PHP 8.4 INTERNALS UPGRADE NOTES
1. Internal API changes
2. Build system changes
3. Module changes
4. OpCode changes
5. SAPI changes
========================
1. Internal API changes
========================
* zend_register_module_ex() now takes an additional int module_type argument.
This function will also assign the module number and type, there is no need
to do this at the call site anymore. Writing the handle should happen after
successful registration.
* ZPP now accepts a F or Z_PARAM_FUNC_NO_TRAMPOLINE_FREE type check.
This is identical to the 'f' or Z_PARAM_FUNC type check, except the FCC is
always initialized because it doesn't free trampolines.
Trampolines MUST be freed using zend_release_fcall_info_cache() or consumed.
Z_PARAM_FUNC_EX2 was added as well with the same arguments as Z_PARAM_FUNC_EX
plus an additional argument free_trampoline.
* The zend_object_iterator_funcs valid member has changed its signature from
int(*)(zend_object_iterator *) to zend_result(*)(zend_object_iterator *) to
be more in line with what callbacks are returning.
* The backwards compatibility headers ext/standard/{php_lcg.h,php_mt_rand.h,
php_rand.h,php_random.h} have been removed. Include ext/random/php_random.h
directly.
========================
2. Build system changes
========================
a. Unix build system changes
- The configure option --with-zlib-dir has been removed.
- Symbol COOKIE_IO_FUNCTIONS_T has been removed (use cookie_io_functions_t).
========================
3. Module changes
========================
a. ext/dom
- dom_read_t and dom_write_t now expect the function to return zend_result
instead of int.
- The macros DOM_NO_ARGS() and DOM_NOT_IMPLEMENTED() have been removed.
b. ext/random
- The macro RAND_RANGE_BADSCALING() has been removed. The implementation
should either be inlined and undefined behavior fixed or it should be
replaced by a non-biased scaler.
- The generate member of a php_random_algo is now expected to return
the new php_random_result struct, replacing the last_generated_size
member of the php_random_status struct and the generate_size member of
the php_random_algo struct.
c. ext/xsl
- The function php_xsl_create_object() was removed as it was not used
nor exported.
d. ext/libxml
- Added php_libxml_pretend_ctx_error_ex() to emit errors as if they had come
from libxml.
- Removed the "properties" HashTable field from php_libxml_node_object.
e. ext/date
- Added the php_format_date_ex() API to format instances of php_date_obj.
- Added the php_date_initialize_from_ts_long() and
php_date_initialize_from_ts_double() to initialize a php_date_obj with
the given unix timestamp using GMT +00:00.
d. ext/pcre
- php_pcre_match_impl() now no longer has a use_flags argument.
When flags should be ignored, pass 0 to the flags argument.
- php_pcre_match_impl() and pcre_get_compiled_regex_cache_ex() now use
proper boolean argument types instead of integer types.
