Support systems with very old tar implementations.

[plicease]

Systems that use the "original" tar v7 format cannot grock the tarball produced by AB, because it has files with paths longer than 99 characters.

https://www.gnu.org/software/tar/manual/html_section/tar_67.html

HP-UX is apparently an affected system. I think just making the paths shorter should allow GNU tar to produce tarballs that the affected systems can read. If so then we should make the paths shorter, and add a test to ensure that paths are kept under 99 characters long. Can double check by trying to create a tarball with the --format v7 option with GNU tar. Supplying this option to a read of the tarball with GNU tar doesn't seem to reproduce the error seen on HP-UX.

tar: Exiting with failure status due to previous errors

[plicease]

Ah. Looks like bsdtar can be coerced into emitting a diagnostic on filenames that are too long, but, but it looks like it creates a tarball with truncated filenames and worse, doesn't exit with an error:

✅ starscream% bsdtar -cf Alien-Build-2.29.tar --format v7 Alien-Build-2.29

You will need something like

    macro        => { TARFLAGS   => "--format=ustar -c -v -f" },

in your Makefile.PL to address the issue for all non-GNU OS's/tar versions

[plicease]

@Tux Please try:

https://cpan.metacpan.org/authors/id/P/PL/PLICEASE/Alien-Build-2.31_01.tar.gz

This identifies as simply POSIX tar archive instead of POSIX tar archive (GNU).

✅ starscream% file ~/Downloads/Alien-Build-2.3*.tar
/home/ollisg/Downloads/Alien-Build-2.30_01.tar: POSIX tar archive (GNU)
/home/ollisg/Downloads/Alien-Build-2.31_01.tar: POSIX tar archive

If this works, then it looks like as a workaround I can use Dist-Zilla sans Archive::Tar::Wrapper. I suspect this may work because I think Dist-Zilla falls back on Archive::Tar if it doesn't have Archive::Tar::Wrapper. I don't use EUMM for authoring so amending Makefile.PL isn't an option.

If this doesn't work then it would be helpful to find a way to reproduce this error using Free or OpenSource tools, as like most people I do not have access to HP-UX machines.

A way to reproduce this using Free or OpenSource tools may also help when reporting this to Dist-Zilla and/or Archive-Tar-Wrapper.

[3:00:22 am] <[Tux]> plicease, looks sane

[plicease]

Waiting for a response
rjbs/Dist-Zilla#662
glasswalk3r/archive-tar-wrapper-perl#18

[plicease]

This should be resolved in 2.32 as workarounds have enacted in the release process while we wait for Dist-Zilla or Archive-Tar-Wrapper to respond.

@Tux please open issues for the other test fails you were seeing on HP-UX. If you can provide the verbose output (prove -lvm testname) that would be helpful.
