Ben Pennell created SOLR-4294:
---------------------------------
Summary: Solr 4 atomic update incorrect value when setting two or
more values to a multivalue via XML update
Key: SOLR-4294
URL: https://issues.apache.org/jira/browse/SOLR-4294
Project: Solr
Issue Type: Bug
Components: clients - java, update
Affects Versions: 4.0
Environment: RHEL
Reporter: Ben Pennell
Priority: Minor
Fix For: 4.0.1, 4.1
Setting multiple values to a multivalued field via an XML atomic update request
is resulting in what appears to be the output of a toString() method. See the
examples below.
I ran into this issue using the output for atomic updates from the fix for
Solr-4133 to ClientUtils. The server being used is the base 4.0.0 release.
{code}
curl 'https://localhost/solr/update?commit=true' -H 'Content-type:text/xml' -d '
<add><doc boost="1.0">
<field name="id">test</field>
<field name="status" update="set">one</field>
<field name="status" update="set">two</field>
</doc></add>'
{code}
Yields the following in Solr:
{code}
<arr name="status"><str>{set=one}</str><str>{set=two}</str></arr>
{code}
Changing the second "set" to an "add" has the same effect.
If I only set one value though, it works correctly:
{code}
<add><doc boost="1.0">
<field name="id">test</field>
<field name="status" update="set">one</field>
</doc></add>
{code}
Yields:
{code}
<arr name="status"><str>one</str></arr>
{code}
It also works fine if I split it into two operations
{code}
<add><doc boost="1.0">
<field name="id">test</field>
<field name="status" update="set">one</field>
</doc></add>
<add><doc boost="1.0">
<field name="id">test</field>
<field name="status" update="add">two</field>
</doc></add>
{code}
Yields:
{code}
<arr name="status"><str>one</str><str>two</str></arr>
{code}
Oddly, it works fine as a singe request in JSON:
{code}
curl -k 'http://localhost/solr/update?commit=true' -H
'Content-type:application/json' -d '["id":"test", {"status":{"set":["one",
"two"]}}]'
{code}
Yields:
{code}
<arr name="status"><str>one</str><str>two</str></arr>
{code}
