* We buffer output to avoid spamming huge numbers of signals especially when
single lines can be many write calls. This means if an exception is processed
immediately after a print the output from the print may come after the
extension.
* We create both a stubs folder for each specific version, and a 'latest' that
is updated by newer RD versions.
* For development, the stubs will be regenerated any time the git commit hash
changes for development builds.
* In a previous update in 2021 many copyright ranges were truncated
accidentally, and some files have been copy-pasted with wrong years. These
dates have been fixed based on git history and original copyright messages.
* Most of the main entry points that can fail with relevant reasons now has a
way of specifying a message to return with it. This message can be displayed
to the user to give more information or context about an error.
* This prevents unnecessary conversions back and forth between rdcstr and const
char * when going through interfaces. In the OS specific layer this is rarely
an issue because most of the implementations don't convert to rdcstr, but it
is convenient to be able to pass in an rdcstr directly. The few cases where
there's an unecessary construction of an rdcstr is acceptable.
* A couple of places in the public API need to return a string from a global
function, so can't return an rdcstr due to C ABI, so they still return a const
char *.
* Similarly const char * is kept for logging, to avoid a dependency on rdcstr
and because that's one place where unnecessary conversions/constructions may
be impactful.
* If the last refcount on a python lambda/temp function is released when a
wrapping std::function is destroyed in a C++ invoke, we can't destroy it
safely. Instead we queue up that decref and process it the next chance we're
able (which is either when the current execution finishes for a python shell
execution, or on the next function call which handles extensions).
* This by no means replaces PySide2, but it allows python extensions to write
simple UIs without needing to rely on PySide2, which might not be available
(generally all windows builds have it as well as recent binary linux builds,
but local windows builds may not and most linux builds probably won't).
* When the pyside2 we ship was built it accidentally included a small dependency
on Qt5Qml, which we don't distribute so the pyside2 libraries wouldn't load.
* We can generate a tiny stub with the right exports and load it manually from
the PySide2 folder on 32-bit qrenderdoc builds to allow pyside2 to load
subsequently. The stub source is tiny, and added alongside.
* Putting it in the PySide2 folder means that even if someone puts RenderDoc's
build folder in their PATH, our stub Qt5Qml won't break anything because it
won't be loaded. If they put PySide2 in the PATH it might, but then it's their
fault!
