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.
ref T7681
Differential Revision: https://phab.enlightenment.org/D7882
This changes a lot of things all across the EFL. Previously,
methods tagged @const had both their external prototype and
internal impl generated with const on object, while property
getters only had const on the external API. This is now changed
and it all has const everywhere.
Ref T6859.
Because of a typo in generator source (and overlooked error in
tests) we were previously generating incorrect code for setters
with the @auto qualifier. This was brought up in D5306 and is
now fixed.
If you define either the macro MY_CLASS_EXTRA_OPS for normal
methods/properties or MY_CLASS_EXTRA_CLASS_OPS for class methods
or properties, which contains a comma-delimited list of ops defs
(i.e. EFL_OBJECT_OP_FUNC(...), ...) right before including the
generated my_class.eo.c file, the definitions from these will
be included in the actual class. This can be used to override
certain things in a class internally without exposing it to
Eolian, or for testing/debugging.
As there is no need to have separate is_auto, is_empty and
is_pure_virtual for functions and implements (each function has
its own base implement by default) I removed the function ones.
Instead, I added a way to retrieve a function's base implement
so that you can instead do the checks on the implement even when
you only have the function.
I also moved base implement build directly into the parser instead
of the database filler. That allows for significant cleanup. I
also removed distinction of implement pointers in Eolian_Function
for get and set as implements now always contain an entire thing
so the pointer was always the same anyway.
Things should still behave more or less the same, but ordering
of generated functions has changed because ordering of implements
has changed.
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.
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.

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.
Local and base class functions are supported.
When @empty is provided, dummy functions (initializing the parameters with default
values if needed) are generated.
When @auto is provided on properties, access to internal data variables is done. On
set, it will assign parameters values to private data members. On get,
parameters are set with private data members values.
See the supplied tests as examples.
