Unicode and fetch class

20 years ago by Marcus Boerger — view source — reply

Hello internals,

Andrei asked me whether we could do something about the double
lowercasing when calling zend_is_callable_check_func(). The attached
patch adds the new fetch flag ZEND_FETCH_CLASS_NO_NORMALIZE which
prevent lowercasing. Also zend_u_lookup_class_ex() got a new parameter
which allows to specify whether the function needs to lowercase or
not. I am quite sure Andrei needs to touch it a bit further but i
think we should discuss this step first.

Best regards,
Marcus

I fixed some bugs and reworked the patch. Please look it over, as I
intend to commit it in the next couple of days.

The next step would be fixing zend_u_str_case_fold() to do only case
folding and having all normalization go through
zend_normalize_identifier().

Of course it would help if I attached the patch..

Hello Andrei,

looks pretty fine to me, after your treatment, go ahead commit - Andi, Zeev?
