From 3e963f8eb44863ef3d758eabe791190b0fd7bb9a Mon Sep 17 00:00:00 2001 From: Remi Collet Date: Tue, 10 Dec 2013 16:07:16 +0100 Subject: [PATCH] Fixed Bug #66218 zend_register_functions breaks reflection Functions registered using zend_register_functions instead of zend_module_entry.functions are not seen on reflection. Ex: additional_functions from api_module_entry. Ex: in CLI, dl, cli_set_process_title and cli_get_process_title Note: - also affects functions overrided in extension (should be be reported in extension, where overrided, not in original extension) - also allow extension to call zend_register_functions for various list (instead of having a single bug list) --- NEWS | 1 + Zend/tests/bug66218.phpt | 21 +++++++ Zend/zend_builtin_functions.c | 51 ++++++++++------- ext/reflection/php_reflection.c | 66 +++++++++------------- .../tests/ReflectionExtension_bug66218.phpt | 21 +++++++ 5 files changed, 101 insertions(+), 59 deletions(-) create mode 100644 Zend/tests/bug66218.phpt create mode 100644 ext/reflection/tests/ReflectionExtension_bug66218.phpt diff --git a/Zend/tests/bug66218.phpt b/Zend/tests/bug66218.phpt new file mode 100644 index 0000000..af7a5ab --- /dev/null +++ b/Zend/tests/bug66218.phpt @@ -0,0 +1,21 @@ +--TEST-- +Bug #66218 zend_register_functions breaks reflection +--SKIPIF-- + +--FILE-- + +Done +--EXPECTF-- +dl Ok +Done diff --git a/Zend/zend_builtin_functions.c b/Zend/zend_builtin_functions.c index 04f4ebe..12a8fb2 100644 --- a/Zend/zend_builtin_functions.c +++ b/Zend/zend_builtin_functions.c @@ -2442,36 +2442,49 @@ ZEND_FUNCTION(extension_loaded) Returns an array with the names of functions belonging to the named extension */ ZEND_FUNCTION(get_extension_funcs) { - char *extension_name; - int extension_name_len; + char *extension_name, *lcname; + int extension_name_len, array; zend_module_entry *module; - const zend_function_entry *func; - + HashPosition iterator; + zend_function *zif; if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s", &extension_name, &extension_name_len) == FAILURE) { return; } - if (strncasecmp(extension_name, "zend", sizeof("zend"))) { - char *lcname = zend_str_tolower_dup(extension_name, extension_name_len); - if (zend_hash_find(&module_registry, lcname, - extension_name_len+1, (void**)&module) == FAILURE) { - efree(lcname); - RETURN_FALSE; - } + lcname = zend_str_tolower_dup(extension_name, extension_name_len); + } else { + lcname = estrdup("core"); + } + if (zend_hash_find(&module_registry, lcname, + extension_name_len+1, (void**)&module) == FAILURE) { efree(lcname); + RETURN_FALSE; + } - if (!(func = module->functions)) { - RETURN_FALSE; - } + zend_hash_internal_pointer_reset_ex(CG(function_table), &iterator); + if (module->functions) { + /* avoid BC break, if functions list is empty, will return an empty array */ + array_init(return_value); + array = 1; } else { - func = builtin_functions; + array = 0; + } + while (zend_hash_get_current_data_ex(CG(function_table), (void **) &zif, &iterator) == SUCCESS) { + if (zif->common.type==ZEND_INTERNAL_FUNCTION + && zif->internal_function.module == module) { + if (!array) { + array_init(return_value); + array = 1; + } + add_next_index_string(return_value, zif->common.function_name, 1); + } + zend_hash_move_forward_ex(CG(function_table), &iterator); } - array_init(return_value); + efree(lcname); - while (func->fname) { - add_next_index_string(return_value, func->fname, 1); - func++; + if (!array) { + RETURN_FALSE; } } /* }}} */ diff --git a/ext/reflection/php_reflection.c b/ext/reflection/php_reflection.c index c4a7c55..803b12b 100644 --- a/ext/reflection/php_reflection.c +++ b/ext/reflection/php_reflection.c @@ -1105,29 +1105,26 @@ string_free(&str_constants); } - if (module->functions && module->functions->fname) { + { + HashPosition iterator; zend_function *fptr; - const zend_function_entry *func = module->functions; - - string_printf(str, "\n - Functions {\n"); + int first = 1; - /* Is there a better way of doing this?
