[Nix-dev] Git branches to track nix channels
Hi, nix channels are series of snapshots of nixpkgs that were succesfully build by hydra and we subscribe and update them via nix-channel - for users of nixpkgs this is great! As maintainers of nixpkgs and users who keep custom patches, we also have one or more local checkouts of git://github.com/NixOS/nixpkgs.git. It would be great if channel information would be available via git as well: - one branch per channel, git reset --hard to the latest successfully build nixpkgs in this channel - tags (channel-name-datetime) for each successful channel build. This would enable us to base local customizations of nixpkgs on-top of successful hydra builds and therefore getting as much binary package support as possible, and would remove the need to additionally maintain channels with nix-channel. What do you think? cheers florian -- Florian Friesdorf f...@chaoflow.net GPG FPR: 7A13 5EEE 1421 9FC2 108D BAAF 38F8 99A3 0C45 F083 signature.asc Description: PGP signature ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev

Hi Florian, What is the reasoning to have these in a separate repository? We don't want notification e-mails sent out every time the channel updates, which would happen if these branches were pushed to the main repository.

Re: [Nix-dev] Confused about packages
Wouldn't it be better for version numbers to always exist? That way it's simple to know the exact version of your package that you're installing, even if it's just one package. I'd prefer for it not to be random. On 16/05/2015 7:27 AM, Vladimír Čunát wrote: Hi. On 05/15/2015 11:09 PM, Amy de Buitléir wrote: Q 1. Why do some packages have version numbers, and some don't?

Why can't I find some packages that I would expect to find? Are they hidden? For example, I have the following in my /etc/nixos/configuration.nix: environment.systemPackages = with pkgs; [ dmenu2 dzen2 haskellPackages.xmonad haskellPackages.xmonadContrib haskellPackages.xmonadExtras wget xsel ]; But if someone hadn't told me the names to put there, how could I have found the names of the packages? Searching for them using nix-env didn't find them: I consider that a bug, too. Peti: I guess this would be because of haskellPackages missing recurseIntoAttrs. I can't see it in there and no haskell packages are shown for me on master.

Re: [Nix-dev] Confused about packages
Excerpts from Roger Qiu's message of Tue May 19 05:56:30 + 2015:
Wouldn't it be better for version numbers to always exist?
You're totally right that the
mkDerivation {
name =name-version
}
version should always exist. Thus if you find cases just create a topic
branch, fix, and submit once in a while.
I was quite surprised that mysql in all-packages.nix started pointing
to mariadb which broke my ruby overlay because headers were not found.
Thus what can you do?
there is builtins.compareVersions function, and there are nixos module
assertions - thus you could ensure this way that compareVersion
pkgs.mysql equals 5.0 or so - or you could just add a constraint
mysql.name = mysql-5.0 which would fail building.
You always know the version as long as you're using the same nixpkgs
revision - but sometimes you have to update - and then adding such nixos
assertios would be close to what you want. Just grep nixpkgs/nixos for
assertions to see samples.
However usually upgrades just happen to work fine - in the end testing
for versions doesn't protect you from mal functioning (eg a dependency
could have changed) - thus what you really want is writing tests.
There are some samples in the nixpgks repository as well.

Listing the tags will quickly become unwieldy, but for a persistent reference it will be more readable to have channel-date than some random hash (or maybe channel/date or something). It might be also nice for things like git describe. Maybe there's a better way to achieve those, I don't know. I'm uncertain if there might be some performance implications when working on a repo with too many tags, but as this won't be in the main repo, we can easily chance it.

[Nix-dev] luks encrypted home stopped mounting after channel update
A few days ago, I ran `nixos-rebuild --switch` using the up-to-date
unstable channel, and everything worked fine. Last night I updated
the channel again and rebuilt, but when I started my computer this
morning, it doesn't prompt for the encryption password anymore, and
home doesn't mount. Any ideas?
I can get into my system by telling GRUB to boot the previous
configuration instead, so the partition itself is fine. Nothing
changed in my configure.nix. Here are the relevant lines:
---
# Use the GRUB 2 boot loader.
boot.loader.grub.enable = true;
boot.loader.grub.version = 2;
# Define on which hard drive you want to install Grub.
boot.loader.grub.device = /dev/sda;
# Encrypted home
boot.initrd.luks.devices = [ { device = /dev/sda6; name = home; } ];
fileSystems./home.device = /dev/mapper/home;
---
And this is my hardware-configuration-lorax.nix:
---
# Do not modify this file! It was generated by ‘nixos-generate-config’
# and may be overwritten by future invocations. Please make changes
# to /etc/nixos/configuration.nix instead.
{ config, pkgs, ... }:
{
imports =
[ nixpkgs/nixos/modules/installer/scan/not-detected.nix
];
boot.initrd.availableKernelModules = [ ehci_pci ahci xhci_hcd
usbhid ];
boot.kernelModules = [ kvm-intel ];
boot.extraModulePackages = [ ];
fileSystems./ =
{ device = /dev/sda5;
fsType = ext4;
};
swapDevices =[ ];
nix.maxJobs = 4;
}
---
The error message in `journalctl -xb` is:
May 20 04:50:55 lorax systemd[1]: Job dev-mapper-home.device/start timed out.
May 20 04:50:55 lorax systemd[1]: Timed out waiting for device

Check on /dev/mapper/home.
The AES encryption modules is loaded, though.
Any ideas about how to get the system to ask for my encryption
password again? Much appreciated,
Ellis

Re: [Nix-dev] Leap Second
Yeah, leap second(s) are a big issue since that's the code that nobody really tests. NixOS is going to have as much problems as the software you're running has bugs. Google is smart here, they're adding microseconds over a longer span of time via their NTP, so the extra second doesn't disrupt any services and is synced with the rest of the world at the switch time.
