Behaviour

Expected vs. Actual

Steps to reproduce:

  1. create interactive job with singularity compute
  2. open vscode link, the remote environment will be open, and debug python by attach running process id

Please contact @shantnu Suman, if you need to reproduce it

Diagnostic data

  • Python version (& distribution if applicable, e.g. Anaconda): 3.7.5
  • Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Global
  • Value of the python.languageServer setting: Default
Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

The attach to PID is taking longer than expected.
On Linux it's possible to customize the value of
`PYDEVD_GDB_SCAN_SHARED_LIBRARIES` so that fewer libraries.
are scanned when searching for the needed symbols.
i.e.: set in your environment variables (and restart your editor/client
so that it picks up the updated environment variable value):
PYDEVD_GDB_SCAN_SHARED_LIBRARIES=libdl, libltdl, libc, libfreebl3
-- the actual library may be different (the gdb output typically
-- writes the libraries that will be used, so, it should be possible
-- to test other libraries if the above doesn't work).

Sorry, but this isn't being investigated. Sounds like gdb can't attach to the process for some reason. You might try searching for similar errors for gdb.

Alternatively, if you have access to the source you're debugging, you can inject debugpy yourself. See the API docs:

I came across this comment #1196 (comment). And the problem went away when I did this:
sudo sysctl kernel.yama.ptrace_scope=0
