Add new function `blo_bhead_is_id_valid_type()` to correctly check the
blend file block type.
File block type codes have four bytes, and two of those are only in use
when these blocks contain ID datablocks (like `"OB\0\0"`). However,
there are other types defined in `BLO_blend_defs.h` that have four
bytes, like `TEST`, `ENDB`, etc.
The function `BKE_idtype_idcode_is_valid(short idcode)` was used to
check for ID datablocks while reading a blend file. This only takes a
2-byte parameter, and thus its result is invalid for the 4-byte codes.
For `TEST` blocks, it would actually consider it a `TE` block, which is
a valid identifier for a Texture. This caused the heap buffer overflow,
as the datablock is not a valid ID, and thus the bytes that were
expected to form an ID name actually encode something completely
different.

Sculpt undo relied on having a mode-changing undo step to properly
apply changes.
However this isn't the case with startup files or when mixing
global undo steps with sculpt (see T82851, also fixed).
Undo stepping logic follows image_undosys_step_decode_undo.
This is basically done by ignoring override operations from old override
affecting ID pointer properties, when the new (destination) one is not
NULL.
Fix T86501: New object added to overridden collection doesn't show up in linking file on Resync.
This is more of a work-around actually, since there is no real way to
fix the issue in a fully automated and consistent way, it is caused by
older blender files being saved with 'broken' overrides.
WARNING: This cannot ensure that some purposedly edited/overridden ID
pointer properties won't be lost in the process.
Code would end up freeing some of the newly created overrides, which
were assigned to the matching linked ID's `newid` pointer, accessed
again further down the code.
Note that this is not a normal expected situation, and it won't give a
proper resync result anyway, but it might happen in some complicated
corner cases, and also quite often when dealing with older .blend files.
In some cases (advanced, low-level), we also want to remap pointers like
`ID.newid` or `ID.orig_id`.
Only known case currently is `id_delete`, to avoid leaving potential access to freed memory. See next commit and T86501.
Baking to Vertex Colors would always bake to sculpt vertex colors (if
such a layer is present) even if those are not enabled in the
experimental preferences. This would bake without an error but leave the
user without a result to look in the viewport.
Now check if sculpt vertex colors are enabled and only bake to them in
that case.

This patch fixes a visual bug related to connecting an output socket to
a Multi-Input Socket, that already has a link to that same output.
In this case, the drag link got a new index and snapped to a new
position. This path makes the drag link snap to the same position as the
first link between the two sockets.

RNA would send property update notifiers with the owner ID as `reference` data.
Since above's commit we'd only send the notifiers to editors if the reference
data address matches the space's address. So editors wouldn't get the notifiers
at all.
The owner ID for space properties is always the screen AFAIK. So allow
notifiers with the screen as reference to be passed to editors as well, think
this is reasonable to do either way.
For example, steps to reproduce were:
* Open Asset Browser
* Mark some data-blocks of different types as assets (e.g. object & its
material)
* Switch between the categories in the Asset Browser. The asset list wouldn't
be updated.
When adding a notifier, `reference` data can be passed. The notifier system
uses this to filter out listeners, for example if data of a scene changes,
windows showing a different scene won't get the notifiers sent to their
listeners.
For the `NC_SPACE` notifiers, a number of places also passed the space as
`reference`, but that wasn't used at all. The notifier would still be sent to
all listeners in all windows (and the listeners didn't use it either). Causing
some unnecessary updates (e.g. see ed2c4825d3).
With this commit, passing a space will make sure the notifier is only sent to
that exact space. Some code seems to already have expected that to be the case.
However there were some cases that passed the space as `reference` without
reason, which would break with this commit (meaning they wouldn't redraw or
update correctly).
Corrected these so they don't pass the space anymore.
Steps to reproduce were:
* Open an Asset Browser
* "Mark Asset" on some data-block
* Change the Asset Browser into a different editor (not File Browser!)
* "Clear Asset" on the data-block again, or mark another asset
* Change back to the Asset Browser, it will show an outdated list
Now the file-browser reloads local file data after spaces were changed. Note
that the current notifier code doesn't limit the space-change notifiers to the
affected spaces, so changing any visible space will trigger this. That's an
issue to be fixed separately.
The check for undo-depth increment/decrement assumed a newly loaded
window manager would have a different pointer.
This broke bl_animation_fcurves test indirectly,
the change to undo-depth caused the redo panel to attempt to popup
in background mode - which isn't supported.
Now the pointer is unchanged, the undo-depth is assumed to match
the value used when calling the operator.
The undo-depth is now properly maintained between file loads,
which is an improvement on the original behavior which reset it.
Keep the pointer location from the initial window-manager
between file load operations.
This is needed as the Python API may hold references to keymaps for e.g.
which are transferred to the newly loaded window manager,
without their `PointerRNA.owner_id` fields being updated.
Since there is only ever one window manager, keep the memory at the same location so the Python ID pointers stay valid.

Ref D10690
Previously many operations would run on file load, even if the file
did not load. Pre/post load handlers were called, timers canceled,
all undo data freed, editors exited ... etc.
Now keep the blend file in it's current state.
This simplifies updating this area of code as there is one less
possible situation to account for.
Currently file loading performs almost all reloading logic
even in the case loading the file fails, causing the file to be in
a state that isn't well defined: undo is cleared, timers are canceled &
scripts are re-registered.
- Don't set G.relbase_valid until the file is loaded.
- Remove unnecessary string pointer comparison.
- Remove unused filename being passed to 'setup_app_data'.
`BKE_lib_override_library_main_resync` uses
`LIB_TAG_LIB_OVERRIDE_NEED_RESYNC` tags set by RNA override apply code,
and perform detection for the remaining cases (those were new overrides
need to be created for data that was not present before in the library).
And then it actually resync all needed local overrides.
Part of T83811 & D10649.
We can fairly easily detect some resync-needed cases when applying the
overrides operations on a Pointer RNA property.
This should cover all cases where an existing override's ID pointer is
changed in its linked data.
We still have to add code to detect when a not-yet-overridden linked ID
needs to become overridden (because its relations to other data-blocks
changed in a way that requires it).
Part of T83811 & D10649.
Rather than letting the `TreeElementAnimData` constructor take an ID from which
we get the animation-data based on an assumption on how it's stored, let the
constructor take the animation-data directly. That way we further centralize
the assumptions on the data passed to the element creation to
`tree_element_create()`.
The following commit will add a comment explaining the plan to entirely get rid
of those assumptions in the future.
There was an implicit assumption that tree element types using the new code
design set their name on creation. Use an assert to make this explicit. See
f59ff9e03a, which was an error because of this broken assumption.
Caused by 2e221de4ce in combination with 4292bb060d.
In the former I forgot to set the name for NLA actions in the new code design,
in the latter I made it an assumtion that tree element types using the new
design set the name.
The following commit will make this assumption explicit with an assert.
When loading a file with an asset browser open, and it showed a custom asset
library that can't be found currently (e.g. because the file is from somebody
else), the `BLI_assert(0)` in `rna_FileAssetSelectParams_asset_library_get()`
would fail.
There was code to handle this case already, but unlike I thought it didn't run
right after file read. Now it does.
The multi-input-socket cannot be connected to the same socket twice currently.
However, it is still possible to achieve this using an intermediate reroute node.
In this case the origin socket should be listed twice in the `linked_sockets_` list.
Higher level functions can still deduplicate the list of they want.
This commit adds an operator to the RMB-menu "Copy Full Data Path“,
to copy the full RNA path to the clipboard. It aims to complement
"Copy Data Path“, which only copies the part of the path that is needed
for drivers, but for writing addons, etc. it is useful to have an option that
gives the full data path.
Similar patch have been submitted before, see D763 and D2746
This time I did not split the operator (as D2746) and does not contain the UI reorganization (as D763)
Note, the fixes from D2746 were committed in rB09eac0159db8 so that patch can be closed.
