Hi,
In Tumbleweed, we have libz-ng-compat1 which can be a drop-in replacement of libz1. The problem is zypper drop the previous package, before installing the new one, but the lib is required to extract the new RPM. Any idea how to solve this problem in the spec file?

The following NEW package is going to be installed: libz-ng-compat1
The following package is going to be REMOVED: libz1
This is great ..however atm it is not a drop-in replacement.. on my development system...
The following 2 NEW packages are going to be installed: libz-ng-compat1 zlib-ng-compat-devel
The following 7 packages are going to be REMOVED: fontconfig-devel freetype2-devel gd-devel libpng16-compat-devel libpng16-devel libz1 zlib-devel
All those packages think they need zlib pkgconfig and are therefore uninstalled..now.. do they need zlib-devel ?..NO.. It is just a bunch of long standing , bloat-generating bugs. The most notorious one being pkgconfig still injecting Requires.private as hard dependencies even when there are no static libraries around. The result is that none of the above packages really need zlib headers around but it is installed anyway.
Hi,
I reply to myself since I found a solution/workaround to install zlib-ng in place of zlib, without breaking the system (yes, zypper requires a libz installed), using the technology preview ZYPP_SINGLE_RPMTRANS which enables alternative and !!!experimental!!! commit strategy where all rpm operations are executed in a single rpm transaction.
To switch to libz-ng-compat1, I used: sudo env ZYPP_SINGLE_RPMTRANS=1 zypper install libz-ng-compat1
To go back to the default libz1, I used: sudo env ZYPP_SINGLE_RPMTRANS=1 zypper install libz1
If someone has another solution to get it working with a regular zypper call, please let me know.
Cheers, Guillaume
