In some instances, the number of control vertices of a hair could change mid-frame.
Cycles would then be unable to calculate proper motion blur for those hairs. This adds
interpolated CVs to fill in for the missing data. While this will not necessarily result in
a fully accurate reconstruction of the guide hair, it preserves motion blur instead of disabling it.

Custom drawing functions were used just to control property display.
Move to poll function.
|
|
This allows operators to filter out properties from the
auto-generated draw functions.
Some custom draw functions can move to using this.

We were using int's for bool arguments in BKE,
just to avoid having wrapper functions.

The easy ones - there some much, much trickier to tackle there...

Notes:
* Really need to address RNA setters case, end up adding way too much
G.main here these days... :/
* Added Main pointer into bAnimContext, helps a lot in anim code ;)
|
|
|
|
Note that in some cases, this only moves the G.main case to somne other
places - in particular, RNA getters/setters are becoming annoying here...

This makes code closer to id_override/assent-engine ones, which
introduce a new type of linked data, and hence reserve
ID_IS_LINKED_DATABLOCK to real linked datablocks.
|
|
Means we can have a version of this function that returns the button
and avoids returning a struct that often isn't used.

Practically all access to enum data is read-only.

Cyclic extrapolation is implemented as an f-curve modifier, so this
technically violates abstraction separation and is something of a hack.
However without such behavior achieving smooth looping with cyclic
extrapolation is extremely cumbersome.
The new behavior is applied when the first modifier is Cyclic
extrapolation in Repeat or Repeat with Offset mode without
using influence, repeat count or range restrictions.
This change in behavior means that curve handles have to be updated
when the modifier is added, removed or its options change. Due to the
way code is structured, it seems it requires a helper link to the
containing curve from the modifier object.

Regression from rBa7b3047cefcbf, to be backported to 2.79.
Like... seriously... :|

This will allow much finer controll over how we copy data-blocks, from
full copy in Main database, to "lighter" ones (out of Main, inside an
already allocated datablock, etc.).
This commit also transfers a llot of what was previously handled by
per-ID-type custom code to generic ID handling code in BKE_library.
Hopefully will avoid in future inconsistencies and missing bits we had
all over the codebase in the past.
It also adds missing copying handling for a few types, most notably
Scene (which where using a fully customized handling previously).
Note that the type of allocation used during copying (regular in Main,
allocated but outside of Main, or not allocated by ID handling code at
all) is stored in ID's, which allows to handle them correctly when
freeing. This needs to be taken care of with caution when doing 'weird'
unusual things with ID copying and/or allocation!
As a final note, while rather noisy, this commit will hopefully not
break too much existing branches, old 'API' has been kept for the main
part, as a wrapper around new code. Cleaning it up will happen later.

Reported by Andy Goralczyk (@eyecandy) over IRC, thanks!
Simply nuke all that poor broken custom one-by-one handling in
object_relations.c code, and use highly complex but powerful and
well-tested BKE_library_make_local() in all cases of MakeLocal!
ID management, especially related to linking, is very hairy matters,
better to have as few as possible core functions managing all the dirty
details. ;)

Properly remap nodes' pointers to copied IDs in copied ntrees.
Note that this only affects root trees, node groups are not concerned
here, since they are assumed to be reusable chunks and hence *not*
duplicated.

The absence of datablock properties "will certainly be resolved soon as the need for them is becoming obvious" said the [[http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.67/Python_Nodes|Python Nodes release notes]]. So this patch allows Python scripts to create ID Properties which reference datablocks.
This functionality is implemented for `PointerProperty` and now such properties can be created with Python.
In addition to the standard update callback, `PointerProperty` can have a `poll` callback (standard RNA) which is useful for search menus. For details see the test included in this patch.

`cd_flag` tends to be used for CustomData flags in mesh area, while for
library_query those are rather callback flags...
|
|
Use Main->relations in BKE_library_foreach_ID_link(), when possible
(i.e. IDWALK_READONLY is set), and if the data is available of course.
This is quite minor optimization, no sensible improvements are expected,
but does not hurt either to avoid potentially tens of looping over e.g.
objects constraints and modifiers, or heap of drivers...

Was a waaaaayyyyy to much generic name for such a specific func, renamed
to much more descriptive BKE_libblock_relink_to_newid().
In near future (few weeks, to limit as much as possible silent mismatch
in branches), will rename BKE_libblock_relink_ex to BKE_libblock_relink,
this is the real generic data-block relinking func!
|

This aims at always ensuring that ID.newid (and relevant LIB_TAG_NEW)
stay in clean (i.e. cleared) state by default.
To achieve this, instead of clearing after all id copy call (would be
horribly noisy, and bad for performances), we try to completely remove
the setting of id->newid by default when copying a new ID.
This implies that areas actually needing that info (mainly, object editing
area (make single user...) and make local area) have to ensure they set
it themselves as needed.
This is far from simple change, many complex code paths to consider, so
will need some serious testing. :/
|
|
We have to clear `newid` of all datablocks, not only object ones.
Note that this whole stuff is still using some kind of older, primitive
'ID remapping', would like to see whether we can replace it with new,
more generic one, but that's for another day.
|
|
Issue here was that py API code was keeping references (pointers) to the
liniked data-blocks, which can actually be duplicated and then deleted
during the 'make local' process...
Would have like to find a better way than passing optional GHash to get
the oldid->newid mapping, but could not think of a better idea.

Material linking might and does change the way how drawObject is calculated
but does not tag drawObject for recalculation in any way.
Now use dependency graph to tag draw object for reclaculation. Currently do
this using OB_RECALC_DATA taq since tagging is not very granular yet. In the
future we can introduce ore granular tagging in the new dependency graph
easily.
Simple and safe for 2.78a.

Was using a bunch of different spellings, mostly "data-block" though, so went with that one (would have been my #1 choice anyway ;) )

Another great example of inconsistency in usercount handling - dupli_group was considered
as refcounted by readfile.c code (and hence by library_query.c one, which is based on it),
but not by editor/BKE_object code, which never increased group's usercount when creating
an instance of it etc.
To be backported to 2.78.
|
|
This is mainly required for the new dependency graph where non-object
datablocks are a part of dependency graph.
This solves issue when making mesh shared by multiple objects a single
user one.

Wasn't copying back local view bytes to object after changing layer.
Steps to reproduce were:
* Split 3D view in default startup.blend
* Enter local view in one of the 3D views
* Move default cube to different layer *in the other 3D view* (the one that's not in local view)
* Try transforming object from 3D View that's in local view (should lag)

Totally stupid to not pass it, and then let (some) BKE_foo_make_local() use G.main!
Note: unused for now, much more refactoring still to come in make_local area!

Now test_object_materials only handles one object. New test_all_objects_materials
checks the whole bmain->object list for cases where it is actually needed.
Should avoid some useless looping over all objects!

Idea is to replace hard-to-track (id->lib != NULL) 'is linked datablock' check everywhere in Blender
by a macro doing the same thing. This will allow to easily spot those checks in future, and more importantly,
to easily change it (see work done in asset-engine branch).
Note: did not touch to readfile.c, since there most of the time 'id->lib' check actually concerns the pointer,
and not a check whether ID is linked or not. Will have a closer look at it later.

Now CD_SHAPEKEY_INDEX customdata is stored in edit-mode when hooks and vertex parents are used.
This also fixes a bug where undo would loose key-index data.
Move to structs for BM_mesh_bm_to/from_me to avoid passing many argument, which mostly aren't used.

This commit:
* Fixes bad handling of 'stop iteration' (by adding a status flag, so that we can actually
stop in helper functions too, and jumping to a finalize label instead of raw return, to
allow propper clean up).
* Adds optional recursion into 'ID tree' - callback can also decide to exclude current id_pp
from recursion. Note that this implies 'readonly', modifying IDs while recursing is not
something we want to support!
* Changes callback signature/expected behavior: return behavior is now handled through flags,
and 'parent' ID of id_pp is also passed (since it may not always be root id anymore).

increase 'real' user count.
This has several benefits:
* User count remains coherent, regardless of the order in which you use 'user_one' & real refcounting users
(i.e. if you add to group, and then link in scene, or the reverse, you now always get same final user count).
* Avoids the need to check for potential 'user_one' extra user in count in several places in code (e.g. when
making IDs single users...).
* Users won't wonder why they cannot make 'single user' and ID even though its user count shows '2'!
* readfile.c now always uses code from BKE's library.c when modifying id->us. Which means we can consider
(asside from assignment during initialization) that id->us is read-only outside of library.c context.
Note that this commit reverts previous one (rB6b1d77a8052b) - please **do not** backport this one in 2.77.

object could be removed from group.
Similar cause as in T47482, we used to have poor handling of 'user_one' cases of ID usage,
leading to inconsistent behavior depending on order of operations e.g.
Here, was object used by a group but not linked in any scene - once linked in scene,
their usercount would be 2, leading to 'making single copy', when it's actually not needed.
We now have better control here, so let's use it!
Note that other ID 'make single user' code will likely need similar fix (Images, etc.).
Safe to be backported to 2.77.
