After a dev-lang/ghc update the automatically triggered rebuild of dev-haskell/* packages failed at dev-haskell/network because it DEPENDs (and RDEPENDS) on dev-haskell/parsec, which however was *not* rebuilt before network. I ran haskell-updater afterwards, which got the order right (maybe coincidentally?), but I'm surprised that portage didn't. Note that this happened last week with portage-2.1.x, before portage-2.2.1 went stable, so maybe it was fixed there (I didn't notice anything from skimming the portage-2.2.1 tracker). I originally wrote to gentoo-user (in case somebody could think of a reason why this isn't a bug), and am only now reporting it here due to a lack of replies. Reproducible: Didn't try Steps to Reproduce: 1. Upgrade dev-lang/ghc 2. 3. Actual Results: emerge fails (or might fail) at dev-haskell/network. Expected Results: emerge updates ghc and rebuilds all dependent dev-haskell packages successfully. % emerge --info Portage 2.2.1 (default/linux/amd64/13.0, gcc-4.6.3, glibc-2.15-r3, 3.10.7-gentoo

you need to build ghc with --complete-graph option otherwise emerge fails to set correct build order.
Sorry for the delay, I was away on holiday and forgot about this bug (plus, I expected more activity). (In reply to Alexander Vershilov from comment #1) > you need to build ghc with --complete-graph option otherwise emerge fails to > set correct build order. I would be surprised by that, since if that's true, portage only considers the immediate dependencies of the package when triggering a slot rebuild (there are only two levels of dependencies here: the immediate deps of ghc, and *their* inter-dependencies). Actually, I decided to look at the emerge(1) man page, and found this: " --rebuild-if-new-slot [ y | n ] Automatically rebuild or reinstall packages when slot/sub-slot := operator dependencies can be satisfied by a newer slot, so that older packages slots will become eligible for removal by the --depclean action as soon as possible. This option only affects packages that specify slot/sub-slot := dependencies which are supported beginning with EAPI 5. Since this option requires checking of reverse dependencies, it enables --complete-graph mode whenever a new slot is installed. This option is enabled by default." So the --complete-graph option should have been set. According to Zac's blog, this option existed in portage-2.1.11.1 (http://blogs.gentoo.org/zmedico/2012/06/23/automatic-rebuilds-with-experimental-eapi-4-slot-abi/). Maybe it didn't imply "--complete-graph" then?

Maybe it didn't imply "--complete-graph" > then? Yeah, very likely. We keep encountering minor portage bugs regarding to subslots. All of them are fixed in current portage. Anyways, h-u explicitely sets --complete-graph now: https://github.com/gentoo-haskell/haskell-updater/commit/ac39860327f4ab7f401ae9135bb18b85bbeaa324 In rare cases it won't be enough, like in bug #449094, or in cases where h-u will break more things that cure (due to upgrades deep down in dep chain). But at least ghc upgrade case should be handled correctly by now.
