How do I pass `rng` to `getindex`? 🤨

`getindex` doesn’t use rng, so you don’t have to? I fear we might be talking past each other.

The Mac version is not running on Catalina because of code signing. Are there any plans to provide that?

Make the `rng` a field of the array?

There’s a trick on Catalina for running un-signed Julia (or any other CLI tool, for that matter):

- (attempt) to run `julia` from your terminal
- Dismiss the error dialogs that explain Julia is unsigned and cannot be run
- Open System Preferences → Security & Privacy
- Go to the “General” tab…at the bottom there should be a new notice that says something like “Unsigned application Julia attempted to run blah blah blah” with a button that says something like “Launch Anyway”
- Click that button!

This will tag the Julia binaries as an allowed un-signed binary, so you only have to do it once.

It is a lot easier to just run this:

sudo xattr -r -d com.apple.quarantine /Applications/Julia-1.4.app

But it kind of contradicts a simple drag&drop installer 🙂

I wonder if it would make sense to generate a set of docs for the latest release candidate in a minor version (when applicable, ie before the release) at [Julia Documentation · The Julia Language](https://docs.julialang.org/en/v1/) ? Currently we have docs for 1.3.1 and 1.5-DEV (ie master), and while I know that not much is different in 1.4, it would be nice to have it there already from the RC stage (not a lot will change anyway in the docs).

Just a quick question: Can this be used somehow in GitHub workflows already?  
I tried Julia 1.4.0 there but it does not seem to exist

In general, the random stream for a given seed may change in minor releases of Julia, so tests shouldn’t rely on the exact sequence. See [document random reproducibility policy by stevengj · Pull Request #33350 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/pull/33350)

If you need a particular sequence of numbers for a test, then save the numbers (e.g. as an array literal in your test program). (Or even create a mock RNG type as suggested above.)

Using an RNG from Random123.jl may also be an option, I think Threefry and Philox at least have fixed behaviour.

I’m seeing CI failing on appveyor failing because `Pkg.clone` is [part of the default test script there](https://github.com/JuliaCI/Appveyor.jl/blob/version-1/bin/install.ps1#L66) and because it was removed [as part of the REQUIRE cleanup](https://github.com/JuliaLang/Pkg.jl/commit/b51b4b1db554cc4afc46e435eac6b#diff-fa0f8d7a95cfa5fcc42e790accc462c5L48).

That commit message mentions that is was only there for “legacy CI” but I’m not aware of a newer version of the appveyor configuration. Does anyone have any pointers for me?

I believe it just needs to also look for JuliaProject.toml here: [Appveyor.jl/install.ps1 at 6c48cd21bb8679ab0dd9b2934ec890e2113e69e1 · JuliaCI/Appveyor.jl · GitHub](https://github.com/JuliaCI/Appveyor.jl/blob/6c48cd21bb8679ab0dd9b2934ec890e2113e69e1/bin/install.ps1#L60)

Oooh good catch! I’ll submit a PR.

Not necessarily. Mersenne Twister hasn’t changed either, but we’ve changed how we _use_ the underlying random stream in some cases, e.g. `sprand`.
