Hi guys,
I still don't have time to play/help with Eina, but from what I saw so
far, I'd like to propose some ideas and request some features:
- make data types thread safe. I know evas and other libraries are
not thread safe, but not being able to create lists, arrays and hashes
on different threads is too much limited! I'm not talking about append
to the same list from different threads, but creating nodes for
different lists on different threads. Today this will fail because of
mempool and other cache.
- provide iterator pattern as a different, complementary system. I'm
using this with Guarana and have iterator for my own list and also
Evas_List. What I have is something as simple as:
eina_iterator_t *eina_XXXX_iterator_get(XXXX_t *object);
int eina_iterator_next(eina_iterator_t *itr, void **data);
void eina_iterator_del(eina_iterator_t *itr);
typedef struct { int (*next)(eina_iterator_t *itr, void
**data); void (*free)(eina_iterator_t *itr) } eina_iterator_t;
users can "extend" from eina_iterator_t and append required
fields, like current list node. This simplifies iteration and
abstracts if you want to use array, lists and even Python/Perl/JS list
objects.
- provide accessor (? don't know the real name) pattern, similar to
iterator, this one will access based on index. This one make code
really simple and if you implement it right, for Evas_List you can
have very quick access if you remember last accessed node and search
from head, tail or current position. I also have this code and can
contribute with Evas_List example.
