Summary:
Eolian adds a per-class BETA guard (like EFL_UI_WIN_BETA) to any method tagged
as @beta. This means that any app (and the EFL code) wanting to use BETA features
has to enable them class by class, which is cumbersome.
This commit replaces the individual guards with the global EFL_BETA_API_SUPPORT
guard, so apps only need to define one symbol to access BETA features.
Any usage of the per-class guards has been removed from the EFL code and examples.
When building EFL the global guard is defined by configure, so all EFL methods
already have access to BETA API.
Efl_Core.h and Efl_Ui.h no longer define EFL_BETA_API_SUPPORT. Apps wanting to
use BETA API have to define this symbol before including any EFL header
(It has been added to the examples requiring it).
Test Plan:
make && make check && make examples still work, but there's a lot less #defines
in the code

Gesture manager doesn't care about focus manager events, animation events,
and various other things it's currently hooking.
We can save a lot of pointer indirection nonsense by only paying attention
to events it can actually do something with.

it does not really matter if a obj is NULL or not when deleting a callback.
The result might be NULL anyways when the callback is not found.
Additionally, this is very verbose, and leads to the fact that most of
the time normal calls to evas_object_event_callback_del* should be if
(!obj) evas_object_event_callback_del* which is annoying and wastefull.

Summary:
To take screenshots, Enlightenment makes a new snapshot object, performs
a manual render, and uses the snapshot results.
Turns out if this happens while an async render is in progress, the
async render's completion triggers a render post callback on the snapshot
object even though it's never been involved in a render.
We need to defer new render post callbacks until any currently running
render completes, then add them during that render's post.

so the MAIN loop is actually an efl.app object. which inherits from
efl.loop. the idea is that other loops in threads will not be efl.app
objects. thread on the creator side return an efl.thread object.
inside the thread, like the mainloop, there is now an efl.appthread
object that is for all non-main-loop threads.
every thread (main loop or child) when it spawns a thread is the
parent. there are i/o pipes from parnet to child and back. so parents
are generally expected to, if they want to talk to child thread, so
use the efl.io interfaces on efl.thread, and the main loop's elf.app
class allows you to talk to stdio back to the parent process like the
efl.appthread does the same using the efl.io interfaces to talk to its
parent app or appthread. it's symmetrical

So, this is maybe not the best fix. The question is should we be able to
get efl_data_scope_safe_get return the object private data, when we are
currently executing the object EFL_EVENT_DEL callbacks. Right now we don't
and this lead to bug where we wouldn't have been able to destroy a callback
and get that callback triggered later on destroyed data (I had a crash in
terminology). I have switched back to the not _safe_ version which doesn't
enforce this, but that might not be the only place that need a fix.
this fixes a bit wraparound in the shift as the 1 is an int (32bit)
type that then gets shifted .. then after that cast to 64bit.

Eina_Clist can actually change the pointer in the cell next bypassing
the CoW infrastructure leading to trouble. Considering the case here,
using the optimization of Eina_Clist is not necessary and if performance
issue arise, can be fixed by using a dichotomic search when removing
data. I don't think it is necessary to add this complexity without
a real life case.
This reverts commit f69686ba40.
this causes major crashes in e every time you move and resize a
window. i cant even debug it properly because i cant move or resize
windows to get terminals up to debug it... this is bad... so until a
fix is found better to go back to working...
adding an "event rect" is a common use case for rectangles, but I needed
a smarter event rect so I sent one off to school and it came back like this.
an event_grabber is a smart object which functions like a normal event rect
which has color(0,0,0,0), but with an important difference: it can have smart
members. event propagation works differently for an event_grabber:
normal:
event -> layer -> smart(obj1,obj2,obj3) ->(?) other objects
in this case, obj1,obj2,obj3 are all "inside" the smart object and their stacking
will always be considered as being inside the smart object. rendering is also
tied to the smart object in this case, as is clipping.
an event which reaches a smart object will be sent to the objects inside,
and then may continue through the smart object if there are no objects which
block repeating.
event_grabber:
event -> layer -> event_grabber -> obj1,obj2,obj3 -> STOP
in this case, obj1,obj2,obj3 are unmodified after being added to the event_grabber
and can be stacked, rendered, and clipped completely independently of the
event_grabber.
the event_grabber is considered an "event_parent" for this case. member objects
are not "inside" the event_grabber, and they are unable to receive events on
their own. instead, the event_grabber, which must be stacked above all its
members, receives events and propagates them top->down through its member objects.
if none of the member objects block the repeat of an event then the event will
still be blocked from further propagation past the event_grabber.
object lifetimes are independent of the event_grabber; deleting the event_grabber
has no effect on its members.
@feature
Since ecore now uses efl events to feed input events to the
canvas, anyone can now listen to any event on the evas. But
when using the legacy API the event info needs to be the legacy
struct, and not the eo event info otherwise crashes will happen.
While this is a new use of events, I consider it valid and it's
better to fix it rather than disallowing it. Fixed by wrapping
evas events the same way evas object events were handled.
Fixes T5266
The previous patch (b184874fa5) was preventing
post-event callbacks from triggering any form of input event,
including side-effects due to mouse,in. In fact by tracking
which exact events we want to post-process we can support
proper recursion. This fixes crashes in Bryce.
I'm not changing the documentation as this is still a dubious
code design.
Fixes T3144
Fixes T5157
See T3144 that I marked as Wontfix.
Bryce in E manually feeds events from a post-event callback
resulting in Evas going insane and leading to frequent crashes.
The ideal solution (for E) would be to ensure that everything works
smoothly, the input event data is valid up until the post-event cb
is called, etc... Unfortunately, with recursive events the exact
order of operations may be messed up: the post-event
I don't want to add yet more complexity to Evas events here (it's
already spaghetti all over the place) so I'm simply blocking any
new event feed when running the post-event callback list.
It's not possible to just freeze the events (I tried, it failed).
**********************
Some more explanation:
post-event callbacks are used to implement reverse-order logic
where the on-hold flag of an input event may be set by an event
listener that does not come first.
Here's a situation to illustrate: scroller A inside scroller B.
As events are propagated from children to parents (assuming the
propagate flag is set), we'd assume the events to go first to A
and then to B, which means a mouse wheel event would make the
inner-most scroller (A) scroll, and the outer-most scroller (B)
wouldn't budge.
But as things are designed, A and B are not simple evas objects,
and the actual event-catching object is a top-most transparent
rectangle (top-most in Z stack order). Since A is inside B, B's
rectangle BR is over A's rectangle AR, thus catches the wheel
event first. But in terms of UX we still want A to scroll, not B.
The solution then is to reverse the event processing order and
post-event callbacks are the way to do that. This comes with the
consequence that the event_info needs to remain valid until the
post-event is called, and stay the same (so that the on-hold flag
set by A can be read by B).
Recursive events (by explicit feed or modifying the canvas so
that mouse,in or mouse,out are triggered) mess with this logic,
and trigger the post-events too early (event is not fully
processed) or too late (event_info is not valid anymore... and
crash!).
Thanks @raster for explaining the goal of post-event callbacks!
A use of the post event callback in Bryce triggered a double free
as an event was being processed but not yet removed from its list,
leading to an invalid state of the Eina_List.
Also remove obj from struct as it is unused.
Fixes T5157
In case of a mapped object (eg. when applying a map to a window
in wayland compositor), the canvas and output coordinates are
not meant to be the same.
In EO land, applications should instead use the common interface
Efl.Input.Interface.pointer_xy.get (on the canvas).
@fix
before changing MAGIC_CHECK to eo_isa passing NULL to a function would
result in nothing, now it gives a error message. This restores the old
behaviour.
After my many input events changes, a same object callback
could be called multiple times in a row because both mouse
and multi events were sent. As such, the multi event had no
direct effect (no callback called) but it reset the object's
last event type. This allowed the mouse event callbacks to be
called again.
Note that I haven't tested multi touch yet :(
Very good catch by @bu5hm4n!
Fixes T4462
Fixes T4467
Efl.Object.event_callback_call no longer calls legacy smart callbacks;
calling only event callbacks registered with the given event description
pointer.
Create the method Efl.Object.event_callback_legacy_call to inherit the old
behavior from Efl.Object.event_callback_call, calling both Efl.Object events
and legacy smart callbacks.
Update all other files accordingly in order to still supply legacy
callbacks while they are necessary.
This removes useless magic checks (only check whether the
arg is not null) that were not even present in every function.
The cost should be similar or lower than an eo function call.
This removes:
Efl.Event interface
And renames:
Efl.Event.Input -> Efl.Input.Event
Efl.Event -> Efl.Input.Event (merged)
Efl.Event.Pointer -> Efl.Input.Pointer
Efl.Event.Key -> Efl.Input.Key
Efl.Event.Hold -> Efl.Input.Hold
This also moves some interfaces from efl/ to evas/ where they
belong better.
This allows renaming Eo_Event to Efl_Event.
