Subject [jira] [Commented] (COMPRESS-132) Add support for unix dump files
Date Tue, 16 Aug 2011 13:57:32 GMT

    [ https://issues.apache.org/jira/browse/COMPRESS-132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13085707#comment-13085707
] 

Bear Giles commented on COMPRESS-132:
-------------------------------------

I used a loopback filesystem

   # truncate -s 4g test1fs  (creates large sparse file)
   # losetup /dev/loop7 test1fs
   # mkfs.ext2 /dev/loop7
   # losetup -d /dev/loop7
   # mount -oloopback test1fs /mnt
   # (populate partition with test data)
   # dump ...  (note: mount will probably mount on a different loopback 
device)

(or something like that - I may have various arguments reversed)

> I'm submitting a series of patches to the ext2/3/4 dump utility and noticed that the
commons-compress library doesn't have an archiver for it. It's as old as tar and fills a similar
niche but the later has become much more widely used. Dump includes support for sparse files,
extended attributes, mac os finder, SELinux labels (I think), and more. Incremental  dumps
can capture that files have been deleted.
> I should have initial support for a decoder this weekend. I can read the directory entries
and inode information (file permissions, etc.) but need a bit more work on extracting the
content as an InputStream.
