Edit device #1118

rishubhjain · 2018-08-02T19:39:15Z

Getting device name from user in URL instead of request body during device edit.

Madhu-1 · 2018-08-03T05:05:02Z

@rishubhjain I have some questions related to device EDIT,
if the current device state and the requested device state doesn't match then we need to update device state

IMO if device state is already disabled we don't need to go and disable it again?

I think we are missing this check in device EDIT API can you confirm on this?

rishubhjain · 2018-08-03T05:54:20Z

@prashanthpai @aravindavk If the current state of the device is same as the requested state, then I am returning without updating etcd instead of throwing an error.

aravindavk · 2018-08-06T06:02:09Z

What is the usecase for editing device name(what is device name?)?

aravindavk · 2018-08-06T06:02:58Z

plugins/device/rest.go

 		return
 	}

+	deviceName := r.URL.Query().Get("device")


any issues while using requestBody? why query param?

Madhu-1 · 2018-08-06T06:26:39Z

why can't we return an error if device state is already set, currently if the volume is already started we are returning an error saying already started, why can't we follow the same approach here?
@rishubhjain @prashanthpai @aravindavk need your thought on this.

 	txn, err := transaction.NewTxnWithLocks(ctx, peerID)


lock peer + device before editing it, so it won't be considered for brick/volume creation during device edit.

this will be taken up after #998

lock peer+device similar to delete device

@aravindavk @prashanthpai I have changed it to device instead of device name.

 		return
 	}

Query parameters are mostly used for optional parameters. Please add device to URL itself or request body.

Use as part of url itself

+
+	if len(deviceList) > 0 {


testing with this condition is not good idea. Tests will pass if for some failure reason len(deviceList) is zero.

as this is part of smart-volume test cases, we already have devices attached to the nodes, why can't we fail the test if there are not devices in attached to peers?

+			r.Nil(err)
+		} else if device.State == "disabled" {

I would like to see below-listed tests in this PR

Disable device and check devices state is disabled

when all devices are disabled, the volume creation should fail

Enable all the devices, and check devices is enabled

when all the devices are enabled, the volume creation should pass.

do we need this check? as part of URL, I don't think we will get devices with /.

there is a possibility that user provides extra slashes /v1/devices/{peerid}//dev/vdb/, to be on the safer side we can check for a slash before adding another slash

please test this scenario, I think // will be converted into / by HTTP framework,

+func editDevice(t *testing.T) {

+	r.Nil(err)


if peerList len is zero fail the test case.

I think this should be done in the test case of peerList and not in the edit-device.

as this is dependent on the peer list, no harm in having one more higher level check
