jsgrant_: it seems strange to me that GC would get rid of stuff I'd installed explicitly
<Ralith>
hodapp: I generally try to put the bare minimum in configuration.nix, and then declaratively specify all my user environment stuff and manage it as a monolithic unit installed as a single package with nix-env
<Ralith>
hodapp: nix will not GC stuff that's in a selected profile

i.e. things installed with nix-env
<jsgrant_>

No big deal either way, I now assume it is/was user-error & only happened that one time that I am aware of. :^P
fritschy has joined #nixos
<Ralith>
it's interesting to consider, though; user error is documentation error
<jsgrant_>
Sometimes true, but at the time I was only pecking around & wasn't as serious as I am now about learning the envrioment -- so I don't put that much credence beyond that of user-error. Speaking of documentation errors though, still need to check bugglist if there is something on KDE's khelpcenter being borked in plasma5.

different packages sometimes need different versions of some things, and things sometimes turn stuff on automaticaly if header X is found in the include path
<clever>
which may not be something you wanted enabled

Armael: You can install things into your system profile, if you want. You just have to make sure that you're choosing packages that actually work for what you're trying to do. And the global gcc binary you currently have clearly doesn't.
<Armael>
fair enough
<Armael>
I'm not sure I understand why it doesn't, though
<peti>
Armael: I don't either. The only reason I could think of is that you installed a plain gcc instead of the gcc-wrapper that nix-shell relies on. But it's hard to tell without beng able to look at your system.
<Armael>
it's probably a plain gcc yes
<Armael>
what does gcc-wrapper do?
<Armael>
ah wait, gcc-wrapper is nixos.gcc
<Armael>
mmm
<Armael>
it should be gcc-wrapper then
<peti>
gcc-wrapper interprets the env variables set by nix-shell (among other things).
<Armael>
well for the gmp.h, it was just that I didn't know about gmp.dev, I think
<peti>
Armael: I thought you said that "nix-shell -p gmp.dev" didn't work?
<Armael>
it didn't
<peti>
Armael: But "nix-shell -p gmp.dev -p gcc" did?
<Armael>
yes
<peti>
Well, that's gonna need some investigation then, because if your global gcc is working correctly, then there should be no difference between those two environments.
<peti>
Armael: Anyhow, if in doubt, run nix-shell with "--pure". That should help avoid these kind of issues.

How can I link nixpkgs-channel to nixpkgs? So, let's say I know that I want version `eeeeeef` from nixpkgs, how can I check whether nixpkgs-channel already has it?
<jsgrant_>
ToxicFrog: Is there any advantage even using an alternative shell, besides compilation needing it for somereason (and/or making an extensions for it)?
<MoreTea>
@domenkozar,gchristensen: are you going to FOSDEM in feb 2017?
<gchristensen>
jsgrant_: personal preference
<gchristensen>
MoreTea: unlikely, fosdem is very far for me
<LnL>
domenkozar: is that since you made is statically linked?
<domenkozar>
yes
<ToxicFrog>
jsgrant_: so, I'm generally using nix-shell interactively, not to use build scripts
<domenkozar>
LnL: I'm trying to statically link also the resulting binary
<ToxicFrog>
which means that if it's zsh it gets my .zshrc and history syncing and all that fun stuff
<ToxicFrog>
And if it's bash it gets the default bashrc
<ToxicFrog>
Which doesn't really match my preferences, because I haven't spent any time configuring it, because I never use bash interactively.
<jsgrant_>
ToxicFrog: Even in nix-shell?
<LnL>
domenkozar: is it supposed to be looking at /nix/store/5an661jgv6655kf37srva02jwzpavw9n-rocksdb-4.13/lib/librocksdb.a at this point?
<ToxicFrog>
...yes?
<ToxicFrog>
I don't understand the question.
<domenkozar>
LnL: yes
<LnL>
domenkozar: if you statically linked against rocksdb before, won't you have that stuff in your current object files?
* jsgrant_
guess he just assumed that nix-shell was "different enough" from the current session that you'd have to define such things (like dotfiles, plugins, etc) non-locally.
<ToxicFrog>
Nope, seems to work just fine
<ToxicFrog>
At least, 'nix-shell -p foo --run zsh' loads all my normal zsh configuration.
<ToxicFrog>
(it occurs to me that I could even have my prompt check for $IN_NIX_SHELL and change appropriately)

MoreTea: Doesn't help that people (certainly like me), jump in head-first & don't do a more sensible cursory sweep before getting fairly invested. :^P

Maybe we should refer to Nix{,OS,pkgs,Ops} ‘manuals’ as ‘guides’. Less scary ( ͡~ ͜ʖ ͡°)

kmicu, when I started 1.5 year ago, I felt that a) The split between Nix{,OS,pkgs,Ops) was not obvious from the website and b) that the manuals go into the low level details directly.
<gchristensen>
I agree, MoreTea
<MoreTea>
All the information is one big "reference manual". I think we need a set of easy to digest guides that get people interested. Once they are convinced that what Nix* does is awesome by showing off it's strengths, they won't mind to dive deep into the manuals and not understand everything at once.

gchristensen: supposedly nixpkgs-unstable got updated, but when I refer to the nixpkgs-channel and then branch nixpkgs-unstable, terraform is still at some old version.
<rly>
gchristensen: to me it appears that at least that repository was not updated.
<LnL>
gchristensen: one of the main things to note is that it won't overwrite existing etc files, so you might have to fiddle with you bashrc,zshrc to make it load the nix versions from /etc/static
<gchristensen>
aye
<LnL>
the nixos activation script for etc files just overwrites everything :p
<gchristensen>
yeah I know, haha, it is very ... efficient!
<MoreTea>
@hellooo, I guess yes ;) If you're trying to automate communication between your own programs and Nix, you might want to look into dump JSON from your program, and using `builtins.fromJSON`
<LnL>
gchristensen: /run is is / so it's the same

@gchristensen, do you have any ideas about how to reduce the number of times that Hydra stalls?

One could argue that NixOS is source based distro and you do not need official Hydra at all. If you tested CVE patches locally then merge them into Nixpkgs. But in such case channels’ users could feel ‘cheated’ by false advertising.
<gchristensen>
you could, but the development style is frequently to push things without as thorough testing due to the testing hydra provides
<LnL>
^ we could publish a new channel, but stuff might be completely broken who knows.

From another point of view, broken official Hydra would not be a problem if we had a community–driven Hydra, not controlled by handful of users, and where you could use Nix/Hydra versions with merged long–standing Nix/Hydra PRs 😸

manveru: heh, that's silent no? :p I don't think it has any options
<maurer>
Would it be prohibitively expensive to have a sort of release hydra for unstable/stable channels, separate from the more C-I nature of the nixpkgs one? It seems like that should be much lower on the needed resources
<maurer>
since it'd only need to trigger a rebuild on security updates or a new release cut
<manveru>
LnL: well, i can work around it by caching the stderr, then checking the exit status, and printing stderr in case it's !=0
<gchristensen>
kmicu: I know that when I was estimating a project, I was looking for sponsorship of $1,000/mo for the build servers, but that was likely to have more load than your proposed hydra would be. note that much of the nixos hydra resources are donated by rackspace, mackstadium, and others

c0bw3b: the trouble is trust

why should I trust your machine, c0bw3b, to provide safe builds?
<maurer>
gchristensen: I mean, you could do something like what debian developers do, but that'd probably be a step backwards for nixos imo
<gchristensen>
it would be indeed
<maurer>
(If you are on x86 or amd64, and are using debian, chances are that package you're using was built by Some Guy's Laptop, but it's probably OK because Some Guy has been with Debian for a while and seems Legit)
<kmicu>
I could challenge hashes from c0bw3b’s server with hashes from official Hydra server. I could exchange keys with c0bw3b during NixOS meetup, b/c she/he is trustworthy. I would be safe for 77% of packages that are bit–by–bit reproducible. I could allow only them with hypothetical ‘allowReproducible’ flag. It’s a good trade–off IMO, especially for casual users w/ casual threat models.

E.g. because it takes 8GB of memory.

Hi All!
<kuznero>
Can anybody recommend how is it best install Spacemacs (with Intero) on NixOS?
<toogley>
kuznero: i just installed emacs normally and installed spacemacs ontop of it manually.
<toogley>
kuznero: => if you get to know anything better than that in the future, i'd be interested in hearing about that :)

Hi. I'm trying to get started with NixOS using the VirtualBox appliance. I need KDE to handle HiDPI properly so I enabled it in /etc/nixos/configuration.nix. Then I was warned not to enable KDE 4 and 5 at the same time so I disabled KDE 4 in the place. Now I'm getting an error message:
<NodeGuy>
rror: The option `services.xserver.desktopManager.kde4.enable' has conflicting definitions, in `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/nixos/modules/profiles/graphical.nix' and `/etc/nixos/configuration.nix'.

@NodeGuy, we have some support for generating nix expressions from packages.json (given your name, I thought that might have your interest ;)
<NodeGuy>
Yes and I'm very excited about it. I tried Guix first but it had inadequate support for VirtualBox and I don't have bare metal right now.
eacameron has quit [(Ping timeout: 245 seconds)]
<MoreTea>
I see. What are you running? Linux? Or OSX?
<NodeGuy>
And yes, I am interested in nix expressions from packages.json, that sounds very cool. Do you have a link?
<NodeGuy>
I'm currently running Mac OS but am planning on transitioning to Qubes OS. I'm using VirtualBox during my transition.
<NodeGuy>
I'm working on creating a kind of Qubes-lite right now with Nix and containers during my transition.
<NodeGuy>
and plan to keep using Nix once I'm in Qubes.
<MoreTea>
OK, Nix (the package manager) also runs on top of OSX, so you could use it instead of Homebrew, in theory. In practise there are not enough developers to maintain all packages AFAIK.
<NodeGuy>
Thanks, I'm in the process of getting off of OS X so that's not as interesting to me.
<MoreTea>
That would be an interesting combination ;)
<LnL>
it depends on what you want to use
<NodeGuy>
My security requirements are going up.
<NodeGuy>
Yeah, I think the Qubes people will love NixOS. It's a natural match. They are adamant about minimizing state.

@simpson, any reason that you have chosen it to be dynamically typed? My preference is slowly moving to statically typed languages.

<garbas>

<simpson>
MoreTea: Well, it's statically typed with a very boring type; objects require a uniform interface.
<dash>
garbas: hi again :)
<dash>
MoreTea: Static typing is nice when it suits the problems at hand, but it necessarily restricts certain things
mbrgm has quit [(Ping timeout: 258 seconds)]
<simpson>
MoreTea: But basically it's my position that any type system that can actually prevent bugs is necessarily not flexible enough to handle The Filesystem and The Network.
<dash>
MoreTea: for instance, the type checker has to be able to look at all the code (or at least the interface for all the code) that you want to invoke in a program
<dash>
and for distributed systems this is not possible

I still should create a systemd one-shot service that restricts the memory to max 2g...

Sometimes rebuilding things like kubernetes crash after 30 minutes of compilation, due to OOM, because the ARC is not released fast enough.

I'm following along with the manual and I wanna build GNU Hello without modifying the Nixpkgs source code. In note 3 here <https://nixos.org/nix/manual/#sec-arguments> there seems to be a really big hint at how to do this. But I can't figure out how to actually invoke 'callPackage' from the command line
<gchristensen>
MoreTea: usually all the firefox ones are resolved in one go, by making sure each are up to date with the most recent release
<newdan>
I tried `nix-build '<nixpkgs>' -E 'hello = callPackage ./default.nix {};'` but it says the expression does not evaluate to a derivation
<viric>
MichaelRaskin: I think it defaults to taking 50% of RAM, but you can tune the 'ARC' to use much less
<newdan>
MoreTea: Gives the same error (the command line version anyway, I'll try modifying the source)
<MichaelRaskin>
ToxicFrog: because I don't understand why a Nix build would want to interact with that file. Does the file exist? Is it a regular file? What is its creation/modification time?

When `system.activationScripts` are executing? Is it before or after packages are getting installed in *nix files?
siel has joined #nixos
<LnL>
kuznero: first the entire system profile is built and then the activation scripts are executed to link the /etc files and stuff like that
<kuznero>
LnL: but are packages getting installed as part of building entire system profile? For example is it safe to defined stack package (Haskell stack) and in activation script run `stack setup --nix`?
nh2_ has quit [(Ping timeout: 246 seconds)]
<LnL>
I wouldn't add stuff to the activation scripts unless you have a really good reason to do so
<kuznero>
LnL: I see, but what is the alternative? Because currently I end up calling such things manually: `stack setup --nix && stack install ghc-mod && stack install hlint`. Should I keep doing that or there is a better way of putting it under control in NixOS?
<LnL>
I would use nix-shell for projects, and you can add a shellHook if you want to do special things like that
