Actually the unpacking thing might be a red herring possibly caused by with_context attaching the wrong context to a different error. I removed the ? in https://github.com/JuliaLang/juliaup/blob/20a20b97615eedefc5853d61d5d9b30bcc505b44/src/operations.rs#L48 and now the error is that libjulia-codegen.so.1.12 can't load libLLVM-16jl.so. Last I checked (a day or two ago) I didn't see that locally when manually downloading, unpacking, and using nightly. So still doesn't work but... progress?
Swapping the tar crate for binstall-tar, a fork that fixes https://github.com/alexcrichton/tar-rs/issues/295, fixed the primary failure. The test that fails now is related to pulling versiondb from S3, and there isn't one for FreeBSD there. Perhaps I'll separate out the versiondb changes from this PR so that those can be merged first.
Some to-do items:
- As @davidanthoff and I discussed in Slack, using the binstall-tar crate in place of tar is not ideal since the former seems unmaintained; it reflects tar v0.4.39 with the first commit from https://github.com/alexcrichton/tar-rs/pull/298 applied, but does not include any of the changes made to upstream tar since then. Some options we discussed, which are not necessarily mutually exclusive:
- Make binstall-tar a conditional dependency such that it's used for FreeBSD while tar is used for other platforms.
- If the author of the linked tar PR doesn't respond, make a new PR based on it with conflicts resolved in order to move forward.
- Temporarily maintain our own fork of tar, despite neither David nor I knowing enough about that crate nor the fixes in the linked PR to warrant doing so...
- Use binstall-tar on all platforms (currently implemented in this PR). This means we don't benefit from any updates or fixes in upstream tar.
- Add FreeBSD to the release building setup.
binstall-tar has now been synced with upstream tar (https://github.com/cargo-bins/tar-rs/pull/1) and a v0.4.42 release has been published. IMO it seems reasonable to switch to binstall-tar (currently implemented in this PR) until tar has been updated to include the necessary fixes.
Everything is working now, though I ended up taking a slightly different approach from when I started this. It looks like it might be a long time before the tar-rs PR that would allow us to properly read tarballs produced by BSD tar is merged, if it ever is. In the meantime, we can simply spawn a tar process to do the unpacking. This seems to work just fine.
I think this is finally ready for review, @davidanthoff. It's worth noting up front that I don't actually know Rust so there may be better ways to implement this approach.
Oh, one more question: so this uses the download script and then the self-update option. I'm wondering whether there is also a system package manager on FreeBSD that we could utilize to distribute things? I think in general my hope is that over time we can utilize system package managers as much as possible to get Juliaup onto user's machines, and only use the download script on platforms where there isn't really a compelling story (ahem, Mac...).
There is, the system package manager is called pkg. They don't typically redistribute third party binaries though, preferring to compile things themselves as part of the "ports" system. (Think macOS Homebrew if there was no --cask option.) It also doesn't seem to be very easy to contribute to, nor to monitor for issues. IMO it's worth using download + self-update in the near term and look into adding a port in the future.
Cleaned up my commit mess and rebased on main to make extra sure things continue to work as expected here with the updated dependencies.

Yes, that sounds like a good plan.

So that might work for us, because we can easily have them compile julialauncher and juliaup etc, right?
