Subject: 7zip: add ArchiveProperties payload test
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=49a273e31408231177aacf2ee405baefb84babff;p=thirdparty%2Flibarchive.git

7zip: add ArchiveProperties payload test

Add a 7z test archive with a non-empty ArchiveProperties payload.

The archive has one empty file and an ArchiveProperties entry with a
1-byte payload. It is accepted by 7-Zip/7zz.

This covers parsing when ArchiveProperties has payload bytes.
