From af02bde61c2a5af1ae64cac09ffe2b25237aa58e Mon Sep 17 00:00:00 2001 Patch-Origin: https://github.com/mkoppanen/php-zmq/commit/af02bde61c2a5af1ae64cac09ffe2b25237aa58e From: Alex/AT Date: Mon, 10 Dec 2018 06:02:27 +0300 Subject: [PATCH] PHP 7.3 compatibility and bugfixes - Define new GC_ADDREF/DELREF/SET_REFCOUNT macros for older PHP versions and use them instead of direct GC reference counter access - Fixup all necessary 'long' type parameters to 'zend_long', PHP 7.3 makes it mandatory, also fixup some direct function implementations to accept the same - In php_zmq_recv(), zend_string_init() was wrongly called with third parameter as '1', marking new string with IS_STR_PERSISTENT, this caused heap corruption and/or segfaults with PHP 7.3 and could possibly cause other sorts of bugs under any 7.x version With ZVAL_STRINGL macro, this last '1' parameter meant to copy the string and was seemingly erroneously moved to zend_string_init(). zend_string_init() copies string by default, and last parameter has totally different meaning here - In poll(), flag ZVAL separation on passed arrays (PHP 7.3 makes it mandatory) - Test 19 (exception on connect callback with forced reference parameter): skip on PHP 7.1 and higher, PHP >= 7.1 started to fallback to passing argument by value instead of failing - Test 21 (warning generation from callback): it is ok, but PHP 7.3 uses 'int' instead of 'integer' for constants, so allow any word in place of the word 'integer' --- php_zmq.h | 6 ++++ tests/019-callbackinvalidsignature.phpt | 3 +- tests/021-callbackwarning.phpt | 2 +- zmq.c | 40 ++++++++++++------------- zmq_sockopt.c | 4 +-- 5 files changed, 30 insertions(+), 25 deletions(-) diff --git a/php_zmq.h b/php_zmq.h index ef50bfb..3833967 100644 --- a/php_zmq.h +++ b/php_zmq.h @@ -44,6 +44,12 @@ #include "php.h" +#if PHP_VERSION_ID < 70300 +#define GC_ADDREF(p) ++GC_REFCOUNT(p) +#define GC_DELREF(p) --GC_REFCOUNT(p) +#define GC_SET_REFCOUNT(p, rc) GC_REFCOUNT(p) = rc +#endif + extern zend_module_entry zmq_module_entry;
