#4148 closed enhancement (fixed)

Reproducible build date in generated SQL files

Reported by: myon Owned by: Algunenano
Priority: medium Milestone: PostGIS 2.5.0
Component: postgis Version: master
Keywords: Cc: Bas Couwenberg

Description

Next to BUILD_DATE in configure.ac (#4147), another source of build variation are the "Generated on" dates in the generated .sql files. The attached patch makes the scripts honor SOURCE_DATE_EPOCH when set in the build environment, and always uses UTC as timestamp (which configure.ac was already doing).

As these are mere comments in the generated files, another way to suppress the build variation would be to simply drop the timestamps. These carry next to no extra information to the BUILD_DATE information already contained in the very same files.
