CE Phoenix Cart Forum

Hello

Have a site that I am testing, has many updates related to Pheonix v1.0.1.4

using two servers with PHP 7.2.34 and 10.6.19-MariaDB-log - MariaDB Server

Replicating them with GTID using master-master, now it does all work can create orders on one and it be there on the other as long as its slow rejoin, but breaks because of duplicate entry in the sessions.

Error 'Duplicate entry 'uqdteoe9k5r6qet9utlo3l5ljr' for key 'PRIMARY'' on query. Default database: 'MYDATABASE NAME'. Query: 'insert into sessions values ('uqdteoe9k5r6qet9utlo3l5ljr', '1727943797', 'sessiontoken|s:32:\"74ebfb596f3298b5dd2ca0a7b8c712b6\";cart|O:12:\"shoppingCart\":4:{s:8:\"contents\";a:0:{}s:5:\"total\";i:0;s:6:\"weight\";i:0;s:12:\"content_type\";b:0;}language|s:7:\"english\";languages_id|s:1:\"1\";currency|s:3:\"GBP\";navigation|O:17:\"navigationHistory\":2:{s:4:\"path\";a:0:{}s:8:\"snapshot\";a:0:{}}')'


Error 'Duplicate entry 't8q4v1s1fko1aorvj9e2bnreih' for key 'PRIMARY'' on query. Default database: 'MYDATABASE NAME'.

So it looks like its breaking on admin side as well as catalog.

When I look into includes\funtions\sessions it says

if ( tep_db_num_rows($check_query) > 0 ) {
$result = tep_db_query("update sessions set expiry = '" . tep_db_input(time()) . "', value = '" . tep_db_input($value) . "' where sesskey = '" . tep_db_input($key) . "'");
} else {
$result = tep_db_query("insert into sessions values ('" . tep_db_input($key) . "', '" . tep_db_input(time()) . "', '" . tep_db_input($value) . "')");
}


and admin\includes\functions\sessions.php it says

function _sess_write($key, $value) {
$check_query = tep_db_query("select 1 from " . TABLE_SESSIONS . " where sesskey = '" . tep_db_input($key) . "'");

if ( tep_db_num_rows($check_query) > 0 ) {
$result = tep_db_query("update " . TABLE_SESSIONS . " set expiry = '" . tep_db_input(time()) . "', value = '" . tep_db_input($value) . "' where sesskey = '" . tep_db_input($key) . "'");
} else {
$result = tep_db_query("insert into " . TABLE_SESSIONS . " values ('" . tep_db_input($key) . "', '" . tep_db_input(time()) . "', '" . tep_db_input($value) . "')");
}

so kind of think it is checking first before it puts another session in, but perhaps it needs to handled differently

Certainly not a coder, just a busy store owner, any pointers would be handy.

Kindest regards

Just empty your sessions table.
Do it when you have no customers on site about to buy.
