             Summary: TailFile in Single file mode does not work after restoring from state
                 Key: MINIFICPP-937
                 URL: https://issues.apache.org/jira/browse/MINIFICPP-937
             Project: Apache NiFi MiNiFi C++
          Issue Type: Bug
            Reporter: Daniel Bakai
             Fix For: 0.7.0
         Attachments: config.yml

To reproduce:
 * Create a TailFile - LogAttribute pipeline
 * Let it tail a few lines from the file
 * Restart minifi
 * TailFile will stop functioning (does not produce any FlowFiles even though there are lines added to the tailed file)

I think this might be related to the latest rewrite adding multiple modes and changing the state file format and parsing.

There is also a

{{[2019-06-27 11:30:05.523] [org::apache::nifi::minifi::processors::TailFile] [error] store state file failed}}

line in the log which indicates that the TailFile::storeState is sometimes called when state_file_ is empty (I have added extra logging to onTrigger, and the state_file_ variable is filled properly, so I don't know where is it exactly coming from).

I have also attached my config.yml: [^config.yml]
