David Handermann updated NIFI-4718:
-----------------------------------
Summary: Improve Detection of FlowFile V3 in IdentityMimeType (was:
IdentifyMimeType: increase priority for FFv3)
> Improve Detection of FlowFile V3 in IdentityMimeType
> ----------------------------------------------------
>
> Key: NIFI-4718
> URL: https://issues.apache.org/jira/browse/NIFI-4718
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Reporter: Brandon Rhys DeVries
> Assignee: Nissim Shiman
> Priority: Minor
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> IdentifyMimeType uses tika configured with a custom-mimetypes.xml\[1] to
> specify (among others) the flowfile-v* mime types. However, these do not
> include priorities. Therefore, a NiFi FlowFile V3 package with a payload
> containing, for example, html including the string:
> {code}
> <html xmlns=
> {code}
> will be identified as "application/xhtml+xml" \[2] which, while matching the
> pattern, is not as correct as identifying it as application/flowfile-v3. To
> fix this, I believe we need to specify a higher priority for the FlowFile V3
> "magic"...
