# sources.nix contains information about which versions of some of our
|
|
# dependencies we should use. since we use it to pin nixpkgs and the PyPI
|
|
# package database, roughly all the rest of our dependencies are *also*
|
|
# pinned - indirectly.
|
|
#
|
|
# sources.nix is managed using a tool called `niv`. as an example, to
|
|
# update to the most recent version of nixpkgs from the 21.11 maintenance
|
|
# release, in the top-level tahoe-lafs checkout directory you run:
|
|
#
|
|
# niv update nixpkgs-21.11
|
|
#
|
|
# or, to update the PyPI package database -- which is necessary to make any
|
|
# newly released packages visible -- you likewise run:
|
|
#
|
|
# niv update pypi-deps-db
|
|
#
|
|
# niv also supports chosing a specific revision, following a different
|
|
# branch, etc. find complete documentation for the tool at
|
|
# https://github.com/nmattia/niv
