* This tries to ast parse source that may contain an error.
* We don't try to fully error recover from unlimited problems, but a single
statement that is being edited can be tolerated by commenting out lines around
it
* 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.
* This is not the default python layout but is convenient for sharing the
standard library .zip and include folder with separate binary folders per-
platform. The layout mirrors what we include in the repository.
* This is expected to be in a pyside\ subfolder, with an organisation matching
our default setup.
* We also now copy the shiboken2 python module (if it exists) as required by new
pyside2 versions.
* 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.
* We shouldn't require 'pure virtual' functions in CaptureViewer implementations
in python, so detect when the derived class methods point to the base class
pass-throughs, and skip them in that case.
* We keep parent references when returning child objects via reference/python
object wrappers rather than copying. But when iterating a linked list like the
actions this can produce an incredibly long parent chain and then on
destruction we can stack overflow if the chain is long enough.
* These are temporarily given separate names, to allow them to exist in parallel
with the existing helpers, but in future these will be renamed when the older
helpers are removed.
