- Use "vert" in variable names instead of "i"
- Declare variables where their values are assigned
- Use float3 instead of pointers
- Avoid empty checks in loop by assigning span differently
The issue has been introduced by #122105
The image save operator does exactly the thing which was not supported by
the change and was not caught during development or view: it acquires and
releases image buffers while a render result of the Image data-block is
held acquired.
The solution is to implement a simple user-counter for the render result.
Currently it is only used by the image's render result acquire/release API,
as it is the most important case for now. The render pipeline uses its own
way of protecting the result, for which the user counter is not needed.

A few ID types are considered as 'never unused' in Blender (UI related
ones, the Libraries and the Scenes). Local IDs of this type are always
considered as used, even if no other ID links to them.
This was previously fairly weekly defined and implemented (mainly in the
writefile code and the 'tag unused' libquery functions).
This commit formalize this characteristic of ID types by adding a new
`IDTYPE_FLAGS_NEVER_UNUSED` flag, and using this in the few places in
the code that handle unused IDs.
Splash screen notification text:
- When starting in "Offline mode" with repositories with installed
packages enabled, the text is clickable unless launched with
`--offline-mode`, the tooltip notes that the command line setting
can't be changed at run-time.
- Don's show anything if there are not extensions installed.
Preferences:
- Don't show the welcome message on preferences if:
- Blender is online.
- The message was dismissed.
- There are no enabled remote repositories.
- The option to enable extensions.blender.org has been replaced with
a button that switches to the "System" tab where Online Access
can be enabled.
Also expose bpy.app.online_access_override needed for the UI to check
if online access was disabled using command line arguments.
Blender shows invalid links in red in the node editor. However, it's not always
obvious why some links don't work, especially for beginners. This patch adds
additional information for every invalid link on the node that it links to.
The following error messages are added:
* Invalid link because of missing implicit conversions.
* Link cycle in node tree.
* A link from a field to a socket that does not support fields.
* Using the same menu on multiple Menu Switch nodes.
Currently, there are some per tree-type special cases in the link validation code.
In the future, this should be moved to tree type specific callbacks.

Conversion of compositor node tree to operation is done in a job thread,
and the main thread might modify the image data-block at the same time.
This change fixes it by making it so compositor uses acquire/release
semantic for the image data-block, and making it so the image locks its
render result, preventing other threads from modifying it.

These remain linked, so data remains to be read/loaded from the packed
version from the library (making this a useless and wasteful
duplication, also changes could be perceived as lost). Tooltip was also
reading "Unpack all files packed **into this .blend** to external ones",
so that bring it in line with the tooltip.
This came up in #122033

This introduce a new "secret" per-repository property of type password
as described by #121856.
A token or secret may be used by some non blender.org repositories.
This only shows for remote repositories and is shown in the
"Add Remote Repository" popup.
This commit doesn't implement sending to token to the server which will
be implemented separately.

Fixes#107880.
When making a linked asset local, you typically wouldn't want this new
data-block to suddenly be part of the asset libraries this file is in. To the
user it seems like making such a data-block local also implicitly makes it an
asset. Appending an asset already handles this, and clears the asset data by
default.
This patch modifies the `bpy.types.ID.make_local()` method, as well as all
internal calls to the make local functions, so that asset data is cleared by
default. The Python method has a new `clear_asset_data` parameter (optional,
true by default). Maybe this should not be optional.

For the brush assets, this mechanism makes brush, texture, node tree and
image datablocks editable even when library linked.
This commit should introduce no functional change yet, as the code to
actually tag such libraries as editable will come later.
* These libraries and their datablocks are preserved when loading a new
blend file, much like the UI can be preserved.
* Operators that create new datablocks to be assigned to such datablocks
will put the datablocks in the same library immediately. This was
implemented for datablocks relevant for brush assets.
* RNA does not allow assignment of pointers from such linked datablocks
to local datablocks.

* Linked datablocks should not point to local datablocks.
* Main datablocks should not point to non-main datablocks.
This is checked now both in the poll function for UI lists, and in the
pointer assignment code used by the Python API.
Image's render result might get freed from another thread while the
compositor is running.
Add an utility function which invokes callback on the image's stamp
data from a thread-guarded block.

Image operation's get_im_buf() function was not thread-safe:
- It had TOCTOU issue around calculating multi-layer indices and
requesting to load the image buffer.
- It accessed render result, render layer and pass pointers without
any thread guards.
This change moves all the logic needed to access the image buffer
into a single function with proper guards around the access. The
result is user-counted, so it is usable in a thread even if another
thread modifies the image.
The is still potential TOCTOU in the compositor since the image is
acquired twice: once from init_execution(), and once from the
determine_canvas(). It could cause issues if image resolution is
changed between these calls. It is still to be looked into.

The `Layer::get_frame_duration_at` was not working for frames
with a fixed duration. While this is not an issue at the
moment (because fixed duration frames are not exposed
yet), this would have been broken in the future.
This fixes the issues, cleans up the code a bit, and also
adds regression tests.
Pull Request: https://projects.blender.org/blender/blender/pulls/122052
There were multiple places in the GPv3 code that assumed that the
frame key is equivalent to the start frame of the frame with that key.
But this is not the case. The `FramesMapKeyT` is either the start frame
*or* the end frame (for frames with fixed duration).
This adds a new function `start_frame_at` that returns the start frame
number of the frame at `frame_number` or -1 if no such frame exists.
One place needed the index into sorted keys (for onion skinning) so
this was replaced with a new function `sorted_keys_index_at`.
With these changes, `Layer::frame_key_at` is now a private method.
Pull Request: https://projects.blender.org/blender/blender/pulls/122045
Other code also uses the suffix `T` to indicate that this is a type.
Note that `FramesMapKeyT` is just an `int` but with a very specific
meaning. Hence the alias to avoid confusions.
- Directly check for vertices with two edge neighbors instead of looping
- Use arrays of C++ types as return values
- Use lambda to avoid repetition for each edge vertex
- Use `edge_other_vert` utility
`mesh_final` isn't really the final mesh but the "current" mesh. Adding the
extra word here isn't helpful. This also helps to reduce the size of the diff
in #119968 where the mesh variables have much smaller scopes.
After recent commits, the .cc file is only used for actual object data
evaluation in the depsgraph, and the header is only used for the old
DerivedMesh data structure that's still being phased out.
Mesh object evaluation is unrelated to DerivedMesh nowadays. Change the
name to something similar to the other evaluation functions called in
BKE_object_handle_data_update.
Grouping the legacy DerivedMesh code in the same place helps keep
the actively maintained code clearer and clarifies what we are hoping
to remove in the future.
Move to a file with the more consistent "mesh_legacy" naming, out of the
modifier evaluation code which has nothing to do with this anymore. That
file can be renamed in a separate step.
Using a non-virtual derived struct for polymorphism is error prone,
especially combined with the requirements of DNA. Instead, use a
separately allocated runtime struct as done for many other DNA structs.
In a followup commit, the remaining runtime members of `PreviewImage`
could be moved to the new runtime struct.

This commit prevents considering Scenes (and a few other ID types, like
WindowManager or Library) as being part of liboverride hierarchies.
Having collections, objects, obdata etc. depend on a Scene ID is
typically not considered as a valid setup for linked data.
And in any case, Scenes are not officially supported for liboverrides
currently.
In the case of #121410, where a driver of the armature object was using
the Scene ID, it will simply keep that scene reference pointing to the
linked scene, instead of overriding the whole scene.
Code checking whether an ID should be considered as part of the
currently processed liboverride hierarchy or not was very similar all
over the liboverride code.
It is now deduplicated into two util functions, which helps ensuring
coherence in these checks, and future potential changes in this
filtering process.
NOTE: While no pratical changes are expected form user PoV with this
refactor, technically it does modifies the behavior in some cases (added
checks).
