this might make it easier to store node modules in the nix store?
<neonfuz>
pretty much rather than npm / yarn creating a node_modules folder, it knows how to pull from a global cache
<neonfuz>
so in nixos terms, could make it pull from the nix store rather than, idk, node2nix or somehow symlinking packages from nix store to node_modules

<ghasshee>
hi, is there any good instrunctions about building haskell environment ?
<ghasshee>
it seems so complicated because haskell allows cabal stack nix ..
<ghasshee>
I can run /run/current..sw/ghci but cannot run stack ghci ...
<ghasshee>
where to start the documentation ?
<ghasshee>
I think the manual is not enough to understand the nix structure ..
<ghasshee>
( I am a minimalist
<sphalerit>
jw358: direct links no, because you need a hash as well
<sphalerit>
jw358: you can use a custom unpackPhase to deal with tarballs with no root dir
<ghasshee>
I always feel like unfamiliar with syntax of nix packages manager .... , is there any thought behind the language ?
<srhb>
ghasshee: It's very lightweight, simple and it's really good at manipulating attrsets, which is the "base unit" of most packages.
<srhb>
ghasshee: I don't know what your background is, but my experience is that most people that come from FP languages absorb the language really quickly, syntax-wise and semantically.
<ghasshee>
fmmmm
<ghasshee>
Indeed , I am just a kid
<ghasshee>
thanks , that fact really encourages me .
<srhb>
ghasshee: Regarding stack: I find it doesn't really work very well with nix
<srhb>
ghasshee: If you use it, you lose most of the advantages of Nix, specifically the binary caches.
<ghasshee>
My philosophy is based on formality and distributed consensus
<srhb>
I have no idea how that relates to the topic at hand.
<ghasshee>
so, building from package, stack ?, seems really nice .
<ghasshee>
Of course I love the binary cache as well

Thanks ... learning nix language will do for me :)

When I set hardware.opengl.package, will packages that take { libGL, ... } as an argument link to the correct thing?
<sphalerite>
tilpner: yes. They will also link to the correct thing when you don't set hardware.opengl.package. :p
<tilpner>
That can't be true
<tilpner>
If I don't set hardware.opengl.package, how could they link to these mali blobs I've never told the package about?
<sphalerite>
tilpner: libGL is glvnd, which loads the right thing from /run/opengl-driver or something like that.
<sphalerite>
not sure of the exact details but that's the basic gist of it.
<tilpner>
I assumed /run/opengl-driver was set according to hardware.opengl.package
<sphalerite>
yes
<tilpner>
So if I don't set hardware.opengl.package to the correct thing, /run/opengl-driver will not be the correct thing, and the package will not link to the correct thing
<tilpner>
And yet you say "They will also link to the correct thing when you don't set hardware.opengl.package". Which part is wrong?
<sphalerite>
the correct thing for them to link to is glvnd, and they link to that regardless of hardware.opengl.package
<tilpner>
Unless you understand "link to the correct thing" to mean "link to glvnd, which is always the correct thing"...
<tilpner>
yeah, that
<sphalerite>
as for which driver gets loaded/runtime-linked, yes, that depends on hardware.opengl.package
<tilpner>
And glvnd then interacts with /run/opengl-driver, which might be the driver we want or not

I have a single user nix installation complaining about "error: opening lock file '/nix/var/nix/db/big-lock': Operation not permitted" -- I own that dir -- any ideas?
<kisik21>
also how to see the why a certain package is being built on a system, assuming I haven't deployed that configuration yet?
<sphalerite>
kisik21: you can use nix-store -q --graph on the system drv to dump the dependency graph then find out from there
<kisik21>
or you can just `grep $drvname /nix/store/*.drv -rl`
<muvlon>
sphalerite, no, they can go through the AP
<muvlon>
lejonet, yes, one subnet
<sphalerite>
muvlon: ah right just not have the AP handle IP
<sphalerite>
kisik21: that's slower and will likely give a bunch of irrelevant results though ;)
<muvlon>
they're already in the same subnet IP-wise (that is, the AP is a DHCP server and gives them the right prefix)
<sphalerite>
muvlon: I think it should allow that by default
<muvlon>
but no packets are coming through :(
<muvlon>
it shouldn't matter, but i tried disabling the built-in firewall

<ottidmes>
kisik21: check out nix-diff if you want to see the differences between two derivations, I used it just now to check why my system rebuild wanted to build firefox from source
<sphalerite>
lejonet: really? How would DHCP work then?
<lejonet>
sphalerite: the layer 2 is unicast, it doesn't matter whats above it
<muvlon>
sooo, should I bite the bullet and enable IP forwarding (and set up a firewall)?
<kisik21>
ottidmes: I'm on ARMv7, there are almost no binary packages for it even in specialized binary caches
<thefloweringash>
hostapd has a flag for this, `ap_isolate`, which should default to allowing frames to pass between associated stations
<lejonet>
muvlon: iirc that is the only way to get what you want to achieve (what I meant with unicast is that its point-to-point, i.e. not the same type of "shared medium" that switches give)
<muvlon>
alright

another nixos-networking question then, if you don't mind
<lejonet>
sphalerite: lol, you want broadcasts? Go to radio :P
<ottidmes>
kisik21: thats just one use case, it just gives you a diff, so if you want to know why its being built (which you asked), that is a great way to answer it
<thefloweringash>
it's been a long time since I was messing with hostapd too, I hope it's still a thing!
<lejonet>
sphalerite: wlan already has too much noise pollution due to active beacons and such :P
<kisik21>
ok
<lejonet>
thefloweringash: I doubt they'd remove such a feature if so :)
<sphalerite>
lejonet: no, mostly just the ability for my devices to communicate locally regardless of whether I'm at home or not
<muvlon>
I also have an ethernet interface on the same box, but it's usually not plugged in - only when updating/fixing stuff
<kisik21>
any way to clean up /nix/store without GCing my half-built system?
<muvlon>
that one is configured as a DHCP client and logically completely separate from wlan0
<sphalerite>
ottidmes: thing with nix-diff is it's haskell, which makes getting it running on ARMv7 Not Fun™
<lejonet>
sphalerite: uh? I fail to see how those 2 connects, that isn't a problem that layer 2 can handle... :P
<muvlon>
so i guess my question is: how do i control dependencies between systemd targets in nixos?
<sphalerite>
lejonet: what I'm imagining is that the devices all associate amongst each other so it doesn't matter if what was previously the AP is in range or not, I can still run syncthing between the devices I have with me
<muvlon>
I'd still like that interface to use dhcpcd, but the networking target should not depend on it

<sphalerite>
ottidmes: etu: nix-collect-garbage conflates deleting old generations with garbage collection. It can be useful, but what we want to avoid in kisik21 's case is a partly built profile (since it's not finished building, it doesn't have a GC root) being GC'd

* sphalerite
is too scaredy to use autoUpgrade
<kisik21>
does service autorestarting work nice on servers? from my experience on using NixOS on desktop I felt that it's more tailored for zero-downtime servers.
<etu>
lejonet: I haven't had to touch my VPS since I upgraded from unstable to 18.09 (before it became stable) and enabled autoUpgrade. It has just worked :-)
<sphalerite>
I wouldn't want to autoUpgrade zero-downtime stuff
<lejonet>
sphalerite: yeah, for some "odd" reason, a lot of people would like to do routerless networking even for wireless :P (as its dead simple with a switch and ethernet cabling, why shouldn't it be for wireless?), sounds good! I should join #nixos-chat.... :P

<sphalerite>
lejonet: I wouldn't enable autoUpgrade *as-is* for zero-downtime stuff, instead doing some sort of magic with two machines running the services and blue-green thingmies.
<sphalerite>
Although maybe I'm taking zero-downtime too literally:D

kisik21: But I wouldn't be brave enough to do autoUpgrades for any production systems for like work or so :)
<kisik21>
Well, NixOS has rollbacks anyway
<etu>
That's correct, but then I have to be there to do the rollback :p
<sphalerite>
sure, but that's not enough to prevent downtime
<etu>
and by default the autoUpgrade is at 04:40. And I'm usually not awake at that time
<sphalerite>
haha
<kisik21>
etu: If system is still available via ssh, nixos-rebuild switch --rollback. If not, well, log in the management console (and for me - enable the TV my RPi is plugged in) and choose another generation in the bootloader
<etu>
kisik21: I use autoUpgrades on my kodi machine, that's lovely. But I don't think it restarts kodi automatically since it's a graphical desktop.

I'm currently struggling with the design of a configuration tree that will in turn add configuration to containers.* and services.nginx.* and I'm trying to separate each configuration "per type". However, appears to be impossible for a submodule to add something in another "branch", how to solve that? I'm trying to find out some existing configuration to study... I don't think it's possible to attach functions to config branches?
<qyliss^work>

i mean, for a function handling configuration in mycompany.sites.<name> (a submodule) to add something to services.nginx.virtualHosts or containers or, if that is impossible, to produce a function that is then attached to mycompany.sites.<name> tree for later use by a global mycompany.sites module
<azazel>
is it more clear now?
<qyliss^work>
Can't you just set `services.nginx.virtualHosts` in that module?
crmlt has quit [Ping timeout: 250 seconds]
<azazel>
so, the submodule for mycompany.sites.<name> contains an enum, a siteType which I would use as an extension point, and then subdivide the configuration of each "type" in it's own module

Is this crazy?

Is there any way to copy an already existing nix path from a binary cache?

(Because nix doesn't have fully reproducible builds?)
<bbarker>
In what way are users in nixos containers related to host users? I seem to recall docker did some kind of UID mapping from container space into high UIDs in host space. But maybe I'm wrong. Are they totally isolated (other than, root, apparently?)

<tathougies>
infinisil: no i have not, but by the sound of it it's what i want. Will that work even if there are references in the nix store?

tathougies: can you clarify your question? Nix will automatically substitute prebuilt binaries when the cache has them available. binary cache substitution working is not dependent upon fully reproducible builds, so something else is going on if it isn't working.

Hi folks, how do I installed octaveFull? nix search octave shows `* nixpkgs.octaveFull (octave)` as an option, but nix-env -i octaveFull doesn't install it. I need octaveFull because it provides the GUI of GNU Octave, or so I believe based on NixOS/nixpkgs#33160.

how should I package a shell script that contains dependencies?

<tathougies>
gchristensen: oh it's working. I'm just curious to see if I can get nix to copy over an already existing derivation output based on the output of the same derivation on another nix store
<tathougies>
nix copy does not work, because it stops once it sees the derivation output already exists
<tathougies>

is either involved host CPU bound?
<Ralith>
might be different types of compression being used, too
<colemickens>
Good point. Shouldn't be CPU bound on either end.
<colemickens>
I'm pushing to Cachix now, but I'll do an informal test here in a second and see if `rsync` and `nix copy` are noticeably different for this particular store path.
<Ralith>
what do you mean by "shouldn't be"?
<colemickens>
shouldn't be, as in my local machine never gets about 20% load and the remote machine is an idle 48 core EPYC machine.

aminechikhaoui: clever: thanks! that should have speed it up a little, although of course the most time is spend in getting the new system out path
<clever>
ottidmes: nix-instantiate can also be used there
<infinisil>
ottidmes: Hehe, how about this: sudo sqlite3 -noheader /nix/var/nix/db/db.sqlite "select path from ValidPaths where path like '/nix/store/nax0kx5jdhf67bz4r6v4z03l1qdsiq3a%'"
<ottidmes>

gchristensen: The NixOS text doesn't really fit there imo, it's really squished and too small

yeah, I'm worried about that too. it is a bit ugly outside of the logo, unfortunately

Damn, I never knew how nice nix-diff looked
<ottidmes>
clever: I thought better make it a function, because I its almost my only use case of nix-diff
<ottidmes>
infinisil: its awesome in how effective it is
<clever>
ottidmes: in the above case, i was moving a machine from one git repo to another, and re-arranging the nix files as i went, and turning it into nixops
<clever>
and i wanted to go over it line to line to make sure no secrets wound up in the public repo, but also it had no real changes

What is the point of nixops export to json if it can't be imported from json?
<clever>
dmj`: it should import just fine
<dmj`>
clever: it doesn't for me, I try nixops import -s /path/to/deployment.json
<dmj`>
and even nixops import without the -s argument
<dmj`>
clever: first error was, "the extension must end with .nixops", which means it's looking for the sqlite database
<dmj`>
that's with the -s flag
<ottidmes>
clever: about better CLI commands, do you have anything better than: nix-store --query --outputs $(nix-instantiate --quiet '<nixpkgs>' -A hello)
<clever>
dmj`: the -s flag tells it where to find the sqlite db
<clever>
your telling it to open the json with sqlite :P
<clever>
dmj`: did you try `nixops import < deployment.json` ?
<dmj`>
clever: right, because there is no option to import json, so I assumed the cli would be intuitive and detect it's json, but it's not
<dmj`>
clever: ok using indirection worked
<dmj`>
clever: how the hell was I supposed to know that
<dmj`>
clever: thank you
<clever>
dmj`: export prints to stdout, import reads from stdin
<dmj`>
clever: makes sense now
<dmj`>
clever: but that is documented nowhere
<clever>
so you could just `ssh remote nixops export -d | nixops import`
<ottidmes>
dmj`: it does say it in the manual: "The state is read from standard input."

(but that is not to say the UX could be improved)
<dmj`>
ottidmes: guess I'm in the wrong here then, its a RTFM situation
<dmj`>
clever: that's pretty nice, but I'm just going to put the state in the repo encrypted for now with git crypt

What is the best way to interrupt a running package build in the background? As these are not done by nixos-rebuild/ home-manager themselves but by the nix-daemon, CTRL+Z doesn't interrupt the builders.

schmittlauch[m]: wouldnt kill always be an option, not sure though what the "best way" is

i saw it without even noticing, and type it the normal way :P

it cant even remember which word it is, lol
