ID: 64239 Updated by: dmi...@php.net Reported by: kusmierz at o2 dot pl Summary: Debug backtrace changed behavior since 5.4.10 or 5.4.11 Status: Assigned Type: Bug Package: *General Issues Operating System: Ubuntu,Debian,Windows PHP Version: 5.4.11 Assigned To: dmitry Block user comment: N Private report: N New Comment: Laruence, you are right. Reflection, debug_backtrace() and get_class_methods() are affected. It would be good to fix it, however, I don't see a good way to do it, and I don't like to introduce a new hack. (e.g. resolving alias name by looking into hash table key). Actually we have the same situation with class aliases. In general, we can fix it in 5.5 using some inefficient way (e.g. add op_array->alias_function_name) Any ideas are welcome. Previous Comments: ------------------------------------------------------------------------ [2013-02-19 04:14:26] larue...@php.net seems due to the new implemention of trait, not only debug_backtrace, I think the reflection is also affected. dmitry, do you think this should be fixed? thanks ------------------------------------------------------------------------ [2013-02-18 20:48:20] kusmierz at o2 dot pl Description: ------------ The debug_backtrace behavior has been changed since 5.4.9. Previously first method in backtrace array was an alias name (Bmethod in my example) which seems to be ok as only one possibility to check name of trait's aliased method name (see also #61033). Now it returns trait's method name (t2method), which is incorrect in my mind - I can't now check which method was originally called. Test script: --------------- class A { use T1; public function test() { $this->backtrace(); } } class B { use T2 { t2method as Bmethod; } } trait T1 { protected function backtrace() { $b = new B(); $b->Bmethod(); } } trait T2 { public function t2method() { var_dump(debug_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS, 1)); } } $a = new A(); $a->test(); Expected result: ---------------- // php 5.4.9 array(1) { [0]=> array(5) { ["file"]=> string(24) "/home/adam/test/test.php" ["line"]=> int(25) ["function"]=> string(7) "Bmethod" // OK; ["class"]=> string(1) "B" ["type"]=> string(2) "->" } } Actual result: -------------- // php 5.4.11 array(1) { [0] => array(5) { 'file' => string(19) "/home/adam/test.php" 'line' => int(25) 'function' => string(8) "t2method" // ! 'class' => string(1) "B" 'type' => string(2) "->" } } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64239&edit=1
