# this script will generate versions.nix in the right location
# this should contain the versions' revs and hashes
# the stable revs are stored only for ease of skipping
# by default nix-prefetch-url uses XDG_RUNTIME_DIR as tmp
# which is /run/user/1000, which defaults to 10% of your RAM
# unless you have over 64GB of ram that'll be insufficient
# resulting in "tar: no space left on device" for packages3d
# hence:
export TMPDIR=/tmp
# if something goes unrepairably wrong, run 'update.sh all clean'
# TODO
# support parallel instances for each pname
# currently risks reusing old data
# no getting around manually checking if the build product works...
# if there is, default to commiting?
# won't work when running in parallel?
# remove items left in /nix/store?
# reuse hashes of already checked revs (to avoid redownloading testing's packages3d)
# nixpkgs' update.nix passes in UPDATE_NIX_PNAME to indicate which package is being updated
# assigning a default value to that as shellcheck doesn't like the use of unassigned variables
