Steve Rowe updated SOLR-3881:
-----------------------------
Attachment: SOLR-3881.patch
bq. I added code to {{LanguageIdentifierUpdateProcessor.initParams()}} to check
if {{maxFieldValueChars > maxTotalChars}}, and if so, set {{maxTotalChars}} to
the value of {{maxFieldValueChars}} and log a warning.
The above was too simplistic. If {{maxFieldValueChars > maxTotalChars}} and
the user only set {{maxTotalChars}}, then the reverse should happen:
{{maxFieldValueChars}} should be set {{maxTotalChars}}.
The attached patch fixes this, and allows the tests to pass.
