Malformed Project.toml

[Datseris]

Describe the bug 🐞

I just tried to update my project and I keep getting

ERROR: LinearSolve has a malformed Project.toml, the extension package SparseArrays is not listed in [weakdeps] 

Is this a problem on my side? I wouldn't guess so.

The problem is I can't even report what version of LinearSolve is causing this, because st -m LinearSolve throws this error as well. I did a full delete of my local Manifest.toml file but the problem persists after trying to update again.

That's addressed by #581 but there are some weird CI errors in that PR the last time I checked.

Do you have any advice of what version I should downgrade to to solve the issue for now? Unforutnately I can't run my project anymore and I don't know where to revert to. I've never used LinearSolve directly.

[devmotion]

I'd try LinearSolve@2.39.0.

IIUC this is a Julia bug, and if you upgrade to the patch v1.10.8 it should go away? I don't know what causes the bug so it's not clear how to avoid it.

[devmotion]

The error seems valid, and that check is still present in Pkg#master (but maybe it's masked or not hit due to some different behaviour in 1.10.8 or 1.11): https://github.com/JuliaLang/Pkg.jl/blob/f5174898e9c1814c0963b89c40cffa050451a8b5/src/Operations.jl#L2596-L2599 The problem is that there's a SparseArrays extension (

LinearSolve.jl/Project.toml

Line 63 in 341faad

LinearSolveSparseArraysExt = "SparseArrays"

) but no weak dependency on SparseArrays. This would be fixed by #581.

[ChrisRackauckas]

Should we try hard and weak then? Because that PR looks stuck by a Julia bug 😅

[Datseris]

For what it is worth, updating to Julia 10.8 did fix the issue. Feel free to close!
