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 a promise object to allows Eolian interface to include promises
as a way to have asynchronous value return and composibility.
The usage is like this in a .eo file:
class Foo {
methods {
bar {
params {
@inout promise: Promise<int>;
}
}
}
}
Which will create the following API interface:
void foo_bar(Eo* obj, Eina_Promise** promise);
and a Eina_Promise_Owner for the implementation, like this:
void _foo_bar(Eo* obj, Private_Data* pdata, Eina_Promise_Owner* promise);

Add two parameters for macros that generate API functions in Eo so
that the generation can be customized with macros used by Eolian.

Reverting this at Felipe's request following my email. There are many
things I strongly object to in this commit. I've touched the surface of
those on the ML (which doesn't work at the moment), though we need to
better discuss it.
The gist:
1. dlsym is a really bad hack that is not even needed.
2. I don't see why eo should even be aware of promises. It's not aware
of list, hash and etc.
3. The eolian changes were done wrong.
This should have been discussed and consulted before done, even if only
because of the amount of hacks it includes and the cross-domain (ecore,
eo and eolian) nature of it.
This reverts commit f9ba80ab33.
Add a promise object that allows Eolian interface to include promises
as a way to have asynchronous value return and composibility.
The usage is like this in a .eo file:
class Foo {
methods {
bar {
params {
promise: Promise<int>;
}
}
}
}
Which will create the following API interface:
void foo_bar(Ecore_Promise** promise);
and the equivalent declaration for implementation.
However, the API function will instantiate the Promise for the
user and the implementer of the class.
This allows generators to silence type errors in validation in order
to reduce duplicate error messages when generating multiple files.
Also adjusted the C generator to only emit type errors when generating
Eo header files.
@feature
Until now it wasn't allowed/possible to init (eo_init) eo after it has
been shut down (eo_shutdown). This commit fixes that, so now that is
fully legal to have as many init/shutdown cycles as you want.
There was a previous workaround for this issue:
e47edc250d.
This should allow more flexibility when using the EFL in loadable
modules and in various other scenarios.
The problem is that the class_get() functions cache the previously
created class for efficiency, but the class is freed if eo is shut down,
so the cached pointer is actually invalid.
The solution to the problem was to maintain a generation count
(incremented every time we shut down eo), and compare that to a locally
saved version in class_get(). If they don't match, recreate the class,
as it has already been freed.

As described by Carsten in his email to edev ML titled:
"[E-devel] eo stability - i think we need to postpone that"
with the switch to Eo2 we significantly increased our usage of RW memory
pages, and thus significantly increased our memory usage when running
multiple applications.
The problem was that during the migration to Eo2 the op id cache and the
op description arrays were merged, causing the op description arrays to
no longer be RO. This patch enables users of Eo (mainly Eolian) to
declare those arrays as const (RO) again, saving that memory.
There might be performance implications with this patch. I had to remove
the op desc array sorting, and I used a hash table for the lookup. I
think the op desc sorting doesn't really affect performance because that
array is seldom accessed and is usually pretty short. The hash table
is not a problem either, because it's behind the scenes, so it can be
changed to a more efficient data structure if the hash table is not good
enough. The hash table itself is also rarely accessed, so it's mostly
about memory.
Please keep an eye for any bugs, performance or excessive memory usage.
I believe this should be better on all fronts.
This commit *BREAKS ABI*.
@fix
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.
It's now generalized to work properly with legacy functions
as well as correctly append suffixes. Thus, it can be easily
used with the documentation generator and in other places.
