There is a 15 // DevToolsManager living in the browser process that is responsible for 16 // routing logistics. It is also capable of sending direct messages to the 17 // agent rather than forwarding messages between agents and clients only. 18 // 19 // Chain of communication between the components may be described by the 20 // following diagram: 21 // ---------------------------- 22 // | (tools frontend | 23 // | renderer process) | 24 // | | -------------------- 25 // |tools <--> DevToolsClient+<-- IPC -->+ (browser process) | 26 // |frontend | | | 27 // ---------------------------- ---------+---------- 28 // ^ 29 // | 30 // IPC 31 // | 32 // v 33 // --------------------------+-------- 34 // | inspected page <--> DevToolsAgent | 35 // | | 36 // | (inspected page renderer process) | 37 // ----------------------------------- 38 // 39 // This file describes developer tools message types. 40 41 // Multiply-included message file, no standard include guard. 42 #include <map> 43 #include <string> 44 45 #include "content/common/content_export.h" 46 #include "content/public/common/common_param_traits.h" 47 #include "content/public/common/console_message_level.h" 48 #include "ipc/ipc_message_macros.h" 49 50 #undef IPC_MESSAGE_EXPORT 51 #define IPC_MESSAGE_EXPORT CONTENT_EXPORT 52 53 #define IPC_MESSAGE_START DevToolsMsgStart 54 55 // These are messages sent from DevToolsAgent to DevToolsClient through the 56 // browser. 57 // WebKit-level transport. 58 IPC_MESSAGE_ROUTED1(DevToolsClientMsg_DispatchOnInspectorFrontend, 59 std::string /* message */) 60 61 //----------------------------------------------------------------------------- 62 // These are messages sent from DevToolsClient to DevToolsAgent through the 63 // browser. 64 // Tells agent that there is a client host connected to it. 65 IPC_MESSAGE_ROUTED0(DevToolsAgentMsg_Attach) 66 67 // Tells agent that a client host was disconnected from another agent and 68 // connected to this one. 69 IPC_MESSAGE_ROUTED1(DevToolsAgentMsg_Reattach, 70 std::string /* agent_state */) 71 72 // Tells agent that there is no longer a client host connected to it. 73 IPC_MESSAGE_ROUTED0(DevToolsAgentMsg_Detach) 74 75 // WebKit-level transport. 76 IPC_MESSAGE_ROUTED1(DevToolsAgentMsg_DispatchOnInspectorBackend, 77 std::string /* message */) 78 79 // Inspect element with the given coordinates. 80 IPC_MESSAGE_ROUTED2(DevToolsAgentMsg_InspectElement, 81 int /* x */, 82 int /* y */) 83 84 // Add message to the devtools console. 85 IPC_MESSAGE_ROUTED2(DevToolsAgentMsg_AddMessageToConsole, 86 content::ConsoleMessageLevel /* level */, 87 std::string /* message */) 88 89 // Notifies worker devtools agent that it should pause worker context 90 // when it starts and wait until either DevTools client is attached or 91 // explicit resume notification is received. 92 IPC_MESSAGE_ROUTED0(DevToolsAgentMsg_PauseWorkerContextOnStart) 93 94 // Worker DevTools agent should resume worker execution. 95 IPC_MESSAGE_ROUTED0(DevToolsAgentMsg_ResumeWorkerContext) 96 97 //----------------------------------------------------------------------------- 98 // These are messages sent from the browser to the renderer. 99 100 // RenderViewHostDelegate::RenderViewCreated method sends this message to a 101 // new renderer to notify it that it will host developer tools UI and should 102 // set up all neccessary bindings and create DevToolsClient instance that 103 // will handle communication with inspected page DevToolsAgent. 104 IPC_MESSAGE_ROUTED0(DevToolsMsg_SetupDevToolsClient) 105 106 107 //----------------------------------------------------------------------------- 108 // These are messages sent from the renderer to the browser. 109 110 // Transport from Inspector frontend to frontend host. 111 IPC_MESSAGE_ROUTED1(DevToolsHostMsg_DispatchOnEmbedder, 112 std::string /* message */) 113 114 // Updates agent runtime state stored in devtools manager in order to support 115 // cross-navigation instrumentation. 116 IPC_MESSAGE_ROUTED1(DevToolsHostMsg_SaveAgentRuntimeState, 117 std::string /* state */) 118 119 // Clears browser cache. 120 IPC_MESSAGE_ROUTED0(DevToolsHostMsg_ClearBrowserCache) 121 122 // Clears browser cookies. 123 IPC_MESSAGE_ROUTED0(DevToolsHostMsg_ClearBrowserCookies) 124 125 //----------------------------------------------------------------------------- 126 // These are messages sent from the GPU process to the inspected renderer. 127 128 IPC_STRUCT_BEGIN(GpuTaskInfo) 129 IPC_STRUCT_MEMBER(double, timestamp) 130 IPC_STRUCT_MEMBER(int, phase) 131 IPC_STRUCT_MEMBER(bool, foreign) 132 IPC_STRUCT_MEMBER(uint64, used_gpu_memory_bytes) 133 IPC_STRUCT_END() 134 135 // Recorded events are passed in chunks to the renderer process. 136 IPC_MESSAGE_ROUTED1(DevToolsAgentMsg_GpuTasksChunk, 137 std::vector<GpuTaskInfo> /* gpu_tasks */) 138 139 //----------------------------------------------------------------------------- 140 // These are messages sent from the inspected page renderer to the worker 141 // renderer. 142
