qt6Packages.qtdeclarative: does not build reproducibly #230291

Closed raboof closed 8 months ago

raboof commented 1 year ago

Building this package twice does not produce the bit-by-bit identical result each time, making it harder to detect CI breaches. You can read more about this at https://reproducible-builds.org/ .

Fixing bit-by-bit reproducibility also has additional advantages, such as avoiding hard-to-reproduce bugs, making content-addressed storage more effective and reducing rebuilds in such systems.

Steps To Reproduce

nix-build '<nixpkgs>' -A qt6Packages.qtdeclarative --check --keep-failed

You can use diffoscope to analyze the differences in the output of the two builds.

To view the build log of the build that produced the artifact in the binary cache:

nix-store --read-log $(nix-instantiate '<nixpkgs>' -A qt6Packages.qtdeclarative)

This just failed to build for me just now (at nixpkgs 68688454720b2ea0df54ee9625739f7911fae000), but trying again made it work.
