-----------------------------------
Summary: Tika fails to detect ISO9660 disk images
Key: TIKA-900
URL: https://issues.apache.org/jira/browse/TIKA-900
Project: Tika
Issue Type: Bug
Components: mime
Affects Versions: 1.1
Environment: Any.
Reporter: Andrew Jackson
Priority: Minor
I have been testing Tika's ability to identify ISO9660 disk image file systems,
and discovered two problems. Firstly, the offset match matcher was wrong (37633
instead of 37633). Secondly, and more seriously, it was impossible for that
signaure to ever match, because the default buffer size was far to small. It is
currently set to 8KB, and as this signature is some 36KB into the file, Tika
could never find the match. The attached patch fixes the magic, and extends the
buffer to 64KB.
