> Fix embedded stream translator to avoid changing file name
> ----------------------------------------------------------
>
> Key: TIKA-4617
> URL: https://issues.apache.org/jira/browse/TIKA-4617
> Project: Tika
> Issue Type: Task
> Reporter: Tim Allison
> Priority: Minor
>
> In 3.x, while reviewing the results in preparation for the next release, I
> noticed embedded ole file names were different between the last release and
> the current branch_3x.
> The cause of this difference is that we're now applying the stream
> translators on embedded oles when we run digesting. I had copy+pasted the
> stream translation code from tika-app or maybe tika-server's /unpack and not
> thought clearly enough about 2nd order consequences.
> During the digesting phase, the stream translators are modifying the embedded
> file name.
> We should fix this so that digesting doesn't modify the metadata at
> all...aside from adding digests.
> In looking at some of the other diffs, I think this causes quite a few second
> and third order problems. Once we fix this, I _think_ we'll have addressed
> most of the issues in the 3.x diffs.
