unzip bug?

[ogniemi]

I met a problem with unziping file when the extracted file is greather than 2GB.

I tried several unzip versions with the same result.

The filesystem is jfs2 type and user has file limit "unlimited" "file(blocks) unlimited"

Of course I can manually create files greather thna 2GB so I think this must be the unzip bug.

Under the MS Windows the file can be unpacked without any problems.

Any idea how to fix the issue on AIX? (an application works with zip files).

Thank you in advance!

(below problem reproduced with latest unzip)

user@testsystem:/home/user$ ls -al
total 1263176

drwxr-xr-x 3 user staff 4096 Nov 24 01:43 ..

user@testsystem:/home/user$
user@testsystem:/home/user$ unzip -t -P password myarchivefile.ZIP

user@testsystem:/home/user$ unzip -P password myarchivefile.ZIP

myarchivefile: write error (disk full?). Continue? (y/n/^C)


On the other screen I have been observing filesystem usage:

$ while true;do df -g .|grep -v ^Filesystem;sleep 5;done
/dev/hd1 15.00 3.99 74% 30882 4% /home

/dev/hd1 15.00 1.99 87% 30883 7% /home


And when unzip errored and prompted, I saw in the directory only 2GB file!!

Which unzip versions have you tried? I would think you'd need a pretty recent version in order to have large file enabled both on the zipfile side and the extracted file side...

Perhaps you need to build your own executable?


HTH,

when building your own add -D_POSIX_SOURCE -D_LARGE_FILES -D_LARGE_FILE_API for large files

p5wizard,
I tested the recent one: UnZip 5.52 (downloaded from

http://computer-refuge.org/classiccmp/aixpdslib/pub/

)

mrn,
thanks for the tip. I will try it.
