IntelliSense not working via remote connection

Open lijieamd opened this issue 1 year ago • 18 comments

Environment

I'm using SSH remote

  • OS and Version: Host: Windows 10 Enterprise 22H2 Guest: Ubuntu 22.04.3 LTS in VirtualBox 7.0.12
  • VS Code Version: Host: 1.86.0 Guest: 1.85.1
  • C/C++ Extension Version: Host: v1.18.5 (SSH side) Guest: v1.18.5

Bug Summary and Steps to Reproduce

Bug Summary: I'm developing via SSH remote connection, but IntelliSense doesn't seem to work on my host machine. I've also tried it directly on the guest machine, it's fine.

Steps to reproduce:

  1. Create my own C source file and working folder on the guest machine
  2. Connect to my guest machine using SSH on my host machine, open the working folder
  3. IntelliSense not working, lots of red squiggles displayed
  4. Install VScode (and C/C++ plugins) directly on the guest machine, open the same working folder
  5. IntelliSense worked well, no squiggles (hints appear on mouse hover; autocomplete works well)

Expected behavior: IntelliSense works on the host as well as local development on the guest.

Hi @lijieamd . Your C/C++ log output appears to start after the repro. Now that you've enabled debug logging, could you provide the log output from the start of a session in which the repro occurs

From your Log Diagnostics output, things appear to be getting configured correctly. Can you provide more information about your repro, and include the specific results you're seeing? Does this happen with a very simple example?

Colengms avatar Feb 07 '24 02:02 Colengms

Hi, @Colengms Yes, it is a very simple example (just one C source file) about socket network operation, I can't put screenshot or paste it here for some NDA reasons on my environment. (but it is really simple just including some socket(), bind(), write() things in main() )

I've reopen the working folder, here are the output ========================== C/C++: Log Diagnostics (host) ================================

Hi @lijieamd . Can you clarify what you're seeing, or expecting to see and not seeing? From your logs, it looks like things are working correctly. I see that IntelliSense appears to be configured properly for your file, and no issues are detected.

If the issue is that you're seeing 'squiggles', are you sure they're coming from the C/C++ Extension? Are there certain operations that are not working as you expect? We're not currently tracking any issue with basic functionality when using remotes (which would impact a large number of our users).

Colengms avatar Feb 07 '24 19:02 Colengms

Hi,@Colengms Here are the screenshots of the same working folder opened remotely(via ssh on host) and locally(on guest machine directly) respectively. IMG_20240208_093553_1

lijieamd avatar Feb 08 '24 01:02 lijieamd

You can see that IntelliSnese doesn't seem to work via remote SSH (hints can't appear on mouse hover; autocomplete doesn't work), but everything is fine when I use vscode directly on the guest machine.

lijieamd avatar Feb 08 '24 01:02 lijieamd

Hi @lijieamd . Sorry, I had interpreted your comments to indicate that your "guest" log, which displayed 0 squiggles, was the scenario you were reporting a problem with, not the "host" scenario. Thanks for clarifying.

Looking at a diff of your logs, it looks like exactly the same IntelliSense configuration is being used in both cases, yet only one is reporting errors.

What exactly at the errors that are reported? The first error might provide some clues.

Note that the extension does not do anything special for remoting. It runs on the 'remote' machine, presumably in exactly the same way that it runs when used directly on that machine without remoting. It's likely this is an issue with VS Code itself. Do you have any VS Code settings applied at a machine-scope that might be influencing behavior between these two scenarios?

Is it possible there is a permission issue preventing VS Code (and it's child processes) from accessing particular include paths while running via remoting?

Colengms avatar Feb 08 '24 03:02 Colengms

Hi @Colengms,

  • The reporting errors are just something like "identifier "XXXX" is undefined"
  • I didn't do much deep customisation of VS Code settings, just plugin installation. could you please guide me on how to check the settings that might cause this to happen?
  • I also thought about the permission issue, but I can open all the source code in working folder from my host machine via SSH including headers in search path.

lijieamd avatar Feb 08 '24 05:02 lijieamd

Hi @lijieamd .

Could you try setting, "C_Cpp.intelliSenseCacheSize": 0, and checking it the issue still repros? Setting that to 0 will also clear some temporary files. So, if that fixes it, you may be able to remove that setting afterwards to improve performance.

Colengms avatar Feb 08 '24 19:02 Colengms

Hi @Colengms, I've tried this setting "C_Cpp.intelliSenseCacheSize": 0, but it's still not working.

lijieamd avatar Feb 20 '24 01:02 lijieamd

I'm seeing the exact same behavior as @lijieamd although I'm using different compilers and oses.

I did some research and I found out that the C/C++ extension is working fine with v1.16.3 and starts to break with v1.17.2. So downgrading the remote extension to a version prior to 1.17.2 seems to fix the problem for me. Therefore I think that this is not a fundamental VSCode problem.

(local is where I'm running VSCode, remote is where the code is located and where I'm running the compiler)

  • OS and Version: local: macOS 14.3.1 remote: Fedora 39

  • VS Code Version: local: 1.87.0 remote: 1.87.0

  • C/C++ Extension Version: local: v1.19.6 remote: v1.19.6

Setting "C_Cpp.intelliSenseCacheSize": 0 does not work.

Example

#include <iostream>

int main()
{
   std::cout << "Hello, World!" << std::endl;
   return 0;
}

Hey @Colengms, this issue might need further attention.

@lijieamd, you can help us out by closing this issue if the problem no longer exists, or adding more information.

github-actions[bot] avatar Apr 07 '24 11:04 github-actions[bot]

@heikopanjas Thank you for your information ! I have downgraded the c++ extension to 1.16 but it doesn't solve my problem. I have no idea what has happened to my environment.

lijieamd avatar Apr 09 '24 01:04 lijieamd

This is the same as #11326. The problem also shows for remote WSL connections.

github-actions[bot] avatar Jun 06 '24 11:06 github-actions[bot]

Hi @lijieamd , @rubiot , @heikopanjas . I'm afraid we don't have enough information here to investigate. We're not able to repro a scenario in which simple functionality simply doesn't work in a remote session. If someone could provide the following full set of information from a repro, that would help a lot. I'd also recommend, if the issue is general or not well understood, creating a new issue instead of adding to an existing one, as most often it will not be the same root cause. If you are experiencing a problem with what appears to be a very simple scenario, that would seem to imply it's particularly likely that we will need very explicit details, as the issue would likely not exist if the majority of users encountered it.

We could use:

  • With the "C_Cpp.loggingLevel": "Debug" setting set, provide the output of the C/C++ Output pane, from launch up until the issue repros. This should give us a good record of what is going on in the extension up until that point.
  • With the file open that repro's the issue, run the C/C++: Log Diagnostics command, and provide that output that generates. This will give us the effective IntelliSense configuration actually used for that file.
  • The contents of your c_cpp_properties.json file (or any), and any C_Cpp related settings, or any other configuration information (such as compile_command.json command line, which configuration provider extension used, if any, etc.).
  • Clear repro steps. It's easy to omit things you don't think are important. But if the issue doesn't easily repro for us, there is likely some detail we will need to uncover in order to investigate further.
  • The list of error reported - most important the very first such unexpected error.
  • If possible, a self-contained repro in the form of a zip file or a github repo that we could easily install/extract to witness the issue. If this does not repro for us, that would tend to point to something on your system or in your local environment that would need to be understood to investigate the issue. Perhaps account permissions, missing packages, etc..

The reporting errors are just something like "identifier "XXXX" is undefined"

@lijieamd . I'd still like to understand exactly what the specific very first error is. What is undefined? Also, if the 'undefined' identifiers you are using are related to C++, be sure that, in addition to gcc, that the machine has both the g++ and build-essential packages installed. Those are necessary to get full C++ support on your system. However, I would also expect to see include statement with an error associated with it as well, which I can't discern whether or not exists from the information you provided.

@lijieamd What do you get when you do Go to Definition on cout? i.e. does it open /usr/include/c++/11/iostream?

sean-mcmanus avatar Jun 18 '24 19:06 sean-mcmanus

@sean-mcmanus Hi, I just can't go to definition on cout, it says "No definition found for cout"

Hey @Colengms, this issue might need further attention.

@lijieamd, you can help us out by closing this issue if the problem no longer exists, or adding more information.

This sounds like the same issue as https://github.com/microsoft/vscode-cpptools/issues/12455

This happens for all releases since v1.17.2 for all member of my team (some 5-10 guys). It happens for local Ubuntu users and WSL users. A comparison between v.1.16.3 and v.17.2 should be able point the culprit.

Hi @rubiot . Since this is not happening for most users, is there anything you can tell us about how your team is configuring VS Code and your Linux instances that might be unusual? Any more details you can give us about your repro environment may be helpful.

Could you try out prerelease builds between those versions (1.17.0, 1.17.1, also available via the marketplace, as prereleases)? That would help us narrow it down further.

@Colengms, we cross compile to a specific embedded system using gcc 12.2.0. But I don't think the cross-compiler is the problem, because the code should be valid for other configurations as well and I remember having Intellisense working right off the bat before a configure the right compiler.

I tried out the pre-release builds and the problem starts with v1.17.0.

Hi @rubiot . Another user (in a related issue) reported that the problem does not repro if using the target machine directly, not remoting into it. Can you confirm whether or not that is true for your repro as well?

Hi @rubiot . Another user (in a related issue) reported that the problem does not repro if using the target machine directly, not remoting into it. Can you confirm whether or not that is true for your repro as well?

Confirmed. Intellisense breaks even when using VSCode locally for our team. If I find any particular configuration of our project that could cause the breakage I'll let you know.

Intellisense breaks even when using VSCode locally for our team.

Hi @rubiot . You may be reproducing a different issue. This issue is tracking something that only happens via SSH and does not occur when not remoting.

From the original post:

I've also tried it directly on the guest machine, it's fine.

Could you open a new issue. Since your issue occurs locally and for everyone on your team, perhaps there is some specific code that the IntelliSense parser is failing to parse correctly.
