Orphaned datablocks are those which have either:
* 0 users
* A "fake" user only
In the case of the former, they will be quietly discarded from the file on the next
save + reload. Hence, it is helpful to have a view where you can confirm which ones
fall into this category and might be worth saving.
We also include datablocks with a fake user only so that datablocks given a user
above can have that easily turned off again (in case the user makes a mistake).
Another benefit of showing these is that it become easier to remove fake users from
datablocks you no longer want retained without having to hunt for them.
Turned out that I misinterpreted the feature request, plus there are some
minor issues with the commit that would need to be corrected.
After all, I decided to just remove it again as it seems to not be really
useful for the users.
- all mathutils types
- only works on frozen data (so vectors can be used in sets/dict keys)
- uses same method as CPython, (matches hashing a tuple)
D1104 by @juicyfruit with own modifications
Due to changes in the way animation updates were handled,
BL_ArmatureObjects were no longer registering to KX_Scene as animated.
Moguri says: It might have been relying on the deformer update which
moved rom being called on every object in the render step. Now
armature deformers are only updated if they need to be.
Fix T42919 & Fix T42218
The workaround for generated texture coordinates is to be done before
calculating number of elements for attribute, otherwise counter wouldn't
include those attributes.
The idea behind the change is to pre-allocate attribute arrays in advance,
which avoids re-allocation of arrays later for each of meshes being handled.
This reduces peak memory used by Cycles database from 1.3G to 0.9G for
victor.blend from Gooseberry.
It doesn't mean every file will benefit from this change since peak memory
usage is happening in the different places of the rendering code.
Also, unfortunately, attributes export might not cause the peak of render
preparation stage. That said, it's actually object_to_mesh() which causes
the memory to peak in the same test file. So we really need to optimize that
part first in order to get visible results for artists. But in any case it's
now quite easy to track hotspots in Cycles itself which is good.
It's actually a bad level call, but it's inside ifdef block and disabled by
default and only intended to be used for development purposes.
Main idea of this change is to combine statistics coming from Cycles and
Blender during scene synchronization step, to see if further changes are
actually reducing memory footprint.
The method is called vector::free_memory(). Use with care since it'll invalidate
all the pointers to vector memory, all iterators and so on.
Currently unused, but might become handy when clearing unused data.
The commit implements a guarded allocator which can be used by STL classes
such as vectors, maps and so on. This allocator will keep track of current
and peak memory usage which then can be queried.
New code for allocator is only active when building Cycles with debug flag
(WITH_CYCLES_DEBUG) and doesn't distort regular builds too much.
Additionally now we're using own subclass of std::vector which allows us
to implement shrink_to_fit() method which would ensure capacity of the
vector is as big as it should be (without this making vector smaller will
still use all previous memory allocated).
This replaces our own implementation of aligned malloc with system calls,
which depends on which operation system you're on.
This is probably really minor noticeable change, but in the same time it
might reduce amount of wasted memory.
This reverts the change made in 8872cba7e9
which was contributing to actions being lost in some cases [1], even when
they were assigned to those actuaters, which needed them to be able to
function. Now there's one less case where users are needed but were missing :)
Note that this still doesn't solve the core issue where nothing is responsible
for associating actions created for a particular datablock (and not currently
being used in its active action slot, or in the NLA stack) with that datablock.
That issue is the cause of most action disappearances as well as for other problems
(such as renaming bones being unable to fix unreferenced/unused actions) where there
are diifferences between users' mental models and the data model. Proper fixes are
coming soon (restoring fake users here isn't a proper fix, as it only masks the
fundamental mismatch/problem here).

It's really handy to have blender linked against jemalloc because of
much better memory fragmentation handling by that library.
To be noted: if jemalloc library is not found it'll be disabled with
message about that, no compilation error should happen.
This way both BLI_assert() and abort() called directly shouldn't
leave any files in the temp folder.
Previously it was really possible to have gadzillions of files
left over because of assert failures and debug aborts during the
development process.
Draw the grid last with depth masking disabled. That should have no ill
effects otherwise as far as I can tell except from some exceptional
cases (axis lines over grid) but this is hardly annoying.
Generally to properly solve such issues we need to have a better render
pipeline with wire objects/materials being drawn after compositing. This
is not impossible but for now doing it the simple way.
Yes, for me tablets (both wacom and no-name) were again broken - curse X11!
So now, we want ButtonPress, Button1Motion does not work anymore...
Anyway, this patch makes things much cleaner, storing each event type
in its own variable!
Patch by cedricp (Cédric PAILLE) from T43367, thanks a bunch!
Originally the files are coming from ancient early-2.4x epoch, but in
theory such setups might have been re-saved multiple times already with
more recent blender versions.
So the verisoning code is applied on all the files, including very
recent ones.
Bumped subversion, because this check si not really cheap.
We make sure that good values are passed to GetPolygon() and we check that the visual mesh doesn't have a wrong displacement when it passes over a object which has a mesh triangle as compound bound.

The translation and rotation locks subpanel was not used by dynamic physics type to avoid inestability in the application of forces and/or torques. Therefore it is better to remove it from UI (for dynamics) to avoid misunderstandings.
