2024-02-28meson_options: Autodetect pycamera supportKieran Bingham
The pycamera was defaulted to be disabled due to a requirement on a specialised branch of the pybind dependency. This requirement on a subproject has been removed and we can now build the pycamera component provided that the distribution packages pybind directly which is common. Enable the pycamera build option to be selected automatically when both Python and pybind are detected on the system.

2024-02-28README.rst: Report py dependenciesKieran Bingham
The Python bindings were supported by a subproject when they were first contributed to be able to directly make use of the smart pointers branch. This requirement has now been removed to prefer using released versions of pybind11 directly, however the README.rst was not updated to reference and reflect this. Update the README.rst to report the pybind11 package which needs to be installed to make use of the optional Python bindings component.

Versions of the ISP differ in the processing blocks they include, as well as in the implementation of some of those blocks. In particular, they have different numbers of histogram bins oe AE statistics cells. The algorithms take these differences into account by checking the ISP version reported by the driver.

2024-01-25libcamera: object: Add and use thread-bound assertionLaurent Pinchart
Several functions in libcamera classes are marked as thread-bound, restricting the contexts in which those functions can be called. There is no infrastructure to enforce these restrictions, causing difficult to debug race conditions when they are not met by callers. As a first step to solve this, add an assertThreadBound() protected function to the Object class to test if the calling thread context is valid, and use it in member functions of Object subclasses marked as thread-bound. This replaces manual tests in a few locations. The thread-bound member functions of classes that do not inherit from Object are not checked, and neither are the functions of classes marked as thread-bound at the class level. These issue should be addressed in the future. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Milan Zamazal <mzamazal@redhat.com>
2024-01-25libcamera: object: Document and ensure Object deletion constraintsLaurent Pinchart
Object instances are meant to be deleted from the thread they are bound to, and this requirement is documented. There are however exceptions to the rule, as threads may be stopped and restarted, with objects bound to them not being deleted and recreated for every stop/restart cycle. Bound objects may therefore need to be deleted after the thread has stopped, making it impossible to use Object::deleteLater(). Document the lifetime requirements more precisely, and enforce them with an assertion.

Starting a timer from the wrong thread is expected to fail, and we test this in the timer-thread unit test. This is however not something that a caller is allowed to do, and libcamera will get assertion failures to catch this invalid usage. The unit test will then fail. To prepare for this, split the unit test in two, with a test that is expected by meson to succeed, and one that is expected to fail. The assertion will then cause an expected failure, making the test suite succeed. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Milan Zamazal <mzamazal@redhat.com>

2024-01-25libcamera: thread: Ensure deferred deletion of all objects before stoppingLaurent Pinchart
Objects can be scheduled for deletion with Object::deleteLater(), which queues a deferred deletion to the thread's event loop. As the deleteLater() function is meant to be called from a different thread, this may race with thread termination, and deferred deletions queued just before calling Thread::exit() may not be processed by the event loop. Make sure they get processed when finishing the thread, before stopping. This eliminates the race condition that occurs when calling Object::deleteLater() followed by Thread::exit() from the same thread. Calling deleteLater() from neither the thread the object is bound to or the thread calling Thread::exit() is still inherently racy. The change fixes a failure in the object-delete unit test.

2024-01-09utils: ipc: Update mojoLaurent Pinchart
Update mojo from commit 9be4263648d7d1a04bb78be75df53f56449a5e3a "Updating trunk VERSION from 6225.0 to 6226.0" from the Chromium repository. The update-mojo.sh script was used for this update.

2024-01-09utils: ipc: generate.py: Disable attributes checkerLaurent Pinchart
The attributes checker ensures that .mojom files don't contain unknown attributes. These check fail with the custom 'skipSerdes' and 'async' libcamera attributes. Ideally the list of supported attributes should be extended, but that can't easily be done without modifying the mojo sources that we try to keep identical to the upstream version to make updates easier. Disable the attributes checker completely for now to fix this issue. While at it, fix an indentation issue reported by checkstyle.py.
