The only remaining code in source/blender that must be compiled as C is now datatoc generated code and the DNA defaults that use designated initializers. Pull Request: https://projects.blender.org/blender/blender/pulls/134469

/**
|
|
* Called from #do_versions() in `readfile.cc` to convert the old 'IPO/adrcode'
|
|
* system to the new Layered Action system.
|
|
*
|
|
* Note: this *only* deals with animation data that is *pre-Animato*, and
|
|
* upgrades it all the way past Animato to modern Layered Actions and drivers.
|
|
* Actions that are already Animato actions are ignored, as they are versioned
|
|
* elsewhere (see `animrig::versioning::convert_legacy_actions()`). This is admittedly
|
|
* weird, but it's due to the fact that versioning pre-Animato data requires
|
|
* creating new datablocks, which must happen at a stage *after* the standard
|
|
* versioning where the simpler Animato-to-Layered upgrades are done.
|
|
*
|
|
* The basic method used here, is to loop over data-blocks which have IPO-data,
|
|
* and add those IPO's to new AnimData blocks as Actions.
|
|
* Action/NLA data only works well for Objects, so these only need to be checked for there.
|
|
*
|
|
* Data that has been converted should be freed immediately, which means that it is immediately
|
|
* clear which data-blocks have yet to be converted, and also prevent freeing errors when we exit.
|
|
*
|
|
* \note Currently done after all file reading.
