Description:
------------
When 'register_long_arrays' is enabled and a session variable is unset
within a foreach loop over $_SESSION the session is not written out
anymore, causing the changes to the session beeing lost.
(session_unregister works nice btw.)
Reproduced on various (patched and vanilla) 5.* (including 5.2.0)
versions on GNU/Linux
Some debugging showed that actually the internal pointer (in
ps_globals' http_session_vars zval) to the session hashtable are
wrecked when doing this so this seems not to be a ext/session issue but
more of a core issue.
----
Dump in php_session_flush:
gdb> print (*ps_globals.http_session_vars).value
$5 = {lval = 0x5a5a5a5a, dval = 1.7838867517321418e+127, str = {val =
0x5a5a5a5a <Address 0x5a5a5a5a out of bounds>, len = 0x5a5a5a5a}, ht =
0x5a5a5a5a, obj = {handle = 0x5a5a5a5a, handlers = 0x5a5a5a5a}}
Reproduce code:
---------------
<?php
session_start();
var_dump($_SESSION);
$_SESSION['test'] = 'blubb';
$_SESSION['foo'] = 'test';
foreach($_SESSION as $key => $val) {
unset($_SESSION['test']);
}
var_dump($_SESSION);
?>
Expected result:
----------------
On first run:
array(9) {
}
array(1) {
["foo"]=>
string(4) "test"
}
On second run:
array(1) {
["foo"]=>
string(4) "test"
}
array(1) {
["foo"]=>
string(4) "test"
}
Actual result:
--------------
On every run:
array(9) {
}
array(1) {
["foo"]=>
string(4) "test"
}
