[bug#38546] [Nicolò Balzarotti] [PATCH 00/10] Update julia to 1.3.1, fix precompilation, add HTTP.jl
Sat, 18 Jan 2020 14:42:10 +0100
Ok I had time to look at this again.
1. Package installation can be done both the julia way and the guix way
2. SOURCE_DATE_EPOCH is respected in package precompile timestamp. Other fixes
are needed to get reproducible builds, but for now that means that package
cache is used.
3. This patch adds some first julia package (HTTP.jl and dependencies)
4. Updated julia to 1.3.1 (latest release). It's working great and the
build recipe is simplified a lot. However, some test is failing. The
"interesting" part is that when running tests alone, they are working.
It seems like the problem arise when tests are run on the _same core_
and not on different cores. I opened a issue upstream for this
(https://github.com/JuliaLang/julia/issues/34330), I'll have to look
further on it, but for now if it's fine for me this is ready to be merged.
I'm sending the patch series here.
