archive size computed incorrectly on net-mounted filesystem
I've been testing makeself version 2.2.0. I noticed that --info always shows "Uncompressed size: 1 KB", no matter how much stuff is in the source directory. I added set -x and set -v to makeself.sh and saw that "du -sk
In the first example below note that "ls -l --blocksize=K" gives accurate block sizes for files on the net mount, but incorrectly gives 0 as the total size. "ls -ld --blocksize=K" gives "1" as the directory size, which matches the "du -sk" value, but disagrees with "ls -ld" on a non-net mount.
In the second (non-net) example the "du -sk" value is - correctly - the sum of the "ls -l" and "ls -ld" values. So, on my net mount both "du" and "ls -ld" return bogus total sizes, but "ls -l" can be relied on to return valid file sizes that can be added up. I don't know how to get a good directory sizing on the net mount.
Full disclosure: the filesystem is shared between VMWare VMs on a MacBook Pro, over localhost. Since the underlying medium is SSD, and the blocksize is virtualized, this may affect behavior.
Here's what I get on the net mount:
me@ubuntu:~/devshare/someplace/install/SXI-Linux$ du -sk source-files 1 source-files me@ubuntu:~/devshare/someplace/install/SXI-Linux$ ls -l --block-size=K source-files total 0K -rwxr-xr-x 1 501 dialout 6K Aug 6 14:57 config.sh -rwxr-xr-x 1 501 dialout 7K Aug 3 19:20 isysvd -rwxr-xr-x 1 501 dialout 142K Aug 3 14:53 pqos.exe -rwxr-xr-x 1 501 dialout 1K Aug 3 12:09 pqosSvc.env -rw-r--r-- 1 501 dialout 7K Aug 3 12:09 README me@ubuntu:~/devshare/someplacel/SXI-Linux$ ls -ld --block-size=K source-files drwxr-xr-x 1 501 dialout 1K Aug 6 14:57 source-files
Here's what I get on a non-net-mount:
me@ubuntu:/tmp$ du -sk source-files 176 source-files me@ubuntu:/tmp$ ls -l --block-size=K source-files total 172K -rwxr-xr-x 1 me me 6K Aug 6 16:33 config.sh -rwxr-xr-x 1 me me 7K Aug 6 16:33 isysvd -rwxr-xr-x 1 me me 142K Aug 6 16:33 pqos.exe -rwxr-xr-x 1 me me 1K Aug 6 16:33 pqosSvc.env -rw-r--r-- 1 me me 7K Aug 6 16:33 README me@ubuntu:/tmp$ ls -ld --block-size=K source-files drwxr-xr-x 2 me garybjerke 4K Aug 6 16:33 source-files
That's interesting, but aren't you basically just admitting that this is a problem with your system returning incorrect sizes, instead of with makeself itself? I'm pretty sure that --block-size option is not available outside of GNU ls. Actually, even the BSD version that comes with OS X doesn't support it so I would be reluctant to use that as an alternative.
Of course you're right about the portability issue.
I have no other network mount to test on, therefore no way to know if this is just a problem with my network share on OSX (a VMWARE share, actually, so VMWare hypervisor could be part of it). I probably just should have dropped you a note instead of opening a bug report. In any case, consider it something you might want to test independently.
If it's reproduceable on other network mounts, then it probably should be considered a bug.
Thanks for your time.
