#3392 imm: incorrect value when load empty value from xml file

[Thien Minh Huynh]

Expectation when create new object, default value assign if set NULL.
But immcfg -f <xml file> does not work as expect if contain empty tag

Reproduce steps:
* Load xml file: immcfg -f <xml file below>
* Expected value after loaded is default value (15)

Hi Thien,
I change a little of xml file to

<?xml version="1.0"?>
<imm:IMM-contents xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="SAI-AIS-IMM-XSD-A.02.13.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:imm="http://www.saforum.org/IMMSchema">
  <class name="Test">
    <category>SA_CONFIG</category>
    <rdn>
      <name>test</name>
      <type>SA_STRING_T</type>
      <category>SA_CONFIG</category>
      <flag>SA_INITIALIZED</flag>
    </rdn>
    <attr>
      <name>limitTime</name>
      <type>SA_UINT32_T</type>
      <category>SA_CONFIG</category>
      <flag>SA_WRITABLE</flag>
      <default-value>15</default-value>
    </attr>
  </class>
  <object class="Test">
    <dn>test=1</dn>
    <attr>
      <name>limitTime</name>
      <value xsi:nil="true"/>
    </attr>
  </object>
  <object class="Test">
    <dn>test=2</dn>
    <attr>
      <name>limitTime</name>
      <value></value>
    </attr>
  </object>
</imm:IMM-contents>

And it shows that

root@SC-1:~# immlist test=1
Name                                               Type         Value(s)

root@SC-1:~# immlist test=2
Name                                               Type         Value(s)
========================================================================
test                                               SA_STRING_T  test=2
limitTime                                          SA_UINT32_T  0 (0x0)
SaImmAttrImplementerName                           SA_STRING_T  <Empty>
SaImmAttrClassName                                 SA_STRING_T  Test
SaImmAttrAdminOwnerName                            SA_STRING_T  <Empty>

Please check whether it is expected behavior.

Hi Thang,

The input from xml "<value xsi:nil="true">" is valid. The output of immlist test=1 is expected.
limitTime SA_UINT32_T 15 (0xf)</value>

The input from xml "<value></value>" is valid. But the output of immlist test=2 is not expected.
limitTime SA_UINT32_T 0 (0x0)

Hi Thang,

I have updated to handle use case that you mentioned.

Best Regards,

imm: correct xml parser to SaImmAttrValuesT_2 [#3392]

imm import does not handle parse empty tag.
This commit just handles parsing empty tags to SaImmAttrValuesT_2.

[Thien Minh Huynh]

Hi Thang,
Sorry, I want to correct this use case.

<object class="Test">
    <dn>test=2</dn>
    <attr>
      <name>limitTime</name>
      <value></value>
    </attr>
  </object>

This is not considering a valid empty/nil use case. It violates with empty data if data type of string is empty. That what xsi:nil="true" introduced.

Example:

<attr>
      <name>limitTime</name>
      <type>SA_STRING_T</type>
      <category>SA_CONFIG</category>
      <flag>SA_WRITABLE</flag>
      <default-value>15</default-value>
    </attr>
<attr>
<name>limitTime</name>
      <value></value>
 </attr>

This is empty data. not consider null.

Best Regards,
Thien

imm: correct handle null when load xml file [#3392]

Only accept handle null when has an attribute xsi:nil="true"
Not handle null in case <value></value>
