#131: cabal-install should rebuild dependants when a package is upgraded ---------------------------------+------------------------------------------ Reporter: bringert | Owner: Type: defect | Status: new Priority: normal | Milestone: Cabal-2.0 Component: cabal-install tool | Version: HEAD Severity: normal | Resolution: Keywords: | Difficulty: hard (< 1 day) Ghcversion: 6.6 | Platform: Linux ---------------------------------+------------------------------------------ Comment (by guest): A real-life "war story" that seems to illustrate the problem, or at least be closely related: I used 'cabal upgrade' to upgrade a bunch of packages, in particular bytestring and various regex-*, since I wanted to install something that depended on them. Later, however, I tried to install Yi, which as it turns out was incompatible with the latest version of bytestring. I downgraded bytestring, but then had to rebuild vty (so it would be built with the older bytestring) and also unregister many of the newer versions of the regex-* packages, since Yi depended on them; with the newer versions installed, they were chosen to fulfill Yi's dependencies, but those newer versions depended on the newest version of bytestring, which was no longer installed. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/131#comment:3 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
