nushell: https://book.nushell.sh/en/installation / no on-point issues seen here -- searched for "nushell"

Tried to build nushell from source and it required "nightly" rust. Didn't know how to install that, so I used "cargo install nu"

I expected to see this happen:
Build complete -- the cargo install has worked with other tools.

Instead, this happened:

thread 'rustc' panicked at 'could not initialize thread_rng: All entropy sources failed (permanently unavailable); cause: OS RNG not yet seeded (not ready yet); cause: Resource temporarily unavailable (os error 11)', /cargo/registry/src/github.com-1ecc6299db9ec823/rand-0.6.1/src/rngs/thread.rs:82:17

note: the compiler unexpectedly panicked. this is a bug.

This looks like an issue in the getrandom crate (cc @dhardy @newpavlov).

What distro and hardware are you building on? Can you post the output of uname -a?

That kernel version is missing the getrandom() syscall, so perhaps there's something wrong with the fallback paths in the getrandom crate?

The error report uses Rand v0.6.1 which does not even use the getrandom crate. It would be nice to see if updating nu to rand 0.7 fixes the problem @jonathandturner. We are aware of a potential issue when many new thread-rngs are initialised in a short space of time: rust-random/rand#804 (fixed in recent versions of getrandom).

I don't understand why this issue was reported here, instead of against nu or rand?

@dhardy the compiler is panicking due to its use of rand, not nushell

Not sure how much it would take to update rustc to rand 0.7.0, but updating to 0.6.5 would be easy. @dhardy do you think that could help?

Actually, doing cargo update -p rand:0.6.1 breaks the build. Looks like rand accidentally released a breaking change as a patch release?

@RalfJung that's a known issue; you must update rand_core to at least 0.3.1 at the same time. Unfortunately fixing it now would cause breakage for no_std users IIRC.

The issue with upgrading to rand 0.6.5 is described in rust-random/rand#852
rand_os is no_std crate using libc with default features. Why does it matter?
C library is linked by std or libc without default features leaving rand_os with undefined references when building Rust (and probably some no_std crates), see #61393.
getrandom had the same issue so I updated it in #63806 (I'll update it again tomorrow morning CEST) and this time it worked in local build.

Check-in from the compiler triage meeting:

This is fixed by #63806, correct? I'm going to mark it as P-high but also assign to @mati865 -- thanks for staying on top of that!

@nikomatsakis nikomatsakis added P-high and removed I-nominated labels Aug 29, 2019

rustc 1.37.0 (eae3437df 2019-08-13) probable fix landed only in nightly but you are using stable release.

Hi.
I thought about that afterward, so (after some research) I did this:

$ ./rustup toolchain install nightly

  nightly-x86_64-unknown-linux-gnu installed - rustc 1.39.0-nightly (34e82a7b7 2019-09-10)

info: checking for self-updates

So I checked for the version after install nightly and failed compilation:

$ ./rustc --version
rustc 1.37.0 (eae3437df 2019-08-13)

Where does it put the updated (nightly) compiler? ... cheers, drl

rustc +nightly will call the nightly compiler. rustup override set nightly makes nightly the default for your current directory (and its subdirs).

Hi.
I used rustup default nightly now and I see:

$ rustc --version
rustc 1.39.0-nightly (34e82a7b7 2019-09-10)

Trying the compile again ... cheers, drl

Thanks, it's valuable data.

Guess we gotta get rid of rand < 0.7 from every rustc dependency.

Hi.
After running ``rustup override set nightly`
It finally compiled. Whether it runs or not, we shall see, but this is a giant step in the right direction

This is a pretty big rust code compared to others I have seen (perhaps 6 or so), so good work.

I have no idea how setting the default as I first did differs from the way RalfJung suggested, but his suggestion appeared to be the correct one.

Thanks to all for getting me to this point ... cheers, drl

Can you add a backtrace? rand 0.6.1 is still a dependency for the following crates:

  • miri
  • parking_lot_core (v0.4.0 is used, while the latest version is v0.6)
  • phf_generator (it was updated recently, but new version have not landed on crates.io yet)
  • rls, rls-rustc
  • rustc-workspace-hack
  • tempfile (we need to just update to v3.1.0 here)
  • tokio-threadpool
  • uuid (the update has not yet landed on crates.io)

@newpavlov:
it compiled. Do you still need a backtrace? I might not be able to replicate the problem, but it may be related to how the default was set ... cheers, drl

Overrides are explained in https://github.com/rust-lang/rustup.rs#directory-overrides

I identified parking_lot 0.7.1 and tempfile as rustc dependencies pulling in old rand.

@newpavlov it's true the tools might not work because of the old rand but much more important is to have rustc working.
#64381 should take care of it, I'll see about the tools this or next week (it's hard because upgrade has to be coordinated).

@RalfJung the thing is currently all the tools and

rand = { version = "0.6.1", features = ["i128_support"] }
probably need to be upgraded in single PR. I think duplicated dependencies check will fail otherwise and you'll have to revert rand upgrade but if you can make it though it'd be great.

I'll start with removing unnecessary dependencies from rustc-workspace-hack.

I think duplicated dependencies check will fail otherwise

I don't think so. That check is for the same version of the same crate being compiled multiple times due to different feature flags.

We've had multiple versions of memoffset in our Cargo.lock for quite some time already.

Status update:
I believe #64381 should have fixed this issue for rustc executable.
#64384 removed removed rand dependency from rustc-workspace-hack which should allow tools to upgrade their rand dependency.

@lienke could you try next nightly (it will be released around 2019-09-17 01:00 UTC)?

edit: fixed date

To be fully precise, it'll be released around 1h later than that (the release process starts shortly after midnight UTC but it has to shuffle quite a lot of data around so it takes a bit).
