New issue 70 by tyson.key: XAR chokes when attempting to restore Samba/NTFS
Streams-specific extended attributes
http://code.google.com/p/xar/issues/detail?id=70
What steps will reproduce the problem?
1. Share a directory via SMB using Samba under Mac OS X 10.5.6
2. Using a Windows XP box, create an empty text file inside the shared
directory
3. Set the Category attribute on aforementioned text file, and let Samba
add three new Mac OS X Extended Attributes
(:DOCUMENTSUMMARYINFORMATION:$DATA:, :SUMMARYINFORMATION:$DATA: and
:{4C8CC155-6C1E-11D1-8E41-00C04FB9386D}:$DATA:)
4. Attempt to archive said text file using "xar -c -v -f NTFS1.rar
TextDoc1.txt" inside the shared directory
5. Observe that XAR claims to have successfully archived the file
6. Dump the TOC to stdio using "xar --dump-toc=- -f NTFS.rar ", and notice
that an XML parsing error is produced
What is the expected output? What do you see instead?
I expect to see the contents of the TOC, complete with references to
aforementioned extended attributes. In addition, XAR should not simply
ignore these attributes when a directory containing multiple files with
them is archived.
Extracting the archive should result in a file with extended attributes
along the lines of:
xattr -l TextDoc1.txt
