# RT #92205: CRC error when re-writing Zip created by LibreOffice
# Archive::Zip was blowing up when processing member
# 'Configurations2/accelerator/current.xml' from the LibreOffice file.
#
# 'current.xml' is a zero length file that has been compressed AND uses
# streaming. That means the uncompressed length is zero but the compressed
# length is greater than 0.
#
# The fix for issue #101092 added code that forced both the uncompressed &
# compressed lengths to be zero if either was zero. That caused this issue.
# This set of test checks that a zero length zip member will ALWAYS be
# mapped to a zero length Stored member, regardless of the compression
# method used or the use of streaming.
#
#
# Input files all contain a single zero length member.
# Streaming & Compression Method are set as follows.
#
# File Streamed Method
# ===============================================
# emptydef.zip No Deflate
# emptydefstr.zip Yes Deflate
# emptystore.zip No Store
# emptystorestr.zip Yes Store
#
# See t/data/mkzip.pl for the code used to create these zip files.
