Hello all,
Block jobs are currently identified by the name of the block backend
of the BDS where the job was started.
This series adds a new 'id' field that is specific to the block job
and guaranteed to be unique and always present.
The patches can be summarized as follows:
- 1: Fix the prototype of stream_start(), that is going to be touched
by a later patch in the series.
- 2-5: Split BlockJob's 'id' field into 'id' and 'device' and adjust
the internal APIs to allow using the job ID.
- 6-9: Add parameters to allow setting the job ID to all QMP commands
that create block jobs (block-stream, block-commit, ...)
- 10-14: Add parameters to allow using the job ID to all QMP command
that manipulate block jobs (cancel, pause, complete, ...).
- 15: Expose the ID field in BlockJobInfo and all BLOCK_JOB_* events.
Things to do:
- Add new tests specific to job IDs.
- Add job ID support to HMP commands.
Berto
v2:
- Rebased on top of the current master
- Patch 2
- Now that job->id no longer holds the device name, replace
"The active block job for device '%s' cannot be completed"
with "The active block job '%s' cannot be completed"
in mirror_complete() and block_job_complete().
- Patch 4
- Keep using ERROR_CLASS_DEVICE_NOT_ACTIVE in find_block_job() and
change error path. [Max]
- Patch 6
- Fix merge conflicts after 274fcce.
- Patch 9
- Fix subject in commit message [Max]
- Patch 15
- Update iotests 109 and 156 [Max]
v1: https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg02438.html

'stream-start' has a parameter called 'backing-file', which is the
string to be written to bs->backing when the job finishes.
In the stream_start() implementation it is called 'backing_file_str',
but it the prototype in the header file it is called 'base_id'.
This patch fixes it so the name is the same in both cases and is
consistent with other cases (like commit_start()).

Block jobs are identified by the name of the BlockBackend of the BDS
where the job was started.
We want block jobs to have unique, arbitrary identifiers that are not
tied to a block device, so this patch decouples the ID from the device
name in the BlockJob structure.
The ID is generated automatically for the moment, in later patches
we'll allow the user to set it.

Currently the way to look for a specific block job is to iterate the
list manually using block_job_next().
Since we want to be able to identify a job primarily by its ID it
makes sense to have a function that does just that.

find_block_job() looks for a block backend with a specified name,
checks whether it has a block job and acquires its AioContext. This
patch uses block_job_next() and iterate directly over the block jobs.
In addition to that we want to identify jobs primarily by their ID, so
this patch updates find_block_job() to allow IDs too. Only one of ID
and device name can be specified when looking for a block job.

instead. In this case the ID is verified to be unique and well-formed.

allowing the user to specify the ID of the block job to be created.
The HMP 'block_stream' command remains unchanged.

This patch allows the 'block-job-set-speed' command to identify the
job by either its ID or its device name. The latter becomes now
optional since the ID alone is enough to identify the job.
The HMP 'block_job_set_speed' command remains unchanged.

To: qemu-devel
Cc: qemu-block, Max Reitz, Eric Blake, Kevin Wolf, Jeff Cody, Alberto Garcia
Now that all jobs have an ID and all QMP commands that create and
operate on block jobs can specify one we can finally expose the ID in
all BLOCK_JOB_* events and the BlockJobInfo structure.
This modifies the output of several iotests, but now we have full
control of the job IDs so this patch updates the affected ones.

Let me rephrase that: Block jobs are identified by an ID which defaults
to the name of the BlockBackend where the job was started and can't
currently be set by the user.

This approach requires us to keep track of both a device name and an ID
in order to maintain compatibility, and we always need to check both
when a job is referenced. This model is already a pain with node-name
and BB name, I wouldn't want to introduce more instances.
Why don't we go the easy route and make the ID configurable, but still
default to the device name?

This in particular feels like a step backwards. This addition is
tightening the coupling between jobs and devices instead of removing it.

These monitor related functions are the only users of the device name.
Let's simply redefine the respective QMP fields to refer to the job ID
rather than the device (because identifying the job is really what they
are used for; once we allow more than one block job per device, putting
the device there will be completely useless).
All of these redefinitions are backwards compatible. Only clients which
are new enough to set an individual ID can get something that isn't a
device name here. And they will be prepared for it.

Nice, this gets rid of another bs->job user.
But as I said in patch 2, it's better to leave out the device thing. We
can just update the documentation of the QMP commands so that 'device'
contains a job ID rather than a device name and then we can look up IDs
unconditionally. This will simplify the function even more.

That was my first approach when I started to write the series, but I
discarded it for several reasons:
- More confusing API: we'd have many instances of fields and parameters
named 'device' holding something that is not a device name or anything
similar.
We'd have e.g. block-commit(id, device), and the created job would
have a 'device' that is not the user-specified 'device' but the
user-specified 'id', which has no relation to devices.
- More risk of collisions: with the current system if no ID is specified
a new one is be generated. That's guaranteed to be valid and unique.
If we default to the device name we have no such guarantee.
- Potential compatibility break: there's a field that used to hold the
name of the device but it no longer does.
I don't think any of them is a showstopper, and as you said if a client
is recent enough to understand job IDs it should also expect the device
field to hold something different from a device name. But I'm not a big
fan of this kind of scenarios where the semantics of a returned value
depend on what we can assume that the caller is able to handle.
I thought adding a new 'ID' field was simpler. The device name is still
a device name (where it makes sense). The default ID is guaranteed to be
valid and guaranteed not to clash with user-defined IDs. The API is (in
my opinion) more clear.
The only problems that I can think of:
- BlockJobInfo and the events expose the 'device' field which is
superfluous.
- block-job-{pause,resume,...} can take an ID or a device name.
All that said, I'm open to change the implementation, but I'd like to
make sure that the problems of keeping the ID and device name merged are
considered.

Yes, the 'device' field ends up having the wrong name then. This is
ugly, but I think having code to deal with two ways of addressing jobs,
in two different namespaces, is a cost too high to be justifiable just
for making things look nicer.
I seem to remember that John is going to introduce a new set of job
management functions anyway while he generalises block jobs to just
background jobs, so in that case the ugliness would be confined to a
deprecated legacy interface. I think that's tolerable.

The expectation is that if a client passes an ID for one job, it will
pass IDs for all jobs. As long as you never pass an ID, the interface
looks exactly the same as it used to. If you pass it always, you're
obviously responsible for choosing unique IDs.
The only vaguely interesting case is if you mix both styles and then
create a new job with an explicit ID that you already used for a block
device. In this case you get an error, and I'd argue you deserve it.

Old clients never set an explicit ID, so what they get in this field is
always the default, which is a device name.
I don't see the compatibility problem?

It's really just another case of making something configurable and
letting it default to the previously hardcoded value. Pretty much a
normal thing to do.

Yes. There are two parts that I don't like about this.
The first one is that we need additional code to keep track of the
device name and to look it up.
The other, more important one is that it couples block jobs more tightly
with a BDS:
* What do you with a background job that doesn't have a device
name because it doesn't work on a BDS? Will 'device' become optional
everywhere? But how is this less problematic for compatibility than
returning non-device-name IDs? (To be clear, I don't think either is a
real problem, but you can hardly dismiss one and accept the other.)
* And what do you do once we allow more than one job per device? Then
the device name isn't suitable for addressing the job any more. And
letting the client use the device name after it started the first job,
but not any more after it started the second one, feels wrong.

Fair enough. Unless Max, Eric or someone else has something else to add

Sorry for the late response, but then again I don't actually have an
opinion either way.
The thing I feel most strongly about is the issue of storing a general
ID in a field named "device". However, as Kevin hinted at this becoming
irrelevant with John's work on decoupling block jobs from the block layer.
(And it probably will, because we don't want to call e.g.
block-job-pause that way then anymore, so John's probably going to add
newly named commands anyway, even if they do the same as the old ones. I
don't know.)
But this also means that I don't understand the first point of the
second part of what you quoted from Kevin here. I think he's referring
to what qemu returns e.g. in query-block-jobs. But why should
query-block-jobs return non-*block*-jobs? I think it should always omit
all background jobs that are not related to the block layer. Or at least
that would make sense.
The second point of the second part doesn't really strike with me
either. If a client uses the device name to identify a block job, they
should be used to a version of qemu that isn't capable of having more
than one job per device anyway, so they shouldn't launch more than a
single job per device to begin with.
So I don't think any of the pros and cons is a very strong point. I
personally feel like having a single ID field is more natural and making
the device name its default value is very intuitive, but I take issue
with its naming ("device"). So I don't care either way.
(Maybe, aside from John's work, we could get the naming issue out of the
way by introducing something like QMP aliases...?)

I actually forgot to Cc him, I'm doing it now.
The idea is that I don't want to add anything now that is going to cause
headaches later. Adding a new 'id' field to block jobs and keeping
'device' feels more natural to me, but reusing the 'device' field and
allowing any ID set by the user requires less changes both to the code
and the API.
