Description

@x1ntt
星途 (x1ntt)
opened on Nov 12, 2024

Environment

  • OS and Version: windows11 23H2
  • VS Code Version: 1.85.2
  • C/C++ Extension Version: 1.23.1
  • If using SSH remote, specify OS of remote machine: CentOS7.9

Bug Summary and Steps to Reproduce

Bug Summary:

I didn't find a pattern for its crashes. I only saw "IntelliSense process crashed handle_quick_info" in the output window, and obtained a large number of core files. It crashed very frequently, and each core was 200-300MB in size. I guess it should fill up my hard drive soon.
I need a way to stop this process from generating core files. For example, execute ulimit -c 0 only for this process

Expected behavior:
No Crash.

Configuration and Logs

Sorry, due to development environment limitations, I can't easily get the log file, but I can provide the stack trace

    In addition, I would like to ask by the way that there are multiple executable files in my project, so I wrote multiple configurations (such as game and cnet in the configuration file above), but when I edit the code files of the two modules, the configuration does not switch. Is there a way to switch automatically? Or how to configure auto-completion and reference search for multiple executable files in the project?

    星途 (@x1ntt) You can use a multi-root workspace, one workspace folder for each executable and each workspace folder can have a different configuration.

    星途 (@x1ntt) We're aware of that crash, although the additional crash data might help us. We were tracking it with #12666, but we believe there are multiple causes of the build_sections crash, so we can keep both issues open.

    星途 (@x1ntt) I'm not sure how you can configure your OS to stop logging crashes dumps. Our extension isn't creating though dmp files (although cpptools-srv is crashing). You can delete the dmp files.

    Are you able to find a sample repro code that repros the issue you can share with us?

    Setting the process to generate core is used to track bugs in our project. It is an accident to collect the core of cpptools-srv, but maybe it will be helpful? If there is any information that needs to be obtained from the core, I can provide help (such as specific stack, specific heap variables), can you give me a debug version of cpptools-srv with symbol information, or tell me how to build cpptools-srv (I hope this is cpp development), I can reproduce it 100% here (in fact, it has crashed dozens of times just a while ago, just clicking randomly or waiting for it to analyze the project), but I can't provide the core file (the project I maintain is not open source, nor does it belong to me, the core file may contain the project structure).

    For example, how is cpptools-srv started? I can execute ulimit -c 0 before its startup script or parent process starts to suppress the generation of core

    I will try to reproduce it using open source projects on my own personal computer, and pay attention to possible clues in existing projects. I will feedback here, or #12666 is also OK.

    I found a way to reproduce the crash 100% of the time
    Trigger by building https://github.com/yanwei1983/luatinkerE/tree/cxx20

    Here are the steps

    • clone code git clone git@github.com:yanwei1983/luatinkerE.git
    • Close vscode, reopen it, and open the project directory
    • Download version 5.3.4 from https://www.lua.org/ftp/, https://www.lua.org/ftp/lua-5.3.4.tar.gz
    • Unzip lua-5.3.4.tar.gz, unzip it to the luatinkerE/lua folder, and delete src/lua.c and src/luac.c
    • Modify CMakeLists.txt to the following content
    cmake_minimum_required(VERSION 3.8)
project(luatinkerE)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g ")

include(CheckCXXCompilerFlag)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++20")
#add_compile_options("-fno-limit-debug-info")

include_directories(lua/src luatinkere tests)

aux_source_directory(luatinkere cur_src)
aux_source_directory(tests cur_src)
aux_source_directory(lua/src cur_src)


link_directories(${CMAKE_CURRENT_SOURCE_DIR}/lua/src)

add_executable(test_runner ${cur_src})
target_link_libraries(test_runner dl)
#target_link_libraries(test_runner liblua.a dl)
    • mkdir build, cd build, cmake .., make -j90
    • Found code errors, fixed them, and recompiled
    • You can see cpp-tools crashing at this point
    • When clicking on a variable name in lua_tinker.h, IntelliSense process crash detected: handle_update_intellisense or handle_reference_highlight, handle_completion will appear

    I didn't know where the key steps were, so I recorded a video (there were a lot of invalid operations, I was a little nervous :(

    I saw your question(#12999 (comment)), and I changed the environment again to try to reproduce (wsl2 Ubuntu 22.04.4/gcc version 11.4.0/others are the same), and I still couldn't reproduce it.
    But I installed a clean Rockylinux9.5 (https://rockylinux.org/zh-CN/download) environment (gcc version 11.5.0 20240719) through the virtual machine, and reproduced it according to the following steps. Maybe it is easier to reproduce on rockylinux?

    1. The vscode on win11 remotely connects to the newly installed rockylinux9.5 in the virtual machine through remove-ssh
    2. In the vscode terminal, git clone https://github.com/yanwei1983/luatinkerE. And wget https://www.lua.org/ftp/lua-5.3.4.tar.gz, unzip it to luatinkerE/lua, and delete lua/src/lua.c and lua/src/luac.c
    3. Replace the content of luatinkerE/CMakeLists.txt with the following cmakelist.txt
    cmake_minimum_required(VERSION 3.8)
project(luatinkerE)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g ")

include(CheckCXXCompilerFlag)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++20")
#add_compile_options("-fno-limit-debug-info")

include_directories(lua/src luatinkere tests)

aux_source_directory(luatinkere cur_src)
aux_source_directory(tests cur_src)
aux_source_directory(lua/src cur_src)

link_directories(${CMAKE_CURRENT_SOURCE_DIR}/lua/src)

add_executable(test_runner ${cur_src})
target_link_libraries(test_runner dl)
#target_link_libraries(test_runner liblua.a dl)
    1. mkdir build; cmake ..; make -j8
    2. ** (Maybe this is the key point?) At this time, an error will appear. Hold down ctrl and click the corresponding error file path in the gcc error output to open the wrong header file in the editor and correct the error (indx->index)**
    3. Click on the variable definition nearby at random, and you should be able to observe the error at this time

    Similarly, a reproduction video is attached

    Encountered the same issue today, and downgrading to v1.21.6 seems to be a valid temporary bypass.

    I was able to reproduce and reduce the compare_expressions crash and opened a bug for our front-end compiler (EDG) to investigate. 2341984

    It is a result of this line (included from somewhere in <utility>): using make_integer_sequence = integer_sequence<_Tp, __integer_pack(_Tp(_Num))...>;

    on Ubuntu this line is: using make_integer_sequence = integer_sequence<_Tp, __integer_pack(_Num)...>;

    If you are able to reliably get a repro for the a_region_tracker::build_sections() we would still be interested in that.

    In addition to the stack information in the Output tab, is there any other information I can see? For example, logs?Or gdb debugger?
    What is a_region_tracker::build_sections() used for? How can I deliberately make it execute this function? My intranet project can easily trigger this problem in 1.23.1. I will try to build a project in the intranet to reproduce it.

    The region tracker's job is to keep track of edits in the file so that we can update IntelliSense incrementally instead of having to recompile the whole file for every edit. I think it makes it harder to reliably reproduce the problem because the order and location of the edits, the IntelliSense commands, and the contents of the file are all important.

    In your original post you show that a core dump was saved. Do you still have it and do you have a way to share it with us? But if there is proprietary code in your workspace, we cannot look at it because some of that information may be stored in the core dump.

    This is a closed source project, and the core contains code information, so I can't provide the core, sorry. I can easily trigger the build_sections error.
    Just wait for the scan to complete and click on the code to get ten cores immediately. Their contents are all as follows

    Although I can't provide the core file, I can debug it. If you can, you can tell me what variable information you need and what to focus on. I can leave my contact information so that I can tell you the results immediately (I am looking forward to the answer to this question and the fix of this problem. My discord username is x1nt, My time is GMT+8)

    In addition, other crashes were triggered during the reproduction process.

    I sent you a friend request on Discord. This is not code that my team is very familiar with, but we can try to gather some details to determine what the next steps are. I will take a look at the WSL dump.

    An instance of this was fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.24.0 . We're still looking into the root cause and other potentially cases.

    The uv_run crash or other cpptools-srv crashes that repro with C_Cpp.intelliSenseCacheSize not set to 0 is planned to be fixed in our next update (#12668).

    星途 (@x1ntt) We fixed the uv_run and build_sections crash with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.24.5, but not the compare_expressions or decl_specifiers crashes -- those 2 crashes are some of our highest remaining IntelliSense process crashes so any additional repro info you could provide would help...not sure if this issue should be closed or remain open to track those other crashes.
