Piwik Tracker throws SQL exceptions when using a boolean value for a tinyint(1) field #2153

/core/Tracker/Db/Pdo/Mysql.php#L170 with out of the box MySQL 5.5.9 throws

SQLSTATE[HY000]: General error: 1366 Incorrect integer value: '' for column 'visitor_returning' at row 1

This happens because $parameters(3) is a bool variable and 'visitor_returning' is a tinyint(1) field.

One of the places this value is set is in /core/Tracker/Visit.php#L437.


'visitor_returning'         => $visitCount > 1 || $this->isVisitorKnown(),


'visitor_returning'         => $visitCount > 1 || $this->isVisitorKnown() ? 1 : 0,

suppresses the exception and confirms the issue.

What is the best way to go from here ?


This is a weird regression. The MySQL docs says BOOL/BOOLEAN is a synonym for TINYINT(1), and TRUE and FALSE are aliases for 1 and 0, respectively. Also, looking at Piwik's schema, visitor returning is "TINYINT(1) NOT NULL". I would have expected PHP's type conversion to yield 1 for true.

<?php  var_dump( true == 1);

Well... I'm ok with the change. I assume other TINYINT columns are affected?
