potiuk opened a new pull request, #35685:
URL: https://github.com/apache/airflow/pull/35685
Flit allows to build reproducible packages (packages that can
be compared bit-by-bit) providing that source date epoch is
set to repeatable value when package is built. This PR implements
reproducibility of our builds by freezing the documentation
preparation time in provider.yaml as "source date epoch" and
always using it when building the package. This way anyone
using breeze to build the package will have exactly the same
binary package produced, which will make it way easier to
verify if the packages are ready for release by the PMC member.
We will no longer have to check the sources, PMC members will
simply need to build the same packages locally using breeze and
see if the generated packages are exactly the same.
Based on #35617 so it should only be merged after that one
