> Key: DS-1137
> URL: https://jira.duraspace.org/browse/DS-1137
> Project: DSpace
> Issue Type: Improvement
> Components: DSpace API
> Affects Versions: 1.7.0, 1.7.1, 1.7.2, 1.8.0, 1.8.1, 1.8.2, 3.0
> Reporter: Tim Donohue
> Priority: Major
> Fix For: 4.0
>
>
> This improvement request is based on a dspace-tech email thread:
> http://www.mail-archive.com/[email protected]/msg16350.html
> Essentially, in Java 6 and below, Java Zip (java.util.zip) has file size
> limitations. The Zip file itself cannot be more that 4GB in size.
> In Java 7, this has been fixed so that Zip64 is now supported
> (https://blogs.oracle.com/xuemingshen/entry/zip64_support_for_4g_zipfile).
> However, in any case, the AIP Packager should also support TAR or TAR.GZ
> (TGZ) as an option.
> This change would likely necessitate the following:
> (1) Change the 'writeZipPackage()' method of
> 'org.dspace.content.packager.AbstractMETSDisseminator' so that it is
> configurable to use either:
> - java.util.zip.ZipOutputStream (and associated classes)
> - OR, org.apache.commons.compress.archivers.tar.TarArchiveOutputStream
> (and associated classes)
> (2) Change the 'parsePackage()' method of
> 'org.dspace.content.packager.AbstractMETSIngester' so that it is also
> configurable to use either:
> - java.util.zip.ZipInputStream (and associated classes)
> - OR, org.apache.commons.compress.archivers.tar.TarArchiveInputStream
> (and associated classes)
> I've not tried this change, so more classes may be affected.
> Ideally, this would be made configurable, so that institutions could choose
> whether to use Zip or Tar. As an example, see how the Replication Task
> Suite's BagIt packer can support either Zip or TGZ archiving format:
