From 036bc3e2cfc5a11c3f7ace41088c8936dae2e946 Mon Sep 17 00:00:00 2001 From: Igor Murashkin Date: Mon, 8 Oct 2012 15:09:46 -0700 Subject: Camera2: Always disconnect in the client destructor If Camera2Client failed to initialize, it would skip disconnect step, and thus the camera would be forever marked as busy. By always calling disconnect it will always call free. It also adds a new guarantee that Client::disconnect is idempotent Bug: 7298182 Change-Id: Ic9876f1665b7d9b3c0da692880f63f165e3f4fa5 --- services/camera/libcameraservice/CameraService.cpp | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'services/camera/libcameraservice/CameraService.cpp') diff --git a/services/camera/libcameraservice/CameraService.cpp b/services/camera/libcameraservice/CameraService.cpp index 6fbd6ed..124d24d 100644 --- a/services/camera/libcameraservice/CameraService.cpp +++ b/services/camera/libcameraservice/CameraService.cpp @@ -409,6 +409,9 @@ CameraService::Client::Client(const sp& cameraService, // tear down the client CameraService::Client::~Client() { mCameraService->releaseSound(); + + // unconditionally disconnect. function is idempotent + Client::disconnect(); } // ---------------------------------------------------------------------------- @@ -433,6 +436,7 @@ CameraService::Client* CameraService::Client::getClientFromCookie(void* user) { return client; } +// NOTE: function is idempotent void CameraService::Client::disconnect() { mCameraService->removeClient(mCameraClient); mCameraService->setCameraFree(mCameraId); -- cgit v1.1
