Stefan Bodewig commented on COMPRESS-16:
----------------------------------------
I plan to look up what the GNU tar implementation does, may take a few days,
though.
I agree with Gili this issue has by now outgrown COMPRESS-16 as it specifically
only dealt with lengths. OTOH it is not restricted to star either, if we start
supporting "bigger numbers" for group or date, we should support star as well
as PAX.

> I made a TAR file which contains a file entry where the file is 10 GB in size.
> When I attempt to extract the file using TarInputStream, it fails with the
> following stack trace:
> java.io.IOException: unexpected EOF with 24064 bytes unread
> at
> org.apache.commons.compress.archivers.tar.TarInputStream.read(TarInputStream.java:348)
> at
> org.apache.commons.compress.archivers.tar.TarInputStream.copyEntryContents(TarInputStream.java:388)
> So, TarInputStream does not seem to support large (> 8 GB?) files.
> Here is something else to note: I created that TAR file using TarOutputStream
> , which did not complain when asked to write a 10 GB file into the TAR file,
> so I assume that TarOutputStream has no file size limits? That, or does it
> silently create corrupted TAR files (which would be the worst situation of
> all...)?
