allow data descriptors to follow STORED entries in ZIP archives being read
--------------------------------------------------------------------------
Key: COMPRESS-103
URL: https://issues.apache.org/jira/browse/COMPRESS-103
Project: Commons Compress
Issue Type: New Feature
Affects Versions: 1.0
Reporter: Stefan Bodewig
Priority: Minor
the document named "Word XPS.xps" found under
http://www.wssdemo.com/XPS/Forms/AllItems.aspx contains at least one STORED
entry that uses a data descriptor after the entries' data to hold size and CRC
information.
The ZipFile class uses information from the central directory and thus knows
the size of the entry and can deal with the archive. ZipArchiveInputStream
currently can't.
One solution would be to read the entry until we hit the signature of a data
descriptor, local file header or the start of the central directory. If we hit
another LFH or the CD then the data descriptor didn't use the signature (see
COMPRESS-101 ) and the last 12 bytes read have already been the data
descriptor. This will certainly not be very efficient.
