Bug description:Debug backtrace changed behavior since 5.4.10 or 5.4.11
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) "->"
}
}
