# By Adam Harvey (2) and others
# Via Adam Harvey (2) and others
* 'master' of https://git.php.net/repository/php-src:
  Implement variadic function syntax
  Added function opcache_compile_file() to load PHP scripts into cache without execution.
  Fixed issue #135 (segfault in interned strings if initial memory is too low)
  Fix typo: HTTP_ROW_POST_DATA → HTTP_RAW_POST_DATA.
  Make message and format arguments const char * to avoid build warning about invalid cast.
  Copy dba_*() keys before converting to string.

   The recommended way to access raw POST data is to open and use a php://input 
   stream wrapper.  It is safe to be used concurrently and more than once. 
 
+  d. Arginfo changes
+
+  The pass_rest_by_reference argument of the ZEND_BEGIN_ARG_INFO and
+  ZEND_BEGIN_ARG_INFO_EX() is no longer used. The value passed to it is ignored.
+
+  Instead a variadic argument is created using ZEND_ARG_VARIADIC_INFO():
+
+      ZEND_ARG_VARIADIC_INFO(0, name) /* pass rest by value */
+      ZEND_ARG_VARIADIC_INFO(1, name) /* pass rest by reference */
+      ZEND_ARG_VARIADIC_INFO(ZEND_SEND_PREFER_REF, name)
+          /* pass rest by prefer-ref */
+
+  ZEND_ARG_VARIADIC_INFO() should only be used for the last argument.
+
+  The following changes were applied to the zend_arg_info struct:
+
+       typedef struct _zend_arg_info {
+           const char *class_name;
+           zend_uint class_name_len;
+           zend_uchar type_hint;
+      +    zend_uchar pass_by_reference;
+           zend_bool allow_null;
+      -    zend_bool pass_by_reference;
+      +    zend_bool is_variadic;
+       } zend_arg_info;
+
+  The following changes were applied to the zend_internal_function_info struct:
+
+       typedef struct _zend_internal_function_info {
+           zend_uint required_num_args;
+           zend_uchar _type_hint;
+           zend_bool return_reference;
+      -    zend_bool pass_rest_by_reference;
+      +    zend_bool _allow_null;
+      +    zend_bool _is_variadic;
+       } zend_internal_function_info;
+
+  The CHECK_ARG_SEND_TYPE(), ARG_MUST_BE_SENT_BY_REF(),
+  ARG_SHOULD_BE_SENT_BY_REF() and ARG_MAY_BE_SENT_BY_REF() macros now assume
+  that the argument passed to them is a zend_function* and that it is non-NULL.
