[ovirt-devel] Jenkins help

[Germano Veit Michel]

Hi,

I'm struggling with a check-patch failing. This is the error (I think):

[7;33m* Module vdsm.tool.update_volume [0m
[1;31mE [0m: 87,16: [1;31mInstance of '_Client' has no 'Host' member [0m (
[1;31mno-member [0m)
[1;31mE [0m:101,23: [1;31mInstance of '_Client' has no 'StoragePool' member
[0m ( [1;31mno-member [0m)

The way I understand it, the error above from [1] means that the check
patch fails because the cli object does not contain Host or StoragePool.
However, from reading the code it seems the Host and StoragePool members
are created at runtime by parsing the API schema. So static checking for
[2] and [3] fails.

I see some other tools doing similar things (i,e. dump_volume_chains), but
I can't find anything specific done to prevent it. Or am I missing
something?

Any idea on how to solve this?

[ovirt-devel] Re: Dealing with TaskID in vdsm api

[Germano Veit Michel]

Hi Marcin,

Yes, I know that. Let me try to be clearer.

1. My API command passes a JobID as argument.
2. VDSM creates a taskID for it once it starts running the command
3. I want to retrieve or define the taskID somehow.

The current API does show the TaskIDs and JobIDs. The JobID I know, but I
want to know the TaskID for the API command I submitted.

And the API does not have enough info to correlate the JobID with the
TaskID. See:

# vdsm-client Host getJobs
{
"8a4a6452-bb9c-11e8-8871-52540016c103": {
"status": "done",
"job_type": "storage",
"id": "8a4a6452-bb9c-11e8-8871-52540016c103",
"description": "update_volume"
},

# vdsm-client Host getAllTasks
{
"eb3f55af-c004-44af-8b28-87f8924a7623": {
"verb": "sdm_update_volume",
"code": 0,
"state": "finished",
"tag": "sdm",
"result": "",
"message": "1 jobs completed successfully",
"id": "eb3f55af-c004-44af-8b28-87f8924a7623"
},

I want to somehow retrieve or define the taskID
(eb3f55af-c004-44af-8b28-87f8924a7623) after using the following
update_volume command:

~~~
from vdsm import client
cli = client.connect('localhost', 54321, use_tls=True)
cli.SDM.update_volume(job_id=job, vol_info=vol, vol_attr=changes)
~~~

[ovirt-devel] Re: Dealing with TaskID in vdsm api

[Marcin Sobczyk]

From what I can see in: 
https://github.com/oVirt/vdsm/blob/0725f32994293514d3275528c44687e8e800d6a6/lib/vdsm/storage/hsm.py#L3586

you should try and query sdm jobs by using Host.getJobs API call.

Hi Marcin,

Thanks for replying. In short, this is what I am doing:

~~~
from vdsm import client
cli = client.connect('localhost', 54321, use_tls=True)
cli.SDM.update_volume(job_id=job, vol_info=vol, vol_attr=changes)
~~~

This last line does an API call. A taskID is generated in vdsm, I can 
only specify the JobID as a parameter of the call. From what I read, 
the taskID should be sent on the HTTP header if I want to set it. But 
I cannot find how to do it.
The whole point is that I want to know the taskID, so I can monitor 
the task and clear it after it is finished.


So:
* How do I retrieve the taskID vdsm generated for this?
or
* How to I query VDSM to give me the taskID for the JobID I passed as 
argument

or
* How can I specify the taskID to be used given I'm using vdsm client 
(from vdsm import client).

or
* any other idea you have on how to handle this?

Am I missing something or there is some missing implementation for 
doing this?


Thanks

Hi all,

The patch to fix this has been committed via [1]. Basically the new code forces 
the obtain method to be the one with no parameters specified. In addition, if 
no obtain method found, do throw NoSuchMethodException error.

@Ondra, could you please help me to review it? Great thanks.

Hi Patrick, Ondra,

This issue could be reproduced in my local dev environment. After digging into 
the Java SDK, the issue probably is caused by getting the wrong method to 
invoke.

Although the `DiskService.GetResponse` defined in API model has only a single 
@Out (getter) method `Disk disk()`, the Java SDK generator adds a additional 
setter method `void disk(Disk disk)` in `DiskService.GetResponse` class. The 
code here [1] use `getResponse.getClass().getDeclaredMethods()[0]` to fetch the 
method for getting the Disk, while it actually get the method `void disk(Disk 
disk)`, which obviously produces the `wrong number of arguments` error.

This issue also affect fetching list of objects via `connection.link()`. I 
could get this fixed and commit a PR in gerrit soon.

Please correct me if I'm wrong or missing anything. Thanks.
