[LinfyZhai]

Build: \\redmond\wsscfs\OSTCData\Builds\omi\develop\1.4.0-37 \\redmond\wsscfs\OSTCData\Builds\omiscriptprovider\develop\1.1.1-35 Reproduce steps:

1. Write mof file:

   class test1
   {
       [key] uint64 v_Key;
       Real32 testR32;
   };

2. Generate above test1.mof with below command: root@omi64-ubun16-01:/opt/omi/lib# /opt/omi/bin/omigen_py /opt/omi/lib/test1/schema.mof test1 -d /opt/omi/lib/test1/ And add code like following in mi_main.py:

   def test1_EnumerateInstances (
   context, nameSpace, className, propertySet, keysOnly):
   instance = context.NewInstance ('test1')
   instance.SetValue ('v_Key', MI_Uint32(1))
   instance.SetValue ('testR32', MI_Real32(0))
   context.PostInstance (instance)
   context.PostResult (MI_RESULT_OK)

3. Register your provider and run ei.

   
   root@omi64-ubun16-01:/opt/omi/lib# /opt/omi/bin/omireg --Python test1
   Created /etc/opt/omi/conf/omiregister/root-cimv2/test1.reg

This is an exist bug from the beginning, we just find it today.

I have tried instance.SetValue('testR32',MI_Real32(0.0)), it also get the error.

[c64cosmin]

Fails even when a variable is passed as zero.

@c64cosmin , do you mean a = 0 in the code? I tried this works fine.

This issue should be fixed with the above patch:

$ omicli ei root/cimv2 test1
instance of test1
{
    [Key] v_Key=1
    testR32=0
}

Code:

def test1_EnumerateInstances (
    context, nameSpace, className, propertySet, keysOnly):
    instance = context.NewInstance ('test1')
    instance.SetValue ('v_Key', MI_Uint32(1))
    instance.SetValue ('testR32', MI_Real32(float(0)))
    context.PostInstance (instance)
    context.PostResult (MI_RESULT_OK)

@alinbalutoiu , thanks for fixing it! Eric has added in his PR and I have merged to master. We'll verify all issues after new build come.

Verified on private build.
