It tries to be as transparent as possible to let + * the guest (client) and host side do their protocol handling as desired. + * + * The following terms are used: + * - Host: A host process (e.g. VBoxManage or another tool utilizing the Main API) + * which wants to control something on the guest. + * - Client: A client (e.g. VBoxService) running inside the guest OS waiting for + * new host messages to perform. There can be multiple clients connected + * to this service. A client is represented by its unique HGCM client ID. + * - Context ID: An (almost) unique ID automatically generated on the host (Main API) + * to not only distinguish clients but individual requests. Because + * the host does not know anything about connected clients it needs + * an indicator which it can refer to later. This context ID gets + * internally bound by the service to a client which actually processes + * the message in order to have a relationship between client<->context ID(s). + * + * The host can trigger messages which get buffered by the service (with full HGCM + * parameter info). As soon as a client connects (or is ready to do some new work) + * it gets a buffered host message to process it. This message then will be immediately + * removed from the message list. If there are ready clients but no new messages to be + * processed, these clients will be set into a deferred state (that is being blocked + * to return until a new host message is available). + * + * If a client needs to inform the host that something happened, it can send a + * message to a low level HGCM callback registered in Main. This callback contains + * the actual data as well as the context ID to let the host do the next necessary + * steps for this context. This context ID makes it possible to wait for an event + * inside the host's Main API function (like starting a process on the guest and + * wait for getting its PID returned by the client) as well as cancelling blocking + * host calls in order the client terminated/crashed (HGCM detects disconnected + * clients and reports it to this service's callback). + * + * Starting at VBox 4.2 the context ID itself consists of a session ID, an object + * ID (for example a process or file ID) and a count. This is necessary to not break + * compatibility between older hosts and to manage guest session on the host. + */ + + +/********************************************************************************************************************************* +* Header Files * +*********************************************************************************************************************************/ +#define LOG_GROUP LOG_GROUP_GUEST_CONTROL +#include <VBox/HostServices/GuestControlSvc.h> +#include <VBox/GuestHost/GuestControl.h> /** @todo r=bird: Why two headers??? */ + +#include <VBox/err.h> +#include <VBox/log.h> +#include <VBox/AssertGuest.h> +#include <VBox/VMMDev.h> +#include <VBox/vmm/ssm.h> +#include <iprt/assert.h> +#include <iprt/cpp/autores.h> +#include <iprt/cpp/utils.h> +#include <iprt/mem.h> +#include <iprt/list.h> +#include <iprt/req.h> +#include <iprt/string.h> +#include <iprt/thread.h> +#include <iprt/time.h> + +#include <map> +#include <new> /* for std::nothrow*/ + + +using namespace guestControl;

The service is split + * into a platform-independent core and platform-specific backends. The + * service defines two communication protocols - one to communicate with the + * clipboard service running on the guest, and one to communicate with the + * backend. These will be described in a very skeletal fashion here. + * + * @section sec_hostclip_guest_proto The guest communication protocol + * + * The guest clipboard service communicates with the host service via HGCM + * (the host service runs as an HGCM service). The guest clipboard must + * connect to the host service before all else (Windows hosts currently only + * support one simultaneous connection). Once it has connected, it can send + * HGCM messages to the host services, some of which will receive replies from + * the host. The host can only reply to a guest message, it cannot initiate + * any communication. The guest can in theory send any number of messages in + * parallel (see the descriptions of the messages for the practice), and the + * host will receive these in sequence, and may reply to them at once + * (releasing the caller in the guest) or defer the reply until later. + * + * There are currently four messages defined. The first is + * VBOX_SHARED_CLIPBOARD_FN_GET_HOST_MSG, which waits for a message from the + * host. Host messages currently defined are + * VBOX_SHARED_CLIPBOARD_HOST_MSG_QUIT (unused), + * VBOX_SHARED_CLIPBOARD_HOST_MSG_READ_DATA (request that the guest send the + * contents of its clipboard to the host) and + * VBOX_SHARED_CLIPBOARD_HOST_MSG_FORMATS (to notify the guest that new + * clipboard data is available). If a host message is sent while the guest is + * not waiting, it will be queued until the guest requests it. At most one + * host message of each type will be kept in the queue. The host code only + * supports a single simultaneous VBOX_SHARED_CLIPBOARD_FN_GET_HOST_MSG call + * from the guest. + * + * The second guest message is VBOX_SHARED_CLIPBOARD_FN_FORMATS, which tells + * the host that the guest has new clipboard data available. The third is + * VBOX_SHARED_CLIPBOARD_FN_READ_DATA, which asks the host to send its + * clipboard data and waits until it arrives. The host supports at most one + * simultaneous VBOX_SHARED_CLIPBOARD_FN_READ_DATA call from the guest - if a + * second call is made before the first has returned, the first will be + * aborted. + * + * The last guest message is VBOX_SHARED_CLIPBOARD_FN_WRITE_DATA, which is + * used to send the contents of the guest clipboard to the host. This call + * should be used after the host has requested data from the guest. + * + * @section sec_hostclip_backend_proto The communication protocol with the + * platform-specific backend + * + * This section may be written in the future :) + */ + + +/********************************************************************************************************************************* +* Header Files * +*********************************************************************************************************************************/ +#define LOG_GROUP LOG_GROUP_SHARED_CLIPBOARD +#include <VBox/HostServices/VBoxClipboardSvc.h> +#include <VBox/HostServices/VBoxClipboardExt.h> + +#include <iprt/alloc.h> +#include <iprt/string.h> +#include <iprt/assert.h> +#include <iprt/critsect.h> +#include <VBox/err.h> +#include <VBox/vmm/ssm.h> + +#include "VBoxClipboard.h" + + +/********************************************************************************************************************************* +* Global Variables * +*********************************************************************************************************************************/ +static PVBOXHGCMSVCHELPERS g_pHelpers;

In Mac OS X there is + * the concept of translucent canvas's e.g. windows and there it is just + * painted what should be visible to the user. Unfortunately this isn't the + * concept of chromium. Therefor I reroute all OpenGL operation from the guest + * to a frame buffer object (FBO). This is a OpenGL extension, which is + * supported by all OS X versions we support (AFAIC tell). Of course the guest + * doesn't know that and we have to make sure that the OpenGL state always is + * in the right state to paint into the FBO and not to the front/back buffer. + * Several functions below (like cocoaBindFramebufferEXT, cocoaGetIntegerv, + * ...) doing this. When a swap or finish is triggered by the guest, the + * content (which is already bound to an texture) is painted on the screen + * within a separate OpenGL context. This allows the usage of the same + * resources (texture ids, buffers ...) but at the same time having an + * different internal OpenGL state. Another advantage is that we can paint a + * thumbnail of the current output in a much more smaller (GPU accelerated + * scale) version on a third context and use glReadPixels to get the actual + * data. glReadPixels is a very slow operation, but as we just use a much more + * smaller image, we can handle it (anyway this is only done 5 times per + * second). + * + * Other things to know: + * - If the guest request double buffering, we have to make sure there are two + * buffers. We use the same FBO with 2 color attachments. Also glDrawBuffer + * and glReadBuffer is intercepted to make sure it is painted/read to/from + * the correct buffers. On swap our buffers are swapped and not the + * front/back buffer. + * - If the guest request a depth/stencil buffer, a combined render buffer for + * this is created. + * - If the size of the guest OpenGL window changes, all FBO's, textures, ... + * need to be recreated. + * - We need to track any changes to the parent window + * (create/destroy/move/resize). The various classes like OverlayHelperView, + * OverlayWindow, ... are there for. + * - The HGCM service runs on a other thread than the Main GUI.
