maybe need to modify session garbage collector section. - eterv - 11-26-2018
I think that maybe need to modify session garbage collector section.
Session/Handlers/FileHandler.php
public function gc();
original code is ...
$pattern = sprintf(
'/^%s[0-9a-f]{%d}$/', preg_quote($this->cookieName, '/'), ($this->matchIP === true ? 72 : 40)
);
but, why 40? I can't understand this.
for example, one of my session file name is a_sessionba2o0ekqqv8ogvqonrl2u0uqg86so8fm
a_session is cookiename.
so, session id is "ba2o0ekqqv8ogvqonrl2u0uqg86so8fm". the length of this string is 32.
So, actually, in my case 32 is correct value.
and I found this code part.
in Session/Session.php
protected function configureSidLength();
after be called this function, sidRegexp value is, "[0-9a-v]{32}" (in my case)
So, I tried to modify gc part code.
Here are some code.
PHP Code:
$sid_regexp = '';
$bits_per_character = (int) (ini_get('session.sid_bits_per_character') !== false ? ini_get('session.sid_bits_per_character') : 4);
$sid_length = (int) (ini_get('session.sid_length') !== false ? ini_get('session.sid_length') : 40);
switch ($bits_per_character) {
case 4: $sid_regexp = '[0-9a-f]'; break;
case 5: $sid_regexp = '[0-9a-v]'; break;
case 6: $sid_regexp = '[0-9a-zA-Z,-]'; break;
}
$sid_regexp .= '{' . $sid_length . '}';
$pattern = sprintf( '/^%s%s$/', preg_quote($this->cookieName, '/'), $sid_regexp );
/* // Original Code
$pattern = sprintf(
'/^%s[0-9a-f]{%d}$/', preg_quote($this->cookieName, '/'), ($this->matchIP === true ? 72 : 40)
);*/
After modify it, Finally My php Garbage Collector removed garbage session files.
So, please modify this part properly.
