Bug #70856 for Archive-Zip: Add Zip64 support

Fri Sep 09 18:37:23 2011 ejtrochim [...] alaska.edu - Ticket created

Subject:

Add Zip64 support

Archive::Zip does not support the Zip64 format which is required to read and write archives greater than 4GB, have members with compressed/uncompressed sizes over 4GB or have more than 65,535 members in an archive. Currently, Archive::Zip will fail to read in a Zip64 archive, claiming it encountered a bad signature. Additionally, Archive::Zip will produce an archive with corrupted metadata in the central directory if it attempts to create an archive that exceeds any of the above limits.

To help people googling with the error message — here's how a stack trace looks like when Archive::Zip tries to read such a file: format error: bad signature: 0x031e0201 at offset 4456518 in file /tmp/64k.zip at /usr/local/lib/perl5/site_perl/5.12.4/Archive/Zip.pm line 477 Archive::Zip::_readSignature('IO::File=GLOB(0x8029e4630)', '/tmp/64k.zip') called at /usr/local/lib/perl5/site_perl/5.12.4/Archive/Zip/Archive.pm line 603 Archive::Zip::Archive::readFromFileHandle('Archive::Zip::Archive=HASH(0x801812648)', 'IO::File=GLOB(0x8029e4630)', '/tmp/64k.zip') called at /usr/local/lib/perl5/site_perl/5.12.4/Archive/Zip/Archive.pm line 548 Archive::Zip::Archive::read('Archive::Zip::Archive=HASH(0x801812648)', '/tmp/64k.zip') called at /usr/local/lib/perl5/site_perl/5.12.4/Archive/Zip/Archive.pm line 51 Archive::Zip::Archive::new('Archive::Zip::Archive', '/tmp/64k.zip') called at /usr/local/lib/perl5/site_perl/5.12.4/Archive/Zip.pm line 287 Archive::Zip::new('Archive::Zip', '/tmp/64k.zip') called at /tmp/64kzip.pl line 23 Regards, Slaven

As an alternative, IO::Compress::Zip and IO::Uncompress::Unzip support Zip64 files. Regards, Slaven

Slaven, thanks for posting what the stack trace looks like & what alternatives exist. It indeed helped me at Google-time.

Thanks for bringing this issue up - I'm looking at how to implement this. Any pointers you have (no pun intended) would be helpful. On Wed Dec 19 14:09:24 2012, SREZIC wrote: Show quoted text

Patches very welcome. Just became a dad for the second time, so I don't have the bandwidth to implement this anytime soon On Wed, Aug 22, 2018, 5:11 AM Phil Harvey via RT < bug-Archive-Zip@rt.cpan.org> wrote: Show quoted text
