I think this makes sense, because now all the plugins will be gnome3 gtk3
based, the same way nm-applet is.
I also removed networkmanager_pptp_gnome variation of networkmanager_pptp
package, because i think no variation is needed and gnome support should
be on by default like in other packages.
Fixing this will require some fiddling due to the odd version number;
see the Hydra build logs for more.

This now provides a handful of different grsecurity kernels for slightly
different 'flavors' of packages. This doesn't change the grsecurity
module to use them just yet, however.

AppArmor only requires a few patches to the 3.2 and 3.4 kernels in order
to work properly (with the minor catch grsecurity -stable includes the
3.2 patches.) This adds them to the kernel builds by default, removes
features.apparmor (since it's always true) and makes it the default MAC
system.

fetchpatch is fetchurl that determinizes the patch.
Some parts of generated patches change from time to time, e.g. see #1983 and
http://comments.gmane.org/gmane.linux.distributions.nixos/12815
Using fetchpatch should prevent the hash from changing.

PyUSB is a Python module that wraps libusb 1.0. (It can wrap other USB
libraries too, but I've hardcoded it for libusb as it seems the most
appropriate.)
1) Packages formerly called haskell-haskell-platform-ghcXYZ-VVVV.X.Y.Z are
now called haskell-platform-VVVV.X.Y.Z. The latest version can be
installed by running "nix-env -i haskell-platform".
2) The attributes haskellPackages_ghcXYZ.haskellPlatform no longer exist.
Instead, we have attributes like haskellPlatformPackages."2012_4_0_0".
(The last numeric bit must be quoted when used in a Nix file, but not on
the command line to nix-env, nix-build, etc.) The latest Platform has a
top-level alias called simply haskellPlatform.
3) The haskellPackages_ghcXYZ package sets offer the latest version of every
library that GHC x.y.z can compile. For example, if 2.7 is the latest
version of QuickCheck and if GHC 7.0.4 can compile that version, then
haskellPackages_ghc704.QuickCheck refers to version 2.7.
4) All intermediate GHC releases were dropped from all-packages.nix to
simplify our configuration. What remains is a haskellPackages_ghcXYZ set
for the latest version of every major release branch, i.e. GHC 6.10.4,
6.12.3, 7.0.4, 7.2.2, 7.4.2, 7.6.3, 7.8.2, and 7.9.x (HEAD snapshot).
5) The ghcXYZPrefs functions in haskell-defaults.nix now inherit overrides
from newer to older compilers, i.e. an override configured for GHC 7.0.4
will automatically apply to GHC 6.12.3 and 6.10.4, too. This change has
reduced the redundancy in those configuration functions. The downside is
that overriding an attribute for only one particular GHC version has become
more difficult. In practice, this case doesn't occur much, though.
6) The 'cabal' builder has a brand-new argument called 'extension'. That
function is "self : super : {}" by default and users can override it to
mess with the attribute set passed to cabal.mkDerivation. An example use
would be the definition of darcs in all-packages.nix:
| darcs = haskellPackages.darcs.override {
| cabal = haskellPackages.cabal.override {
| extension = self : super : {
| isLibrary = false;
| configureFlags = "-f-library " + super.configureFlags or "";
| };
| };
| };
In this case, extension disables building the library part of the package
to give us an executable-only version that has no dependencies on GHC or
any other Haskell packages.
The 'self' argument refers to the final version of the attribute set and
'super' refers to the original attribute set.
Note that ...
- Haskell Platform packages always provide the Haddock binary that came with
the compiler.
- Haskell Platform 2009.2.0.2 is broken because of build failures in cgi and
cabal-install.
- Haskell Platform 2010.1.0.0 is broken becasue of build failures in cgi.
Now that both self and super are available to prefFun, we can use self, where appropriate to access late bound versions of most
packages.
When extensions are not used, there is no difference between self and super.
The existing knot-tying code I felt was a bit incoherent with result, finalReturn, self, refering to different various forms of the "haskellPackages" value and often
different forms in the same place.
This commit instills some object-oriented discipline to the construction of hasekllPackages using a small number of fundamental OO concepts:
* An class is a open recursive function of the form (self : fooBody) where fooBody is a set.
* An instance of a class is the fixed point of the class.
This value is sometimes refered to as an object and the values in the resulting set are sometimes refered to as methods.
* A class, foo = self : fooBody, can be extended by an extension which is a function bar = (self : super : barBody) where barBody a set of overrides for fooBody.
The result of a class extension is a new class whose value is self : foo self // bar self (foo self).
The super parameter gives access to the original methods that barBody may be overriding.
This commit turns the haskell-packages value into a "class".
The knot-tying, a.k.a the object instanitation, is moved into haskells-defaults. The "finalReturn" is no longer needed and is eliminated from the body of
haskell-packages. All the work done by prefFun is moved to haskell-defaults, so that parameter is eliminated form haskell-packages. Notice that the old prefFun took
two pameters named "self" and "super", but both parameters got passed the same value "result". There seems to have been some confusion in the old code.
Inside haskell-defaults, the haskell-packages class is extended twice before instantiation. The first extension is done using prefFun argument.
The second extension is done the extension argument, which is a renamed version of extraPrefs.
This two stage approach means that extension's super gets access to the post "perfFun" object while previously the extraPrefs only had access to the pre "prefFun"
object. Also the extension function has access to both the super (post "perfFun") object and to self, the final object. With extraPrefs, one needed to use the
"finalReturn" of the haskell packages to get access to the final object. Due to significant changes in semantics, I thought it best to replace extraPrefs with
extension so that people using extraPrefs know to update thier cod.
Lastly, all the Prefs functions have renamed the "self" parameter to "super". This is because "self" was never actually a self-reference in the object oriented sense
of the word. For example
Cabal_1_18_1_3 = self.Cabal_1_18_1_3.override { deepseq = self.deepseq_1_3_0_2; };
doesn't actually make sense from an object oriented standpoint because, barring further method overriding, the value of Cabal_1_18_1_3 would be trying to override it's
own value which simply causes a loop exception. Thankfully all these uses of self were really uses of super:
Cabal_1_18_1_3 = super.Cabal_1_18_1_3.override { deepseq = super.deepseq_1_3_0_2; };
In this notation the overriden Cabal_1_18_1_3 method calls the Cabal_1_18_1_3 of the super-class, which is a well-founded notion.
Below is an example use of using "extension" parameter
{
packageOverrides = pkgs : {
testHaskellPackages = pkgs.haskellPackages.override {
extension = self : super : {
transformers_0_4_1_0 = self.cabal.mkDerivation (pkgs: {
pname = "transformers";
version = "0.4.1.0";
sha256 = "0jlnz86f87jndv4sifg1zpv5b2g2cxy1x2575x727az6vyaarwwg";
meta = {
description = "Concrete functor and monad transformers";
license = pkgs.stdenv.lib.licenses.bsd3;
platforms = pkgs.ghc.meta.platforms;
maintainers = [ pkgs.stdenv.lib.maintainers.andres ];
};
});
transformers = self.transformers_0_4_1_0;
lensFamilyCore = super.lensFamilyCore.override { transformers = self.transformers_0_3_0_0; };
};
};
};
}
Notice the use of self in the body of the override of the transformers method which references the newly defined transformers_0_4_1_0 method.
With the previous code, one would have to instead akwardly write
transformers = super.finalReturn.transformers_0_4_1_0;
or use a rec clause, which would prevent futher overriding of transformers_0_4_1_0.
This should make it easier to enable proprietary pepper API plugins
though nixpkgs config, so it can be easily installed using something
like:
nix-env -i chromium-stable
With something like:
{ chromium.enablePepperFlash = true; }
In ~/.nixpkgs/config.nix to enable pepper API based Flash and to avoid
the browser wrapper from Firefox entirely.

This is a small wrapper around fetchzip. It allows you to say:
src = fetchGitHub {
owner = "NixOS";
repo = "nix";
rev = "924e19341a5ee488634bc9ce1ea9758ac496afc3"; # or a tag
sha256 = "1ld1jc26wy0smkg63chvdzsppfw6zy1ykf3mmc50hkx397wcbl09";
};
This function downloads and unpacks a file in one fixed-output
derivation. This is primarily useful for dynamically generated zip
files, such as GitHub's /archive URLs, where the unpacked content of
the zip file doesn't change, but the zip file itself may (e.g. due to
minor changes in the compression algorithm, or changes in timestamps).
Fetchzip is implemented by extending fetchurl with a "postFetch" hook
that is executed after the file has been downloaded. This hook can
thus perform arbitrary checks or transformations on the downloaded
file.
COPRTHR is a very excellent little SDK implementing OpenCL and related
tech for regular multicore processors, as well as things like my new
Parallella (along with remote/networked OpenCL compute support).

This hook allows to scatter files in $out to multiple outputs.
For "bin" and "doc" outputs there are prefefined default masks, but
they can be overriden by setting files_<outname>, for example:
files_bin = [ "/bin/*" "/lib/libexec/" ];
To make an effect hook must be specified in buildInputs.
allows to write neat expressions like (as we're still generating an
expression string):
```
{
build = haskellPackages.buildLocalCabalWithArgs {
inherit src name;
cabalDrvArgs = {
jailbreak = false;
doCheck = false;
};
};
}
```
without resorting to weird kung-fu like darcs does:
```
darcs = haskellPackages.darcs.override {
# A variant of the Darcs derivation that containts only the
# executable and
# thus has no dependencies on other Haskell packages.
cabal = { mkDerivation = x: rec { final = haskellPackages.cabal.mkDerivation (self: (x final) // {
isLibrary = false;
configureFlags = "-f-library"; }); }.final;
};
};
```
While here, move the `jailbreak = true;` as the default `cabalDrvArgs`
option.
The whole notion of per-compiler HP-compliant environments has failed
anyway and I'll try to get rid of that ASAP, so it feels pointless to
configure that stuff for GHC 7.8.2 to begin with.
