I was wondering how this worked in the regular SBAPI that we use for all the "normal" python-based LLDB tests. The implementation of SBProcess::Continue() for example calls Process::Resume() or Process::ResumeSynchronous() depending on whether synchronous mode is set or not. It's not immediately obvious to me whether -exec-run should wait until the process stopped before returning or whether -exec-step should wait until the process stopped before executing.
Based on a cursory reading of the sources it seems like SBTarget::Launch should block until the process stopped when it is in synchronous mode. Can you confirm this? If that is the case, can you figure out why -exec-run does not inherit this behavior? -- adrian > On Aug 10, 2018, at 4:27 PM, Александр Поляков <polyakov....@gmail.com> wrote: > > AFAIK, there is no mechanism in lldb-mi to distinguish a command that expects > a frame, so we need to modify each command manually.
