 10 is the former patch 12 and is unchanged. It also has been ACKd
Patch 11-12 are new - it's the virsh code.
