LibreOffice success story

[Bernhard M. Wiedemann]

Dear fellow R-B-ings

Just 2 weeks ago, when I re-reviewed the remaining ~120 major issues in 
openSUSE, I pretty much skipped over LibreOffice (and only this one), 
noting it down as "various issues", because some years ago, when I had 
previously taken a closer look, there had been so many issues in files 
of various formats and additionally the build of that large package took 
hours, so that I had quickly stopped debugging and left it "for later".

Then on the r-b-summit I met Thorsten from LibreOffice upstream and 
together we reviewed the old diff I had from 2022 [1]. We noticed that 
there was an issue with docs, but I had recently made
https://code.opensuse.org/package/doxygen/blob/master/f/reproducible.patch
that turned out to solve this exact issue. It still needs upstreaming.

There was a timestamp-issue from long-orphaned clucene and we found 3 
others that Thorsten quickly fixed:
https://gerrit.libreoffice.org/q/topic:reprobuild

Now there were only mtimes left in .jar and .zip files that were easily 
normalized with strip-nondeterminism.

So today I hold in my hands the first two bit-identical LibreOffice rpm 
packages.
And this is the success I wanted to share with you all today.

It makes me feel as if we can solve anything.

Ciao
Bernhard M.
