[PHP-DEV] OnXXXXX handlers not called in ZTS environment

[Uwe Schindler]

When changing a ini entry with zend_alter_ini_entry during runtime the 
Callback routines OnUpdateXXXX are never called. This problem only exists 
in multithreaded environments.
I think that the handler field in the entry is not copied when creating the 
copy of the ini entries after creating a new thread ressource:

#ifdef ZTS
ZEND_API int zend_copy_ini_directives(TSRMLS_D)
{
        zend_ini_entry ini_entry;
        EG(ini_directives) = (HashTable *) malloc(sizeof(HashTable));
        if (zend_hash_init_ex(EG(ini_directives), 
registered_zend_ini_directives->nNumOfElements, NULL, NULL, 1, 0)==FAILURE) {
                return FAILURE;
        }
        zend_hash_copy(EG(ini_directives), registered_zend_ini_directives, 
NULL, &ini_entry, sizeof(zend_ini_entry));
        zend_ini_refresh_caches(ZEND_INI_STAGE_STARTUP TSRMLS_CC);
        return SUCCESS;
}
#endif

I am not very familar with the Zend engine so I do not know how to 
implement this, but the following command does not ever call the OnUpdate 
handler:
zend_alter_ini_entry(....., PHP_INI_SYSTEM, PHP_INI_STAGE_RUNTIME)
