Valentin Rothberg aa28dbbf88 analyse package sizes ... Analyse the size of all go-packages used during the build process via the newly added `hack/analyses/go-archive-analysis.sh` script. The script expects the `WORK` environment variable to be set, which points to a temporary work directory generated by `go build`. To generate such a work directory, set the `BUILDFLAGS="-work -a"`: * `-work` for creating the work directory * `-a` to force rebuilding all packages even when already cached The workflow may look as follows: ``` $ BUILDFLAGS="-work -a" make podman [...] WORK=/tmp/go-build127001249 $ WORK=/tmp/go-build127001249 ./hack/analyses/go-archive-analysis.sh ``` The output of the script has the format `$SIZE $PACKAGE` where $SIZE is the size of the compiled version of the go package (i.e., `.a` file) and $PACKAGE for the corresponding package, for instance, `math/big` for a stdlib package or vendor/... for vendored packages.
