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. +//---------------------------------------------------------------------- +class LocalDebugDelegate : public IDebugDelegate +{ + public: + explicit LocalDebugDelegate(lldb::ProcessWP process); + + void OnExitProcess(uint32_t exit_code) override; + void OnDebuggerConnected(lldb::addr_t image_base) override; + ExceptionResult OnDebugException(bool first_chance, const ExceptionRecord &record) override; + void OnCreateThread(const HostThread &thread) override; + void OnExitThread(lldb::tid_t thread_id, uint32_t exit_code) override; + void OnLoadDll(const lldb_private::ModuleSpec &module_spec, lldb::addr_t module_addr) override; + void OnUnloadDll(lldb::addr_t module_addr) override; + void OnDebugString(const std::string &message) override; + void OnDebuggerError(const Error &error, uint32_t type) override; + + private: + ProcessWindowsLiveSP + GetProcessPointer(); + + lldb::ProcessWP m_process; +}; +} + +#endif |
