# WARNING: Please read on bumping or applying patches!
#
# There are two circular dependencies to be aware of:
# 1)
# if we're bootstrapping configure and makefiles:
# libxcrypt -> automake -> perl -> libxcrypt
#
# mitigation:
# toolchain@ manually runs `make dist` after running autoconf + `./configure`
# and the ebuild uses that.
# (Don't include the pre-generated Perl artefacts.)
#
# solution for future:
# Upstream are working on producing `make dist` tarballs.
# https://github.com/besser82/libxcrypt/issues/134#issuecomment-871833573
#
# 2)
# configure *unconditionally* needs Perl at build time to generate
# a list of enabled algorithms based on the set passed to `configure`:
# libxcrypt -> perl -> libxcrypt
#
# mitigation:
# None at the moment.
#
# solution for future:
# Not possible right now. Upstream intend on depending on Perl for further
# configuration options.
# https://github.com/besser82/libxcrypt/issues/134#issuecomment-871833573
#
# Therefore, on changes (inc. bumps):
# * You must check whether upstream have started providing tarballs with bootstrapped
# auto{conf,make};
#
# * diff the build system changes!
