With this new API one can block or unblock keyboard, mouse and
focus events that was originated from a seat. This is useful to
create applications that wants to establish some kind of seat segregation.
This patch introduces the possibility to set the pointer mode and
query other properties like current position per pointer device.
The old API will still works, however it will only act on the default seat.
evas_object_clip_recalc is big. it's fat. it shouldnt be inline. so
make it a real function. being inline just hurts performance by making
our code bigger, hurting l1 instruction prefetch and cache
performance. this function isn't small. it's huge and should not be
inline basically because of that reason.
also throw in some likely/unlikely hints etc.

After a few patches trying to fix clipping of frame or
non-frame objects the icon finally ended up invisible. Even
if the elm_icon was marked as is_frame, its internal evas
object image would not have the flag set, thus it would be
clipped out.
Solution: Propagate the is_frame flag to all smart children,
not only when setting it but also when adding new members.
A hack with the API indicates that the frame edje is a very
special object that does not propagate the flag.

Using the multi-seat support, Evas is able to handle multiple focused objects.
This implementation allows one focused object per seat.
This patch introduces new APIs and events to handle this new scenario,
while keeping compatible with the old focus APIs.
See T4749, 11b7cf6b72 introduced an issue and
e1e28ce320 fixed it but caused a massive
performance impact.
This should fix that. Thanks @zmike for the first patch.

so i have been doing some profiling on my rpi3 ... and it seems
memcmp() is like the number one top used function - especially running
e in wayland compositor mode. it uses accoring to perf top about 9-15%
of samples (samples are not adding up to 100%). no - i cant seem to
get a call graph because all that happens is the whole kernel locks up
solid if i try, so i can only get the leaf node call stats. what
function was currently active at the sample time. memcmp is the
biggest by far. 2-3 times anything else.

yeah. it's perf. it's sampling so not 100% accurate, but close to
"good enough" for the bigger stuff. so interestingly memcmp() is
actually in a special library/module (libarmmem.so) and is a REAL
function call. so doing memcmp's for small bits of memory ESPECIALLY
when we know their size in advance is not great. i am not sure our own
use of memcmp() is the actual culprit because even with this patch
memcmp still is right up there. we use it for stringshare which is
harder to remove as stringshare has variable sized memory blobs to
compare.
but the point remains - memcmp() is an ACTUAL function call. even on
x86 (i checked the assembly). and replacing it with a static inline
custom comparer is better. in fact i did that and benchmarked it as a
sample case for eina_tiler which has 4 ints (16 bytes) to compare
every time. i also compiled to assembly on x86 to inspect and make sure
things made sense.
the text color compare was just comparing 4 bytes as a color (an int
worth) which was silly to use memcmp on as it could just cast to an
int and do a == b. the map was a little more evil as it was 2 ptrs
plus 2 bitfields, but the way bitfields work means i can assume the
last byte is both bitfields combined. i can be a little more evil for
the rect tests as 4 ints compared is the same as comparing 2 long
longs (64bit types). yes. don't get pedantic. all platforms efl works
on work this way and this is a base assumption in efl and it's true
everywhere worth talking about.
yes - i tried __int128 too. it was not faster on x86 anyway and can't
compile on armv7. in my speed tests on x86-64, comparing 2 rects by
casting to a struct of 2 long long's and comparing just those is 70%
faster than comapring 4 ints. and the 2 long longs is 360% faster than
a memcmp. on arm (my rpi3) the long long is 12% faster than the 4 ints,
and it is 226% faster than a memcmp().
it'd be best if we didnt even have to compare at all, but with these
algorithms we do, so doing it faster is better.
we probably should nuke all the memcmp's we have that are not of large
bits of memory or variable sized bits of memory.
i set breakpoints for memcmp and found at least a chunk in efl. but
also it seems the vc4 driver was also doing it too. i have no idea how
much memory it was doing this to and it may ultimately be the biggest
culprit here, BUT we may as well reduce our overhead since i've found
this anyway. less "false positives" when hunting problems.
why am i doing this? i'm setting framerate hiccups. eg like we drop 3,
5 or 10 frames, then drop another bunch, then go back to smooth, then
this hiccup again. finding out WHAT is causing that hiccup is hard. i
can only SEE the hiccups on my rpi3 - not on x86. i am not so sure
it's cpufreq bouncing about as i've locked cpu to 600mhz and it still
happens. it's something else. maybe something we are polling? maybe
it's something in our drm/kms backend? maybe its in the vc4 drivers or
kernel parts? i have no idea. trying to hunt this is hard, but this is
important as this is something that possibly is affecting everyone but
other hw is fast enough to hide it...
in the meantime find and optimize what i find along the way.
@optimize
This is an override of efl_gfx_size_set. Same as before, the
order of operations matter so it is possible that a corner
case will break. In particular, legacy code was:
- intercept
- smart resize (do stuff), super, super, super
- evas object resize
The new code is more like:
- intercept
- super, super, super, evas object resize
- do stuff
But unfortunately this broke elm_widget (read: all widgets) as
the internal resize was done before the object resize. So,
inside the resize event cb, the resize_obj size would not match
the smart object size. >_<
This is an override of efl_gfx_position_set.
As for the other patches, I hope I didn't break anything.
A problem likely to happen is that the super call was inserted
too early or too late in the call flow. For instance:
_myclass_position_set(obj, x, y) {
position_set(super(obj), x, y);
position_get(obj, &prevx, &prevy);
do_something_with_delta_xy();
}
The above code flow is obvisouly wrong, but may have crept in this
patch (such a bug sneaked in inside smart object, breaking
everything at first).
These should be just overrides of Efl.Gfx.visible.set. Many
widgets were handling smart show() and hide() manually, which
means this patch is quite large.
Hopefully this doesn't break anything, obviously. But here are
some widgets known to be problematic, as the old code flow was
really strange (sometimes not calling the efl_super function):
- window
- notify
Widgets should simply override efl_gfx_color_set and call
super all the way up to evas object.
Legacy compatibility with call interceptors and early call
abortion (eg. delete_me or obj->layer == NULL) are implemented
with an internal call. See the previous commit introducing the
API.
This is a poor man's solution to get rid of group functions such
as clip_set, clip_unset, color_set, etc... See the following
commits.
This API needs to be EAPI for elementary but shouldn't be used
outside EFL. This is required purely for legacy compatibility.
Here's the call flow, inside show(obj):
1. if (intercept_show(obj)) return;
2. show(super(obj));
3. do other stuff
Due to the way the clip geometry calculation changed
(see 25d77bc1d2) to be
based on the bounding box rather than the raw geometry
of smart objects, the internal function
evas_object_is_in_output_rect() now returns true if the
rectangle intersects with that bounding box, even if
it's outside the raw geometry.
This breaks the drop area in E's pager, as it relies on
evas_objects_at_xy_get() to find which objects are at
this point. What I saw on my desktop was that only the
lower 10 or 20 pixels were droppable in the pager,
as maximized windows would have shadows covering the
upper 20 pixels or so.
Arguably objects_at_xy_get could also return all objects
at (x,y) including smart objects that extend beyong their
geometry. This can be added as a flag in the EO API, but
not in the legacy API.
This removes some useless code in various places, where the
switch from eo_do() to standard function call was not properly
refactored.
This changes:
type ret = 0;
ret = my_eo_function();
return ret;
To:
return my_eo_function();
so smart object bounding box wasnt updated properly in several other
cases. fix those other cases too by dirtying bounding box region.

@fix
Evas.Common_Interface not only had a bad name, it also
wasn't in line with how we can get a loop object, for
instance.
Use eo_provider_find in each implementing class.
Note: Only two modes are supported (blend and copy).
The Efl.Gfx and Evas enums were different. All other values
were not supported. For legacy compatibility (since GL engine
actually implements some kind of support for all operations),
render_op_set() should still work fine, even though it's not
recommended, and won't work anymore with EO API.
This is a horrible API used for internal optimizations. Which
may or may not be partly broken anyway.
We can do better, in the future. Let's not expose this kind
of API.
Now called "hint_min", not sure if it's the proper name for it.
At first I wanted to reuse the request size hint instead of
adding a new hint, but doing that would break Terminology
or any app that already used size_hint_request.
One problem with hint_request is that the legacy function
already exists but its support is practically not implemented.
@feature
Still not sure about which keyword is the best to use here,
but anyway, it's a protected function so users should realize
it's probably not what they want.
This includes:
- align
- min (now content_min)
- request
- max
- padding (now margin)
- weight
This does NOT include:
- display mode (compress, expand... a hint used by naviframe only).
Problem:
- edje aspect ratio is defined by 1 enum and 2 double (min, max)
- window aspect ratio is defined by only 1 double
- evas object aspect ratio is defined by 1 enum and 2 ints (w, h)
Which one is the best interface? Are min/max a better option?
Also, not sure how to call the enum...
So, I was stupid. I was relying on legacy callbacks to
trigger eo events, which means that only when a legacy
callback was registered would my new eo events be triggered.
Instead, I can pass the eo event desc & info whenever
calling evas_object_event_callback_call().
This reverts commit 546ff7bbba.
It seems that eo_del() is useful and removing it was creating bugs.
The issue is that the way we defined parents in eo, both the parent and
the programmer share a reference to the object. When we eo_unref() that
reference as the programmer, eo has no way to know it's this specific
reference we are freeing, and not a general one, so in some
circumstances, for example:
eo_ref(child);
eo_unref(child); // trying to delete here
eo_unref(container); // container is deleted here
eo_unref(child); // child already has 0 refs before this point.
We would have an issue with references and objects being freed too soon
and in general, issue with the references.
Having eo_del() solves that, because this one explicitly unparents if
there is a parent, meaning the reference ownership is explicitly taken
by the programmer.
eo_del() is essentially a convenience function around "check if has
parent, and if so unparent, otherwise, unref". Which should be used when
you want to delete an object although it has a parent, and is equivalent
to eo_unref() when it doesn't have one.
