[Hackage] #661: optionally select the oldest available dependencies rather than the newest

#661: optionally select the oldest available dependencies rather than the newest ----------------------------+----------------------------------------------- Reporter: benmachine | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.6.0.3 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- When developing a package, you want to specify as wide a range of build- depends as possible, but it's often quite tedious to keep checking if your latest development effort hasn't made your package incompatible with some ancient version of a library you use. In view of this I think it would be helpful to have an option that asks cabal configure to pick the oldest possible version of each dependency, so you could quickly and easily ensure that at least the two endpoints are covered. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/661> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

cabal patch to improve "cabal update" behavior.
by Eyal Lotem 19 Apr '12

19 Apr '12

I built a preliminary prototype of "cabal update" enhancements: A) Using a Lazy I/O bytestring with the HTTP download, so that it can do a streaming-decompress on-the-fly (This gives a 30% speedup on my machine) B) Using the bytestring-progress library to show a useful progress report on the whole process. Unfortunately, due to the PVP, the version constraints are (as usual) over-restrictive, so they need to be relaxed. Until the fix is put on hackage, you have to install bytestring-progress from https://github.com/Peaker/bytestring-progress C) It's quick&dirty (Proof of concept), because: C.1) No version constraints on bytestring-progress C.2) Using hSetBuffering on stdout and ANSI terminal codes, which may be problematic in different kinds of terminals C.3) The only way to disable it is setting verbosity=quiet. It probably deserves its own option I hope it's a useful demonstration of the utility of this, though. It makes "cabal update" something I'd dread a little less to run :) Also, I was wondering why there's no monad for the passing of Verbosity around to so many functions. Then I could easily add more options that go around to control things like whether to show progress bars... Eyal

Move to github or other collaboration site
by Eyal Lotem 17 Apr '12

17 Apr '12

Hey, I am personally finding the process of contributing to cabal much more painful than it would be if it were on github. I think the project is losing on contributions, and that's a shame, for the following reasons: A) A contributor isn't certain his contribution will be accepted, and if it isn't, his effort is in vain. He may very well give up before starting. With github, worst-case he can maintain a hosted fork, and point people to it. B) Even if it is accepted, *until* it is, he has no easy way of pointing people to his fork, unlike on github. C) Making a pull request is much easier and less trouble than registering to a mailing list, and the overheads associated with communicating email patches. I think most collaborators will gladly spend hours improving cabal, but would rather not spend minutes on patch sending overheads. Please move development of cabal to github or at least a darcs-hosting site where it is easy to make hosted forks and send pull requests. Eyal
