2021-10-12android: camera_device: Fix crash in calling CameraDevice::close()Hirokazu Honda
The problem is happening because we seem to add a CameraStream associated buffer (depending on the CameraStream::Type) to the Request, in CameraDevice::processCaptureRequest(). However, when the camera stops, all the current buffers are marked with FrameMetadata::FrameCancelled and proceed to completion. But the buffer associated with the CameraStream (that was previously added to the request) has now been cleared out with a part of streams_.clear(), even before the camera stop() has been invoked. Any access to those request buffers after they have been cleared, will result in a crash.

2021-09-30android: camera_device: Send capture results by inspecting the queueUmang Jain
There is a possibility that an out-of-order completion of capture request happens by calling process_capture_result() directly on error paths. The framework expects that errors should be notified as soon as possible, but the request completion order should remain intact. An existing instance of this is abortRequest(), which sends the capture results on flushing state, without considering order-of-completion. Since we have a queue of Camera3RequestDescriptor tracking each capture request placed by framework to libcamera HAL, we should be only sending back capture results from a single location, by inspecting the queue. As per the patch, this now happens in CameraDevice::sendCaptureResults(). Each descriptor is now equipped with its own status to denote whether the capture request is complete and ready to be send back to the framework or needs to be waited upon. This ensures that the order of completion is respected for the requests. Since we are fixing out-of-order request completion in abortRequest(), change the function to read from the Camera3RequestDescriptor directly, instead of camera3_capture_request_t. The descriptor should have all the information necessary to set the request buffers' state to error.

2021-09-30android: camera_device: Transform descriptors_ map to queueUmang Jain
The descriptors_ map holds Camera3RequestDescriptor(s) which are per-capture requests placed by the framework to libcamera HAL. CameraDevice::requestComplete() looks for the descriptor for which the camera request has been completed and removes it from the map. Since the requests are placed in form of FIFO and the framework expects the order of completion to be FIFO as well, this calls for a need of a queue rather than a std::map. This patch still keeps the same lifetime of Camera3RequestDescriptor as before i.e. in the requestComplete(). Previously, a descriptor was extracted from the map and its lifetime was bound to requestComplete(). The lifetime is kept the same by manually calling .pop_front() on the queue. In the subsequent commit, this is likely to change with a centralized location of dropping descriptors from the queue for request completion.

Acquire fences for streams of type Mapped generated by post-processing are not correctly handled and are currently ignored by the camera HAL. Fix this by adding CameraStream::waitFence(), executed before starting the post-processing in CameraStream::process(). The change applies to all streams generated by post-processing (Mapped and Internal) but currently acquire fences of Internal streams are handled by the camera worker. Postpone that to post-processing time by passing -1 to the Worker for Internal streams. Also correct the release_fence handling for failed captures, as the framework requires the release fences to be set to the acquire fence value if the acquire fence has not been waited on.

2021-08-03libcamera: base: class: Don't pass Extensible pointer to Private constructorLaurent Pinchart
The Extensible and Extensible::Private classes contain pointers to each other. These pointers are initialized in the respective class's constructor, by passing a pointer to the other class to each constructor. This particular construct reduces the flexibility of the Extensible pattern, as the Private class instance has to be allocated and constructed in the members initializer list of the Extensible class's constructor. It is thus impossible to perform any operation on the Private class between its construction and the construction of the Extensible class, or to subclass the Private class without subclassing the Extensible class. To make the design pattern more flexible, don't pass the pointer to the Extensible class to the Private class's constructor, but initialize the pointer manually in the Extensible class's constructor. This requires a const_cast as the o_ member of the Private class is const.
