eina_tls_get is really slow, having a fast path for the main loop does really
help us right now. It is also unlikely that slowing down a little bit the use
of eo in thread is going to have any impact on application speed any time soon.
I win a +10% on expedite benchmark compared to without.

This enables checking if an object is being created, or has already been
finalized. This is useful in functions that you want to allow
only during the creation phase (i.e inside the eo_add()).
Comp objects are rare, and since we allow using classes as interfaces,
we end up allocating a lot of memory for something we don't even use.
That's why it was a linked list in the first place, and that's why it
should remain a list.
This is almost a complete revert. I reverted the code itself, and the
intent (use of array instead of list), but not the tests, or the new
return value added to comp_detach, which is useful.
This reverts commit ef09ef7489.
This function lets you hook at the end of eo_add and override it for a
class. This is essentially the first step towards killing custom
constructors. Instead of having a custom constructor, you should just
do:
eo_add(CLASS, parent, a_set(3), b_set("eou"));
eo_constructor is called at the beginning for pre-init things.
eo_finalize is called at the end, for actually finalizing and doing
things. This cleans up the API and possibly saves a lot of things that
would have been stupid and slow in the past, like loading an elm widget
with an existing theme, and then changing the theme.
** This breaks Eo ABI, please recompile elementary and everything else that
creates eo objects.

this fixes and eo2 problem where when callstack grows (or shrinks)
and realloc nas to relocate memory, the frame ptrs like fptr become
invalid and all sorts of hell ensues.
this uses mmap so blowing the stack will segv, not scribble over
memory, also its separated from malloc heap, and now big enough to not
need to size ... ever (1024 entries).
It's now completely valid to do:
a = eo_do(obj, a_get());
or:
b = eo_do(obj, a_set(1), b_get());
Also, the default return value for eo2 functions is now also returned
when the object is invalid, not just when the object does not match
class.
It's a small refactor that fixed both issues at once.
@feature
@fix
create/destroy tls key (_eo2_call_stack_key) at eo_init()/eo_shutdown().
use _eo2_call_stack_get() to allocate the stack when required.
register _eo2_call_stack_free() as eina_tls_cb_new() delete callback.
eo_class_new() returns NULL on error in _eo2_class_funcs_set().
it covers: NULL API func, API redefined, dich func override,
overriding non-existing fct.
as op descs are sorted, we can't output fct indexes in error msgs, but
as they are sorted using api_fct as key, we can detect multiple usage of
the same api_fct which leads to an unpredictable call to whatever is
returned by _eo2_api_op_id_get()->_eo2_api_desc_get().
it is still possible to instanciate an object of a not well defined class.
a mixin class must not inherit
- _eo2_api_desc_get()
accept NULL klass param
EO_CLASS_TYPE_REGULAR_NO_INSTANT is an acceptable extension class type for
- _eo2_class_funcs_set() do not shout if parent is NULL
there is no more difference in class or regular functions prototypes and definitions
- eo2_api_op_id_get() uses _eo_is_a_class() at runtime
- add 'void *class_data EINA_UNUSED' parameter to eo2_base class functions
- Eo2_Op_Call_Data.klass is kept only for eo2_hook_call_pre end eo2_hook_call_post,
but could be removed easily
in the EPAI, don't show that Eo* could be IDs.
in the implementation, use klass_id and obj_id
if you know or want it to be a class or an object,
use eo_id in general cases.
We want to have normal functions as non-default constructors, not va_arg
ones. What we should do is split the object creation to two parts again.
The creation, the constructing (changes using the macro) and the
verification/end part that checks the constructor has been called.
This reverts commit 2ff2ce1894f173b306a896bda595e1a7768c074d.
to protect us against bad use of break, goto, return ... in eo2_do,
we use __attribute__((cleanup(eo2_do_end))) to ensure that eo2_do_end()
is called whatever.
at class elaboration, sort the op descriptions using the function pointer.
when calling a function, do a dichotomic search in the
class op descriptions to find the corresponding OP_ID,
then keep it in a static variable.
All classes are allowed, because all classes can be used as interfaces in
order to override behaviour. This is especially needed for mixins and broke
the eo2 tests.
Was fien on the normal path but missing on the error path. Also remove
the spurious break after the return. Would never be reached. Looks like
a copy and paste bug to me.

This patch sets the one before most significant bit on for classes. This
means that class ids are now very big, compared to the old ids which
were growing small integers (1, 2, 3...).
This makes accidental passing of integers (corrupted obj pointers) less
common.
@feature
as we don't support multiple composites of the same class,
and know at class elaboration how many composites we should have,
we can create the composites array and pack it at the end of the object.
@fix
mixins data offsets are stored in Eo_Extension_Data_Offset[],
if the constructed class is a mixin, do not reserve space for its
private data, the class is in mixins list and will be handled at
Eo_Extension_Data_Offset computation.
see _eo_data_scope_get(...) for private data retrieval
as we don't support multiple composites of the same class,
and know at class elaboration how many composites we should have,
we can create the composites array and pack it at the end of the object.
eo_composite_attach fail if the class of the composite is not
listed in the parent class extensions, or if there is already a
composite of the same class. The later because calls are
forwarded to the first responding composite, see _eo_op_internal().
This reverts commit ee1b0833ed
I did it manually because the code changed too much.
We actually want this type, it makes things more clear and easier to
understand.
