Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

As in the previous commit explained, we want to get rid of class
functions in eo, and make them just c functions right away.
This commit removes the class parameter from the eo_class_function_set
call, and adjusts the tests to not depend on class functions anymore.
Class functions are now not tested anymore, tests that used them as a
way to test *things* are adjusted to test them now with object
functions, tests that just tested the working of class functions are
dropped.
This fixes T7675.

The next commit will bring support for something like reflection. This
commit prepares the whole tree for getting another argument in
efl_class_functions_set.

mro only contains special interfaces, not in general all, in order to
have a working function, while NOT having a bad performance. In order to
achive that we just copy the code that is done on efl_isa for a object.

This build was never complete and also was not maintained probebly.
It is also dropped in favour of meson which is cool, merged, works & is fast.
Differential Revision: https://phab.enlightenment.org/D7010
a new shiny buildtool that currently completes in the total of ~ 4 min..
1 min. conf time
2:30 min. build time
Where autotools takes:
1:50 min. conf time
3:40 min. build time.
meson was taken because it went quite good for enlightenment, and is a traction gaining system that is also used by other mayor projects. Additionally, the DSL that is defined my meson makes the configuration of the builds a lot easier to read.
Further informations can be gathered from the README.meson
Right now, bindings & windows support are missing.
It is highly recommented to use meson 0.48 due to optimizations in meson
that reduced the time the meson call would need.

This fixes an issue where efl_isa() wouldn't work for extensions or
ancestors of extensions of a class.
Example:
Class A implements interface F2
F2 inherits from interface F1
obj is of class A
Before this patch efl_isa(obj, F1) would return false, now it returns
true as expected.
This is just one example, there is a whole array of variations to this
issue that are now fixed.
Thanks to Gustavo for reminding me of this.
@fix
This change lets us remove a field from the structure that leads to
around 20KiB more of saving in private dirty pages in elementary.
This also looks a bit better and feels a bit cleaner.
Breaks API and ABI.
Before this commit, function overrides were explicit. That is, you'd
have to explicitly state you were overriding a function instead of
creating a new one. This made the code a tad more complex, and was also
a bit more annoying to use. This commit removes this extra piece of
information.
This means we now store much less information per function, that will
let us further optimise out structures in the future.
This was never used and there is no plan to ever use it. I'm going to
soon add a different mechanism with which it will be possible to provide
them again to Eo if ever needed without breaking ABI. Though it's
unlikely it will ever be.
Modify the way hooks are defined and used by promise generation in
Eolian in the Eo API.
Instead of passing macro names as parameters to EO_FUNC_BODY macros,
just re-define the actual hooks when it is needed.
Add two parameters for macros that generate API functions in Eo so
that the generation can be customized with macros used by Eolian.

I just ran my script (email to follow) to migrate all of the EFL
automatically. This commit is *only* the automatic conversion, so it can
be easily reverted and re-run.
This hasn't been used for a while. Since we are going to break Eo a bit anyway
it's a good opportunity to drop this.
This may cause a slight performance issues with legacy events, such as
smart callbacks. This shouldn't really be a problem as we've migrated away from
them. If it does, we need to migrate the remaining parts. Only relevant
for callbacks that are added before the classes are created, which
shouldn't be possible except for smart, only for old evas callbacks.
This reverts commit 1714fe93f4.
We actually want this type, it makes things clearer.
