[Bug 686414] Re: dpkg build corrupted packages, if package size is over 2 GB

[DoohGuy]

I'm sorry to report that this bug is still unresolved in Natty.  I'm
using dpkg 1.16.1 and the procedure to reproduce is:

Create a directory structure like this:

debian/
debian/DEBIAN
debian/DEBIAN/control
debian/DEBIAN/postinst
debian/usr/
debian/usr/local/
debian/usr/local/HUGE-FILE-BIGGER-THAN-2GB

Then create the deb with:

fakeroot dpkg-deb --build debian

Which completes without error, however, the resulting deb is corrupted.

ar -t debian.deb
ar: debian.deb: Malformed archive

Title:
  dpkg build corrupted packages, if package size is over 2 GB

Status in “dpkg” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: dpkg

  I tried to build a binary package from a Xilinx ISE installation. The program have a size about 7.4 GB.
  I copied the whole installation tree to a folder in /tmp/ created a DEBIAN folder, the required control file and build the package with:
  fakeroot
  dpkg -b deb xilinx-ise-12.1-all.deb

  As result the package is created, it have a size of 2,5 GB. No error
  message occur. So i assumed everything is fine.

  But when you try to install the package you get the error message: 
  (Lese Datenbank ... 125854 Dateien und Verzeichnisse sind derzeit installiert.)
  Entpacke xilinx-ise (aus xilinx-ise-12.1-all.deb) ...
  dpkg-deb: Datei »xilinx-ise-12.1-all.deb« ist defekt - falsche Kennung am Ende der ersten Kopfzeile
  dpkg: Fehler beim Bearbeiten von xilinx-ise-12.1-all.deb (--install):
   Unterprozess dpkg-deb --fsys-tarfile gab den Fehlerwert 2 zurück
  Fehler traten auf beim Bearbeiten von:
   xilinx-ise-12.1-all.deb

  Also opening the package with an archive manager fails. I used File
  Roller 2.30.1.1 for this task. It reports the error: "... Malformed
  archive"

  
  I guess the problem is the size of the archive. So I disperse the installation on three packages each under 1 GB. It works all fine when installing these three packages.
