Hello,
I am having trouble when doing atomic updates in combination with
SignatureUpdateProcessorFactory (on Solr 7.2). Normal commits of new
documents work as expected and generate a valid signature:
curl "$URL/update?commit=true" -H 'Content-type:application/json' -d
'{"add":{"doc":{"id": "TEST_ID1", "description": "description",
"country": "country"}}}' && curl "$URL/select?q=id:TEST_ID1"
"response":{"numFound":1,"start":0,"docs":[
{
"id":"TEST_ID1",
"description":["description"],
"country":["country"],
"_signature":"e577e465b9099ba8", <-- valid signature
"_version_":1608322850016460800}]
}}
However, when updating a field (that is not used for generating the
signature) the signature is replaced by "0000000000000000":
curl "$URL/update?commit=true" -H 'Content-type:application/json' -d
'{"add":{"doc":{"id": "TEST_ID1", "country": {"set": "country2"}}}}' &&
curl "$URL/select?q=id:TEST_ID1"
"response":{"numFound":1,"start":0,"docs":[
{
"id":"TEST_ID1",
"description":["description"],
"country":["country2"],
"_signature":"0000000000000000", <-- broken signature
"_version_":1608322857485467648}]
}}
This looks a lot like the second problem mentioned in an old Solr JIRA
issue ([1]). Unfortunately, there is no relevant response in the
discussion there.
Any ideas how to fix this?
Thank you,
Thomas
