> Preserve "x-tika-ooxml" mime value for truncated ooxml files
> ------------------------------------------------------------
>
> Key: TIKA-2311
> URL: https://issues.apache.org/jira/browse/TIKA-2311
> Project: Tika
> Issue Type: Bug
> Reporter: Tim Allison
> Fix For: 2.0, 1.15
>
>
> The following is an unintended consequence of TIKA-2212.
> The OOXML parser used to handle {{x-tika-ooxml}}. We have some truncated
> ooxml files in our regression corpus. The previous behavior was:
> 1) ZipPackage detector caught the zip truncation exception and returned
> "application/zip"
> 2) The mime detector recognized magic and returned {{x-tika-ooxml}}
> 3) The file was then routed to the OOXML parser which didn't wind up doing
> much with the content because it hit the zip exception early on, but the
> final mime type was {{x-tika-ooxml}}.
> The current behavior
> 1) Same detection steps
> 2) However, because the OOXML parser no longer handles {{x-tika-ooxml}}, the
> file is handled by the Package Parser, which overwrites the magic-determined
> mime type, and the new mime type is {{application/zip}}.
> 3) Some content is extracted because the Package parser handles the zip
> entries in order and only throws the exception once it hits the last entry in
> the zip file.
> Ideally, I'd like to keep the magic-determined mime detection. Once we can
> chain parsers, the user should be able to backoff to the PackageParser, but I
> don't think this should be the default behavior.
> One solution would be to create a new mime type that is not the parent of the
> other ooxml subtypes, but is itself a leaf subtype, something like:
> {{x-tika-ooxml-unk}}.
> Any objections/other recommendations?
