    "content": "Hi,\n\nIt's been a while since the v1 RFC, and even if I haven't had much time\nto work on this, I thought it's time to send a new version, at least to\navoid anyone testing the old one.\n\nToo many changes to v1 to mention them all (not that I even\nremember...), but a few here:\n\n- Use meson subprojects for pybind11. The public subproject repository\n  didn't have a recent pybind11, so I have pybind11 2.6.0 packaged here\n  in a separate patch.\n\n- Use eventfd to convey events from C++ to Python. This gets rid of\n  multiple issues, e.g. the locking problems and the callback\n  subscriptions.\n\n- simplecamera.py: a \"simple\" camera class which hopefully makes\n  libcamera more natural to use from python (compared to the very c++\n  like API that the basic bindings provide).\n\n- Some new tests:\n  * test.py: simple test that just captures frames and exists\n  * drmtest.py: uses kms++ python bindings to show the captured images\n    on screen.\n  * icam.py: Meant to run in an interactive python session. Uses Qt to\n  * show (possibly from multiple cameras) captured images. One can\n    adjust the cameras & controls via the python shell.\n\nSome clear issues are still present:\n- Memory management, especially related to Requests and FBs is still not\n  clear.\n- Not all control types are supported.\n- There are open parts in the SimpleCamera config sequences. It must be\n  simple, but you also have to be able to do everything, and at the\n  moment it's a bit of a mess.\n\nThis is not a request to review as such, as I know there are plenty of\nthings to fix. I think the best feedback would be on the area of\nthoughts about the API in general, or ideas on how to solve the issues.\n\n Tomi\n\nTomi Valkeinen (4):\n  hack: Camera public destructor\n  HACK: expose Camera* from Request\n  libcamera python bindings\n  py: update pybind11 wrap to 2.6.0\n\n .gitignore                                    |   2 +\n include/libcamera/camera.h                    |   2 +-\n include/libcamera/request.h                   |   1 +\n meson_options.txt                             |   2 +\n src/libcamera/request.cpp                     |   5 +\n src/meson.build                               |   1 +\n src/py/meson.build                            |   1 +\n src/py/pycamera/__init__.py                   |  11 +\n src/py/pycamera/meson.build                   |  38 ++\n src/py/pycamera/pymain.cpp                    | 382 ++++++++++++++++++\n src/py/test/drmtest.py                        | 129 ++++++\n src/py/test/icam.py                           | 154 +++++++\n src/py/test/run-valgrind.sh                   |   6 +\n src/py/test/run.sh                            |   3 +\n src/py/test/simplecamera.py                   | 198 +++++++++\n src/py/test/test.py                           | 210 ++++++++++\n src/py/test/valgrind-pycamera.supp            |  17 +\n .../packagecache/pybind11-2.6.0-wrap.zip      | Bin 0 -> 1456 bytes\n subprojects/packagecache/pybind11-2.6.0.zip   | Bin 0 -> 727287 bytes\n subprojects/pybind11.wrap                     |  10 +\n 20 files changed, 1171 insertions(+), 1 deletion(-)\n create mode 100644 src/py/meson.build\n create mode 100644 src/py/pycamera/__init__.py\n create mode 100644 src/py/pycamera/meson.build\n create mode 100644 src/py/pycamera/pymain.cpp\n create mode 100755 src/py/test/drmtest.py\n create mode 100755 src/py/test/icam.py\n create mode 100755 src/py/test/run-valgrind.sh\n create mode 100755 src/py/test/run.sh\n create mode 100644 src/py/test/simplecamera.py\n create mode 100755 src/py/test/test.py\n create mode 100644 src/py/test/valgrind-pycamera.supp\n create mode 100644 subprojects/packagecache/pybind11-2.6.0-wrap.zip\n create mode 100644 subprojects/packagecache/pybind11-2.6.0.zip\n create mode 100644 subprojects/pybind11.wrap"
