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 exists for Parabola packages to link against +# at runtime. In this way, Parabola packages can depend only on the "sodeps" exposed +# by ICU, which is usually provided by the upstream distribution's ICU; but may be +# this ICU, if the Parabola package has yet to be rebuilt agianst the upgraded ICU. +# +# It is inspired by the admittedly awkward hack of versioned library +# dependencies more commonly seen (e.g. in the AUR as 'icu65') on which +# proprietary binaries built against Debian's ICU will depend. It is awkward, +# 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. + + +_pkgname=icu +pkgname=${_pkgname}-compat +pkgver=67.1 # should always be one major version behind core/icu +pkgrel=1 +pkgrel+=.parabola1 +pkgdesc="International Components for Unicode library" +pkgdesc+=" (compatibility libraries for the previous release)" +arch=(x86_64) +arch+=(armv7h i686) +url="http://site.icu-project.org/home" +license=('custom:icu') +depends=('gcc-libs' 'sh') +depends+=("icu>$pkgver") # core/icu should always be one major version ahead +conflicts=("icu<=$pkgver") # core/icu should always be one major version ahead +makedepends=('python') +provides=(libicu{data,i18n,io,test,tu,uc}.so) +source=(https://github.com/unicode-org/icu/releases/download/release-${pkgver//./-}/${_pkgname}4c-${pkgver//./_}-src.tgz{,.asc}) +# https://github.com/unicode-org/icu/releases/download/release-65-1/SHASUM512.txt - no checksum file for v67 release +sha512sums=('4779f1ce1ca7976f6fad6768853ea8c540da54d11509e3b6cfd864a04b5f2db1c3d4b546387f91ad02fb90804525bc37d2543173f0d705d6ca11dc6f2b7640a8' + 'SKIP') +validpgpkeys=('BA90283A60D67BA0DD910A893932080F4FB419E3') # "Steven R.
