sdist drops executable permissions for files in the tarball

[draconx]

After upgrading to Cabal 1.8, running './Setup.lhs sdist' in any package is generating tarballs with bizarre permissions:

• Every directory has mode 0755.
• Every file has mode 0600.

In particular, the executable bits from files are lost, and files should be group/world readable. Cabal 1.6 generates correct permissions.

As an temporary workaround use cabal sdist rather than runghc Setup sdist.

'cabal sdist' solves the group/world readability problem, but executable bits are still lost.

Note also that cabal unpack does not preserve any executable permissions.

  * Preserve executable permissions on unpack

Will be included in next Cabal-1.10.x release, and next cabal-install-0.10 release.

The new behaviour is as follows:

• every directory has mode 0755
• files in extra-source-files that have the user executable bit set get mode 0755
• all other files get mode 0644
