As each extension has it's own package, any modules it includes must be
imported as sub-modules. Warn if extensions are including themselves
in the sys.path as this breaks name-spacing of extensions.
Show these warnings in the add-on & extensions UI.
When the extensions add-on module was loaded before the add-on was
enabled, the module was detected as having changed since it had no
`__time__` member. Loading the add-on would then reload the module.
Resolve by setting the __time__ when first importing.
This is the main merge commit of the brush assets project. The previous
commits did some preparing changes, more tweaks are in the following commits.
Also, a lot of the more general work was already merged into the main branch
over the last two years.
With the new design, quite some things can be removed/replaced:
- There's a unified "Brush" tool now, brush based tools and all special
handling is removed.
- Old tool and brush icons are unsed now, and their initialization code
removed here. That means they draw as blank now, and the icon files can be
removed in a follow up.
- Creation of default brushes is unnecessary since brushes are now bundled in
the Essentials asset library. Icons/previews are handled as standard asset
previews.
- Grease pencil eraser options are replaced by a general default eraser brush
that can be set by the user.
More changes are planned still, see task list issue below.

When a registered class has a non-registered superclass,
rna_info.BuildRNAInfo entered an eternal loop.
The while loop in `rna_info.get_py_class_from_rna` was not mutating the
variables within the loop nor the variable in its condition, meaning it
would loop infinitely if the loop didn't exit in its first iteration.
When yielding registered classes in `subclasses_recurse`, the function
was erroneously checking if the class' superclass was registered rather
than checking the class itself, causing registered classes to be skipped
if their superclass was not also registered. If the class to be found
was skipped, the while loop would not exit in its first iteration and
would thus loop infinitely.
The while loop has been modified to iterate through each base rna type
until there is no further base type.
The `subclasses_recurse` function now correctly checks whether the
subclass is registered, not its superclass, when determining if the
subclass should be yielded.
Besides the fix, no functional changes are expected, the generated
Python API docs remain unchanged.

Previously add-ons were sorted by category & name, remove the category
only sorting by name since the category is no longer displayed and
isn't part of extension meta-data. Now the add-ons are sorted by name
(case insensitive).
Details:
- Store add-ons modules sorted to avoid having to sort on every redraw.
- addon_utils.modules() now returns an iterator.
Changes to an extensions manifest weren't accounted for.
This was particularly a problem for "System" extensions which aren't
intended to be managed inside Blender however the problem existed for
any changes made outside of Blender.
Now enabled extensions are checked on startup to ensure:
- They are compatible with Blender.
- The Python wheels are synchronized.
Resolves#123645.
Details:
- Any extension incompatibilities prevent the add-on being enabled
with a message printing the reason for it being disabled.
- Incompatible add-ons are kept enabled in the preferences to avoid
loosing their own preferences and allow for an upgrade to restore
compatibility.
- To avoid slowing down Blender's startup:
- Checks are skipped when no extensions are enabled
(as is the case for `--factory-startup` & running tests).
- Compatibility data is cached so in common case,
the cache is loaded and all enabled extensions `stat` their
manifests to detect changes without having to parse them.
- The cache is re-generated if any extensions change or the
Blender/Python version changes.
- Compatibility data is updated:
- On startup (when needed).
- On an explicit "Refresh Local"
(mainly for developers who may edit the manifest).
- When refreshing extensions after install/uninstall etc.
since an incompatible extensions may become compatible
after an update.
- When reloading preferences.
- Additional info is shown when the `--debug-python` is enabled,
if there are ever issues with the extension compatibility cache
generation not working as expected.
- The behavior for Python wheels has changed so they are only setup
when the extension is enabled. This was done to simplify startup
checks and has the benefit that an installed but disabled extension
never runs code - as the ability to install wheels means it could
have been imported from other scripts. It also means users can disable
an extension to avoid wheel version conflicts.
This does add the complication however that enabling add-on which is
an extension must first ensure it's wheels are setup.
See `addon_utils.extensions_refresh(..)`.
See code-comments for further details.
The BLT_I18N_MSGID_MULTI_CTXT() macro allows extracting a single
message into up to 16 different contexts. The regex to do that was
slightly wrong because it did not account for the macro potentially
ending with a ",".
The contexts for "New" were also sorted.

Prevent potential problems from untrusted XML (typically themes)
traversing into data outside the intended targets.
From what I can tell it's not currently possible but changes to RNA
could allow for this which would likely go by unnoticed.
Further details in code-comments.
Provide a convenient way to access a writable directory for extensions.
This will typically be accessed via:
bpy.utils.extension_path_user(__package__, create=True)
This API is provided as some extensions on extensions.blender.org
are writing into the extensions own directory which is error prone:
- The extensions own directory is removed when upgrading.
- Users may not have write access to the extensions directory,
especially with "System" repositories which may be on shared network
drives for example.
These directories are only removed when:
- Uninstalling the extension.
- Removing the repository and its files.
The new extension system introduces tags, similar to categories from
legacy add-ons, and permissions. A hardcoded list is supported for
each, available in the docs:
- https://docs.blender.org/manual/en/dev/advanced/extensions/tags.html
- https://developer.blender.org/docs/features/extensions/schema/
This change allows extraction of these new metadata to the translation
files.
In order to disambiguate the new messages, tags use the new "Script"
translation context. Permissions are lower case, so there is a low
risk of collision, and they use the default context.
While the tags are defined per-platform, with extensions.blender.org
being the only one available currently, they are extracted as a single
list.

The issue was that when applying the keyingsets
`Whole Character` and `LocRotScale & Custom Properties` the
enum property of a rigify rig was not keyed.
The reason it was not keyed was just because
it was not specified in the compatible types in the keying set.
The fix is to just add `bpy.types.EnumProperty` to the list.

* Drop the repository - let's combine tags in a single list (per type)
to avoid duplications in the future.
* Give a more sensitive name for tthe property, to avoid tags.tags.
This patch removes the Auto Render option from the compositor. This is
done for the following reason:
- The option didn't really work except in the case of transforming an
object. So it wasn't really reliable.
- It made little sense to use since the introduction of the Viewport
Compositor.
- It had a number of UX issues, including the fact that it can't be used
with animation playback, and the fact that rendering can get in the
way of the UI depending on the preferences for temporary editors.
