cpptools hardcodes "set debuginfod enabled on" AFTER processing user setupCommands and gdbinit files

[jvillemure]

Type: Bug

GDB hangs during debug launch because debuginfod.ubuntu.com is down (LP#2153433) since yesterday. GDB tries to download debuginfo for every shared library, timing out after ~90s each.

It would be easy to get around this issue by calling the gdb command "set debuginfod enabled off" from a gdbinit file or in "setupCommands", but cpptools doesn't honor those and always end up forcing back "set debuginfod enabled on".

I can't start vscode-server with a modified DEBUGINFOD_URLS="" environment variable; devcontainer add the flag --force-disable-user-env.

The last alternatives are, unsatisfactory, unpleasant workarounds that require either writing system settings file(s) /etc/debuginfod/elfutils.urls (requires admin user) or rebuilding the devcontainer with "remoteEnv": {"DEBUGINFOD_URLS": ""}. These workaround would only be good if they fixed a permanent problem, which is not the case here: as soon as the host "debuginfod.ubuntu.com" is back online the workaround needs to be easily undone.

Expected Behavior: The cppdbg debug adapter should not undo what the developer specifies in gdbinit files or in "setupCommands". In particular, if I "set debuginfod enabled off", then I really mean that my machine or the remote host are not capable of communicating.
