#246: cabal-install's tar unpacking does not cope well with links ----------------------------------+----------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: 6.8.2 Platform: | ----------------------------------+----------------------------------------- {{{ Extracting /home/me/.cabal/packages/hackage.haskell.org/pandoc/0.46/pandoc-0.46.tar.gz to /tmp/TMPpandoc-0.46... cabal: /tmp/TMPpandoc-0.46/pandoc-0.46/COPYRIGHT: copyFile: does not exist (No such file or directory) }}} If we look at this tarfile we find that the `COPYRIGHT` entry in the tar file is actually a symbolic link to `debian/copyright`. The tar code in `cabal-install` is designed to cope with symbolic links. It handles them by copying the target file. Same goes for hard links. The problem in this case is that it is trying to copy the other file before it has been unpacked. One partial solution would be to accumulate a list of links and then copy all at the end after the other files have been unpacked. It's only partial because someone could make a tarball with links pointing to other links. We can probably just ignore that problem and let it fail in the same way it does now. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/246> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

Cabal bugs
by Neil Mitchell 08 Mar '08

08 Mar '08

Hi, Using cabal and cabal-install from yesterday: D:\sources\contrib\google-chart>cabal install --hugs cabal: user error (Pattern match failure in do expression at Hackage/Install.hs: 99:6-19) D:\sources\contrib\google-chart>runhaskell Setup configure --hugs Configuring GoogleChart-0.2... Setup: The following installed packages are broken because other packages they depend on are missing. These broken packages must be rebuilt before they can be used. Two separate errors, one in cabal, one in cabal-install. The cabal error should at least tell me which packages are missing. Thanks Neil

darcs patch: Implement CLI flag --root-cmd for 'cabal install' as in #202 (+ 1 more)
by Andrea Vezzosi 06 Mar '08

06 Mar '08

Wed Mar 5 23:02:31 CET 2008 Andrea Vezzosi <sanzhiyan(a)gmail.com> * Implement CLI flag --root-cmd for 'cabal install' as in #202 It also adds the internal flag --only so we can avoid building a setup when build-type == Simple. This second patch (which is needed for the first) is for cabal: Wed Mar 5 22:44:43 CET 2008 Andrea Vezzosi <sanzhiyan(a)gmail.com> * Extend setupWrapper with setupWrapperEx so it can use an external program to gain privileges. This is needed to implement --root-cmd in cabal install.

[Hackage] #256: Copying files during installation is oblivious to ~

#256: Copying files during installation is oblivious to ~ ----------------------------------+----------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: low | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: 6.8.2 Platform: | ----------------------------------+----------------------------------------- I tried to install a cabal package into my home directory using {{{--prefix=~/local}}}. Cabal does not expand this to my home directory. This is very confusing, as all the files wind up in a directory called ~. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/256> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
