Work Description: tcurdt commented on issue #87: COMPRESS-124 : Add
support for extracting sparse entries from tar archives
URL: https://github.com/apache/commons-compress/pull/87#issuecomment-559077121
While I appreciate being careful, I am not a fan of duplicating
functionality and interfaces like that. So I am in favor of just one class.
Maybe it means that testing needs to improved to be sure all is kept working.
Since @bodewig has the best overview over the project these days I think it
would be good to get input from him first.

> Unable to extract a sparse entries from tar archives
> ----------------------------------------------------
>
> Key: COMPRESS-124
> URL: https://issues.apache.org/jira/browse/COMPRESS-124
> Project: Commons Compress
> Issue Type: New Feature
> Components: Archivers
> Affects Versions: 1.1, 1.2
> Environment: Platform independent. However, I'm currently using
> Window 7 Enterprise.
> Reporter: Patrick Dreyer
> Priority: Major
> Labels: tar
> Attachments: gnuSparseFile.patch
>
> Time Spent: 2.5h
> Remaining Estimate: 0h
>
> Good news first: I already have the patch ready for that.
> I got several TAR files which I could not extract with any of the existing
> Java implementations, but I could extract all those TAR files successfully
> with GNU tar.
> It turned out that all the failing TAR files contained so called sparse
> files. Investigating the source code of all existing Java TAR implementations
> showed me that none of them even recognizes the existence of GNU sparse
> entries.
> Actually, I don't need to process one of the contained sparse files and I'm
> happy if I'm at least able to correctly untar all the non-sparsed files.
> Thus, it would be sufficient recognizing sparse files without the need to
> correctly un-sparse them while extracting. As long as all non-sparsed files
> get extracted correctly, I'm fine.
> The TAR files in question have all been VMware Diagnostic File bundles.
> See
> http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=653
> to know how to get them.
