2021-07-27utils: ipc: Assign a new gid to proxy workerUmang Jain
Isolated IPAs are forked to a new process by the proxy worker, which shares the same process group. This allows the undesired effect that the proxy worker will receive signals such as SIGINT and will be closed by a Ctrl-C event before the pipeline handlers have been able to fully clean up. Prevent this signal from being delivered to the proxy worker by moving the process to a new process group, matching the pid of the isolated proxy.

2021-06-01utils: ipc: mojo: Error if ControlInfoMap/List doesn't prefix libcameraPaul Elder
The mojo parser is fine if there are types that are used in array/map members that it does not know about. These are usually caught by the C++ compiler, because the generated code refers to unknown types. This feature is necessary for us for supporting FrameBuffer::Plane as an array/map member, since as long as the type has an IPADataSerializer and the struct defined in C++, the generated code will run fine (FrameBuffer::Plane is not defined anywhere in mojom but is used as an array member in IPABuffer). The types that are defined in controls.h (or any header included in ipa_interface.h) will all be compiled by the C++ compiler fine, since the generated files all include controls.h. The types that are there that are not ControlInfoMap or ControlList (like ControlValue) will still fail at the linker stage. For example: struct A { array<ControlValue> a; }; will compile fine, but will fail to link, since IPADataSerializer<ControlValue> doesn't exist. This behavior, although not the best, is acceptable. The issue is that if ControlInfoMap or ControlList are used as array/map members without the libcamera prefix, the compiler will not complain, as the types are valid, and the linker will also not complain, as IPADataSerializer<ControlList> and IPADataSerializer<ControlInfoMap> both exist. However, the code generator will not recognize them as types that require a ControlSerializer (since mojo doesn't recognize them, so they are different from the ones that it does recognize with the libcamera namespace), and so the ControlSerializer will not be passed to the serializer in the generated code. This is the cause of the FATAL breakage: FATAL IPADataSerializer ipa_data_serializer.cpp:437 ControlSerializer not provided for serialization of ControlInfoMap Since ControlInfoMap and ControlList are the only types that will run into this issue, we solve this by simply detecting if they are used without the prefix, and produce an error at that point in the code generator. As the code generator stage no longer has information on the source code file and line, we output the struct name in which the error was found (ninja will output the file name).

Moving the core.mojom documentation to its corresponding .cpp file (core_ipa_interface.cpp). This will allow Doxygen to generate the documentation for IPABuffer, IPASettings and IPAStream structures. Since the .mojom files are placed in include/ directory, the .cpp file will live in $sourcedir/src/libcamera/ipa/ - which can also contain documentation for other mojom generated IPA interfaces in subsequent commit. Also hide the constructors in generated IPA interface from doxygen, via #ifndef __DOXYGEN__.

The Commit class and subclasses were reworked in commit 4f5d17f3a4f5 ("utils: checkstyle.py: Make title and files properties of commit class") with the introduction of members of the base class that were meant to be protected (not used externally, but accessible by subclasses). They have been named with a '__' prefix for this purpose, which was a bad choice as Python effectively replaces a leading '__' with a literal '__classname__' prefix to make them private (https://docs.python.org/3/tutorial/classes.html#private-variables). The members accessed in the derived classes are thus different from the ones in the base class. Fix this by replacing the double underscore prefix with a single underscore, which is a "weak internal use indicator" (as specified in https://www.python.org/dev/peps/pep-0008/), closer to the protected access specifier of C++.
