This process has to be deterministic regarding which file is the "original", otherwise the rpm comparision of the current build result and a previous run will have the false result. fdupes 1.40 had a SUSE specific patch to sort by filename. This patch was dropped for fdupes-1.50, which sorts by mtime, which was considered good enough. Unfortunately mtime sorting is not stable, as files may be created in parallel during the build. Reproducible: Always Steps to Reproduce: 1. build a package on obs Actual Results: This is as excerpt from a Mesa build log: [ 1289s] /usr/share/man/man3/glColorTableParameter.3gl.gz 2 (none) 100444 root root 0 4294967295 [ 1289s] -/usr/share/man/man3/glColorTableParameterfv.3gl.gz 2 (none) 100444 root root 0 4294967295 [ 1289s] -/usr/share/man/man3/glColorTableParameteriv.3gl.gz 2 (none) 120777 root root 0 4294967295 glColorTableParameterfv.3gl.gz [ 1289s] +/usr/share/man/man3/glColorTableParameterfv.3gl.gz 2 (none) 120777 root root 0 4294967295 glColorTableParameteriv.3gl.gz [ 1289s] +/usr/share/man/man3/glColorTableParameteriv.3gl.gz 2 (none) 100444 root root 0 4294967295 [ 1289s] /usr/share/man/man3/glConvolutionFilter1D.3gl.gz 2 (none) 100444 root root 0 4294967295 glColorTableParameterfv.3gl.gz and glColorTableParameteriv.3gl.gz are identical, but the symlink direction has changed. Expected Results: Symlink direction should be deterministic. A patched fdupes (optional sorting by filename, activated in the %fdupes macro by default) is available in the utilities:fdupes repository Affects openSUSE 12.3 and 13.1. fdupes should be updated in 12.3 and 13.1 as it reduces rebuilds on obs and avoids unnecessary package updates/downloads for users having additional repositories.
