Hello everybody,
some time ago I helped adding some package in the repo, and was just starting to understand how to do this when Peter dropped maintaining the repo in favour of Magnus. Magnus introduced this new method with cblrepo, that (it seems to me) automate the updating process, so the group didn't need my work for updating "manually" the packages.
Unfortunately today pacman rejected to update my system because happstack-server now need an old version of a package already present. haskell-happstack-server: require haskell-hslogger=1.1.0 (in community there's 1.1.5)
Why the requiring a fixed version, when the cabal file doesn't? Is there a way to solve the problem without modifying manually the PKGBUILD? If I do modify the PKGBUILD manually how can I make this available to the repo?
It's safer to require a specific version since GHC underneath will code in a dependency on a hash of the version of hslogger used. The end result without strict dependencies would be that pacman allows an upgrade that GHC would reject at runtime, i.e. you end up with a broken system.
I also would like to help adding some more package, but I still don't know how to do this with cblrepo.
After installing cblrepo you would do the following to upgrade hslogger: 0. Update info about all packages that are available on Hackage: % cblrepo idxsync 1. Upgrade the hslogger package: % cblrepo addbasepkg hslogger,1.1.5 2. Bump all packages that use hslogger: % cblrepo bump hslogger 3. Create PKGBUILDs: % cblrepo pkgbuild $(cblrepo build hslogger) 4. Verify that all builds properly: % ./makeahpkg -x -l <dir-for-chroot> -- $(cblrepo build hslogger) 5. If the build succeeds then post the diff either to this list or directly to me. If you want to add packages you use `cblrepo add`. Help is built in, but if you get stuck feel free to send emails to this list or directly to me. /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus@therning.org jabber: magnus@therning.org twitter: magthe http://therning.org/magnus Perl is another example of filling a tiny, short-term need, and then being a real problem in the longer term. -- Alan Kay
