Open petervanderdoes opened 8 years ago

petervanderdoes commented 8 years ago

The error message I get: PHP Fatal error: Uncaught PDOException: SQLSTATE[HY000]: General error in /var/www/xxxx/htdocs/content/plugins/wp-db-driver/drivers/pdo_mysql.php:277

WordPress: 4.4.2 WP-DB-Driver: 2.1.0 PDO Driver for MySQL enabled Client API version mysqlnd 5.0.12-dev - 20150407

It was also reported here: https://wordpress.org/support/topic/php703-and-percona-57?replies=3. I don't have much to look into it so will see when I can fix it.

petervanderdoes commented 8 years ago

I just send a PR #106 which should fix this problem. I can't explain exactly why it solves the problem though.

markoheijnen commented 8 years ago

If that PR is how it should be solved then it is indeed weird. I also enabled PHP7 in the Travis unit tests but weirdly enough they are passing. Though the PDO unit tests do show some possible weirdness

petervanderdoes commented 8 years ago

Well I just installed PHP 7.0.4 and without the above PR everything works fine. I do also agree it's weird that there are no errors concerning this issue in travis. I also don't understand why there are some many other SQL errors in travis, but that's beside the scope of this issue.

I'm seeing these uncaught PDOException errors in my log files whenever wp-cron executes.

4 months, 3 weeks later, I was experiencing the same problem yesterday, except once I'd been logged out overnight I couldn't get into wp-admin at all. Is it so rare to be running PHP7 and want to use PDO that no-one else is reporting this problem?

PHP 7.0.8 mysql Ver 14.14 Distrib 5.7.16 WordPress 4.6.1 WP DB Driver Version 2.1.0

markoheijnen commented 7 years ago

Will look into it soon. At least before WordPress 4.7 has been released.
