Issues upgrading from 4.5.7 - Invalid default value for 'Posted'

Something for the collective knowledge base …

Went to upgrade a local (Mac hosted) website from 4.5.7 to 4.7.3 and bang! A thousand errors.

Reverted back to 4.5.7, this time upgraded to 4.6.2 and one of the old chestnuts went pop:

User_Error "Invalid default value for 'Posted'"
in /Users/adi/Sites/vanilla/textpattern/lib/txplib_db.php at line 409.
textpattern/lib/txplib_misc.php:1676 adminErrorHandler()
updateErrorHandler()
textpattern/lib/txplib_db.php:409 trigger_error()
textpattern/lib/txplib_db.php:536 safe_query()
textpattern/update/_to_4.6.0.php:28 safe_alter()
textpattern/update/_update.php:90 include()
textpattern/index.php:180 include()

Tried Update checks for zeroed dates cause admin area to break – didn’t fix it.

Tried Zero dates fix attempt (which is designed to temporarily switch off MySQL STRICT mode) – didn’t fix it.

Head in hands time … but after hacking around I realised that the tweak in the above “Zero dates fix attempt” wasn’t actually changing the MySQL mode.

What I found is that when MySQL mode is set to TRADITIONAL – it has TRADITIONAL in the list:

SELECT @@GLOBAL.sql_mode;
+------------------------------------------------------------------------------------------------------------------------------------------------------+
| @@GLOBAL.sql_mode                                                                                                                                    |
+------------------------------------------------------------------------------------------------------------------------------------------------------+
| STRICT_TRANS_TABLES,STRICT_ALL_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,TRADITIONAL,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |
+------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

Consequently, if you try to change the mode thus:

SET GLOBAL sql_mode = "STRICT_TRANS_TABLES,STRICT_ALL_TABLES,ERROR_FOR_DIVISION_BY_ZERO,TRADITIONAL,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION";

Nothing actually changes!

You need to lose “TRADITIONAL” from the list.

Amended the first part of the above “Zero dates fix attempt” workaround to:

if ($sql_mode = getThing('SELECT @@SESSION.sql_mode')) {
	$tmp_mode = implode(',', array_diff(
		do_list_unique($sql_mode),
		array('NO_ZERO_IN_DATE', 'NO_ZERO_DATE’, ‘TRADITIONAL’)
		));
	safe_query("SET SESSION sql_mode = '".doSlash($tmp_mode)."'");
}

… and bingo! Upgrade to 4.6.2 completed successfully & for that matter a subsequent hop to 4.7.2 was error free also.

I would imagine going straight from 4.5.7 to 4.7.3 or beyond would be fine with the above tweak also.

Ooh, that’s interesting. Thank you for your investigative powers and diligence to find a solution. Never seen TRADITIONAL in use before. Will patch core today as you suggest. Thank you.

No probs – if there’s a hole to fall in, I’ll find it. The least I can do is put up a sign!

Isn’t that the same problem described here with MariaDB?

Maybe, but I’m not sure totally dumping sql_mode is safe.
