Package: zip
Version: 2.31-2
Severity: wishlist
i found out that zip does not support files (and archives) greater than
2GB in size:
$ ls -la xaa2GB.img
-rw-r--r-- 1 root root 2193829888 May 9 17:20 xaa2GB.img
$ /usr/bin/zip test.zip xaa2GB.img
zip warning: name not matched: xaa2GB.img
zip error: Nothing to do! (test.zip)
strace confirms my assumption, as it shows no O_LARGEFILE calls:
$ strace /usr/bin/zip t.zip xaa2GB.img 2>&1 |grep LARGE
[empty]
(whereas "file" for example does use O_LARGEFILE:
$ strace file xaa2GB.img 2>&1 | grep LARGE | tail -n1
open("xaa2GB.img", O_RDONLY|O_LARGEFILE) = 3 )
appended patch fixes the issue (basically it just
adds -D_FILE_OFFSET_BITS=64 to CFLAGS)

result: zip works with files > 2GB now ;-)
$ strace ./zip t.zip xaa2GB.img 2>&1 |grep LARGE

open("xaa2GB.img", O_RDONLY|O_LARGEFILE) = 4
please consider applying this patch.
thank you,
Christian.
