| // LocalDebugDelegate |
| // |
| // LocalDebugDelegate creates a connection between a ProcessWindows and the |
| // debug driver. This serves to decouple ProcessWindows from the debug |
| // driver. It would be possible to get a similar decoupling by just having |
| // ProcessWindows implement this interface directly. There are two reasons |
| // why we don't do this: |
| // |
| // 1) In the future when we add support for local debugging through LLGS, and we |
| // go through the Native*Protocol interface, it is likely we will need the |
| // additional flexibility provided by this sort of adapter pattern. |
| // 2) LLDB holds a shared_ptr to the ProcessWindows, and our driver thread |
| // needs access to it as well. To avoid a race condition, we want to make |
| // sure that we're also holding onto a shared_ptr. |
| // lldb_private::Process supports enable_shared_from_this, but that gives us |
| // a ProcessSP (which is exactly what we are trying to decouple from the |
| // driver), so this adapter serves as a way to transparently hold the |
| // ProcessSP while still keeping it decoupled from the driver. |
