Rls: Compiler panic while running `rls --cli`

[norru]

Crash doesn't happen on normal "cargo build", only when running rls --cli on the same crate.

UPDATE: Still open with rustc 1.32.0-nightly (15d770400 2018-11-06) running on x86_64-unknown-linux-gnu

RLS basically unusable.

{"jsonrpc":"2.0","method":"window/progress","params":{"id":"progress_1","message":"gdk","title":"Building"}}
thread 'main' panicked at 'No span found for use glob', libcore/option.rs:1008:5
note: Run with `RUST_BACKTRACE=1` for a backtrace.

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

note: rustc 1.31.0-nightly (96064eb61 2018-10-28) running on x86_64-unknown-linux-gnu

note: compiler flags: -C debuginfo=2 --crate-type lib

note: some of the compiler flags provided by cargo are hidden

Works fine for me, which crate do you want to compile?

[norru]

Unfortunately I cannot disclose the crate's code. It might be failing to build the dependent palette crate but I haven't tracked that down exactly.

This happens 100% on my specific crate but other crates are unaffected.

[norru]

Besides, FYI, this happened while I was trying to narrow https://github.com/rust-lang-nursery/rls/issues/1106 down

Also, downgrading to nightly 2018-09-20 stops the crash from happening. Also fixes #1106. Trying more recent nightly now.

[norru]

nightly-2018-10-20 also unaffected by the crash, but has #1106

[norru]

nightly-2018-10-17 unaffected by the crash, unaffected by #1106

[norru]

Will stick to nightly-2018-10-17 for the time being.

[lweberk]

Took the liberty to create a small project that breaks with this message... https://github.com/lweberk/bug-rls-1107.

Its basically a bare bone rocket project with only rocket and rocket_codegen as immediate dependencies.

Environment prep and execution to achieve the error:

• rustup override set nightly
• RUST_BACKTRACE=1 rls --cli

Edit: maybe worth adding:

• rustup run nightly rls --version => rls-preview 0.130.5 (1c755ef 2018-10-20)

[lweberk]

Can confirm the earliest nightly version failing in the case of https://github.com/lweberk/bug-rls-1107 is 2018-10-27. Narrowed down to 2018-10-26 being the last working one.

[norru]

Still open as for 2018-11-06

[norru]

Still open with rustc 1.32.0-nightly (15d770400 2018-11-06) running on x86_64-unknown-linux-gnu

[jnicholls]

I suppose, then, that this is a 1.32 + rls issue, since it was when we moved into the 1.32 series that the issue crept up.

[norru]

@jnicholls It was there in rustc 1.31.0-nightly (96064eb 2018-10-28) when I initially reported it.

[Xanewok]

After some investigating it turns out #1117 boils down to the same problem and since I left some more context and it's already labeled there, I'll close this as dup and track the underlying bug there. Thanks for the report, I'm looking into this!

[norru]

@Xanewok sounds like a plan, cheers! :)
