---------------------------------
Summary: ZipDetector on a file should back off to streaming
detection on failure to open a zipfile
Key: TIKA-3701
URL: https://issues.apache.org/jira/browse/TIKA-3701
Project: Tika
Issue Type: Task
Reporter: Tim Allison
If a file is passed to Tika wrapped as a TikaInputStream with an underlying
file, the DefaultZipDetector tries to open a ZipFile. If there's a truncated
file or if that ZipFile open fails, the DefaultZipDetector effectively gives up.
Given that there's still a file available, we should try to do a streaming
detect by reopening the file as a regular InputStream.
If we don't do this, we wind up getting different detection for some truncated
ooxml if the user sends in a file vs a stream.
