Tim Allison created TIKA-2873:
---------------------------------
Summary: Password protected xlsx file no longer opens with password
Key: TIKA-2873
URL: https://issues.apache.org/jira/browse/TIKA-2873
Project: Tika
Issue Type: Task
Reporter: Tim Allison
A password protected .xlsx file can no longer be read because there's a bug
in POI's ChunkedCipherInputStream:
{noformat}
@Override
public int read() throws IOException {
byte[] b = \{ 0 };
// FIXME: compare against -1 or 1? (bug 59893)
return (read(b) == 1) ? -1 : b[0];
}
{noformat}
Reading with a byte[] works fine, but read() individual bytes returns -1 if
the stream had something in it. Because of some recent changes...we now wrap
the ChunkedCipherInputStream in a RereadableInputStream...whereas we didn't
before...this wrapping is now calling {{read()}} at some point where the stream
used to only be {{read(byte[])}}. We can fix this by wrapping the
ChunkedCipherInputStream in a TikaInputStream...
I think this is significant enough to do a respin of 1.21-rc1...what do you
think?
