<kandinski>

hey there. i am running nix-serve on one computer and configured it as binary cache on the other computer. i created a secret/shared key file pair and use it via NIX_SECRET_KEY_FILE as an env variable on the server. but somehow the client does not accept it. i am a bit clueless how to debug that. does anybody know?
<angerman>
infinisil: could nix potentially add `__loc` to every symbol ever defined?
<angerman>
infinisil: that way I could just ask for `a.__loc`
zzamboni has quit [Quit: Leaving.]
<infinisil>
angerman: Um, what's the usecase?
<angerman>
and I could figure out the definition site of any symbol I end up having in my hand.
<angerman>
e.g. where does this specific `callPackage` come from?
<angerman>
where does `x` currently in scope come from?
<angerman>
infinisil: so I ended up writing something like: traceShowValWithLocation = attr: x: let pos = builtins.unsafeGetAttrPos attr x; in lib.debug.traceShowValMarked "${pos.file}:${toString pos.line}:${toString pos.column}" x
<infinisil>
Hm yeah, but that's kind of on the meta-nix level, not something the language should provide
<angerman>
but that kind of requires me to know an attribute in `x`, and, as you said this will only work on attr-sets.
<angerman>
infinisil: I would find that quite helpful for debugging.
<infinisil>
This is something a nix debugger or language analyzer could provide
<infinisil>
Or IDE's
<angerman>
well, IDE's would probably make use of it, I would imagine.
<LnL>
tfc[m]: don't know about NIX_SECRET_KEY_FILE but the daemon needs to be restarted if you add trusted keys
<angerman>
infinisil: and I would need it to work sufficiently close to what `nix-build` ends up instantiating, to figure out why something broke.
<infinisil>
It's probably possible to implement this hackilysh in the language itself, but it really really doesn't belong in the language

new server is up and running with 240G SSD zfs root and 4 TB mirrored zfs data partition :) Amazing how easy it is to replace every disk in your system with NixOS, a quick nixos-install for base system, nixops deploy to get real config and then a really long rsync :)

disasm: I am about to use a similar setup as you and infinisil, but I have just one large disk, and another large disk on a remote machine, so I do not have any raid setup, only remote mirroring. I am just wondering if wasn't better of with smaller disks but doing raid (but that would have my space again, halved by remote, halved by raid)

once you have nixos running as you want to, it's really nice - especially for redeploy... but it takes some pain to get there
Rusty1_ has joined #nixos

hyper_ch2: If you have already learned the tooling, I find it not much different than writing a small log of what you do when installing say Ubuntu or Arch, with the obvious benefits of NixOS being that this log is executable and has to be correct
<infinisil>
ottidmes: mirror with a remote disk???
<infinisil>
Isn't that hellla slow?
<disasm>
hyper_ch2: In my experience, the pain is really only for desktop systems. Deploying services to a server is a snap to setup quickly and get full monitoring. My old debian server I spent hours installing packages, setting up services, and then when a major security update needed to happen, cross your fingers and pray really hard... Took me about 30 minutes to move all that to nixos and I deploy with random
<disasm>
abandon now :)
<disasm>
ottidmes: by mirror with remote disk, I'm guessing you mean rsync for mirroring and not real-time zfs mirror, right?
<ottidmes>
infinisil: It just copies over the difference at a set time interval, that is not that expensive with zfs or btrfs

szicari has joined #nixos
<infinisil>
minor problems i can think of right now: if a destination was unavailable for longer than your longest retention period on the source, it has to do a full transfer
<infinisil>
And: no support for selecting ssh port
<ottidmes>
infinisil: The latter can be easily worked around with a Host entry in your SSH config, that is what I am doing
<infinisil>
ottidmes: yeah same, but it's not very nice
<ottidmes>
infinisil: The first, well if the server is still down after 2 years, I have bigger problems :P
<infinisil>
Oh another minor problem: You can't do a recursive dataset while ignoring a certain subdataset
justanotheruser has quit [Ping timeout: 264 seconds]

ottidmes: i discovered that with my server that doesn't have a lot of storage, so i retain it max 1 month, and then the ssh host didn't work and i didn't notice for a month
<infinisil>
but yeah it's a minor problem indeed
<infinisil>
overall I'm pretty happy with znapzend
<ottidmes>
infinisil: 2 years is probably to long, but I have 8TB, so only once it really becomes a problem I will lower it
<ottidmes>
infinisil: Yeah, seems to work great in my tests so far

infinisil: if longest retention isn't there anymore, just use bookmarks... I do create bookmarks in my script
<infinisil>
hyper_ch2: Well znapzend apparently doesn't use them, but they would indeed solve this problem
<hyper_ch2>
infinisil: I use them in my scritp that uses auto-snapshot
<infinisil>
hyper_ch2: Do you happen to know how much bigger send/recv's are with bookmarks instead of snapshots?
<hyper_ch2>
infinisil: basically nothing
<infinisil>
So you tested this or just a guess?
<hyper_ch2>
bookmark is just another entry that is based on a snapshot.. it's prabably a few additional bytes of storage used
<hyper_ch2>
you add a bookmark to a snapshot... when the snapshot is gone, the bookmark is still there, zfs still knows what data was written since then
<infinisil>
Yeah i know how bookmarks work
<infinisil>
But the manual mentions that an incremental update from a bookmark does need to transfer more than from a snapshot
<hyper_ch2>
infinisil: easy to test: make a snapshot, make a bookmark.... make another snapshot
<hyper_ch2>
output snapshot->snapshot to file
<hyper_ch2>
output bookmark->snapshot to file
<hyper_ch2>
and compare
<hyper_ch2>
infinisil: can you point that out in the manual?
<infinisil>
Hmm, can't find it in the man page, but I'm sure I read it somewhere
<hyper_ch2>
that's more disk i/o for transversing... not acutally more data being sent
<hyper_ch2>
at least that's how I understand it
<hyper_ch2>
(but then I could add a logic to my tool to first check if the src snapshot is still there and if so use that one, otherwise use the bookmark)
<infinisil>
Ohh yeah sounds like it
<hyper_ch2>
that way you get the best of both worlds

I'd think it would do that automatically

Installing packages to your environment is a simple way to get packages to stay, another is the automatically created result symlink of nix-build, the product will be kept unless you remove the symlink

Another is to manually add a root with the nix-store command, check out the manpage for this and search for "root" in it

Also, do packages installed with `nix-env` stay after a rebuild or are they just wiped?

I'm backing up my home right now. Are there any other folders i should back up?
<ottidmes>
MagnificentPako: I would backup /etc as well, for potential custom configs
<MagnificentPako>
Should I just copy my home back into nixos afterwards or do I selectively pick out the stuff I need?
<infinisil>
MagnificentPako: and /var/lib, very important
<infinisil>
Maybe some other parts of /var too..
<MagnificentPako>
I'm still a bit confused by how nixos works. my home isn't touched by a rebuild, right?
<ottidmes>
MagnificentPako: And of course the usual suspects when changing OSes, all files important to you, and don't forget things like bookmarks if you do not sync them
<infinisil>
Ah yeah, this was just general backup advice, nixos almost doesn't touch any data at all
<infinisil>
It puts pretty much everything in /nix
<ottidmes>
MagnificentPako: No, your home is not touched, other then by some of the nix-* tools, but they only create their own files and directories (config files and such in dotfiles)
<MagnificentPako>
Btw, if I were to use XMonad (might as well move to a fully functional workspace; I'm coming from bspwm though) would I configure it using Nix or a .hs config somewhere in my home?
<MagnificentPako>
infinisil: why should I back up the libs?
<ottidmes>
MagnificentPako: Just using the .hs file somewhere in your home
<MagnificentPako>
(and other parts of /var)
<ottidmes>
MagnificentPako: Probably if you have databases and such and want to keep them around
<infinisil>
MagnificentPako: Well that's just something to back up in general, nix doesn't touch it
<MagnificentPako>
Fortunately I don't have anything like that. I will probably use nixos-in-place for the move so I should keep my stuff in /old-root anyway
<ottidmes>
MagnificentPako: I would recommend keeping bspwm initially, take it one step at a time, going from Arch to NixOS already is a huge leap

MagnificentPako: I am using bspwm on NixOS, so if you have any questions about setting it up, let me know

home-manager is a tool for managing user-environments without the need to run nixos

MagnificentPako: you don't run ssh on all your laptops? :)
<tilpner>
NixOS doesn't manage your home directory. home-manager fills that place
<dylex>
kthnnlg: the nixpkgs way to do it is to have a scope using libs.makeScope and use { a = callPackage ./A.nix {}; b = callPackage ./B.nix {}; }, where your .nix files are functions that take their dependencies as input, like b.nix has { a }: mkDerivation { builtInputs = [a]; }

so I should install over my old system without repartitioning?
<disasm>
MagnificentPako: well, ideally, I'd use subvols using zfs or btrfs

Won't that leave me with a lot of cruft from arch?

foldingcookie: nix-env -iA foo installs it for your user, systemPackages installs it for all

how does nix-collect-garbage interact with the two? it seems like it deleted packages I'd done nix-env -iA on?
<maurer>
It should not
<maurer>
both add garbage collection roots
<foldingcookie>
hmm
<foldingcookie>
strange, I'll have to figure out what's going on
<disasm>
maurer: I'd argue subvols are a huge advantage to zfs/btrfs as well. Being able to not have to logically partition your disk ahead of time, as well as boot multiple OS's from the same partition and share data (like /nix /home) between those systems
<MagnificentPako>
Should I go with the graphical installation CD?
<ottidmes>
MagnificentPako: yeah, you should
<ottidmes>
MagnificentPako: You want to have a graphical environment on you desktop I take it, than you should take the graphical LiveCD
<maurer>
disasm: Yeah, I've done that in the past, but if you just want that you can get by with a quick bind mount and pivot root
<maurer>
then again, I guess employing pivot root might be fancier for someone than configuring zfs or btrfs
<MagnificentPako>
the minimal disc won't allow you to install a WM? :thinking:
<maurer>
MagnificentPako: They both have the same installation power and process
<ottidmes>
MagnificentPako: It will, it just won't come preinstalled
<MagnificentPako>

well, it ships with Plasma so I don't see how that gets me nearer towards bpswm

after you enable unfree, the nix-env -q tool can search for unfree things

MagnificentPako: i suggest you decide how you want to keep your software updated, as well. using mainly configuration.nix gives you the advantage of updating in the background and activating all updates through a reboot. using nix-env -iA results in requiring another step to update your system, as you have to update these packages as well

MagnificentPako: I can think about default setup pulling free driver (nouveau) and it then not supporting your card.
<cx405>
MagnificentPako: you will have to research about installing nvidia proprietary driver. (I have radeon cards, so can't help from there, unfortunately).
<tilpner>
You can try installing a minimal system from TTY, so you can leave the live ISO
<cx405>
MagnificentPako: I can recommend to begin with allowing unfree packages in configuration.nix.
<tilpner>
Then you can try fixing the nvidia issues without having to build your own ISO
<MagnificentPako>
The logs say "screens found. But none have a usable configuration"
<cx405>
tilpner: but you can boot into vesa and disable drm (all free drivers) via kernel option, which would force vesa.
<disasm>
cx405: I think that's an option in the installer boot menu, isn't it?
<MagnificentPako>
I'll check
<cx405>
MagnificentPako: yes, that means no current driver could manage your card. You need to pull nvidia proprietary driver, if nouveau driver doesn't support yours. You can read dmesg about how noveau behaved.
<cx405>
disasm: quite possible to do
<MagnificentPako>
I think it didn't even load noveau
<MagnificentPako>
There is no option for different drivers
<MagnificentPako>
Looks like it won't detect my gpu at all

MagnificentPako: The LiveCD might not contain your particular driver, but if you managed to make it work under Arch, you should be able to make it work on NixOS as well, given the right config, so like suggested, I would first try to have a functional NixOS install without any GUI, and then go from there, tweaking your config until you get it right
<MagnificentPako>
That displays a "vga compatible controller" followed by its name
<cx405>

foobar__ - nixos-rebuild build-vm
<cx405>
foobar__: nixos-rebuild supports test in vm
<foobar__>
tilpner: i.e. something that perhaps even copies my entire homedir such that I can test things in isolation.
<foobar__>
tilpner: it shouldn't modify files in any case.
<foobar__>
It could do so with some overlayfs, but that's it.
<tilpner>
You really don't want your entire homedir inside /nix/store
<foobar__>
tilpner: well, if it's gone after, I wouldn't mind.
<cx405>
tilpner: I asked because I have a problem with it.. It works for 1 channel. But If I add two, it looks like second is ignored.
<ottidmes>
cx405: Overlays make it easier to extend the packages, because instead of one place to override, you have layered overrides, if you check the source, it is just a fold on the list of overlays calling extend (where super is the parent and self allow self referencial definitions)
<coconnor>
yep... yep.. definitely a persistent narinfo cache. Looks like it's caching the old (bad) responses from the substituter

vidbina has joined #nixos

coconnor: nope, that would be bad, because your should see the /nix/store and the db as one, if you remove one, you break the whole

on the plus side they are sqlite dbs...

ryantm: why aren't those simple automated updates automatically merged?
<foobar__>
ryantm: at least, after you have identified yourself to the owner of the project with a passport of some kind, that is.
<ottidmes>
foobar__: Just because it can be automatically detected that there is a version bump does not mean that they keep working, regressions happen
<foobar__>
ottidmes: if a regression happens, upstream should fix that.
<cx405>
tilpner: I am totally ill with virus stuff in the nose and handkerchiefs around, so sorry if I dont respond instantly.
<foobar__>
ottidmes: so, there would just be automation that tells upstream a test case that fails.
<foobar__>
ottidmes: and if upstream doesn't respond for too long, it's just dropped from nixpkgs.
<foobar__>
ottidmes: there is nothing to review about most such changes.
<ottidmes>
foobar__: Not sure if you can actually automatically test that, a build failure, sure, but not whether the semantics are still correct, those kind of bugs, not that most maintainers will test everything truly in depth when bumping a version, but they are likely to at least test it by using it, to some degree
<foobar__>
ottidmes: we could even switch to a model where all bug reports have to be scripts.
<ottidmes>
foobar__: If you mean, they run a script to get in an environment in which the bug can be reproduced, then yeah, that would be awesome, but again, that won't work in general, e.g. GUIs or other applications that require more complex interaction that is not as easy to script
Synthetica has joined #nixos
<foobar__>
ottidmes: all the tooling exists to make GUIs also automatically testable.
<ryantm>
I'm not sure if there is a good definition for simple updates. Even on the simple ones, my scripts sometimes get it wrong.
<foobar__>
ottidmes: that is abstractions like "Press File" exist.
<foobar__>
ottidmes: the only problem with GUIs is that they tend to be less stable.
<foobar__>
ottidmes: (which is why writing a monolithic GUI application is almost always a bad application)
<ottidmes>
foobar__: In theory there is nothing stopping us from having that, I would agree, but I am afraid there will be too many edge cases, e.g. are you able to capture all the particulars that cause the bug in the abstraction of the hardware
<foobar__>
ryantm: what's wrong there? Other than that I see the length of hash being different?
<ryantm>
Hard to tell, isn't it!
<foobar__>
ryantm: I suppose j* fixed the mistake your tool created?
<foobar__>
ryantm: I also see a beta version.
<ryantm>
The problem was the hash was not base32 and the source URL didn't use the version attribute
<ryantm>
So my script accidentally changed the hash format and built the old package.
<foobar__>
ryantm: so, you now have added that check to your script?
<foobar__>
ryantm: this is also terrible: cat $LOG_FILE || true
<foobar__>
ryantm: to be honest, I'd rewrite every single line of your scripts.
<ryantm>
foobar__: Go for it. PRs welcome!
<gchristensen>
foobar__: feel free! ryantm's script has been producing serious value to our community, which is way more important to me than the contents of the script.
<gchristensen>
not sure I'd call || true terrible, || "" a wtf,
<foobar__>
ryantm: I would keep lines 4-7.
<foobar__>
ryantm: anyway, not trying to piss you off, just giving you some feedback. I hope it helps. And if not, I will just not give you feedback in the future.
<coconnor>
progress - removed the stale binary caches entries from the sqlite DB.
<ryantm>
foobar__: I'm happy for feedback and you haven't pissed me off.
<coconnor>
I think that's a bug - I don't think nix should persist narinfo on failed sig verification.
<ryantm>
foobar__: Like I said I don't have much experience with bash.

<Yaniel>
kini, MagnificentPako `glxinfo | grep RENDERER` should tell you which driver it is using at least
<coconnor>
"invalid character in Base64" from nix-serve. Well, at least that narrows it down a lot
<ottidmes>
foobar__: Because why not? Seems still quite on-topic if you ask me. There might be others interested
<MagnificentPako>
I don't even have glxinfo. Damn
<clever>
MagnificentPako: nix-shell -p glxinfo
<boomshroom>
There's also the fact that I'd like more info on why firefox stopped working.
<coconnor>
looks like the secret key file provided to nix-serve is not in the right format. What is the right format?
<ottidmes>
MagnificentPako: I would read your journalctl thoroughly and make sure that the right driver is configured in the configuration nix, I would also try older linux kernels, like 4.9 or even 4.4 (I am on 4.4 because of my GPU)
<boomshroom>
A refresh seemed to fix it.
<clever>
coconnor: mine is in the form of name:base64, with the usual trailing == on the base64

MagnificentPako: are you re-using a home folder that you used on another distro?
<MagnificentPako>
I think i got a bit further
<MagnificentPako>
No, i did a clean install
<coconnor>
ottidmes: this key is generated from that.
<coconnor>
clever: same here.
<coconnor>
the line of code failing is "encode_base64(signString(decode_base64($secretKey), $fingerprint), "");"
<boomshroom>
Never mind.
<MagnificentPako>
Now after logging in I'm stuck at a white screen with the text "Session: none+bspwm"
<coconnor>
I presume it's in the "decode_base64" that is failing, but the stack trace doesn't mention :-
<clever>
coconnor: and where did $secretKey come from?
<coconnor>
:\
<ottidmes>
MagnificentPako: Check your journal again
<clever>
coconnor: yep, line 39 split the string at the :
<MagnificentPako>
Running glxgears gives me "couldn't open display"
<clever>
MagnificentPako: how did you run it?
<MagnificentPako>
ottidmes: i disabled that
<MagnificentPako>
I ran glxgears from a tty
<kini>
glxgears is an X app so that won't work I think
<clever>
MagnificentPako: it has to be ran from a terminal inside the xorg to inherit $DISPLAY
<ottidmes>
MagnificentPako: DISPLAY=:0.0 glxgears
<kini>
oh, if you do have X running somewhere else then setting $DISPLAY would work, yeah
<MagnificentPako>
I have checked the journal and it loaded nvidia
<foobar__>
ryantm: do you think it's reasonable that I got a warning from gchristensen for talking to you?
<ottidmes>
MagnificentPako: But it would normally load the driver before running X, so that does not say anything about whether your X server is running
<joepie91>
foobar__: I'm getting the impression that you're trying to stir up shit here. please don't do that.

justanotheruser has quit [Ping timeout: 256 seconds]

coconnor: yes, it works fine on my machine
<MagnificentPako>
coconnor: that gives me stuff like "direct rendering: yes" and "glx vendor string: NVIDIA Corporation"
<clever>
coconnor: though while checking the key format, i discovered that i have 2 keys for this machine, i need to fix that
<coconnor>
clever: OK. this might be related to a previous bit of weirdness
<ottidmes>
MagnificentPako: I have not idea how to configure its location, I just use the default location
<coconnor>
clever: check the owners. For signing with nix-daemon I needed one owned by root. For nix-serve I needed one owned by nix-serve
<MagnificentPako>
Which is? ~/.config/sxhkd/sxhkdrc?
<coconnor>
I suppose weeker perms (group read) might work but... for secret keys I don't like that haha
<clever>
coconnor: everything works perfectly, and the keys are owned by different users
<clever>
for me
<coconnor>
clever: exactly same content too?
<clever>
different secrets and names
<clever>
i forgot i had a keypair, and made a 2nd keypair
<clever>
so nix daemon and nix-serve are using different keys
<coconnor>
clever: ah ok!
<clever>
that would likely also explain why nix-serve works perfectly, but `nix copy` didnt
<clever>
the daemon key isnt trusted, only the serve key
magnetop` has quit [Ping timeout: 256 seconds]

I've got a linux machine which has at least two globally routable IPv6 addresses (one via VPN, one direct), but each of them is on a different interface. Is there a way to get it to accept SSH connections via both of them? Currently I'm running into the issue that it will always respond to connections via the direct interface, even if the incoming connection is through the VPN, which the router it's connected
<sphalerite>
to directly doesn't like.
<ottidmes>
I tried all those, was annoyed to no end when nano/man and those kind things were not behaving the way they always did for me with my Arch dropdown terminal and now xfce4-terminal on bspwm/NixOS
<sphalerite>
s/linux/nixos/ :)
<gchristensen>
sphalerite: sounds like your routes are mucked up
<clever>
sphalerite: i think you need to check `ip -6 route` and confirm a src is on each route
<clever>
sphalerite: also, mess with ping6 on every possible route, while tcpdumping each IF, to see if the reply is taking the correct path
<sphalerite>
oh so if I just `ip route add default via <vpn gw> src <vpn ip>` it should work?
<clever>
maybe not default
<clever>
hmmm, yeah, i'm not sure
<clever>
try default and see what happens

one thing ive been anoyed by, is that my isp has no v6 support, and the v6 gateway i'm using cant share an ip

<clever>
infinisil: ive also recently helped somebody install nixos onto a newer macbook, and anoyingly, nixos lacks drivers for both the mouse and keyboard

Oh the new huge touchbar with the 3D touch thing?
<infinisil>
Or force touch i think it's called
<clever>
i think its basically an ipod touch that has stolen the place of the F1-F12 keys
<boomshroom>
clever: I've seen the touchbar and it seems really useful for apps that support it, but gimmicky for everything else. I don't imagine there are many apps that support it.
<clever>
boomshroom: i recently discovered that electron has support for it, but i suspect it doesnt carry over to linux on a macbook
zzamboni has joined #nixos
<infinisil>
clever: Ohh that one, ugh
<boomshroom>
I'm only on an Air that doesn't have the touchbar.
<clever>
boomshroom: also, in theory, the touchbar can run even with the main cpu shutdown, so you could potentially get things like email notifications
<infinisil>
I personally hate the keys up there, because i can't use them without looking down
<clever>
yeah, i need to feel the shape of keys to push them
<Yaniel>
boomshroom: it's pretty gimmicky even for stuff that supports it tbh
<infinisil>
I plan on making a keyboard layout with lots of smart switches to do everything from a couple rows
<Yaniel>
clever: yeah that would be actualyl useful, but is against apple's rules
<infinisil>
the linux xkb keyboard configuration is helllaa powerful (but complicated too)
<Yaniel>
they explicitly disallow using it as a display AFAIK
<clever>
Yaniel: it would also rely on the touchbar being able to access the wifi hardware directly, i dont know how the motherboard is wired up
<infinisil>
system76 was also in my consideration, but they seem more power focused (and GPU, which i don't need), and less for privacy and security
<clever>
infinisil: the intel ME is disabled on my processor, and there is no GPU option for this model
<infinisil>
Ah nice
<infinisil>
Lol
<clever>
infinisil: oddly, there is a noticable void where a gpu would fit: https://imgur.com/a/hMY9A
<clever>
infinisil: but there is no gpu choice on the site
<clever>
so this motherboard&case may also be used in models other then the "kudu" that have a gpu option
<infinisil>
Lol, system76's website uses a certificate that isn't trusted on my machine, getting a big warning screen
<[Leary]>
infinisil: I've found it's actually pretty easy to tell xkb to spit out the working config, modify it (pretty much just following the format) then load it back in. The real problem with the xkb approach is that unlike the equivalent internal keyboard firmware, applications can decide to ignore it.
<ottidmes>
I did not find this intuitive: nix ping-store --store ssh://mac1, why the --store, or is --store more general or something? (not that familiar yet with nix 2.0)

in the 701 case, you can turn it on/off from software under /sys

[Leary]: Yeah, keycode versus key symbol, i hate that issue

It only complains about the module not existing
<clever>
coconnor: this is a 2 year old change, but that would explain the problem
<MagnificentPako>
So i assume I'm overwriting, not appending
<clever>
coconnor: so the api of the perl helpers was likely changed in a way that breaks nix-serve
<MagnificentPako>
Is there some = equivalent that appends?
<ottidmes>
MagnificentPako: It already appends, just check the generated file, it should be appending if the type of the option is lines
<coconnor>
clever: looks like it. With the double base64 encoded key I'm now able to query nix-serve and received narinfo with signatures
<MagnificentPako>
I'm rebuilding with exportConfig set to true right now

144hz I don't know for sure, but swapping them can be handled using xrandr, autorandr or possibly the nixos configuration services.xserver.xrandrHeads

I'm trying to make a derivation for https://github.com/mujx/nheko, but I'm running into an issue where the build process tries downloading a dependency with git. What's the recommended method of doing this?
<clever>
that replaces configuration.nix with a file that throws an error, so you cant nixos-rebuild
maximiliantagher has joined #nixos
<ottidmes>
clever: Hah! I found that one on someone else's config as well, copied it, but have not yet used it yet, because I kinda want to still be able to rebuild it locally as well
<maurer>
clever: btw, since you seem to use nixops a bunch, do you have a solution for managing the nixops state file?
eliaslfox has quit [Ping timeout: 264 seconds]
<clever>
any time you do that, nixops will loose access
<clever>
maurer: currently none
<maurer>
e.g. backups, dealing with corruption, etc
<maurer>
ok
<clever>
all of my personal nixops stuff is with the none backend
<clever>
so even if the state is lost, i can just create a new deployment with the same .nix files, and it will connect to the same machines
eliaslfox has joined #nixos
<ottidmes>
clever: But if I setup the keys correctly, will it still lose access every time?
<clever>
ottidmes: you will need to dig the nixops key out of /etc/sshd/authorized_keys.d/root and then manualy give it access
<clever>
and each backend handles the keypairs differently

ec2 has its own fun corner cases to be aware of

<ottidmes>
clever: But I understood that nixops is great for managing a fixed set of machines, but less so for having a flexible network of machines that need to dynamically scale
<clever>
Slabity: you may need to chmod -R +w the src after you copy it in
<clever>
ottidmes: yeah, it starts to have trouble when you get to 100 machines in a single deployment
<Slabity>
clever: Looks like it still tries to access the git repo: `fatal: unable to access 'https://github.com/mujx/matrix-structs/': SSL certificate problem: unable to get local issuer certificate`
<ottidmes>
clever: Yeah, that is a limitation of how configurations are loaded, but I mean more, the nature of the tool, nixops has a static view of the world, while things like kubernetes are more dynamic (tailor to a different use case, sure)
<clever>
Slabity: you may also need to patch the build scripts to not do that

and use the full path to build.drv?

Too bad that it does not work at all as I hoped.

sphalerite: Or for any software I run to escalate its privileges, which is what I'd be more worried about
<sphalerite>
timokau[m]: if it's trying that hard, I count that as "a malicious user who's logged in as you" ;)

sphalerite: True, its pretty paranoid
<sphalerite>
timokau[m]: and if it's that malicious it's a lot more likely to go with more general techniques like snooping keypresses through X11, looking for active sudo cookies in tmux sessions, stuff like that
<sphalerite>
so from a security standpoint I personally wouldn't worry about adding myself to trusted-users
<timokau[m]>
sphalerite: I know its pretty unlikely, but even though local security already is a sieve I'd rather not poke any more holes in it ;)
<sphalerite>
¯\_(ツ)_/¯ up to you of course
<timokau[m]>
Instead I hope more and more holes will be fixed by wayland etc
<timokau[m]>
sphalerite: Thanks for your advice in any case :)
<sphalerite>
wayland isn't going to stop malware running as your user, it can still ptrace your compositor or whatever to log keys
<Lisanna>
omg my build is using 50GB of RAM
<sphalerite>
Lisanna: nice.
<Lisanna>
why doesn't nix have ways to limit this ):
<Lisanna>
it's not even a build running on the local machine... it's a remote build
<symphorien>
You can limit the memory of the cgroup of the daemon with systemd I think
<Lisanna>
but if it's going to take 50GB to build it remotely... what's the point?
<kini>
it's a remote build and it's using 50GB of RAM on the local machine? that's bizarre...
<Lisanna>
I mean, I'm dealing with large files... it's a 10GB disk image, and it goes through multiple stages of processing,
<Lisanna>
...so I guess it's trying to pre-allocate all of the space it will need to hold all of the build products in memory at once?
<clever>
Lisanna: nix has to convert the entire storepath into a single std::string and copy it once or twice
<MichaelRaskin>
Ah, that's the nix copy bug of loading too much stuff into RAM
<kini>
lol oh no
<clever>
Lisanna: it will use less ram once its done transfering the file
<Lisanna>
...well I only actually have 32 GB
<clever>
swap helps
<Lisanna>
yeah... but the rest of my system is dead slow now
<clever>
why are the store files 10gig in size?
<Lisanna>
symphorien that sounds like a good suggestion... will it be limited to using swap after it crosses its threshold then?
<Lisanna>
clever it's a disk image
<clever>
ah
<kini>
btw MichaelRaskin since you're around, is there some place where common lisp stuff on nix/nixos is documented? I don't see anything in the nixpkgs manual but maybe I should be looking somewhere else?
<symphorien>
Lisanna: see man systemd.resource-control
<Lisanna>
cool, thank you!
<symphorien>
There is an option for swap and one for memory
<symphorien>
Never used it though
<kini>
(I understand if it's still too experimental to be documented, just thought I'd ask in case I'm missing something)
<Lisanna>
OK, I'll look into it... MichaelRaskin is there an issue open that's tracking the bug?
<Lisanna>
(other than mine, which hasn't really had any activity on it)
<MichaelRaskin>
kini: no, not really documented anywhere, and yes, it is always in a bit of flux
<kini>
I see, thanks :)
<MichaelRaskin>
kini: you could source *-path-config.sh from the packages in question, then use common-lisp.sh from clwrapper package
<Lisanna>
ugh... I'm going ot turn into one of those people that builds from master
<coconnor>
join us - the fires are warm!
<MP2E>
^^ :D
athan_ is now known as athan
<kini>
MichaelRaskin: thanks for the hint, I'll see if I can figure it out...
<MichaelRaskin>
kini: on the bright side, this is close to what the builds are doing
<kini>
the builds of what?
<MichaelRaskin>
For a single package, there is always the launcher script that does the magic
<MichaelRaskin>
Builds of lisp packages
<MichaelRaskin>
You can also cheat by looking at the existing definitions, creating a package with no source but necessary dependencies, and using its launcher script
jrolfs_ has joined #nixos

I'm not sure what you think I'm trying to do -- are you telling me how to launch a common lisp which has access to a certain list of packages?
<kini>
Sorry, I'm actually quite a beginner at common lisp, haha... I am coming from ACL2 which is like a sanitized subset of common lisp so I'm missing a lot of pieces of knowledge I think
<kini>
At the moment, I was trying to accomplish the small task of getting (cffi:load-foreign-library "libssl.so.1.0.2k") to succeed
<MichaelRaskin>
kini: yes… because what else do you want to extract from the infrastructure? Well, unless you try to create new Lisp packages.
jrolfs has quit [Ping timeout: 276 seconds]
<kini>
Eventually I would like to package some more systems which exist in quicklisp but not in nixpkgs, because ACL2 uses them
<MichaelRaskin>
kini: either set LD_LIBRARY_PATH, or look what cl+ssl (cl_plus)
<MichaelRaskin>
(cl_plus_ssl) package ;launcher script does
<MichaelRaskin>
I think we have acl2 packaged separately
<kini>
yes, but that package was pretty broken -- I "fixed" it a few months ago but that was only for the core system, not the included libraries, which have more dependencies
<MichaelRaskin>
We have the converter script to extract data form Quicklisp and create matching packages… for simple cases making it work is simple…
<kini>
so I'm slowly working on getting the libraries to build as well under nix
<MichaelRaskin>
Ah
sanscoeur has quit [Ping timeout: 276 seconds]
<MichaelRaskin>
Yeah, it probably fell behind at some point…
<kini>
for example the core system doesn't depend on any external C libraries but there are ACL2 libraries which depend on SSL and some other quicklisp stuff
<bsima>
how long does it take for the ACME certs to arrive? I thought they get acquired when the systemd service starts up

I'm trying to install haskell's ghc-mod with the command nix-env -iA nixpkgs.haskellPackages.ghc-mod and got the following error: https://pastebin.com/EzS4u8DQ. I tried to rebuild the system and to update the channel, what should I do?

well I'm really happy that Nix's memory usage is being looked at. I've struggled with nix copy using too much memory for a long time now

is there a builder for nix that I can pass the raw github source into and get out a working Nix package?
<bsima>
Lisanna: `fetchFromGitHub`
<Lisanna>
err, no
<Lisanna>
sorry, I mean, something that will build Nix if I give it a fetchFromGitHub
<coconnor>
Lisanna: you could try overriding hte src attribute of the current nixUnstable package
<Lisanna>
oh, nixUnstable used to build and fetch from git
<coconnor>
Lisanna: overriding src with a fetchgit will still work. The result is sufficient
<Sonarpulse>
Lisanna: I was thinking of populating that via users.users.<other-user>.buildSshPubKey or something
<Sonarpulse>
but perhaps that's just overengineering
<Lisanna>
Sonarpulse that's exactly what you should do, except, use the actual attribute :)
<Lisanna>
coconnor I already tried that. the "nix" package does not normally have the necessary buildInputs to build from a raw git checkout.
John882 has quit [Ping timeout: 276 seconds]
<Lisanna>
ugh... there's a "fromGit" option in Nix's builder, but it's not exposed
<Lisanna>
that's not helpful at all ):
<Sonarpulse>
Lisanna: err i mean that like users.users.foo.buildSshPubKey and users.users.bar.buildSshPubKey would be aggregated in users.users.build-client.openssh.authorizedKeys.keys
<Sonarpulse>
but nevermind, its an overengineered idea
<Sonarpulse>
best not to exploit how anything can effect anything

<Lisanna>
coconnor okay thank god, I was not looking forward to copying nix/default.nix into my local tree :/
<coconnor>
great potatoes.. taking a while to build.
ashgillman has joined #nixos
<Lisanna>
coconnor does your overlay use nixUnstable.overrideAttrs? 'cause that approach won't work for me, because I'm on a newer version of nixpkgs that has nixUnstable set to just "nix", meaning it won't have the right builder for building from git

there is no "withGit", there's a fromGit, but I already tried that and it had the same problem
