Pathname too long about perl6-archive-libarchive

[hythm7]

I tested on home computer and I got the same error, However, I'm not able to reproduce it when using examples/archive.p6 /tmp/fileo.tar.xz $(find compiled-gcc-dir -type f) . at this point I think it might be something wrong with my code. I will do more testing and will post here when I have update.

it looks like the format v7tar is the culprit, changing the format to gnutar solved the issue.

I was able to reproduce by slighly modified `examples/archive.p6 to:

 #!/usr/bin/env perl6

use lib 'lib';
use Archive::Libarchive;

sub MAIN($fileo! where { ! .IO.f || die "file '$fileo' already present" },
         *@filei where { $_.all ~~ .IO.f || die "One of ( $_ ) not found" } )
{
  my Archive::Libarchive $a .= new: operation => LibarchiveWrite,
    format => 'v7tar', filters => ['xz'],
    file => $fileo;
  for @filei -> $file {
    try {
      $a.write-header($file, uname => 'user1', gname => 'group1');
      $a.write-data($file);
      CATCH {
        default { .Str.say }
      }
    }
  }
  $a.close;
}

and running:

hythm@galaxy$ perl6 ~/dev/perl6-Archive-Libarchive/examples/archive.p6 /tmp/fileo.tar.xz tools/x86_64-galaxy-linux-gnu/include/c++/9.1.0/ext/pb_ds/detail/cc_hash_table_map_/constructor_destructor_no_store_hash_fn_imps.hpp

Yes, the v7tar format has some limitations.
See https://github.com/libarchive/libarchive/blob/master/libarchive/archive_write_set_format_v7tar.c:
