am I just not seeing it, or is this something different in fasterMelee's code?
<infinisil>
So maybe that's something to do with it
<clever>
hio: if you want something to happen on every new commit, you need something like hydra or travis
<clever>
hio: it will be a broken symlink if you have never nix-env -i'd something before
<clever>
hio: when you install something with nix-env -i, it will read ~/.nix-profile/manifest.nix, mutate it (add a new package), then build a new profile from that, and update the symlink that .nix-profile is pointing to
<ottidmes>
infinisil: In the case of bitwarden_rs its also something I should create a PR for, but I am not sure how to go about Rust packages. I was only able to make it work with Rust on unstable (which probably should be ok, since PR are mostly done on master, but still)
<dramforever>
nix-build -E '(import <nixpkgs> {}).callPackage ./fasterMelee.nix {}' or something like that
<dramforever>
If that prints the wrong version then yes it's 'something's different'
<dramforever>
also, an idea that would take some time again: try doing something like your-thing --version at the end of postBuild
<dramforever>
maybe it's something else
<booglewoogle>
something's different
<booglewoogle>
something's there
<ottidmes>
booglewoogle: if you run installPhase via nix-shell, it executes the function that does the generic installPhase, you have to run something like: eval $installPhase instead
<booglewoogle>
yeah, I've had all phases in there before with the same error. since doing only these 3 phases in nix-shell worked, I afterwards removed any other phases from the expression because I thought "ok, maybe one of the other phases I didn't run in the nix-shell messed something up"
<erratic>
Something that kinda bugs me about the livecd is that it doesnt come with zfs progs and you have to edit the nix file and rebuild the live image ehich if you try to do without swap.. RIP
<erratic>
And nix makes what would be a pile of cookbooks, settings, and a whole server something i can do with one file allbeit only to some degree, and not always without problems
<NinjaTrappeur>
ottidmes, thanks. Yeah, I've already seen it, the install script radically changed since january 2017 :( But yeah, ultimately the problem is around the chroot namespace, that's for sure. I just can't find what's wrong. I need a personal server, so I'll ditch this whole test env and install something else

clever: thought I found something, there was a module re-exporting itself, which might have caused the linker to freak out
<Taneb>
It seems to suggest that you don't need to do much at all by way of configuration to get something, but they had to essentially copy over the generated hardware-configuration.nix to where nixops is being run from
<turion>
srhb: Yes it was, I thought you got something else interesting from the strace
<Thra11>

hi all. I'm having problems importing submodules for python packages. For instance, I can import matplotlib, but not mpl_toolkits.

Is there something I should know in general?

ixxie: does something else depend on the non-overriden version? you may need an overlay to force every other package to obey

the above is something that disables checks on prop..Nat..bui..inputs

maybe systemd-boot's options have an extraCommands or something where you can make it work
<sphalerite>
turion: a rescue boot thing is actually something where it makes a lot of sense *not* to manage it via nixos/nix directly, because otherwise you may get your rescue boot broken by the same thing that breaks your normal boot :)
<turion>
Either way, I'll try and develop something like a boot.loader.systemd-boot.extraEntries
<turion>
Well ok. I guess I'm just generally sceptical when I encounter something non-nix in a very central place in nixos
<elvishjerricco>
turion: Yea it just use `nix-env --list-generations` or something when it's run, since it is run at activation time, not build time.
<sphalerite>
turion: well you could write an expression something like (with import <nixpkgs> {}; writeText "extraEntry" (callPackage ./rescue_boot.nix).boot.loader.grub.extraEntries
<turion>
Well, I need some entry point to create something in /boot/loader/entries

If my service creates symlinks, (like under /var), when is it expected to clean them up, if ever? If I disable the service and rebuild, does it leave that junk lying around, or does NixOS do something clever? I'm looking for cleanup steps in modules but I'm not seeing any...

Has anyone had any luck compiling Oni on NixOS? I've got most of the work done but annoyingly - I can build it within a nix-shell but I can't seem to build it using my overlay. Seems to run out of memory - I'm wondering if nixpkgs does something fancy in memory instead of using disk and this is causing me to run out of memory?

It exists, is that what you mean? Or should I be doing something with it

Hmm, srhb, can't seem to get any paths signed.

is EPERM trying to open /dev/mem as root something I should be looking into NixOS to explain or somewhere else?

<Unode>
thekolb_: sometimes you need to explicitly patchelf something. Can't remember when but I had to do this once or twice

thekolb_: if yes, then instead of something from the environment you could be missing a dependency in nix

<boogiewoogie>
hey, I'm trying to package something. I think I'm almost there, except the build process isn't regular. instead, a script named 'setup' sitting in the source folder has to be run. I'm using https://pastebin.com/51Q6gewE as default.nix, and doing `buildPhase` in the nix-shell tells me there's nothing to build. what to change?

thx a lot. I knew there was something missing when reading the paper (:

schmittlauch[m]: If not, you need to do the wrapping, or something similar, to bring in the store paths of the dependencies yourself.

srhb: Funny that something essential like this isn't mentioned in the paper. Or was this approach only introduced after 2008?
<hyper_ch>

<ottidmes>
kyren: so if you want it to behave like nix-shell -p, it would become something like: nix-shell --expr 'with import <nixpkgs> {}; runCommand "dummy" { buildInputs = [ (callPackage ./. {}) ]; }' (untested)
<clever>
slack1256: no real way to know what something was built from, but you can try running nix-build -I nixpkgs=/foo -A bar on each channel generation, to see which one makes the version you want
<infinisil>
ottidmes: Wild guess: Could Nix interpret the `build` attribute as something special?

I imagine you could create multiple systemd units with nix expressions, or you could try to use instantiated services in systemd or something
<Mic92>
nix-package based. Your best bet is probably to build something with nix without shipping the package manager.

I kinda meant "I will only manage it with nixops" but maybe you meant something more like "burn a master image to media and then insert media into device"
<ottidmes>
dmj`: that is basically the same as the Arch Linux wiki I pointed to, except for the NixOS config bit of course, so it seems OK by me, I did something similar
<exarkun22>
My x86_64 machine already wants to build this derivation because it's already a dependency of something higher up

dmj`: Yes, but you can’t just jump from BIOS into decryption, you need something inbetween, that is what you have on `/boot`.

building something like kubernetes or docker should do it.

<v0|d>
interesting, so I though this propagation is done automatically via ldd or something.

AIUI propagated means that if something else declares libskba as a build dependency, it will automatically get libgpgerror as a build dependency as well

bennofs[m]: there is something called recursiveUpdate
<exarkun22>
v0|d: nope. after you asked about cross compile, I re-tried that to remind myself how it failed ... and it doesn't seem to be failing this time (or maybe the build is going in a different order or something ... or maybe my nix store is full of corrupt packages that make it look like it can skip those builds ...

I've thrown something together that will create derivations for all specified extensions on the automatic rebuild, but I'm still looking for an elegant way to have it run before manual rebuilds - otherwise adding an extension won't have an immediate effect.

simpson: That's less what I meant, just that it may not be worth the burden of updating tons of packages manually that have their own package management already. I was thinkin of something like what R uses to automate the process.
<nh2>
clever: I'm not quite sure where I have to stick the thing though, how I can turn my one haskell package into something akin to pkgsCross.musl64.haskellPackages.hello
<hyperfekt>
So the idea is that if something goes wrong I have the generated derivations to tell me what happened? My trouble understanding here is that while the build itself may become pure, the two systems as a whole are still equally impure - where is the difference between reading the derivations from a file whose contents come from the network or reading them from the network, except that one of the two persists?
<hyperfekt>
averell: The whole point is for the build to not always be the same, I'm trying to do autoupdating vscode extensions. My reasoning being that if I find something breaks, I can still go ahead and fix the version.
<ottidmes>
clever: I could not make it work with LD_PRELOAD, probably because it itself is doing something similar (its a Core .NET program), with GDB I can make it close the fd to /dev/log or change it to /dev/null, but it restores itself afterwards. (I could of course loop and if its up again close it again, but thats just ugly)

if a derivation isn't deterministic and it gets built on two different machines, could this ever result in this scenario? e.g., if one of the paths was garbage collected and got replaced by the other, or something

<ottidmes>
I guess I will just buy one then, they are not cheap, but not extremely expensive either, not an expense I should spare for something as important as getting access to all my other paswords ;)

any way to supress the output of a program in journalctl? I tried wrapping it: `exec cmd > /dev/null 2>&1`, that did not work, I tried disabling it in the program itself, that did not work, so now I am thinking, surely systemd has something with which you supress or limit the output written to the journal? Any suggestions? Its not a systemd service, so I cannot configure it that way
<srhb>
joko: I'm not surprised. Historically it hasn't actually worked for years. Maybe my commit truly did something to it...
<samueldr>
so something like let arr' = "\${arr[@]}" in '' foo ${arr'} '';
<samueldr>
(if I ever need to do something like that, I end up resorting to making a fragment string holding the desired string, makes it easier to understand the script)
<samueldr>
so you probably want something like "''${arr[@]}"
<pie_>
i guess i want some kind of imperative state watchdog or something :P
<ottidmes>
pie_: environment.systemPackages = with pkgs; [ (hiPrio (writeShBin "nix-env" "echo 'How dare you go back to your imperative ways! Declerative configuration FTW! Use `nix-shell` instead if you want to try something.'")) ];
<pie_>
ottidmes, i was actually hoping theres something to "turn off" nix-env somehow (to prevent accidents like this) but i didnt see anything

I am having a tough time getting ~/.nixpkgs/config.nix and overlays to play well together when overriding packages. I have added the package to ~/.nixpkgs/config.nix and `nix-build <nixpkgs> -A haskell.packages.ghc843.foo` builds that version. But if something in the `overlays` depends on `foo` it does not seem to use the version in ~/.nixpkg/config.nix. I've tried both overrides and extend. Is there some place that documents current bes
<infinisil>
worldofpeace: I have ideas for having something like this for nixpkgs even :o
2018-11-10
<schmittlauch[m]>
clever: nice, why is something essential like this not in the main nixpkgs? Probably the same for virtualbox
<clever>
schmittlauch[m]: line 5 creates the group, lines 6-11 makes the group actually do something useful
<mahakala>
colemickens: hm, been trying to get it work now but fail... I guess I don't understand enough how the nix language work or something...
<sippeangelo>
lassulus, Well right now I use this tool called morph that does some combination of nix-build and copy and activate under the surface, but I had the same problem when just running "nixos-rebuild switch" before. I "solved" this once by running "nix-collect-garbage --delete-old", but this also deletes my entire package cache... There must be SOMETHING I can delete to just make it rebuild that one "append-initrd-secrets" script,
<sippeangelo>
lassulus, I've been trying to get the boot.initrd.network.ssh option to work, but it needs a host key file, and while the "hostECDSAKey" option worked the first time I built, if I change it to something else the build will fail when it still references the old file path which file doesn't exist on disk any more...
<ottidmes>
and could I use buildFHSEnv to achieve the same as I am doing now with a service that does something like: cp -rs --no-preserve=mode $out/share/vscode/extensions/ms-vsliveshare.vsliveshare ~/.vscode/extensions (i.e. copies the complete directory structure and symlink files, so it can write new files in the directories)
<lejonet>
gchristensen: seeing as the ssh connection is dropped, by my desktop, before any auth even is done, I doubt there will be something there, but what logs would that be in? nix-daemon?
<lejonet>
even if the buildmachine conf tells it to explicitly use something else?
<catern>
I want to download something that requires user credentials
<srhb>
(Or something similar)
<colemickens>
and the patch doesn't seem to change much other than some timestamps and maybe an extra transitive dependency, but nothing that seemed like it would have fixed something causing that error.
<colemickens>
I'm seeing if I can whip something up.
<colemickens>
locallycompact: or just something that will "just work" right now?
<colemickens>
so I think the ask i for something like `nix-prefetch-url --unpack` but for however buildRustPackage does cargo256
<kingemp>
init_6, ah I thought you meant something beyond buildFHSUserEnv in nix manual
<ottidmes>
kingemp: so if something has julia as a dependency it will be installed, but julia will not be available in the system environment (e.g. its /bin being on your PATH via a symlink to /run/current-system/sw/bin), only if it is added to environment.systemPackages this will be the case
<kingemp>
ottidmes, thx makes sense. Is there a reason why this isn't needed for most packages? seems like I'm missing something
<kingemp>
does anyone know how I get something in /run/current-system? Do I add a `ln -s` in the installPhase of mkDerivation?

<judson>
The service (iiuc) runs every 3 minutes and writes to ~/shellwarning/git. But I assume that _does_ something?
<lejonet>
so it seems like something unxz'd it
<Dezgeg>
so I guess something unpacked it when it shouldn't have
<Dezgeg>
is it an error message or something then?
<lejonet>
erh, wtf? It seems like it pulls down something completely different than what it is supposed to pull down...
<cransom>
philippD: `command-not-found commandhere` will usually give you something.
<Dezgeg>
full system crash due to e.g. power loss or something?
<samueldr>
I wonder if something changed in `sddm` between 18.03 and 18.09, or its session
<gchristensen>
are you using a DE or something which would make it actually do a thing?
<exarkun22>
cool... something is happening.
<exarkun22>
my best guess right now is that nothing is configured (in systemd) to want the sshd service but I don't have a clue why nixos didn't write some configuration so that something does want it
<ottidmes>
betaboon: could you not do something with pkgs.runCommand convert YAML to Nix, and then import that generated Nix file?
<fooinabar>
I'm trying to compile something that requires both g++ and clang++, but if I add clang to the dependencies g++ fails with: g++: error: unrecognized command line option ‘-stdlib=libstdc++’; did you mean ‘-static-libstdc++’?
<chrisaw>
Knew it was something simple - just couldn't remember what!
<cdepillabout>
Being able to download something is a key functionality of our project, and we would like to test that when running nix-build.
<lewo>
cdepillabout: moreover, as a user, once I have built something, I want to be able to rebuild this thing without having to rely on internet (the binary cache has to be sufficient)
<cdepillabout>
The tests for that package actually do download something from a known-good URL.
<cdepillabout>
lewo, So this is for work. We are writing software that has a feature where it can download stuff for the user (similar to something like git).
<yl[m]>
also nix expresion in a gist or something
<catern>
Unode: nice, but specifically I'm wanting something I can use in build scripts without taking a pointless dep on "which"
2018-11-08
<exarkun22>
is there something like nix-build but which only builds inputs of the target, not the target itself?
<mdash>
overlays are really just a file-organization issue, you don't ever need them to accomplish something in nix
<clever>
fooinabar: ah, then you want something like (llvm.override { enableSharedLibraries = false; }) in your buildInputs
<srhb>
moredhel: I have a shell function for it called gwpi that optionally takes the compiler version too, but yeah, something like that.
<Lisanna>
nixops is doing something insane here
<jgt>
cocreature: it's split into a few different files; I'll make a repo or something. One moment.
<PolarIntersect>
clever: I may have found something. There seems to be no "screen-nvidia[0]" in the xorg.conf it's using
<PolarIntersect>
I feel like maybe something didn't build right, because this seems like a config issue
<acowley>
It's something too search for more info on: a long-standing wrinkle about what nix supports and what hydra allows. I often get wrong what would be IFD, so I might be wrong here, too.

<infinisil>
I'm thinking I might need to reboot to get the ACL's, because it might be used by something now so it can't change it?
<infinisil>
Well a steam controller is something more than just a controller to steam
<rihardsk>
hi, i'm seeing something weird in nixpkgs haskell packages - currently there's no stm package. theres only stm_2_5_0_0 available despite stackage nightly having stm-2.4.5.0
<nDuff>
Is there a way to remove something from scope? I'm accepting an argument I don't want accessible past the let block at the top of my function (think {bar}: let oldBar=bar; in with foo; doSomethingWith bar -- where I want the "bar" to be "foo.bar", not the top-level argument aliased to oldBar)
<clever>
hyper_ch: oh, you turned on something that overrides the nameservers
<TweyIII>
symphorien, b1000101: Looking at your build output it looks like something went screwy with ofborg's build attempt, rather than the package actually being broken…
<azazel>
I was hoping to find something less...hacky.. my goal is to add the package of a python library (click), but just that package built for the same interpreter used for xonsh, so that I can use it from xonsh scripts
