I'm trying to package a Python application which doesn't use the standard Python build framework. I'm having trouble getting it to set PYTHONPATH appropriately at runtime. I tried adding wrapProgram $prog --prefix PYTHONPATH : "$(toPythonPath "${python36Packages.pyqt5}")" in postFixup, and that's allowing it to find PyQt5, but not the recursive dependencies thereof. Is there a recipe for this somewhere?

Hey, could use some advice.
<Lisanna>
I'm working on trying to get Intel Parallel Studio into nixpkgs, but looks like it's going to be an uphill fight the whole way. Its installer program unpacks things and tries to immediately run them, but the binaries need to have their interpreter changed in order to run. Is using buildFHSChrootEnv my best bet here?
asuryawanshi has joined #nixos
<gchristensen>
hmm no place to squeeze a patchshebangs in?
<Lisanna>
sorry, binary interpreter :)
<Lisanna>
it's unpackign ELFs and executing them
<Lisanna>
and the thing that does the unpacking is itself a binary
<Lisanna>
so no patching
<dfranke>
gross
<gchristensen>
ouch
<Lisanna>
yep ):
<dfranke>
alright, looks like I've solved my Python dependency problem. Build a python environment using pkgs.python36.withPackages and then give the environment as a build input.
<gchristensen>
Lisanna: and you're _sure_ there is no option to unpack then stop?

well, there's about 187 RPMs in here, and a number of other strange packages that look like some weird mutant cross between XML, bash scripts, and some kind of binary, which I think is responsible for driving the installer / TUI interface renderer
<gchristensen>
oh my word
<Lisanna>
I'm thinking I might have more luck with buildFHSChrootEnv
<Lisanna>

<jeaye>
Has the problem of installing software for each user, declaratively, from configuration.nix been solved?
<jeaye>
Every per-user approach I've seen has relied on some imperative steps, I think, beyond `nixos-rebuild switch`.
<jeaye>
I don't really need users to add their own packages, so I'm fine with it being in configuration.nix, but I don't want all of the packages to be global.
<jeaye>
Ideally having `nixos-rebuild switch` also build the packages in each user's `~/.nixpkgs/config.nix` or something would do the trick. I don't think an activation script is a good solution to that.

I use unetbootin when I also want the remaining space to use simply to transfer files

I can get it to boot via the iso loopback, but it fails to mount the root device properly, not sure what that should be in the case of a loopback iso

Hmm, is the label missing perhaps?
asuryawanshi has quit [(Ping timeout: 268 seconds)]
<ottidmes>
Well, what I tried was the partition that held the iso, but I understand how that won't work, since it should point to the root of the installer partition, which you get with dd because it also copies the partition table, but with a loopback iso, you just mount the contents as far as I understand, so I am not quite sure what the root should be
<ottidmes>
the iso itself?
<srhb>
Normally it would be the label of the root partition yeah
<srhb>
If the loopback mount exposes that, I would use it
<srhb>
As in root=LABEL=labelofdevice

I think it might be cleaner to generate the entire thing with the iso utilities in nixpkgs.

It should be relatively simple to embed the other installers like memtest is.

And then you get all the nix goodies for configuring grub.

(Simple in theory, if you haven't touched the infrastructure before it may be a bit daunting)

Mic92: thanks, I have bookmarked your nix config for home. I keep it for learning nix, for the moment what I read is not straightforward for me.
<stphrolland>
orivej: fair enough... and what other advantages for nixUnstable, not counting nix search ? The main advantage for you.
<catern>
hmmmm
<catern>
maybe this is overreaching and over-applying "Nix solves everything!"
<catern>
but I see all this monorepo vs many repos talk on hacker news, and I wonder... isn't "a good package manager" the traditional solution to managing many repositories/many projects?
<orivej>
stphrolland: at the moment I occasionally use `nix` for `nix edit`, `nox` for search, `nix-repl` for repl, and Nix 1.11 for everything else, but I'm ready to switch. `nix build` is pretty
<LnL>
1.12 still has the old commands

hmm

<catern>
I am still wondering how to depend on binaries using absolute paths in Python
<catern>
so I don't have to put them in propagatedBuildInputs, but rather they just automatically get picked up by the dep scanning
<catern>
should I make a build process for my python code, I guess?
<vcunat>
the scanning done by nix is only for references that the build process makes somehow
<vcunat>
(but that part may be automatizable for some languages)
<catern>
yes, so what's an appropriate way to add a Python build process?
<catern>
what do you mean by "that part"?
<catern>
(currently the "build process" just runs setuptools stuff which doesn't actually do anything substantial... hmm wait maybe I should have setuptools do the baking-in of paths, somehow?)
<vcunat>
I don't know much about our python packaging, so better not trust me on that point
<catern>
I am aware, that is why I said "so I don't have to put them in propagatedBuildInputs" :)
<catern>
which, is not a huge annoyance, but, it's a minor benefit to have the build process actually bake in the PATHs, so Python can be treated normally instead of using propBuildIn
<FRidh>
catern: typically you would have to patch the code to hardcode the paths. In certain cases it is possible to creete wrappers
<catern>
FRidh: right, this is my own library though, so I can do whatever I want. including, for example, creating a "config.py" (akin to config.h) which is created by setuptools
<catern>
FRidh: what's your thought on the most idiomatic way with setuptools+Nix to hardcode the paths?
<catern>
one which would be nicely portable to other distributions :)
asuryawanshi has quit [(Remote host closed the connection)]

<Acou_Bass>
i feel like I've had this issue before but can't put my finger on it... when i do anixos rebuild switch, it either fails to restart all the systemd units or completely hangs when i do the command, and so networkmanager goes off until i restart... anyone know where to begin looking to fix that? xD
<FRidh>
catern: in my opinion, if python packages depend on external executables, then they should have somewhere MYPROGRAM = "program" so that it is easily patchable
<catern>
FRidh: hmm, so you do promote patching as the correct way to do it? or, I guess the easiest way would be a locations_of_external_executables.py that can be wholly replaced with a Nix-derived thing?
<FRidh>
catern: it is the only solution for scripts
<grw>
why wouldnt you just use PATH and eg shutil.which()?
<catern>
FRidh: yeah, but this is a library, my own library, so I can do whatever I want
<FRidh>
catern: still
<catern>
grw: PATH is unnecessary when you have Nix :)
<sphalerite>
grw: because even if it's a hard dependency it isn't encoded well and it won't get pulled in by nix
Dr8128 has quit [(Ping timeout: 255 seconds)]
<sphalerite>
if it's a soft dependency that makes sense, but if it's required for the library to function you shouldn't leave it up to the user to install it
<FRidh>
won't work with modules where you cannot wrap any executable
<grw>
isnt that what propogatedBuildInputs does?

Itkovian has quit [(Quit: Textual IRC Client signing off)]
<catern>
¯\_(ツ)_/¯ i'm really looking for something that is more obviously the correct solution than "expert says sure, why not"
<FRidh>
catern: the correct solution is to do a substitution in order to hardcode a path. There is just no other otion
<clever>
tep
<clever>
yep*
<catern>
hmm, okay, fair enough, at least that way there's no weird logic or setup in Python code, all the weirdness is in the Nix package
amfl has quit [(Read error: Connection reset by peer)]
<catern>
though, wait a second! what about when I want to run the program under nix-shell?
bfrog has joined #nixos
<clever>
nix-shell will create a build-time env, and obey propogatedBuildInputs
<catern>
I don't think substitution is fully general - it requires actually running the Nix builder, before you run the stuff
<catern>
clever: sure but nix-shell won't patch files for you
<clever>
correct
amfl has joined #nixos
<catern>
this again suggests that the way to do it is, to do it in setup.py
<catern>
because that way it can be auto-done on setup.py develop which is run by nix-shell in a Python project
asuryawanshi has joined #nixos
Itkovian has joined #nixos
<FRidh>
If you have a Python package, you first build it, and then you can use it with nix-shell -> it ispatched
<catern>
right but I want to hack on it in-place under nix-shell
<datakurre>
catern: I did miss what does not work for you under nix-shell for a developed Python package currently? Would you mind to repeat :)
<catern>
using native executable deps not through PATH
<datakurre>
catern: You mean a non-python dependency in package's propagatedBuildInputs?
<datakurre>
catern: Sorry, I did not get that. "native executables"?
<FRidh>
catern: so you're using "editable" mode then
<datakurre>
I've been working a lot with my Python development setup for Nix lately, so I'm interested, if I have missed something.
<catern>
FRidh: well, not in any serious way
<catern>
that's just a useful hook I could use to set up the executable deps

Hello.

How could I debug an error like this? `variable $src or $srcs should point to the source`

I'm still hoping that I'll be able to build a proper nixos image
<bgamari>
but I'm exploring the debian option as a fallback
<manveru>
dupndrop2: apart from that, $PATH won't change, you have to actively make sure you're looking up the path via nix-executable-find or nix-shell-command
<clever>
bgamari: nixos also has expressions to auto-generate an entire disk image with nixos already on it
<bgamari>
right
<bgamari>
I've been playing around with the ARM sd image expression
<bgamari>
unfortunately getting this to play well with cross-compilation has been a challenge
<clever>
bgamari: this one generates a full nixos disk image, with xen, and then boots that xen under qemu
<gchristensen>
shlevy: sorry for the incomplete first one
<manveru>
btw, i finally got calamares to build :D
<bgamari>
wow
<dupndrop2>
manveru: ok, but say i'll get this to work, spacemacses' command aliases will keep using the python from the global system. if i understand correctly what it does, i'm not sure
<manveru>
dupndrop2: yes, so you need to configure your python package to use your lookup instead
<manveru>
dupndrop2: one example is the flymake they have on the nix-emacs site

(as an example, packages can be present in the store for other packages, without being directly accessible in the PATH)

the short story is that I am trying to know what software I want/need to install without having to do which for all of them. also various guides recomend installing different package, but they are old recomendations, so I may not need to

<marantz>
seems like a lo of effort, but I guess I will too
<gchristensen>
that isn't complete, as some nixos module options add extra things to it depending on what you enable.
<gchristensen>
typically as I find a tool I need, I either add it to systemPackages or use nix-shell to get it
<samueldr>
e.g.: enabling a DE will add most of what you'd call "standard collection of stuff" for that DE
<marantz>
sgtm. thanks guys. btw, I'm using a new lenove t470 and haven't found any real problems yet. although I still haven't tried the camera and fingerprint reader

it is a bit ugly, but running nixos-option environment.systemPackages | less will show you a full list of derivations in your systemPackages (ugly because it doesn't show package names, instead shows nix store paths)

samueldr: joepie91: tailing the drv log might work
<samueldr>
that's what I was thinking, but how do I know which drv log to follow?
<clever>
samueldr: i just look at /tmp/
<sphalerite>
LnL: nope because bzip2

error: build log of derivation ‘/nix/store/iym5kc6jfixvsnjp1g90rpk0vm3l8fd8-nixos-system-nedflanders-18.03.git.3eccd0b.drv’ is not available
<samueldr>
(using nix-store --read-log)
<sphalerite>
it's kind of horrible but you could strace the daemon's child process to see what it's reading in xD
<samueldr>
hydra seems to be able to tail/read bzip2 logs, (but again, hydra might do some heavy listing)
mizu_no_oto has quit [(Quit: ["Textual IRC Client: www.textualapp.com"])]
<sphalerite>
it also doesn't seem to actually write-through the logs…
<Lisanna>
sphalerite: you don't need strace for that, you can just look in /proc and get the list of files it has open
<ottidmes>
joepie91: BTW, I was ati-radeon on my laptop at the time, I looked further into my GPU (HD7870 XT) issue, as it happens, I have one of the very few cards that has not worked with the open source Linux driver since it came out: https://bugs.freedesktop.org/show_bug.cgi?id=60879, so that is why we were unable to get it to work
<clever>
samueldr: when hydra is involved, hydra initiates the ssh links for build slaves
<clever>
samueldr: and hydra then imports the resulting .nar into /nix/store when its done
<clever>
samueldr: but nix doesnt allow importing the logs
<clever>
so hydra stores the logs in a different place
<sphalerite>
Lisanna: that won't necessarily help you get the data if it's a pipe
<sphalerite>
Lisanna: it is indeed a pipe. So the only way AFAIK to intercept the data is with ptrace
<Lisanna>
huh, okay
zzamboni has quit [(Quit: Leaving.)]
<samueldr>
hmm, it seems I can tail the stderr/stdout of the nix-store --realize process
<samueldr>
(through /proc)
<samueldr>
when using a nixos-rebuild --build-host, where will the log be made?
<clever>
on the build host you specified

I am trying to use `git-crypt` and somehow `git` invocations manage to try to run git-crypt binary from non-existing store path :/
<sphalerite>
ok, `tail -f -n +0 /nix/var/log/drvs/xx/xxx….bz2 | bunzip2` works too, but depending on how compressible the data is, compression + buffering might stop anything useful from appearing
zzamboni has joined #nixos
<samueldr>
(assuming this all can work, I'll disable compression if I do anything useful with the knowledge)
<gleber_>
ah, as soon as I posted here, found the culprit - `$REPO/.git/config` has that non-existing path stored

hmmm, the log file for the drv is currently empty, as in 0 bytes bzip2 file

(I don't think it would be THAT compressible, but it possibly is all in ram)

<vcunat>
samueldr: for builds in progress you don't really get anything in the file
<sphalerite>
samueldr: yeah I think it depends largely on how generous glibc is with its buffering. Easiest way to see if anything's going on would probably be strace
<vcunat>
probably due to buffering or something
<sphalerite>
vcunat: you do if there's enough going on
<samueldr>
I'm seeing the log file for the drv, at least
<samueldr>
ah, it's the same (previously) empty file though, I got excited for nothing
<sphalerite>
oh, hm, one issue with that… it intercepts the log completely, i.e. stops it from going to the thing that started the instantiation in the first place
<sphalerite>
which is probably not what you want >.>
<samueldr>
reading the fd stops it from going where it should?
civodul has quit [(Quit: ERC (IRC client for Emacs 25.3.1))]
<sphalerite>
Presumably it then also doesn't go to the build log that you'll later get when trying to read it, so yeah really not ideal
<sphalerite>
so I'd say either use ptrace, or modify nix to allow streaming the log from the daemon in multiple places
<sphalerite>
getting information about in-progress builds would generally be nice
<sphalerite>
AFAIK there's no way to find out which derivation is currently being built either?
<samueldr>
afaik too, that was part of my initial question
patrl has quit [(Quit: WeeChat 1.9.1)]
<sphalerite>
well you could always use gdb on the nix daemon :p
<sphalerite>
it must keep that information somewhere, since it won't try to build the same derivation twice simultaneously
<samueldr>
I'd wager on the .lock files
<sphalerite>
Also, has anyone using tmux ever seen it just stop updating the window width?
<clever>
sphalerite: one anoying issue ive noticed with tmux, is that it always matches the size of the smallest client
<clever>
while screen lets you forcibly resize it
<sphalerite>
clever: I'm fine with that, the problem is it sometimes stops updating the size for the things running inside it even though it updates just fine for itself
<sphalerite>
hm, closing some other panes seems to have fixed it
<sphalerite>
odd
<clever>
it could be the apps inside getting desynced with the size
<sphalerite>
no it's literally reporting the wrong size in response to the ioctl
<sphalerite>
strace suggests it was busy while it was doing that though. Closing a bunch of unrelated panes fixed it, but I still don't know what was the actual culprit
