Description Bernhard Wiedemann 2022-07-18 07:44:42 UTC
While working on reproducible builds for openSUSE, I saw, doxygen picked up non-determinism from filesystem readdir order and therefore produces variations in build output


maybe also

At some point, there were also influences from ASLR, but these might have been solved earlier.

The easiest way to reproduce is to use my 'rbk' tool from
on a osc checkout

Alternatively, use osc build on two different ext4 filesystems in OSC_BUILD_ROOT=
or use disorderfs to ensure random readdir order.

I have a local checkout of home:pgajdos/doxygen and home:pgajdos/libzypp. Now I have a patch there against doxygen and would like to test it, is it possible with rbk tool? d.o.o/repositories/home:/pgajdos/openSUSE_Factory/x86_64/ says it is doxygen-1.9.4-178.1, but rbk build still seems to pick doxygen-1.9.4-1.1 instead.

I have
: ${project:=home:pgajdos}
: ${repo:=openSUSE_Factory}
in rbk script and


in osc meta prj.
