rustc could not initialize thread_rng (on pre-getrandom Linux kernel) #63848

lienke · 2019-08-24T13:26:37Z

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

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?

dhardy · 2019-08-24T20:40:57Z

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?

jonas-schievink · 2019-08-24T21:00:58Z

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

RalfJung · 2019-08-25T11:47:21Z

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?

RalfJung · 2019-08-25T11:56:32Z

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

error: aborting due to 34 previous errors

dhardy · 2019-08-25T16:46:28Z

@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.

mati865 · 2019-08-26T23:08:02Z

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.

nikomatsakis · 2019-08-29T13:54:39Z

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 · 2019-08-29T13:56:04Z

@rustbot assign @mati865

mati865 · 2019-09-11T07:07:46Z

@lienke #63806 was merged, could you check if latest nightly works for you?

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

lienke · 2019-09-11T15:08:46Z

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

$ ./rustup toolchain install nightly

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

RalfJung · 2019-09-11T15:18:07Z

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

lienke · 2019-09-11T15:22:11Z

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

mati865 · 2019-09-11T15:50:13Z

Thanks, it's valuable data.

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

lienke · 2019-09-11T15:55:06Z

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

newpavlov · 2019-09-11T15:55:59Z

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)

lienke · 2019-09-11T15:59:44Z

@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

mati865 · 2019-09-11T15:59:57Z

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.

mati865 · 2019-09-11T17:12:44Z

@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 · 2019-09-11T17:15:32Z

I'll see about the tools this or next week

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

mati865 · 2019-09-11T17:24:04Z

@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.

RalfJung · 2019-09-11T18:41:07Z

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.

Upgrade parking_lot and tempfile rustc dependencies This should be last piece to unbreak `rustc` in rust-lang#63848

Upgrade parking_lot and tempfile rustc dependencies This should be last piece to unbreak `rustc` in #63848

mati865 · 2019-09-16T17:32:22Z

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

RalfJung · 2019-09-16T17:51:13Z

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).

lienke · 2019-09-22T11:11:19Z

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

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