Bug#366184: libghc6-c2hs-dev: should pre-depend on ghc6

Well I procrastinating as it meant reading policy again and the package was removed anyway. :-) So because ghc6 is being upgraded /usr/bin/ghc-pkg is not available and the prerm script of libghc6-c2hs-dev fails. This can be fixed by calling /usr/lib/ghc-6.4.1/bin/ghc-pkg or calling /usr/bin/ghc-pkg6 in the prerm script. So the bug has been found. As libghc6-c2hs-dev is not available in unstable anymore I am closing this bug. Sounds good. I assume that the same issue would arise for any Debian package containing a GHC package, right? If so, I guess this should be advertised as the correct way to register/deregister GHC packages. I have downloaded all the source packages which build ghc packages [1] and looked at their postinst and prerm scripts and they are al doing fine. Most use dh_haskell anyway which generates correct postinst and prerm code as well.

Forgive my delay On Fri, Jun 23, 2006 at 08:29:17PM +0200, Arjan Oosting wrote: This does not seem to be a bug in libghc6-c2hs-dev. When the postinst script of libghc6-c2hs-dev is called, all the Depends should already be configured and ghc-pkg should be available. I looked more closely at the logs I have. (I don't have the screen output, but thankfully there is now dpkg.log.) Actually, even my initial bug report had a clue I missed. It is not the postinst of libghc6-c2hs-dev that failed, it is the prerm. Here are the relevant excerpts of dpkg.log: 2006-05-05 14:51:42 upgrade ghc6 6.4.1-2 6.4.1-2.1 2006-05-05 14:51:42 status half-configured ghc6 6.4.1-2 2006-05-05 14:51:44 status unpacked ghc6 6.4.1-2 2006-05-05 14:51:44 status half-installed ghc6 6.4.1-2 2006-05-05 14:51:46 status half-installed ghc6 6.4.1-2 2006-05-05 14:51:48 status unpacked ghc6 6.4.1-2.1 2006-05-05 14:51:48 status unpacked ghc6 6.4.1-2.1 ... 2006-05-05 14:52:17 upgrade libghc6-c2hs-dev 0.13.6-4 0.13.6-4.1 2006-05-05 14:52:17 status half-configured libghc6-c2hs-dev 0.13.6-4 ... 2006-05-05 14:54:48 status unpacked ghc6 6.4.1-2.1 2006-05-05 14:54:48 status half-configured ghc6 6.4.1-2.1 2006-05-05 14:54:49 status installed ghc6 6.4.1-2.1 So the sequence was - ghc6.prerm, removing the ghc-pkg alternative. - unpack the new ghc6 - libghc6-c2hs-dev.prerm, failing to ghc-pkg unregister - ghc6.postinst, reinstalling the ghc-pkg alternative There were a few related packages involved, c2hs, ghc6-prof, ghc6-libsrc, but I don't think they matter. You probably encountered some circular dependency during your upgrade which was broken somewhere by apt and caused this. Maybe you have more information about the upgrade, so we can reassign the bug to the right package? Otherwise I will close the bug. I will append the aptitude log for this run so you can inspect the full graph. I don't know off hand how to tell if there was a circular dependency, but I don't think there was one involving ghc and c2hs.

Bug#366184: libghc6-c2hs-dev: should pre-depend on ghc6
I can reproduce this problem. I used packages from snapshot.debian.net: http://snapshot.debian.net/archive/2006/03/27/debian/pool/main/g/ghc6/ghc6_6.4.1-2_i386.deb http://snapshot.debian.net/archive/2006/03/27/debian/pool/main/g/ghc6/ghc6_6.4.1-2.1_i386.deb http://snapshot.debian.net/archive/2006/04/17/debian/pool/main/c/c2hs/libghc6-c2hs-dev_0.13.6-4_i386.deb http://snapshot.debian.net/archive/2006/04/17/debian/pool/main/c/c2hs/libghc6-c2hs-dev_0.13.6-4.1_i386.deb The first step is downgrading to ghc6_6.4.1-2 and libghc6-c2hs-dev_0.13.6-4. The latter seems quite broken; I had to create a symlink ln -s /usr/lib/libghc6-c2hs-dev /usr/lib/c2hs-0.13.6 to convince it to install. I also got a warning from ghc-pkg (can't find GHCi lib c2hs.o), but it doesn't seem relevant. Anyhow, once I had those two versions installed, I tried to upgrade: # dpkg --install ghc6_6.4.1-2.1_i386.deb libghc6-c2hs-dev_0.13.6-4.1_i386.deb (Reading database ... 102699 files and directories currently installed.)

My dpkg is 1.13.21. By the way, if I reverse the order of the packages on the dpkg --install line, it works fine because dpkg deconfigures libghc6-c2hs-dev first. So it is currently a problem for a package to assume that a Depended-upon package will be configured during prerm. I note that the policy excerpt already cited in this bug is ambiguous: The Depends field should also be used if the postinst, prerm or postrm scripts require the package to be present in order to run. Note, however, that the postrm cannot rely on any non-essential packages to be present during the purge phase. It isn't clear whether present means configured. Another excerpt from the same section: A Depends field takes effect _only_ when a package is to be configured. It isn't clear whether configured means (de)configured.

When the postinst script of libghc6-c2hs-dev is called, all the Depends should already be configured and ghc-pkg should be available. You probably encountered some circular dependency during your upgrade which was broken somewhere by apt and caused this. Maybe you have more information about the upgrade, so we can reassign the bug to the right package? Otherwise I will close the bug.
