OpenSSL version mismatch (3.0 vs 3.5)

[tamasgal]

Our CI jobs which deploy the docs via Documenter.jl using the official Julia Docker image (e.g julia:1.11) started to fail a couple of days ago and I noticed that the problem is a version conflict between the system's OpenSSL version 3.0 and the Git_jll instantiated by Julia, which is pulling OpenSSL_jll version 3.5.

The actual error is:

OpenSSL version mismatch. Built against 300000f0, you have 30500000
fatal: Could not read from remote repository.

Here is a small(ish) repository where you can investigate the details:
https://git.km3net.de/tgal/DocumenterTest.jl (the failing job log is here: https://git.km3net.de/tgal/DocumenterTest.jl/-/jobs/341106)

The problem is obviously a dynamic linking version mismatch caused by git on the system and presumable Git_jll from Julia.

I just realised that Documenter is using LibGit2 v1.6 (cf

Documenter.jl/Project.toml

Line 43 in ced42e5

LibGit2 = "1.6"

) which might be the cause of the mismatch, but I am not sure what's going on.

This whole binary dependency system is a little bit of a dark box to me and spin-off standard library packages in Julia are not making it any better ;)

[tamasgal]

So I think that the release of OpenSSL_jll v3.5 broke things. 3.5 is not compatible with 3.0...

https://github.com/JuliaBinaryWrappers/OpenSSL_jll.jl/releases/tag/OpenSSL-v3.5.0%2B0

[tamasgal]

I found a related issue here: #2357

and here in Git.jl

JuliaVersionControl/Git.jl#51

[tamasgal]

Manually downgrading OpenSSL_jll to v3.0 is a workaround, but this will not last very long for sure:

Pkg.add(name="OpenSSL_jll", version="3.0")

[mortenpi]

I'll close this as a duplicate of #2357, since I'm quite sure it's the same issue. I think we end up linking against the system OpenSSL somehow.

I just realised that Documenter is using LibGit2 v1.6

I'm quite sure this is very much a red herring. First, this is the minimum version (and LibGit2 is a stdlib anyway). But also, we only depend on LibGit2.GITHUB_REGEX.

Documenter.jl/src/utilities/utilities.jl

Line 438 in ced42e5

m = match(LibGit2.GITHUB_REGEX, remote)

[giordano]

I think we end up linking against the system OpenSSL somehow.

That's my feeling as well. I can't reproduce issues locally by installing OpenSSL_jll 3.5, I can fetch a repo with Git.jl without problems. I think there's something else going on.

Just noting down the full log from the OP, in case the CI logs go missing after a while.
