I take that as a no.
So here is my analysis:
ghc-doc’s trigger runs haddock. Haddock requires libffi6. For some
reason, apt tries to run the trigger before all of ghc-haddock’s
dependencies are installed. Here are the relevant bits from the log at
http://aws-logs.debian.net/ftbfs-logs/2014/11/14/libghc-authenticate-doc_jessie_upgrade.log.gz
The following NEW packages will be installed:
libdevmapper1.02.1 libdns-export100 libexpat1 libfcgi-perl libffi6
The following packages will be upgraded:
ghc-haddock grep ifupdown initscripts iproute libapt-pkg4.12 libc-bin

Unfortunately
https://www.debian.org/doc/debian-policy/ch-relationships.html only
talks about configuring and running postinst, but not triggers,
Hence my question to those in the know (hence CC’ing debian-dpkg):
How do I make sure that ghc-doc’s trigger is not run until all of
ghc-doc’s dependencies (and their dependencies) are installed (not
necessarily configured).
The current chain of dependencies is:
Package: ghc-doc
Depends: haddock-interface-22, perl
Package: ghc-haddock
Provides: haddock, haddock-interface-21, haddock-interface-22
Depends: ghc (= 7.6.3-19), libc6 (>= 2.14), libffi6 (>= 3.0.4), libgmp10
(Alternatively, maybe ghc-doc’s trigger should simply fail less hard,
under the assumption that the final trigger run should work, and if not,
a broken documentation index is sever enough to abort an upgrade.)
Greetings,
Joachim
