Oliver Dunkl de91a42c6e Moves runHook to a later execution position
It moves runHook to a later position in the rcfile. After that we are
able to set the PS1 environment-variable for a nix-shell environment
e.g.:

  # turn the color of the prompt to blue
  shellHook = ''
    export PS1="\n\[\033[1;34m\][\u@\h:\w]$\[\033[0m\] ";
  '';

The DT_UNKNOWN fallback code was getting the type of the wrong path,
causing readDir to report "directory" as the type of every file.

Eelco Dolstra 27b7b94923 Set /nix/store permission to 1737
I.e., not readable to the nixbld group. This improves purity a bit for
non-chroot builds, because it prevents a builder from enumerating
store paths (i.e. it can only access paths it knows about).

Eelco Dolstra 128538ef06 nix-shell: Add --run flag
‘--run’ is like ‘--command’, except that it runs the command in a
non-interactive shell. This is important if you do things like:

  $ nix-shell --command make

Hitting Ctrl-C while make is running drops you into the interactive
Nix shell, which is probably not what you want. So you can now do

  $ nix-shell --run make

instead.

Eelco Dolstra b76589206a nix-shell: Interpret filenames relative to the #!-script
So you can have a script like:

  #! /usr/bin/env nix-shell
  #! nix-shell script.nix -i python

  import prettytable

  x = prettytable.PrettyTable(["Foo", "Bar"])
  for i in range(1, 10): x.add_row([i, i**2])
  print x

with a ‘script.nix’ in the same directory:

  with import <nixpkgs> {};

  runCommand "dummy" { buildInputs = [ python pythonPackages.prettytable ]; } ""

(Of course, in this particular case, using the ‘-p’ flag is more
convenient.)

Eelco Dolstra a957893b26 Allow nix-shell to be used as a #! interpreter
This allows scripts to fetch their own dependencies via nix-shell. For
instance, here is a Haskell script that, when executed, pulls in GHC
and the HTTP package:

  #! /usr/bin/env nix-shell
  #! nix-shell -i runghc -p haskellPackages.ghc haskellPackages.HTTP

  import Network.HTTP

  main = do
    resp <- Network.HTTP.simpleHTTP (getRequest "http://nixos.org/")
    body <- getResponseBody resp
    print (take 100 body)

Or a Perl script that pulls in Perl and some CPAN packages:

  #! /usr/bin/env nix-shell
  #! nix-shell -i perl -p perl perlPackages.HTMLTokeParserSimple perlPackages.LWP

  use HTML::TokeParser::Simple;

  my $p = HTML::TokeParser::Simple->new(url => 'http://nixos.org/');

  while (my $token = $p->get_tag("a")) {
      my $href = $token->get_attr("href");
      print "$href\n" if $href;
  }

Note that the options to nix-shell must be given on a separate line
that starts with the magic string ‘#! nix-shell’. This is because
‘env’ does not allow passing arguments to an interpreter directly.

aszlig 8b88d25cda libutil: Limit readLink() error to only overflows.
Let's not just improve the error message itself, but also the behaviour
to actually work around the ntfs-3g symlink bug. If the readlink() call
returns a smaller size than the stat() call, this really isn't a problem
even if the symlink target really has changed between the calls.

So if stat() reports the size for the absolute path, it's most likely
that the relative path is smaller and thus it should also work for file
system bugs as mentioned in 93002d69fc58c2b71e2dfad202139230c630c53a.

aszlig bbd45ac80f libutil: Improve errmsg on readLink size mismatch.
A message like "error: reading symbolic link `...' : Success" really is
quite confusing, so let's not indicate "success" but rather point out
the real issue.

We could also limit the check of this to just check for non-negative
values, but this would introduce a race condition between stat() and
readlink() if the link target changes between those two calls, thus
leading to a buffer overflow vulnerability.

Reported by @Ericson2314 on IRC. Happened due to a possible ntfs-3g bug
where a relative symlink returned the absolute path (st_)size in stat()
while readlink() returned the relative size.
