darcs patch: Search for programs in bindir of user
by Martin Kiefel 07 Nov '10

07 Nov '10

Hi, I wrote this for #663. Unfortunately, I did not find an easy way to find out if a Program type is using the standard way of locating a program or if it uses a custom method for this (without breaking the signitures). So my solution tries to locate a program (no compilers) first in the directories of PATH and then falls back to the bindir that will be used to install the program later on. Not sure if this is the nicest way to do this, since program detection has to be split up in programs that are found the traditional way and others that are additionally search in the bindir. Cheers, Martin Sun Nov 7 15:13:12 CET 2010 Martin Kiefel <mk(a)nopw.de> * Search for programs in bindir of user See Ticket #663. If program is not found in the PATH directories it will be search in the local bindir, which was specified by the user.

Hi, here is the support for Distro releases. The release name "default", if used in the public API, is special to indicate "no release name", for distributions that doe not distinguish between releases. I’ll update the Wiki to reflect the new paths now.

#428: cabal update uses too much bandwidth --------------------------------+------------------------------------------- Reporter: claus | Type: defect Status: new | Priority: normal Milestone: cabal-install-0.8 | Component: cabal-install tool Version: 1.6.0.1 | Severity: normal Keywords: | Difficulty: hard (< 1 day) Ghcversion: 6.8.3 | Platform: --------------------------------+------------------------------------------- Comment(by claus): I just found another reason why this is annoying: when using `--remote- repo`, cabal requires `update`, and that will always re-download the huge hackage index as well as the tiny index for the remote repo. Not to mention that we still have to re-download the huge index every time we want to install a newly updloaded package. The compressed index has now grown to over 2MB! Given that hackage only adds, almost never removes packages, why not have checkpoints of the index every week, and daily tarballs with just the added-since-checkpoint .cabal` files? Then cabal could download just the dailies, starting from the last downloaded local checkpoint. Very little additional technology - just untar the dailies on top of the last checkpoint (if the repo doesn't support dailies, fall back to the current scheme; for hackage, one could either have a server-side script selecting the dailies, or even let cabal do that client-side - the former being more efficient, the latter placing fewer burdens on non-hackage repo providers). -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/428#comment:6> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

About building wx and Cabal
by Duncan Coutts 04 Nov '10

04 Nov '10

Jeremy, I've briefly been following your posts about building wx using Cabal (for the benefit of other cabal-devel readers the latest is:) http://wewantarock.wordpress.com/2010/11/03/building-a-shared-library-in-ca… I want to make sure we don't lose what the core problem is and I'd like to work out what the "right" solution would be in terms of extra Cabal features. Perhaps you can translate into a feature request ticket that says what the core problem is (e.g. is it simply that static linking does not work for this C lib etc). Without yet understanding all the details, my first impression is that this problem would fit well with a feature I've been imagining for defining "foreign library" sections in a .cabal file, as opposed to Haskell libraries. These could contain C,C++ code as normal, but would be built using the platform rules, rather than the Haskell compiler rules. I don't yet understand why you've got a constraint on using a shared library, but perhaps the thing to do is simply to allow foreign lib sections to state such a constraint, e.g. the point might be to make a shared lib for a plugin, so a static lib is not the goal. Otoh, if it's possible to both build a static and shared lib from the same description, that's probably a useful thing in many circumstances. Duncan

Can I persuade the cabal-install maintainer? I'm using the new darcs-2.5 Cheers Christian maeder@denebola:~/haskell> darcs get http://darcs.haskell.org/cabal-install/ Converting old-fashioned repository to hashed format... ******************************************************************************* Fetching a hashed repository would be faster. Perhaps you could persuade the maintainer to run darcs optimize --upgrade with darcs 2.4.0 or higher? *******************************************************************************
