@emma:rory.gayEmma [it/its]in other news, since you maintain dotnet-vmr in nixpkgs: any reason why the build output contains tarballs of the {dotnet,aspnetcore}-runtime packages? i'm not too familiar with building dotnet from source03:27:50
@emma:rory.gayEmma [it/its] (particularly in the lib/Private.SourceBuilt.Artifacts.10.0.100-rc.2.25502.107.linux-x64/ directory) 03:28:44

In reply to @emma:rory.gay
that sounds like pain maintenance wise ^^'
i think ill stick to manually removing it from deps.json for the time being?
It shouldn't be that big of a deal. You could for example set a package source mapping in preConfigure 		04:19:56
@emma:rory.gayEmma [it/its]oh? how would i do that?04:20:40

The vmr package shouldn't really be used directly if that's what you mean. Generally you want the runtime/sdk packages, which should have to references to it 		04:21:05
@emma:rory.gayEmma [it/its]well yeah, im using the sdk package04:21:18
@emma:rory.gayEmma [it/its]i was just surprised by the 2.4GB download of dotnet-vmr ^^'04:21:29
@corngood:corngood.comCorngoodHow is it being referenced? You shouldn't need it for the ask 04:21:59
@corngood:corngood.comCorngood* How is it being referenced? You shouldn't need it for the sdk04:22:07
@emma:rory.gayEmma [it/its]if nix-output-monitor isnt lying to me, it was for dotnetHook04:22:28
@corngood:corngood.comCorngood
In reply to @emma:rory.gay
oh? how would i do that?
Add it to nuget.config for the _nix source (I'm pretty sure that's what it's called. Look at the source mapping docs 		04:23:00
@corngood:corngood.comCorngoodIf anything has runtime deps on vmr that's bad. We should add some asserts for that 04:23:46

@emma:rory.gayEmma [it/its] tht was the dep graph according to nix-output-monitor 04:24:13
@emma:rory.gayEmma [it/its]no clue why it depends on crossgen2 either, i'm not cross-compiling, nor have AOT or similar enabled04:25:13
@emma:rory.gayEmma [it/its]i should note that ive seemingly always had vmr with dotnet1004:27:13
@emma:rory.gayEmma [it/its]* i should note that ive seemingly always had vmr with dotnet-sdk_1004:27:19
@corngood:corngood.comCorngoodThat will need some investigation and a disallowedReference I guess 04:28:54
@corngood:corngood.comCorngoodMaybe you can help me reproduce this. From your log it looks like it's building e.g. Crossgen2. That should be in the binary cache, and as far as I can tell, there's no runtime dependency on VMR.13:57:25
@emma:rory.gayEmma [it/its]if you need something from me, let me know :)18:55:47
@mahmoudk1000:matrix.orgMahmoud joined the room.19:07:17
@corngood:corngood.comCorngoodI just can't reproduce the requirement for vmr to be downloaded. If you can give me a way to reproduce it, that would be great 19:55:18
@emma:rory.gayEmma [it/its]hold on, let me go commit what i have right now21:34:53
@emma:rory.gayEmma [it/its]

nom build git+https://cgit.rory.gay/matrix/LibMatrix.git\#LibMatrix-Federation -L

Corngood this is my current version

21:38:24
@emma:rory.gayEmma [it/its] with the flake being defined as... https://cgit.rory.gay/matrix/LibMatrix.git/tree/flake.nix 21:38:46
@emma:rory.gayEmma [it/its]fwiw, it does just seem to be a build time dependency, not a runtime one?22:00:12

this is what nix why-depends --derivation has to say

22:08:33
@emma:rory.gayEmma [it/its]hm, i was cleaning up and... now i have an infinite recursion issue, yay /s22:54:03
8 Nov 2025
@corngood:corngood.comCorngoodYeah, that's a build time dependency. You shouldn't need to pull it down unless you're building something that directly depends on it.18:33:46
9 Nov 2025
@emma:rory.gayEmma [it/its]then im not sure why i'd need to download it?00:12:42
