Bug->Doc #71873 [Ver]: Warning:zend.assertions may be completely enabled or disabled only in php.ini

Edit report at https://bugs.php.net/bug.php?id=71873&edit=1 ID: 71873 Updated by: cmb@php.net Reported by: ildar dot aim at gmail dot com Summary: Warning:zend.assertions may be completely enabled or disabled only in php.ini Status: Verified -Type: Bug +Type: Documentation Problem -Package: *General Issues +Package: *Configuration Issues Operating System: * PHP Version: 7.0.4 Block user comment: N Private report: N New Comment: > This is how it's supposed to work. Oops! Of course. Actually, the error message makes that clear ("... completely ..."). > Please, do not break an ability to enable asserts from php code. As Nikita pointed out, enabling assertions during runtime is *impossible*, if zend.assertions = -1. However, as the documentation isn't very clear about this issue, I'm changing to doc bug. Previous Comments: ------------------------------------------------------------------------ [2016-03-23 14:21:37] ildar dot aim at gmail dot com Please, do not break an ability to enable asserts from php code. In some case, developers do not have a write access to the php.ini file. This old debug code does not work after upgrade to PHP7 without //Enable assertions if (defined('DEVELOPMENT_MODE')) { // ini_set('zend.assertions', 1); // does not work without php.ini corrections assert_options(ASSERT_ACTIVE, true); assert_options(ASSERT_BAIL, false); assert_options(ASSERT_WARNING, false); assert_options(ASSERT_CALLBACK, 'func_assert_failure_handler'); } else { assert_options(ASSERT_ACTIVE, false); } ------------------------------------------------------------------------ [2016-03-23 12:56:23] nikic@php.net This is how it's supposed to work. You can't change from or to a -1 assertion level at runtime, because it controls compile-time behavior. If you want to retain the ability to change the assertion level at runtime, you should be using zend.assertions=0 in your ini, instead of zend.assertions=-1. ------------------------------------------------------------------------ [2016-03-23 12:51:23] cmb@php.net Indeed, there is obviously a contradiction in the code: <https://github.com/php/php-src/blob/php-7.0.5RC1/Zend/zend.c#L121> vs. <https://github.com/php/php-src/blob/php-7.0.5RC1/Zend/zend.c#L132>. ------------------------------------------------------------------------ [2016-03-21 17:25:10] ildar dot aim at gmail dot com Description: ------------ According to http://php.net/manual/en/ini.core.php zend.assertions is PHP_INI_ALL In spite of this fact my script generates php warninig "Warning: zend.assertions may be completely enabled or disabled only in php.ini" ------------- My info aim-server[~/tmp]$ php -i |grep -i assert zend.assertions => -1 => -1 assert.active => 1 => 1 assert.bail => 0 => 0 assert.callback => no value => no value assert.exception => 0 => 0 assert.quiet_eval => 0 => 0 assert.warning => 1 => 1 aim-server[~/tmp]$ aim-server[~/tmp]$ php -v PHP 7.0.4 (cli) (built: Mar 5 2016 09:28:27) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies with Xdebug v2.4.0, Copyright (c) 2002-2016, by Derick Rethans aim-server[~/tmp]$ Test script: --------------- error_reporting(-1); ini_set('display_errors', 1); ini_set('display_startup_errors', 1); ini_set('zend.assertions', 1); var_dump('end');die; Expected result: ---------------- string(3) "end" Actual result: -------------- PHP Warning: zend.assertions may be completely enabled or disabled only in php.ini in /home/aim/tmp/home.php on line 46 PHP Stack trace: PHP 1. {main}() /home/aim/tmp/home.php:0 PHP 2. ini_set() /home/aim/tmp/home.php:46 Warning: zend.assertions may be completely enabled or disabled only in php.ini in /home/aim/tmp/home.php on line 46 Call Stack: 0.0002 399768 1. {main}() /home/aim/tmp/home.php:0 0.0002 400280 2. ini_set() /home/aim/tmp/home.php:46 /home/aim/tmp/home.php:47: string(3) "end" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71873&edit=1
