Fix embedding_wrapper.c for Julia 1.11; also, run CI on 1.11, but skip the incremental=false tests on 1.11

[ufechner7]

Fixes #951

This PR does the following:

1. Fix embedding_wrapper.c
2. Start running CI on Julia 1.11.

Note: for now, we skip the incremental=false tests on Julia 1.11 due to #976.

The tests for macOS still fail for reasons that I do not understand. Could some have a look at the error messages who knows macOS better than me?

[PatrickHaecker]

Thanks for doing the PR!

I am a bit puzzled: To my understanding the code change in embedding_wrapper.c should not have any influence on Julia <= 1.10.
Has it really worked before your PR or is the CI failing on macOS a different issue independent of the 1.11 change?

[ufechner7]

CI fails since May 2023, since this commit: 33428b2 Would still be nice to understand and fix the CI failures.

[PatrickHaecker]

Yes, that would be nice. But I suggest that we track that in a different topic.

`$(get_julia_cmd()) --sysimage=$sysimage -e 'using Pkg; Pkg.precompile()'`

probably has a non-zero return value when run, but without access to a macOS Julia installation that is indeed hard to impossible to debug.

[ufechner7]

I created a separate issue for the CI failures on Mac: #955

@IanButterworth It looks like you modified this file most recently. Would you be able to review this PR?

[topolarity]

I can't help bring up PackageCompiler on 1.11 in general, but I can sign off on this change @DilumAluthge

[DilumAluthge]

Thanks @topolarity!

The Julia 1.11 CI seems to be failing on all platforms. For example, look at this CI log, which is Julia 1.11, 64-bit, on Linux. (I've removed the verbose listing of all the environment variables in the active process.)

error during bootstrap:

LoadError("/tmp/jl_3Qidyp/sysimage_packagecompiler_bfb1e672-8b81-11ef-3d17-c7f4e932fd41.jl", 57, LoadError("/opt/hostedtoolcache/julia/1.11.0/x64/share/julia/stdlib/v1.11/Pkg/src/Pkg.jl", 3, LoadError("/opt/hostedtoolcache/julia/1.11.0/x64/share/julia/stdlib/v1.11/Pkg/src/precompile.jl", 101, Base.IOError("could not spawn setenv('' a registries/Registry.tar.gz -tgzip registries/Registry.tar,[ ... env vars ...]): permission denied (EACCES)", -13))))

_spawn_primitive at ./process.jl:140

_spawn at ./process.jl:157 [inlined]

@staticfloat To me, it looks like we are hitting this line in Pkg.jl's precompile.jl file:

https://github.com/JuliaLang/Pkg.jl/blob/27c1b1ee5cf15571eb5e54707e812d646ac1dde3/src/precompile.jl#L86-L86

cmd = `$(Pkg.PlatformEngines.exe7z()) a "registries/Registry.tar.gz" -tgzip "registries/Registry.tar"`

But it seems like Pkg.PlatformEngines.exe7z() is returning an empty string?

[DilumAluthge]

I've opened a separate issue for the bug that is causing Julia 1.11 CI to fail here: #976

[DilumAluthge]

Alright, for now, let's skip the incremental=false tests on Julia 1.11.

[DilumAluthge]

Okay, that change (skipping the incremental=false tests on Julia 1.11) seems to have fixed CI.

Once CI has finished running and is all green, I'll merge this PR and make a new release.
