Am not sure whether we want to support that at some point, but at least
if we don’t, make it safe and get out of copy code early, previously
trying to duplicate workspace through BKE_id_copy() would have given a
very bad a broken result...
`id_single_user()` was still code from older ID management, now we can
use modern code to handle animdata duplication for us (which allows to
keep handling of nasty sub-data ID horrors like nodtrees in a single
place, much safer and simpler).
Convention was not to but after discussion on 918941483f we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.
This problem existed in 2.79 as well. The rigid body setting is related
to the scene the object was created.
We now clear all the rigid body properties of the appended objects to
prevent them from lingering in this state where they have settings yet
cannot be used in the simulation.

More or less same code was being executed twice during ID copying.
Makes no sense to add yet another switch-by-ID-type to handle
specificaly runtime data during ID copying, we already have
BKE_xxx_copy_data() functions for that.
This is a slightly more risky commit, as it is very difficult to fathom
all that may happen when localazing IDs. Would not expect any issue
though.
Note that a big TODO remain to refactor fully that ID localization
process (for 'shading IDs'), it's still doing pretty much same thing as
regular out-of-main copies, but the infamous ntree topic makes it
delicate to handle...
Those two first sets of flags should represent some common use cases.
The goal here is to reduce verbosity of calls to BKE_id_copy_ex, and
help make it more obvious the 'common behaviours' of ID copying across
codebase.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
Kind of funny to see that this has been missing presumably since the
first version of library linking in Blender, and only gets noticed now.
Then again, that was not really a critical issue, iirc write code
ensures all libraries directly used get properly written, even if flags
are incorrect.
This is a second attempt to get the crash fixed. The original fix
worked, but it was reverted by d3e0d7f082.
Now the logic goes as:
- All pointers which we can not have shared (the ones which are
owned by the runtime) are cleared.
- The rest of runtime stays untouched.
This seems to be enough to keep particles happy.
There were at least three copies of those:
- OB_RECALC* family of flags, which are rudiment of an old
dependency graph system.
- PSYS_RECALC* which were used by old dependency graph system
as a separate set since the graph itself did not handle
particle systems.
- DEG_TAG_* which was used to tag IDs.
Now there is a single set, which defines what can be tagged
and queried for an update. It also has some aggregate flags
to make queries simpler.
Lets once and for all solve the madness of those flags, stick
to a single set, which will not overlap with anything or require
any extra conversion.
Technically, shouldn't be measurable user difference, but some
of the agregate flags for few dependency graph components did
change.
Fixes T58632: Particle don't update rotation settings
All localized datablocks are not supposed to have animation
data associated with them.
There was an easy way to reproduce assert failure: toggle
animation decorator for Viewport Display -> Color.
We already had a BKE_main.h header, no reason not to put there
Main-specific functions, BKE_library has already more than enough to
handle with IDs and library management!
NLA strips are users of their action, so we need to pass along ID
management flags.
This commit also cleans up a bit things by passing along ID_CREATE/COPY
flags instead of dummy booleans...
We want to undo the initial usercount from low-level ID duplication, not
to erase all possible extra processing (like e.g. setting Fake User...).
Fixes part of mess in brush usercount.
Also reshuffle a bit that whole code, did some renaming,
`BKE_id_to_unique_string_key()` is now using same base code (instead of
using whole library filepath...), etc.
