Sebastian Nagel commented on TIKA-3489:
---------------------------------------
The [robots.txt RFC draft|https://datatracker.ietf.org/doc/draft-koster-rep/]
requires "text/plain" as media type. Would be sound more straightforward to
just recognize a robots.txt file as "text/plain".
> Robots.txt files frequently identified as message/rfc822

> Key: TIKA-3489
> URL: https://issues.apache.org/jira/browse/TIKA-3489
> Project: Tika
> Issue Type: Bug
> Components: mime
> Affects Versions: 2.0.0, 1.25, 1.26, 1.27
> Reporter: Sebastian Nagel
> Priority: Minor
> Attachments: robots.txt
>
>
> The Tika MIME detector recognizes a robots.txt file as "message/rfc822" if
> the file starts with a "User-Agent" rule and contains also a second rule not
> too far away from the beginning, e.g.:
> {noformat}
> User-Agent: goodbot
> Disallow:
> User-Agent: badbot
> Disallow: /
> {noformat}
> The change
> [7769a2b|https://github.com/apache/tika/commit/7769a2b4fba2b4af7127eba0c7694f663fd97a13]
> requires that two different clauses are matched. However, the two
> occurrences of "User-Agent:" (initial and after a new line) are treated as
> different instead of equivalent matches.
