This also needs to include LinearAlgebra.jl back-ports: https://github.com/JuliaLang/LinearAlgebra.jl/issues?q=state%3Aclosed%20label%3A%22backport%201.11%22
Or should those be made into commits here against release-1.11 (where the stdlib hasn't been moved out)?

Or should those be made into commits here against release-1.11 (where the stdlib hasn't been moved out)?

I've been thinking about it and I think the easiest is just to cherry pick these commits onto the julia repo onto either a backports-linearalgebra-1.11 branch or directly to backports-1.11.

@IanButterworth You typo'd the syntax, branches need to be specified using :: https://github.com/JuliaCI/Nanosoldier.jl?tab=readme-ov-file#trigger-syntax. In any case, it shouldn't be required here, as PkgEval uses the merge-base, which should be release-1.10 already.

Ah ok, but this is a 1.11 backports PR. I wanted to check it against 1.10 (because stuff in the blacklist hasn't been tested vs 1.10 because of that bug)

[DilumAluthge]

I don't see the Nanosoldier commit status here, which leads me to believe that either the webhook was never delivered, or that the Nanosoldier server didn't accept the job.

@maleadt please cancel the duplicate run invoked here #56741 (comment) (or let me know how to if I can)

The latest request I did is the correct spec. We want to check against 1.10 state

[maleadt]

please cancel the duplicate run invoked here #56741 (comment) (or let me know how to if I can)

It is currently not possible to cancel Nanosoldier invocations. Only thing I can to is restart the service at a strategic time. I'll check tomorrow when this job starts.

The ScanByte segfault is a package issue and not a problem with Julia 1.11. I've added it to the PkgEval blacklist.
