RLS crashes in VSCode #312

rnleach · 2017-05-11T04:47:50Z

It just crashes on any project in Ubuntu 16.04. Chatted about it in #rust-tools with @jonathandturner and it seems it has something to do with latest rustup release.

sophiajt · 2017-05-11T08:54:47Z

rust-lang/rust#41900 just landed. With luck, this should roll out soon.

sophiajt · 2017-05-12T00:28:07Z

No luck... still seeing the crash even with the updated nightly

FaultyRAM · 2017-05-12T06:53:00Z

I'm also getting crashes with VSCode, but on Windows 10 Pro x64 1703.

Enet4 · 2017-05-12T18:27:39Z

I'm replicating some information from editor-rs/vscode-rust#229, because I've looked into the matter and it might not be more an issue with the Rust extension than I had initially thought.

The RLS type definition ClientCapabilties was recently changed from a generic JSON value to a JSON object with the fields "workspace", "textDocument" and "experimental", in accordance to the language server protocol. Although we could just make sure that the extension always provides the three fields, the specification on initializing requests explicitly states that "a missing property should be interpreted as an absence of the capability", and not as a problem with the client. Would it be sufficient if we gave these fields default values when deserializing? :)

Edit: There's an issue over at gluon-lang/lsp-types#14 already.

Marwes · 2017-05-12T19:18:16Z

0.9.0 (with the required fixed) of languageserver-types is now published

- update "languageserver-types" to 0.9.0 - modify initialization params to use `None` in experimental field of ClientCapabilities - change tests to consider an empty object in client capabilities

kmod-midori · 2017-05-13T00:10:01Z

When will the fix be available in rustup?

Enet4 · 2017-05-13T00:18:29Z

Since nightly builds are updated nearly daily (upon new passing changes in the master branch) , it should become available tomorrow. Meanwhile, you can build RLS from source yourself.

kmod-midori · 2017-05-13T01:13:30Z

It crashes...

rnleach · 2017-05-13T02:11:45Z

I just ran rustup, my nightly is now at 2017-05-12 and it still crashes.

@nrc - did you update the submodule in rustc when you closed this? To be on the safe side, reopening this until we can confirm the fix works via rustup, since that's how most people will get it.

kmod-midori · 2017-05-13T05:24:30Z

@jonathandturner He didn't update it..

The error "missing field experimental" should no longer happen with the fix in #313. It might be that it simply hasn't landed in Nightly yet. How can we verify this?

kmod-midori · 2017-05-13T11:10:24Z

I think we need a pull request..... I am not seeing any RLS-related commits, only rust-lang/rust@1ffa6b731e which happened few days ago...

Enet4 · 2017-05-13T11:46:14Z

Ah, so we need to update the rls submodule in the Rust repository? Allow me to propose another RLS update then.

kmod-midori · 2017-05-13T12:01:03Z

Yeah, we need a pull request.

@martinschleiss I'm afraid I cannot reproduce that in my system. It's also definitely not the same issue as those observed before. What language server consumer have you used?

ghost · 2017-05-13T12:14:44Z

I'm using jonathan's vscode extension

kmod-midori · 2017-05-13T12:18:09Z

It shouldn't happen according to the code...

Enet4 · 2017-05-13T12:25:10Z

The "rootUri" field is clearly optional. I would advise you to make sure that you have built from the latest position in the master branch.

Hi, I'm new to Rust, is there anykind of respin in nightly to push critical fixes quicker?

light4 · 2017-05-14T10:35:27Z

@Geobert You can add date to nightly, just like this:

rustup override set nightly-2017-05-10
rustup component add rls --toolchain nightly-2017-05-10
rustup component add rust-analysis --toolchain nightly-2017-05-10
rustup component add rust-src --toolchain nightly-2017-05-10

sophiajt · 2017-05-14T21:03:09Z

@Geobert - To my knowledge, the current infrastructure only lets us spin at night.

rnleach · 2017-05-14T23:18:34Z

@jonathandturner at night in what country/timezone? ;)

sophiajt · 2017-05-14T23:23:18Z

@Enet4 \o/ Have you tested that the RLS now runs without crashes?

Enet4 · 2017-05-15T00:42:16Z

@nrc I tested it on my machine and it all worked well. Still, it wouldn't hurt to have a few more people try it out before we close.

Awesome, thanks @Enet4 !

josephlr · 2017-06-28T05:29:35Z

RLS is still crashing for me on any project (although it takes longer than before), see rust-lang/vscode-rust#67. I'm on rustc 1.20.0-nightly (f590a44 2017-06-27) (nightly-x86_64-apple-darwin).

zmanian · 2017-06-28T05:35:05Z

rls --version will give you commit hash and date for the rls version. You'll see it is currently from 6/20. I think the fix for this was merged on 6/24. @nrc mentioned deploying > 6/20 to rustup in the next couple days.

josephlr · 2017-06-28T06:55:50Z

Thanks @zmanian, I had gotten rustc 2017-06-27 and rls 2017-06-20 switched. Everything's great after rebuilding from source!
