Subject: warc: test missing file size handling
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=366baca7184d348c75250a3ef04bb7089518a007;p=thirdparty%2Flibarchive.git

warc: test missing file size handling

Add coverage for WARC entries without a known size. The writer
must reject these entries because WARC requires Content-Length.
