Subject: [PATCH] build/gen.py: Make LAST_COMMIT_POSITION reproducible
|
|
|
|
Abbreviated hashes can vary in length depending on the number of objects
|
|
in the Git repository. This frequently breaks reproducibility for distro
|
|
packages. Address this by adding --abbrev=12 to the 'git describe' call.
