# This expression will, as efficiently as possible, dump a
|
|
# *superset* of all attrpaths of derivations which might be
|
|
# part of a release on *any* platform.
|
|
#
|
|
# This expression runs single-threaded under all current Nix
|
|
# implementations, but much faster and with much less memory
|
|
# used than ./outpaths.nix itself.
|
|
#
|
|
# Once you have the list of attrnames you can split it up into
|
|
# $NUM_CORES batches and evaluate the outpaths separately for each
|
|
# batch, in parallel.
|
|
#
|
|
# To dump the attrnames:
|
|
#
|
|
# nix-instantiate --eval --strict --json ci/eval/attrpaths.nix -A names
|
|
