error[E0277]: `syntax_pos::symbol::LocalInternedString` cannot be sent between threads safely

EDIT: tl;dr: this error(and the 3 others inside Details below) happens because I've compiled rustc with non-default config.toml setting: experimental-parallel-queries = true

In trying to compile rust-clippy's latest commit 85ba5f0 I get the following error:

$ cargo clippy -V

clippy 0.0.212 (39bd844 2018-12-30)

(that must be rustup's clippy)

I realized that the fail is also seen here: https://rust-lang-nursery.github.io/rust-toolstate/ and points to these rust changes https://github.com/rust-lang/rust/commits/cae164753f557f668cb75610abda4f790981e5e6

[flip1995]

I can't reproduce this with the current rust-lang/rust master branch.
Running

rustup-toolchain-install-master -f -n master
cargo +master build

works for me.

https://rust-lang-nursery.github.io/rust-toolstate/ is test-pass again.

Am I missing something?

I'm not sure(I haven't tried it that way), but that link now shows:

Tool | Linux | Windows | In this state since…
clippy-driver | test fail | test fail | a36b960df on 2019-01-02 14:37:47
...
rls | build fail | build fail | cae164753 on 2019-01-01 18:04:04

Maybe rls has nothing to do with clippy? but that's what I was referring to in OP when I said "I realized that the fail is also seen here"

[mati865]

In this state since…
a36b960 on 2019-01-02 14:37:47

It means clippy broke few hours ago but #3609 should fix it.

oh my bad, it then fails(like in OP) only for me... probably my fault - I'll try to figure out something

[flip1995]

The only difference I see between your setup and mine is the cargo commit:

cargo 1.33.0-nightly (0d1f1bbea 2018-12-19)
release: 1.33.0
commit-hash: 0d1f1bbeabd5b43a7f3ecfa16540af8e76d5efb4
commit-date: 2018-12-19

This is the current cargo commit on the rust-lang/rust master branch

uuu, that is good information @flip1995 ! (meanwhile github decided to crash with unicorns hence why this info is delayed by a few minutes)
I can confirm that rust-clippy compiles successfully using that cargo AND a different rustc:

EDIT: Oh I just noticed that I also fell back to the rustup rustc also! hmm...
I now recompiled and ensured that I'm was using the OP rustc, but with rustup's cargo and the OP error is back!

Ok, I can confirm that it works when I use rustup's cargo AND rustc (as per my previous comment), but it fails when I use rustup's(or even master) cargo AND my locally compiled rustc:

Therefore the issue must be in something(that I changed?) in my local rustc compilation. Or, a certain cargo+rustc combination is required?

@flip1995 can you please tell me your rustc -Vv for your working rust-clippy compilation?

Edit: I'm recompiling rustc, at the very least I didn't do this git submodule update --init --recursive --progress (I only did git pull) so this might be it...

this is what I've had before:

Hmm, so no change then... except that I didn't have anything checkout for: src/llvm-emscripten src/tools/clang src/tools/lld src/tools/lldb, ie. those dirs were empty (except for the .git file(not dir) itself)

[mati865]

@xftroxgpx you should update submodules by running ./x.py. It should sync them and checkout the correct version.

When key tools like clippy or rls are broken (just like at the moment) you have to fix them by yourself.
Clippy has fix commited already so if you are using the latest rust HEAD you can checkout latest clippy HEAD and it should work.
Rls has no fix yet so you'd have to fix it yourself.

Easier alternative would be to exclude broken tools or checkout rust commit where they do work.

Thanks! That explains why the submodules were already updated because I was using ./x.py.

Then maybe these rustc build instructions are outdated:

3. Build and install:

$ git submodule update --init --recursive --progress
$ ./x.py build && sudo ./x.py install

I'm not even sure that git submodule command is ever needed, presumably due to ./x.py doing it. By doing it manually I gained about 3 more Gigabytes in the rust checkout dir because that git submodule command checked out some extras like src/llvm-emscripten, src/tools/clang, src/tools/lld, src/tools/lldb that were empty dirs (except for the .git file) before, presumably because ./x.py knew they weren't needed!

[mati865]

./x.py doesn't initialize submodules so you still have to run git submodule update --init --recursive --progress when new submodule is added.
git submodule update --init just doesn't do anything to the already initialized submodules.

[flip1995]

@xftroxgpx I tested it with your rustc commit from the OP, the latest master commit and the rustup nightly toolchain. I used the cargo I posted above (resp. the one from rustup nightly).

It's probably something you changed and/or a certain cargo+rustc combination. But as long as Clippy compiles with the current master branch of rust-lang/rust (which is tested in the CI), we can't do much here for you. :(
