VM Crash when deleting a folder that is an analysis root

Open DanTup opened this issue 6 months ago • 1 comments

While trying to repro https://github.com/dart-lang/sdk/issues/60863 I was running the Dart analysis server from source and deleted a folder that was being watched as an analysis root. The process terminated with the crash below.

@DanTup can you provide some reproduction instructions, I would like to see if it reproduces on Linux.

Sorry, I should've included more info. I can still repro today, but it requires checking out a slightly older SDK (the one I was testing with above) and a bit of fiddling:

  • git checkout ca9523058e67ab197b2ae0453ad2db49707c11cc
  • gclient sync -D
  • ./tools/build.py --mode release --arch x64 create_sdk
  • Clone https://github.com/DanTup/dart-repro-60866
  • Open dart_application_1_2_3.code-workspace in a text editor and update:
    • dart.sdkPath to point at your built SDK
    • dart.analyzerPath to point at the analysis server entry point (since we're running from source)
  • Now open VS Code and use File -> Open Workspace to open dart_application_1_2_3.code-workspace as a workspace (it will open a workspace with the three sub folders as "workspace folders")
  • Outside of VS Code, delete the dart_application_2 folder (note: for me, it seems like this might only occur if I shift+delete to skip the recycle bin, but not certain!)
  • This causes the analysis server to crash (open the logs/analyzer.txt file for the stderr output)

I was also able to reproduce by using a recent bleeding-edge build of the SDK too (which avoids building the SDK), but still running the analysis server from source using the commit above (some analysis server code has changed since that commit which presumably is avoiding the crash).

If you can't repro and there's anything I can do to get more info that will help, please let me know!

An updated stack using the SDK built from that commit (which may differ from the above, which was potentially running a different bleeding-edge build):
