@IzzyOnDroid @SylvieLorxu I would be happy to see your repo become #FreeSoftware! As you well know, F-Droid only endorses verifiable free software projects.

It is also great to see all your work on #ReproducibleBuilds. We are continuing to build upon our years of effort there. Our approach is focused on identifying issues and getting things fixed upstream as much as possible. Then devs do not need to use any special tools to achieve reproducible builds.

@SylvieLorxu @IzzyOnDroid

Yes, there is plenty of low hanging fruit like embedded timestamps or nondeterministic ordering. Many apps are already easily reproducible or require only small fixes.

But the ecosystem is constantly moving: old toolchain and dependency bugs get fixed, but new ones keep popping up.

Reproducible Builds are not just an item on a checklist, something you (ask upstreams to) enable and then you're done. Especially when it's a hard requirement like at F-Droid where new builds no longer being reproducible means users will not be able to get updates.

It's an ongoing process involving not just upstream app developers, but also maintainers of repositories, clients, and rebuilders; those involved in outreach and writing documentation; developers and maintainers of tooling, toolchains, and dependencies. And often requires a lot of collaborative debugging :)

It requires teamwork and an ongoing commitment to investigate and fix new issues when they pop up.

So... this was a fun compiler bug: the D8 Java to DEX compiler (part of the Android toolchain) eliminated a redundant field load if running the class's static initialiser was known to be free of side effects, which ended up accidentally depending on the sharding of the input, which is dependent on the number of CPU cores used during the build.

issuetracker.google.com/issues…

I made a small example to illustrate why this optimisation is only valid when the class initialiser doesn't have side effects (or the initialiser is guaranteed to have run already, which is the case for a base class of the current one):
