# Maintainer (Arch): Andreas Radke # Contributor (Arch): Art Gramlich # Contributor: Denis 'GNUtoo' Carikli # Contributor: Eli Schwartz # 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 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.
