When packaging something for Nixpkgs that doesn't have a version or tags or w/e, does the version become the date the package is created, or the date of the last commit?

Need to hook this up to emacs to do something cool

Hmm, does home-manager or something similar have stuff for systemd user services?
<greghale>
omnipotententity: :) I'd been stuck there for 2 days. Strage how typing a question can provoke you to try something different!
<Ankhers>
Okay, so I checked the service, it was running, but last ran December something. So I restarted it, checked the status again, it appears to have run, but I apparently still have the old cert. Should I just give this a few minutes, or should it have been fairly immediate?
<ToxicFrog>
`systemctl status acme-$domain.timer` to make sure the timer is firing, `systemctl status acme-$domain.service` to see if something is going wrong with the renew.

i made a nixos vm and whenever i try to install something as a user or update the nix channels, the session gets instantly killed
<bhipple>
but I'm not sure if that's something that K8s should really be doing
<bhipple>
As a consumer of something like GKE or the Amazon Kubernetes, though, do you think it's OK?
<bhipple>
Presumably something like the (now defunct) CoreOS and the RedHat initiatives for K8s are getting paid to make it robust/reliable?
<bhipple>
It's *also* possible, depending on the company politics and scale of the deployment, that you might have a better time skipping the OS layer entirely and just deploying application binaries in well-specified Docker containers built by nix and run on something like managed K8s
2020-03-09
<bhipple>
IMO NixOps is the least production-grade of the nix ecosystem tools. Nix and NixPkgs are great, as is NixOS, and feel very robust/production worthy. NixOps works, but you may want to look into something like morph: https://discourse.nixos.org/t/morph-nix-based-deployment-tool/1276

I'm a debian user for about 10 years and just switched to NixOS but there's something I can't figure out. Should I put all my programs into the /etc/nixos/configurations.nix file or should I create a file on my home directory?

side note: I'm only trying to edit the derivation because if you install the `j` package and try to install the IDE afterwards, it won't work because it says it's in a read-only directory, or something like that. If anyone knows a workaround for this, that would be great too

Meaning, it's something at the nixops level

<Orbstheorem>
ottidmes: <doesn't NixOS do something like that automatically>: Yes and no, NixOS (or anything actually) can't do much about your current shell without being overcomplicated, extremely precise and mostly unusable in the general case. The standard linux security model enforces this.
<ottidmes>
Orbstheorem: doesn't NixOS do something like that automatically if you change them in your config and nixos-rebuild switch, never really ran into this, but then again I don't add user groups that often to really notice
<ottidmes>
Orbstheorem: thought it was something like that or maybe having to restart Docker, will try restarting, thanks

zeta_0: If a Nix file foo.nix starts with something like `{ stdenv, cmake }:`, you can build it with `nix-build -E '(import <nixpkgs> {}).callPackage ./foo.nix {}'`

omnipotententit4: i deleted everything and started the elm2nix instructions from scratch before installing unstable.elm2nix(replacing elm2nix), so i have no idea why this mismatch is occurring, isn't nix supposed to automatically fix something like this?

So you have an older version of this file that's being called by a newer version of something.

ok I should read up on nixops, and also making a service in nix. the latter seems to be something you do in your configuration.nix, not just an expression in the nix store. I guess nixops is oriented towards setting up services.

Hey guys, quick question, if I want to share a type (something like types.strMatching "...") between multiple modules in my nixos config, how can I do that? How can I make like a type available to multiple modules? Should I make my own lib-like module which exports these definitions and that I can then import in my modules?
<Shoubit>
Is there a better way to upgrade the single dependency of a package without `.override` or doing something like import <nixpkgs/pkgs/applications/editors/neovim/wrapper.nix> { inherit (pkgs) lib stdenv makeWrapper vimUtils bundlerEnv ruby nodejs nodePackages pythonPackages; python3Packages = mySikPy3Pkgs; }

another approach I've seen is `mkShell (import ./default.nix { shell = true; })` or something to that effect

Make it so that you can write the entire contents of your shell as `mkshell { buildInputs = [ (import ./ci.nix) ]; }` (or something like that)

n00b question: what channel does nixos take its packages from? "nixos", "nixpkgs" or something else?
<niksnut>
you can certainly do something like 'make installcheck' provided you use a writable prefix
<clever>
LnL: i think the nixos installer does something very similar, to bind-mount the host /nix into the guest, and then use the host store as a cache
<Miyu-saki>
Seems like there's something wrong with the 'random' package when you use cabal2nix, idk.
<LnL>
unless it never succeeded for an eval it should return something
<makefu>
for a failed build (nixpkgs.ugarit.x86_64-linux for example) will simply return 404? or am i missing something

but there's nothing to check if both eg. both the unstable channel job as well as something else succeeded

emptyflask: I think you could also make a separate file where you `import ./shell.nix { avr = false; }` or something

In case you're off doing something else by the time this finishes, thank you, infinisil.
<infinisil>
That creates a derivation from a shell.nix that you can `nix-build`, resulting in something that has as runtime dependencies all dependencies of the shell
<infinisil>
lovesegfault: It's not easily possible (though I'd like to do a PR to nixpkgs to allow for that), but you can hack around it with something like this (adjusted, originally from gchristensen): https://paste.infinisil.com/sY8_0nQd70.nix

If a Nix file foo.nix starts with something like `{ stdenv, cmake }:`, you can build it with `nix-build -E '(import <nixpkgs> {}).callPackage ./foo.nix {}'`

2020-03-02
<adisbladis>
energizer`: Any foo2nix tool is _extremely_ likely to end up having different hashes than something manually packaged in nixpkgs.
<emily>
in general hoping that a random derivation you have might match something hydra built just because the underlying source archive is the same is optimistic
<energizer`>
maybe my questions aren't making sense because i'm doing something wrong. i'm using one of the lockfile to nix tools, but that means i have to build stuff manually. these are popular packages, with versions in nixpkgs, so i'm surprised if they've never been built by reputable sources before

Instead, I've removed the override, the env var and gone back to the i915/965 whatever it is, and things got better. (Or I got a kernel update at the same time, or there was a BIOS update in there for something else, who knows).

gccemacs has some pretty huge performance improvements. I'd be interested in helping get it packaged in something like the NUR emacs-overlay :D

if you toss the HOME into a tmpdir in preConfigure or something you might have better luck

that way everything rotates nicely but as soon as something fishy happens the cycle breaks

I think in the end I was able to put this aside and use something else that didn't rely on pycryptodome

"import foo.nix" merely imports the file, so "import foo.nix {something}" calls the function with {something}. `callPackage foo.nix {something}` will import the file but it will also prefill all the arguments which it can import by itself. In your case, `import ./default.nix {inherit pkgs;}` is equivalent to `callPackage ./default.nix {}` since callPackage will fill the "pkgs" attribute himself

fresheyeball: am I allowed to manually override something being marked as broken e.g. can I point directly at hackage or git for a particular package?
<ShaRose>
Anyone know a way I could make a nix function or something so that during nixos deployment it can run an executable with arguments and get the results to a variable via stdout?
<gchristensen>
can I use something like IdentityFile in my ssh config, but specify a specific key in my SSH auth agent (which is provided by GPG)?
<evanjs>
Though I wonder if all that's needed to change that is including "nix" in the initrd-tools :P or something similar
<eyJhb>
How can I nix-shell something from unstable.x?
<worldofpeace>
lovesegfault: weird, I do recall something about things in [Install] not working when using systemd.packages
<worldofpeace>
something in perl, maybe not internal
<lovesegfault>
something is florbed
<worldofpeace>
lovesegfault: the outRef thing I did, and it isn't something from mkDerivation. I just reused it for the makeFlags
<lovesegfault>
So I need something that: a. overrides the module with that from the PR b. overrides the package with that from the pr
<abathur>
when there are separate types with a clear purpose, it's easier to tell that something is out-of-scope in one place, or something isn't covered in another
<lovesegfault>
2. Examples - the easiest way to learn is to see it done, and Nix docs usually spend a lot of time telling you what something does instead of just showing it
<samueldr>
it could be wise to move that README to share/doc/tlp or something
<samueldr>
GrimSleepless: in the body of the PR would have been fine too, e.g. something like "This PR backports #xxxxx"
<colemickens>
clodeindustrie: my usual attack plan when something is broken like that is to update. it usually works out.
<jared-w>
clever: aww yiis, I've got my dumb sandbox thing working. Hoping to write up something nice about that in the next few weeks
2020-02-25
<colemickens>
clodeindustrie: I can try my hand at it and see if we can make a wiki page out of it or something like that :)
<DigitalKiwi>
20:16 gchristensen: I'd recommend giving NixOS a go in a VM or something for the full experience

there's nothing adversarial about asking why we do something that breaks on multiple systems and gratuitously goes against standards, good grief
<simpson>
*On Linux, we *have* a preferred userland already: NixOS. And AFAICT OSX is the *only* problematic kernel, which might have something to do with its publisher~ It's hard to rationalize embracing a vendor that actively is hostile towards us, *especially* when that vendor is a luxury fashion brand.
<__monty__>
abathur: The reasoning there is about the length of the path. Patchelf can't easily patch paths that are shorter then what it needs to substitute or something.
<simpson>
abathur: Oh, sure. Changed to what? Most paths would be longer, and folks asking for this usually want /home/etc or something else non-root; that is, what they're *actually* asking for is Nix installation without root privs.
<simpson>
JonReed: Perhaps FHS envs need to do something to the pkgs, so that bringing your own unprepared pkgs would not work.
<JonReed>
custom pkgs? Will something go wrong?
<dhess>
I tried the localhost trick awhile ago, maybe this is something that's been fixed in more recent versions of Nix?
<dhess>
Here's something that's bothered me for awhile, and it seems I must be missing something obvious. Assume you have some remote builders that you want to take advantage of, and they have the same architecture as your personal machine. How can I get nix-build and friends to use my host *as well as* the remote builders? Right now it seems like if I have any remote builders with the same arch as my personal machine in /etc/nix/machines,
<sphalerite>
fgaz: there was also something about greppability or something why I found placeholders annoying at one point. But they can certainly be useful when an environment variable is impractical.
<sphalerite>
I don't know of an existing way, but maybe you can work something out by looking at how pkgsCross is defined
<__monty__>
Maybe they turned the derivation into something that's not quite a derivation?
<chvp>
ah great, didn't find it when I looked, but I must have missed something
<worldofpeace>
that particular issue had a strange minimal setup, your setup sounds like something I can test in a vm. Will look into it.
<samueldr>
last time someone said something similar, ~15 minutes later their system locked-up :)
<energizer`>
I'm seeing commands available on PATH in `nix-shell` that aren't available in `lorri shell`. Not sure if I'm doing something wrong or misunderstanding lorri.

<AmandaC>
If at all possible, I'd suggest doing something like `foo -v`, `foo --version`, `foo version` if the tool has it; for anything you'd share publically.
<evanjs>
manveru: yeah it works as root on the jenkins box so likely just something with my build env
<evanjs>
I feel like it's something with my build scripts but idk
<clever>
arianvp: if something isnt found in the binary cache, nix wont check again for an hour
<Taneb>
Good, that's my intent (I am using something that is Hydra)
<clever>
Taneb: if your using something like hydra, the fixed-output things wind up in the binary cache, and then it never runs the derivation again, just copies the existing product
<jluttine>
is there something i can do to fix this on my (nixos) server?
<Taneb>
systemd is already running, something like "[OK] Started inform NFS peers of restart" (the machine's in another room)
<CMCDragonkai1>
clever: something to do with fixed point problem?
<CMCDragonkai1>
is there something like this in nix?

<noonien>
i'm building using `buildCommand = ''do something here to create $out''`
<immae>
could you do something like : let your_src = fetchFromGitHub { ... } in { imports = [ "${your_src}/common/pc/laptop" ] } ?
<evanjs>
It's like the store path is removed when stuff still references it, or something?
<latiheis>
is there like, some certs package or something i need?
<emily>
can you do something like __FILE__ in Nix?
<kini>
Does nix set a ulimit or something when building an expression? My build seems to have been killed by the OOM killer but I thought I had enough memory to do the build (from experience running the same build outside nix).
<infinisil>
Oh do I need to set up reverse DNS or something to get v2 to work?
<tilpner>
This happens a lot, fendor_, there seems to be something tempting about the comment telling you to leave it alone
<tilpner>
Yes, but who knows if you broke something prior to this
<lirzhv>
is there a way to add the unstable channel, but with a lower priority or something like that?
<emily>
kini: I think your best bet is to wrap acl2 with something that copies the file to a temporary location and touch(1)s it to the correct time
<gchristensen>
but if you zip on past all the nixpkgs stuff and use fundamental derivations, you can do something else. I saw a neat alternative stdenv at a company which used python.

So, I know there has been discussion on encrypting values in nix files: Has anyone ever looked at something like using hardware serial numbers that require root to use as key material?
<jophish>
that's something to go in
<colemickens>
rivercat: what do you mean? something has to transform dns requests into responses
<drakonis>
you said something about looking for a needle in the haystack?
<bhipple>
As soon as you have two different pkgs, something like `diffoscope` is pretty useful
<bhipple>
It'll always be something like nixbld@localhost
<emily>
is it possible to remove something from environment.systemPackages that a module is adding?
2020-02-21
<simukis_>
I will consider it if I end up having to run `--repeat 10000` or something
<bhipple>
Yeah, you do something like make a change to <low lvl pkg in closure> then do nix-build --option repeat 2 <top pkg in closure> I think
<simukis_>
as in "this and all its dependencies 3 levels deep" or something?
<simukis_>
I’m trying to narrow down onto a reproducibility problem. Are there any tools in nix that would build derivation multiple times and compare output or something?
<Raito_Bezarius>
is there something which prevents options to take arbitrary functions as option parameter?
<Raito_Bezarius>
why don't use something modern like deoplete?
<jared-w>
eyJhb: speaking from personal experince, switch to something eles. Definitely. Language servers are much better now imo
<Thra11>
If a package is broken because a single test is failing, what's the best course of action (I believe the test is invalid): Should I set doCheck = false (overkill IMO), write my own patch to disable the broken test, just be patient and give upstream a chance to fix it (I have reported it), or do something else?
<evanjs>
okay so I'm unsure if it's just taffybar or GDK_PIXBUF or something with the desktop files, but is anybody else getting "Failed to load icon from filepath clion" errors? Maybe in the dock or, well, taffybar :P
