[Bug 845716] Re: APT fails on packages >= 2 GB

[David Kalnischkies]

Using ssize_t doesn't help 32bit systems as ssize_t is only on 64bit
systems larger than an int.

Either way, the issue should be fixed in a newer release of APT, see LP:
#250909 and debians APT version 0.7.26~exp6 for details. It might be
possible that this is not completely fixed for everyone through as
debugs #632271 suggests which is only fixed in debian experimental for
now (as these kind of changes make an abi break nessary and are
therefore out of question for a sane backport).

It would be cool if you could test these versions and report back. I am
closing this bug in the meantime. If it is really not fixed in newer
versions please reopen!

Title:
  APT fails on packages >= 2 GB

Status in “apt” package in Ubuntu:
  Invalid

Bug description:
  Ubuntu 10.04 apt-0.7.25.3ubuntu9.6

  "apt-get install <package>" fails when trying to install packages
  larger than approximately 2 GB.

  The reason is that APT uses incorrect data types - it counts bytes in
  floating point(!) as well as signed 32-bit variables, and uses atoi()
  to convert string representations of sizes to numbers.

  The attached patch makes APT use ssize_t and atol().

  Symptoms when installing from a private repository containing large
  packages:

  # apt-get install matlab2011b

  The following extra packages will be installed:
