Emma [it/its]	you'll never guess LOL	19:45:30
Emma [it/its]	Download clipboard.png	19:45:47
Emma [it/its]	(dotnet restore is trying to read the entire nix store, lol)	19:46:02
Corngood	In case it's useful, here's how I debugged it: `nix develop .#modules.nbitcoin.fetch-drv` - fetch-drv is the derivation used by fetch-deps, so this gives you a dev shell where `genericBuild` will do what fetch-deps does before calling nuget-to-json `(set -xe; shopt -s nullglob; genericBuild)` - do a build with tracing turned on, so you can see the `dotnet restore` command where it hangs	19:46:30
Jan Kvapil	It IS useful!	19:47:03
Emma [it/its]	i ended up doing an `strace -f --trace=%file` on the dotnet restore command itself	19:47:22
Jan Kvapil	Good luck with that, .NET	19:47:39
Emma [it/its]	but yeah its hanging because its trying to read your entire nix store due to the csproj being copied as a solo store path	19:47:50
Emma [it/its]	(TIL!)	19:47:59
Emma [it/its]	that sounds like an easy nixpkgs PR, lol	19:48:31
Corngood	Uh I guess it's because the .csproj ends up as a single file in the root of /nix/store/. I wonder what it's looking for exactly	19:48:33
Emma [it/its]	i think its trying to find the sources to build	19:48:43
Emma [it/its]	though interesting that it reads things that arent .cs files	19:48:59
Corngood	ah yeah, that makes sense	19:49:00
Emma [it/its]	yeah, kinda worrying that it would have succeeded on my system with an error lol	19:50:09
Emma [it/its]	(due to the root partition, and hence the nix store, being smaller than the machine's available memory)	19:50:28
Jan Kvapil	The `nix develop .#...` ended up creating a `source` dir with some read-only files. But I guess it's just readonly copy that is safe to nuke ?	19:51:36
Emma [it/its]	i'd guess its a symlink to the nix store, no?	19:52:05
Jan Kvapil	no	19:52:10
Corngood	Oh sorry, I missed a step in the dev shell: `cd $NIX_BUILD_TOP` before running the build.. which just puts you in the /tmp/ dir it creates for the shell	19:52:56
Corngood	so it'll leave some files behind which you can `git clean` or whatever	19:53:16
Corngood	`source/` is definitely part of it, but there might also be other temp dirs	19:54:40
Jan Kvapil	Getting tired, I need to hook to the `buildPhase` and `buildDotnetModule.overrideAttrs` is not working. Is it not possible or bad syntax?	20:03:15
Emma [it/its]	Corngood re: yesterday, do you think you have any suggestions for things to try with the blazor wasm stuff?	20:06:49
Emma [it/its]	i did find https://github.com/dotnet/runtime/blob/main/src/mono/browser/runtime, but that seems to require emscripten	20:20:47
Emma [it/its]	https://dev.azure.com/dnceng/public/_artifacts/feed/dotnet10-transport seems the "nuget" builds moved here	20:31:39
Emma [it/its]	hm, it seems to wipe my nuget.config lol	20:36:49
Emma [it/its]	i did try adding `useAppHost=false` and got this: `/build/nuget.f8zl6P/fallback/microsoft.net.sdk.webassembly.pack/10.0.0/build/Microsoft.NET.Sdk.WebAssembly.Browser.targets(240,5): error WASM0005: Unable to resolve WebAssembly runtime pack version [/build/source/Utilities/Spacebar.AdminApi.TestClient/Spacebar.AdminApi.TestClient.csproj]`	20:39:53
Emma [it/its]	okay, i got closer!	20:50:07
