[Nix-dev] Testing Nginx public entry points with NixOps/libvirtd

[Daniel Hlynskyi]

Hello all NixOps users. I'd like to build my production system with
libvirtd backend, but I'm stopped with a problem. SSL certificates can't be
obtained in virtualized environment.

{
   services.nginx.virtualHosts."example.domain" = {
 enableSSL = true;
 enableACME = true;
   };
}

As far as I understand, letsencrypt tries to verify "example.domain", but
it points to production system, not to virtualized.

What are my options to fix this issue? In the end I'd like to add virtual
server to VPN and test public entry points from developer machine.

Re: [Nix-dev] pypi2nix: generate full PYTHONPATH from requirements?

[Daniel Hlynskyi]

pypi2nix supports `python.withPackages`. But how should I use the created
"environment" in NixOS service?

path = [ python-env ];

doesn't work

[Nix-dev] pypi2nix: generate full PYTHONPATH from requirements?

[Daniel Hlynskyi]

I'm trying to use pypi2nix-generated expression to create Kallithea
service.

 systemd.services.kalithea = {
  after = [ "network.target" ];
  wantedBy = [ "multi-user.target" ];
  script =
  let ppath =
concatMapStringsSep ":" (x:
"${x}/${python.interpreter.python.sitePackages}") (let self =
python.packages; in [
  # package
  self."Kallithea"
  # deps
  self."Babel"
  self."Beaker"
  self."FormEncode"
  self."Mako"
  self."Markdown"
  self."Pygments"
  self."Pylons"
  self."Routes"
  self."SQLAlchemy"
  self."URLObject"
  self."WebHelpers"
  self."WebOb"
  self."WebTest"
  self."Whoosh"
  self."celery"
  self."docutils"
  self."dulwich"
  self."mercurial"
  self."mock"
  self."py-bcrypt"
  self."python-dateutil"
  self."waitress"
  # second level deps
  self."MarkupSafe"
  self."funcsigs"
  self."pbr"
  self."six"
  # TODO: add all the others
]);
  in ''
export PYTHONPATH=${ppath}
${pythonPackages.pasteScript}/bin/paster serve
${kallithea1}/etc/development.ini;
  '';
};

So I need to feed PYTHONPATH into service, but I don't know a nice way to
recursively aggregate all the propagatedBuildInputs from Kallithea into
full PYTHONPATH
(and service wants all of them, as far as I understand)

So, is there a way to do this? I'm pretty new to Python infrastructure and
perhaps miss some obvious thing.

PS. Pinging my previous ask about PERL5LIB, which is an example of exact
this problem, but with Perl.

Such a module is welcome. I can share my configuration for debloating

btw, now I see there are duplicate entities, so I guess it is useful to
clean roots before nix-shell run.

I hope there is a way to pin src as GC root, but dumb `buildInputs = [
nixpkgsSrc ];` doesn't work.

Re: [Nix-dev] nix-shell and persistent environment

[Daniel Hlynskyi]

To complete previous answer.

I create a separate directory .nix-gc-roots, because nix-shell produces
many roots. Also, I haven't found yet a way to get nix root for nixpkgs
imported as external derivation, so after garbage collect I still have to
redownload some sources

Re: [Nix-dev] Setuid wrapper for bash script

Actually, I found a way to do what I need without setuid and sudoers, just
polkit rules

let

#!${pkgs.bash}/bin/bash
[[ -z "$1" ]] && echo Specify operation: start, stop, restart, status
&& exit 0
systemctl "$1" defenders.service
  '';

  allowService = service: group: ''
polkit.addRule(function(action, subject) {
  if (action.id == "org.freedesktop.systemd1.manage-units") {
if (action.lookup("unit") == "${service}.service"
  && subject.isInGroup("${group}")) {
var verb = action.lookup("verb");
if (verb == "start" || verb == "stop" || verb == "restart" ||
verb == "status") {
return polkit.Result.YES;
}
}
  }
});
  '';

in {
  users.groups.defenders_grp = { };

  environment.systemPackages = [
restartScript
  ];

  security.polkit.extraConfig = ''
${allowService "defenders" "defenders_grp"}
  '';
}

[Nix-dev] Setuid wrapper for bash script

[Daniel Hlynskyi]

Hi. I want to allow some user to restart systemd service. I found that
setuid wrappers should be used for this task. Here is what I've written:

  environment.systemPackages = [
(pkgs.writeScriptBin "restart-defenders" ''
#!${pkgs.bash}/bin/bash
systemctl restart defenders.service
 '')
  ];

  security.setuidPrograms = [ "restart-defenders" ];

File was created

# ls -la /var/setuid-wrappers/restart-defenders
-r-s--x--x 1 root root 12856 Sep 14 17:17
/var/setuid-wrappers/restart-defenders

But when running as normal user I get

$ restart-defenders
 AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ===
Authentication is required to restart 'defenders.service'.
Multiple identities can be used for authentication:
 1.  System administrator (root)
 2: ...

What am I doing wrong?

Re: [Nix-dev] NixOps usage survey.

[Daniel Hlynskyi]

I am switching manual deployment to NixOps, and I'm getting lots of quirks
in hetzner, virtualbox, libvirtd and container backends.

Also, because of impurities in my systems, I can't switch easy from
production to, for example, virtualbox deployment.

So no success story here, but I like this tool and hope to improve it.

Re: [Nix-dev] typed nix

[Daniel Hlynskyi]

Dynamic attributes make exact typing hard. Perhaps Nix will adopt the
gradually typed approach in a future.

But would that be worth of it?

Re: [Nix-dev] Including "beta" or "unstable" identifiers in package names?

[Daniel Hlynskyi]

Another solution is to abandon parsing of derivation name and include
"meta" to derivation. Then the name and version representations can be
included as meta.name and meta.version in whichever format is liked by
maintainer.

mkDerivation can do name = "${meta.name}-${meta.version}" itself.

Meta should be saved in DB or .drv files.

How much should be done in Nix to allow this?

[Nix-dev] Override virtualbox

[Daniel Hlynskyi]

I know about nixpkgs.config.packageOverrides, but I cannot override
virtualbox with it. Given

nixpkgs.config.packageOverrides = sup_: {
  linuxPackages.virtualbox =
sup_.linuxPackages.virtualbox.override { headless = true; };
};
virtualisation.virtualbox.host.enable = true;

I get error in nixops deploy:

  error: attribute ‘kernel’ missing, at
/home/danbst/nixpkgs/nixos/modules/services/logging/klogd.nix:12:42
  (use ‘--show-trace’ to show detailed location information)

Without override it evaluates OK.

Re: [Nix-dev] changing the default source epoch to be zip-safe

[Daniel Hlynskyi]

still, why 1.1.1970? One of @edolstra's commits introduced algorithm, that
sets source epoch time to most recent source change date. Wouldn't that be
better date for /nix/store? Currently datetime in /nix/store carries zero
information.

Also, I'd like to notice that non-epoch-starttime files do exist in my

Re: [Nix-dev] How to install specific version of a package?

[Daniel Hlynskyi]

Nix allows you to have multiple versions of one package, but each version
can require it's specific build recipe.

nixpkgs - is a place for latest versions of packages, and, pragmatically,
for most used non-latest versions. The place for all packages of all
versions is currently vacant.

Given this, I can think of several ways to get non-latest version of
package in Nix:

- already mentioned install from binary cache
- install from specific checkout of nixpkgs (
http://edwtjo.me/posts/2016-04-24-installing-older-pkgs-in-nixos/ and
https://www.reddit.com/r/NixOS/comments/4itnth/installing_older_pkgs_in_nixos/d328l1v
)
- install from overriden expression. This is the most unstable way, because
many packages do require changes to recipe. But for certain simple kinds of
packages it can be automated.

Given the following oldversion.nix:

{ pkg, version }:
let
  pkgs = import  {};
  inherit (builtins) trace;
  inherit (pkgs) lib;
  traceSeq = x: y: trace (builtins.deepSeq x x) y;
  oldversion = package: version:
let getVersion = name: lib.last (lib.splitString "-" name);
in package.overrideDerivation (super: {
  name = super.name + "-oldversion-" + version;
  inherit version;
  src =
let upstreamUrls = super.src.urls;
patchedUrls = map (x: builtins.replaceStrings [(getVersion
super.name)] [version] x) upstreamUrls;
in pkgs.fetchurl { urls = patchedUrls; sha256 = null; sha512 =
null; md5 = null; sha1 = null; };
});
in oldversion pkg version

you can install different versions of same package with the following
monstruous command:

danbst@iron ~/oldversion$
$ nix-env -f oldversion.nix --arg pkg "with import {}; siege"
--argstr version "3.0.3" --install
replacing old ‘siege-3.0.8-oldversion-3.0.3’
installing ‘siege-3.0.8-oldversion-3.0.3’

danbst@iron ~/oldversion$
$ nix-env -f oldversion.nix --arg pkg "with import {}; siege"
--argstr version "4.0.2" --install
replacing old ‘siege-3.0.8-oldversion-3.0.3’
installing ‘siege-3.0.8-oldversion-4.0.2’

Re: [Nix-dev] Nix GUI? / make Nix more beginner-friendly

[Daniel Hlynskyi]

Hey Roland, can you tell which package manager GUI do you like best?

I'm addicted to command line interface because
- want to do nix-instantiate, nixos-rebuild, nix-build and nix-shell.
Nix-env -i is the rarest of my tools
- it works even If X is unavailable (remote, broken X)
That's also a reason why I hardly will use GUI variant.

But I agree that some graphical Nix Explorer would be better than nix-store
--query and nix-env --query.

Re: [Nix-dev] multiple versions of the same software? / collisions

[Daniel Hlynskyi]

I can be mistaken, but nix-env dash-splits name to get name without
version, and uses it to upgrade or sideinstall into environment. This works
bad for python, because python34 and python35 are separate expressions,
treated as one in nix-env.

You can override the name of package in .nixpkgs/config.nix for a
workaround, but i guess you want nix-shell in this case.

Re: [Nix-dev] duplicate packages?

[Daniel Hlynskyi]

Have you run sudo nix-collect-garbage -d ? Even If yes, you still have to
check all gc roots to belong to system, and not to side nix-builds

Re: [Nix-dev] PERL5LIB and lib.makePerlPath

[Daniel Hlynskyi]

So, I found a hackish solution. Just create a new derivation with PERL5LIB
as it's output

# perl5lib.nix
packages:
  let pkgs = import  {};
in builtins.readFile (builtins.toString (pkgs.stdenv.mkDerivation {
  name = "PERL5LIB";
  buildInputs = [pkgs.perl] ++ packages;
  buildCommand = "echo $PERL5LIB > $out";
}))

$ nix-instantiate --read-write-mode --eval -E 'with import {};
(import ./perl5lib.nix) [perlPackages.DBDPg]'
"/nix/store/...-perl-5.22.1/lib/perl5/site_perl:/nix/store/...-perl-DBD-Pg-3.5.3/lib/perl5/site_perl:/nix/store/...-perl-DBI-1.634/lib/perl5/site_perl\n"

Re: [Nix-dev] Project environment setup

[Daniel Hlynskyi]

Looks like gradle25 package doesn't follow nixpkgs conventions here. It has
no `.override` attribute, which, as I remember, is added by `callPackage`
function.
I think this is a bug, but there is a workaround:

```
# shell.nix

{ pkgs ? import  {} }:
let
  mygradle = (pkgs.gradleGen.override {
jdk = pkgs.openjdk8;
  }).gradle25;
in pkgs.stdenv.mkDerivation {
name = "myproject";
buildInputs = [ mygradle ];
}
```

You didn't want `.overrideDerivation` here, I think, just `.override`.

Re: [Nix-dev] evalModules: how to use it?

[Daniel Hlynskyi]

Unfortunately, I don't understand how can apply mkMerge here. Is the
following example correct?

  containers.test-1.config =

let cfg1 = {

  networking.extraHosts = ''

10.10.10.10 bla1

  '';

};

cfg2 = {

  networking.extraHosts = ''

11.11.11.11 bla2

  '';

};

  in lib.mkMerge [

cfg1

cfg2

  ];

It doesn't do what I want:

$ sudo nixos-container run test-1 -- cat /etc/hosts
127.0.0.1 localhost
::1 localhost

11.11.11.11 bla2

Maybe I should reference somehow to base modules?

[Nix-dev] evalModules: how to use it?

[Daniel Hlynskyi]

Hi. I have a container generator:

mkContainer =
{ config, lib
, additionalConfig ? {}
}:
let
  containerParams =
   { autoStart = true;
   };
in
containerParams //
{ config = { config, pkgs, lib, ... }:
  { imports = [
  
  
  
];

networking.firewall.enable = false;
  } // additionalConfig;
}

And I have a container

containers.test = mkContainer { inherit config lib;
  additionalConfig = {
networking.firewall.enable = lib.mkForce true;
  };
};

But this is wrong - I can't just // two configurations. AFAIU there is
lib.evalModules function. How can I use to implement custom overrides?
My mind is already blowned with it's implementation and dozens of different
ways to use it are tried with no success.

Re: [Nix-dev] Best way to install nix packages from github repo

[Daniel Hlynskyi]

All approaches listed here share common pitfall - you have to download not
only latest Nixpkgs tarball, but whole new stdenv and co to use that 1
package.

But often cherry-picking that new package and deps to local Nixpkgs is the
only thing required, without all of that updated stdenv.

I see replaceRuntimeDependencies and nbp's approache for quickfix packages
as a step toward nice solution to this problem. But haven't used them yet.

Re: [Nix-dev] Separate repository for autogenerated lists of urls and hashes

[Daniel Hlynskyi]

Now, when I've done some package upgrades and downgrades, I really like the
idea of a separate srcs repo. I'd like to contribute 3 ideas.

1. Use some of monitor.nixos.org logic for srcs updating
2. Autoextract src information from nixpkgs to srcs
3. Add meta.updateSrcsScript or meta.listAllSrcs in cases where
monitor.nixos.org heuristics are not smart enough

Re: [Nix-dev] User-oriented nixpkgs documentation (was: ioquake3 on nixos)

[Daniel Hlynskyi]

Write a blog post. Though it is hard to maintain blog post content over
time, ask yourself "how long am I able to maintain this knowledge? Who
should be responsible for verifying this manual in with future changes?"

People expect manuals to be consistent with software. Every time I find
errors in docs, I am step away from using it. From this perspective
blogposts and wiki are better place to contribute unmaintained knowledge -
we don't expect them to be always correct.

Make tags, so google can find your article with "quake nix".

Just IMO, but critique accepted.

Re: [Nix-dev] mix bundlerEnv and python3.buildEnv

[Daniel Hlynskyi]

Reason why patchShebangs doesn't work here is because `python` executable
is not accessible in the environment. Instead python is called `python3`.
So if your script used #!/usr/bin/env python3, your first example would had
worked as expected.

I think this is bug with nixpkgs python environment, python should be
accessible via `python` if it's unambiguous.

Re: [Nix-dev] Custom directories

yes, but this looks non-declarative...

OTOH this could be normally done in some existing service (in `preStart`
section), but 16.03 doesn't support `preStart` for containers. Waiting for
16.09...

Nice. But I don't want to mount /media/logs to my container, because it
will have access to other logs created by other containers.

the target directory with the permissions you want

This (permissions) would be nice feature for fileSystems too, IMO.

[Nix-dev] Custom directories

[Daniel Hlynskyi]

Hi. What's canonical Nixos way to specify custom directories?

I'm playing with containers. Here is excerpt of my config:

  fileSystems."/media/logs" = { fsType = "ext4";  label = "logs"; };
  boot.initrd.postMountCommands = ''
chmod 777 /media/logs
  '';

  containers.dwarfs =
{ bindMounts."/media/logs/dwarfs".hostPath = "/media/logs/dwarfs";
  bindMounts."/media/logs/dwarfs".isReadOnly = false;
  config =
   { config, pkgs, ... }:
   {
 boot.postBootCommands = ''
chmod 777 /media/logs/dwarfs
 '';

I'd like for directory /media/logs/dwarfs to exist, but I don't know where
to put _the_ mkdir.

boot.initrd.postMountCommands is not exactly what I want, because I need to
remount drive or reboot host for changes to apply, but plain nixos-rebuild
switch doesn't execute postMountCommands.

Also I'd like to change directory mask in containers without container
restart (instead of boot.postBootCommands)

[Nix-dev] NIX_PATH and tarballs

But when I run `nixos-rebuild` twice, I notice that tarball is not
downloaded second time.

root# NIX_PATH=nixos-config=/etc/nixos/configuration.nix:nixpkgs=
https://github.com/NixOS/nixpkgs-channels/archive/nixos-unstable.tar.gz \
root#   nixos-rebuild dry-build

these derivations will be built:

  /nix/store/rflgcrmas917yzdihxd9kqbp8n27w2qj-dbus-conf.drv

What kind of caching is this and what happens when upstream tarball changes?

nix-channel in favor of tarball links. Is anybody aware of what the new

Re: [Nix-dev] [***SPAM***] Thoughts on the Nix model

[Daniel Hlynskyi]

Nice way to establish "declarativeness" of Nix expressions is to integrate
OWL (or any other description logic based language) into Nix such that we
can do (lossy) translation nixpkgs -> .owl and query results with existing
OWL tooling.

The list of queries Nix itself does not support is a first thing to do in
this case

[Nix-dev] PyQt and packaging python-qscintilla

[Daniel Hlynskyi]

For PyQt there is a library python-qscintilla, which is Python binding to
qscintilla editor control. PyQt is already packaged here [1].

The problem with packaging python-qscintilla is: it wants to be in PyQt
directory. So we can do

  import PyQt4
  import PyQt4.Qsci

Now [2] I have three choices how to resume packaging :

1) ask if someone knows hot to trick Python and sip where the Qsci.so is
located (python-qscintilla creates .so file, not .py). I've tried to put
Qsci.so into PYTHONPATH but Python doesn't load .so files (or I didn't
figure out how it works)

2) modify PyQt, so it has optional argument qscintilla:

   pyqt4 = { pkgs, qscintilla ? null, ..} : ...

and refer to python-qscintilla as

   [ pkgs.python27Packages.pyqt4 { pkgs = self.pkgs, qscintilla =
pkgs.qscintilla } ]

(alternative: implement it as override in nixpkgs)

3) create own build of PyQt in python-qscintilla. This will not change
existing PyQt expression

Which is better to continue and how to do it best?

[Nix-dev] services.xserver.displayManager.auto does not work

[Daniel Hlynskyi]

Hi. I'm trying to run window manager without login prompt.
I'm using displayManager.auto, but it results into xterm without WM.

It uses under the hood SLiM, so the following config does not work either

 displayManager.slim =
{ enable = true;
  defaultUser = "danbst";
  autoLogin = true;
};

Logs say:

Jun 20 10:42:31 master display-manager-start[7860]:
/nix/store/msj1a9rsch74cy3mwb8vbsamq7hsiay6-xauth-1.0.9/bin/xauth:  file

Jun 20 10:42:34 master display-manager-start[7860]:
/nix/store/msj1a9rsch74cy3mwb8vbsamq7hsiay6-xauth-1.0.9/bin/xauth:  file
/home/danbst/.Xauthority does not

How can this be fixed or overriden to run window manager with specific user?

Re: [Nix-dev] Problem with builder #1 - nix-shell and nix-build behave differently

[Daniel Hlynskyi]

I propose

postUnpack = "cd $sourceRoot"

That won't break already-unpacked-source-environments
If one wants old behaviour, he can do "unpackPhase; cd .."

Re: [Nix-dev] Problem with builder #1 - nix-shell and nix-build behave differently

[Daniel Hlynskyi]

Why not? unpackPhase unpacks to current dir, why can't it switch to
$sourceRoot?
If I understand nix-shell right, it would be then possible to

nix-shell --command "unpackPhase; configurePhase; buildPhase;"

as kind of alias to nix-build. Currently you are required to cd as
mentioned in wiki [https://nixos.org/wiki/Debugging_a_Nix_Package]

As Tomasz Kontusz mentioned, the cd $sourceRoot is done between phases,
which is unexpectable to me.

Then how does nix-build handle this? Is there some special hook "cd
$sourceRoot" after unpackPhase? Why this hook is not added to nix-shell?

[Nix-dev] Problem with builder #2 - $out variable is escaped in configureFlags

[Daniel Hlynskyi]

Problem: $out path is escaped in configureFlags and not expanded in
configure time
to /nix/store/i02i938nm28zjxx0hswxx4bc5pknqzaj-qscintilla-python
However, when I write custom configurePhase script via double-singleticks
and explicit EOL-escaping, it works. How can I achive this with
stock configureScript and configureFlags?

Input #1: default.nix

let
 pkgs = import  {};
in rec {

  qscintilla-python = pkgs.stdenv.mkDerivation rec {
name = "qscintilla-python";

src = pkgs.qscintilla.src;
buildInputs = [ pkgs.python ];
propagatedBuildInputs = [ pkgs.pyqt4 pkgs.qscintilla pkgs.qt4 ];

preConfigure = "cd Python";
configureScript = "${pkgs.python}/bin/python configure.py";
configureFlags = "
  --destdir $out/lib/${pkgs.python.libPrefix}/site-packages
  --no-sip-files
  --no-qsci-api
  --pyqt PyQt4
  --qsci-incdir ${pkgs.qscintilla}/include
  --qsci-libdir ${pkgs.qscintilla}/lib
";
dontAddPrefix = true;

  };
}

Input #2: default.nix with custom configure step

let
 pkgs = import  {};
in rec {

  qscintilla-python = pkgs.stdenv.mkDerivation rec {
name = "qscintilla-python";

src = pkgs.qscintilla.src;
buildInputs = [ pkgs.python ];
propagatedBuildInputs = [ pkgs.pyqt4 pkgs.qscintilla pkgs.qt4 ];

configurePhase = ''
  cd Python
  ${pkgs.python}/bin/python ./configure.py \
  --destdir $out/lib/${pkgs.python.libPrefix}/site-packages \
  --no-sip-files \
  --no-qsci-api \

[Nix-dev] Problem with builder #1 - nix-shell and nix-build behave differently

[Daniel Hlynskyi]

Problem: nix-build and nix-shell treat differently source root directory
When using nix-build, shell is in $sourceRoot after unpackPhase, when using
nix-shell, it is left in current directory. How can I make nix script
behave same when nix-building it and nix-shelling?

Side problem: is there shortcut for `${pkgs.python}/bin/python`?

How to reproduce:
run `nix-build default.nix`
then run `nix-shell default.nix --command "rm -rf QSci*; unpackPhase;
configurePhase"`
notice, that second one failed preConfigure step

Input: default.nix

let
 pkgs = import  {};
in rec {

  qscintilla-python = pkgs.stdenv.mkDerivation rec {
name = "qscintilla-python";

src = pkgs.qscintilla.src;
buildInputs = [ pkgs.python ];
propagatedBuildInputs = [ pkgs.pyqt4 pkgs.qscintilla pkgs.qt4 ];

preConfigure = "cd Python";
#preConfigure = "cd $sourceRoot/Python";  <- correct for
nix-shell, but wrong for nix-build
configureScript = "${pkgs.python}/bin/python configure.py";
configureFlags = "
  --destdir $out/lib/${pkgs.python.libPrefix}/site-packages
  --no-sip-files
  --no-qsci-api
  --pyqt PyQt4
  --qsci-incdir ${pkgs.qscintilla}/include

[danbst@master:/tmp/scibuild]$ nix-build '' -K -A qscintilla
--option build-use-substitutes false
/nix/store/kycs9akg1h70wjm0p4cg9cc384ccrfy7-qscintilla-2.8.3

[danbst@master:/tmp/scibuild]$

I have 'gc-keep-outputs = true' option enabled. Can this be a problem?

[Nix-dev] force nix-build without binary caches?

[Daniel Hlynskyi]

hi, I'm trying to use -K option for nix-build, but it doesn't generate
unpacked directory in /tmp, it simply finds it somewhere in cache (or

[Nix-dev] I'd like to package 'python-qscintilla2' from Debian. How should I do that?

[Daniel Hlynskyi]

Hi. I'm going to create a package from Debian one, 'python-qscintilla2' and
it's usage 'tortoisehg'. What manuals should I read first, what examples
should I take into account, what naming conventions should I consider and
what workflows are there to simplify package process?

Wiki and manual information is helpfull, but not enlighting. I'll start
there, but maybe someone can point me to better docs/examples on package
process?

In particular:
- is there simple way to convert existing Debian (or Arch/AUR) package to
Nix?
- testing package isolated to system
- nix derivation syntax and semantics (from scratch and for dummies)
- nix derivation workflow patterns for dummies
- nix naming and versioning patterns for dummies
- maintaining

Best, Daniel

sure. That is the point of rolling-release distros (like NixOS). You can
update from any point in history (aww, there are exceptions ^))

The command to update system is

nix-channel --add http://nixos.org/channels/nixpkgs-unstable
nixos-rebuild switch --upgrade

I don't know whether it will update kernelPackages to new one. If that ata1
is kernel bug, than you have to figure out, which kernel it was introduced.

Re: [Nix-dev] NixOS Live CD (Graphic) Boot Failure

[Daniel Hlynskyi]

Why do you have problems with flash-boot and have to burn discs? Maybe
there is some problem with your flash-drive? You can try another one.

You can also try some truly old NixOS, pre-systemd one, for example or 2.x
kernel.

[Nix-dev] Correct way to solve `libgcc_s.so.1` problem

[Daniel Hlynskyi]

I'm using GHCi (inside load-env-haskell). It happend that I Ctrl-C'anceled
a threaded program and GHCi was killed with "libgcc_s.so.1 must be
installed for pthread_cancel to work"

So now I have to instruct GHCi to find this library. But what is the proper
way to do so in NixOS? I've found existing solutions
([1],[2],[3],[4],[5],[6],[7],[8]) but cannot figure what to choose and
where to write those magic lines.


[1] guile:

  # Explicitly link against libgcc_s, to work around the infamous
  # "libgcc_s.so.1 must be installed for pthread_cancel to work".
  # don't have "libgcc_s.so.1" on darwin
  LDFLAGS = stdenv.lib.optionalString (!stdenv.isDarwin) "-lgcc_s";

[2] glibc

# When building glibc from bootstrap-tools, we need libgcc_s at RPATH
for
# any program we run, because the gcc will have been placed at a new
# store path than that determined when built (as a source for the
# bootstrap-tools tarball)
# Building from a proper gcc staying in the path where it was installed,
# libgcc_s will not be at {gcc}/lib, and gcc's libgcc will be found
without
# any special hack.
preInstall = ''
  if [ -f ${stdenv.gcc.gcc}/lib/libgcc_s.so.1 ]; then
  mkdir -p $out/lib
  ln -s ${stdenv.gcc.gcc}/lib/libgcc_s.so.1 $out/lib/libgcc_s.so.1
  fi
'';

  preCheck =
# Make `libgcc_s.so' visible for `pthread_cancel'.
'' export LD_LIBRARY_PATH="$(dirname $(echo
${stdenv.gcc.gcc}/lib*/libgcc_s.so)):$LD_LIBRARY_PATH"
'';

# These binaries need to find libstdc++ and libgcc_s
for i in aidl libLLVM.so
do
patchelf --set-rpath ${stdenv_32bit.gcc.gcc}/lib $i
done

Hello. There is a convention to convert haskell packages names to camelCase

So what convention should I use when submitting new haskell packages to

[Nix-dev] Various NetworkManager (and KDE) problems

this in configuration.nix/networking:

#wireless = {
#  enable = true;

networkmanager.enable = true;

Though NetworkManager.service fails after rebuild:

Anyway, after that I can do
   systemctl start NetworkManager.service
and it starts without complaining. Arch-users say it is a known
problem with systemd/networkmanager. Is there a way to make it start
automatically on NixOS?

2. The KDE applet networkmanagement fails to start

# networkmanagement_configshell --connection dd-wrt create
QDBusConnection: session D-Bus connection created before
QCoreApplication. Application may misbehave.
networkmanagement_configshell(1910): KUniqueApplication: Cannot find
the D-Bus session server:  "Did not receive a reply. Possible causes
include: the remote application did not send a reply, the message bus
security policy blocked the reply, the reply timeout expired, or the
network connection was broken."

networkmanagement_configshell(1909): KUniqueApplication: Pipe closed
unexpectedly.

Though, there is a workaround (thanks to Arch users!):
# export $(dbus-launch)

I don't know why, but it solves problems with NetworkManagement applet
and ocular (yes, ocular cannot open documents without this hack). How
can I add this command at system startup or maybe it is a bug and will
be fixed soon?

Thanks, this command didn't fail and downloaded new packages. BUT new package
binaries are NOT RUNNABLE. Bash says that. So now I have runnable (but
old) nix-env
in one shell, and not runnable in all new shell tabs. The problem is
not only with
nix-env, perl is not runnable also.

old runnable nix-env hosts in `/run/current-system/sw/bin/nix-env`
new nix-env hosts in `/nix/var/nix/profiles/default/bin/nix-env`

Thanks. That helped a bit. Now I have a problem:

Is it possible to recover from this point?

[Nix-dev] Cannot upgrade old NixOS

[Daniel Hlynskyi]

I have trouble to do upgrade NixOS. What is the easiest way to solve this
problem? Do I need to reinstall NixOS from scratch?

Re: [Nix-dev] [Hackage] How to install Hackage package, not presented in nixpkgs, locally?

[Daniel Hlynskyi]

There were theese lines in the end of ghc-pkg output log:

 The following packages are broken, either because they have a problem
listed above, or because they depend on a broken package.
pipes-core-0.1.0
pipes-core-0.1.0

And yes, I tried to load Control.Pipes in ghci. It worked not.

Now I solved this problem with manual `categories` install. I suppose, you
haven't noticed any problems, so the question is partly closed (I have to
do pull request to nixpkgs with appropriate patch)

Re: [Nix-dev] [Hackage] How to install Hackage package, not presented in nixpkgs, locally?

[Daniel Hlynskyi]

Steps:
1. ~$ git clone https://github.com/NixOS/nixpkgs.git
2. ~$ cd nixpkgs/pkgs/development/libraries/haskell/; mkdir categories;
mkdir pipes-core; cd ../../../../
3. nixpkgs$ cabal2nix cabal://categories-1.0.3 >
pkgs/development/libraries/haskell/categories/default.nix
nixpkgs$ cabal2nix cabal://pipes-core-0.1.0 >
pkgs/development/libraries/haskell/pipes-core/default.nix
4. edit pkgs/top-level/haskell-packages.nix
5. edit pkgs/top-level/haskell-default.nix to add FORCE_REBUILD = 1; (but
maybe this is redundant, because hash-warnings were not solved)
6. nixpkgs$ nix-env -f . -iA haskellPackages.pipesCore
7. nixpkgs$ ghc-pkg check

[Daniel Hlynskyi]

Oh! Realy! Kind of magic.

After rechecking found, that installing `pipes-core` package didn't install
`categories` package, .nix file for which I added also. When I installed
`categories`, it worked. Is it a bug? `Categories` package is mentioned in
dependencies in pipes-core/default.nix

Do I understand correctly, change haskell-default.nix and reinstall it with

[~/nixpkgs]$ nix-env -f . -iA haskellPackages
?

I am failing to do this with another, not related problem:
...
installing `haskell-zlib-ghc7.4.1-0.5.2.0'
installing `haskell-zlib-ghc7.4.1-0.5.3.1'
error: user-thrown exception: cudatoolkit does not support platform
i686-linux
(use `--show-trace' to show detailed location information)

So I cannot finish haskellPackages install.

Oh that was easy. I had to do this:

[danbst@localhosted:~/nixpkgs]$ nix-env -f .  -iA haskellPackages.pipesCore
or build with
[danbst@localhosted:~/nixpkgs]$ nix-build -A haskellPackages.pipesCore

But dependency hell was not gone.


   1. pipes-core-0.1.0: dependency
   "base-4.5.0.0-f76ceb9607ba9bd4fcfb9c7b92d8cfe1" doesn't exist (ignoring)
   2. pipes-core-0.1.0: dependency
   "categories-1.0.3-e9ab00168a7d0fdacafd64b31a5e1100" doesn't exist (ignoring)
   3. pipes-core-0.1.0: dependency
   "lifted-base-0.1.1-51e1520336adbfccd889e58e684c89a1" doesn't exist
   (ignoring)
   4. pipes-core-0.1.0: dependency
   "monad-control-0.3.1.3-a94da65cc1c2dcd38097f790cd885593" doesn't exist
   (ignoring)
   5. pipes-core-0.1.0: dependency
   "transformers-0.3.0.0-f2303dfef836518cc2f6901210442e10" doesn't exist
   (ignoring)
   pipes-core-0.1.0: dependency
   "void-0.5.6-2a27beac32f0c526d6cb6dc79bccfbd9" doesn't exist (ignoring)
   6.

What I don't understand, are the hashes. Where are they from and how to
solve theese dependency problems?

[Nix-dev] [Hackage] How to install Hackage package, not presented in nixpkgs, locally?

[Daniel Hlynskyi]

Hello. I'm trying to create an installable package for `pipes-core` Hackage
package.

But got in troubles.

1. I used cabal2nix, but failed on installing the .nix file. After googling
some time, I've done `nix-env -f all-packages.nix -iA
haskellPackages.pipesCore`, so I've got package locally. But it had not
registered the package, log with reasons http://pastebin.com/jp350qvX
Manual registration with `ghc-pkg register` helped not. I don't know what
to do now.

2. How can I contribute to nixpkgs with this package? The main question is
- how can I TEST my contribution, when I get it?
