Hi,
FOA, I'm glad to say that there is no manual ref counting in WK2 EFL classes any more :)
This however also gives us another enhancement opportunity which I'd like to discuss now.
As all the ref-counting EWK classes are inherited from WTF::RefCounted
it is possible now to have generic REF/UNREF functions in the public API instead of
having separate pair of such functions for every object.
To say in more details we could introduce
struct Ewk_Ref_Counted Ewk_Ref_Counted;
and following generic functions:
EAPI Ewk_Ref_Counted* ewk_ref(Ewk_Ref_Counted*);
EAPI ewk_unref(Ewk_Ref_Counted*);
then Ewk_Back_Forward_List_Item for instance can be declared as
typedef Ewk_Ref_Counted Ewk_Back_Forward_List_Item;
so that it's clear that Ewk_Back_Forward_List_Item is ref-countable.
Would like to hear your opinion about this proposal.
BR,
Mikhail

Hi all,
The idea is that EWK internal structures (those which use ref counting) can be inherited from WTF::RefCounted class,
It gives following benefits:
1) Ref counting code is encapsulated and not copy/pasted between EWK structures.
2) It is possible to use internally RefPtr and PassRefPtr smart pointers which also saves a lot of lines of code
Here you can see an example http://trac.webkit.org/changeset/131298 of the described approach applied.
There is also a meta bug https://bugs.webkit.org/show_bug.cgi?id=99321 for gradual refactoring of all of the EWK classes.
If someone is volunteering to modify a certain EWK class accordingly to the described approach please
put your bug as a dependency for the meta bug.
BR,
Mikhail
