cabal-db's Issues

Some bounds need revision

I am trying to reverse-engineer correct bounds for cabal-db master to build.

Seems we need:

optparse-applicative < 0.14
Cabal < 2
base < 4.9

I applied these upper bounds to all releases of cabal-db on hackage, e.g. https://hackage.haskell.org/package/cabal-db-0.1.12/revisions/
Older versions might need even tighter bounds, but I will not research the bounds for old versions. The bounds that make 0.1.12 compile will also prevent the resolver to find older version.

Works:

$ cabal build -w ghc-7.10.3 --constraint='Cabal < 2' --constraint='optparse-applicative < 0.14'

Wrong location of hackage.haskell.org/00-index.tar

On my mac, the hackage.haskell.org/00-index.tar file is not located in ~/.cabal/packages but in ~/Library/Haskell/repo-cach.
Not sure if it's due to that it's running on a mac, or because it's a cabal-install 1.17.0 snapshot.

 $ cabal-db info binary
cabal-db: /Users/kolmodin/.cabal/packages/hackage.haskell.org/00-index.tar: openBinaryFile: does not exist (No such file or directory)

 $ ls ~/.cabal
config      config.platform logs        setup-exe-cache

 $ ls -lah ~/Library/Haskell/repo-cache/hackage.haskell.org/00-index.tar
-rw-------  1 kolmodin  staff    88M Apr 22 10:44 /Users/kolmodin/Library/Haskell/repo-cache/hackage.haskell.org/00-index.tar

Reading the ~/.cabal/config gives some help in finding the tarball.

 $ grep remote-repo-cache .cabal/config

Doesn't work for packages that are not on Hackage?

I don't know how is cabal-db working, but as far as I can see it's not working for packages that are not on Hackage.

I have a library and executable that I develop using sandbox so every dependency is in the sandbox or in system-level dirs. Is there a way to make cabal-db working in this case? Would it be too hard to add this feature?

Not in scope: data constructor `AGPL'

It seems that your package is missing some CPP magic, or dependency version bounds:

(This is with Cabal-1.6)

cabal db didn't clean up

I interrupted cabal-db diff with Ctrl-C, and the source directories were not removed. (I hope they would have been removed if I didn't interrupt!) You probably have to add a bracket in the relevant place.

Also, it would be cleaner if the packages were unpacked not in the current directory, but in a temporary one.

No help for subcommands

% cabal-db diff --help

Compilation fails with tar version 0.3.2.0

I tried installing cabal-db but the compilation failed with the following (abbreviated) error message:

Src/Main.hs:94:32:
    `Tar.Entries' is applied to too many type arguments
    In the type signature for `listTar':
      listTar :: Show e => Tar.Entries e -> [([FilePath], ByteString)]

Turned out that the tar package was installed at version 0.3.2.0. Changing cabal-db.cabal to restrict the version of tar to 0.4, i.e., tar == 0.4.*, made the compilation complete successfully and the program now runs flawlessly.
