| PHP 8.5 INTERNALS UPGRADE NOTES |
|
|
| 1. Internal API changes |
|
|
| 2. Build system changes |
|
|
| 3. Module changes |
|
|
| 4. OpCode changes |
|
|
| 5. SAPI changes |
|
|
| ======================== |
| 1. Internal API changes |
| ======================== |
|
|
| - Core |
| . PG(arg_separator).input and PG(arg_separator).output are now `zend_string*` |
| instead of `char*`. |
|
|
| - Zend |
| . Added zend_safe_assign_to_variable_noref() function to safely assign |
| a value to a non-reference zval. |
| . Added zval_ptr_safe_dtor() to safely destroy a zval when a destructor |
| could interfere. |
| . zend_get_callable_name() now returns the name of the underlying function |
| for fake closures. |
| . Added smart_string_append_printf() matching smart_str_append_printf() for |
| char* instead of zend_string*-based smart strings. |
| . Added php_build_provider() to retrieve the value of PHP_BUILD_PROVIDER at |
| runtime. |
| . Removed the cache_slot argument of zend_check_user_type_slow() because |
| now it only relies on the CE cache. |
| . Added ZEND_NONSTRING attribute macro for character arrays that do not |
| represent strings. This allows to silence the GCC 15.x |
| `-Wunterminated-string-initialization` warning. |
| . Added the zend_update_exception_properties() function for instantiating |
| Exception child classes. It updates the $message, $code, and $previous |
| properties. |
|
|
| ======================== |
| 2. Build system changes |
| ======================== |
|
|
| - Windows build system changes |
| . SAPI() and ADD_SOURCES() now suport the optional `duplicate_sources` |
| parameter. If truthy, no rules to build the object files are generated. |
| This allows to build additional variants of SAPIs (e.g. a DLL and EXE) |
| without duplicate build rules. It is up to the SAPI maintainers to ensure |
| that appropriate build rules are created. |
|
|
| - Linux build system changes |
| . libdir is properly set when --libdir (ex: /usr/lib64) and --with-libdir (ex lib64) |
| configure options are used to ${libdir}/php (ex: /usr/lib64/php) |
|
|
| ======================== |
| 3. Module changes |
| ======================== |
|
|
| - ext/gd |
| . The gdImageScale*() and gdImageRotate*() helpers are now internal in the |
| bundled libgd, like they have been in external libgd as of gd-2.1.1. |
|
|
| - ext/json |
| . php_json_encode_serializable_object() now assumes `EG(active)`, |
| if not a bailout is caused. Therefore a minor BC break exists if the |
| `PHP_JSON_PARTIAL_OUTPUT_ON_ERROR` option is in use. |
| However, this situation is highly unlikely. |
|
|
| - ext/libxml |
| . The refcount APIs now return an `unsigned int` instead of an `int`. |
| . Removed php_libxml_xmlCheckUTF8(). Use xmlCheckUTF8() from libxml instead. |
|
|
| - ext/pdo |
| . Added `php_pdo_stmt_valid_db_obj_handle()` to check if the database object |
| is still valid. This is useful when a GC cycle is collected and the |
| database object can be destroyed prior to destroying the statement. |
|
|
| - ext/standard |
| . Added php_url_decode_ex() and php_raw_url_decode_ex() that unlike their |
| non-ex counterparts do not work in-place. |
| . The php_std_date() function has been removed. Use php_format_date() with |
| the "D, d M Y H:i:s \\G\\M\\T" format instead. |
| . Added php_url_encode_to_smart_str() to encode a URL to a smart_str buffer. |
