Rust-analyzer: Rust-Analyzer suddenly stopped working

[bdashore3]

Environment:

• WSL2 running Ubuntu 20.04
• Vscode 1.46.1
• RA 0.2.215

Hi there, I've been using rust-analyzer for a long time and it suddenly crashed on me after pressing update on vscode. The first thing I did was clean-reinstalling the extension which didn't work. Then, I clean installed vscode itself. Rust-analyzer still wouldn't activate.

After some searching, I found out how to enable logging in settings.json, and here's a picture on what the developer console showed me

I tried running /home/kingbri/.vscode-server/data/User/globalStorage/matklad.rust-analyzer/rust-analyzer-linux --version
in my terminal and this was the output: -bash: /home/kingbri/.vscode-server/data/User/globalStorage/matklad.rust-analyzer/rust-analyzer-linux: cannot execute binary file: Exec format error

What can I do to fix this issue? Thanks in advance for your help

[lnicola]

Can you try running file /home/kingbri/.vscode-server/data/User/globalStorage/matklad.rust-analyzer/rust-analyzer-linux?

[bdashore3]

@lnicola here's the output

/home/kingbri/.vscode-server/data/User/globalStorage/matklad.rust-analyzer/rust-analyzer-linux: data

[lnicola]

Sounds like it's corrupted. Can you remove that file and try again?

[bdashore3]

Vscode prompted me to download the binary again. Same error still pops up and same output from the file command

[lnicola]

Can you upload that file somewhere?

Here's the file

Same problem happen to me.
If I execute the command /home/kyasbal/.config/Code/User/globalStorage/matklad.rust-analyzer/rust-analyzer-linux --version directly, I could get an interesting log.

/home/kyasbal/.config/Code/User/globalStorage/matklad.rust-analyzer/rust-analyzer-linux: 1: Syntax error: ")" unexpected

I think this is just a --version for rust-analyzer, so I guess this command won't check syntax error of my code. I suspect this error happened inside of the command.

[lnicola]

@bdashore3 weird, you file is indeed not executable. Can you download it manually from here and put it in the same location? https://github.com/rust-analyzer/rust-analyzer/releases/tag/2020-06-22

It's also 27 949 394 instead of 27 966 344 bytes.

[bdashore3]

The vsix package or linux executable?

[Veetaha]

The linux exe

[lnicola]

@kyasbal-1994 can you run file and ls -l on /home/kyasbal/.config/Code/User/globalStorage/matklad.rust-analyzer/rust-analyzer-linux and possibly upload it somewhere if it doesn't show up as rust-analyzer-linux: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=df68b161b4040e76f637e26e634244c2e2b073d6, stripped?

@bdashore3 the Linux executable. Make sure to run chmod +x on it, though.

[bdashore3]

Will do, I'll show the results once I get them

[kyasbal-1994]

@lnicola Sure I will do that and report.

Anyway rust-analyzer works well if I downgraded to 0.2.207 which is the last version available on visual studio code extension menu. If there are someone just want to run rust-analyzer, you can use following link to downgrade the extension.

[Veetaha]

This might be related to #4963. I am not sure how tmp dir might affect the binary on WSL

[bdashore3]

@Inicola rust-analyzer --version works perfectly on the linux executable

[bdashore3]

@Veetaha Same issue happens on windows as well

[Veetaha]

Okay, thanks, I'll need to check this

[kyasbal-1994]

This is weird. I downgrade rust-analyzer to previous version and updated again. Then it works with the latest version and rust-analyzer-linux seems to be valid Linux ELF binary.

[lnicola]

@kyasbal-1994 should have tried that before :-).

[bdashore3]

It still errors out for me when downgrading/upgrading with the same error

[kyasbal-1994]

It still errors out for me when downgrading/upgrading with the same error

Did you download rust-analyzer server after downgrading extension?

[bdashore3]

Yes, I did. The downgrade works perfectly, it's only version 0.2.215 that errors out

[lnicola]

The file @bdashore3 uploaded is missing the first 16 950 bytes.

[frainho]

Downgrading worked for me as well.

I tried to remove rust-analyzer-mac but reinstalling the extension didn't trigger an installation of the binary.

[Veetaha]

I found the problem, we need a hotfix. We do skip the first chunks of the file....

[Veetaha]

This is very wierd beause on my machine (Ubuntu) it works even now, only in Windows Virtualbox this happens...

[jsj1027]

Running VSCode 1.46.1 on PopOs 20.04 which is based on Ubuntu 20.04.
Upgrading to 0.2.215 has basically disabled(?) rust-analyzer. No type hinting, no formatting. This is not only a windows problem.

Some specs here
OS: Pop!_OS 20.04 LTS x86_64
Kernel: 5.4.0-7634-generic
VSCode: 1.46.1
cd9ea6488829f560dc949a8b2fb789f3cdc05f5d
x64

Please let me know any other ways I can help or other info you need from my machine.

[bjorn3]

This has been fixed in #4989. The fix will be published next week.

[lnicola]

@jsj1027 this was just fixed. A new release will be available soon(ish) in the Marketplace.

[Veetaha]

This won't take a week, we will publish a patch today-or-tomorrow https://github.com/rust-analyzer/rust-analyzer/pull/4989#issuecomment-647668226
