Description (last modified by )
A disc I burned on my Mac appears to have major interpretation problems with our iso9660 driver. The actual contents of the disc look as follows:

4 File(s) 364,670,840 bytes
0 Dir(s) 0 bytes free
However, our iso9660 add-on claims this instead:

None of the files are usable. Syslog of that CD insertion:

Let me know if you need any other information, I can make these discs pretty much at will.

Another note of interest: FreeBSD lists the entries twice also, but with a slight name difference:

Note also that the sizes on the =-prefixed names match the ones reported on Haiku. The second set are correct though.

Will try and see how small a disc I can replicate that problem with, as you can see the current one is 300MB of image data so it wouldn't really compress well. If I can make a small one of just the jpegs with the same issue after work, I'll put it on Vision's sourceforge page and post the link here.

Replying to axeld:
Would it be possible to upload a small ISO somewhere?
http://vision.sf.net/problem.iso.zip
Should be 39765799 bytes and have an md5 hash of: 1f08bfaa60286079248e3f7dc575e783 .
This one displays the same characteristics in FreeBSD as the listing in the ticket description, but also has the fun property that it causes Haiku's ISO9660 add-on to KDL with a page fault when you attempt to list it (mounting does work though).

The iso9660_shell (available again since hrev30639) does not exhibit the crash, but otherwise shows the same problem. Should be easier to debug there.

Cool, let me know if you need anything else for reference. As far as I can tell any CD I burn via OSX Leopard's Finder shows the exact same dir structure problems, though the KDL seems to be hit or miss.
comment:10 by , 15 years ago
The crashing part is fixed in hrev30640 - this bug was probably hidden by the userland allocator.

The data accessible from Haiku looks like the MacOS resouce forks, at least that's what I would assume.

Ahh, that's entirely possible. Is the function that sanitizes filenames by any chance stripping out a filename prefix character that OSX uses to differentiate between the file and the resource data here by any chance?
comment:13 by , 15 years ago
Some issues with this ISO image are fixed in hrev30655. However, the file data and length is still bogus - apparently, we don't support ISO level 3 extents.
The archive manager/mounter combo under Ubuntu also has its problems with this ISO, btw.
follow-up: 15 comment:14 by , 15 years ago
On second thought, though, it can't really be an ISO level 3 problem, as the highest bit of the flags field is not set. Maybe something with the block size; the files are not just too small, they also seem to have the wrong contents; the actual file content does not contain whatever we see in Haiku.

Would it help debugging at all to have another ISO to compare against with a different set of files? Nice work so far in any case :)

No thanks, I guess besides time I have everything I need :-)
Maybe someone else comes along with a fix in the mean time ;-))
Also, trace log from when running the ls -la that resulted in the above output:
