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

error: internal compiler error: unexpected panic

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

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

    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.

    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).

    For Miri I already opened rust-lang/miri#947.

    @RalfJung the thing is currently all the tools and

    rust/src/tools/rustc-workspace-hack/Cargo.toml

    Line 69 in 74d5c70

    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 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

    will be released on 2019-09-17 00:00 UTC

    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).

    Compiled with:
    cargo build --all-features && cargo run --all-features
    and compile failed with several messages about ld not finding several items.

    Recompiled with:
    cargo build
    and finished successfully.
    Versions used:

    rustc 1.39.0-nightly (97e58c0d3 2019-09-20)
nushell 0.1.3

    Thanks to all for dealing with this ... cheers, drl

    Installed missing libraries, allowing build to complete, but with warnings. Assuming nu folks will deal with that. Thanks ... cheers, drl
