[Bug 1709314] Re: Unbreak size and archive size generation of built RPMs on big-endian systems

[Dimitri John Ledkov]

"Build an RPM on a 64-bit Big-Endian system on Ubuntu-Xenial" does not
at all make any sense at all. Why are you building RPMs on Ubuntu? is
this part of your test cases? You should be testing that you can builds
debs on Ubuntu, not RPMs. The only reason rpm tools are provided on
Debian (and thus Ubuntu) is to allow inspecting .rpm files for
informational purposes only (as if viewing a .jpg file).

Title:
  Unbreak size and archive size generation of built RPMs on big-endian
  systems

Status in Ubuntu on IBM z Systems:
  Invalid
Status in rpm package in Ubuntu:
  Confirmed

Bug description:
  We use the rpm tools version 4.12.0.1 that come with Ubuntu Xenial to build packages.
  However, that very version still has a bug:

  https://github.com/rpm-software-
  management/rpm/commit/104856ea17161eb3a508913c2b7ed701f2e4f6aa

  On Big-Endian systems (and that's what we use), the Archive-Size field is handled wrongly.
   
   
  ---uname output---
  Linux mclinx 4.4.0-83-generic #106-Ubuntu SMP Mon Jun 26 17:54:02 UTC 2017 s390x s390x s390x GNU/Linux
   
  Machine Type = IBM zSeries 2964 (z13) 
   
  ---Debugger---
  A debugger is not configured
   
  ---Steps to Reproduce---
   Build an RPM on a 64-bit Big-Endian system on Ubuntu-Xenial and check the Archive-Size field of the built RPM afterwards:

  rpm -qp --xml example-1.3.0-1.s390x.rpm > example_1.3.0-1_rpm.xml

  With the broken version you should find contents like these:

    <rpmTag name="Archivesize">
          <integer>0</integer>
    </rpmTag>

  In case the Archive-Size is lower than 4GiB you'll always see a "0" as value here. The corrected rpmbuild command should post the correct archive size.
