# parabola changes and rationale:
#
# Several Parabola packages depends on ICU, and the ICU soname changes often.
# This means that if we don't rebuild all the Parabola packages which depend
# on ICU, as soon as the new ArchLinux, ArchLinux32, and ArchLinuxARM ICU
# packages are synchronized into the Parabola repositories, we have a problem.
# The repo server synchronizes with the upstream repos un-attended; so this
# is a wonderful surprise each time; and we hustle frantucally to get the
# system sane again. We could watch the testing and staging repos of each
# upstream, and start re-building everything in a Parabola staging repo;
# but that could result in discarded work, if those exact versions are not the
# ones which are eventually released into [core].
#
# At first nothing was done to fix or workaround that issue. In practice,
# once a new ICU was synchronized, many users were upgrading before the
# Parabola packages had the time to be rebuilt. For such users, it
# broke all the installed Parabola packages that were depending on the old ICU.
# This means that users had to find a way to downgrade packages manually or wait
# until developers would finally have rebuilt all the packages that were broken.
#
# Then such packages were modified to make them depend on the exact version of
# the ICU packages they were built against. This way, once the new ICU package
# was synchronized, users could not upgrade if they had packages that were not
# rebuilt yet against the new ICU package. However this workaround also prevents
# installing packages that depends on the new ICU.
#
# The correct fix would probably be to automatically build all the Packages
# instead of relying on Arch Linux Packages. Still, a staging repo would be
# required to hold the new packages, until they all can be released together sanely.
# However we don't have the code, configuration and/or infrastructure to run
# an automatic builder for all packages yet even if there is work in this
# direction.
#
# In the meantime, this version of ICU is meant to enable Parabola packages to
# link against it at runtime. This enables all the Parabola packages to depend
# only on the ICU version, which is usually the upstream distribution's ICU but
# is occasionally this ICU if the Parabola package has not yet been rebuilt
# after an ICU update.
#
# It is inspired by the admittedly awkward hack of versioned library
# dependencies more commonly seen in e.g. the AUR as 'icu65' or somesuch which
# proprietary binaries built against Debian's ICU will depend on, but awkward
# is in the eyes of the beholder and this elegantly scales to Parabola's needs,
# without consuming increasing resources, which is the best definition of "not
# awkward".
#
# To use it, simply add the following dependency to any package which parabola
# has built or rebuilt:
#
# depends=('libicui18n.so')
#
# or whichever shared library is reported by readelf -d /path/to/compiled/ELF/file
# and, every time the upstream distribution upgrades ICU, update this package
# as well, to ensure it always stays exactly one version behind.
#
# This works well for ICU, even for packages which link to both the older and
# newer versions of libicu*.so, since ICU uses versioned symbols as reported by
#
# nm -D --demangle --with-symbol-versions /path/to/library
#
# However, caution must be taken before implementing the same idea for other
# libraries. So the idea is to only use it for libraries that often have this
# issue.
#
# Changes:
# - remove all files other than libicu*.so.*
# - depend on icu; this is needed because if the package is installed on its
# own, ldconfig will create untracked symlinks which were supposed to be
# installed by the icu package.
