No reasons to keep the new ID pointer as parameter here.
Part of T71219.
|
|
Note that possibility to pass the new ID pointer as parameter was kept,
as this is needed for some rather specific cases (like in depsgraph/COW,
when copying into already allocated memory).

Particularly useful now that we can dynamically generate volume using
modifiers. Not exposed in the user interface currently, but it can be used
by add-ons that need to export an entire scene including volumes.

It used to be an `int mode`.

In the graph editor there is a panel that says "Active Keyframe" for
numerically editing a keyframe's values, but in the code there is no
concept of the "active keyframe." Since this is a useful concept to
have for some other features anyway, this commit adds an active
keyframe index value to FCurves. It also displays it with a theme
color for the active vertex (which didn't exist before) if the
FCurve is active.
The active keyframe in the graph editor is treated similarly to the
active vertex in the 3D view. It is the keyframe most recently selected
with a single click, and it is always selected.
For now, the only real functional change is that the active keyframe
appears in white and it should be more predictable which keyframe is
being edited in the sidebar panel.

code.
Besides the NodeTree case (which remains unchanged), the localize code
is only used in one place (to generate previews of shading data-blocks).
This commit introduces a new `LIB_ID_CREATE_LOCAL` option for ID
creation/copying, which essentially implements the behavior of the
removed `BKE_XXX_localize()` functions into regular mainstream ID copy
code. When this option is set:
- new ID is tagged with `LIB_TAG_LOCALIZED`;
- Some ID copying callbacks have specific behaviors, mainly the root
nodetree of shading IDs gets duplicated with specialized
`ntreeLocalize()` function.
Note that I would not consider getting rid of `ntreeLocalize` for now,
this function is recursive, which should ideally never happen within ID
management copying code (this introduces all kind of complications).
No behavioral change expected from this commit.

Add a specific flag for nodetree deep-copy special localization code.
And add a new `LIB_ID_CREATE_LOCALIZE` flag, similar to
`LIB_ID_COPY_LOCALIZE`, for creation purposes.
No behavioral changes expected here.

This code gets called before do_version can fix that, so we have to work
around it for now.

When the limit surface is disabled OpenSubdiv generates a set of linear
patches which are only C0 continuous, not C1. This makes it impossible to
evaluate derivatives at vertices which, in this mode, are by definition put
at boundaries of patches. Normals are calculated from those derivatives.
Solution is to disable normal calculation and let it be done downstream, as
for other modifiers. This limitation is also the reason that non feature
adaptive subdivision is badly suited for GPU evaluation.

During the refactor, this feature was removed by error.
When this option is enabled, only the frames with a keyframe are displayed in Draw mode. This is used when fill an animation to paint only in the frames with real drawing.

Apply the De Casteljau algorithm to split the Bèzier curve at the X
coordinate where the new key is inserted, and uses the result to update
both the newly inserted and surrounding handles.
For curves that use Auto keyframes this has been largely addressed by
the new algorithm from D2884. This commit extends this to non-auto
handles.
This code is heavily based on D3172 by Alexander Gavrilov (@angavrilov).

Remove the need for a temporary allocated path.
|
|
Changes didn't account the case when mkdtemp failed.
Previously the copying the string wasn't needed in this case.
|
|
Functionality was hard to follow as the meaning of fullname
depended on basename being NULL or not.
- where_is_temp is now only responsible for finding the temp directory.
- Split out tempdir_session_create into it's own function
that wraps mkdtemp.
- Rename basename to tempdir, fullname to tempdir_session.
|
|
Avoid multiple static variables with odd names,
instead keep them all in one struct, expand their names for clarity.
|
|
While this works with GCC, printing NULL strings is undefined behavior.
|

These were printf's, disabled by a define that could be uncommented.
Use logging since this can be useful when investigating any issue
with paths not being found at the expected location.
Without this any problem finding app-templates, Python's installation,
icons ... etc are quite difficult to troubleshoot especially on systems
without access to system-call tracing.
To use this run:
blender --log "bke.appdir" --log-level 3
|
|
Initialize ImBuf (and color-management) after passing arguments
that set environment variables such as `--env-system-datapath`
This also fixes a bug where BKE_appdir logging failed since it was
called before the `--log` argument was passed.
Add asserts so this doesn't happen again.
|
|
- ver -> version.
- env -> env_path.
|
|
Internally appdir functions would test if a path exists,
returning false if it doesn't, leaving the string set instead
of clearing it.
This is error prone as invalid paths could be used accidentally.
Since BKE_appdir_folder_id_user_notest & BKE_appdir_folder_id_version
depend on this, add a 'check_is_dir' argument so the path can be used
even when the directory can't be found.
|
|
Change `test_path` function so:
- Joining paths calls a function instead of being performed inline.
- Optional NULL paths must always be ordered last (easier to follow).
Other minor changes:
- Remove FIXME comment is it's handled properly by BLI_path_join.
- The wrong size was being used copying into `targetpath`.
|
|
We have our own assert implementation, `BLI_assert()` that is prefered over the
C standard library one. Its output is more consistent across compilers and
makes termination on assert failure optional (through `WITH_ASSERT_ABORT`).
In many places we'd include the C library header without ever accessing it.
|
|
Keep related functionality grouped.

Use doxy syntax & minor improvements.

Revert 76b1a27f96ffe1ec8c5351f34bcc2b9733b4483e since there is no
reason windows should behave differently to other platforms.
This was added so Windows users wouldn't see "/tmp/" in the UI.
Since then the default temporary directory is a blank string,
leave blank on all systems as Python script authors may accidentally
use this instead of `bpy.app.tempdir`.
|
|
This last worked in v2.27 (2003) where all paths were initialized to "/"
which was still checked to initialize the temp directory.
This hasn't been the case since 932e9e831647604e0b129b55e5ab035
where it changed to "/tmp/", then an empty string (current default).
|

v2.4x could cancel loading files that warned of being a newer,
unsupported version.
Remove this logic since it's no longer in use.
|
|
When blend files were loaded with app-templates,
setup_app_data was running before defaults were updated.
This is likely to cause problems with order of initialization
so always update the startup file beforehand.

Define enum `eContextResult` and use its values for returns, instead of
just returning 1, 0, or -1 (and always having some comment that explains
what -1 means).
This also cleans up the mixup between returning `0` and `false`, and `1`
and `true`. An inconsistency was discovered during this cleanup, and
marked with `TODO(sybren)`. It's not fixed here, as it would consititute
a functional change.
The enum isn't used everywhere, as enums in C and C++ can have different
storage sizes. To prevent issues, callback functions are still declared
as returning`int`. To at least make things easier to understand for
humans, I marked those with `int /*eContextResult*/`.
This is a followup of D9090, and is intended to unify how context
callbacks return values. This will make it easier to extend the approach
in D9090 to those functions.
No functional changes.

properly.
Armature freeing would not correctly free its editbone IDProperties.
Add a utils to free the whole list of edit bones, and properly handle
their potential IDProperties.
|
|
Freeing of bones' IDproerties from Armature `free_data` callback would always
attempt to do user refcounting, which should never be done from that code.
This would generate crashes in depsgraph/COW context e.g.
|
|
IDProperties.
So far data management code would simply fully ignore potential ID
pointers in custom properties of edit bones (which are a copy of those
from regular `Bone`). This would lead to all kind of issues, among which
refcounting inconsistencies, missing clearing of data uppon deletion,
etc.
|

Access to this structure will be needed in BKE's armature code.

Trying to open the 2.74 Fishy Cat file would generate endless asserts in
customdata code. This commit refactors and cleans up the code of
`psys_get_dupli_texture` to avoid useless calls and data access, and
validate data before trying to further access it.
No behavioral changes expected here (besides getting rid of the assert).

.blend file.
Relying on pointer addresses across different data-blocks is extremely
not recommended (and should be strictly forbidden ideally), in
particular in direct_link step of blend file reading.
- It assumes a specific order in reading of data, which is not ensured
in future, and is in any case a very bad, non explicit, hidden
dependency on behaviors of other parts of the codebase.
- It is intrinsically unsafe (as in, it makes writing bad code and making
mistakes easy, see e.g. fix in rB84b3f6e049b35f9).
- It makes advanced handling of data-blocks harder (thinking about
partial undo code e.g., even though in this specific case it was not
an issue as we do not re-read neither windowmanagers nor worspaces
during undo).
New code uses windows' `winid` instead as 'anchor' to find again proper
workspace hook in windows at read time.
As a bonus, it will also cleanup the list of relations from any invalid
ones (afaict it was never done previously).

Followup for rB8398050695
This requires moving a few enum definitions to DNA instead of BKE, and
adding default definitions for the two structs the cloth modifier where
the cloth modifier stores its settings. The defaults are also reordered

This simulation area mode moves the active area with the brush. When
enabled, the cloth brush has no restrictions on stroke length, area or
mesh vertex count.
In order to work, this enables PBVH nodes dynamically for simulation as
the stroke location moves and builds the constraints for new nodes
during the stroke. When a node is not inside the simulated area, all the
constraints that were created for it and vertex collisions are not
computed. The simulation limits falloff areas and constraints tweaking
control how the simulated and no simulated nodes blend.
