Subject: Verify that Zip writer rejects too-large files when Zip64 is disabled.
X-Git-Tag: v3.1.900a~327^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=refs%2Fpull%2F62%2Fhead;p=thirdparty%2Flibarchive.git

Verify that Zip writer rejects too-large files when Zip64 is disabled.

Interestingly, this found a bug in the write core:  if the
writer rejects a file, the write core would erroneously transition to
state DATA.
