<emily> 22:05 <clever> i'm also interested in how nativeBuildsInputs magically rewrites
<clever> emily: not recently, it was linked from an issue explaining things, but the __splice the issue mentioned doesnt exist
<clever> emily: enless, is callPackage adding __splice as it calls things, so you can never see it from `nix repl` ??
<clever> > pkgsCross.raspberryPi.callPackage ({ hello }: hello.__spliced.buildBuild) {}
<{^_^}> "<derivation /nix/store/sg3sw1zdddfkl3hk639asml56xsxw8pf-hello-2.10.drv>"

<clever> aha!
<clever> > (pkgsCross.raspberryPi.callPackage ({ hello }: hello.__spliced.buildBuild) {}).override { hello = glibc; }
<{^_^}> attribute '__spliced' missing, at (string):309:48
<clever> emily: and everything still falls apart, the instant you .override, so you cant actually allow what i wanted
<clever> { buildPackages }: stops you from changing it with .override

<catern> emily: hey, I'm trying to get a pypy36 working for a package (trio) and encountering various broken packages in its deps. I know that trio works on pypy outside Nix; do you have any guidance on how to get packages working with pypy? right now I'm on lazy-object-proxy which is failing with a "is not a supported wheel on this platform."

<arianvp> is it just me or is buildRustPackage broken?
<arianvp> cargoSha256 hash changes every time I rebuild from scratch
<arianvp> seems cargo-vendor is not reproducible
<Profpatsch> arianvp: It has the capability of building a real tree of dependencies, if you convert the lock file to nix expressions
<arianvp> how do I do that?
orivej has joined #nixos-dev
<Profpatsch> arianvp: you would have to write the converter from the Cargo.toml to a nix expression and pass every package to `buildRustPackage` with dependencies in the `dependencies` field
<Profpatsch> buildRustPackage knows how to include rust library dependencies
<Profpatsch> Maybe somebody has written a converter.
<Profpatsch> Ah, crate2nix does it

<infinisil> How does crate2nix compare to ?
<Profpatsch> infinisil: crate2nix uses buildRustCrate from nixpkgs
<Profpatsch> I don’t know about naersk, but iirc it is an attempt at replacing cargo with nix
<Profpatsch> But you can of course inspect it yourself :)

<brotherdust> Hello everyone! Was hoping someone could help me with some problems I'm having creating a Nix package and NixOS module for FRR, a derivative of Quagga. I've been able to successfully compile the package, even install the package. The problem comes with testing the module. As I'm using NixOS on a Hyper-V guest, I'm not sure running the VM-build
<brotherdust> option would work. Without that, I'm not sure how to go about actually testing the module unless I put in a PR to nixpkgs. Any suggestions out there? Much appreciation in advance.

<Ericson2314> yorick: just try it, i would not be surprised if it works now
<yorick> I don't use static libraries, but stripping seems to work fine for cross-compiling
<yorick> and it saves 800MB of closure
<yorick> got my closure from 2.4G to 900M, good enough for today
<Ericson2314> great!

<Ericson2314> weird!
<Ericson2314> do you know why?
<clever> no clue
<Ericson2314> I thought i replaced it with the mfcthread things
<clever> attr name?
<clever> i had to add pthreads, because it failed to link due to missing pthreads
<arianvp> err can somebody explain me the relationship between nixpkgs-unstable and master?
<Ericson2314> clever: look at
<Ericson2314> threadsCross
<clever> 137 ++ optional stdenv.targetPlatform.isWindows libpthreadstubs;
<arianvp> I have a commit that is in master (merged through staging-next) but it doesn't show up in nixpkgs-unstable
<Ericson2314> maybe with mingw is tries to use pthreads rather than native windows stufff
<clever> Ericson2314: this seems to be building
<arianvp> and I dont understand how ?
<clever> arianvp: nixpkgs-unstable only updates when master passes a set of tests
<Ericson2314> you could go make on option to choose between mcfgthredas and pthreads
<arianvp> but it was updates 2 days ago
<samueldr> oh, nix_pkgs_ unstable
<Ericson2314> do a git log -G threadsCross to see when I added it what I did
<arianvp> nixpkgs-unstable has commits from 2 days ago; and my commit is from 9 days ago
<samueldr> (I was going to say "I see 8 days")
<arianvp> it is on master; but not on nixpkgs-unstable which is very fishy
<clever> arianvp: but when was your commit merged?
<samueldr> or, rather, staging merged into master
<arianvp> 9 days ago
<arianvp> whilst other files on nixpkgs-unstable are 2 days old; how .-.
<arianvp> oh wait is this Github mixing up commit message time vs merge time again etc?
<arianvp> but if it's in master; it means staging must've been merged to master right? so why is this commit not in nixpkgs-unstable eventhough it last built 1 day ago?
justanotheruser has quit [Ping timeout: 246 seconds]
<samueldr> when staging-next was last merged into master is probably after that commit
<samueldr> well, I say probably, but it **must** be
<samueldr> and I'm not sure how to see the merge event in this case on github
<arianvp> it was part of this staging-next merge; and the commit is on master too. so nixpkgs-unstable _should_ pick it up; but it isnt
<abathur> is there a person/team that roughly "owns" the UX of the installer process?
<abathur> sorry, the *nix* installer process
<arianvp> and this was 2 days ago; and nixpkgs-unstable is 1 day old
<samueldr> be wary of those relative dats
<samueldr> 1 day and 1 minute could be "1 day ago" or "2 days ago" depending on the implementation
<samueldr> and the channel upgrade counts from when the hydra build has finished
<samueldr> not from when it was started
<samueldr> it was queued at (my timezone since github shows only that) 00:48 on the 6th, merge was 2:22 on th 6th
<samueldr> it missed that eval by ~2 hours
<arianvp> aha
<arianvp> thanks for the digging. Would be nice if these things were 'easier' to trace
