[MASSEMBLY-1032] should be able to create ustar archives (i.e. non-posix/non-GNU)

[jira-importer]

Benjamin Marwell opened MASSEMBLY-1032 and commented

Currently, the tar option will always create POSIX archives or GNU archives.
However, not all implementations of tar can handle this: https://savannah.gnu.org/support/?109437

AIX 7.2 will unpack Directories named PaxHeaders.X, not sure about what happens with GNU tar archives.

However, given that ustar is more universal until AIX 7.3.1 arrives, it would be a reasonable option to support ustar as well. Even after that AIX release, it might be a reasonable choice for other Unix-like systems, as the posix standard has not been adopted widely.

I just saw that ustar does not seem supported by Commons-Compress? Also, there is an plexus abstraction layer inbetween.

I have seen the issue with PaxHeaders on HP-UX version of tar as well. It was too bad, replaced with gtar/libarchive.

The underlying issue is that commons-compress does not support that. But I heard the new AIX tar can properly expand PAX/POSIX tar archives without relying on GNU tar and/or the pax tool. So maybe this will be unneeded.

also blocked by the plexus wrapper. Really questionable whether this is worth it.
