Summary: The IDE has no packets that are sent to lldb-vscode that say which thread and frame are selected. The only way we know is we get a request for variables for a stack frame via a "scopes" request. When we receive this packet we make that thread and frame the selected thread and frame in lldb. This way when people execute lldb commands in the debug console by prefixing the expression with the backtick character, we will have the right thread and frame selected. Previously this was not updated as new stack frames were selected.

Tests that the "scopes" request causes the currently selected
|
|
thread and frame to be updated. There are no DAP packets that tell
|
|
lldb-vscode which thread and frame are selected other than the
|
|
"scopes" request. lldb-vscode will now select the thread and frame
|
|
for the latest "scopes" request that it receives.
|
|
|
|
The LLDB command interpreter needs to have the right thread and
|
|
frame selected so that commands executed in the debug console act
|
|
on the right scope. This applies both to the expressions that are
|
|
evaluated and the lldb commands that start with the backtick
|
|
character.
