Subject [jira] [Commented] (COMPRESS-132) Add support for unix dump files
Date Wed, 17 Aug 2011 15:56:27 GMT

    [ https://issues.apache.org/jira/browse/COMPRESS-132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13086412#comment-13086412

Stefan Bodewig commented on COMPRESS-132:
-----------------------------------------

I've added dump support on the base of the current trunk code to the Compress Antlib[1]'s
trunk and its different type of test archive works as well.

So I see autodetection and docs as the only things missing to close this, yay.

The current javadocs say we'd support BZIP2 (in package.html), but this is not true, is it?

> 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.
